Clean Air Mercury Rule (CAMR)

The Clean Air Mercury Rule (CAMR) is setting performance standards for new coal-fired power plants by nominally capping mercury emissions from new and existing plants at 38 tons per year (tpy) from 2010 to 2017 and 15 tpy in 2018 and thereafter; these down from 48.5 tpy in 1999. To implement the CAMR, 21 states with non-zero emissions adopted EPA’s new source performance standards and cap and trade program with little or no modification. By December 2007, 23 other states had proposed or adopted more stringent requirements; 16 states prohibited or restricted interstate trading of mercury emissions.
