Executive Summary

A. Introduction

1. The Government of Tamil Nadu proposes to upgrade its road network falling in the conceptual influence area of the Chennai Kanyakumari Industrial Corridor Project (CKICP), which aims at improving the transport infrastructure, such as the connectivity of industrial nodes to ports, urban areas and critical hinterland areas. The Highways and Minor Ports Department (TNHD) of Tamil Nadu has been mandated to undertake improvement and upgradation of various State Highways at different locations in the State under this project and will serve as the Executing Agency (EA). As part of this mandate, the Construction and Maintenance (C&M) Wing of TNHD has identified the 16 road sections for improvement totally totaling about 590 km spread across the State. The project will be financed through a project loan from the Asian Development Bank (ADB) under Tamil Nadu Industrial Connectivity Project (TNICP). The Project Implementation Unit (PIU) formed within TNHD will be the Implementing Agency (IA).

2. This Initial Environmental Examination (IEE) report is prepared for Kumbakonam to Sirkazhi section of SH-64. The length of the project road is 36.779 km. The project road is located in Thanjavur, and Mayiladuthurai districts of Tamil Nadu. The project road starts at Km 2+875, having latitude 10o57’34”N and longitude 79o22’44”E in Kumbakonam, Thanjavur district of Tamil Nadu and ends at Km 51+577 having latitude 11o13’5”N and longitude 79o44’15”E in Sirkazi, Nagapattinam district of Tamil Nadu.

3. As per provisions of the EIA Notification 2006 (amended in 2020), all new state highway expansion projects except in hilly terrain (above 1,000m above mean sea level or AMSL) and or notified ecologically sensitive areas fall under Category B and does not require environmental clearance from the State Environmental Impact Assessment Authority (SEIAA). The project road section is a state highway located on plain terrain with elevation less than 1000m AMSL. The project road alignment is not passing through any forest area and notified protected area. Thus, the project road does not fall under the purview of environmental clearance under EIA notification 2006 of MOEFCC.

B. Description of the Project

4. The proposed road section is part of SH-64 in Tamil Nadu State. The existing road is of two-lane carriageway with earthen shoulder configuration type. Width of RoW is not uniform along the project road and the carriageway/roadway width of the road is in range of 5.5m to 7m. The proposed RoW for the 2 lane configuration has been fixed as 16.0m in urban built-up areas and open areas. For the bypass section in green fields has been fixed as 30m.

5. There is one bypass proposed at Vaitheeswaran Kovil from existing chainage of km 47/323 (Design Ch. 47+100) to km 51/958 (Design Ch. 51+250) with a design length of 4.15 km. Minor realignments are proposed at existing chainages from km 13+600 to km 13+900, km 41+660 to km 42+330, Km 43+330 to Km 43.550 and km 45+300 to km 45+558. The additional land required for the improvement of project road is 18.0182. along the alignment and for proposed bypass sections.

6. There are seven minor (no major) bridges, and 47 Culverts (18 Pipe, 28 slab and 1 Box) on the existing project road. Based on the inventory & condition survey of structures, latest circulars of MoRT&H & IRC circulars / codal provisions and keeping in view of the ToR, 5 minor ii

bridges are retained, 1 is proposed for widening and 2 will be newly constructed. Three new minor bridges are proposed (Km 43+814 in Linear stretch), km 47+700 , km 48+928 along the proposed bypass for Vaitheeswaran Kovil. One New Major Bridge at Km 13+739.19 pipe culverts are proposed to box culverts, 27 slab culverts will be reconstructed to box culverts. 1 existing box culvert is retained and widened. 35 new box culverts are proposed (19 along existing SH64 and 16 along the proposed bypass).

C. Description of the Environment

C.1 Physical Environment

7. Meteorological Conditions: The project road section is located in two districts, Thanjavur and Nagapattinam; the details of physical environmental parameters of the district are:

Feature Kumbakonam-Sirkazhi section of SH-64 Average Annual Rainfall The average annual rainfall in Thanjavur is about 888.78 mm while the average rainfall in Nagapattinam is 1306.6 mm. The Nagapattinam district receives more rainfall than Thanjavur district. Concentration of October, November and December precipitation Humidity The project area of influence area (PAI) has humid to sub-humid climate. The minimum humidity recorded during the study period along the project road were 69%. The maximum humidity recorded was 99%. The overall average ambient humidity during the period was 86.25%. Wind The daily averaged wind speed in project region is about 3.3 kmph. The predominant wind direction is NE. Temperature Nagapattinam: The average maximum temperature during the summers remains around 35°C. The winters are relatively very pleasant when average minimum temperature remains around 20°C. Thanjavur: The temperatures are highest on average in May, at around 31.6 °C. At 25.2 °C on average, January is the coldest month of the year. The mean maximum temperature of the district shows variation between 36.6° in May and 26.7°C.

8. Geography and Topography: The project region has plain topography having an altitude in the range of 1-150m above MSL. The project road traverses in plain terrain passing through rural areas as well as many intermittent semi-urban and urban settlements. The elevation of project road varies from 3m to 28m.

9. Landuse: The landuse pattern of the project district is mostly of agriculture area. The forest cover in both the district is less than 2% while the net area sown the project districts is more than 50%. Most of the land surrounding project road is agricultural fields with intermittent rural/urban built- up structures. Also, it is to be noted that there is no forest land within 500m of project road.

10. This project road passes through many villages and towns namely Thiruvalluvar nagar, New Agraharam, Ammachatram,Umamaheswarapuram, Thirubhuvanam, Thiruvidaimaruthur, Govindapuram, Aduthurai, Thyagarajapuram, Narsasingampettai, Thiruvalangudi, iii

Sivaramapuram Agraharam, Kathirmangalam, Gunathalaipad, Kambar colony, Senniayanallur, and Aryapuram, Malliyam, Solasakranallur, Athukudi Dharmanathapuram, Sirkhazi.

11. Geology: Geologically, the entire state can be broadly classified into hard Rock or Crystalline Formation and Sedimentary Formations. The State accounts for 81% lignite, 75% vermiculite, 69% dunite, 59% garnet, 52% molybdenum and 30% titanium mineral resources of the country. The state of Tamil Nadu in the peninsular shield is a zone of low to moderate seismic activity with a sparse historical record of significant earthquakes. The project influence area and study area fall in seismic zone II.

12. Soil: The entire Nagapattinam district is covered by semi-consolidated formations consisting of sand, silt and clays. The major part of the district is covered by black clay and isolated patches of brown clay loam in the area bordering the NE boundary of Karaikal Region are seen. Some patches of Arenacious soils are also found along the coastal line. The Thanjavur district is occupied by different geological formations. The different types of soil are derived from the formations are Quaternary, Pliocene, Miocene and Cretaceous.

13. Soil samples were collected at 4 locations from agriculture fields (km 5+000, km 22+200, km 43+100 and km 53+000) in Kumbakonam - Sirkazhi road section of SH64 during DPR preparation. The pH levels of the soil samples show that soil is neutral at all locations along the road section alignment. The soil type is clay and loamy clay in texture. The soil has good electrical conductivity. Based on water retention characteristics, a portion of project region have soils that have low water retention and rest portion have soil that have very high water retention characteristic.

14. Water Resources and Hydrology: The project influence area is drained by tributaries of Cauvery and Kodilam Rivers. Cauvery River is flowing parallel to the project road from the road starting point to km.35+600 on the left hand side. And Nattar river is flowing on right hand side. All being minor irrigational canals the bridges constructed over these are minor bridges except at design chainage at km 13+756 (Newly Proposed Major Bridge) and no overtopping conditions were observed on these bridges. The alignment crosses minor streams and irrigation canals.

15. Water Quality: In order to represent the true profile of the project area, samples from surface water source through which the project road runs were collected and analyzed as per IS- 2488 (Part I-V). Ground water (drinking water) and surface water samples were analyzed as per IS: 10500-1991. Water quality was monitored at six locations to represent the profile of the project area, three each for surface and ground water. Surface water quality results show that the pH of the water in the region is well within permissible limits (6.5 – 8.5). The samples collected from ground water shows the parameter is well within the permissible standards.

16. Air Quality: Ambient air quality for particulate matters (PM10 and PM2.5), SO2, NOx & Pb was monitoring at two locations along the project road. It is found from the results that PM10 concentration at all monitoring locations were well within the permissible limits for residential zone i.e. 100 μg/m3 prescribed by MOEFCC but slightly higher than World Bank EHS guideline limit of 50 μg/m3. The highest value of PM 10 is observed at Natham Village Site (61.9μg/m3), which is well within permissible limits. Similarly, PM2.5 concentration is highest at Natham Village Site and is 33.1 μg/m3 well within the permissible limit i.e. 60 μg/m3 prescribed by MOEFCC but slightly higher than the World Bank EHS guideline limit of 25 μg/m3. Other parameters monitored i.e. NOx, SO2 were found within the permissible limits for all the locations. Overall, the air quality in the project area is good. iv

17. Noise Levels and Vibrations: Noise levels were monitored at five locations along the project road. The maximum recorded day time noise level is 78.2 dB(A) and night time noise level is 71.5 dB(A) along the project alignment. The equivalent noise levels for day time ranges between 71.37-72.24 dB(A) and equivalent noise levels for day time ranges between 63.72- 64.93 dB(A). The recorded noise level is higher than the permissible limits for residential area of 55 dB(A) and 45 dB(A) for daytime and nighttime, respectively. This noise is mainly from vehicular traffic and local domestic/commercial activities.

C.2 Biological Environment

18. The RoW of the project road do not fall under any forest area and thus does not attract forest land diversion. The project road does not fall in core or buffer zone of any protected area (National Park, Wildlife Sanctuary, Reserved Forest, Biosphere Reserve, Wetland).

19. A total of 1466 trees girth size (>30cm) fall within formation width of project road, which will be affected due to road widening. The dominant tree species along project road are Banyan, Peepal, Badham, Bamboo, Banana, Coconut, Mahua, Guava, Coral tre, Sweet Tamarind, Konrai, Mango, Marutham, Plum, Neem, Netling, Indian Mulberry, Kadam, Pipal, Portia, Pungan, Tamarind, Teak, Samanea saman, Jackfruit, Rain tree, Gulmohar, Palm and Bel. No tree along road side fall in CITES list of plant. One species of Saraca asoca (Ashok) is found as Vulnerable. Other flora observed along the project road are either least concern or has not yet been assessed for the IUCN Red List.

There is no presence of any fauna species listed in Schedule I of the Wildlife (Protection) Act, 1972 of Government of India.

C.3 Socio-economic Environment

21. The project road falls under districts of Tamil Nadu state, Mayiladuthurai (separated from Nagapattinam on March 2020) and Thanjavur.

22. According to 2011 census, Nagapattinam district had a population of 1,616,450 with a sex-ratio of 1,025 females for every 1,000 males, much above the national average of 929. A total of 165,245 were under the age of six, constituting 84,335 males and 80,910 females. Scheduled Castes and Scheduled Tribes accounted for 31.54% and .23% of the population respectively. The average literacy of the district was 75.04%, compared to the national average of 72.99%.

23. Thanjavur district had a population of 2,405,890 with a sex-ratio of 1,035 females for every 1,000 males, much above the national average of 929. A total of 238,598 were under the age of six, constituting 121,949 males and 116,649 females. Scheduled Castes and Scheduled v

Tribes accounted for 18.91% and .15% of the population respectively. The average literacy of the district was 74.44%, compared to the national average of 72.99%.

24. Agriculture plays a vital role in the State’s economy. Paddy is the main crop in both the project districts while pulses are also significantly grown in Nagapattinam District. The paddy crops are prominently seen in on both sides of the project road.

25. No archaeological sites or historical monuments of state importance notified under Ancient and Historical Monument and Archaeological Sites and Remains Act, 1966 of Tamil Nadu nor of national importance notified under The Ancient Monuments and Archaeological Sites and Remains Act 1958 of India are located along the project road section.

D. Consultation, Disclosure and Grievance Redress Mechanism

26. In accordance with ADB’s Safeguard Policy Statement (SPS) 2009 public consultations were held, as part of the IEE study. Consultation undertaken with project beneficiaries, local/ government officials, community leaders, women groups, stakeholders in corridor of impact and people likely to be affected due to the project on various issues affecting them and incorporation of various measures pertaining to environmental issues based on the responses from the people. Both formal and informal modes of consultation were used in the public consultation process for the project.

27. Consultation with the stakeholders, beneficiaries, and community leaders were carried out using standard structured questionnaires as well as unstructured questionnaires. In addition, focused group discussions (FGDs) and personal discussions with officials, on-site discussion with project affected stakeholders, and reconnaissance visits have also been made to the project areas. The attempts were made to encourage participation in the consultation process of the Government officials from different departments that have relevance to the project. Same way, local people from different socio-economic backgrounds in the villages as well as urban areas along the road alignment and at detours, residents near the existing road, women representatives, local commuters, and other concerned were also consulted.

28. In compliance with ADB’s SPS requirements consultation will be continued throughout the project process. The consultations were conducted during preparation of the IEE. The official consultation with the key stakeholders was undertaken in the months of January 2016. In total over 3 consultation session were organized along SH-64 project road. The public consultation meetings were organized Kumbakonam, Vaitheeswaran Koil and Mayiladuthuai to disseminate the information regarding widening and strengthening of road SH-64, respectively by the officers of Highways Department, Government of Tamil Nadu and staff of DPR consultant. Various officials consulted include TNHD Officials, Forest Officers, Environmental Officers from pollution control board, statistical officer in the project areas etc. Besides interview surveys, focused group discussions (FGDs) were organized at key locations along the project road.

29. Total 192 people were involved in consultation. Most of the people interviewed strongly support the project. The people living in the entire project area expect the different project elements to facilitate transport, employment, boost economic development and thereby provide direct, or indirect, benefits to themselves.

30. A Grievance Redress Mechanism (GRM) will be established by TNHD prior to mobilization of contractors to address grievances related to the implementation of the project, particularly regarding the EMP. Through the GRM, responsible parties will acknowledge, vi

evaluate, and respond to the complainant with corrective action proposed using understandable and transparent processes that are gender responsive, culturally appropriate, and readily accessible to all segments of the affected people.

31. Records of grievances received, corrective actions taken, and their outcomes will be properly maintained and form part of the quarterly progress reports (QPR) and semiannual environmental monitoring report to ADB. Depending on the nature and significance of the grievances or complaints, the grievance redress mechanism (GRM) will comprise procedures to address grievances i) first Regional Level and ii) State Level at the Grievance Redress Committee (GRC). Most serious complaints which cannot be addressed at the field level will be forwarded to the executing agency level and to GRC level. A two-tier GRM will be established. Regional Level Project GRC will be chaired by the TNHD Divisional Engineer concerned and would comprise of TNHD Environment Wing Assistant Environment Specialist, Project Manager of EPC contractor and Resident Engineer of CSC concerned. Complaints that cannot be resolved at the field level within 7 days will be elevated to the State Level Project GRC. It will serve as appellate authority and will be chaired by the Chief Engineer and will comprise the Superintending Engineer concerned, Environment Specialist, Team Leader of CSC concerned, Project Manager from Project Management Services of CSC-01 and Authorized Representative from EPC contractors, as needed. Grievance response period for all GRCs is 3 weeks.

32. As project executing agency, TNHD will be responsible for the disclosure of this IEE in compliance to ADB’s Access to Information Policy 2018 and ADB SPS 2009. The IEE Report will be disclosed in the English language in the office of TNHD and concern divisional engineer office. The report will also be made available to interested parties on request from the office of the TNHD. Since this is environment Category B project, the IEE report will also be disclosed to the public through the ADB website.

E. Project Benefits

33. The key positive environmental impacts of the project include improved vegetation cover, increase in area of good quality habitat by tree plantation 1:10 tree removed for the project through compensatory afforestation, which will be fully realized in 10-15 years and improvement of infrastructure along the project area. Further, the implementation of various project items is envisaged to have the following direct benefits: • better connectivity to key locations within State; • smooth flow of traffic on State Highway Network; • improved quality of life for the rural population in the project influence: this as a result of better access to markets, health, education and other facilities; and the derived stimulus for local economic activity; • a more efficient and safe road transport system: through reduced travel times, reduced road accidents, reduced vehicle operating and maintenance costs and reduced transportation costs for goods; • the facilitation of tourism.

F. Anticipated Environmental Impacts and Mitigation Measures

34. Based on analysis of project activities and environmental baseline conditions 15 valued environmental components (VECs) under physical, biological and social environment were identified. Impacts on each of these VECs during pre-construction and design stage, construction stage and operation stage was carried out. Impacts were determined to be minor, vii moderate or major based on a rating criterion of sensitivity of the VEC, duration of impact, area of impact and severity of impact.

35. Most negative impacts are of minor to moderate risk. There is no potential impact with high risk identified during project implementation. Negative impacts with moderate risks include removal of trees, noise and impacts on air quality during construction and operation stages, occupational and community health and safety. These impacts are largely short term and expected to occur during construction, with some minor induced and residual impacts expected to occur during operation.

36. The loss of land under the agriculture use for bypass and realignment section and the 1466 trees will be compensated under a mandatory compensatory scheme under the government wherein total 14660 trees (1:10 ratio) will be planted throughout the entire Project Road.. This mandatory compensation scheme is expected to result in the creation of good vegetation cover along the road section.

37. Other moderate and minor negative environmental impacts include dust; pollution of air and water; noise and disturbance for local communities during construction; 18.0182 ha. land acquisition and relocation of 89 private structures; inconveniences caused by shifting of utilities; soil erosion, contamination and siltation of surface water, waste and spoils disposal.

38. These will be addressed through various mitigation measures included in the EMP such as regular sprinkling of water; enforcement of construction time limits; regular monitoring of air, water and noise; payment of compensation to affected people in accordance with the entitlement matrix in the Resettlement Plan (RP); regular public communication on shifting of utilities; enforcement of health and safety requirements in the work sites and camps; implementation of slope stabilization measures; management of solid and liquid waste and chemicals and other measures.

G. Environmental Management Plan

39. A fully budgeted environmental management plan has been prepared for mitigation/management/ avoidance of the potential adverse impacts and enhancement of various environmental components along the project road section. For each mitigation measures to be carried out its location, timeframe, implementation and overseeing/ supervising responsibilities has been identified. Monitoring plan for construction and operation phase has been framed to ensure effective implementation of EMP.

40. The monitoring program included performance indicators for wildlife, water, air, and noise level monitoring, frequency of monitoring, and institutional arrangements of the project in the construction and operation stages, along with the estimated cost. The reporting system included roles and responsibilities of each party involved in the project implementation i.e. PIU, CSC, Contractor(s), external monitor and reporting mechanisms during implementation and operation phases.

41. The monitoring program includes regular site inspections and checks by the PIU and FIUs under TNHD. The CSC will conduct weekly and joint PIU quarterly site inspections to monitor implementation of the EMP. The CSC Environmental Specialist will monitor implementation of the EMP. viii

42. An environmental management budget of INR 4.38 million (US$ 0.58 million) has been estimated for implementation of the EMP. This budget also includes cost of environmental monitoring and associated trainings.

H. Conclusions and Recommendations

43. The project road (Kumbakonam - Sirkazhi Road section of SH-64) proposed for the improvement is classified as environment Category B project as per ADB SPS requirements. Environmental screening and assessment of likely impacts and rating of risks shows that with implementation of mitigation measures and habitat improvement activities the project will not result in significant residual environmental impacts.

44. A number of potential adverse impacts have been identified on issues related to dust, noise, pollution, soil erosion, waste, occupational health and safety, community health and safety and biodiversity. Most impacts were assessed to be of low to moderate risk. Potential impacts on biodiversity were assessed to be of medium risk. Biodiversity impacts include loss of about 1446 trees due to widening of road. There are no protected areas located within 10km radius of the road section.

45. Mitigation measures have been proposed and budgeted to address all the above identified impacts and risks in the EMP. As part of the EMP, environment management actions have also been recommended to mitigate environment related risks.

46. The EMP is a living document and will be subject to revision following finalization of the detailed design by the EPC. The EMP may undergo further revision during project construction if there is any change in project design and occurrence of unanticipated impacts. The environmental mitigation measures are itemized in the EMP and the Executing Agency (TNHD) shall ensure that the most recent EMP and EMoP are included in the civil works contract agreement.

C. Background of the Present Report

6. This IEE report is prepared for the project road in order to identify the baseline environmental status of the project road alignment, assess impacts due to the proposed widening of the road on various environmental parameters and preparation of environmental management plan to mitigate the negative impact on these parameters.

7. The initial environmental examination study was prepared between the months of November 2019 to August 2020 to meet ADB’s Safeguards policy requirements. This is the draft IEE report prepared to fulfil ADB’s SPS 2009 requirements for financing the Project. The detailed engineering design report has been prepared by M/s. Sheladia Associates Inc. The initial environmental examination report is prepared by TNHD as the EA with the help of independent environmental specialist supported by ADB technical assistance.

D. Objective and Scope of the Study

8. This IEE report documents the environmental assessment of the Kumbakonam to Sirkazhi (SH-64)road project and identifies the environmental issues to be considered in the project planning and design stages. In this report, the different activities that are likely to take place to achieve the project objectives have been analysed. Potential impacts that may accompany them have been identified, assessed for significance, and concomitant avoidance, mitigation, and compensation measures were prepared in consultation with stakeholders. The IEE addresses the environmental management requirements of the Government of India (GOI) and ADB. Specifically, this report-

• provides information about the baseline environmental setting of the project. • provides information on potential environmental impacts of the proposed project activities with its magnitude, distribution and duration and sensitivity of receptors. • provides information on required mitigation measures with cost to minimize the impacts. 3

• analyses the alternatives options considering alternative locations, designs, management approaches for selection of most feasible and environmental acceptable options. • provides details of stakeholder’s consultations. • designs an environmental management and monitoring plan with institutional responsibilities measures for effective implementation of mitigation measures proposed and provides addressing grievances.

9. The environmental studies have been confined to the situation around the deemed project area of influence caused by constructional and operational facilities along the proposed road sections. The IEE is based on proposed road alignment and key construction activities involved such as site clearing, removal of trees, excavation, filling, grading and embankment formation, excavation for utility trenches, subgrade preparation, base course and asphalt overlay, shoulder, and construction of permanent structures like retaining walls, culverts and drains. The IEE also covered ancillary activities like camp site establishment and maintenance, sourcing of materials, and operation of equipment like rock crusher and hot mix plants. The corridor of impact is taken as 10 meters either side of the proposed alignment (from edge of the proposed road) including RoW of 16 meters for urban stretches, 23 meters for rural areas, and 30 meters for bypasses. However, the study area impact zone is considered up to 10 km aerial distance on both sides of road alignment to allow for coverage of indirect and induced impacts and a larger analysis of land use and other environmental features. Assessment is carried out on the following environment components: terrestrial and aquatic ecology, soil, water, air, noise, and socio-economic aspects. The project area of influence (PAI) was determined as the ROW plus 500m on either side of the road.

10. The following sections of the report discusses the methodology adopted by the consultants in conducting the IEE study and presents the results of the same.

E. Methodology Adopted for IEE Study

11. The Initial Environmental Examination (IEE) study has been carried out in accordance with the requirements of the ADB’s Safeguard Policy Statement (SPS 2009). The Government of India guidelines for Rail/Road/Highway projects; EIA notification 2006 and its amendment of MOEFCC and the Highway Sector EIA guidance manual 2010 have also been followed in the process of this environmental assessment. The study methodology has been adopted in such a manner to ensure that environmental concerns are given adequate weightage in the selection of alignment and design of proposed road improvements. The study in this project employs an iterative approach in which potential environmental issues have been examined at successive levels in detail and specificity, at each step in the process.

12. The environmental assessment is based on the information collected from primary as well as secondary sources on various environmental attributes. Monitoring of air, water, noise and soil quality was also carried out within the ROW and significant issues were examined during field surveys to determine the magnitude of significant environmental impacts.

13. The major steps in the IEE process for the project were as follows:

1. Collection and Analysis of Data

14. The Baseline data was collected on various environmental components such as soil, meteorology, geology, hydrology, water quality, flora and fauna, habitat, demography, land use, 4

cultural resources, properties and structures. Secondary data on environment for the project corridor were collected both from published and other relevant sources e.g., the Department of Forest, Tamil Nadu State Pollution Control Board, State Statistical Department etc. The data collection from the field was completed with the help of enumerators / investigators. The interviewers were trained for filling up the questionnaire at the site. To ensure the accuracy of the data, data collection was done under the supervision of the ADB TA consultant. The type and source of information compiled in this IEE are shown in Table 2.

2. Environmental Monitoring and Analysis

15. Different locations were identified for monitoring and analysis of the noise level, ambient air and water quality. The monitoring and analysis of water quality, air quality and noise level has been done by M/s Global Lab and Consultancy Services, Salem a leading environmental research laboratory. Air quality monitoring has been carried out as per MOEFCC notification of November 2009 the revised Air Quality standards and the on-site monitoring results are incorporated in Chapter- 4 of this IEE report.

16. Vegetation and Wildlife Surveys: In order to assess presence of flora and fauna along the proposed alignment field surveys have been carried out with the help of field officers of the 5 state forest department and wildlife departments. Specific attention was given to collect the data on presence of Wildlife and birds. Findings are incorporated in Chapter 4 of this IEE report.

3. Analysis of Alternatives

17. Alternative analysis for the present project road alignment has been made on the basis of “with-” and “without project” scenarios. The parameters considered for the analysis are the environmental as well as social features and their likely impact on the natural ecosystem.

4. Stakeholder and Public Consultations

18. Extensive consultations were held during different stages (reconnaissance, detailed design and design review) with key stakeholders that includes local and beneficiary population, government departments/agencies, road users, and project-affected persons. These consultations allowed the interaction between the stakeholders and road designers to identify road features and construction methods that will enhance road upgrading and minimize potential impacts. Information gathered was integrated in the project design and used in formulating mitigation measures and environmental management plan. Detailed description of public consultation is presented in Chapter 7 of this IEE report.

II. POLICY, LEGAL AND ADMINISTRATIVE FRAMEWORK

23. India has well defined institutional and legislative framework. The legislation covers all components of environment viz. air, water, soil, terrestrial and aquatic flora and fauna, natural resources, and sensitive habitats. India is also signatory to various international conventions and protocols. The environmental legislations in India are framed to protect the valued environmental components and comply with its commitment to the international community under above conventions and protocols. Asian Development Bank (ADB) has also defined its Environmental and Social Safeguard policies. This assessment is about the applicability of above laws and regulations, conventions, protocols, and safeguards. This section summaries the following:

• National (India) Environmental Legislation and Legal Administrative Framework, • Social Safeguard Regulatory Requirements, • ADB safeguard policies and categorization of the project, and • Summary of international treaties and applicability to the project

A. National (India) Environmental Policy Framework

24. The legal framework of the country consists of several acts, notifications, rules and regulations to protect environment and wildlife. In 1976, the 42nd Constitutional Amendment created Article 48A and 51A, placing an obligation on every citizen of the country to conserve the environment. The national legislations are broadly divided under following categories:

• Environmental Protection, • Forests Conservation, and • Wild Life Protection.

