Portland Cement Plants: New Source Performance Standards (NSPS)

Rule Summary

New source performance standards (NSPS) implement Clean Air Act (CAA) section 111(b) and are issued for categories of sources which EPA has listed because they cause, or contribute significantly to, air pollution which may reasonably be anticipated to endanger public health or welfare. The primary purpose of the NSPS is to attain and maintain ambient air quality by ensuring that the best demonstrated emission control technologies are installed as industrial infrastructure is modernized. Since 1970, the NSPS have been successful in achieving long-term emissions reductions in numerous industries by assuring cost-effective controls are installed on new, reconstructed, or modified sources. 

Pollutants regulated under the Portland Cement NSPS are particulate matter, nitrogen oxide, and sulfur dioxide. Portland Cement is used worldwide as the main building block of infrastructure construction as well as for commercial and residential structures.
