EPA is proposing to significantly reduce mercury emissions from Portland cement kilns, the fourth-largest source of mercury air emissions in the U.S. The proposal would set the nation’s first limits on mercury emissions from existing Portland cement kilns and would strengthen the limits for new kilns.
The proposed standards also would set emission limits for total hydrocarbons, particulate matter, and sulfur dioxide from cement kilns of all sizes, and would reduce hydrochloric acid emissions from kilns that are large emitters.
“We can save more than a thousand lives each year, sharply reduce mercury and other toxins in our air and water, and work with industry to encourage innovations and good ideas that are already out there,” said EPA Administrator Lisa P. Jackson. “Mercury and other chemicals flowing into these communities are health hazards for children, pregnant mothers, local residents and workers - people who deserve protection.”
