Response
See sub response. Recommend closure of this CR. There are no other open CAs for this CR.
Subresponse :
There has been previous documentations of the noted conditions in the manholes as found in past PMs. The responses to the past CRs include some repairs to the existing supports and pumping out of water. However, dewatering PM frequencies were never adjusted and the degraded supports have not been replaced. In the current conditions, there is no challenge to cable integrity since the cable is in supported condition. The following corrective actions have been performed 1 are recommended to achieve acceptable conditions:
- 1. Dewatering PM frequencies have been adjusted to accommodate water levels according to history:
Manhole 31 PM frequency adjusted to 1 month Manhole 31A PM frequency adjusted to 2 month Manhole 3lB PM frequency adjusted to 2 month
- 2. The following work orders have been generated to correct 1 repair degraded conditions found in the manholes:
Manhole 31 - 274954 Manhole 31A - 274955 Manhole 3lB - 274958 Closure Comments:
