Description:
The U.S. Environmental Protection Agency has promulgated the Clean Air Mercury Rule (CAMR) to permanently cap and reduce mercury emissions in the U.S. This rule makes the U.S. the first country in the world to regulate mercury emissions from coal-fired power plants. The first phase of CAMR implementation (2010) sets a national cap of 38 tons with emission reductions coming primarily as a co-benefit of technologies for SO2 and NOx control. The second phase (2018) sets a national annual cap of 15 tons. These deeper emissions reductions will likely require the use of dedicated mercury control technologies. The time frame of CAMR implementation will allow for further development and testing of these technologies. The CAMR is expected to make reductions in mercury emissions that are transported regionally and deposited domestically, and it will reduce emissions that contribute to atmospheric mercury worldwide.
