Sec. 6.
(a) The owner
or operator of a secondary lead smelter shall operate the following process
fugitive emissions sources and fugitive dust sources in a total enclosure that
meets the requirements in subsection (c) that is maintained at negative
pressure at all times and vented to a control device designed to capture lead
particulate:
(1) Smelting furnaces.
(2) Smelting furnace charging
areas.
(3) Lead taps, slag taps,
and molds during tapping.
(4)
Battery breakers.
(5) Refining
kettles, casting areas.
(6)
Dryers.
(7) Agglomerating furnaces
and agglomerating furnace product taps.
(8) Material handling areas for any
lead-bearing materials except those listed in subsection (b).
(9) Areas where dust from fabric filters,
sweepings, or used fabric filters are processed.
(b) The owner or operator of a secondary lead
smelter is not required to maintain a total enclosure in the following areas
unless the area is in a total enclosure described in subsection (a):
(1) Lead ingot product handling
areas.
(2) Stormwater and
wastewater treatment areas.
(3)
Intact battery storage areas.
(4)
Areas where lead-bearing material is stored in closed containers or enclosed
mechanical conveyors.
(5) Areas
where clean battery casing material is handled.
(c) The owner or operator of a secondary lead
smelter shall do the following:
(1) Construct
and operate a total enclosure for the process fugitive emissions sources and
fugitive dust sources listed in subsection (a) that is free of cracks, gaps,
corrosion, or other deterioration that could allow lead-bearing material to be
released from the primary barrier.
(2) Put measures in place to prevent the
tracking of lead-bearing material out of the plant by personnel or by equipment
used in handling the material.
(3)
Designate an area to decontaminate equipment and collect and properly manage
any rinsate.
(4) Ventilate the
total enclosure for the process fugitive emissions sources and fugitive dust
sources listed in subsection (a) continuously to ensure negative pressure
values of at least thirteen-thousandths (0.013) millimeters of mercury
(seven-thousandths (0.007) inches of water).
(5) Maintain an inward flow of air through
all natural draft openings of the total enclosure.
(6) Inspect total enclosures and structures
that contain any lead-bearing material at least once per month.
(7) Repair any gaps, breaks, separations,
leak points, or other possible routes for emissions of lead to the atmosphere
within one (1) week of identification unless the owner or operator of a
secondary lead smelter receives approval for an extension from the department
and U.S. EPA before the repair period is exceeded.
