Steve /Karen /Alan
As you all are aware we conducted a site meeting on March 15, 2012 Attendees
included Steve Kichefski, Alan Johnson, Ryan Shy and Kent Lackey from Black & Veatch,
and I At the site meeting it was discussed and agreed upon that during construction
coir matting would be used at stream crossings for bed and bank stabilization as
opposed to rip rap As a result the attached impact table has been revised to reflect
that no permanent stream impacts will occur for the project
Please let me know if there is anything further you need
Thanks,

Re Mount Mourne Gravity Outfall Mooresville Iredell County CH 11 1531
Dear Ms Robertson
On August 8 2011 we received notification from the State Clearinghouse concerning the above project
There are no known archaeological sites within the proposed project area Based on our knowledge of the
area it is unlikely that any archaeological resources that may be eligible for inclusion in the National Register of
Historic Places will be affected by the project We therefore recommend that no archaeological investigation
be conducted in connection with this project
Based on the submitted map the Southern Alternate Outfall Route may potentially have an adverse effect on
historic properties as the route appears to traverse two properties listed in the National Register of Historic
Places the George Houston House (ID 0026) and Wood Lawn (ID 0041) If this route is pursued please
forward a site plan showing the existing and proposed rights of way and /or easements property lines and
existing landscaping (indicating any landscaping proposed for removal or replacement)
We are aware of no historic resources that would be affected by the Proposed Route or the Northern Alternate
Route We have no comments on either of these routes
The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the
Advisory Council on Historic Preservation s Regulations for Compliance with Section 106 codified at 36 CFR
Part 800
Thank you for your cooperation and consideration If you have questions concerning the above comment
please contact Renee Gledhill Earley environmental review coordinator at 919 807 6579 In all future
communication concerning this project, please cite the above referenced tracking number
Sincerely

DATE August 18 2011
SUBJECT State Clearinghouse Project No 12 -0027 Mount Mourne [Sewer] Gravity Ouffall, Iredell
County
This correspondence responds to a request b) you for our review and comment✓ for the Environmental
Seopmg (ES) for the referenced sewer improvement. Biologists with the North Carohm Wildhfe
Resources Commission (NCWRC) are familiar with habitat values in the area The NCWRC is
authorized to comment and make recommendations which relate to the =pacts of this project on fish and
wildlife pursuant to Clean '%ater Act of 1977 North Carolina Environmental Policy Act, US Rational
Environmental Policy Act, Endangered Species Act (16 U S C 1331 1543 87 Stat 984) the Fish and
Wildlife Coordination Act (48 Stat. 401, as amended 16 U 6 C 661 667d) and/or Federal License of
W ater Resource Project Act (Federal Power Act -16 U S C 791a et seq ) as applicable.
The cover memo for the project indicates that the project will be approximately 2 6 miles of outfall
primarily located along West Branch Rocky River The submittal does not provide specific information
about the capacity of the outfall or indicate whether o not the project will serve existing communities or
serve to expand municipal scrviee areas and increase annexations
Our in office review of the project area found that the Bog turtle Glyptemys muhlenlergu (NCT FT 5 /A)
has been known from the area south of the terminal end of the protect near the stocky River
Additionally the Star nosed mole, Condylura crisrata (NCSC) is known from southwest of the sewer
Both of these species live in and depend on moist habitats creeks and wetlands The mole is known to
inhabit the banks of streams and open Ovate* impoundments The mole s habitath include lands near
coniterout and deciduous forests wet meadows and wetland marsh environs which could support the Bog
turtle if shallow mudd-, and without dense wood) veg tation
Based on our review we recommend that proloct proponents including contractors and construction
workers become familiar with the characteristics of the Bog turtle and the Star -nosed mole Should any
indnidual ammals be observed they should be protected from harm and this office ontacted to
deteimme how to restore the animal to its habitat or other disposition as aporopnate In addition, sewer
hies should not be located near streams and wetlands Instead public utilities should b- placed along the

