         Test Guidelines
         OPPTS 875.1600
         Application exposure
         monitoring data

     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.).

     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:

document format) from the EPA Public Access Gopher  (gopher.epa.gov)

Act (TSCA) (15 U.S.C. 2601).

     (2) Background. The source material used in developing this har-
monized OPPTS test guideline is OPP guideline 236. This guideline should
be used with OPPTS 875.1000.

     (b) Report format. If,  in the  registrant's  opinion, a better format
would result in  a more efficient review by the Agency, it may be used.

     (2) Table of contents. The table of contents should indicate the overall
organization of the report and list the page numbers for the different sec-
tions. Tables, figures, and appendices should be listed separately. (Section

overall summary of the study and mention, at a minimum, the following

     (A) The chemical (use the  name used throughout the report and indi-
cate  the formulation) was applied  according to actual practice to the pri-

     (B) The application rate  in units of active ingredient per unit of area,
volume of spray per unit of area, and total units of active  ingredient han-
dled during each work activity.

     (C) The number of individuals involved in the study, indicating duties

     (D) Indicate unusual problems  (such as  spills, unusual weather,  or
equipment failure) resulting in necessary deviations from the intended test
protocol. Describe the effects  of these deviations in the results of the study.

     (E) Provide a name and phone number of a  contact person in the
event the reviewer has technical questions about the study.

     (4) Materials and methods,  (i) This section should  be  in narrative
form, and should contain (in the following order) all details with regard

to the materials, equipment, experimental design, site description, and pro-
cedures used in conducting the study. The registrant is encouraged to in-
clude drawings (or preferably photographs) of the test site equipment, and
the workers that show the placement of monitoring devices.

     (ii) In this section, the following should be included:
