Aboveground Tank Removal Service
When your aboveground storage tank (AST) has outlived its safe and useful performance life, CommTank’s storage tank removal service is a quick, safe, and reliable way to decommission it.
For more than two decades, our team has provided clients throughout New England with successful removal and replacement of their aboveground storage tanks ranging from 500 to 30,000 gallons.
When to replace an aboveground storage tank
Indicators that a steel tank needs replacement include corrosion on the tank’s bottom, seams, welds, and piping. For any aboveground storage tank that is out of compliance, improperly abandoned, or suspected of leakage, CommTank has the expertise and experience to remove it quickly and efficiently, with minimal impact to your property and your business.
Are “empty” tanks hazardous?
Aboveground storage tanks deemed empty can be hazardous, as outlined by the Occupational Safety and Health Administration (OSHA). Appendix C of OSHA’S 29 CFR 1910-146 cites these examples of incidents involving “empty” tanks:
- Welding in and near tanks can ignite flammable vapors.
- Tanks that do not contain enough oxygen (less than 19.5%) can cause asphyxiation.
- Just because a tank has been “emptied” of its contents does not mean it is free of hazards.
- A tank is never safe for entry until properly and thoroughly evaluated to ensure that there are no actual or potential atmospheric hazards that can affect the oxygen content, flammability, or toxicity.

Complexities involved in aboveground storage tank projects
At CommTank, we’ve earned our success in the commercial industry by understanding the complexities involved in aboveground storage tank projects. Key complexities include knowledge of products and their flash points, as well as proper equipment applications.
Product knowledge is critical for pumping success
Since the equipment used to pump one type of fuel does not work for another, it’s vital to know the type of product in the tank. For example, some fuels (such as ethanol and biodiesel) can degrade rubber, so the choice of fuel hose or pump seals is important. Number 4 and 6 heating oil each require warming to reduce viscosity before they can be pumped, so the proper equipment must be used to ensure success.
Proper handling of tank vapors is critical for safety
Proper handling of potentially flammable tank vapors ensures everyone’s safety, and it all begins with product knowledge. For example, fuel oil will not ignite unless subjected to very high temperatures, but gasoline is highly flammable in normal temperature ranges.
The flash point for each fuel is listed below:
|Fuel||Flash point||Auto ignition temperature|
|Ethanol (70%)||16.6 °C (61.9 °F)||363 °C (685 °F)|
|Gasoline (petrol)||−43 °C (−45 °F)||280 °C (536 °F)|
|Diesel (2-D)||>52 °C (126 °F)||256 °C (493 °F)|
|Jet fuel (A/A-1)||>38 °C (100 °F)||210 °C (410 °F)|
|Kerosene||>38–72 °C (100–162 °F)||220 °C (428 °F)|
|Vegetable oil (canola)||327 °C (621 °F)|
|Biodiesel||>130 °C (266 °F)|
The CommTank team uses dry ice and an explosion proof blower to displace flammable vapors, and prepare aboveground tanks for transport or entry into a scrap yard.
