Underground Storage Tank Facility Plan
What is an Underground Storage Tank (UST) facility plan?
A UST facility plan is a detailed plan that outlines best management practices that will be implemented in order to protect water quality when a regulated underground storage tank facility is constructed in the Edwards Aquifer recharge or transition zones.
Who is required to prepare and submit a UST facility plan?
A UST facility plan is required for the construction or rehabilitation of a storage tank system or systems containing hydrocarbon or hazardous substance where the system(s) are located on the recharge zone or transition zone. A UST system includes tanks, piping, and related systems (30 TAC 213.5(a)(3)) .
When should a UST facility plan be submitted to the TCEQ?
A UST facility plan must go through the application submission and review process and be approved prior to the commencement of installation of the tank system.
