Underground Storage Tank Program

30th Anniversary of the Underground Storage Tank Program

Nov. 8, 2014 marked 30 years since Congress created the national underground storage tank program. In 1985 the Oregon Legislature decided to partner with the U.S. Environmental Protection Agency to implement the UST Program in the state. EPA and its state partners work to prevent releases, detect leaks early and clean up leaks when they do occur. To view a summary of the UST Program accomplishments over the past 30 years, see Quick Facts on Underground Storage Tanks: U.S. and Oregon, 1984 to 2014.

Oregon's Underground Storage Tank Program is part of the DEQ's Operations Division. The UST Program handles issues related to tank registration and operating certificates; installation, operation and removal of USTs; cleanup of soil and groundwater contamination from petroleum leaks; training of system operators; financial liability protection for future leaks, licensing of contractors working on USTs and enforcement of state UST rules.
