###### Nuclear Regulatory Commission

          - [Docket No. 50-261; NRC-2010-0062]

                    The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an exemption pursuant to Title 10 of the                     *Code of Federal Regulations*                     (10 CFR) Section 73.5, “Specific exemptions,” from the implementation date for certain new requirements of 10 CFR Part 73, “Physical protection of plants and materials,” for Facility Operating License No. DPR-23, issued to Carolina Power & Light Company (the licensee), for operation of the H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP), located in Darlington County, South Carolina. In accordance with 10 CFR 51.21, “Criteria for and identification of licensing and regulatory actions requiring environmental assessments,” the NRC prepared an environmental assessment documenting its finding. The NRC concluded that the proposed action will have no significant environmental impact.                

## Environmental Assessment

### Identification of the Proposed Action

The proposed action would exempt HBRSEP from the required implementation date of March 31, 2010, for two new requirements of 10 CFR part 73. Specifically, HBRSEP would be granted an exemption from being in full compliance with certain new requirements contained in 10 CFR 73.55, “Requirements for physical protection of licensed activities in nuclear power reactors against radiological sabotage,” by the March 31, 2010, deadline. The licensee has proposed an alternate full compliance implementation date of December 30, 2010, approximately 9 months beyond the date required by 10 CFR part 73. The proposed action, an extension of the schedule for completion of certain actions required by the revised 10 CFR part 73, does not involve any physical changes to the reactor, fuel, plant structures, support structures, water, or land at the HBRSEP site.

The proposed action is in accordance with the licensee's application dated November 30, 2009.

### The Need for the Proposed Action

                    The licensee has stated that it has performed an extensive evaluation of the revised 10 CFR part 73 and will achieve compliance with a vast majority of the revised rule by the March 31, 2010, compliance date. However, the licensee has determined that implementation of two specific provisions of the rule will require more time to implement because they involve upgrades to the security system that require significant physical modifications (                    *e.g.,*                     the relocation of certain security assets to a new security building that will be constructed, and the addition of certain power supplies). Therefore, the licensee proposes to extend the compliance date beyond March 31, 2010, to December 30, 2010, in order to complete these security modifications.                

### Environmental Impacts of the Proposed Action

                    The NRC has completed its environmental assessment of the                           ( print page 8411)                        proposed exemption. The staff has concluded that the proposed action to extend the implementation deadline would not significantly affect plant safety and would not have a significant adverse effect on the probability or consequences of an accident.                

                    The proposed action would not result in an increased radiological hazard beyond those previously analyzed in the environmental assessment and finding of no significant impact made by the Commission in promulgating its revisions to 10 CFR part 73 as discussed in a                     **Federal Register**                     notice dated March 27, 2009 (74 FR 13967). There will be no change to radioactive effluents that affect radiation exposures to plant workers and members of the public. Therefore, no changes or different types of radiological impacts are expected as a result of the proposed exemption.                

The proposed action does not result in changes to land use or water use, or result in changes to the quality or quantity of non-radiological effluents. No changes to the National Pollution Discharge Elimination System permit are needed. No effects on the aquatic or terrestrial habitat in the vicinity of the plant, or to threatened, endangered, or protected species under the Endangered Species Act, or impacts to essential fish habitat covered by the Magnuson-Stevens Act are expected. There are no impacts to the air or ambient air quality. 

There are no impacts to historical and cultural resources. There would be no impact to socioeconomic resources. Therefore, no changes to or different types of non-radiological environmental impacts are expected as a result of the proposed exemption.

Accordingly, the NRC concludes that there are no significant environmental impacts associated with the proposed action. In addition, in promulgating its revisions to 10 CFR part 73, the Commission prepared an environmental assessment and published a finding of no significant impact (March 27, 2009, 74 FR 13967).

The NRC staff's safety evaluation will be provided as part of a letter to the licensee approving the exemption to the regulation, if granted.

### Environmental Impacts of the Alternatives to the Proposed Action

                    As an alternative to the proposed action, the NRC staff considered denial of the proposed action (                    *i.e.,*                     the “no action” alternative). Denial of the exemption request would result in no change in current environmental impacts. If the proposed action were denied, the licensee would have to comply with the March 31, 2010, implementation deadline. The environmental impacts of the proposed exemption and the “no action” alternative are similar.                

### Alternative Use of Resources

The action does not involve the use of any different resources than those considered in the Final Environmental Statement for the HBRSEP, dated April 1975, as supplemented through the “Generic Environmental Impact Statement for License Renewal of Nuclear Plants: H.B. Robinson Steam Electric Plant, Unit 2—Final Report (NUREG—1437, Supplement 13).”

### Agencies and Persons Consulted

In accordance with its stated policy, on January 22, 2010, the staff consulted with the South Carolina State official, Mike Gandy of the South Carolina Bureau of Land and Waste Management, regarding the environmental impact of the proposed action. The State official had no comments.

## Finding of No Significant Impact

On the basis of the environmental assessment, the NRC concludes that the proposed action will not have a significant effect on the quality of the human environment. Accordingly, the NRC has determined not to prepare an environmental impact statement for the proposed action.

                    For further details with respect to the proposed action, see the licensee's letter dated November 30, 2009.
