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). Hired directly by tank owner/operators, these professionals document the results of their on-site inspections, review facility record keeping to ensure it meets UST Program requirements, and report their inspection findings to the Department of Environmental Protection (MassDEP) via the nSPECT Online Filing System
. While TPIs provide compliance advice to their clients, they are not authorized to enforce laws or regulations.
