Dave,
Attached are the following items pertaining to the revised PCN for the Dan River intake project:
1) Revised PCN form, with changes highlighted in yellow
2) Revised PCN form, without highlighting
3) Revised figures 6, 7, 11 A -D, plus new figures 11 E -F, 12, 13, and 14.
4) Google Earth KML file of the intake property, showing revised streams, wetlands, and proposed construction.
5) Google Earth KML file of the raw water line, showing revised streams, wetlands, and proposed construction.
#5 is what I sent to DCR -SHPO on March 6 regarding their request for a more detailed map of the construction corridor
near the historic sites. I expect I'll be getting a response from Renee soon. I have not yet received any response from
US -FWS regarding my Oct 27 letter about endangered species impacts, but we have discussed intake velocity and
screen mesh via email with FWS and NC -WRC, and the engineer has agreed to meet the 0.5 ft/sec and 1.0 mm mesh
criteria.

Gerald,

Thanks for meeting in the field for the Jurisdictional Determination verification last
Wednesday, 2/11/2015. As promised I am including a list of changes made for the JD as well
as remaining needs for permitting of the above referenced project:
1) Stream 1 is a good quality resource that appeared perennial although DWQ forms have not
been submitted. It was noted that the 102 if of stream impacts listed in the PCN was
only pipe length, and must be converted to actual stream length within the pipe /fill
footprint. Further, the upstream rip rap pad likely only needs to be brought back to
original grade and contour rather than act as an above grade dissipater pad; if this
is the case then please specify and change the upstream riprap pad to a temporary
impact. The downstream riprap pad appears to be a true dissipater pad and must be
included as a permanent impact, added to the impact total of the piped section of
stream to determine if compensatory mitigation is required.
2) Wetland W -1 was documented as having a surface water connection to the Dan River, and
thus is considered to be adjacent to the Dan River and subject to CWA Sec. 404
jurisdiction. As this wetland had not been GPS'd at the time of PCN submittal it is
possible that proposed impacts may require updating in the PCN. If proposed wetland
impacts are greater than or equal to 0.1 acre then compensatory mitigation will be
required.
3) As discussed previously the water line portion of the project must be included in order
to justify a single and complete project. A conceptual plan has been provided that
places the water line within NCDOT ROW, though not necessarily in road base materials,
specifying particular sides of NC 62 until the eastern extent of the project area
where the proposed pipeline extends through areas of undeveloped land.
a. A new area of jurisdictional stream and /or wetland was identified on the west
side of NC 62 south of High Rock School Road. This area must be added to the
waters of the US field sketch /map and, if necessary, added as a proposed impact
on the PCN.
b. Streams S2 and S3 were observed to possess high aquatic function. As such,
avoiding these features through directional drill techniques is required unless
it is not practicable.
c. Construction and maintenance corridors for the proposed water line must be
described. If any forested or shrub /scrub wetland areas are proposed to be
permanently maintained as herbaceous wetlands it must be reflected on the PCN.
d. Detail sheets of wetland and stream crossings are required for the proposed
water line crossings. Typical sections including temporary impact restoration
plans were discussed in the field as potentially satisfying this requirement.
4) As requested in my 12/8/2014 email request for additional information:
a. Please forward the USFWS response once received regarding the Roanoke logperch
and James spinymussel, as we must reach an effects determination (and
potentially consult with the USFWS) prior to verifying the use of a Nationwide
Permit. (Nationwide Permit Condition # 18)
b. Regarding cultural resources, please provide more information on the location of
the properties of concern versus the location of the proposed impacts, as this
will determine the level of consultation required from the USACE. (Nationwide
Permit Condition # 20). Please see the attached document for SHPO information
needs. Please provide SHPO's response to your additional information submittal
once received.
The above information must be received before I can proceed with verifying the use of
Nationwide Permit 12
(http: / /www.saw.usace. army.mil/ Portals /59 /docs/ regulatory /regdocs /NWP2012/NWP12_3-
23.pdf). Please submit the requested information (via e -mail is fine) within 30 days of
receipt of this Notification, otherwise we may deny verification of the use of the
Nationwide Permit or consider your application withdrawn and close the file. If you have
any questions please let me know.

