The Environmental Protection Agency (EPA) is finalizing the limited approval and limited disapproval of a revision to the Yolo- Solano Air Quality Management District (YSAQMD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of volatile organic compounds (VOCs) from solvent cleaning and degreasing operations. Under the authority of the Clean Air Act (CAA or the Act), this action simultaneously approves a local rule that regulates these emission sources and directs California to correct rule deficiencies.

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Missouri on November 12, 2019, revising the 2008 8-hour ozone maintenance plan previously approved by EPA on September 20, 2018, demonstrating continued maintenance of the 2008 ozone National Ambient Air Quality Standard (NAAQS), the 1979 1-Hour and 1997 8-Hour ozone standards in the St. Louis area. This revision states that the St. Louis area no longer needs to rely on the Inspection and Maintenance (I/M) program, and Reformulated Gasoline (RFG) for continued maintenance throughout the maintenance period for the 2008 8-Hour ozone NAAQS, the 1979 1-Hour ozone NAAQS and 1997 8-Hour ozone NAAQS. EPA is proposing to determine that this revision meets the requirements of the Clean Air Act.
