ZION NUCLEAR GENERATING STATION EVALUATION OF SIGNIFICANT I HAZARD CONSIDERATIONS FOR PROPOSED CHANGES TO l APPENDIX A TECHNICAL SPECIFICATIONS i FACILITY OPERATING LICENSES -l' l DPR 39 AND DPR-48 SUPPLEMENT TO LICENSE AMENDMENT REQUEST 96-02 )

)

Commonwealth Edison has evaluated the previously proposed amendment and I determined that it involves no significant hazards considerations. This was documented in the original License Amendment Request (Ref.1). This supplement to the LAR changes two Technical Specifications to ensure the bounding analysis assumptions of the PTLR are maintained, and graphically illustrates information that had previously been identified in a text. Since these changes are either more restrictive, or are editorial in nature, the changes are bounded by the previous evaluation of significant hazards considerations.

Therefore, the changes contained in this supplement do not alter Comed's previous conclusion that the proposed amendment does not involve a significant increase in the probability or consequences of a previously evaluated accident, does not create the possibility of a new or different kind of accident from any previously evaluated accident, and does not involve a significant reduction in a margin of safety.

A'ITACHMENT D ZION NUCLEAR GENERATING STATION ENVIRONMENTAL ASSESSMENT STATEMENT FOR PROPOSED CHANGES TO APPENDIX A TECHNICAL SPECIFICATIONS FACILITY OPERATING LICENSES DPR-39 AND DPR-48 SUPPLEMENT TO LICENSE AMENDMENT REQUEST 96-02 The proposed changes to the previous license amendment request were evaluated against the criteria for and identification of licensing and regulatory actions requiring environmental assessment in accordance with 10 CFR 51.21. It was determined that the proposed changes meet the criteria for categorical exclusion as provided for under 10 CFR 51.22(c)(9). This was documented in the original License Amendment Request (Ref.1). These changes do not change any of the original evaluations and determinations. Therefore the conclusions of the original environmental assessment remain valid.
