How Long Does Underground Oil Tank Removal Take?

June 1, 2026

Finding an underground oil tank on your Roselle Park, NJ property can quickly turn into a major concern, especially when you are buying or selling a home. One of the first questions homeowners ask is how long the removal process will take. Underground oil tank removal timelines often depend on permit approvals, tank accessibility, and whether contamination is found during excavation. Tanks buried under porches, driveways, or additions can also add time to the project because of the extra care and planning required for safe removal.

We recently spoke with a homeowner purchasing an older property who was concerned about a possible underground oil tank located beneath a front porch. Their biggest concern was understanding how permits, inspections, and limited access could affect the overall timeline before closing on the home.

What Is the Typical Timeline for Underground Oil Tank Removal?

In many cases, the actual physical removal of an underground oil tank only takes one to two days. However, the full process usually takes longer because of inspections, permits, scheduling, and possible environmental testing.

A typical underground oil tank removal project may include:

Tank location confirmation
Site inspection
Permit application and approval
Tank excavation and removal
Soil inspection and testing
Cleanup or remediation if contamination is found
Final documentation and permit closure

For many homeowners, the entire process can take anywhere from two to six weeks depending on local permitting offices and site conditions.

Why Do Permits Affect Oil Tank Removal Timelines?

Most towns and municipalities require permits before underground oil tanks can be removed. Permit timelines vary significantly depending on the local building department and environmental regulations.

Some municipalities issue permits within a few days, while others may take several weeks. In many areas, towns are legally allowed a set review period before issuing permits. Permit requirements often include:

Site plans
Tank details
Contractor licensing information
Environmental documentation
Inspection scheduling

The U.S. Environmental Protection Agency recommends properly closing or removing unused underground storage tanks to help prevent leaks and soil contamination.

Can Underground Oil Tank Removal Be Completed in One Day?

Yes, some underground oil tank removals can be completed in a single day if:

The tank is easy to access
No structures block excavation
The tank is relatively small
Soil contamination is not present
Permits have already been approved

However, more complicated removals may require additional time.

What Makes Underground Oil Tank Removal Take Longer?

One of the biggest factors affecting removal time is accessibility. Tanks located beneath porches, decks, driveways, garages, or home additions are more complicated to remove safely.

These situations often require:

Specialized excavation methods
Structural protection
Partial demolition or removal of obstacles
Smaller equipment or hand digging
Additional safety precautions

When a tank is located under a structure, we usually perform a detailed site inspection first to determine the safest removal strategy.

Does Soil Contamination Increase the Timeline?

Yes. If the tank has leaked oil into the surrounding soil, the project timeline can increase substantially.

Signs of contamination may include:

Oil odors around the property
Stained soil
Failed soil tests
Corroded or damaged tanks

If contamination is found, environmental remediation may be required. This can involve soil removal, testing, and reporting to local environmental agencies.

The New Jersey Department of Environmental Protection notes that leaking underground storage tanks can pose environmental and financial risks if not addressed properly.

Does Tank Size Affect Removal Time?

Yes. Larger underground oil tanks generally require more excavation and disposal work. Residential tanks are commonly between 275 and 1,000 gallons, but older properties may contain larger systems.

Tank size can affect:

Excavation scope
Equipment requirements
Disposal procedures
Soil testing areas
Permit documentation

Is removing an oil tank under a porch more expensive?
