摘要

On September 21, 2017, the Environmental Protection Agency (EPA) proposed a rule titled, "National Emission Standards for Hazardous Air Pollutants From the Portland Cement Manufacturing Industry Residual Risk and Technology Review." The EPA is extending the comment period on the proposed rule that was scheduled to close on November 6, 2017, by 15 days until November 21, 2017. The EPA is making this change based on one request for additional time to prepare comments on this proposed rule.
