Processing includes, but is not limited to, blending used oil with virgin petroleum products, blending used oils to meet the fuel specification, filtration, simple distillation, chemical or physical separation and re-refining (§279.1). Processors and re-refiners are subject to the standards codified in Part 279, Subpart F. These include storage standards, such as secondary containment (§279.54), general facility standards (§279.52), recordkeeping requirements (§279.56), and the rebuttable presumption requirements (§279.53).
