Underground Storage Tank Facility Plan

Provides the definition of an Underground Storage Tank facility plan, outlines who is required to submit a plan to TCEQ, lists the required forms, and provides fee information.

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 is proposed in the Edwards Aquifer recharge or transition zone.

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)

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.

The fee is $650 per tank or piping system. For additional information on fees, view the Application Fee Form TCEQ-0574 ( PDF, Word), which includes a complete fee schedule.
