This rule revises tolerances for residues of the insecticide chlorpyrifos in or on the raw agricultural commodities peaches, pears, plums, and nectarines by establishing the current time-limited tolerances as permanent tolerances. The regulations to establish maximum permissible levels of residues of the insecticide were requested in petitions submitted by DowElanco and are needed to cover maximum expected residues in or on imported commodities.
