This regulation extends time-limited tolerances for residues of the herbicide desmedipham in or on red beet roots at 0.2 part per million (ppm) and red beet tops at 15 ppm for an additional 16-month period. These tolerances will expire and are revoked on December 31, 2000. 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 garden (red) beets. Section 408(l)(6) of the Federal Food, Drug, and Cosmetic Act requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under FIFRA section 18.
