    Reading Time:about 77 minutes

    The Environmental Protection Agency (EPA) proposes partial approval and partial disapproval of Arizona's plan to meet the air quality standards for PM₁₀ in West Pinal County. This decision includes approving the emissions inventory for 2008 and disapproving several parts of the plan, including the measures for controlling pollution and the plan to reduce emissions over time. The EPA noted that Arizona's current strategies have not been sufficient to meet the required air quality standards and that some of the actions assumed in the plan have already been implemented too early to serve as backup measures if the state fails to meet its goals. Public comments are invited before the final decision is made.

    Simple Explanation

    The EPA is like a watchdog for clean air, and they found that Arizona's plan to keep the air clean in a town called West Pinal County isn't good enough, so they're saying yes to one small part and no to a lot of other parts of the plan. They want people to share their thoughts before they make a final decision.

  • 2021-03482 — Air Plan Limited Approval, Limited Disapproval; Arizona; Arizona Department of Environmental Quality
    Type:Proposed Rule
    Citation:86 FR 11681
    Reading Time:about 21 minutes

    The Environmental Protection Agency (EPA) is proposing a limited approval and limited disapproval of part of a plan submitted by the State of Arizona. This plan is designed to improve air quality by controlling particulate matter (PM) emissions from agricultural activities in certain parts of the state. The EPA recognizes that the proposed updates to Arizona's regulations could help reduce harmful PM emissions, but it also identified some deficiencies that don't fully meet federal standards. The EPA is considering approving the changes to add new control measures, while also initiating a process to address the unresolved issues.

    Simple Explanation

    The EPA is saying Arizona made a plan to keep the air cleaner by controlling dusty stuff from farms, but Arizona's plan needs a little more work to meet all the rules. So, the EPA likes some parts of the plan but thinks Arizona needs to fix a few things first.
