                           INTRODUCTION
     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
(OECD).

     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.).

     Final  Guideline Release: This document is available from the U.S.
Government Printing Office, Washington, DC 20402 on The Federal Bul-
letin  Board.   By  modem  dial   202-512-1387,   telnet   and  ftp:

OPPTS 830.1800  Enforcement analytical method.
    (a) Scope—(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 158.180 Enforcement analytical
method.

    (b) Information required. An analytical method suitable for enforce-
ment purposes must be provided for each active ingredient in the product
and for each other ingredient or  impurity  that  is  determined  to  be
lexicologically significant. Copies  of  these methods should be sent  to:
Chief, Analytical Chemistry Laboratory, BARC East, bldg. 306, Beltsville,
MD 20705. Any new  or  changed methods should be  sent to the same
address.
