Owner/operators of underground storage tank (UST) systems in Massachusetts are required to:
The owners/operators of most underground storage tank (UST) systems in Massachusetts are required to have those systems and their components inspected every three years by Third-Party Inspectors (TPIs).
MassDEP's TPI Certification Program ensures that those responsible for inspecting UST systems have the necessary knowledge and understanding of how these systems work. Qualified individuals are certified for five years and need to apply for renewal at least 90 days before their current certifications expire.
Hired directly by tank owner/operators, these professionals document the results of their on-site inspections, review facility record keeping to ensure it meets state requirements, and report their inspection findings to the MassDEP via nSPECT, an online reporting system.
Although TPIs provide compliance advice to their clients, they are not authorized to enforce laws or regulations.
