A step-by-step checklist for decommissioning a Salem oil tank

Part of: Salem Oil Tank Removal Permits: Who Pulls What, and When (2026)

Most of a decommissioning is handled by your licensed provider, but knowing the full sequence helps you confirm nothing is being skipped and lets you keep a complete property file at the end. This is the checklist version of the Salem removal pillar: each step in order, with the documents you should end up holding.

Before the work

The setup steps decide whether the job goes smoothly and whether it closes cleanly.

  • 011. Confirm the tank exists and where it is. If you are not certain, a locate scan settles it. See finding a buried Salem tank.
  • 022. Verify your provider's DEQ license. Number in writing, checked against the DEQ list.
  • 033. Get a fixed-price quote with a written sampling plan. Number of samples, lab, analyte panel, turnaround.
  • 044. Confirm the permit jurisdiction. City of Salem, Marion, or Polk County. The provider pulls it.
  • 055. Decide removal vs abandonment in place. Access usually decides it. See abandon vs remove.

During the work

The on-site day or two. You do not need to supervise, but you should know what each step is for.

  • 016. 811 utility locate down before digging. Marks for gas, water, power, telecom.
  • 027. Pump and clean. Residual fuel and sludge to a vacuum truck; tank verified vapor-free.
  • 038. Remove or fill. Cut and lift, or pump-clean-fill for abandonment.
  • 049. Soil samples pulled. Per the plan, with a location diagram. This is the step that protects you at resale.
  • 0510. Backfill and inspection. Clean compacted fill; the permit office inspects and signs off.

After the work, the part that matters at resale

The job is not done when the hole is filled. The closeout is the documentation.

  • 0111. Decommissioning Report filed with DEQ. Provider compiles lab results, photos, manifests, and certification, and files within sixty days.
  • 0212. File your copies. Keep the finalised permit and the Decommissioning Report together. This pair is what a future buyer's lender or title company will ask for.

Tip

If you only keep one thing from this list, keep the Decommissioning Report with the property records. Years from now, when you sell, it is the single document that proves the tank was handled correctly, and producing it on request is the difference between a smooth closing and a scramble.

Checklist: Common Questions

What is the most-skipped step on this checklist?
Soil sampling and the filed Decommissioning Report. A lowball or unlicensed job often digs the tank out and stops, with no samples and no Report. That leaves no DEQ record, which surfaces as a problem when you sell. Those two steps are the whole point of doing it properly.
Do I need to do any of this myself, or does the contractor?
The licensed provider handles the permit, the work, the sampling, and the filing. Your job is to verify the license up front, choose removal or abandonment, and keep the finalised permit and Decommissioning Report in your records afterward.
How do I know which steps apply to a basement tank?
A basement or crawl-space tank skips the excavation steps but still needs professional pumping, cleaning, cutting, and disposal documentation. It is technically an aboveground tank under the rules, so a full DEQ Decommissioning Report is not always mandatory, but most lenders still want proof of licensed work.
Can I use this checklist outside Salem?
The sequence is the same statewide because the DEQ rules are statewide; only the permit office changes by jurisdiction. This version names the Salem-area permit authorities (City of Salem, Marion, Polk), but the twelve steps apply across Oregon.
