Homeowner Oil Spill Cleanup Guide

Prevent Heating Oil Leaks and Spills

Cleaning up oil leaks from home heating systems can be very expensive. The average cost can range between $20,000 and $50,000, with some cleanups costing significantly more. Here are some ways to save money, help prevent leaks and spills, and protect the environment.

For all heating oil systems:

• Retain all oil delivery receipts. Keep them handy so you can track your oil demand. Unexpected increases may indicate a leak.
• At least every 10 years, have the oil tank cleaned out. Over time, water (from condensation) and sludge can cause corrosion resulting in leaks.

For underground tanks:

• Determine if the underground storage tank is made of steel (common) or fiberglass (rare). Most steel underground storage tanks will last approximately 10 to 20 years. If the tank is older than that or the age is unknown, replace it with an above ground storage tank. Locate your new tank under a shelter, or inside a basement or garage to prevent rust, corrosion, or damage.

For outdoor above ground tanks:

• Ask an oil technician to inspect the stability of the above ground tank. A full 275-gallon tank weighs more than 2,000 pounds! They have metal legs and should sit on a concrete pad. If the legs become loose or the pad cracks, the tank can fall over and rupture.
• Replace an outdoor above ground storage tank that has been uncovered for 10 years or longer. These tanks rust from the inside out, so cleaning or painting the outside does not usually prolong their life.
• Protect the tank from the weather, such as falling snow and ice, and prevent ruptures by tree limbs.
