Getting Your USTs Winter Ready

UST SystemFall is officially here, and that means the holidays – and colder weather – are right around the corner. Before those freezing temperatures finally arrive, it’s important that all underground storage tank owners take the time to proactively perform tests. Here are a few things to inspect before frost and snow hit the ground:
  • Electrical Wiring
Excess moisture in your electrical conduits can freeze during the winter, so it’s important to have your electrical wiring components inspected and if necessary, fixed or replaced, to avoid water accumulating as the result of open junction boxes and faulty seal offs. Probes, sensors, electronic line leak detectors and submersible pumps all can be affected by water freezing in your wiring, and expensive compliance issues may result.
  • Tank Tightness
Water can enter your tank through tank top fittings such as fill port risers, vapor recovery risers, ATG risers or submersible pump risers. Sometimes the threads of these risers can crack and allow water to seep into your tank. Before the ground begins to freeze and thaw – causing extra ground movement – it’s important to inspect the tightness and condition of these parts before you have an expensive water leak on your hands.
  • Pipe Conditions
Old or faulty pipes are often more susceptible to cracks, breaks and joint failures during the cold winter months as the ground continually freezes and then thaws. Often times, your leak detection devices and alarms can signal a problem well before it becomes a compliance issue. Be sure to have your pipes regularly inspected, as mandated by compliance standards, and take the extra time to check your line and leak detection devices during the months prior to the winter season.
  • Sump Performance
Your tank’s sumps keep unwanted liquid away from key components of your tank. During the winter, water can freeze in your spill buckets, contained dispenser sumps and contained submersible pump sumps and cause damage to your piping components, flex connectors, electrical wiring and leak detectors. Ice in your sumps can eventually allow excess water to enter the sumps and your piping penetration boots can be damaged. If your piping penetration boots are damaged, they may no longer be liquid tight, which is a compliance violation. Sump inspections prior to winter are the best way to avoid these problems. Regular, monthly inspections throughout the winter months are recommended.

By being proactive in your tank inspections, you can often times avoid larger, more expensive problems, down the road! So before winter conditions hit, make sure to schedule those check-ups. Interested in learning more about our UST services? Please contact us!
