1. (a)General.
   1. (1)Tolerances are established for residues of the insecticide dicofol, including its metabolites and degradates, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only dicofol as the sum of its p,p-dicofol and o,p-dicofol isomers: 4-chloro-α-(4-chlorophenyl)-α-(trichloromethyl)benzenemethanol and 2-chloro-α-(4-chlorophenyl)-α-(trichloromethyl)benzenemethanol, in or on the commodity.
   2. (2)Tolerances are established for residues of the insecticide dicofol, including its metabolites and degradates, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of p,p-dicofol, 4-chloro-α-(4-chlorophenyl)-α-(trichloromethyl)benzenemethanol, its isomer o,p-dicofol, 2-chloro-α-(4-chlorophenyl)-α-(trichloromethyl)benzenemethanol, and its metabolites 4-chloro-α-(4-chlorophenyl)-α-(dichloromethyl)benzenemethanol and 2-chloro-α-(4-chlorophenyl)-α-(dichloromethyl)benzenemethanol, calculated as the stoichiometric equivalent of p,p-dicofol, 4-chloro-α-(4-chlorophenyl)-α-(trichloromethyl)benzenemethanol, in or on the commodity.
2. (b)Section 18 emergency exemptions. [Reserved]
3. (c)Tolerances with regional registrations. [Reserved]
4. (d)Indirect or inadvertent residues. [Reserved]
