SAFETY EVALVATIGN BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 7 TO LICENSE NPF-12 SOUTH CAROLINA E1.ECTRIC & GAS COMPANY SOUTH CAROLINA PUBLIC SERVICE AUTHORITY
]
INTRODUCTION By letter, dated October 19, 1982, the South Carolina Electric a Gas Company (SCEAG) requested a change to the Technical Specifications to provide for a tolerance on the hydrogen and oxygen content of the standard gas samples used in the channel calibration of the hydrogen and oxygen monitors in the waste gas holdup system explosive gas monitoring system.
EVALUATION The surveillance requirements for the hydrogen and oxygen monitc~s on page 3/4 3-79 require in part the conduct of a periodic channel calibration of the containment hydrogen monitors using standard gas samples. The licensee in its letter of October 19, 1982 requested that this surveillance requirements be changed to provide acceptable tolerances to be used in the procurement of the sample gases used for calibration of the instruments.
We have reviewed the above change and conclude that it is administrative in nature and consistent with the basis for our approvel of the design of the waste gas holdup system explosive gas monitoring system during the operating lice 1se stage of review.
ENVIRONMENTAL CONSIDERATION We have deternined that the amendment does not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact. Having made this determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR Section 51.5(d)(4), that an environmental impact statement or negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of this amendment.

2-CONCLUSION We have concluded, based on the considerations discussed above, that:
(1) because the amendment does not involve a significant increase in the proba-bility or consequences of accidents previously considered, does not create the possibility of an accident of a type different from any evaluated previously and does not involve a significant decrease in a safety margin, the anendment does not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be in compliance with the Comission's regulations and the issuance of this amendnent will not be inimical to the comon defense and security or to the health and safety of the public.
