Comparison: State vs. Federal

Rules. Oklahoma has incorporated by reference the federal hazardous waste storage rules for permitted facilities and on-site storage by generators. The state has added several more requirements that make its rules more stringent than the federal storage rules. The more stringent state hazardous waste storage rules are in connection with permits and fees for hazardous waste storage facilities.

Administration and enforcement. DEQ's Land Protection Division administers and enforces the hazardous waste storage rules in Oklahoma.

State Requirements


Oklahoma's permit and operation requirements for hazardous waste storage facilities include the federal standards plus the state's additional requirements in connection with the permitting process, permit conditions, and on-site inspectors. Unlike the federal rules, Oklahoma requires storage facilities to pay various fees, including a permit application fee and an annual monitoring fee. For additional information regarding the state's permit application process, additional permit conditions, and facility fees, see the state section TSDF PERMITS.
