EPA has signed a final rule setting revised national emissions standards for hazardous air pollutants (NESHAPs) and new source performance standards (NSPS) for the Portland cement manufacturing industry. EPA revised the emissions standards as the result of a settlement with the Sierra Club. Portland Cement Ass’n v. EPA, No. 07-1046 (D.C. Cir. 1/16/09). The rule sets emissions limits for mercury, total hydrocarbons and particulate matter for both major source cement kilns and smaller area source kilns. It also establishes emissions limits for hydrochloric acid for kilns that are major sources of the pollutant. The final rule will go into effect 60 days after it is published in the Federal Register.
