Heating Oil Tank Data

DEQ maintains an environmental data management system known as Your DEQ Online. Your DEQ Online tracks Heating Oil Tank site in Oregon. Data in Your DEQ Online is "working information" used by DEQ. 

Please note that:

  • YDO Public Project Records Is where you go to find information on a heating oil tank leak.
  • YDO Permit Licensing Certification is where you go to find heating oil tank clean decommissioning information.
  • Information found in YDO is not comprehensive for old projects, there may be older records in a physical file.
  • Some information in Your DEQ Online may be unconfirmed, outdated, or incomplete.
  • Information in Your DEQ Online is subject to change at any time. 

If the heating oil tank project started after April 3, 2024 the majority of the records will be in Your DEQ Online Public Records portal

If the heating oil tank project started before April 3, 2024, additional records may not be online. If you don't find what you need online, please submit a Public Records Request.

Specific instructions on how to search Your DEQ Online public records can be found on our User Guides and Program Resources Page
