The Project will be implemented over an 8-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 Tranche 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 the one of the sewerage and drainage (S&D) subprojects of Tranche 3 “Construction of pumping stations at (1) Lalababu Nikashi/ Bagjola canal (2) Sakuntala Park, Behala at Node C premises.” Tranche 3 loan will be signed in due course but construction works for specific Tranche 3 subprojects are scheduled to commence during fourth quarter (Q4) of 2018 and will be completed in 24 months, i.e. by Q4 of 2020. Consistent with the Environmental Assessment and Review Framework, the proposed sub project were screened using ADB rapid environmental assessment (REA) checklist of Urban sector and Preliminary Climate Risk Screening for urban sector with wastewater subsector. The environmental screening revealed that no protected or sensitive areas were traversed. All impacts are site specific; few are irreversible and can be readily mitigated supporting an environmental “Category B” classification. IEE for the subproject was published in ADB website in July 2018. Due to change in scope of work of the subproject1 this IEE has been updated to comply with the Environmental Assessment and Review Framework (EARF) which is in consistent with the ADB’s Safeguard Policy Statement (SPS) 2009. IEE was conducted based on preliminary Detailed Design Report (DPR). The IEE covers all activities proposed under the project. The core zone of impact is taken as direct impact of the new construction or reconstruction or rehabilitation of the project component. IEE also covers the direct impact of the sub-project component. Assessment is carried out for all components of environment covering terrestrial and aquatic ecology, soil, water, noise and socio economic aspects. 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; 1 Refer chapter 2 of the report (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
