This regulation establishes time-limited tolerances for combined residues of emamectin benzoate and its metabolites and photodegradates emamectin benzoate, 4'-epi-methylamino- 4'- deoxyavermectin B<INF>1</INF> benzoate (a mixture of a minimum of 90% 4'-epi-methylamino-4'- deoxyavermectin B<INF>1a</INF> and a maximum of 10% 4'-epi-methlyamino-4'deoxyavermectin B<INF>1b</INF> benzoate) and its metabolites 8,9 isomer of the B<INF>1a</INF> and B<INF>1b</INF> component of the parent insecticide (8,9 ZMA); 4'-deoxy-4'-epi- aminoavermectin B<INF>1</INF> (AB<INF>1a</INF>); 4'deoxy-4'-epi-(N- formyl-N-methyl)amino-avermectin (MFB<INF>1a</INF>); and 4'-deoxy-4'- epi-(N-formyl)amino-avermectin B<INF>1</INF>(FAB<INF>1a</INF>) (CAS No.137512-74-4), in or on cottonseed, cottonseed oil, cotton meal, hulls, and gin trash; and the milk, meat, fat, kidney, and liver of cattle, goats, sheep, and swine. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act authorizing use of the pesticide on cotton. This regulation establishes maximum permissible levels for residues of emamectin benzoate in these food and feed commodities. The tolerances will expire and are revoked on December 31, 2001.
