Dear Mr. Hagemeier

Your request for reconsideration under the HHSICDC Guidelines for Ensuring the Quality of Information Disseminated to the Public, submitted on behalf of the Chesapeake Energy Corporation is still under review. While our goal is to respond within 60 days to such requests, we are unable to do so in this case. We anticipate that a response will be forwarded to you by November 19, 2012. Please disregard a previous letter in which "December 19" was typed in error.

Thank you for your interest in the quality of information disseminated by CDC / ATSDR.

Sincerely,

/s/
