The California Air Resources Board (CARE) has verified specific'.alternative diesel fuel <br /> blends.for NQx;`and. Plvl emission reduction Only fuels;that have been certified.by GARB, should be <br /> used - Information on biodiesel;can be found on CARB's website at http:l/www.arb.ca.goyffu6lsldiesell <br /> altdiesel/altdiesel.htmand.,.the EPA's website- at http://www.epa.gov/oms/models/biodsi.htm. The <br /> applicant should-also:use CARE certified.:alternative-:fueled.engines in construction equipment where <br /> practicable. 'Alternative fueled equipment may powered by Compressed Natural Gas (CNG), Liquid <br /> Propane Gas (LPG), electric motors, or other CARE`certified off-road technologies: To find engines <br /> certified by the.CARB, see their cert cation websitee.http;l/www.arb caaov/mspr6o/offroad/certicert php,. <br /> For more information on any of the technologies fisted. above, please contact Mr. Chris Acree, Senior Air. <br /> Quality.Specialist, at-(559)'230=5829. <br /> • Construction equipment.should have engines.that meet the current off-road-engine emission standard <br /> (as certified.by the CARB), or be re-powered with an engine that meets this standard. Tier I, Tier II and <br /> Tier III engines have significantly less NOx and PM emissions compared to uncontrolled engines. To <br /> find engines certified by the CARB, see htt ://www.arb.ca. ovlms ro /offroad/cert/cert. h . This site. <br /> lists engines by type, then manufacturer. The "Executive Order" shows what Tier the engine is certified i <br /> as.
