The project will be implemented over an eight-year period from 2014 to 2022. The program is also proposed to be implemented using a multitranche financing facility (MFF) of Asian Development Bank (ADB). At present KEIIP Tranches 1 and 2 projects are under implementation. ADB requires the consideration of environmental issues in all aspects of the bank’s operations, and the requirements for environmental assessment are described in ADB’s Safeguard Policy Statement (SPS), 2009. This states that ADB needs environmental assessment of all project loans, program loans, sector loans, sector development program loans, and loans involving financial intermediaries, and private sector loans. This initial environmental examination (IEE) report is for one priority sewerage and drainage (S&D) subproject of Tranche 3 “improvement of S&D network and construction of a pumping station in Alipore body guard line (BGL) premises in ward 74 and laying of sewer line along Diamond Harbour Road by Micro tunneling method and cut & cover method”. Tranche 3 loan will be signed later. Construction work for this specific Tranche 3 subproject will commence in early 2018 and will be completed in by 2020. The IEE aims to (i) provide critical facts, significant finding, and recommended actions; (ii) present the national and local legal and institutional framework within which the environmental assessment has been carried out; (iii) provide information on existing geographic, ecological, social and temporal context including associated facilities within the subproject’s area of influence; (iv) assess the subproject’s likely positive and negative direct and indirect impacts to physical, biological, socioeconomic, and physical cultural resources in the subproject’s area of influence; (v) identify mitigation measures and any residual negative impacts that cannot be mitigated; (vi) describe the process undertaken during project design to engage stakeholders and the planned information disclosure measures and the process for carrying out consultation with affected people and facilitating their participation during project implementation; (vii) describe the subproject’s grievance redress mechanism for resolving complaints about environmental performance; (viii) present the set of mitigation measures to be undertaken to avoid, reduce, mitigate, or compensate for adverse environmental impacts; (ix) describe the monitoring measures and reporting procedures to ensure early detection of conditions that necessitate particular mitigation measures; and (x) identify who is responsible for carrying out the mitigation and monitoring measures. Potential negative impacts were identified in relation to pre-construction, construction and operation of the improved infrastructure, but no permanent environmental impacts were identified as being due to either the subproject design or location. Mitigation measures have been developed to reduce all negative impacts to acceptable levels. These were discussed with specialists responsible for the engineering aspects, and as a result some measures have already been included in the designs for the infrastructure. This means that the number of impacts and their significance have already been reduced by amending the design. The public participation processes have been undertaken during project detailed design stage which ensures that stakeholders are engaged during the preparation/ finalization of the IEE. The ii planned information disclosure measures and process for carrying out consultation with affected people will facilitate their participation during project implementation. The subproject’s grievance redress mechanism (GRM) will provide the citizens with a platform for redress of their grievances and describes the informal and formal channels, time frame and mechanisms for resolving complaints about environmental performance. The environmental management plan (EMP) will guide the environmentally-sound construction of the subproject and ensure efficient
