Air Plan Approval; Ohio; Ohio NSR Permit Timing
The Environmental Protection Agency (EPA) is re-opening the comment period for a proposed rule published February 11, 2021. On February 11, 2021, EPA proposed to approve, under the Clean Air Act, an Ohio rule that would allow for the extension of an installation permit which is the subject of an appeal by a party other than the owner or operator of the air contaminant source. In response to requests from members of the public, EPA is re-opening the comment period for an additional 30 days.
Approval and Promulgation of State Plans for Designated Facilities and Pollutants; South Dakota; Control of Emissions From Existing Municipal Solid Waste Landfills
The Environmental Protection Agency (EPA) is approving a Clean Air Act (CAA or the ``Act'') section 111(d) state plan submitted by the South Dakota Department of Environment and Natural Resources (DENR or the ``Department'') on January 3, 2020. This plan was submitted to fulfill the requirements of the CAA and is responsive to the EPA's promulgation of Emission Guidelines and Compliance Times (EG) for existing municipal solid waste (MSW) landfills. The South Dakota state plan establishes performance standards and operating requirements for existing MSW landfills within the State of South Dakota and provides for the implementation and enforcement of those standards and requirements by the Department. The EPA is taking this action pursuant to requirements of the CAA.
Air Plan Approval; Texas; Interstate Visibility Transport
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is disapproving elements of two State Implementation Plan (SIP) submissions from the State of Texas for the 2012 PM2.5 National Ambient Air Quality Standard (NAAQS) and the 2015 Ozone NAAQS. These submittals address how the existing SIP provides for implementation, maintenance, and enforcement of the 2012 PM2.5 and 2015 Ozone NAAQS (infrastructure SIP or i-SIP). The i-SIP requirements are to ensure that the Texas SIP is adequate to meet the state's responsibilities under the CAA for these NAAQS. Specifically, this disapproval addresses the interstate visibility transport requirements of the i-SIP for the 2012 PM2.5 and 2015 Ozone NAAQS under CAA section 110(a)(2)(D)(i)(II). In addition to this disapproval, we are finalizing our determination that the requirements of those i-SIP elements are met through the Federal Implementation Plans (FIPs) in place for the Texas Regional Haze program, and no further federal action is required.
Partial Approval and Partial Disapproval of Air Quality State Implementation Plans; California; Infrastructure Requirements for Ozone
The Environmental Protection Agency (EPA) is taking final action to partially approve and partially disapprove the state implementation plan (SIP) revisions submitted by the State of California pursuant to the requirements of the Clean Air Act (CAA or ``Act'') for the implementation, maintenance, and enforcement of the 2015 national ambient air quality standards (NAAQS or ``standards'') for ozone. Specifically, the EPA is approving the SIP revision for all elements except those that relate to prevention of significant deterioration (PSD). EPA is partially approving and partially disapproving three elements of the SIP revision due to PSD deficiencies in certain air pollution control or air quality management districts (APCD, AQMD, or ``district''). The disapprovals will not create any new consequences for these districts or the EPA as the districts are already subject to the EPA's federal PSD program at 40 CFR 52.21. As part of this action, we are also reclassifying certain regions of the State for emergency episode planning purposes with respect to ozone. We are also approving into the SIP two updated state provisions addressing CAA conflict of interest requirements for the entire state, and emergency episode plans for the Amador County APCD, Calaveras County APCD, Mariposa County APCD, Northern Sierra AQMD, and Tuolumne County APCD. Finally, we are approving an exemption from emergency episode planning requirements for ozone for the Lake County AQMD.
