National Highways comprise about 2% of total road length in the country and carry over 40% of total traffic across the length and breadth of the country. National Highways Authority of India (NHAI) constituted under the National Highways Authorities of India Act, is responsible for the development, maintenance and management of National Highways in the country. One of the major tasks mandated to NHAI is the implementation of National Highways Development Project (NHDP) comprising of Golden Quadnlateral, North -South and East-West corridors. The golden quadrilateral (GQ) comprises of the following stretches Stretch Length (Km) Delhi - Calcutta 1469 Calcutta - Chennai 1751 Chennai - Mumbai 1278 Mumbai - Delhi 1454 (GQ) Total 5952 The contract packages and status of implementation under Delhi - Calcutta stretch is presented in the Table 1.1: Table 1.1: Contract Packages of NH-2 and Status of Implementation Stretch Length Distance Funding Status/Agency (Km) From Delhi (Km) Delhi - Mathura 145 145 ADB 4 LANED Mathura - Agra 54 199 OECF 4LANED Agra - Sikandara Contract I B (-Makhanpur - Etawah i e Km 250 5 57 306 WB - IV Award after 3/2001 - Km 307 5) Agra - Sikandara (Etawah Bypass i e.

It is a part of consultancy Package III, which has a total length of 202 km, starting from Khaga (Km 115) and ending at Varanasi (Krm 317).This package has been divided into five construction packages as described below: In association wlth anW "44~ Consolidated Environmental Management Plan tor ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 Packages Section (Krn) Length (Kin) Package III A Khaga - Kokhraj 43 (Km 115- 158) Package III B (i) ABP-1 Gang Bridge Allahabad Bypass (Km 163.267-164.280) 1.013 (84.708 Km) (ii) ABP-2 (Kml58-163.267 and Km 164.280-198.000) 38.987 (hi) ABP-3 (Km 198.000 -Km 242.708) 44.708 Package III C Handia - Varanasi 72 (Km 245.000 - Km 137) The map showing Allahabad bypass has been given in Figure 1.1 It may be noted that four lanning is under progress in Khaga- Kokhraj and Handia- Varanasi construction packages. 1.2 Need of By-pass for Allahabad Town Over a period of time traffic volume has increased many fold on National Highway -2 due to increased traffic on NH-2 and merging of four other major roads, viz. NH-27 (connecting Rewa),SH-7(connecting Jaunpur), SH-9 (connecting Lucknow) and SH-47 (connecting Mirzapur) into Allahabad town . Current Situation As per the latest traffic census, the traffic volume on NH-2 on either side of Ahahabad town is of the order of 8000-10000 PCUs whereas intensity of traffic within the city is of the order of 25000-28000 PCUs of fast moving vehicles. This gives a fair idea of the extent of mixed traffic passing through Allahabad town. Due to the increased traffic and restricted width of carriage way operative speed in Allahabad town is of the order of 10 kmph on NH-2. Needs Assessment In order to achieve higher operative speed for traffic in future years the following options were explored. - Widening the existing NH-2 in city portion to four lanes; - Construction of elevated structure in town above existing NH-2 carriageway; and - Construction of Bypass. The widening of National Highway - 2 in the town portion was not feasible due to the following reasons. 1. It could have resulted in massive destruction of properties displacement of large no of people and resulting R&R problems. In association with AP44 Consolidated Environmental Management Plan for ABP-I (Ganga Bridge) of Allahabad Bypass of NH-2 2. The construction of elevated structure was rejected due to financial and environmental considerations. The construction of elevated structure would have also reduced sun light to the households on either side of NH-2. Therefore bypass to the city was found to be the most viable option. The present alignment of bypass was adopted for detailed DPR after careful evaluation of various alternative alignments. The details on "Selection of present alignment are covered in the following section. 1.3 Selection of Present lignment (Analysis of Alternativel Seven alternatives alignments were considered for the bypass of NH 2 for the Allahabad town. Among these seven alternative alignments only one alignment (AS1) was on southern side, five (AN1 through AN5), were on the northern side of Allahabad Town and the seventh alternative is 14.5 km long elevated structure with four lane above the existing National Highway within Allahabad town. During the feasibility phase of the project, a separate study was undertaken for finalization of the alignment and a separate report named as "Selection of Alternatives" was prepared. For the selection of best alternative the relative merits of various alternatives were assessed by a weighted marking scheme. The weights were allotted to vartous factors which could influence the choice i.e., capital cost, scope of future widening, land acquisition, user cost, impact on environment and suitability of alignment