Sec. 2.

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.
