Hazardous Air Pollutant Emissions from Mercury Cell Chlor-Alkali Plants. Background Information Document for Proposed Standards

摘要

This background information document (BID) provides information relevant to the proposal of national emission standards for hazardous air pollutants (NESHAP) for limiting mercury emissions from mercury cell chlor-alkali plants. The standards are being developed according to section 112(d) of Title III of the Clean Air Act (CAA) as amended in 1990. Chapter 2 presents a description of the mercury cell chlor-alkali industry and process. Chapter 3 discusses the techniques sued to control mercury emissions from the mercury emission sources at mercury cell chlor-alkali plants. Chapter 4 describes the regulatory alternatives considered by the Environmental Protection Agency (EPA) for proposal. Chapters 5 and 6 discuss the estimation of environmental and energy impacts and cost impacts, respectively, of the regulatory alternatives on the industry. Chapter 7 presents the detailed rationale behind the selection of the proposed NESHAP.