etc. For each of these factors the vartous alternatives were marked on a scale of 1 to 5. The marks were multiplied by various weights. The sum of weighted marks provided an objective ranking of various alternatives. Numerical values to various factors were assigned by consensus with experts in different fields and NHAI officials. The marks in two categories namely capital cost and land acquisition were calculated numerically, but other categories were arrived subjectively after discussion with various experts. Based on described evaluation, alternative 'AN-4' was found to be the most viable option. The detailed report of AN-4 has been submitted to the World Bank and this report has been accepted. Therefore EIA of AN -4 was carried out by the DPR consultants. 1A DPR Consultants The detailed project report has been prepared by a Consortium consisting of SNC Lavalin International and Gherzi Eastern Ltd for bypass construction packages ABP-2 and ABP- 3. M/s Tandon Consultants (P) Ltd. were associate consultants for Ganga Bridge package, ABP-1. The environmental and social assessment for the project has been carried out by M/s Gherzi Eastern Ltd, Kolkata. The consultants had first undertaken environmental screening exercise to identify critical environmental issues of the project followed by environmental impact assessment. The EIA preparation led to identification of potential environmental hotspots and their feasible remedial measures (including avoidance, mitigation and enhancements) which were made a part of environmental management plan. In association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of 4 Allahabad Bypass of NH-2 1.5 Independent Environmental Reviewers IIERJ Since the project has been categorized as category 'A' project due to its cumulative magnitude of social and environmental impacts, independent reviewers have been appointed to review the EIA process as per operational directives of World Bank. The independent reviewers is a consortium consisting of DHV Consultants and MDP consultants (P) Ltd.; New Delhi. The Independent Review Consultants have reviewed and strengthened the EIA report prepared by DPR consultants and accordingly revised the EMP. Approach & Methodology adopted The scope of the present EMP includes review and strengthening of the earlier EMP by adopting the following approach. 1. Gap Analysis 2. Addressal of the gaps through Data verification Physical verification through sample site visits Collection and interpretation of required data 3. Summarizing the EMP during construction and operation stage 4. Identification of monitoring requirements Initially gaps identification was carried out based on the report submitted by the consultants. Subsequently, the site visit was undertaken to verify the identified gaps. This was followed by the detailed discussion with the consultants, NHAI and other government agencies. The implementation of EMP including reporting requirements for the ongoing project by NHAI on Khaga Kokhraj section was also studied as a sample during the site visit. Documents such as detailed project report (DPR), strip plans and other drawings were studied and checked for incorporation into environmental consideration of the project. 1.6 Deliverable This report summarizes the EMP for the Ganga bridge from km 163.267 to km 164.280 (1.03 km). The following chapters describe the project, identified impacts, mitigation measures and monitoring, reporting requirement, bills of quantities and budget required to implement EMP. The appendix also describes a section on best practices to be followed during construction of the bridge. In associatien with Consolidated Environmental Management Plan for ABP-I (Ganga Bridge) of Allahabad Bypass of NH-2 I2)PROJECT DESCRIPTION 2.1 PROJECT DESCRIPTION The total length of Allahabad bypass is 84.725 km and is divided into three construction packages. It has been designed as an access controlled toll road with divided 4-lane carriageway with provision of 6 - laning to cater to future traffic projections. The design life of the project is 30 years. A 70 m Right of Way (RoW) has been proposed for the project corridor with provisions of high embankments, interchanges, toll plaza, rest area, etc. and 90 m RoW at appropriate places. The three construction packages are as stated below: ABP - 1: Ganga bridge with river training work from km 163.267 to km 164.280 (1.03 kmn) ABP- 2: From km 158.000 to km 163.267 and km 164.280 to km 198.0 (38.987 km) ABP - 3: From km 198.0 to km 242.708 (44.708km) 2.1.1 Proposed Bypass Carrlageway Details Highway design Is based as per relevant IRC standards and international codes of practice. The bypass will have access control with provision of parallel service roads. No access will be allowed to slow moving vehicles on the main carriageway except at interchanges, toll plazas. Specifications of RoW, carriageway, service road, shoulders, median, etc. are given below: 1.

