' NOTICE OF ENVIRONMENTAL ASSESSMENT AND FINDING 0F N0 SIGNIFICANT IMPACT

(

The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of exemptions from the requirements of Appendix R to 10 CFR Part.50 to the Public Service Company of Colorado (the licensee) for the Fort St.

i i

Vrain Nuclear Generating Station located in Weld County, Colorado.

I j

ENVIRONMENTAL ASSESSMENT j Identification of Proposed Action: The proposed action would grant exemptions l 1

from certain requirements of Sections III.G and III.J of Appendix R to 10 CFR )

Part 50, which relate to fire protection features for ensuring that systems and associated circuits used to achieve and maintain safe shutdown are free of fire de mge and to the provision of emergency lighting. The exemptions are technical since the licensee must demonstrate that fire protection and emergency lighting configurations meet the specific requirements of Section III.G and III.J or that alternate fire protection and emergency lighting configurations can be justified by an acceptable analysis.

The Need for the Proposed Action: The proposed exemptions are needed because the features described in the licensee's request regarding the existing and l

proposed fire protection at the plant would result in a net benefit to the public health and safety that compensates for any decrease in safety that may result f rom the granting of this exemption request.

) Environmental Impacts of the Proposed Action: The proposed exemptions will i

provide a degree of fire protection such that there is no increase in the risk of fires at Fort St. Vrain. Consequently, the probability of fires has not been increased and the post-fire radiological releases will not be greater than previously determined nor does the proposed exemption otherwise affect radio-logical plant effluents. Therefore, the Commission concludes that there are .

not significant radiological environmental impacts associated with the proposed exemption.

With regard to potential nonradiological impacts, the proposed exemption involves features located entirely within the restricted areas as defined in 10 CFR Part 20. It does not affect nonradiological plant effluents and has no other environmental impact. Therefore, the Commission concludes that there are no significant nonradiological environmental impacts associated with the l

proposed exemption.  !

The Commission has determined not to pt:tpare an environmental impact statement for the proposed exemption.

i 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 licensee's letter dated April 1, 1985 (P-85113). The letter is available for public inspection I
