"EPA Targets Cement industry Emissions"

"Environmentalists and industry representatives pleaded their case with federal regulators Tuesday over rules that would slash toxic emissions from cement kilns, the top source of mercury emissions in California.

The Environmental Protection Agency issued proposed regulations for Portland cement kilns earlier this year, after more than a decade of pressure from environmental groups. The rules aim to reduce the industry's mercury emissions by an estimated 81% to 93% annually, as well as cut emissions of hydrocarbons, particulate matter and hydrochloric acid."
