The Environmental Protection Agency (EPA) issued three rules on June 19, granting additional powers to states to determine their projected energy resource mixes, including nuclear energy. In response to the rules, utilities should be prepared for possible changes to state policies defining what constitutes “clean” energy and supporting reliability. The rules are intended to go into effect 30 days from their issuance. However, the implementation timeline for the rules is not certain because several states and organizations have stated they intend to challenge the rules in the federal courts.

As we reported last month, on June 20, the Council on Environmental Quality (CEQ) initiated the rulemaking process to revise its National Environmental Policy Act (NEPA)–implementing regulations by publishing an Advance Notice of Proposed Rulemaking (ANPR) in the Federal Register. The ANPR seeks public comments on “potential revisions to update the regulations and ensure a more efficient, timely, and effective NEPA process consistent with the national environmental policy stated in NEPA.” On July 11, the CEQ announced that it is extending the comment period, which was scheduled to close on July 20, for 31 days until August 20, 2018, in response to public requests for a time extension. See 83 Fed. Reg. 32,071 (July 11, 2018). The Federal Register notices also provide instructions for filing comments on the ANPR.
