EPA Information Quality Guidelines - Requests for Correction and Requests for Reconsideration Submitted to EPA

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 tracking number.

"EPA Related Correspondence" refers to additional correspondence between the requester 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.
