Polecat Mitigation Site INSTRUMENT MODIFICATION
Neu -Con Umbrella Bank ii May 2016
I INTRODUCTION
1.1 Project Description
The Polecat Mitigation Site (the "Site") is located two miles southeast of Smithfield and contains eight
parcels totaling 42 -acres in Johnston County, NC. The Site will involve the restoration and enhancement
of unnamed tributaries to Polecat Creek and Polecat Creek proper. The Site was identified by EBX-Neuse
I, LLC as having potential to help meet the compensatory mitigation requirements for stream impacts in
hydrologic unit 03020201 of the Neuse River Basin.
The conceptual design presents 12,195 linear feet of stream mitigation generating 9,563 Stream
Mitigation Units (SMU). In addition to the stream restoration, the Site is proposing to provide nutrient
offset mitigation and riparian buffer mitigation through the NC Division of Water Resources (DWR)
Neuse Riparian Buffer Mitigation program. The buffer and nutrient offset mitigation will be developed
through a separate banking instrument.
1.2 Project Location
The Polecat Site is located in Johnston County approximately two miles southeast of Smithfield, NC
(Figure 1). The GPS coordinates of the site are 35.476199°N and -78.312849°W. To access the site from
the town of Smithfield, head south on Mallard Road for approximately 1.5 miles.
1.3 Service Area
The Site will provide mitigation credits to offset unavoidable impacts to stream and wetland resources
within the Upper Neuse subbasin (8 -digit USGS HUC 03020201).
The Site is located within the Neuse River Basin (8 -digit USGS HUC 03020201, 14 -digit USGS
03020201140010). This proposed Site will result in significant ecological improvements including water
quality improvement, habitat restoration and a decrease in non -point source pollution from stormwater
and agricultural practices. The Site is located in the Polecat Creek Watershed, a Targeted Local
Watershed (TLW). The Site supports many of the Neuse River Basin Restoration Priorities Plan (RBRP)
and Neuse Regional Watershed Plan (RWP) goals.
The Site's watershed is primarily rural with Interstate 95 occupying the western portion of the watershed.
The project parcels have been in agricultural use for several decades (Figure 3). Water quality stressors
currently affecting the Site include livestock access, row crop production, and impervious surface. There
are no current conservation easements or options that conflict with the proposed mitigation bank.
All waters in the Neuse River basin are Impaired on an evaluated basis in the Fish Consumption category
for mercury contamination. This is based on fish consumption advice from the NC Department of Health
and Human Services (NC DHHS). Downstream in the Neuse River, low dissolved oxygen levels are
present.
1.4 Identified Watershed Needs
The North Carolina Division of Mitigation Services (DMS) develops River Basin Restoration Priorities
(RBRP) to guide its restoration activities within each of the state's 54 cataloging units. The 2010 Neuse
River Basin RBRP identified several restoration needs for the entire Neuse River Basin, as well as for
Polecat Mitigation Site INSTRUMENT MODIFICATION
Neu -Con Umbrella Bank 1 May 2016
HUC 03020201, specifically. Goals include promoting nutrient and sediment reduction in agricultural
areas by restoring and preserving streams, wetlands, and riparian buffers.
The proposed Site is designed to help meet these goals. The project will address stressors identified in the
watershed through nutrient removal, sediment removal, runoff filtration, and improved aquatic and
terrestrial habitat. These project goals will be achieved through stream enhancement and restoration.
1.5 Purpose and Objectives
The purpose of the proposed Site is to generate compensatory mitigation credits for inclusion in the Neu -
Con Umbrella Mitigation Bank in hydrologic unit 03020201 of the Neuse River Basin.
The project goals address stressors identified in the watershed, and include the following:
• Nutrient removal,
• Sediment removal,
• Invasive species removal,
• Filtration of runoff,
• Wildlife corridor enhancement and preservation, and
• Improved aquatic and terrestrial habitat.
The project goals will be addressed through the following project objectives:
• Elimination and control of exotic invasive species,
• Restoration of riparian forested stream buffers
• Stabilization of eroding stream banks due to lack of vegetation and livestock hoof shear,
• Addition of large woody debris such as log vanes, log weirs, and root wads, and
• Restoration of appropriate pattern, dimension, and profile in stream channels.
