This regulation establishes a time-limited tolerance for residues of clothianidin in or on rice, grain. This action is in response to EPA's granting of an emergency exemption under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of thiamethoxam on rice. Emergency use of thiamethoxam on rice results in potential clothianidin (a major metabolite of thiamethoxam) residues that when combined with the residues from legal use of clothianidin on rice, require an increase in the tolerance for residues of clothianidin in rice. Although there is an existing regulation establishing a maximum permissible level for residues of clothianidin in or on rice, grain at 0.01 ppm, this rule would establish a new, time-limited maximum permissible level at 0.5 ppm for clothianidin in or on rice, grain. The time-limited tolerance expires on December 31, 2024. This action is also associated with the utilization of a crisis exemption under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of thiamethoxam on rice.
