- Fred, Please modify request 5 of the inaccessible cables question as shown below.
- Thanks, Lisa
- 5. LRA Section B.1.19, Non-EQ Inaccessible Medium Voltage Cable, (Attachment 1, page 9) states that additional operational inspections will be performed to verify drainage systems are functional prior to predicted heavy rains or flooding events such as hurricanes.
Although operational inspections are stated to be performed prior to predicted heavy rains or flooding events it is not clear to the staff that all in-scope manholes are equipped with dewatering/drainage systems such as sump pumps. Confirm that all in-scope manholes are equipped with dewatering/systems such as sump pumps.
If in-scope manholes are not equipped with dewatering/drainage systems, explain how these manholes are inspected for event driven occurrences (heavy rain or floods, etc.). In addition, for in-scope manholes equipped with dewatering/drainage systems, explain how these manholes are inspected subsequent to event driven occurrences to ensure that inaccessible power cables are not exposed to significant moisture.
For manholes equipped with dewatering/drainage systems such as sump pumps, desribe the surveillance and functional testing performed on these systems such that associated in-scope inaccessible power cables, in combination with manhole inspections, are not exposed to significant moisture.
