By August 8, 2010, the owners/operators of most underground storage tanks in Massachusetts are required to have their USTs and associated piping inspected by Third-Party Inspectors. Inspections must be repeated every three years.

Third-Party Inspectors conduct detailed inspections of USTs and piping systems, and:

• Document the results of their on-site inspections;
• Review facility record keeping to ensure it meets UST Program requirements; and
• Submit reports on their findings to the Department of Environmental Protection (MassDEP).

Reports must be submitted to MassDEP on the Third-Party Underground Storage Tank Inspection Report (FP-289) form. Third-Party Inspectors are hired directly by tank owners and operators. Inspectors report UST facts to MassDEP. While they provide advice to their clients about compliance issues, they are not authorized to enforce laws and regulations.