25. The umbrella legislation under each of above category is highlighted below:

• The Environment (Protection) Act 1986 was enacted with the objective of providing for the protection and improvement of the environment. It empowers the Central Government to establish authorities charged with the mandate of preventing environmental pollution in all its forms and to tackle specific environmental problems that are peculiar to different parts of the country. Various rules are framed under this Act for grant of environmental clearance for any developmental project, resources conservation and waste management. • The Forest Conservation Act 1980 was enacted to help conserve the country's forests. It strictly restricts and regulates the de-reservation of forests or use of forest land for non-forest purposes without the prior approval of Central Government. To this end the Act lays down the pre-requisites for the diversion of forest land for non-forest purposes. • Wildlife (Protection) Act 1972 amended in 2003 was enacted with the objective of effectively protecting the wild life of this country and to control poaching, smuggling and illegal trade in wildlife and its derivatives. It defines rules for the protection of wild life and ecologically important protected areas.

26. State Pollution Control Boards (SPCBs) together form the regulatory and administrative core of the government for managing environmental impacts. Other Ministries/ Statutory Bodies/ Departments responsible for ensuring environmental compliance and granting various 8

clearances includes state ministry /department of environment, regional offices of MOEFCC and state forests/wildlife departments.

27. The environmental impact assessment (EIA) requirement in India is based on the Environment (Protection) Act, 1986, the EIA Notification, 2006 (latest amendment in 2020), all its related circulars, MOEFCC’s Environmental Impact Assessment Guidance Manual for Highways 2010 and IRC Guidelines for Environmental Impacts Assessment (IRC:104-1988) of highway projects. In addition to road widening and rehabilitation including establishment of temporary workshops, construction camps, hotmix plants, and opening of quarries for road construction work require compliance with provisions of The Forest (Conservation) Act 1980 as amended 1988 and Rules 1981 as amended 2003: The Wildlife (Protection) Act, 1972 (amended 1993); The Water (Prevention and Control of Pollution) Act 1972 (amended 1988) and Rules 1974; The Air (Prevention and Control of Pollution) Act, 1981 (amended 1987) and Rules 1982; The Noise Pollution (Regulation and Control) Rules, 2000 (amended 2002) and the Hazardous Waste (Management, Handling and Trans-boundary Movement) Rules 2008 (amended 2009).

28. A review is undertaken for all the environmental rules and regulation which might be applicable to the proposed road corridor improvement activities. Legislations applicable to this project are summarized below in Table 3. There is no separate state level legislation. However, various acts like Water and Air are enforced through state level authority, the State Pollution Control Board (SPCB).

29. Specifically for the proposed Kumbakonam - Sirkazhi (SH-64) in the state of Tamil Nadu, the following environmental laws and regulations applicable are in Table 3:

30. In addition to the acts and regulations listed above the Environmental Impact Assessment Guidance Manual for Highways 2010 issued by MOEFCC and the IRC Guidelines for Environmental Impacts Assessment (IRC:104-1988) of highway projects issued by MORTH, were referred in the process of preparing this IEE. The following requirements are particularly important and need special attention in order to avoid any delays for a project:

• As per provisions of the EIA Notification 2006 (amended in 2009, 2011 and 2013), all new state highway and state highway expansion projects except in hilly terrain (above 1,000m AMSL) and or notified ecologically sensitive areas (ESA) fall under category B and does not require environmental clearance from the State Environmental Impact Assessment Authority (SEIAA). Since the proposed project involve expansion of the existing state highway road section between Kumbakonam to Sarkazhi and this section is not located in hilly terrain (above 1,000m AMSL) or any notified ecologically sensitive areas, it does not fall under the 10

purview of EIA notification.1 Therefore an environmental clearance from SEIAA is not required for this project road. • . Proposed Kumbakonam to Sarkazhi road does not pass through forest areas, therefore forest clearance is not required as per Government of India requirements. • As per the Wildlife Protection Act, clearance from National Board for Wildlife (NBWL) is not required for proposed Kumbakonam to Sarkazhi road project as the project road not located within core or notified buffer zone boundary of any protected area.

• Cutting of trees in non-forest land requires a tree cutting permit from the local forestry department. All trees cut under a project must be compensated by compensatory afforestation as required by the Forest Department. • As per Office Memorandum (OM) issued by MOEFCC on 19 March 2013 the grant of environmental clearance for linear projects including roads has been delinked from the forestry clearance procedure. Hence, after receipt of environmental clearance construction works may commence on sections/parts of a linear project that do not require forestry clearance. Construction works may commence on sections requiring forestry clearance only after receipt of the respective clearance. • Placement of hot-mix plants, borrow areas, quarrying and crushers, batch mixing plants, discharge of sewage from construction camps requires No Objection Certificate (Consent to Establish and Consent to Operate) from SPCB prior to establishment (Table 3, construction stage item 1 and 2). • Permission from Central Ground Water Authority is required for extracting ground water for construction purposes, from areas declared as critical or semi critical from ground water potential prospective by them (Table 3, construction stage item 6). • Before the start of civil works for the any component of the project the project proponent (TNHD) must obtain necessary clearances / permits from the regional office of the Ministry of Environment and Forest and Climate Change and State Pollution Control Board.

B. Social Regulatory Requirements of India and Tamil Nadu

31. There are many rules and regulations framed by the Government of India for the protection of workers. Most of these legislations will be applicable to contractors in charge of construction. EA will ensure compliance to these social legislations through contractual obligation and regular checks and penalties. These legislations include The Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act, 1996; Child Labour (prohibition and Regulation) Act, 1986; Minimum Wages Act, 1948; Workmen Compensation Act, 1923; Payment of Gratuity Act, 1972; Employee State Insurance Act; Employees P.F. and Miscellaneous Provision Act, 1952; Maternity Benefit Act, 1951; Payment of Wages Act, 1936; Equal Remuneration Act, 1979; Inter-State Migrant Workmen’s (Regulation of Employment & Conditions of Service) Act, 1979; Equal Remuneration Act, 1979 etc.

1 Ecologically Sensitive Areas (ESA) are areas notified by MoEFCC an ecologically fragile area under EPA rules, 1986. List of notified ESA in India are available at http://moef.gov.in/rules-and-regulations/esa-notifications/. While Eco-sensitive Zone (ESZ) is area around the notified Protected Areas (National Parks and Wildlife Sanctuaries) as per the Guidelines for Deceleration of ESZ around National Parks and Wildlife Sanctuaries, as details are given at http://moef.gov.in/rules-and-regulations/esz-notifications-2/. 11

C. International Treaties and Relevance to the Project

32. Government of India has signed many international treaties. GOI has also framed various laws, regulations and guidelines to meet country’s obligations under these treaties. Projects of this magnitude may contribute in meeting country’s obligation directly or indirectly. A screening was carried out of these treaties regarding its applicability to this project. The relevant international treaties are:

• Kyoto Protocol to the United Nations Framework Convention on Climate Change (Rectified by India in 1997): The Kyoto Protocol is an international agreement linked to the United Nations Framework Convention on Climate Change. The major feature of the Kyoto Protocol is that it sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas (GHG) emissions. These amount to an average of five per cent against 1990 levels over the five-year period 2008-2012. • The Paris Agreement 2015: The Paris Agreement is an international agreement by 196 parties which aims at limiting global warming to 1.5 to 2 degrees C above pre-industrial levels. Through this, the parties also agreed to a long-term goal for adaptation through nationally determined contributions (NDCs), which is requested to be submitted every 5 years. India submitted its first NDC on October 2, 2016. • Convention Concerning the Protection of the World Cultural and Natural Heritage (Rectified by India in 1972): The most significant feature of the 1972 World Heritage Convention is that it links together in a single document the concepts of nature conservation and the preservation of cultural properties. The Convention recognizes the way in which people interact with nature, and the fundamental need to preserve the balance between the two. • Convention on International Trade in Endangered Species of Wild Fauna and Flora (Washington, 1973): Seek to avoid poaching by construction workers especially in environmentally sensitive areas. • Convention on Migratory Species of Wild Animals (Bonn, 1979): Ensure potential impacts on any migratory species supported by the project area of influence assessed and managed. • Convention Relative to the Preservation of Fauna and Flora in the Natural State (1933): Preservation of Flora and Fauna.

D. Project Standards

33. Environmental standards for air, water, soil, noise, and vibration, among others will follow applicable CPCB, World Bank Group (WBG)/International Finance Corporation (IFC) Environment Health and Safety (EHS), or State-imposed limits, whichever is most stringent. When national regulations differ from the performance levels and measures presented in EHS Guidelines, projects are expected to achieve whichever is more stringent. If less stringent measures are appropriate in view of specific project circumstances, full and detailed justification of the applied standard or guideline should be presented in the environmental assessment. The justification should demonstrate that the chosen alternative’s performance level is protective of human health and the environment. CPCB and IFC EHS guidelines are provided in Appendices.

E. ADB’s Safeguard Policy Statement Requirements

34. ADB has defined its Safeguard requirements under its ‘Safeguard Policy Statement 2009 (SPS 2009). The prime objectives of safeguard policy are to: (i) avoid adverse impacts of projects on the environment and affected people, where possible; and (ii) minimize, mitigate, and/or compensate for adverse project impacts on the environment and affected people when avoidance is not possible. This policy requires assessment, mitigation and commitment towards environmental protection. The extent of assessment depends on the category of the project. ADB’s SPS 2009 classifies a project depending on following three categories.

• Category A: A proposed project is classified as category A if it is likely to have significant adverse environmental impacts that are irreversible, diverse, or unprecedented. These impacts may affect an area larger than the sites or facilities subject to physical works. An environmental impact assessment is required. • Category B: A proposed project is classified as category B if its potential adverse environmental impacts are less adverse than those of category A projects. These impacts are site-specific, none or very few of them are irreversible, and in most cases mitigation measures can be designed more readily than for category A projects. An initial environmental examination is required. • Category C: A proposed project is classified as category C if it is likely to have minimal or no adverse environmental impacts. No environmental assessment is required although environmental implications need to be reviewed.

F. Category of the Project

35. The project has been evaluated considering the outcome of the ADB Rapid Environmental Assessment (REA) checklist and the same is enclosed as Appendix 1. All environmentally sensitive areas along the proposed alignment have been critically analyzed to assess the magnitude and extent of likely impacts.The project road do not falls within core/buffer zone of any protected area

36. Certain sections of the project road involve expansion of the existing road to two lane standard road, where there will be substantial land use change and earthworks involved. The road section crosses some of the water bodies and acquisition of land may be involved at a few stretches.

37. The project section is not located near to any notified protected area and there are no wildlife has been reported due to residential habitation development along the road. There are no potential significant ecological impacts anticipated from project during construction and operation stage. Hence, the project falls under environment category B as per ADB Safeguard Policy Statement 2009.

III. PROJECT DESCRIPTION

A. Type and Location of Project Road

38. This report on Initial Environmental Examination (IEE) deals with the environmental analysis of the project road considered under ADB supported TNICP - Upgrading Kumbakonam - Sirkazhi. It starts from Km 2+875 near Kumbakonam (latitude 10°58'14.401"N, longitude 79°24'3.478"E) to Sirkazhi bypass junction at km 51+577 (latitude 11°13'6.823"N, longitude 79°44'10.91"E). The existing length of the project road is 37.336 km.

39. The project road is situated in Thanjavur and Mayiladuthurai districts of Tamil Nadu. One bypass has been planned in the project road for Vaitheeswaran kovil. Few realignments have also been proposed for geometrics improvements. Project activities includes resurfacing, widening, restoration and rehabilitation. It will involve improvement in project road taking into consideration of lane configuration, widening scheme, speed, embankment height and the urban or rural setting of the road. The project is linear in nature.

B. Features of the Project Road

41. The project road traverses in plain terrain passing through rural areas as well as few intermittent semi-urban and urban settlements intermittently. In rural areas the land use on both sides is agricultural land/open spaces interspersed with small structures. The abutting land use in the built-up areas is predominantly residential and commercial. Few educational institutions and religious structures exist along the project road in some of the villages and town sections. It is observed that the vertical alignment of the road is quite flat except at few culvert locations.

42. Traffic signs are missing at many locations along the project road. No warning signs exist before the approach of the junction and approach of curves. Directional signs exist at few locations.

B.1 Right of Way (RoW)

43. The existing right of way (RoW) of the project road section varies between 8to 30m, however the carriageway/roadway width of the road is uniform between 5.5m to 7m with 0.3m- 0.5m earthen shoulder. The existing carriageway of project road is two lanes in most portions, however, in builtup sections existing carriageway is of intermediate lane configuration. The total length of road in intermittent builtup sections is about 22.174 km.

B.2 Cross Drainage Structures

44. There are no existing major bridges, 7 minor bridges and 47 culverts falling along the alignment. 18 are pipe culverts, 28 are slab culverts and 01is box culvert. There is no sufficient drainage system available along the project road.

C. Engineering Surveys and Investigations

48. Following surveys and investigations had been carried out on the project road for collection of data for incorporation in the DPR and evolve the design for improvement and upgradation:

topographic surveys; traffic surveys; • road and pavement condition survey and inventory; • culverts and bridges condition survey and inventories; • material surveys; • hydrology studies for new bridge structures; • • 17

geotechnical investigations & subsoil exploration for structures; and existing utilities surveys. • D. • Design Standards

49. This section describes the design standards and principles based on which the various designs have been carried out. The formulation of the design standards is required in order to avoid any inconsistency in design from one section to the other and to provide a desired level of service and safety. These proposed standards are consistent with the parameters recommended in the relevant standards of the Indian Roads Congress (IRC). The relevant IRC/ MORT&H design standards adopted for the Engineering Design are given below.

• Manual of Specifications and Standards for Two Laning of State Highways: IRC SP 73– 2015 • Ministry of Road Transport & Highways (MoRTH) specifications and circulars – Fifth edition.

1. Geometric Design

50. While doing the geometric design, the following have been taken into consideration:

• The designed facility shall not become obsolescent before the design year. • Design shall be consistent and the standards followed for different elements shall be compatible with one another. • The design shall cover all geometric aspects of road including road, safety features, road furniture, signages, grade separated structures, etc. • The design will be done aiming at minimizing the vehicle operating cost including initial cost, cost of maintenance etc. • The design will take into consideration the environmental, aesthetic and landscaping aspects of the project road.

2. Geometric Design Control

51. The detailed design for geometric elements covered, but were not limited to the following major aspects:

• Horizontal alignment • Longitudinal profile or vertical alignment • Cross-sectional elements • Junctions, intersections and interchanges

52. The detailed analysis of traffic flow and level of service for the existing road has been made and traffic flow capacity for the project road was worked out. This analysis establishes the widening requirements with respect to the different horizon period.

53. Different options for providing grade separated interchanges and at grade intersections have been examined and the geometric design of interchanges has taken into account the site conditions, turning movement characteristics, level of service, overall economy and operational safety.

3. Horizontal Alignment

a. Design Speed

54. Design speed is the basic parameter, which determines the geometric features of the road. The proposed design speeds for state highway Roads in different terrain categories as per IRC-73-1980 were adopted.

55. The project road located in plain terrain improved to provide minimum radius in most of the locations of curves to attain better alignment for the design and operational speed of 65kmph to 80kmph except at built up location. The only physical hindrance in the existing road corridor was from the road side settlements and facilities scattered all along the road. The road is designed in accordance with agreed design standards depending on the type of terrain and the land-use. Further reductions in the design and operational speed along sensitive land uses may be adopted to reduce noise and for pedestrian safety.

b. Radii of Curve

56. The geometry of the road is corrected to have the horizontal geometry correspond well with the IRC standards. At the locations where the existing geometry is not in accordance with the design standards, an attempt has been made to regularize it. The minimum radii of the curve corresponding to the design speed have been applied as per IRC stipulations.

57. The minimum radius of horizontal curves is calculated from the following formula:

R = V2 / 127 (e+f) Where, V = vehicle speed in Kmph e = Super elevation in % f = Co-efficient of friction between vehicle tyre and pavement (taken as 0.15) R = radius in metres

58. Adopting a maximum value of 7% for super elevation, the minimum radius for horizontal curves works out to be per Table 7 as per IRC: 38/IRC SP-48.It is required to provide the desirable radius on the curves.

Table 7: Radius for Horizontal Curves Terrain Radius of horizontal curves (m) Categories Desirable Minimum Plain 400 255 Rolling 255 170 Mountainous 100 65

c. Super-elevation

59. The super elevation at curves have been arrived at as per the following equation:

e=V2/225R where: 19

V - Vehicle speed in m/sec. e - Super elevation ratio in meter per meter R - Radius in meters.

60. The super elevation has been calculated keeping in view the horizontal radii and gradient at curves at different locations and maximum super-elevation is restricted to 7%.

d. Curves without Super Elevation

61. When the value of super elevation obtained from the parameters stated above is less than the road camber, the normal cambered sections are continued on the curve portion, without providing any super elevation. Normal camber of 3% is provided for flexible pavement.

e. Transition Curves

62. Transition curves are necessary for vehicle to progress smoothly from a straight section into a circular curve or between curves of different radius. The transition curve also facilitates a gradual application of the super elevation and any widening of the carriageway that may be required for the horizontal curves. The minimum length of the transition curve is determined from the following two considerations:

a. As per Comfort criteria, Ls = 0.0215 V3 / CR Where, Ls = length of transition in metres V = Speed in kmph R = radius of circular curve in metres C = 80/ (75+V) (subject to maximum of 0.8 and minimum of 0.5)

b. As per rate of change of Super-elevation,

63. The rate of change of super elevation cannot be steeper than 1 in 150. The formula for minimum length of transitions depending on the terrain (plain/rolling) is:

Ls = 2.7 V2 / R

f. Sight Distance

64. Intermediate sight distances have been adopted for the highway design as per the requirements of 2lanemanual provision. In general Intermediate Sight distance is adopted for the 2 lane sections but at locations where minimum intermediate sight distance cannot be followed safe stopping sight distance has been adopted.

4. Vertical Alignment

a. Gradients

65. The vertical alignment of the carriageway has generally been compatible with the guidelines given in the IRC SP 23 and the maximum gradient at all structure approaches is restricted to 2%.

• At locations of grade break of 0.5%, vertical curves have been provided. • The length of vertical curve is restricted to minimum 50m • Number of PVI are not be more than 4 in one km. • At locations of sight deficiency, at least Stopping Sight Distance (SSD) are provided.

66. Safe stopping sight distance, both in the vertical and horizontal directions are applied in design where ever possible. The sight distance values as per IRC recommendations are given in Table 8.

Table 8: Sight Distance Design Speed (km/h) Safe stopping sight distance (m) 80 120 65 90 50 60 40 45

5. Pavement Design

67. The entire road stretch is proposed as per the guidelines comprise of Flexible Pavement. Design is primary in accordance with IRC guidelines. The recommendation given in IRC- 37:2012, or equivalent method are used for new carriageway and paved shoulders. The pavement are designed for a service life of 20years. Strengthening of the pavement by bituminous overlay are done periodically after 10 years.

68. Thickness requirements for the flexible pavement has been established based on IRC: 81:1997.

6. Embankments

69. Width: The width of the embankment is as per the approved typical cross-sections.

70. Height: The height of the embankment is as per the final road levels.

71. Slope Protection: Embankments is protected with stone pitching as per “IRC 75-2015; Guidelines for Design of High Embankments”.

7. Grade Intersections

72. The locations where at grade junctions are required, the designs have been done as per the Guidelines given in MoRTH and on the basis of “IRC SP: 41-1994, Guidelines for the Design of At-grade Intersections in Rural and Urban Areas.”

8. Bus Stops

73. The bus bays where provided in accordance with guidelines specified in “IRC: 80-1981, Type Designs for Pick-up Bus Stops on Rural (i.e. Non-Urban) Highways”. The bus stop layout has been provided for safe entry and exit of buses and safe movement of passengers. Bus stops with passenger shelter are proposed at suitable selected locations.

9. Truck Parking Areas

74. The proposed layout and the locations of truck lay-by are generally based on the provisions of 2 lane manual; if required.

10. Traffic Safety Features, Road Furniture, Road Markings and Other Facilities

75. Traffic signs are missing at many locations on the project road. No warning signs exist before the junction and curves. Directional signs exist only at a few locations. These missing safety features will be the part of the proposed improvements. High Intensity Micro-Prismatic Grade sheeting (HIP) (Type IV) shall be provided.

76. Traffic signs: The traffic signs are divided into three broad categories as warning signs, regulatory signs and information signs. Warning sign plays a crucial role in terms of road safety and for advance information about hazards ahead. Typical examples of warning signs are curve ahead, pedestrian crossings, gap in median etc. Regulatory/ Mandatory signs regulate the side of road or through traffic in order to have a safe movement. STOP, speed limit, NO parking and rest areas etc. are some of the regulatory traffic signs. Information signs are provided to give information and guidance about the facilities available to the road users. Village sign boards, fuel stations, hospitals etc are some of the information sign boards.

77. All critical locations are identified at the proposed geometric improvements along the project road and cross roads where Warning, Regulatory and Information signs are required. Traffic signs have been designed to convey clear and unambiguous messages to road users so that they can understand quickly and easily. IRC-67:1977, code for practice of road sign, has been followed for finalization of sign installation. On unkerbed roads segments, the extreme edge of the sign would be 2 to 3 m from the edge of the carriageway. On kerbed road it is proposed as not less than 60 cm away from the edge of the kerb.

78. Road Markings: Road markings play a very important role in guiding the driver and providing the information necessary to negotiate conflict points on the road network. It is given a high priority to improve the safety. IRC-35: 1997, Code of Practice for Road Markings, provides the recommended practice for use of road markings. Road markings are lines, words and symbols attached to the carriageway or adjacent to the carriageway for controlling, warning, guiding and informing the users. Yellow, white and black colours are the standard colours used for marking. Road marking are classified as longitudinal marking, marking at intersections, marking at hazardous locations, marking for parking and word messages. Thermoplastic road markings have been proposed considering their long lasting effect.

79. Delineators: The delineators are effective on dangerous bends, on approaches to intersections and on embankments. Though all horizontal curves are designed to the IRC standards, delineators have been proposed for additional guidance and information to the commuter at curves (Radius less than 1000m). Locations along the high embankment have also been provided with delineators. Delineators with reflectorized panels have been considered.

80. Road lighting: Night-time accidents in urban areas can be substantially reduced by the implementation of adequate street lighting. The stretches of the project road traversing through the built-up/urban areas are proposed with adequate lighting. Road lighting has also been proposed at all major junctions. One/ Two/ Three arm bracket Sodium vapour lamps have been considered.

81. Crash Barrier: In addition to the adequate provisions of roadway width and roadside design, crash barrier/guard rails have been proposed along the roadway edge on either side based on the sections of the road:

82. For the embankments up to 3 m height, reasonably flatter side slope of 1 vertical: 3 horizontal or more would enable erring vehicles to return to the traffic stream.

83. Roadside Facilities: The roadside facilities are provided as per the requirement of road users. Bus lay-by with bus shelters, High mast Light, Street Lights, Road Furniture’s, Delineators, Road Studs, etc., are proposed for project road of SH-64.

84. Bus lay-by and shelters: Consultants have identified the location/site for the proposed bus lay bye for each village or built-up locations based on the following criteria:

85. Bus shelters are proposed near to settlement areas to minimize the walking distance and major intersection/junction should have direct pedestrian links segregated from motorized traffic. It should be positioned in straight and level sections of road and should be visible from a long distance from both the directions.

86. For safety and operational reasons suitable safety features, road furniture and other facilities along the project road have been provided. These features included safety barriers, road signs, road markings, road lighting, route markers, kilometre and hectometre stones, road delineators, ROW pillars, parking areas and rest areas, bus stops/bays, and landscaping. Wherever possible these features are provided in accordance with relevant IRC or another standard, as detailed below. If no IRC Codes or the MoRTH Specifications are available, international standards such as BIS / AASHTO / ASTM / British Standards have been used in detailed design.

87. Road Humps: Road humps or speed breakers are formed by providing a rounded hump of 3.7 m width (17 m radius) and 100 mm height for the preferred advisory crossing speed of 25 kmph for general traffic as per the IRC: 99–1988. The basic material for construction is bituminous concrete formed to required shape. Road humps have been proposed on minor roads at junctions /intersections with major roads, school and hospital zones. Proper signboards and markings are provided to advise the drivers in advance of the situation. Road humps are extended across carriageway up to the edge of paved shoulder.

88. Rumble Strips: Rumble Strips are formed by a sequence of transverse strips laid across a carriageway with maximum permitted height of 20 mm. These rumble devices produce audible and vibratory effects to alert drivers to take greater care and do not normally reduce traffic speeds in themselves. The typical design details of rumble strips proposed are transverse strips of Pre-mix bituminous concrete 500 mm wide and overall thickness 20 mm laid across a carriageway up to the end of paved shoulder. There will be 6 such transverse strips spaced at 0.5 m c/c. Proper signboards and marking are proposed to caution the drivers in advance of the situation. Rumble strips are proposed.

a. Sharp curves with radius less than 170m. b. Transition zones (speed limit zones). c. Village/built-up approaches. d. Sensitive receptors (schools and hospitals)

89. Landscaping and Tree Plantation: Tree plantation have been provided in accordance with “IRC SP: 21- 2009, Guidelines on Landscaping and Tree Plantation” and Set back distance of trees in different situations is as per “IRC: 66-1976, Recommended Practice for Sight Distance on Rural Highways”.

Minor realignments are proposed along the existing alignment from km 13+600 to km 13+900, from km 41+660 to km 42+330, Km 43+330 to Km 43+550 and from km 45+300 to km 45+558. There is a need for land acquisition for road widening and at the location of realignments. The total land acquisition for the project road improvement has been estimated as 18.0182 Hectares.

6. Culverts and Bridges

97. As per the inventory, there is no major, seven minor bridges, and 47 Culverts (18 Pipe, 28 slab and 1 Box) on the existing project road. Based on the inventory& condition survey of structures, latest circulars of MoRT&H & IRC circulars / codal provisions and keeping in view of the ToR, 5 minor bridges are retained, 1 is proposed for widening and. Three new minor bridges are proposed (Km 43+814, km 47+700 and km 48+928) and One Major Bridge Proposed at Km 13+739 along the Project Road.19 pipe culverts will be proposed as box culverts, 27 slab culverts will be reconstructed to box culverts. 1 existing box culvert is retained and widened.. 35 new box culverts are proposed(19 along existing SH64 and 16 along the proposed bypass).

7. Borrow and Quarry Materials Sourcing

98. About 128400 cum of borrow earth, 2,35,000 cum of aggregates is estimated to be required for the constructional activities of road section. The information about existing stone Quarries, Morum Quarries/ Borrow pits, Sand Quarries was collected from local PWD Divisional Offices and Sub divisional Offices, local construction contractors and local material suppliers throughout the project area, from other sources and from direct observation and by site visits. Location maps and type of material available in each project road were also collected and produced. The suitability of the materials sources is evaluated based on laboratory testing. After analyzing the suitability of those material sources quantitatively and qualitatively, the lead chart is prepared. The Locations of borrow area for the project road has been shown in Appendix 2. 31

8. Geometric Design

99. All the geometric design element proposed in this project is carried out as per the design standards stipulated in IRC code provisions. Comprehensive design standards have been utilized linking individual design elements to best estimates of actual speed. The emphasis has been given on maintaining continuity or giving adequate warning where it could not be made. The realignment locations identified to improve the horizontal geometrics of the project road.

