EPA was also required to reevaluate older, registered pesticides (i.e., "reregistration" for pesticides registered prior to 1984, and more recently, registration review) and to reassess existing tolerances (i.e., tolerance reassessment) to ensure they meet current safety standards. Although U.S. Treasury revenues cover most costs for administering these acts, fees paid by pesticide manufacturers and other registrants have supplemented EPA appropriations for many years as a means of increasing the pace of the agency's activities under FIFRA and FFDCA. The Pesticide Registration Improvement Act (PRIA 1), included in the Consolidated Appropriations Act, 2004 (P.L. 108-199, Title V of Division G), enacted on January 23, 2004, amended FIFRA and modified the framework for collecting fees to enhance and accelerate the agency's pesticide licensing (registration) activities. The amendments included reauthorization ...
