The EPA strongly recommends that gas station and fleet facility owners regularly inspect their above-ground fuel storage tanks. The practice helps prevent leaks and proactively addresses contamination issues.
What steps are involved in an above-ground fuel storage tank inspection and how often should owners perform this inspection? This blog provides a quick overview of the basic details of one. Comprehensive and tailored guidance can be obtained from a local implementing agency.
Above-Ground fuel storage tank inspection
Two types of tests are performed during an above-ground fuel storage tank inspection process: a fuel sample test and an integrity test.
In the fuel sample test, the facility owner checks the fuel stored inside the storage tank for traces of water or microbial contamination. Particular signs to look out for include:
- Cloudy appearance
- Sludge deposits
- Unpleasant smell
The integrity test involves a visual examination of the tank system and its foundation. The owner must look for signs of corrosion, fuel accumulation, discharge, or general deterioration – on, in, and around the tank system. In case a damaged component or leak is detected, a repair technician should be immediately consulted for help.
As for how often tank inspections should be performed, there are no specific industry guidelines or standards set by the Environmental Protection Agency (EPA) in this regard. However, performing an inspection once a month is generally considered good practice.
Furthermore, all inspections should only be performed by trained and certified tank inspectors to ensure a robust and thorough inspection process.
Also, facility owners should keep the validated tank inspection records for at least three years.
Incorporating fuel tank inspections into your routine maintenance plans can prevent dangerous and costly leaks.
