Oil Tank Removal in Minnesota: MPCA Rules, Petrofund & Real Cost
What a buried heating oil tank actually costs to remove in Minnesota, what the state’s Petrofund will and won’t pay for, and why so many Twin Cities homes still have one in the yard.
Quick Answer
A clean underground oil tank removal in Minnesota costs $1,800–$3,500; basement and above-ground tanks run $600–$1,500. A registered closure contractor pulls the local permit, excavates, samples the soil, and files closure paperwork. If the samples come back dirty, that’s a separate remediation cost — and it’s the point where Minnesota’s Petrofund can actually help, since the fund covers release response, not routine removal.

Minnesota pricing follows the same shape as most Upper Midwest states: the tank itself is cheap, the ground around it is expensive. Here is what each piece typically runs in 2026.
| Line item | Typical range | What it covers |
|---|---|---|
| Above-ground / basement tank removal | $600 – $1,500 | Drain, cut, haul, dispose. Typically a one-day job. |
| Underground tank removal (no contamination) | $1,800 – $3,500 | Excavation, disposal, soil sampling, backfill. |
| Tank sweep (locate a suspected buried tank) | $275 – $425 | GPR or magnetometer scan of the property. |
| Local permit / closure registration | $100 – $250 | Varies by city and county in Minnesota. |
| Soil remediation (if contamination found) | $12,000 – $45,000+ | Scales with volume, depth, and groundwater impact. |
What the Petrofund actually pays for (and why removal usually isn’t on the list)
Minnesota’s Petroleum Tank Release Compensation Fund is one of the more generous state cleanup funds in the country — up to 90% of reasonable and necessary corrective-action costs, capped at $2 million per release. That headline number leads a lot of Minnesota homeowners to assume the fund will cover pulling their tank out of the ground. It won’t.
The Petrofund is a response fund, not a removal subsidy: it reimburses costs tied to investigating and cleaning up a confirmed petroleum release, not the routine mechanical work of excavating and disposing of an intact tank. Where it does connect to a removal project is at the margins — soil samples pulled during the dig, and excavation of contaminated soil once the MPCA has signed off on it as necessary corrective action. If your tank comes out clean, which is the outcome every homeowner wants, there is no release to file a claim against in the first place.
Eligibility also depends on paperwork discipline: the tank owner needs to be current on state fund fees, the release has to be reported properly, and the closure has to be performed by a registered contractor. Ask any Minnesota contractor you’re considering how they document a release for Petrofund purposes — an undocumented dig can leave you covering cleanup costs the fund would otherwise have picked up.

Minnesota’s older neighborhoods — much of Minneapolis and St. Paul, and the first-ring suburbs built before natural gas service reached them — were originally heated with oil delivered to a 275- or 550-gallon buried steel tank. When a home converted to gas or electric heat, the tank was often simply abandoned in place rather than removed, capped and left underground where it has continued corroding for decades.
This is why so many Minnesota sellers discover a tank they never knew existed, usually during a pre-listing inspection or a buyer’s tank sweep. A GPR sweep costs a small fraction of what an undiscovered leaking tank can cost after closing, which is why more Minnesota real estate attorneys are recommending one as routine due diligence on pre-1970s homes rather than something to skip. See our GPR tank sweep guide for how the scan itself works.
Choosing a Minnesota-registered closure contractor
- →Confirm MPCA registration. Only a registered closure contractor can perform tank removal work that preserves your Petrofund eligibility if a release turns up.
- →Ask about local permitting. Minneapolis, St. Paul, and the surrounding counties each run their own permit process — a contractor who works your specific city regularly will know it cold.
- →Get the Petrofund conversation in writing. If contamination is found, ask exactly how your contractor documents it for a Petrofund claim before they start digging, not after.

Frequently Asked Questions
How much does oil tank removal cost in Minnesota?
A clean underground oil tank removal in Minnesota typically runs $1,800–$3,500, with above-ground and basement tanks running less, around $600–$1,500. A tank sweep to locate a suspected buried tank costs $275–$425. If soil sampling turns up contamination, remediation is a separate, much larger cost — often $12,000–$45,000 depending on how far it has spread.
Does the Petrofund pay for removing an oil tank in Minnesota?
No — this is the single most common misunderstanding Minnesota homeowners have. The Petroleum Tank Release Compensation Fund (Petrofund) reimburses up to 90% of reasonable and necessary corrective-action costs after a confirmed release, up to $2 million per incident. But the routine cost of pulling a tank out of the ground is not an eligible expense. What can be reimbursed is the work tied to responding to a leak: soil sampling taken during the removal, and excavation of contaminated soil once the MPCA has approved it as necessary corrective action. If your tank comes out clean, there is nothing to file a Petrofund claim for — which is actually the outcome you want.
Who regulates oil tank removal in Minnesota?
The Minnesota Pollution Control Agency (MPCA) oversees petroleum tank releases and cleanup standards statewide. A registered tank closure contractor must perform the work, and the release (if any) has to be properly reported to MPCA to preserve Petrofund eligibility later.
Do I need a permit to remove an oil tank in Minnesota?
Most Minnesota municipalities require a local permit for underground tank closure work, and your contractor should register the closure with MPCA. Requirements and fees vary by city and county — Minneapolis, St. Paul, and the surrounding suburbs each have their own permitting office, so ask your contractor to confirm the specific local process before work starts.
Why do so many Minneapolis and St. Paul homes still have buried oil tanks?
Minnesota’s older housing stock — particularly homes built before natural gas service expanded through the Twin Cities in the mid-20th century — was commonly built with a buried 275- or 550-gallon steel heating oil tank. Many of these were abandoned in place, not removed, when owners switched to gas or electric heat, which is why sellers routinely discover a tank they never knew existed during a pre-listing inspection or a buyer’s tank sweep.
Is a tank sweep required before buying a home in Minnesota?
It is not a statewide legal requirement, but it is increasingly standard practice, especially for pre-1970s homes in Minneapolis, St. Paul, and older first-ring suburbs. A GPR tank sweep costs a fraction of what an undiscovered leaking tank could cost after closing, and many Minnesota real estate attorneys now recommend one as routine due diligence.
