Robb and Daniel,
I hope you all are doing well and have not been impacted much by the recent storms.
I am touching base on the environmental permitting packages that were submitted in August for the P1043 Water
Treatment Plant at MCB Camp Lejeune. We received and have addressed the comments provided by Brad in the original
email of this thread with the following revisions:
-Adding a cross section depicting the sag in the power line upgrade crossing Wallace Creek -Editing language to clarify
trenching vs HDD locations
We are waiting on the final NPDES permit and expect to receive it shortly. At that time we will resubmit the revised
packages. Please let me know the following:
-Are there any further comments on the draft packages?
-Will the complete package need to be resubmitted once the final NPDES permit is available? If so, is a hard copy
required or will an electronic version be sufficient?
-What is the anticipated turn -around time upon receipt to issue the permit?
Thank you,
Verd Anna

Hi Brad -
Thank you again for your time reviewing the application for the Nationwide 7 and 12 for the Water Treatment Plant.
The base has inquired again if the permit can be issued with only the draft NPDES permit in hand. Your statement below
confirms the need for the final NPDES permit. We will pass that confirmation along to them again today.
Regards,
Jaime Robinson

Jessi,
The Corps has received your application for Nationwide 7 and 12 for the subject project. We have reviewed the
document and determined it to be incomplete and or require clarification. Below is an itemized list:
- in order to utilize NW 7 there must be a finalized NPDES permit issued under the 402 program. The current
authorization is a draft still awaiting another
public notice period before a final decision is made. Please resubmit the request once the final permit from the State has
been issued.
- whereas the waterline does not necessarily require prior notice under NW
12
the power line does as it crosses Wallace Creek, a navigable and tidally influenced water, thus Section 10. The
application states on the nav chart that the power line will be set 20' above the water which is appropriate but
please provide a simple cross section drawing of the crossing that may be referred to when the verification is issued.
Please depict the sag expected in the line as the low spot over the Section 10 water.
- the impact summary table within the PCN states the line along the trail will be trenched but section 133e and figure 4
states that any delineated wetland will be crossed via directional drill. I don't think that was intentional therefore please
correct the language in each of these sections.
Once you have the final authorization from the State please resubmit the PCN
with the requested changes.
Thanks and if you have any questions please don't hesitate to give me a call,
Brad

The outfall discharge pipeline will be installed using conventional trenching methods and equipment, primarily excavators.
Soils will be inverted with all outfall line installation work, to place organics back in the trench last.
Wetlands within the maintained right-of-way will be restored to preexisting conditions.
Crossings under currently undisturbed, forested, wetland/stream areas, and primary roadways will be accomplished using horizontal directional drilling (HDD) using a conventional HDD
rig and appurtenant equipment.

133d. Explain the purpose of the proposed project: The United States Marine Corps proposes to
construct a new, permanent 8 MGD water treatment facility will be constructed along Holcomb
Boulevard near Wallace Creek at Marine Corps Base Camp Lejeune. The discharge pipe outfall will be
located in the mouth of Wallace Creek, southwest of Marston Pavillion. A project map and outfall map
are included as Attachments 9 and 10, respectively. These permits specifically relate to the
concentrate/backwash waste discharge outfall line to Wallace Creek at its confluence with Morgan Bay.
133e. Describe the overall project in detail, including the type of equipment to be used:
This project includes approximately 13,500 linear feet of outfall discharge pipeline in an existing utility
easement with a diffuser approximately 91 -feet long located near the mouth of Wallace Creek in the
New River, and 21,500 linear feet of upgraded power line and poles in another existing utility easement
as shown in Attachment 9.
The water treatment plant will be constructed using conventional construction methods and heavy
equipment to include, but will not be limited to; graders, excavators, dump trucks, pile drivers, cranes,
concrete pumpers, and soil compactors.
In upland areas and areas where wetlands with herbaceous vegetation are present within the currently
maintained trail and utility right-of-way, the outfall discharge pipeline will be installed using
conventional trenching methods and equipment, primarily excavators. Crossings under currently
undisturbed, forested, wetland/stream areas, and primary roadways will be accomplished using
horizontal directional drilling (HDD) using a conventional HDD rig and appurtenant equipment. The
portion of the outfall pipeline located beneath Morgan Bay will be installed using barge -mounted HDD.
(Attachment 12) Design intent for this portion of the Work is to first advance a temporary steel
conductor casing from the barge, which will extend from below the mudline to above the water line that
will contain and conduct drilling fluid and spoils to a containment tank located aboard the barge. The
directional drill stem will then be advanced through the steel conductor casing on the water -side, under
the seabed, and then to the land -side exit pit located beyond the limit of the delineated wetlands. The
outfall piping will then be pulled back toward the barge beneath the seabed and up through the
conductor casing. The casing will then be removed.
Design drawings for the diffuser are included as DIAGRAM 0 F DATUM PLANE
Attachments 3 through 5, and a diffuser location map is nor T1-
included
oincluded as Attachment 11. The diffuser assembly is
approximately 91 feet Ion and will be installed at a depth �`���`"� �`�" " ��� '�°
pp Y g
of approximately 5 feet below mean sea level (MSL). This N1 F.,N -1 „ L I � ,
area is tidally influenced, and the diffuser assembly itself
will remain submerged according to the datum diagramr,-
shown at right. The location will be visible above the
water surface, with wood piles reaching 4 feet above MSL f ,IFAS -c:�:� %r,;ATrr \,_;`;
and marked with appropriate reflectors and signage. The
mean higher high water mark (MHHW) is located 0.2 feet ► r F" L` `F - "`
above MSL, per the datum plane diagram applicable for
the diffuser location, well below the pile design height of 4 feet above MSL.
The Construction Contractor will determine the means and methods required for installation of the
outfall diffuser assembly. It is anticipated that the assembly will either be installed using divers or "in the
dry' through the installation of a temporary coffer dam. Best management practices including those
general conditions listed in NWP 7 will be used to limit environmental impacts during construction.
The power line that will supply power to the water treatment plant, located between Substation 1 and
Substation 2, will also be upgraded as part of the project. This will be done in accordance with Regional
Condition 4.6.7. The power poles will be replaced in-kind and wetland mats and/or low ground pressure
equipment will be used to access wetland areas. All work will be conducted within the existing right-of-
way, and no clearing will be required. Best management practices will be implemented, existing
topography will be maintained, and the wetland areas will be restored to preexisting conditions using a
wetland seed mix. (Attachment 13)
FSd. What data sources did you use to determine whether your site would impact Endangered Species
or Designated Critical Habitat? Two Federally protected species that may occur in Wallace Creek where
the diffuser structure will be installed include Atlantic sturgeon (Carolina distinct population segment),
listed as Endangered, and West Indian manatee, listed as Threatened. Both species have an element
occurrence in the project area in the North Carolina Natural Heritage Program Natural Heritage Element
Occurrences April 2017 data. The New River was not included as historic or current spawning habitat for
Atlantic sturgeon in the Status Review of Atlantic Sturgeon (NOAA, updated July 27, 2007). The New
River is also not included in the critical habitat for Atlantic sturgeon designated in 2017 by NOAA
Fisheries. Manatees are a transient species, and some West Indian manatees migrate from Florida north
into the Carolinas in the summer to adapt to seasonal water temperatures.
The installation and operation of the outfall and diffuser structure is unlikely to adversely affect these
marine species, the project would be consistent with policies designed to protect these animals
including their habitat, such as following the guidelines for avoiding impacts to the West Indian
Manatee. The waters at the outfall structure are designated as special secondary nursery areas
(Attachment 15), which will be protected by the specifications in the NPDES permit.
