PART 158_DATA REQUIREMENTS FOR REGISTRATION--Table of Contents
 
                    Subpart B_How To Use Data Tables
 
Sec. 158.101  Required vs. conditionally required data.

    (a) Data designated as ``required'' (``R'') for products with a 
given general use pattern are needed by EPA to evaluate the risks or 
benefits of a product having that use pattern unless the data 
requirement has been waived under Sec. 158.45 for that particular 
product or unless the product is covered by a specific exception set 
forth in a note accompanying the requirement.
    (b) Data designated as ``conditionally required'' (``CR'') for 
products with a given general use pattern are needed by EPA to evaluate 
the risks or benefits of a product having that use pattern if the 
product meets the conditions specified in the corresponding notes 
accompanying the data requirements table. As indicated in the notes, the 
determination of whether the data must be submitted is based on the 
product's use pattern, physical or chemical properties, expected 
exposure of nontarget organisms, and/or results of previous testing 
(e.g., tier testing). Applicants must evaluate each applicable note to 
determine whether or not conditionally required data must be submitted 
as indicated by the conditions and criteria specified in the 
accompanying notes unless the Agency has granted a waiver request 
submitted by the registrant in accordance with Sec. 158.45.
    (c) For certain of the required or conditionally required data, the 
``R'' or ``CR'' designations and are enclosed in brackets (i.e., [R], 
[CR]). The brackets designate those data that are required or 
conditionally required to support a product when an experimental use 
permit is being sought. In all other situations (i.e., other than 
support of an experimental use permit), the brackets have no meaning and 
the designations R and CR are equivalent to [R] and [CR], respectively.
