A. LAC
33:XI.599.Appendix A lists codes of practice developed by nationally-recognized
associations or independent testing laboratories that shall be used to comply
with these regulations.
B. New UST
Systems Near Active or Abandoned Water Wells. In order to prevent releases due
to structural failure, corrosion, or spills and overfills for as long as the
UST system is used to store regulated substances, all UST systems installed
between December 22, 1988, and December 20, 2008, within 50 feet of an active
or abandoned water well shall meet the requirements of LAC
33:XI.703.C.
C. Standards for UST
Systems Installed after December 20, 2008. In order to prevent releases due to
structural failure, corrosion, or spills and overfills for as long as the UST
system is used to store regulated substances, all UST systems installed after
December 20, 2008, shall have secondary containment in accordance with
Subsection D of this Section and use interstitial monitoring for tanks and
piping in accordance with LAC 33:XI.701.A.6 and 701.B.4.
1. If a single-walled UST is placed in the
ground at the location where it is to be put into service prior to December 20,
2008, the UST owner is allowed 90 days (until March 20, 2009) to complete the
UST system installation without having to comply with the secondary containment
requirements in Subsection D of this Section.
2. The department may grant an extension to
these dates only in the event that the UST or UST system installation is
delayed due to adverse weather conditions or other unforeseen, unavoidable
circumstances. A written contract alone does not qualify as an unforeseen,
unavoidable circumstance. In order to obtain an extension, the UST owner shall
submit a written request to the Office of Environmental Assessment, describing
the circumstances that have caused the installation delay.

replacement dispenser at an existing facility where new piping is added to the
UST system to connect the new dispenser to the existing system;
iii. in any installation of a replacement
dispenser at an existing facility where the piping that connects the dispenser
to the existing piping is replaced, including replacing the metal flexible
connector, riser, or other transitional components that are beneath the
dispenser and the impact shear valve and that connect the dispenser to the
piping. Replacing an existing dispenser where no piping and none of the piping
that connects the dispenser to the existing piping are replaced does not
require the addition of an under-dispenser containment sump;
and
b. shall be
liquid-tight on its sides, bottom, and at any penetrations, and be maintained
free of storm water and debris. Regulated substances spilled into any
under-dispenser containment sump shall be immediately removed upon discovery to
the maximum extent practicable.
5. Submersible Turbine Pump (STP) Secondary
Containment. After December 20, 2008, secondary containment for submersible
pumps:
a. is required under the following
conditions:
i. in any installation of a new
STP at a new facility;

installation of an STP (the entire STP, STP housing, and riser pipe) at an
existing facility where new piping is added to the UST system to connect the
new STP to the existing system;
iii. in any installation of a replacement STP
(the entire STP, STP housing, and riser pipe) at an existing facility where the
piping that connects the STP to the existing piping is replaced. Replacing the
metal flexible connector with a single-walled flexible connector requires the
addition of a containment sump. Replacing the metal flexible connector with a
double-walled flexible connector does not require the addition of a containment
sump as long as the newly-installed STP is secondarily contained, and replacing
an existing STP where no piping is replaced does not require the addition of
STP secondary containment; and
b. can consist of either a built-in secondary
containment system or a STP containment sump. STP containment installed after
December 20, 2008, shall be liquid-tight on its sides, bottom, and at any
penetrations, and be maintained free of storm water and debris. Regulated
substances spilled into any STP containment sump shall be immediately removed
upon discovery to the maximum extent practicable.
