The project streams and wetlands proposed for restoration have been significantly impacted by cattle grazing, channel relocation, and channelization. The project will involve the restoration, enhancement, and protection of streams and wetlands in the Broad River watershed. The site is located within the Broad River Basin and USGS 14 -digit HUC 03050105100030. The 2009 Broad River Basin River Basin Restoration Priorities (RBRP) identified several restoration needs for the entire Broad River Basin. HUC 03050105100030 was not identified as a Targeted Local Watershed (TLW), however because of the project's ability to meet stressor related goals it will still be beneficial to the Broad River Basin. The proposed Site includes streams that discharge into Buffalo Creek. Due to its location and proposed improvements, the Site will provide numerous ecological and water quality benefits within the Broad River Basin. While many of these benefits are limited to the project area, others, such as pollutant removal and improved aquatic and terrestrial habitat, have more far-reaching effects. The project presents 1,785 linear feet of Stream Restoration generating 1,785 Stream Mitigation Units (SMU) as well as 27.47 acres of wetland rehabilitation generating 13.74 Wetland Mitigation Units (WMU). Benefits include the storage of excess water during flood events, preventing erosion of stream banks, reducing in -stream sedimentation, and nutrient reduction. The Site encompasses 31.6 acres of actively managed floodplain with a single easement area. The easement is bordered by Buffalo Creek to the northwest and is partially used for cattle farming. Current stream and wetland conditions along the proposed reaches demonstrate habitat degradation as a result of impacts from livestock and a lack of riparian buffers. The objective for this Site is to restore and design natural waterways through stream/wetland complexes with appropriate cross-sectional dimension and slope that will provide function and meet the appropriate success criteria for the existing streams. Accomplishing this objective entails the restoration of natural stream characteristics, such as stable cross sections, planform, and in -stream habitat. The floodplain areas will be hydrologically reconnected to the channels where feasible to provide natural exchange and storage during flooding events. The design is based on reference conditions, USACE guidance (USACE 2005), and criteria that were developed during this project to achieve success. Additional site objectives, such as restoring the riparian buffer with native vegetation, ensuring hydraulic stability, and eradicating invasive species, are listed in Section 1. Restoration of Type C4/5 and E4/5 reaches will consist of constructing low to moderate sinuosity (1.1- 1.4) streams. Each stream type will be constructed with a moderate width -depth ratio (12.5-16) that accesses the floodplain at greater-than-bankfull flows. For stream reaches with average channel slopes from 0.5% to 0.6% the bed profile form is in a riffle -pool morphology. The profile is therefore a combination of riffle, run, pool, and glide features. Given the small sediment size, it is anticipated that the bed will be highly mobile and these features will adjust frequently. Wetland enhancement on Buffalo Creek will primarily involve removing livestock, planting native tree and shrub species commonly found in reference ecosystems, invasive species control, beaver control, and surface roughening to increase infiltration and storage. Mallard Restoration Plan ii November 2016 After completion of all construction and planting activities, the site will be monitored on a regular basis and a physical inspection of the site will be conducted at a minimum of twice per year throughout the five-year post -construction monitoring period, or until performance standards are met. These site inspections will identify site components and features that require routine maintenance. The measure of stream restoration success will be documented by bankfull flows and no change in stream channel classification. The measure of vegetative success for the site will be the survival of at least 260 five- year old planted trees per acre with an average height of five feet at the end of year five of the monitoring period.

The project streams and wetlands proposed for restoration have been significantly impacted by channelization and agricultural practices. Due to its location and proposed improvements, the site will provide numerous ecological and water quality benefits within the Broad River Basin. 1.1 Site Location The Site is located off of Mallard Drive, approximately 2 miles east of Earl in Cleveland County, NC. To access the Site from I-85, travel southwest on 29 S for 3.6 miles, turn right onto Carolina Avenue, merge onto Cleveland Avenue, travel northwest 2.2 miles and turn left onto Mallard Drive (Figure 1). The Site is located within the Broad River Basin, USGS 14 -digit HUC 03050105100030 (Figure 2). The Site is located in the Southern Outer Piedmont sub -region of the Piedmont ecoregion (Griffith et al. 2002). 1.2 Project Components The Site is comprised of a single easement area with one unnamed tributary and a drainage ditch that eventually drain downstream to Buffalo Creek. The Broad River is approximately seven miles downstream of the project. The stream and wetland components are summarized in Tables 1 and 2. Table 1.

Twenty-seven percent of the watershed is used for agricultural purposes and nine percent is currently developed. HUC 03050105100030 was not identified as a Targeted Local Watershed (TLW), however because of the project's ability to meet stressor related goals it will still be beneficial to the Broad River watershed. The Site is located within HUC 03050105 and includes streams that discharge into Buffalo Creek. The Site achieves the goals set forth for the Broad River Basin in the 2009 Broad RBRP, to implement wetland and stream restoration projects that reduce sources of sediment and nutrients by restoring riparian buffer vegetation, stabilizing banks, excluding livestock, and restoring natural geomorphology, especially in headwater streams. The project goals address stressors identified in the RBRP and include the following: • Nutrient removal • Sediment reduction • Invasive species treatment • Filtration of runoff • Improved aquatic and terrestrial habitat. The project goals will be addressed through the following project objectives: • Restoration of appropriate pattern, dimension, and profile in stream channels, • Restoration of forested riparian 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, root wads, and • Treatment and control of exotic invasive species. 2.1 Historical Land Use and Development Trends Aerial imagery indicates that the subject site has mostly been used for agriculture and has been surrounded by land that has been used for agricultural purposes or remained forested (Figure 3). Several watershed characteristics, such as groundwater, vegetation, surface drainage, and soil parameters have been modified. Soil structure and surface texture have been altered from intensive agricultural operations. 2.2 Soil Survey The soils within the Piedmont region of Cleveland County formed on uplands in material that weathered mainly from granite and gneiss. Much of the county is well drained; however, several areas are moderately drained to somewhat poorly drained. The Site is on the Hulett -Madison -Grover soil association (Figure 4). This association is found on uplands with subsoil that is clayey or loamy with a high content of mica. This soil association makes up approximately twelve percent of Cleveland County and is generally characterized by interfluves and side slopes. Project site soils are mapped by the Natural Resource Conservation Service (MRCS) as Chewacla, Dorian, Hulett, Madison, Toccoa, and Wehadkee (Table 3). Chewacla, Dorian, Toccoa, and Wehadkee soils are on the low lying depressions and floodplains at the site. Chewacla soils are loam, somewhat poorly drained, and range from zero to two percent slopes. Dorian is a sandy loam, moderately well Mallard Mitigation Plan 7 November 2016 drained, occurring on flats on stream terraces; slopes range from two to eight percent. Toccoa soils are loam, moderately well drained and generally occurring in flood plains; slopes range from zero to two percent. Wehadkee soils are loam, poorly drained, occurring on depressions on flood plains; slopes range from zero to two percent. The surrounding upland soils are mapped as Hulett and Madison. Hulett is a gravelly sandy loam, generally well drained, occurring on interfluves and hillslopes on ridges; slopes range from two to 15 percent. Madison is a gravelly sandy loam, generally well drained, occurring on interfluves; slopes range from two to 8 percent. Table 3.

