The ILV for fluroxypyr-MHE must include both the degradate fluroxypyr acid and the MHE. -As referenced in the problem formulation as well as in the EFED response to comments, studies should be conducted for: 1. Environmental Chemistry Analytical Method for Soil and Associated Independent Laboratory Validation, 2. Environmental Chemistry Analytical Method in Water and Associated Laboratory Validation. Test is for MHE only. Study is for both fluroxypyr-MHE and the degradate fluroxypyr acid. Measurements of residues in the pollen/nectar are needed based upon lower-tiered tests and/or other lines of evidence, and the need for a refined pollinator risk assessment. A study protocol must be submitted to, and reviewed by EPA, prior to study initiation. The following elements should be considered when developing study protocol(s) for the monitoring of residues in pollen/nectar. Consideration of the range of application methods and environmental conditions (e.g., soil and hydric regimes) that the target crop(s) may be under. Consideration of the attractiveness of the selected crop to pollinators 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. 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. Consideration of the market proportion of the selected target crop(s). Compost must be derived from clippings of turf grass treated with fluroxypyr-MHE. Fluroxypyr must be applied to the turf as a TEP, with typical application methods at the maximum application rate of 0.72 lb a.i/A. The composting methods should represent typical use methods for commercial or municipal processing of grass-based compost. The study should measure the concentration of fluroxypyr-MHE, fluroxypyr acid and major degradation products over time and establish dissipation half-lives for fluroxypyr-MHE and fluroxypyr acid. Additional data are needed to address deficiencies of the previously submitted study. See the EPA document Problem Formulation and the Drinking Water Exposure Assessment for ecological risks and details of these deficiencies. A study protocol must be submitted to, and reviewed by EPA prior to study initiation. A protocol must be submitted and approved by the Agency prior to the study.

The ILV for fluroxypyr-MHE must include both the degradate fluroxypyr acid and the MHE. -As referenced in the problem formulation as well as in the EFED response to comments, studies should be conducted for: 1. Environmental Chemistry Analytical Method for Soil and Associated Independent Laboratory Validation, 2. Environmental Chemistry Analytical Method in Water and Associated Laboratory Validation. Test is for MHE only. Study is for both fluroxypyr-MHE and the degradate fluroxypyr acid. Measurements of residues in the pollen/nectar are needed based upon lower-tiered tests and/or other lines of evidence, and the need for a refined pollinator risk assessment. A study protocol must be submitted to, and reviewed by EPA, prior to study initiation. The following elements should be considered when developing study protocol(s) for the monitoring of residues in pollen/nectar. Consideration of the range of application methods and environmental conditions (e.g., soil and hydric regimes) that the target crop(s) may be under. Consideration of the attractiveness of the selected crop to pollinators 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. 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. Consideration of the market proportion of the selected target crop(s). Compost must be derived from clippings of turf grass treated with fluroxypyr-MHE. Fluroxypyr must be applied to the turf as a TEP, with typical application methods at the maximum application rate of 0.72 lb a.i/A. The composting methods should represent typical use methods for commercial or municipal processing of grass-based compost. The study should measure the concentration of fluroxypyr-MHE, fluroxypyr acid and major degradation products over time and establish dissipation half-lives for fluroxypyr-MHE and fluroxypyr acid. Additional data are needed to address deficiencies of the previously submitted study. See the EPA document Problem Formulation and the Drinking Water Exposure Assessment for ecological risks and details of these deficiencies. A study protocol must be submitted to, and reviewed by EPA prior to study initiation. A protocol must be submitted and approved by the Agency prior to the study.
