Heating Oil Tank Program

The current Heating Oil Tank Program started on March 15, 2000. This program allows third party certification of cleanups and decommissionings of heating oil tanks by DEQ licensed service providers. When a licensed contractor completes a cleanup or decommissioning, the company submits a certification to DEQ. DEQ will then issue a letter to the tank owner registering the contractor's certification. The combination of the contractor's certification and DEQ's registration is equivalent to the "No Further Action" letter that the DEQ used to issue.

The HOT Program handles issues related to cleanup of leaks from heating oil tanks, contractors working on heating oil tanks, and the voluntary decommissioning of heating oil tanks.

If you are an existing or potential HOT homeowner or a realtor and have questions like:

  • Is there or was there a HOT on this property?
  • I'm selling property with an existing HOT, what are my responsibilities?
  • I'm selling property with an abandoned HOT, what are my responsibilities?
  • Who can I hire to remove a HOT?
  • Can I do my own cleanup of a HOT?

If you are an existing or potential contractor and have questions like:

  • What are the current requirements for contractors working on HOTs?
  • What are the service provider license renewal requirements?
  • Does DEQ have an example of a model HOT cleanup report?
  • Where can I obtain copies of the laws and rules on HOT cleanups?
  • What are the licensing requirements for becoming a HOT Tank Services Supervisor?
  • Where can I take the exam to become a HOT Tank Services Supervisor?
