The results of the Activated Sludge, Respiration Inhibition Test (ASRI), GLN 850.3300, will determine which of the four biodegredation tests is/are required. If the ASRI test results in an EC50 of less than or equal to 20 mg/L, then the registrant is required to conduct either the (i) Simulation tests to assess the biodegradability of chemicals discharged in wastewater1, GLN 835.3280, (ii) the Simulation Test Aerobic Sewage Treatment A. Activated Sludge Units, GLN 835.3240, or (iii) the Porous Pot Test, GLN 835.3220. If the ASRI test results in an EC50 greater than 20 mg/L, then the registrant would be required to conduct either the (i) Ready Biodegradability, GLN 3110, (ii) Simulation tests to assess the biodegradability of chemicals discharged in wastewater, (iii) the Simulation Test Aerobic Sewage Treatment A. Activated Sludge Units, or (iv) the Porous Pot Test. If the Ready Biodegradability Study is conducted and passes, then no further testing is required. If, however, the pesticide fails the Ready Biodegradability study, then the registrant is required to conduct either the (i) Simulation tests to assess the biodegradability of chemicals discharged in wastewater, (ii) the Simulation Test Aerobic Sewage Treatment A. Activated Sludge Units, or (iii) the Porous Pot Test. The need for measures of residues in pollen/nectar will be determined based upon lower tiered tests and/or other lines of evidence, and the need for a refined pollinator risk assessment. The need for a semi-field test for pollinators (i.e., either a field-feeding test or a tunnel test) will be determined based upon the results of lower-tiered tests and/or other lines of evidence, and the need for a refined pollinator risk assessment. The need for a field test for pollinators will be determined based upon lower-tiered tests and/or other lines of data and the need for a refined pollinator risk assessment. The following elements should be considered when developing study protocol(s) for the monitoring of residues in pollen/nectar. (1) Consideration of the range of application methods and environmental conditions (e.g., soil and hydric regimes) that the target crop(s) may be under. (2) Consideration of the attractiveness of the selected crop to pollinators (3) Consideration of a collection schedule sufficient to allow for an understanding of the character of residues, in the pollen/nectar and/or plant tissues, over time. (4) Consideration of data sufficient to determine whether residues of the active ingredient and/or degradation product(s) accumulates in soil and is/are bioavailable for plant to uptake in a following planting, and therefore result in potential exposure to pollinators. (5) Consideration of the market proportion of the selected target crop(s).See the OECD 213: OECD Guidelines for the Testing of Chemicals.

Residue dissipation studies are required for textiles (clothing) and the plush of carpets. If specified on the label that only carpet backing is treated, then a residue study will not be needed for carpets. Required only from registrants with registrations for antimicrobial use. OECD has not yet finalized test guidelines for chronic studies, and efforts are underway to develop standardized guidelines for assessing the effects from chronic exposure to adult and larvae in the laboratory. Discussion of the study design elements for the 10-day adult toxicity test can be found in Appendix O of the European Food Safety Authority (EFSA) guidance document: EFSA. Guidance on the risk assessment of plant protection products on bees (Apis mellifera, Bombus spp. and solitary bees. EFSA Journal 2013;11(7):3295, 266 pp. doi:10.2903/j.efsa.2013.3295. Available online at: http://www.efsa.europa.eu/en/efsajournal/doc/3295.pdf OECD has not yet finalized test guidelines for chronic studies with honey bee larvae. OECD draft guidance is being developed, see OECD Draft Guidance Document Honey Bee (Apis mellifera) Larval Toxicity Test, Repeated Exposure, http://www.oecd.org/env/ehs/testing/Draft_GD_honeybees_rep_exp_for_2nd_CR_25_November_2013.pdf OECD Test Guideline 237 may be used to develop a protocol for this study (OECD. 2013 Guidelines for Testing Chemicals. Honey bee (Apis mellifera) larval toxicity test, single exposure.) See: http://www.oecd-ilibrary.org/environment/test-no-237-honey-bee-apis-mellifera-larval-toxicity-test-single-exposure_9789264203723-en. In some cases, information pertaining to acute toxicity to honey bee larvae may be obtained with the chronic honey bee larvae test thereby negating the need for separate acute and chronic larval toxicity tests. Formal guidelines for semi-field tests do not yet exist; however, information that can help guide the development of either a semi-field tunnel test protocol can be found at OECD 75, see: OECD. 2007. Series on Testing and Assessment Number 75. Guidance document on the honey bee (Apis mellifera L.) brood test under semi-field conditions. Environmental Directorate Joint Meeting of the Chemicals Committee and the Working Party on Chemicals, Pesticides and Biotechnology. ENV/JM/MONO(2007)22. August 31, 2007. http://www.oecd.org/officialdocuments/publicdisplaydocumentpdf/?cote=env/jm/mono(2007)22&doclanguage=en. For products with both indoor and outdoor uses, and similar conditions of use, data are generally required for the indoor applications only. However, data for outdoor uses are required if the Agency expects outdoor uses to result in greater exposure than indoor uses (e.g., higher use rates and application, frequency, or longer exposure duration, or application methods/equipment) create potential for increased dermal or inhalation exposure in outdoor versus indoor use sites). In certain cases, when a pesticide may be used both indoors and outdoors under dissimilar conditions of use, the Agency may require submission of applicator exposure data for both use patterns. For field-feeding studies see the following: Oomen et al. 1992: Oomen, P. A. A. DeRuijter and J. Van der Steen. 1992. Method for honey bee brood feeding tests with insect growth-regulating insecticides. Bul OEPP/EPPO Bulletin 22: 613-616. Environmental chemistry analytical methods and associated laboratory validations for water only. EPA has a published final guideline for this study: http://www.regulations.gov/#!documentDetail;D=EPA-HQ-OPPT-2009-0152. The required biodegradation study is based on the results of an Activated Sludge Respiration Inhibition test. Airless sprayer and brush/roller. A study protocol must be submitted to, and reviewed by EPA, prior to study initiation. Case # and Name: DCI Number: 2 Page: of 2
