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 guideline 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 860.1560 Reasonable grounds in support of the petition.
(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 Federal Food,
Drug, and Cosmetic Act (FFDCA) (21 U.S.C. 301, et seq.}.
(2) Background. The source material used in developing this har-
monized OPPTS guideline is OPP 171-7 Reasonable Grounds in Support
of the Petition (Pesticide Assessment Guidelines, Subdivision O: Residue
Chemistry, EPA Report 540/9-82-023, October 1982). This OPPTS guide-
line should be used in conjunction with OPPTS 860.1000, Background.
(b) Reasonable grounds in support of the petition—section G of
a petition. (1) The petitioner should present the rationale of how the resi-
due data support the proposed tolerance. The presentation should include:
(i) Brief discussions on the adequacy of the analytical method with
respect to sensitivity and determination of the total toxic residue.
(ii) An explanation of any aberrant residue values reported.
(iii) An explanation for the omission or substitution of requirements
set forth in these guidelines.
(iv) Any other residue considerations pertinent to the proposed use.
(v) Where appropriate, a discussion should be furnished on the status
of other components of the formulation.
(2) In those instances where the dietary risk from use of the pesticide
is likely to be unacceptable, assuming tolerance level residues on the entire
crop, the petitioner should provide any information or data that could be
used to estimate a more realistic dietary exposure. In the case of concerns
with chronic risk, determination of the average residue obtained in crop
field trials would be useful. Also, information on actual or projected mar-
ket shares for existing or proposed uses, respectively, can be submitted
for review by OPP's Biological and Economic Analysis Division.
