Posted 12/07/15 - Thank you to everyone who participated in the UST Leak survey. Here are some general conclusions from the UST Leak Survey Results 2015:

UST professionals identified the main leak problem areas of the UST system as:

  1. inside dispenser covers (unions, fittings, meters) are a main source of leaks,
  2. followed by spill buckets and
  3. STP sumps. Problems within the sumps and UDCs stem from flex connectors, functional element, sump integrity and penetrations to the sump.

Flexible sump boots and seals appear also as a problem for owners/operators and installers. They are not standing up to vapors and long-term use. Part of the problem is angled entry for piping and conduit. Split boots are an option for replacement. This could be a time and money saver for installers/owners and operators, and it looks like they do the job. Check out Bravo, Franklin Fueling and OPW presentations.

A spill bucket’s life in Iowa is about 5-10 years. There is a significant advantage to double wall spill buckets when it comes to replacement and testing. Cost is a factor, however. There are single wall spill buckets available that can be replaced fairly easily without breaking concrete. Another option is to install the spill bucket within a sump, which like the double wall spill bucket, offers double protection against spills during transfers.

Flex connectors in the UDC and tank top sumps continue to be a source of leaks, likely due to the angles at which they are installed. Flex connectors are not intended to correct offset connections. There is a good reason some companies allow no bend in their flex connectors, they should merely absorb shock.

New fuels are a serious to very serious problem in Iowa. Problems from phase separation to external corrosion in STP sumps are not uncommon.

Secondary containment together with continuous electronic monitoring have been resounding successes in preventing releases according to survey results. Operator training also scored high in preventing releases and making the public safer—but it must be improved. One person commented that operator training is more effective in containing, rather than preventing releases. We can include annual refresher training for operators to make the program more effective. High operator turnover is seen as barrier to improving training.

UST professionals reported they do not often run into installation errors. When they do they find, severe line/conduit entry angles or improper entry boot installs, penetrations not properly sealed, sump deflection, settling concrete. In general, these problems are seen mostly on older systems.

When asked what the weakest link in our UST systems is, the answers were, not surprisingly: single wall tanks and piping, lack of routine inspections of dispensers, and training at the fill and delivery ends of the system.
