NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-275 and 50-323]

 

Pacific Gas and 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 Licensing 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 revisions to the Technical 
Specifications in response to the revised 10 CFR part 20. The change 
would revise the limitations on the dose rate resulting from 
radioactive material released in gaseous effluents, and reflect the 
relocation of the prior 10 CFR 20.106 requirements to the new 10 CFR 
20.1302. 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 actual release rates as 
referenced in the Technical Specifications (TS) as a dose rate to the 
maximally exposed member of the public, 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 nonradiological environmental impacts associated 
with the proposed amendments.

Alternatives to the Proposed Action

    Since the Commission concluded that there are no significant 
envirommental 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.

Alternatives 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 Commission's staff reviewed the licensee's request and did not 
consult other 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.
