Kecjprocating Internal Combustion Engines (RICE) I New England I US EPA 1. non -emergency situations if no financial arrangement 2. local reliability as part of a financial arrangement with another entity if specific criteria met (existing RICE at area sources of HAP only) 3, peak shaving until May 3, 2014 (existing RICE at area sources of HAP only) if part of a peak shaving (load management) program with the local distribution system operator and the power is provided only to the facility or to support the local distribution system The RICE rule Applies to: 1. Engines >500 Horsepower (HP) at major source of HAP: Existing engines if constructed before December 19, 2002 New engines if constructed on or after December 19, 2002 Reconstructed engines if reconstruction began on or after December 19, 2002 2. Engines :5500 HP located at major source of HAP and engines of all horsepower located at an area source of HAP: Existing engines If constructed before June 12, 2006 New engines if constructed on or after June 12, 2006 Reconstructed engines if reconstruction began on or after June 12, 2006 Top M Page Determining RICE Rule Compliance Requirements RICE Rule requirements are complex — but they are similar for several groups of engines, as summarized in the tables below. Key Definitions for Terms Used in Compliance Summary Tables Below: PJ: Compression Ignition (diesel) SI: Spark Ignition (gas including natural gas, landfill gas, gasoline, propane, etc.) 2SLB: 2 -stroke lean bum 4SLB:4-stroke lean bum 4SRB: 4 -stroke rich burn • 4_$:4 -stroke LFGIDG: landfill gas/digester gas ULSD: Ultra Low Sulfur Diesel Notes: 2 -stroke: power cycle completed in 1 revolution of crankshaft 4 -stroke: power cycle completed in 2 revolutions of crankshaft Leen bum: higher air/fuel ratio (fuel -lean) Rich bum: lower airffuel ratio (fuel-dch) 2 ol' 5 RICE (PDF) (r: f, s, ti.. EPA New England is eager to work with trade associations, munidpalities, community groups and others to provide information to any sources affected by these new regulations.
