The procedures to remove an underground storage tank are regulated!

Whether you’re planning to remove a single underground storage tank or a multi-tank system, you’ll need to obtain necessary permits from the New York State Department of Environmental Conservation (or your state’s equivalent agency). Some municipalities such as New York City have additional rules and may require additional permits, too.


Be sure to call Dig NY or your local utility locator service before any digging begins, to avoid damage that will cost you more and delay your tank removal project.

There are direct costs associated with underground storage tank removal.

These procedures are designed to ensure that once your underground storage tank is removed, no contamination is left behind:

  • Empty and clean the tank.
  • Remove the tank.
  • Inspect it for any signs of damage that could have caused a leak.
  • Visually inspect the surrounding area for any signs of a release.
  • Take soil samples for testing and analysis.

If no contamination is found after your underground storage tank is removed, the excavation can be filled and the area can be resurfaced or landscaped. A report documenting the tank removal activities and sampling results should be maintained in your files. If problems are detected, you’ll need to prepare a remediation plan.

This isn’t a job for your employees.
