CHAPTER - I INTRODUCTION

1.1 Overview

The North Karnataka Urban Sector Investment Program (NKUSIP) proposes to improve the environmental quality of the urban areas through better urban infrastructure facilities and thus improve living conditions of the urban people. In the wake of poor infrastructure facilities and services such as water supply, sewerage and sanitation, the risk of infectious diseases through exposure to unhealthy environment runs high, particularly in the case of urban poor. Hence, the proposed Investment Program aims at minimizing or mitigating the risk and ensures the well- being of people.

Though the Investment Program aims to improve the environmental condition of urban areas, the proposed improvements of infrastructure facilities may exert certain adverse impacts on the natural environment. While developing urban infrastructure facilities, impacts during the construction stage are expected to be more severe than the operation phase, though for a short duration. Exceptions being some facilities such as sewage treatment plant, which may also exert adverse impacts during the operation phase also, if due care is not taken. Again, most of the impacts are activity- specific. However, if due care is taken during the construction phase, investment Program negative impacts will be far outweighed by positive impacts.

1.2 Environmental Regulatory Compliance

The components of NKUSIP include environmental sanitation infrastructure, water supply infrastructure, urban roads improvement, slum infrastructure, and non-municipal infrastructure projects. Sub-components, which fall under the ambit of environmental regulations and mandatory requirement, are indicated in the Table -1.

Table – 1 Environmental Regulatory Compliance of NKUSIP Components

Sub- Component Applicability of Compliance Criteria Acts/Guidelines Sewage Environmental (Protection) Act, • Consent for Establishment and Treatment Plant 1986 Consent for Operation from Water (Prevention and Control of KSPCB as per Water Act. Pollution) Act, 1974 All sub- The Environment Policy and • Categorization of sub-project components Operations Manual (OM) 20: components into A, B or C and Environmental Considerations in developing required level of ADB Operation environmental assessment for each c ompone nt

The above table indicates that as far as GoI and GoK Acts/Guidelines are concerned, the proposed Investment Programs may not need to go through environmental assessment process; however, as specified, few sub-pro90ject components may require consent from Competent Authorities. The ADB guidelines, on the other hand, stipulate addressing environmental concerns, if any, of a proposed activity in the initial stages of Investment Program preparation. For this, the ADB Guidelines categorizes the proposed components into varies categories (A, B or C) to determine the level of environmental assessment required to address the potential impacts. Level of Environmental A ssessment required for each category of Investment Program, as per ADB’s Environmental Assessment Guidelines 2003 is presented below.

(i) Category A. Sub-project components with potential for significant adverse environmental impacts. An environmental impact assessment (EIA) is required to address significant impacts.

(ii) Category B. Sub-project components judged to have some adverse environmental impacts, but of lesser degree and/or significance than those for Category A projects. An initial environmental examination (IEE) is required to determine whether significant environmental impacts warranting an EIA are likely. If an EIA is not needed, the IEE is regarded as the final environmental assessment report.

(iii) Category C. Sub-components unlikely to have adverse environmental impacts. No EIA or IEE is required, although environmental implications are still reviewed.

1.3 Purpose of Initial Environmental Examination

The NKUSIP Package IV – Bellary covers Seven sub- project towns. To fulfil the ADB’s Environmental Assessment requirement for sector loans, the Initial Environmental Examination of sub-project were carried out. Owing to the scale and nature of the proposed infrastructure components and environmental profile of the NKUSIP sub – project towns, prima facie almost all Investment Program components are unlikely to have adverse environmental impacts.

Therefore, as per the ADB’s Environmental Assessment Guidelines, the sub-project components proposed in Raichur under NKUSIP are categorized as ‘B’ and it is proposed to carryout Initial Environmental Examination (IEE) for the proposed activities/Project.

1.4 Scope of IEE The IEE was based mainly on secondary sources of information and field reconnaissance surveys; no field monitoring (Environmental) survey was conducted. Stakeholder consultation was an integral part of the IEE.

