EXECUTIVE SUMMARY BACKGROUND The Environmental Impact Assessment Report (EIA) on the completion of construction works for Neykovtsi Dam has been developed following the submission of the Environmental Due Diligence Report (EDD) prepared in 2007 by the Ministry of Regional Development and Public Works (MRDPW) to meet the World Bank policy requirements on Environmental Assessment. This document is part of the documentation required for approval of the World Bank assistance requested by the Government of Bulgaria (GoB) to finance activities related to municipal infrastructure development through completion of the Luda Yana water supply dam. This EIA report has been developed to meet the Bank requirements as stated in the ToR (Annex I) and to comply with the effective environmental legislation in the Republic of Bulgaria (RB).
