Oil Tank Removal Cost in Maryland (2026)
A standard underground oil tank removal in Maryland costs $1,800-$3,800 and is overseen by the MDE Oil Control Program, which requires notification, a licensed contractor, certified soil sampling, and a closure report. Maryland does not run a general reimbursement fund for routine removal, so budget for the job itself rather than counting on state assistance.
Quick Answer
Underground tank removal in Maryland runs $1,800-$3,800 for a standard 275-550 gallon tank; above-ground and basement tanks run $500-$1,200. MDE requires advance notification, certified soil sampling, and a closure report. Maryland's state cleanup fund is narrow and release-driven — it is not a rebate for a tank that comes out clean.

| Job Type | Typical Cost |
|---|---|
| Above-ground / basement tank removal | $500 – $1,200 |
| Underground tank removal (275-550 gal, clean closure) | $1,800 – $3,800 |
| Underground tank removal (1,000+ gal) | $3,000 – $5,000 |
| GPR tank sweep (confirm tank location) | $275 – $450 |
| Soil sampling / lab analysis | $300 – $700 |
| Minor soil remediation | $12,000 – $25,000 |
| Major soil remediation (groundwater involved) | $25,000 – $50,000+ |
| MDE notification / local permit | $100 – $300 |
These figures hold across most of the state. Baltimore's dense, older rowhouse neighborhoods tend to run toward the top of the range because of narrow lots and limited rear access, while suburban Montgomery and Prince George's counties generally track closer to the middle. Properties anywhere near the Chesapeake Bay watershed — tidal creeks, wetlands, or the bay itself — can see higher remediation costs if contamination is found, since MDE applies tighter cleanup standards in those areas.
What the MDE Oil Control Program requires
The Maryland Department of the Environment (MDE) Oil Control Program is the primary regulatory authority for underground storage tank closure in the state. Before work begins, your contractor files advance notification with MDE. During the job, soil samples are collected from the excavation and analyzed by a certified lab. After removal, the contractor files a closure report — the document buyers, lenders, and title companies will ask for at resale.
Because most of Maryland's land area drains into the Chesapeake Bay, MDE pays particularly close attention to tank work near waterways, tidal wetlands, and designated critical areas. If your property sits close to water, expect your contractor to flag this early — it can mean additional soil sampling locations or a more conservative closure standard than a property farther inland would face.
Why the state cleanup fund rarely helps
The confusion around Maryland oil tank reimbursement usually comes from mixing up two different things. The MDE Oil Control Program is the regulatory side — it sets the rules for how a tank has to be closed, not a source of money for homeowners. The Oil Contaminated Site Environmental Cleanup Fund is the financial side, but it is narrower than most people assume: it is built to respond to specific petroleum releases that meet its eligibility criteria and is subject to state appropriation, not a standing rebate for routine tank removal on a tank that never leaked.
If you are hoping to offset removal costs, the more realistic paths are a standalone pollution liability policy purchased before any problem occurred, or a claim against a fuel delivery company if a documented delivery error caused a release. Budget for the removal itself as an out-of-pocket cost, and treat any fund eligibility as something to investigate only after contamination is confirmed.

Frequently Asked Questions
How much does oil tank removal cost in Maryland in 2026?
A standard underground tank removal in Maryland runs $1,800-$3,800 for a 275-550 gallon tank with clean soil, and $3,000-$5,000 for larger 1,000+ gallon tanks. Above-ground and basement tank removal is cheaper since there is no excavation, typically $500-$1,200. A GPR tank sweep to confirm a tank exists before scheduling removal costs $275-$450. If soil sampling turns up contamination, remediation runs $12,000-$25,000 for a contained release and $25,000-$50,000 or more if it has reached groundwater — more likely in Chesapeake Bay watershed areas where MDE applies stricter standards.
Is there a Maryland reimbursement fund for oil tank removal?
Not for routine removal. Maryland's Oil Contaminated Site Environmental Cleanup Fund is narrow, release-driven, and subject to state appropriation — it responds to specific contamination events that meet its eligibility criteria, not a standing rebate for pulling a sound tank out of the ground. Homeowners expecting the fund to offset a normal removal are usually disappointed. Where Maryland homeowners actually recover money is more often a standalone pollution liability policy purchased in advance, or a claim against a fuel delivery company if a documented delivery error caused a release.
What does the MDE Oil Control Program require for tank removal?
The Maryland Department of the Environment (MDE) Oil Control Program oversees underground storage tank closure statewide. That means advance notification before work starts, a licensed contractor performing the removal, certified soil sampling from the excavation, and a closure report filed once the job is done. Because most of Maryland drains into the Chesapeake Bay watershed, MDE applies particularly strict cleanup standards near waterways, wetlands, and tidal areas — worth knowing if your property is anywhere near water.
Does oil tank removal cost more in Baltimore than the rest of Maryland?
Often, and it comes down to housing stock and access more than a different regulatory process. Baltimore's rowhouse neighborhoods — many built before 1950 — have narrow lots and limited rear-yard access that can slow excavation and add cost, a pattern similar to older cities elsewhere in the Northeast. Annapolis and the DC suburbs of Montgomery and Prince George's counties tend to run close to the statewide range, though older Annapolis neighborhoods near the water face the same stricter MDE watershed scrutiny as other Chesapeake-adjacent properties.
Do I have to disclose an oil tank when selling a home in Maryland?
Yes. Maryland sellers must report known underground storage tanks on the property disclosure, and it's one of the most common issues that delays settlement in the Baltimore-Washington corridor when it surfaces late. Getting a tank swept or removed before listing — with documentation in hand — avoids a buyer's attorney holding up closing over an undocumented tank. If financing is also part of the picture, our guide to FHA and VA loan requirements covers how lenders in Maryland typically handle an unresolved tank.
