🌬️Indiana EPA Proposes Revisions for NOx Emissions Monitoring

The Environmental Protection Agency (EPA) is proposing to approve under the Clean Air Act (CAA) a request from the Indiana Department of Environmental Management (IDEM) to revise the Indiana State Implementation Plan (SIP) to incorporate revisions to nitrogen oxides (NO<INF>X</INF>) emissions monitoring, reporting and record keeping requirements for new and existing large non-Electric Generating Units (non-EGUs) affected by the NO<INF>X</INF> SIP Call. This SIP revision would approve monitoring, reporting, and record keeping requirements that are permissible as alternatives under Federal rules for these sources for purposes of the NO<INF>X</INF> SIP Call.

⚡Regulatory Relief for Coal-Fired Power Plants

This proclamation exempts certain stationary sources from stricter emissions standards for an additional two years, allowing them to adhere to earlier regulations. The decision emphasizes the importance of coal-fired electricity for national security and energy reliability, asserting that current emissions-control technologies are not yet commercially available.

♻️EPA Proposes New Emission Guidelines for Waste Combustors

The Environmental Protection Agency (EPA) is closing the reopened comment period on the proposed Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Large Municipal Waste Combustors Voluntary Remand Response and 5-Year Review. The original proposed rule was published on January 23, 2024, with a 60-day comment period closing March 25, 2024. This comment period was reopened on January 16, 2025, for an additional 6 months. The EPA is providing notice that the comment period for this rule will now close on May 30, 2025. We believe that a 6.5-month comment period in total is sufficient for interested stakeholders to submit comments and additional data.

🌍Proposed Air Quality Standards for Liberty-Clairton Area by EPA

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. This action does not redesignate the Allegheny County Area to attainment for the 2012 annual PM<INF>2.5</INF> NAAQS, as Pennsylvania withdrew its redesignation request specific to the Allegheny County Area. The redesignation request and maintenance plan were submitted by the Commonwealth of Pennsylvania Department of Environmental Protection (PADEP or Pennsylvania) on behalf of the Allegheny County Health Department (ACHD). This action is being taken under the CAA.
