Buried Oil Tank Locating: what you need to know
A buried heating oil tank usually leaves clues above ground, if you know where to look. DEQ’s homeowner guidance on heating oil tanks describes the typical tank as sitting within two feet of the house it served and about two feet down, close to where the furnace sits inside. The fill pipe is often lost under grass or a flowerbed, but the vent pipe, 1.25 to 1.5 inches across and running two to eight feet up the side of the house with a small cap, is almost always still visible.
A vent pipe alone does not tell you whether the tank is still in the ground, and that is the question a buyer, seller or lender needs answered. Under ORS 466.878, an emptied tank that was never decommissioned has to keep its vent line in place, so the pipe on your wall may belong to a tank that is empty but still buried. A tank someone removed decades ago may have left its pipes behind as well.
We sweep the property to settle it. A grid sweep with a large-metal detector finds the obvious targets, a magnetic locator narrows them down, and a probe confirms the top of the tank where it is safe to do so. On a lot with rebar, buried pipes or a slab in the way, ground-penetrating radar can help, although it struggles in wet clay. You get a written result stating what was found, where, and what could not be ruled out, and if a tank turns up, the underground oil tank removal quote starts from real measurements.
More of these questions are coming up as Salem homes leave oil. Oregon’s Heat Pump Purchase Program opened in June 2025 with incentives of up to $2,000 per installation, and every conversion leaves an old tank behind that the next buyer will want accounted for.
Benefits of Buried Oil Tank Locating
More than one tool
Metal detection, a magnetic locator and a probe, with ground-penetrating radar where concrete or buried metal gets in the way. A single tool can miss a tank or mistake a pipe for one.
A written result
What was found, where it is, and what could not be ruled out, in a short report an agent, lender or title officer can read without translation.
Measurements for the quote
The location, rough size and depth of any tank we find, so a removal or decommissioning quote is based on the real job rather than a guess.
Records checked alongside
We check DEQ decommissioning and leak records for the address too, since a tank that was properly closed years ago may still be in the ground with paperwork to prove it.
Is Buried Oil Tank Locating the right service for your situation?
A tank locate is worth booking when:
- There is an old fill pipe in a flowerbed or lawn, or a capped vent pipe up the side of the house.
- You are buying a Salem home that once heated with oil and the seller answered “unknown” on the tank question.
- You are selling and want the tank question settled before a buyer’s inspector raises it.
- Oil lines come through the foundation or basement wall and there is no tank in sight.
- The home was converted to gas or a heat pump and nobody knows what happened to the old tank.
How the process works
Booking and clues
Tell us the address, the age of the house and anything you have seen: pipes, old oil lines, where the furnace sits. That tells us where to start.
Records check
We look for a DEQ decommissioning record or leak file for the address before the visit.
On-site sweep
A grid sweep of the likely area around the house, following up every target until it is explained or confirmed.
Written result
A short report of what was found, where, and what could not be ruled out, usually the same day.
What buried oil tank locating costs in Salem
Locating is a small job with published prices. Your quote depends on lot size and how much buried metal the sweep has to work through.
| Scenario | Salem range | What is included |
|---|---|---|
| Tank search, DEQ estimate | $100 to $200 | DEQ’s typical figure for hiring someone to look for a tank |
| Published Portland-area sweep prices | $125 to $195 | Two published prices from Portland-area providers |
| Soil test beside a tank we find | $200 to $300 | DEQ’s estimate for a basic test to see whether it leaked |
Ground-penetrating radar, large or wooded lots, and heavy interference from buried metal add time. Removal or decommissioning of any tank we find is quoted separately.