DESCRIPTION OF THE INVESTMENT PROGRAM COMPONENTS

2.1 NKUSIP Goal

The North Karnataka Urban Sector Investment Program (NKUSIP) will finance investment for (i) Environmental Sanitation Infrastructure; (ii) Water supply Infrastructure; (iii) Urban Roads Improvement; (iv) Poverty Alleviation; (v) Non- Municipal Infrastructure; (vi) Institutional Development; and (vii) Investment Program Assistance. The overall development goal of the NKUSIP is to facilitate economic growth in the towns of North Karnataka and bring about urban development through equitable distribution of urban basic services to the citizens that are environmentally sound and operationally sustainable. The development purpose is designed to assist Urban Local Bodies (ULBs) to “promote good urban management, and develop and expand urban infrastructure to increase economic opportunities and to reduce vulnerability to environmental degradation and urban poverty”.

The following are the urban infrastructure components proposed under the NKUSIP.

1. Water Supply; 2. Sewerage; 3. Urban Drainage; 4. Urban Roads; and, 5. Poverty alleviation and 6. Slum improvement

2.2 Need Infrastructure Improvement

Raichur is an important destination for industrial and commercial growth due to availability of water. Providing basic amenities to ensure high level of performance in Environmental safe guard is quite necessary to ensure long term urban sustainability. A study conducted by Department of Forest , Ecology & Environment, Government of Karnataka, 2003 has shown that the cities in the state of Karnataka has poor Environmental performance due to lagging in ensuring basic infrastructure facilities to the urban population.

2.2.1 Karnataka - Health Status

In addition to the associated Environmental pollution, importantly, due to lack of safe and adequate water supply and sanitation facilities, the risk of infectious diseases through exposure to unhealthy environment runs high, particularly in the case of urban poor The State of Environment Report (SOER), 2003, Karnataka, brings out the fact that the lack of safe water supply and sanitation facilities is essentially leading to the health related consequences.

The yearly occurrence of water borne diseases like Cholera and Gastroenteritis makes it very clear that Environmental Impacts of water on health is very profound and significant.”

Existing Infrastructure Facilities in Raichur town

2.2.2 Sewerage System

First sewerage system in Raichur was commissioned during the year 1971 with sewer lines of 55 km length. Subsequently another 30 km sewer were laid during 1991. The total network of sewers length of 85 km thus covers only about 40% of the town area. In the remaining area, only septic tanks and dry latrines exist to dispose the human waste / waste water. Also in certain areas, sludge and night soil is directly disposed into the roadside/storm water drains causing unhygienic conditions. Even in the areas covered by UGD are also most of the wastewater joins the open drains as the sewerage system is damaged.

- Total area of Raichur town – 50.70 Sq.kms - Total coverage Raichur area about 40 %. - Coverage of Individual House Hold Connection 19.77%w - Total length of roads of various categories – 476 km. - Tentative length of sewers laid –85 km.

Table - 4 indicates the access to the sewerage and sanitation facilities for various households in Raichur. Only 6 percent of the surveyed non-slum households are connected to the UDG system, while none of the slum households are connected. Majority (49 percent) of the non- slum households depend on septic tanks and 16 percent use low- cost sanitation (LCS). Around 45 percent of the slum households and 21 percent of the non-slum households do not have any facilities and resort to open defecation.

At present there are two sewage treatment plants based on waste stabilization ponds with total capacity of 20.50 MLD, located near Hosur village and Ekalaspur village. Sewage does not reach Hosur STP, as the outfall sewer is damaged and Ekalaspur STP receives only 10 percent of the sewage flow of the three zones. The farmers tap the sewage from the outfall sewer for irrigation use. Thus, both the STPs are not working up to their efficiency. The wastewater from the ponds is pumped into the fields and is being used for agricultural purpose with out any treatment.

The anticipated demand for sewerage facility in Raichur in 2026 will increase to 36 MLD. The existing sewer network falls short even the present demand. Thus an Up gradation of the system is proposed under this investment Program

2.2.3 Water Supply Rehabilitation

Presently Raichur has three water supply schemes which were subsequently implemented during the year of 1936 and 1976 on a bank of Krishna River and Tungabhadra canal (Rampur water source) with capacity of 2.27 MLD and 18.16 MLD respectively with a distance 4 km from town near Rampur village. . In addition to this in 2003, augmentation of water supply with Krishna River as source was implemented designed to supply 40 MLD water (New Krishna WSS). Out of this, 10 MLD is provided for supply to the Industrial Growth Centre. The WTP is located in the Industrial Growth Centre. The source works are located upstream of raw water intake of Raichur Thermal Power Station. Thus the present available supply of water is 42.27 MLD against the requirement at consumer end of 25.21 MLD at 100 lpcd.

