Existing plants, including the Clinchfield Cemex plant in Houston County — Georgia's only major cement plant — would face limits on their mercury emissions for the first time.
For plants that do not have any acid gas scrubbing systems and need to reduce SO 2 emissions, the GMCS can be configured as a very attractive alternative to a new wet or dry scrubber. GORE Mercury Control Systems have been tested and installed in numerous industrial non-power applications including incinerators, cement and metals plants.
More than seven years after a federal court ordered the U.S. Environmental Protection Agency (EPA) to regulate toxic mercury pollution from cement kilns, no action has been taken to curb these dangerous and rapidly growing emissions from over 150 plants located across the nation.

The Environmental Protection Agency has rated Lehigh Southwest Cement plant's mercury emissions as the second highest in the USA. The Lehigh Tehachapi plant produced 872lb of mercury in 2010, according to the Environmental Protection Agency's Toxics Release Inventory data – the most of any cement plant in California and the second highest among all cement plants in the United States.
In cement plants, the flue gas generally includes carbon dioxide (CO 2), nitrous oxides (NO x), sulfur dioxide (SO 2), mercury and dust. SO 2 emissions are mostly derived from the raw material, whereas the CO 2 emissions are related to the used fuel and efficiency of the combustion process.
The Lehigh Southwest Cement plant in Tehachapi emitted the most mercury of any cement plant in California in 2010. We know many of the major sources of mercury pollution in the US come from coal-fired power plants.
The Portland cement industry is currently the third-largest source of mercury emissions in the United States. The Lehigh Cement Plant plans to install several new emission control technologies to comply with the NESHAP amendments.
Cement plants had to meet an even harsher emission limit of 55 pounds per million tons of clinker averaged over 30 days. These plants typically have mercury emissions from both fuel burned and raw materials used to produce the cement clinker.
