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.
