Before natural gas became available in 1957, many homes were heated by furnace oil. The tank feeding the furnace was stored underground and held between 300 and 1,000 gallons of oil. Once houses were converted to natural gas, the tanks were often left buried beneath the soil and not all were emptied properly. The containers rust and can allow oil to leach into the soil. The oil can then find its way into an older home’s perimeter drainage system and flow into the storm sump, resulting in a fuel oil odor inside the home. The oil can also run into a neighbour’s drainage system and cause the same problem. In the past, leaving the abandoned tanks in the ground and filling them with sand was standard practice.
But that’s not the ideal option because the sand doesn’t always fill all the voids in a tank. Some insurance companies won’t provide insurance unless a problem tank is addressed. The British Columbia Fire Code governs the removal or abandonment of an underground oil storage tank. If an owner removes an underground oil storage tank, or abandons its place, or temporarily takes it out of service, the British Columbia Fire Code requires the owner to use good engineering practices. In addition, a local government, such as a municipality, may also regulate the removal or abandonment of an underground oil storage tank. If the contents of an underground oil storage tank spread to the surrounding area in a quantity or concentration that exceeds the limits in the provincial Contaminated Sites Regulation, the site is considered contaminated.
If the site is contaminated, the Environmental Management Act and the Contaminated Sites Regulation require the owner to remediate the property. The legislation also establishes who must pay for the remediation, including, in some cases, a former owner. According to the Real Estate Council of British Columbia, listing agents have a duty to familiarize themselves with the property that they have listed and, where they suspect an unused or abandoned underground storage tank may be present, to take necessary steps to determine if one exists. If a seller is aware of an unused or abandoned underground storage tank, that seller has an obligation to disclose this fact. An unused or abandoned underground storage tank is considered to be a material latent defect and, therefore, its presence must be disclosed in writing on the Property Disclosure Statement, as required by section 5-13 of the Council Rules.
FAQ: How do I know if there is an abandoned oil tank buried on the property? The age of your home is the first thing to consider.
