5. Description of content:   The U.S. Environmental Protection Agency (EPA) is proposing
the revocation of tolerances for the herbicides:
4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one[Metribuzin],
dichlobenil, pendimethalin, and terbacil; and the insecticide O-ethylO-
[4-(methylthio)phenyl] S-propyl phosphorodithioate [Sulprofos].  EPA expects to determine
whether any individuals or groups want to support these tolerances.  Also, this document is
proposing the establishment and revision of tolerances for 4-amino-6-(1,1-dimethylethyl)-3-
(methylthio)-1,2,4-triazin-5(4H)-one (metribuzin), dichlobenil, pendimethalin, terbacil, andthe plant growth regulator diphenylamine.  In addition EPA is also proposing to revise
commodity terminology for 4-amino-6-(1,1-dimethylethyl)3-(methylthio)-1,2,4-trizin –
5(4H)-one [Metribuzin], diphenylamine, and pendimethalin to conform to current practice.
