It lies within the NCEEP targeted 14 -digit HUC 03020101010010 of the Tar- Pamlico River Basin and lies within a 228 -acre parcel owned by Roy and Joyce Huff (Figure 1). This is the Bank Parcel Development Package (BPDP) and Final Design Plan. TRH MB site encompasses nearly 3,800 linear feet of existing stream channel headwater tributaries to the Tar River and associated flood plain. The property is located at (N 36.391302, W - 78.817128). The tributaries are enclosed by a "brown polygon" on the attached US Geological Survey (USGS) Triple Springs 7.5 Minute Quadrangle Map (Figure 2), and are denoted as a "blue line" on the USGS Quad and the Soil Survey of Person County Map (Figure 3), (Sink, 1995). The landowners have agreed to allow the restoration and to place the land under a conservation easement so that the site will be protected in perpetuity. Cattle and other livestock will be excluded from the TRH MB site by means of proper fencing, A detailed boundary survey has been prepared (Appendix A, Figure 6) delineating the area to be protected under the conservation easement. Prior to debiting the easement will be recorded in the Person County Clerk's office. This site will be established under the terms and conditions of the Mogensen Mitigation, Inc. (MMI) Tar River Headwaters Riparian Buffer and Nutrient Offset Umbrella Mitigation Banking Instrument (UMBI) made and entered into by MMI, acting as the Bank Sponsor (Sponsor), and the North Carolina Department of Environment and Natural Resources - Division of Water Quality (DWQ). This document was signed on April, 09, 2013. The Sponsor proposes to restore approximately 7.5 acres of riparian buffer credit and 9.26 acres nutrient offset credit along the degraded headwater tributaries to the Tar River within a 17.7 acre project area (Appendix A, Figure 6). The project area is currently used for livestock grazing and contains ditches and channels that convey nutrients, sediment, and other agricultural pollutants directly into tributaries. Restoration of the riparian buffers will reduce sediment, nutrient, and other pollutant inputs from the project area, thereby improving the overall water quality of this headwater tributary and ultimately, to the Tar River. Areas of riverine wetlands will also be restored and/or created for additional habitat diversity in areas of the old, abandoned channels but are not a part of this BPDP. The objective of the restoration plan is to restore the primary riparian functions and services associated with nutrient removal and transformation, sediment retention, flood -flow attenuation, and wildlife (both aquatic and terrestrial) habitat. While many of these benefits are limited to the project area, others, such as pollutant removal and improved terrestrial and aquatic habitat, have more far- reaching watershed benefits. 2 h+l M1J •/r.r r q STE �{ 8 .

Elevations at the site range from approximately 560 feet above mean sea level (MSL) near the upstream property boundary at the main channel to approximately 550 feet above MSL at the downstream boundary. Valley slope is estimated at less than one percent and extends downslope from northeast to southwest across the property. Chewacla and Wehadkee (hydric) loam soils dominate the channel and floodplain within the project area. These soils are described as gently or moderately sloping, somewhat poorly to poorly drained soils that have a loamy surface layer and clayey subsoil. Based on the Soil Survey of Person County, North Carolina (Sink, 1995), Chewacla loam dominates the floodplain areas associated with the Tar River Headwaters site (Table 1, Figure 5). Chewacla loam is classified as a fine - loamy, mixed, thermic Fluvaquentic Dystrochrept. These soils are somewhat poorly drained soils formed in recent alluvium on nearly level floodplains along streams that drain from the Mountains and Piedmont physiographic provinces. Slopes range from 0 to 2 percent. Chewacla loam is noted as a Hydric B soil on the Hydric Soils of North Carolina list (MRCS, 1995). Chewacla soils also have inclusions of Creedmoor coarse sandy loam and small pockets of Wehadkee loam. Wehadkee loam is classified as a fine - loamy, mixed, nonacid, thermic Typic Fluvaquent. Wehadkee loam is a Hydric A soil that develops within lower swales of the floodplain. Slopes are considered nearly level and the soils are poorly drained. The site is located within the Carolina Slate Belt portion of the Piedmont physiographic region of North Carolina. Bedrock within the Carolina Slate Belt consists of volcanic argillites, basic and acid tuffs, breccias, and flows. Volcanic igneous rocks rise above the surrounding slates as high rolling hills and small mountains (Daniels et. al, 2005). Table 1. Mapped Soils within the Site Soil Type Hydrologic Soil Group General Description Fine - loamy, mixed, thermic Fluvaquentic Dystrochrept. Somewhat poorly drained soil formed in recent alluvium on Chewacla Loam HSG B nearly level floodplains along streams that drain from the Mountains and Piedmont physiographic provinces.

