The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced that CalPortland Company (CPC), a major producer of Portland cement and building materials in the United States, has agreed to pay a $1.425 million penalty to resolve alleged violations of the Clean Air Act at its cement plant in Mojave, California. CPC will also spend an estimated $1.3 million on pollution controls that will reduce harmful emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2), pollutants that can lead to childhood asthma and smog.
The government�s complaint alleges that CPC made significant modifications to its plant, resulting in increased emissions of NOx, SO2 and carbon monoxide, without first obtaining a Clean Air Act-required permit and without installing necessary pollution control equipment. Major sources of air pollution are required to obtain such permits before making changes that would result in a significant emissions increase of any pollutant.
The settlement ensures that the proper equipment, estimated to cost $1.3 million to install and $500,000 per year to operate, will be installed to reduce future emission levels. These measures are expected to reduce pollution each year from the plant by at least 1,200 tons of NOx and 360 tons of sulfur dioxide SO2.