This is a very deep, somewhat poorly drained soil that occurs on floodplains of the Piedmont and Coastal Plain river valleys. They formed in alluvium, and generally occur on slopes between zero and two percent. Runoff is negligible to very low, and permeability is moderate. Major uses are cropland, pasture, and some forest. Chewacla loam is the predominant soil throughout the existing streams occurring along the bed, streambanks and floodplains. Dorian sandy loam. This is a very deep, moderately well -drained soil that occurs on stream terraces of the Piedmont. They formed from clayey fluvial sediments, and generally occur on slopes between zero to two percent. Runoff is low, and permeability is slow. This soil type is mostly found in pasture. Dorian sandy loam occurs along the eastern and western edge of the target parcel. Grover gravelly sandy loam. This is a very deep, well -drained soil that occurs on the ridges and side slopes on Piedmont uplands. They formed from weathered high-grade metamorphic rocks high in mica such as biotite gneiss and schist, and generally occur on slopes between 15 and 30 percent. Runoff is medium to rapid, and permeability is moderate. This soil type is found on the western part of the parcel. Hulett gravelly sandy loam. This is a very deep, well -drained soil that occurs on the uplands of the Piedmont Plateau. They formed in residuum weathered from acid micaceous metamorphic rocks, and generally occur on slopes between two to 15 percent. Runoff is medium, and permeability is moderate. Mallard Mitigation Plan 8 November 2016 Major uses are cultivated crops and forests of pine and mixed hardwoods. Hulett gravely sandy loam occur along the lower reaches of the proposed stream. Madison gravelly sandy clay loam. This is a very deep to moderately deep, well -drained soil that occurs on the gently sloping to steep uplands in the Piedmont. They formed in residuum weathered from felsic or intermediate, high grade metamorphic or igneous rocks high in mica content, and generally occur on slopes between two and eight percent. Runoff is medium to rapid, and permeability is moderate. Major uses are cultivation or pasture, and some forest. Madison gravelly sandy clay loam occur along the western edge of the parcel. Toccoa loam. This is a moderately deep, well -drained to moderately well -drained soil that occurs on the Piedmont and Upper Coastal Plain valleys. They formed in loamy and sandy alluvium from igneous and metamorphic rocks, and generally occur on slopes between zero and two percent. Runoff is very low, and permeability is moderately rapid. Major uses are cropland, hayland, and pasture. Toccoa loam occur along the northern edge of the target parcel. Wehadkee loam. This is a very deep, poorly drained to very poorly drained soil that occurs on flood plains along streams that drain from the mountains and Piedmont. They formed in loamy sediments washed from soils that formed from other metamorphic and igneous rocks, and generally occur on slopes between zero and two percent. Runoff is very slow, and permeability is moderate. Major uses are water tolerant hardwood forests, pasture, corn, and hay. Wehadkee loam occur along the floodplain of the proposed stream.

Land use within the watershed consists of 62% forest, 12% low-density residential, and 26% agricultural land. Impervious area covers less than I% of the total watershed. Baseline information is summarized in Table 5. 4.1.2 Surface Water Classification Buffalo Creek has been assigned a Class C classification (NCDEQ 2016). Waters classified as Class C waters are protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture. Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner (NCDWQ 2011). 4.2 Reach Summary Information In order to assess existing geomorphic conditions, cross section measurements were taken at two (2) locations within the site. These measurements were used to evaluate existing width -depth ratios, bank - height ratios, entrenchment ratios and stream classification (Appendix Q. Data utilized from reference reach surveys and the NC Rural Piedmont regional curve were used to compare the site conditions with regional hydraulic geometry relationships for bankfull cross sectional area and discharge. Due to the approach of this project being a Priority 1 channel relocation, stability of the existing channel was not further evaluated for existing erosional and depositional features, other than to note the large amounts of sand present and moving through the system. 4.2.1 UT1 The majority of UTI classifies as a Type E stream characterized by low to moderate width -depth ratios, however there are areas that are classified as G and C as well, depending on the depth of incision, access to floodplain, and width/depth ratios. Entrenchment ratios typically range from 1.5 to >3. The bank - height ratios on UT 1 are typically within the range of 1.1— 2.0. This suggests that future adjustments of the channel will occur in the form of widening of the bed width and pattern adjustments resulting in additional bank erosion. UTI enters the site from the south flowing through a flat, broad valley. Maintaining its south to north direction and relatively flat profile for the majority of the impacted reach, UTI runs over a sand bed before joining with a drainage ditch, flowing from the large adjacent wetland, and finally flowing into Buffalo Creek. Adjacent to the streams present location, the valley bottom is a wide pasture to the east. UT flows approximately 1,900 linear feet adjacent to a sand bed access road and the vegetated pasture to the east until its confluence with the drainage ditch and several hundred feet later, flows into Buffalo Creek. Inspection of the site topography suggests that the channel was realigned from its historic position along the center of the valley (now in pasture) to the western side of the valley for agricultural purposes. The contour mapping indicates that the center of the valley bottom is slightly lower to the east of the existing channel and that depression area is now functioning as a wetland. At the upstream end of UTI, a sand bed channel with constantly changing dimension and profile features, indicates highly mobile bed load. Throughput consists primarily of sand generated from the head of the watershed and on-site. At the downstream end of UTI, the average particle size remains sand, however additional input of silts and clays are present from suspended load due to backwater from Buffalo Creek. Additionally, numerous Mallard Mitigation Plan 13 November 2016 depositional features are present throughout the impacted reach, and are comprised of sand and small gravel. Subsequent to the initial channel relocation and straightening, the channel has continuously eroded its banks in an effort to re-establish proper dimension and pattern. Bank erosion has been further aggravated by adjacent agricultural practices and a minimal riparian buffer. 4.2.2 Vegetation Current land use in the vicinity of the project is primarily pasture, grazed wetlands, and disturbed forest. Agricultural practices and cattle grazing have contributed to the highly eroded channel throughout the easement. Beaver activity has led to tree mortality in the currently wooded area within the easement. 4.3 Wetland Summary Information 4.3.1 Existing Wetlands and Floodplain The valley bottom on both sides of UTI, which constitutes the historic alluvial floodplain, is approximately 100 acres, of which approximately 27.69 acres remain as jurisdictional wetlands. The floodplain has a down -valley slope of approximately 0.7% in the south to north direction. Although the floodplain has been severely impacted by past land use practices there is substantial evidence that a majority of this area was historically wetlands. In addition to the channel relocation, drainage ditching was installed to affect site drainage conditions. One main ditch is cut through the wetlands east of UT 1 and runs north to east towards confluence with UT 1 and then Buffalo Creek. The U.S. Fish & Wildlife Service (USFWS) National Wetland Inventory (NWI) Map maps the area north of the drainage ditch as a Freshwater Forested/Shrub Wetland (PFO IA) and the area to the south of the drainage ditch as a Freshwater Emergent Wetland (PEM1A) (Figure 6). A wetland delineation was performed in May 2016. Wetland boundaries were delineated using current methodology outlined in the 1987 U.S. Army Corps of Engineers (USACE) Wetland Delineation Manual (DOA 1987) and Regional Supplement to the U.S. Army Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region (Version 2.0) (U.S. Army Corps of Engineers 2010). Soils were characterized and classified using the Field Indicators of Hydric Soils in the United States, Version 7.0 (USDA-NRCS 2010). Wetland boundaries were marked with sequentially numbered wetland survey tape (pink/black striped). Flag locations were surveyed under the direction of a Professional Licensed Surveyor (PLS) with GPS and conventional survey (Figure 7). A Preliminary Jurisdictional Determination (PJD) was requested on September 7, 2016. When received, the PJD will be included in Appendix D. 4.4 Regulatory Considerations and Potential Constraints 4.4.1 Property Ownership, Boundary, and Utilities No utilities are located within the Site. Additionally, no exclusions are included in the easement. 