Heating Oil Tank Program

DEQ has relocated the Portland Heating Oil Tank office from 2020 SW Fourth Avenue, Suite 400 to 700 NE Multnomah Street, Suite 600, Portland, 97232.
Call 503-229-6170 for more information.

The current HOT 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 the Department. The Department 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.