The proposed Site will provide numerous ecological and water quality benefits within the Neuse River
Basin. These benefits are not limited to the project area, but have more far-reaching effects throughout the
Neuse River. The Site will provide improvements to water quality, hydrologic function, and habitat.
1.6 Technical Feasibility
The technical feasibility of the bank is assured due to EBX-Neuse I, LLC's extensive experience with
stream and wetland restoration and enhancement in North Carolina and throughout the Southeast.
Examples of EBX-Neuse I, LLC's success with stream restoration and enhancement include Neu -Con
Umbrella Mitigation Bank sites: the Gregory, Nahunta, and Cox II Sites. The absence of fatal flaws such
as hydrologic trespass, and the absence of threatened and endangered species and their habitats mean the
project is unlikely to be impeded by resource issues, or by objections from landowners.
1.7 Site Ownership
The land required for the construction, management, and stewardship of this mitigation project includes
portions of the parcels listed in Table 1.

3 EXISTING CONDITIONS
3.1 Existing Jurisdictional Waters of the U.S.
Detailed wetland delineation has not been performed. The Site will be delineated and approved by the
USACE during the decision phase of the project.
Carolina Division of Water Quality methodology,
3.2 Soil Survey
3.2.1 General Soil Characteristics
The stream channels were classified using North
The Site is located in the Rolling Coastal Plains Physiographic Province. Existing soil information from
the Natural Resource Conservation Service (MRCS) shows the property is located within the Rains -
Goldsboro -Lynchburg soil association. This association is found on nearly level and gently sloping well
drained to poorly drained soils on uplands of the coastal plain region. This soil association is located on
broad level interstream areas that are relatively undissected by streams (Figure 4).
3.2.2 Site Mapped Soil Series
Site soils are mapped by the NRCS as Bibb, Cowarts, Goldsboro, Lynchburg, Toisnot, and Norfolk on the
low lying depressions and floodplains at the proposed project. Bibb, Goldsboro, Lynchburg, and Toisnot
soils are generally poorly drained sandy loam to loamy soils and range from 0 to 2 percent slopes.
Cowarts and Norfolk soils are typically loamy sands and are well -drained located on 0 to 6 percent slopes.
Bibb, Goldsboro, Lynchburg, and Toisnot soils are listed on the NRCS hydric soil list as hydric or having
hydric inclusions.
The surrounding upland soils are mapped as Cowarts, Gilead, and Norfolk. These soil types are typically
moderately well to well drained soils. Both Cowarts and Norfolk soils are loamy sands and are found on
slopes ranging from 2 to 6 percent. Gilead is a sandy loam soil and is generally mapped in locations
ranging from 2 to 8 percent slopes.
3.3 Endangered/Threatened Species
Plants and animals with a federal classification of endangered or threatened are protected under
provisions of Sections 7 and 9 of the Endangered Species Act of 1973, as amended. The US Fish and
Wildlife Service (USFWS) database (accessed 11 May 2016) lists four endangered species for Johnston
County, North Carolina: Red -cockaded woodpecker (Picoides borealis), Tar River spinymussel (Elliptio
steinstansana), Dwarf wedgemussel (Alasmidonta heterodon) and Michaux's sumac (Rhus michauxii).
No protected species or potential habitat for protected species was observed during preliminary site
evaluations (Table 2). The Bald eagle (Haliaeetus leucocephalus) is protected under the Bald and Golden
Eagle Protection Act (BGPA) and prohibits take of bald and golden eagles. No protected species or
potential habitat for protected species was observed during preliminary site evaluations.
Polecat Mitigation Site INSTRUMENT MODIFICATION
Neu -Con Umbrella Bank 5 May 2016
In addition to the USFWS database, the NC Natural Heritage Program (NHP) GIS database was consulted
to determine whether previously cataloged occurrences of protected species are mapped within one mile
of the project Site. Results from NHP indicated that there is one known occurrence west of the Site within
a one -mile radius of the project area. The NHP database documented a terrestrial habitat of Red -cockaded
woodpecker historically mapped in 1999. Based on initial site investigations, no impacts to federally
protected species are anticipated as a result of the proposed project. The environmental screening phase of
the project will include USFWS coordination to confirm these findings.

