7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION l COMMONWEALTH EDISON COMPANY l

DOCKET NOS. 50-237/249 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Comission) is considering issuance of exemptions from certain requirements of Section III.G of Appendix R to 10 CFR Part 50 to Commonwealth Edison Company (CECO) (the licensee) for Dresden Nuclear Power Station, Unit Nos. 2 and 3, located at the licensee's site in Grundy County, Illinois.

ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:

The proposed action would grant exemptions from certain requirements of

'Section III.G 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 damage. The exemptions are technical since the licensee must demonstrate that fire protection configurations meet the specific requirements of Section III.G or that alternate! fire protection configurations can be justified by an acceptable fire hazard 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 proposed fire protection at the plant for these items are the most practical method for meeting 'he intent of Appendix R and literal compliance would not significantly enhance the fire protection capability at Dresden Station.

Environmental impacts of the Proposed Action .

The proposed exemptions will provide a degree of fire protection such that there is_no increase in the risk of fires at Dresden. Consequently, the probability of fires has not been increased and the post-fire radiological releases will not be greater than previously determined nor do the proposed exemptions otherwise affect radiological plant effluents. Therefore, the Commission concludes that there are no significant radiological environmental impacts associated with the proposed exemptions.

With regard to potential nonradiological impacts, the proposed exemptions involve features located entirely within the restricted areas as defined in 10 CFR Part 20. They do not affect nonradiological plant effluents and have no other environmental impact. Therefore, the Commission concludes that there

.are no significant nonradiological environmental impacts associated with the proposed exemptions.

Alternative Use of Resources: This action involves no use of resources not previously considered in the Final Environmental Statement dated November 1973 for the Dresden Nuclear Power %ation, Unit Nos. 2 and 3.

Agencies and Persons Consulted: The NRC 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 exemptions.

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.
