All of PASS’ UST operator training courses meet and exceed the federal requirements for UST operator training and are offered through our in-house designed and built Learning Management System (LMS). PASS’ state-specific training courses are custom tailored to meet state requirements, and are accepted by more states than any other training provider.  Our courses are available on demand, 24/7 and are accessible from any internet-connected computer, tablet, or phone. The student can complete an entire course in a single session or take the course in segments. The training may be stopped and restarted, allowing for maximum schedule flexibility. PASS also does not impose time restrictions on course access, so students may take as much time as they need to complete their training.  Once training is completed a certificate is available to save and print.

All regulated UST facilities in Missouri will be inspected by the Department of Natural Resources (DNR) at least once every three years.  Prior to an inspection, the facility will receive a notification letter.  If the facility is not insured through the Petroleum Storage Tank Insurance Fund, a Records Request will accompany the notification letter.  The Records Request requires the facility owner/operator to assemble the listed facility records and submit them to the Missouri Department of Natural Resources Tanks Compliance and Enforcement Unit within 30 days of the date of the letter.