edge of the floodpimn. This placement will also protect the utility from eroding and meandering stream
ecosystems which will save maintenance costs in addition, this office routinely recommends the
following for land use plaiimiag to indigate for developmental impacts that may follow the provision of
sewer
1 Prior to tree rmmoval and site clearing activities on a proposed development site and prior to local
site planting and zoning approvals, all jurisdictional waters and wetlands should be
professionally delineated pursuant to the Clean eater Act (CWA) usmg US Army Corps of
Engineers (COE) and NC Division of Water Quality (DWQ) cnteriz. This should be
accomplished as part of the developer's due diligence and site evaluation process CWA permits
are required for culverts for driveways parking lots road crossings as well as utility (including
sewer) lines that impact waters of the United States Should impacts ou ur to ,jurisdictional
waters or wetlands stormwater management should be provided Agricultural or forestry
exemptions must not be allowed when the ultimate use ofa pronerty will be a development
2. Jurisdictional streams wetlands and highly erodible areas and associated stream buffers should be
mauatamed or restored as contiguous undisturbed forested areas In watersheds supporting listed
aquatic species, stream buffers should be 100 for intermittent channels and 200 for perennial
channels In watersheds without listed species these buffers ,tiould be 50 and 100 resnei.tively
Buffers should be aermanently preserved as common conservation areas instead of subdivided.
Where practicable, impacted streams should be relocated using state -of the art natural channel
design and iiatiro vogetaatiun wstead of piping the streams as is typically done Local authorities
should ]teen sewer Imes, w ct lines. and other utilttim-m;t -of riparian zones and buffers
Placement should occur along the floodplain fringe
3 For savam crossings culverts 48" diameter or Iarger should be buried a foot into the streambed.
Culverts less than 48" diameter should be brined to a depth equal to or greater than 200/ their Ride
to allow for aquatic life passage These measurements must be based on natural thalweg depths
4 Stormwater management should maintain, to the extent possible, pre development hydrographic
conditions Storinwater control treasures should be implemented bef6e impervious surfaces
reach 10% for most watersheds and 6 % for watersheds with listed species oresm downstream
Low Impact Development (LID) techniques are encouraged for all new developments and
redevelopment efforts If impervious area exceeds t-n (10) perrent stormwater management
strategies that maintain or restore pre development hydrograph conditions are recommended.
Information on Low Impact Development (LID) practices and measures can be found at
wwwlowirnpactdevelnPmcntare hth/ iwwvu, oiao� /otvovv /nns/lid/lidnatlpdf and
rip /nt wv stonriwatercenter nev Mamtenance of the pre - disturbance hvdrograph is needed to
-educe downstream channel de,tabilization flooding and streambank erosion Stormwater
mamgement ponds should be forested (excluding dams) with native plants to reduce thermal
impacts to waters
5 Fill m Federal Emergency Management Agency designated floodplains as well as CWA
jurisdictional water floodplains should be prohibited or no net loss strategies should be used
This is an essential and important maintenance component of stormwater management Entire
noodplain areas should be protected as undisturbed forested areas to benefit local air and water
quality as well as provide habitat valum
6 Sediment and erosion controls should meet NC Division of Water Quality requirements for the
classification of watersheds Preterably sediment and erosion control measures should adhere to
the design standards for sensitive watersheds (15A NCAC 413 0124)
7 Project proponents and local government officials should visit our website at
http //wuw ncciildlife ore /pg07 Wildl feSpceiesCon�pg76 imRctspdf to learn more about
historical or incremental diminishment of habitats also, iatec with increased imperviousn,ss.
Mitigative measures can significantly reduce these negative impacts and, in some instances

resto a some of those lost or diminished environs Project proponents shoule visit Audubon
In ernational at htM //,%-w-v auduboninternational or and the National Wildlife Federation at
hMJfwww nwf,ora to learn more about wildlife friendly certifications and standards Ming
these or similar protectrt a entma should be a preferred goal for development
If the sewer unprovements Kill. have the capacity to open up a much larger area(s) for annexation and
development. an Environmental Assessment (EA) should be proviced that addresses the issues indicated
above as well as the information requested in the attachments below If the project is essentially limited
to serving existing development and little more, an Environmental Review (ER) at th„ community lo-, 01
may suffice providing the measures above are implemented as applicable and practicable (previously
recommended for the Ptvsbytenan Pump Station, West Branch Gravity Outfall)