100. Plan and profile has been designed keeping in view the considerations such as design speed appropriate for the terrain and site constraints. The FRL given in the profile shall be followed as a minimum. However, the Contractor shall improve upon the plan and profile to the extent possible within the site (proposed ROW) with prior approval of CSC.

101. Except in the following curve locations the design and operational speed all along the project road is designed as 65kmph to 80 kmph.

10. Water for Construction

103. The water requirement has been assumed based on past project experience and on the strict quality control basis. A domestic requirement of 150 liters per worker for each day has been assumed. For this project about 200 resident workers have been considered. A volume of 450 KLD (30 KLD domestic water demand and average 400 KLD water required for construction activities) during the construction phase will be taken from surface water bodies or withdrawn ground water after obtaining necessary permissions, in such a manner that the local water supply is not affected. The water withdrawal will not be from the single location as the project is linear in nature. No water will be sourced from local public utility for road construction.

F. Construction Camps

104. One construction camp will be set up by the contractor at a suitable location along the project corridor which will be in consultation with the Project Director and Tamil Nadu State Pollution Control Board. The camp will be setup away from the settlements, in the downwind direction. The guidelines for siting & layout of construction camp is given in Appendix-9.

IV. DESCRIPTION OF THE ENVIRONMENT

A. Introduction

108. In order to assess the impacts of the proposed improvement to the project road, field visits were undertaken to understand environmental profile of the project influence area. This involved field inspections at all the sensitive locations, collection of secondary information for all the environmental components and discussions with the officials, NGO’s and local populace. The profile presented below comprises of the following:

• Physical environmental components such as meteorology, geology, topography, soil characteristics, ambient air quality, surface and sub-surface water quality; • Biological environmental components such as aquatic life, avian and terrestrial fauna, vegetation and other flora, fauna and mammals, and • Land environment in terms of land use, soil composition.

109. The data on water, soil, air and noise were collected through field monitoring. The environmental monitoring was carried out by NABL accredited laboratory “Global Lab and Consultancy Service Pvt. Ltd.”, Salem in the month of November- December 2019 for baseline air, noise, vibration, water and soil parameters. Climatological data was collected from India Meteorological Department (IMD). Efforts have been made to compile the available data from literature, books, maps and reports. The methodology adopted for data collection is highlighted wherever necessary. Environmental attributes and frequency of baseline surveys are presented in Table-10. The environment parameters monitoring locations are shown in Figure 3. The baseline parameters are selected as specified by regulatory agencies in India and number and locations of the sampling are selected with due consideration to environmental sensitivity along the project line alignment and as agreed upon with the client.

B. Physical Environment

110. Information of various physical parameters was collected from the Indian Meteorological Department (IMD), Statistical Department, Gazetteer of Tamil Nadu, Forest Department, Department of Environment and other concerned government departments and discussions with the officials from these agencies. 36

1. Meteorological Conditions

111. Meteorology plays an important role in transport, diffusion and dispersion of pollutants in the atmosphere. Due to this reason meteorological data has been collected from the field in the month of November- December 2019 as well as secondary data has taken from the IMD website.

112. Among all other physical factors, climate is the most important factor-influencing environment because it plays a vital role in determining the evolution of landforms (erosion, soil characteristics), types of flora and fauna (ecological diversity), the productivity of ecosystems. It also has an influence on the pollution loads on the environment.

113. The climate of Tamil Nadu state is tropical, with distinct wet and dry seasons. According to agro-ecological classification, the state has hot and semi-arid climate. The climate may be classified into four distinct seasons: winter (January–February), summer (March–May), southwest monsoon (June–September) and northeast monsoon (October–December).

114. The various climatic factors such as temperature, humidity and rainfall pattern in the project area have been discussed in detail in the following sections.

a. Rainfall

115. The Nagapattinam is the nearest available metrological station for Kumbakonam – Sirkazhi Road Section of SH-64. The climate of Nagapattinam is tropical in nature. The summer season starts in the end of March and remains till the advent of monsoons in early June.

116. The rainy season starts with the pre-monsoon showers towards the end of May and the Southwest and Northeast monsoons arrive in June. It rains very heavily during monsoons. The average annual rainfall is around 1500mm. Nagapattinam experiences a lot of cyclones and counter cyclones during the monsoon. The season also witnesses some minor Tsunamis. A major one hit Nagapattinam in the year 2005 that left the city completely devastated. Rainfall distribution map of Tamil Nadu is shown in Figure 4.

117. From the above map it is clear that project road lies in areas having high rainfall distribution. The monthly average rainfall in project districts is presented in table 11. It the clear from the table that the average rainfall in Thanjavur is about 888.78mm while the average rainfall in Nagapattinam is 1306.6mm. The Nagapattinam district receives more rainfall than Thanjavur district. However,rainfall was not observed during the field monitoring carried out in the months of November-December 2019.

b. Temperature

118. Nagapattinam: The climate of Nagapattinam is tropical in nature. The summer season starts in the end of March and remains till the advent of monsoons in early June. The average maximum temperature during the summers remains around 35°C. The winters are relatively very pleasant when average minimum temperature remains around 20°C.

119. Thanjavur: The temperatures are highest on average in May, at around 31.6 °C. At 25.2°C on average, January is the coldest month of the year. The mean maximum temperature of the district shows variation between 36.6° in May and 26.7°C. The mean minimum temperature shows variation from 28.7° C to 21.7°C in December.

120. The minimum temperature recorded during the study period along the project road were 21.2ºC. The maximum temperature recorded was 30.2ºC. The overall average ambient temperature during the period was 26.4ºC. Temperature distribution map of Tamil Nadu is shown in figure 5, as project are falls in strong hyperthermic region of the State. 38

Project Road

c. Winds

122. Wind speed and wind direction have a significant role on the dispersion of atmospheric pollutants and therefore, the air quality of the area. Ground level concentrations for the pollutants are inversely proportional to the wind speed in the down wind direction, while in upwind direction no effect will be observed and in cross wind direction partial effect due to the emission sources is observed.

123. The minimum wind speed recorded during the study period along the project road were 2kmph. The maximum wind speed recorded was 8kmph. The overall average ambient wind speed during the period was 3.3kmph. The dominating wind direction observed along the alignment during field monitoring was NE(North-East) followed by SW(South-West).The details of other meteorological parameters observed along the road section during the baseline environmental monitoring is given in Appendix 3.

d. Climate Risks and Vulnerability

124. A detailed climate risk and vulnerability assessment has been prepared for the project in compliance with ADB requirements. The assessment revealed that the project has high overall risk for flooding due to extreme rainfall, storm surges, and other extreme events such as water scarcity and heat waves. Measures to address these have been included in the design which include increased drainage capacity and embankment heights2.

2. Topography

125. The project road falls in Mayiladuthurai, and Thanjavur districts of Tamil Nadu. Mayiladuthurai district has been recently bifurcated into Mayiladuthurai. This project road falls in Mayiladuthurai District also. The geography and topography of these districts and project road is discussed below.

126. The present geomorphic set up in Nagapattinam district is the result of action of the major rivers with their distinct tributaries, oscillations in the sea level, tidal effects of Bay of Bengal and forces of wind. The landforms are delineated under erosion and depositional regime. The depositional regime comprises of a coastal plain under marine influence, a flood plain of fluvial regime with an intermixing section of both fluvial and marine influence. The entire area is a plain terrain with a gentle slope towards east and southeast. The maximum elevation is about 21 m above mean sea level in the west.

127. Different geomorphic units like flood plain, delta plains, natural levees and sedimentary high ground are noticed in Thanjavur district. Sedimentary high ground ranging in elevation between 60m and 80 m amsl found in southern side of Thanjavur town mainly constitute laterites. Area north of Thanjavur had been fully covered by flood plains. Isolated levee complexes are found parallel to the Vennar river course.

128. The topography (altitude) map for the State of Tamil Nadu is presented in Figure 7 wherein project road is also marked. As can be inferred from the map, the project region has plain topography having an altitude in the range of 1-150m AMSL. The project road traverses in plain terrain passing through rural areas as well as many intermittent semi-urban and urban

3. Geology and Mineralogy

129. Geologically, the entire state can be broadly classified into hard rock or crystalline formation and sedimentary formations. Nearly 73% of the state is underlain by crystalline rocks of Archean metamorphic complex comprising of granite, charnockites, gneisses, chists etc. They are further intruded at many places by quartz veins, pegmatites and other ultra-basics like dolomites. The sedimentary rocks occur along the coast, flanking the crystalline mass in the west. This sedimentary formation mainly comprises of recent alluvial deposits, tertiary sandstone, lignite, cretaceous limestone, argillaceous sandstone etc. Besides these, sporadic occurrences of upper Gondwana formations consisting of compact sandstone, shale etc, are found as thin and isolated patches. Younger alluvial deltaic deposits cover the entire coastal belt: The geological map of Tamil Nadu state is shown in Figure 9.

130. Tamil Nadu is the leading holder of India's resources of vermiculite, magnetite, dunite, rutile, garnet, molybdenum and limonite. The State accounts for 81% lignite, 75% vermiculite, 69% dunite, 59% garnet, 52% molybdenum and 30% titanium mineral resources of the country. The geology and mineralogy of the project districts and the project districts are as follow.

131. Nagapattinam District: The important major minerals found in this district are Crude oil, Natural gas, Silica sand, Lime shell and Heavy Mineral Sand (Garnet, Iluminite, Rutile Zircon, Monozite). In Nagapattinam district, minor minerals such as sand and brick earth quarries are available. There are 8 sand quarries operating in this district in Kollidam River, Thirumalairajan River and Vettar areas.

132. The Heavy Mineral sands comprising on assemblage of minerals of higher specific gravity are occur as Placer deposit along the Sea Coast in the beach sand. It occurs in Tharangamapdi and Sirkali Taluks in Nagapattinam District. Garnet is used in the abrasive industries, and manufacturing synthetic gems. Illuminate is used for aircraft industry. Zircon is used for manufacturing Zirconium Crucibles. The silliminate is used for Aluminum industries.

133. Thanjavur district: Important minerals that are found to occur in the Thanjavur districts are garnet and lignite deposits. Predominant geological formations in the district are recent alluvium, Padakkudi, Orthanadu formations and Eastern ghat weathered and fractured gneissic rocks.

134. No mining activities were seen near the project road. 42

4. Soil Characteristics

135. In Tamil Nadu soils are classified into six orders, 12 sub-orders, 20 great groups, 44 subgroups and 94 soil families in the hierarchy. The six orders are Entisols, Inceptisols, Alfisols, Mollisols, Ultisols, Vertisols. Inceptisols cover about 50% of the State’s total geographical area followed by Alfisols (30%), Vertisols (7%), Entisols (6%), Ultisols (1%) and negligible area by Mollisols. About 5% of the areas are miscellaneous land types, which includes rocklands, marshes, urban areas and water bodies.

136. Nagapattinam District: The entire Nagapattinam district is covered by semi- consolidated formations consisting of sand, silt and clays. The major part of the district is covered by black clay and isolated patches of brown clay loam in the area bordering the NE boundary of Karaikal Region are seen. Some patches of Arenacious soils are also found along the coastal line. 43

137. Thanjavur District: The Thanjavur district is occupied by different geological formations. The different types of soil are derived from the formations are;

• Quaternary: Sand, silt and clay super imposed sand, natural levee complexes • Pliocene: Clays heavily weathered super imposed old drainage morphology • Miocene: Sands, clay bound clays gravels • Cretaceous: Reddish and yellowish calcareous sand stones, clays and lime stones

138. Based on water retention characteristics, a portion of project region have soils that have very high water retention characteristic as shown in Figure 10. The soil order and soil texture map of Tamil Nadu are given in Figures 11.

Figure 10: Soil Type based on Water Retention Characteristics for Tamil Nadu

Project Road

139. Soil samples were collected at 4 locations from agriculture fields (km 5+000, km 22+200, km 43+100 and km 53+000) in Kumbakonam-Sirkazhi road section of SH64 during DPR preparation. These soil samples were analysed for physical characteristics (colour, texture, water retention capacity, infiltration rate and density), particle size distribution, chemical characteristics (pH, electrical conductivity and organic carbon), and nutrient contents (NPK). The soil monitoring locations are given in Figure 3.The results of the soil sample analysis for the project roads are given in Table 12.

140. The pH levels of the soil samples show that soil is neutral at all locations along the road section alignment. The soil type is clay and loamy clay in texture. The nutrient status of soil is also a key element in agriculture. Above results also shows that the soils of the study area have good amount of primary nutrients i.e., nitrogen (N), phosphorus (P) and potassium (K) content. From the results it can be observed that the soil in the project area is fertile with high agricultural productivity with appropriate use of fertilizer. The soil has good electrical conductivity.

5. Seismicity and Volcanic Activity

141. The State of Tamil Nadu is a zone of low to moderate seismic activity with a sparse historical record of significant earthquakes. Seismicity / Effect due to earthquake have been accounted for by considering the seismic load in longitudinal and transverse direction. For the purpose of determining the seismic forces the country is divided into four zones (Zone II to Zone V) based on the intensity of earthquakes that a particular area may be subjected to, with Zone V comprising of areas which have been subjected to severe earthquakes & Zone-II comprising areas least liable to earthquakes. The seismic loads are calculated using Response Spectrum method as per Modified clause of IRC 6: 2010. The seismic force depends upon several factors like zone factor, Period of vibration, Soil type etc. The whole project area falls in the vast volcanic basalt beds of Deccan plate, which formed towards the end of Cretaceous period, between 65 and 67 million years ago. There is no recent seismic and volcanic activity reported along the project area.

142. The project road fall under zone II (Low risk zone) and relevant provisions in IRC- 6:2010 have been adopted in the design. The seismic map of Tamil Nadu has been shown in Figure 12.

6. Water Resources and Hydrology

6.1 Drainage

143. Ground water occurs under water table, semi-confined and confined conditions. The important aquifer systems in the district are i) Lower Miocene deeper aquifers and ii) Pliocene – Quaternary shallow aquifers. The long-term water level fluctuation for the period 1998-2007 indicates rise in water level in the area in the order of (max.) 0.31 m/year. The fall in the water level ranges from 0.022 to 0.29 m/year.

144. As per the ground water quality assessment by the district groundwater board (May 2006), the chemical constituent’s Total Hardness (TH) as CaCO3 and NO3 are present in ground water in more than permissible limits. Other major ground water problems and issues are as follows:

▪ The mushrooming growth of aquaculture has lead to the pollution of ground water in the coastal part of the district. The quality of ground water in eastern and south- eastern parts is poor. ▪ The natural hydrodynamic conditions, is being disturbed every year due to natural or some manmade causes, results the lowering of water levels below mean sea level. The chloride-bicarbonate ratio indicates that the flushing is insufficient.

145. The major water bearing formations of the Thanjavur districts are recent alluvium, Cuddalore sandstone and Weathered and fractured gneissic rocks. The pre-monsoon depth of the water table (May 2006) is 1.55 – 18.32m bgl (below ground level) while post-monsoon depth of the water table (Jan 2007) is in the range of 0.22 -19.20 m bgl. Fluctuation in water level trend in 10 years (1998-2007) i.e. annual minimum rise is 0.0027 m/year and maximum of 0.3276 m/year, while minimum fall is in the range of 0.0097 and maximum of 0.7347 m/year. As per the ground water quality assessment by the district groundwater board (May 2006), the chemical constituent’s TH, NO3 and SO4 are present in ground water in more than permissible limits.

146. The quality of ground water in the coastal region is poor and unsuitable both for domestic and irrigation purposes. In the Tertiary aquifers there is fresh water zone below saline zone. Further development of ground water has to be carried out judiciously with sealing of poor quality formation water. 6.2 Drainage Conditions

147. Nagapattinam District: The district is drained by Kollidam and Cauvery in the north, Virasolanar, Uppanar in the central part and Arasalar, Tirumalairajan Ar, Vettar, Kedurai AR, Pandavai Ar, Vedaranyam canal and Harichandra Nadi in the southern part of the district.

148. Thanjavur District: The district is a part of delta formed by Cauvery River. It has gentle slope towards east and southeast. The Kollidam River forms the northern boundary and flow from west to east. The Grand Anaicut is located at the western boundary, at this point Cauvery splits into Cauvery and Vennar. A regulator at Tirukkatupalli splits Cauvery into Cauvery and Kodamurti rivers. At Thenperumbur anaicut Vennar splits into Vennar and Vettar. In addition to these, the rivers split into many streams before reaching the sea.

149. The project influence area is drained by tributaries of Cauvery and Kodilam Rivers. 47

6.3 Drainage and Water Bodies along the Project Road

150. Cauvery River is flowing parallel to the project road from the road starting point to km.35+600 on the left hand side. And Nattar river is flowing on right hand side. These river waters are being distributed to so many villages through minor irrigation system and the bridges in this location are constructed over these minor irrigation canals/drains only. All being minor irrigational canals the bridges constructed over these are minor bridges except at design chainage at km 13+756 and no overtopping conditions were observed on these bridges. The alignment crosses minor streams and irrigation canals. 151. There are many streams/canals crossing the project road. Ponds and lake are observed along the project road. Very few of them are partially impacted due to the proposed road improvement and none of the them are completely impacted. Details of the drainage channels, water bodies and likely impact observed along the project road are presented in Table 13 and Table 14.

155. The results of the ground water and surface water samples were analysed and presented in Table 16 and Table 17; respectively. It can be seen from Table 16 that all surface water quality parameters were well within the permissible limit of CPCB except the presence of Total Coliforms which represent present of organic matter in the surface water body.

156. From Table 17 it is clear that the ground water quality parameters were well within the permissible limits for drinking waters as specified by IS 10500:2012 on project road. Overall the ground water quality in the project areas is good.

8. Air Quality

157. The ambient air quality was monitored to characterize baseline scenario in the study area and direct project influence area. The study area comprises of rural, residential and urban areas. The sources of air pollution in the region are mainly vehicular traffic; dust arising from unpaved road and domestic fuel burning. The prime objective of the baseline air quality study is to establish the existing ambient air quality along the project road. This will also be useful for impact assessment during the construction and operation phases. In order to establish baseline 53 ambient air quality, monitoring locations were finalized following the notification of MoEFCC dated 16 November 2009; so as to be true representatives of the study area. Further, the locations were selected with the following considerations:

• meteorological conditions; • the assumed regional influences on background air quality; • the areas where impact would most likely be greatest; • present land use along the proposed alignment; and • traffic congestion points.

158. To establish the baseline air quality, Ambient Air Quality (AAQ) monitoring was carried out in last quarter of 2019 and air quality monitoring stations were set up at 2 locations as indicated in Table 18 along the project road.

Table 18: Ambient Air Quality Monitoring Locations along Project Road Sl. No Station Location Coordinates Land Use Aduthurai Town 11.0101.0N 79.2842.2E Residential 1 AAQ1 Area/Urban Natham 11.0825.3N 79.4142.5E Residential 2 AAQ2 Area/Rural

159. The two locations for ambient air monitoring was undertaken to represent air quality of the urban and rural habitation area with normal activities and traffic on the project road section. The averaging period is 24 hours for all parameters monitored, following National standards of air quality monitoring. Methodology adopted for sampling and analysis and instrument used for analysis in laboratory are presented in Table 19.

161. The monitored values are compared with National Ambient Air Quality Standards prescribed by Central Pollution Control Board (CPCB) IFC EHS standards for residential, rural and other areas. The Ambient air quality levels meet the National air quality standards for rural, residential and industrial area along the project road.

• PM2.5: The mean PM2.5concentration at ambient air quality monitoring locations varies from 22 to 29 µg/m3. The values are within the permissible limit at both the stations for CPCB but marginally exceed IFC standards.

• PM10:The mean PM10 concentration at ambient air quality monitoring locations varies from 55.2 to 61.9 µg/m3. The values are within the permissible limit at both the stations for CPCB but marginally exceed IFC standards.

• SO2: The mean concentrations of SO2at all ambient air quality monitoring locations varies from 17.1 to 21.8 µg/m3. The values are within the permissible limit at both the stations. • NOx: The mean concentrations of NOx at all AAQM locations range from 29 to 33.1 µg/m3. The values are within the permissible limit at both the stations. 55

• CO: The concentrations of CO at all AAQM locations were below 0.01 mg/m3. The values are within the permissible limit at all the Stations.

162. Overall the air quality along the project road is not an issue as per the National Ambient Air Quality Standards (NAAQS) prescribed by MOEFCC. However, the values for NO2, PM10 and PM2.5 are slightly exceeding the IFC EHS air quality standards. The National Ambient Air Quality Standards (NAAQS) prescribed by MOEFCC together with IFC standards are given in Appendix 4.

9. Noise

163. Noise in general is a sound which is composed of many frequency components of different loudness distributed over the audible frequency range. Noise in the project area was assessed using the GoI and IFC EHS noise guide values which are similar for day and nighttime residential and nighttime industrial land uses. The GoI is more stringent in commercial land use while the IFC EHS is less stringent for daytime noise for industrial land use. The IFC EHS does not provide guide values for silent zone which is defined as at least 100-meter perimeter around hospitals, educational institutions, courts, religious places and similar area. GoI standards when the existing noise levels already exceed the limits. IFC-EHS provides a 3 dB maximum increase from the background (i.e. doubling of noise levels) when the existing measure noise already exceeds the standards. GoI does not stipulate clear guidelines for such scenarios.

164. A preliminary reconnaissance survey was undertaken in project road to identify the major noise generating sources along the project road. To assess prevailing noise levels in the surroundings of project road, ambient noise monitoring was carried out considering all categories of land uses along the project road (e.g. commercial, residential and silence zones).

165. A total of 4 locations within the study area were selected for noise level measurements along the project road. The selected monitoring locations are representative of sensitive receptors in urban/semi-urban area and residential location from rural area. The background noise level at the monitoring location are generated from routine human activities and traffic on the road section in semi-urban and rural area. The monitoring location at N1 (residential) and N3 (silent zone) are in Urban and Semi-urban areas with traffic on congested road and commercial activities, while location at N2 and N4 are in rural area with normal activities and traffic volume. Thus, at these locations noise monitoring is done to observed maximum level and normal level of background noise. The locations of noise level measurement are shown in Figure 4 while location detail of the noise monitoring are given in Table 21.

Table 21: Details of Noise Level Monitoring Locations Sl. Sample Location Code Coordinates Land Use No (Village) Residential 1 N1 Kumbakonam 10.982112N 79.419105E Area/Urban Residential 2 N2 Aduthurai 11.01010 N 79.28422 E Area/Rural Residential Near Government 3 N3 11.04191 N 79.33340 E Area/Semi Urban Hospital,Kuttalam (Silent Zone) Residential 4 N4 Near Natham 11.08253N 79.41425E Area/Rural 56

1. Methodology: At each of the selected locations, Sound Pressure Level (SPL) measurements were taken at an interval of 1 minute using a sound level meter of Lutron make Digital Sound Level Meter. At all these locations, daytime noise levels were monitored during the period 6 am to 9 pm and night-time noise levels during the period 9 pm to 6 am following national guidelines. Noise readings, with setting at ‘A’ response - slow mode, were recorded. The readings were tabulated, and a frequency distribution table prepared from which 24 hourly, hourly, and average Leq noise levels were calculated. The baseline values were recomputed to align them with IFC EHS prescribed periods, which is 7am to 10pm for daytime and 10pm to 7am for nighttime.

166. Presentation of Results: It can be seen from the Table 22 that at all the monitoring locations the ambient noise levels exceeds the permissible limits for residential areas prescribed by CPCB and also by IFC EHS standards of 55 dB(A) and 45 dB(A) for day time and night time respectively. The maximum recorded day time noise level is 78.2dB(A) and night time noise level is 71.5 dB(A) along the project alignment.

C. Coastal and Marine Resources in Project Influence Area

167. Out of the total coastline of 1076 km in Tamil Nadu, Nagapattinam and Thanjavur (Project road district of Kumbakonam–Sirkazhi Road) share a length of 187.9 km and 45.1km; respectively. The project road does not fall under CRZ. In the coastal zone, there are several areas where development has already taken place before 1991. In 1991, the Coastal Zone Regulation notification was issued by the Union Ministry of Environment and Forests to protect the 500 meters zone from the high tide line and along rivers and creeks upto the area of tidal action. CRZ Notification 1991 has been amended in2011.The project road does not lie within 10 km from the coastline.

D. Biological Environment

1. Forests

168. The recorded forest area in Tamil Nadu state is 22,877 km2 which constitutes 20.21% of the geographical area of the state. Reserved Forests comprise 88.70%, Protected Forests 7.79% and Unclassified Forests constitute 3.51%. The forest cover in project districts is 57 presented in Table 23 which shows that project districts have very thin forest cover less than overall State forest cover. The RoW of the project road does not fall under any forest area shown in Figure 14 and thus does not attract forest land diversion.

2. Flora and Vegetation along the Project Road

169. The road side trees falling within formation width of project road have been enumerated as per the available design. The tree enumeration details of trees>30cm girth size along project road are provided in Table 24. The roadside trees are continuous throughout the corridor except some stretches where open land/agricultural land are observed. The trees are generally having good canopy as observed during environmental impact survey. Every effort has been made by engineering and environmental team to save these trees. There is no green tunnel along the project road.

2. Land Use

184. The landuse pattern of the project districts is presented in table 31. It is clear from the table 31 that Nagapattinam and Thanjavur District has majority of agriculture area. The forest cover in both the district is less than 2% while the net area sown the project districts is more than 50%. Most of the land surrounding project road is agricultural fields with intermittent rural/urban built- up structures. Also, it is to be noted that there is no forest land within 500m of project road. Table 30 indicates the % distribution of land use within 500m area of project road.

3. Economic Development

185. The economy of Tamil Nadu has grown steadily from a plan allocation of about ₹280 billion during 2012–2013, to about ₹606 billion during 2016–2017. The plan expenditure has grown by over 20% per annum during this period. Gross state domestic product and net state domestic product have been growing at over 10% from 2011–2012 to 2016–2017, though there is an expectation in the budget for 2017–2018 that these may drop below 10% in view of the impact of demonetization and introduction of the goods and services tax regime. From 2017– 2018, the concept of plan and non-plan expenditure is no longer followed and a substitute measure could be the capital expenditure as a proportion of the budget. The state budget mentions that it is paying special attention to capital expenditure. The allocation for capital expenditure is about 15% of the total budget expenditure for 2017–2018.

4. Agriculture

186. Agriculture is the most important occupation in the study area of the project road. Total cultivated land in the Nagapattinam district is 2, 70,874 hectares with net irrigated area of 147,564 ha with the majority of the area being irrigated from the canal and dug wells. Total cultivated land in the Thanjavur district is 192,030 hectares with net irrigated area of 193,670 ha with the majority of the area being irrigated from the canal and dug wells. Major crops grown in the project districts are given in Table 32 as follows:

Table 32: Agriculture Pattern of Project Districts Nagapattinam District Crop Area (in Ha) Area (in %) Paddy 1,58,100 58.20% Pulses 64,969 24% 71

Others 42,930 16% Thanjavur District Crop Area (in Ha) Area (in %) Paddy 1,54,901 80% Sugarcane 15,353 8% Banana 4,921 3% Other Crops 16,855 9%

187. It is clear from the table that the paddy is the main crop in both the project districts while pulses are also significantly grown in Nagapattinam District. The paddy crops are prominently seen in on both sides of the project road.

