Sec. 4.
Fugitive particulate matter emissions resulting from the emission points specified in this section shall be controlled unless exempted pursuant to 326 IAC 6-5-7(d). All control measures specified in this section shall be considered reasonably available control measures (RCM). The frequency of application for all control measures shall be detailed in each control plan. No control plan shall contain control measures which violate the provisions of the Indiana statutes or the rules of any other state agency.
(a) Paved roads, unpaved
roads, and parking lots. Fugitive particulate matter emissions resulting from
paved roads, unpaved roads, and parking lots shall be controlled unless

of the following measures:
(1) Paved roads
and parking lots:
(A) Cleaning by vacuum
sweeping.
(B) Flushing.
(C) An equivalent alternate
measure.
(2) Unpaved
roads and parking lots:
(A) Paving with a
material such as asphalt or concrete.

(1) Measures to control fugitive particulate
matter emissions shall be required for open aggregate piles consisting of
material such as, but not limited to, sand, gravel, stone, grain, and coal and
which material is finer than two hundred (200) mesh size equal to or greater
than one percent (1%) by weight. Open aggregate material mesh size shall be
determined by the "American Association of State Highway and Transportation
Officials Test Method T27-74," or other equivalent procedures acceptable to the
commissioner.
(2) Fugitive
particulate matter emissions resulting from open aggregate piles consisting of
such material as, but not limited to, sand, gravel, stone, grain, and coal
shall be controlled unless exempted pursuant to
326 IAC
6-5-7(d). Sources may use one or more
of the following measures:
(A) Cleaning the
area around the perimeter of the aggregate piles.
(B) Application of a suitable and effective
oil or other dust suppressant on an as needed basis.
(C) An equivalent alternate
measure.
(c)
Fugitive particulate matter emissions resulting from outdoor conveying of
aggregate material such as, but not limited to, sand, gravel, stone, grain, and
coal, by equipment such as belt conveyors and bucket elevators shall be
controlled unless exempted pursuant to
326 IAC
6-5-7(d). Sources may use one or more
of the following measures:
(1) Enclosing the
conveyor belt totally on the top and sides as needed to minimize visible
emissions. Also, if needed, exhausting emissions to particulate control
equipment during operation of conveyor.
(2) Applying water or suitable and effective
chemical dust suppressant at the feed and/or intermediate points as needed to
minimize visible emissions.
(3) An
equivalent alternate measure.
(d) Fugitive particulate matter emissions
resulting from the transferring of aggregate material shall be controlled
unless exempted pursuant to
326 IAC
6-5-7(d). Sources may use one or more
of the following measures:
(1) Minimizing the
vehicular distance between the transfer points.
(2) Enclosing the transfer points and if
needed exhausting emissions to particulate control equipment during the
operation of the transferring system.
(3) Application of water or suitable and
effective chemical dust suppressant as needed to minimize visible
emissions.
(4) An equivalent
alternate measure.
(e)
Fugitive particulate matter emissions resulting from transportation of
aggregate material by truck, front end loaders, or similar vehicles shall be
controlled unless exempted pursuant to
326 IAC
6-5-7(d). Sources may use one or more
of the following measures:
(1) Use of
completely enclosed vehicles.
(2)
Tarping the vehicle.
(3)
Maintaining the vehicle body in such a condition that prevents any leaks of
aggregate material.
(4) Spraying
the materials in the vehicle with a suitable and effective dust
suppressant.
(5) An alternate
measure.
(f) Fugitive
particulate matter emissions resulting from the loading and unloading
operations of the material from storage facilities such as bins, hoppers, and
silos, onto or out of vehicles, shall be controlled unless exempted pursuant to
326 IAC
6-5-7(d). Sources may use one or more
of the following measures:
(1) Enclosure of
the material loading/unloading area.
(2) Total or partial enclosure of the
facility and exhausting of emissions to particulate collection equipment. Such
equipment shall be approved by the board.
(3) Spraying with water or suitable and
effective chemical dust suppressant as needed to minimize visible
emissions.
(4) Reduction of free
fall distance.
(5) An equivalent
alternate measure.
(g)
Solid waste handling. Fugitive particulate matter emission resulting from
activities involving solid waste (as defined in IC 13-7-1-2(10) [IC
13-7 was repealed by P.L. 1-1996, SECTION 99, effective July 1,
1996.]) disposal shall be controlled unless exempted pursuant to
326 IAC
6-5-7(d). Sources may use one or more
of the following measures:
(1) Hauling
(A) Wet suppression of the material being
transported.
(B) Hauling the
material enclosed or covered.
(C)
Minimizing the free fall distance when unloading from the particulate
collection equipment and/or process equipment onto the hauling
vehicle.
(D) An equivalent
alternate measure.
(2)
Dumping
(A) Applying water or suitable and
effective chemical dust suppressant on an as needed basis to minimize visible
emissions.
(B) Minimizing the free
fall distance of the material.
(C)
An equivalent alternate measure.
(h) Fugitive particulate matter emissions
resulting from material handling operations such as crushing, grinding,
screening, and mixing shall be controlled unless exempted by
326 IAC
6-5-7(d). Sources may use one or more
of the following measures:
(1) Wet
suppression.
(2) Enclosure of
emission source with venting of emissions to a fabric filter.
(3) An equivalent alternate
measure.
(i) Provisions
of this section are applicable in preventing particulate matter from escaping

ventilators, roof monitors, other than a stack as defined in
326 IAC 1-2-74, from sources
subject to
326 IAC 6-5. However, grain
elevators subject to the provisions of this section shall provide for good
housekeeping and good maintenance procedures as set forth in
326 IAC 6.5-1-2(d)(2)
and

6.8-1-2(d)(2).
(1) Fugitive particulate matter emissions
escaping through building openings set forth above shall be controlled unless

that will minimize visible emissions.
(D) An equivalent alternate
measure.
