ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 141
Announcement of Preliminary Regulatory Determinations for Contaminants on the Third Drinking Water Contaminant Candidate List
AGENCY: Environmental Protection Agency (EPA).
ACTION: Request for public comment.
SUMMARY: The Safe Drinking Water Act (SDWA), as amended in 1996, requires the Environmental Protection Agency (EPA) to make regulatory determinations every five years on at least five unregulated contaminants. A regulatory determination is a decision about whether or not to begin the process to propose and promulgate a national primary drinking water regulation (NPDWR) for an unregulated contaminant. These unregulated contaminants are chosen from the Contaminant Candidate List (CCL), which SDWA requires the agency to publish every five years. EPA published the third CCL (CCL 3) in the Federal Register on October 8, 2009. This notice presents the preliminary regulatory determinations and supporting rationale for 5 of the 116 contaminants listed on CCL 3. The agency is making preliminary determinations to regulate one contaminant (i.e., strontium) and to not regulate four contaminants (i.e., 1,3-dinitrobenzene, dimethoate, terbufos and terbufos sulfone). EPA seeks comment on these preliminary determinations.
DATES: Comments must be received on or before December 19, 2014, 60 days after publication in the Federal Register.
