KMRI SMG ASSET COMPANY PVT LTD 4 MW Biomass Combined Heat & Power Plant Project, Loluwagoda, Mirigama ENVIRONMENTAL IMPACT ASSESSMENT (EIA) Report 8/28/2015 This EIA Report is prepared for KMRI SMG Asset Company Ltd., which is an incorporated private company engaged in power generation. The purpose is to assess the environmental and social impacts of the proposed project in keeping with environmental and social safeguard policies, laws and regulations of both Sri Lanka as well as international best practices, in particular the operational guidelines of the European Investment Bank. The proposed power generation project complements Sri Lanka’s energy policies. The project will have an installed capacity to generate 4.0 MW of electricity (combined power & heat) to be partly used by the existing industry owned by Silver Mills Group and the balance to be connected to the national grid. The project is being constructed on a land where the Silver Mills Group has its coconut processing plant being operated for the last few decades. The fuel wood supply chain lies within a radius of 50 km from the location of the power plant which includes villages in the Kegalle, Kurunegala and Gampaha Districts of Sri Lanka Page 0 EIA Report
