                   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 section 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 IG at 
40 CFR 136.3(a). 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 IG at 40 
CFR 136.3(a). Pesticide manufacturers may not use the analytical method 
cited in Table IB, Table IC, or Table ID of 40 CFR 136.3(a) to make 
these determinations (except where the method cited in those tables is 
identical to the method specified in Table IG at 40 CFR 136.3(a)). The 
full texts of the analytical methods cited in Table IG at 40 CFR 
136.3(a) 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 IG at 40 CFR 136.3(a) 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.
