7590-01-P UNITED STATES NUCLEAR REGULATORY COMMISSION WOLF CREEK NUCLEAR OPERATING CORPORATION DOCKET NO. 50-482 WOLF CREEK GENERATING STATION ENVIRONMENTAL ASSESSMENT AND FINDING OF 1
l NO SIGNIFICANT IMPACT l
The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of i
an exemption to Facility Operating License No. NPF-42, issued to Wolf Creek Nuclear Operating Corporation (WCNOC), for operation of the Wolf Creek Generating Station, located in Coffey County, Kansas.
ENVIRONMENTAL ASSESSMENT Identification of the Prooosed Action-The proposed action would exempt WCNOC from certain requirements of 10 CFR 50.60 and 10 CFR Part 50, Appendix G. The proposed exemption,would allow WCNOC to apply American Society for Mechanical Engineers (ASME) Code Case N-514 for determining Wolf Creek Generating Station's cold overpressurization mitigation system (COMS) pressure setpoint.
The proposed action is in accordance with the licensee's application for exemption dated December 29,1998.

l 2-The Need for the Proposed Actiort The proposed exemption is needed to support an amendment to the Wolf Creek Technical Specifications which will revise the heatup, cooldown and COMS curve's. The use of ASME Code Case N-514 would allow an increased operating band for system makeup and pressure control to allow operational flexibility.
Environmental Imonets of the Proocsed Action:
The Commission has completed its evaluation of the proposed action and concludes that application of Code Case N-514 represents's special circumstance in accordance with 10 CFR 50.12(a)(2)(li) on specific exemptions, such that the specife requirements of 10 CFR 50.60 and Appendix G are "...not necessary to achieve the underlying purpose of the rule," which in this case is to protect the reactor vessel from brittle fracture.
1 The proposed action will not increase the probability or consequences of accidents, no changes are being made in the types of any effluents that may be released off site, and there is no significant increase in occupational or public radiation exposure. Therefore, there are no significant radiological environmental impacts associated with the proposed action.
With regard to potential non-radiological impacts, the proposed action does not involve any historic sites. It does not affect non-radiological plant emuents and has no other environmental impact. Therefore, there are no significant non-radiological environmental impacts associated with the proposed action.
1 Accordingly, the Commission concludes that there are no significant environmental impacts associated with the proposed action.

. Altematives to the Proposed Action:
As an altomative to the proposed action, the staff considered denial of the proposed action (i.e., the 'no-action" altamative). Denial of the application would result in no change in current environmental impacts. The environmentalimpacts of the proposed action and the altamative action are similar.
Altemative Use of Resources:
This action does not involve the use of any resources not previously considered in the Final Environmental Statement for the Wolf Creek Generating Station dated June 1982.
Agencies and Persons Consulted:
In accordance with its stated policy, on March 5,1999, the staff consulted with the Kansas State official, Mr. Vick Cooper, of the Kansas Department of Health and Environment, regarding the environmentalimpact of the proposed action. The State official had no comments.
MNDING OF NO SIGNIFICANTIMPACT On the basis of the environmental assessment, the Commission concludes that the proposed action will not have a significant effect on the quality of the human environment.
Accordingly, the Commission has determined not to prepare an environmental impact statement for the proposed action.
