                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 455--PESTICIDE CHEMICALS--Table of Contents
 
            Subpart D--Test Methods for Pesticide Pollutants
 
Sec. 455.50  Identification of test procedures.


    The pesticide active ingredients to which this regulation applies 
and for which effluent limitations guidelines and standards are 
specified in this part are named, together with the Chemical Abstracts 
Service (CAS) number (provided to assist in identifying the pesticide 
active ingredient only) and analytical method(s) designation(s) in table 
7 of this part. Except as provided in 40 CFR 136.5, the discharge 
parameter values required under the Clean Water Act must be determined 
by one of the analytical methods cited and described in table 7 of this 
part. Pesticide manufacturers may not use the analytical method cited in 
table 1B, table 1C, or table 1D of 40 CFR part 136 to make these 
determinations (except where the method cited in those tables is 
identical to the method specified in table 7 of this part). The full 
texts of the analytical methods cited in table 7 of this part are 
contained in the ``Methods For The Determination of Nonconventional 
Pesticides In Municipal and Industrial Wastewater, Volume I,'' EPA 821-
R-93-010A (August 1993 Revision I) and ``Volume II'', EPA 821-R-93-010B 
(August 1993) (the ``Compendium''). Each pesticide chemical manufacturer 
that is required to determine discharge parameter values under this part 
using one of the analytical methods cited in table 7 of this part must 
request in writing a copy of the Compendium from the permit authority or 
local control authority (as applicable) prior to determining such 
discharge parameter values, unless the manufacturer already has a copy.
