| 2026-02843 | Approval and Promulgation of Air Quality Implementation Plans; Oklahoma; Regional Haze State Implementation Plan for the Second Implementation Period | Proposed Rule | The Environmental Protection Agency (EPA) is proposing to approve the regional haze state implementation plan (SIP) revision submitted by the State of Oklahoma on August 9, 2022 (Oklahoma's 2022 SIP submission), to satisfy applicable requirements under the Clean Air Act (CAA) and the EPA's Regional Haze Rule (RHR) for the program's second implementation (planning) period. Oklahoma's SIP submission addresses the requirement that states must periodically revise their long-term strategies for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. The SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program. The EPA is taking this action pursuant to the CAA. | 2026-02-12 | 2026 | 2 | https://www.federalregister.gov/documents/2026/02/12/2026-02843/approval-and-promulgation-of-air-quality-implementation-plans-oklahoma-regional-haze-state | https://www.govinfo.gov/content/pkg/FR-2026-02-12/pdf/2026-02843.pdf | Environmental Protection Agency | 145 | The Environmental Protection Agency (EPA) is proposing to approve the regional haze state implementation plan (SIP) revision submitted by the State of Oklahoma on August 9, 2022 (Oklahoma's 2022 SIP submission), to satisfy applicable requirements under... |
