  • 2025-04035 — Extension of the Attainment Date of the Coachella Valley Extreme Nonattainment Area Under the 1997 Ozone National Ambient Air Quality Standards
    Type:Proposed Rule
    Citation:90 FR 12239
    Reading Time:about 25 minutes

    The Environmental Protection Agency (EPA) is proposing to give the Coachella Valley in Riverside County, California, one more year to meet the air quality standards for ozone that were set in 1997. This proposal is based on a thorough evaluation of the air quality data and a request from the State of California. If accepted, this would extend the deadline from June 2024 to June 2025. The public is invited to comment on this proposal, especially concerning the exceptional events like wildfires, which affected the air quality data.

    Simple Explanation

    The EPA wants to give Coachella Valley in California one more year, until June 2025, to clean up its air and meet older ozone pollution rules because wildfires made the air worse. They are asking people to share their thoughts on this idea.

  • 2021-02536 — Air Plan Approval; Massachusetts; Infrastructure State Implementation Plan Requirements for the 2015 Ozone Standard
    Type:Rule
    Citation:86 FR 8693
    Reading Time:about 16 minutes

    The Environmental Protection Agency (EPA) approved Massachusetts' State Implementation Plan (SIP) submission, which meets most infrastructure requirements for the 2015 ozone National Ambient Air Quality Standards (NAAQS) under the Clean Air Act. However, EPA issued a finding of failure for certain parts related to the prevention of significant deterioration (PSD) program requirements. Despite this, the finding will not lead to sanctions or new federal requirements, as Massachusetts is already under a Federal Implementation Plan for PSD. The decision was based on Massachusetts demonstrating they have adequate resources and authority for SIP enforcement, even considering potential impacts from the COVID-19 pandemic.

    Simple Explanation

    The EPA said that Massachusetts can mostly follow the rules to keep the air clean, but they need a bit more work on a special plan to stop pollution from getting worse. Don't worry, though—this won't cause any big problems because there's already a backup plan in place.

  • 2021-02556 — Air Plan Approval; Pennsylvania; 1997 8-Hour Ozone National Ambient Air Quality Standard Second Maintenance Plan for the Harrisburg-Lebanon-Carlisle Area
    Type:Rule
    Citation:86 FR 8689
    Reading Time:about 9 minutes

    The Environmental Protection Agency (EPA) has approved a revision to Pennsylvania's State Implementation Plan (SIP) for maintaining air quality standards for ozone in the Harrisburg-Lebanon-Carlisle area. This revision helps ensure the area continues to meet the 1997 8-hour ozone standards through 2027. The EPA found that Pennsylvania's submission satisfied legal requirements, even after discovering a minor computational error in emission data that did not affect the decision. This approval makes certain air quality maintenance commitments enforceable under federal law.

    Simple Explanation

    The EPA said yes to Pennsylvania's plan to keep the air clean and healthy in some cities by sticking to rules about ozone, which is a type of pollution. This means Pennsylvania promised to make sure the air stays good to breathe, and now the EPA is helping to make this a rule everyone has to follow.

  • 2021-04065 — Air Plan Approval; North Carolina: Revisions to Annual Emissions Reporting
    Type:Rule
    Citation:86 FR 11867
    Reading Time:about 14 minutes

    The Environmental Protection Agency (EPA) approved changes to North Carolina's State Implementation Plan (SIP) submitted on July 10, 2019. This approval removes the need for certain facilities to report annual emissions in areas now meeting older ozone standards but keeps the reporting requirement in place for the 2008 ozone standards. The adjustments update the start year for emissions reporting and make minor edits to the regulation. EPA's decision is based on these changes meeting the requirements of the Clean Air Act.

    Simple Explanation

    The EPA decided it's okay for some places in North Carolina to stop counting how much pollution they make each year since they are now cleaner, but they still need to keep counting if they have to follow newer rules from 2008.

  • 2021-03278 — Approval and Promulgation of Implementation Plans; Colorado; Revisions to Regulation Number 7 and RACT Requirements for 2008 8-Hour Ozone Standard for the Denver Metro/North Front Range Nonattainment Area
    Type:Rule
    Citation:86 FR 11125
    Reading Time:about 10 minutes

    The Environmental Protection Agency (EPA) is approving changes to Colorado's State Implementation Plan (SIP) concerning air quality control, specifically targeting ozone levels in certain areas. This involves updates to Regulation Number 7 for better management of emissions like volatile organic compounds (VOCs) and nitrogen oxides (NOx) following the 2008 ozone standards. The action also corrects an oversight from a 2018 rule. This decision is made under the Clean Air Act and does not impose any extra requirements beyond those set by state law.

    Simple Explanation

    The EPA is helping Colorado clean up its air by changing some rules to reduce certain gases that make the air dirty, so people can breathe better. They are also fixing an old mistake in the rules to make sure everything is right.

  • 2025-01110 — Approval and Promulgation of Implementation Plans; State of California; Coachella Valley; Extreme Attainment Plan for 1997 8-Hour Ozone Standards
    Type:Rule
    Citation:90 FR 6823
    Reading Time:about 28 minutes

    The Environmental Protection Agency (EPA) has approved parts of California's plan to meet air quality standards in the Coachella Valley for ozone levels set in 1997. They approved demonstrations showing reasonable progress and efforts to offset vehicle emissions. The decision follows public comments and reviews of the plan, confirming the approach is scientifically valid and doesn't delay attainment of air quality goals. The action is consistent with the Clean Air Act and doesn't add new requirements beyond those already established by California law.

    Simple Explanation

    The EPA is happy with how California is trying to make the air cleaner in the Coachella Valley by reducing smog, especially from cars, and says they are doing a good job following the rules from a while ago.
