This regulation establishes time-limited tolerances for residues of chlorantraniliprole in or on various sweet corn commodities and in milk. This action is in response to EPA's granting of emergency exemptions under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on sweet corn. This regulation establishes maximum permissible levels for residues of chlorantraniliprole in or on these food commodities. The time-limited tolerances expire and are revoked on December 31, 2011.
