This study must assess both acute and subchronic parameters to evaluate the potential of a repeated chemical exposure to produce adverse effects on the nervous system. The timeframe for completing the acute neurotoxicty screening study is 12 months. The registrant must revise the existing method to include an enzymatic and/or mild acid hydrolysis step to release conjugated residues of this chemical. Studies using single serving samples of a raw agricultural commodity may be needed for acutely toxic pesticides and/or their metabolites. These residue studies must be conducted using a statistical design accepted by the Agency. Required if indoor use could result in pesticide residues in or on food or feed. Required for residential outdoor use on food crops if home gardens are to be treated or the home garden use is different from the agricultural use pattern on which the tolerance is established. Required for indoor uses which are direct postharvest treatments of raw agricultural commodities (e.g., fungicidal waxes or stored grain fumigants). New analytical methods to be used for enforcement puposes must include results from an independent laboratory validation. For a national registration, the draft guidance document recommends that a total of 8 field trials be performed on representative varieties (specifically, 3 trials in EPA Growing Zone 12, 2 trials in Zone 11, and 3 trials in Zone 5). For a regional Pacific Northwest registration (growing regions 11 and 12), the draft guidance document recommends that a total of 5 field trials be performed on representative varieties (specifically, 3 trials in EPA Growing Zone 12 and 2 trials in Zone 11). Environmental chemistry used to generate data associated with this study must include results of a successful confirmatory method trial by an independent laboratory. Test standards and procedures for independent laboratory validation are available as addenda to the guideline for this test requirement. Environmental chemistry methods used to generate data associated with this study must include results of a successful confirmatory method trial by an independent laboratory. The environmental chemistry methods must include a statement of no data confidentiality claims, i.e., non-CBI. Test standards and procedures for independent laboratory validation are available as addenda to the guideline for this test requirement. Data on residue analytical methods arre required for both plants and livestock commodities. Data are required on one passerine species and either one waterfowl species or one upland game bird species for terrestrial, aquatic, forestry, and residential outdoor uses. Data are preferred on waterfowl or upland game bird species for indoor and greenhouse uses. Additional measurements such as cholinesterase activity for certain pesticides, e.g., organophosphates and some carbamates, will also be required. The route of exposure must correspond with the primary route of exposure. A residue method, storage stability data, and crop field trials are required for the nonfood crop tobacco (green, freshly harvested). Depending on the level of residues found on the green tobacco, additional data may be required on cured/dried tobacco and pyrolysis products (guideline 860.1000).

A passerine study protocol must be submitted for review by the Agency prior to initiation of this study. New analytical methods to be used for enforcement purposes must include results from an independent laboratory validation. Data using the TEP are conditionally required based on the results of the avian acute oral (TGAI) and avian subacute dietary tests, intended use pattern, and pertinent environmental fate characteristics that indicate potential exposure. A residue analytical method suitable for enforcement purposes is required whenever a numeric tolerance (including temporary and time-limited tolerance) is proposed, and may be required for a tolerance exemption.
