A. Owners and
operators of UST systems with spill and overfill prevention equipment and
containment sumps used for interstitial monitoring of piping shall meet the
following requirements to ensure the equipment is operating properly and it
will prevent releases to the environment.
1.
Spill prevention equipment (e.g., a catch basin, spill bucket, or other spill
containment device) shall prevent releases to the environment by meeting one of
the following requirements.
a. The equipment
is double walled and the integrity of both walls is periodically monitored at a
frequency no less than the frequency of the walkthrough inspections described
in LAC 33:XI.513. Owners and operators shall begin meeting Subparagraph b of
this Paragraph and conduct a test within 30 days of discontinuing periodic
monitoring of the equipment.
b. The
spill prevention equipment is tested at least once every three years to ensure
the equipment is liquid tight by using vacuum, pressure, or liquid testing in
accordance with one of the following criteria:
i. requirements developed by the manufacturer
(owners and operators may use this option only if the manufacturer has
developed requirements);
ii. in
accordance with LAC 33:XI.501.A; or
iii. requirements developed by the department
to be no less protective of human health and the environment than the
requirements listed in Clauses i and ii of this

equipment is double walled and the integrity of both walls is periodically
monitored at a frequency not less than the frequency of the walkthrough
inspections described in LAC 33:XI.513. Owners and operators shall begin
meeting Subparagraph b of this Paragraph and conduct a test within 30 days of
discontinuing periodic monitoring of the equipment.

monitoring of piping is tested at least once every three years to ensure the
equipment is liquidtight by using vacuum, pressure, or liquid testing in
accordance with one of the criteria in Clauses 1.b.iiii of this
Subsection.
3. Overfill
prevention equipment shall be inspected at least once every three years. At a
minimum, the inspection shall ensure that the overfill prevention is set to
activate at the correct level specified in LAC 33:XI.303.D.3.a.ii and will
activate when regulated substance reached that level. Inspections shall be
conducted in accordance with one of the criteria in Paragraph A.1.b.i.iii. of
this Section.
B. Owners
and operators shall begin meeting the following requirements.
1. For UST systems in use on or before
September 20, 2018 the initial spill prevention equipment test, containment
sump test, and overfill prevention equipment inspection shall be conducted no
later than September 20, 2021.
2.
For UST systems brought into use after September 20, 2018, these requirements
apply at installation.
C.
Owners and operators shall maintain records for spill prevention equipment,
containment sumps used for interstitial monitoring of piping, and overfill
prevention equipment in accordance with LAC 33:XI.509.B as follows:
1. all records of testing or inspection shall
be maintained for three years; and/or
2. for spill prevention equipment and
containment sumps used for interstitial monitoring of piping not tested every
three years, documentation showing that the prevention equipment is double
walled and the integrity of both walls is periodically monitored shall be
maintained for as long as the equipment is periodically monitored.
D. Owners and operators shall
comply with the following requirements whenever a test of spill prevention
equipment or containment sumps used for interstitial monitoring of piping or an
inspection of overfill prevention equipment fails.
1. Failed equipment shall be repaired or
replaced within 30 days of failing the test or inspection unless an alternative
timeframe is granted, in writing, by the department.
2. Repairs to failed equipment shall be
conducted in accordance with LAC 33:XI.507.
