The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Iowa State Implementation Plan (SIP) and the Operating Permit Program to incorporate recent changes to the Iowa Administrative Code (IAC). The revisions include removal of the Voluntary Operating Permit (VOP) Program language; removal of the Emission Reduction Program language; new and renumbered rules; replacement of duplicative language with references to state statute and federal regulations; updated definitions; consolidation of 14 chapters into 8 chapters; and minor clarifications to language and grammar. The EPA is also finalizing corrections to the erroneous incorporation of several rules into the Iowa SIP pursuant to the Clean Air Act (CAA). These revisions do not decrease the stringency of the SIP or have an adverse effect on air quality. The EPA's final approval of this rule revision is in accordance with the requirements of the CAA.
The U.S. Environmental Protection Agency (EPA or Agency) is approving the attainment plan and comprehensive emissions inventory for the Canton Nonattainment Area for the 2008 Lead (Pb) National Ambient Air Quality Standards (NAAQS) submitted by the Ohio Environmental Protection Agency (Ohio EPA or Ohio) on September 19, 2024.

The EPA is taking these actions in accordance with the Clean Air Act (CAA) and the Agency's implementation regulations regarding the 2008 Pb NAAQS. The EPA proposed these actions on March 27, 2026, with publication in the Federal Register on April 10, 2026, and we received no adverse comments.
