The purpose of the report is to identify the issues surrounding used oil disposal and reuse. The discussion includes lack of government regulation at some levels, too much regulation at other levels, liability of municipalities in used oil disposal, the potentially hazardous (waste) nature of used oil, and the generation of used oil in Illinois. In addition, mechanisms which will increase used oil collection are reviewed: government regulations, mandatory used oil recycling, recovery of oil from waste oil filters, appropriate levels of permitting for municipal used oil collection facilities, industrial minimization and recycling, government and company involvement, public education, and consumer collection programs. Finally, existing and proposed federal regulations, and Illinois siting requirements are reviewed.