3. Project Description
3a. Describe the existing conditions on the site and general land use in the vicinity of the project at time of this application
The 22 -acre intake property is bounded by the Dan River to the northwest, a Duke Energy powerline to the south, and an
unnamed tributary to the east and north. Elevations on the site range from 350 feet at the edge of the river (OHWM) to 480 feet
on the highest ridge. The property is roughly two- thirds forested and one -third cattle pasture. The forested areas support a mix of
mesic hardwood and alluvial forest trees including Sweetgum, Red maple, Tulip poplar, Musclewood, Box elder, Sugarberry,
Willow oak, Red oak, Beech, Loblolly pine, Eastern redcedar, Sycamore, and Paulownia. An abandoned railroad embankment
(tracks have been removed) parallels the river about 140 ft from the edge of water (OHWM). A steep forested ravine in the
west - central portion of the site contains a small riparian wetland mostly on the southeast side of the railroad embankment where
drainage is impeded. This wetland drains through a culvert under the railroad embankment onto the levee, where surface flow
disappears into the soil. The river bank at the intake site is steep, with no fringe wetland. Land uses adjacent to the intake
property land uses are rural - residential and agricultural.
The proposed access road corridor from NC -62 westward to the intake site traverses 980 feet of pasture, then crosses a small
perennial stream at the east edge of the intake site. This small stream flows northward into the Dan River near the edge of the
property. The stream bed comprises bedrock steps and pools with sand and silt, and the stream banks are relatively steep, with
no fringe wetland in the vicinity of the road crossing. The upper reach of this stream (south of the proposed road crossing) is
partially impounded by a farm pond located between the powerline and the proposed access road.
The proposed raw water line corridor follows NC -62 along a ridgeline from the intake site southward to Moorefield Rd south of
Yanceyville (about 12 miles), then westward another one mile to the existing Yanceyville WWTP. Adjacent land uses along
NC -62 are primarily rural residential and agricultural, with some commercial and institutional development in the Town of
Yanceyville near the southern end of the project. Several headwater streams and seeps are located adjacent to NC -62 along this
corridor, where the construction alignment (preliminary) was selected to avoid and minimize impacts to these features. The last
mile of raw water line, from Moorefield Rd west to the Yanceyville WTP, traverses mostly upland hardwood and mixed pine -
hardwood forest (some areas recently clearcut), with five south - flowing streams. Several homes are located along Moorefield
Rd, mostly on the north side. The off -road water line segment west of Moorefield Rd crosses NC -WRC Gamelands (1500 ft),
the Yanceyville WWTP property (650 ft), and private undeveloped land (1,700 ft).

