This regulation establishes a time-limited tolerance for residues of Halosulfuron-methyl in or on asparagus. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on asparagus. This regulation establishes a maximum permissible level for residues of halosulfuron- methyl in this food commodity. The tolerance will expire and is revoked on December 31, 2003.
