Secondary Containment

California regulations SB989 require secondary containment testing at all new sites upon installation, within 6 months after installation and every 36 months thereafter. All existing sites were required to be tested prior to December 31, 2002 and every 36 months since that date.

Secondary containment systems act as the failsafe for underground storage tanks in the event a release occurs. Leaking pipes, dispenser pans, spill buckets, and sumps could cause a product to be released into the environment; this causes major problems for the UST owner from regulatory agencies. Testing of the secondary containment ensures that if a release occurs, it will be contained and the UST owner will remain in compliance.

Spill Bucket Testing

Spill containment buckets keep petroleum products from being released into the environment if a spill or overflow occurs. Weathering effects, such as, corrosion can cause spill containment buckets to degrade to the point that leaks may occur.

If a spill bucket is found to be leaking, our technicians can repair or replace it and test the system again, saving you time and money by not requiring a return trip.

Monitoring Systems Certifications

All monitoring systems in California are required to be certified annually. Our experienced technicians can certify your system and have you back up and running. We also provide same day repair if needed.

Helium Leak Locating

In the event of a leak, our technicians will be able to locate it utilizing helium tracing technology. Our trained staff is capable of repairing the leak in a timely manner, minimizing down time.
