Dear Mr. Bingham:

-lj!"

msw Please find attached a list of 480V MCC equipment located at the Pahy"j Verde site having Size 2 Starters containing normally open add-on ~

interlocks that potentially may malfunction.

Replacement interlocks are presently being certified at our Mebane Manufacturing Facility. Howevcr, before we send these replacements to the site, we will need the necessary Bechtel identification (i.e.,

DCP #, NCR #, etc.), so that they can be received at the Bechtel Warehouse.

Please provide me with this information so that we may proceed with shipment.

In addition, General Electric Engineering Services will provide technical direction to direct Bechtel craf t labor in the interlock changeout and therefore, I would appreciate knowing who to contact to schedule the work.

Your assistance in providing me with the necessary information is greatly appreciated.

Thank you.
