Maryland MDE Oil Tank Regulations
Maryland regulates petroleum underground storage tanks under COMAR 26.10 (Code of Maryland Regulations). The MDE Oil Control Program oversees tank registration, closure notifications, and spill response. Key requirements for homeowners:
- Tank registration: Residential USTs over 2,000 gallons are subject to MDE registration requirements. Smaller home heating tanks often fall under less stringent rules but still require proper closure.
- Licensed contractors required: Only MDE-licensed contractors may perform UST closure work in Maryland.
- Advance notification: Contractors must notify MDE before closure work begins.
- Soil and groundwater sampling: Required at the time of tank closure to determine if contamination is present.
- Clean closure documentation: If soil results meet MDE standards, a "no further requirements" determination is issued — valuable for real estate and insurance.
- Contamination response: If sampling detects petroleum above applicable standards, a corrective action plan must be submitted to MDE.
Oil Tank Removal Costs in Maryland
| Job Type | Typical Cost in MD |
|---|---|
| Above-ground / basement tank removal | $800 – $2,000 |
| Underground tank removal (clean) | $2,000 – $6,000 |
| Soil sampling / lab analysis | $400 – $800 |

Baltimore County and Montgomery County tend toward the higher end. Western Maryland and the Eastern Shore are typically less expensive due to lower labor rates.
Maryland Reimbursement Programs
Maryland operates the Underground Storage Tank Fund (USTF) which provides financial assistance to eligible tank owners for confirmed petroleum releases from registered USTs. If your tank has leaked and contamination is confirmed, you may qualify for reimbursement of a portion of corrective action costs after a deductible.
Eligibility depends on tank registration status, compliance history, and the nature of the release. Contact MDE's Oil Control Program at mde.maryland.gov or ask your contractor about current program availability and application procedures.
Real Estate Implications in Maryland
Maryland real estate agents report that buried oil tanks are among the most common issues that delay or kill home sales in older suburban communities — particularly in Baltimore metro, Annapolis, and the DC suburbs of Montgomery and Prince George's Counties. Most FHA, VA, and conventional lenders require either proof of clean tank closure or full removal before issuing a mortgage on properties with known tanks.
