Underground Storage Tanks (USTs)
The regulation of Underground Storage Tank (UST)  was created in 1985 to regulate the installation and operation of underground petroleum/chemical storage tanks. The goal of the Program is to protect human health and the environment by preventing releases of liquid petroleum and hazardous substances from storage tank systems. The release of these regulated products into the environment threatens groundwater resources and can cause explosive vapors to seep into confined spaces and occupied dwellings.

Proposed Revision Underground Storage Tank Rules 2020

Comments on the proposed rules will be accepted until May 8, 2020. Please send your comments to

The Vermont Department of Environmental Conservation is proposing some revisions to the Underground Storage Tank Rules.  The primary changes are as follows:

  • Eliminate the requirement that permit renewals and changes of ownership must be posted on the Environmental Notice Bulletin (ENB) for 2 weeks before a permit can be issued 
  • Change the definitions of “Minor Alteration” and “Substantial Alteration” so that replacement of sumps, spill buckets, and piping that can be pulled through an existing chase will not require a construction permit.

There have been several instances in which a facility with underground tanks has changed hands but a permit to operate the UST system to the new owner was not issued quickly because the new permit had to be posted on the ENB.  New owners were not to be able to operate the UST(s) while the draft permit was on the ENB.  With the upcoming deadline of September 1, 2020 for testing sumps, spill buckets, and overfill prevention devices, it is expected that many tank owners will need to replace or retrofit these devices.  Under the current rules, tank owners will have to apply for a construction permit, and the draft permit has to be posted on the ENB for two weeks.  The proposed changes to the rules will allow this work to begin immediately, with a simple notification to the UST program.

Aboveground Storage Tanks (ASTs)
Regulation of ASTs by the Agency of Natural Resources began in 2011 as a way to try and reduce the number of releases from ASTs (mostly home heating tanks). Reducing the number of releases reduces the threat and impact of petroleum products on human health and the environment, and also helps limit liability for cleanup of uninsured releases to the Petroleum Cleanup Fund.