PCN Form — Version 1.3, Dec 2008

3b. List the total estimated acreage of all existing wetlands on the property:
RJG &A biologist Gerald Pottern examined the intake site and raw water line corridor for wetlands and waters during Oct 2014,
and re- visited these sites with ACE agent David Bailey and DWR agent Sue Homewood on 11 Feb 2015. The currently
proposed intake site is about 600 ft northeast of the intake location depicted in the 2006 SEPA -EA wetland maps. The ravine in
the middle of the intake site contains a small riparian wetland mostly on the east (upslope) side of the old railroad embankment.
The downstream portion of this wetland west of the RR culvert outlet is a linear seep, flowing about 65 feet toward the river
before disappearing into the soil on the levee, about 60 feet from the edge of the river. The eastern portion is 0.073 acre and the
western portion is 0.011 acre; total = 0.084 acre. Its connection with the river is underground, and its elevation (approx 365 ft)
is about 15 feet above normal river stage elevation. Wetland vegetation (on both sides of the railroad embankment) is
predominantly shrub and herb vegetation with few trees, but the wetland is well shaded by large trees rooted in the adjacent non -
wetland forest.
The raw water line corridor along NC -62 between the intake site and Moorefield Rd (worst -case preliminary alignment,
extending 10 -ft beyond highway R -O -W) passes adjacent to several headwater seep wetlands, but the jurisdictional portions are
all are 30 ft or more beyond the road right -of -way and thus beyond the impact area. Some of these drainage ways are depicted
as wetlands or "wet ditch" impacts in the 2006 EA, but the upper portions within the proposed impact corridor were found to be
non jurisdictional during the Feb 2015 field verification meeting (PCN figures revised accordingly). From Moorefield Rd west
to the Yanceyville WTP, the off -road preliminary corridor (20 -ft wide) crosses two additional alluvial wetlands (total 0.0405
acre in construction corridor). These wetlands are contiguous with streams.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
The intake property includes 2,300 feet of frontage along the southeast (right) bank of the Dan River, most of which is forested.
The near -shore river bed is predominantly silt and fine sand; the deeper off -shore river bed was not visible. The intake property
also includes 900 linear feet of a 5 to 8 foot wide (ave 6 foot) small perennial tributary flowing northward into the Dan River.
The bed of this stream is primarily bedrock with silt and sand deposits in pools; the stream banks are forested.
The NC -62 roadside raw water line corridor between the intake site and Moorefield Rd (preliminary alignment) crosses one
intermittent headwater stream (5 ft wide) on the west side of NC -62, about 0.6 mile north of Zimmerman Rd. From Moorefield
Rd west to the Yanceyville WTP, the off -road corridor crosses five southward - flowing tributaries of Country Line Creek, with
widths of 15, 6, 10, 12, and 5 feet. Using a 20 -ft wide temporary disturbance corridor, the total stream channel length within the
raw water line corridor (excluding the stream on the intake property) is approximately 135 feet.
3d. Explain the purpose of the proposed project
The Town of Yanceyville has purchased a 22 -acre site along the Dan River near Milton in northeastern Caswell County to
construct a public raw water intake. Yanceyville, Caswell County, City of Roxboro, and Person County established an inter -
local agreement in 2003 to develop this intake as a long -term regional water source to serve the two counties and their
municipalities. The intake channel, pump station building pad, and access road off NC -62 are being designed and scheduled to
be built during summer -fall 2015. The pump house, pumping facilities, and raw water lines will be designed and built at least 5
to 10 years later as water demand grows. For budgeting purposes the municipalities plan to build just the Phase 1 facilities at
this time (intake channel, building pad, and access road). Eventually raw water lines to Yanceyville's and Roxboro's existing
WTPs will be built, and a small package WTP will be installed on the intake property with a potable water line connecting to the
Town of Milton's distribution system. Roxboro and Yanceyville currently rely on impoundments constructed on smaller
streams ( Roxboro's City Lake and Yanceyville's Farmer Lake) which have adequate safe yield for now, but will eventually need
to be supplemented as the population grows in Caswell and Person Counties. Milton relies on a public groundwater well system
with limited yield. The Dan River intake will provide a much greater safe yield and is expected to meet the region's water needs
for 50 years and beyond.

