MoreCement kilns, as previously reported, will have to control
mercury after the EPA on Thursday, Sept. 9, 2010, published its finalized
amendments to the National Emission Standards for Hazardous Air Pollutants
(NESHAP) from the Portland Cement Manufacturing Industry and to the New Source
Performance Standards (NSPS) for Portland Cement Plants in the Federal
Register.
The final amendments to the NESHAP add or revise, as applicable, emission limits for mercury, total hydrocarbons (THC), and particulate matter from new and existing kilns located at major and area sources, and for hydrochloric acid (HCl) from new and existing kilns located at major sources. The standards for new kilns apply to facilities that commence construction, modification, or reconstruction after May 6, 2009.
The final amendments to the NSPS add or revise, as applicable, emission limits for PM, opacity, NOX, and SO2 for facilities that commence construction, modification, or reconstruction after June 16, 2008. The final rule also includes additional testing and monitoring requirements for affected sources.
The agency first proposed these standards on June 16, 2008. According to the EPA, 46 comments were received from the Portland cement industry, environmental groups, State environmental agencies and others during the comment period.
The major difference in the new standards is the MACT controls on mercury. The controls will be as follows for each kiln code, as displayed in million pounds clinker.
