(a) General.
(1) Tolerances are established for the residues of the herbicide dicamba (3,6-dichloro-o-anisic acid), including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels is to be determined by measuring only the sum of the residues of dicamba (3,6-dichloro-o-anisic acid) and its metabolite, 3,6-dichloro-5-hydroxy-o-anisic acid, calculated as the stoichiometric equivalent of dicamba, in or on the following commodities:

(2) Tolerances are established for residues of the herbicide dicamba, 3,6-dichloro-o-anisic acid, including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels is to be determined by measuring only the residues of dicamba (3,6-dichloro-o-anisic acid) and its metabolite, 3,6-dichloro-2-hydroxybenzoic acid, calculated as the stoichiometric equivalent of dicamba, in or on the following commodities:
| Commodity | Parts per million |

| Cattle, fat | 0.3 |
| Cattle, kidney | 25.0 |
| Cattle, meat | 0.25 |
| Cattle, meat byproducts, except kidney | 3.0 |
| Goat, fat | 0.3 |
| Goat, kidney | 25.0 |
| Goat, meat | 0.25 |
| Goat, meat byproducts, except kidney | 3.0 |
| Hog, fat | 0.3 |
| Hog, kidney | 25.0 |
| Hog, meat | 0.25 |
| Hog, meat byproducts, except kidney | 3.0 |
| Horse, fat | 0.3 |
| Horse, kidney | 25.0 |
| Horse, meat | 0.25 |
| Horse, meat byproducts, except kidney | 3.0 |
| Milk | 0.2 |
| Sheep, fat | 0.3 |
| Sheep, kidney | 25.0 |
| Sheep, meat | 0.25 |
| Sheep, meat byproducts, except kidney | 3.0 |
(3) Tolerances are established for residues of the herbicide dicamba, 3,6-dichloro-o-anisic acid, including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels is to be determined by measuring only the residues of dicamba, 3,6-dichloro-o-anisic acid, and its metabolites, 3,6-dichloro-5-hydroxy-o-anisic acid, and 3,6-dichloro-2-hydroxybenzoic acid, calculated as the stoichiometric equivalent of dicamba, in or on the following commodities:
| Commodity | Parts per million |
|---|---|
| Cotton, gin byproducts | 70 |
