Power plant carbon emission standards

The U.S. Environmental Protection Agency (EPA) has finalized rules under the Clean Air Act (CAA) regulating carbon emissions from power plants.

The EPA set these standards using two sections of the CAA:

  1. Section 111(b) is a federal program that establishes emissions standards for new, modified and reconstructed stationary sources; and
  2. Section 111(d) is a state based program for existing stationary sources where EPA establishes guidelines and the states design programs to achieve the needed emissions reductions.

Existing power plants

Final EPA rule (August 2015)

The EPA's regulation of carbon emissions from existing fossil-fuel power plants is known as the Clean Power Plan. The EPA finalized the Clean Power Plan on August 3, 2015. The final rule, along with the related technical documents and other information supporting the rule, can be found on EPA's Clean Power Plan for Existing Power Plants [exit DNR].

On December 22, 2015, DNR and the Public Service Commission of Wisconsin (PSCW) requested that EPA reconsider its final rule.

In the final rule, EPA introduced the Clean Energy Incentive Program (CEIP), an optional program that states may use to incentivize early investments in wind and solar power generation, as well as energy efficiency measures in low-income communities. On December 15, 2015, DNR and PSCW submitted comments to EPA on the CEIP.

Proposed federal plan for the Clean Power Plan (August 2015)

On August 3, 2015, EPA proposed a federal plan for the Clean Power Plan that will also serve as a model rule for states developing state plans. Information about the proposal can be found on EPA's Clean Power Plan for Existing Power Plants [exit DNR].

On January 21, 2016, DNR and PSCW submitted comments to EPA on the proposed federal plan.

Proposed EPA rule (June 2014)

The EPA proposed carbon pollution standards for existing power plants on June 2, 2014. The proposed rule and supporting materials can be found on EPA's Clean Power Plan Proposed Rule [exit DNR].

The DNR and PSCW submitted two sets of comments to EPA related to the proposed Clean Power Plan on December 1, 2014.

EPA call for comments (September 2013)

On September 23, 2013, EPA issued a call for comments to states and other stakeholders [PDF exit DNR] to provide input into the development of carbon pollution standards for existing power plants. On December 13, 2013, DNR and PSCW submitted comments to EPA in response to this request.

New, modified and reconstructed power plants

Final EPA rule (August 2015)

On August 3, 2015, EPA finalized standards to reduce carbon emissions from new, modified and reconstructed power plants. These standards apply to new sources built after January 8, 2014, and existing units that are modified or reconstructed as defined by the Clean Air Act and implementing regulations. The EPA established separate standards for two types of fossil-fuel fired sources:

  • stationary combustion turbines, which are generally fueled by natural gas; and
  • electric utility steam generating units, which are generally fueled by coal.

The EPA's final rule and associated technical information can be found on EPA's Carbon Pollution Standards for New, Modified and Reconstructed Power Plants [exit DNR].

On December 22, 2015, DNR and the Public Service Commission of Wisconsin (PSCW) requested that EPA reconsider its final rule.

Proposed EPA rules (2012-2014)

The EPA proposed carbon pollution standards for new and modified/reconstructed power plants in two separate actions.

Proposed EPA rule for modified/reconstructed power plants (June 2014)

On June 2, 2014, EPA issued a proposed carbon emission standard for modified and reconstructed power plants [exit DNR].

On October 16, 2014, DNR submitted comments on the proposed rule.

Proposed EPA rules for new power plants (March 2012 and September 2013)

The EPA issued a proposed carbon pollution standard for new power plants (New Source Performance Standard, or NSPS) on March 27, 2012. In response to the comments received on this proposal, EPA made substantial revisions to the original proposal and issued a new proposal on September 20, 2013. Both proposals can be found on EPA's Carbon Pollution Standards for New, Modified and Reconstructed Power Plants [exit DNR].

Wisconsin submitted comments in response to both proposed NSPS regulations.
