INTRODUCTION A. Overview 1. The Government of Karnataka (GoK) through the Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC) has prepared the North Karnataka Urban Sector Investment Programme (NKUSIP) under the Asian Development Bank assistance. The proposed NKUSIP is the logical follow-on investment program to the ongoing Loan 2312-IND. The NKUSIP is being formulated as a sector loan with a multitranche financing facility modality. The project goal is to facilitate economic growth in the five towns of North Karnataka under Package 3 and bring about urban basic services to the citizens that are environmentally sound and operationally sustainable. Outputs from several vital studies, financial assessment and social and Environmental Assessment, etc, have formed the backbone for the programme appraisal leading to approval of loan. Initial Environmental Examination (IEE) Report is considered as an important tool for incorporating environmental concerns at the project level. IEE should be carried out as early as the project planning stage as part of feasibility thus it can assure that the project will be environmentally feasible. 2. Initial Environmental Examination (IEE) of the proposed sub projects in ’Basavakalyan Town’ is provided in this section following the guidelines of Asian Development Bank’s (ADB) Environment Policy (2002) and Environmental Assessment Guidelines (EAG) (2003). As the Sewerage System and Water Supply Plan, Slum Improvement Works for Basavakalyan Town in Phase I aim to improve the quality of life by significantly improving the environmental conditions of the city, the environmental impacts are expected to be low and hence a rapid assessment has been performed. The Environmental Assessment is based on reconnaissance surveys, primary and secondary data obtained during actual field surveys, analysis, and from various concerned government departments. The report describes environmental baseline condition of city, existing environmental policies and relevant legislations and administrative framework applicable for the proposed sub component of NKUSIP Package-3. The part covers environmental impacts and mitigation measures for construction and operation phases of the project. Categorisation of project impact has been identified. The Environmental Management Plan and Monitoring Plan are substantiating the IEE report. The IEE report has been prepared as per requirements of ToR of Programme Consultants’ Services. B. Methodology 3. Environmental Assessment (EA) is the process in which environmental factors are integrated into project planning and decision making in details so as to achieve ecologically sustainable development. It aims
