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.
