The freshwater fish test species for the TEP testing is the most sensitive of the species tested with the TGAI. Freshwater invertebrate and acute estuarine and marine organisms must also be tested with the EP or TEP using the same species tested with the TGAI. Required if a terrestrial species exhibits a 25 percent or greater detrimental effect in Tier 1 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. 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. In July 2009, revisions were made to harmonizad guideline numbers and associated footnotes in 40 CFR. These revisions are not reflected in the data call-in (see 40 CFR parts 158). Generally not required for granular formulations. May be requested on a case-by-case basis. For greenhouse 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 or to support end use products when there is no registered manufacturing-use product. Avian acute oral data are not required for liquid formulations for greenhouse and indoor uses. the study is not required 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 or to support these same end-use products when there is no registered manufacturing use product. For greenhouse 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 or to support end-use products when there is no registered manufacturing-use product. 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 (EEC) 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. 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 (EEC) 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, but not limited to 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 using the TGAI are required to support all outdoor end-use product uses including, but not limited to turf.

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 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. Data are required on one estuarine/marine mollusk, one estuarine/marine invertebrate and one estuarine/marine fish species. Data are required on one estuarine/marine molluck, one estuarine/marine invertebrate and one estuarine/marine fish species. Data are required on one coldwater fish and one warmwater fish for terrestrial, aquatic, forestry, and residential outdoor uses. For indoor and greenhouse uses, testing with only one of either fish species is required. Data are preferred on waterfowl and upland game bird species. 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. Conduct with TGAI An acute oral study testing a passerine species is required. Case # and Name: DCI Number: 2 Page: of 2
