RE: Request for Additional Information: City of Eden Waterline to SoVA Mega Park,
Rockingham Co.
SAW -2o18-02188
Dear Mr. Bailey:
Per the request for additional information received December 20, 2018 via email, provided
below are responses and updated documents:
1. Project plans require additional details:
a. Currently wetland areas are not clearly visible on the plan sheets. Add all wetland
boundaries to the plans and label them according to the delineation documentation
provided by Dewberry on 8/24/2018. I recommend that a different color be used on
the plan sheets for wetland lines (such as green?). Show and label the wetland
boundaries on the profile drawings as well;
Response: Wetland boundaries are shown in color and labeled on
updated plans.
b. Clearly label all streams on the plan sheets according to the delineation
documentation provided by Dewberry on 8/24/2018. I recommend that a different
color be used on the plan sheets for stream lines (such as blue?). Show and label the
streams on the profile drawings as well;
Response: Streams are shown in blue and labeled on the updated plans.
c. Currently there is no way to match up itemized impacts listed in the PCN with the
plans. As such, add Impact Site labels to the plans, and add corresponding labels to
Section D. of the PCN for clarity purposes:
Impact Site 1: Wetlands WD and WE
Impact Site 2: Stream SH;
Impact Site 3: Wetlands WC (2 areas);
Impact Site 4: Streams SF and SG, Wetland WB;
Impact Site 5: Stream SE;
Impact Site 6: Streams SC and SD;
Impact Site 7: Streams SA and SB, Wetland WA;

Mr. David E. Bailey, PWS

Page 2 of 7
Response: Impact site labels were added to the updated plans and the
Impact Table was revised to reflect site labels. Currently Impact Sites
are labeled as:
Impact Site 1: Wetland WD
Impact Site 2: Stream SH
Impact Site 3: Cascade Creek (Stream SF and SB)
Impact Site 4: Wetland WB
Impact Site 5: Stream SE
Impact Site 6: Stream SD
Impact Site 7: Stream SC
Impact Site 8; Stream SB and SA
d. Specify whether the utility corridor would include a permanent maintenance
easement where vegetation would be maintained in an herbaceous state. If so,
include zoomed -in details of each stream and/or wetland crossing showing the
footprint of the permanent maintenance and temporary construction corridors. Such
details must also show the extent of temporary impacts (streams and wetlands) and
extent of permanent maintenance impacts through wetland areas. Further, for each
applicable crossing, quantify the acreage of wetlands proposed to be converted from
forested wetlands and permanently maintained in an herbaceous state and add those
as separate impacts in Section D of the PCN;
Response: The wetlands and streams are within NCDOT right-of-way
and maintained by that agency. Any current regular maintenance by
NCDOT will be the same going forward.
Zoomed in details are shown for each impact for a clearer view. All
construction within wetlands and streams will be a temporary impact,
with the exception of rip rap stabilization on the stream banks, which
will be permanent. The wetlands in their existing state are not forested
within the NCDOT right-of-way.
2. Project plans indicate that stream crossings include discharging rip rap. If so, please
confirm (including via profile drawings) that any rip rap placed below the ordinary high
water mark will be placed such that the top of the rip rap will be no higher than the existing
stream bed elevation (see NWP 12 Regional Condition 4.1.11). Note that the "Rip -Rap
Placement Detail" on Sheet C22 does not appear to comply with this Regional Condition.
Also, since discharged rip rap would not be removed, the lengths of stream subject to rip rap
discharge must be added to the PCN as permanent impacts;
Response: Referring to Sections 4.1.11 and 3.5.2 of the NWP 12 Regional
Condition, riprap will be pushed or keyed into the bank of the waterbody, no
higher than existing stream bed elevation. This method is shown on the rip -rap
placement detail. Please advise of any outlying concern.