PCN Form — Version 1.3, Dec 2008

3e. Describe the overall project in detail, including the type of equipment to be used:
Intake Site Construction Sequence: 1. Install erosion and sediment control features along the intake access road corridor, and
begin grading the access road (see plan sheet). 2. Clear the S1 stream crossing area and dewater this stream segment with
temporary cofferdams and bypass pumps; cofferdams will placed within the footprint of the proposed permanent fill (riprap) and
will not require any additional temporary stream impact length. Dewatering may not be needed if construction can be completed
while the stream is naturally dry. 3. Excavate the stream bed as needed to install a permanent 54" diam RCP culvert (102 feet
long), concrete headwalls, and riprap approach at the culvert inlet (10 ft riprap at stream -bed grade) and outlet (30 ft riprap,
above grade dissipator). 4. Place fill for the access road over the culvert, allowing construction vehicle access to the western
part of the intake property. 5. Install erosion and sediment control features on the intake site, and clear and grub the western
segment of the proposed access road, the pump station area, and intake channel area. 6. Excavate the intake channel, except for
the last 40 feet closest to the river, and grade a 12 -ft wide access road on each side of the channel. 7. Armor the channel slopes
with articulated block from the bed up to OHWM elevation (341 to 350 ft), and install Curlex or similar matting to support grass
establishment on the channel access roads and upper slopes (350 to 370 ft). The partial intake channel will serve as a temporary
stormwater basin during the remainder of construction (see plan sheet). 8. Use the excavated soil to complete grading along the
access roads, pump station site and parking area. 9. Clear and grub the borrow & fill areas north and south of the access road,
taking additional fill material as needed for access roads and intake site grading. 10. Construct the concrete section of the
intake channel and adjoining base pad for the future pump station. 11. All disturbed soil areas on the intake site will be
stabilized with matting and vegetation prior to excavation of the final intake channel tie -in to the river. 12. Install a temporary
cofferdam approximately 175 feet long parallel to the river bank using approximately 260 cubic yards of surge stone, concrete
Jersey barriers on top of the surge stone, and polyethylene sheeting anchored with additional rock. 13. Dewater the near -bank
construction area (approximately 155 feet long and 10 to 15 feet wide) using sump pumps and silt sacks or other appropriate
silt - removal devices. 14. Remove accumulated sediment from the partial intake channel. 15. Excavate the dewatered river
bank to create a 2:1 slope (approx 2,250 cu.yds) and tie -in to the previously excavated channel, and install articulated block on
the lower slopes and Curlex or similar matting on the upper slopes as specified in step 7 above. 16. Remove the cofferdam
materials down to the natural river bed and allow the dewatered area and new intake channel to fill from the river.
Raw Water Line Construction Sequence:
This description of raw water line construction is based on preliminary plans. Final alignment selection and design is not
expected to occur for another 5 to 10 years, as the municipalities expect to have adequate water yield from existing sources until
then. Other new construction during that time (road improvements, utilities, adjacent development), new construction
technology, and changes in NC -DENR standards could affect the final alignment selection and design process. The preliminary
alignment presented in the EA and this PCN was selected to minimize stream and wetland impacts. It follows the northwest
side of NC -62 from the intake access road southward for 9.7 miles, then crosses to the southeast side of NC -62 for the remaining
2.5 miles from that point (just west of Bear Land Trail) southwest to Moorefield Rd. Current plans call for installing the
roadside portion of raw water line just inside the NC -62 right -of -way, and using bore-and-jack technology at all stream and
wetland crossings along NC -62 and the off -road segment between Moorefield Rd and the Yanceyville WTP (six streams and
two wetlands). However, bedrock or other constraints may limit the feasibility of trenchless construction methods in some
areas. Consequently, wetland and stream impacts listed in this PCN are based on potential "worst -case" conditions: roadside
construction extending 10 ft beyond the road right -of -way, and open trench installation at all stream and wetland crossings.
Actual impacts will most likely be less than the impacts described herein. Since the 404 permit authorization will most likely
expired by the time the water line is designed, a revised and more detailed PCN application will be submitted at that time.
1. Install appropriate erosion and sediment control features along each pipeline segment. 2. Perform clearing of the
construction corridor where needed (many roadside segments are bordered by non - forested land where minimal clearing is
needed). 3. Excavate the pipeline trench to the appropriate depth, with appropriate side slopes and /or bracing, and stockpile the
topsoil. 4. Install bedding stone, then position each pipe segment and seal it to the previously placed segment. 5. Backfill the
trench, replace topsoil, and seed the disturbed soil with appropriate grass or other groundcover seed mix. 6. Segments crossing
streams and wetlands will be installed using bore-and-jack or other trenchless technology if feasible and cost - effective; to be
determined on a site -by -site basis. If open- trenching is used at streams or wetlands, the area will be dewatered with portable
cofferdams and pumps prior to excavation. 7. Temporary culverts with earth or stone fill or timber mats may be needed for
vehicle access at some of the stream and wetland crossings between Moorefield Rd and Badgett Sisters Parkway (east of the
WTP). Any temporary fills in these areas will be removed upon completion of the crossing and disturbed areas reseeded with
appropriate groundcover. 8. A permanent 20 -ft wide mowed corridor will be maintained along the off -road segment between
Moorefield Rd and Badgett Sisters Pkwy.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The selected intake site has a natural ravine with a lower bank profile than other sites along the river bank, thus minimizing the
required excavation and land disturbance, and reducing the potential for bank erosion into the river during construction. A small
riparian wetland in the ravine and a small stream crossing along the access road are unavoidable. The intake velocity and screen
design will meet NC -WRC guidelines for fish protection in the Dan River (less than 0.5 ft/sec velocity at the intake screen and 1
mm screen openings). NC Division of Land Quality has reviewed and approved the erosion and sedimentation control plan for the
Phase 1 intake construction.
The Yanceyville raw water line will be mostly routed along NC -62 which follows a ridgeline between watersheds, and the proposed
alignment (side of road) was selected to avoid and minimize stream and wetland impacts. The off -road segment from Moorefield
Rd to the WTP will use a narrow construction corridor (20 feet). Bore-and-jack or similar trenchless methods will be used for all
stream and wetland crossings wherever practicable, but final design and construction methods will not be determined for at least 5
years. Water line impacts described herein are preliminary and based on worst -case scenario (open trench installation).