3.4 Vegetation and Wildlife
Current land use around the Site is primarily pasture, forest, and row crop. There are low-density
residential lots, maintained vegetation, and two-lane roads also present in the immediate project vicinity.
Forested riparian areas have been intermittently cattle -grazed and lack a well-developed understory and
shrub strata. These areas most closely resemble a disturbed Coastal Plain small stream swamp and are
dominated by hardwoods and loblolly pine (Pinus taeda). Canopy species include loblolly pine, blackgum
(Nyssa sylvatica), red maple (Acer rubrum), sweetgum (Liquidambar styraciflua), and willow oak
(Quercus phellos). Sub -canopy species include red cedar (Juniperus virginaiana) and American holly
(Ilex opaca).
Some exotics were noted, including Chinese privet (Ligustrum sinense), Nepalese browntop
(Microstegium vimineum), and Japanese honeysuckle (Lonicera japonica). Chinese privet and Nepalese
browntop are widespread and locally dense.
National Wetland Inventory (NWI) mapping depicts wetlands in the project area (Figure 5). During the
initial evaluation, riparian wetlands were identified but are not prevalent. All potential wetland areas in
the project corridor will be delineated during the mitigation plan phase of the project.
3.5 Cultural Resources
A review of North Carolina State Historic Preservation Office (SHPO) GIS Web Service (accessed 11
May 2016) database did not reveal any listed or potentially eligible historic or archeological resources in
the proposed project area. The environmental screening phase of the project will include SHPO
coordination to confirm these findings.
Polecat Mitigation Site INSTRUMENT MODIFICATION
Neu -Con Umbrella Bank 6 May 2016
3.6 Constraints
Several potential constraints are present or proposed on the Site. Up to four proposed crossings will be
constructed for landowner access in easement breaks. The crossings will utilize appropriate sized culverts
and floodplain culverts (if needed) and be fenced and gated to prevent livestock access to stream channels
in pasture areas. The Site is not located within five miles of an air transport facility (airport). The project
crosses Yelverton Grove Road (NCDOT) and EBX-Neuse I, LLC is proposing to utilize the existing
culvert and elevation. A 30 -foot powerline easement is located across the channel parallel to Yelverton
Grove Road. The proposed Atlantic Coast Pipeline (ACP) is currently shown crossing the upstream -most
project reach at an oblique angle. The pipeline route is still in preliminary planning and no easements or
landowner negotiations have occurred. RES will coordinate with ACP staff to ensure the Final Mitigation
Plan and construction plans adequately address the proposed pipeline. The ultimate site design will
minimize ACP impacts and protect the functional uplift of the mitigation project. Polecat Creek within the
project area is mapped as a FEMA 100 -year floodplain (Figure 6). RES and WK Dickson Project
Engineer will conduct a FEMA flood study to either obtain a No -Rise Certification or CLOMR/LOMR
from the Johnston County floodplain administrator. Construction access is slightly constrained in some
areas by existing mature hardwood vegetation. A tree survey will be conducted to design the mitigation
measures and access to minimize impacts to specimen trees.
4 PROPOSED BANK CONDITIONS
4.1 Conceptual Mitigation Plan
The Polecat Site presents the opportunity to provide up to 9,563 stream mitigation units. These will be
derived from Restoration, Enhancement Level I, Enhancement Level II, and Buffer Enhancement/Stream
Preservation. Table 3 details the mitigation types and SMUs generated. The proposed conceptual design
plan is shown in Figure 7.
This Site proposes to utilize the non-standard buffer width credit adjustment guidance for Piedmont and
Coastal Plain streams. This guidance allows for stream credit yields to be adjusted +7 percent for buffers
75 to 100 feet wide to +20 percent for buffers over 150 feet wide. The buffer adjustment for each bank is
averaged and to determine the final adjustment for that reach. The increased stream credit yield precludes
the use of the additional buffer area for riparian buffer mitigation.

