13 Key: Residue of Concern = Residue of Concern; TEP = Typical End Use Product [TEP]; TGAI = Technical Grade Active Ingredient [TGAI]; TGAI/PAIRA = Technical Grade of the Active Ingredient or Pure Active Ingredient, Radio Labelled; TGAI, TEP = Technical Grade of the Active Ingredient or Technical End-Use Product; TGAI/PAI = Technical Grade Active Ingredient, Pure Active Ingredient

This requirement is required for acephate AND its degradate methamidophos. This guideline is required for acephate (parent compound) AND its degredate, methamidophos. TGAI, RAI, Degr TGAI & Degr Requirement for terrestrial uses is based on potential for aquatic exposure and if pesticide residues have the potential for persistence, mobility, nontarget aquatic toxicity or bioaccumulation. Not required for aquatic residential uses. Required if the tested aquatic species exhibits a 50 percent or greater detrimental effect in the Tier I study. When Tier II testing is required, the test species should be the species that showed detrimental effects in the tier I testing. Required for known phytotoxicants such as herbicides, desiccants and defoliants. Required for aquatic food and nonfood crop uses for aquatic sites that are intermittently dry. Such sites include, but are not limited to cranberry bogs and rice paddies. Not required when the chemical is to be applied only by soil injection or is incorporated in the soil. Not required for contained pesticide treatments such as bait boxes and pheromone traps unless adverse effects reports are received by the Agency. Not required for aquatic residential uses.For greenhouse and indoor end-use products, data using the TGAI arerequired to support manufacturing-use products to be reformulated into these same end-use products or to support enduse products when there is noregistered manufacturing use product. Avian acute oral data are not requiredfor liquid formulations for greenhouse and indoor uses. The study is notrequired if there is no potential for environmental exposure. For greenhouse and indoor end-use products, data using the TGAI are required to support manufacturing-use products to be reformulated into these Case # and Name: DCI Number: 1 Page: of

same end-use products or to support end-use products when there is no registered manufacturing use product. For greenhous and indoor end-use products, data using the TGAI are required to support manufacturing-use products to be reformulated into these same end use products when there is no registered manufacturing-use product. 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 using the TGAI are required to support all outdoor end-use product uses including turf. Data are generally not required to support end use products in the form of a gas, a highly volatile liquid, a highly reactive solid, or a highly corrosive material. Data are required on one passerine species. Data are required on Pseudokirchneriella subcapitata, Selenastrum capricorntum, Skeletonema costatum, Navicula pilliculosa. Conduct with TGAI or PAI, & Degr 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.
