"fl INTRODUCTION

1.1 Background of the Prolect

India has embarked on a 10-year highway transportation improvement program as a partof the national policy to globalize its economy. National Highways comprise about 2% oftotal road length in the country and carry over 40% of total traffic across the length andbreadth of the country. National Highways Authority of India (NHAI) constituted underthe National Highways Authorities of India Act, is responsible for the development,maintenance and management of National Highways in the country. One of the majortasks mandated to NHAI is the implementation of National Highways DevelopmentProject (NHDP) comprising of Golden Quadnlateral, North -South and East-Westcorridors. 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 ispresented in the Table 1.1:

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 -2due 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 Ahahabadtown is of the order of 8000-10000 PCUs whereas intensity of traffic within the city is ofthe order of 25000-28000 PCUs of fast moving vehicles. This gives a fair idea of theextent of mixed traffic passing through Allahabad town. Due to the increased traffic andrestricted width of carriage way operative speed in Allahabad town is of the order of 10kmph on NH-2.

Needs Assessment

In order to achieve higher operative speed for traffic in future years the following optionswere 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 thefollowing reasons.

1. It could have resulted in massive destruction of properties displacement oflarge no of people and resulting R&R problems.

In association withAP44


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.

1.5 Independent Environmental Reviewers IIERJ

Since the project has been categorized as category 'A' project due to its cumulativemagnitude of social and environmental impacts, independent reviewers have beenappointed to review the EIA process as per operational directives of World Bank. Theindependent reviewers is a consortium consisting of DHV Consultants and MDPconsultants (P) Ltd.; New Delhi. The Independent Review Consultants have reviewed andstrengthened the EIA report prepared by DPR consultants and accordingly revised theEMP.

Approach & Methodology adopted

The scope of the present EMP includes review and strengthening of the earlier EMP byadopting the following approach.

1. Gap Analysis

2. Addressal of the gaps through

Data verificationPhysical verification through sample site visitsCollection 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 theconsultants. Subsequently, the site visit was undertaken to verify the identified gaps. Thiswas followed by the detailed discussion with the consultants, NHAI and othergovernment agencies. The implementation of EMP including reporting requirements forthe ongoing project by NHAI on Khaga Kokhraj section was also studied as a sampleduring the site visit. Documents such as detailed project report (DPR), strip plans andother drawings were studied and checked for incorporation into environmentalconsideration 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, mitigationmeasures and monitoring, reporting requirement, bills of quantities and budget required toimplement EMP. The appendix also describes a section on best practices to be followedduring construction of the bridge.

I2)PROJECT DESCRIPTION

2.1 PROJECT DESCRIPTION

The total length of Allahabad bypass is 84.725 km and is divided into three constructionpackages. It has been designed as an access controlled toll road with divided 4-lanecarriageway with provision of 6 - laning to cater to future traffic projections. The designlife of the project is 30 years. A 70 m Right of Way (RoW) has been proposed for theproject 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 km164.280 (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 ofpractice. The bypass will have access control with provision of parallel service roads. Noaccess will be allowed to slow moving vehicles on the main carriageway except atinterchanges, toll plazas. Specifications of RoW, carriageway, service road, shoulders,median, etc. are given below:

2.1.2 Descriptlon of Area and Terrain

Alignment along NH-2 on Existing ROW

The existing NH-2 from km 158 to 160 and km. 244 to 245 form part of this bypasspackage. The terrain is flat and agriculture land and settlements about the RoW. Theculverts will be extended in the widening. The widening of these existing NH-2 portionsto four lanning is planned as a part of bypass. In order to accommodate the widening landacquisition will be there. Major interchanges are planned at start point (km 160) and endpoint of new RoW (km 242.0) to segregate the through traffic from local traffic. There arethree 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 2km along the existing NH 2 then turns north-east through the cultivated land. It crossesGanga River at Km. 163, and continues in the same direction upto km 167, crossing Doab

River (Km 166.362). From there it heads eastward crossings SH 38 at (Km. 185.544) andLucknow - Allahabad Rail link at Km 188.749.

