Evaluation of Air Pollution Regulatory Strategies for Gasoline Marketing Industry - Executive Summary

摘要

The gasoline marketing industry (bulk terminals, bulk plants, service station storage tanks, and service station vehicle refueling operations) emit to the atmosphere several organic compounds of concern. These include: volatile organic compounds (VOC), which contribute to ozone formation; benzene, which has been listed as a hazardous air pollutant based on human evidence of carcinogencity; and ethylene dichloride (EDC), ethylene dibromide (EDB), and gasoline vapors, for which there is animal evidence of carcinogencity. This report contains a summary of the analysis conducted concerning the health, emission, cost, and economic impacts of several regulatory strategies for addressing organic compound emissions from gasoline marketing sources. (The full report is contained in EPA Document PB84-231075). The regulatory strategies evaluated are: (1) service station controls (Stage II) for vehicle refueling emissions only in areas requiring additional VOC control to attain the national ozone ambient standard; (2) service station controls (Stage II) for vehicle refueling emissions on a nationwide basis; (3) onboard vehicle controls for vehicle refueling emissions on a nationwide basis; (4) bulk terminal, bulk plant, and service station storage tank controls on a nationwide basis; and (5) various combinations of these alternatives.
