  • 2021-02616 — Air Plan Approval; West Virginia; 2020 Amendments to West Virginia's Ambient Air Quality Standards
    Type:Proposed Rule
    Citation:86 FR 8727
    Reading Time:about 6 minutes

    The Environmental Protection Agency (EPA) is proposing to approve revisions to West Virginia's state implementation plan (SIP), which updates the state's incorporation of the EPA's National Ambient Air Quality Standards (NAAQS) and related monitoring methods. These changes span updates made between June 2018 and June 2019, including new reference methods for measuring air pollutants like sulfur oxides, ozone, nitrogen dioxide, and carbon monoxide. This proposal is made under the Clean Air Act, and the EPA is inviting public comment on this update, although they are not seeking input on the specific levels of NAAQS already established in prior proposals.

    Simple Explanation

    The EPA wants to let West Virginia use updated rules for checking air pollution, like measuring dust and smoke, to keep the air clean. This change is under a big law that helps make sure everyone breathes in good air.

  • 2021-02624 — Air Plan Approval; Pennsylvania; 1997 8-Hour Ozone National Ambient Air Quality Standard Second Maintenance Plan for the Erie Area

    Citation:86 FR 8722
    Reading Time:about 22 minutes

    The Environmental Protection Agency (EPA) is proposing to approve a plan from Pennsylvania to maintain air quality standards for ozone in Erie County. This plan ensures Erie County stays within the safe limits for ozone levels specified by the 1997 standards for an additional 10 years, up until 2027. The EPA is open to public comments on this proposal until March 11, 2021. The plan includes measures such as emissions inventories, maintaining air quality monitoring, and a commitment to take action if ozone levels rise.

    Simple Explanation

    The EPA wants to make sure the air stays clean in Erie County, Pennsylvania, so they are checking a plan from Pennsylvania that promises to keep ozone levels safe until 2027. They will listen to what people think about this plan until March 11, 2021.

  • 2025-04791 — Determination of Attainment by the Attainment Date; 2008 8-Hour Ozone Standards; California; Sacramento Metro Area
    Type:Proposed Rule
    Citation:90 FR 13316
    Reading Time:about 25 minutes

    The Environmental Protection Agency (EPA) is suggesting that the Sacramento Metro area in California has met the ozone air quality standards set in 2008 by the deadline of December 31, 2024. This decision is based on air quality data collected from 2022 to 2024. If this proposal is finalized, certain air quality contingency measures that were required in case of air quality standard violations would no longer be necessary. The EPA is currently seeking public comments on this proposal until April 21, 2025, before making a final decision.

    Simple Explanation

    The EPA is suggesting that the air in Sacramento, California, has become cleaner and meets the safety standards for ozone levels by the end of 2024. This means if everything checks out, they won't need extra plans just in case the air gets bad again.

  • 2024-29223 — Reconsideration of the National Ambient Air Quality Standards for Particulate Matter; Correction
    💰
    Type:Rule
    Citation:89 FR 103652
    Reading Time:about 19 minutes

    The Environmental Protection Agency (EPA) issued a correction for a previously published rule regarding air quality standards for particulate matter, particularly focusing on PM2.5 standards. The final rule, originally published in March 2024, had errors in its text about deadlines for state plans and technical descriptions for air quality monitors. The EPA clarified that states must submit implementation plans within three years of the standards' announcement, not their effective date. Additionally, several technical corrections were made, such as updating measurement methods and fixing typographical errors, all of which don't change the rule's substance.

    Simple Explanation

    The EPA fixed mistakes in its rules about air quality and explained that states need to make plans to help clean the air within three years of the new rules being announced. They also fixed some small errors about how air quality is measured, without changing the main rules.
