Tribal Underground Storage Tank Compliance Pilot

In January 2022, EPA’s Office of Enforcement and Compliance Assurance (OECA) launched a three-year Pilot to improve compliance at tribal underground storage tank (UST) facilities. The Pilot aims to achieve this goal through two key mechanisms: (1) ensuring tribal governments are provided with information on, and notice of, consultation opportunities related to announced inspections, compliance assistance, noncompliance, and possible enforcement responses; and (2) utilizing expedited enforcement tools when appropriate. These expedited tools result in a faster return to compliance and lower penalty that traditional enforcement.
