Class I
All commercial disposal wells in Wyoming are regulated by the UIC Program as Class I injection wells. Class I wells inject industrial, municipal and hazardous wastes below the deepest Underground Source of Drinking Water (USDW). Currently, all permitted Class I wells are for the injection of non-hazardous waste. WQRR Chapter 27 governs the installation and operation of Class I wells. You may download the current version from the Secretary of State’s Office website.
The Class I Well Application form and instructions are located in the “Forms and Guidance” tab above.
The UIC Program strongly encourages applicants to schedule a pre-application meeting to discuss the project in general and potential concerns. The UIC Program will not make permitting or technical decisions at this meeting.
Please be advised that the UIC Program requires Class I permit renewals to be submitted 180 days prior to permit expiration.
