| 2020-23994 | Approval and Promulgation of Air Quality Implementation Plans; Utah; Regional Haze State and Federal Implementation Plans | Rule | The Environmental Protection Agency (EPA) is finalizing approval of State Implementation Plan (SIP) revisions submitted by the State of Utah on July 3, 2019, as supplemented on December 3, 2019, to satisfy certain regional haze requirements for the regional haze program's first implementation period (Utah SIP revisions). The EPA is approving the Utah SIP revision that provides an alternative to best available retrofit technology (BART) controls for nitrogen oxides (NO<INF>X</INF>) at the PacifiCorp Hunter and Huntington power plants. The EPA finds that the NO<INF>X</INF> BART Alternative for Hunter and Huntington achieves greater reasonable progress toward natural visibility conditions than BART, in accordance with the requirements of the Clean Air Act (CAA) and the EPA's Regional Haze Rule. In conjunction with this approval, we are withdrawing the Federal Implementation Plan (FIP) that addresses NO<INF>X</INF> BART for the Hunter and Huntington power plants that EPA promulgated in 2016. The EPA is also approving Utah's December 3, 2019 SIP supplement that requires reporting of all deviations from compliance with the applicable requirements under particulate matter (PM) BART and the NO<INF>X</INF> BART Alternative, including the emission limits for Hunter and Huntington. The EPA is taking these actions pursuant to sections 110 and 169A of the CAA. | 2020-11-27 | 2020 | 11 | https://www.federalregister.gov/documents/2020/11/27/2020-23994/approval-and-promulgation-of-air-quality-implementation-plans-utah-regional-haze-state-and-federal | https://www.govinfo.gov/content/pkg/FR-2020-11-27/pdf/2020-23994.pdf | Environmental Protection Agency | 145 | The Environmental Protection Agency (EPA) is finalizing approval of State Implementation Plan (SIP) revisions submitted by the State of Utah on July 3, 2019, as supplemented on December 3, 2019, to satisfy certain regional haze requirements for the... |
