MILLSTONE POWER STATION UNIT 2 CONTROL ROOM ISOLATION RADIATION MONITORING INSTRUMENTATION ADMINISTRATIVE CORRECTION In a letter dated July 15, 2004, Dominion Nuclear Connecticut, Inc. (DNC) requested to amend Operating License DPR-65 for Millstone Power Station Unit 2 to address the resolution of a non-conservative Technical Specification.

During a review of the correspondence, it was determined that additional pages, not part of the requested changes, were inadvertently included as part of Attachment 3 of the letter. Therefore, DNC requests that Attachment 3 of the subject letter be withdrawn and that the enclosure to this letter be inserted in its place.

The substitution of the enclosure to this letter in place of Attachment 3 of the July 15, 2004 letter does not alter the proposed amendment or the Significant Hazards Consideration pursuant to the provisions of 10 CFR 50.92 found in Attachment 1 of the July 15, 2004 letter.

In accordance with 10CFR50.91(b), a copy of this letter is being provided to the State of Connecticut.

If you should have any questions regarding this submittal, please contact Mr. Paul R.
