SUBJECT:

LASALLE COUNTY STATION, UNITS 1 AND 2-CORRECTION LETTER FOR CONFORMING LICENSE AMENDMENTS TO INCORPORATE THE MITIGATION STRATEGIES REQUIRED BY SECTION B.5.b. OF COMMISSION ORDER EA-02-026 AND THE RADIOLOGICAL PROTECTION MITIGATION STRATEGIES REQUIRED BY COMMISSION ORDER EA-06-137 (TAC NOS.

MD4506 AND MD4507)

Dear Mr. Hanson:

By letter dated August 9, 2007 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML072200022), the U.S. Nuclear Regulatory Commission (NRC) staff issued license conditions to Renewed Facility Operating License (RFOL) Nos. NPF-11 and NPF-18 for the LaSalle County Station, Units 1 and 2, respectively. The conforming amendments were to incorporate the mitigation strategies required by Section B.5.b. of Commission Order EA-02-026, "Order for Interim Safeguards and Security Compensatory Measures."

The NRC staff identified the following editorial errors:

On page 8 of the RFOL No. NPF-11, in paragraph (44)(b)5, and page 7 of the RFOL No.

NPF-18, in paragraph (28)(b)5, the word "equipment" should have completed the phrase.

These errors were inadvertently introduced during the administrative* processing of the conforming license amendment. The corrections do not change any of the conclusions associated with the issuance of conforming amendment and do not affect the associated notice to the public. Please replace RFOL pages with the enclosed corrected pages. We regret any inconvenience caused by these errors.

B. Hanson If you have any questions, please contact me at 301-415-3308 or via e-mail at Bhalchandra.Vaidya@nrc.gov.

Sincerely, Bhalchandra K. Vaidya, Project Manager Plant Licensing Branch Ill Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-373 and 50-37 4
