For the purpose of this subpart:

(a) Except as provided below, the general definitions, abbreviations and methods of analysis set forth in 40 CFR part 401 shall apply to this subpart.

(b) The term anhydrous product shall mean the theoretical product that would result if all water were removed from the actual product.
