    The Environmental Protection Agency (EPA) has issued a final decision to partially approve and partially disapprove Utah's plan to address regional haze, which affects air quality in national parks and wilderness areas. The EPA found Utah's plan partially insufficient as it failed to meet certain requirements, such as implementing stronger controls on emissions from specific power plants. Additionally, the EPA disapproved parts of Utah's plan addressing visibility pollution related to ozone levels from a 2020 submission. This ruling emphasizes the need for stronger measures to protect visibility and air quality in protected areas.

    Simple Explanation

    The EPA is like a referee for clean air, and they looked at Utah’s plan to keep the air clear in parks. They said some parts of Utah’s plan are good, but some parts need to be better, like stopping smoke from big factories so everyone can enjoy nice, clean air.

  • 2021-02894 — Approval and Promulgation of Air Quality Implementation Plans; Louisiana; Infrastructure State Implementation Plan Requirements for the National Ambient Air Quality Standards
    Type:Proposed Rule
    Citation:86 FR 10509
    Reading Time:about 13 minutes

    The Environmental Protection Agency (EPA) has proposed to approve a State Implementation Plan (SIP) from Louisiana that aims to meet the air quality standards set by the Clean Air Act. Submitted on November 4, 2020, the plan addresses requirements to reduce emissions that affect visibility and pollution in neighboring states, fulfilling a previous shortcoming related to Prong 4, which involves visibility transport rules. With the approval of Louisiana's regional haze plan, the EPA believes the state now satisfies the necessary provisions for various pollutants, including ozone, nitrogen dioxide, sulfur dioxide, and particulate matter (PM2.5). The plan ensures that Louisiana's measures align with federal air quality standards and do not interfere with the air quality efforts of other states.

    Simple Explanation

    The EPA wants to give a thumbs up to a plan from Louisiana that promises to keep the air clean and make sure smoke and pollution don't bother other nearby states. This plan shows how Louisiana will work with others to follow the rules for clean air and not make the air dirty.
