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.).
This guideline, along with the others in Series 875.2000 through
875.2900, is being substantially revised for publication in 1997. However,
the current guidelines are still official. Before initiating any studies for
post-application exposure registrants should contact EPA's Occupational
and Residential Exposure Branch (within the Office of Pesticide Programs)
at 703-305-6094.
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 875.2800 Descriptions of human activity.
(a) Scope—(1) Applicability. This guideline is intended to meet test-
ing requirements of the Federal Insecticide, Fungicide, and Rodenticide
Act (FIFRA) (7 U.S.C. 136, et seq.}.
(2) Background. The source material used in developing this har-
monized OPPTS test guideline is OPP guideline 133-1. This guideline
should be used with OPPTS 875.2000 and 875.2900.
(b) Purpose. The purpose of this guideline is to delineate the require-
ments for developing and submitting descriptions of human activities likely
to occur at a site that has been treated with a specific pesticide.
(c) Description of activities. Each brief description should include,
but not necessarily be limited to:
(1) Nature of human activity (e.g. harvesting, thinning, scouting, etc.).
(2) Principal source(s) of exposure (e.g. foliage, soil, air, etc.).
(3) Usual environmental conditions for activity (e.g. hot, humid, cool,
dry, wet, etc.).
(4) Level of physical exertion (e.g. mild, moderate, heavy).
(5) Expected frequency and duration of activity (e.g. number of times
per day or per week, number of hours per day, etc.).
(d) Designation of maximum exposure activity. In connection with
the submittal of descriptions of human activities, the applicant should state
which activity is the most like to result in maximum human exposure to
pesticide residues for each site. In some pesticide use situations, the most
significant human exposure to pesticide residues occurs when harvested
commodities are transferred from the application site and handled (e.g.
sorting of fruits or vegetables). The applicant should include a brief ration-
ale supporting his selection. The activity selected will represent the maxi-
mum expected exposure activity for that specific use, and may be em-
ployed as the exposure standard for future calculations under OPPTS
875.2900 if that guideline is used for calculating a reentry interval.
