    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and in subpart A.
    Ammonium sulfate dryer means a unit or vessel into which ammonium

the product using a heated gas stream. The unit includes foundations, 
superstructure, material charger systems, exhaust systems, and integral 
control systems and instrumentation.
    Ammonium sulfate feed material streams means the sulfuric acid feed 
stream to the reactor/crystallizer for synthetic and coke oven by-
product ammonium sulfate manufacturing plants; and means the total or 
combined feed streams (the oximation ammonium sulfate stream and the 
rearrangement reaction ammonium sulfate stream) to the crystallizer 
stage, prior to any recycle streams.
    Ammonium sulfate manufacturing plant means any plant which produces 
ammonium sulfate.
    Caprolactam by-product ammonium sulfate manufacturing plant means 
any plant which produces ammonium sulfate as a by-product from process 
streams generated during caprolactam manufacture.
    Coke oven by-product ammonium sulfate manufacturing plant means any

plant which produces ammonium sulfate by reacting sulfuric acid with 
ammonia recovered as a by-product from the manufacture of coke.
    Synthetic ammonium sulfate manufacturing plant means any plant which 
produces ammonium sulfate by direct combination of ammonia and sulfuric 
acid.
