7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION VIRGINIA ELECTRIC AND POWER COMPANY DOCKET NOS. 50-280 AhD 50-281 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-32 and DPR-37, issued to Virginia Electric and Power Company (the licensee), for operation of the Surry Power Station, Units 1 and 2, located in Surry County, Virginia.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The proposed amendments would revise the provisions in the Technical Specifications (TS) by:
(1) raising the minimum required high level intake canal water level from 18 feet to 23 feet, (2) increasing the requirement from two to three emergency service water pumps to be operable with provisions for limited duration outages, and (3) providing operability and surveillance requirements for the new safety-related high level intake canal level actuation system.
The proposed action is in accordance with the licensee's application for amendment dated March 27, 1989.
The Need for the Proposed Action:
The proposed changes to the TS are required to maintain a higher water level in the intake canal to ensure adequate flow through the component cooling water (CCW) system and other safety-related heat exchangers during accident conditions.

l 1 Environmental Impacts of the Proposed Action:
l The Commission has completed its evaluation of the proposed revisions to the TS. The proposed revisions would require the licensee to raise the water level in the intake canal from 18 feet to 23 feet; require three emergency service water pumps to be operable; and cause isolation of the main condenser i
and certain service water isolation valves upon receipt of a signal from the i
safety-related canal low level actuation system.
The proposed revisions will also require operability and surveillance requirements for the new safety-related canal water level actuation system. The proposed changes do not increase the probability or consequences of accidents, no changes are being made in the types of any effluents that may be released offsite, and there is no significant increase in the allowable individual or cumulative occupational radiation exposure. Accordingly, the Connission concludes that this proposed action would result in no significant radiological environmental impact.
With regard to potential non-radiological impacts, the proposed changes to the TS involve systems which are not located within the restricted area as defined in 10 CFR Part 20. These changes do not affect non-radiological plant effluents 4:40 have no other envirconantal impact.
Therefore, the Commission concludes that there are no signifkant non-ractological environmental impacts associated with the proposed amendment.
The Notice of Consideration of Issuance of Amendments and Opportunity for Hearing in ccnnection with this action was published in the FEDERAL REGISTER on April 10, 1989 (54 FR 14303). No request for hearing or petition for leave to intervene was filed following this notice.

Alternatives to the Proposed Action:
Since the Commission concluded that there are no significant environmental effects that would result from the proposed action, any alternatives with equal or greater environmental impacts need not be realuated.
The principal alternative would be to deny the requested amendments. This would not reduce environmental impacts of plant operation and would result in reduced operational flexibility.
Alternative Use of Resources:
This action does not involve the use of any resources not previously considered in the Final Environmental Statements for the Surry Power Station, Units 1 and 2.
Agencies and Persons Consulted:
The NRC staff reviewed the licensee's request and did not consult other agencies or persons.
FINDING 0F 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.