Slopes are considered nearly level and the soils are poorly drained. 4 Z2 Vegetative Communities The vegetation at the site is separated into two major groupings. These groupings are based primarily on topographical position and current land use. The first grouping is located within the lower section of the site downstream of the stream crossing immediately adjacent to the stream banks. A thin (often only one stem) riparian area is dominated by young to mature green ash (Fraxinus pennsylvanica), box elder (Acer negundo), ironwood (Carpinus caroliniana), willow oak (Quercus phellos), white oak (Quercus alba), sweetgum (Liquidambar styraciflua), tulip poplar (Liriodendron tulipifera), elderberry (Sambucus canadensis), Chinese privet (Ligustrum sinense), greenbrier (Smilax sp. ), and sawtooth blackberry (Rhubus argutus). This vegetation is partially managed and consists of far less than 100 trees per acre less than or equal to five inches dbh. The second grouping is located throughout the project area. This second vegetation grouping is located on land actively used as pasture for cattle and horses. The upper portion of the reach and a small tributary are barren of woody vegetation within their riparian areas and consist primarily of fescue (Festuca sp.) and other grasses and weeds. Sparse stands of red cedar (Juniperus virginiana) and black willow (Salix nigra) are located immediately upstream of the stream crossing. 23 Threatened and Endangered Species According to the US Fish and Wildlife Service ( USFWS), there is only one federally endangered species, (Alasmidonta heterodon) and nine federal species of concern potentially occurring in Person County, ( USFWS, 2013). In addition, The North Carolina Natural Heritage Program ( NCNHP) identifies another 18 species protected by the State of North Carolina. A review of the NCNHP database of documented occurrences ( NCNHP, 2012) revealed one occurrence of State Rare plants within one mile of the project site and one occurrence of a natural community. An occurrence of Glade wild quinine (Parthenium auriculatum) is present approximately 0.6 mile northwest of the site. A `Basic Oak - Hickory Forest' exists immediately adjacent to the north of the site. Habitat for threatened and endangered species does not currently exist on the project site. The proposed project is not likely to impact any protected species. Investigations will be conducted for each of these species and their appropriate habitat requirements as part of the TRH Mitigation Plan. A Section 7 (ESA) clearance will be obtained from the USFWS prior to restoration activities. A review of available databases was conducted to determine the proximity of Significant Natural Heritage areas to the project site. Several Natural Heritage occurrences are located immediately downstream of the project site in the Tar River. The Tar River downstream of the project site is listed as a proposed critical habitat area and a significant aquatic habitat (Figure 2). A clearance letter will be obtained from the NCNHP prior to restoration. Restoration of the site will provide additional habitat as well as reducing sediment and nutrient loads to the sensitive waters of the Tar River. 2.4 Cultural Resources No historic buildings or foundations were seen during initial field investigations. As such, there are no anticipated impacts to cultural resources as a result of the proposed restoration actions. MMI will conduct an environmental screening of the site using the Categorical Exclusion Action Classification Form prior to implementation of this plan. This will prevent adverse impacts to protected species or cultural resources from the proposed restoration actions. A review of properties to be determined eligible for the National Register of Historic Places at the State Historic Preservation Office (SHPO) was conducted for the study area and surrounding areas. According to the files, there are no National Register properties within a one -mile radius of the study area. In addition, the SHPO Archaeological Section was contacted in order to determine if documented archaeological sites occur at or near the study area. No sites were identified within a one -mile radius of the study area. MMI will obtain a Section 106 clearance letter from the SHPO prior to implementing the restoration plan. 2.5 Environmental Issues Preliminary data was obtained from Environmental Data Resources, Inc. (EDR) for the determination of potential on -site or nearby sources of contamination. According to the EDR databases, the TRH MB site is not listed in any search records. Additionally, there are no federal or state records within the required search distances of the TRH MB. 2.6 FEMA Floodplain /Floodway Mapping These streams are located within a region that is not mapped by FEMA, therefore no data exists. Therefore, CLOMAR and/or No Rise certification will not be required. 