The EPA has issued 2015 New Underground Storage Tank Regulations and the 2015 state program approval regulation. The revisions strengthen the 1988 federal underground storage tank (UST) regulations by increasing emphasis on properly operating and maintaining UST equipment. The revisions will help prevent and detect UST releases, which are a leading source of groundwater contamination. The revisions will also help ensure all USTs in the United States, including those in Indian country, meet the same minimum standards. This is the first major revision to the federal UST regulations since 1988.
The 2015 regulation changes certain portions of the 1988 underground storage tank technical regulation in 40 CFR part 280. The changes establish federal requirements that are similar to key portions of the Energy Policy Act of 2005. In addition, EPA added new operation and maintenance requirements and addressed UST systems deferred in the 1988 UST regulation. The changes 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
- Adding requirements to ensure UST system compatibility before storing certain biofuel blends
- Removing past deferrals for emergency generator tanks, airport hydrant systems, and field-constructed tanks
- Updating codes of practice
- Making editorial and technical corrections
