Class V

Class V injection facilities inject non-hazardous commercial, industrial, or municipal waste directly into or above a usable aquifer. Class V facilities may not inject hazardous waste.  Class V facilities include a variety of wells, drainfields, drywells, and leachfields.  All Class V facilities are regulated under W.S. 35-11-301 and WQRR Chapter 27. You may download the current version from the Secretary of State's Office website.
