The Environmental Protection Agency (EPA) Region 8 announces the deletion of the Operable Unit 2 (OU2), Former Screening Plant, of the Libby Asbestos Superfund Site (Site) located in Libby, Montana from the National Priorities List (NPL). The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This partial deletion pertains to all of OU2. Operable Unit 1 (OU1), Former Export Plant; Operable Unit 3 (OU3), Former Vermiculite Mine; Operable Unit 4 and Operable Unit 7 (OU4/OU7), Residential/Commercial Properties of Libby and Troy; Operable Unit 5 (OU5), Former Stimson Lumber Mill; Operable Unit 6 (OU6), BNSF Rail Corridor; and Operable Unit 8 (OU8), Highways and Roadways, are not being considered for deletion as part of this action and will remain on the NPL. The EPA and the State of Montana, through the Department of Environmental Quality (DEQ), have determined that all appropriate response actions under CERCLA, other than operation and maintenance, and five-year reviews, have been completed. However, the deletion of these parcels does not preclude future actions under Superfund.

The Environmental Protection Agency (EPA) is approving a submittal from the State of Wyoming that demonstrates that the Wyoming State Implementation Plan (SIP) meets certain interstate transport requirements of the Clean Air Act (Act or CAA) for the 2008 ozone National Ambient Air Quality Standards (NAAQS). Specifically, the submittal meets the requirement that Wyoming's SIP contain adequate provisions to prohibit emissions in amounts which will interfere with maintenance of the 2008 ozone NAAQS in any other state. The EPA is taking this action pursuant to section 110 of the Clean Air Act (CAA).

This SIP revision also contains a non- interference demonstration, which concludes that removing the oxygenated gasoline program would not interfere with attainment or maintenance of the National Ambient Air Quality Standards (NAAQS). EPA has determined that North Carolina's March 21, 2018, SIP revision is consistent with the applicable provisions of the Clean Air Act (CAA or Act).
