Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-15; IC 13-17
Sec. 6.
(a) The owner
or operator of a waste management unit that is subject to requirements under
section 4 or 5 of this rule shall comply with the inspection and monitoring
requirements in subsections (b) through (f). An owner and operator choosing to
comply with a subpart in 40 CFR 63 as allowed in section 5(2) of this rule,
provided it is subject to that subpart, may comply with the inspection
monitoring and record keeping requirements of the subpart instead of the
requirements of this section.
(b)
All seals, covers, closed vent systems, and other equipment used to comply with
section 4 or 5 of this rule (relating to control requirements) shall be
visually inspected for leaks and improper condition initially, semiannually,
and upon repair as specified under this subsection. 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 not later
than fifteen (15) 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. The visual inspection requirements are as follows:
(1) For a wastewater tank equipped with a
fixed roof and vapor control system (closed vent system and control device),
visually inspect the fixed roof, openings, and the closed vent system for
leaks, except for a cover and closed vent system maintained under negative
pressure.
(2) For a wastewater tank
equipped with an internal or external floating roof, visually inspect for the
following improper conditions:
(A) Leaving
open any access door or other opening when the door or opening is not in
use.
(B) The floating roof is not
resting on either the surface of the liquid or on the leg supports.
(C) There is stored liquid on the floating
roof.
(D) A rim seal is detached
from the floating roof.
(E) There
are holes, tears, cracks, or gaps in the rim seal or seal fabric of the
floating roof.
(F) There are
visible gaps between the seal of an internal floating roof and the wall of the
wastewater tank.
(G) Where a
metallic shoe seal is used on an external floating roof, one (1) end of the
metallic shoe does not extend into the stored liquid or one (1) end of the
metallic shoe does not extend a minimum vertical distance of sixty-one (61)
centimeters above the surface of the stored liquid.
(H) A gasket, joint, lid, cover, or door has
a crack or gap or is broken.
(3) For a surface impoundment, visually
inspect the cover and all openings for leaks, except for a cover and closed
vent system maintained under negative pressure.
(4) For a surface impoundment, visually
inspect the following improper conditions:
(A)
Leaving open any access hatch or other opening when the hatch or opening is not
in use.
(B) A joint, lid, cover, or
door has a crack or gap or is broken.
(5) For a portable container, visually
inspect the cover and all openings for leaks.
(6) For a portable container that is located
within an enclosure that is vented by means of a closed vent system to a
control device, visually inspect the enclosure and closed vent system for
leaks, except for an enclosure and closed vent system maintained under negative
pressure.
(7) For a portable
container, visually inspect for the following improper conditions:
(A) Leaving open any access hatch or other
opening when the hatch or opening is not in use.
(B) A cover or door has a gap or crack or is
broken.
(8) For an
individual drain system, visually inspect for the following improper
conditions:
(A) A joint, lid, cover, or door
has a gap, crack, or hole or is broken.
(B) Leaving open any access hatch or other
opening when the hatch or opening is not in use for sampling or removal or for
equipment inspection, maintenance, or repair.
(C) Sufficient water is not present to
properly maintain integrity of water seals.
(D) Drains using tightly-fitted caps or plugs
have caps and plugs that are not in place or not properly installed.
(E) Junction boxes do not have covers in
place or covers have visible gaps, cracks, or holes.
(F) Unburied portion of sewer lines have
cracks or gaps.
(9) 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.
(10) For oil-water separators, visually
inspect fixed roof and all openings for leaks.
(11) For oil-water separators, visually
inspect for the following improper conditions:
(A) Leaving open or ungasketed any access
door or other opening when the door or opening is not in use.
(B) The floating roof is not resting on
either the surface of the liquid or on the leg supports.
(C) There is stored liquid on the floating
roof.
(D) A rim seal is detached
from the floating roof.
(E) There
are holes, tears, or other open spaces in the rim seal or seal fabric of the
floating roof.
(F) A gasket, joint,
lid, cover, or door has a gap or crack or is broken.
(c) For a wastewater tank or
oil-water separator equipped with an external floating roof having primary and
secondary seals used to comply with section 4 or 5 of this rule, the secondary
seal shall be inspected for seal gaps and repaired as follows:
(1) The secondary seal shall be measured for
seal gaps initially, annually, and after repair, as determined under 326 IAC
8-9-5(c)(2).
(2) The accumulated
area of gaps that exceed one-eighth (1/8) inch (thirty-two hundredths (0.32
cm)) in width between the secondary seal and tank wall shall be not greater
than one and zero-tenths (1.0) square inch per foot (twenty-one (21) square
centimeters per meter) of tank diameter.
(3) If the seal gap requirement of
subdivision (2) is not being met, the secondary seal shall be repaired or
replaced within forty-five (45) 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.
(d) The following records shall be maintained
on leaks, improper conditions, and improper seal gaps:
(1) The date on which a leak, improper
condition, or improper seal gap is discovered.
(2) The date on which a first attempt at
repair was made to correct the leak or improper condition.
(3) The date on which a leak, improper
condition, or improper seal gap is repaired.
(e) Monitors shall be installed and
maintained as required by this subsection to measure operational parameters of
any emission control device or other device installed to comply with section 4
or 5 of this rule. The monitoring and parameters shall be sufficient to
demonstrate proper functioning of those devices to design specifications and
include the monitoring and parameters listed in this subsection, as applicable,
except as provided in subdivision (1), as follows:
(1) For an enclosed noncatalytic 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.
(2) For
a catalytic incinerator, continuously monitor and record the temperature of the
gas stream immediately before and after the catalyst bed.
(3) For a condenser (chiller), continuously
monitor and record the temperature of the gas stream at the condenser
exit.
(4) 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, for example, a carbon
canister, the exhaust gas stream shall be monitored daily or at intervals not
greater than twenty percent (20%) 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.
(5) For a flare,
meet the requirements specified in 40 CFR 60.18(b) *.
(6) 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,
such as, the temperature in the column top tray liquid phase at the
downcomer.
(7) For vapor control
systems other than those specified in this subsection, continuously monitor and
record the appropriate operating parameters.
(8) In lieu of the monitoring and parameters
listed in this subsection, other monitoring and parameters may be approved or
required by U.S. EPA. The approval or requirement shall occur when the
department is informed, in writing, that U.S. EPA has no objection to, or
requires, the other monitoring and parameters that are indicated.
(f) For a closed-vent system that
is:
(1) used to comply with section 4 or 5 of
this rule; and
(2) designed to
operate at a pressure below atmospheric pressure;
the closed-vent system shall be equipped with at least one (1) pressure gauge or other pressure measurement device that can be read from a readily accessible location to verify that negative pressure is being maintained in the closed-vent system when the control device is operating.