3. Given the time past from the date of the USFWS Section 7 self -certification letter, as well as
the known occurrences of several aquatic species in Cascade Creek and the Dan River, we
have initiated informal consultation with the USFWS. Please note that the Corps cannot
verify the use of a NWP until Section 7 consultation is complete;
Response: The USFWS letter sent on 12/20/2019 identified species of concern
as the Roanoke Logperch, James Spinymussel, Atlantic Pigtoe, and Smooth
Coneflower. A Smooth Coneflower survey will be performed in May.A revised
Self -Certification package for the project will be re -submitted to USACE as soon
as possible.
Further information regarding the aquatic species is discussed in the next
comment.
4. Given that occurrences of Roanoke logperch are known in Cascade Creek, and occurrences of
James spinymussel are known just downstream in the Dan River, avoidance of impacts to
Cascade Creek via HDD or jack and bore methods seem reasonable. However, the plans note
an alternative trenching method through Cascade Creek and the PCN accounts for
temporary impacts to Cascade Creek due to trenching. Please clear up this discrepancy in the
plans and PCN, such that the project would be compliant with NWP 12 Regional Condition
4.1.1. If the Cascade Creek crossing would be installed via HDD, remove this impact from
Section D of the PCN and add a note on this page clearly indicating that the impact would be
avoided in this manner;
Response: The impacts in the PCN consider that Cascade Creek is open cut
(trench installation) — thus indicating maximum impact possible. The contract
documents allow for the contractor to choose either directional bore or open
cut methods. However, we do not want to strictly limit the crossing to only
directional drilling or jack and bore methods due the following concerns:
Directional Drill — Though directional drilling is becoming very
conventional for smaller utilities, directional drilling and installation of a
large 20" waterline is highly specialized, will require greater depth into
consolidated material/rock (due to relatively shallow saturated overlying
soil conditions), and require a bore of approximately l000 LF due to setup
conditions at this site. Based on our experience, approximately two years
ago in installing a 16" sewer forcemain on the opposite side of the road to
cross Cascade Creek, contractors bidding this work were only able to get one
price from a subcontractor that had the capability to directional bore the
large 16" forcemain. Price for this work was more than three times the cost
of open cut; consequently we had to delay the project and obtain approval to
open cut and install the sewer forcemain via open cut. It is an
unreasonable expectation of the City of Eden taxpayers to take on this
".g.-:1,Dewberry�a

Mr. David E. Bailey, PWS

additional cost and risk to the project when reasonable mitigation measures
appear to be available to adequately safeguard the environment.
Jack and Bore — In order to dig the bore pits deep enough to execute the
bore of Cascade Creek, an extensive amount of shoring will be required to
retain the road embankment. The groundwater table is also very high in
this area, which will also require specialized dewatering methods in the
bore pit area, in addition to the shoring. These are sophisticated and
higher -risk construction methods, which also pose a safety risk to workers.
We do not recommend jack and bore for installation under Cascade Creek.
If open cut is utilized, to minimize potential impacts to listed threatened or
endangered aquatic species, we propose to restrict work so that work will only
occur outside the spawning season of each of the listed species. Construction
details, related mitigation methods, as well as restoration indicated on sheet C-
22 will be strictly adhered to. Full time inspection will be provided to insure
compliance with mitigation measures. Final restoration of grade to original,
and restoration of vegetation per planting schedules on C-22 will be performed.
5. Provide a plan including any pertinent detail sections for typical wetland impacts via
trenching. Such plans should include dewatering methods, lengths of time that trenches will
be open in wetlands, and confirmation that the top 6 to 12 inches of the trench will be
backfilled with topsoil from the trench. Per NWP 12 Regional Condition 4.1.9, provide a
specific wetland restoration plan including how grade and contour will be re-established,
anti -compaction measures in soils subject to construction traffic and matting, stabilization
methods, and seeding/planting lists and specifications. Be sure to specify wetland
restoration differences in temporary and permanent easement areas. Such details should be
provided as an addendum that can be referenced in permit Special Conditions;
Response: C22 serves as the Wetland and Stream Impacts detail sheet and
includes temporary and permanent seeding mixtures.
6. Plan sheet -specific comments:
a. Sheet C5: Wetland lines do not appear on the plan sheet (should be Wetlands WD
and WE, per comment 1)a above. The footprint of wetland areas proposed for impact
(permanent maintenance as well as temporary construction corridors) should be
clearly shown on a zoom -in of the crossing (should be labeled "Impact Site 1" per
comment 1)c. above. The sheet references "Provide Stream Restoration per Details";
however, this area includes wetlands rather than streams, and the plan sheet should
reference a Wetland Restoration plan (see comment 5 above);
Response: Wetland lines and labels added, zoom -in view of impact
added, and temporary construction corridor is shown. The permanent
maintenance easement is the NCDOT right-of-way. Refer to the profile

