Inspection and monitoring.
(2) All seals, covers, closed vent systems,

(relating to control requirements) shall be visually inspected for leaks and
improper condition initially, semiannually, and upon repair as specified under
paragraphs (F)(2)(a) to (F)(2)(k) of this rule. If any seal, cover, closed vent
system, or other equipment is found to have a leak or improper condition, a
first attempt at repair shall be completed as soon as possible, but no later
than fifteen calendar days after detection, unless the repair or correction is
technically infeasible without requiring a process unit shutdown, in which case
the repair or correction shall be made at the next process unit shutdown.

seal is used on an external floating roof, one end of the metallic shoe does
not extend into the stored liquid or one end of the metallic shoe does not
extend a minimum vertical distance of sixty-one centimeters above the surface
of the stored liquid.
(viii) A
gasket, joint, lid, cover, or door has a crack or gap, or is

cover, or door has a crack or gap, or is broken.
(e) For a portable container, visually
inspect the cover and all openings for leaks.
(f) For a portable container that is located
within an enclosure that is vented by means of a closed vent system to a

leaks, except for an enclosure and closed vent system maintained under negative
pressure.
(g) For a portable
container, visually inspect for the following improper conditions:
(i) Leaving open any access hatch or other
opening when such hatch or opening is not in use.
(ii) A cover or door has a gap or crack, or
is broken.
(h) For an
individual drain systems, visually inspect for the following improper
conditions:
(i) A joint, lid, cover, or door
has a gap, crack, hole or is broken.
(ii) Leaving open any access hatch or other
opening when such hatch or opening is not in use for sampling or removal, or
for equipment inspection, maintenance, or repair.
(iii) Sufficient water is not present to
properly maintain integrity of water seals.
(iv) Drains using tightly-fitted caps or
plugs have caps and plugs that are not in place or not properly
installed.
(v) Junction boxes do
not have covers in place or covers have visible gaps, cracks, or
holes.
(vi) Unburied portion of
sewer lines have cracks or gaps.
(i) For a junction box vented to a process or
through a closed vent system to a control device, visually inspect for leaks in
the closed vent system.
(j) For
oil-water separators, visually inspect fixed roof and all openings for
leaks.
(k)
Leaving open or ungasketed any access door or other
opening when such door or opening is not in use.
For oil-water separators equipped with a floating roof,
visually inspect for the following improper conditions:
(i) Leaving open or ungasketed any access
door or other opening when such door or opening is not in use.
(ii) The floating roof is not resting on
either the surface of the liquid or on the leg supports.
(iii) There is stored liquid on the floating
roof.
(iv) A rim seal is detached
from the floating roof.
(v) There
are holes, tears, or other open spaces in the rim seal or seal fabric of the
floating roof.
(vi) A gasket,
joint, lid, cover, or door has a gap or crack, or is
broken.
(3)
For a wastewater tank or oil-water separator equipped with an external floating
roof having primary and secondary seals used to comply with paragraph (D) or
(E) of this rule, the secondary seal shall be inspected for seal gaps and
repaired as follows:
(a) The secondary seal
shall be measured for seal gaps initially, annually, and after repair, as
determined under paragraph (I) of rule
3745-21-10
of the Administrative Code.
(b) The
accumulated area of gaps that exceed one-eighth inch ( 0.32 cm) in width
between the secondary seal and tank wall shall be no greater than 1.0 square
inch per foot (twenty-one square centimeters per meter) of tank
diameter.
(c) If the seal gap
requirement of paragraph
(F)(2)(b)
(F)(3)(b) of this rule is not being met, the secondary
seal shall be repaired or replaced within forty-five days after detection of
the improper seal gap unless the repair or correction is technically infeasible
without requiring a process unit shutdown, in which case the repair or
correction shall be made at the next process unit shutdown.
(5) Monitors shall be installed and
maintained as required by this paragraph to measure operational parameters of
any emission control device or other device installed to comply with paragraph
(D) or (E) of this rule. Such monitoring and parameters shall be sufficient to
demonstrate proper functioning of those devices to design specifications, and
include the
following monitoring and parameters
listed in paragraphs (F)(3)(a) to (F)(3)(g) of this
rule, as applicable, except as provided in paragraph (F)(3)(a) of this
rule.
:
(a) For an enclosed non-catalytic combustion
device (including, but not limited to, a thermal incinerator, boiler, or
process heater), continuously monitor and record the temperature of the gas
stream either in the combustion chamber or immediately downstream before any
substantial heat exchange.
(b) For
a catalytic incinerator,
continuously monitor and
record the temperature of the gas stream immediately before and after the
catalyst bed.
one of the following:
(i)
Continuously
monitor and record the temperature of the gas stream immediately before and
after the catalyst bed.
(ii)
If an owner or operator elects to implement an
inspection and maintenance plan for the catalytic incinerator that meets
paragraph (F)(7) of this rule, continuously monitor and record the temperature
of the gas stream immediately before the catalyst bed
only.
(c) For a
condenser (chiller), continuously monitor and record the temperature of the gas
stream at the condenser exit.
(d)
For a carbon adsorber, continuously monitor and record the VOC concentration of
exhaust gas stream to determine if breakthrough has occurred. If the carbon
adsorber does not regenerate the carbon bed directly in the control device
(e.g., a carbon canister), the exhaust gas stream shall be monitored daily or
at intervals no greater than twenty per cent of the design replacement
interval, whichever is greater, or as an alternative to conducting monitoring,
the carbon may be replaced with fresh carbon at a regular predetermined time
interval that is less than the carbon replacement interval that is determined
by the maximum design flow rate and the VOC concentration in the gas stream
vented to the carbon adsorber.
(e)
For a flare, meet the requirements specified in
40 CFR
60.18(b).
(f) For a steam stripper, continuously
monitor and record the steam flow rate, the wastewater feed mass flow rate, and
either the wastewater feed temperature or the column operating temperature
(i.e., the temperature in the column top tray liquid phase at the
downcomer).
(g) For vapor control
systems other than those specified in paragraphs
(F)(15)(a) to (F)(15)(g)
(F)(5)(a) to (F)(5)(f) of this rule, continuously
monitor and record the appropriate operating parameters.
(h) In lieu of the monitoring and parameters
listed in paragraphs
(F)(15)(a) to
(F)(15)(g)
(F)(5)(a) to (F)(5)(g) of this
rule, other monitoring and parameters may be approved or required by the USEPA.
Such approval or requirement shall occur when the Ohio
environmental protection agency
EPA is informed, in writing, that USEPA has no
objection to, or requires, the other monitoring and parameters that are
indicated.
