    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.
