To provide for the establishment of a national mercury monitoring program.

SECTION 1. SHORT TITLE.

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

SEC. 2. FINDINGS.

    Congress finds the following:
            (1) Mercury is a potent neurotoxin of significant 
        ecological and public health concern. Exposure to mercury 
        occurs largely by consumption of contaminated fish. Children 
        and women of childbearing age who consume large amounts of fish 
        are at high risk of adverse effects. It is estimated that 
        200,000 to 400,000 children born each year in the United States 
        have been exposed to mercury levels in their mothers' wombs 
        high enough to impair neurological development. The Centers for 
        Disease Control and Prevention have found that eight percent of 
        the women in the United States of childbearing age have blood 
        mercury levels in excess of values deemed safe by the 
        Environmental Protection Agency.
            (2) As of 2004, fish consumption advisories due to mercury 
        contamination have been issued for 44 States, including 21 
        statewide advisories for freshwaters and 12 statewide 
        advisories for coastal waters. These advisories represent more 
        than 52,000 square kilometers of lakes and 1,230,000 kilometers 
        of rivers. Yet, fish and shellfish are an important source of 
        dietary protein, and a healthy fishing resource is important to 
        the economy. The extent of fish consumption advisories 
        underscores the extensive human and ecological health risk 
        posed by mercury pollution.
            (3) In most locations, the primary route for mercury input 
        to aquatic ecosystems is by atmospheric transport and 
        deposition. Mercury's interaction with the environment and 
        bioaccumulation in biota are not fully understood. Computer 
        models and other assessment tools predict varying effectiveness 
        in reducing mercury concentrations in fish, and no broad-scale 
        data sets exist to test model predictions.
            (4) In September 2003, the Society of Environmental 
        Toxicology and Chemistry convened a workshop of 32 mercury 
        scientists to develop a system to measure and document changes 
        resulting from reductions in mercury emissions in the United 
        States. The resulting plan is documented in the book ``State of 
        Science for Mercury Effects: Assessment for Aquatic and 
        Terrestrial Environments'', published in 2007.
            (5) On January 1, 2005, ``Monitoring the Response to 
        Changing Mercury Deposition'' was published in the periodical 
        Environmental Science and Technology. The article proposed a 
        ``holistic, multimedia, long-term mercury monitoring program''.
            (6) Many regulations limiting mercury emissions have either 
        gone into effect or will soon be enacted, but scientists are 
        not adequately measuring the environmental benefits of reduced 
        mercury emissions. As governments advance regulations, 
        governments should document whether their rules are effective.
            (7) On May 15, 2006, the Office of Inspector General of the 
        Environmental Protection Agency issued a report entitled, 
        ``Monitoring Needed to Assess Impact of EPA's Clean Air Mercury 
        Rule (CAMR) on Potential Hotspots'', Report No. 2006-P-0025, 
        which states, in part: ``Without field data from an improved 
        monitoring network, EPA's ability to advance mercury science 
        will be limited and `utility-attributable' hotspots that pose 
        health risks may occur and go undetected'' and ``We recommend 
        that EPA develop and implement a mercury monitoring plan to (1) 
        assess the impact of CAMR, if adopted, on mercury deposition 
        and fish tissue; and (2) evaluate and refine mercury estimation 
        tools and models''.
            (8) On January 4, 2007, ``Contamination in Remote Forest 
        and Aquatic Ecosystems in the Northeastern U.S.: Sources, 
        Transformations and Management Options'' and ``Biological 
        Mercury Hotspots in the Northeastern U.S. and Southeastern 
        Canada'' were published in the journal BioScience. The authors 
        identified five biological mercury hotspots and nine areas of 
        concern in the northeastern United States and southeastern 
        Canada associated primarily with atmospheric mercury emissions 
        and deposition. They further located an area of particularly 
        high mercury deposition adjacent to a coal-fired electric 
        utility in southern New Hampshire. The authors of the studies 
        concluded that local impacts from mercury emissions should be 
        closely monitored in order to assess the impact of State and 
        Federal policies.

SEC. 7. DEFINITIONS.

    For purposes of this Act:
            (1) Ecoregion.--The term ``ecoregion'' means a large area 
        of land and water that contains a geographically distinct 
        assemblage of natural communities, including similar land 
        forms, climate, ecological processes, and vegetation.
            (2) Mercury export.--The term ``mercury export'' means 
        mercury flux from a watershed to the corresponding water body, 
        or from one water body to another (e.g. a lake to a river), 
        generally expressed as mass per unit time.
            (3) Mercury flux.--The term ``mercury flux'' means the rate 
        of transfer of mercury between ecosystem components (e.g. 
        between water and air), or between portions of ecosystem 
        components, expressed in terms of mass per unit time or mass 
        per unit area per time.
            (4) Surface sediment.--The term ``surface sediment'' means 
        sediment in the top 2 centimeters of a lakebed or riverbed.
