\1\ EPA did not establish a docket for this case because all products were voluntarily canceled by the
registrants, before the registration review assessments were initiated.
II. Background
EPA is conducting its registration review of the chemicals listed
in Table 1 of Unit I 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 Agency has completed
case closures for the pesticides in Table 1 of Unit I because all
products in the cases are cancelled.
For additional background on the registration review program, see:
