Pod Technologies – Portland Cement NESHAP

Updated: 06/27/2017

Overview

On August 9, 2010 the United States Environmental Protection Agency (US EPA) announced National Emission Standards for Hazardous Air Pollutants regulations for Portland Cement manufacturers (PC NESHAP). Also inculded in the proposed amendments were performance specifications for continuous emission monitors (CEMS) as well as updated recordkeeping and testing requirements:

On December 20, 2012 the US EPA finalized amendments to the agency's air toxics rules. The amended rule will maintain dramatic reductions of mercury, acid gases, particulate matter, and total hydrocarbons from existing cement kilns across the country, while ensuring that emissions from new kilns remain low:

On November 4, 2014 the US EPA proposed to amend the air toxics standards for new and existing cement kilns and new source performance standards for new kilns:

On July 1, 2015 the US EPA amended air toxics standards for new and existing cement kilns and new source performance standards for new kilns:

On July 14, 2016 the US EPA temporarily amended air toxics standards for new and existing cement kilns to assure that facilities can show compliance with hydrochloric acid (HCl) emissions limitations:

On June 19, 2017 the US EPA extended its approval for the use of an alternative method to show compliance with hydrogen chloride (HCl) emissions limits. This alternative will remain in place until calibration gases used to calibrate HCl continuous emissions monitoring systems at Portland cement plants are widely available. The action will allow the Portland cement industry to continue to demonstrate compliance with the rule:
