Comparison: State vs. Federal
• Rules. As under the federal rules, Oklahoma prohibits the construction, installation, or operation of Class IV wells. Although the Oklahoma regulations allow hazardous waste to be injected into underground Class I wells, currently the state has no Class I wells permitted to dispose of hazardous waste.
Oklahoma has adopted the federal permit-by-rule option for underground injection wells. Wells that meet the permit-by-rule requirements (including the requirement that the facility have an underground injection well permit under the federal Safe Drinking Water Act (SDWA)) are deemed to have a hazardous waste disposal facility permit; they do not have to apply for one. In addition, Oklahoma requires facilities disposing of waste in Class I, Class III, or Class V injection wells in Oklahoma to pay various state fees.
