Dear Sirs Mt Carmel Cogen 10343 wishes to request a Presidential Exemption for the Ruling of "National Emission Standards for Hazardous Air Pollutants: Coal and Oil Fired Electric Utility Steam Generating Units Review of the Residual Risk and Technology Review" (89 FR 38508; May 7, 2024) (MATS Rule) The EPA requirement of fPM emission control reduction to 0.010 lb/MMBtu would be below practical operating standards of the current equipment at the Mt Carmel Cogeneration facility, located in Marion Heights Pa. For this standard to be met, a complete process filter arrangement would need to be updated and implemented. The process of engineering, changeout and testing may take up to 2 years. In addition, PM CEMS would need to installed to demonstrate compliance for the final rule. For these reasons, Mt Carmel Cogen is requesting a 2 year extension to implement equipment, software and testing to comply with the new regulations. Any questions or comments can be addressed to myself. Thank you Jack Yanchak Environmental Manager Mt Carmel Cogen Inc Sierra Club FOIA 2025-EPA-04883 ED_018388_00005504-00001 SC_EVERSPLIT0020490 570 373 3999 ex 4 Sierra Club FOIA 2025-EPA-04883 ED_018388_00005504-00002 SC_EVERSPLIT0020491
