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:

				resting on either the surface of the liquid or on the leg supports.

(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

(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.