5. Archaeological and Historical Monuments

188. Road survey during DPR and preparation of this report revealed that there are no archaeological or historical monuments or physical cultural resources present along the road. No archaeological sites or historical monuments of state importance notified under Ancient and Historical Monument and Archaeological Sites and Remains Act, 1966 of Tamil Nadu nor of national importance notified under The Ancient Monuments and Archaeological Sites and Remains Act 1958 of India are located along the project road section.

6. Sensitive Receptors

189. During the environmental and social screening survey, number of sensitive receptors such as school, temple etc. are located along the alignment.

189.0 The list of sensitive receptors/structures on either side within 25m from center line of the road is presented in Table 33. These sensitive features along the road will be updated following the finalization of the resettlement plan by TNHD and the final detailed engineering design by the EPC contractor of the project road.

V. ANALYSIS OF ALTERNATIVES

190. This chapter presents the feasible alternatives to the proposed project with respect to site, design, technology etc. Since, the proposed project is an improvement of the existing road, no alternative alignments were considered for alternate route. Hence, an evaluation has been carried out for the ‘with’ and ‘without’ project situation-in terms of the potential environmental impacts for the justification of the project. This chapter discusses how environmental parameters were assigned due importance and were carefully considered in the analysis of alternatives. Apart from this, various alternatives for Vaitheeswaran Koil were considered based on technical feasibility, environmental and social parameters.

A. With Project’ and ‘Without Project’ Scenario (i) ‘With Project’ Scenario

191. The ‘with project’ scenario includes the widening of road section to two lane carriageway with paved shoulders configurations of the existing road section of Kumbakonam-Sirkazhi (SH- 64) in Tamil Nadu. The ‘with project’ scenario has been assessed to be economically viable and will alleviate the existing conditions. It would thereby, contribute to the development goals envisaged by State Government, and enhance the growth potential of the state through Chennai-Kanyakumari Industrial Corridor as well as the region.

192. To avoid the large-scale acquisition of land and properties, the project envisages the widening of existing road to two-lane with paved shoulders configuration and mostly along the existing alignment to minimize the loss of properties and livelihood of the PAPs.

(ii) ‘Without Project’ Scenario

193. In the case of ‘without project’ scenario the existing road with narrow carriageway width will be considered as it is. Considering the present traffic volume and potential for growth in near future, the capacity of the present road is insufficient for handling expected traffic volume and calls for immediate improvements.

194. The existing road section has poor riding condition, drainage, and geometry. Poor drainage is seriously impacting and deteriorating the road surface. The poor road conditions, population growth, increase in traffic volumes and the economic development along the project corridor would further exacerbate the already critical situation. The existing unsafe conditions and the adverse environmental consequences, in terms of the environmental quality along the roads, would continue to worsen in the absence of the proposed improvements.

195. Therefore, the no-action alternative is neither a reasonable nor a prudent course of action for the proposed project, as it would amount to failure to initiate any further improvements and impede economic development. Keeping in view the site conditions and the scope of development of the area, the ‘With-’ and ‘Without project’ scenarios have been compared as shown in Table 34. By looking at the table it can be concluded that “With project” scenario with positive/beneficial impacts will vastly improve the environment and enhance social and economic development of the region compared to the “Without project” scenario, which will further deteriorate the present environmental setup and quality of life. Hence the “With project” scenario with minor reversible impacts is an acceptable option than the “Without project” scenario. The implementation of the project therefore will be definitely advantageous to achieve the holistic development of the economy and progress of the State.

196. Based on analysis of “with” and “without” project scenario presented in Table 34, “with” project scenario, with its minor adverse impacts is more acceptable than the “without” project scenario. The potential benefits of the proposed road improvements are substantial and far- reaching both in terms of the geographical spread and time. Hence, it is clear that the implementation of the project with the environmental management plan for mitigation of adverse environmental impacts will contribute to the development of economy and progress for its people of the vicinity as well as environmental improvements.

B. Location and Alignment Alternatives

197. Detail discussion on Bypass proposal for the congested area along the existing road are given in following sections. The various options of alternate alignments were studied and feasible option is selected on the basis of comparative analysis of technical, social, environment and economical aspects..

198. Apart from engineering considerations of improving the curves or geometric along project road to IRC specifications, specific options of realignments that can improve the corridor's environmental performance by avoiding the removal of good old trees; avoiding the damage to community assets and religious places; avoiding old and narrow bridges, etc. were also considered. The project road widening and construction of bypass for Vaitheeswaran Koil will reduce congestion all along the road. The analysis of alternatives for these has been presented in table 36.

i. Vaitheeswaran Koil Bypass

199. The project road from km 47+100 to km 51+250 passes through the Vaitheeswaran town. This town has famous Vaitheeswaran temple and pilgrims in large numbers visit this temple all through the year. The RoW available is 10-16 m and upgradation of road to 2 lane configuration with paved shoulders is very difficult. Due to this a bypass has been planned for this habitation. The area around the Vaitheeswaran Koil was extensively studied and six alternative alignments were considered for the finalization of bypass alignment out of which ‘Option 6’ was found as most suitable option for due to technoeconomic, social and environmental considerations. Various parameters considered for finalization of alignment are given in Table 35 while all the proposed alternatives have been shown on Google earth in Figure-15.

200. The selected 'option-6' avoids the Vaitheeswaran Koil town from km 47+300 to km 51+900 has lesser length than other options except option-1. The option-1 has the disadvantage of closer to the built up locations. The options 2, 3, 4 and 5 have more lengths and require more land acquisition. These options have more impacts on water bodies, and buildings. The requirement of agriculture land is least in 'Option-6'. . The RoW for the bypass has been kept 45 m bare minimum to accommodate 2 lane cross section with paved shoulder. The selected option has least length, therefore, in terms of development, its cost will be least.

201. The Vaitheeswaran Koil bypass will avoid massive R& R problem and congestion in the town. The bypass will also be reduce air and noise pollution at this habitation. The accident reduction will take place at town and there will be no conflict between pilgrimage traffic and through traffic.

202. From the Table 35 and above discussion, it is clear that the selected option number 6 is the best option from environmental consideration also.

C. Design Decision Constraints For Various Alternatives

203. Road widening and design speed were considered for the various alternatives considered for the project. The design decisions were taken up considering the following factors also: ▪ Road submerges in rainy season; ▪ Public water taps and water tanks along the corridor; ▪ Religious structures; ▪ Road side ponds; ▪ Hand Pumps; ▪ Bore Wells and wells; ▪ Presence of canals and drains, and; ▪ Congested settlements.

D. Alignment Modifications due to Environmental Considerations

204. Theselection of the alignment / widening options along various sections has been worked out based on continuous interaction between the engineering design team and environmental study teams. Various alignment improvement alternatives (left/right) for the project road have been analysed along entire project road considering rural sections, and junction improvements. The factors considered for evaluation of alignment option are:

• Flora and fauna likely to be impacted; • Productive agricultural land likely to be impacted; • Impact on water resources and surface water bodies; • Environmental quality; • Land availability; • Land uses along the alignment; • Residential / Commercial structures Impacted; • Utilities likely to be impacted; • Common property resources likely to be impacted; and • Religious structures affected.

E. Engineering / Technological Alternatives

205. The formulation and analysis of engineering alternatives have been undertaken in terms of alternative cross-sections of road, highway-design principles (such as embankments for soil erosion and slope protections, hill cuttings, minimum width of road ride drainage, adequacy of roadway width at cross drainage structures, minimum gradient, etc.), comparison between flexible and rigid pavements (cement-concrete built rigid pavement as being environmentally superior then traditional flexible pavement), and selection of environmental friendly road construction methods.

VI. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

A. Introduction

206. This chapter presents key environmental issues associated with various aspects of the proposed project. The environmental impacts caused due to the development of the project road section were assessed on the basis of nature, extent and magnitude of likely changes due to project activities during all stages of the project cycle, i.e. preconstruction, construction and operation. Potential cumulative and induced impacts were also considered. Beneficial impacts are mostly long-term and permanent whereas adverse impacts are localized and temporary in nature and are likely to occur mostly during construction stage.

207. The methodology of assessing environmental impacts from the project entailed clearly identifying the environmental components that will impacted, type of impacts, assessment area where the impacts will be felt and defining the criteria for assessing the significance of each type of impact. After defining these aspects, a screening of project impacts during design and preconstruction, construction and operation stages of the project was carried out to identify the minor, moderate and major impacts to guide development of mitigation measures and ensure that there are no or minimal residual impacts.

208. Identification of impacts: This includes identifying the valued environmental components (VEC) of the physical, biological, and human environments that are at risk of being impacted by the project. The VECs for this project which are based on the environmental baseline are:

a. Physical environment: air quality and greenhouse gas emissions, land and soil, and groundwater quality and quantity. b. Biological environment: terrestrial and aquatic vegetation, mammals, avifauna, and ecologically important areas. c. Human environment: private land and buildings, public infrastructure including utility structures, noise and vibration levels, cultural/heritage buildings, and occupational health and safety for the construction workers and local community living within the vicinity of the project area.

209. Type of impact on the VECs: The type of impact can be described as:

a. Positive: Improvement in the quality of the VECs because of the project. b. Negative: Degradation or reduction in the quality of the VECs because of the project. c. Neutral: No noticeable change in VECs.

210. Area of impact assessment. The area covered for assessing direct impacts include:

a. The right of way of project road section is taken as 16 meters for urban stretches, 23 meters for rural areas, and 30 meters for bypasses 30m corridor. This includes 10m on either side studied for direct impacts (corridor of impact). b. Project area of influence is defined as ROW plus 500m on either side. 83

c. In addition, a 10 km buffer was studied for indirect impacts. Other indirect impact area covers location of quarries; borrow areas, storage area of construction material etc.

211. Significance of impacts. The assessment of the significance of the impacts on the VECs requires understanding the duration of impact, area of impact and severity of impact as follow

(i) Duration of the impact: Duration means the time dimension of the impact on the VECs. The terms permanent, temporary and short-loved are used to describe the duration of impact:

a. Short-lived: The impact is limited to particular activity/ies or phase/s of the project lifecycle b. Temporary: The impact is felt during one project activity or, at most, during the construction period of the project c. Permanent: The impacts are felt throughout the life of the infrastructure

212. Area of impact: The area of impact entails the spatial scale of impact on one or more of the VECs. The terms regional, local and limited are used to describe the area of impact:

a. Limited: The impact is felt within the corridor of impact b. Local: The impact is felt within the project area of influence c. Regional: The impact is felt beyond the project area of influence but within the 10km buffer zone

(ii) Sensitivity of VEC: The sensitivity of a VEC can be determined by the existing conditions of the VEC within the project area and existence of important VECs within the project areas. Sensitivity of each VEC is described as high, medium or low as described below.

a. Low: No environmentally important areas (such as protected areas, natural or critical habitat areas, heritage sites, places of worship etc.) are located within the direct and indirect impact zone. The quality of existing conditions of VECs is good or fair; b. Medium: There are one or more environmentally important areas within the indirect impact zone of the project area. The quality of existing conditions of VECs is good or fair; and c. High: There are one or more environmentally important areas within the direct impact zone of the project area. The quality of existing conditions of the VECs is poor or degraded (such as poor air quality, high noise levels, poor water quality)which makes the VEC highly susceptible to further deterioration.

213. Based on baseline conditions in the project area and sensitivity criteria, the level of sensitivity of each VEC is provided in Table 36.

Table 36: Sensitivity of VECs in the Project Area Sensitivity VEC Remarks Level Physical environment Air quality Medium The overall the air quality in the project area is average and within national permissible levels for the monitored parameters. However, the monitored values exceeds the World Bank group standards for PM10. GHG emissions Medium Firewood burning is the major contributor in the ambient pollution load. Vehicular pollution is a secondary source of pollution in the state as the traffic density is average. Surface water Medium Overall, the surface water quality in the project area quality is good, permissible levels are not exceeded for the monitored parameters. Natural river streams, many village ponds and lake, Irrigation Canal are main water bodies in CoI of the project. Surface water Low The project influence area is drained by tributaries of quantity Cauvery and Kodilam Rivers. The state has good water resources in the form of lakes, ponds, rivers and streams. The project area has sources of water potential both ground as well as surface water. Ground water Low Overall, the ground water quality in the project area is quality good, permissible levels are not exceeded for the monitored parameters. Ground water Low Since the project area has good surface water quantity resources the project will have sufficient sources of water for construction and groundwater abstraction will be negligible if needed at all. Land degradation Low There is no forest along the project road section, land and pollution use mainly agriculture and built-up. Land degradation and pollution is low. Biological environment Trees, terrestrial Low The project road does not passes through core and aquatic /buffer zone of any notified protected areas. There vegetation are no endangered flora species which are likely to be affected by the proposed project. Fauna (mammals, Low There are no vulnerable/ endangered or rare species birds, fishes, fauna around the project site. There is no presence of reptiles, any fauna species listed in Schedule I of the Wild Life amphibians) (Protection) Act, 1972 of Government of India. Ecologically Low The project is not located in core/ buffer zone of important areas protected area and no vulnerable/ endangered wildlife habitat is located near to road alignment. Social environment Private land and Medium The project upgradation will involve additional land buildings requirement of 19.7467ha of land out of which the 85

Sensitivity VEC Remarks Level Vaitheeeswaran Kovil bypass accounts for 12.047ha of land. Further, the project will cause impact to 740 Structures. The project will also impact 89common property resources. Public property/ Medium The ROW is available for widening or even minimum infrastructure/ utility improvement of road geometry, except at few structures locations. Impact on utility structures is expected due to shifting from current location. Noise Medium Existing noise levels are higher than the permissible limits for residential area in both daytime and night time. Vibration Low The structures are located away from CoI. Since road is existing one the vibration impacts are not expected to be high. Occupational Medium Road construction and increased traffic will lead to health and safety occupational health and safety risks.

Public health and Medium Influx of workers during construction and the safety construction activities may pose risks to communities along the project road and ancillary sites. The expected increase in traffic during operation stage potentially leads to an increase in unsafe situations. Physical cultural Low There are no adverse impacts anticipated on resources (PCR) historical places/monuments. However, there are small shrines along the road.

(iii) Severity of impact. The severity or seriousness of an impact entails understanding the repercussion or risks posed by the impact. This is a subjective criterion, which is defined as high, medium or low as below: a. High: The severity of impact is high if grave repercussions are expected as a result of the impact due to any of the following or similar situations: the impact will be felt by a large number of people or receptors; the receptors are highly sensitive; the impacts will cause serious health issues; there is already a history of complaints from the project area and people have raised significant concerns during public consultation; some of the VEC in the project area already severely degraded and maybe further worsened by the project; there will be a significant change in one or more VEC because of the project b. Medium: The severity of impact is medium due to any of the following or similar situations: the impact will be felt by a small number of people; some receptors are affected but they are not sensitive; the impact will not cause serious health issues; some concerns were raised during public consultations, but they were not significant; there will be minor changes in one or more VEC because of the project

c. Low: The severity of impact is low due to any of the following or similar situations: the impact will not be felt by anyone; no or limited receptors are affected; no concerns were raised during public consultations; there will be no noticeable changes in one or more VEC because of the project. 214. Based on the rating of duration, area and severity of impact as described above the overall significance of each impact as major, moderate or minor was determined as demonstrated in Table 37 below.

Table 37: Criteria for Rating the Significance of Impacts Significance Sensitivity Duration Area Severity Minor Medium or Low Short lived or Limited or local Low temporary or regional Low Permanent Limited low Moderate High or Medium Temporary Limited or local Medium or regional Medium permanent Limited Medium Major High Permanent or Limited or local High temporary or regional High or Medium Permanent Local or Medium regional

B. Screening of Impacts

215. Based on the rating criteria provided in Table 37, environmental impacts anticipated during the project design and pre-construction stage, construction stage and operation stage were screened for their level of significance as demonstrated in Table 38 below. The screening was carried out for impacts that are expected without mitigation. Hence, it guided the identification of impacts that need mitigation and pointing out significant/major negative impacts that need to be prioritized for mitigation.

216. The significance of each environmental impact or project activity is indicated by the colors of the cells in the last column of the table. Red indicates major impact, orange indicates moderate impact, yellow indicates minor impact and green indicates positive impact. The following section discusses the details of impacts on each of the VECs in line with identification of major, moderate, minor impacts in the screening matrix. Major impacts have been given priority for identification of mitigation measures to ensure that there are minimal or no residual impacts. 87

: positive impact : minor negative impact : moderate negative impact : major negative impact

C. Typical Potential Adverse Impacts

217. Identification and assessment of the potential environmental impacts are based on secondary information supplemented by field visits. Impacts on various environmental components have been assessed at four different stages, namely:

• the project location; • design and pre-construction; • construction; and • operation stages.

D. Impacts on Physical Environment

1. Air quality and Greenhouse gas emissions

Design and pre-construction stage – minor negative impact 2. The project aims to improve a section of 36.799 km of the existing state highway no. 64. Based on the capacity augmentation the present road section is proposed for improvement and upgrading to a two lane configuration with shoulders and side drains. TNHD considered minimum clearing of trees and vegetation and will have minimal impact on the air quality and GHG emissions. A total of 1,466 trees >30 cm girth will be cleared for the road widening which is about 40% less than standard clearing requirements for the scale of widening since extra care was taken to minimize impacts on trees. Carbon sequestration capacity lost through clearing of trees is roughly 21 kg CO2/year per mature tree. These will be replaced with 10 saplings per cut tree whose survival (70%) will be ensured through monitoring and replacement. Each sapling has the ability to absorb roughly 5 kg CO2/year which largely offsets carbon sequestration capacity lost. More details on afforestation are under the section on Trees and Vegetation.

Construction stage – moderate negative impact

218. Impact: During construction air quality may be negatively impacted for short periods due to (i) the exhaust emissions from the operation of construction equipment and machinery; (ii) fugitive emissions from brick, concrete, and asphalt plants; (iii) the dust generated from the haulage of materials, exposed soils and material stockpiles, fugitive dust from earth-moving operations and demolition; (iv) cutting and filling of hill slope; (v) cleaning of the road; (vi) material loading; (vii) unloading; and (viii) increased traffic congestion in construction areas. The impact is expected to be localized, temporary and confined to construction areas. Care should, however, be taken at sensitive habitation locations so that harmful impacts can be minimized. The adverse impacts on air quality during construction stage were classified and presented in Table 39. There are two types of pollution i.e. dust pollution and pollution from harmful gases.

Table 39: Impact on Air Quality During Construction Stage S. No. Impact Source 1. Generation of dust • Excavation activities • Transportation and tipping of excavated material - while the former will occur over the entire stretch between the cutting location and disposal site, the latter is more location specific and more intense; • Transportation of raw materials from quarries, 91

borrow, and disposal sites; • Stone crushing, handling and storage of aggregates in asphalt plants; • Site leveling, clearing of trees, laying of asphalt, construction of bridges; • Concrete batching plants; • Asphalt mix plants – due to the mixing of aggregates with bitumen; and • Construction of structures and allied activities 2. Generation of • Hot mix plants; harmful • Large construction equipment, trucks and asphalt emissions including producing and paving equipment; SO2, • Toxic gases released through the heating process NOx and HC during bitumen production; and • Inadequate vehicle maintenance and the use of adulterated fuel in vehicles.

219. Mitigation measures. The project road section mainly passes through agriculture areas and presently air/dust pollution is not a major issue. In order to suppress any negative impact from the generation of dust during construction there will be regular watering of the road surfaces and exposed spoils or the application of emulsion coats near villages, where dust is a nuisance. Provisions will be incorporated into the contractor’s contract to require the use of dust suppression measures.

220. As it is expected that suspended particulate matter (PM10) levels will increase during construction, certain mitigation measures are suggested in order to keep these levels within the permissible standards. The following actions should be implemented:

• regular check-up and maintenance of construction equipment is required; • idling of engines is strongly discouraged; • mixing plants i.e. asphalt, concrete, and bricks, should be operated within the permissible limits of CPCB and IFC EHS, and located away from settlements; • the contractor will submit a dust suppression and control programme to the PIU prior to construction – this plan details actions to be taken to minimize dust generation and identify equipment to be used; • vehicles delivering loose and fine materials should be covered to reduce spills and speed limits should be imposed; • bitumen emulsion should be used wherever feasible; • no unauthorized burning of C&D waste materials; • bitumen heaters should be used and the use of wood for fuel prohibited, and • Ambient air quality monitoring shall be done regularly at representative sensitive locations to ensure that all the emissions from construction activities are within CPCB and IFC EHS standards and therefore ensuring the effectiveness of mitigation measures taken.

221. Residual Impact. With the proper application of the proposed mitigation measures a residual impact on the air quality during construction phase will be minimal.

Operation stage – minor negative impact

222. Impact: To assess the likely impact on air quality at the various locations along the project road corridor, the prediction of the pollutant concentrations has been carried out using AERMOD, a dispersion model based on Gaussian Equation. Detailed analysis is presented in Appendix 7. The input parameters for the prediction are detailed in subsequent paragraphs.

223. The AERMOD atmospheric dispersion modeling system is an integrated system that includes three modules: (a) A steady-state dispersion model designed for short-range (up to 50 kilometers) dispersion of air pollutant emissions from stationary industrial sources. (b) A meteorological data preprocessor (AERMET) that accepts surface meteorological data, upper air soundings, and optionally, data from on-site instrument towers. It then calculates atmospheric parameters needed by the dispersion model, such as atmospheric turbulence characteristics, mixing heights, friction velocity, Monin-Obukov length and surface heat flux. (c) A terrain preprocessor (AERMAP) whose main purpose is to provide a physical relationship between terrain features and the behavior of air pollution plumes. It generates location and height data for each receptor location. It also provides information that allows the dispersion model to simulate the effects of air flowing over hills or splitting to flow around hills. AERMOD also includes PRIME (Plume Rise Model Enhancements) which is an algorithm for modeling the effects of downwash created by the pollution plume flowing over nearby buildings. Various input parameters for the prediction of pollutant concentrations are discussed below:

224. Traffic Volume: The fleet wise traffic volumes for the present study have been taken from the detailed feasibility report of the project. The annual average daily traffic (AADT) data is available for the proposed road through traffic survey. AERMOD model needs hourly average traffic volume. The total traffic hour volume is further categorized in to two wheeler, four wheeler, Light commercial vehicles (LCVs), Bus and high commercial vehicles (HCVs), based on the traffic survey at different road stretched along the highway. The annual average daily motorized traffic data are given in Table 40 with projected future traffic growth.

Table 40: Annual Average Daily Traffic Data Year 4W LCV Truck Bus 3W 2W 2020 5075 2379 814 2114 941 16760 2025 7436 3037 1064 3087 1387 24597 2030 10499 3875 1366 4345 1970 34786 2035 14339 4946 1745 5918 2704 47560

225. Emission Factors: Emission factor is one of the important input parameter in AERMOD model. In the present study, the emission factors specified by the Automotive Research Association of India (ARAI, 2007) have been used for calculation of weighted emission factors. These emission factors have been expressed in terms of type of vehicles and type of fuel used (for petrol and diesel driven passenger cars). The emission factors used in the present study for different vehicles type are given in Table 41.

226. Meteorological Conditions: The meteorological parameters such as wind speed, wind direction, temperature, rainfall, cloud cover, pressure, and humidity were used in model. Meteorological parameters observed during environmental monitoring carried out in the month of December 2019 were used for the model and is given below Table 42.

227. Receptors: A set of link receptors were taken at various receptor locations within each section at a distance of 10 m, 20 m, 50 m, 100, 200 m and 500 m both sides from center line of the carriageway to know the dispersion of pollutant from the road.

228. Background Concentration: The background pollutant concentrations were taken from environmental monitoring data. Air quality monitoring was carried out in the month of November

2019 at two locations along the alignment on two alternate days in a week. The background pollutant concentrations that were taken for model predictions are listed in Table 43.

Table 43: Average Background Concentration of Pollutants along the Alignment

229. Predicted Pollution Levels: The model has been setup and run to predict hourly average of CO and 24 hourly average of PM2.5, PM10, NOx and SO2 concentrations for the years 2020, 2025, 2030 and 2035 using forecasted traffic data on proposed highway. The predicted hourly average concentration of CO, PM2.5, PM10, SOx and NOx during peak traffic are shown in Tables 44 to 48 for proposed highway project. 95

230. Green House Gases Emissions: Upgrading and strengthening the surface condition of existing SH-64 road under project will bring about a change in vehicle operation speeds, traffic composition on the highway. Such changes with respect to present conditions will have an impact on emission levels of the gases emitted by vehicles travelling along the section of SH-64 highway. Most common types of vehicles that would move on the particular section are motor cycles, three wheelers, cars, vans, buses, light and heavy commercial vehicles. Thus, emission of Carbon Dioxide (CO2) from motorized vehicles which is a GHG needs to be analyzed to evaluate the overall contribution of this investment program in terms of the change in CO2emissions.

231. Evaluation Knowledge Brief has developed a set of spreadsheet-based models to evaluate the CO2 impacts of rural roads. These Transport Emissions Evaluation Model, for projects (TEEMP) consider passenger and freight travel activity, the shares of trips by different modes and vehicle types (structure), fuel CO2 efficiency (intensity), and fuel type, validated by more detailed emission factor models. The models directly estimate CO2 emissions for a business-as-usual case (a no-action alternative) vs. alternative including improvement to road pavement and calculate scenario differences.

232. The TEEMP model for rural/urban roads was used for the analysis with using default parameters for base fuel consumption, emission factor and upstream emission percentage.Occupancy-loading,averagetriplengthsofeachtypeofvehicle,vehicletype growth and roughness factors (before and after improvements) were fed to the model based on the details of traffic and economic analysis for the two sections of SH-64 road. The model was run separately for the road section. The traffic data used in the model is given in table-40.

233. Model output includes CO2 emissions at Business as Usual (BAU) or without project; with project (i.e. with improvements) and with induced traffic; and with project and without induced traffic.

Table 49: CO2 Emission at BAU, Project with and without Induced Traffic Parameters Emission of CO2 in Ton/km/year BAU 868.76 Project with induced traffic 854.71 Project without induced traffic 854.71 Net reduction in CO2 emission 14.05

234. As indicated in the model output summarized in above Table 49 the proposed improvement to existing highway pavements will bring a reduction in CO2 emission even with a growth of traffic. However, this analysis is based on the assumption that the roughness of improved highway pavement surface will be maintained during the project life. Therefore, it is important that the road maintenance program is maintained throughout the project life. The total length of SH-64 to be improved is 36.799 km. Based on the net change in CO2 emissions or CO2 savings of the sections is 14.05 Tons/km/year, and thus the proposed investment program of SH-64 as will save emissions of 517.04 Tons CO2/year.

