        <RULE_TITLE>NESHAP: Mercury Cell Chlor-Alkali Plants--Amendments</RULE_TITLE>
        <ABSTRACT><![CDATA[This action is a supplemental proposal for amendment of the national emission standards for hazardous air pollutants (NESHAP) for mercury emissions from mercury cell chlor-alkali plants that was promulgated in 2003. The 2003 NESHAP limited mercury air emissions from existing plants and prohibited the use of mercury in new plants. Following promulgation of the 2003 NESHAP, EPA received a petition to reconsider several aspects of the rule from the Natural Resources Defense Council (NRDC). NRDC also filed a petition for judicial review of the rule in the U.S. Court of Appeals for the D.C. Circuit. By a letter dated April 8, 2004, EPA granted NRDCs petition for reconsideration, and on July 20, 2004, the Court placed the petition for judicial review in abeyance pending EPAs action on the reconsideration. In May 2008, EPA proposed amendments in response to NRDCs petition for reconsideration. The 2008 amendments proposed changes to the regulation for cell room fugitive mercury emissions to require work practice standards for the cell rooms as well as to require instrumental monitoring of cell room fugitive mercury emissions. The 2008 proposed rule also amended aspects of the 2003 NESHAP to correct errors and inconsistencies that had been brought to EPA's attention since the NESHAP was promulgated. This supplemental proposal will add an additional control option to prohibit mercury emissions from existing plants that, in effect, requires conversion to an alternate chlorine production technology.]]></ABSTRACT>
