Dear Mr. Cook:

Sthject: Compilation of Information Requested for Completion of Staff _
/
Review of Phase 2 Underpinning of Midland Auxiliary Building Pursuant to the request of ffr. J. Mooney of your Company on l1 arch 11, 1982, is a compilation of the infomation needed for cmpletion of the fMC's review of " phase 2" of the construction activities for underpinninq of the Midland Auxiliary Buildinq.
" Phase 2" is cefined by the Construction Sequence Loqic Diagraa provided the staff during a January 18-19,1982 audit neeting (Enclosure 1 of our necting sumary dated fiarch 10,1987.), and generally provides for further deepening of the vertical access shaft, construction of limited drifts under the Feedwater Isolation Valvo Pits (FIVPs) and Turbina Building, and installation of certain piers.
Your prmpt attention to these matters should provide for staff concurrence with ninimal f anact to your present construction schedule.
The reporting and/or recordkeeping requirements contained in this affect fewer than ten respondents; therefore 013 clearance is not required under P.L.96-511.
Sincerely, Original signed by Robert L Tedesoo Robert L. Tedesco, Assistant Director for Licensing Division of Licensin9 l'

No.
Review Concern Submittal of Updated Construction Sequence Drawing (Identified 1
in Feb. 3-5 Audit and Feb. 26, 1982 Meeting).
Letter documenting actual work to be performed under Phase 2a 2.
(telephone record, March 8,1982, Par. 3).
Letter should provide coatitaent not to proceed with 2b until the ar,alyses using NRC recommended stiffness valves are completed and results reviewed by NRC Staff.
Update drawing of " Monitoring Matrix", No. C-1493(Q) that will 3.
include tolerance criteria (Telephone record, Mar. 8,1982, Par. 4.b).
CPC commitment to have 6 deep seated bench marks with instruments 4.
installed and operational before beginning Phase 2a work.
(Telephone record, March 8,1982, Par. 4.B and Par. 5).
