I. INTRODUCTION 1. Kolkata Municipal Corporation (KMC) is the Executing Agency (EA) for implementing the Kolkata Environmental Improvement Project (KEIP or the Project) with financial assistance from Asian Development Bank (ADB) since 2002. The Project consists of the following six parts or components (RRP, 2000): Part A: Stakeholder Consultation Process Part B: Sewerage and Drainage Improvement Part C: Solid Waste Management Part D: Slum Improvements Part E: Canal Improvements Part F: Implementation Assistance and Capacity Building
2. The Project Preparatory Technical Assistance (PPTA) had prepared an Initial Environmental Examination (IEE) report in 2000 designating the Project as Category B. During detailed design and implementation of the Project since then, the physical scope and design of the Project have been modified, and approved by the ADB. These include construction of new sewerage and drainage (S & D) network in borough VII and discharge of untreated sewage from S & D works under the Project in boroughs VII, XI and XII into the existing Dry Weather Flow (DWF) channel for eventual natural treatment in the fisheries of the East Kolkata Wetlands (EKW), an ecologically sensitive area listed as a Ramsar site. Accordingly, the original IEE of 2000 had been revised and updated to screen and assess potential environmental impacts and appropriate mitigation measures had been proposed. The overall IEE showed that the Project would have a positive impact on the environment of the project area particularly on terrestrial habitats, through improved sewage and drainage facilities, reducing flood damage due to water logging during monsoon, improving the local environment and enhancing institutional capacity for providing improved civic services in the targeted areas of Kolkata and especially in the selected slum areas. The potential adverse impacts on the environment are perceived to be localized, short term, non significant, and can generally be mitigated. The mitigation measures have been adequately spelt out in the revised IEE including the EMP and component wise IEEs. The summary IEE developed for the Project was publicly disclosed on ADB website in August 2006.
3. Since a part of the Project extends into the environmentally sensitive EKW area, the revised KEIP has now been categorized as B sensitive. As such an environmental management plan (EMP), as per requirements of Environment Policy of ADB, 2002, ADB’s Environmental Guideline, 2003 and ADB’s Environmental Operation Manual, 2006, had been developed. Meanwhile a Project Specific Study (PSS) by Dr Tim Wrigley and Dr Asis
1 Mazumdar of School of Water Resources Engineering, Jadavpur University has been carried out as part of TA 4814 IND (component TA for capacity building for the protection of EKW). Findings of the PSS specifically indicate that no additional STP is required to be constructed due to the additional sewage to be generated by KEIP that is proposed to be conveyed and naturally treated in the EKW.
4. With taking up of the canal re excavation work in the EKW areas, the existing IEE and EMP were further modified with add on data as required in August, 2010. Such re excavation work received also the concurrence of East Kolkata Wetlands Management Authority (EKWMA)
5. The present EMP implementation report relates to the progress of implementation of the provisions of EMP of KEIP during the last six months (January June) of 2012 in respect of various work components of Part B, Part C, Part D and Part E in which civil constructions are involved. The Stake Holder Consultation Process (Part A) is an important component of the Project in all phases of implementation of components of KEIP involving civil construction. Such consultations, during the design stage, have provided important inputs for addressing environmental concerns of the stakeholders and have been duly considered. During the construction phase, more frequent stakeholder consultations at work site levels have been carried out. These consultations were held to confirm that the implementation of the EMP to overcome the perceived adverse environmental impacts, identified during the design stage, is being adequately and effectively addressed. The Implementation Assistance and Capacity Building of KMC (Part F) is another important component of the Project that is being implemented through various studies and consultations with DFID, UK funds. Implementation of the EMP will be facilitated by such capacity building of the KMC during the operation and maintenance phase.

E. Construction of Housing Colonies 13. There were work packages related to construction of housing colonies for relocation of canal bank dwellers as part of R & R plan of KEIP. Construction activities (civil and non civil) in respect of these housing colonies have been completed.