235. Mitigation measures: It has been observed from the model output that when the traffic volume increases, the concentration of air pollutants also increases correspondingly. However,

the maximum predicted pollutant concentrations of CO and SO2 over the existing ambient air quality are found to be within the National Ambient Air Quality Standards of CPCB and exceeding for PM2.5, PM10, and NOx. The predicted pollutant levels are higher than the IFC EHS guideline limits for all the parameters monitored. Since the project will improve the road conditions it is not expected to cause significant increases in existing concentrations of pollutants. However, pollution from reanimation of dust on the road will remain a concern. Proper and regular maintenance of roads will decrease these indirect impacts. The details of air quality modelling and pollutant dispersion along the alignment is given in Appendix -7.

236. Residual Impact. The TEEMP and AERMOD models show that the project is likely to result to increase in air pollutants due to emissions but not in significant concentrations when compared to baseline values. Therefore, the project will have minor residual indirect impact on the air quality. 2. Surface water quality and quantity

Design and pre-construction stage – moderate negative impact

237. During preliminary planning and design of this project, the Consultant has taken into account the need for:

• reduced incidence of embankment erosion due to inadequate drainage; • providing adequate culverts/drains; • providing side-drainage structures.

238. Impact: Given the presence of rivers/stream, canal and ponds along the project road and some of the seasonal stream crossing the project road, improvement of road may result in disruptions to the natural hydrology and water mismanagement and lead to further problems of soil erosion.

239. Mitigation Measures. The natural courses of rivers/streams will be maintained. Appropriate temporary diversions of streams will be made and brought back to their natural course as soon works are completed in that section. Regarding design, the following should be followed:

• drainage structures are properly designed to accommodate forecast discharges; • side drain waters must be discharged at every available stream crossing to minimize volume and prevent erosion at discharge point; • provide lined drainage structures; • where an increased discharge of surface water endangers the stability of the water outlet, erosion protection measures such as bioengineering measures, ripraps, and check dams are incorporated; and • in areas with high water tables, seepage may occur, and side drains and up-slope catch drains must always be lined to avoid percolation.

240. Residual Impact. With the proper application of the proposed mitigation measures residual impacts on the surface water quality and quantity will be minimal.

Construction stage - moderate negative impact 99

241. Impact. Minor impacts on water resources are expected during the construction phase construction site runoff, wastewater discharge, etc. The rehabilitation of existing bridges may also cause soil erosion and turbidity in downstream water bodies.

242. The likely impacts of surface water movements are changes in the natural drainage systems, downstream scour, and erosion due to constriction in flows. If suspended solid concentrations in the water are affected, this could also affect aquatic river ecology. However, these impacts are expected to be minor as there are no perennial rivers along the proposed road alignment and construction will take place during dry period.

243. Mitigation Measures. To mitigate this, river-bank slope stabilities will be monitored and, if necessary, appropriate remedial measures applied throughout the construction period. Construction work at bridges during rainy season will be minimized to avoid erosion and sedimentation.

244. To mitigate these impacts the following measures should be implemented:

• maintain adequate vegetative cover on unpaved shoulders of the road; • maintain the natural course of water bodies (as much as possible) and no throwing of C&D spoils into water bodies; • chemicals and oils are stored in secure, impermeable containers, and disposed of well away from surface waters In an environmentally sound manner while adhering to applicable laws and regulations; • no vehicle repair/cleaning activity is allowed within 300m of water bodies/drains; • construction camps are equipped with sanitary latrines (septic tanks); • construction establishments such as construction camps, labor camps, asphalt/concrete mixing stations, stone crushing units should be located away from the water bodies. Domestic and sewage wastes from labor camps shall be treated with a sewage treatment system (septic tanks) to comply with the standards specified by CPCB and WBG before disposal. Testing of effluent has to be done in accordance with the rules and regulations of CPCB and SCPB the work on bridges and culverts is limited to dry seasons, when many of the smaller streams will have low water - water diversion works can be minimized, and the original course restored immediately after the work has been completed; drivers are made aware of diversions and other works at bridge construction site to avoid accidents; • drainage structures are properly designed to accommodate forecast discharges; • side drain waters must be discharged at every available stream crossing to minimize volume and prevent erosion at discharge point; • provide lined drainage structures; • where an increased discharge of surface water endangers the stability of the water outlet, erosion protection measures such as bioengineering measures, ripraps, and check dams are incorporated; • in areas with high water tables, seepage may occur, and side drains and up-slope catch drains must always be lined to avoid percolation; and • all debris and vegetation, clogging culverts are regularly cleared.

245. Residual impact. With the proper application of the proposed mitigation measures a residual impact on the surface water quality and quantity during construction will be minimal to moderate.

100

Operation stage – neutral impact

246. Once construction is finished no impact on the surface water quality and quantity is expected. In order to check if unexpected erosion and siltation (including accidental spillage of pollutants from vehicles) in major water bodies is happening periodic surveillance will be conducted and mitigation measures will be taken if necessary. 3. Groundwater quality and quantity Design and pre-construction stage – neutral impact

247. No impacts are envisaged during design and preconstruction stage.

Construction stage - minor negative impact

248. Impact. The quality of the groundwater could be impacted at sites where process water or wastewater is generated and disposed of in an improper manner. This could be the case at labor camps, at temporary construction sites and at fuel stations. Quantity may be affected if construction water requirement is obtained from groundwater sources.

249. Mitigation Measures. Sewage generated at labour camps will be disposed in septic tanks which may be emptied periodically through local sewage disposal system. Latrines should be located away and downstream of any source for drinking water in order to prevent accidental contamination of drinking water sources. All latrines will be connected with a septic tank to ensure sewage is not released into the environment. Locations for fueling and/or maintenance should be fitted with impervious flooring and a drainage system connected to an oil/water separator and settling tank to treat sewage before being discharged. Fuel tanks shall be placed in a catch basin large enough to hold the entire contents of the tank and an additional ten percent. More detail on the layout and requirements for labour camp and construction sites can be found in Appendix 8: Plant Management and Appendix 9: Camp Site Management.

250. Construction water requirement (avg. 400 KLD and peak 450 KLD) will be met through CGWB approved ground water source. Domestic water requirement (30 KLD) for workers will also be met mainly through approved sources only. Necessary permits will be obtained prior to water abstraction and only when there is no other viable option so as not to compete with local domestic demand. It is envisaged that groundwater will be utilized for camp domestic water requirement if there are no other viable sources or if the safety of workers will be at risk. Water abstraction will be included in monitoring.

251. Residual Impact. With the proper application of the proposed mitigation measures a residual impact on the groundwater quality will be minimal during construction.

Operation stage – neutral impact

252. During the operation stage of the project no impacts on groundwater quality or quantity are foreseen. 4. Land degradation and pollution

Design and pre-construction stage – minor negative impact 101

253. Impact: Construction activities of the project road will bring permanent changes in the local-level topography and appearance of the project site. There will be a change in aesthetic beauty of the project area mainly due to the earthwork.

254. The use of proper sources for stone and aggregates has become a major issue in most of the region. Historically, stone has been collected from the roadside or from shallow surface workings. Small quarries on steep slopes are often enlarged by blasting or excavation at the base. This is dangerous and can cause slope failures. Roadside stone collection continues in some districts despite its proven negative impacts on road safety and stability.

255. Sand and gravel are often obtained from river deposits. Jurisdiction over stone and aggregates is shared between the Geological Survey of India and the State Forest Department. The Geological Survey of India issues licenses for major mineral developments while the Forest Department issues permits for stone quarrying and for sand and gravel extraction. This is largely because these are mostly found on forest lands. Roadside quarrying is officially discouraged, but unofficially continues, invariably by petty contractors.

256. The engineering team as part of material survey has identified and recommended sources of the construction materials. Details of these sources are provided in Volume 1 (Material survey chapter) of Detailed Project Report. As a prior requirement of project, every new quarry and borrow area should also be subjected to a site-specific environmental investigation work according to an approved plan; and should be left in a safe condition or restored to a productive land use. Subject to these conditions, obtaining construction materials for projects will not cause unacceptable impacts.

257. Mitigation Measures. During preliminary planning and design of this project, the Consultant has taken into account the need for:

• optimization of the center line so that embankment raised on both side; • temporary and permanent drainage systems to minimize soil erosion; • optimum siting and control of quarries; and • mechanized construction methods.

258. The following should be considered during finalization of detailed engineering design:

• Minimize permanent and temporary land take for development • Optimize balance between cut and fill and avoid deep cuts and high embankments to minimize earthworks • Maximize reuse of spoils and old asphalt paving material within the construction • Agree on spoils disposal sites, management and rehabilitation plan with relevant local agencies • Specify vegetation that serves specific bioengineering functions.

259. Adequate earth material is available from barren land in the vicinity. Estimated quantity is 128400 cum of borrow earth and 2,35,000cum of aggregates will be mostly sourced from licensed quarries available locally. Tentatively it is proposed that the aggregates and boulders will be sourced from previously approved quarry area located near to the project road. Earth cut materials will be maximized for reuse in backfilling on the same rural road to minimize the quantities of borrow materials and spoil disposal. Borrow earth material will still be required but this will be taken from quarries or riverbeds after prior permission from competent authority.

102

• If new borrow areas are opened for the project, they should obtain necessary clearances; • borrow areas are not established in ecologically sensitive areas; • villagers are consulted in regard to the design and location of all borrow areas – these should ensure the safety of local communities and, if possible, should incorporate beneficial post construction features for the villages; • located away from the road as well as the road, so as to minimize visual and slope stability impacts; • construction facilities such as temporary workers camp, hot mix plants, and concrete batching plant and stone crushers will not be established in reserve / protected forests. Local forest department / village panchayat committees should be consulted before locating these temporary project facilities; • construction camps for labourers should be located at a suitable distance away from settlements in accordance with relevant national or state regulations such as the State Pollution Control Board and in a manner to avoid stressing local resources (water, electricity etc.) and away from forest/protected areas as per recommendations of local forest department; • living accommodation and ancillary facilities should be erected and maintained to standards and scales approved by the CSC; and • toilets and urinals should be provided in accessible places away from the asphalt plant and mixing yard.

260. Residual Impact. With the proper implementation of the proposed mitigation measures and low likelihood of the project requiring opening of new quarry sites the project is not expected to have a significant residual impact on the soil and local topography.

Construction stage - moderate negative impact

261. Impact. There may be permanent changes in the landscape. Disposal of excavated soils and debris at improper locations such as low laying area will make the area look untidy and unattractive. Disposal of waste and litter at improper locations and deforestation for firewood will make the area look dirty and unattractive.

262. During the improvement works for the road section, the cutting of trees, stone quarrying, and construction of structures, the micro-level topography may change. With proper planning, these topographical impacts can be kept within acceptable limits and sometimes even used to enhance local aesthetics. Any negative impacts on topography (existing or new), particularly soil erosion due to a lack of drainage facilities, will be minimized with the provision of proper drainage facilities such as culverts etc. The overall impact on topography is, therefore, anticipated to be insignificant.

263. The terrain and geological conditions of area is plain, hence the interaction between proposed road features and existing land features will not reveal/result in significant land instabilities.

264. Given the low gradient slope and lack of proper drainage in almost entire project area, it is inevitable that the project site will face problems of erosion. Unstable, uncompacted road embankment materials and exposed material can result to soil erosion, clogging of side drains and the spill-over of rainwater runoff onto the road surface. These problems can be mitigated by maintaining the batter gradients as specified in the MORTH guidelines. The existing vegetation on embankment slopes the immediate area of construction must remain undisturbed during 103

construction and/or upgrading. Grass seeding will be used to prevent barren embankment and to stop soil erosion. Support structures will be installed where slope failures are anticipated or may have occurred previously.

265. Construction work in the project road section will be virtually through plain terrain and stable slopes. Much of areas in this section are surrounded by agriculture fields with adequate natural drainage of storm, resulting in stable substrates.

266. The project will require large amounts of bitumen or bitumen emulsion usually stored in drums. These empty bitumen drums are generally recycled as steel sheeting or used in road construction as parapets or for riverbank stabilization. When supplied and used in this manner, bitumen, if not containing Polycyclic Aromatic Hydrocarbons (PAH), is not regarded as a significant environmental hazard.

267. The project will require the import, transport, and use of fuel and oils. Minor diesel spills are common in region, especially around fuel stations.

268. Mitigation Measures. During the construction phase the existing vegetation including shrubs and grasses along the road (except within the strip directly under embankments or cuttings) should be properly maintained. Sites for quarrying, borrowing and disposal of spoils are to be confirmed according to the applicable laws and regulations in the state and the practices followed in recent/ongoing internationally funded road projects. Major excavation and earthworks should only be undertaken during the dry season.

269. Quarry and borrow pits may be filled with rejected construction waste such as top soil etc. and afterwards should be given a vegetative cover. If this is not possible, then the excavated slopes will be filled in such a way that they resemble an original ground surface.

270. Mitigation measures for quarries are:

• aggregates will be first sourced from licensed quarry sites (which are in operation) that comply with environmental and other applicable regulations; • quarries must use controlled and environmentally friendly quarrying techniques in order to minimize erosions and landslides (Appendix 12 provides guidelines for quarry management); • occupational safety procedures/practices for the work force will be adhered to in all quarries; • quarry and crushing units will be provided with adequate dust suppression measures; and • regular monitoring of the quarries by concerned authorities to ensure compliance with environmental management and monitoring measures.

271. Mitigation measures for borrow areas are:

• prior approval will be obtained from concerned authorities and all local environmental regulations be complied with; • within all identified borrow areas, the actual extent of area to be excavated will be demarcated with signs and access to the operational area controlled; • borrow pit plant and machinery will conform to CPCB and IFC EHS noise emission regulations;

104

• protective gear will be provided to the workforce exposed to noise levels beyond threshold limits and there should be proper rotation of such personnel; • all operation areas will be water sprinkled to control dust levels to national ambient air quality standards, and • borrow areas are provided with gentle side slope that are connected to the nearest drainage channel to avoid the formation of cess pools during the rainy season.

272. Other mitigation measures to be taken during the construction phase are:

• Any temporary lands required for labour camps or any other sites required for the project shall be transferred back to the owner after the land has been restored to its original state before the completion of construction works. Contractor has to collect baseline data on the quality of ambient air, ambient noise, soil, surface water and groundwater before establishing and after decommissioning the camps or sites; • excavated material shall be stockpiled and covered in such a way the soil will not erode away and should be used to widen the road or disposed of at proper disposal sites following spoil disposal management guidelines (Appendix 10); • Removal of bituminous wastes from existing roads should not be disposed of in nearby water bodies, open spaces and parks and wastes should not be left unmanaged on the road sides. Bituminous material should be examined for PAH to establish if it can be recycled/reused for road construction. If not, the bitumen shall be treated as hazardous waste and disposed of in pre-identified and approved disposal sites”; • Any construction and demolition waste generated during the construction phase should be managed in accordance with the C&D Waste Management Rules, 2016. As far as possible, demolition and construction waste should be segregated and recycled. The unserviceable waste left after recycling should be dumped in pre- identified and approved pits as per Construction & Demolition Waste Management Rules. All required permissions shall be obtained from the concerned authorities before disposal of the debris”; • cut slopes should be re-vegetated immediately after widening activities; and • cut material should be disposed of in suitable depressions.

273. To mitigate the impacts of possible fuel spills the following measures will be applied:

• secondary containment around fuel tanks large enough to hold the entire contents of the tank and an additional ten percent and at fueling stations will be built; • oil and fuel spills, and other runoff from contaminated areas will be controlled; • equipment and fuel depots will be placed in safe zones away from drinking water sources and riverbanks; and • the project will provide an opportunity to assist the PIU and contractors in improving fuel handling practices so as to minimize future fuel spillage.

274. Appendix-8 to Appendix-12 of this IEE Report presents good environmental management practices and guide documents in the following aspects of road construction:

• Plant Management – Appendix 8; • Camp Site Management – Appendix 9; • Debris Disposal and Spoil Management – Appendix 10; • Borrow Area Management – Appendix 11; 105

• Quarry Area Management – Appendix 12.

275. Residual impact. With the proper application of the proposed mitigation measures the construction phase should not have any significant residual impact (except minor impacts for the initial years) on the soil or the local topography.

276. Operation stage – positive impact

277. Repairs to culverts and new drainage work will eliminate/reduce the soil erosion problems presently caused by poor cross drainage. The situation will remain good because this road passes through an area that is largely agriculture fields and trees and plants have the capacity to stabilize the soil and prevent soil erosion.

E. Impacts on Biological environment

1. Trees and vegetation

Design and pre-construction stage – moderate negative impact

278. Impact. The improvement work will be kept limited to existing ROW with minimal additional land acquisition. Nonetheless, land clearing will involve cutting of trees and horticulture shrubs within the ROW along the road.. The improvement of the proposed road is largely confined on the existing alignment. However, improvements to the geometry may involve excavation and filling and the need to clear vegetation.

279. Mitigation measures. To minimize loss of trees, the following mitigation measures have been adopted during the detailed design and construction stage of the project:

• widening proposal considered option with minimal tree cutting; • adopting Environmentally Friendly Road Construction (EFRC) methods; • Under the mandatory afforestation program approximately 14660 trees will be planted within the project area. • The plantation under compensatory afforestation plan will be scheduled within 15 months of the construction works, as preparation of seedlings in the approved nursery will start with commencement of construction work for the project road. • Budget provisions for following the mandatory afforestation program which requires planting native trees at the rate of 1:10 for trees cut (146600 in total) and improving vegetation cover in the project area.

280. Residual impact. As a result of the proposed afforestation program and additional improvement activities it is expected that there will be a net gain of trees and vegetation under the project.

Construction stage – moderate negative impact

281. Impact. Removal of trees for road widening etc. will result in temporary loss of habitat and associated biodiversity. The project will not require diversion of any forest land for widening of the road. Only vegetation within ROW will be cleared after approval from revenue department.

106

282. Another impact from road construction activities and deriving from the vehicle movement, quarrying, preparation and transfer of material and other earthwork is the accumulation of dust on the surrounding vegetation. This leads to deterioration of the vegetative health, which in turn will affect the ecology as well as the aesthetic beauty of the area. Induced impacts may also result from the following:

• increased tree harvesting for firewood, construction timber, forage, medicinal plants, and other products; • increased earth and rock extraction; and • construction crew demands for wood as a fuel and for building materials.

283. Invasive Species: Soil brought into the project area from outside may contain seeds of alien invasive species. Also, the construction machinery and vehicles can accidentally introduce seeds of such plants if used without proper cleaning. This will negatively affect both the natural and manmade habitats. Securing soil from locations close to the project area will reduce the chances of transporting any seeds of alien invasive species to the project area.

284. Mitigation Measures. Compensatory afforestation plan will be developed in consultation with local forest department. In detail, the recommended mitigation measures include:

• Compensatory afforestation plans; • Cut only trees which are necessary. Ensure that the vegetation is cleared as per terms and conditions of tree cutting permit; • Compliance with guidelines issued by the Indian Road Congress; • all wood building material for workers’ housing should be brought from outside the project area; • workers should be supplied with non-wood fuels such as kerosene or liquefied petroleum gas for the duration of the contract; • Prohibit collection, sale or purchase of timber/firewood by staff and contractors, with heavy penalties applied; • all contract equipment and plants should be cleaned to the satisfaction of the CSC in charge prior to their relocation to project sites; • during site clearance, care should be taken to ensure that the minimum area of vegetation area is affected; • water sprinkling of trucks used as construction vehicles should be properly and regularly undertaken, so that dust deposition problem on vegetation are minimized. Cleaning/washing of construction vehicles arriving in the project area; and • Securing soil from locations close to the project area will reduce the chances of transporting any seeds of alien invasive species to the project area.

285. Residual Impact. With the implementation of the measures above, minimal residual impacts on trees and vegetation is expected.

Operation stage – positive impact

286. Impact. A net gain of good vegetation cover is expected as a result of the mandatory compensatory afforestation program. It is expected that vegetation such as shrubs, herbs and bushes will reestablish themselves within one to two years after project construction. However, the trees will take longer 5-10 years to attain substantial growth. Hence, there will be no residual 107

impacts in relation to smaller vegetation species such as shrubs, bushes etc. Residual impacts in relation to mature trees will be mitigated eventually after 5-10 years after project construction.

Operation stage – positive impact

2. Ecologically important Areas

Design and pre-construction stage – moderate negative impact

287. Impact. The project road section passes though plain terrain with agriculture areas residential areas in between. Road section is not passing through any forest and protected area. Ecologically important areas within the project area includes water bodies. There may also be a low risk of disturbance to wildlife from traffic noise of the project road.

288. Mitigation Measures. Measures to protect surface water resources such as appropriate drainage design to accommodate predicted water volume and minimize impacts on existing waterways will help address these impacts on ecologically important areas and wildlife. Undertaking pre-construction survey along the alignment to identify the section required for protection measures by the EPC contractor will further address fragmentation effects of the road improvement.

289. Residual impact. If the above mitigation measures get implemented as planned, minimal residual impacts are expected due to project design.

Construction stage - moderate negative impact

290. Impact. Temporary sedimentation and water quality deterioration is expected during the construction stage. Increase in turbidity due to erosion will lead to reduction of light penetration and make it an undesirable place for aquatic fauna and flora. Further due to the reduced light penetration to the water body, the primary productivity of the biota in the water body will be reduced resulting in increased mortality. The impact is insignificant since construction of road section in the area will be mostly during summer and short-term only. Siltation will be avoided by measures suggested above in impact on surface water resource section. Construction crew demands for food and recreational hunting and fishing may also result to poaching during construction.

291. Impacts on Protected Area: The project road does not pass through any reserved/protected area. There is no species in the area qualifying the project area as Critical Habitat. The protected area is a natural habitat for wildlife having core zone deep inside the protected fragmented by physical barriers, restricting wildlife movement towards road alignment.

292. Mitigation measures. To minimize negative impacts on ecologically important features in the project area the following should be followed:

• If any wild animal (except birds) come within the vicinity of 100m from the construction site, construction works must immediately stop and resume only after the wild animals have moved away. • Employment agreements should specify heavy penalties for illegal hunting, fishing, trapping and wildlife trading (as per Wildlife Act 1972)– all other ancillary works should also agree not to participate in such activities.

108

• Strict anti-poaching surveillance measures will be implemented, especially during project construction phase. • Use only existing licensed quarries for sourcing aggregates. Further, any newly- established quarries – whether inside or outside of rivers and streams – have potential to clear Natural Habitat. These risks can be simply and effectively avoided by sourcing of all aggregates only from existing licensed quarries outside of rivers and streams. • Avoid borrow pits in areas of Natural Habitat (Water reservoir/Stream) and within 200 m of waterways. No borrow pits will be allowed at least 200 m next to waterways. This will help avoid risks of runoff and sedimentation impacting aquatic Habitat. Further, to avoid additional Project impacts on Natural Habitat, no borrow pits will be established in areas of Natural Habitat. • Installation of speed limits caution boards and speed breakers at identified location, informatory boards for road users

293. Residual impact. Considering the above measures, the project road meets the requirements of para 28 (page 35) of the SPS – no measurable adverse impacts, no reduction in population of threatened species etc. Hence, the project works will be in compliance with the SPS and residual impacts on wildlife are expected to be insignificant.

Operation stage – positive impact

294. If the habitat improvement activities described above are implemented as planned an overall positive impact of more sustainable use of natural resources and improvement of forests is expected inside the sanctuary.

F. Impacts on Social Environment

295. The sensitive location such as places of worship, school, college and hospital along project road within 100 meters from the edge of the existing road has been identified as given in Table 33. These structures are projected to be unaffected by the proposed improvement proposal. Short term impacts during the construction stage are expected. Measures such as timely scheduling of construction activities in these areas, provision of sign boards, appropriate barriers such as planting trees and / or raised boundary walls are adopted to minimize impacts.

1. Private land and buildings

Design and pre-construction stage – moderate negative impact

296. Impact: There will be 18.0182ha of land acquisition for the project road as the proposed widening will be accommodated mostly within existing ROW. Community impacts are mostly due to the resettlement of people due to widening of the project road to 2 lanes. There will be dismantling of 740 structures and 89 common property. It was noted that the relocation of structures will be required at congested locations along the project road. The widening options have been devised to minimize impacts of structures.

297. Mitigation Measures: A resettlement plan is prepared to address this issue. The affected people will be compensated and rehabilitated as per the provisions of the Resettlement Plan. 109

298. Residual Impact: Since any foreseen impact on private land and buildings will be addressed in a separate resettlement plan no residual impacts are envisaged.

Construction stage –minor negative impact

299. Impact: At certain locations on the road, particularly at bridge/culvert sites, traffic will be temporarily diverted from the existing carriageway while construction is in progress and temporary traffic diversions will be managed within the ROW. In other instances, traffic may have to be diverted across adjacent private land.

300. Mitigation Measures: In case private land is temporarily used during construction compensation will be paid for any loss of crops or the replacement of damaged structures. Most construction will be undertaken during the dry season when few crops are planted. Losses should be minimized during construction. After completion of the construction works the used land will be reinstated to the state it had before commencement of the works. Access to adjacent properties and agricultural land will be maintained, as necessary. Any damage to areas and infrastructure outside the agreed work sites (Corridor of Impact assessed in project RP) will be restored to pre-construction conditions and will be subject to compensation at contractor cost and through written agreement with the land owner, as applicable.

301. Residual Impact: With adequate compensation for any damages resulting from using private land during construction no residual impacts are to be expected from construction.

Operation stage – neutral impact

302. The likely impacts on land use and settlement patterns are limited. Improved access will lead to increased migration, but this will occur gradually and over a prolonged period. There will be time for expansion of residential areas to be established. However, there will be a need to control ribbon development.

2. Public infrastructure and utility structures

Design and pre-construction stage – minor negative impact

303. Impact: On the project road, utilities interfere with the ROW at few locations that will have to be shifted / removed prior to construction.

304. Mitigation Measures. Before construction commences a detailed survey has to be carried out in order to list all utilities that will interfere with the road works. These utilities will have to be shifted before the works in close cooperation with the respective owners of the utilities.

305. Residual impact. With proper preparation no residual impacts are to be expected.

Construction stage – minor negative impact

306. Impact. Traffic may experience minor delays when diverted around active construction areas but will be more severely hampered at the locations where temporary road closures are necessary. There are also likely impacts on communities from the construction activities.

110

307. Mitigation measures. Such hazard points will have proper signs indicating the nature of the problem envisaged. Contractor will ensure that information on the timing of construction works and notifications of road closure (if any) is provided via the local media (radio, TV, newspaper etc.) or through the local community heads.

308. Residual impact. With the proper implementation of the proposed mitigation measures the construction of the project is not expected to have a residual impact on public utilities. However some temporary negative impact on traffic flow will be unavoidable.

Operation stage – neutral impact

309. During the operation stage of the project no impact on public infrastructure and utilities is expected.

3. Noise and disturbance

Design and pre-construction stage – minor negative impact

310. Impact. The ambient noise level throughout the road section exceeds the standards for residential areas except at some locations. During the construction period, noise will be generated from the operation of heavy machinery, the haulage of construction materials to the construction yard and the general activities at the yard itself. Concrete mixing and material movements will be the primary noise generating activities and will be uniformly distributed over the entire construction period. These construction activities are expected to produce noise levels in the range of 80-95 dB(A) at a distance of about 5m from the source. Cost of standard solid (concrete) noise barriers have been included in the bid documents for sensitive receptors identified during detailed project report preparation.

