摘要

The Environmental Protection Agency would require Portland cement kiln operators to significantly reduce emissions of mercury and other air toxics in a proposed rule published in the Federal Register May 6 (74 Fed. Reg. 21,136). The proposed rule would establish new national emissions standards for hazardous air pollutants for cement kilns under 40 C.F.R. Part 63. By the time the standards are fully implemented in 2013, annual mercury emissions would be reduced by 11,600 tons, an 81 percent cut, according to the proposed rule. The proposed rule would also require reductions in other emissions from cement kilns. Emissions of total hydrocarbons would be reduced by 11,700 tons, or 75 percent, EPA said, while particulate matter emissions would fall by 10,500 tons, or 96 percent. The proposal would reduce emissions of hydrochloric acid by 2,800 tons, or 94 percent, and emissions of sulfur dioxide by 160,000 tons, or 90 percent. EPA released the proposal informally April 21 (40 ER 901, 4/24/09).