III. REPORT ON EMP IMPLEMENTATION Induction of contractors on implementation & monitoring requirements
14. Consequent upon the award of any contract and during the construction activities, contractors are made aware of the basic provisions of EMP as related to their works. These were accomplished through instructions by the site engineers and Senior Construction Supervisors of Design and Supervision Consultants (DSC), KEIP. Compliance reports of contractors prior to commencement of works 15. Works related to construction/refurbishment/augmentation of the pumping stations commenced after the design parameters were established so as to prevent any flooding of the facility due to inadequate space, capacity and pumping requirements. Works related to laying of pipes under S & D component started only when the site management plan including traffic diversions, if any are finalised and explained to the contractors. 16. Works related to canal improvements commenced only when the major relocation of canal bank dwellers for the selected stretches is completed. Where canal bank dwellers could not be relocated, adequate design to prevent bank collapse and/or damage to dwelling units has been adopted. Weekly construction reports of contractors and DSC
17. Weekly reviews of all construction activities with emphasis on mitigation measures of potential environmental impacts being undertaken by the Contractors have been taken by the respective Senior Construction Supervisors. Spot flying checks on the construction sites to ensure overall quality control including environmental and social requirements are being made by Team Leader (TL), DSC.
7 Training of contractors on mitigation of unexpected adverse impacts 18. Mitigation measures for any unexpected adverse impacts being faced are formulated by DSC and implemented by Contractors under the supervision of site engineers of DSC as soon as they crop up and reviewed about their efficacies weekly by the Senior Construction Supervisors of DSC.
Monthly monitoring report
19. Major Package wise monthly reports are being prepared by Senior Construction Supervisors of DSC in consultation with Environment Specialist of DSC. These reports are available in the office of DSC. Six monthly progress report of EMP implementation 20. Six monthly review and report of EMP implementation is being developed by Environment Specialist of DSC based on the feed back from and in consultation with Senior Construction Supervisors of DSC and limited site visits also incorporating the results of the required sampling, laboratory analysis and measurements. The present EMP implementation report (January June, 2012) corresponds to eleventh six monthly report of KEIP. Institutional Strengthening and Training
21. The recently established East Kolkata Wetlands Management Authority (EKWMA) of Government of West Bengal (GOWB) had engaged M/S Wetland International for the development of an EKW EMP and they have submitted their reports outlining the proposed management plan of EKW. The proposed interventions by KEIP in the form of re excavation of some of the canals of EKW have been planned keeping in consideration the recommendations of EKW EMP and EKWMA. 22. KMC had established an environment management cell (EMC). The EMC is to play an advisory and overall coordination role for KMC and KEIP to ensure that agreed mitigation measures and monitoring are being carried out. Environment has been formally introduced as a subject in the portfolio of one of the Members Mayor in Council (Policy making Body in KMC). A Chief Engineer rank officer is the Nodal Officer of the EMC. At KEIP Mr Kalyan Ghosh, Special Officer (Coordination) and Mr Subhojit Dasgupta, Dy Chief Engineer have been named as the Environmental Coordinators of KEIP. There is a fully functional Central Water Testing Laboratory in KMC. There is also a dedicated water testing facility at Palta Water Treatment Plant. Further the ponds and water bodies in KMC area are being cleansed and preserved in keeping with the Inland Fisheries Act and the West Bengal Town and Country Planning Act. The EMC is looking into all this.
8 Statutory Clearances/Approval Status and Loan covenants 23. Environmental Clearance (EC) of Nonadanga housing for rehabilitation of canal bank dwellers has been accorded by the State Level Appraisal Committee. The follow up ‘Consent to Establish’ certificate from WBPCB for the housing colony has also been obtained. The Consent to Operate certificate has been obtained on 10.5.2012 (copy enclosed).
24. Consent to establish certificates for the three STPs under refurbishment of KEIP have been duly obtained. Consent to Operate certificate in respect of South Suburban East (SSE) STP was obtained in 2009 and a renewal has also been granted till end of May, 2011. As the SSE STP has already been handed over to KMC subsequent environmental obligations are being met by KMC.
25. Consent to Operate application in respect of Garden Reach STP has been issued by WBPCB on 26.12.2011 but was received by KEIP on 9.3.2012 (copy enclosed). Consent to Operate certificate for Bangur STP has been filed with WBPCB on 21.11.2011; The Plant was inspected by WBPCB officials on 29.11.2011. Additional information as demanded by WBPCB has been filed on December 1, 2011. Further information as requested by WBPCB on 13.6.2012 has been filed on 26.6.2012. The matter is being pursued.