view of the stream bank restoration detail area — this is to protect the
bank where the pipe goes under the existing stormwater culvert. This
does not impact the wetland, and the note simply refers to the detail by
which the rip rap shall be installed.
b. Sheet C6: Clearly show and label Stream SH per comment 1)b above. The footprint of
the stream proposed for impact should be clearly shown on a zoom -in of the crossing
(should be labeled "Impact Site 2" per comment 1)c. above);
Response: Stream label added, and zoom -in view of impact added.
c. Sheet C7: Wetland lines do not appear on the plan sheet (should be Wetland WC [2
segments], per comment 1)a above). The footprint of wetland areas proposed for
impact (permanent maintenance as well as temporary construction corridors) should
be clearly shown on a zoom -in of the crossing (should be labeled "Impact Site 3" per
comment 1)c. above). The sheet should also reference a Wetland Restoration plan
(see comment 5 above);
Response: Wetlands are located outside the NCDOT right-of-way and
construction is limited to within the right-of-way. Thus, no impact to the
wetlands. Wetland lines have been illustrated on the plan sheet.
d. Sheet C8: Clearly show and label Streams SF and SG per comment 1)b above. If
applicable, the footprint of the stream proposed for impact should be clearly shown
on a zoom -in of the crossing. The plan sheet shows both an HDD plan and an
"Alternative Open -Cut Cascade" option. Please clear up this discrepancy (per
comment 4 above). Wetland lines do not clearly appear on the plan sheet (should be
Wetland WB, per comment 1)a above). The footprint of wetland areas proposed for
impact (permanent maintenance as well as temporary construction corridors) should
be clearly shown on a zoom -in of the crossing. The sheet should also reference a
Wetland Restoration plan (see comment 5 above); Note that both the stream and
wetland crossing should be labeled "Impact Site 4" per comment 1)c. above;
Response: Wetland and stream lines and labels added, zoom -in view of
impact added, and reference to Wetland and Stream Impacts Details
added.
e. Sheet C1o: Clearly show and label Stream SE per comment 1)b above. The footprint
of the stream proposed for impact should be clearly shown on a zoom -in of the
crossing (should be labeled "Impact Site 5" per comment 1)c. above);
Response: Wetland lines and labels added, and zoom -in view of impact
added.

f. Sheet C14: Clearly show and label Streams SC and SD per comment 1)b above. The
plan sheet indicates that the waterline would be installed essentially within the bank
of Stream SC. As such it is reasonable to assume that the waterline would impact
Stream SC itself. Provide information to justify that impacts to Stream SC would be
avoided with the current plan, or quantify proposed impacts and add to the
plan/profile sheets and PCN. The footprint of the streams proposed for impact
should be clearly shown on a zoom -in of the crossing (should be labeled "Impact Site
6" per comment 1)c. above);
Response: Stream labels added, impacts to SC revised to account for
potential construction encroachment on fringe of stream.
g. Sheet C17: Clearly show and label Streams SA and SB per comment 1)b above. The
footprint of the streams proposed for impact should be clearly shown on a zoom -in of
the crossing. Wetland lines do not clearly appear on the plan sheet (should be
Wetland WA, per comment 1)a above). The footprint of wetland area proposed for
impact (permanent maintenance as well as temporary construction corridors) should
be clearly shown on a zoom -in of the crossing. The sheet should also reference a
Wetland Restoration plan (see comment 5 above); Note that both the streams and
wetland crossing should be labeled "Impact Site 7" per comment 1)c. above.
Response: Stream labels added, wetland lines added, zoom -in view is
shown. Wetland WA will not be impacted.