2.2.4. Drainage Up gradation

The drainage system in Raichur town mainly consists of five primary drains, which run through the town in East-West or South North direction and tertiary drains which are built around these primary drains.

Table : 5 Drainage system in Raichur . Drains. Length in Km Distribution Open drains (Pucca) 44.00 Kms. 67.50%

Open drains (Kutcha) 3.20 Kms. 4.90%

Closed drains (Pucca) 7.50 Kms. 11.50% Primary drain channels 10.50 Kms. 16.10% Total 65.20 Kms.

Source : DPR ( Detail Project Report ) Raichur.

The existing Drainage System carries Storm in rainy season and waste water in other season. The field inspection reveals that the most of the drains are choked up due to dumping of garbage and debris in secondary and tertiary drains. Practically the above drains are used by households as a dumping yard. In addition due to long neglect of O&M operation of the system most of the drains are in choked condition. Considering and taking in account above problems it is prime importance to up grade existing drainage system.

Proposed Improvement in Basic Infrastructures Of Raichur Town

2.3 Sub-project Component Description 2.3.1 Sewerage System

Around 85 km of the existing sewers lines is in bad condition and cannot be rehabilitated due to non-conformity with the proposed sewer network, being at greater depths. So new sewer network of 299.3km will be provided to replace the existing and expand the system into uncovered areas and also to cater for the future growth. This additional network will serve populations upto the year 2026

It is proposed to construct two new STP’s as per t he zones at existing sites of ST P’s o n e at Ekalaspur and Hosur Villages of total capacity 36.00MLD. Hence the total capacities of the proposed facultative aerated lagoons based STPs at Ekalaspur and Hosur will be 24.00 MLD and 12.00 MLD respectively.

STPs based on facultative aerated lagoons are designed to treat the sewage to the standards for stream disposal even though the treated sewage is expected to be utilized for agricultural purposes. Above 75% reduction in the BOD and COD values shall be expected in the facultative ponds attributing to the design requirement. T able-6 shows the design parameters of STPs.

The secondary treatments units are the aerated lagoons/ with a liquid depth of 5.0mts and1.5mts for second and third stages. Impervious lining to the bed of the pond and sidewalls with retaining is proposed.

The tertiary treatment is proposed with chlorine disinfection and mixing baffles to mix the chlorine solution. The disinfected treated sewage flows to outlet channel and proposed to be used for irrigation purpose. The Buffer Zone is also proposed for green plantations around the site. There are provisions for access roads, lighting, and etc. with the total area completely fenced and entry into the STP premises is restricted to the authorized ones

2.3.2 Water Supply

As per the population forecast for 2011, 2026 and 2041 and considering at 100 lpcd at consumer end the requirements are 27.13 Mld, 38.40 Mld and 52.63mld against the present scheme which meet total requirement up to 2026 including the system losses. Hence it is necessary to augment some components of the scheme to meet the proposed demands for the projected population for the year 2026 and 2041 and accordingly the project is formulated.Raichur is more or less situated mid way between Tunga Bhadra River 30 Kms on the south and Krishna River 22 Kms on the north. These sources are studied and investigated in order to meet demand of projected population with demand of water of 38.40 Mld and 52.30 Mld in 2041. The proposed water supply system rehabilitation in Raichur aims at providing safe, adequate and reliable water supply to the inhabitants. The objectives of system improvement are:

(i) Improving the longevity of the individual components and the system; (ii) Improving the operational performance of the components and the system; and (iii) Reducing the loss of the water and increasing the utilizable output of the system.

