SECTION 31-47.3-2
§ 31-47.3-2 Definitions. – When used in this chapter:
(1) "Best available retrofit technology" means technology,verified by the United States Environmental Protection Agency or California AirResources Board (CARB) for achieving reductions in particulate matter emissionsat the highest classification level for diesel emission control strategies thatis applicable to the particular engine and application. Such technology shallnot result in a net increase in nitrogen oxides.
(2) "Heavy duty vehicle" or "vehicle" means any on-road ornonroad vehicle powered by diesel fuel and having a gross vehicle weight ofgreater than fourteen thousand (14,000) pounds.
(3) "Director" refers to the director of the department ofenvironmental management (DEM).
(4) "Level 1 control" means a verified diesel emissioncontrol device that achieves a particulate matter (PM) reduction of twenty-fivepercent (25%) or more compared to uncontrolled engine emissions levels.
(5) "Level 2 control" means a verified diesel emissioncontrol device that achieves a particulate matter (PM) emission reduction offifty percent (50%) or more compared to uncontrolled engine emission levels.
(6) "Level 3 control" means a verified diesel emissioncontrol device that achieves a particulate matter (PM) emission reduction ofeighty-five percent (85%) or more compared to uncontrolled engine emissionlevels, or that reduces emissions to less than or equal to one one-hundredth(0.01) grams of (PM) per brake horsepower-hour. Level 3 control includesrepowering or replacing the existing diesel engine with an engine meeting USEPA's 2007 Heavy-duty Highway Diesel Standards, or in the case of a nonroadengine, an engine meeting the US EPA's Tier 4 Nonroad Diesel Standards.
(7) "Closed crankcase ventilation system (CCV)" means asystem that separates oil and other contaminant from the blow-by gases androutes the blow-by gases into a diesel engine's intake system downstream of airfilter.
(8) "Full-sized school bus" means a school bus, as defined in(Rhode Island general law) § (31-1-3), which is a type 1 diesel schoolbus, including spare buses operated by or under contract to a school district,but not including emergency contingency vehicles or low usage vehicles.
(9) "Model year 2007 emission standards" means enginestandards promulgated by the federal Environmental Protection Agency in 40 CFRParts 69, 80 and 86.
(10) "Verified emissions control device" means a device thathas been verified by the federal Environmental Protection Agency or theCalifornia Air Resources Board to reduce particulate matter emissions by agiven amount.
