          Preliminary Analysis
                  'Public Draft"

     This guideline is one of a series of test guidelines that have been
developed by the Office of Prevention, Pesticides and Toxic Substances,
United States Environmental Protection Agency for use in the testing of
pesticides and toxic substances, and the development of test data that must
be submitted to the Agency for review under Federal regulations.

     The Office of Prevention,  Pesticides and Toxic Substances (OPPTS)
has  developed this guideline through a  process of  harmonization that
blended the testing  guidance and requirements that existed in the  Office
of Pollution Prevention and Toxics  (OPPT) and appeared in Title 40,
Chapter I,  Subchapter R of the Code of Federal Regulations  (CFR), the
Office of Pesticide Programs (OPP) which appeared in publications of the
National Technical  Information Service (NTIS) and the guidelines pub-
lished by the Organization for Economic Cooperation and Development

     The purpose of harmonizing these guidelines into a single  set of
OPPTS  guidelines is to minimize variations among the testing procedures
that must be performed to meet the data requirements of the U. S. Environ-
mental Protection Agency under the Toxic  Substances Control Act (15
U.S.C. 2601) and the Federal Insecticide,  Fungicide and Rodenticide Act
(7U.S.C. I36,etseq.).

     Public Draft Access Information: This draft guideline is part of a
series of related harmonized guidelines that  need to  be considered as a
unit. For copies: These guidelines are available electronically from the

OPPTS 830.1700   Preliminary analysis.
     (a) Scopeó(1) Applicability. This guideline is intended to meet test-
ing  requirements   of both  the  Federal  Insecticide,  Fungicide,   and
Rodenticide Act (FIFRA) (7 U.S.C. 136, et seq.) and the Toxic Substances
Control Act (TSCA) (15 U.S.C. 2601).

     (2) Background. The source material  used in developing this har-
monized OPPTS test guideline is 40 CFR 158.170.

     (b) Information required. (1)  If the product consists solely of the
technical grade active ingredient (TGAI) or is produced by an integrated
system, the applicant must provide a preliminary analysis of each technical
grade of active ingredient contained in the product to identify all impurities
present at 0.1 percent or greater of the TGAI (the Agency recognizes that
this may not be appropriate for certain biologicial pesticides). The prelimi-
nary analysis should be conducted at the  point in the production process
after which no further chemical reactions designed to produce  or purify
the substance are intended.

     (2) Based on the preliminary analysis, a statement of the composition
of the technical grade of active ingredient must be provided. If the tech-
nical grade of active ingredient cannot be isolated, a statement of the com-
position of the practical equivalent of the technical grade of active ingredi-
ent must be submitted.

     (c) Data reporting format.  (1) The  manufacturer's/registrant's/peti-
tioner's reports should include all information necessary to provide com-
plete and accurate topical discussions of the pesticide product.

     (i) Title/cover page. Title page and additional documentation require-
ments  (i.e., requirements for data submission and  procedures for claims
of confidentiality of data) if relevant to the study  report should precede
the content of  the  study formatted below.  These currently proposed re-
quirements are described at 49 FR 37596, September 26,  1984.
