must comply with the requirements set forth in 15A NCAC 04B .0124 Design Standards
in Sensitive Watersheds.
6. Sediment and erosion control measures shall not be placed in wetlands or waters. Exceptions
to this condition require application submittal to and written approval by the Division. If
placement of sediment and erosion control devices in wetlands and waters is unavoidable,
then design and placement of temporary erosion control measures shall not be conducted in a
manner that may result in dis- equilibrium of wetlands, stream beds, or banks, adjacent to or
upstream and downstream of the above structures. All sediment and erosion control devices
shall be removed and the natural grade restored within two (2) months of the date that the
Division of Energy, Mineral and Land Resources (DEMLR) or locally delegated program has
released the specific area within the project.
7. Any final construction plans for this project must include or reference the application and
plans approved by the Division under this authorization letter and certification. It shall be
the responsibility of the permitee to review all construction drawings with the approved
permit drawings to determine that the drawings are consistent. Documentation via letter or
e -mail must be provided to the Division prior to the start of construction confirming that the
construction drawings are consistent with the permitted drawings. If the drawings are not
consistent, the applicant is required to notify the Division, c/o Wilmington Regional Office and
address the inconsistencies prior to working in wetlands.

8. Pre - Construction Meetin
The permitee shall notify the Division in writing prior to the beginning of the work authorized
under this certification. A pre - construction meeting must be held with the DWR prior to the
start of the project so that the contractors and /or agents fully understand the conditions
associated with this certification,
9. NC DOT Sensitive Watershed Erosion and Sediment Control Practices
Sediment and erosion control measures shall adhere to the design standards for sensitive
watersheds [15A NCAC 4B .0124] throughout the life of this project. See NCDOT publication,
Best Management Practices for the Protection of Surface Waters (March 1997).
10. All mechanized equipment will be regularly inspected and maintained to prevent
contamination of waters and wetlands from hydrocarbons or other potential toxic chemicals.
In the event of a hydrocarbon or chemical spill, the permitee /contractor shall immediately
contact the Division of Water Resources, between the hours of 8 am to 5 pm at the
Wilmington regional office at 910.796.7215 or Steve Lewis at 919.807.6308 and after hours
and on weekends call the USCG National Response,
11. Culvert Installation
All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP
measures from the most current version of NCDOT Construction and Maintenance Activities
manual (http: / /www.ncdot.org/ doh/ operations /BMP_ manual /download /BMP_Manual.pdf),
such as sandbags, rock berms, cofferdams and other diversion structures, shall be used to
prevent excavation in flowing water.
Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered. Existing stream dimensions (including the cross section dimensions,
pattern, and longitudinal profile) must be maintained above and below locations of each
culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as
to prevent head cutting of the streams. If any of the existing pipes are or become perched, the
appropriate stream grade shall be re- established or, if the pipes are installed in a perched
manner, the pipes shall be removed and re- installed correctly.
All authorized culverts and other structures in waters, streams, and wetlands must be placed
below the elevation of the streambed by one foot for all culverts with a diameter greater than
48 inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48
inches, to allow low flow passage of water and aquatic life. Design and placement of culverts
and other structures including temporary erosion control measures shall not be conducted in a
manner that may result in dis- equilibrium of wetlands or streambeds or banks, adjacent to or
upstream and downstream of the above structures.
The applicant is required to provide evidence that the equilibrium shall be maintained if
requested in writing by DWR. Culverts shall be placed so that the opening(s) match the