4.4.2 FEMAIHydrologic Trespass UT 1 is located within the FEMA 100 -year floodplain (Zone AE) of Buffalo Creek, and the downstream end is located within the FEMA floodway (Figure 8). Hydraulic modeling will be required to determine that restoration activities will have no effect on 100 -year flood elevations downstream. No hydrologic Mallard Mitigation Plan 14 November 2016 trespass will be permitted to adjacent properties upstream or downstream of the project without approval of the affected landowners. FEMA coordination will be conducted independent of the Mitigation Plan as needed. 4.4.3 Environmental Screening and Documentation 4.4.3.1 Threatened and Endangered Species A desktop analysis and field investigation were conducted to evaluate federally protected species potentially occurring on the Site. The USFWS Information for Planning and Conservation (IPAC) online tool was consulted to determine if any threatened or endangered species managed or regulated by the USFWS may be affected by project -related activities at the Site. In addition to the USFWS IPAC tool, the October 2014 North Carolina Natural Heritage Program (NCNHP 2011) database of natural heritage element occurrences was also reviewed in GIS to identify rare species or unique habitats on- site, especially those listed in the USFWS database. According to the USFWS IPAC database review tool (USFWS 2015), two federally listed species may occur in proximity to the Site (Table 6). Table 6. Threatened and Endangered Species List Common Name Scientific Name Federal Status Record Status Flowering Plants: Dwarf-Flowerd heartleaf Hexastylis naniflora T Current Mammals Northern long-eared bat Myotis septentrionalis T Current Species and species habitat listed in the USFWS database were inspected for during the field investigation to determine whether or not they occur at the Site. Potential impacts to species and species habitat off site, downstream, and within the vicinity of the project were also considered. In summation, the biological conclusion for all threatened and endangered species listed in the USFWS database that could be potentially affected by project activities is "No Effect". Because the database search and field investigations determined that the biological conclusion for each species is "No Effect", no written concurrence from the USFWS is required. In addition to screening for federally protected species, the Fish and Wildlife Coordination Act requires consultation with state fish and wildlife agencies when "waters of any stream or other body of water are proposed or authorized, permitted or licensed to be impounded, diverted ... or otherwise controlled or modified". RES submitted a request to the North Carolina Wildlife Resource Commission (NCWRC) for review and comments on the Site on November 3, 2016 in regards to any potential impacts to fish and wildlife resources. Documentation is included in Appendix D. 4.4.3.1 Cultural Resources A review of the North Carolina State Historic Preservation Office (SHPO) GIS Web Service database revealed that there are no National Registered listings within a one -mile radius of the proposed project area. No architectural structures or archeological artifacts have been observed or noted during preliminary surveys of the Site. RES submitted a letter to the NC SHPO office on November 3, 2016 requesting a search of records to determine the presence of any areas of architectural, historic, or archaeological significance that may be affected by the Site. Documentation is included in Appendix D. Mallard Mitigation Plan 15 November 2016 5 FUNCTIONAL UPLIFT POTENTIAL The Stream Functions Pyramid Framework (Harman et. al. 2012) separates stream functions into five categories, ordered into a hierarchy, which communicate the interrelations among functions and illustrate the dependence of higher level functions (biology, physiochemical and geomorphology) on lower level functions (hydrology and hydraulics). Anticipated functional benefits and improvements within the project area, as based on the Function -Based Framework are outlined in Table 7. Table 7. Functional Benefits and Improvements Mallard Mitigation Plan 16 November 2016 Functional Objective Description Level (1-5) Benefit will be achieved through cattle exclusion and direct removal of fecal Nutrient removal inputs, filtering of runoff through buffer areas, the conversion of active farm 3,4 fields to forested buffers, and improved denitrification and nutrient uptake through buffer zones. Benefit will be achieved through the stabilization of eroding stream banks Sediment removal through cattle exclusion (passive) and bioremediation, bed loss will be 3 arrested with grade control structures, and reduction of sediment loss from re- forested pasture. Benefit will be achieved through the restoration of buffer areas that will Runoff filtration receive and filter runoff, thereby reducing nutrients and sediment 3 concentrations reaching aquatic resources. Benefit will be achieved through the enhancement of floodplain connectivity Water storage which will store more water during precipitation events than under current 1,2 drainage conditions. Restoration of Benefit will be achieved by restoring riparian buffer and wetland buffers to habitats hardwood ecosystems. 3 Improved substrate Substrate will become coarser as a result of the stabilization of stream banks and instream cover and an overall decrease in the amount fine materials deposited in the stream. 3 Addition of large Benefit will be achieved through the addition of wood structures as part of the woody debris restoration design. Such structures may include log vanes, root wads, log 3,4 weirs, and log toes. Reduced water temperature due to Benefit will be achieved through the restoration of canopy tree species to the 4 shading stream buffer areas. Mallard Mitigation Plan 16 November 2016 6 DETERMINATION OF CREDITS In accordance with the provisions of this mitigation plan, all credits will be used to compensate for impacts associated with the terms of the Plea Agreements and Judgements as part of the United States v. Duke Carolinas et al. Mitigation Order. The District Court for the Eastern District of North Carolina Western Division entered an order directing RES to implement mitigation measures on behalf of Duke Energy in accordance with the Mitigation Order. On October 27, 2015, RES submitted a final implementation plan which was reviewed and approved by all parties. Mitigation credits presented in these tables are projections based upon site design (Figure 9). Upon completion of site construction, the project components and credits will be revised to be consistent with the as -built condition. Table 8. Mitigation Credits 7 MITIGATION WORK PLAN 7.1 Description of Target Stream, Wetland and Vegetation Communities Reference reaches were sought to provide a target for design of the proposed streams. Searches were conducted first upstream and downstream of the Site and then into surrounding watersheds to find suitable references that contained comparable slope, bed material, and valley type. No reference condition channels were located in reasonable proximity, so reference data from another watershed in the NC Piedmont was utilized for design purposes, along with dimension data from the existing stream. The type E reference will be used for proposed type C streams since reference quality type C streams are difficult to locate in the Piedmont province and are often associated with more disturbed conditions. Additionally, the type E reference represents the evolutionary endpoint for type C streams once sediment loads have diminished in response to channel stabilization and upstream watershed stabilization.

Searches were conducted first upstream and downstream of the Site and then into surrounding watersheds to find suitable references that contained comparable slope, bed material, and valley type. No reference condition channels were located in reasonable proximity, so reference data from another watershed in the NC Piedmont was utilized for design purposes, along with dimension data from the existing stream. The type E reference will be used for proposed type C streams since reference quality type C streams are difficult to locate in the Piedmont province and are often associated with more disturbed conditions. Additionally, the type E reference represents the evolutionary endpoint for type C streams once sediment loads have diminished in response to channel stabilization and upstream watershed stabilization. Mallard Mitigation Plan 17 November 2016 The reference reaches were selected to represent the probable configurations for the proposed stream. Detailed geomorphic survey was conducted on Sal's Branch in the Piedmont and Flat Creek in the Coastal Plain to acquire needed dimension, pattern, and profile data from use in the design of UT 1. Sal's Branch Reference The Sal's Branch reference reach is located in the Piedmont hydro -physiographic region of North Carolina. The watershed has many characteristics in common with UTI watershed including average annual rainfall, valley type, and (desired) substrate composition. The reference watershed is located in Umstead State Park area and is entirely forested. The drainage area for the Sal's Branch reference is 0.2 mit. Sal's Branch reference reach is representative of an E4 channel in a moderately sloped valley with a relatively broad floodplain. Bed material, channel slope and valley form of this stream are somewhat consistent with the Site and provide reasonable analogues for the potential channel forms that can be expected at the Site. The Sal's Branch reference reach has a D50 of 8 mm, D84 of 10 mm, channel slope of 1%, width/depth ratio of 7 to 9 and sinuosity of 1.1 to 1.3. Flat Creek Coastal Plain Tributary Reference The Flat Creek reference reach is located in the Upper Coastal Plain hydro -physiographic region of North Carolina. The watershed has characteristics in common with the project reach, UTI, including average annual rainfall, valley type, and existing substrate composition. The reference watershed is located near Fort Bragg in Hoke County and is predominately forested. The drainage area for the Flat Creek reference is 7.6 mi2. The Flat Creek reference reach is representative of an E5 channel in a moderately sloped valley with a relatively broad floodplain. Bed material, channel slope and valley form of this stream are somewhat consistent with the Site and provide reasonable analogues for the potential channel forms that can be expected at the Site. The Flat Creek reference reach has a D50 of 1.3 mm, D84 of 4 mm, channel slope of 0.7%, width/depth ratio of 10 and sinuosity of 1.1 to 1.3. 7.1.1 Reference Discharge and Bankfull Verification Bankfull was readily identified on the reference reaches as it exhibited consistent indicators throughout the reaches. Verification of bankfull was accomplished by plotting the bankfull cross sectional area against the regional curve data. The data indicates that the bankfull identified in the surveyed reach is within the confidence intervals of the regional curve and consistent with the range of data collected in the rural Piedmont regional curve study. 7.1.2 Reference Channel Stability Assessment A detailed channel stability assessment was not performed for these reaches since the bank and bed stability was apparent from observation. Subsequent review of the surveyed dimensions confirmed that width -depth ratios and bank -height ratios were within the appropriate range for stable, self -maintaining streams. Additional observations included significant upstream and downstream reconnaissance to identify any past, present, or future signs or sources of degradation. 7.1.3 Reference Vegetation Communities The target vegetation communities for the Site will be Piedmont/Mountain Bottomland Forest in the riparian wetlands and riparian areas. According to Schafale and Weakley the Piedmont/Mountain Bottomland Forest canopy is comprised primarily of mesic bottomland species such as tulip poplar (Liriodendron tulipifera), sweetgum (Liquidambar styraciflua), hackberry or sugarberry (Celtic Mallard Mitigation Plan 18 November 2016 occidentalis/laevigata), green ash (Fraxinus pennsylvanica), and bitternut hickory (Carya cordiformis). The understory can be diverse, and includes species such as ironwood (Carpinus caroliniana), American holly (Ilex opaca), and red maple (Acer rubrum). Vines are prominent, and include poison ivy (Toxicodendron radicans), various greenbriers (Smilax spp.), grapes (Mitis spp.), and Virginia creeper (Parthenocissus virginianus). Herbs are also diverse, and can include multiple types of sedges (Carex spp.), river oats (Chasmanthium latifolium), violets (Viola spp.), jumpseed (Persicaria virginiana), jack-in-the-pulpit (Arisaema triphyllum), and Virginia rye grass (Elymus virginicus). 7.2 Design Parameters 7.2.1 Stream Restoration Approach UTI is divided into two sub -reaches; based on potential connectivity to the existing wetland area. The Upper and Lower reaches are relatively flat and are both proposed for a Priority I restoration. The Upper reach (UTI) is designed as a type E4 stream with moderate sinuosity and an average channel slope of 0.6%. The Lower reach is proposed for Priority I restoration as a type C4 stream with low sinuosity and an average slope of 0.5%. It is anticipated that this reach will evolve to an E4 stream type as vegetation and deposition allow the channel to narrow. A portion of the downstream end of the Lower reach will require Priority 11 restoration in order to transition back to the existing drainage feature. The existing degraded stream conditions sufficiently warrant complete reconstruction of the reach; however, equally as important is raising the stream profile to reconnect it to the floodplain, which will enhance the wetland areas. Reconstruction of the channel will provide for configuration of proper cross sectional geometry that will reduce stress on the banks and eliminate bank scour. Riffles will be constructed from native gravel material along with in -stream structures, and will provide immediate habitat features and a dramatic functional lift. 7.2.1.1 Design Methods Stream Restoration Restoration of Type C4/5 and E4/5 reaches will consist of constructing a low to moderate sinuosity (1.1-1.4) streams. Each stream type will be constructed with a moderate width -depth ratio (12.5-16) that accesses the floodplain at greater-than-bankfull flows. For stream reaches with average channel slopes from 0.5% to 0.6% the bed profile form is in a riffle -pool morphology. The profile is therefore a combination of riffle, run, pool, and glide features. Given the small sediment size, it is anticipated that the bed will be highly mobile and these features will adjust frequently. Exploration for buried bed material