311. The noise generating equipment used in construction activities is also regulated under Noise Pollution (Regulation and Control) Rules 2000 and may cause concern among local villagers. The range of typical noise levels in relation to distance from a construction site is shown in Table 50.

Table 50: Construction Noise / Distance Relationship Distance from Construction Site (m) Range of typical Noise Level dB(A) 8 82-102 15 75-95 30 69-89 61 63-83 91 59-79 122 57-77 152 55-75 305 49-69 Source: Department of Transportation, State of Wisconsin (USA)

312. Noise and vibration from piling (if used at bridge locations) will be unavoidable, but the impact will only be temporary and affect people living or working near piling locations, if involved at location of bridge constructions. The impact and sources of noise are summarized in Table 51.

Table 51: Likely Impact on Noise Quality in the Vicinity of Project Area 111

Impact Source Increased noise levels • Mobilization of heavy construction machinery; causing discomfort to • Accelerations/ decelerations/ gear changes – though the local residents, workers extent of impact will depend on the level of congestion and smoothness of the road surface; and local fauna • Excavation work for foundations and grading; • Construction of structures and other facilities; • Crushing plants, asphalt production plants; and loading, transportation and unloading of construction materials.

313. Typical noise levels associated with various construction activities and equipment are presented in Table 52.

Table 52: Typical Noise Levels of Principal Construction Equipment (Noise Level in dB (A) at 50 Feet) Clearing Structure Construction Bulldozer 80 Crane 75-77 Front end loader 72-84 Welding generator 71-82 Jack hammer 81-98 Concrete mixer 74-88 Crane with ball 75-87 Concrete pump 81-84 Concrete vibrator 76 Excavation and Earth Moving Air compressor 74-87 Bulldozer 80 Pneumatic tools 81-98 Backhoe 72-93 Bulldozer 80 Front end loader 72-84 Cement and dump trucks 83-94 Dump truck 83-94 Front end loader 72-84 Jack hammer 81-98 Dump truck 83-94 Scraper 80-93 Paver 86-88 Grading and Compaction Landscaping and clean-up Grader 80-93 Bulldozer 80 Roller 73-75 Backhoe 72-93 Truck 83-94 Paving Front and end loader 72-84 Paver 86-88 Dump truck 83-94 Truck 83-94 Paver 86-88 Tamper 74-77 Dump truck 83-94 Source: U.S. Environmental Protection Agency, noise from Construction Equipment and Operations. Building Equipment and Home Appliance. NJID. 300.1.December 31, 1971

314. Mitigation Measures. By using noise reduction equipment, the hindrance from construction equipment can be minimized. By planning noise generating activities during daytime only hindrance to local residents can be minimized. At sensitive locations such as schools, colleges and hospitals along the project road noise barrier shall need to be provided.

112

315. Residual Impact. With the proper implementation of mitigation measures the project design is not expected to have minimal residual impact.

Construction stage - moderate negative impact

316. Impact. The noise levels indicated for various construction activities/equipment, while far exceeding permissible standards of CPCB and IFC EHS for residential areas, will occur only intermittently. Still, these extremely high sound levels present real risk to the health of workers on- site.

317. The construction activities are introduced in Noise Pollution Rules, 2000 with its amendment in 2017. The maximum limit for noise near the construction site is 75 dB (A) Leq (5 min) in industrial areas and to 65 dB (A) Leq (5 min) in residential and other areas. There are sensitive receptors identified within 50m from the centre line along the proposed project road as given in Table-33. The noise (existing noise and construction noise) levels during construction is predicted higher than the National Ambient Noise Standards (CPCB limits) and IFC EHS standards as ambient noise level exceeds the limits. As a best construction practices necessary mitigation measures are proposed during each phase of construction activity.

318. During construction, varying degree of noise impacts are likely to be felt by the communities of main settlements i.e. Thiruvalluvar nagar, New Agraharam, Ammachatram, Umamaheswarapuram, Thirubhuvanam, Thiruvidaimaruthur, Govindapuram, Aduthurai, Thyagarajapuram, Narsasingampettai, Thiruvalangudi, Sivaramapuram Agraharam, Kathirmangalam, Gunathalaipadi, Kambar colony, Senniayanallur, Aryapuram, Malliyam, Solasakranallur, Athukudi, Dharmanathapuram, Sirkazhi and other small settlements along the project road. Although temporary in nature, the construction noise will affect the most communities living close to the construction zone. However, the above listed sensitive receptors will be especially impacted due to increase in noise levels as these would be near the construction site. Although temporary in nature, the construction noise will affect the most communities living close to the construction zone.

319. Mitigation measures. In construction sites within 500 meters of a settlement, noisy operations should cease between 22:00 and 06:00 hrs. Regular maintenance of construction vehicles and machinery must also be undertaken to reduce noise.

320. Timely scheduling of construction activities, proper maintenance of construction machineries, use of personnel protective equipment, etc. will minimize these impacts.

321. Noise impacts are an unavoidable consequence of construction that should be mitigated by limiting the times of construction to daylight hours (8am-5pm) in the vicinity of sensitive receptors. Further to minimize noise impacts near sensitive receptors (particularly schools), operation of excavator and other heavy machineries will be carried out mostly during off-hours (7 am to 9 am and 3.30 pm to 7 pm) and on holidays (Saturday and Sundays). The schedule will be prepared/modified in consultation with the community and relevant local authorities. Baseline noise will be established for all sensitive areas prior to construction and follow up noise monitoring will be carried out during the construction.

322. Implementation of suitable mitigation measures will reduce the construction noise to acceptable limits. Mitigation measures should include:

• Installations of noise barriers; 113

• construction machinery should be located away from settlements. If noise levels exceed the prescribed Leq, suitable mitigation measures like using additional silencers in noise generating equipment; erecting additional noise barriers and the use of proper PPEs shall be implemented; • Construction machinery and equipment must properly maintained and designed with built-in silencers, mufflers and enclosures. This will reduce the noise by 5 to 10 dB(A); • careful planning of machinery operation and the scheduling of such operations, no idling of machinery; • controlled blasting should only be carried out with prior approval from the Engineer in charge; and • contractors should be required to fit noise shields on construction machinery and to provide earplugs to the operators of heavy machines.

323. Residual Impact: With the proper implementation of the proposed mitigation measures the project construction is not expected to have any significant residual impact.

Operation stage – moderate impact

324. The current low traffic flows along the project road is expected to increase because of improved economic activities associated with better access. The larger numbers of vehicles will be an additional source of noise and gaseous emissions.

325. Federal Highway Administration's Traffic Noise Model (FHWA TNM) helps for highway traffic noise prediction and analysis. Detailed analysis is presented in Appendix-13. TNM computes highway traffic noise at nearby receivers. As sources of noise, it includes noise emission levels for the following vehicle types:

• Automobiles: all vehicles with two axles and four tires -- primarily designed to carry nine or fewer people (passenger cars, vans) or cargo (vans, light trucks) -- generally with gross vehicle weight less than 4,500 kg (9,900 lb); • Medium trucks: all cargo vehicles with two axles and six tires - generally with gross vehicle weight between 4,500 kg (9,900 lb) and 12,000 kg (26,400 lb); • Heavy trucks: all cargo vehicles with three or more axles -- generally with gross vehicle weight more than 12,000 kg (26,400 lb); • Buses: all vehicles designed to carry more than nine passengers; and • Motorcycles: all vehicles with two or three tires and an open-air driver / passenger compartment.

326. The procedure for prediction of noise levels involves the following steps:

a. Identification of various receivers, b. Determination of land uses and activities which may be affected by the noise generated, c. Assemble input parameters, and d. Application of the model.

327. The description of the components to predict noise level are as follows:

• Receivers: TNM calculates the sound levels at the input receivers.

114

• Land Uses: Land use along the road is obtained from the topographic drawings. This information provides the range of shielding and absorption factors to be applied at the various receivers. • Input Parameters: Traffic volume for the projected period is obtained from the traffic projections. The total number of vehicles passing per hour by type - light, medium and heavy along with their average speed is used for predictions. • Average Noise Level: All vehicles produce noise, which is taken as the base, and the cumulative noise at the receiver distance due to the whole traffic is estimated. The average noise level varies depending on the type of vehicle. • Application of Model: Equivalent noise levels due to traffic at the receivers are estimated using Federal Highway Noise model. Equivalent Sound Level (TEQ, denoted by the symbol, LAeqT): Ten times the base-10 logarithm of the square of the ratio of time-average, mean-square, instantaneous A-weighted sound pressure, during a stated time interval, T (where T=t2-t1), and the reference mean-square sound pressure of 20: Pa, the threshold of human hearing, e.g., 1HEQ, denoted by the symbol, LAeq1H, represents the hourly equivalent sound level.

LAeqT = LAE - 10*log10(t2-t1) where LAE = Sound exposure level in dB

328. Sound Exposure Level (SEL, denoted by the symbol, LAE): Over a stated time interval, T (where T=t2-t1), ten times the base-10 logarithm of the ratio of a given time integral of squared instantaneous A-weighted sound pressure, and the product of the reference sound pressure of 20:Pa, the threshold of human hearing, and the reference duration of 1 sec. The time interval, T, must be long enough to include a majority of the sound source’s acoustic energy. As a minimum, this interval should encompass the 10 dB down points. The traffic data considered for Noise level predictions is presented in table 53 and equivalent observed noise levels from field monitoring is shown in Table 54.

329. The IFC Environmental Health and Safety Guidelines – “General EHS Guidelines (Environmental Noise Management”) and the World Health Organization (WHO, 1999) states that noise levels from a project should not result in a maximum increase in background levels of 3 dB(A) at the nearest receptor location off-site.

330. The Indian standard requires noise levels for the 12 hour Leq-dB(A) not to exceed 65 dB(A) and 55 dB(A) at commercial building during the daytime and at nighttime respectively. This is also the IFC standard. Indian standards require noise levels for the 12 hour Leq-dB(A) not to exceed 55dB(A) in daytime and not to exceed 45dB(A) nighttime at residential property.

331. From Table 55, it is observed that predicted noise levels (Leq) near the receivers within 20m from the centre line of the road are found to be within permissible limit of 3 dB(A) during day time. However, the predicted noise levels are found to be higher than desired levels during night time from 50m of centerline for night time for the respective landuse categories. The baseline noise levels (2019) are already higher than the permissible limits of CPCB for different landuse categories for day and night. The predicted levels show increase in noise levels for future years at all receivers considering increase in traffic volume. The incremental noise levels for future years exceeds the allowable limit of 3 dB (A) during night time from the baseline levels. Mitigation measures suggested in EMP such as installation of noise barriers should be adopted for the sensitive receptors falling within 50 m center line of the road corridor. The detailed noise assessment and prediction is presented in Appendix -13.

4. Vibration

Design and pre-construction stage – neutral impact

332. Existing ambient vibration levels at the sensitive receptors are low. Any impact on structures by means of vibration will be generated during the construction phase of the project, regardless of the design chosen.

Construction stage –moderate negative impact

333. When the ground is subject to vibratory excitation from a vibratory source, a disturbance propagates away from the vibration source. The ground vibration waves created are similar to those that propagate in water when a stone is dropped into the water. The duration and amplitude of vibration generated by construction equipment varies widely depending on the type of equipment and the purpose for which it is being used. The vibration from blasting has a high amplitude and short duration, whereas vibration from grading is lower in amplitude but longer in

116

duration. In assessing vibration from construction equipment, it is useful to categorize the equipment by the nature of the vibration generated.

334. Review of available literature indicates that there is limited information available on vibration source levels from general construction equipment. The most comprehensive list of vibration source amplitudes is provided in the document entitled Transit Noise and Vibration Impact Assessment (Federal Transit Administration 2006).

Table 56: Vibration Generated from Different Construction Equipment Equipment Reference PPV at 25 ft. (in/sec) Vibratory Roller 0.21 Large Bulldozer 0.089 Caisson Drilling 0.089 Loaded Trucks 0.076 Jackhammer 0.035 Small Bulldozer 0.003 Sources: Federal Transit Administration 2006 (except Hanson 20016 for vibratory rollers)

335. Using these source vibration levels, vibration from these equipment can be estimated by the following formula:

n PPVEquipment =PPVRef (25/D) (in/sec)

Where: PPVRef = reference PPV at 25 ft. D = distance from equipment to the receiver in ft. n = 1.1, attenuation rate(7)

336. International Guidelines and Standards present criteria for vibration related building damage in the form of threshold levels of vibration (peak particle velocity), as either a value or range of values. Key factors in determining these levels are as follows:

• the nature of the building including its construction, its condition, and whether is of historic importance; • the likely extent of damage i.e. cosmetic, minor structural or major structural; and • whether the source of vibration is continuous or a single event and the dominant frequency (Hz).

337. Impact. The values of vibration generated from the operation of various equipment in construction of project road are below the threshold ppv (mm/s) as mentioned in Table-55. However, vibration during construction may induce cracks and damages to structure next to road alignment particularly overhead water storage tanks and identified buildings or sensitive receptors.

338. Mitigation Measures. For the structures within 4.5 m (as vibration impacts from construction equipment’s beyond this limit will be insignificant) from road edge, suitable mitigation measures should be adopted to minimize the vibration levels. In case any structure is weak, a pre-construction survey of the building shall be done in detail by the Contractor, witnessed by the CSC as well as the property owner. Vibration monitoring will be carried out at weak structures during construction and additional mitigation measures will be installed in case measured vibration levels (peak particle velocity) exceed 3 mm/s for very sensitive buildings or 5 mm/s for residential structures per DIN 4150-3 threshold. Signed documents and photographic records will be kept as evidence to protect both the owner as well as the project from spurious claims.

339. A wave barrier is typically a trench, or a thin wall made of sheet piles or similar structural members. The purpose of a barrier is to reflect or absorb wave energy, thereby reducing the propagation of energy between a source and a receiver. The depth and width of a wave barrier must be proportioned to the wavelength of the wave intended for screening.

340. Adverse human response to construction vibration can be mitigated by good communication between the contractor and local residents. If occupiers of dwellings are informed of their nature, duration, and potential vibration effects prior to the works, then adverse response will be less. Generally, the main concern relating to construction vibration is of damage to property and if this is not likely to occur, then this point should be made clear to residents.

341. Residual Impact: With the proper implementation of the proposed mitigation measures the construction of the project is not expected to have a residual impact due to vibration.

118

Operation stage – minor negative impact

342. Impact. Because vehicles travelling on highway are supported on flexible suspension systems and pneumatic tires, these vehicles are not an efficient source of ground vibration. They can, however, impart vibration into the ground when they roll over pavement that is not smooth. Continuous traffic travelling on a smooth highway creates a fairly continuous but relatively low level of vibration. Where discontinuities exist in the pavement, heavy truck passages can be the primary source of localized, intermittent vibration peaks. These peaks typically last no more than a few seconds and often for only a fraction of a second. Because vibration drops off rapidly with distance, there is rarely a cumulative increase in ground vibration from the presence of multiple trucks. In general, more trucks result in more vibration peaks, though not necessarily higher peaks. Automobile traffic normally generates vibration amplitudes that are one-fifth to one-tenth the amplitude of truck vibration amplitudes. Accordingly, ground vibration generated by automobile traffic is usually overshadowed by vibration from heavy trucks.

343. Mitigation Measures: Because vibration from vehicle operations is almost always the result of pavement discontinuities, the solution is to smoothen the pavement to eliminate the discontinuities. This step will eliminate perceptible vibration from vehicle operations in virtually all cases.

344. Residual impact: The impact of vibrations due to road traffic will be negligible given the highway pavement is maintained at good condition.

5. Occupational health and safety

Design and pre-construction stage – neutral impact

345. No impacts on occupational health and safety are expected to arise from the design phase of the project. Road design proposed standards are consistent with the parameters recommended in the relevant standards of the IRC and are detailed in Chapter III of this report.

Construction stage - moderate negative impact

346. Impact. Transportation incidents accounted for majority of fatal roadway worksite incidents.8 In India, Tamil Nadu has recorded the highest rate of road accident fatalities at 23 fatalities/lakh persons. 9 As such, particular attention to transportation-related work hazards should be given under the project. Among other construction-related risks in highway projects are:

• falls and slips due to uneven surfaces, edges of elevated ground with no proper barricading; • struck-bys falling debris or flying objects; • caught-in-betweens due to rotating equipment or unguarded parts of construction machinery; and • electrocution risks while carrying out work or residing in campsites

8 https://www.dbkrieginc.com/onsite-work-safety.php; data taken from US Bureau of Labor Statistics 9 Policy Research Studies (PRS) Legislative Research, India. https://www.prsindia.org/policy/vital-stats/overview-road- accidents-india 119

347. The construction camps are anticipated to house up to 200 people for about two years. With this concentration of people, the potential for the transmission of diseases and illnesses will increase. The main health and safety risks during construction will arise from:

• inadequate sanitation facilities in worker camps; • introduction of sexually transmitted, and other diseases, by immigrant workers; and • outbreaks of malaria, typhoid, cholera etc. amongst the labour force; and given the current COVID-19 pandemic there is also a risk of construction workers being exposed to this and other communicable viral diseases, particularly given construction is directly within the community and the transient nature of the construction workforce.

348. Mitigation Measures. The following shall be followed before, during, and after construction activities, as applicable:

• The Contractor will be required to conduct workplace risk assessment to identify potential risks to workers. • The Health and Safety Officer shall also conduct regular training on health and safety. • The contractor is responsible for instituting measures and procedures to maintain cleanliness and order in campsites and construction sites. • The Contractor will provide facilities such as dust bins and collectors for the temporary storage of all waste. This waste should be adequately stored to avoid pollution of water supplies and water sources and to avoid dust formation. • The Contractor will be responsible for the safe removal and/or storage of all waste in order to prevent environmental pollution of any type that may be harmful to people or animals. • All necessary safeguards should be taken to ensure the safety, welfare and good health of all persons entitled to be on the sites and to ensure that works are carried out in a safe and efficient manner. • All personnel working at vulnerable site locations will wear safety helmets and strong footwear (OSHA recommended PPE). • It should be ensured that all workmen and staff employed on site use proper safety equipment – for example, eye protectors, ear plugs, safety helmets, the designated safety equipment when working over water – and that proper rescue equipment is available. • Fire extinguishers and first-aid equipment will be kept at all sites. • Additional health and safety protocols for prevention and control of the spread of COVID 19 and other communicable diseases shall be put in place in accordance with local/national guidelines and international best practices. • To ensure safe construction, lighting devices and safety signals shall be installed and traffic rules and regulations to be strictly followed. • The electrical equipment should be checked regularly to avoid risks to workers. Adhere to strict schedule for completion of road works and avoid prolonged construction and disturbance. • Implement SEMP Sub-plans (e.g. Health and Safety Plan, Traffic and Road Management Plan, Camp Management Plan). • Provide barricade fencing to mitigate trespassing. • Provide barricade to temporarily enclose open excavated slopes / foundations.

120

• Provide sufficient lights, clear warning signs and danger signals. • Assign security personnel to prevent accidents. • Warning signs and cones will be installed in and around the work site and along haul roads, with clearly marked danger zones. • Safety flags and flag persons will be used, as needed. • Record of incidents /accidents / near-miss/ fatalities associated with the project will be maintained. • Records of issues raised will be maintained in accordance with the project GRM. • Outreach to local communities and information disseminate e.g. on project implementation schedule, health & safety and ERPs will be provided via information disclosure and meaningful consultation activities) in local language in the project area of influence.

349. The following actions will be undertaken at construction camps and stipulated in construction contracts:

• submit and obtain approval for a health and safety plan prior to the commencement of work; • provision of adequate health care facilities and healthcare staff; • ensure adequate security is provided to construction staff on site and at worker accommodation; • workers will be required to undergo pre-employment medical screening and treatment (if required) and periodic health checks thereafter; and • For COVID-19 related health and safety risk, the contractor will be required to prepare and implement a COVID-19 Action Plan10.

350. The project will support a public health education programme for workers and villagers covering road safety, malaria, hygiene, endemic and communicable diseases such as COVID- 19 and sexually transmitted diseases. The district health departments will also be invited to participate in monitoring and educating communities and workers affected by the project.

351. Residual Impact. With proper implementation of the proposed mitigation measures the residual impact on occupational health and safety is expected to be low.

Operation stage – neutral impact

352. No impact on occupational health and safety is envisaged during operation phase of the project. Road safety features are included in the project design as discussed in Chapter III of this report.

6. Community health and safety and local resources

Design and pre-construction stage – neutral impact

10For COVID-19 national restrictions for containing the spread of COVID-19 must be complied with and in developing the health and safety management plan Government of India (https://www.mygov.in/covid-19) and World Health Organization guidance (https://www.who.int/emergencies/diseases/novel-coronavirus-2019/technical-guidance) should be followed ensuring adequate sanitation and welfare facilities including for hand washing and personal protective equipment are provided to construction workers. Given the specialist nature of responding to COVID-19 public health officials/experts to be consulted.

121

353. No impacts on community health and safety are expected to derive from the design phase of the project. Improving overall safety during operation is a major consideration in the design of the road. Road safety features are included in the project design as discussed in Chapter III of this report.

Construction stage –moderate negative impact

354. Impact: Construction camps may put stress on local resources and the infrastructure in nearby communities resulting to people raising grievances. This sometimes leads to conflict between residents and migrant workers. The construction activities may also potentially result in adverse impacts to community health and safety such as construction traffic and accidents, and accidental spills of liquid materials. There are also chances of exposure to communicable diseases from migrant workers.

355. Mitigation Measures: To prevent problems between construction workers and the local communities, the contractor should provide the construction camps with facilities such as health care clinics, places of worship, and occasional entertainment. During construction, benefits to local people can be maximized if the contractor recruit construction workers locally regardless of gender. Contractor should also not discriminate in the employment of women. The contractor will be required to develop a community health and safety plan which will also include emergency response and preparedness procedures.

356. The project will support a public health education programme for workers and villagers covering road safety, hygiene, malaria and other endemic diseases, and communicable diseases such as COVID-19 and sexually transmitted diseases. The district health departments will also be invited to participate in monitoring and educating communities and workers affected by the project.

357. Residual impact. With proper implementation of the proposed mitigation measures no residual impact is expected on the community health and safety.

Operation stage – moderate negative and positive impact

358. Impacts and Mitigation: The improvements of the project road are expected to benefit the socio-economic conditions of communities in and around the project area. Improved access and reduced travel time and cost will be major stimuli to economic growth, health and education, particularly in rural areas. Better access of agricultural goods to market will be important and a major contributor to poverty reduction. These benefits are likely to have a positive impact on community health. Some risks associated with improved road such as accidents etc. are however anticipated. Implementation of road safety measures will minimize these risks. Section 10 under Design Standards of Chapter III deals with traffic safety features, road furniture, road markings and other facilities which shall contribute to increased safety, not only for vehicles but also pedestrians and other road users. Geometric and sight distance improvement considered in the road designs used during bidding are also meant to improve fundamental features of the road to increase safety.

G. Physical and Cultural Resources

359. There are no adverse impacts anticipated on historical places/monuments. However, there are small shrines along the road. Care must be taken to clearly identify these structures

122

before construction and avoid any damage to these structures. If necessary, these structures maybe moved after carrying out proper consultation with the local community people. Earthworks, as associated with the road construction/improvement works, or deriving from secondary sites such as quarries or borrow pits, may reveal sites or artefacts of cultural/archaeological significance. In the event of such discovery, the concerned authorities should be informed and the requirement to take such action should be incorporated in contract documents.

H. Induced and Cumulative Impacts

360. According to the ADB Environment Safeguards Sourcebook Cumulative Impacts is described as: “The combination of multiple impacts from existing projects, the proposed project, and anticipated future projects that may result in significant adverse and/or beneficial impacts that cannot be expected in the case of a stand-alone project.” The sourcebook also describes Induced Impacts as: “Adverse and/or beneficial impacts on areas and communities from unintended but predictable developments caused by a project, which may occur at later or at a different location.

361. The road upgrading will improve the travel speed and travel condition along the project road corridor and is expected to generate a road user cost saving and this will result in additional traffic generation along the corridor. Currently there is no other information on future development projects along the project road. Hence, it is difficult to assess other cumulative impacts from other projects which may get implemented in the project area.

362. The improved road is expected to increase transport through the project region but is unlikely to trigger exponential development in this region. Setting up few new industries and increase in trade volume though cannot be ruled out. Noise and air quality impacts due to increased traffic volume are also envisaged. Mitigation measures are available for noise impacts while air quality impacts are considered insignificant. As such no significant induced environmental impact is anticipated due to proposed project activity.

I. Expected Benefits from the Project

363. The immediate benefits of road construction and improvement will come in the form of direct employment opportunities during construction for the roadside communities engaged as wage laborer, petty contractors and suppliers of raw materials. During operation stage, roadside economic activities supporting transport like gasoline stations, automotive repair shops, lodging, and restaurants will increase due to increased number of vehicles. The project road section is part of connecting industrial zones to enhance transportation services for raw material and products. Increase in agro-industrial activities are also expected to take advantage of improved access to urban centers where there are higher demands and better prices for agricultural products. Project will accelerate the economic opportunities resulting in reduced migration. Other benefits of project road improvement are: (i) reduction in travel time, (ii) better mode and frequency of transport, (iii) access to quality health care, educational, and other infrastructural facilities (iv) improved quality of life of rural population, and (v) better investment climate for industries creating more employment opportunities for local people.

123

VII. CONSULTATION, PARTICIPATION AND INFORMATION DISCLOSURE

A. Meaningful Consultation

364. In accordance with ADB’s Safeguard Policy Statement (SPS) 2009 meaningful consultations were held early and throughout the project development stages to allow the incorporation of relevant views of the stakeholders in the final project design, mitigation measures, implementation issues, and enhance the distribution of benefits. All the five principles of information dissemination, information solicitation, integration, co-ordination, and engagement into dialogue were incorporated in the consultation process. The analysis of environmental impacts from the project was strengthened and modified based on opinions of all those consulted, especially in the micro level by setting up dialogues with the village people from whom information on site facts and prevailing conditions were collected. The requirement of public consultation during the implementation of the project has been proposed as part of the mitigation plan.

B. Objectives of the Consultations

365. Stakeholder’s consultations were held with intent to understand their concerns, apprehensions, overall opinion and solicit recommendations to improve project design and implementation. Informal meetings, interviews were organized covering the entire projects design stage. Consultations provide affected people a platform to ensure incorporation of their concerns in the decision making process and foster co-operation among officers of CKICP, the community and the stakeholders to achieve a cordial working relationship for smooth implementation of the projects. It inculcates the sense of belongingness in the public about the project.

366. The discussions were designed to receive maximum inputs from the participants regarding their acceptability and environmental concerns arising out of the project. They were given the brief outline of the projects to which their opinions were requested particularly in identifying and mitigating any potential adverse impact.

C. Methodology for Consultations

367. Consultation with the stakeholders, beneficiaries, and community leaders were carried out using standard structured questionnaires as well as unstructured questionnaires. Questionnaire survey/ discussions were designed to obtain background information and details of general environmental issues that concern people in the project areas. In addition, environmental issues were discussed with relevant organizations, government officials, beneficiaries, community leaders and experts. Aside from these, personal discussions with officials, on site discussion with affected stakeholders, and reconnaissance visits have also been made to the project areas. Public consultation has been carried out at three locations along the project road section during initial surveys.

