Revisions to Underground Storage Tank Regulation

Updated: Aug 28, 2023

In late June, the Environmental Protection Agency announced the publication of a final rule regarding underground storage tank (UST) requirements. The goal of the rule is to improve leak prevention and detection, reducing groundwater contamination.

“These changes will better protect people’s health and benefit the environment in communities across the country by improving prevention and detection of underground storage tank releases,” said Mathy Stanislaus, assistant administrator of EPA’s Office of Solid Waste and Emergency Response. “Extensive and meaningful collaboration with our underground storage tank partners and stakeholders was vital to the development of the new regulations. The revised requirements will also help ensure consistency in implementing the tanks program among states and on tribal lands,” Stanislaus added.

The EPA says the revised rule will strengthen existing requirements and ensure that all USTs in the United States are required to meet the same release protection standards. The revisions include:

  • adding secondary containment requirements for new and replaced tanks and piping

  • adding operator training requirements

  • adding periodic operation and maintenance requirements for UST systems

  • removing past deferrals for emergency generator tanks, airport hydrant systems, and field-constructed tanks

  • adding new release prevention and detection technologies

  • updating codes of practice

  • updating state program approval requirements to incorporate these new changes
