An aboveground storage tank (AST) facility plan is required for the
installation of permanent aboveground storage tanks at a facility
that will have a total capacity of 500 gallons or more on either
the recharge or transition zones of the Edwards Aquifer. In
particular, ASTs that will store static hydrocarbons or hazardous
substances are regulated.
Required Application
The forms for a complete AST facility
plan specify additional information that must be attached, such
as maps, site plans, drawings for the containment area, and a
description of spill controls and response actions. The fee is $500
per tank.
A containment area is a required element of the plan.
Double-walled tanks are acceptable in place of the tank containment
requirement. If underground piping is proposed, then a continuous
leak-detection system is required for the piping.
A geologic assessment is not required for installation projects
at existing facilities where the site is paved.
An AST facility plan must be submitted for
review and approved prior to installation.
