§ 35-11-1429 — Tank requirements; rulemaking authority

(a) Cathodic protection shall be installed and operated on
all internally lined underground storage tanks no later than
June 30, 2008.
(b) All underground storage tank systems that dispense
more than five hundred thousand (500,000) gallons per month of a
regulated substance shall be replaced with double wall tanks and
lines with interstitial leak monitoring no later than June 30,
2012, or thirty (30) years from the date of installation of the
underground storage tank, whichever is later.
(c) Double wall underground storage tanks and lines with
interstitial leak monitoring shall be installed whenever any
underground storage tank is installed.
(d) Double wall underground storage tank system lines with
interstitial leak monitoring shall be installed whenever any
line is installed on any underground storage tank system. Except
piping connected to field-constructed underground storage tank
systems with a capacity exceeding fifty thousand (50,000)
gallons or piping that is used for an airport hydrant system, if
existing single wall underground piping connected to an
underground storage tank system fails due to corrosion or fails
and has been recalled by the manufacturer, the entire run of
single wall piping shall be replaced with double wall piping
with interstitial monitoring regardless of the length of piping
requiring repair.
(e) The council may promulgate rules and regulations to
administer this section after recommendation from the director.
(f) A double wall and interstitially monitored underground
storage tank or underground piping installed after December 1,
2005, shall be interstitially monitored for the lifetime of the
tank or piping.
(g) Except essential homeland security systems, emergency
generator systems and systems used for other disaster relief
efforts, if a new piping interstitial monitoring system is
installed and sump sensors are used as standalone automatic leak
detectors, the system shall be configured to shut off the flow
of product in that piping run when a sump sensor triggers an
alarm.
