Notice of Intent to Terminate Underground Injection Control General Permits 5C5-1, 5C5-2, and 5C5-3 Coalbed Methane Injection Facilities

Various entities operated Class V nonhazardous waste injection well facilities, permitted by the Wyoming Department of Environmental Quality (WDEQ) Underground Injection Control (UIC) Program under UIC General Permits 5C5-1, 5C5-2, and 5C5-3 located in Campbell, Johnson, and Sheridan Counties, Wyoming. These facilities injected produced water, primarily from commercial production of coalbed methane and were authorized for injection under a General Permit issued by WDEQ. This notice informs the public of the WDEQ's intent to terminate UIC General Permits 5C5-1, 5C5-2, and 5C5-3 as no facilities are operating under these General Permits and any future requests to inject would require operators of these facilities to apply for a UIC Individual Permit.
