Remediation of refinery wastes is regulated by three major federal environmental statutes: the Clean Air Act, the Clean Water Act, and the Resource Conservation and Recovery Act (RCRA); other statutes apply, but to a lesser degree. During the past two years, RCRA's rules have effectively outlawed the passive biological treatment of primary refinery waste sludges in waste ponds and lagoons, even though the law recommends active biological treatment as the second stage in the waste treatment train. RCRA's land disposal restrictions may also outlaw land farming treatment for the bottom sludges involved in crude oil storage. Since 1980, when the U.S. Environmental Protection Agency listed an initial group of five waste streams as hazardous, the agency has listed two more waste streams and twenty‐five organic constituents, several found in petroleum wastes. Now it is about to list fourteen more petroleum refining wastes and is studying the addition of fifteen more waste streams. Treatment standards and restrictions have also been promulgated. This article explores the biotreatment techniques and technologies that are still available to petroleum and environmental engineers.
