NUCLEAR REGULATORY COMMISSION

[Docket Nos. 50-275 and 50-323]

 

Pacific Gas & Electric Co. Diablo Canyon Power Plant, Unit Nos. 1 
and 2; Environmental Assessment and Finding of No Significant Impact

    The U.S. Nuclear Regulatory Commission (the Commission) is 
considering issuance of amendments to Facility Operating License Nos. 
DPR-80 and DPR-82, issued to the Pacific Gas and Electric Company (the 
licensee), for operation of Diablo Canyon Power Plant, Unit Nos. 1 and 
2, located in San Luis Obispo, California.

Environmental Assessment

Identification of Proposed Action

    The proposed amendment would consist of a revision to Technical 
Specification 5.1.3, ``Map Defining Unrestricted Areas and Site 
Boundary for Radioactive Gaseous and Liquid Effluents.'' The change 
would revise the site area map description of the restricted area to a 
new smaller restricted area. The change proposed by the licensee is 
consistent with the requirements of the revised 10 CFR part 20. These 
changes are in response to the licensee's application for amendments 
dated July 7, 1993.

The Need for the Proposed Action

    The proposed action is needed in order to retain operational 
flexibility consistent with 10 CFR part 50, appendix I, concurrent with 
the implementation of the revised 10 CFR part 20.

Environmental Impacts of the Proposed Action

    The proposed revision, in regard to the new restricted area as 
referenced in the Technical Specifications (TS) will not increase the 
types or amounts of effluents that may be released offsite, nor 
increase individual or cumulative occupational radiation exposures. 
Therefore, the Commission concludes that there are no significant 
radiological environmental impacts associated with the proposed 
amendments.
    With regard to potential nonradiological impacts, the proposed 
changes do not affect nonradiological effluents and have no other 
environmental impact. Therefore, the Commission concludes that there 
are no significant radiological environmental impacts associated with 
the proposed amendments.

Alternative to the Proposed Action

    Since the Commission concluded that there are no significant 
environmental impacts associated with the proposed amendments to the 
TS, any alternative to the amendments will have either no significantly 
different environmental impact or will have greater environmental 
impact. The principal alternative would be to deny the requested 
amendments. This would not reduce environmental impacts as a result of 
plant operation.

Alternative Use of Resources

    This action does not involve the use of resources not previously 
considered in the Final Environmental Statement and Addendum related to 
the operation of Diablo Canyon Power Plant, Units 1 and 2, dated May 
1973 and May 1976, respectively.

Agencies and Persons Consulted

    The NRC staff reviewed the licensee's request and did not consult 
order agencies or persons.

Finding of No Significant Impact

    The Commission has determined not to prepare an environmental 
impact statement for the proposed license amendments. Based upon the 
foregoing environmental assessment, we conclude that the proposed 
action will not have a significant effect on the quality of the human 
environment.
    For further details with respect to this action, see the 
application for amendment dated July 7, 1993, which is available for 
public inspection at the Commission's Public Document Room, 2120 L 
Street NW., Washington, DC and at the California Polytechnic State 
University, Robert E. Kennedy Library, Government Documents and Maps 
Department, San Luis Obispo, California 93407.

    Dated at Rockville, Maryland, this 17th day of February 1994.

    For the Nuclear Regulatory Commission.
Theodore R. Quay,
Director, Project Directorate V, Division of Reactor Projects III/IV/V, 
Office of Nuclear Reactor Regulation.
