Dear Dr. Hurley:
Attached for your Staff's review is a copy of Commonwealth Edison's (Ceco) proposed revision to the LaSalle GSEP Annex, NSEP-LA-9201.
The revision is being submitted to incorporate upgraded Emergency Action Levels.
The changes to the GSEP have been reviewed in accordance with Commonwealth Edison procedures by the On-Site and Off-Site Review groups.
These reviews have concluded that the changes to the Annex do not decrease the-effectiveness of the plan, and the revised plan continues to meet the requirements of 10 CFR Appendix E.
LaSalle Station currently plans to implement the revised changes on February 24, 1993.
Therefore, Ceco requests your Staff's concurrence prior to February 24, 1993.
In accordance with 10 CFR 50.4(b)(5)(1), two copies of_the revised Annex have been provided to the Regional Office and one copy to the Resident Inspector.
If there are any questions, please direct them to this office.
Respectfully, noose 7MVS Jo nn Shields Nuclear Licensing Administrator Attachment cc:
