EPA’s Preliminary Regulatory Determinations for Contaminants on the Fourth Drinking Water Contaminant Candidate List
On March 10, 2020, EPA published its preliminary regulatory determinations for eight contaminants listed on its fourth Contaminant Candidate List under the Safe Drinking Water Act. The agency presented its preliminary determinations to regulate two contaminants: perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). EPA also provided a preliminary determination to not regulate six contaminants: 1,1-dichloroethane, acetochlor, methyl bromide, metolachlor, nitrobenzene, and Royal Demolition explosive. A regulatory determination is a decision about whether or not to begin the process to propose and promulgate a national primary drinking water regulation for an unregulated contaminant. EPA also included updates on three other contaminants: strontium, 1,4-dioxane, and 1,2,3-trichloropropane.
Comments are now due on June 10, 2020. Extended from the original date of May 11, 2020.
