    (a) For the cokemaking subcategory, the term product means the 
production of coke plus coke breeze.
    (b) The term by-product cokemaking means operations in which coal is 
heated in the absence of air to produce metallurgical coke (furnace coke 
and foundry coke), and the recovery of by-products derived from the 
gases and liquids that are driven from the coal during cokemaking.
    (c) The term cokemaking-non-recovery means cokemaking 
operations for production of metallurgical coke (furnace coke and 
foundry coke) without recovery of by-products. Does not include co-
generation facilities located at non-recovery coke facilities.
    (d) The term coke means a processed form of coal that serves as the 
basic fuel for the smelting of iron ore.
    (1) The term foundry coke means coke produced for foundry 
operations.
    (2) The term furnace coke means coke produced for blast furnace

furnaces associated with steel production.
    (f) The term iron and steel coke plant means by-product cokemaking 
operations other than those at merchant coke plants.
    (g) The term coke oven gas wet desulfurization system means those

    (h) The term coke breeze means fine coke particles.
    (i) The term indirect ammonia recovery system means those systems 
that recover ammonium hydroxide as a by-product from coke oven gases and 
waste ammonia liquors.
    (j) The term iron and steel means those by-product cokemaking 
operations other than merchant cokemaking operations.
    (k) The term merchant means those by-product cokemaking operations 
that provide more than fifty percent of the coke produced to operations, 
industries, or processes other than ironmaking blast furnaces associated 
with steel production.
    (l) The term O&G (as HEM) means total recoverable oil and grease 
measured as n-hexane extractable material.
    (m) The term wet desulfurization system means those systems that 
remove sulfur compounds from coke oven gases and produce a contaminated