4.1.1 Project Development
Proposed mitigation for the Site involves Restoration, Enhancement Level I, Enhancement Level II, and
Buffer Enhancement/Stream Preservation. The stream system is situated on an unnamed tributary to
Polecat Creek. Current stream conditions along the proposed restoration reaches demonstrate significant
habitat degradation as a result of impacts from livestock, row crop production, and historic land uses.
Polecat Mitigation Site INSTRUMENT MODIFICATION
Neu -Con Umbrella Bank 8 May 2016
The proposed mitigation approach is based on preliminary data collected, functional considerations, and
generally accepted practices in North Carolina. Over 20 cross sections were measured across the Site to
assess the stability of the stream bed and banks. Photographs were taken at all cross sections and at
selected locations throughout the Site to record general site conditions, including vegetation, stability, and
water quality issues.
Restoration reaches will typically include a meandering single -thread stream pattern constructed to mimic
the natural planform of a low -gradient, sand/gravel bed channel. Proposed sinuosity will depend on local
reference reach conditions and hydrologic and hydraulic modeling. As a result of the restoration of
planform and dimension, periodic flooding and restored riparian buffer will provide the appropriate
hydrology and sediment transport throughout this watershed (mitigation ratio l:1).
Enhancement Level I will include adjustments to the cross-sectional area of the existing channel and
floodplain; as well as installation of wood and rock structures to adjust and enhance bedform (mitigation
ratio 1.5:1). Enhancement Level Il treatments include livestock exclusion and bank stabilization
(mitigation ratio 2.5:1). Buffer Enhancement/Stream Preservation allows high quality aquatic habitat to be
protected and enhanced through invasive species treatments and supplemental plantings in the riparian
buffer (mitigation ratio 5:1). Invasive species treatment will occur throughout the easement area as
needed.
4.1.2 Stream Restoration and Enhancement
Stream restoration efforts will be accomplished through analyses of geomorphic conditions and watershed
characteristics. The design approach will apply a combination of analytical and reference reach based
design methods that meet objectives commensurate with both ecological and geomorphic improvements.
Proposed treatment activities may range from minor bank grading and planting to re-establishing stable
planform and hydraulic geometry. For reaches requiring full restoration or extensive enhancement, natural
design concepts will be applied and verified through rigorous engineering analyses and modeling. The
objective of this approach is to design a geomorphically stable channel that provides habitat
improvements and ties into the existing landscape.
The Site design approach will begin with a thorough study of existing conditions, including the on-site
streams and ditches, valleys, and watershed. Design parameters, including active channel, habitat and
floodplain features will be developed from analysis of suitable reference streams. Analytical design
techniques will be an important element of the project, and will be used to determine the design discharge
and to verify the design as a whole.
Engineering analysis will be performed using various hydrologic and hydraulic models to verify the
reference reach -based design. A combination of methods, including HEC -HMS, Hydraflow Hydrographs,
and flood frequency analysis, will be used to calculate flows received by the channel for bankfull and
other significant storm events. A HEC -RAS model will then be used to simulate water surface elevations
of flows generated by the hydrologic analysis. The development of the HEC models is an important
component to the design; therefore, model input parameters are field verified when possible. Through this
hydrologic analysis, the design discharge (typically referenced as bankfull or dominant discharge) will be
determined. The subsequent design will be based on this calculated discharge. Design parameters
developed through the analyses of reference reach data and hydrologic and hydraulic modeling will be
Polecat Mitigation Site INSTRUMENT MODIFICATION
Neu -Con Umbrella Bank 9 May 2016
confirmed using the Stable Channel Design function and/or the Sediment Transport Analysis components
within HEC -RAS.
Engineering analyses are performed concurrently with geomorphic and habitat studies. While stream
design will be verified by simulations of hydrology and fluvial processes, analogs of desirable habitat
features will be derived from reference sites and integrated into the project design. Both in -stream and
riparian habitat features will be designed. In -stream structures such as root wads, rock vanes, and cross
weirs will be used throughout the project to act as grade control and for bank stabilization by dissipating
and redirecting the stream's energy. Bank stability may be further enhanced through the installation of
brush mattresses and cuttings bundles consisting of species such as black willow (Salix nigra) and silky
dogwood (Cornus amomum).
