Draft regulatory impact analysis and oxides of nitrogen pollutant-specific study. Control of air pollution from new motor vehicles and new motor-vehicle engines: gaseous-emission regulations for 1987 and later-model-year light-duty vehicles, light-duty trucks, and heavy-duty engines; particulate-emission regulations for 1987 and later-model year-heavy-duty diesel engines
This document summarizes the results of analyses conducted in support of proposed nitrogen oxide (NOx) emission standards for 1987 and later-model year light duty trucks and the NOx and particulate standards for 1987 and later-model year heavy-duty engines. (49 FR 40258, October 15, 1984). The analyses include consideration of the costs and benefits of the proposed action as well as a comparison of the proposed action with alternative regulatory approaches. The report also includes the environmental impact analyses for NOx and diesel particulate standards.
