The Environmental Protection Agency (EPA) is approving a September 28, 2023, State Implementation Plan (SIP) submittal from the Ohio Environmental Protection Agency (Ohio EPA).

The source-specific limitation reflects the technological differences between the facility's new control unit and cold cleaner requirements currently established in Ohio's SIP. Ohio EPA has determined that the source-specific VOC limitation for the cold cleaner is more stringent than existing cold cleaner limits in the Ohio SIP. EPA proposed to approve this action on October 7, 2024, and received no adverse comments.

The Environmental Protection Agency (EPA) is proposing to approve a request from the Commonwealth of Pennsylvania to redesignate the Liberty-Clairton, Pennsylvania nonattainment area (Liberty-Clairton Area) to attainment for the 1997 annual and 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or standard). The EPA is also proposing to approve, as revisions to the Pennsylvania state implementation plan (SIP), the Commonwealth's plan for maintaining the 1997 annual and 2006 24-hour PM<INF>2.5</INF> NAAQS through 2035 for the Liberty-Clairton Area. Additionally, the EPA is proposing to approve the maintenance plan for the Allegheny County, Pennsylvania nonattainment area (Allegheny County Area) for the 2012 annual PM<INF>2.5</INF> NAAQS through 2035. The maintenance plan includes 2017, 2026, and 2035 mobile vehicle emissions budgets (MVEBs) for mobile sources of PM<INF>2.5</INF> and nitrogen oxides (NO<INF>X</INF>) for the Allegheny County Area. The EPA is proposing to find these 2017, 2026, and 2035 MVEBs for PM<INF>2.5</INF> and NO<INF>X</INF> adequate and to approve these MVEBs into the Pennsylvania SIP for transportation conformity purposes.