In -stream habitat is highly dependent on available cover and organic material. A quantitative habitat
assessment method will be used to measure type, location, and quantity of habitat in the reference
streams. During design, the habitat assessment results will be scaled appropriately to the design
parameters such that the quantity and placement of the habitat features along the restored channel will
mimic reference conditions. This process provides a natural channel design that addresses aquatic
function improvements in addition to stability.
Stream banks will be stabilized using a combination of grading, erosion control matting, plantings, native
material revetment techniques (i.e., bioengineering), and structure placement. The stream and adjacent
riparian areas will be protected by a minimum 50 -foot permanent conservation easement which will be
fenced to exclude livestock as needed. In most areas the riparian buffer width will exceed 100 feet on
each bank.
The individual Reach Worksheets provide detailed information for each reach and the rationale for
proposed interventions.

Design Notes: Reach HL1, an intermittent channel, flows in a southerly direction through an agricultural field and has been historically ditched.
The channel has vertical banks, is oversized/entrenched, and the streambed is comprised of gravel, sand, and muck. The riparian buffer is in
poor condition and is comprised of row crops up to top of bank.
Enhancement activities will include regrading the channel by widening the banks and raising the bed such that cut and fill will be balanced. In -
channel structures, such as brush beds will be installed to increase organic matter in the system, while also providing stability and reductions in
sediment loads. The riparian buffers will be planted with native vegetation that will filter runoff from adjacent cultivated areas. The
improvement and protection of the riparian areas will also provide wildlife corridors throughout the project area. An agricultural BMP will be
installed at the upper end of the reach to provide nutrient/sediment control and flow attenuation from the adjacent agricultural fields.

Design Notes: Reach HL2 is an intermittent channel that flows in a southerly direction from Reach HL1 down to the confluence with PC1. The
reach begins to flatten shortly after the channel enters the wooded buffer/floodplain along PCI. Due to the change in gradient, the channel
lacks well-defined bed and bank features as sediment
from the eroding ditch and agricultural fields have filled the channel and deposited within
the PC -1 floodplain.
Enhancement activities will include regrading the channel by removing the sediment deposits. In -channel structures, such as log sills and brush
beds will be installed to increase organic matter in the system, while also providing stability and reductions in sediment loads.

reach is both laterally and vertically unstable and has been channelized. The channel has little to no forested buffer, livestock have direct access
to the channel and the resulting hoof shear has severely degraded the channel banks. A ford crossing is located at the downstream end of the
reach.
Restoration activities will include constructing a new channel with appropriate dimensions and pattern such that the floodplain is regularly
inundated. In-stream structures such as log grade controls and woody debris will be installed for vertical stability and to improve habitat.
Habitat will further be improved through buffer plantings and livestock exclusion. Livestock fencing will follow current NRCS specifications. The
existing ford crossing will be upgraded to allow access between pastures and parcel boundaries while also excluding livestock from stream
channels. Buffer improvements will filter runoff from adjacent pastures, thereby reducing nutrient and sediment loads to the channel. The

Design Notes: Reach K26, a perennial stream with a gravel bed, flows to the west from Yelverton Grove Road to the reach break with M11. The
reach has vertical and eroding banks, and the degree of incision/entrenchment increases through the middle and downstream portions of the
reach. The channel has a poor buffer along the upper end where there is little woody vegetation and maintained lawns along the right bank.
While the buffer along lower end is forested, the width averages less than 40 feet along the right bank.
Priority II restoration is proposed along the upper end due to elevation constraints at the Yelverton Grove Road culvert. Priority I restoration is
proposed along the middle and downstream portions of the reach. Restoration activities will include constructing a new channel that has
appropriate dimensions and pattern within the natural valley to the south such that the floodplain is regularly inundated. In-stream structures
such as log grade controls, brush toes, and log sills will be installed for vertical stability and to improve habitat. Habitat will further be improved
through buffer plantings. Buffer improvements will filter runoff from adjacent agricultural fields and maintained lawns, thereby reducing
nutrient and sediment loads to the channel. The widening and restoration of the riparian areas will also enhance wildlife corridors throughout
the project area.

