for the L.V. Sutton Energy Complex - Sutton Lake Dam Rearmament and
Vegetation Removal Project located at the L.V. Sutton Energy Complex in
New Hanover County, North Carolina. The U.S. Army Corps of Engineers
(USACE) issued Action ID SAW-2011-00858 for authorization of fill impacts
to jurisdictional waters on March 30, 2019 and the NC Department of
Environmental Quality, Division of Water Resources (NCDEQ-DWR) issues
an Individual 401 Water Quality Certification WQC004207 on March 20,
2020. A request is made herein for a modification of the issued USACE IP
and NCDEQ-DWR WgC004207. The modification request includes
background information, the rationale (updated purpose and need) for the
proposed action, updated Plan Viewdrawings, updated tabular data on
newwetland impacts, and compensatory mitigation.
The proposed modification to the issued USACE IP (SAW-2011-00858) and
NCDEW-DWR Certification (WQC004207) is necessary to address the
following item of concern. This item of concern must be resolved for
completion (closure) of the Sutton Lake Dam Rearmament and Vegetation
Removal Project and to assure that the authorized activities onsite for the
project are in compliance with USACE regulatory requirements. The item of
concern entails the additional placement of stone (rip -rap) within the 15-
foot zone (repair area) from the toe of the dam. The stone was placed
beyond (waterward of) the six-foot zone and was a field action that
occurred during the initial construction effort to armor the cleared zone with
geotextile fabric and rip -rap. Furthermore, the field change was based on
engineering judgement, or necessity, that additional armament would be
required in specific observed locations. This action resulted in an additional
impact of 0.493 acre to Wetland E. Furthermore, this action was completed
as based on the need to clear tree and shrub vegetation from areas of
armament within the 15-foot zone from the toe of the dam.

Ms. Homewood,
On behalf of Duke Energy, Wood Environment & Infrastructure Solutions, Inc. (Wood) previously
submitted a Joint Individual Permit (IP) Application for the L.V. Sutton Energy Complex - Sutton
Lake Dam Rearmament and Vegetation Removal Project located at the L.V. Sutton Energy
Complex in New Hanover County, North Carolina. The U.S. Army Corps of Engineers (USACE)
issued Action ID SAW-2011-00858 for authorization of fill impacts to jurisdictional waters on
March 30, 2019 and the NC Department of Environmental Quality, Division of Water Resources

2020. A request is made herein for a modification of the issued USACE IP and NCDEQ-DWR
WQC004207. The modification request includes background information, the rationale (updated
purpose and need) for the proposed action, updated Plan View drawings, updated tabular data
on new wetland impacts, and compensatory mitigation.
Background Information
The L.V. Sutton Energy Complex (plant) was a 575-megawatt coal-fired plant and three oil -
fueled combustion turbine power generators. The coal-fired plant was retired in November
2013, with demolition of the coal plant and older combustion turbines completed in 2017. The
L.V. Sutton Energy Complex is now a 625-megawatt natural gas combined -cycle plant, which
began operation in 2013. The Cape Fear River abuts the western edges of the plant property.

November 12, 2020 Dam Rearmament and Vegetation Removal Project
Page 2
On the morning of September 14, 2018, Hurricane Florence made landfall in southeastern North
Carolina. Three breaches occurred in the Sutton Lake Dam due to the hurricane. The breaches
were repaired, but the effects of the hurricane necessitated that Duke Energy increase the
structural integrity of the Sutton Lake Dam. Duke Energy desired to complete the rearmament of
the Sutton Lake Dam before subsequent hurricane(s) strike Wilmington.
Since its construction in 1972, trees and shrubbery have grown unchecked around the base of
the dam. To restore the integrity of the Sutton Lake Dam, Duke Energy proposed to remove
vegetation off the slope of the dam and a 15-foot zone from the toe of the dam. Under the
issued USACE IP, trees within the 15-foot zone were cut at the base of the tree and the root ball
left intact to minimize potential wetland impacts. The first six -feet of the 15-foot zone
(waterward from the dam toe) was permanently armored (repair area). Maintaining this six-foot
clearing would facilitate regular dam safety inspections. The remainder of the 15-foot clearing
(i.e., nine -foot working area) was temporarily impacted during construction and allowed to
return to its native state after the completion of the project.
The permitted project purpose was to clear volunteer vegetation from the dam slope and 15-
foot zone. The project purpose was based on the following needs:
• To facilitate regular dam safety inspections;
• Improve structural integrity of the Sutton Lake Dam by armoring the dam with geotextile
fabric and rip -rap to withstand future hurricane events; and
• To ensure the health and safety of citizens living downstream of the L.V. Sutton Energy
Complex.
The USACE IP application submittal package included information on alternatives analysis and a
comparison of design plans for rearmament of the Sutton Lake Dam. All action alternatives
included rip -rap and geotextile placed along the entire (3.6 miles) interior slope (cooling lake
side) of the dam for rearmament. The three plans were based on the materials used to solidify
the crest and exterior slope of the dam above the elevation of eight -feet. The three design plans
(rip -rap with geoextile, fabriform, and hydroturf) entailed the placement of rip -rap and
geotextile within the six-foot offset from the toe of the dam. The rip -rap with geotextile method
was determined to be the preferred alternative for the method of rearmament.
The singular wetland area within the project area was Wetland E, a riverine swamp forest.
Wetland E was conterminous with the 15-foot zone from the toe of the dam, which, as
permitted, would be permanently affected by dam rearmament and temporarily impacted by
vegetation removal. The total permanent and temporary wetland impacts from the Sutton Lake
Dam Rearmament and Vegetation Removal Project was calculated to be 6.38 acres. A total of
2.93 acres were to be permanently impacted, while a total of 3.45 acres were to be temporarily
impacted. The open water repair area to Sutton Lake (including the Intake Canals) was to
encompass 3.20 acres.

