Appendices 25 -2- ------- PESTICIDE ASSESSMENT GUIDELINES RESIDUE CHEMISTRY Specialty Applications Subdivision 0, Series 171-4 DATA REPORTING FOREWORD The Data Reporting Guidelines are addenda to the Pesticide Assessment Guidelines (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 revisions to the Pesticide Assessment Guidelines, nor are they intended for use by Agency reviewers as a mere checklist. While following the Data Reporting Guidelines is not mandatory, data submitters are encouraged to submit complete reports which can be efficiently reviewed by the Agency. The Agency realizes there are sections in the Data Reporting Guidelines which do not apply in all cases. Therefore, registrants should exercise judgment in deciding vhich portions are germane to a specific data submission. This guidance pertains to the substance of the data report. PR Notice 86-5, effective on November 1, 1986 (available from the Registration Support and Emergency Response Branch, Office of Pesticide Programs, US EPA), pertains to the physical formating of reports (which are referred to as "studies") and sutmittal packages. Some of the requirements in PR Notice 86-5 are mandatory. The Data Reporting Guideline on Specialty Applications is divided into three parts: (I) Classification of Seed Treatments and Treatment of Crops Grown for Seed Use Only as Non-Food or Food Uses; (II) Postharvest Fumigation of Crops and Processed Foods and Feeds; (III) Post-harvest Treatment (Except Fumigation) of Crops and Processed Foods and Feeds. Each part gives the format/outline recommended by the Agency to be used by the petitioner/ registrant 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 more thorough clarification of the existing Pesticide Assessment Guidelines. -3- ------- the public notice in the FEEERAL REGISTER of October 15, 1986 (51 FR 36753). The only comment 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. ------- Class! ficatdon of Seed Treatments and Treatment of Crops Grown for Seed Only as Non-Food or Food Uses 1 ^atment of Crops Grown for Seed Use Only the treatment of crops grown for seed use only to be classified as a food use, the following requirements must be met: (1) the seed itself or i js sprouts are not raw agricultural coimrdities ;£/ 2) there is no likelihood c iresidues in crops grown from harvested seed; (3) subsequent to treatment, a JL parts of the crop are not fit for human or animal consumption. Details of t bse requirements and any exceptions are given in Part I of the Standard E aluation Procedure for Specialty Applications .£/ If the treatment of the c bp grown for seed use only is classified as a non-food use, no residue s jidies are needed. If the treatment of the crop grown for seed use only is c assified as a food use, metabolism and crop field studies are needed. The f tmats for the metabolism and crop field studies^/ are addressed in separate E La Reporting Guideline documents being developed concurrently, and the r ijistrant/petitioner is referred to those Data Reporting Guidelines when the t satment of crops grown for seed use only is classified as a food use. S ad Treatments i | For seed treatments to be classified as a non-food use, data fron a r aiotracer study are needed demonstrating no uptake of radioactivity to the a rial portion and edible root (both human and livestock consumption) portion c I the crop.£/ If the radiotracer study dertDnstrates that the particular seed t patment is a non-food use, no further studies are needed. If the seed t patment is classified as a food use, plant metabolism and crop field studies^/ a a needed, and the registrant is referred to the Data Reporting Guidelines f r those studies. 40 CFR 180.l(e): Raw agricultural commodities include among other things fresh fruits, whether or not they have been washed and colored or otherwise i treated in their unpeeled natural form; vegetables in their raw or natural i state, whether 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. 2/ The Standard Evaluation Procedure (SEP) for Specialty Applications is being developed concurrently. £/ See Data Reporting Guideline for Magnitude of the Residue: Crop Field Trials; and Data Reporting Guideline for Nature of the Residue; Plants, available from the National Technical Information Service (NTIS), PB86-248192 and PB87-208641 respectively. 5/ For additional details, see Part I of the SEP for Specialty Applications. -5- ------- The guideline given below in Part I of the Data Reporting Guideline for Specialty Applications is a format/outline for the radiotracer study determining whether or not the seed treatment results in uptake of radioactivity to the aerial edible and root portions of the crop. The report for this study . should include all information necessary to provide a complete and accurate description of the study.

Other post-harvest treatments are the subject of Part III of this Eata 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 ccmmodities 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 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 fumigation of the raw or processed canmodity with the pesticide formulated product? Actual residue data on commodities as consumed should be provided in oases 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).