Neu -Con Umbrella Bank 25 May 2016
4.1.3 Monitoring
Stream stability and vegetation survival will be monitored across both the restoration and enhancement
areas of the site to determine the success of the stream and buffer mitigation. Stream stability will be
monitored with cross section surveys and visual assessment stream walks. Vegetation survival rates will
be monitored using vegetation plots over approximately two percent of the planted area.
4.1.3.1 As -Built Survey
An as -built survey will be conducted following construction to document channel size, condition, and
location on constructed or modified channels. The survey will include a complete profile of Thalweg,
water surface, bankfall, and top of bank to compare with future geomorphic data. Longitudinal profiles
will not be required in annual monitoring reports unless requested by the IRT.
4.1.3.2 Visual Monitoring
Visual monitoring of all mitigation areas will be conducted a minimum of twice per monitoring year by
qualified individuals. The visual assessments will include vegetation density, vigor, invasive species, and
easement encroachments. Visual assessments of stream stability will include a complete streamwalk and
structure inspection. Digital images will be taken at fixed representative locations to record each
monitoring event, as well as any noted problem areas or areas of concern. Results of visual monitoring
will be presented in a plan view exhibit with a brief description of problem areas and digital images.
4.1.3.3 Cross Sections
Permanent cross-sections will be installed at a minimum of one per 20 bankfull widths with half in pools
and half in shallows. All cross-section measurements will include bank height ratio and entrenchment
ratio. Cross-sections will be monitored annually. There should be little change in as -built cross-sections.
If changes do take place, they should be evaluated to determine if they represent movement toward a less
stable condition (for example down -cutting or erosion), or are minor changes that represent an increase in
stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth
ratio). Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 2.2 within
restored reaches. Channel stability should be demonstrated through a minimum of two bankfull events
documented in the seven-year monitoring period.
4.1.3.4 Vegetative Success Criteria
Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover approximately two
percent of the planted area. The following data will be recorded for all trees in the plots: species, height,
planting date (or volunteer), and grid location. Monitoring will occur each year during the monitoring
period. The interim measures of vegetative success for the site will be the survival of at least 320 planted
three-year old trees per acre at the end of Year 3 and 260 five-year old trees per acre at the end of Year 5.
The final vegetative success criteria will be the survival of 210 trees per acre with an average height of 10
feet at the end of Year 7 of the monitoring period. Invasive and noxious species will be monitored and
controlled so that none become dominant or alter the desired community structure of the site. If necessary,
EBX-Neuse I will develop a species-specific control plan.

4.1.3.5 Adaptive Management
The Mitigation Plan will include a detailed adaptive management plan that will address how potential
problems are resolved. In the event that the site, or a specific component of the site, fails to achieve the
defined success criteria, EBX-Neuse I will develop necessary adaptive management plans and/or
implement appropriate remedial actions for the site in coordination with the IRT. Remedial actions will be
designed to achieve the success criteria specified previously, and will include identification of the causes
of failure, remedial design approach, work schedule, and monitoring criteria that will take into account
physical and climatic conditions. If tree mortality affects 40 percent or greater of the canopy in a stream
or wetland restoration area, then a remedial/supplemental planting plan will be developed and
implemented for the affected area(s).
5 BANK ESTABLISHMENT AND OPERATION
5.1 Establishment and Operation of the Bank
This Bank Parcel shall be established under the terms and conditions of the Neu -Con Umbrella Mitigation
Bank made and entered into by and among EBX-Neuse I, LLC, and the U.S. Army Corps of Engineers
and the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, the National Marine
Fisheries Services, the North Carolina Department of the Environment and Natural Resources, the North
Carolina Division of Water Resources, and the North Carolina Wildlife Resources Commission,
collectively, the Mitigation Banking Review Team.