From there it continues in north-east direction and crosses SH 9 at Km. 196.600 andheads towards east to cross Pratapgarh-Allahabad Rail link at Km. 199.810. Thealignment now takes south-east direction crossing SH7 at Km. 216.816 and turns southward 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 agriculturalland. As the bypass alignment passes through agriculture land there will be minimumimpact on human settlements. This agriculture land falls under irrigated category, due tocanal network, catering to four crops a year.

Environmental Setting

3.1 Environmental Setting

The entire area of Allahabad bypass lies in a sub-tropical region with marked monsoon effects. The broadindicators 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 limitprescribed by CPCB except SPM, which exceeding in few places. The predicted air quality basedon 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, allother existing river and streams flow from north of Ganga flow towards south and east whilethose 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 alsovaries 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. Hencethe area is relatively stable.

6. The soils in the area are of alluvial type, capable of producing high yields, largely due to the richsoil nutrients deposited by the Ganga and its tributaries.

7. The predicted noise levels based on baseline surveys and modeling indicate that predicted noiselevels for day time are well within CPCB limits considering the traffic projection till 2026. Nighttime 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 tothe project, the microclimatic parameters are likely to be temporarily changed mainly by vegetationremoval and laying of pavement surface.

3.2 Generic Recommendations

The respective implementing agencies including NHAI, contractor & PIU etc. identified in earlier

section should follow the following recommendations.

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) ofAilahabad 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. If the fire is beyond control and spreads further then

immediately inform the security post who would in turn inform the district authorities and

call for extemal help.

> First aid team will provide immediate relief to the injured personnel or guests at the scene

of incident.

Recommendation for NHAI

The NHAI, the primary organisation entrusted with the responsibility of developing and maintaining

the highways and road network of India, have a very important role to play in the prevention of

accidents on the highway, information dissemination and contact information of emergency response

agencies.

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 compliance2. 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 associa tion with


* 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)

Noise level Monitoring

The measurements for monitoring noise levels would be carried out at all designated locations alongall contract package in accordance to the Ambient Noise Standards formulated by Central PollutionControl Board (CPCB) in 1989. These standards have been described in table 3.4. Sound pressurelevels would be monitored on twenty-four hour basis. Noise should be recorded at a "A" weightedfrequency using a " slow time response mode" of the measuring instrument. The location, durationand the noise pollution parameters will be monitored and the responsible institutional arrangementsare detailed out in the following sections.

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.

The monitoring plan for the various performance indicators of the project in the construction and

operation stages is summarized in table 3.5.

Reporting Arrangements

41 Introduction

The Monitoring and Evaluation of the performance indicators are critical activities inimplementation of the Project. Monitoring involves periodic checking to ascertainweather activities are going according to the plans. It provides the necessary feedback forproject management to keep the program on schedule. The rationale for a reportingsystem is based on accountability to ensure that the measures proposed as part of theEnvironmental Management Plan get implemented in the project. Therefore there is aneed for evaluation of institutional capacity of the stakeholders including the organizationstructure and reporting structure. This chapter summarizes the existing institutionalstructure, proposed reporting structure and training needs for NHAI for implementingEMP.

42 ExIsting Institutional Arrangements

The existing organization structure of NHAI and other stakeholders is summarized in thefollowing 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 effectiveimplementation 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 beenestablished for each of these packages. International consultants have been appointed forcarrying out the feasibility study and preparation of the Detailed Project Reports anddesigns for four-laning, of the project packages.

Prolect ImPlementatlon Units

These are separate NHAI units established at the project locations for each of the projectpackages, with a Project Director (PD) as its head. The Project Director is assisted on alltechnical issues related to environment and R&R by a manager. The various Project Directors, inturn report to the General Manager (WB), who is responsible for the co-ordination of the projectpreparation activities of the various project packages.