26. EKWMA has accorded permission to carry out canal rehabilitation works falling in EKW areas and reconfirmed their permission after recent notification of Wetlands (Conservation and Management) Rules, 2010.
27. The main components of loan covenants for 1813 IND and 2293 IND are as follows:
Processing and disposal of waste water pursuant to the prescribed standard – Currently KMC is discharging treated waste water from the refurbished SSE STP and Garden Reach in to respective canals. The treated effluent met the standard stipulated by WBPCB while granting the consent to operate certificate for the STPs.
Submission of report on annual environmental and safety monitoring program The Project is regularly submitting a six monthly EMP Implementation report to ADB detailing the required environmental and safety monitoring
Completion of City Sewerage and Drainage Master Plan – The S & D Master Plan has been prepared.
Alternative treatment of sewage – The Project has opted for natural treatment of sewage from Borough VII and Parts of Borough XI and XII through the fisheries of
9 EKW. The option has been exercised based on the provisions of EKW Management Plan prepared by the EKWMA and based on the findings of a project specific study by the Project covering the laid down objectives
IV. ENVIRONMENTAL CONDITIONS A. Sewerage and Drainage Improvement (i) Construction of combined S & D network
28. Construction activities have impacted the local environment in some sites mainly in the nature of inconveniences to the residents/passer bys. These inconveniences are transient in nature and have disappeared once the construction phase is over. Many of the inconveniences have been mitigated to the extent practicable so that their intensities are minimized and/or shortened in time and there is no adverse permanent impact on the environment. Some of these inconveniences are to be accepted (for which informal public awareness campaign has been taken up) for a short period of time for bringing in a permanent improved environment once the construction phase is completed.
(ii) Construction and augmentation of pumping stations 29. Construction work of new pumping stations during the period continued with activities like installation of new pumps in some cases and well sinking and other civil works in some other cases. In some packages the construction work has advanced to completion stage with informal inauguration of the pumping stations. Environmental conditions at the construction sites remained mostly unchanged due to low intensity construction activities. On the other hand, better drainage in the catchments of the pumping stations is likely to bring in improvement in environmental conditions.
(iii) Disposal of waste water into DWF channel
30. Disposal of additional waste water in to DWF channel will commence when pipe laying works, house connections and construction and commissioning of pumping stations in the designated catchments under the KEIP are completed. Environmental condition around the DWF channel therefore was not impacted during the period due to the Project. (iv) Construction of new and augmented/refurbished sewerage treatment plants (STPs) for discharge of treated effluents in to the drainage canals.
31. Construction activities related to refurbishment of South Suburban East Sewage Treatment Plant have been completed. The facility has been handed over to KMC for operation. Completion of construction has brought in the expected improvement in local environment. Civil construction activities related to refurbishment of the other two STPs (Bangur and Garden Reach) have been completed. Initial desludging operations had brought
10 out large volume of sludge that had been disposed, after dewatering, in low lying areas within the premises of the STPs and covered with suitable material later on. The plants are on trial run. B. Solid Waste Management 32. No activity is to be reported under this component during the period under review. C. Slum Improvement 33. The environmental conditions of selected slums have improved after the planned constructions of infra structural facilities are completed.
D. Canal Improvement Works 34. With the relocation of canal bank dwellers (wherever required), re excavations of canals and bridge constructions, the canal bank areas and their surroundings are poised for an improvement in environmental conditions with better conveyance of storm/dry weather flows, and improvement of drainage in catchments and elimination of ugly shanties (wherever carried out) along canal banks. Such displaced canal bank dwellers are being rehabilitated with housings having basic civic amenities for a healthy and dignified living. The excavated silts are non hazardous and are being disposed at pre arranged approved sites where no adverse impacts on environment are expected. Precautions have been taken for stabilising the canal banks through engineering measures wherever required. In EKW areas, wet excavation in many places is in progress and work is being carried out in close liaison with local people/authorities/organisations.
