release prevention equipment.
PUBLISHER’S NOTE: The secretary of state
has determined that the publication of the
entire text of the material which is incorporated by reference as a portion of this rule would
be unduly cumbersome or expensive. This
material as incorporated by reference in this
rule shall be maintained by the agency at its
headquarters and shall be made available to
the public for inspection and copying at no
more than the actual cost of reproduction.
This note applies only to the reference material. The entire text of the rule is printed here.
(1) Alternatives Allowed. All underground
storage tank (UST) systems which are in-use
must comply with one (1) of the following
requirements:
(A) New UST system performance standards in 10 CSR 26-2.020; or
(B) The upgrading requirements in sections (3)–(5) of this rule.
(2) Any UST which was not permanently
closed by being removed or filled with an
inert, solid material before December 22,
1988, and that does not meet the requirements of section (1) shall be permanently
closed in accordance with the requirements in
10 CSR 26-2.060 through 10 CSR 26-2.064.
If the UST was taken out of operation by
August 28, 1989, but is still in the ground,
the person or party responsible for permanently closing the UST is/are the person(s)
who owned the UST immediately before the
discontinuation of its use.
(3) Tank Upgrading Requirements. Tanks must
be upgraded to meet one (1) of the following
requirements in accordance with a code of
practice developed by a nationally-recognized
association or independent testing laboratory:
(A) Interior Lining or Tank Retrofit. A
tank may be upgraded by internal lining or
retrofit if—
1. The lining is installed in accordance
with the requirements of 10 CSR 26-2.033
and the lining or retrofit meets the following
additional requirements:
A. All linings installed or repaired on
or after January 1, 2020, must meet the design
specifications of Underwriters Laboratories
(UL) 1856 Outline of Investigation for
Underground Fuel Tank Internal Retrofit
Systems requirements;
B. Inspections and repairs must be
conducted by a technician who is properly
certified
by
NACE
International
or
International Code Council (ICC);
C. The lining or retrofit is installed
according to manufacturer installation
requirements;
D. An approved national code or standard, including those listed in section (7) of
this rule, is followed;
E. For fiberglass-reinforced plastic
tanks, all linings must be approved by the
tank manufacturer and installed in accordance with the tank manufacturer’s requirements. If the tank manufacturer is no longer
available or willing to repair the tank, the
tank may be lined in accordance with—
(I) The manufacturer’s requirements, or
Substance Storage Tanks
(II) The Fiberglass Tank & Piping
Institute
T-95-1.

Tank and Piping Institute, http://www.fiberglasstankandpipe.com; and
(III) By a technician who is properly
certified by NACE International, International
Code Council (ICC), or the American
Composites Manufacturers Association;
F. All linings must be installed,
inspected, repaired, and maintained in accordance with one (1) of the following:
(I) For UL 1856 Lining systems,
single-walled, co-structural systems and linings installed prior to January 1, 2020:
(a) A lining may only be repaired
if the tank passes an integrity test, including
actual shell thickness readings for steel tanks.
Approved integrity test methods are included
in section (7) of this rule;
(b) A lining may only be
installed if the new lining meets the UL 1856
specifications and the steel tank passes an
integrity test, including actual steel shell
thickness readings. Approved integrity test
methods are included in section (7) of this
rule;
(c) The lining must be internally
inspected at least every five (5) years and
found to be structurally sound with the lining
still performing in accordance with the original design specifications;
(II) For UL 1856 Upgrade systems,
double-walled, co-structural systems:
(a) A lining may only be installed
or repaired if the tank passes an integrity test,
including actual shell thickness readings for
steel tanks. Approved integrity test methods
are included in section (7) of this rule; and
(b) The lining must be internally
inspected at least every five (5) years and
found to be structurally sound with the lining
still performing in accordance with the original design specifications; or
(c) The interstitial lining space is
electronically monitored, with passing sensor
status reports for the most recent twelve (12)
months, in accordance with 10 CSR 26-2.043
subsection (1)(H);
(III) For UL 1856 Structural systems, double-walled, self-structural systems—
(a) The lining must be internally
inspected at least every five (5) years and
found to be structurally sound with the lining
still performing in accordance with the original design specifications; or
(b) The interstitial lining space is
electronically monitored, with passing sensor
status reports for the most recent twelve (12)
months, in accordance with 10 CSR 26-2.043
subsection (1)(H);
G. All interior lining inspection
reports must include photographs of the tank
bottom, a representative tank side wall and a
representative tank end, and documentation
of the interior lining hardness and thickness
readings, in accordance with the evaluation
guidance document used;
(B) Cathodic Protection. A tank may be
upgraded by cathodic protection if the
cathodic protection system meets the requirements of the performance standards for new
UST systems in 10 CSR 26-2.020(1)(A)2.B.–
D. and the integrity of the tank is ensured
using one (1) of the following methods:
1. The tank is internally inspected and
assessed to ensure that the tank is structurally
sound and free of corrosion holes prior to
installing the cathodic protection system.
Structural integrity evaluations must include
steel shell thickness readings and confirmation that the steel shell does not have any
holes or perforations. Approved integrity test
methods are included in section (7) of this
rule;
2. The tank has been installed for less
than ten (10) years and is monitored monthly
for releases in accordance with release detection methods in 10 CSR 26-2.043(1)(E)–(I);
3. The tank has been installed for less
than ten (10) years and is assessed for corrosion holes by conducting two (2) tightness
tests that meet the requirement of release
detection method in 10 CSR 26-2.043(1)(D).
The first tightness test must be conducted
prior to installing the cathodic protection system. The second tightness test must be conducted between three and six (3–6) months
following the first operation of the cathodic
protection system; or
4. The tank is assessed for corrosion
holes by a method that is determined by the
department to prevent releases in a manner
that is no less protective of human health and
the environment than paragraphs (3)(B)1.–3.
of this rule; and
(C) Internal Lining Combined With
Cathodic Protection. A tank may be upgraded
by both internal lining and cathodic protection if—
1. The lining is installed in accordance
with the requirements of 10 CSR 26-2.033;
and
2. The cathodic protection system meets
the
requirements
of
10
CSR
262.020(1)(A)2.B.–D.
(4) Piping Upgrading Requirements. Metal
piping that routinely contains regulated substances and is in contact with an electrolyte,
including, but not limited to, soil, backfill,
and/or water, must be cathodically protected
and must meet the requirements of 10 CSR
26-2.020(1)(B)3.B.–E.
(A) New piping installed at an existing
facility must comply with the requirements of
(5) Spill and Overfill Prevention Equipment.
To prevent spilling and overfilling associated
with product transfer to the UST system, all
existing UST systems must comply with new
UST system spill and overfill prevention
equipment requirements specified in 10 CSR
26-2.020(1)(C) and 10 CSR 26-2.030.
(6) Dispenser Systems. Any new dispenser
installed after July 1, 2017, must have a containment sump beneath it, in accordance with