2.3.3 Urban Drainage

The proposal conceived in this report is to improve the existing storm water drains by transforming the discontinuous stretches into a continuous one so that the storm water is properly and adequately drained without overflows and does not lead to flooding in low lying areas. The proposal for Rs 345.00 lakhs provides for constructing 2.226 Kms of drains of sizes 1.50 m to 4.00 m wide and reconstruction of 6 existing road culverts to provide better system of Improvement as prier the study. The provision as per the NKUSIP for storm water drainage for Raichur is Rs 345.00 lakhs. Following are the works proposed under this scheme.

2..3.4 WORKS PROPOSED UNDER THIS PROJECT

1) Nalla no 4. The existing drain from the overflow point of Aam Talab (00.00Ch) to Basaveshwara circle (Ch 1277m) is lined and needs no repairs. From Chn 1277 to Ch 1577 up to the railway culvert there is no lining and is of varying width and hence has to be provided with side walls and bed. From Chn 1577m it is proposed to divert the existing alignment to avoid passing through private land. It is proposed to construct a new drain from this point parallel to the railway track for a length of 876 m so as to connect to primary drain no 3, near the main railway culvert which finally leads to Manchalapura Tank. The total length of the proposed construction of this drain is about 1176.50 Kms.

2) Nala no 3. This is a built up drain, starting from Bombay Company and Farooque Oil mill and flowing through Harijanwada, Maddipet, Basavannabavi, Goushala road, Siya talab and terminating into Manchalapura tank. The width is 4 to 5 m and length is about 3 km. The direction of flow is from east to west. The lining from Chn 0 to Chn 1002 is found to be good. From Chn 1002 to Chn 1232m, from Chn 1232 to Chn 1445 and 1601 Chn 1888 m it is proposed to undertake lining and reconstruction works of 1.75m X 1.50m (230m long), 4.0X1.80m (500m) sections and thereby improve the entire length of this Nalla within the Town. Since Nallah no 7 flows into Nallah 3 in Neerbhavi Kunta it is proposed to have a section of 4.0x1.8 for Nallah 3 to accommodate the flow from Nalla 7.

NKUSIP (Package IV – Bellary) Tranche I Sub Projects in Raichur Town IEE Report

3) Nalla No.5: This nallah starts from Amit Ali Rice Mill, flows through Bruhasthwarpet pet on Gunj road to Sukhani colony and joins Nallah No.3 in Siya Talaab (Mukthal pet). The direction of flow is from southeast to northwest. The total length of this nallah is 1037 m, out of which 737 m from Chmn0 to Chn 737 is lined and found good. From Chn 737 to 1037 it is proposed to undertake lining and bed construction and link the Nala with Nala no 3. Hence the length of construction [proposed is 276 m with a box culvert at Chn 868m. 4) Nalla No-7: This nallah starts from Devinagar Gadwal road and flows through Neerbhavi Kunta and joins the main primary drain no 3 in Neerbhavi Kunta. The length of this drain is about 1710 mts. The direction is from East to West. The entire drain is unlined. It is only proposed to take up lining for a length of 44 m, from Chn 1666 to end point at 1710m, near the junction with Nala 3 in Neerbhavi Kunta, for improving the flow at the joining point. The above works also includes the construction of required cross drainage works.

2.5.4 Urban Roads Improvement

The improvements would increase the effectiveness of the road space by providing improved riding surfaces and removing impedances to the flow of traffic. This improvement reduces the effort or inconvenience of travel between the origin of the traveller and the destination offering these activities. Benefits of road improvements comprise (i) reduced dust generation due to improved road surface; and (ii) optimum fuel consumption due to improved vehicle speeds.

. 6 2 Investment Program Alternatives

The environmental suitability of the proposed components are judged through the selected location and proposed process/technology during both the construction and operation phases. The interaction and the level of interference with the surrounding land use determine the environmental sustainability of the Investment Program components. The following table shows environmental suitability of the selected alternatives.

KUIDFC 30 Span & Voyants

NKUSIP (Package IV – Bellary) Tranche I Sub Projects in Raichur Town IEE Report

Table 12 Investment Program Alternatives

Sub- Suitability of Selected Alternative Component Sewerage The best alternative for the sewerage system is to design the system based System on gravity flow. The proposed gravity system will be simple in operation and require less man power and importantly does not require energy. The natural gravity is utilized to run the system.

