Availability Notice


This environmental impact statement (EIS) has been prepared to satisfy the requirements of the National Environmental Policy Act of 1969, as amended (NEPA). This EIS has been prepared in response to an application submitted to the U.S. Nuclear Regulatory Commission (NRC) by UniStar Nuclear Development, LLC, on behalf of Calvert Cliffs 3 Nuclear Project, LLC, and UniStar Nuclear Operating Services, LLC, (collectively known as UniStar) for a combined construction permit and operating license (combined license or COL). UniStar also submitted a joint Federal/State Application for the Alteration of Any Floodplain, Waterway, Tidal or Nontidal Wetland in Maryland to the U.S. Army Corps of Engineers (USACE or Corps) and the Maryland Department of the Environment (MDE). The proposed actions related to the UniStar applications are (1) NRC issuance of a COL for a new power reactor unit (Unit 3) at the Calvert Cliffs Nuclear Power Plant (CCNPP) in Calvert County, Maryland, and (2) Corps permit action on a Department of the Army (DA) Individual Permit application to perform certain activities on the site. The Corps is participating with the NRC in preparing this EIS as a cooperating agency and participates collaboratively on the review team.

This EIS includes the analysis by the NRC and the Corps staff that considers and weighs the environmental impacts of constructing and operating a new nuclear unit at the Calvert Cliffs site and at alternative sites and mitigation measures available for reducing or avoiding adverse impacts. This EIS also addresses consultation for Federally listed species, cultural resources, and essential fish habitat (EFH).

This EIS includes the evaluation of the proposed project's impacts to waters of the United States pursuant to Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899. The Corps will base its evaluation of the DA Individual Permit application on the requirements of Corps regulations, the Clean Water Act Section 404(b)(1) Guidelines, and the Corps public interest review (PIR) process.

After considering the environmental aspects of the proposed NRC action, the NRC staff's recommendation to the Commission is that the COL be issued as requested. This recommendation is based on (1) the application, including the Environmental Report (ER), submitted by UniStar and responses to requests for additional information (RAI); (2) consultation with Federal, State, Tribal, and local agencies; (3) the staff's independent review; (4) the staff's consideration of public comments related to the environmental review that were received during the public scoping process and on the draft EIS; and (5) the assessments summarized in this EIS, including the potential mitigation measures identified in the ER and this EIS. The Corps permit decision will be made following issuance of this final EIS.
