Missing Mercury in Manufacturing Monitoring and Mitigation Act

Missing Mercury in Manufacturing Monitoring and Mitigation Act - Declares that the United States should develop policies and programs that will reduce: (1) mercury use and emissions; (2) mercury releases from the reservoir of mercury currently in use or circulation; and (3) exposures to mercury, particularly of women of childbearing age and young children.

Amends the Toxic Substances Control Act to prohibit the manufacture of chlorine or caustic soda using mercury cells, effective January 1, 2012. Requires the owner or operator of each chlor-alkali facility to submit to the Environmental Protection Agency (EPA) Administrator and the state in which the facility is located an annual report for 2009-2012 concerning mercury waste, emissions, and content in products.

Requires the Administrator to : (1) conduct a comprehensive mercury inventory covering the life and closure of chlor-alkali facilities that cease operations on or after January 1, 2009; and (2) obtain mercury purchase records and such other information from each such facility as are necessary to determine the magnitude and nature of mercury releases from the facility into air and other environmental media.
