Portland Oil Tank Decommissioning
Helping Customers in Vancouver, Beaverton, Tigard, and the Greater Portland Area Uninstall Their Underground Oil Tanks
An inactive or deteriorating underground oil tank on your property can pose serious environmental risks and even potential legal issues. Traditionally, these tanks are used to store heating oil for homes and buildings. Over time, however, they can become corroded, leading to the risk of oil leaks that can contaminate the surrounding soil and groundwater. At Environmental Works, we are committed to providing expert oil tank decommissioning services to help you mitigate these risks and ensure your property is safe and compliant.
Your oil tank may need to be decommissioned if:
- You suspect a leak: If you detect the smell of heating oil near the tank site or notice unexplained oil consumption spikes, it could indicate that your tank is leaking.
- It’s corroded: Visible signs of corrosion on the tank or piping can signal a deteriorating tank.
- There’s excess water in the tank: If you regularly find water in your tank, it can be a sign of a compromised tank structure.
- It’s old: Most oil tanks were not designed to last more than a few decades. If your tank is old, it could be time for decommissioning.
- Your insurance requires it: Some insurance companies require the decommissioning of out-of-use or aging tanks.
Being proactive in decommissioning your oil tank can help prevent potential damage to your property and the environment. Trust Environmental Works to handle the process with utmost care and professionalism.
Environmental Works is here to help customers throughout the Greater Portland Area and beyond safely decommission and dispose of old or damaged underground oil tanks. Call us at (503) 719-6715 to request a free estimate!
