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.