The terrain is flat and agriculture land and settlements about the RoW. The culverts will be extended in the widening. The widening of these existing NH-2 portions to four lanning is planned as a part of bypass. In order to accommodate the widening land acquisition will be there. Major interchanges are planned at start point (km 160) and end point of new RoW (km 242.0) to segregate the through traffic from local traffic. There are three culverts in the portion between km 158 to 160 and two culverts in km 244 to 245 Alignment of Bypass on New ROW The bypass takes off NH-2 alignment at km.160 and traverses in an east direction about 2 km along the existing NH 2 then turns north-east through the cultivated land. It crosses Ganga River at Km. 163, and continues in the same direction upto km 167, crossing Doab In as2- 2 s4Ar9z In association With X, Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of 5 X X Allahabad Bypass of NH-2 River (Km 166.362). From there it heads eastward crossings SH 38 at (Km. 185.544) and Lucknow - Allahabad Rail link at Km 188.749. From there it continues in north-east direction and crosses SH 9 at Km. 196.600 and heads towards east to cross Pratapgarh-Allahabad Rail link at Km. 199.810. The alignment now takes south-east direction crossing SH7 at Km. 216.816 and turns south ward at Km. 230 to meet NH-2 at Km. 242.10 and ends at km. 245 of existing NH-2. The area through which the new alignment of bypass passes is predominantly agricultural land. As the bypass alignment passes through agriculture land there will be minimum impact on human settlements. This agriculture land falls under irrigated category, due to canal network, catering to four crops a year. 2.2 Salient Features of Bypass Alignment District Boundary Kaushambi, Pratapgarh and Allahabad Village passing though :110 Villages House holds getting affected . 97 Structures getting affected 267 Trees to be cut 3298 (Prnvate trees on new alignment and trees on existing NH 2 section) SH - Crossing : 3 (SH-38, SH-7 and SH-9) Major Rivers : 3 (Ganga, Doab and Mansaita) Canals : 32 Drain, Nullahs and Stream : 29 Total Land to be acquired : 781 Ha (687 ha private and 94 ha Govt. land Approx.)

The broad indicators defining the environmental setting of the study area are given below. 1. Air Quality (i.e. NOx, SO2 and RPM) along the bypass alignment is within permissible limit prescribed by CPCB except SPM, which exceeding in few places. The predicted air quality based on modeling and baseline studies indicates levels are also within CPCB liimts. 2. The surface water flow in the project area is in the direction of the Ganga River. Therefore, all other existing river and streams flow from north of Ganga flow towards south and east while those are present south of the Ganga flow north and east. 3. In general the ground water table of the study area varies between 10-15m. The water table also varies in different seasons. 4. The topography of the area is plain. 5. The entire length of Allahabad bypass falls in Zone III with a seismic coefficient of 0.02. Hence the area is relatively stable. 6. The soils in the area are of alluvial type, capable of producing high yields, largely due to the rich soil nutrients deposited by the Ganga and its tributaries. 7. The predicted noise levels based on baseline surveys and modeling indicate that predicted noise levels for day time are well within CPCB limits considering the traffic projection till 2026. Night time noise levels exceed CPCB limits for the horizon year 2026 and 2036. Though no change in the macro-climatic setting (precipitation, temperature and wind) is envisaged due to the project, the microclimatic parameters are likely to be temporarily changed mainly by vegetation removal and laying of pavement surface.

