EPA's proposed Clean Power Plan – South Dakota Comments


Updated 11/19/20

In June 2014, the U.S. Environmental Protection Agency released its proposed rule to regulate carbon emissions from existing power plants under the Clean Air Act §111(d). Interested parties had an opportunity to file written comments with the EPA by Dec. 1, 2014.

The South Dakota Public Utilities Commission hosted a forum in July 2014 at which Commissioners Gary Hanson, Chris Nelson and Kristie Fiegen, along with representatives of the state's electric utility providers, the EPA and South Dakota's congressional delegation, discussed the proposed rule and its anticipated effect on South Dakotans, particularly in terms of reliability and rates.


The PUC thoroughly analyzed the proposed rule and submitted written comments to the EPA on Dec. 1, 2014. In its comments, the PUC focused on four primary elements:

  • Educating the EPA about South Dakota's electric industry
  • Identifying concerns with EPA's short compliance timeline
  • Identifying technical issues with the building blocks EPA has specified for states to use to comply with the Clean Power Plan
  • Providing economic impacts forecasted for South Dakota
