State Regulations: Seventeen States Have Established Mercury Emission Limits on Coal Plants
State Year Enacted Policy/RuleNew Hampshire 2002 Requires 75% reduction in annual mercury emissions from coal plants compared to 1996/97 emissions.
Connecticut 2003 Requires coal-fired power plants to achieve either an emissions standard of 0.6 lb/tBtu or a 90% efficiency in technology installed to control mercury emissions.
New Jersey 2004Requires a 90% reduction of mercury emissions from coal-fired power plants by the end of 2007. Plants have the option of meeting the standards in 2012 if they also make major reductions in their emissions of sulfur dioxide, nitrogen oxides, and fine particulates.
Delaware 2006 Requires power plants to capture at least 80% of mercury beginning in 2009 and 90% beginning in 2013.Maryland 2006 Requires power plants to capture at least 80% of mercury beginning in 2010 and 90% beginning in 2013.Illinois 2006 Requires power plants to reduce mercury emission by 90% starting in July of 2009.
North Carolina 2006Requires power plants submit by January 1, 2013 detailed plans and timetables for achieving maximum technically and economically possible mercury reductions at each unit. Units that are not controlled by 2017 must be shut down.
Montana 2006Requires mercury emitti ng EGUs to achieve an emission rate lower than 0.9 lbs/TBtu by January 1, 2010. EGUs unable to meet this limit after installing an approved control strategy may apply for an alternative limit by July 1, 2011.
Minnesota 2006 Requires MN’s largest coal-fired power plants to cut mercury emissions by 90% by 2015.
Massachusetts 2007Requires requires power plants to capture at least 85% of mercury (or achieve a rate of 0.0075 lbs/GWh) by 2008 and 95% of mercury (or achieve a rate of 0.0025 lbs/GWh) by 2012.
New York 2007Phase I (2010): Power plants must reduce mercury emissions by 50%. Phase II (2015): Implementation of unit-based limits for each facility to reduce mercury emissions by 90% using Maximum Available Control Technologies
Colorado 2007 Requires new or reconstructed units to achieve a minimum mercury capture rate of 90% and implement BACT.
Georgia 2007Multipollutant Control for EGUs (steam) requires four specific power plants to carry out feasibility studies for mercury controls by 2018. Mercury emissions from new EGUs requires the use of BACT to control mercury emissions.
Wisconsin 2008
Requires large (>150 MW) coal-fired power plants to either – a) achieve a 90 percent reduction in mercury emissions from coal by the year 2015; or b) reduce multiple pollutants, including nitrogen oxides (NOx) and sulfur dioxide (SO2), and achieve 90 percent reduction in mercury emissions six years laterRequires small (> 25 MW and < 150 MW) coal-fired power plants reduce their mercury emissions to BACT level.
South Carolina 2008 Requires power plants to install mercury emission monitoring equipment by June 2009.
Michigan 2009Requires EGUs to reduce mercury emissions by 90%, or achieve 75% mercury emission reductions along with nitrogen oxides (NOx) and sulfur dioxide (SO2) reductions.
Oregon 2010Caps mercury emissions from new EGUs and requires installation of mercury controls at existing ones. Total statewide mercury emissions limited to 60 lbs/year after 2018. New coal plants cannot emit more than 25 lbs per year