The review of the preparation of the Environmental and Social assessments for the projectand ensuring effective implementation of the Environmental Management Plan/Resettlement Action Plan will be carried out by the GM (Environment) at Corporateoffice 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 addressthe environmental/social issues likely to result because of the project. To assess, adviseand 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 EnvironmentalUnit is headed by the General Manager (Environment), and is assisted by ONE DeputyGeneral Manager (DGM) and one manager.

The Environmental Unit is responsible for the co-ordination of the environmental andsocial issues of the various project packages and shall work in close interaction with theenvironmental managers at the various PlUs.

In association with


4.3 Other Stakeholders

The other stakeholders, which assist NHAI include DPR consultants, independentreviewers, supervision consultants, NGO's and contractors.

DPR Consultants

The DPR Consultants assist the PIU during project preparation. The Environmental andSocial experts of the DPR consultants have been responsible for the preparation of EA asper the ToR approved by the World Bank. The major inputs of the DPR consultants endswith submission of draft documents. However, their technical inputs continue for theentire project duration on a limited scale.

Independent Reviewers

Since Allahabad bypass project has been categorised category 'A' project due tocumulative environmental and social impacts, therefore, independent reviewers have beenappointed. The reviewers reviewed the environmental and social assessments carried outby the DPR consultants and have identified missing gaps These missing gaps have beenrectified and consolidated environmental and social assessment have been submitted tothe World Bank and NHAI along with Independent Review report.

Supervision Consultants (SC)

The project envisages the use of Supervision Consultants for the implementation stage toassist the PIU during construction stage. The SC will assume the role of the Engineer andwill have the powers and responsibility for the approval of bills, etc. normally vested withthe client. These consultants will be selected through International Competitive Bidding(ICB) and it is expected that they will have substantial capability to supervise theimplementation of the environmental component of the project as part of theirassignment. Implicitly, the construction supervision consultants are expected to havespecialists to advice and co-ordinate implementation of the measures developed as part ofthe Environmental Management Plans for various construction packages of the Allahabadbypass.

Non-Governmental Organisations

The provisions envisaged in the RAP shall be implemented by Non-GovernmentalOrganisations contracted for the purpose by the PIU. Their mandate is to monitor theprogress and implementation of the proposed measures. A representative of the NGO willalso be a part of the District Level Committee which will decide the replacement value ofland and properties to be acquired. One representative of the NGO will also be a part ofthe Grievance Redressal Committee for each district.

Contractors

The execution of the works will be responsibility of the contractor. Three contractors willbe appointed by International Competitive Bids (ICB) for the three packages of thisproject. It is expected that the environmental measures will also be implemented by thesame contractors who will execute the road and bridge work It will be ensured that eachcontractor will have enough environmental/social expertise to incorporate

In association with


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 toimplement 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 aregoing simultaneously. Additional social and environmental managers need to be inductedto 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 subpackages of Package III. It has been estimated that the present resources of the PIU willbe extremely stretched due to overlap of construction activities. It is thereforerecommended that a separate environmental manager be inducted at PIU level sincemanager technical looking after environmental aspects will find it difficult to cope upwith 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 & responsibilitiesin the project implementation is presented in the following sections.

Prolect Implementation Unit

* Strengthening of NHAI's PIU environment team by recruiting at least oneenvironmental manager responsible for looking after environment issues.

* PIR needs to identify laboratories approved by UP Pollution Control Board anddevelop a database of laboratories to carryout onsite monitoring formulated inEMP.

* The contractor and supervision consultants should be informed of this database sothat they can procure services of only empanelled laboratories for monitoring.

In association with


* PIU need to be adequately equipped with instrumentation and should have trainedmanpower to address environmental emergencies.

* There is a need to develop an organized reporting system in association withheadquarters.