In terms of location of the treatment plants, as it is proposed to reconstruct and upgrade the existing plants, no alternative sites were identified. However, these sites are ideally located away from habitation and were selected based on the topography.

There are number of options to treat the wastewater to the standards of either for river discharges or for land disposal after treatment. The options like attached growth aerobic or anaerobic systems or suspended growth systems can be adopted. However, as the existing STPs are stabilization pond based plants and hence it is proposed to upgrade these STPs with FAL technology.

Storm water Only rehabilitation of existing drains is proposed and therefore no alternatives drainage were considered. However, the best alternative of gravity flow system is retained.

Water Supply The best alternative for water supply is to design the system based on gravity flow. However, due to topography and required pressure at the consumer end, the system is designed as partly gravity and partly pumping.

As the existing system losses are at higher side, reducing the losses and improving the efficiency of the system is identified as one of the important component under NKUSIP. Developing of a pumping station at the existing intake is proposed. This is necessitated as the existing pumping capacity is not sufficient. It is proposed to use high efficiency pumps to reduce the energy loads. Roads up Roads considered for improvement are selected based on the traffic and its gradation importance in connectivity and environmental and social issues involved.

No acquisition of land/structure is involved in the road improvement. It involves no tree cutting.

DESCRIPTION OF THE ENVIRONMENT

3.1 Environmental Profile of Raichur

3.1.1 Introduction 0 0 Geographically, Raichur is situated at 15 12’ North latitude and 77 21’ east longitudes. The two important Rivers, the Tungabhadra and the Krishna form the two boundaries of the district; these rivers flow at around 20 and 30 km respectively from the district head quarter town of Raichur. The town is an important regional centre in the state of Karnataka and is one of the important centres for production of cotton in South India. Raichur is surrounded by vast agricultural lands and is major trading centre for groundnut, paddy, rice and the other agricultural produces.

3.1.2 Physiographic

The town’s general topography is plain with Rocky hills. The soil of the town is characterised by block cotton soil in the west of the railway line and the remaining area consists of red rocky soil.

3.1.3 Seismology

As per the Seismic Zoning map of India, the Raichur town falls under the Zone II, which is the lowest earth quake risk zone in India. This zone is termed as “low damage risk zone”.

3.1.4 Climatic Conditions

The town receives Southwest monsoon during the period of June to September and the period between the months of October and November can be termed as post monsoon months. The town experiences scanty rainfall and the long term annual average rainfall is 755 mm. The rainfall is confined and about 70 percent of the annual rainfall is received during the months of June to September. The region is continuously experiencing below normal rainfall during the last four years. The actual rainfall received in the year 2004 is 679 mm with a departure of -10 percent from the normal. However, the year 2004 can be termed as better of considering far below normal rainfall years of 2002 and 2003.

The relative humidity varies from 25 to 80 percent, and is generally higher during the southwest monsoon season ranging from 52 to 80 percent. The following table shows the climatologically details. the wind blows predominantly from west and southwest during monsoon period of June to September while from November to March the predominant wind direction east. The winds are light in this region. Most of the winds occur in the range of 1-5 kmph; and during the monsoon, winds are in the range of 6-11 kmph also occur.

3.1.5 Water Bodies

Tungabhadra flows at a distance of about 20 km from the town. Two water bodies, the Manchalapur tank and Aam talab, are located in the town. Almost 80 percent of the area drains into Manchalapur Tank and the remaining in to the Aam Talab. Due to low rainfall in the area, the tanks are almost dry. As the rainfall is confined to short period of the year, these streams carry wastewater for most parts of the year and eventually pollute the Manchalapur Lake and Aam Talab. At present, these lakes are polluted and filled with wastewater. Due to lack of adequate sewerage system, the wastewater enters these streams.

3.1.6 Groundwater

In addition to the municipal water supply in the town, sizable population also depends on groundwater resources; in the extension areas and uncovered areas the groundwater is only source of water. The depth of water table is medium and is in the range of 8 m to 14 m; however, due to low yield of top aquifer, the depth of wells are generally deep i.e. more than 50 m. Table -15 shows the fluctuation in the depth of water table at Raichur. There are no major fluctuations recorded during last three years.

