Data on other end use products will be required on a case-by-case basis. For pesticides in the production stage, a rudimentary product analytical method and data will suffice to support an experimental use permit.(iv) Routinely required for products produced by an integrated formulation system. Required on a case-by-case basis for other products or materials.

The following notes are referenced in column two of the table contained in paragraph (b)(1) of this section.(i) Residue chemistry data requirements shall apply to biochemical pesticide products when any one or more of the following conditions apply:(A) Tier II or III toxicology data are required, as specified for biochemical agents in (c)(1) of this section.(B) The application rate of the product exceeds 0.7 ounces (20 grams) active ingredient per acre per application.(C) The application rate of the product exceeds a level determined to be comparable to 0.7 ounces active ingredient per application but the application rate is not expressable in terms of ounces per acre per application.(ii) The same chemical identity data as required in (a)(1) of this section are required, with emphasis on impurities that could constitute a residue problem.(iii) Required information includes crops to be treated, rate of application, number and timing of applications, preharvest intervals, and relevant restrictions.(iv) Data on metabolism in livestock are required when residues occur on a livestock feed, or the pesticide is to be applied directly to livestock.(v) A residue method suitable for enforcement of tolerances is needed whenever a numeric tolerance is proposed Exemptions from the requirement of a tolerance will also usually require an analytical method.(vi) Data on the nature and level of residue in processed food/feed are required when detectable residues could concentrate on processing and thus require establishment of a food additive tolerance.(vii) Livestock feeding studies are required whenever a pesticide occurs as a residue in any livestock feed. Direct application to livestock uses will require animal treatment residue studies.(viii) Data on residues in potable water are required whenever a pesticide is to be applied directly to water, unless it can be determined that the treated water would not be used (eventually) for drinking purpose, by man or animals.(ix) Data on residues in fish are required whenever a pesticide is to be applied directly to water.(x) Data on residues in irrigated crops are required when a pesticide is to be applied directly to water that could be used for irrigation or to irrigation facilities such as irrigation ditches.(xi) Data or residues in food/feed in food handling establishments are required whenever a pesticide is to be used in food/feed handling establishments.(xii) Reduction of residue data are required when the assumption of tolerance level residues results in an unsafe level of exposure. Data on the level of residue in food as consumed will be used to obtain a more precise estimate of potential dietary exposure.(xiii) The proposed tolerance must reflect the maximum residue likely to occur in crops and meat/milk/poultry/eggs.(xiv) Residue data for outdoor domestic uses are required if home gardens are to be treated and the home garden use pattern is different from the use pattern on which the tolerances were established.
