OMB Receives EPA’s Proposed CCL 4

On Saturday the OMB’s Office of Information and Regulatory Affairs (OIRA) announced that it had received a copy of the Environmental Protection Agency’s  (EPA) new proposed Drinking Water Contaminant Candidate List (CCL 4). According to the EPA’s CCL web page:

“EPA must periodically publish this list of contaminants (called the Contaminant Candidate List or CCL) and decide whether to regulate at least five or more contaminants on the list (called Regulatory Determinations).”

It will be interesting to see if the EPA takes the politically expedient course and adds crude 4-methylcyclohexanemethanol (MCHM, the Freedom Spill chemical) to the list. Not that MCHM is a wide spread drinking water threat, but it certainly is a visible one.
