Standards Support and Environmental Impact Statement. Volume 2. Promulgated Standards of Performance for Lignite-Fired Steam Generators.

摘要

A standard of performance for the control of emissions of nitrogen oxides from new and modified lignite-fired steam generators is being promulgated under the authority of section III of the Clean Air Act. When standards of performance for large steam generators were promulgated under Subpart D of Part 60,lignite-fired units were exempted from the nitrogen oxides standard (the sulfur dioxide and particulate matter standards are applicable to lignite-firing) because of a lack of data on attainable levels of emission from such units. Since then,sufficient data have been obtained to propose and promulgate a standard. This document contains summaries of public comments on the proposed standards,EPA responses, a discussion of differences between the proposed and promulgated standards,and the final environmental impact statement as submitted to the Council on Environmental Quality.
