UST Removal and Disposal Stockton Lake
Contractor Questions: 12-3-2024
1. What is the distance from existing grade to top of tanks?
Answer: Approximately 4 to 5 feet.
2. SOW Item 1.8 states Contractor shall remove tanks, piping, meters, pumps, etc. However, Item 3.1: Gov’t Furnished Services states Gov’t will provide removal of fuel island pumps, vent pipes, backfill hole & resurface concrete.
Answer: Amended to change 3.1 Gov’t Furnished Services to NONE.
3. Who is responsible to drain-up and gas-free the piping? If by Contractor, what volume of liquids can we expect to handle?
Answer: The Contractor. The tanks were emptied to RCRA less than 1”, so approximately 5-10 gallons of liquid in each tank.
4. Who is responsible to de-energize all power, controls and cathodic protection?
Answer: The Cathodic Protection has already been disconnected from power. As for the utilities in the area, the government will be responsible for turning the power off and then back on in intervals for agreed amounts of time during excavation for operation purposes. Power intervals should be as follows: four (4) hours off, one (1) to two (2) hours on, then four (4) hours off again, and so on. The Contractor will be responsible for the locating of all utilities on Government property near the excavation site.
SITE VISIT QUESTIONS: 12-4-2024

Answer: No compaction test required. We trust and expect the contractor to mechanically compact to the UFC standard for being topped with a concrete pad. There will be contract oversight from the Contract Officer Representative and the Maintenance Lead.
6. Will there be additional Contract Line Items for any contaminated soil?
Answer: No, there is only one contract line item for the job as a whole. The Veeder Root Monitoring System has never indicated any leakage nor has any seepage been observed at the site; However, it’s always best to err on the side of caution and anticipate or account for some contamination to ensure you capture any potential expenses.
