NO/Sub X/ Regulatory Changes and the Electric Utility: A Guidance Manual for Air Quality Modeling in Planning, Siting, and Emissions Control. Final Report

摘要

Several regulatory changes that are at or nearing the proposed rule stage are likely to influence requirements for the control of nitrogen oxide emissions from power plants. The pending changes, all mandated by the 1977 Amendments to the Clean Air Act, include the possible requirement for a short-term ambient standard for NO sub 2 , prevention of significant deterioration rules for NO sub 2 , and visibility protection regulations. This Guidance Manual is a reference document designed primarily for the utility reader. It first examines the potential implications of the possible NO/sub x/-related regulations, reviews current regulatory and permitting requirements, and surveys NO/sub x/ ccontrol technology costs and capability. Then, in subsequent sections, it discusses the conduct of a NO sub 2 air quality impact analysis that is technically adequate and yet no more costly than necessary. Topics discussed include the designing of a modeling strategy; the conducting of a screening analysis; and the selecting of appropriate models, as well as their data requirements and costs. The Guidance Manual is supplemented by a six-volume reference set, collectively referred to as the Technical Support Document. These volumes provide supporting technical reference material.
