3 4

5 6 7 8 9 10 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

The freshwater fish test species for the TEP testing is the most sensitive of the species tested with the TGAI. Freshwater invertebrate and acute estaurine and marine organisms must also be tested with the EP or TEP using the same species tested with the TGAI. EP or TEP testing is required for any product which meets any of the following conditions: (i) the end use pesticide will be introduced directly into an aquatic environment (e.g. aquatic herbicides and mosquito larvicides) when used as directed, (ii) the maximum expected environmental concentration (MEEC) or the estimated environmental concentration (EE) in the aquatic environment is greater than or equal to one-half the LC50 or EC50 of the TGAI when the EP is used as directed, (iii) an ingredient in the end-use formulation other than the active ingredient is expected to enhance the toxicity of the active ingredient or to cause toxicity to aquatic organisms. 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 estuarine/marine species if the product is: (i) intended for direct application to the estuarine or marine environment; (ii) expected to enter this environment in significant concentrations because of its expected use or mobility patterns, and (iii) if the acute LC50 or EC50 < 1 mg/l; or (iv) if the estimated environmental concentration in water is equal to or greater than 0.01 of the acute EC50 or LC50 and any of the following conditions exist: (a) studies of other organisms indicate the reproductive physiology of fish and/or invertebrates may be affected; (b) physicochemical properties indicate bioaccumulation of the pesticide; (c) the pesticide is persistent in water (e.g., half-life in water greater than 4 days). Data are preferred on oppossum shrimp (America mysis) formerly (Mysidopsis bahia). Data are preferred on eastern oyster (Crassostrea virginica) and oppossum shrimp (America mysis) formerly (Mysidopsis bahia) and silver side (Menidia sp.) Data are generally not required for outdoor residential uses, other than turf, unless the data indicate that pesticide residues from the proposed use(s) can potentially enter waterways. Data are generally not required for outdoor residential uses, other than turf, unless data indicate that pesticide residues from the proposed use(s) can potentially enter waterways. 850.1350 aquatic invertebrate life cycle (saltwater) - data are required on one estaurine/marine invertebrate species. 850.1035 acute toxicity estaurine and marine organisms - data are required on one estuarine/marine mollusk, one estaurine/marine invertebrate, and one estaurine/marine fish species.
