a) The owner or
operator must inspect the following, where present, at least once each
operating day, data gathered from monitoring and leak detection equipment
(e.g., pressure or temperature gauges, monitoring wells, etc.) to ensure that
the tank system is being operated according to its design.
b) Except as noted under subsection (c), the
owner or operator must inspect the following at least once each operating day:
1) Overfill/spill control equipment (e.g.,
waste-feed cutoff systems, bypass systems, and drainage systems) to ensure that
it is in good working order;
2)
Above ground portions of the tank system, if any, to detect corrosion or
releases of waste; and
3) The
construction materials and the area immediately surrounding the externally
accessible portion of the tank system, including the secondary containment
system (e.g., dikes) to detect erosion or signs of releases of hazardous waste
(e.g., wet spots, dead vegetation, etc.).
BOARD NOTE: Section
725.115(c)
requires the owner or operator to remedy any deterioration or malfunction the
owner or operator finds. Section
725.296
requires the owner or operator to notify the Agency within 24 hours of
confirming a release. Also, federal 40 CFR 302 may require the owner or
operator to notify the National Response Center of a release.
c) The owner or operator of a tank
system that either uses leak detection equipment to alert facility personnel to
leaks or implements established workplace practices to ensure leaks are
promptly identified must inspect at least weekly those areas described in
subsections (b)(1) through (b)(3). Use of the alternate inspection schedule
must be documented in the facility's operating record. This documentation must
include a description of the established workplace practices at the
facility.
d) This subsection (d)
corresponds with
40
CFR
265.195(d), which USEPA
has removed and marked "reserved". This statement maintains structural
consistency with the corresponding federal requirements.
e) Ancillary equipment that is not provided
with secondary containment, as described in Section
725.293(f)(1)
through (f)(4), must be inspected at least
once each operating day.
f) The
owner or operator must inspect cathodic protection systems, if present,
according to, at a minimum, the following schedule to ensure that they are
functioning properly:
1) The proper operation
of the cathodic protection system must be confirmed within six months after
initial installation, and annually thereafter; and
2) All sources of impressed current must be
inspected or tested, as appropriate, at least every other month.
BOARD NOTE: The practices described in "Control of External
Corrosion on Metallic Buried, Partially Buried, or Submerged Liquid Storage
Systems", NACE Recommended Practice RP0285-85, or "Cathodic Protection of
Underground Petroleum Storage Tanks and Piping Systems", API Recommended
Practice 1632, each incorporated by reference in 35 Ill. Adm. Code
720.111(a),
may be used, where applicable, as guidelines in maintaining and inspecting
cathodic protection systems.
g) The owner or operator must document in the
operating record of the facility an inspection of those items in subsections
(a) and (b).
