(a) General. (1) Tolerances are established for residues of the herbicide triclopyr, including its metabolites and degradates, in or on the commodities in table 1 to this paragraph (a)(1) resulting from the application of the butoxyethyl ester of triclopyr, triethylamine salt of triclopyr, or choline salt of triclopyr. Compliance with the tolerance levels specified in table 1 to this paragraph (a)(1) is to be determined by measuring only triclopyr, 2-[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid in or on the commodity.

(2) Tolerances are established for residues of the herbicide triclopyr, including its metabolites and degradates, in or on the commodities in table 2 to this paragraph (a)(2) resulting from the application of the butoxyethyl ester of triclopyr, triethylamine salt of triclopyr, or choline salt of triclopyr. Compliance with the tolerance levels specified in table 2 to this paragraph (a)(2) is to be determined by measuring the combined residues of triclopyr, 2-[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid, and its metabolite 3,5,6-trichloro-2-pyridinol (TCP), calculated as the stoichiometric equivalent of triclopyr in or on the commodity.

(3) Tolerances are established for residues of the herbicide triclopyr, including its metabolites and degradates, in or on the commodities in table 3 to this paragraph (a)(3) resulting from the application of the butoxyethyl ester of triclopyr, triethylamine salt of triclopyr, or choline salt of triclopyr. Compliance with the tolerance levels specified in table 3 to this paragraph (a)(3) is to be determined by measuring the combined residues of triclopyr (2-[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid) and its metabolites 3,5,6-trichloro-2-pyridinol (TCP) and 2-methoxy-3,5,6-trichloropyridine (TMP), calculated as the stoichiometric equivalent of triclopyr in or on the commodity.

(b) Section 18 emergency exemptions. Time-limited tolerances specified in the following table are established for residues of the triclopyr (2-[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid), including its metabolites and degradates in or on the specified agricultural commodities, resulting from use of the pesticide pursuant to FIFRA section 18 emergency exemptions. The tolerances expire on the date specified in the table.
