Indiana Administrative Code › Title 326 - AIR POLLUTION CONTROL DIVISION › Article 6 - PARTICULATE RULES › Rule 6 - Source Specific and Facility Emission Limitations for TSP in Porter County › Section 6-2 - Methods to determine compliance

Current through July 10, 2024
Authority: IC 13-1-1-4; IC 13-7-7
Affected: IC 13-1-1-1; IC 13-1-1-4; IC 13-7
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.
TABLE 1. Fuel Use Equations
(i) For sources with emission limits
				expressed in lb/hr:

Where: Fl through
				  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.,
				Hi) 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:

				written report of any emissions exceeding the applicable limits and the nature
				and cause of the excess emissions, if known.