3.1.8 Flora and Fauna

There are no forest areas in and around the town and there are no sensitive environmental features such as National Parks, Wetlands, and Biosphere Reserves in the Raichur District. No endangered/protected species of either flora or fauna are found in the town and their surroundings.

3.1.9 Socio Economic Characteristics

Demography: Raichur has witnessed a remarkable increase in the population. It has grown from 169,488 in 1991 to 205,634 in 2001, registering a decadal growth rate of 36 percent. Extending to a total area of 41.23 sq. Km inhabiting little more than 0.2 million population, the gross density of the town is 4,987 persons per sq. km. Mukthalpet,

Maddipet, Arab Mohall, Androon Quill, Baron Quill, Mangalwarpet, Gajgaripeth and Somwarpet are thickly populated areas of the town. Due to lack infrastructure facilities such as water supply and sewerage in the fringe areas, the people prefer to remain in the central served areas rather than move to the town periphery.

The sex ratio (2001) in Raichur was 945, which is slightly lower than the district urban average of 949 and slightly more than the State urban average of 941. The town has higher and literacy rate in comparison with the district. The respective figure in 2001, for Raichur was 71.5 percent and that of district and State urban literacy was 67.6 percent and 71.4 percent.

Economic Base . Raichur is a focal point for trade and commercial activities in the region. There are eight large and medium scale industries in the taluka. The town has a sound industrial and as well agricultural based development. Cotton and rice are the main exports of the town. Raichur town has the most prestigious and profit making power generation unit, Raichur Thermal Power Station with 6 units each of 210 MW capacity which is running almost 100 percent capacity. As the power plant is located away from the town, interference with the town air quality is not observed, which is evident from the air quality data of the town.

Poverty . Urban slum dwellers in Raichur constitute 38 percent of the town’s population.

3.1.10 Cultural and Historic Places

Though the Raichur region has great mythological importance and rich history, there are no protected monuments in the town. Weapons and implements made of stone are found in villages called Maski, Karadkal and Kallur. During the 3rd century, the district was ruled by

KUIDFC 38 Span & Voyants

SCREENING OF POTENTIAL ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

Potential Environmental impacts of the proposed infrastructure components are presented in this section. Mitigation measures, to minimize/mitigate negative impacts, if any, are recommended along with the agency responsible for implementation. Monitoring actions to be conducted during the implementation phase is also recommended to reduce the impact.

Screening of potential environmental impacts is categorized into four categories considering Investment Program phases: location impacts and design impacts (pre construction phase), construction phase impacts and operations and maintenance phase impacts.

(i) Location impacts include impacts associated with site selection, and include loss of on- site biophysical array and encroachment either directly or indirectly on adjacent environments. It also includes impacts on people who will lose their livelihood or any other structures by the development of that site.

(ii) Design impacts include impacts arising from project design, including technology used, scale of operation/throughput, waste production, discharge specifications, pollution sources and ancillary services.

(iii) Construction impacts include impacts caused by site clearing, earthworks, machinery, vehicles and workers. Construction site impacts include erosion, dust, noise, traffic congestion and waste production.

(iv) O & M impacts include impacts arising from the operation and maintenance activities of the infrastructure facility. These include routine management of operational waste streams, and occupational health and safety issues.

Screening of environmental impacts has been based on the impact magnitude (negligible/moderate/severe – in the order of increasing degree) and impact duration (temporary/permanent). The following table shows the screening of impacts; N/T represents the lowest impact while S/P represents the highest impact. Numerator represents the Degree of Impact and denominator represents the Duration of impact.

INSTITUTIONAL REQUIREMENTS AND ENVIRONMENTAL MONITORING PLAN

5.1 Institutional Requirements

Karnataka Urban Infrastructure Development & Finance Corporation (KUIDFC) is the nodal executing agency (EA) responsible for implementing NKUSIP. Investment Program implementation activities will be monitored by KUIDFC through a separate Investment Program Management Unit (IIPMU), which will be set-up within KUIDFC.

