Oklahoma adopts by reference the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in the state as of September 15, 2018, which includes standards that allow generators to treat hazardous waste on-site. See the state sections ACCUMULATION TIME, HAZARDOUS WASTE STORAGE, and LAND DISPOSAL RESTRICTIONS to review the requirements applicable to generators treating hazardous waste on-site.
