I DHV Consultants BV ENVIRONMENTAL MANAGEMENT PLAN 1. Introduction The main objective of the Consultancy Services is to assist the Government of Bangladesh in preparation of detailed engineering design and detailed environmental studv for the proposed new road (NHBNR) connecting Nalka-Hatikamrul and Bonpara/Ahmedpur. This report includes all findings and assessments with respect to the environmental issues related to NHBNR. It also elaborates an Environmental Management Action Plan for the major interventions of this project in order to mitigate, minimiseor to avoid potential environmentalhazards. 1.1 Terms of Reference During its screeningand assessment procedures, the Feasibility Study (CIECC, 1993) has identified many issues relating to engineering and environmentalaspects as needing more detailed investigation during a detailed design phase. Based on this analysis, the ToR.) that relate directly and indirectly to both the EIA and the EMAP are as follows: Scope of Services Taking into account the findings of the feasibility analysis and preliminary engineering, as well as the relevant environmental impact studies, the Consultants shall perform detailed environmental studies, economic analysis, detailed field surveys, surface and subsurface investigation, including specific soils and materials investigations, laboratory testing and related works, and proceed with the detailed design of the road, bridges and other drainage structures. A master plan for environmental mitigation shall be drawn up, and implementationprocedures established. During the course of their services the Consultant was supposed to carry out inter alia, a detailed environmental Study in accordance with World Bank Operational Directive 4.01 and 4.30 for a Category A project. *) Selectedtext. adoptedand modified.where applicable. from ToR providedby the Client.