11 V. MEASUREMENT OR SAMPLING UNDERTAKEN AND MONITORING RESULTS Measurements in EKW areas 35. An intensive environmental monitoring program has been initiated in the EKW area from 2010 in order to closely monitor any sign of adverse impact on the environmental parameters due to intervention by KEIP works. They include the following: Ambient air quality 36. Ambient air quality has been measured at four locations in EKW area for one 24 hour period (split in 3 shifts of 8 hours) in each month. Concentrations of Respirable Particulate
Matter (RPM), Suspended Particulate Matter (SPM), Sulphur Dioxide (SO2), Oxides of
Nitrogen (NOx), Carbon Monoxide (CO) and Lead (Pb) in SPM have been monitored following BIS 5182. The results are tabulated in Appendix 1. Both RPM and SPM concentrations are relatively high and annual concentrations of RPM are likely to exceed the 3 respective notified prescribed standards (time weighted annual average PM10 = 60µg/m ) of Central Pollution Control Board (CPCB). Most of the values of SPM in the second shift are relatively lower than other shifts. The highest quantity of RPM has been observed in station A4 (Khanamba Bani Vidyalaya) in the month of January. Such high concentrations are the result of long distance migration of the above pollutants from the Kolkata city proper lying to the west of EKW. Although some values of NOx concentration are above 30 µg/m3 of air, concentrations of SO2 and NOx are relatively low. It has also been found that NOx values in all six months of Station A4 are within the respective standard limit. Annual concentrations of these parameters are likely to be within respective limits of notified prescribed standards (SO2 3 3 = 20µg/m and NOx = 30µg/m air in eco sensitive areas) of CPCB. Concentrations of CO and Pb were always below the respective detection limits. Canal silt quality after excavation 37. As part of work contract packages of canal excavation in the EKW area, Contractors have provided analysis (of selected parameters) of canal silt along stretches of canals. The results are tabulated in Appendix 2. The concentrations of analyzed parameters (including heavy metals like Pb, Cd, hexavalent Cr, Hg, As, and Ni) are within the respective prescribed limits of Hazardous Wastes (M, H & TM) Amendment Rules 2008. Water quality of canals 38. Water quality analysis (Appendix 3) has been carried out for canals flowing within KMC area and for those flowing within EKW area.
12 Canals flowing within KMC area: 39. The canals flowing within KMC area are mainly Storm Water Fed (Belaghata Khal, Circular Canal, Keorapukur Khal, Muni Khali Khal, Newcut Canal, Tolly Nallah, T.P. Canal). Analysis of water from these canals shows the presence of very high turbidity, high TDS. Dissolved Oxygen level is higher than 4mg/lit in most of the canals and in most of the months. BOD values are within the range of 15 120 mg/lit. COD and oil and grease values are all within the required permissible limit (250mg/lit for COD and 10mg/lit for oil and grease). Heavy metals like Chromium (+3 and +6), Arsenic, Cadmium, Copper, Nickel and Mercury are present below their respective detection limit. Iron and Zinc concentrations are around 1.0 mg/lit and Sulphide concentrations are within 1.5 9.5 mg/lit. All of the canals have very high faecal coliform count (around 106 MPN/100ml). Canals flowing within EKW area: 40. The canals flowing within EKW area are mainly Sewage Fed (Bidyadhori connecting, canal near Bhojarhat football ground, canal near Chandipur and canal near Bantala). The pH values of these canals are within 6 8. TDS and Turbidity values are very high in all six months. DO values are above 4 mg/lit in all canals except Bidyadhari connecting canal and the canal near Chnadipur in two months. BOD values range within 23 50 mg/lit and only Bidyadhari connecting canal shows BOD level less than 30 mg/lit in all months. COD and oil and grease values are within their required permissible limit. Heavy metals like Chromium (+3 and +6), Arsenic, Cadmium, Copper, Nickel and Mercury are present below their respective detection limit. Iron and Zinc concentrations are around 1.0 mg/lit and Sulphide concentrations are within 1 6 mg/lit. All of the canals have very high faecal coliform count (around 106 MPN/100ml). Ground water quality 41. Ground water from 8 tube wells have been analysed and the results are tabulated in Appendix 4. Concentrations of fluoride, lead, cadmium, arsenic, chromium (+3 and +6), mercury, phenolic compounds, cyanide and total coliform are below the respective detection limits. Total dissolved solid concentration ranges in between 810mg/l to 1120 mg/l with corresponding high values of total hardness (varying between 192 mg/l and 350 mg/l), sodium (36.5 mg/l and 325 mg/l) and chloride (in between 136 mg/l to 328.13 mg/l). Iron concentration is high varying between 0.80 and 21.1 mg/l. Noise Level Measurement 42. Noise levels in dBA have been measured at the periphery of several work sites of the KEIP where civil construction is going on (Appendix 5). There are two sets of measurements:
13 one corresponding to situation when the work has been stopped and another when the work is in full force. The amount of noise added by the construction works could be estimated from the difference in values that bear direct correlation to the type and number of machineries that are in operation. 43. Elevated noise levels can not be avoided at work sites but were often of short and/or intermittent duration and during the day time only. However, total dosage to the work men was within the prescribed limit of occupational health and safety. Also necessary protection measures to the work men and those who are working near the site as per rule have been enforced. Within the work site the time averaged ambient noise level in dB (A) is from 61.05 and 69.5 (mean value) depending upon the type and volume of traffic on nearby road. At sites where activity was going on at the periphery of work site the time averaged noise level in dB (A) (mean value) is from 69.85 and 89.45. Considering that ambient noise level is relatively high in typical congested mixed residential commercial areas of Kolkata with high multi modal traffic noise, the measured ambient noise levels, where exceed the standard, are to be accepted. VI. FINDINGS ON THE COMPLIANCE STATUS 44. The implementation including monitoring as planned in the EMP has been carried out at all major work sites of the KEIP. The works are related mainly to construction phase only. The daily observations that are required to be made as per list of monitoring agenda were noted each day by the site engineers of the Contractors and DSC in their Construction records. These were summarized on a weekly basis and were reviewed by the respective Senior Construction Supervisors of DSC and extra remedial measures, if required, were implemented. The extra remedial measures are listed in Chapter VII. Major package wise monthly reports were prepared by the respective Senior Construction Supervisors that have been used by the Environment Specialist of DSC to develop the six monthly report of EMP implementation of KEIP. 45. The above structured approach for the period January June, 2012 has ensured that the provisions of the EMP have been enforced and complied with. The potential adverse impacts have been mitigated to the extent possible by continuous and timely measures as provided in the EMP. In a few cases unexpected and unavoidable situations (like water logging, difficulty faced for movement and access to houses in narrow streets with no alternate pathways, etc) have developed leading to temporary inconveniences that have been mitigated to the extent possible by taking timely appropriate measures. Sewerage & Drainage network
14 Construction Phase
46. Summary observations of monitoring carried out during the Construction Phase during January June, 2012 are given below item wise: i. Soil erosion & surface run-off prevention Daily visual inspections have been carried out by DSC site supervisors at all running work sites to ensure exposed surfaces are resurfaced and stabilized rapidly by the Contractors. Timely precautionary measures were taken to prevent soil erosion and “landslide” in a few cases where such measures were necessary. ii. Prevention of dust nuisance There was no dust nuisance during the wet periods. Daily visual inspections have been carried out by DSC site supervisors at all running work sites to ensure (a) light water spraying on loose and fine debris whenever necessary during dry periods, (b) use of masks / goggles by workmen whenever necessary & (c) covered transport of excess material whenever necessary. There was no record of heavy fugitive dust emission in the work sites. It is to be noted that site conditions did not allow use of much of heavy equipment. Generation of dust was, therefore, on the low side.
iii. Disposal of silt and excess soil Monthly visual inspection of sites and delivery records of the Contractors have been carried out by DSC site supervisors to ensure that timely and adequate disposal of silt and excess soil has been undertaken by the Contractors at pre agreed and pre approved sites. There was no case of unnecessary silt / soil accumulation at work sites. iv. Prevention of soil, ground and/or surface water contamination from contaminated silt No contaminated silt arising out of cleaning/dismantling of existing sewage lines has been excavated out during the present construction phase. v. Vehicular and Construction noise pollution mitigation Sound level monitoring has been carried out at different running work sites. The data given in Appendix 5 bring out that the noise levels due to construction activities were elevated some decibals over the ambient noise where works were carried out manually. Where work is in suspension the ambient noise levels are within acceptable limit. vi. Relocation of utility services Intersection of major utility lines during trenching/excavation for drainage network was avoided in most cases. Diversions of water supply lines and electrical lines have been carried out observing the required formalities and with the consent of affected people.
