Underground Storage Tank Regulations for Operation, Temporary Closure and Permanent Closure

In 1985, the Environmental Protection Agency created the Office of Underground Storage Tanks to carry out a Congressional mandate to develop and implement a regulatory program for underground storage tank, or UST, systems. In 1989, Missouri enacted statutes to create the Missouri Department of Natural Resource’s Underground Storage Tank regulations and program. Since 1989, the regulations had not been substantially changed or updated to reflect the many changes and improvements to underground storage tanks, piping, release detection methods and other equipment.

On August 18, 2011, the Hazardous Waste Management Commission voted to adopt the final order of rulemaking that would update Missouri's underground storage tank regulations. While there were some minor changes and clarifications, there were only a few significant changes from the May 2011 Missouri Register publication:

The Final Orders of Rulemaking for these regulations were published in the Nov. 1 Missouri Register.
