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.

How can I get copies of the proposed amendments and other related 
information?

    EPA has established the official public docket for the proposed 
rulemaking under docket ID No. EPA-HQ-OAR-2002-0051. Information on how
