National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the OU1 of the Libby Asbestos Superfund Site
The Environmental Protection Agency (EPA) Region 8 is issuing a Notice of Intent to Delete Operable Unit 1 (OU1), Former Export Plant, of the Libby Asbestos Superfund Site (Site), located in Lincoln County, Montana, from the National Priorities List (NPL) and requests public comments on this proposed action. 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). The EPA and the State of Montana (State), through the Department of Environmental Quality (DEQ), have determined that all appropriate response actions at OU1 under CERCLA, other than operation and maintenance and five-year reviews (FYR), have been completed. However, this partial deletion does not preclude future actions under Superfund. This partial deletion pertains only to OU1. Operable Unit 2 (OU2), Former Screening Plant, was deleted from the NPL on April 10, 2019. 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 proposed action and will remain on the NPL.
Air Plan Approval; Washington; Update to the Adoption by Reference, Energy Facility Site Evaluation Council
The Environmental Protection Agency (EPA) is revising the Washington State Implementation Plan (SIP) to approve updates to the Energy Facility Site Evaluation Council (EFSEC) air quality regulations. The EFSEC regulations apply to major energy facilities in the State of Washington and establish permitting requirements and emissions standards for such facilities. The EFSEC regulations primarily adopt by reference the Washington Department of Ecology (Ecology) general air quality regulations for program implementation. We are approving EFSEC's updated adoption by reference to include certain changes to Ecology's general air quality regulations since EFSEC's last adoption by reference, consistent with prior approvals.
Air Plan Approval; Illinois; Emissions Statement Rule Certification for the 2015 Ozone Standard
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) submission from the Illinois Environmental Protection Agency (IEPA) dated May 16, 2019. The submission provides IEPA's certification that its existing emissions statement program, titled ``Annual Emissions Report'', remains in effect and satisfies the Clean Air Act (CAA) emissions statement requirement for the Illinois portions of the Chicago, Illinois-Indiana-Wisconsin (IL-IN-WI) and St. Louis, Missouri-Illinois (MO-IL) nonattainment areas under the 2015 ozone National Ambient Air Quality Standard (NAAQS). Under the CAA, states' SIPs must require stationary sources in ozone nonattainment areas classified as marginal or above to annually report emissions of Volatile Organic Compounds (VOC) and Oxides of Nitrogen (NOX).

Air Plan Approval; Missouri; Sampling Methods for Air Pollution Sources
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the State Implementation Plan (SIP) for the State of Missouri submitted by the State on October 25, 2019. The revisions will amend the SIP by providing a more efficient way to perform emissions sampling on air pollution sources throughout Missouri. The State requested approval of incorporating by reference the federally defined methods for stack testing. These revisions are administrative in nature and do not affect the stringency of the SIP. The EPA's approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