Air Pollution: Stock-piles > Mist sprays should be provided at appropriate places for preventing dust pollution during handling and stockpiling of stones and loose earth. > Over Burden (OB) waste dumps shall be sprayed with water as they are the major source of air bome particulate matter/dust. O GB waste dumps shall be reclaimed/ afforested to bind the loose soil and to prevent soil erosion. Haulage > Regular water spraying on haulage roads during transportation of construction material by water sprinklers. > Transfer points for transporting construction material shall be provided with appropriate hoods/chutes to prevent dust emissions. > Dumping of construction material should be from an optimum height (preferably not too high) so as to reduce the dust blow. Occupational Noise Pollution Control To keep the ambient noise levels within the permissible limits, the measures to be adopted are: > Innovative approaches of using improvised machinery designs, with in-built mechanism to reduce sound emissions like improved silencers, mufflers and closed noise generating parts. > Procurement of drill, loaders and dumpers and other equipment with noise proof system in operator's cabin. > Confining the equipment with heavy noise emissions in sound proof cabins, so that noise is not transmitted to other areas. > Regular and proper maintenance of noise generating machinery including the transport vehicles to maintain the noise levels. > Provision should be made for noise absorbing pads at foundations of vibrating equipment to reduce noise emissions. 3.3 Disaster Management Plan Emergencies may occur due to vanous reasons, like natural calamities i.e floods, construction/ operation related activity and spills due to accidents. The disaster management plan is aimed at insuring the safety of the people, protecting the environment and equipment and property safety. This plan summarizes identification of hazards, response and recommendations to mitigate and minimize environmental emergencies. During construction stage, it is proposed that the environmental coordinator act as emergency coordinator in case of emergency. He should be having the following resources at his disposal at the time of emergency. 3 - 12 In association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Ailahabad Bypass of NH-2 1. Communication system 2. Vehicles 3. MSDS 4. Trained manpower 5. Procedures for meeting emergency Response System should address the following features/ issues > All residents and employees need to be informed using the PA system to stay indoors and not to use any roads crossing, which may get affected. > The ambulance and fire tender need to be informed to be ready > Emergency response team should be put on alert and district authorities to be notified if any search and rescue operations need to be carried out. > Once the water body is restored to its normal flow conditions then an overall assessment of the damage caused due to the breach on people and property needs to be carried out. > All debris in the area needs to be cleared once the rescue operations have been carried out Response due to fuel Leakage > The affected area should be evacuated and cordoned off immediately > Only trained and experienced emergency response team members approach the area > Inform electrical department to shut down power supply > Ensure that only concemed personnel are present in the affected area and all other personnel and guests are moved to the nearest assembly points. > Source of leakage to be traced and isolated from all the other areas. In case of a fire follow the instructions in case of fire. Response in case of Fire > On sighting a fire the first person should immediately inform the nearest resource center/ and the exact location and type of fire in detail. > If the fire is small engage in extinguishing the fire using the nearest fire extinguisher. > Move the staff to the emergency assembly point. > The control room will immediately inform the first aid Center and the quick response team which consists of trained fire fighting personnel. > Mobilize the fire tender. > The Quick Response team will immediately move to the point of fire and take all necessary steps to stop the fire.

