1.0 UNDERGROUND STORAGE TANK PRODUCT PIPING

REMOVAL & REPLACEMENT

Provide all labor, materials, equipment and incidentals necessary to remove and replace all underground product piping (both unleaded gasoline and diesel) from two underground storage tanks (UST) to associated aboveground dispensers.

2.0 LOCATION

Montana Department of Transportation (MDT) – Helena Headquarters 2701 Prospect Avenue Helena, MT 59620 DEQ Facility ID No. 25-06849

3.0 BACKGROUND

The Gilbarco Veeder Root TLS 350 automatic tank gauging (ATG) identified an unleaded (UL) line leak on September 16, 2025. The product piping is monitored for leaks using pressurized line leak detectors (PLLD) programmed to shut down dispensing capabilities at the detection of a leak. It was determined that the connection of the piping to the submersible fuel pump assembly had failed and was leaking. Leaked fuel was contained within the submersible pump turbine (STP) sump located about the UST.

The fueling system at the location consists of one (1), 12,000-gallon UL UST and one (1) 12,000-gallon diesel UST. Both tanks are constructed with double-walled fiberglass reinforce plastic (FRP). Both the UL and diesel project piping is double-wall flexible plastic manufactured by Total Containment. Approximately 100-120 feet of product piping serve two (2) aboveground dispenser islands, each with an UL and diesel dispenser totaling four (4) dispensers. Each island is complete with under dispenser sumps.
