Development of Pollution Prevention and Waste Minimization Profiles Emphasizing PBT Chemical Reductions for Petroleum Refineries

Wyoming Department of Environmental Quality (WDEQ) and U.S. EPA Region 8

August, 2004

Seven petroleum refineries in Region 8 (Wyoming, North Dakota, Montana and Colorado) were visited and evaluated to assess the industry’s voluntary initiatives to implement Pollution Prevention/Waste Minimization (P2/WM) projects. There was emphasis on Bi-National Strategy (BNS), Persistent, Bioaccumulative and Toxic (PBT) contaminants and consideration was also given to more conventional pollutants yielding significant environmental benefits. The report categorizes P2/WM initiatives into two groups: 1) "minimum,” conventional efforts that have been voluntarily “self-imposed” by most refiners in the industry and; 2) more "innovative" and case-specific initiatives.

Evidence provided indicates these initiatives yielded a benefit of approximately 10,000 tons per year (tpy) in voluntary reductions of combined air emissions, water effluents and waste generation rates during the project evaluation timeframe, and are expected to continue for the operating life of the respective facilities. Furthermore, due to industrial competition and evolving P2/WM efforts, it is expected that the seven Region 8 refineries will meet or exceed the 10,000 tons per year reduction level.

Although this is the final report for this Grant, work will continue under a separate Grant, administered by the EPA's Solid and Hazardous Waste Program. Besides extending the timeframe of the recently completed project, this new project will expand the scope of effort to include 33 RCRA PBT priority chemicals.