O They must conduct a study of accident history based on accident records maintained by the police, along these stretches to see any patterns of frequently occurring accidents at certain accident points. NHAI should take measures to reduce such accidents by adopting one or more of the following actions - assess the condition of the road at/near the point to assess the cause of accidents. O Take adequate measures to address accidents, install warming signs for speed check/no overtaking etc. o Information boards giving contact details of hospital, ambulance, fire brigade, police and other facilities should be erected along the highway at appropriate distances. L At an appropriate distance from population pockets along the highway, boards, warming drivers of crossing pedestrians and live stock should be erected. L Boards should also be erected before population pockets giving contact details of emergency facilities in the population pockets. O NHAI must ensure that land close to the highway are not allowed to be unduly populated by commercial activity but land allocation preference should be given to service establishments like tire repair shops, mechanics, public call offices (PCO), rest rooms, spare parts shops etc. O They must ensure that warning sign boards are erected at all dangerous curves, embankments, bridges, road repairs works, crossings and other such places thait increase accident probability. 3A Monitoring Program The monitoring program is an important element of EMP to test the efficacy of Impact assessment and mitigation measures and to achieve the desired environmental quality both during construction and operation phase of the project. The broad objective of the monitoring program is as follows. 1. Monitoring to meet the compliance 2. Effects monitoring The purpose of the monitoring program is to ensure that the envisaged objectives of the project are achieved. To ensure the effective implementation of the EMP, it is essential that an effective monitoring program be designed and carried out. The broad objectives are * To evaluate the performance of mitigation measures proposed in the EMP * To evaluate the adequacy of Environmental Impact Assessment * To suggest improvements in management plan, if required * To enhance environmental quality * To satisfy the legal and community obligations. The monitoring program lays the basic framework for quantitative evaluation of impacts. This evaluation is based on monitoring of performance evaluation indicators. 3A.1 Performance Indicators (Pis) The physical, biological and social components of particular significance, identified in affecting the environment at critical locations, have been recommended as Performance Indicators (PIs), and are listed below. * Air quality * Water quality * Noise levels around sensitive locations. 411-07000yo, I/ V In association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 * Replantation success / survival rate * Soil contamnnation * Erosion indices * Restoration of borrow pits * Sedimentation rate downstream of bridges, culverts * Vital statistics on health * Accident frequency The environmental parameters that may be qualitatively and quantitatively measured and compared over a period of time have been selected as Performance Indicators (PIs). * Air Quality * Noise levels * Water Quality . Flora * Soil Contamination Following sub-sections describe each of these Pls in detail. Ambient Air Quality (AAQ) Monitoring Ambient air quality parameters recommended for monitoring road transportation developments are as follows: Respirable Particulate Matter (RPM) Suspended Particulate Matter (SPM) Carbon Monoxide (CO) Oxides of Nitrogen (NOx) Hydro-Carbons (HC) Sulphur Dioxide (SO2) Lead (Pb). These indicators will be monitored at designated locations starting from the commencement of construction activity.

These standards have been described in table 3.4. Sound pressure levels would be monitored on twenty-four hour basis. Noise should be recorded at a "A" weighted frequency using a " slow time response mode" of the measuring instrument. The location, duration and the noise pollution parameters will be monitored and the responsible institutional arrangements are detailed out in the following sections. 3 -18 in association With Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Eui Allahabad Bypass of NH-2 Table 3.4: Noise Level Standards (CPCB) Zone Noise level for Day Noise level for Time Leq dB(A) Night Time dB(A) Industrial area 75 70 Commercial area 65 55 Residential area 55 45 Silence zone 50 40 Residential 65 50 Commercial 70 Day time - 6 00 am - 9 00 pin (15 hours) Night time - 9.00 pm - 6 00 am (9 hours) Soil Contamination Contamination of the soil, especially due to increased levels of Pb, Cd and Cr are likely due to the increased traffic movement on the project corridor. The comparison of the concentrations of these parameters before and after the project will aid in arriving at the increase in concentrations of these heavy metals, if any.

Monitoring involves periodic checking to ascertain weather activities are going according to the plans. It provides the necessary feedback for project management to keep the program on schedule. The rationale for a reporting system is based on accountability to ensure that the measures proposed as part of the Environmental Management Plan get implemented in the project. Therefore there is a need for evaluation of institutional capacity of the stakeholders including the organization structure and reporting structure. This chapter summarizes the existing institutional structure, proposed reporting structure and training needs for NHAI for implementing EMP. 42 ExIsting Institutional Arrangements The existing organization structure of NHAI and other stakeholders is summarized in the following section. NHAI has an organization structure at the corporate and project level. The reporting structure between the two levels is shown in the following figure. Corporate Level The NHAI, through the member (WB) will be responsible for the effective implementation of the project activities. The member is assisted by a General Manager (WB) and the Project Directors of the various project packages, Separate NHAI units, Project Implementation Unit (PIU') with a Project Director as its head have been established for each of these packages. International consultants have been appointed for carrying out the feasibility study and preparation of the Detailed Project Reports and designs for four-laning, of the project packages. Prolect ImPlementatlon Units These are separate NHAI units established at the project locations for each of the project packages, with a Project Director (PD) as its head. The Project Director is assisted on all technical issues related to environment and R&R by a manager. The various Project Directors, in turn report to the General Manager (WB), who is responsible for the co-ordination of the project preparation activities of the various