New Report to Reveal 25 Worst Mercury Polluters of the Great Lakes

NRDC Report to Highlight Great Lakes Polluting Coal-Fired Power Plants in IL, IN, MI, MN, NY, OH, PA and WI; New EPA Standards That Will Protect Great Lakes are Under Attack


Just ahead of a major U.S. Senate vote on the Environmental Protection Administration's authority to clean up mercury and other toxic air pollutants, a Natural Resources Defense Council (NRDC) report shows that the 25 worst coal-fired power plants account for more than half of the dangerous mercury pollution emitted by the total of 144 electricity generation facilities in the Great Lakes region. The report also finds that almost 90 percent of the toxic emissions could be eliminated with off-the-shelf technologies.

According to "Poisoning the Great Lakes: Mercury Emissions from Coal-Fired Power Plants In the Great Lakes Region," Ohio emits the largest amount of mercury from coal-fired power plants (21 percent of the total in the Great Lakes region), followed closely by Pennsylvania (20 percent) and Indiana (16 percent). The remaining five states in the region rank as follows: Michigan (14 percent); Illinois (11 percent); Wisconsin (9.5 percent); Minnesota (6.5 percent); and New York (2 percent). Plants from outside the region also contribute to mercury pollution in the Great Lakes.

"Mercury is a dangerous brain poison that doesn't belong in our Great Lakes," said Thom Cmar, attorney in , Natural Resources Defense Council office in Chicago, said:

It puts the health of kids and pregnant women at risk and adds an unwelcome danger to eating what our fishermen catch. That's why it is so important that we support the EPA's standards to reduce mercury pollution by holding polluters accountable. Even more critical is that every single US Senator from the region stand up for the Lakes by rejecting reckless attempts to derail the long overdue Clean Air Act updates that can help tame this problem."

The Great Lakes region's five worst coal-fired power plants for mercury pollution are: Shawville (Clearfield County, PA); Monroe (Monroe County, MI); Homer City (Indiana County, PA); Cardinal (Jefferson County, OH); and Sherburne County (Sherburne County, MN). (See the complete list below of the worst 25.) A dozen power plants in Ohio and Indiana -- owned in whole or part by American Electric Power -- accounted for 19 percent of all mercury emitted in 2010 from the total of 144 coal-fired power plants in the region.

U.S. Senator James Inhofe, R-OK, recently filed a Congressional Review Act (CRA) resolution (S.J. Res. 37) to void health standards reducing mercury and other toxic air pollution from power plants and to permanently block EPA from re-issuing similar safeguards.

Cindy Copeland, report author and formerly with the EPA Air Program, said: "Mercury is poisoning the Great Lakes and the three states - Ohio, Indiana and Pennsylvania -- that impose no rules are by far the worst offenders. Airborne mercury from coal-fired power plants in the Great Lakes Region harms our health, and the benefits of reducing mercury emissions are well worth the cost. With a reduction of health costs to the economy at up to $90 billion, it is hard to say no to this."

In the Great Lakes region, there are more than 144 coal-fired power plants which pumped over 13,000 pounds of mercury into the air in 2010. Mercury pollution from these plants region accounts for close to 25 percent of the nation's total. The Great Lakes region is comprised of the five Great Lakes (Erie, Ontario, Huron, Michigan, and Superior) and the eight surrounding states (Illinois, Indiana, Michigan, Minnesota, Ohio, Pennsylvania, New York, and Wisconsin).

Eating poisoned fish is the primary cause of mercury poisoning of humans. Mercury is a neurotoxin that harms the brain, heart, central nervous system, kidneys, lungs, and immune system. Young children and developing fetuses are most at risk, and can suffer developmental problems from mercury poisoning.

The U.S. Environmental Protection Agency (EPA) recently issued nationwide rules to require coal-fired power plants to limit airborne mercury emissions and other toxic air pollutants by 2015. The technologies to meet the EPA's mercury limits are widely available and effective.

Based on projected reductions in fine particulate emissions due to the combined benefits of various air toxic pollution controls, the EPA has projected that the benefits of its Mercury and Air Toxics Standards (MATS) far outweigh the costs of pollution controls. The health benefits of the MATS are projected to be worth $37 to $90 billion in 2016 alone. The EPA has projected that the majority of the benefits would be reaped in the eastern United States, including the Great Lakes region.

Mercury emitted into the air from coal-fired power plants is by far the leading man-made source of mercury reaching the Great Lakes and the lakes, rivers, and streams of the Great Lakes region. This report lists the top 25 mercury emitting plants in the region. Mercury pollution from plants outside the region also contributes to the overall quantity of mercury found in the Great Lakes. When coal is burned to produce electricity, mercury is emitted into the air. The EPA estimates that coal-fired power plants are the largest man-made source of mercury pollution, accounting for 50 percent of mercury air emissions in the United States.