will be conducted in proximity of the channel work to harvest available bed material for reuse in the constructed channel. Where the quantity of existing bed material is insufficient it will be supplemented with off-site material of appropriate size. In some locations topographic constraints prevent Priority I restoration and it will be necessary to construct a bankfull bench. Along these reaches, topsoil will be removed prior to excavation and stockpiled. After completion of grading operations, topsoil will be redistributed across the floodplain bench to facilitate vegetation success. Log and/or rock structures will be used to provide vertical stability to the channel, assist in maintaining riffle, run and pool features, and to provide habitat features. Small brush -toe structures may be installed on the outside of meander bends to provide an anchor for bank stability, increase bank roughness, and provide aquatic habitat. Mallard Mitigation Plan 19 November 2016 Earthwork activities will include excavation of the proposed channels, partial or complete backfilling of existing channels and removal of existing spoil berms. Grading work is designed to restore or mimic natural contours. 7.2.2 Wetland Enhancement The Site offers a total ecosystem restoration opportunity. As such, the wetland enhancement is located along the floodplains of the streams, and closely tied to the stream restoration. Proposed wetland enhancement will be treated with a credit ratio of 2:1. The primary wetland treatment will be re -planting the disturbed pastures as forested wetlands and excluding livestock from the pasture and currently grazed forested wetlands. In addition, in the currently forested areas where beaver activity has led to tree mortality, supplemental planting will occur at a lower planting density. Other enhancement activities will include invasive species control and surface roughening to increase infiltration and storage. Combined with the proposed stream restoration, these actions will result in a sufficiently high water table and flood frequency to support hydrophytic vegetation and wetland hydrology, resulting in enhanced riparian wetlands. 7.2.3 Plant Community Restoration The selection of plant species is based on what was observed at the reference reach, species present in the forest surrounding the restoration site, and what is typically native to the area. Several sources of information were used to determine the most appropriate species for the restoration project. Piedmont/Mountain Bottomland Forest will be the target community type and will be used for all areas within the project. The plant species list has been developed and can be found in Table 9 and on Figure 10. Species with high dispersal rates are not included because of local occurrence, adjacent seed sources, and the high potential for natural regeneration. The high dispersal species include red maple, tulip poplar, and sweetgum. The restoration of plant communities along the Site will provide stabilization and diversity. For rapid stabilization of the stream banks (primarily outside meanders), silky dogwood (Cornus amomum), cottonwood (Populus deltoides), and buttonbush (Cephalanthus occidentalis) were chosen for live stakes along the restored channel because of their rapid growth patterns and high success rates. 7.2.4 On -Site Invasive Species Management Control for invasive species will be required within all grading limits associated with stream restoration. Invasive species will require different and multiple treatment methods, depending on plant phenology and the location of the species being treated. All treatment will be conducted so as to maximize its effectiveness and reduce chances of detriment to surrounding native vegetation. Treatment methods will include mechanical control (cutting with loppers, clippers, or chain saw) and chemical control (foliar spray, cut stump, and hack and squirt techniques). Plants containing mature, viable seeds will be removed from the site and properly disposed. All herbicide applicators will be supervised by a certified ground pesticide applicator with a North Carolina Department of Agriculture and Consumer Services (NCDA&CS) license and adhere to all legal and safety requirements according to herbicide labels and NC and Federal laws. Management records will be kept on the plant species treated, type of treatment employed, type of herbicide used, application technique, and herbicide concentration and quantities used. These records will be included in all reporting documents. Mallard Mitigation Plan 20 November 2016 Table 9.

Any topsoil that is removed during construction will be stockpiled and placed over the site during final soil preparation. This process should provide favorable soil conditions for plant growth. Rapid establishment of vegetation will provide natural stabilization for the site. All disturbed areas will be stabilized with temporary and permanent seed and covered with straw or mulch. Stream banks will be stabilized using a combination of erosion matting, bare -root plantings, and bio -engineering techniques in accordance with the plans in Appendix E. The entire conservation easement area will be planted with bare root seedlings in accordance with the planting plan. The restored stream channels will be protected by a conservation easement that includes a riparian buffer of at least 50 feet and the enhanced wetland areas will be included in the conservation easement. Mallard Mitigation Plan 21 November 2016 The easement boundary for the stream and wetlands will be delineated by 10 -foot metal poles labeled with conservation easement signs. 8 MAINTENANCE PLAN The Site will be monitored on a regular basis and a physical inspection will be conducted a minimum of once per year throughout the post construction monitoring period until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance should be expected most often in the first two years following site construction and may include the following: Table 10. Maintenance Plan Component/Feature Maintenance through project close-out Stream Routine channel maintenance and repair activities may include chinking of in -stream structures to prevent piping, securing of loose coir matting, and supplemental installations of live stakes and other target vegetation along the channel. Areas where stormwater and floodplain flows intercept the channel may also require maintenance to prevent bank failures and head - cutting. Stream maintenance activities will be documented and reported in annual monitoring reports. Stream maintenance will continue through the monitoring period. Vegetation Vegetation shall be maintained to ensure the health and vigor of the targeted plant community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species shall be controlled by mechanical and/or chemical methods. Any vegetation control requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. Vegetation maintenance activities will be documented and reported in annual monitoring reports. Vegetation maintenance will continue through the monitoring period. Site Boundary Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries will be marked with signs identifying the property as a mitigation site, and will include the name of the long-term steward and a contact number. Boundaries may be identified by fence, marker, bollard, post, tree -blazing, or other means as allowed by site conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as -needed basis. Easement monitoring and staking/signage maintenance will continue in perpetuity as a stewardship activity. Livestock Fencing Livestock fencing is to be placed outside the easement limits. Maintenance of fencing is the responsibility of the landowner. Beaver Routine site visits and monitoring will be used to determine if beaver management is needed. If beaver activity poses a threat to project stability or vegetative success, RES will trap beavers and remove impoundments as needed. All beaver management activities will be documented and included in annual monitoring reports. Beaver monitoring and management will continue through the monitoring period. Mallard Mitigation Plan 22 November 2016 9 PERFORMANCE STANDARDS The success criteria for the Site will follow approved performance criteria presented in the Stream Mitigation Guidelines issued in April 2003 by the USACE and NCDWQ. Specific success criteria components are presented in this section. 9.1 Stream Restoration Success Criteria 9.1.1 Bankfull Events Two bankfull flow events must be documented within the five-year monitoring period. The two bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until two bankfull events have been documented in separate years. 9.1.2 Cross Sections There should be little change in as -built cross-sections. If changes do take place, they should be evaluated to determine if they represent a 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). Cross-sections shall be classified using the Rosgen stream classification method, and all monitored cross-sections should fall within the quantitative parameters defined for channels of the design stream type. 9.1.3 Digital Image Stations Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should not indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A series of images over time should indicate successional maturation of riparian vegetation. 9.2 Vegetation Success Criteria Specific and measurable success criteria for plant density within the riparian buffers on the site will follow USACE Guidance. Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover a minimum of two percent of the planted area. Vegetation monitoring will occur annually in the fall of each year. The interim measure 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 the final vegetative success criteria will be 260 trees per acre at the end of Year 5. The site will include eighteen (18) monitoring plots to monitor the 22.9 planted acres. Success criteria for the supplemental planting area will be 50% survival rate of planted stems. Volunteer trees will be counted, identified to species, and included in the yearly monitoring reports, but will not be counted towards the success criteria of total planted stems. Mallard Mitigation Plan 23 November 2016 10 MONITORING REQUIREMENTS Annual monitoring data will be reported using the USACE Monitoring Report Templates. The monitoring report shall provide a project data chronology that will facilitate an understanding of project status and trends, research purposes, and assist in decision making regarding project close-out. The success criteria for the Site will follow current accepted and approved success criteria presented in the USACE Stream Mitigation Guidelines, and subsequent third -party guidance. Specific success criteria components are presented in Table 11. Monitoring reports will be prepared annually and submitted to a third -party reviewer. Table 11.

The survey will include a complete profile of Thalweg, water surface, bankfull, and top of bank to compare with future geomorphic data. Longitudinal profiles will not be required in annual monitoring reports. Stream channel stationing will be marked with stakes placed near the top of bank every 200 feet. Mallard Mitigation Plan 24 November 2016 10.2 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. Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal photos should indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral photos should not indicate excessive erosion or continuing degradation of the banks over time. A series of photos over time should indicate successional maturation of riparian vegetation. 10.3 Cross Sections Permanent cross-sections will be installed at a minimum of one per 20 bankfull widths with half in pools and half in riffles. 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 five-year monitoring period. 10.4 Vegetative Success Criteria Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover a minimum of two percent of the planted area. There will be 18 plots within the planted area (22.9 acres). Existing wooded areas are not included in 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. In addition to the vegetation plots, two fixed 300 -foot line transects will be established in the supplemental planting area to monitor a total of 30 trees, roughly three percent of the total planted stems. Similar to the vegetation monitoring plots, the following data will be recorded for all trees in the transect: species, height, and planting date. 10.5 Scheduling/Reporting As -built drawings documenting stream and wetland restoration activities will be developed within 60 days of the planting completion on the mitigation site. The report will include all information required by IRT mitigation plan guidelines, including elevations, photographs and sampling plot locations, gauge locations, and a description of initial species composition by community type. The report will also include a list of the species planted and the associated densities. Baseline vegetation monitoring will include species, height, date of planting, and grid location of each stem. Mallard Mitigation Plan 25 November 2016 11 LONG-TERM MANAGEMENT PLAN Upon third -party approval for site closeout, the site will be transferred to the US Land Conservancy. This party 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. 12 ADAPTIVE MANAGEMENT PLAN Upon completion of site construction, RES will implement the post -construction monitoring protocols previously defined in this document. Project maintenance will be performed as described previously in this document. If, during the course of annual monitoring, it is determined that the Site's ability to achieve site performance standards are jeopardized, RES will notify the third -parry reviewer of the need to develop a Plan of Corrective Action. Once the Corrective Action Plan is prepared and finalized RES will: 1. Notify the third -party reviewer. 2. Revise performance standards, maintenance requirements, and monitoring requirements as necessary and/or required by the third -party reviewer. 3. Obtain other permits as necessary. 4. Implement the Corrective Action Plan. Mallard Mitigation Plan 26 November 2016 13 OTHER INFORMATION 13.1 References Amoroso, J.L., ed. 1999.

