Underground Storage Tank (UST) Permits

Environmental Services maintains a data base of permits for underground, and aboveground, heating oil storage tanks in some parts of Portland. The information is available at http://www.portlandmaps.com

Enter an address and press the search button to view information about the property at that address. If the navigation bar at the top of the screen lists a "Storage Tank" option, click on it to see a list of nearby properties with storage tank permits. Click on any property in the list to view a photo of the actual permit, which you can download, print or email.

About UST Permits

The Portland Fire Bureau issued these permits between 1936 and 1990 when it was the Fire Bureau's job to inspect installation or renovation of aboveground and underground residential heating oil storage tanks. 

Many neighborhoods within the City of Portland today were not inside the city limits when tanks were installed. Environmental Services does not have permits for those addresses, which are generally east of 92nd Avenue, south of SE Foster Road, north of Columbia Boulevard, and in Maywood Park and Rose City. 

Permits for some addresses may not be available because they were lost or the owner never filed one. You should always have a tank locate performed in addition to searching this database. You can download a list of tank companies licensed by the Oregon Department of Environmental Quality, and find other information about underground storage tanks, at www.deq.state.or.us/lq/tanks/ust/index.htm.

Permits were issued for installation and renovation, not for decommissioning and removal. The City has never required permits to decommission or remove a tank on private property. If your tank is under the street or sidewalk, it is in the public right-of-way and you will need a street or sidewalk opening permit from the Portland Office of Transportation (PDOT) to access the tank. If the tank has leaked, and it was reported to the DEQ, you can access the file at the link above. Otherwise, there are no records for clean tank sites.
