In 1999, EPA proposed to establish procedures primarily directed at implementing provisions of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requiring EPA to issue regulations streamlining its management of the registration process for antimicrobial pesticides, and the main body of the proposal addressed antimicrobial procedures and policies. EPA also proposed to implement a number of general provisions of FIFRA that were not specific to antimicrobial pesticides. In 2001, EPA finalized the provisions not specific to antimicrobial pesticides. This final rule did not promulgate proposed provisions aimed at addressing antimicrobial registration procedures and policies. The implementation of Pesticide Registration Improvement Act (PRIA) addressed registration procedures and policies for all pesticides, including antimicrobial pesticides, and the Agency has determined that a final rule for the remaining provisions in the 1999 proposal is not necessary. Accordingly, EPA intends to withdraw the unfinalized proposed provisions covered by this action in the near future.