15 vii. Prevention of water logging / flooding during trenching Daily inspection at all running work sites has been carried out by DSC site supervisors to check water levels in the trenches. Timely dewatering was carried out as required. However, during wet periods some areas experienced temporary water logging due to high intensity rainfall and due to impaired and insufficient drainage. Necessary draining and pumping of water logged areas were taken up to the extent feasible by deploying additional pumps. viii. Traffic management Partial/full closure of any public road including temporary diversion was done in co ordination with the police authorities. The situation was reviewed daily by DSC site supervisors with the Contractors to minimize inconveniences to the local people. Safe passage for bicycles and pedestrian traffic was always maintained. Cases of major traffic closures/diversions were in the places as mentioned in Table 5. Table 5.

16 ix. Health and safety of work force Daily visual inspection was carried out by DSC site supervisors to ensure that Occupational Health & Safety standards were followed by the Contractors.
x. Environmental health & safety at construction camp sites A safety, health and environmental plan were submitted by each Contractor on acceptance of the work order detailing the provisions being made under the Plan. The Plan in each case provided for, amongst other things, temporary labour camps with flush latrines. In addition available pay and use toilets came handy for the camp sites in some places. On the whole the camp sites did not pose any threat to environmental health and safety in the area. DSC site supervisors made daily visual inspections. xi. Conservation of places of cultural importance There was no case involving places of cultural importance falling along S&D network excavations. Pumping Stations Construction Phase 47. Summary observations of monitoring carried out in the Construction Phase during January June, 2012 are given below item wise:
i. Soil erosion & surface run-off prevention Daily visual inspections have been carried out by DSC site supervisors at all running work sites to ensure working surfaces do not remain exposed and unstable after completion of the construction work.
ii. Prevention of dust nuisance There was no dust emission during the wet periods. Daily visual inspections have been carried out by DSC site supervisors at all running work sites to ensure (a) light water spraying on loose and fine debris whenever necessary during dry periods, (b) use of masks / goggles by workmen whenever necessary & (c) covered transport of excess material whenever necessary. There was no record of fugitive dust emission in the work sites. It is to be noted that site conditions did not allow use of much heavy equipment. Generation of dust was, therefore, on the low side.
iii. Prevention of soil, ground and/or surface water contamination from contaminated silt No contaminated silt was excavated out during the present construction phase.
17 iv. Vehicular and Construction noise pollution mitigation Dewatering of trenches by pumps and employment of mixture machine were sources of relatively elevated noise level at the work sites. However, noise levels as measured progressively away from the work zones show considerable reduction thereby indicating the local people are not distressed by elevated transient noise levels at the work sites compared to the construction workers, Workmen were provided with appropriate gears for adverse sound levels at work sites wherever felt necessary. No night operations were carried out.
Sewage Treatment Plant Operation Phase 48. Safety related measures are being re looked and adequate provisions will be in place as required. Canal Improvements (Non-EKW areas) Pre-construction Phase 49. Summary observations of monitoring carried out during the Pre construction Phase are given below item wise: i. Tree replanting A large number of trees has been planned to be planted along the canal banks once excavation work is complete. ii. Relocation of canal bank dwellers Most entitled canal bank dwellers have already been moved in their respective apartments. The relocated sites/housings have improved environmental conditions with adequate sanitation and other facilities compared to the abominable environmental conditions in the canal bank shanties.
Construction Phase 50. Summary observations of monitoring carried out in the Construction Phase during January June, 2012 are given below item wise:
i. Prevention of soil erosion & surface run-off Daily visual inspections have been carried out by DSC site supervisors at all running canal excavation sites to ensure that the slopes of excavated banks were stabilized rapidly by the contractor. There were minimum dry excavation works with on set of monsoon. Many re excavation in the EKW areas was through wet excavation. Timely precautionary measures (including ballah piling and steel shoring) were taken to prevent any bank failure in case of development of any adverse situation. DSC site
18 supervisors ensured that there was no case of delayed action by the contractors causing soil erosion. ii. Prevention of dust nuisance It is to be noted that canal silt was wet when excavated. Daily visual inspections were carried out by DSC site supervisors at all canal stretches under excavation to ensure (a) light water spraying on loose dried canal silt if necessary, (b) use of hand gloves / masks / goggles by workmen whenever necessary & (c) covered transport of dewatered and semi dry canal silt. iii. Disposal of excavated silt Daily visual inspection of excavation sites and monthly checking of delivery records of the contractor have been carried out by DSC site supervisors to ensure that timely and adequate disposal of excavated silt at pre agreed and pre approved sites have been undertaken by the contractor after dewatering of the excavated silts at the canal banks. There was no case of unnecessary silt accumulation at work sites. Dry silt was transported under cover. However, in EKW areas the excavated silt was disposed along the canal banks for providing embankments and/or embankment roads. The excavated silt is non hazardous in nature for the analysed parameters with respect to limits set in Hazardous Wastes (M, H & TM) Rules 2008 as analysed from samples taken before excavation (reported in previous chapter). iv. Prevention of soil, ground and/or surface water contamination from contaminated soil The silt excavated from the canal was temporarily (in EKW areas permanently) stacked by the side of the same canal. The filtrate is therefore going back to where the water charged silt came from. This is to prevent any possible pollution of other water bodies and spilling of interstitial water during transportation to disposal sites. No statutory clearance is required for this operation more so because the silt itself is non hazardous. v. Mitigation of noise pollution Sound level monitoring has been carried out at running work sites. The data bring out that the noise levels due to canal improvement activities are somewhat high where machineries like excavators were in operation. Construction noise generation due to manual excavation work was on comparatively low side. It is to be noted that construction sites are in general away from residential areas (excluding the informal shanties of the canal bank dwellers).
19 vi. Traffic Management There was no necessity of temporary/partial diversion/closure of roads for prolonged periods during the construction phase. Traffic situation was regularly reviewed by the Contractors and DSC site supervisors. In a few cases, however, temporary diversion of short stretches of canal bank roads by providing new temporary road has been made to facilitate canal excavation. vii. Health and Safety of work force Daily visual inspection was carried out by DSC site supervisors to ensure occupational health and safety standards are followed by the Contractors. Contractors are always reminded about their obligations in this regard. Temporary labour camps have primary sanitary facilities Canal Improvements in EKW areas Construction Phase 51. Summary observations of monitoring carried out in the Construction Phase during January June, 2012 are given below item wise: i. Prevention of soil erosion and surface run-off The storage sites on canal banks were chosen and managed in such a way that there were minimum soil erosion and surface run off. Residence time of temporary storage was minimal. ii. Prevention of dust nuisance Due to wet excavation, the excavated silt was moist and therefore there was practically no dust nuisance; excess material was transported by covering iii. Prevention of contamination of surface water and ground water Excavated silt was disposed timely and adequately along canal banks to form embankments and/or embankment roads. The water coming out of the disposal sites flowed back in to the canal. Analysis of excavated silts, canal water and ground water has been carried out establishing that there is no threat of pollution to surface and ground water from the excavation work iv. Mitigation for vehicular and construction noise Dewatering by pumps and employment of mixture machine were sources of relatively high noise level at the work sites. However, noise levels as measured progressively away from the work zones show considerable reduction thereby indicating the local people are not distressed by elevated transient noise levels at the work sites compared to the construction workers, Workmen were provided with appropriate gears for
20 adverse sound levels at work sites wherever felt necessary. No night operations were carried out. It was ensured that all operations were carried out during the day time and the deployed machineries met the maintenance standard. v. Prevention of air and odour nuisance from stored excavated silt: Monitored data indicate that there are elevated SPM and RPM concentration in the ambient air in the monitored stations in EKW. As the sites are close to the main city the concentration levels are in conformity with the general trend of concentration level found in the city. vi. Ensuring health and mitigation of safety hazards for work force handling sewage charged material It was ensured that suitable safety gears were provided by the Contractor and the same was used by the workmen. vii. Mitigating safety hazards, ensuring environmental health & community safety at construction camps and sites Efforts were made for provision of proper housing, drinking water, sanitation and medical facilities, and also of adequate lighting and safe storage of construction materials by the Contractor. VII. SUMMARY OF ANY NON-COMPLIANCE AND REMEDIAL ACTIONS TAKEN S & D network construction