368. In total over 3 consultation session were organized along SH-64 project road. Table 58 show the details of the public consultations carried out along various road sections.The public consultation meetings were organized during months of January 2016 and July 2020 at Kumbakonam (km 3+500) and Vaitheeswaran Koil (km 48+000) and Mayiladuthurai to disseminate the information regarding widening and strengthening of road SH-64, respectively

124

by the officers of Highways Department, Government of Tamil Nadu and staff of DPR consultant.

369. A total of192 participants including 172 males and 20 females attended the public consultation meetings. The community consultation with locals were organized with prior information and details of place and timing after permission from district authorities. The fixed venue for consultation was sanitized with the help of concerned area health care service office. The social distancing during consultation and other facilities including temperature check, hand sanitizer and use of mask was made mandatory for all the participants. Table 58 show the details of the public consultations carried out along various road sections.

1. Project Stakeholders

370. All types of stakeholders were identified to ensure as wide coverage as possible.

• Residents, shopkeepers and business people who live and work along the road specially the project affected persons • All type of road users/commuters • Executing Agency, Construction Supervision Consultant and Implementing NGOs • Other government institutions whose remit includes areas or issues affected by the project (state environment and forest department, Pollution Control Board (PCB), Irrigation Department, Public Health Engineering (PHED) Department; and • The beneficiary community in general.

2. Consultation with Government Departments

371. Various officials consulted during IEE preparation included State Forest Department, Department of Science Technology and Environment, Urban Development and Tamil Nadu State pollution control board for air, noise and water quality information, IMD for the climatic data, statistical officer for population and demographic profile, panchayat department for village level information, Survey of India for the toposheet requirement, revenue department for the land record information, PHED officers for hand pump relocation and quality assessment, state electricity board offices for electric pole shifting etc.

372. These departments helped to provide various project related data and information which helped preparation of reports and data analysis.

3. Consultation with Local People and Beneficiaries

373. The informal consultation generally started with explaining the projects, followed by an explanation to potential impacts. Participant’s views were gathered with regard to all aspects of 125

the environment which may have direct or indirect impact on local people. Key issues discussed were: • Awareness and extent of the project and development components; • Benefits of the project for the economic and social upliftment of community; • Labour availability in the project area or requirement of outside labour involvement; • Local disturbances due to project construction work; • Necessity of tree felling etc. at project sites; • Impact on water bodies, water logging and drainage problem if any; • Environment and health aspects; • Flora and fauna of the project areas; and • Socio-economic standing of the local people.

374. The project has immense acceptability among the local people. They perceive that in addition to providing all weather connectivity, the project road will bring positive socioeconomic changes in the areas. Local people mainly discussed on the issues related to flooding, rehabilitation, resettlement, and road safety issues. The outcome of the consultations have been summarized in Table 59.

376. Most of the people interviewed were well aware of the environmental conditions in and around their villages. A major percentage are not aware of any foreseen deterioration in the air and noise quality due to expansion of existing highway. The villagers are quite enthusiastic about the proposed project as it will give fillip to rural economy and present them many employment opportunities during construction of project road. Overall positive approach towards the project is observed.

4. Results of Consultation with Local People

377. Most of the people interviewed strongly support the project work. The people living in the entire project area expect the different project elements to facilitate transport, employment, tourism, boost economic development and thereby provide direct, or indirect, benefits to them. In order to access the existing environment and likely impacts on surrounding population, an interview survey was carried out. A priority of the population was interviewed through a designed questionnaire. Precaution has been exercised during the survey to ensure that the priority interviewed is truly representative of the affected groups and the questions are worded so as not to generate a bias response. 129

378. Overall, most of the people interviewed strongly support the project. The people living in the entire project area expect the different project elements to facilitate transport, employment, tourism, boost economic development and thereby provide direct, or indirect, benefits to them. Construction camps may, however, put stress on local resources and the infrastructure in nearby communities. In addition, local people raised construction-process related grievances with the workers. This sometimes leads to aggression between residents and migrant workers. To prevent such problems, the contractor should provide the construction camps with facilities such as proper housing, health care clinics, proper drinking water and timely payment. The use of local laborers during the construction will, of course, increase benefits to local peoples and minimise these problems. Wherever possible, such people should be employed.

379. Design considerations have been made to incorporate most of the suggestions and demands of the local people except those which are beyond the scope of the project like improvement of already deteriorated water quality, drinking water facility and reconstruction of link roads, etc.

D. Interaction with NGOs

380. In order to get independent views on the likely impacts of the project, non-government organizations at local as well asregional level were consulted during the IEE process. Aspects such as conservation activities, presence of flora and fauna, likely project impacts and possible mitigation measures were discussed and views and suggestions from these NGO’s were incorporated in the EMP. Consultation will continue with these NGO’s during project implementation and operation.

E. Public Disclosure and Further Consultations

381. The TNICP will be responsible for the disclosure of this IEE in compliance to ADB’s Access to Information Policy 2019 and ADB’s SPS 2009. The IEE will be disclosed in the English language in the office of TNICP. The report will also be made available to interested parties on request from the office of the TNICP. Since this is Category B project, this IEE report will be disclosed to the public through the ADB website. This IEE report will also be made available to all stakeholders as part of the consultation process required under the SPS 2009.

382. Prior to finalization of detailed engineering design, the contractor, with the assistance of the PIU should consult affected persons along sensitive receptors identified during survey on structural and institutional mitigation measures for impacts such as, but not limited to, noise. Further, project consultations will be organized by the FIU in coordination with CSC and with the presence of representatives from the contractor. Participation of women and FGDs with women and vulnerable groups will be prioritized and conducted to the extent feasible. These should be done at least quarterly during construction period.

VIII. GRIEVANCE REDRESS MECHANISM

383. Project grievance redress mechanism (GRM) will be established to evaluate and facilitate the resolution of affected persons concerns, complaints, and grievances related to social and environmental issues of the project. The GRM will provide a time-bound and transparent mechanism to voice and resolve social and environmental concerns linked to the project.

384. GRM Information: Information on the availability of GRM shall be disclosed to public through the TNICP website and through information boards by TNICP along the project road. The setup GRM shall have the system of records keeping of details such as contact details of complainant, date of the complaint received nature of grievance, etc. for the project road and shall take necessary action to address the complaint. The concerned grievance redress committee (GRC) will determine the merit of each grievance and resolve grievances within an outer time limit of three months of receiving the complaint. All complaints determined to be within the purview of land acquisition, rehabilitation and resettlement will be dealt with under the LARR GRC detailed in the RPs. Otherwise, all other social and environmental related complaints will be coursed through the grievance redress process detailed below.

385. Grievance redress process: The grievance redress process will be a two-tier process for both LARR and all other project-related complaints. In case of grievances that are immediate and urgent in the perception of the complainant, the contractor and Construction Supervision Consultant (CSC) on-site personnel will provide the most easily accessible or first level of contact for quick resolution of grievances. Contact phone numbers and names of the concerned Divisional Engineer, Assistant Environment Specialist, contractors, and CSC will be posted at all construction sites at visible locations. The PIU safeguard officers will be responsible to see through the process of redressal of each grievance.

(i) 1st Level Grievance: The Regional level Project GRC will be chaired by the concerned Divisional Engineer and would comprise the Assistant Environment Specialist, Project Manager of EPC contractor and Resident Engineer of CSC concerned. The Regional level GRC can immediately resolve relatively simple, on- site concerns and grievances in consultation with each other. Grievances at this level will be addressed within 7 days of receipt of a complaint/grievance. (ii) 2nd Level Grievance: All grievances that cannot be redressed within 7 days at the Regional level will be reviewed by the State level Project GRC. It will serve as appellate authority and will be chaired by the Chief Engineer and will comprise the Superintending Engineer concerned, Environment Specialist, Team Leader of CSC concerned, Project Manager from Project Management Services of CSC-01 and Authorized Representative from EPC contractors, as needed. The State level GRC will attempt to resolve them within 3 weeks.

386. Complaints Register with EPC Contractor: The contractor shall keep and maintain a complaint register report at their site office along the project road as well as project facilities like construction camp, labour camp etc., for public to register their complaints. The EPC Contractor, after taking necessary action based on the complaint, will also incorporate the same in the complaint register. This report will also be part of the monthly report, to be submitted to the Regional GRC and for CSC to monitor and take necessary action, if needed. It is to be noted that, inaction upon the complaint of the public will be considered as a major lapse from the side 131

of the EPC contractor, leading to invoking of penalty clause which is given in bid document/EMP.

387. Despite the project GRM, an aggrieved person shall have access to the country's legal system at any stage, and accessing the country's legal system can run parallel to accessing the GRM and is not dependent on the negative outcome of the GRM. The GRCs will continue to function throughout the project duration including the defects liability period. The schematic of the GRM is presented in Figure 17.

IX. ENVIRONMENTAL MANAGEMENT PLAN

A. Introduction

388. The Environmental Management Plan (EMP) is the synthesis of all proposed mitigation and monitoring actions, set to a time-frame with specific responsibility assigned and follow-up actions defined. It contains all the information for the proponent, the contractor and the regulatory agencies to implement the projects within a specified time-frame.

389. This EMP consists of a set of mitigation, monitoring and institutional measures to be taken for the project to avoid, minimize and mitigate adverse environmental impacts and enhance positive impacts. The plan also includes the actions needed for the implementation of these measures. The major components of the Environmental Management Plan are:

• Mitigation of potentially adverse impacts; • Monitoring of EMP implementation during project construction and operation; and • Institutional arrangements to implement the EMP.

390. Prior to start of construction work Environmental Expert of the CSC team in coordination with Contractor will update this EMP to make it site specific in the form of Construction EMP (CEMP).

B. Objectives of Environmental Management Plan

391. The main objectives of this EMP are:

• To ensure compliance with Asian Development Bank’s applicable safeguard policies, and regulatory requirements of the Government of Tamil Nadu and India; • To formulate avoidance, mitigation and compensation measures for anticipated adverse environmental impacts during construction and operation, and ensure that environmentally sound, sustainable and good practices are adopted; • To stipulate monitoring and institutional requirements for ensuring safeguard compliance; and • The project road should be environmentally sustainable.

C. Environmental Management Plan Matrix

392. The EMP matrix provided in Table 60 (prepared as per contract package) follows the environmental impacts and proposed mitigation measures for the identified valued environmental components (VECs) identified and discussed in Chapter VI. The matrix provides an implementable plan with recommended mitigation measures for each anticipated impact and also assigns responsibilities for implementation, supervision and monitoring.

D. Environmental Monitoring and Reporting Program

393. The environmental monitoring program has the underlying objective to ensure that the intended environmental mitigations are realized and these results in desired benefits to the target population causing minimal deterioration to the environmental parameters. Such program targets proper implementation of the EMP. The broad objectives are: 133

• To evaluate the performance of mitigation measures proposed in the EMP. • To evaluate the adequacy of environmental assessment. • To suggest ongoing improvements in management plan based on the monitoring and to devise fresh monitoring on the basis of the improved EMP. • To enhance environmental quality through proper implementation of suggested mitigation measures. • To meet the requirements of the existing environmental regulatory framework and community obligations.

394. The EMOP matrix covering various performance indicators, frequency and institutional arrangements of the project in the construction and operation stages, along with the estimated cost, is summarized in Table 61. Key features of the EMOP is described in the following paragraphs.

1. Performance Indicators

395. The potential physical, biological and social components affecting the environment at critical locations serve as wider/overall Performance Indicators. However, the following specific environmental parameters can be quantitatively measured and compared over a period of time and are, therefore, selected as specific Performance Indicators (PIs) for monitoring because of their regulatory importance and the availability of standardized procedures and relevant expertise.

• Air Quality with respect to PM2.5, PM10, CO, NOx and SO2 at selected location. • Water Quality with reference to pH, DO, BOD, Oil and grease, COD, Suspended Solids, total dissolved solids, total solids, chlorides Turbidity and Alkalinity at crossing points on rivers/streams at selected points. • Noise and vibration levels at sensitive receptors (schools, hospitals, community/religious places and weak structures). • Survival rates of trees planted as compensatory plantation to compensate for lost forestland and compensatory plantation raised for removal of roadside trees.

396. Ambient Air Quality (AAQ) Monitoring: Ambient air quality parameters recommended for monitoring road development project are PM2.5, PM10, Carbon Monoxide (CO), Oxides of Nitrogen (NOx) and Sulphur Dioxide (SO2). These are to be monitored, right from the commencement of construction activity at selected locations of plants and machinery, crushers on sites, excavation works etc. Data should be generated quarterly excluding monsoon at the monitoring locations in accordance with the revised National Ambient Air Quality Standards formulated by MOEFCC in 2009 as well as IFC EHS air quality standards (Appendix-4).

397. Water Quality Monitoring: The physical and chemical parameters recommended for analysis of water quality relevant to road development project are pH, DO, BOD, Oil and grease, COD, total Suspended Solids, total dissolved solids, total solids, chlorides Turbidity and Alkalinity. The location, duration and the pollution parameters to be monitored and the responsible institutional arrangements are given in the Environmental Monitoring Plan. The monitoring of the water quality is to be carried out at locations identified along the project road during construction and operation phase. The Indian Standard Specifications – IS 10500: 1991 and IS 2296: 1992 is given in Appendix – 15.

134

398. Noise and Vibration Level Monitoring:The measurements for monitoring noise and vibration levels would be carried out at sensitive receptors, construction sites and at weak structures locations along the project road. The Ambient Noise Standards prescribed in the Noise pollution (Regulation and Control), Rules 2000 issued by the MOEFCC, GoI as well as WBG noise standards will be followed. Sound pressure levels would be monitored on a 24-hour basis. Noise should be recorded at “A” weighted frequency using a “slow time response mode” of the measuring instrument. Differences between IFC EHS and MOEFCC daytime and nighttime periods should be accounted for in establishing baseline noise levels prior to start of works. The CPCB standards are given in Appendix – 16.

399. Success of Re-vegetation: The project involves widening and up-gradation including construction of cross drainage structures hence these will require felling of trees. Such lost vegetation will be required to be replaced by compensatory plantation. As per policy of the State Government 10 trees have to be planted for each tree removed. These compensatory plantations will have to be monitored for 70% survival rate -after three years by the implementing agency. Such monitoring will be conducted through random samples. Such sampling should cover at least 5% of the area planted up. 135

For successful implementation of EMP, it is essential to orient engineers of PIU, FIUs, CSC and Contractor who would be mobilized for this project. One day environmental orientation workshop will be organized by the PIU (with support from ADB TA consultant, if required) after most staff of the CSC and contractor has been mobilized.

F. Environmental Reporting System

416. The reporting system will operate linearly with the contractor who is at the ground level of the implementation system reporting to the CSC, who in turn shall report to the PIU and FIUs. All reporting by the contractor and CSC shall be on a monthly basis. The CSC will compile the monthly reports into quarterly reports and then semi-annual environmental monitoring reports and submit them to the PIU. The PIU shall be responsible for preparing targets for each of the identified EMP activities. The environmental specialist of the PMS will consolidate semi-annual monitoring reports submitted of CSCs into semi-annual environmental monitoring reports for submission to PIU for their review and endorsement for further submission to ADB.

417. The PIU will review and endorse the monthly and semi-annual environmental monitoring reports submitted by the PMS and CSC. The PIU through TNHW will forward the consolidated semi-annual environmental monitoring reports to ADB for disclosure on the ADB website during the project construction period. The PIU will compile and submit consolidated annual environmental monitoring reports to ADB during the project operation stage until the Project Completion Report (PCR) is finalized.

418. During the implementation period, a compliance report may include description of the items of EMP, which were not complied with by any of the responsible agencies. It would also report to the management about actions taken to enforce compliance. It may, however, be noted that certain items of the EMP might not be possibly complied with for a variety of reasons. The intention of the compliance report is not to suppress these issues but to bring out the circumstances and reasons for which compliance was not possible (such as jurisdictional issues). This would help in reinforcing the implementation of the EMP. Photographic records will also be established to provide useful environmental monitoring tools. A full record will be kept as part of normal contract monitoring. Reporting and Monitoring Systems for various stages of construction and related activities have been proposed to ensure timely and effective implementation of the EMP.

419. A summary of the key environment safeguards activities and reporting system to be followed under the project is provided in the table 62 below.

X. CONCLUSIONS AND RECOMMENDATIONS

421. The project proposed for the improvement is classified as environment Category B project as per ADB SPS requirements. As per GOI requirements state highway road do not fall in the purview of EIA Notification 2006 of MOEFCC, therefore as per GOI norms environmental clearance is not required for this project. For ADB the categorization has been done based on environmental screening and assessment of likely impacts. While the environmental assessment ascertains that it is unlikely to cause any major significant environmental impacts, some impacts were identified attributable to the proposed project, all of which are localized and temporary in nature and easy to mitigate.

422. Road widening will be confined within the available RoW with minimum additional land acquisition. There is no presence sensitive environmental issue like wildlife sanctuary, national park, bio reserve, along the project road alignment and most of water body crossed by the road are non-perennial in nature.

423. The road section does not passes through any protected area, wildlife sanctuary, national park. There are no ecologically sensitive areas along the project road neither there are any archaeological/protected monument located in the vicinity of project corridor. The land use pattern around the proposed alignment is predominantly agricultural except in patches of section where land use predominantly mix of built-up and agriculture land.

424. The potential adverse impacts of the road sections upgrading are:

• Impacts on surrounding area due to tree cutting (1466) for the proposed widening; • Impacts due to conversion of about 18.0182 hectare of land for road widening purpose; • Temporary impact on land and air environment due to locating construction camp; • Temporary impact on land, air and water environment due to establishing and operating construction plants (Hot Mix Plant and Diesel Generator [DG] sets); • Impacts on trees due to removal on section of road with realignment and proposed bypass; • Impact on air quality, water quality, drainage, road users due to construction activities of project road; • Impact on land and water environment due to improper disposal waste water and improper disposal of solid waste generated from camps and construction activities; • Impact on occupational health and safety due to all on-site and off-site construction works; and • Induced cumulative impact on noise and air quality levels due to increase in traffic.

425. Measures such as use of EFRC i.e. slope protection measures are proposed to minimize the impacts of slope instability, compensatory afforestation @ 1:10 ratio, engineering alternatives to limit impacts on forest areas etc. are proposed to minimize the potential impacts.

426. Besides, series of mitigation measures have been proposed that are described in the IEE Report and addressed comprehensively in the environmental management plan. These include use of spoil disposal areas to minimize destruction of land forms along the alignment, proper sizing of hydraulic structures to assure adequate capacity and prevent destruction of adjacent land, provision of sign boards and noise barriers at sensitive receptor’s locations, identification

172

of vulnerable community infrastructure that must be preserved or replaced under construction contracts, identification of sensitive receptors and consultation of affected persons prior to finalization of road design to incorporate noise abatement measures, limits on location and access of workers and other provisions regarding construction to assure minimum impact, and other basic provisions on air pollution control, noise control, waste management as found in the EMP. All the above observations and mitigation measures will be included in the tender documents for contract works and the final contract agreement.

427. Application of these measures in parallel with MoRTH environmentally friendly road construction practices will reduce significantly any potential environmental impact. Impacts remaining on the physical environment (air and water pollution) are temporary and often occur away from the presence of people.

428. A systematic approach for surveillance and monitoring is provided by means of a management framework, and monitoring and reporting protocol. In general, the project received good support from local people. The local people appreciated that besides providing an all- weather efficient connectivity to large rural populations and improving the traffic scenario in the region, it will bear out several other socio-economic positive benefits. Follow-up public consultation is intended to provide future input to the identification of environmental impact during the construction phase as well as a grievance redress mechanism for project affected persons. The EMP is a living document and the same will be revised if necessary during project implementation or if there is any change in the project design and with approval of ADB during the construction period. The environmental mitigation measures are itemized in the EMP and the PIU shall ensure that EMP and EMoP are included in Bill of Quantity (BOQ) and forms part of bid document and civil works contracts for each package.

429. Before the start of civil works for the any section of the project road, the project proponent (TNHD and CKICP-PIU-EPC Contractor- ADB) must obtain necessary clearances / permits from statutory authorities.

430. Environmental benefits of the proposed road improvement and long-term project objectives far outweigh the manageable and temporary negative impacts that will arise during project construction and any residual or induced impacts during project operation phase. Provided the EMP is properly implemented there will be no significant negative impacts arising from the project.

Appendix 4: Comparison of World Bank and GoI Ambient Air Quality Standards

A comparison between the ambient air quality requirements between the World Bank (WB) Environment, Health and Safety (EHS) guidelines and the National Ambient Air Quality standards (NAAQS) under the Air (Prevention and Control of Pollution) Act, 1981 of GOI as given in table below shows that the NAAQS has requirements on three more parameters (Pb, Co and NH3) in comparison to the WB EHS. The NAAQS has differentiated standards for two types of areas: i) industrial, residential, rural and other areas and ii) ecologically sensitive areas. The WB EHS has guidelines values which are the required standards but allows for gradual compliance to the guideline values through staged interim targets. Most WB EHS guideline requirements are more stringent than NAAQS except for the NOx one year average in ecologically sensitive areas where the NAAQS requirements are more stringent.

Appendix 7: Detailed Analysis of Air Modeling

A. Introduction

1. The major impact on the air quality during the operation stage will be due to plying of vehicles on the proposed corridor. The impact on air quality depends upon traffic volume, traffic fleet including fuel type and prevailing atmospheric conditions. An unstable atmospheric condition disperses pollutants more and results in to low pollutant concentrations while stable atmospheric conditions buildup the pollution level. To assess the likely impacts on the ambient air quality due to the proposed highway project, the prediction of the carbon monoxide (CO) and particulate matter (PM), Nitrogen Dioxide (NOx) and Sulphur Dioxide (SO2) concentrations have been carried out using line source dispersion modelling approach, based on Gaussian equation. CO is an indicator pollutant for vehicular pollution. So, prediction of CO concentration is representative of the impacts of air pollution due to traffic movement. The modeling for this project has been carried out using AERMOD-9, a steady-state plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of both surface and elevated sources, and both simple and complex terrain, developed by the “The American Meteorological Society/Environmental Protection Agency Regulatory Model Improvement Committee (AERMIC)”. 2. It has been setup and run by using emission factors prevalent for Indian vehicles (ARAI, 2007) and hourly traffic volumes as predicted for the project. The study is conducted to predict 1- houly increment in CO and 24-houly increment in PM2.5, PM10, NOx and SO2 concentrations for the years 2020, 2025, 2030 and 2035.

B. Model descriptions

3. The AERMOD atmospheric dispersion modeling system is an integrated system that includes three modules: (a) A steady-state dispersion model designed for short-range (up to 50 kilometers) dispersion of air pollutant emissions from stationary industrial sources. (b) A meteorological data preprocessor (AERMET) that accepts surface meteorological data, upper air soundings, and optionally, data from on-site instrument towers. It then calculates atmospheric parameters needed by the dispersion model, such as atmospheric turbulence characteristics, mixing heights, friction velocity, Monin-Obukov length and surface heat flux. (c) A terrain preprocessor (AERMAP) whose main purpose is to provide a physical relationship between terrain features and the behavior of air pollution plumes. It generates location and height data for each receptor location. It also provides information that allows the dispersion model to simulate the effects of air flowing over hills or splitting to flow around hills. AERMOD also includes PRIME (Plume Rise Model Enhancements) [4] which is an algorithm for modeling the effects of downwash created by the pollution plume flowing over nearby buildings.

C. Source information

1. Traffic data

4. The fleet wise traffic volumes for the present study have been taken from the detailed feasibility report of the project. The annual average daily traffic (AADT) data is available for the proposed road through traffic survey. AERMOD model needs hourly average traffic volume. The total traffic hour volume is further categorized in to two-wheeler, four wheeler, Light commercial vehicles (LCVs), Bus and high commercial vehicles (HCVs), based on the traffic survey at different road stretched along the highway (Figure 1).

2. Emission factors

6. Emission factor is one of the important input parameters in AERMOD model. In the present study, the emission factors specified by the Automotive Research Association of India (ARAI, 2007) have been used for calculation of weighted emission factors. These emission factors have been expressed in terms of type of vehicles and type of fuel used (for petrol and diesel driven passenger cars).

7. The emission factor used in the present study for different vehicles type are given in table 2.

Appendix 9: Guidelines for Camp Site Management

A. Purpose

1. Campsite of a contractor represents the single potentially most polluting location during implementation of any road project. Air pollution may be caused by emissions from Crushers, Hot-Mix, and Concrete Batching Plants. Water pollution may be caused by discharge of sediment, oil & grease, and organics laden run-off from these plants and their ancillary facilities as well as workshops, residential quarters for the labor. Land may be polluted due to indiscriminate disposal of domestic waste or (accidental) release of hazardous solids from storage areas.

2. While the installation and operation of Crushers and Hot-Mix Plants are regulated by the respective Pollution Control Boards, the other sources described above usually do not appear to be causes of significant concern. Items to be considered for labor camps are mentioned briefly in Clause 105.2 (as part of 105: Scope of Work) of the Ministry of Road Transport and Highways (MoRTH) publication: Specifications for Road and Bridge Works. Some specific requirements for labor accommodation and facilities are to be met by the Contractor in line with Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act, 1996. Currently, there is no one-point guidance regarding the environmental management aspects of the Contractor’s campsite. This guideline on Campsites is designed to fill this gap.

B. Scope

3. This guideline covers the Contractors’ camp sites – whether used by in-house crew or by any sub-contractors’ crew. It covers siting, operation, maintenance, repair and dismantling procedures for facilities for labor employed on project (and ancillary) activities as well as equipment and vehicles. It does not include siting, operation, maintenance, repair and dismantling of major plants – Hot-mix Plant, Concrete Batching Plant, Crusher or Wet Mix Macadam Plant.

1. Siting, Establishing, Operation and Closure of Construction Camp

a. Potential Environmental Impacts

4. Construction camps require large areas for siting facilities like major plants, storage areas for material, residential accommodation for construction labor and supervisors, and offices. Removal of topsoil and vegetation from the land to be utilized for camps is the first direct impact of any such establishment. In addition, local drainage may be impaired if proper drainage is not effected by grading. Other impacts may include damage to ecologically important flora and fauna, if campsites are located close to such areas. Water pollution because of discharge of sediment, fuel and chemicals is also a possibility. Pollution of land due to indiscriminate disposal of construction wastes including scarified pavement, concrete and even substantial quantities of domestic wastes from residential areas can also be potentially disastrous, especially if the site is reverted to its original use after the project (mostly agriculture).

b. Mitigation Measures

2. Siting of Construction Camps

5. The following guidelines will assist the Contractor to avoid any environmental issues while siting construction camps:

269

• Maintain a distance of at least 1 km from boundaries of designated Reserved Forests, Sanctuary or National Park area for locating any temporary or permanent camps. • Maintain 500m from river, stream and lake and from ponds • Maintain 200 m from the boundary of state and national highways • Locate facilities in areas not affected by flooding and clear of any natural or storm water courses. • Locate campsites in the (most prevalent) downwind direction of nearest village(s). The boundary of the campsite should be at least 500m from the nearest habitation so that the incoming labor does not stress the existing local civic facilities. • The ground should have gentle slope to allow free drainage of the site. • Recorded consultations should be held with residents of the nearest settlement and/or their representatives to understand and incorporate where possible, what they would like to see within their locality.

