1 2 3 4

5 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

Requirement is for water environmental chemistry analytical method only; the aquatic field dissipation study is not required. The submission must include results of a successful confirmatory method trial by an independent laboratory. The submission must include a statement of no data confidentiality. Test standards and procedures for independent laboratory validation are available as addenda to the guideline for this requirement. Requirement is for soil environmental chemistry analytical method only; the terrestrial field dissipation study is not required. The submission must include results of a successful confirmatory method trial by an independent laboratory. The submission must include a statement of no data confidentiality. Test standards and procedures for independent laboratory validation are available as addenda to the guideline for this requirement. If any adverse effect is measured in the Tier I study, a Tier II study will be required in order to complete an endangered species assessment. For chlorethoxyfos, the CCA study requires three components: 1) Gestational exposure to pregnant dams followed by sacrifice at gestational day 20. Brain and blood ChE activity is measured in dams and fetuses; 2) Acute, direct dosing to post-nasal day 11 and young adult rats. The acute study is typically accompanied by a range-finding and time to peak effect study; 3) Eleven (11) day repeated, direct, dosing to juvenile rats (PND 11-21) and young adult rats. Each study includes a control group and at least 3 treatment groups. The repeated study is typically accompanied by a range-finding and time to peak effect study. Data is required for the parent compound only. Data are required on hydrolytic degradates that contain the phosphorothioate moeity. Case # and Name: DCI Number: 1 Page: of 1
