DATA REPORTING
FOREWORD
The Data Reporting Guidelines are addenda to the Pesticide Assessment
puidelines (Subdivision O), designed primarily to aid the petitioner/registrant
in generating reports compatible with the Environmental Protection Agency's
review process. They were intended also to clarify ambiguities in the
Interpretation of the existing Pesticide Assessment Guidelines .^/ The Data
Reporting Guidelines are not intended to introduce new data requirements or
-evisions to the Pesticide Assessment Guidelines, nor are they intended for
jse by Agency reviewers as a mere checklist. While following the Data Reporting
luidelines is not mandatory, data submitters are encouraged to submit complete
•eports which can be efficiently reviewed by the Agency. The Agency realizes
here are sections in the Data Reporting Guidelines which do not apply in all
ases. Therefore, registrants should exercise judgment in deciding vhich
ortions are germane to a specific data submission.
, This guidance pertains to the substance of the data report. PR Notice
6-5, effective on November 1, 1986 (available from the Registration Support
id Emergency Response Branch, Office of Pesticide Programs, US EPA), pertains
3 the physical formating of reports (which are referred to as "studies")
id sutmittal packages. Some of the requirements in PR Notice 86-5 are
i inflatory.
i The Data Reporting Guideline on Specialty Applications is divided into
1 nree parts: (I) Classification of Seed Treatments and Treatment of Crops
C -own for Seed Use Only as Non-Food or Pood Uses? (II) Postharvest Fumigation
c : Crops and Processed Foods and Feeds; (III) Post-harvest Treatment (Except
I migation) of Crops and Processed Foods and Feeds. Each part gives the
i rmat/outline recommended by the Agency to be used by the petitioner/
r gistrant for reports on the particular specialty application study.
RESPONSE TO PUBLIC COMMENTS
The purpose of this section is to acknowledge and address the concerns
expressed in the letters of comments received by the Agency in response to
In addition, Residue Chemistry Standard Evaluation Procedures, designed to
aid Agency reviewers in their evaluations of pesticide residue data, are
available. They provide a nore thorough clarification of the existing
Pesticide Assessment Guidelines.

the public notice in the FEDERAL REGISTER of October 15, 1986 (51 FR 36753).
The only conment received concerning these guidelines was that the guidelines
should not contain technical details on why the test is necessary, how it should
be run and how the data will be evaluated; these should be covered by the
Pesticide Assessment Guidelines and Standard Evaluation Procedures (SEPs). The
Agency has included the introductory materials as a convenience to data
submitters and to clarify relevant sections in the Pesticide Assessment Guidelines
of difficulty for some registrants.
-------
Classification of Seed Treatments and Treatment of Crops
Grown for Seed Only as Non-Food or Pood Uses
Treatment of Crops Grown for__Seed Use Only
For the treatanent of crops grown for seed use only to be classified as a
non-food use, the following requirements must be met: (1) the seed itself or
its sprouts are not raw agricultural conmodities ;£/ 2) there is no livelihood
of residues in crops grown from harvested seed; (3) subsequent to treatment,
all parts of the crop are not fit for human or animal consumption. Details of
these requirements and any exceptions are given in Part I of the Standard
Evaluation Procedure for Specialty Applications.^/ If the treatment of the
crop grown for seed use only is classified as a non-food use, no residue
studies are needed. If the treatment of the crop grown for seed use only is
classified as a food use, metabolism and crop field studies are needed. The
formats for the metabolism and crop field studies^/ are addressed in separate
Data Reporting Guideline documents being developed concurrently, and the
registrant/petitioner is referred to those Data Reporting Guidelines when the
treatment of crops grown for seed use only is classified as a food use.
Seed Treatments
For seed treatments to be classified as a non-food use, data fron a
radiotracer study are needed demonstrating no uptake of radioactivity to the
aerial portion and edible root (both human and livestock consumption) portion
of the crop.£/ If the radiotracer study demonstrates that the particular seed
treatment is a non-food use, no further studies are needed. If the seed
treatment is classified as a food use, plant metabolism and crop field studies^/
are needed, and the registrant is referred to the Data Reporting Guidelines
for those studies.
2/ 40 CFR 180.l(e): Raw agricultural ccmmodities include among other things
~~ fresh fruits, vfliether or not they have been washed and colored or otherwise
treated in their unpeeled natural form; vegetables in their raw or natural
state, \4iether or not they have been stripped of their outer leaves, waxed,
prepared into fresh green salads, etc.; grains, nuts, eggs, raw milk, meats,
and similiar agricultural produce. It does not include foods that have been
processed, fabricated, or manufactured by cooking, freezing, dehydrating, or
milling.
£/ The Standard Evaluation Procedure (SEP) for Specialty Applications is being
developed concurrently.

Magnitude of the Residue: Post-harvest Fumigation of
Crops and Processed Foods and Feeds
Part II of the Eata Reporting Guideline for Specialty Applications is an
outline/format for a report on a study to determine the magnitude of the
residue which will result on raw crops and processed foods and feeds as a
result of post-harvest fumigation. Other post-harvest treatments are the
subject of Part III of this Data Reporting Guideline. Fumigation may be defined
as the act of releasing and dispersing a toxic chemical so that it reaches
the organism wholly or primarily in the gaseous or vapor state. Both the raw
agricultural conmodities and its processed products may be treated post-harvest
by fumigation.
The report for a study on the post-harvest fumigation of raw crops and
processed foods and feeds should include all information necessary to provide
a oanplete and accurate description of the study. The study should answer the
following question: what is the maximum level of "total toxic residue"^/
that will result in or on the raw food or feed or processed food or feed from the
proposed post-harvest fumigation of the raw or processed cutiaudity with the
pesticide formulated product? Actual residue data on commodities as consumed
should be provided in cases where tolerance level residues lead to unreasonable
risks. Crop group considerations should also be addressed, and an effort
should be made to achieve harmonization with applicable International Residue
Limits (Codex).

Magnitude of the Residue: Post-harvest Treatment
(Except Fumigation) of Crops and Processed Poods and Feeds
Part III of the Cata Reporting Guideline for Specialty Applications is
an outline/format for a report of a study to determine the magnitude of the
residue vihich will result on raw crops and processed foods and feeds as a
result of post-harvest treatments, except fumigation. Post-harvest fumigation
is the subject of Part II of this Eata Reporting Guideline.
Post-harvest treatments of foods and feeds are applied by various means,
including dips, drenches, mechanical foamers, and spray and brush applicators.
The pesticide may be applied directly (to the commodity) or indirectly (to
the storage bin). Often, the application of a wax coating on the comnDdity
is involved. Both the raw agricultural commodity and its processed product
may be treated post-harvest. Additional details on post-harvest treatments
are given in Part III of the Standard Evaluation Procedure for Specialty
Applications .^V
The report for a study on the post-harvest treatment of raw crops and
processed foods and feeds should include all information necessary to provide
a complete and accurate description of the study. The study should answer the
following question: vihat is the maximum level of "total toxic residue" that
will result in or on the raw food or feed or processed food or feed from the
proposed post-harvest treatment of the raw or processed commodity with the
pesticide formulated product? Actual residue data on commodities as consumed
should be provided in cases where tolerance level residues lead to unreasonable
risks. Crop group considerations should also be addressed, and an effort
should be made to achieve harmonization with applicable International Residue
Limits (Codex).
