11/17 have greater than 100K gallons storage tanks.
Inspection is required.
Brunswick - Did do a full tank inspection with UT. brought in 20" Tank as temporary storage. Had to have adequate storage tank full of water. After completed some sand blasting, had through wall holes. Do not do during winter. Ended up with a 3 week evolution turning into 5 months.
Concern about water under tank and over concrete slab?
Put in a liner was cheaper than paint.
5 year inspection schedule.
Schedule away from winter months as well as outages.