project packages. in assocation wi-tn ,*, Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 Figure 4.1 Structure of PIU Unit General Manager (WB) Environmental and Social Development Unit (ESDU) Project Di,reor p Corporate Office GM (Environment) III Manager (1) Manager (3) l (Technical) (R&R) with work add. of Environmental Office Of f t ~~~~Supervision . . ~~~~Consultant Enivironmental Officer of Ctonfr:lctor The review of the preparation of the Environmental and Social assessments for the project and ensuring effective implementation of the Environmental Management Plan/ Resettlement Action Plan will be carried out by the GM (Environment) at Corporate office in due consultation with the manager (environment) and manager (R&R) at PIU. Environmental Unit at the NHAI Corporate NHAI, primarily betng a road agency, till recent past did not have the capacity to address the environmental/social issues likely to result because of the project. To assess, advise and monitor the environmental performance of the various projects being planned, designed and implemented by the NHAI, an Environmental and social development (ESDU) has been established at the Corporate Office of the NHAI. The Environmental Unit is headed by the General Manager (Environment), and is assisted by ONE Deputy General Manager (DGM) and one manager. The Environmental Unit is responsible for the co-ordination of the environmental and social issues of the various project packages and shall work in close interaction with the environmental managers at the various PlUs. In association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 4.3 Other Stakeholders The other stakeholders, which assist NHAI include DPR consultants, independent reviewers, supervision consultants, NGO's and contractors. DPR Consultants The DPR Consultants assist the PIU during project preparation. The Environmental and Social experts of the DPR consultants have been responsible for the preparation of EA as per the ToR approved by the World Bank. The major inputs of the DPR consultants ends with submission of draft documents. However, their technical inputs continue for the entire project duration on a limited scale. Independent Reviewers Since Allahabad bypass project has been categorised category 'A' project due to cumulative environmental and social impacts, therefore, independent reviewers have been appointed. The reviewers reviewed the environmental and social assessments carried out by the DPR consultants and have identified missing gaps These missing gaps have been rectified and consolidated environmental and social assessment have been submitted to the World Bank and NHAI along with Independent Review report. Supervision Consultants (SC) The project envisages the use of Supervision Consultants for the implementation stage to assist the PIU during construction stage. The SC will assume the role of the Engineer and will have the powers and responsibility for the approval of bills, etc. normally vested with the client. These consultants will be selected through International Competitive Bidding (ICB) and it is expected that they will have substantial capability to supervise the implementation of the environmental component of the project as part of their assignment. Implicitly, the construction supervision consultants are expected to have specialists to advice and co-ordinate implementation of the measures developed as part of the Environmental Management Plans for various construction packages of the Allahabad bypass. Non-Governmental Organisations The provisions envisaged in the RAP shall be implemented by Non-Governmental Organisations contracted for the purpose by the PIU. Their mandate is to monitor the progress and implementation of the proposed measures. A representative of the NGO will also be a part of the District Level Committee which will decide the replacement value of land and properties to be acquired. One representative of the NGO will also be a part of the Grievance Redressal Committee for each district. Contractors The execution of the works will be responsibility of the contractor. Three contractors will be appointed by International Competitive Bids (ICB) for the three packages of this project. It is expected that the environmental measures will also be implemented by the same contractors who will execute the road and bridge work It will be ensured that each contractor will have enough environmental/social expertise to incorporate In association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 environmentally-sensitised construction practices. Though each contractor will have a set- up for executing works specified in the EMP, it is expected that staff will be appointed to implement EMP for the successful completion of the works entrusted. 44 Institutonal Needs Assessment Need for further Strengthening of NHAI - ESDU at Corporate Office There is a need to strengthen the ESDU unit by inducting manpower as many projects are going simultaneously. Additional social and environmental managers need to be inducted to assist GM environment. This induction should be according to HR pollcy of NHAI. Need for additional capacity During the implementation stage, construction will proceed simultaneously on the 3 sub packages of Package III. It has been estimated that the present resources of the PIU will be extremely stretched due to overlap of construction activities. It is therefore recommended that a separate environmental manager be inducted at PIU level since manager technical looking after environmental aspects will find it difficult to cope up with the implementation work of the project. 4.5 Proposed Set-up The proposed set up for project envisages to cover the following aspects. * Strengthening the environmental component of the PIU and ESDU * Associate the other stakeholders in the existing team in order to implement the provisions of the Environmental Management Plan * Integrated approach to implement EMP &-RAP * Monitor & upgrade EMP Institutional Setting for the Project Important issues and recommendations relevant to their identified role & responsibilities in the project implementation is presented in the following sections. Prolect Implementation Unit * Strengthening of NHAI's PIU environment team by recruiting at least one environmental manager responsible for looking after environment issues. * PIR needs to identify laboratories approved by UP Pollution Control Board and develop a database of laboratories to carryout onsite monitoring formulated in EMP. * The contractor and supervision consultants should be informed of this database so that they can procure services of only empanelled laboratories for monitoring. In association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 * PIU need to be adequately equipped with instrumentation and should have trained manpower to address environmental emergencies. * There is a need to develop an organized reporting system in association with headquarters.

