Hi David,
Attached are the comments we received in response to the Public Notice. The comment that will need responding to is
the proposed 1:1 mitigation ratio. Based on the NCWAM ratings of medium and what I remember of the site, typically a
2:1 ratio would be required for the wetland impacts.
Also, I will need to get an updated plan drawing that has an accurate overlay/depiction of wetland impacts (and wanted
to verify the impact acreage as well). I didn't realize the plans put out in the Public Notice didn't accurately show the
wetland extent impacts (attached) and should look more like what was presented during the pre -application call
(attached) but using the corrected wetland boundaries (fig-6). Give me a call if this is confusing...

1. INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND REPAIR IMMEDIATELY AS NEEDED.
PULL THE SKIMMER TO ONE SIDE SO THAT THE SEDIMENT UNDERNEATH IT CAN BE EXCAVATED.
MAKE SURE VEGETATION GROWING IN THE BOTTOM OF THE BASINS DOES NOT HOLD DOWN THE
SKIMMER.
2. IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY JERKING
ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE DEBRIS AND
RESTORE FLOW. IF THIS DOES NOT WORK, PULL SKIMMER OVER TO THE SIDE OF THE BASIN AND
REMOVE THE DEBRIS. ALSO CHECK THE ORIFICE INSIDE THE SKIMMER TO SEE IF IT IS CLOGGED; IF
SO REMOVE DEBRIS.
3. IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE
OBSTRUCTION CLEARED WITH A PLUMBERS SNAKE OR BY FLUSHING WITH WATER. BE SURE AND
REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.
4. FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL PRECAUTIONS
SHOULD BE TAKEN IN THE WINTER TO PREVENT THE SKIMMER FROM PLUGGING WITH ICE.

The Cherokee Nation (Nation) is in receipt of your correspondence about SAW-2018-00173, and
appreciates the opportunity to provide comment upon this project. Please allow this letter to serve
as the Nation's interest in acting as a consulting party to this proposed project.
The Nation maintains databases and records of cultural, historic, and pre -historic resources in this
area. Our Historic Preservation Office reviewed this project, cross referenced the project's legal
description against our information, and found no instances where this project intersects or adjoins
such resources. Thus, the Nation does not foresee this project imparting impacts to Cherokee
cultural resources at this time.
However, the Nation requests that the United States Army Corps of Engineers (USACE) halt all
project activities immediately and re -contact our Offices for further consultation if items of cultural
significance are discovered during the course of this project.
Additionally, the Nation requests that the USACE conduct appropriate inquiries with other
pertinent Tribal and Historic Preservation Offices regarding historic and prehistoric resources not
included in the Nation's databases or records.
If you require additional information or have any questions, please contact me at your convenience.
Thank you for your time and attention to this matter.

David,
I'm reviewing the 401 modification request you recently submitted for the referenced project.
Based on another recent 401 project at the airport, it is my understanding that the stormwater
basins will require approval by NCDEMLR under the Phase II stormwater program. As the 401
impacts are directly tied to the size and shape of the proposed stormwater measures, please provide
documentation of DEMLR approval of the basins. I will place the project on hold until receipt of the
requested information. Please let me know if you have any questions or comments.
Thanks,

SUBJECT: Asheville Airport Area 1 Structural Fill
Wetland and UT to French Broad River, Buncombe County
SAW-2018-00173
Dear Ms. Fuemmeler:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed the
individual 404 permit application for the Asheville Airport Area 1 Structural Fill project, which
would impact 0.56 acre of wetland and 12 ft of an unnamed tributary (UT) to the French Broad
River in Buncombe County. Our comments on this application are offered for your
consideration under provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish
and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
This site drains to the French Broad River, which supports Blotched Chub (Erimystax insignis,
NC Significantly Rare), and father downstream, supports Appalachian Elktoe (Alasmidonta
raveneliana, US and NC Endangered). Wild trout reproduction should not be impacted by the
project, and a trout moratorium is not needed.
The Greater Asheville Regional Airport Authority proposes to place a permanent cap on existing
fill consisting of coal combustion residuals and convert two sediment basins to dry detention
stormwater basins to meet NC Department of Environmental Quality requirements. This will
involve culverting 12 ft of an UT to the French Broad River and filling 0.56 acre of wetland.
Both the stream and the wetland rate out medium with NCSAM and NCWAM, and a 1:1
mitigation ratio is proposed. We recommend that a ratio of at least 2:1 be used to mitigate for
these impacts. These features provide important ecological functions, especially as the
Endangered Appalachian Elktoe has recently been rediscovered in the French Broad River
downstream of the project area, and wetlands in the larger French Broad River valley are rare.

Public Notice
NOAA's National Marine Fisheries Service (NMFS) reviewed the project described in public notice SAW-
2018-00173, dated July 19, 2021. Based on the information in the public notice, we confirm the District's
determination that the proposed work would NOT occur in the vicinity of essential fish habitat (EFH)
designated by the South Atlantic Fishery Management Council, Mid -Atlantic Fishery Management
Council, or the NMFS. Present staffing levels preclude further analysis of the proposed work and no
further action is planned. This position is neither supportive of nor in opposition to authorization of the
proposed work. If further coordination on this action is needed, please let us know.

Hi Amanda,
My concerns for listed species at this location would be limited to potential impacts to NLEB, gray
bat, and app elktoe. But based on the info provided in the PN, it looks like there are no proposed
impacts to suitable habitats for listed species. My understanding is that there is no proposed tree
removal and proposed impacts to WoUS are at least 0.5 river miles upstream of the French Broad,
with forested riparian habitat and an unnamed tributary that add dilution flow upstream of the
French Broad confluence.
What are your thoughts on mitigation ratios? Please pass along NCSAM/NCWAM if the USACE you
believe >1:1 ratio is appropriate - we'd be happy to support you in that.
I am available anytime before 4PM today to discuss if you want: 828.337.2726
Stay healthy,
