Mr. President, today along with Senator Carper, I am introducing the Comprehensive National Mercury Monitoring Act. This bill would ensure that we have accurate information about the extent of mercury pollution in the United States.
A comprehensive national mercury monitoring network is needed to protect human health, safeguard fisheries, and track the effect of emissions reductions. This tracking is particularly important in light of increasing mercury emissions from other countries, including a substantial amount of mercury emissions from China. Mercury can be transported around the globe, meaning emissions and releases can affect human health and environment even in remote locations.
The issue of mercury emissions is growing in importance around the world. In 2013, the United States was the first Nation to join and sign the Minamata Convention on Mercury, a global agreement to reduce mercury pollution. The Minamata Convention has been signed by more than 125 countries and raises the issue that mercury poses a global threat to human health. At present, scientists must rely on limited information to understand the critical linkages between mercury emissions and environmental response and human health. Successful design, implementation, and assessment of solutions to the mercury pollution problem require comprehensive long-term information. A system for collecting such information, such as we have for acid rain and other pollution, does not currently exist for mercury--a much more toxic pollutant.
Mercury is a potent neurotoxin of significant ecological and public health concern, especially for children and pregnant women. It is estimated that approximately 200,000 children born in the U.S. per year are exposed to levels of mercury in the womb that are high enough to impair neurological development. Mercury exposure has gone down as U.S. mercury emissions have declined; however, levels remain far too high.
By accurately quantifying regional and national changes in atmospheric deposition, ecosystem contamination, and bioaccumulation of mercury in fish and wildlife in response to changes in mercury emissions, a monitoring network would help policy makers, scientists, and the public to better understand the sources, consequences, and trends in mercury pollution in the United States. We must have more comprehensive information and we must have it soon; otherwise, we risk making misguided policy decisions.
Specifically, the Comprehensive National Mercury Monitoring Act would:
Direct EPA, in conjunction with the Fish and Wildlife Service, U.S. Geological Survey, National Park Service, the National Oceanic and Atmospheric Association, and other appropriate Federal agencies, to establish a national mercury monitoring program to measure and monitor mercury levels in the air and watersheds, water and soil chemistry, and in marine, freshwater, and terrestrial organisms across the nation;
Establish a scientific advisory committee to advise on the establishment, site selection, measurement, recording protocols, and operations of the monitoring program;
Establish a centralized database for existing and newly collected environmental mercury data that can be freely accessed on the Internet and is comprised of data that is compatible with similar international efforts;
Require a report to Congress every two years on the program, including trends, and an assessment of the reduction in mercury deposition rates that need to be achieved in order to prevent adverse human and ecological effects every four-years; and
Authorize $95 million over three years to carry out the Act.
We must establish a comprehensive, robust national monitoring network
for mercury to provide the data needed to help make decisions to protect the people and environment of Maine and the United States.