NPDES Stormwater Discharge Permit
for Construction Activities
Technical Bullentin for NCGO10000
Revised Jan. 12, 2017
What is this permit?
This is your General Stormwater Permit for Construction Activities, developed to meet federal National Pollutant Discharge Elimination
System (NPDES) requirements. It is separate and in addition to your Erosion and Sedimentation Control (E&SC) Plan.
Federal regulations adopted by the U.S. Environmental Protection Agency (EPA) and N.C. Environmental Management Commission require
an NPDES storm -water permit for your project. In North Carolina, the EPA has delegated authority to administer the NPDES program to the
Department of Environment and Natural Resources.
The E&SC plan approved by the Division of Energy, Mineral and Land (DEMUR), or a delegated local pro- gram, contains the core erosion
control requirements for your project. The NPDES Stormwater General Permit contains additional requirements related to a broader range of
water quality issues. These permits are related, but separate. Both contain conditions your project site must meet.
Are there new requirements in this permit?
This General Permit reflects changes made in the federal regulations effective Feb. 1, 2010, that regulate discharges from construction sites.
The federal regulations resulted from litigation decisions that mandated construction activities over a certain size must contain additional
measures to reduce the amount of wastes and sediment loading that reach the nation's waters.
The Department of Environment and Natural Re- sources established the Construction General Permit Technical Advisory Group to guide the
development of this NPDES permit. A drag permit was available for public review in May 2011, and the final permit be- came effective on
Aug.3,2011.
The most notable change in the new permit is a requirement that ground stabilization, such as wheat straw application, be applied within 14
days from the last land -disturbing activity. For steep slopes, that area must be stabilized within 7 days. Please see page 2 of this technical
bulletin for more details.
Do I need to submit a Noticeof Intent to have coverage under this permit?
No. Your project is covered by this permit upon approval of an adequate erosion and Sedimentation control plan that meets requirements for
surface dewatering of basins and ground stabilization timeframes.
What tloes this permit require me to do?
You should read and become familiar with the provisions of this permit. Below is a list of the major requirements, with indications where those
differ from the previous Construction Stormwater General Permit.
Erosion and Sediment Control Plan
You must implement the E&SC Plan approved for your project by DEMLR or by a delegated local program. Adherence to that E&SC Plan is
an enforceable component of this General Permit. Your E&SC plan will identify areas where the more stringent 7- and 14- day ground
stabilization requirements apply. See "Ground Stabilization Requirements" on page 2 of this bulletin.
Monitoring and Inspections
• You must keep a rain gauge on the project site.
• Dedicated demolition and other waste areas and earthen material stockpiles must be located at least 50' from stoml drains or streams
unless no alternative is feasible (new requirement).
• You must inspect all E&SC measures at least once a week and within 24 hours after any storm event greater than a half-inch (during a
24-hour period). You must take immediate corrective action for any device failure.
• You must inspect all outlets where stormwater runoff leaves the site and evaluate the effect on near -by streams or wetlands.
• Corrective action must be taken if sediment is deposited off -she or into a stream or wetland, or causes a visible increase in turbidity
(cloudiness) of any waterbody.
r (• You must keep records of these inspections and any corrective actions taken.

q
Operation and Maintenance
You must provide the operation and maintenance necessary to maintain optimal performance of slormwater controls. This means you must
take corrective action if erosion and sediment control measures are not operating properly. Operation and maintenance includes, but is not
limited to:
• Regularly cleaning out sedimentation basins.
• Stabilizing eroded banks, channels or spillway structures.
• Repairing/clearing out inlets and outlets.
• Repairing and maintaining storm drainage inlet and outlet protection.
• Repairing piping, seepage and mechanical damage.
• Repairing silt fence damage.
Reporting
The self -inspections required by this permit are an opportunity to identify impacts to nearby waters. If you observe sediment that has
deposited in a stream or wetland, you must notify the DEMLR regional office within 24 hours and provide written notice within five days (see
item #3 on page six of the General Permit).
Non-compliance and Fines
Projects that violate Stormwater Permit conditions and/or have un -authorized water quality impacts are subject to fines. Civil penalties of up
to $25,000 per day for each violation may be assessed.
Inspections
Staff from DEMUR and local pro -grams with delegated authority will perform random inspections of your project site to ensure compliance
with state and federal regulation governing construction activities. That means that your project, if found to be in violation, could potentially be
subject to enforcement action by both DEMUR and the local program. The inspections may be routine in nature or the result of a citizen
complaint.

