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.