In association with l Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 It is expected that the CS will employ a full time Environmental specialist. A sample of duties and qualifications for such a specialist are given below in Box 4-1. Contractors The Contractors are the major implementing agencies of EMP. The contractors are recommended to employ Environmental Engineer/s. The roles and responsibilities of these engineers are given below. * Ensure proper construction and maintenance of the facilities for the labour camps * Measurement and verification of quantities for environmental enhancement * Ensuring that proper environmental safeguards are being maintained at borrow sites and quarries * Prepare the bills of quantities for the work carried out for enhancement * Ensure that proper facilities are available for the monitoring of ambient air quality and collection of water and soil samples as mentioned in the environmental monitoring plan * Ensure analysis and reporting of reporting of monitoring results OtherAgencies The other agencies involved in project activities include the NGO procured for the implementation of the RAP. Box 4-1: Draft Terms of Reference for Supervision Consultants' Environmental Specialist The Allahabad Bypass Road Project, financed by the World Bank, integrates environmental and social Issues in the planning and design of the Htghway. An Environmental Management Plan (EMP) has been prepared for each construction package and is Integrated in the technical specification and contract documents. The prime duty of the Environmental Specialist is to supervise the implementation of the EMP by the Contractors and to ensure that the day-to-day construction activities are carried out in an environmentally sound and sustainable basis. The scope includes development of environmental procedures and good construction practices, development and delivery of training programs, etc. Qualifications and Experience . A civil engineer preferably with postgraduate specialization in environmental engineering. . 12 years of working experience related to the integration of environmental and social issues in the design, construction and operation of transport projects. Experience in construction management and operational maintenance of highways is preferred. Principal Duties . Supervise the implementation of the EMP by the Contractors. . Hold regular consultation meetings with the environmental managrat PIU . Review the Contractors' Environmental Implementation Plans to ensure compliance with the Environmental Management Plan (EMP). . Organise periodic environmental training programmes and workshops for the staff of the Contractors, Construction Supervision Consultants and the Project Implementation Units (PIU). . Develop good practices construction guidelines to assist the contractors in implementing the EMP. . Monitor tree plantation programmes and the periodic environmental monitoring (air, noise, water, etc.) programmes to ensure compliance with the Statutory requirements and the EMP. . Prepare and submit regular environmental monitoring and implementation progress reports. ^fl//w in assoclialhn with < W Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 Enuironmental Reportng System lERSI Environmental monitoring involves periodic checking to ascertain whether environmental activities are going according to the EMP. It provides the necessary feedback for project management to keep the program on schedule. The evaluation is essentially a summing up of the project assessment of whether those activities have actually achieved their outcomes. The important features of ERS are summarized below. * The reporting system will operate linearly with the contractor who is at the lowest rung of the implementation system. The contractor will report to the Supervision Consultant, who in turn shall report to the PIU and Environmental and Social Development unit of NHAI at corporate office. * All reporting by the contractor and Supervision Consultant shall be on a quarterly basis. * The ESDU in association with PIU shall be responsible for preparing targets for each of the identified EMP activities. * All subsequent reporting by the contractor shall be monitored as per the targets set by them before the contractors move on to the site. * The compliance monitoring and the progress reports on environmental components may be clubbed together and submitted to the ESDU at corporate office and PIU, quarterly during the implementation period. * The operation stage monitoring reports may be annual or biannual, provided the Project Environmental Completion Report shows that the implementation was satisfactory. * 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. This would help in rationalising the implementation