Reference is made to your May 26, 2006 Department of the Army permit application in
which you requested a permit for impacts to stream channels and wetlands associated with the
proposed construction of a new runway, the expansion of an existing runway, and the
construction of associated infrastructure at the Charlotte Douglas International Airport,
Charlotte, North Carolina. The purpose of this letter is to provide you with comments received in
response to the Public Notice dated June 27, 2006 and request that additional information be
submitted to continue the review of your permit request.
By letters dated July 27, 2006 (enclosed), USFWS and EPA provided comments in
response to the Public Notice. Both USFWS and EPA commented that the proposed mitigation
plan is inadequate and that the applicant should provide mitigation at a 2:1 ratio for impacts to
important stream channels and a 1:1 ratio for impacts to unimportant stream channels. EPA also
commented that impacts to wetland areas should be mitigated at a 2:1 ratio versus the current
proposed ratio which is less than 1:1. We concur with the comments provided by USFWS and
EPA and request that the mitigation plan be revised to adequately compensate for impacts to
waters of the U.S. In accordance with Regulatory Guidance Letter 02-2 and Wilmington
District's Interagency Stream Mitigation Guidelines (Apri12003), compensatory mitigation to
offset impacts to waters of the U.S. typically require a minimum 1:1 ratio where practicable.
USFWS commented that the Phase II project area should be surveyed for the federally
endangered Schweinitz's Sunflower (Helianthus schweinitzii). USFWS recommended that
surveys be conducted in September 2006 and findings be forwarded to the service for review.
USFWS also noted a statement in the individual permit application (page 23, first paragraph) that
implies that waters of the U.S. between the proposed new parallel runway and runway extension
would be filled to eliminate wildlife hazards to aircraft. Based upon the impact tables and maps
submitted with the permit application, these jurisdictional areas were not calculated toward the
impact total. Please provide clarification regarding proposed impacts to these areas. Also, please
forward the re-issued Record of Decision when it becomes available.

Please be reminded that the requested information is essential for our permit review. If
you have any questions please contact Ms. Amanda Jones of the Asheville Regulatory Field
Office staff at telephone (828)-271-7980 extension 231.

Tom VV~lker
