Sec. 10.
(a) The
following definitions apply throughout this section:
(1) "Coal" means all solid fossil fuels
classified by ASTM designation D388-88* as:
(A) anthracite;
(B) bituminous;
(C) subbituminous; or
(D) lignite.
(2) "Coal mine" means an individual
excavation site from which coal is removed by surface or underground mining
operations.
(3) "Coal preparation
plant" means any facility (excluding underground and surface mining operations)
that prepares coal by one (1) or more of the following processes:
(A) Breaking.
(B) Crushing.
(C) Screening.
(D) Wet or dry cleaning.
(E) Thermal drying.
(4) "Coal processing and conveying equipment"
means any machinery used to reduce the size of coal or to separate coal from
refuse, and the equipment used to convey coal to or remove coal and refuse from
the machinery. This includes, but is not limited to, the following:
(A) Breakers.
(B) Crushers.
(C) Screens.
(D) Conveyor belts.
(5) "Collocated source" means any coal
preparation facility and coal mine that are:
(A) located on one (1) piece of property or
on contiguous or adjacent properties; and
(B) owned or operated by the same person (or
by persons under common control).
(6) "Material transfer" means the transfer of
material:
(A) from:
(i) process equipment onto the
ground;
(ii) the ground into
hauling equipment;
(iii) hauling
equipment onto a storage pile; or
(iv) a storage pile into hauling equipment
for transport; or
(B)
into an initial hopper for further processing.
(7) "Refuse" means the portion of mined coal
that is rejected by the preparation plant as unsalable.
(8) "Thermal dryer" means any facility in
which the moisture content of bituminous coal is reduced by contact with a
heated gas stream that is exhausted to the air.
(b) Any coal preparation plant, coal mine, or
collocated source may elect to be subject to this section by complying with the
requirements of section 1 of this rule and meeting the following conditions:
(1) Coal preparation plants that do not
utilize thermal dryers or pneumatic coal cleaning equipment and do not emit
particulate matter less than ten microns (PM10) in
excess of or equal to one hundred (100) tons per year, including fugitive
particulate emissions, shall limit the total annual tons of coal shipped to
less than five million (5,000,000) tons per year and must comply with the
following:
(A) Each coal preparation plant
shall maintain at the site total annual throughput records for the previous
twelve (12) months on a monthly rolling total, and records shall be kept for a
minimum of five (5) years.
(B) The
screening, crushing, and conveying operations at a coal preparation plant shall
be enclosed, unless a wet suppression system is used, such that visible
emissions shall not exceed an average of twenty percent (20%) opacity in
twenty-four (24) consecutive readings in a six (6) minute period using
procedures in 40 CFR 60, Appendix A, Method 9**.
(2) Fugitive particulate emissions at a coal
preparation plant, coal mine, or collocated source from open storage piles,
unpaved roadways, or batch transfer operations shall be controlled by applying
water or other approved dust suppressant on an as needed basis such that the
following visible emission conditions are met:
(A) Visible emissions from storage piles
shall not exceed twenty percent (20%) in twenty-four (24) consecutive readings
in a six (6) minute period. This limitation shall not apply during periods when
application of control measures are ineffective or unreasonable due to
sustained high wind speeds. The opacity shall be determined using 40 CFR 60,
Appendix A, Method 9**, except that the opacity shall be observed at the point
of maximum opacity. The observer shall stand at least fifteen (15) feet, but
not more than one-fourth (1/4) mile, from the plume and at approximately right
angles to the plume.
(B) Visible
emissions from unpaved roads shall not exceed an average instantaneous opacity
of twenty percent (20%). The average instantaneous opacity shall be the average
of twelve (12) instantaneous opacity readings, taken for four (4) vehicle
passes, consisting of three (3) opacity readings for each vehicle pass. The
three (3) opacity readings for each vehicle pass shall be taken as follows:
(i) The first will be taken at the time of
emission generation.
(ii) The
second will be taken five (5) seconds after the first.
(iii) The third will be taken five (5)
seconds after the second or ten (10) seconds after the first.
The three (3) readings shall be taken at approximately four
(4) feet from the surface at the point of maximum opacity. The observer shall
stand at least fifteen (15) feet, but not more than one-fourth (1/4) mile, from
the plume and at approximately right angles to the plume.
(C) Visible emissions from
material transfer operations shall not exceed an average instantaneous opacity
of twenty percent (20%). The average instantaneous opacity shall be the average
of three (3) opacity readings taken five (5) seconds, ten (10) seconds, and
fifteen (15) seconds after the end of one (1) material loading or unloading
operation. The three (3) readings shall be taken at the point of maximum
opacity. The observer shall stand at least fifteen (15) feet, but not more than
one-fourth (1/4) mile, from the plume and at approximately right angles to the
plume.
(3) All visible
emission readings shall be performed by a qualified observer as defined in 326
IAC 1-2-62.
(4) Fugitive
particulate emissions at a coal preparation plant, coal mine, or collocated
source shall not escape beyond the property line or boundaries of the property,
right-of-way, or easement on which the source is located, pursuant to 326 IAC
6-4.
(5) The annual notice required
by section 1(d) of this rule shall also include the legal description of the
source's location.
(6) Upon
billing, each coal preparation plant, coal mine, or collocated source shall
pay:
(A) an application fee in accordance
with 326 IAC 2-1.1-7(g); and
(B) an
annual fee in accordance with 326 IAC 2-1.1-7(g)(4).
