Oregon's Underground Storage Tank Program is part of the DEQ's Land Quality 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.

Notice: The Environmental Quality Commission adopted the proposed underground storage tank rules at their May 10, 2018 meeting. The commission is a five-member citizen panel appointed by the governor serving as DEQ’s policy and rulemaking board. The rules became effective on June 1, 2018 and apply to all owners of regulated USTs in Oregon.