US Marine Corps Camp Lejeune
DWR Permit # 12 -0270 v4
April 23, 2014
Page 7 of 9
natural stream channel wherever possible. Bank -full flows (or less) shall be accommodated
through maintenance of the existing bank -full channel. Additional culverts shall be allowed
only to receive flows exceeding bank -full. The low flow pipes should be aligned with the
deepest part of the stream channel, so that flow is maintained during low flow conditions.
Field adjustments of the culvert placements may be necessary to correctly install the culverts.
The establishment of native, woody vegetation and other soft stream bank stabilization
techniques must be used where practicable instead of rip rap or other bank hardening
methods. If rip -rap is necessary, it shall not be placed in the stream bed, unless specifically
approved by the Division of Water Resources. All approved rip -rap shall be appropriately
keyed in and only placed in wetland and stream areas that have permitted impacts.
12. If concrete is used during the construction, then all necessary measures shall be taken to
prevent direct contact between uncured or curing concrete and waters of the state. Water
that inadvertently contacts uncured concrete shall not be discharged to waters of the state
due to the potential for elevated pH and possible aquatic life /fish kills.
13. Temporary Fills /Impacts
All temporary fills to wetlands, must be installed with geotextile underneath and removed in
their entirety upon completion of that portion of the project that the impact occurred. All
temporary fill or other impacts shall be removed /restored and the impacted area returned to
the original grade after construction is complete or within 2 months of the phase of the project
the impact occurred, whichever is sooner. The various sites shall be stabilized with natural
woody vegetation and restored to prevent erosion. If the temporary impacts are not
completely removed or restored as described above within the specified time above,
additional written approval from this Office must be obtained to modify this condition.
14. The restored wetland areas will need to be monitored quarterly for at least two years for
indications of instability, erosion, sloughing, plants not surviving with photo documentation
and any remediation that may be necessary. The monitoring may be extended up to another 3
years, if the restoration sites have not adequately recovered.
15. A one -time application of fertilizer to re- establish vegetation is allowed in disturbed areas
including riparian buffers, but is restricted to no closer than 10 feet from top of bank of
streams. Any fertilizer application must comply with all other Federal, State and Local
regulations.
16. This Certification does not relieve the applicant of the responsibility to obtain all other
required Federal, State, or Local approvals.

Dear Mr. Shaver,
Your last official correspondence regarding the above - referenced project (dated 29 November 2012) provided
the applicant with a modification to proposed work. During the permit process we segregated the project
elements into phases, based on construction and planning schedules (Phases I, II, and III), and were ultimately
permitted to impact up to 1.84 acres of wetlands regulated by DA under CWA Section 404 (and an additional
0.014 ac regulated by NCDINR under Section 401). For the Phase III portion only, the applicant was
permitted to permanently fill 0.45 acre (both under Section 404 and 401 regulatory authorities). Those impacts
were to be mitigated via purchase of credits equal to 0.45 acre. These impacts were listed in table format in our
letter to USACE dated 20 November 2012, the relevant portion of which is shown below:
Permitted per manent and emporary impacts November 2012)
To assist in your review the applicant's plans for Phase 111, we stated in our correspondence dated 4 October
2012 the following:
"Perimeter Road near Wetland I (i.e., "i ") is proposed for realignment in accordance with UFC 3 -260-
01 (i.e., 500 feet clear distance +7:1 -foot allowance for a perimeter fence), which results in impacts to
Wetland I. Because a future project phase (to be completed between approximately 2014 and 2016) will
extend the western runway /over -run to the southwest (to address the airfield operational design
considerations in the NATOPS Flight Manual for MV -22s and also to fulfill UFC 3- 260 -01 requirement
for 1,000 -ft over -runs on all Navy and Marine Corps runways), the proposed Perimeter Road will need
to be realigned again in a few years to run parallel to the future runway /over -run, heading farther to the
southwest before turning to the northwest around the end of the over - run.... In the interim, the roadway
will be temporarily configured to balance aviation safety and wetland protection; the UFC clear distance
is observed for as much of the roadway as possible, but the corner of Perimeter Road near impacts Wi -1

To assist in your review the applicant's plans for Phase 111, we stated in our correspondence dated 4 October
2012 the following:
"Perimeter Road near Wetland I (i.e., "i ") is proposed for realignment in accordance with UFC 3 -260-
01 (i.e., 500 feet clear distance +7:1 -foot allowance for a perimeter fence), which results in impacts to
Wetland I. Because a future project phase (to be completed between approximately 2014 and 2016) will
extend the western runway /over -run to the southwest (to address the airfield operational design
considerations in the NATOPS Flight Manual for MV -22s and also to fulfill UFC 3- 260 -01 requirement
for 1,000 -ft over -runs on all Navy and Marine Corps runways), the proposed Perimeter Road will need
to be realigned again in a few years to run parallel to the future runway /over -run, heading farther to the
southwest before turning to the northwest around the end of the over - run.... In the interim, the roadway
will be temporarily configured to balance aviation safety and wetland protection; the UFC clear distance
is observed for as much of the roadway as possible, but the corner of Perimeter Road near impacts Wi -1

