We inspect the property, locate the tank, and perform testing to determine its condition and whether any leakage has occurred.
Residual product is pumped out and properly disposed of. The tank is then excavated, removed, and transported to a licensed disposal facility.
Soil samples are collected and sent to a certified lab. We prepare and file all required reports so the property receives an official clean closure.
Many homeowners have no idea there's a buried tank on their property until they're going through a real estate transaction and a title search or inspection turns one up. Common signs include an old fuel oil fill pipe or vent pipe sticking up near the foundation, an abandoned basement fuel line, or records in the town or county file showing a tank was once registered. If you have an older home — particularly one built before the 1980s — it's worth having a property assessment done. Allied All-City can help locate buried tanks and determine their status.
New York State does not require homeowners to proactively remove an oil tank simply because it exists. However, if a tank is leaking or has been abandoned without being properly decommissioned, you may be legally obligated to remediate any contamination. In practice, most lenders and title insurance companies will require tank removal or documented clean closure before approving a mortgage or issuing title on a property with a known buried tank. So while it may not always be a legal mandate, it's almost always a practical requirement for property transactions.
Decommissioning refers to taking a tank out of service without physically removing it from the ground. This typically involves pumping out residual product, cleaning the interior, filling the tank with an inert material like sand or concrete, and capping all openings. Full removal means the tank is physically excavated and taken off the property. In most cases on Long Island, lenders and regulators prefer or require full physical removal, especially for residential properties, because a decommissioned tank still sitting underground can cause issues in future transactions. Allied All-City can advise on which approach is appropriate given your situation.
The physical removal of a typical residential underground oil tank usually takes one day — sometimes less, depending on the size and accessibility of the tank. However, the full process, including soil sampling and laboratory analysis, takes longer. Lab results typically come back within one to two weeks. Once results are reviewed, final closure reports are prepared and submitted to the applicable regulatory agencies. The total timeline from initial assessment to receiving your closure documentation is generally two to four weeks, though this can vary depending on lab turnaround and whether any contamination is found that requires additional remediation.
If laboratory results show petroleum contamination in the soil around the tank, the scope of work expands to include remediation. Depending on the extent of the contamination, this may involve removing additional contaminated soil from the excavation, transporting it to a licensed disposal facility, and collecting additional soil samples to confirm cleanup is complete. In some cases, groundwater testing may also be required. Allied All-City coordinates all of this and keeps you informed at every step. Contamination doesn't have to be a crisis — it's a manageable problem when you have an experienced contractor and clear documentation throughout the process.
Yes. Allied All-City works with residential homeowners, commercial property owners, and industrial clients across Long Island. Commercial and industrial sites often have larger tanks, more complex regulatory requirements, and tighter documentation standards — all areas where our team has direct experience. We handle above-ground storage tanks at commercial facilities as well as underground tanks at multi-family properties, retail sites, and industrial yards. If you manage a portfolio of properties or need to address multiple tanks at once, we can scope and schedule that work efficiently. Contact us to discuss your specific situation and we'll put together the right approach.
