Reopening of Comment Period

On December 2, 2005, EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants From the Portland Cement Manufacturing Industry. (70 FR 72330). Among other things, we there proposed to amend the emission standards for mercury, hydrogen chloride, and total hydrocarbons.

In response to a request to reopen the comment period to address these proposed standards, EPA is reopening the comment period for a period of two weeks. This solicitation is limited to the standards for mercury, hydrogen chloride, and total hydrocarbons.