and Wi -2 (see Figure 8) will not involve a 90- degree turn, but instead a graded turn. The sharper- angle-
turn alternative would have had approximately 100% more impacts to wetlands due to installing the
necessary grading along two road segments that together are longer (and closer to the wetland) than the
proposed single reach. To achieve this reduction of impacts, a temporary exemption from the UFC was
allowed, but just for the turn /corner area. This will allow for at least a temporary preservation of
approximately 0.75 acre of wetland functions for the habitat area that would have been impacted by a
90- degree corner positioned 570 feet from the existing over -run. The combined wetland impacts for
Phase III have been minimized from the original plan by 0.69 acres and further reductions are not
practicable or possible given engineering and aviation /transportation safety concerns."
As a follow -up to the above, we indicated in subsequent correspondence the following from our letter dated 20
November 2012:
"At this point in time, only the conceptual framework for such future work is available, as discussed in
our 4 October 2012 letter. Detailed design and engineering work for that future work is not currently
under contract by the applicant, and that would have to be completed (along with any future permit
modification) to allow for the runway extension to be constructed. In the interim, we continue to support
acquiring permits to construct the re- aligned roadway as specified in our 4 October letter, as that will
provide additional safety as well as minimize wetland impacts."
In November 2013, the applicant was able to complete detailed engineering for the Phase III impact areas
referenced above (the portion indicated as being ready for construction between 2014 and 2016). In
preparation for extension of the over -run for Runway 05/23 (the western runway on the airfield) to the
southwest (necessary pursuant to the NATOPS Flight Manual for MV -22s and also to fulfill UFC 3- 260 -01),
the applicant is now requesting a permit modification to accommodate the re- location of the perimeter road to
the south.
As indicated above, the applicant was able to be granted a temporary exemption from compliance with UFC 3-
260-01 specifically regarding (1) the requirement of 500 feet clear distance (laterally from the centerline of the
runway) in addition to the 7:1 -foot allowance for a perimeter fence and (2) 1,000 feet clear distance (from the
end of the runway to the southwest) for all Navy and Marine Corps runways, and was therefore able to plan for
only a slight impact to Wetland "I" until it was absolutely necessary to be in complete compliance with the
UFC. At this time, it is now necessary to affect full compliance with federal aviation safety regulations.
Avoidance and Minimization, Given the above requirements, the applicant's engineer has repositioned the
corner /vertex of Perimeter Road approximately 200 feet to the south, while continuing to minimize impact to
wetlands the maximum extent practicable. To that effect, the road is proposed for placement as close to the
runway as possible, and sheet pile walls are proposed along the road surface boundary (at /near the corner)
where typical grading would have impacted an additional approximate 6,000 square feet (40 feet wide slope
extending approximately 150 feet along the road) to the south and 9,600 square feet (40 feet wide slope
extending approximately 240 along the road) to the north. The use of the walls will result in minimizing
impacts by 0.46 acre (see related cross - sections on revised Figures 9 and 10). Furthermore, the applicant
proposes to maintain the hydrological connection to wetland habitats in the central portion of the impact area,
just north of the corner. This will prevent impacts to an additional 0.2 -acre wetland area. Therefore, in
summary, the applicant has minimized impacts by approximately 0.66 acre. Where possible, adjacent to
permanent wetland impact areas, the applicant will re -grade and restore certain wetland areas following
construction. These temporary wetland impact areas will recover, to once again perform most wetland
functions.

Alternatives. In addition to the no action alternative, three others could be considered. They include (1)
positioning Perimeter Road to the north, outside of the wetland area, (2) positioning Perimeter Road farther to
the south of the currently proposed alignment, and (3) positioning Perimeter Road as shown in revised Figure 8
(the preferred alternative). Because the no action alternative and alternative "1" above would not result in
compliance with air safety regulation, they should be excluded from further consideration. Alternative "2"
above is not preferred as it would involve additional impacts to wetlands and would prove more costly than the
preferred alternative. Therefore, the currently proposed alignment (alternative "3") is the only alternative that
supports the project objectives (safe transit around the air field) and comprises wetland impacts that have been
minimized as much as practicable,
Unavoidable Impacts. Unavoidable impacts due to the relocation of Perimeter Road summarized below, in
comparison to the impacts as previously predicted. Formerly anticipated permanent impacts were 0.45 acre;
currently, the applicant anticipates approximately 1.34 acres of jurisdictional wetland impacts. In addition, the
applicant anticipates that approximately�361 linear: feet of intermittent stream /ditch ( "R05" on the federal .I.D.)
contained within the limits of the jurisdictional wetland will be temporarily impacted (due to fence'
