replaced. Manufacturers now offer testable over;ll
prevention valves that allow positive shutoff of product
delivery, and testing can be done without removing
over;ll prevention valves from tanks. Testing can be
completed in 60 seconds rather than 60 minutes.
• Testing dispenser sumps that are buried deep underground requires a lot of water and time. Today,
manufacturers offer shallow-bury dispenser sumps that
allow for quick, easy testing and access to all components from grade level. These next-generation sumps
can be ordered with integrated electrical junction
boxes that eliminate the need to drill holes and install
conduit entry ;ttings.
• Fiberglass tank sumps with smooth, consistent wall
surfaces inside and out provide for seal integrity for
future entry ;tting testing. They also create a clean, dry
environment for future maintenance and inspection.
• Next-generation multiports provide access and containment of riser connections to tanks and have watertight
sump inspection ports and easy access to testable
over;ll prevention valves. Lightweight composite
covers allow for easy, safe removal for inspections. All-composite construction ensures no corrosion.
UST systems and equipment must be brought into compliance and will need to be inspected and tested repeatedly.
Out;tting fueling sites with the most modern UST equipment and systems is a good solution.
Manufacturers of these UST components have responded
with next-generation technologies that elevate the performance of sumps, spill buckets and over;ll prevention valves.
The bene;ts to site operators, customers and the environment include cost-effectiveness, time-savings, reliability and
environmentally safe performance.

containment vessels. If these spill buckets need to be replaced
in the future, the double-walled design allows replacement
without breaking concrete. Electronic sensors can be added to
continuously monitor interstitial spaces and eliminate the need
to test every three years. New spill bucket designs protect fuel
quality while minimizing cleanup costs and corrosion of the ;ll
and vapor-return riser connections and components.
• Traditionally, when over;ll prevention valves needed to be
tested, contractors had to go to the sites to shut down the
USTs and pull the valves from the tanks. Valve removal
was dif;cult, and valves often got damaged and had to be