general categories:
High-malnUm,Xa areas are mowed frequently, limed and

STEEP SLOPES
The aperomn of equipment is resected on slopes steeper
than 3:1, severely limiting Me quality of the Seedbed that can
be prepared. The soil cannot be sumclendy worked antl
amendments cannot be thoroughly intro-OmaL.
Provisions for establishment of VN,UMon on steep slopes con
be made during final grading. In comanucrlom of fill stapes,
for example, the last 46 inches might be Iefl mcmn,eck d.

chosen for Mese stapes must not require mowing or he,

applied in one operation.
Good mulching preaices IS crMcel to protect egeind erosion

product may be required to protect the slope.
SPE'U cation.
SEEDBED REQUIREMENTS
Establishment of vegetation should not be afferumul on saes
that are unsuitable due to In,pp,,pd,m soil texture (Table
6.11 a), poor drainage, wncentmted -Hand flow, or
steepness of slope until measures have been taken to coned
these problems.
To maintain a good stand of vegetation, the soli most meet
certain minimum requirements IS a O -h UnM ium. The
existing soil should have these criteria:
Enough fine -gamed (silt antl clay) material to maintain
adequate moisture antl nutrient supply (available water
capacity of at I ... t.05 inch,, of water to 1 inch of sollf.
Sufficient pore space to pemft mot p.mmotim,
S.reaela depth of sal to Provide an M.q.at. roof no.
The depth to rock or impermeable layers such as hardpans
should be 12 inches Dr mare, except on slopes steeper than
2:1 where the addition of soil is not feasible.
A favorable pH range for plant growth, usually 6.0-6.5.
Freedom from large mats, branches, stones, large cods of
earth, or rash of any kind. Clods and stones may be left on
Slopes steeper than 3:1 If they are to be hyaroo.M..
If any of the above criteria are not me[-i.e., if the PAsti,g
soil is too coarse, tlense. shallow, or aatlic to foster
vegetation -special amendments are required. The coil

DefinRion
A graveled area or pad located at points where vehicles
enter and leave a construction site.
Purpose
To provide a buffer area where vehicles can drop their
mud and sediment to avoid transporting it onto public
roads, to control erosion from surface runoff, and to help
Control dust.
CondtUM Where
Practice Applies
Wherever traffic will be leaving a construction site and
moving directly onto a public road or other paved off-site
area. Construction plans should limit traffic to properly
constructed entrances.
Design Coterie
Aggregate Size --Use 2-3 inch washed stone.
Dimensions of gravel pad --
Thickness: 6 inches minimum
Width: 12 -feat minimum or full width at all points of the
V
ehicular entrance and exit area, whichever is greater
Length: 50 -feet minimum
Location --Locate construction entrances and exits to limit
sediment from leaving the site and to provide for
maximum utility by all construction vehicles (Figure 6.G6a).
Avoid steep grades, and entrances at curves in public
roads.

Washing -If conditions at the site are such that most of
the mud and sediment are not removed by vehicles
traveling over the gravel, the tires should be washed.
Washing should be done on an area stabilized with
crushed stone that drains into a sediment trap or other
suitable disposal area. A wash rack may also be used to

PLANTING NARRATIVE
THE FIRST STEP OF THIS PLAN INVOLVES THE TEMPORARY SEEDING OF ALL DISTURBED AREAS FOR THE PURPOSE OF PROVIDING A
QUICK MEANS OF EROSION AND SEDIMENT CONTROL FOR THE ENTIRE SITE. SEE THE SECTION TITLED "SEEDING" ON THIS SHEET FOR
TEMPORARY SEEDING SPECIFICATIONS. BECAUSE THE TEMPORARY SEEDING TYPICALLY ONLY LASTS ONE SEASON, IT IS NECESSARY
TO APPLY PERMANENT SEEDING BEFORE THE END OF THE FIRST SEASON.
THE PERMANENT SEEDING PROVIDES A MORE PERMANENT VEGETATIVE LAYER OVER ALL DISTURBED AREAS FOR EROSION &
SEDIMENT CONTROL PURPOSES AND FOR THE BENEFIT OF HABITAT. REFER TO THE SECTION TITLED "SEEDING" BELOW FOR
PERMANENT SEEDING SPECIFICATIONS. THE SEED MIX SPECIFIED WAS CHOSEN TO SPECIFICALLY ADDRESS BOTH EROSION CONTROL
AND HABITAT GOALS.
SEEDING
