Current through Register Vol. 48, No. 9, September 27, 2024
(a)
Owners and operators of UST systems with spill and overfill prevention
equipment and containment sumps used for interstitial monitoring of piping must
meet these requirements to ensure the equipment is operating properly and will
prevent releases to the environment:
(1)
Spill prevention equipment (such as a catchment basin, spill bucket, or other
spill containment device) and containment sumps used for interstitial
monitoring of piping must prevent releases to the environment by meeting one of
the following:
(i) The 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 Section 280.36. Owners and operators must begin meeting paragraph (a)(1)(ii)
of this section and conduct a test within 30 days of discontinuing periodic
monitoring of this equipment; or
(ii) The spill prevention equipment and
containment sumps used for interstitial monitoring of piping are 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:
(A) Requirements developed by the
manufacturer (Note: Owners and operators may use this option only if the
manufacturer has developed requirements);
(B) Code of practice developed by a
nationally recognized association or independent testing laboratory;
or
(C) Requirements determined by
the Department to be no less protective of human health and the environment
than the requirements listed in paragraphs (a)(1)(ii)(A) and (B) of this
section.
(2)
Overfill prevention equipment must be inspected at least once every three
years. At a minimum, the inspection must ensure that overfill prevention
equipment is set to activate at the correct level specified in Section
280.20(c) and will activate when regulated substance reaches that level.
Inspections must be conducted in accordance with one of the criteria in
paragraph (a)(1)(ii)(A) through (C) of this section.
[Note to paragraphs (a)(1)(ii) and (a)(2). The following
code of practice may be used to comply with paragraphs (a)(1)(ii) and (a)(2) of
this section: Petroleum Equipment Institute Publication RP1200, "Recommended
Practices for the Testing and Verification of Spill, Overfill, Leak Detection
and Secondary Containment Equipment at UST Facilities".]
(b) Owners and operators must
begin meeting these requirements as follows:
(1) For UST systems in use on or before May
26, 2017, the initial spill prevention equipment test, containment sump test
and overfill prevention equipment inspection must be conducted not later than
May 26, 2020. All results must be documented using a Department form or a
Department approved form, or submitted in a format as approved by the
Department.
(2) For UST systems
brought into use after May 26, 2017, these requirements apply at installation.
All results must be documented using a Department form or a Department approved
form, or submitted in a format as approved by the Department.
(c) Owners and operators must
maintain records as follows (in accordance with Section 280.34) for spill
prevention equipment, containment sumps used for interstitial monitoring of
piping, and overfill prevention equipment:
(1)
All records of testing or inspection must be documented using a Department
form, a Department approved form, or submitted in a format as directed by the
Department and maintained for three years; and
(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 must be
maintained for as long as the equipment is periodically monitored.
