CONDITIONS
Mill Creek Stream Rehabilitation (State Employees Credit Union, Sylva)
Dear Mr. Schwalm and Mr. Bartlett:
You have our approval for the impacts listed below for the purpose described in your
application dated May 24, 2016, and received by the Division of Water Resources (Division) on
May 26, 2016 and additional information received via email on August 5, 2016. These impacts
are covered by the attached Water Quality General Certification Number 3885 and the
additional conditions listed below. This certification is associated with the use of Nationwide
Permit Number 13 once it is issued to you bythe U.S. Army Corps of Engineers. Please note that
you should get any other federal, state or localpermits before proceeding with your project,
including those required by (but not limited to) Sediment and Erosion Control, Non -Discharge,
Water Supply Watershed, and Trout Buffer regulations.
This approval requires you to follow the conditions listed in the enclosed certification(s) or
.general permit and the following additional conditions:
1. The following impacts are hereby approved provided that all of the other specific and
general conditions of the Certification are met. No other impacts are approved,
including incidental impacts. [15A NCAC 02H .0506(b) and/or (c)]

and the various sites shall be stabilized with natural woody vegetation (except for the
approved maintenance areas) and restored. to prevent erosion.
11, All temporary pipes/ culverts/ riprap pads etc, shall be installed in all streams as outlinedin
the most recent edition of the North Carolina Sediment and Erosion Control Planning and
Design Manual or the North Carolina Surface Mining Manual so as not to restrict stream flow
or cause disequilibrium during use of this General Certification.

be carried off by wave, currentaction or stream flows and consist of clean rock or masonry
material free of debris or toxic pollutants. Rip -rap shall not be. installed in the streambed
except in specific areas required for velocity control and to ensure. structural integrity of bank
stabilization measures.

including riparian buffers, but Is restricted to no closer than 10 feet from top of bankof
streams. Any fertilizer application must comply with all other Federal State and Local
regulations.
15. Applications for riprap groins proposed in accordance with 15A NCAC 07H, 1401 (NC

SUBJECT: Mill Creek Stream Restoration
Mill Creek, Jackson County
Dear Mr. Brown:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an
application to restore 200 feet of Mill Creek behind the NC State Employees Credit Union office
in Sylva, Jackson County. I have visited the site multiple times in the past two months. 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 project should not affect trout and the activities do not need to be avoided during the trout
spawning moratorium. However, the site is approximately 1.5 miles upstream of the Tuckasegee
River, which supports a number of listed and rare aquatic species in the vicinity of the project,
including the Appalachian Elktoe [Alasmidonta raveneliana, US Endangered (E), NC E], Eastern
Hellbender [Cryptobranchus alleganiensis, US Federal Species of Concern (FSC), NC SC
(Special Concern)], Wavyrayed Lampmussel (Fasciola lampsihs, NC SC), and Wounded Darter
(Etheostoma vulneratum, US FSC, NC SC). This portion of the river is known as the
Tuckasegee River Aquatic Habitat, a natural area rated Very High due to the richness of rare
species it contains.
The application proposes to restore a section of Mill Creek that was channelized during recent
unpermitted activities. The channel was dug down to expose a clay substrate, and it is now
straight and has vertical banks. The design proposes to lay back the left bank to a 3:1 slope; it is
unclear if the right bank will be sloped back. Neither profile nor pattern will be adjusted. The
application states that riprap would be used to stabilize the banks, as the soils that remain would
not support vegetation. Trees, shrubs, and a riparian seed mix would be planted on top of the

stream banks. Sediment that has been lost to the channel during stream channelization activities
is proposed to be removed after the stream restoration project is completed.
We recommend that the project be redesigned and a natural channel design approach be used.
The design should consider channel pattern, dimension, and profile, using reference reach
parameters. Appropriately sized and designed instream structures can be used to adjust the
profile without negatively impacting aquatic organism passage, Biostabilization should be used
on stream banks instead of riprap; soils may need to be imported and/or amended in order to
foster native vegetation on the banks.
We recommend incorporating as many native shrubs and trees as possible into the project, as
native woody vegetation will provide long-term bank stabilization, keep water temperatures cool,
and provide wildlife habitat.
We offer the following recommendations to minimize impacts to the aquatic community:
1. The project design should incorporate natural channel design concepts, and pattern,
dimension, and profile should be considered. Bioengineering techniques should be used to
stabilize stream banks instead of riprap.
2. Work should be accomplished as quickly as possible and vigilance used in sediment and
erosion control during site preparation, construction, and clean up. Disturbed areas should be.
seeded, mulched and/or matted as soon as possible, preferably at the end of each work day.
3. In-stream restoration should be performed in the dry.
4. As sediment lost from unpermitted activities is moving downstream, we recommend
removing fine sediments as soon as possible instead of after the project is complete.
5. Any erosion control matting used be free of plastic or nylon mesh, as this type of mesh
netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that may
last for years. -
6. We recommend that the project incorporate as many native trees and shrubs as possible. The
planted width should be as wide as infrastructure allows.
Thank you for the opportunity to review and comment on this project. Please contact me at
