  1. (a)General.
    1. (1)Tolerances are established for residues of the herbicide, pyraflufen-ethyl, including its metabolites and degradates, in or on the plant commodities listed in table 1 to this paragraph (a)(1). Compliance with the plant commodity tolerance levels specified in table 1 to this paragraph (a)(1) is to be determined by measuring only the sum of the parent pyraflufen-ethyl, ethyl 2-[2-chloro-5-(4-chloro-5-difluoromethoxy)-1-methyl-1H-pyrazol-3-yl]-4-fluorophenoxy] acetate, and its acid metabolite, E-1, 2-chloro-5-(4-chloro-5-difluoromethoxy-1-methyl-1H-pyrazol-3-yl)-4-fluorophenoxyacetic acid, calculated as the stoichiometric equivalent of pyraflufen-ethyl in or on the commodity.
    2. (2)Tolerances are established for residues of the herbicide, pyraflufen-ethyl, including its metabolites and degradates, in or on the livestock commodities in table 2 to this paragraph (a)(2). Compliance with the livestock commodity tolerance levels specified in table 2 to this paragraph (a)(2) is to be determined by measuring only the sum of the parent pyraflufen-ethyl, ethyl 2-[2-chloro-5-(4-chloro-5-difluoromethoxy)-1-methyl-1H-pyrazol-3-yl]-4-fluorophenoxy] acetate and its acid metabolites: E-1, 2-chloro-5-(4-chloro-5-difluoromethoxy-1-methyl-1H-pyrazol-3-yl)-4-fluorophenoxyacetic acid, and E-9, 2-chloro-5-(4-chloro-5-difluoromethoxy-1H-pyrazol-3-yl)-4-fluorophenoxyacetic acid, both calculated as the stoichiometric equivalent of pyraflufen-ethyl in or on the commodity.

  3. (c)Tolerances with regional registrations. [Reserved]
  4. (d)Indirect or inadvertent residues. [Reserved]
