Guideline limits apply to facilities operating more than 500 hours per year. Emission levelsshould be evaluated on a one hour average basis and be achieved 95% of annual operating hours.- (a) Compression Ignition (CI) engines may require different emissions values which should be evaluated on a case-by-case basisthrough the EA process.Comparison of the Guideline limits with standards of selected countries / region (as of August 2008):- Natural Gas-fired Reciprocating Engine – NO X• Guideline limits: 200 (SI), 400 (DF)• UK: 100 (CI) , US: Reduce by 90% or more, or alternatively 1.6 g/kWh- Liquid Fuels-fired Reciprocating Engine – NO X (Plant >50 MWth to 25 MWth), India: 1,460 (Urban area & ≤ 75 MWe (≈ 190 MWth), Rural area & ≤ 150 MWe (≈ 380 MWth))- Liquid Fuels-fired Reciprocating Engine – NO X (Plant ≥300 MWth)• Guideline limits: 740 (contingent upon water availability for injection)• UK: 300 (> 25 MWth), India: 740 (Urban area & > 75MWe (≈ 190 MWth), Rural area & > 150 MWe (≈ 380 MWth)- Liquid Fuels-fired Reciprocating Engine – SO 2• Guideline limits: 1,170 or use of ≤ 2% S (Plant >50 MWth to
