Mercury Regulation

According to the Environmental Protection Agency (EPA), power plants in the U.S. emit nearly 50 tons of mercury per year. In an effort to reduce mercury emissions from coal-fired power plants, the EPA has issued stringent mercury emissions standards. The EPA's Maximum Achievable Control Technology (MACT) standards and new Mercury and Air Toxic Standards (MATS) apply to every coal-fired power plant in the country, including the concrete industry and industrial power plants, as well as utilities. The EPA has established an aggressive timeline for compliance with the federal standards:

• Utility MATS: April 16, 2015

• Portland Cement MACT: September 9, 2015

• Industrial Boiler MACT 
    Compliance deadlines for major boilers and CISWI units will be in 2016 and 2018, respectively.    
        
In addition, over 20 states have enacted regulations that cap mercury emissions from coal-fired boilers, as has the Canadian government.

Amended Silicates, a non-carbon reagent, provides an effective, environmentally friendly and economically responsible method for complying with mercury emissions regulations. In extensive field trials, Amended Silicates exceeded the mercury removal rates required by EPA at a cost that is competitive with Activated Carbon Injection (ACI).