ARTICLE VI MISCELLANEOUS A. Warran . Grantor warrants, covenants and represents that it owns the Property in fee simple, and that Grantor either owns all interests in the Property which may be impaired by the granting of this Conservation Easement or that there are no outstanding mortgages, tax liens, encumbrances, or other interests in the Property which have not been expressly subordinated to this Conservation Easement. Grantor further warrants that Grantee shall have the use of and enjoy all the benefits derived from and arising out of this Conservation Easement, and that Grantor will warrant and defend title to the Property against the claims of all persons. B. Subsequent Transfers. The Grantor agrees to incorporate the terms of this Conservation Easement in any deed or other legal instrument that transfers any interest in all or a portion of the Property. The Grantor agrees to provide written notice of such transfer at least thirty (30) days prior to the date of the transfer. The Grantor and Grantee agree that the terms of this Conservation Easement shall survive any merger of the fee and easement interests in the Property or any portion thereof and shall not be amended, modified or terminated without the prior written consent and approval of the Corps. C. Assignment. The parties recognize and agree that the benefits of this Conservation Easement are in gross and assignable provided, however that the Grantee hereby covenants and agrees, that in the event it transfers or assigns this Conservation Easement, the organization receiving the interest will be a qualified holder under N.C. Gen. Stat. § 121-34 et seq. and § 170(h) of the Internal Revenue Code, and the Grantee further covenants and agrees that the terms of the transfer or assignment will be such that the transferee or assignee will be required to continue in perpetuity the conservation purposes described in this document. D. Entire Agreement and Severability. This instrument sets forth the entire agreement of the parties with respect to the Conservation Easement and supersedes all prior discussions, negotiations, understandings or agreements relating to the Conservation Easement. If any provision is found to be void or unenforceable by a court of competent jurisdiction, the remainder shall continue in full force and effect. E. Obligations of Ownership. Grantor is responsible for any real estate taxes, assessments, fees, or charges levied upon the Property. Grantor shall keep the Property free of any liens or other encumbrances for obligations incurred by Grantor. Grantee shall not be responsible for any costs or liability of any kind related to the ownership, operation, insurance, upkeep, or maintenance of the Property, except as expressly provided herein. Nothing herein shall relieve the Grantor of the obligation to comply with federal, state or local laws, regulations and permits that may apply to the exercise of the Reserved Rights. F. Extinguishment. In the event that changed conditions render impossible the continued use of the Property for the conservation purposes, this Conservation Easement may only be extinguished, in whole or in part, by judicial proceeding. G. Eminent Domain. Whenever all or part of the Property is taken in the exercise of eminent domain so as to substantially abrogate the Restrictions imposed by this Conservation Easement, Grantor and Grantee shall join in appropriate actions at the time of such taking to recover the full value of the taking, and all incidental and direct damages due to the taking. H. Proceeds. This Conservation Easement constitutes a real property interest immediately vested in Grantee. In the event that all or a portion of this Property is sold, exchanged, or involuntarily converted following an extinguishment or the exercise of eminent domain, Grantee shall be entitled to the fair market value of this Conservation Easement. The parties stipulate that the fair market value of this Conservation Easement shall be determined by multiplying the fair market value of the Property unencumbered by this Conservation Easement (minus any increase in value after the date of this grant attributable to improvements) by the ratio of the value of this easement at the time of this grant to the value of the Property (without deduction for the value of this Conservation Easement) at the time of this grant. The values at the time of this grant shall be the values used, or which would have been used, to calculate a deduction for federal income tax purposes, pursuant to Section 170(h) of the Internal Revenue Code (whether eligible or ineligible for such a deduction). Grantee shall use its share of the proceeds in a manner consistent with the purposes of this Conservation Easement. I. Notification. Any notice, request for approval, or other communication required under this Conservation Easement shall be sent by registered or certified mail, postage prepaid, to the following addresses (or such address as may be hereafter specified by notice pursuant to this paragraph): To Grantor: [Name, address and fax number] To Grantee: [Name, address and fax number] To the Corps: [Name, address and fax number] J. Failure of Grantee. If at any time Grantee is unable or fails to enforce this Conservation Easement, or if Grantee ceases to be a qualified grantee, and if within a reasonable period of time after the occurrence of one of these events Grantee fails to make an assignment pursuant to this Conservation Easement, then the Grantee's interest shall become vested in another qualified grantee in accordance with an appropriate proceeding in a court of competent jurisdiction. K. Amendment. This Conservation Easement may be amended, but only in a writing signed by all parties hereto, and provided such amendment does not affect the qualification of this Conservation Easement or the status of the Grantee under any applicable laws, and is consistent with the conservation purposes of this grant. L. [For use if there is a document describing the current condition of the property. The language provided is applicable if there is a mitigation plan that accurately describes the current condition and uses of the property. If there is not such a plan, another document we agree is accurate and can be identified and is in our files can be referenced.]Present Condition of the Property.

RHA SECTION 10 DETERMINATION OF JURISDICTION. There Are no "navigable waters of the U.S." within Rivers and Harbors Act (RHA) jurisdiction (as defined by 33 CFR part 329) in the review area. [Required] ❑ Waters subject to the ebb and flow of the tide. ❑ Waters are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. Explain: B. CWA SECTION 404 DETERMINATION OF JURISDICTION. There M "waters of the U.S." within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 328) in the review area. [Required] 1. Waters of the U.S. a. Indicate presence of waters of U.S. in review area (check all that apply): t ❑ TNWs, including territorial seas ❑ Wetlands adjacent to TNWs ® Relatively permanent waters' (RPWs) that flow directly or indirectly into TNWs ❑ Non-RPWs that flow directly or indirectly into TNWs ❑ Wetlands directly abutting RPWs that flow directly or indirectly into TNWs ❑ Wetlands adjacent to but not directly abutting RPWs that flow directly or indirectly into TNWs ❑ Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs ❑ Impoundments of jurisdictional waters ❑ Isolated (interstate or intrastate) waters, including isolated wetlands b. Identify (estimate) size of waters of the U.S. in the review area: Non -wetland waters: 325 linear feet: 5 width (ft) and/or acres. Wetlands: acres. c. Limits (boundaries) of jurisdiction based on: 1987 Delineation Manual Elevation of established OHWM (if known): 2. Non-regulated waters/wetlands (check if applicable):3 Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Boxes checked below shall be supported by completing the appropriate sections in Section III below. z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). s Supporting documentation is presented in Section 11I.F. SECTION HI: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.l. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections HI.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Ra arsas have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW?

Explain: Boxes checked below shall be supported by completing the appropriate sections in Section III below. z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). s Supporting documentation is presented in Section 11I.F. SECTION HI: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.l. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections HI.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Ra arsas have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1.

Tributaries of TNWs where tributaries typically flow year-round are jurisdictional. Provide data and rationale indicating that tributary is perennial: Stream is first order, flowing through large wetland. Stream displays characteristics of a perennial stream, including continuous bed and bank and substrate sorting. Shown as a 'dashed blue line' (intermittent) on USGS topographic quad map but the stream flow path has been significantly altered downstream from its confluence with SOI and its actual flow path is different than indicated on USGS quad maps. Additionally, stream scored 37 on NCDWR Stream Form. Of note are several large beaver dams across the ditched channel as it flows out to Buffalo Creek; these dams obscure features suchs as particle size/sorting and macrobenthos sampling along the downstream portion of the stream. Tributaries of TNW where tributaries have continuous flow "seasonally" (e.g., typically three months each year) are jurisdictional. Data supporting this conclusion is provided at Section III.B.

Wetlands directly abutting an RPW that flow directly or indirectly into TNWs. ® Wetlands directly abut RPW and thus are jurisdictional as adjacent wetlands. ® Wetlands directly abutting an RPW where tributaries typically flow year-round. Provide data and rationale indicating that tributary is perennial in Section III.D.2, above. Provide rationale indicating that wetland is directly abutting an RPW: Stream flows through a large wetland complex and into a ditched channel leading to Buffalo Creek. The wetland surrounds the stream on both sides and terminates when the stream cuts down into the ditched channel. Wetlands directly abutting an RPW where tributaries typically flow "seasonally." Provide data indicating that tributary is seasonal in Section III.B and rationale in Section III.D.2, above. Provide rationale indicating that wetland is directly abutting an RPW: S02, a perennial stream or RPW, flows through the wetland area and drains to Buffalo Creek. The origin of S02 is at the outfall of a blocked culvert that formerly drained the wetland; upstream waters (within the wetland) are now perched and ponded above the culvert, and it is not possible to see the upstream end of the pipe.

