The five business days that decide how a tank lands
Under ORS 105.475, delivering the seller property disclosure statement starts a clock: the buyer has five business days to revoke the offer, with no penalty and a full return of their deposit. A heating oil tank that appears for the first time inside that window is the kind of surprise the revocation right exists for, because the buyer is suddenly holding an unpriced cost and an environmental question.
The same tank, disclosed as already decommissioned with the DEQ report attached, reads as a closed matter. Nothing about the tank changed. The timing and the paperwork did. That is the whole argument for raising it at the listing appointment rather than after an inspection finds a fill pipe.
Worth knowing before you advise a seller to tick "Unknown": the form asks about actual knowledge, and "Unknown" tends to move the question to the buyer rather than remove it.
The real timeline, so you can plan a closing around it
The dig is the short part. The lab and the filing are what set the calendar, and neither compresses on request.
| Stage | Typical duration | What it depends on |
|---|---|---|
| Site survey and written quote | Booked on request | Access to the property |
| Physical decommissioning on site | 1 to 2 days | A straightforward side-yard tank. Driveways, additions, and tight access run longer. |
| ORELAP lab soil analysis | 1 to 3 weeks | Sample prep, the run, and QC, against whatever queue the lab is holding |
| Decommissioning Report filed and registered with DEQ | 5 to 8 weeks end to end | Cannot start until soil results are back |
| If soil comes back contaminated | 1 to 6 months | Additional sampling, excavation and disposal, confirmation samples, a separate Cleanup Report, then a DEQ closure letter |
Some providers sell a paid rush lab turnaround when a deadline demands it. Nobody can file a Decommissioning Report before the soil results exist.
When the closing is tighter than the timeline
A 30-day escrow does not fit a 5 to 8 week decommissioning, and pretending otherwise is how a closing date slips. The workable arrangement is to complete the physical decommissioning and the inspection inside the window, write the decommissioning into the contract as a closing condition, and let the Decommissioning Report file shortly after closing. Most Salem-area lenders accept that rather than waiting on the filed report.
Say this early. A seller who hears it at the listing appointment has options. A seller who hears it on day 22 of a 30-day escrow has one.
What your client should walk away holding
Once the pit is backfilled there is nothing left to inspect, so from that point the only proof the job was done properly is paper. A future buyer cannot inspect a tank that is gone, a lender cannot lend against a verbal assurance, and an insurer will not take anyone's word for it.
- The Decommissioning Report, filed with the Oregon DEQ Heating Oil Tank program and registered in the DEQ database
- The ORELAP lab soil results the report is built on
- The City of Salem or Marion/Polk County permit final
- Confirmation the property now has an entry in the DEQ database
Keep the four together in one property file. Salem sees a lot of state-employee households and out-of-area relocations, and both tend to read property records closely.
Cost ranges you can quote before anyone has a quote
These are 2026 ranges for DEQ-licensed providers working the 97301 to 97309 corridor. They let you give a seller a realistic number at the kitchen table without committing anyone to a price.
| Scenario | Typical range |
|---|---|
| Underground tank, clean decommissioning, full removal | $1,400 to $3,500 |
| Underground tank, clean decommissioning, abandonment in place | $1,100 to $3,800 |
| Aboveground tank, exterior | $700 to $1,400 |
| Basement or crawl-space tank | $900 to $1,800 |
| Localized contamination adder | $3,500 to $12,000 |
| Full DEQ Cleanup Rule case | $15,000 to $80,000+ |
Most Salem-area decommissionings end with clean soil samples and no cleanup adder. Oregon has no reimbursement fund for residential heating oil cleanup, so a contamination case sits with the owner.
Send us an address and we will check the DEQ record
Before a listing goes live, the cheapest thing you can do is find out whether the property already has a decommissioning on file. We run the address against the Oregon DEQ Heating Oil Tank database and tell you what is there. There is no charge for this and it does not commit your client to anything.
One caveat we would rather you hear from us: the DEQ database only holds tanks that were formally decommissioned and reported. A tank abandoned quietly, or removed before the program existed, leaves no record at all. An empty result means unproven, not clear.
Working a tank into a listing
- 01
At the listing appointment
Send us the address. We check the DEQ record and come back with whether anything is on file, usually the same day.
- 02
Before the disclosure statement goes out
If there is a tank or a strong indication of one, we survey the property and issue a written fixed-price quote at no cost. Your seller then chooses whether to handle it pre-listing or price it in.
- 03
Through escrow
If the work runs alongside a live transaction, we tell you honestly whether the filed report can land before your closing date, and we send the document set to whoever you nominate.
