Recent EPA guidance clarified expectations around used oil storage labeling, manifest retention, and container condition at generator sites. For most of our customers, the bottom line is simple: Michigan Oil already handles compliant manifests, chain-of-custody documentation, and proper transport ÔÇö but you should double-check that your on-site storage containers are clearly labeled and free of leaks. If you want a compliance walk-through at your shop, our team is happy to visit. No charge, no pressure.