September 8, 2016 Daniel Ingram Resource Environmental Solutions, LLC 302 Jefferson Street, Suite 110 Raleigh, NC 27605 Dear Mr. Ingram, The following are comments concerning the feasibility document and field visit walkthrough of the Mallard Water Quality Improvement Site, located in Cleveland County, North Carolina. The site walkthrough occurred on August 31, 2016 and included representatives from Resource Environmental Solutions (RES) and Axiom Environmental, Inc. (AXE). The Feasibility Report for the site is dated August 2016. Mallard Site Overall, AXE agrees with the mitigation concept as outlined in the August 2016 feasibility report. Reach designations and proposed mitigation treatment for UT 1 appear suitable for site conditions; however, UT 2 appears to be a wetland and a stream determination will be required by the US Army Corps of Engineers or NC Division of Water Quality before stream mitigation credit may be derived through this section of the site. Feasibility Report comments include: 1) Existing Conditions — a watershed of 59 acres (0.01 square miles) for UT 2 may be insufficient to support a jurisdictional stream. Confirmation of jurisdiction through this reach may be necessary, as stated above. 2) Section 4.1.1 Stream and Buffer Restoration, second paragraph, last sentence - a credit ratio of 3:1 is proposed for the grazed, forested wetland areas." However, the woody vegetation through a large portion of this area has not survived ponded conditions due to beaver activity. AXE suggests supplemental planting in this area, implementing beaver control, and using a 2:1 credit ratio for this section. 3) Section 4. 1.1 Stream and Buffer Restoration, fourth paragraph, last sentence — "reconnecting low lying areas of hydric soil with the floodplain" is not a necessary or feasible wetland mitigation objective in a beaver -impacted area. Please remove this activity from the text. Page 1 of 2 4) UT 1 is currently situated on the property boundary. It is proposed to be moved off the property boundary and through the middle of the conservation easement. Documentation from the adjacent landowner will be required to avoid hydrologic trespass by moving the stream from the property boundary. Site visit comments include: 1) The jurisdictional boundaries for wetlands will be confirmed by the US Army Corps of Engineers to determine the extent of Wetland Enhancement at the Site. In addition, a jurisdictional determination of stream presence will occur on UT 2 if stream mitigation credit is to be derived from this reach. 2) Wetland Enhancement will be derived at a 2:1 ratio for the site. This includes previously wooded sections that have been flooded, causing trees to die. Wetland Enhancement will include planting suitable species throughout credit -generating areas. Oaks, hickories, and other species of high wildlife value constitute suitable species. Vegetation monitoring will occur in all planted areas, including previously wooded areas. Sincerely, AXIOM ENVIRONMENTAL, INC. W. Grant Lewis President Page 2 of 2 November 10, 2016 Axiom Environmental, Inc. 218 Snow Avenue, Raleigh, North Carolina 27603 919-215-1693 Daniel Ingram Resource Environmental Solutions, LLC 302 Jefferson Street, Suite 110 Raleigh, NC 27605 Dear Mr. Ingram; The following are comments concerning the Mallard Water Quality Improvement Site Draft Mitigation Plan, dated November 2016. The Site is located in Cleveland County, North Carolina. The project involves 1,785 linear feet of stream restoration and approximately 27 acres of wetland enhancement. Projects involving discharge of fill (temporary or permanent) into a jurisdictional stream and/or wetland will require notification of the action to the US Army Corps of Engineers and NC Division of Water Resources through the submittal of a Pre -Construction Notification (PCN) for a Nationwide Permit (NWP). This project will likely be conducted under a NWP #27, for "Aquatic Habitat Restoration, Establishment, and Enhancement Activities". As the project will be vetted through the regulatory agencies via the NWP process, third party review by Axiom Environmental, Inc. (AXE) for the United States v. Duke Carolinas et al. Mitigation Order will be limited to document review with minimal oversight. Draft Mitigation Plan comments include: 1) The document references UT 1 and UT 2 throughout. However, site visits indicate only one tributary occurs within the site boundaries. UT 2 appears to be a ditch through a wetland. 2) Executive Summary, eighth paragraph, first sentence — "reconnecting low lying areas of hydric soil with the floodplain" is not a necessary or feasible wetland mitigation objective in a beaver -impacted area. Please remove this activity from the text. Wetland enhancement will involve removal of livestock, planting, invasive species control, and beaver control. That should be sufficient to warrant wetland enhancement. 3) Watershed Approach, project goals - "Restoration of hydrology in disturbed and existing riparian wetlands". Please see comment 2 above. 4) Table 7, improved groundwater recharge — Please see comment 2 above. 5) Table 8, stationing for UT 2 ("Lower Reach" on construction plans) should match the attached construction plans for clarity. Page 1 of 2 6) Section 7.2.1 Stream Restoration Approach, seventh sentence — "raising the stream profile to reconnect it to the floodplain which is integral to success and function of the proposed wetland enhancement". Please see comment 2 above. 7) 7.2.2 Wetland Enhancement, sixth sentence — Please see comment 2 above. 8) Table 11, Parameter (dimension), frequency — "Baseline, Years 1, 2, 3, and 5". Year 4 should be added to the 5 year monitoring schedule. 9) Appendix C — Data Analysis — Please show the surveyed cross section locations on the existing conditions figure. This may explain why the XS 2 is almost half the bankfull cross sectional area as XS 1, even though the drainage area is larger. 10) Design Plan Sheets — please show the conservation easement on the plan sheets. This makes confirmation of proposed SMU's possible. 11) Design Plan Sheets 6 and 11 are blank. AXE believes the Mallard Draft Mitigation Plan (dated November 2016) conforms to State of North Carolina and Federal mitigation guidelines outlined in the following documents. • Part 332 (Compensatory Mitigation for Losses of Aquatic Resources) - 33 U.S.C. 401 et seq. ; 33 U.S.C. 1344; and Pub. L. 108-136 • USACE 2012. Wilmington District Mitigation Bank Prospectus Checklist • IRT 2009.

Stream Mitigation Considerations for the Coastal Plain of North Carolina • IRT 2013. Monitoring Requirements and Performance Standards for Compensatory Mitigation in North Carolina It the understanding of AXE that the project will be developed using a NWP #27 and regulatory authorities will be notified of proposed activities.
