This final rule will reduce burden to restricted use pesticide applicators and simplify federal certification expiration dates. Restricted use pesticides (RUPs) are those which may generally cause unreasonable adverse effects on the environment without additional restrictions. RUPs may only be applied by or under the direct supervision of an applicator certified as competent by a certifying agency. A State, tribe, or Federal agency becomes a certifying agency by receiving approval from EPA on their certification plan. In areas not covered by a certifying agency, EPA may establish a Federal certification plan and issue Federal certificates directly. One way EPA may issue a Federal certificate is based on an existing valid certificate from a certifying agency, and this final rule will synchronize the expiration dates on the Federal certificate with that of the certifying agency certificate on which the Federal certificate is based.
