i UNITED STATES NUCLEAR REGULATORY COMMISSION PUBLIC SERVICE COMPANY OF COLORADO 4
FORT ST. VRAIN NUCLEAR GENERATING STATION i
DOCKET NO. 50-267 ENVIRONMENTAL ASSESSMENT AND FINDING OF e
}
NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an exemption from the revised 10 CFR Part 20 requirements of 4
the Code of Federal Reaulations to the Public Service Company of Colorado (PSC or the licensee) for the Fort St. Vrain Nuclear Generating Station (FSV),
pursuant to 10 CFR 20.2301.
i ENVIRONMENTAL ASSESSMENT:
i Identification of Proposed Action:
The approval of the exemption would permit PSC to complete the planned i
decommissioning of Fort St. Vrain without implementing the revised 10 CFR l
Part 20, and in effect operate for 2 years beyond January 1,1994, under the radiation protection provisions of 10 CFR 20.1 through 20.601.
PSC began i
dismantlement of FSV following the Commission's issuance of the Order to l
Authorize Decommissioning, November 23, 1992. By January 1,1994, PSC will have l
completed approximately 40 percent of the dismantlement of FSV. PSC anticipates 9304190287 930407 PDR ADOCK 05000267 p
I 2
I l
that the FSV license will be terminated and the facility released for unrestricted release in late 1995.
The Need for the Proposed Action:
The exemption would eliminate the required implementation of the revised 10 CFR Part 20 requirements by January 1,1994, and allows PSC to complete the I
decommissioning of FSV under the current radiation protection provisions of l
10 CFR Parts 20.1 through 20.601 for the remaining 24 months beyond January 1, 1994. The staff determined granting the proposed exemption would ensure adequate protection of the workers and the public and reduce unnecessary costs for PSC based on the following information provided in the Decommissioning Plan: (1) the t
estimated occupational dose projections are well within the lower occupational limits of the revised 10 CFR Part 20 and the intent of the revised Part 20 would be realized; and (2) the estimated collective dose projection (260 man-rems to approximately 300 workers over the remaining 24-month period) to complete l
decommissioning is reasonable, and reflects a minimum-dose alternative approach.
1 Environmental Imoact of the Proposed Action:
The proposed action to allow PSC to complete the decommissioning of FSV under the current radiation protectkn provisions of 10 CFR 20.1 through 10 CFR 20.601 for the remaining 24 months beyond January 1, 1994,. will have no significant environmental impact.
The staff initially evaluated the decommissioning of FSV before issuing the November 23, 1992, Order to l
Decommission, and concluded that the decommissioning of FSV, based on the current' radiation protection requirements of 10 CFR 20.1 through 10 CFR 20.601, would i
have no significant impact on the quality of the human environment.
PSC has i
recently implemented administrative controls for dose limits that are more stringent than the current 10 CFR Part 20 requirements, and well within the
li
\\
3 l
revised 10 CFR Part 20 limits.
Although the admistrative controls could be i
changed, the Decommissioning Plan estimated collective dose projection for occupational and ALARA purposes (260 man-rems to approximately 300 workers over l
h the remaining 24-month period) to complete decommissioning is reasonable, and well within the lower occupational limits of the revised 10 CFR Part 20.
The proposed exemption does not affect plant nonradiological effluents and j
thus has no adverse environmental impact.
In addition, the proposed exemption t
i j
would not authorize a change in licensed activities or effect changes in the l
t
[
Technical Specifications with regard to allowable types or amounts of radiological effluents.
With regard to potential radiological and non-radiological impacts, the Commission concludes that there are no measurable radiological or non-radiological impacts associated with this exemption.
I i
Alternatives to the Proposed Action:
l 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 evaluated.
L Alternative Use of Resources:
This action does not involve the use of any resources not previously l
t considered in the Supplement to the Environmental Report for FSV.
l l
i Acencies and Persons % solted:
The licensee ir.itiated this exemption.
The NRC staff is reviewing its request. The State of Colorado was contacted,-and n d no comments.
FINDING OF NO SIGNIFICANT IMPACT:
The Commission has determined not to prepare an environmental
l l.
4 l.
impact statement for the proposed exemption.
J Based upon this environmental assessment, the staff concludes that the proposed action will not have a significant effect on the quality of the human environment.
