What usually shows up first
Most Salem-area tanks announce themselves through leftovers rather than through the tank itself. On a pre-1980 build with no record of a conversion, any one of these is worth a line in the report.
- A fill pipe or vent stub in a side yard, flower bed, or against the foundation, sometimes cut flush and painted over
- Capped copper supply lines running through a crawl space or basement wall to nothing
- An abandoned flue or a chimney thimble with no appliance on it
- A furnace or water heater that is obviously newer than the house, with no permit history for the changeover
- A rectangular depression, a patch of grass that dries differently, or settled ground in an otherwise flat yard
Most 1940s to 1960s residential tanks in Salem sit under 2 to 4 feet of cover, with the top of the tank 24 to 36 inches below grade.
Why a visual indicator is not a located tank
A fill pipe tells you there was oil heat. It does not tell you whether the tank is still down there, what size it is, where it actually sits relative to the pipe, or what condition it is in. Fill lines run, tanks get pulled without the pipe being removed, and a pipe against the north wall does not mean the tank is against the north wall.
Confirming presence, size, and position takes a probe and a magnetometer pass, which is outside a visual inspection and outside most inspectors' insurance. Reporting the indicator and recommending a locate keeps the finding accurate and keeps the call about what is underground with the person licensed to make it.
What a locate actually resolves
A tank sweep answers the three questions your report cannot: whether a tank is present, how big it is, and where it sits. That is what the buyer needs before the inspection period runs out, because the decision between removal and decommissioning in place, and the cost of either, follows from those three answers.
We also run the address against the Oregon DEQ Heating Oil Tank database at no charge. Worth knowing what that result is worth: the database only holds tanks that were formally decommissioned and reported, so an empty result means unproven rather than clear. A tank abandoned quietly, or removed before the program existed, leaves no record.
Timelines your client will ask you about
The question that follows a flagged fill pipe is always some version of "can this be sorted before we close". The honest answer is that the dig is fast and the paperwork is not.
- A straightforward side-yard tank is pumped, cleaned, cut, lifted, sampled, and backfilled in one to two days
- ORELAP lab soil analysis typically takes one to three weeks
- A filed and registered Decommissioning Report runs five to eight weeks end to end
- If soil comes back contaminated, budget one to six months for the cleanup case and the DEQ closure letter
Handing over a suspected tank
- 01
Report what you saw
Describe the indicator and recommend a locate. You do not need to characterize the tank, and you are better off not doing so.
- 02
Send us the address
We check the DEQ record at no charge and come back with what is on file, which sometimes resolves the question on the spot.
- 03
We take it from there
If a locate is needed we book it, and if a tank is confirmed we issue a written fixed-price quote. Your client hears the cost and the timeline from us, not a guess from the inspection report.
