Assessment Topic

Final decisions have been made on regulation of benzene emissions from existing and new coke by-product recovery plants, benzene storage vessels, equipment leaks, and ethylbenzene/styrene process vents. These decisions implement Section 112 of the Clean Air Act and are based on the Administrator's determination of June 8, 1977 (42 FR 29332), that benzene presents a significant risk to human health as a result of air emissions from one or more stationary source categories, and is therefore a hazardous air pollutant.
In June 1984, EPA promulgated standards for benzene equipment leaks and coke by-product recovery plants, and withdrew proposed standards for EB/S process vents, benzene storage vessels, and maleic anhydride process vents. In 1987, EPA decided to reconsider the promulgated standard in light of recent court cases. On July 28, 1988, EPA proposed four alternative policy approaches for all sources except maleic anhydride process vents (because benzene was no longer used to make maleic anhydride) (see A.88.7) .

This document contains a summary of the comments on the proposal of these standards in the Federal Register (53 FR 28496), the EPA's response to these comments, and a summary of the health, environmental and economic impacts of the final standards. The file contains Chapter 1 (Introduction) and 7(Risk Assessment comment/response).