of the EMP during the remaining duration of implementation. Solutions for further effective implementation should also come out as a result of the compliance monitoring reports. * Responsibilities for overseeing will rest with the Supervision Consultant's staff reporting to the PIU and ESDU corporate office. * Capacity to quantitatively monitor relevant ecological parameters would be an advantage but monitoring will primarily involve ensuring that actions taken are in accordance with contract and specification clauses, and specified mitigation measures as per the EMP. * Photographic records will also be established to provide useful environmental monitoring tools. in association with Consolidated Environmental Management Plan for ABP-l (Ganga Bridge) of t) AJlahabad Bypass of NH-2 * 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. The reporting system has been prepared for each of the stage of road construction namely: - Pre construction stage - Construction Stage - Operation Stage This reporting shall be done through: - Reporting by the Contractor to the SC - Reporting by SC to PIU/ EDSU The stage-wise reporting system is detailed out in the following Table 4.1.

The formats for the reporting of the various environmental issues through the various stages of the project implementation are annexed to the individual EMPs. Internalizing Environmental Exuertise In the NHAI It is expected that NHAI will develop internal capability over the next decade in the highways sector in India, which needs to be fully internalsed. It is important that there should be substantial environmental capacity beyond the staff, directly responsible for implementing the EMP in different projects. This may be achieved through training and dissemination of information. 7400 In association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 4. Operationalisation Operationalization of the environmental setup for this project would involve the following aspects. These are: - Identification and appointment of Staff - Procurement of NGOs, supervision consultants, contractors and other agencies responsible for implementation Each of these aspects is described below. Identification and Appointment of Staff At the project level, the PIU has already been functional. Three managers (engineers) are already working for the project's environmental and social components. An additional managerial staff will be inducted when implementation begins. It would be advantageous if this manager has post-graduate qualifications in Environmental Engineering or previous experience on environmental related activities of road projects. Procurement of NGOs and other Agencies NHAI will appoint the NGO's to implement the RAP provisions. NHAI will procure the services of any other agency, such as educational institutions for monitoring, if found essential, during the implementation stage. Supervision Consultants (SC) The NHAI will appoint supervision consultant selected through International Competitive Bid (ICB) Contractors Three separate contractors need to be appointed for the three sub construction packages. These contractors will be appointed through international competitive bids. Training The ESDU at the NHAI headquarters and the PIU, responsible for the implementation of EMP, need to be trained on the effective implementation of the environmental issues. To ensure the success of the proposed implementation set up, there is a need for training and skill upgradation. As part of the TNHP and GTRIP project different training program have been worked out by NHAI to incorporate the project as well as the intermediate - term capacity building needs of the NHAI. Looking into the potential requirements of each of the target groups, following training modules are suggested as part of ABP. > Module 1: Environment Overview in association with Consolidated Environmental Management Plan for ABP-1 (Ganga Bridge) of Allahabad Bypass of NH-2 > Module 2: Environmental Regulations and Acts > Module 3: Pollution > Module 4: Environmental Impact Assessment > Module 5: Environmental Management Plan )' Module 6: Highways Projects and Environmental Issues > Module 7: Environmental Issues in the Project > Module 8: The Environmental Management Plan for Highway Project > Module 9: Environmentally Sound Construction Management ) Module 10: Planning for Environmentally Sustainable Operation of Highways > Module 11: Long Term Environmental Issues in Highway Management ADDITIONAL TRAINING A training program under ABP has been formulated taking into account the existing training program imparted under TNHP and the budgetary allocations. The training is focused on the environmental issues related with road construction and both theoretical and practical aspects are covered in it.
