Changes to the Underground Storage Tank Regulations        

GovDelivery logo


On Aug. 8, 2005, President George W. Bush signed the Energy Policy Act of 2005. Title XV, Subtitle B of this act (titled the Underground Storage Tank Compliance Act of 2005) contains amendments to Subtitle I of the Solid Waste Disposal Act, the original legislation that created the underground storage tank (UST) program. This law significantly affects federal and state underground storage tank programs, will require major changes to the programs and is aimed at reducing underground storage tank releases to our environment.

Missouri has already implemented the fuel delivery prohibition (“red tag”), new reporting requirements and now inspects facilities every three years.  Missouri is working to implement operator training and secondary containment (double-walled systems). 

While the department believes that our existing state program requiring financial responsibility for installers and manufacturers of underground storage tanks meets the requirements of the 2005 Energy Policy Act, we have been unable to demonstrate this to the satisfaction of U.S. Environmental Protection Agency (EPA).  As such, we are moving forward to publish state regulations requiring secondary containment for new UST systems.

If you have questions regarding these regulations, contact Heather Peters of the Hazardous Waste Program at 800-361-4827 or 573-522-5665 or by email.


The upcoming rulemaking will try to address three primary goals:

  1. Include state specific requirements- resolve issues with 2011 rulemaking, address problems seen in Missouri, clarify vague or ambiguous language.
  2. Enact the secondary containment (double-walled) requirements, as mandated by EPA.
  3. Include the new EPA regulations, when finalized (expected Fall 2014).

UST Operator Training in Missouri

The Petroleum Storage Tank Insurance Fund Board of Trustees is in the process of creating an on-line operator training program, with a “test only” option. This program will be free to Missouri operators. The fund hopes to unveil this program in 2014. The fund will also be developing regulations to enact the operator training program. While Missouri did not meet the Aug. 8, 2012, deadline to have operators trained, Missouri has state program approval, and has been communicating with the EPA on this matter.  Therefore, once operator training is established in Missouri, operators will be expected to comply with the Missouri requirements and deadlines.    

After making the training/testing program available, Missouri plans to move forward to enact regulations that may require:

Stay tuned for further developments!
