Response to USACE Request for Additional Information
Per the email of 7/21/20, the following provides each comment/question with a response (in bold
italics) to each. Also attached are
1) Revised Impact Tables
2) Revised Permit Impact Depictions
3) Response to NMFS questions under the Section 7 Consultation.
USACE Comments:
1) It is unclear if all the permanent wetland conversion impacts are addressed. It appears that in
several locations that the new sewer line will be installed within forested wetlands that are
within the existing easement but are currently not maintained and would result in permanent
wetland conversion?
a. In order to assist with the review please depict the proposed permanently maintained
corridor.
The attached revised impact sheets have been developed using current tree -line survey
and the engineering design files to depict the permanent maintained corridor in
forested wetlands, temporary wetland impacts in forested and non forested areas,
and permanent (no loss) stream impacts.
b. If additional conversion impacts do occur please update the PCN and exhibits
accordingly.
Impacts have been updated in the attached revised stream and wetland impact tables.
c. In order to assist with the review please add labels showing the impact numbers on the
impact exhibits.
Impact labels are on the attached revised impact sheets.
2) Per Regional condition 4.1.11 use of rip -rap or any other engineered structures to stabilize a
stream bed should be avoided to the maximum extent practicable. If riprap stabilization is
needed, it should be placed only on the stream banks, or, if it is necessary to be placed in the
stream bed, the finished top elevation of the riprap should not exceed that of the original
stream bed.
a. Stream impacts listed as temporary for bank stabilization appear to involve introduction
of riprap stone within the stream channel and would be considered a permanent
impact?
All stream impacts are shown as permanent — no loss due to the placement of riprap
below the bed elevation of the stream.

b. Can you provide an explanation for why riprap is necessary for the proposed impacts?
Black & Veatch, the project engineering firm, has reviewed the proposed stream
impacts and stream crossing designs. Due to the velocity of the streams, riprap
placement in the stream bed is required. The position of this sewer line adjacent to
the Neuse River causes the crossings to be at the lower end of the streams where the
channels are more incised and discharging at higher velocity into the river. Converting
these crossing to more natural stream banks without addressing upstream/watershed
controls would not lead to long term stability and may increase the amount of
maintenance needed (and therefore temporary disturbances) within the streams.
c. Will the proposed riprap be installed as to not exceed that of the original stream bed?
Yes — please see the engineering details within the construction plan set that show a
cross section of a typical stream crossing, with riprap at the bed elevation.
3) Section G. 5i. of the PCN is checked "Yes" that the project will involve blasting, and/or other
percussive activities that will be conducted by machines, such as jackhammers, mechanized pile
drivers, etc.
a. Can you provide details to include type of percussive activity, purpose, duration, and the
location of this activity on the property?
Preliminary geotechnical boring locations along the line indicate that percussive
activities will be required, but the exact location and extent will not be accurately
determined until construction begins.
The project is located within the Northern Long -Eared Bat range but Wake County is
not shown on the USFWS Raleigh Office website as a county where this species is
known to currently occur. In addition, NC Natural Heritage Program records do not
indicate known occurrences within the specified % mile radius of the project.
4) In order to verify compliance with section 7(a)(2) of the Endangered Species Act please address
the below questions. Note: the Permit area includes the waters that will be directly affected by
the proposed work and the uplands directly affected as a result of authorizing the work.
a. Does the permit area contain suitable habitat for Michaux's sumac?
Some areas of potential habitat exist along the corridor where maintenance regimes
allow for this species to survive. The project corridor was surveyed during the 2020
recommended window for this species and none were observed.
b. Does the permit area contain suitable habitat for RCW?
No. Limited pine stands are present along the corridor and those were of insufficient
age or dominated by hardwood species. No known occurrences of RCW are recorded
within the project vicinity.
c. Note: Additional information may be requested during consultation with USFWS.

