It is unlawful to fill or dispense product from UST systems lacking an operating permit. In order to receive and maintain an operating permit, owners or operators of underground storage tank systems must obtain a compliance inspection of each tank system and a subsequent inspection every three years. Issuance of an operating permit is based on a compliance inspection that indicates that the UST is in compliance with Montana's operation and maintenance requirements.
Compliance inspections will be conducted by private-sector inspectors licensed by DEQ. State and local UST program staff may conduct inspections as part of their oversight duties, or may conduct inspections to follow-up on complaints.
NOTE: Routine line- and tank-tightness tests and corrosion-prevention system tests are also needed. Find out more .
