[External_Sender] Lee MET Tower Date: Thursday, March 29, 2018 10:47:11 AM
- Brian, Thanks for your phone mail message today and for the update you provided on a few of our issues.
You are correct that the Lee Permanent Met Tower was disassembled several years ago to address aviation issues. As related to the associated FSAR change, it was a documented decision on our part to only address the text pertaining to continuous monitoring - which obviously is not currently occurring via the Permanent Met Tower and also is not currently required due to the status of our project. The remaining discussion of the tower in the FSAR was not changed as the expectation is that the tower will be reconstructed to support the construction phase of the project - when that time comes. Our license change process documented justification of that decision (coped below).
I appreciate you sharing your concern with the FSAR. Ive asked my licensing folks to consider sending in a formal letter to document the status of the tower. Please let me know if you have any questions. I hope you have a nice Easter weekend.
Erik G. Wagner, P.E.

Church Street, Charlotte, NC 28202, Mail Code: EC01T Office: (704) 382-3949, Cell: (704) 650-9631 Justification Summary The Permanent Meteorological Tower (MET), formerly named Tower 3, at the Lee plant site has been disassembled because it is not required at this time. A proposed COLA change (N236) was prepared (pre-license) in support of the tower disassembly and the change was deferred in accordance with ISG-11 (630175-13). The FSAR change in this LBDCR is derived from deferred COLA change N236.
A decision was made to include only required changes in the 2017 FSAR update. As a result, COLA change N236 and FSAR Section 2.3.3 were reviewed to identify the minimum required changes as a result of the disassembly of Tower 3. It was determined that the only FSAR change required at this time is the deletion of the sentence noted in the Summary of Change above. COLA change N236, which
impacts several pages of the FSAR, will continue to be deferred and will be addressed in the future.
FSAR Section 2.3.3 describes meteorological monitoring for the pre-application (sometimes called preconstruction),
construction and operational phases of the plant. The pre-application phase for WLS is complete, and a decision to construct the plant has not been made. The met tower is not required in this interim period and therefore, the statement concerning continuous monitoring from preapplication through operation is being deleted.