Enuironmental Reportng System lERSI

Environmental monitoring involves periodic checking to ascertain whether environmentalactivities are going according to the EMP. It provides the necessary feedback for projectmanagement to keep the program on schedule. The evaluation is essentially a summingup of the project assessment of whether those activities have actually achieved theiroutcomes. The important features of ERS are summarized below.

* The reporting system will operate linearly with the contractor who is at the lowestrung of the implementation system. The contractor will report to the SupervisionConsultant, who in turn shall report to the PIU and Environmental and SocialDevelopment unit of NHAI at corporate office.

* All reporting by the contractor and Supervision Consultant shall be on a quarterlybasis.

* The ESDU in association with PIU shall be responsible for preparing targets foreach of the identified EMP activities.

* All subsequent reporting by the contractor shall be monitored as per the targets setby them before the contractors move on to the site.

* The compliance monitoring and the progress reports on environmentalcomponents may be clubbed together and submitted to the ESDU at corporateoffice and PIU, quarterly during the implementation period.

* The operation stage monitoring reports may be annual or biannual, provided theProject Environmental Completion Report shows that the implementation wassatisfactory.

* During the implementation period, a compliance report may include description ofthe items of EMP, which were not complied with by any of the responsibleagencies. This would help in rationalising the implementation of the EMP duringthe remaining duration of implementation. Solutions for further effectiveimplementation should also come out as a result of the compliance monitoringreports.

* Responsibilities for overseeing will rest with the Supervision Consultant's staffreporting to the PIU and ESDU corporate office.

* Capacity to quantitatively monitor relevant ecological parameters would be anadvantage but monitoring will primarily involve ensuring that actions taken are inaccordance with contract and specification clauses, and specified mitigationmeasures as per the EMP.

* Photographic records will also be established to provide useful environmentalmonitoring 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 andMonitoring Systems for various stages of construction and related activities havebeen 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

Internalizing Environmental Exuertise In the NHAI

It is expected that NHAI will develop internal capability over the next decade in thehighways sector in India, which needs to be fully internalsed. It is important that thereshould be substantial environmental capacity beyond the staff, directly responsible forimplementing the EMP in different projects. This may be achieved through training anddissemination of information.

4. Operationalisation

Operationalization of the environmental setup for this project would involve thefollowing 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) arealready working for the project's environmental and social components. An additionalmanagerial staff will be inducted when implementation begins. It would be advantageousif this manager has post-graduate qualifications in Environmental Engineering or previousexperience 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 theservices of any other agency, such as educational institutions for monitoring, if foundessential, during the implementation stage.

Supervision Consultants (SC)

The NHAI will appoint supervision consultant selected through International CompetitiveBid (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 ofEMP, need to be trained on the effective implementation of the environmental issues. Toensure the success of the proposed implementation set up, there is a need for training andskill upgradation.

As part of the TNHP and GTRIP project different training program have been worked outby NHAI to incorporate the project as well as the intermediate - term capacity buildingneeds of the NHAI.

Looking into the potential requirements of each of the target groups, following trainingmodules are suggested as part of ABP.

(B) Two stakes as above driven firmly on either side of the tree with a cross bar to

which the stem is attached. Suitable for bare- rooted or Ball material.

(C) A single stake driven in at an angle at 45 degrees and leaning towards the

prevailing wind, the stem just below the lowest branch being attached to the stake.

Suitable for small bare- rooted or Ball material

(D) For plant material 3m to 4.5m high with a single stem a three- wire adjustable guy

system may be used in exposed situations.

The end of stake should be pointed and the lower Im to 1.2m should be coated with a

non-injurious wood preservative allowing at least 150mm above ground level.

Tying

Each tree should be firmly secured to the stake so as to prevent excessive movement.

Abrasion must be avoided by using a buffer, rubber or Hessian, between the tree and

stake. The tree should be secured at a point just below its lowest branch, and also just

above ground level; nonmally two ties should be used for tree. These should be adjusted

or replaced to allow for growth.