Understood.
5) Will the existing pipe under the Neuse River be removed? If so will this be done using the same
process as installation? Will it be done at the same time?
The existing pipe under the Neuse river will be retained, but will not be in service. Having this
pipe in place allows for temporary bypass of the proposed sewer line in the event future
maintenance is needed, without disturbing the river.
6) It appears as though there is permanent impacts at the Neuse River crossing?
a. It appears that permanent riprap is to be installed on the stream banks below the
OHWM resulting in permanent impacts.
i. Can you provide an explanation for why riprap is necessary for the proposed
impact?
Velocities in the river are extremely high at times, resulting in the need to
stabilize the riverbed at the crossing in order to prevent disturbance to the bed
and protect the proposed sewer pipe. Class 1 and 2 riprap is proposed to
address this issue.
b. It appears that the concrete pipe encasement meets the existing stream bed elevation
of the Neuse River at one location?
i. Can the depth/slope of the pipe can be altered so that the natural stream bed
material could be placed to match the preexisting conditions?
No — the proposed sewer line is designed at the absolute minimum grade to
connect to existing infrastructure while allowing the sewer line to flow and
prevent blockages. This is also why the river crossing is proposed for open -cut
as subsurface technologies would not guarantee that the exact grade will be
maintained.
ii. As proposed the concrete encasement may be a permanent stream channel
impact.
A small permanent impact of 20 square feet of concrete encasement will be
exposed in the river bed, but is too small to depict on the impact maps.
7) The location of the Neuse River crossing is located approximately 5000 linear feet upstream of
NOAAs critical habitat designation and NCWRCs Anadromous Fish Spawning Inland Waters Area.
The extent of these areas were limited to the Neuse downstream of the Milburnie Dam, which
since has been removed. It appears that in order to verify compliance with General Condition 3
& 18 and Regional Conditions 1.1 & 1.3 coordination/consultation with NOAA and NCWRC will
be necessary.
a. I have attached the Section 7 checklist which will need to be filled out in order to consult
with NOAA.
Acknowledged — Section 7 Consultation with NMFS is ongoing and responses to their
request for information is also attached.

Response to NMFS Request for Additional Information
1. The copies of some of the plan drawing pages are very low resolution and are not legible even
when zoomed in on screen. Please submit legible copies of pages G (C?)-02, G (C?)-03, D-04, D-
05, and D-06.
Higher resolution plans are available at the link provided via email.
2. The project description mentions that coffer dams will be installed to dewater portions of the
river during construction. Please provide the details on the construction and placement
methods for these temporary structures (number and size of piles (if used) and how they will be
driven into/ secured to the substrate for placement).
The engineer doesn't typically dictate the exact method or type of coffer dam in contracts, but
would expect that the Porta-dam system, or similar approach, may be used. This would not
require piles. These are metal frames with a waterproof membrane (like a tarp) pulled over
the frame. Additional information is available at the following link:
Temporary Cofferdams, Flood Protection & Water Storage (portadam.com)
3. If the exact number of piles is not known, please estimate the number of piles to be driven per
day (if used).
See response to #2, if piles are used it is unknown how many may be installed per day, but
none are anticipated.
4. The project description also mentions excavation of the substrate for placement of the pipes
crossing the river, but the Section 7 checklist says there will be no dredging. Please estimate the
amount (volume) of material that will be excavated.
The checklist was filled out interpreting "dredging" differently from "excavation" while
notifying NMFS of excavation that will occur. All volume of material excavated will essentially
be equal to volume of the pipe and the concrete around the pipe. Excavation within the river
would be approximately 950 cubic yards. All excavation is temporary, with river bottom
elevations to be restored to pre -construction elevations.
5. If spoils will be stored temporarily on site, please describe how/ where it will be stored prior to
replacement.

Spoils will be stored in the construction easement away from the river prior to being hauled
offsite for disposal. Stockpile areas will be secured with erosion control measures (silt fence
etc.) to prevent sedimentation of adjacent waters during the storage period.
6. Please include how any excess spoils will be disposed of.
Spoils will be disposed of offsite in upland areas with adequate stabilization.
