elevator located at any grain processing source that has a permanent grain
storage capacity of thirty-five thousand two hundred (35,200) cubic meters (one
million (1,000,000) U.S. bushels) or more, and any grain terminal elevator that

bushels) or more shall be limited to particulate matter emissions of not
greater than seven-hundredths (0.07) g/dscm (three-hundredths (0.03) grain per
dscf).
(2) All grain elevators
subject to this article shall provide for housekeeping and maintenance
procedures that minimize the opportunity for particulate matter to become
airborne and leave the property, such as the following:
(A) Housekeeping practices shall be conducted
as follows:
(i) Areas to be swept and
maintained shall include, at a minimum, the following:
(AA) General grounds, yard, and other open
areas.
(BB) Floors, decks, hopper
areas, loading areas, dust collectors, and all areas of dust or waste
concentrations.
(CC) Grain driers
with respect to accumulated particulate matter.
(ii) Cleanings and other collected waste
material shall be handled and disposed of so that the area does not generate
fugitive dust.
(iii) Dust from
driveways, access roads, and other areas of travel shall be
controlled.
(iv) Accidental spills
and other accumulations shall be cleaned up as soon as possible but no later
than completion of the day's operation.
(B) Equipment maintenance shall consist of
procedures that eliminate or minimize emissions from equipment or a system
caused by the following:
(i)
Malfunctions.
(ii)
Breakdowns.
(iii) Improper
adjustment.
(iv) Operating above
the rated or designed capacity.
(v)
Not following designed operating specifications.
(vi) Lack of good preventive maintenance
care.
(vii) Lack of critical and
proper spare replacement parts on hand.
(viii) Lack of properly trained and
experienced personnel.
(C) Emissions from the affected areas,
operations, equipment, and systems shall not exceed twenty percent (20%)
opacity as determined under 326 IAC 5-1.
(e) Gray iron foundries shall be limited to
the following:
(1) Any cupola of a gray iron
foundry shall be limited to particulate matter emissions of not greater than
thirty-four hundredths (0.34) g/dscm (fifteen-hundredths (0.15)
grain/dscf).
(2) Any melting
process, excluding any cupola, of a gray iron foundry shall be limited to
particulate matter emissions of not greater than sixteen-hundredths (0.16)
g/dscm (seven-hundredths (0.07) grain/dscf).
(f) Glass container manufacturing furnace
operations shall be limited to particulate matter emissions of not greater than
one (1.0) gram per two (2.0) kilograms of process material (one (1.0) pound per
ton).
(g) Mineral aggregate
operations, where the process is totally enclosed, shall comply with the
requirements in subsection (a). In addition, 326 IAC 2, 326 IAC 5-1, and 326
IAC 6-4 shall apply in all cases to mineral aggregate operations.
(h) Surface coating, reinforced plastic
composites fabricating manufacturing processes, and graphic arts manufacturing
processes shall be controlled by a dry particulate filter, waterwash, or an
equivalent control device, subject to the following:
(1) The source shall operate the control
device in accordance with manufacturer's specifications.
(2) If overspray is visibly detected at the
exhaust or accumulates on the ground, the source shall inspect the control
device and do either of the following no later than four (4) hours after the
observation:
(A) Repair the control device so
that no overspray is visibly detectable at the exhaust or accumulates on the
ground.
(B) Operate equipment so
that no overspray is visibly detectable at the exhaust or accumulates on the
ground.
If overspray is visibly detected, the source shall maintain a
record of the action taken as a result of the inspection, any repairs of the
control device, or change in operations, so that overspray is not visibly
detectable at the exhaust or accumulates on the ground. These records must be
maintained for five (5) years.
(3) A source is exempt from subdivision (2)
if it operates according to a valid permit under:
(A) 326 IAC 2-7;
(B) 326 IAC 2-8; or
(C) 326 IAC 2-9.
(4) Surface coating manufacturing processes
that use less than five (5) gallons of coating per day are exempt from the work
practice standards in subdivisions (1) and (2). At any time the coating
application rate increases to greater than five (5) gallons per day, a control
device must be in place. A manufacturing process that is subject to this
subsection shall remain subject to it even if there is a subsequent decrease in
gallons of coating used.
(i) Based on modeling analyses available to
the commissioner, where it is determined that the limitations in subsections
(a) through (g) are not adequate to achieve and maintain the ambient
particulate air quality standards established by 326 IAC 1-3, the limitations
set forth in this section may be changed for facilities:
(1) having a significant impact on air
quality and located in areas where the ambient particulate standard either is
not attained or will not be maintained without emission limitations in addition
to those set forth in this rule; and
(2) required to comply with the prevention of
significant deterioration requirements of 326 IAC 2.
These limitations shall be established in construction and
operation permits issued in accordance with the procedures set forth in 326 IAC
Sec. 2.
(j) If
the emission limitations established in subsections (a) through (g) for
facilities that were operating or under construction on August 7, 1980, impose
a severe economic hardship on any individual source, then the source may
petition the commissioner for reconsideration of the limitations. If the source
can demonstrate to the commissioner's satisfaction that a severe hardship will
be caused if the applicable requirements in this section are enforced, then
less restrictive emission limitations may be established by the commissioner,
provided the less restrictive limitations will guarantee the attainment and
maintenance of the particulate ambient air quality standards established by 326
IAC 1-3.
