The owners/operators of most underground storage tanks in Massachusetts were required to have their USTs and associated piping inspected by Third-Party Inspectors by August 8, 2010. 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. See Delay of New UST Forms Rollout - April 2015 and Guidance on Submitting UST Forms Electronically for additional information.
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.

Until the new MassDEP online underground storage tank (UST) data management system is available, UST owner/operators and third-party inspectors should continue using the existing FP-290, FP-290R and FP-289 forms to meet their registration, status change and inspection submittal requirements.
