On July 13, 2017, a Consent Agreement and Final Order (CAFO) entered into by the U.S. Environmental Protection Agency, Region Ill ( EPA ) and Armstrong Cement and Supply Corporation ( Respondent'') was filed with the Regional Hearing Clerk settling a single alleged violation of the Clean Air Act ( 'CAA ). This CAFO initiated and resolved the single violation of the CAA alleged therein. The alleged violation occurred at the Respondent's cement manufacturing facility (the Facility) located at 100 Clearfield Road, Cabot, PA 16023. The Facility includes two kilns, including associated fine particulate matter control devices (PMCD), which are subject to regulations set forth at 40 CFR part 63, Subpart LLL (National Emission Standard for Hazardous Air Pollutants for Portland Cement Manufacturing Industry) ( Portland Cement NESHAP ). The alleged violation involved Respondent's failure to operate one or both kilns such that the temperature of the gas at the kiln PMCD, or at the ESP inlet, did not exceed the applicable temperature limit specified in 40 C.F.R. 63. I 346(b). The CAFO alleges that, based upon compliance reports submitted by Respondent, Respondent failed to ensure compliance with the applicable temperature limits intermittently on specified days during April 10, 2014 through June 24, 2014, July 8, 2014 through December 3, 2014 and June 4, 2015 through October 17, 2015.
