However, be aware that there may have been multiple small oil spills around the fill pipe when fuel was delivered. Or, the tank could have had problems in the past that you’re not aware of. Keep in mind that you’re responsible for cleaning up any contamination from a leak. DEQ recommends you check your tank for leaks before listing your home. You may want to consider having a licensed service provider test the soil underneath to determine whether or not it has leaked. This service may cost about $200 to $300.

"Decommissioning" is a generic term for taking a tank out of service by cleaning it, then removing it or filling it in place with an inert material. If you – or the buyer – would like to have the decommissioning performed in compliance with state standards, you must:
*For example, you may choose not to clean the tank and remove it or fill the tank with an inert material or to have soil samples collected. However, be aware that some buyers or lenders may want the tank decommissioned to state standards so they do not assume liability for any problem found in the future.
Contractors or homeowners decommissioning their own tank must submit a report, and "certify" that their work is in compliance with all regulatory requirements and cleanup standards have been met.
The report and certification letter, as well as a fee for a clean decommission ($100), a Soil Matrix cleanup ($250), a Generic Remedy cleanup ($350) or a Risk-Based cleanup ($450), is submitted to DEQ.
If the required documentation and fees have been submitted, the DEQ then registers the certified cleanup report and sends a letter to the responsible person. The DEQ audits various certifications and contractors to ensure that the work meets acceptable standards.
It has come to DEQ's attention that contractors are being asked to recertify sites that have previously been issued a No Further Action letter by DEQ prior to 2/17/2000 or been certified as meeting standards by a contractor after 2/17/2000. The issue becomes what reliance, if any, can contractors and/or homeowners place on those earlier decommissioning or cleanup determinations. The advice DEQ has been giving is that the earlier determinations remain valid if:
If the contractors or homeowners have any questions about the new information, they should contact the HOT technical staff for assistance or send an email.
On a related matter, DEQ is occasionally asked how long the results from a site assessment are valid where an active tank remains in the ground. Because new spills or releases from an active tank can occur at any time, DEQ advises that site assessment samples should be relied on for no more than 90 days. After 90 days it is advisable for new assessment data to be collected. DEQ will not accept site assessment data that is more than 90 days old if used to certify a decommissioning or cleanup.
