The U.S. Nuclear Regulatory Commission (NRC) is correcting a final rule that was published in the Federal Register on June 20, 2013, and effective on July 22, 2013. The final rule amended the NRC's environmental protection regulations by updating the Commission's 1996 findings on the environmental effect of renewing the operating license of a nuclear power plant. Compliance with the provisions of the rule is required by June 20, 2014. This correcting amendment is necessary to clarify and correct the revisions made to the statutory authority that is cited in the authority citation of the final rule.
