Underground Storage Tank Facility Plan

Content for a Edwards Aquifer underground storage tank facility plan.

An underground storage tank (UST) facility plan is required for the installation or replacement of underground storage tanks or piping on either the recharge or the transition zone of the Edwards Aquifer. In particular, storage tank (aboveground or underground) facilities that will store 500 gallons or more of static hydrocarbons or hazardous substances are regulated.

Double-walled tanks and product delivery piping are required. Continuous leak detection is required that will alert the owner at all times, even when the facility is not occupied. Containment sumps beneath piping sumps are also required elements of the plan.

Required Application

The forms for a complete UST facility plan specify additional information that must be attached, such as maps, site plans, geologic assessment, a narrative description of the equipment that will be installed, and construction detail sheets.

The fee is $650 per tank or piping system.

A UST facility plan must be submitted for review and approved prior to installation.

A geologic assessment is not required for installation projects at existing facilities where the site is paved.
