Air Emission Rules For Portland Cement Manufacturing

U.S. Environmental Protection Agency (EPA) is issuing final rules on emissions of mercury, particle matter and other pollutants from Portland cement manufacturing. Rules set the first limits on mercury air emissions from existing cement kilns, lowers the limits for new kilns, and sets emission limits on acid gases. This final rule also limits particle emissions from new and existing kilns, and sets new-kiln limits for particle and nitrogen oxides and sulfur dioxide.

When fully implemented in 2013, EPA estimates the annual emissions will be reduced:

•Mercury – 16,600 pounds or 92 %
•Total hydrocarbons – 10,600 tons or 83 %
•Particulate Matter – 11,500 tons or 92 percent
•Acid gases – 5,800 tons or 97 %
•Sulfur dioxide (SO2)– 110,000 tons or 78 %
•Nitrogen oxides (NOx) – 6,600 tons or 5 %
