(1)
Owners and operators must permanently close, in accordance with ARM Title 17,
chapter 56, subchapter 7, any UST system that does not meet the new UST system
performance standards in ARM
17.56.201
or has not been upgraded in accordance with (2) through (4). This requirement
does not apply to previously deferred UST systems described in [17.56.1601 ]
and where an upgrade is required by the department.
(2) All existing UST systems must comply with
one of the following requirements:
(a) new
UST system performance standards under ARM 17.56.201;
(b) the upgrading requirements in (2) through
(4); or
(c) closure requirements
under subchapter 7, including applicable requirements for corrective action
under subchapter 6.
(3)
Steel tanks must be upgraded to meet any one of the following requirements in
accordance with the standards in (6):
(a) a
tank may be upgraded by internal lining if:
(i) the lining is installed in accordance
with the requirements of ARM
17.56.304;
(ii) within ten years after
lining, and every five years thereafter, the lined tank is internally inspected
and found to be structurally sound with the lining still performing in
accordance with original design specifications; and
(iii) if the internal lining is no longer
performing in accordance with original design specifications and cannot be
repaired in accordance with a code of practice developed by a nationally
recognized association or independent testing laboratory, then the lined tank
must be permanently closed in accordance with ARM Title 17, chapter 56,
subchapter 7.
(b) a tank
may be upgraded by cathodic protection if the cathodic protection system meets
the requirements of ARM
17.56.201(1)(a)(ii)(B),
(C), and (D) and the integrity of the tank is
ensured using one of the following methods:
(i) 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; or
(ii) the tank has been installed for less
than ten years and is monitored monthly for releases in accordance with ARM
17.56.407(1)(d)
through (g); or
(iii) the tank has been installed for less
than ten years and is assessed for corrosion holes by conducting two tightness
tests that meet the requirements of ARM
17.56.407(1)(c).
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 months following the first operation of the cathodic protection system;
and
(c) a tank may be
upgraded by both internal lining and cathodic protection if:
(i) the lining is installed in accordance
with the requirements of ARM 17.56.304; and
(ii) the cathodic protection system meets the
requirements of ARM
17.56.201(1)(a)(ii)(B),
(C) and (D).
(4) Metal piping that routinely contains
regulated substances, and is in contact with the ground, must be cathodically
protected in accordance with all of the standards adopted by reference in ARM
17.56.201(6)(s)
through (w) and must meet the requirements of
ARM
17.56.201(1)(b)(ii)(B),
(C), and (D).
(5) 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 ARM
17.56.201(1)(c).
(6) The department adopts and incorporates by
reference the version in effect on January 1, 2018, of the following