3. Establishment, Operation, and Closure of Camps

• The facilities within the camp site should be laid out so that the separation distances suggested in other guidelines are maintained. A notional lay-out of the facilities except the major plants is included in this guideline. • Topsoil from the area of the plant shall be stored separately for the duration of the operation of the camp and protected from being washed away, unless agreed otherwise in writing with the owner. If stored, it will be returned on to its original location at the time of closure of the site. • The Contractor shall prepare, make widely available (especially to staff responsible for water and material management), and implement a Storm water Management Plan (SWMP) for (all) the site(s) following approval of the same by the Engineer. . • The Contractor shall prepare an Emergency and Spill Response Plan as per the requirements of Appendix 1 to Clause 501 of Specifications for Road and Bridge Works to cover the spillage of bitumen and/or chemicals like retarders, curing compounds, etc. • The Contractor shall prepare a Waste Management Plan describing the types and quantities that are likely to be generated from within the camp site, with the period and duration during the construction schedule; methods to be adopted to minimize these; methods of removal, treatment and (on-site or off-site) disposal for each type; as well as location of final disposal site, if any. • The Contractor shall provide safe ingress and egress for vehicles from the site and public roads and shall not impact existing through traffic. • Water tankers with sprayers must be available at the camp site at all times to prevent dust generation. • In case of stockpiles of stored material rising higher than wind-breaking perimeter fencing provided, sprinklers shall be available on site to prevent dusting from the piles during windy days. • On completion of works, the Contractor shall restore the site to the condition it was in before the establishment of the campsite, unless agreed otherwise in writing with the owner(s) of the site(s). If such a written agreement has been made, the Contractor shall hand over the site to the owner(s) in accordance with such an agreement. • Construction waste disposal should be disposed only at landfill facilities which are selected, designed, constructed and operated to ensure environmentally safe disposal, and these facilities have to be approved by the regulators.

270

4. Equipment and Vehicle-related issues

a. Potential Environmental Impacts

6. The maintenance and repair of equipment and vehicles in Contractor’s camp are activities that can have significant adverse impacts if not carried out properly. The concern mainly arises from discharge of wash water contaminated with oil and grease, whether from washing of vehicles or degreasing of equipment and vehicle parts. Vehicle washing, especially dirt from tires, also gives rise to sediment-laden run-off. No such discharges should be directly allowed into surface water bodies since they can be harmful to aquatic species.

b. Mitigation Measures

i. Vehicles

• All vehicles used by the Contractor must have copies of currently valid Pollution Under Control Certificates displayed as per the requirement of the Motor Vehicles Department for the duration of the Contract. • All vehicles and equipment will be fitted with silencers and/or mufflers which will be serviced regularly to maintain them in good working condition and conforming to the standard of 75dB (A) at 1m from surface of enclosure.

ii. Workshop and Maintenance areas

• These areas must have impervious flooring to prevent seepage of any leaked oil & grease into the ground. The area should be covered with a roof to prevent the entry of rainwater. • The flooring shall be sloped to from both directions to one corner where an oil- and-grease trap with sufficient capacity should be installed. All discharges from the workshop area must pass through the trap to remove the floating oil and grease before entering the drainage system of the site. The trap should be designed to provide a hydraulic residence time of about 20 minutes for the peak hourly discharge anticipated from the area (as per following figure). • Alternatively, degreasing can also be carried out using mechanical spray type degreaser, with complete recycle using an enclosure with nozzles and two sieves, coarse above and fine below, may be used as shown in the adjacent photograph. This arrangement will require some initial investment and running cost for the pump, but the payback period, in terms of the use of diesel, under Indian conditions, has been reported to be less than 1 year.

271

Slope of the Workshop area floor

O&G To drainage system for the site

Figure 1: Workshop Area Pollution Control

• All the waste oil collected, from skimming of the oil trap as well as from the drip pans, or the mechanical degreaser shall be stored in accordance with the Environment Protection (Storage and Disposal of Hazardous Wastes) Rules, 1989. For this purpose, metallic drums should be used. These should be stored separately in sheds, preferably bunded. The advantage of this arrangement is that it allows for accurate accounting in case the waste material is sold to oil waste recyclers or other users like brick-kiln owners who can burn such inferior fuel.

272

• A separate vehicle washing ramp shall be constructed adjacent to the workshop for washing vehicles, including truck mounted concrete mixers, if any, after each day’s construction is over, or as required. This ramp should have an impervious bottom and it should be sloped so that it drains into a separate chamber to remove the sediment from the wash water before discharge. The chamber should allow for a hydraulic residence time of about 10 minutes for discharge associated with the washing of each truck. Following figure 2 shows an outline sketch for a sedimentation chamber.

Figure 2: Sedimentation Chamber for vehicle washing ramp discharge

273

5. Facilities for Labour

a. Potential Environmental Impacts

7. The sudden arrival and relatively longer duration of stay of construction crew can cause substantial strain on the existing infrastructure facilities like water supply, sanitation and medical care, especially in rural areas. Pollution from domestic wastes can affect local sources of water supply and may harm the crew themselves as well as local residents. Improper sanitation and inadequate health care also potential bottlenecks that the Contractor can eliminate with relatively little effort.

b. Mitigation Measures

8. It should be emphasized that the Indian Law requires that the Contractor provide several facilities to for the workers as per Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act, 1996. Some of the provisions described herein are more stringent to act as benchmark for improved environmental performance of road projects: • The contractor shall provide free-of-charge temporary accommodation to all the labour employed for the project. The accommodation includes separate cooking place, bathing, washing and lavatory facilities. At least, one toilet will be provided for every 35 people and one urinal will be provided for every 20 persons. More toilets and/or urinals may have to be provided if the Engineer decides that these numbers are insufficient. In case female labourers are employed, separate toilet and urinals will be provided in locations clearly marked “Ladies Toilets” in a language understood by most labourers. • The contractor shall ensure the supply of wholesome water for all the labour, including those employed by any other agency working for the contractor. These locations will be marked “Drinking Water” in the language most commonly understood among the labour. In hot season, the contractor shall make efforts to ensure supply of cool water. No water point shall be located within 15 m of any washing place, urinal, or latrine. • The contractor shall ensure that adequate cooking fuel, preferably kerosene or LPG, is available on-site. The contractor will ensure that wood/ coal are not used as fuel on the site. Workers need to be made aware of this restriction. In cases where more than 250 labours are employed, canteen facility should be provided by the Contractor. • A crèche must be provided in each campsite where more than 50 female labourers are employed, whether directly or indirectly, for the project or its ancillary activities. • Contractor must provide adequate facilities for first-aid treatment at the campsite. A doctor / ambulance should be available on call for the duration of project implementation. • The contractor shall obtain the approval of the Engineer for these facilities within 30 days of mobilization.

Appendix 10: Guidelines for Waste (Debris and Spoil) Disposal and Management

A Waste disposal and management plan will be prepared by the contractor before start of construction works and submitted to CKICP, PIU-ADB and the Construction Supervision Consultant for their review and approval. The management plan will follow the guidelines as given below: (i) The debris disposal site should be identified which are preferably barren or low- lying areas away from settlements. (ii) Contractor to prepare spoil disposal plan which identifies spoil disposal sites including volume of spoils that can be accommodated by each site, and agreed restoration measures (e.g. revegetation, compaction, provision of drainage, etc.) and timeline (iii) Prior concurrence will be taken from concerned Government Authorities or land owner for selected disposal sites and restoration measures (iv) Due care should be taken during site clearance and disposal of debris so that public/ private properties are not damaged or affected, no traffic are interrupted. (v) All efforts should be made to use debris in road construction or any other public utilities to minimize spoils and debris (vi) If immediate disposal is not possible, the debris and spoils should be stored at site ensuring that existing water bodies and drains within or adjacent to the site are kept safe and free and no blocking of drains occurs until ready to be transported to final spoils disposal site (vii) All dust prone material should be transported in a covered truck. (viii) All liquid waste like oils and paint waste should be stored at identified locations and preferably on a cemented floor. Provision of spill collection pit will be made in the floor to collect the spilled oil or paint. These should be sold off to authorized recyclers. (ix) All domestic waste generated at construction camp preferably be composted in portable mechanized composter. The composted material will be used as manure. In case composting is not feasible, the material will either be disposed off though municipal waste disposal system or disposed of through land burial. The dump site must be covered up with at least six inch thick layer of soil. (x) Only appropriately design and compliant landfills will be used for disposing waste (xi) All efforts should be made that no chemical/ oily waste spill over to ground or water bodies. (xii) All precautions should be followed for emergency preparedness and occupational health & safety during construction and handling wastes and spoils. (xiii) Provision of fire extinguishers will be made at the storage area (xiv) Adequate traffic control signals and barriers should be used in case traffic is to be diverted during debris disposal. All efforts should be made to ensure avoidance of traffic jam, which otherwise results in air pollution, noise pollution and inconveniences to the road users and adjacent communities. (xv) Hazardous waste and chemicals should be stored in a dedicated storage area that has: 1) weather protection, 2) solid impermeable surface and drainage to treatment system, 3) security fence/lock, 4) primary and secondary containment with 110% volume for liquids. (xvi) Domestic waste shall only be disposed of at the approved, appropriately designed, compliant waste management facility (landfill). Land burial of waste shall not be permitted.

Records: The following records will be maintained • Generation and disposal quantity with location of disposal • Recyclables waste generation and disposal

277

• Domestic waste disposal locations details

Reporting: The waste generation and disposal details will form part of quarterly report to CKICP, PIU- ADB

Responsibility: Prime Responsibility: Contractor will be responsible for waste management and reporting Supervisory Responsibility: Construction Supervision Consultant (CSC) will check the contractor’s adherence to the above guidelines

278

Appendix 11: Guidelines for Borrow Area Management

A. Purpose

1. Borrow areas are generally required to provide material for road construction sites, can have significant adverse environmental effects, especially on ecologically sensitive areas. Borrow areas can become environmental hotspots and can significantly affect the visual appearance of an area. Special mitigation and management measures are often required to avoid or minimise the environmental and social impacts of borrow areas.

B. Scope

2. These guidelines for borrow areas cover: • statutory approvals • environmental and social impacts of borrow areas • selection of borrow areas • operation of borrow areas • rehabilitation of borrow areas

3. The guidelines seek to ensure that Contractors: • comply with the regulatory requirements in force at the time • reasonably manage any impacts • reinstate and rehabilitate the land appropriately • consult with affected communities

C. Impacts

4. Some of the potential impacts of borrow areas are: • trucks transporting materials to the site causing air pollution, and noise and vibrations • ponds of stagnant water forming in excavated areas giving rise to the breeding of mosquitoes and the spreading of malaria and other mosquito-borne diseases • natural beauty of the landscape being affected by excavations and the removal of vegetation • natural drainage systems in the area being affected by excavations • agriculture land and productive soils being lost, especially in paddy field areas

5. Borrow areas are not generally specified in Contract documents but rather it is generally the responsibility of Contractors to identify borrow areas and obtain the necessary consent from land owner and approval from SC.

6. In IRC: 10 and Clause 305.2.2.2 of MoRTH Specification, exclusive guideline has been given for borrow areas located alongside the road and only some of the requirements have been indicated for borrow areas located outside the road land. Following guideline is proposed to supplement the existing stipulation in IRC:10 and Clause 305.2.2.2 of MoRTH Specification for Roads and Bridge Works:

D. Location • Identify areas having present land use as barren land, riverside land. Otherwise, un-irrigated agriculture land or land without vegetation and tree cover; • Prefer borrow areas on bed of irrigation water storage tank; • Prefer areas of highland with respect to surroundings; • Avoid locating borrow area close to any road (maintain atleast 30 m distance from ROW and 10 m from toe of embankment, whichever is higher);

279

• Should be at least 1.5 km away from inhabited areas; • Maintain a distance of about 1.5km from ecologically sensitive area i.e. Reserve Forest, Protected Forest, Sanctuary, wetland etc.; • Maintain a distance of about 1.5 km from school, hospital and any archaeological sites; • Having adequate approach road with minimum length of earthen road; • Ensure that unsuitable soft rock is not prominent within the proposed depth of excavation which will render rehabilitation difficult; • Depth of excavation should be decided based on natural ground level of the land and the surroundings, and rehabilitation plan. In case higher depth of excavation is agreed with backfilling by unsuitable excavated soil (from roadway), then filling should be adequately compacted except topsoil which is to be spread on topmost layer (for at least 20cm thick).

E. Operation

• Controlled operation as per agreed / approved plan; • Preservation of topsoil at designated areas e.g. corners of the area etc.; • Maintain necessary buffer zone in all directions and go for vertical cut within this area. Final cut slope should be maintained within the buffer zone; • Step-wise excavation if borrow area is located on inclined area having more than 2% slope; • Restricting excavation up to 2m for each stages of operation if allowed depth is more; • Avoid cutting of any tree of girth size > 30cm2. if any tree cutting is inevitable, prior permission (written) from the competent authority should be taken and compensatory plantation has to be raised.

F. Rehabilitation

• Prior approval of Rehabilitation Plan considering terrain, land use and local need; • Restricting operation as agreed by landowner and approved by the Engineer; • Rehabilitation within agreed timeframe and before taking over; • Integrate debris disposal and borrow area redevelopment.

G. Management Procedure

7. The important aspects of this procedure are: • The first and foremost thing is to have tentative estimate of borrow material requirement chainage-wise. For this, Bill of Quantities(BOQ) quantity for earth work, which is given as total quantity for the entire package/milestone, has to be distributed chainage-wise. The requirement of borrow material chainage- wise then has to be estimated based on the suitability of roadway excavation material for reuse and BOQ. • Contractor to site borrow areas fulfilling environmental requirements and obtaining one time approval of the Engineer both on quality as well as environmental consideration thereby integrating environmental safeguard measures into day-to-day activities; • Contractor to submit environmental information in prescribed format for obtaining Engineer’s approval, as given in the following format (Borrow Area Identification). The format has been so designed that it stipulates the requirements as well as what is actual for each borrow areas and could be

2 Plant having girth size more than 30cm is considered as tree.

280

easily understood by any person, whoever in-charge of identifying borrow areas; • Contractor to submit Borrow Area Layout Plan as attachment to the format showing the land use of the proposed and surrounding area along with the presence of other environmental features such as water bodies, forests, settlement, temple and any sensitive receptor i.e. health and educational institution, roads etc. within a radius of 1.5km area from the boundary of the borrow area; • Contractor to prepare and submit Block Contour Map of each borrow area (especially which are located close to road and on undulating terrain) for deciding on operation and redevelopment plan; • Contractor to prepare Operation Plan and submit as attachment to the format including cross sections on both directions (x,y) mentioning natural ground level, depth of topsoil (if any), total depth of excavation, cut side slope and bed slope; • Contractor to prepare Rehabilitation/ Restoration Plan and submit as attachment to the format include cross sections on both directions (x,y) mentioning natural ground level, excavated profile, finished profile after rehabilitation, volume of spoils that can be accommodated etc.; • Contractor to maintain Borrow Material Register; • Periodic joint inspections of each borrow area until rehabilitation is complete as agreed and approved. • The checklist for periodic inspection is given in this appendix.

Appendix 12: Guidelines for Quarry Area Management

A. Purpose

1. Quarries generally required to provide material for road construction sites, can have significant adverse environmental effects, especially on ecologically sensitive areas. Quarries can become environmental hotspots and can significantly affect the visual appearance of an area. Special mitigation and management measures are often required to avoid or minimise the environmental and social impacts of quarries.

B. Scope

2. These guidelines for quarries cover: • statutory approvals • environmental and social impacts of quarries • selection of quarries • operation of quarries • rehabilitation of quarries

3. The guidelines seek to ensure that Contractors3: • comply with the regulatory requirements in force at the time • reasonably manage any impacts • reinstate and rehabilitate the land appropriately • consult with affected communities C. Impacts

4. Some of the potential impacts of quarries are: • rock blasting causing air pollution, and noise and vibrations • trucks transporting materials to the site causing air pollution, and noise and vibrations • ponds of stagnant water forming in excavated areas giving rise to the breeding of mosquitoes and the spreading of malaria and other mosquito- borne diseases • natural beauty of the landscape being affected by excavations and the removal of vegetation • natural drainage systems in the area being affected by excavations

5. The procedure for identification and finalization of quarry site/s shall be as given below: • Estimating the quantity of quarry material to be collected from each quarry area • Only licensed quarry will be used • New quarry will be at least 1.5 km away from the settlement, forest and other ecologically sensitive areas • Away from water body • Contractor shall identify alternative quarry sites along the whole corridor based on required quantity and environmental consideration as given in the following prescribed format of Quarry source identification. • Contractor shall submit to the Engineer the detailed information / documents as prescribed in the format;

Use of Explosive for Blasting

1. General

7. Blasting shall be carried out in a manner that completes the excavation to the lines indicated in drawings, with the least disturbance to adjacent material. It shall be done only with the written permission of the Engineer. All the statutory laws, regulations, rules, etc., pertaining to the acquisition, transport, storage, handling and use of explosives shall be strictly followed.

8. The Contractor may adopt any method or methods of blasting consistent with the safety and job requirements. Prior to starting any phase of the operation the Contractor shall provide information describing pertinent blasting procedures, dimension and notes.

9. The magazine for the storage of explosives shall be built as per national / international standards and located at the approved site. No unauthorized person shall be admitted into the magazine which when not in use shall be kept securely locked. No

286

matches or inflammable material shall be allowed in the magazine. The magazine shall have an effective lightning conductor. The following shall be displayed in the lobby of the magazine: • A copy of the relevant rules regarding safe storage in English, Portuguese and in the language with which the workers concerned are familiar. • A statement of up-to-date stock in the magazine. • A certificate showing the last date of testing of the lightning conductor. • A notice that smoking is strictly prohibited.

10. All explosives shall be stored in a secure manner in compliance with all laws and ordinances, and all such storage places shall be clearly marked. Where no local laws or ordinances apply, storage shall be provided to the satisfaction of the Engineer and in general not closer than 300 m from the road or from any building or camping area or place of human occupancy. In addition to these, the Contractor shall also observe the following instructions and any further additional instructions which may be given by the Engineer and shall be responsible for damage to property and any accident which may occur to workmen or the public on account of any operations connected with the storage, handling or use of explosives and blasting. The Engineer shall frequently check the Contractor’s compliance with these precautions.

2. Materials, Tools and Equipment

11. All the materials, tools and equipment used for blasting operations shall be of approved type. The Engineer may specify the type of explosives to be allowed in special cases. The fuse to be used in wet locations shall be sufficiently water-resistant as to be unaffected when immersed in water for 30 minutes. The rate of burning of the fuse shall be uniform and definitely known to permit such a length being cut as will permit sufficient time to the firer to reach safety before explosion takes place. Detonators shall be capable of giving effective blasting of the explosives. The blasting powder, explosives, detonators, fuses, etc., shall be fresh and not damaged due to dampness, moisture or any other cause. They shall be inspected before use and damaged articles shall be discarded totally and removed from the site immediately.

3. Personnel

12. The blasting operation shall remain in the charge of competent and experienced supervisor and workmen who are thoroughly acquainted with the details of handling explosives and blasting operations.

4. Blasting Operations

13. The blasting shall be carried out during fixed hours of the day preferably during the mid-day luncheon hour or at the close of the work as ordered in writing by the Engineer. The hours shall be made known to the people in the vicinity. All the charges shall be prepared by the man in charge only.

14. The Contractor shall notify each public utility company having structures in proximity to the site of the work of his intention to use explosives. Such notice shall be given sufficiently in advance to enable the companies to take such steps as they may deem necessary to protect their property from injury. In advance of any blasting work within 50 m of any railway track or structures, the Contractor shall notify the concerned Railway Authority of the location, date, time and approximate duration of such blasting operations.

15. Red danger flags shall be displayed prominently in all directions during the blasting operations. The flags shall be planted 200m and 500m from the blasting site in all directions

287 for blasting at work site and quarry, respectively. People, except those who actually light the fuse, shall be prohibited from entering this area, and all persons including workmen shall be excluded from the flagged area at least 10 minutes before the firing, a warning siren being sounded for the purpose.

16. The charge holes shall be drilled to required depths and at suitable places. Blasting should be as light as possible consistent with thorough breakage of the material necessary for economic loading and hauling. Any method of blasting which leads to overshooting shall be discontinued.

17. When blasting is done with powder, the fuse cut to the required length shall be inserted into the hole and the powder dropped in. The powder shall be gently tamped with copper rods with rounded ends. The explosive powder shall then be covered with tamping material which shall be tamped lightly but firmly.

18. When blasting is done with dynamite and other high explosives, dynamite cartridges shall be prepared by inserting the square cut end of a fuse into the detonator and finishing it with nippers at the open end, the detonator gently pushed into the primer leaving 1/3rd of the copper tube exposed outside. The paper of the cartridge shall then be closed up and securely bound with wire or twine. The primer shall be housed into the explosive. Boreholes shall be such size that the cartridge can easily go down. The holes shall be cleared of all debris and explosive inserted. The space of about 200 mm above the charge shall then be gently filled with dry clay, pressed home and the rest of the tamping formed of any convenient material gently packed with a wooden rammer.

19. At a time, not more than 10 such charges will be prepared and fired. The man in charge shall blow a siren in a recognised manner for cautioning the people. All the people shall then be required to move to safe distances. The charges shall be lighted by the man- in-charge only. The man-in-charge shall count the number of explosions. He shall satisfy himself that all the charges have been exploded before allowing the workmen to go back to the blasting site.

5. Misfire

20. In case of misfire, the following procedure shall be observed:

• Sufficient time shall be allowed to account for the delayed blast. The man- in-charge shall inspect all the charges and determine the missed charge. • If it is the blasting powder charge, it shall be completely flooded with water. A new hole shall be drilled at about 450 mm from the old hole and fired. This should blast the old charge. Should it not blast the old charge, the procedure shall be repeated till the old charge is blasted. • In case of charges of gelignite, dynamite, etc., the man-in-charge shall gently remove the tamping and the primer with the detonator. A fresh detonator and primer shall then be used to blast the charge. Alternatively, the hole may be cleared of 300 mm of tamping and the direction then ascertained by placing a stick in the hole. Another hole may then be drilled 150 mm away and parallel to it. This hole shall then be charged and fired when the misfired hole should explode at the same time. The man-in-charge shall at once report to the Contractor’s office and the Engineer all cases of misfire, the cause of the same and what steps were taken in connection therewith. • If a misfire has been found to be due to defective detonator or dynamite, the whole quantity in the box from which defective article was taken must be sent

288

to the authority directed by the Engineer for inspection to ascertain whether all the remaining materials in the box are also defective.

6. Account

21. A careful and day to day account of the explosive shall be maintained by the Contractor in an approved register and manner which shall be open to inspection by the Engineer at all times.

22. During quarry operation, periodic joint inspection should be carried out by the Contractor and Engineer’s representatives.

23. A typical checklist for the same is given here.

Appendix 13: Noise Modeling Details 1. Federal Highway Administration's Traffic Noise Model (FHWA TNM) helps for highway traffic noise prediction and analysis. TNM computes highway traffic noise at nearby receivers. As sources of noise, it includes noise emission levels for the following vehicle types: • Automobiles: all vehicles with two axles and four tires -- primarily designed to carry nine or fewer people (passenger cars, vans) or cargo (vans, light trucks) -- generally with gross vehicle weight less than 4,500 kg (9,900 lb); • Medium trucks: all cargo vehicles with two axles and six tires -- generally with gross vehicle weight between 4,500 kg (9,900 lb) and 12,000 kg (26,400 lb); • Heavy trucks: all cargo vehicles with three or more axles -- generally with gross vehicle weight more than 12,000 kg (26,400 lb); • Buses: all vehicles designed to carry more than nine passengers; and • Motorcycles: all vehicles with two or three tires and an open-air driver / passenger compartment.

2. The procedure for prediction of noise levels involves the following steps: 1. Identification of various receivers 2. Determination of landuse and activities which may be affected by the noise generated 3. Assemble input parameters 4. Application of the model

3. The description of the components to predict noise level are as follows: a. Receivers: TNM calculates the sound levels at the input receivers. In this study two type of receivers selected to assess the impacts of moving traffic on surrounding noise level. One, discrete receptor and second, grid receptor. b. Land uses: Land use along the road is obtained from the topographic drawings. This information provides the range of shielding and absorption factors to be applied at the various receivers. c. Input Parameters: Traffic volume for the projected period is obtained from the traffic projections. The total number of vehicles passing per hour by type - light, medium and heavy along with their average speed is used for predictions. d. Average Noise Level: All vehicles produce noise, which is taken as the base, and the cumulative noise at the receiver distance due to the whole traffic is estimated. The average noise level varies depending on the type of vehicle. e. Application of Model: Equivalent noise levels due to traffic at the receivers are estimated using Federal Highway Noise model. Equivalent Sound Level (TEQ, denoted by the symbol, LAeqT): Ten times the base-10 logarithm of the square of the ratio of time-average, mean-square, instantaneous A-weighted sound pressure, during a stated time interval, T (where T=t2-t1), and the reference mean-square sound pressure of 20 : Pa, the threshold of human hearing, e.g., 1HEQ, denoted by the symbol, LAeq1H, represents the hourly equivalent sound level. LAeqT is related to LAE by the following equation :

LAeqT = LAE - 10*log10(t2-t1)

where LAE = Sound exposure level in dB

Sound Exposure Level (SEL, denoted by the symbol, LAE): Over a stated time interval, T (where T=t2-t1), ten times the base-10 logarithm of the ratio of a given time integral of squared instantaneous A-weighted sound

292

pressure, and the product of the reference sound pressure of 20:Pa, the threshold of human hearing, and the reference duration of 1 sec. The time interval, T, must be long enough to include a majority of the sound source’s acoustic energy. As a minimum, this interval should encompass the 10 dB down points. Annual average daily motorized traffic data is given in table 1.

Observations

4. Predicted noise levels (Leq) near the receivers are found to be marginally higher than desired levels for the respective landuse categories for receptors falling within 50m from road edge. The baseline noise levels(2019) are already higher than the permissible limits of CPCB for different landuse categories for day and night. The predicted levels show

293 increase in noise levels for future years at all receivers considering increase in traffic volume. The incremental noise levels for future years exceeds the allowable limit of 3 dB (A) from the baseline levels. Mitigation measures suggested in EMP should be adopted for the sensitive receptors falling within 50 m from road edge of the road corridor.

Noise dispersion

5. A small road corridor has been selected to develop noise contour for base year as well as future years also. The contour lines are generated by plotting a contour zone within 30 m distance from edge of the road on both side of the road. Due to model limitation, it is not possible to select the whole road corridor in the modelling domain. Therefore, spatial dispersion of noise has been shown with a small stretch of road. Figure 2 to 5 shows noise level contour around a small road corridor for year 2020, 2025, 2030 and 2035 respectively. These predicted results are for peak traffic hours. During non-peak traffic hours, the noise levels are very less compared to noise level for peak traffic hours.
