Indiana Administrative Code
Title 326 - AIR POLLUTION CONTROL DIVISION
Article 8 - VOLATILE ORGANIC COMPOUND RULES
Rule 13 - Sinter Plants
Section 13-2 - Definitions

(1) "Control device" means any equipment that reduces the quantity of a pollutant that is emitted to the air. The device may destroy or secure the pollutant for subsequent recovery. Control devices include, but are not limited to, the following:

(2) "Control measure" means a method to reduce volatile organic compound (VOC) emissions to the atmosphere. The control measure may consist of, but is not limited to, the following:

(3) "Equivalent method" means any method of sampling and analyzing for an air pollutant or any characteristic, such as oil and grease content of the sinter burden, that has been demonstrated to the satisfaction of the commissioner to have a consistent and quantitatively known relationship to the reference method, under specified conditions, for example, approved composite oil and grease samples.

(4) "Exceedance" means the value of the operating parameter or VOC emissions outside the stated boundaries.

(5) "Integrated iron and steel manufacturing sources" means sources that have primary raw material and ironmaking facilities (blast furnaces), steelmaking facilities (basic oxygen furnaces), and finishing mills. Integrated iron and steel manufacturing sources do not include the following:

(6) "Operating day" means a twenty-four (24) hour period between midnight and the following midnight during which the sinter is produced. It is not necessary for the facility to operate continuously for the entire twenty-four (24) hour period. In the event sinter was not produced for twenty-four (24) consecutive hours, a fraction of an operating day is determined by dividing the actual hours of operation by twenty-four (24) hours.

(7) "Operating hour" means any sixty (60) minute period beginning at the start of an hour, for example, 1 a.m. or 2 a.m. through 12 a.m., during which sinter is produced.

(8) "Reference method" means any method of sampling and analyzing for an air pollutant or any characteristic, such as oil and grease content of the sinter burden, as specified in this rule.

(9) "Sinter" means a coherent mass formed by heating raw materials, such as, but not limited to, the following:

(10) "Sinter burden" means the mixture of raw materials prior to use in the sintering process.

(11) "Sinter strand" means a belt that conveys the sinter burden through the sintering process. The burden is conveyed on the strand through a furnace that ignites the fuel in the burden and is then heated under an induced draft to form sinter.

(12) "Sintering process" means the process of igniting fuel in sinter burden and then heating it under an induced draft to form an agglomerate.

(13) "Windboxes" means compartments under the sinter strand that provide for a controlled distribution of combustion air as it is drawn through the sinter bed.