Compensatory mitigation for the permitted impacts for the Sutton Lake Dam Rearmament and
Vegetation Removal Project was satisfied through the purchase of riparian wetland mitigation
credits from the Lower Cape Fear Umbrella Mitigation Bank (Cape Fear River basin; Hydrologic
Unit 03030005). The mitigation requirement was 2.51 acres of riparian wetlands. In -lieu fee, on -
site mitigation, and off -site mitigation opportunities were not explored because the mitigation
bank option was already available.
Proposed Modification to USACE IP
The proposed modification to the issued USACE IP (SAW-2011-00858) and NCDEW-DWR
Certification (WQC004207) is necessary to address the following item of concern. This item of
concern must be resolved for completion (closure) of the Sutton Lake Dam Rearmament and
Vegetation Removal Project and to assure that the authorized activities onsite for the project are
in compliance with USACE regulatory requirements. The item of concern entails the additional
placement of stone (rip -rap) within the 15-foot zone (repair area) from the toe of the dam. The
stone was placed beyond (waterward of) the six-foot zone and was a field action that occurred
during the initial construction effort to armor the cleared zone with geotextile fabric and rip -rap.
Furthermore, the field change was based on engineering judgement, or necessity, that
additional armament would be required in specific observed locations. This action resulted in an
additional impact of 0.493 acre to Wetland E. Furthermore, this action was completed as based
on the need to clear tree and shrub vegetation from areas of armament within the 15-foot zone
from the toe of the dam.
The table below presents the impacts to jurisdictional wetlands (Wetland E) and open waters
(Sutton Lake and Intake Canal/Bay) as originally permitted by the USACE and as quantified from
the inadvertent placement of stone within the repair area, under the post -permit action.

The additional wetland impacts under the post -permit action are also presented on the attached
Plan View drawings of the impact areas.
The purpose of the post -permit activities as identified under this IP modification request was to
clear volunteer vegetation from the dam slope within additional (expanded) areas of armament
within the 15-foot zone from the toe of the dam, but beyond the first six feet. This purpose was
based on the following needs:
• To provide additional armament, or protection, waterward of the toe of the dam (area of
rip -rap; and
• To assure that the area of additional armament would be free of shrubby vegetation (i.e.,
which entailed the removal of shrubby vegetation) and the structural integrity of the
work area be uncompromised.
The needs of the project as originally completed are also applicable to the current action and
include:
• To facilitate regular dam safety inspections;
• Improve structural integrity of the Sutton Lake Dam by armoring the dam with geotextile
fabric and rip -rap to withstand future hurricane events; and
• To ensure the health and safety of citizens living downstream of the L.V. Sutton Energy
Complex.
Mitigation for the originally permitted 2.51-acre impact to Wetland E was provided through the
purchase of riparian wetland mitigation credits from the Lower Cape Fear Umbrella Mitigation
Bank. A 2:1 mitigation ratio was established. The North Carolina Division of Water Resources
received the acceptance letter from the Lower Cape Fear Umbrella Mitigation Bank (dated
March 4, 2020) to meet this mitigation requirement.
Mitigation for the additional impact of 0.493 acre to Wetland E will also be obtained through the
Cape Fear Umbrella Mitigation Bank. A mitigation ratio of 2:1 is proposed for 0.418 acre of
riparian wetland impact area within Bays 1, 2, 3, and 4 with a North Carolina Wetland
Assessment Method (NCWAM) overall rating of high for the functionality of those wetland

impacts areas. A mitigation ratio of 1:1 is proposed for 0.075 acre of riparian wetland impact
area within Bays 5 and 6 with a NCWAM overall rating of low or medium for the functionality of
those wetland impacts areas. As rounded to the one -hundredth place, the additional mitigation
that will be purchased from the Lower Cape Fear Umbrella Mitigation Bank will include the sum
of 0.84 credit and 0.08 credit, or a total of 0.92 credit. All of the wetland impact areas are
depicted on the attached updated Plan View drawings. The table below presents the proposed
compensatory mitigation amounts for the additional impacts to jurisdictional wetlands (Wetland
E) under the aforementioned post -permit action.

With regard to other resource consideration, the aforementioned post -permit activities that
were conducted onsite had no known effect on federally protected plant or animal species and
no effect on cultural resources or historic properties. These activities had no effect on
environmental justice for the surrounding residential communities; did not impact noise -
sensitive land uses; and did not impact air quality locally or regionally. Furthermore, impacts to
local or regional land use, aesthetics and visual resources, geologic features, biotic communities,
aquatic communities, and traffic and transportation were insubstantial.
