Clean Air Mercury Rule (CAMR)
On March 15, 2005, the Environmental Protection Agency (EPA) issued the Clean Air Mercury Rule (CAMR), the nation’s first-ever federal rule to regulate mercury emissions from coal-fired power plants.
The Clean Air Mercury Rule builds on the Clean Air Interstate Rule (CAIR) to cut mercury emissions from utilities by nearly 70% at full implementation. Both the Clean Air Mercury Rule and the Clean Air Interstate Rule are part of the suite of inter-related rules collectively known as the Clean Air Rules of 2004, which together address ozone and fine particle pollution, non-road diesel emissions, and power plant emissions of sulfur dioxide, nitrogen oxide and mercury.
Under the CAMR, mercury emissions will be capped in two phases:
- Phase I – Mercury cap set at 38 tons beginning in 2010
- Phase II – Mercury cap set at 15 tons beginning in 2018
