The document sumarizes the results of the analyses perfomed in support of the Proposed Rulemaking (FRM) entitled, "Control of Air Pollution: Determination of Significance for Nonroad Sources and Emission Standards for New Nonroad Compression-Ignition Engines at or above 37 Kilowatts (50 hp), 59 FR 31306 (June 17, 1994). This PRM will regulate all new nonroad compression-ignition engines greater than or equal to 37 kilowatts (50 hp), except engines which propel or are used on marine vessels, aircraft engines, engines which propel locomotives, and engines regulated by the Mining, Safety, and Health Administration. The regulated engines are hereafter referred to as "nonroad large CI engines."
The environmental impact, costs and cost effectiveness of the regulation are assessed, as well as other associated benefits. Includes quantified impacts on emissions, monetized benefits to crops, and qualitative discussion of benefits to health and welfare. Economic analysis includes (1) variable hardware costs, (2) production life cycle fixed costs, (3) annual fixed costs, and (4) consumer costs, including the increase in retail price and engine generating costs.