General Guidelines for Environmernal Reviews
Due to staff limitations, thus standandiwd responw was developed. Although some of the
information, requests and comments may not be applicable to certain projects these guidelines
should facilitate preparation of fish and wildlife Environmental Assessments (EA) or
Environmental impact Statements (EIS) In addition to addressing site specific concerns the
envtronmental document should include a detailed assessment of existing natural resources
within the areas of potential development and should discuss the potential of mitigating
development impacts to wetlands streams and high quality fl odplain and upland habitats. To
provide a meaningful review of the EA or EIS prepared for the project(s) secondary and
cumulative impacts, we request that protect consultants and sponsors provide the following
information
1) Project proponents should provide equal attention to direct project impacts and indireyt
impacts that the project will precipitate
2) Description of waters and/or wetlands affected by the project(s) Description of fishery
mid wildlife resources within the project, area, mcludmg a listing of federally or state
designated threatened endangered or special concern animal and plant species in the
project area and any areas that may be impacted by secondary or cumulative impacts
within the affected sub-basin(s) A listing of designated species can be developed
duough consultation with the North Carolina Natural Hentage Program or the US Fish
and Wildlife Service
3) Project map identifying wetlands and mten=ent as well as perennial stream in the area
Idontification of wetlands may be accomplished through coord- nation with the U S Army
Corps of Engineers If the Corps is not consulted the person delineatmg wetlands should
be identified and criteria listed
4) Description of activities that will oeci r within streams and wetlands, such as fill or
channel alteration Acreage of wetlands impacted and linear fleet of stream channels to be
relocated, channeled culverted or disturbed by some other means by alternative project
dei-i`ans should be listed.
5) Description of project site and non wetland vegetative communities
6) Description and cover type map showing acreage of upland wildlife habitat imptwted by
the project
7) Discuss the extent to viluch the propct(s) will result in loss degradation, or
fragmentation of wildlife habitat
8) Discuss any measures proposed to aFOnd or reduce iim its of the project or to mitigate
for unavoidable habitat losses

MOMt Mowae GmVity Outfall Page 5 August 18 2011
9) Discuss the cumulative impacts of secondary development Facilitated by the proposed
utility improvements and any mterrelated infrastructure projects especially the unnaets to
water Quality and habitat in the impacted waterched(s) Such discussion should weigh the
economic benefits of such growth against the costs of associated environmental
degradation
(a) include specific measures that will he uwd to address stormwater at the source
Include specific requirements for both resideiltlal and mdustnal developments and BNIPs
that will be required
(b) Include specific measures that will be used to protect stream comdois, riparian habitat
and a mmimum of a 100 -veer floodplam. Since all streams have floodplains, it is
important to avoid :ill in active i%odnlam areas not just the 100 year floodplam
(c) Include specific measures that will be implemented to promote water conservation
and wastewater reuse
(d) Include a discussion of any other local ordinances or programs (e g , industrial
pretreatment, nifiltration and inflow management farmland preservation, habitat
restoration/preservation, and recycling) that will mitigate the impacts of development.
10) Discuss the use of any mitigation, preservation, deed restrictions, and conservation plans
and maMement objectives These should include detailed site deserimtions and maps
A determination concerning which agency or entity (e g land conservancy) will own and
manage the easements or property should be included-
Note A list of document preparers should be provided that provides each individual's
professional background and qualifications

