Approach To and Status Of Proposed Resolution Bechtel Engineering has contacted the vendor (Cooper Energy
[
Services), letter B/CES-E-52621, dated December. 31, 1985, requesting concurrence with the reportability evaluation and their proposed corrective action. -A response by January 17, 1986 has been requested.