4. Sewage Disposal (DWQ Requirement)
4a. Clearly detail the ultimate treatment methods and disposition (non- discharge or discharge) of wastewater generated from
the proposed project, or available capacity of the subject facility.
This project will not generate any on -site sanitary wastewater. Raw water drawn at this intake will eventually be treated and used
by Yanceyville, Roxboro, and elsewhere in Caswell and Person Counties as their water distribution systems expand. The
municipalities and counties will eventually need to expand their wastewater collection and treatment systems as needed to keep pace
with potable water system expansion.
5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or habitat?
❑ Yes ® No
5b. Have you checked with the USFWS concerning Endangered Species Act impacts?
® Yes ❑ No
5c. If yes, indicate the USFWS Field Office you have contacted.
® Raleigh ❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
US -FWS and NC -NHP online databases report two federally endangered species likely to occur in Caswell County: The
Roanoke Logperch occurs upstream in the Dan, Smith, and Mayo Rivers in Rockingham County and in the short segment of
Dan River in the northwest corner of Caswell County, upstream of Danville, VA. The James Spinymussel occurs upstream in
the Dan and Mayo Rivers in Stokes and Rockingham Counties, and is listed as "potential" in Caswell County, where it might
occur in the short river segment in the northwest corner of the county. There is no report of either Roanoke Logperch or James
Spinymussel from the Dan River downstream of Danville VA, where the river gradient becomes flatter and more sand -
dominated, with few areas of gravel and cobble habitat. Based on the habitat change, lack of species records, and the recent
coal ash spill, it is unlikely that these two species presently occur in the Dan River in northeastern Caswell County. RJG &A
submitted a scoping letter to US -FWS and NC -WRC, and we will forward their responses to ACE and DWR upon receipt.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?
❑ Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
NC -DMF and NC -WRC have not designated any Essential Fish Habitat in Caswell County.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal governments have
designated as having historic or cultural preservation status (e.g., National Historic Trust
® Yes ❑ No
designation or properties significant in North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
The NC State Historic Preservation Office (SHPO) reviewed the project description and maps submitted by RJG &A and responded
(04 Nov 2014. attached) that the project construction area is unlikely to have any significant archaeological resources, and that an
archaeological survey is not needed. Four historic sites listed in the National Register of Historic Places occur along NC -62 and
could be affected by raw water line construction: William Poteat House (CS0013), Melrose (Williamson) House (CS0070), Lea's
Tavern (CS0077), and NC -62 Rural Historic District (CS0074). SHPO requested detailed mapping of the water line construction
corridor for their use in determining potential effects of the project. RJG &A provided a Google Earth KML file to SHPO showing
the proposed construction corridor edge (TIC -62 right -of -way) and historic site locations, and explained that detailed plans for the
raw water line would not be prepared for at least 5 years, and the applicant would need to coordinate again with SHPO at that time.

PCN Form —Version 1.3, Dec 2008

8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA- designated 100 -year floodplain?
® Yes ❑ No
8b. If yes, explain how project meets FEMA requirements:
The intake channel excavation will create a net increase in flood storage capacity within the Dan River floodway and will not
cause any rise in flood elevations upstream or downstream. A small area of floodplain in the ravine will be raised slightly for
the pump station pad, but this minor fill will be offset by more than 50 times more cut volume.
8c. What source(s) did you use to make the floodplain determination? Caswell County FIRM Panel #9031 (viewed on
ncfloodmaps.com and jris.nc.gov) 100 -yr flood hazard elevation (zone AE) is 379.8 feet at the intake site, and 379.5 feet on the
tributary downstream of the intake access road crossing. There is no other FEMA mapped floodplain along the remainder of
the raw water line corridor to the Yanceyville WTP.
