Current through October 23, 2024

Section 326 IAC 6.8-10-2 - Definitions

Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11

Affected: IC 13-15; IC 13-17

Sec. 2.

The following definitions apply throughout this rule:

(1) "Affected facilities" means the sources of fugitive emissions listed in section 1(a) of this rule.

(2) "Batch transfer" means transfer of material onto or out of storage piles by front end loaders, trucks, or cranes.

(3) "Capacity" means the sum of all throughputs to the first introduction point of all the processing lines on a plant property.

(4) "Capture system" means the equipment used to capture and transport particulate matter generated by one (1) or more process equipment to a control device, including the following:

(A) Enclosures.

(B) Hoods.

(C) Ducts.

(D) Fans.

(E) Dampers.

(5) "Continuous transfer" means transfer of material onto or out of storage piles by conveyor.

(6) "Control device" means the air pollution control equipment used to reduce particulate matter emissions released to the atmosphere.

(7) "Dust handling equipment" means the equipment used to handle dust collected by control equipment, such as, but not limited to, a conveyor used to transfer dust from a control equipment hopper to a temporary storage container. A truck is an example of a temporary storage container. Both a conveyor and temporary storage container, in this case, are dust handling equipment.

(8) "Exposed areas" means unused areas on plant property that cannot be defined as a paved or unpaved road or parking lot, storage pile, or associated area that have the potential to emit particulate emissions by wind action.

(9) "Fugitive particulate matter" means any particulate matter emitted into the atmosphere other than through a stack.

(10) "Inplant transportation" means transportation of material on plant transportation routes, such as railroads and plant roads, in equipment such as trucks, railroad cars, front end loaders, conveyors, and skip hoists. The inplant transportation might be from:

(A) one (1) process to another;

(B) process equipment to waste disposal and reclamation sites; or

(C) one (1) storage pile to another.

This includes, for example, hauling of slag from slag pits to the slag processing facility on the plant property.

(11) "Material" means raw process material, byproduct, intermediate product, waste product, final product, and dust collected by control equipment, having proportion of loose, dry dust equal to or greater than five-tenths percent (0.5%) as measured by the ASTM C-136 method*, having potential to emit particulate emissions when disturbed by transfer, processing, and transportation activities defined in this rule. Material may include the following:

(A) Sand.

(B) Limestone.

(C) Coal.

(D) Gypsum.

(E) Slag.

(F) Gravel.

(G) Clay.

(H) Cement.

(I) Ores.

(J) Grain.

(12) "Material processing facilities" means the equipment, or the combination of different types of equipment, used to process material for use in the plant or for commercial sale. The following sources are examples of these types of facilities:

(A) Power generation plants.

(B) Portland cement manufacturing plants.

(C) Asphalt concrete manufacturing plants.

(D) Concrete manufacturing plants.

(E) Lime manufacturing plants.

(F) Iron and steel manufacturing plants, which include blast furnaces and basic oxygen furnaces.

(G) Sinter plants.

(H) Coal and coke preparation plants.

(I) Slag processing plants.

(J) Brick manufacturing plants.

(K) Grain processing elevators.

(L) Food and feed manufacturing plants.

Equipment includes initial crusher, screen, grinder, mixer, dryer, belt conveyor, bucket elevator, bagging operation, storage bin, and truck or railroad car loading station.

(13) "Material transfer" means the transfer of material:

(A) from process equipment onto the ground;

(B) from the ground into hauling equipment;

(C) from hauling equipment onto a storage pile;

(D) from a storage pile into hauling equipment for transport; or

(E) into an initial hopper for further processing.

Dumping of slag from blast furnaces or basic oxygen furnaces into the slag pits and subsequent transfer to the hauling vehicle and initial hopper at the slag processing facility is an example of material transfer.

(14) "Paved road" means an asphalt or concrete surfaced thoroughfare or right-of-way designed or used for vehicular traffic.

(15) "Processing line" means material processing equipment connected by a conveying system. The term does not include transfer from a conveyor to a storage pile.

(16) "Silt content" means the mass of an aggregate sample smaller than seventy-five (75) microns in diameter as determined by dry sieving. Silt content may be determined by using the procedures in AP-42 "Silt Analysis" Appendix C.2.3, Fifth Edition, January 1995**, Supplements A through G, December 2000***.

(17) "Stack emissions" means the particulate matter that is released to the atmosphere from a confined opening like the exit of a control device or a chimney.

(18) "Storage pile" means any outdoor storage on a source's property of material as defined in subdivision (11).

(19) "Surface silt loading" means the mass of loose surface dust on a paved road, per length of road, as determined by dry vacuuming. Surface silt loading may be determined by using the procedures specified in the U.S. EPA guideline document Iron and Steel Plant Open Source Fugitive Emission Evaluation", U.S. EPA 600/ 2-79-103, Appendix B****.

(20) "Transfer point" means a point in a conveying operation where the material is transferred to or from a belt conveyor, except where the material is being transferred to a storage pile.

(21) "Unpaved road" means a thoroughfare or right-of-way other than a paved road designed or used for vehicular traffic.

(22) "Vent" means an opening through which there is mechanically induced airflow for the purpose of exhausting air carrying particulate matter emissions from one (1) or more items of material processing equipment from a building.
