This notice announces EPA's approval of the Gila River Indian Community's request to revise/modify certain of its EPA-authorized programs to allow electronic reporting.

The Environmental Protection Agency (EPA) is announcing a 60- day public comment period associated with release of the IRIS Toxicological Review of Perfluorobutanoic acid (PFBA) and Related Compound Ammonium Perfluorobutanoic Acid. The draft document was prepared by the Center for Public Health and Environmental Assessment (CPHEA) within EPA's Office of Research and Development (ORD). EPA is releasing this draft IRIS assessment for public comment in advance of a contract-led peer review. Public comments received will be provided to the external peer reviewers. Eastern Research Group, Inc. (ERG), a contractor to EPA, will convene a public meeting to discuss the draft report with the public during Step 4 of the IRIS Process. The external peer reviewers will consider public comments submitted in response to this notice and provided at the public meeting when reviewing this document. EPA will consider all comments received when revising the document post-peer review. This draft assessment is not final as described in EPA's information quality guidelines, and it does not represent, and should not be construed to represent Agency policy or views.

The Environmental Protection Agency is taking final action to revise regulations governing the production and import of class I ozone-depleting substances in the United States to indefinitely extend the global essential laboratory and analytical use exemption. This exemption currently expires on December 31, 2021, and this final action allows for continued production and import of class I substances in the United States solely for laboratory and analytical uses that have not been identified by the Environmental Protection Agency as nonessential. This final action is taken under the Clean Air Act, and is consistent with a decision by the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer to extend the global laboratory and analytical use exemption indefinitely beyond 2021. The proposed rule associated with this final action was published on August 7, 2020, and we received no adverse comments.

The Environmental Protection Agency (EPA) is proposing a limited approval and limited disapproval of a revision to the Amador Air District's (AAD or ``District'') portion of the California State Implementation Plan (SIP). This revision governs the District's issuance of permits for stationary sources, and focuses on the preconstruction review and permitting of major sources and major modifications under part D of title I of the Clean Air Act (CAA or ``the Act''). We are taking comments on this proposal and plan to follow with a final action.

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Pinal County Air Quality Control District (PCAQCD) portion of the Arizona State Implementation Plan (SIP). These revisions concern the District's negative declarations for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or ``standards'') in the portion of the Phoenix-Mesa ozone nonattainment area under the jurisdiction of the PCAQCD and two volatile organic compound (VOC) rules covering gasoline dispensing and surface coating operations. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act). This approval stops all sanction and federal implementation plan clocks started by our August 9, 2019 partial and limited disapproval actions.\1\
