[CPEO-MEF] EPA's response to Children's Health Committee letter on perchlorate

[Lenny Siegel <lsiegel@cpeo.org>]

On May 11, 2006, U.S. EPA Assistant Administrator for the Office of 
Solid Waste and Emergency Response, Susan Parker Bodine, sent a letter 
to Melanie A. Marty, Chair of the Children's Health Protection Advisory 
Committee, in response to that Committee's March 8, 2006 letter 
concerning the regulation of perchlorate. The full letter is available 
as a 152K PDF file from
http://yosemite.epa.gov/ochp/ochpweb.nsf/content/5112006.htm/$file/5112006.pdf.

Bodine's key points appear to be:

1. EPA's Preliminary Remediation Goal (PRG) of 24.5 parts per billion 
for perchlorate is protective because it is based upon a non-adverse effect.

2. The PRG is not a final cleanup level, but a "starting point for 
site-specific goals."

3. National data on perchlorate in food are insufficient to establish a 
relative source contribution factor for perchlorate.

4. EPA's Office of Water is evaluating, following its established 
process, whether the agency should promulgate a Maximum Contaminant 
Level (MCL) for perchlorate.

In other words, EPA is not changing anything in response to the 
Children's Health Committee letter.
