      NECESSITY, FUNCTION,

      Section 1.

Applicability. The provisions of this administrative regulation are applicable

to the following affected facilities commenced before the classification date

defined below: electric submerged arc furnaces which produce silicon metal,

ferrosilicon, calcium silicon, silicomanganese zirconium, ferrochrome silicon,

silvery iron, high-carbon ferrochrome, charge chrome, standard ferromanganese,

silicomanganese, ferromanganese silicon, or calcium carbide; and dust-handling

equipment.

charge" means any material introduced into the electric submerged arc

furnace and may consist of, but is not limited to: ores, slag, carbonaceous

means the more or less completely fused and vitrified matter separated during

the reduction of metal from its ore.

      (5)

cycle" means the time period from completion of a furnace product tap to

the completion of the next consecutive product tap.

      (8) "Tapping

station" means that general area where molten product or slag is removed

from the electric submerged arc furnace.

      (9) "Blowing

tap" means any tap in which an evolution of gas forces or projects jets of

flame or metal sparks beyond the ladle, runner or collection hood.

      (10) "Furnace

power input" means the resistive electrical power consumption of an

electric submerged arc furnace as measured in kilowatts.

      (11)

"Dust-handling equipment" means any equipment used to handle

particulate matter collected by the air pollution control device (and located

at or near such device) serving any electric submerged arc furnace subject to

this administrative regulation.

      (12) "Control

device" means the air pollution control equipment used to remove

particulate matter generated by an electric submerged arc furnace from an

effluent gas stream.

      (13) "Capture

system" means the equipment (including hoods, ducts, fans, dampers, etc.)

used to capture or transport particulate matter generated by an affected

electric submerged arc furnace to the control device.

      (14) "Standard

ferromanganese" means that alloy as defined by ASTM A-99-66(71). (ASTM

designations are filed by reference in 401 KAR 50:015.)

      (15) "Silicomanganese"

means that alloy as defined by ASTM A-483-64(74).

carbide" means material containing seventy (70) to eighty-five (85)

percent calcium carbide by weight.

      (17)

"High-carbon ferrochrome" means that alloy as defined by ASTM A-101-73

grades HC1 through HC6.

      (18) "Charge

chrome" means that alloy containing fifty-two (52) to seventy (70) percent

by weight chromium, five (5) to eight (8) percent by weight carbon, and three

(3) to six (6) percent by weight silicon.

      (19) "Silvery

iron" means any ferrosilicon, as defined by ASTM A-100-69(74), which

contains less than thirty (30) percent silicon.
