🌱EPA Proposes New Air Quality Regulations for Arizona Agriculture
The Environmental Protection Agency (EPA) is proposing an approval and a limited approval and limited disapproval of a State Implementation Plan (SIP) submission made by the State of Arizona to address emissions of particulate matter 10 micrometers in diameter or smaller (PM<INF>10</INF>) from agricultural operations. The SIP submission includes an amended statute, two definition rules, and two rules regulating crop and animal operations in Pinal County, Arizona. We are proposing action on local rules to regulate these emission sources under the Clean Air Act (CAA or "Act"). We are taking comments on this proposal and plan to follow with a final action.

Due to the receipt of adverse comment, the Environmental Protection Agency (EPA) is withdrawing the November 26, 2024, direct final rule to partially withdraw two final actions finding that 13 States and/or local air pollution control agencies failed to submit State Implementation Plan (SIP) revisions required by the Clean Air Act (CAA) in a timely manner to address the EPA's 2015 findings of substantial inadequacy and "SIP calls" for provisions applying to excess emissions during periods of startup, shutdown, and malfunction (SSM). The EPA will address all comments received in a subsequent final rule for which the EPA will not institute a second comment period.
