Request for Nominations of Drinking Water Contaminants for the Fourth Contaminant Candidate List

On behalf of the American Chemistry Councils (ACC) OxoProcess Panel (Panel), I am submitting the attached comments regarding the Environmental Protection Agencys (EPA) proposed inclusion of 1-butanol (CASRN 71363) on the draft Drinking Water Contaminant Candidate List 4 (CCL4).2 As discussed in detail in the attached comments, the Panel believes that 1-butanol should be removed from the CCL4 due to 1-butanol exhibiting low risk to human health from environmental exposures. The Panel appreciates your consideration of these comments. If you have questions or would like to discuss further, please contact me at 202-249-6708 or by e-mail at angela_lynch@americanchemistry.com. Sincerely, Angela Lynch, MSPH, PhD Oxo Process Panel Manager Director, Chemical Products and Technology American Chemistry Council

To the Docket: The American Chemistry Council (ACC) appreciates the opportunity to comment on the U.S. Environmental Protection Agencys (EPA) Notice of Drinking Water Contaminant Candidate List 4 (CCL4)Draft under the Safe Drinking Water Act (SDWA), Docket ID No. EPA-HQ-OW-2012-0217, published in the Federal Register on February 4, 2015 at 80 Fed. Reg. 6076-6084. ACC supports the development of drinking water standards that protect public health and EPAs commitment to a sound scientific approach and evidence for the development of National Primary Drinking Water Standards (NPDWS). ACC understands, however, that the proposed listing may have future implications for chemicals being considered under EPAs Endocrine Disruptor Screening Program (EDSP). We appreciate EPAs consideration of our attached comments and would welcome working with the Agency on any issues pertaining to the CCL4. Should you have questions, please contact me by phone at (202) 249-6426 or by e-mail at rachel_meidl@americanchemistry.com. Respectfully submitted,