Utihty 1LiMe and Sewer ILme Avoidance and Minimisation Recommendations
Meanifts. to avoid or mmimize impacts to sensitive resources including wetlands, should be
implemented dung all phases of construction asbociated with the area.. When mo=ts to
wetlands (and waters) are unavoidable we will recommend mitigation of the Iosses In addition
to prvvidmg wildlife habitat wetland areas perform the important functions of flood control and
water quality ptntectirm Whenever pncsible utility Imes should be placed along existing right
of wa} s along roads and previously impacted corridors Pumping may be economically feasible
where direct or secondary impacts can be avoided in sensitive habitats. To avoid or mimmaae
stream and wetlaiid impacts during construction of utility lines we offer the followmg non -
prioritized general recommendations that should he incorporated unto project plans
1) Construction corridors should be no wader than absolutely necessary The 401
certification for Nationwide 12 stipulates that wetland construction corridors art; iwt to
exceed 40 feet and permanent maintained corridors are not to exceed 10 feet except at
access points The NC Division of Rater Quahty's 441 Certification for uttflaty lanes
should be followed speeaficaliv for all jurisdictional impacts Where crossings are
necessary, sewer lines should cross streams at right angle to mm,mme impacts to
riparian areas Restored streams and stream bank�, should be punted with autoehthonous
(native) plants Nice silky dogwood, rhododendron, dog hobble red maple s111ry willow,
tag adder, black willow sycamore, ever birch, or other native woodv species Riprap
mad be used to stabilize the bank in the area of the ordinary high water stage and
vegetation (bioengineering) should be used above this stage Aquatic life passage must
not be hindered during low flows upon protect completion. Directional boring is the
ui efetred metbod of crossing1urrsdictional waters, and wetlands
3) Utility lines crossing streams should be tuned in the stream bottom or attached to
eostmg lodges to maintain fish movement upstream and downstream and prevent debris
from colleLtuag at the pipe and causing a hydrologic change Ah a do not recommend
installing priers in a stream channel to support a sewer line
4) If concrete wall be used, work must be accomplished so that wet concrete does not
contact stream water This will lessen the chance of altering the stream s water chemistry
and causing a fish kill.
5) An undisturbed buffer zone should be left between streams and all construction. We
prefer a buffer zone of at least DUO feet to coniml sedunentation into streams provide
shade and maintain a travel corridor for wildlife Buffers should also be lefl along
mtermitteirt drains or streams To the maximum extent practicable utility lanes should be
located on the edge of tloodplams and away from riparian areas, wetlands and streams
ti) Temporarily disturbed wetlands should be reseeded with annual small grains appropriate
for the season (e g annual oats, mallet, or wheat) and be allowed to revert to native
nattual wetland vegetation

Mount Moaunc Gmvity out'fa21 Page 7 August 18 2811
7) A portion of the upland nght -of way (nununum of one acre) should be planted with
native warm season grasses ladmo clover, and/or partridge pea to provide food and
additional habitat fDr wildlife Autochtbonous l-w —fts should be used to the maximum
extent nractscable Routmely grown agt7_cultu*al annual plants Ike oats, wheat or barley
axec -table for tempma nursery cover.
8) Slash and/or large trees avat`lable form corridor construction through forested and stream
corridors should be placed along the permanent right- of -way ui the form of brush piles
and downed logs to pTovlde cover and nestv4g habitat for wildlife
9) If necessary ROW areas should be mowed not more than once every two (2) to three (3)
years Mowing should occur between mid -March and mud -April to avoid disturbing
wildlife utilizing the project condor during the crmcal stages of nesting and rearnrg as
wcll as to ensure winter covet
10) Stringent erosion control pleasures should be rmplentented where soil is disturbed and
maintained until protect completion
11) Temporary or permanent herbaceous vegetation should be planted on all bare soil wrtiun
five (5) to ten (10) days of ground disturbing achvitres to provide long -term erosion
control. We prefer a "seed as you go strategy rather than allowmg a large area to remain
bare
12) To repeat an important pond, all utilities should be located away from stream banks and
rwarran buffer zones Running these along floodplam edges and contours should be
accomplished whenever possible
