The EPA has announced that emissions from Portland cement and container glass plants will be reduced under the settlement of a New Source Review case. The settlement requires the affected facilities to install new pollution control equipment Selective Catalytic Reduction, and to continuously monitor their emissions.

 

The settlements cover 15 U.S. plants owned by Saint-Gobain Containers, Inc., the nation's second largest container glass manufacturer, and all 13 U.S. plants owned by the Lafarge Company and two subsidiaries, the nation?EUR??,,????'?????<

These settlements are the first system-wide settlements for these sectors under the Clean Air Act and require pollution control upgrades, acceptance of enforceable emission limits and payment of civil penalties.

The facilities are estimated to reduce a combined 41,000 tons of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM) each year. SO2, NOx, and PM can trigger respiratory difficulties and asthma, and environmental impacts such as acid rain, visibility impairments, and water quality impacts.

Lafarge North America, Inc., based in Herndon, Va., and two of its subsidiaries have agreed in a consent decree filed in federal court in Benton, Ill., to install and implement control technologies at an expected cost of up to $170 million to reduce emissions of NOx by more than 9,000 tons each year and SO2 by more than 26,000 tons per year at their cement plants.

Lafarge has agreed to install the first-ever SCR system at a cement plant in the United States. In addition, Lafarge has also agreed to install seven selective non-catalytic reduction (SNCR) systems at long dry cement kilns. This is among the first application of this technology to this type of kiln in the United States. Lafarge will also install CEMS at all of their cement kilns.
