Sec. 2.
(a) This
section applies to the emission limitations contained in
326 IAC 6-6-4.
(b) All lb/ton (pound per ton) emission
factor limits are expressed as "pounds of particulate emissions per ton of
product" unless otherwise stated. By-products which may be sold as product
shall not be included under the term "product."
(c) All lb/MMBtu (pounds per million Btu)
emission factor limits are expressed as "pounds of particulate emissions per
million Btu of fuel(s) fired in the source" unless otherwise stated.
(d) Fuel usage data may be used to determine
compliance for any non-fossil-fuel-fired source and any fossil fuel-fired
source that does not have a gas cleaning device which is used to reduce
particulate emissions to the atmosphere, provided that the following procedures
are followed:
(1) The owner/operator shall
collect fuel usage data at least once per month and shall record them in a log
which is readily available for inspection. Records must be retained for two (2)
years from the date of collection.
(2) The following fuel usage data shall be
recorded for each source monthly:
(A) number
of hours in operation;
(B) cubic
feet of each gaseous fuel fired;
(C) gallons of each liquid fuel
fired;
(D) pounds of each solid
fuel fired.
(3)
Compliance shall be determined using the equations in Table 1. An equivalent
alternate method may be used with prior approval of the commissioner.

Fi = the quantities (e.g., million cu. ft.) of each fuel
type used in one (1) month.
El through Ei =
the emission factors (e.g., lb/million cu.ft.) corresponding to the fuel types
used; the most recent emissions factors obtained by the procedures required by
subdivision (d)(4) of this section shall be used.
Tt = Total emissions in lbs/hr.
(ii) For sources with short-term
emission limits expressed in lb/MMBtu:

Where: Fl through
Fi = the quantities (e.g., million cu.ft.) of each fuel
type used in one (1) month.
Hl through Hi =
the heat content factors (e.g., BTU/cu.ft.) corresponding to the fuel types
used; the most recent heat content factors obtained by the procedures required
by subdivision (d)(4) of this section shall be used.
El through Ei =
the emission factors (e.g., lb/million cu.ft.) corresponding to the fuel types
used; the most recent emissions factors obtained by the procedures required by
subdivision (d)(4) of this section shall be used.
Th = Total emissions in
lbs/MMBtu.
(4)
Once each calendar quarter the owner/operator shall conduct sampling and
analysis to determine the heat content factors (i.e.,
H
i) contained in the equations set forth in this
subsection.
Once each calendar quarter the owner/operator shall conduct
sampling and analysis to determine the sulfur content of No. 6 fuel oil and
shall calculate the emission factor for this fuel using the following
equation:
(10) S + 3 = EF
Where EF = the particulate emission factor for No. 6 fuel oil
(i.e., lb/1,000 gal.)
S = percent sulfur in the fuel, by weight. The sampling and
test methodologies used must be approved by the commissioner. The most recent
No. 6 fuel oil emission factor obtained using the above procedure shall be used
in emission rate calculations. The emission factors used for fuels other than
No. 6 fuel oil shall be as follows:
| Fuel |
Emission Factor |
| Natural Gas |
5.0 lbs per MM SCF |
| Blast Furnace Gas |
1.5 lbs per MM SCF |
| Coke Oven Gas |
6.6 lbs per MM SCF |
| Propane |
0.44 lbs per 1,000 gallons |
| Waste Oil |
8.8 lbs per 1,000 gallons |
| No. 2 Fuel Oil |
2.0 lbs per 1,000 gallons |
(5)
Within thirty (30) days of the end of each monthly monitoring period the
owner/operator shall calculate the pounds of particulate matter emitted per
hour, or lb/MMBtu as applicable from each source using the equation given in
this subsection. Results of these calculations must be retained for two (2)
years. An equivalent alternate method and/or frequency may be used with the
prior approval of the commissioner.
(6) A list of those sources which will rely
on fuel usage data to determine compliance with their emission limitations is
shown in Table 2:

(7) Within thirty (30) days of the end of
each calendar quarter the owner/operator shall submit to the commissioner a
written report of any emissions exceeding the applicable limits and the nature
and cause of the excess emissions, if known.
(e) When required by the commissioner the
owner/operator shall make any stack modifications necessary to permit a stack
test in accordance with 40 CFR
60, Appendix A, Methods 1-5.
(1) List of sources for which stack tests are
required to determine compliance with particulate emission limitations
The BOF shop: Nos. 1 and 2 Vessel Scrubber stacks (three (3)
stacks) shall be tested once in each four (4) year period.
The sinter plant windbox scrubber stack shall be tested once
in each two (2) year period.
The sinter plant dedusting baghouse stack shall be tested
once in each two (2) year period.
The coke oven battery nos. 1 and 2 pushing emissions control
system stacks (two (2) stacks) shall be tested once in each four (4) year
period.
(f) If a
compliance determination based on fuel usage data does not agree with a
compliance determination based on stack test data, the determination based on
stack test data shall govern. Stack test data may reflect a total sampling time
of less than twenty-four (24) hours and be acceptable for such a compliance
determination.
(g) Application for
an alternative source-specific opacity limit may not be based on fuel usage
data.
(h) Stack tests of
fossil-fuel-fired sources shall include soot blowing at a frequency that is
representative of normal operations.
(i) Compliance with the coke quenching water
quality limits shall be determined according to the procedures given below:
(1) The water as applied to the coke shall be
sampled once per calendar quarter. Samples shall be collected once per day per
tower for five (5) consecutive days and shall be composited into one (1) sample
for each tower.
(2) Each composite
sample shall be analyzed for total dissolved solids (TDS), in accordance with
ASTM D-1888-78, Method A or an equivalent method approved by the commissioner,
with the results expressed in milligrams per liter (mg/l).
(3) Compliance shall be determined on the
basis of the results of the composite sample for each tower. Alternate testing
and/or analysis intervals may be used with prior approval of the
board.
(j) Compliance
with applicable particulate emission limitations for stack sources for which
compliance is not based on fuel monitoring shall be determined on the basis of
opacity observations performed in accordance with
326 IAC 5-1. The following
exceptions to
326 IAC 5-1 shall apply:
(1) When observing visible emissions, the
observer may choose not to position himself with the sun in the one hundred
forty (140) degree sector at his back provided the day is cloudy or overcast,
causing the sun to be hidden from the observer.
(2) When determining an average opacity, the
readings immediately preceding and following any interference or exceptions, as
allowed by the limit, shall be deemed consecutive.
(3) Compliance with emission limits for
baghouse discharges shall be determined as follows:
Visible emissions in excess of an average twenty percent
(20%) opacity in twenty-four (24) consecutive readings shall constitute
evidence of a violation of the applicable particulate emission limit. The
commissioner may require a stack test performed in accordance with 40 CFR 60,
Methods 1-5, to verify the mass emission rate.
(4) The commissioner may require stack tests
in addition to the specific requirements of this rule (
326 IAC
6-6). When such testing is required, the
owner/operator shall permit the performance of stack tests in accordance with
40 CFR
60, Appendix A, Methods 1-5.
(k) Alternative opacity as provided for in
326 IAC 5-1-5 shall not apply to
groups of sources collectively subject to a single mass emission
limit.
(l) When compliance testing
is required for those groups of sources collectively subject to a single mass
emission limit, the testing need not be conducted simultaneously.
(m) Any revision to this rule (
326 IAC
6-6) and the technical support document must be
submitted to the U.S. EPA as a revision of the state implementation
plan.
(n) In determining compliance
for coke oven pushing, charging, oven door leaks, and charging lid and off-take
leaks, the requirements specified under
326 IAC 11-3 shall govern. The
mass emission limits for these sources given in this rule (
326 IAC
6-6) shall be used only for the purpose of determining
emission offsets resulting from source shutdown.
(o) Testing required by the commissioner to
determine the amount of particulate matter emitted from any non-stack source or
facility subject to the requirements of this rule (
326 IAC
6-6) shall be conducted in accordance with procedures
approved by the commissioner.
