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 $500 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.
