Comparison: State vs. Federal

Rules. Oklahoma adopts by reference the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in Oklahoma as of September 15, 2018, which includes the federal contingency plan requirements for large quantity generators (LQGs). The state also adopts by reference the federal contingency plan requirements applicable to permitted hazardous waste treatment, storage, and disposal facilities (TSDFs) and interim-status TSDFs. However, unlike the federal rules, Oklahoma requires TSDFs to prepare an additional state plan, called an "emergency plan," that follows the contingency plan criteria of 40 CFR 264 Subpart D and is approved by a majority of nearby property owners.

Administration and enforcement. The Oklahoma Department of Environmental Quality's (DEQ) Land Protection Division administers and enforces the contingency plan rules and the emergency plan rules in Oklahoma.
