                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 158--DATA REQUIREMENTS FOR REGISTRATION--Table of Contents
 
                      Subpart A--General Provisions
 
Sec. 158.75  Requirements for additional data.

    (a) General policy. The data routinely required by part 158 may not 
be sufficient to permit EPA to evaluate every pesticide product. If the 
information required under this part is not sufficient to evaluate the 
potential of the product to cause unreasonable adverse effects on man or 
the environment, additional data requirements will be imposed. However, 
EPA expects that the information required by this part will be adequate 
in most cases for an assessment of the properties of pesticide.
    (b) Policy on test substance. In general, where the technical grade 
of the active ingredient is specified as the substance to be tested, 
tests may be performed using a technical grade which is substantially 
similar to the technical grade used in the product for which 
registration is sought. In addition to or in lieu of the testing 
required in subparts C and D of this part the Administrator will, on a 
case-by-case basis, require testing to be conducted with:
    (1) An analytical pure grade of an active ingredient, with or 
without radioactive tagging.
    (2) The technical grade of an active ingredient.
    (3) The representative technical grade of an active ingredient.
    (4) An intentionally added inert ingredient in a pesticide product.
    (5) A contaminant or impurity of an active or inert ingredient.
    (6) A plant or animal metabolite or degradation product of an active 
or inert ingredient.
    (7) The end-use pesticide product.
    (8) The end-use pesticide product plus any recommended vehicles and 
adjuvants.
    (9) Any additional substance which could act as a synergist to the 
product for which registration is sought.
    (10) Any combination of substances in paragraphs (b) (1) through (9) 
of this section.