52. There were minor threats of deterioration of local environmental quality, mainly in terms of temporary inconveniences to residents, in a few work fronts, especially in narrow roads, for the construction of S & D network due to the following reasons: • Difficulty in ingress and egress into some houses for their respective residents due to pipe laying works in narrow roads • Bad conditions of roads due to unavoidable time lag between laying of pipe lines and road restoration work • Part closure of roads with restricted traffic movements • Short term water logging in trenches • Elevated noise levels in some sites due to • working of various construction machines • use of noisy diesel pumps for dewatering of trenches • plying of trucks in the night especially for removing excess earth and movement of construction materials
21 53. The following remedial actions were taken expeditiously mitigating the inconveniences to a large extent. • Ingress and egress to affected houses were provided as far as practicable although in some cases there were temporary restrictions on full accessibility due to non availability of alternate space. These restrictions were withdrawn expeditiously through suitable engineering measures. • Alternate traffic routes were always provided for temporary closure or part closure of roads with provisions of pathways for pedestrians and two wheelers. • Accumulated water was pumped out as and when required to the extent possible • Restoration of electricity and water supply was arranged expeditiously by pursuing the CESC and through engagement of KMC registered plumbers to undertake diversion/repair expeditiously respectively. • Elevated noise levels at work sites are to be accepted, in the cases mentioned, as these are work related noise that can not be avoided. However, proper maintenance of the equipments was enforced on the contractors so that the noise levels of the used equipments remained at manufacturers’ specifications. Workmen were also reminded constantly to use proper gears so that the occupational health and safety norms were not violated. However, many of the above inconveniences were largely absent where trenchless pipe laying technique has been adopted.
Refurbishment of STP 54. A safety audit by competent authority has been planned so that all safety related issues are addressed during the operation of the STPs. Canal Excavation work
55. Environmental problems related to stability of canal banks to be excavated were faced at few sites. Details of such problems with the adopted remedial measures taken expeditiously to mitigate the adverse situations to a large extent are discussed in the following paragraphs:
56. Possibility of soil erosion and landslide due to bank instability arose along a few vulnerable stretches of many canals during excavation posing dangers to stability of excavated canal banks and in some cases close by hutments/buildings and roads. Extensive Eucalyptus ballah piling to prevent bank collapse and soil erosion along vulnerable stretches of the canals under excavation were taken up expeditiously. In cases where the design requirement is for permanent protection of canal sections, concrete lining has been provided (Table 6).

As per design a length of 43 m of Keorapukur canal was to be re sectioned with RCC trough and the balance length of the canal would have lined and unlined sections. After commencement of work, from safety consideration of the canal banks and adjoining canal bank road arising out of initial encountered soil condition, the design was revised with provision of RCC trough for the entire 1063 m of the canal under re sectioning. It was also planned that there would be continuous timber piling on both sides of the trough section during excavation. However, during early stages of construction with the above design, the timber shoring failed beyond chainage 170.0 m threatening the very stability of the adjoining canal bank road. 58. To mitigate the adverse situation during excavation of Keorapukur canal as mentioned above, steel shoring beyond the founding level is being put in place in locations given in Table 7. The steel shorings will be removed in due course after construction of U trough and retaining wall are completed.

VIII. RECOMMENDATIONS FOR IMPROVEMENT/ REVISION OF THE MITIGATION MEASURES AND/ OR IMPLEMENTATION OF THE EMP IF ANY
59. At this stage of implementation of the EMP of the KEIP, no improvements/revisions of the mitigation measures of the EMP are suggested/ recommended. The provisions are adequate
24 to meet the environmental safeguards and efforts are being made by the Project to implement those provisions fully. 60. However, extra efforts will be made to ensure the following during implementation of the EMP in the remaining period of KEIP: • management of the work sites particularly with respect to proper temporary storage/stacking of construction materials, of excess soil before their reuse within the site or transportation to off site locations so that the sites look clean and better organised, • isolation of the work sites by appropriate barricades or temporary fencing, wherever ground situation permitted, promoting better safety in the vulnerable places, • compliance to occupational health and safety provisions through compulsory use at construction sites of hard hats, gum boots, hand gloves, protective goggles, safety belts, face masks and ear muffs, as are necessary, both by the construction workers and visiting supervisors • disclosure of information on the work programs through prominent display of bill boards at all work sites giving essential information about the corresponding work programs • informal public consultations and discussion with stake holders whenever felt necessary 61. In addition Project is actively considering safety auditing inclusive of fire hazards and disaster management of the STPs and Pumping Stations and implementation of the audit recommendations for safe operation of the facilities
