The volume summarizes results and policy alternatives identified during a 2-year pollution prevention study of Amoco Oil Company's Yorktown Virginia Refinery, jointly sponsored as a cooperative effort of Amoco Corporation and the United States Environmental Protection Agency. A significant finding of the study was that at the facility, current and expected environmental regulatory requirements can be achieved for 20-25% of the cost of current mandated approaches. Major recommendations are: (1) Government and industry need to explore opportunities to produce better environmental results more cost effectively; (2) The authors need to improve environmental release data collection, analysis, and management; (3) EPA should provide incentives for conducting facility-wide assessments and developing multi-media release reduction strategies; (4) The authors should encourage additional public-private partnerships on environmental management issues; (5) EPA and the petroleum industry should conduct research on the potential health and ecological effects of VOCs.
