PHILADELPHIA — Through a settlement with the Environmental Protection Agency (EPA), the U.S. Postal Service (USPS) has certified that five of its facilities in Virginia are currently in compliance with federal and state underground storage tank (UST) regulations.

As part of this certification, USPS has corrected violations associated with its failure to conduct release detection testing; line leak detector testing; a line tightness test; and failure to investigate/report a suspected release. The USPS will also pay a civil penalty of $55,258.

With millions of gallons of petroleum products and hazardous substances stored in USTs throughout the U.S., leaking tanks are a major source of soil and groundwater contamination.

Federal and state UST regulations are designed to reduce the risk of underground leaks thus minimizing environmental harm and avoiding the costs of major cleanups.
