All terms not defined herein shall have the meaning given
				  them in 326 IAC 14-1, in 326 IAC 14-8, and the following terms shall have the
				  specific meanings provided below.
"Annual coke production" means the coke produced in the
				  batteries connected to the coke by-product recovery plant over a twelve (12)
				  month period. The first twelve (12) month period concludes on the first
				  December 31 that comes at least twelve (12) months after the effective date of
				  326 IAC 14-9, or after the date of initial startup if it is after the effective
				  date.
"In benzene service" means a piece of equipment, other than
				  an exhauster, that either contains or contacts a fluid (liquid or gas) that is
				  at least ten percent (10%) benzene by weight or any exhauster that either
				  contains or contacts a fluid (liquid or gas) at least one percent (1%) benzene
				  by weight as determined by the provisions of 326 IAC 14-9-8(b).
"Coke by-product recovery plant" means any facility designed
				  and operated for the separation and recovery of coal tar derivatives
				  (by-products) evolved from coal during the coking process of a coke oven
				  battery.
"Direct-water final cooler" means a final cooler in which the
				  recirculating water, the cooling medium, is in direct contact with the coke
				  oven gas.
"Equipment" means each pump, valve, exhauster, pressure
				  relief device, sampling connection system, open-ended valve or line, and flange
				  or other connector in benzene service.
"Exhauster" means a fan located between the inlet gas flange
				  and outlet gas flange of the coke oven gas line that provides motive power for
				  coke oven gases.
"Final cooler" means an equipment used to reduce the
				  temperature of the coke oven gas to improve light-oil absorption in the
				  light-oil scrubber.
" Final-cooler cooling tower" means an equipment used to cool
				  the final cooler water.
"Foundry coke" means coke that is produced from raw materials
				  with less than twenty-six percent (26%) volatile material by weight and that is
				  subject to a coking period of twenty-four (24) hours or more.
"Foundry coke by-product recovery plant" means a by-product
				  recovery plant connected to coke batteries whose annual coke production is at
				  least seventy-five percent (75%) foundry coke.
"Furnace coke" means coke produced in by-product ovens that
				  is not foundry coke.
"Furnace coke by-product recovery plant" means a coke
				  by-product recovery plant that is not a foundry coke by-product recovery
				  plant.
" Light-oil sump" means any tank, pit, enclosure, or slop
				  tank in light-oil recovery operations that functions as a wastewater separation
				  device for hydrocarbon liquids on the surface of the water.
"Semiannual" means a six (6) month period; the first
				  semiannual period concludes on the last day of the last full month during the
				  one hundred eighty (180) days following initial startup for new sources; and
				  the first semiannual period concludes on the last day of the last full month
				  during the one hundred eighty (180) days after the promulgation of this rule (
				  326 IAC 14-9 ) for existing sources.
" Tar-bottom final cooler" means a final cooler in which the
				  water, after it has cooled the coke oven gas, is forced through a pool of
				  tar.
" Wash-oil circulation tank" means any vessel that functions
				  to hold the wash oil used in light-oil recovery operations or the wash oil used
				  in the wash-oil final cooler.
" Wash-oil decanter" means any vessel that functions to
				  separate, by gravity, the condensed water from the wash oil received from a
				  wash-oil final cooler or from a light-oil scrubber.
" Wash-oil final cooler" means a final cooler in which
				  wash-oil is used as the cooling medium.