5.2 Proposed Credit Release Schedule
All credit releases will be based on the total credit generated as reported by the as -built survey of the
Mitigation Site. The pre -construction credit release (15 percent) will be based on the credit total in the
Final Mitigation Plan. The second credit release will be based on the As -Built survey, and will adjust the
total released credits based on the actual constructed channel lengths. Under no circumstances shall any
mitigation project be debited until the necessary DA authorization has been received for its construction
or the District Engineer (DE) has otherwise provided written approval for the project in the case where no
DA authorization is required for construction of the mitigation project. The DE, in consultation with the
Interagency Review Team (IRT), will determine if performance standards have been satisfied sufficiently
to meet the requirements of the release schedule below. In cases where some performance standards have
not been met, credits may still be released depending on the specifics of the case. At the direction of the
DE, in consultation with the IRT, monitoring may be required to be extended, depending on the extent to
which the site fails to meet the specified performance standard. The release of project credits will be
subject to the criteria described in Table 4.

5.2.1 Initial Allocation of Released Credits
The initial allocation of released credits, as specified in the mitigation plan can be released by the IRT
with written approval of the DE upon satisfactory completion of the following activities:
1. Approval of instrument modification by the DE, in consultation with the IRT;
2. Approval of a final Mitigation Plan;
3. Confirmation that the Bank site has been secured;
4. Delivery of executed financial assurances as specified in the Mitigation Plan;
5. Delivery of a copy of the recorded long-term protection mechanism as described in the
Mitigation Plan, as well as a title opinion covering the property acceptable to the DE; and
6. Issuance of any DA permits necessary for construction of the Bank site (if necessary).
Polecat Mitigation Site INSTRUMENT MODIFICATION
Neu -Con Umbrella Bank 28 May 2016
5.2.2 Subsequent Credit Releases
The second credit release will occur after the completion of implementation of the Mitigation Plan and
submittal of the Baseline Monitoring Report and As -built Survey. All subsequent credit releases must be
approved by the DE, in consultation with the IRT, based on a determination that required performance
standards have been achieved. As projects approach milestones associated with credit release, the Sponsor
will submit a request for credit release to the DE along with documentation substantiating achievement of
criteria required for release to occur. This documentation will be included with the annual monitoring
report.
5.3 Financial Assurances
The Sponsor shall provide financial assurances in the form of a Performance Bond to the IRT sufficient to
assure completion of all mitigation work, required reporting and monitoring, and any remedial work
required. Financial assurances shall be payable at the direction of the USACE to his designee or to a
standby trust. Financial assurances structured to provide funds to the USACE in the event of default by
the Bank Sponsor are not acceptable. A financial assurance must be in the form that ensures that the
USACE receives notification at least 120 days in advance of any termination or revocation.
5.4 Proposed Ownership and Long -Term Management
EBX-Neuse I, LLC, acting as the Bank Sponsor, will establish a Conservation Easement, and will
monitor the Site for a minimum of seven years. The Mitigation Plan will provide detailed information
regarding bank operation, including long term management and annual monitoring activities, for review
and approval by the Interagency Review Team (IRT). Upon approval of the Sites by the IRT, the site will
be transferred to a long-term land steward (to be determined in the Mitigation Plan). The long-term
steward shall be responsible for periodic inspection of the site to ensure that restrictions required in the
Conservation Easement or the deed restriction document(s) are upheld. Endowment funds required to
uphold easement and deed restrictions shall be negotiated prior to site transfer to the responsible party.
The Bank Sponsor will ensure that the Conservation Easement will allow for the implementation of an
initial monitoring phase, which will be developed during the design phase and conducted by the Bank
Sponsor. The Conservation Easement will allow for yearly monitoring and, if necessary, maintenance of
the Site during the initial monitoring phase. These activities will be conducted in accordance with the
terms and conditions of the Neu -Con Wetland and Stream Umbrella Mitigation Bank made and entered
into by EBX-Neuse I, LLC, USACE, and NCDWQ.
5.5 Assurance of Water Rights
Sufficient water rights exist to support the long-term sustainability of the site, as there are no "severed"
rights on the property.
