EPA Information Quality Guidelines - Requests for Correction (RFC) and Requests for Reconsideration (RFR) Submitted to EPA

You will need Adobe Acrobat Reader, available as a free download, to view the files on this page. See EPA's PDF page to learn more about PDF, and for a link to the free Acrobat Reader.

Requests for Correction (RFC) are listed in order of date received, with most recent requests at the top. Requests for Reconsideration (RFR) are listed with their associated RFC. Click on the tracking number (e.g., RFC 05001) to view the request.

"EPA Related Correspondence" refers to additional correspondence between the requestor and EPA.

"Third Party Correspondence" is correspondence that EPA receives about an RFC or RFR from other interested parties. EPA's policy is to post such third party correspondence but to keep it separate from the original RFC or RFR . For information about EPA's handling of this type of correspondence, see the Third Party Correspondence page.
