                                 A BILL


 
   To establish a national mercury monitoring program, and for other 
                               purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Comprehensive National Mercury 
Monitoring Act''.

SEC. 2. FINDINGS.

    Congress finds that--
            (1) mercury is a potent neurotoxin of significant 
        ecological and public health concern;
            (2) it is estimated that approximately 200,000 children 
        born each year in the United States are exposed to levels of 
        mercury in the womb that are high enough to impair neurological 
        development;
            (3) based on estimates from the Centers for Disease Control 
        and Prevention, between 2000 and 2010, between 2 and 6 percent 
        of women in the United States of childbearing age have exceeded 
        blood mercury levels determined to be safe by the Environmental 
        Protection Agency;
            (4) exposure to mercury occurs largely by the consumption 
        of contaminated fish, but fish and shellfish are important 
        sources of dietary protein and micronutrients, and a healthy 
        fishing resource is important to the economy of the United 
        States;
            (5) in many locations, the primary route for mercury input 
        to aquatic ecosystems is atmospheric emissions, transport, and 
        deposition;
            (6) existing broad-scale data sets are important but 
        insufficient to track changes in mercury levels in the 
        environment over time, test model predictions, and assess the 
        impact of changing mercury emissions and deposition; and
            (7) a comprehensive national mercury monitoring network to 
        accurately quantify regional and national changes in 
        atmospheric mercury deposition, ecosystem contamination, and 
        bioaccumulation of mercury in fish and wildlife in response to 
        changes in mercury emissions would help policy makers, 
        scientists, and the public to better understand the sources, 
        consequences, and trends of mercury pollution in the United 
        States.
