ENVIRONMENTAL IMPACT ASSESSMENT (EIA) OF WORLD BANK FINANCED SIDDHIRGANJ 450 MW COMBINED CYCLE POWER PLANT (CCPP) PROJECT SIDDHIRGANJ, NARAYANGAJ Author NEWAZ, M. N. text 2010 2010-12-31 World Bank (WB) book 312822 10.5281/zenodo.17262486 bd0b1ffa-bf79-4a4b-8019-d907607ac887 17262486

Table 6 (A) - Emissions Guidelines (in mgłNm 3 or as indicated) for Reciprocating Engine Note: - Guidelines are applicable for new facilities. - EA may justify more stringent or less stringent limits due to ambient environment, technical and economic considerations provided there is compliance with applicable ambient air quality standards and incremental impacts are minimized. - For projects to rehabilitate existing facilities, case-by-case emission requirements should be established by the EA considering (i) the existing emission levels and impacts on the environment and community health, and (ii) cost and technical feasibility of bringing the existing emission levels to meet these new facilities limits. - EA should demonstrate that emissions do not contribute a significant portion to the attainment of relevant ambient air quality guidelines or standards, and more stringent limits may be required.
