US: The US Environmental Protection Agency (EPA) has issued a rule called 'National Emission Standards for Hazardous Air Pollutants for the Portland Cement Manufacturing Industry and Standards of Performance for Portland Cement Plants.'
The rule, published in the Federal Register on 12 February 2013 by Lisa P Jackson, US EPA Administrator, states, "On 18 July 2012 the EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants for the Portland Cement Manufacturing Industry and the Standards of Performance for Portland Cement Plants. This final action amends the national emission standards for hazardous air pollutants for the Portland cement industry."
"The EPA is also promulgating amendments with respect to issues on which it granted reconsideration on 17 May 2011. In addition, the EPA is amending the new source performance standard for particulate matter. These amendments promote flexibility, reduce costs, ease compliance and preserve health benefits."
"The amendments also address the remand of the national emission standards for hazardous air pollutants for the Portland cement industry by the United States Court of Appeals for the District of Columbia Circuit on 9 December 2011. Finally, the EPA is setting the date for compliance with the existing source national emission standards for hazardous air pollutants to be 9 September 2015."
