                                 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 410,000 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) the Centers for Disease Control and Prevention have 
        found that 6 percent of women in the United States of 
        childbearing age have blood mercury levels in excess of values 
        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 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 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 in United States mercury pollution.

                and fish and wildlife in terrestrial, freshwater, 
                coastal, and marine ecosystems in response to changing 
                mercury emissions over time.
            (3) Monitoring sites.--
                    (A) In general.--In carrying out paragraph (1), not

                emissions.
                    (C) Colocation.--Monitoring sites shall be 
                colocated with sites from other long-term environmental 
                monitoring programs, where practicable, including sites 
                associated with the National Ecological Observatory 
                Network, the Long-Term Ecological Research Network, and

        year after the date of enactment of this Act, the 
        Administrator, in coordination with the Advisory Committee, 
        shall establish a centralized database for existing and newly 
        collected environmental mercury data that can be freely 
        accessed on the Internet once data assurance and quality 
        standards established by the Administrator are met.
    (b) Functions.--
            (1) In general.--Under the program, the Administrator, in 
        consultation with the appropriate Federal agencies and the
