Required to the eisting alignment, identification and fixation of alignments of short bypasses, identification of locations of service roads, identification, location and design of toll plazas etc necessary arboniculture along the highway and plantation on the median stnps compatble with the surrounding landscape shall be suitably suggested. " T:.. 7he Consultant shall undertake a detailed environmental study in accordance with the standards prescnbed by Gol and Word Bank and will make suitable recommendations and prepare appropnate mitigation plan and resettement action plans. The Engineering design of the project will absorb all acceptable recommendations emerging out of the environmental studies."  C. ENVIRONMENTAL MANAGEMENT PLAN C.1 INTRODUCTION The Environmental Management Plan (EMP) consists of the set of mitigation, monitoring and institutional measures to be taken during the design, construction and operation stages of the project to eliminate adverse environmental impacts, to offset them, or to reduce them to acceptable levels. The plan also includes the actions needed for the implementation of these measures. The major components of the Environmental Management Plan are * Mitigation of potentially adverse impacts * Monitoring during project implementation and operation * Institutional Capacity Building and Training * Implementation Schedule and Environmental Cost Estimates * Integration of EMP with Project planning, design, construction and operation. C.2 OBJECTIVES OF THE EMP The main aim of the Environmental Management Plan is to ensure that the various adverse impacts are mitigated and the positive impacts are enhanced. The objectives of the EMP at various stages of the project planning and implementation are as follows: C.2.1 Design Stage - To have minimum impact on road side trees, forestation and ground cover * To keep land acquisition and building demolition at a minimum a To provide maximum safety to the highway users and road side communities as well as segregation of local and slow moving traffic in the congested areas e To develop a design that incorporates environmental safeguards and * To provide mitigation measures to all expected environmental degradation C.2.2 Construction Stage * To prevent and reduce the negative environmental impacts of the project by implementable mitigation measures, to be carried out by the Contractor. e To ensure that the provisions of the EMP are strictly followed and implemented by strengthening implementation arrangements. C.2.3 Operation Stage * To prevent deterioration of environment components of air, water, soil, noise etc. * To improve the safety of the highway users and road side communities C.3 MEETING THE EMP OBJECTIVES The following commitments are important to effectively implement the EMP and have been adopted to address the various objectives of the EMP. C.3.1 Commitment to address environmental health, safety and social impacts To improve the environmental conditions, including areas such as environmental health, safety and social impacts, measures have been suggested and included as part of the EMP. Such measures have been continuously developed as an interactive process. 3  C.3.2 Commitment for constant dialogue with the public and interested stakeholders The community consultation process was carried out right from the inception stage of the project. Continuous dialogue with local inhabitants and stakeholders including public agencies has been established on various environmental issues to obtain their feedback. Consultation would continue throughout the implementation Stage of the project. C.3.3 Commitment related to training For the effective implementation of the EMP measures proposed, sustainable institutional arrangements have been proposed. To educate and train the PIU, the personnel of the Construction Supervision Consultants and the Contractors, an extensive training schedule has been worked out as part of the consolidated EIA report for the project. The training programme will be implemented as per the schedule proposed. C.3.4 Commitment to meet legal requirements The legal requirements, procedures, etc., that are necessary or mandatory for the commencement of the project have been met. The conditions stipulated by the various Statutory Authorities as the State Pollution Control Boards, Forest Departments etc. will be complied with. D. CRITICAL IMPACTS TO BE ADDRESSED - PACKAGE IV-B On the basis of the assessment of the potential impacts, the critical environmental components that need to be addressed in the Environmental Management Plan have been identified. The most critical issues to be addressed at various locations along the project corridor are described in Table 2 below.
