Why Remove Old Tanks?

The primary danger is corrosion. Underground tanks are made of bare steel, which inevitably rusts over time. Once the tank walls thin or develop holes, heating oil leaks into the surrounding soil. This contamination is a serious issue that can ruin your property value, threaten local groundwater, and potentially spread to neighboring lots. Because of these risks, most banks won’t mortgage homes with active underground tanks, and insurance companies often refuse coverage. Removing the tank isn’t just about safety; it’s about ensuring your home remains sellable and insurable.

The Removal Process

The extraction process is highly regulated and must be handled by licensed professionals to ensure it meets provincial environmental standards.

1. Permitting & Planning: Before any dirt is moved, your contractor must obtain the necessary municipal and fire department permits.
2. Emptying & Cleaning: The tank’s contents are pumped out, and any residual sludge is safely removed and transported to a certified disposal facility.
3. Excavation: Using heavy machinery, professionals carefully uncover the tank and its associated piping.
4. Inspection & Soil Testing: This is the most critical phase. Once the tank is removed, the surrounding soil must be visually inspected and tested by a qualified environmental professional. Samples are sent to a laboratory to check for petroleum hydrocarbons.
5. Remediation (If Needed): If the soil tests indicate contamination, remediation steps must be taken. This involves excavating the affected soil and replacing it with clean fill to meet BC government standards.
6. Site Restoration: Once the site is confirmed clean, the excavation is backfilled and restored to grade.

Safety Requirements

Safety is the top priority during every step. The work area must be properly cordoned off, and the tank itself must be transported in compliance with hazardous waste regulations. By hiring a qualified expert, you ensure that all safety protocols are followed, protecting both your home’s foundation and the local environment.

Soil Testing & Site Restoration

Don’t be tempted to skip the testing. Documentation is your best friend when selling your home. You need a final “clean soil” report to prove to future buyers and mortgage lenders that the site has been successfully remediated. Keep this report, along with your disposal manifests, in a safe place with your property records.
