II. Background

    EPA is conducting its registration review of 4-CPA pursuant to the 
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) section 
3(g) (7 U.S.C. 136a(g)) and the Procedural Regulations for Registration 
Review at 40 CFR part 155, subpart C. FIFRA section 3(g) provides, 
among other things, that pesticide registrations are to be reviewed 
every 15 years. Consistent with 40 CFR 155.57, in its final 
registration review decision, EPA will ultimately determine whether a 
pesticide continues to meet the registration standard in FIFRA section 
3(c)(5) (7 U.S.C. 136a(c)(5)). As part of the registration review 
process, the

proposed decision and invited the public to submit any comments or new 
information, consistent with 40 CFR 155.58(a). EPA considered and 
responded to any comments or information received during the public 
comment period in the final registration review decision.