Implementing Agency (IA). Implementation Agencies (IA) will oversee sub-project component implementation at the sub-project towns, where the Investment Program ULB will implement sub- project components. The responsibilities of the IA shall include (i) carrying out detailed surveys, investigations and engineering designs of individual infrastructure components; (ii) tendering, evaluating bids and awarding works, contract administration, supervision and quality control; (iii) measuring works carried out by the contractors and certifying payments; (iv) conducting public awareness campaigns and participation programs, (v) carrying out environmental assessments; and (vi) preparing monthly reports. The Investment Program Consultants (PC) will assist the Investment Program ULB in all the aforesaid activities; in the case of other IAs, the PC shall proof check designs and quality check construction quality.

` Thus, the responsibility fulfilling environmental requirements of GoI/GoK (for the project- components of STP,) and conducting required level of environmental assessment as per ADB guidelines lies with the borrowing ULB. The Investment Program Consultants will assist the ULB in this regard. The IEE reports prepared by ULB will be reviewed by the IPMU as per the ADB’s Environmental Guidelines and forwarded to ADB for review and approval. In case of IEE reports, the ADB could delegate approval of IEE reports fully to the IPMU after reviewing the first two reports. However, all the IEE reports shall be sent to ADB for approval.

The mitigation measures identified through IEE are incorporated into the project cycle. Mitigation measures, which are implemented by the Contractor, shall form part of the Contract Documents. The other mitigation measures are undertaken by the ULB (itself or in assistance with Investment Program Consultants) as specified in the IEE.

Chapter - VII FINDING AND RECOMMENDATION

7.1 Findings

Based on the screening of environmental impacts, all the proposed sub-project components in Raichur are found to be environmentally acceptable and therefore able to proceed to the implementation phase. In most cases, particular environmental issues identified are those that are typical for the type of component, and a range of proven mitigation strategies exist to address them. Table 27 indicates the environmental consideration of the proposed infrastructure components.

Table 27: Environmental Issues of Infrastructure Components Inf rast ructure Environmental Impact Issue Envir onment al Compon ent Mit igat ions Sewage treatment Appropriate mitigatio n measures plant and sewera g• Air dispersion modelling for odour as suggested up gradation • Construction and operation impacts Solid waste • No significant issues N/a. mana gement Water Supply • Sludge handling and disposal Appropriate mitigatio n measures Rehabilitat ion • Construction and operation imp acts as suggested Upgradation of r o• Disturbance to hawkers and vendors Appropriate mitigatio n measures and traffic system • Construction and operation impacts as suggested

As described above, most impacts are relevant to typical construction and operation. The important sets of mitigation measures, which are relevant to most of the components, include preparation of activity plans using appropriate mitigation measures identified in the earlier sections. These activity plans include:

• Sludge Management and Disposal Plan (to address sludge handling and disposal impacts at the STP) • Health Risk Plan (to address the health related impacts of the STP workers and sanitary workers)

These activity plans should be prepared by the Investment Program Consultants as a compendium of the relevant mitigation measures identified in earlier section. They should form part of the contractual arrangements with construction contractors, or directly implemented by the CMC as facility operator, as required ‘Work Practices’.

NKUSIP (Package IV – Bellary) Tranche I Sub Projects in Raichur Town IEE Report

7.2 Recommendations

It is recommended that the IPMU should be involved in monitoring the implementation of those components that are critical to acceptable environmental performance of the component. Owing to the location of proposed facilities and geographical setting of the town/region as a whole, no major impacts envisaged from any of the proposed sub- components projects in Raichur. Most of the impacts could be mitigated with sound design and therefore the design stage becomes crucial. In view of this importance, the PMU is delegated with the monitoring responsibility of the design stage to ensure the environmental sustainability of the NKUSIP.

CONCLUSIONS

The proposed components should proceed through to design and implementation, subject to mitigation measures and monitoring programs identified in the IEE which will be updated detailed during detailed design stage. Owning to the nature and scale of the proposed components in Raichur it may be emphasized that the present IEE, which identifies potential impacts and suggests appropriate mitigation measures, is sufficient enough to safeguard the environment. There are no significant adverse impacts, which are irreversible or may lead to considerable loss/destruction of environment, envisaged. All the impacts are simple and moreover proven mitigation measures exists to minimize/mitigate the same. Hence, no further study such as an EIA is required.
