EPA Updates UST Regulations After 27 Years

October 15, 2015

The U.S. EPA updated the 1988 underground storage tank (UST) regulations, which took effect Oct. 13. This interactive 10-question quiz by BLR Safety Blog will test how well you know these regulations. 

The 2015 UST 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. 

Key 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; and
  • Making editorial and technical corrections.
