EPA Releases Report on Corrosion Risks in Underground Storage Tanks

U.S. Environmental Protection Agency, July 26, 2016

The United States Environmental Protection Agency (EPA) has released a report from its recent examination of 42 operational underground storage tank (UST) systems storing diesel fuel across the country. In the July 2016 report, the EPA finds that there was a significant prevalence of corrosion inside these tanks and recommends that all owners of UST systems storing diesel fuel conduct a visual inspection by checking in their filters and inside UST system access points, even if they have not seen symptoms in the filter; severe corrosion may already be established before symptoms appear in the fuel filter and an owner becomes aware of a severe corrosion issue.

Furthermore, the EPA recommends that owners also contact UST servicing companies to further evaluate the extent of corrosion inside tanks. If owners or the servicing company finds corrosion, equipment should be repaired or replaced as necessary to ensure proper functionality. Until the exact cause of corrosion is determined and a long term solution is identified, EPA recommends owners refer to several industry documents that suggest currently available best practices, technologies, or treatments available to minimize the risk of release of diesel fuel from tanks.
