Federal Mercury Rule

The Clean Air Mercury Rule (CAMR) was promulagated by the USEPA in May 2005. It requires a reduction of mercury emissions from new and existing coal-fired power plants through a cap on emissions expressed as an annual state emission budget that includes two phases of reductions beginning in 2010 and 2018. The department is currently revising its state rule in response to the federal rule. Please go to Wisconsin's Mercury Rule And Revisions for more information on adopting the federal rule.

EPA reconsideration of the Clean Air Mercury Rule

On October 28, 2005, EPA announced that it would reconsider the CAMR as well as its determination that it was not appropriate or necessary to regulate hazardous air emissions from utilities under Section 112 of the Clean Air Act. This action is in response to petitions filed by several states, tribes, industry, and environmental groups. Comments to EPA are due December 19, 2005. Below are the Federal Register notices and supporting documents prepared by EPA.
