Federal Register Notice-Preliminary Regulatory Determinations
Today, a notice appeared in the Federal Register announcing EPA’s preliminary regulatory determinations.
The Agency is making preliminary determinations to regulate two contaminants (i.e., PFOS and PFOA) and to not regulate six
contaminants (i.e., 1,1-dichloroethane, acetochlor, methyl bromide, metolachlor, nitrobenzene, and RDX).
A preliminary regulatory determination lays out and takes comment on EPA’s view about whether certain unregulated contaminants meet
three statutory criteria. After EPA considers public comment, EPA makes a final determination.
The EPA seeks comment on these preliminary determinations. The EPA is also presenting an update on three other
CCL 4 contaminants (strontium, 1,4-dioxane, and 1,2,3-trichloropropane).
Comments must be received on or before May 11, 2020.
