Sec. 79.2  Definitions.

    As used in this part, all terms not defined herein shall have the

by Pub. L. 91-604).
    (b) Administrator means the Administrator of the Environmental 
Protection Agency.
    (c) Fuel means any material which is capable of releasing energy or 
power by combustion or other chemical or physical reaction.
    (d) Fuel manufacturer means any person who, for sale or introduction 
into commerce, produces, manufactures, or imports a fuel or causes or 
directs the alteration of the chemical composition of a bulk fuel, or 
the mixture of chemical compounds in a bulk fuel, by adding to it an 
additive, except:
    (1) A party (other than a fuel refiner or importer) who adds a 
quantity of additive(s) amounting to less than 1.0 percent by volume of 
the resultant additive(s)/fuel mixture is not thereby considered a fuel 
manufacturer.
    (2) A party (other than a fuel refiner or importer) who adds an 
oxygenate compound to fuel in any otherwise allowable amount is not 
thereby considered a fuel manufacturer.
    (e) Additive means any substance, other than one composed solely of

manufactures, or imports an additive for use as an additive and/or sells 
or imports for sale such additive under the person's own name.
    (g) Range of concentration means the highest concentration, the 
lowest concentration, and the average concentration of an additive in a 
fuel.
    (h) Chemical composition means the name and percentage by weight of 
each compound in an additive and the name and percentage by weight of 
each element in an additive.
    (i) Chemical structure means the molecular structure of a compound 
in an additive.
    (j) Impurity means any chemical element present in an additive that 
is not included in the chemical formula or identified in the breakdown 
by element in the chemical composition of such additive.
    (k) Oxygenate compound means an oxygen-containing, ashless organic 
compound, such as an alcohol or ether, which may be used as a fuel or 
fuel additive.
