NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 205!6 0001 s~,
SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION t
RELATED TO AMENDMENT N0. 85 TO FACILITY OPERATING LICENSE NO. DPR-22 NORTHERN STATES POWER COMPANY MONTICELLO NUCLEAR GENERATING PLANT DOCKET NO. 50-263
1.0 INTRODUCTION
By letter dated December 31, 1992, the Northern States Power Company (NSP, the licensee) requested an amendment to the Technical Specifications appended to facility Operating License No. DPR-22 for the Monticello Nuclear Generating Pl ant. The proposed amendment would revise Technical Specification Surveillance Requirement 4.13.B.I.e, " Fire Suppression Water System," by changing the American Society for Testing and Materials (ASTM) standards which are to be followed when performing required sampling and analysis of the diesel fire pump fuel oil supply.
The current technical specifications require that a sample of the fuel oil be obtained in accordance with ASTM D270-65, " Sampling of Petroleum and Petroleum Products." This would be revised such that the sample will be obtained in accordance with ASTM D4057-88, " Manual Sampling of Petroleum and Petroleum Products." Further, the surveillance requirement would be revised to reflect a later edition of the ASTM standard for testing.
The current specification requires verification that the fuel oil is within limits specified in ASTM D975-74, " Standard Specification for Diesel Fuel Oils." This would be revised to check the oil against ASTM D975-91.
(The two digits appended to the standard designation indicate the year in which the revision of the standard was promulgated.)
2.0 EVALUATION Because they are outdated, the ASTM standards identified in the current technical specifications are no longer preferred for use.
The standard for sampling (ASTM D270-65, " Sampling of Petroleum and Petroleum Products") was withdrawn by ASTM in 1983 and was replaced by ASTM D4057, " Manual Sampling of Petroleum and Petroleum Products." The licensee finds that the new standard allows the use of sampling methods better suited to the small fuel oil storage tanks in use at Monticello. The standard for analysis (ASTM D975-74,
" Standard Specification for Diesel Fuel Oils") has undergone several revisions since 1974. The proposed amendment would identify the latest revision, issued in 1991.

~
s The new standards have been designated by ASTM to replace the ASTM. standards identified in the current technical specifications. The new standards will provide an equivalent level of assurance of diesel fire pump fuel oil quality.
NRC finds sampling and analysis of the fuel oil in accordance with approved standards to be acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Minnesota State Official was notified of the proposed issuance of the amendment. The State Official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a Surveillance Requirement.
The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration and there has been no public comment on such finding (58 FR 25861).
Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.??(b), no environmental impact statement or environmental assessment need be p.epared in connection with the issuance of the amendment.
5.0 CONCLUSION
The staff has concluded, based on the considerations discessed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