3.0 Proposed Riparian Buffer Restoration The Sponsor proposes to restore approximately 7.5 acres of riparian buffer along UT #1 and UT #2. The widths of the riparian buffers are measured from the edge of the ordinary high water mark (OHWM) outward to the easement boundary. These widths vary depending on resultant stream locations. Restoration would entail planting riparian buffers with native tree species found either within a reference riparian buffer or within the Piedmont Mesic Mixed Forest The Natural Communities of North Carolina; Third Approximation (Shafale and Wheatley, 1990). The goal would be to "jumpstart" the development of a native bottomland, hardwood climactic forest. Proposed riparian buffer restoration would be expected to enhance the geomorphic, hydrologic, and biologic functioning of the tributaries by restoring more natural hydrologic and sediment transport regimes, reducing temperatures, increasing dissolved oxygen levels, stabilizing soils, and improving wildlife habitat. The riparian buffer restoration area will be a Piedmont Alluvial Forest as described in Schafale and Weakley (1990). Although this type of palustrine floodplain system is typically small in size it is vulnerable to indirect damage by actions on adjacent lands. Table 2 lists proposed Piedmont Alluvial Forest trees and shrubs to be planted at the site. The Piedmont Alluvial Forest community typically has high species diversity in the tree and shrub layers because of the heterogeneous nature of small floodplains. Hardwood trees will be planted to mimic the natural communities. Trees and shrubs will be planted across the site, and grasses, sedges, and herbaceous plants will be concentrated around higher topographic areas. Additionally, non - native 6 invasive vegetation will be removed as needed. Appendix C contains detailed planting notes and graphics. Please make note that this Bank will be constructed in conjunction with an associated Stream Mitigation Bank that is currently proposed. Therefore, a 100' wide corridor will be used to generate buffer credits. Areas outside the 100' corridor will be used to generate nutrient offset credits (Appendix D). Table 2. Plant List Common Name Scientific Name Wetland Indicator Trees River Birch Betula nigra FACW Shagbark Hickory Carya ovata FACU Green Ash Fraxinus pennsylvanica FACW Tulip Poplar Driodendron tulipifera FAC White Oak Quercus albs FACU Northern Red Oak Quercus rubra FACU American Sycamore Platanus occidentalis FACW American Elm Ulmus americana FACW American Hornbeam (ironwood) Carpinus caroliniana FAC The buffer restoration meets the definitions set forth by North Carolina Administrative Code 15A NCAC 2B.0100. The conservation easement boundary will be marked by aluminum poles and metal conservation easement signs. Additionally, the entire conservation easement will be protected from livestock using approved fencing. Additional protection of the project area will not be a concern as the proposed conservation easement lies in the middle of the Huff Farm with extremely limited access from surrounding neighbors. The property parcel, where the project site is located, is bounded by a road, agriculture fields, and the forested riparian corridor of the Tar River Headwaters project site and a forested Natural Heritage Area. 4.0 Nutrient Offset Restoration The sponsor proposes to restore approximately 9.25 acres of Nutrient Offset zone. Nutrient offset credits will be available from 50' beyond the OHWM to 200' to the easement boundary. The first 50' surrounding the stream will generate riparian buffer restoration credits while the remaining 150' will generate nutrient offset credits. The sponsor will carry a ledger showing exact deductions in acreage and the type of credit associated with that acre. 5.0 Success Criteria The Sponsor shall be responsible for assuring the ecological success of the Bank. The success of the Bank will be measured by performance standards approved by NCDENR -DWQ permits and the UMBI. The standards define the conditions under which the Bank would be judged 7 successful and provide monitoring and maintenance requirements to uncover and correct deficiencies. The bank will be considered successful if the Sponsor demonstrates to the NCDENR that the appropriate areas have been restored, established, enhanced, or preserved and the goals of the Bank have been met. After successful completion of each milestone, the sponsor shall notify the NCDENR -DWQ in writing and request the next credit release. Upon completion of construction, the Sponsor will prepare an as-built plan and submit photographs of the completed project task along with a photo location map. NCDENR -DWQ, will confirm whether or not the tasks are successfully completed for purposes of releasing credits. 6.0 Monitoring and Maintenance Plan The Sponsor agrees to perform all necessary work to monitor and maintain the TRH MB. To demonstrate compliance with the success criteria established in this BPDP and any regulatory permits the TRH MB will be monitored for a period of (five) 5 years or until all success criteria are met and credits are sold, whichever is later. The monitoring will begin at the end of the first full growing season following completion of grading and planting (i.e., if the planting is completed in spring 2014, the first monitoring event would occur in fall 2014). The Sponsor shall provide annual monitoring reports to NCDENR -DWQ on the long term success of the Bank and to identify any problems requiring corrective action by December 31" of each year. The Bank will be designed to be self - sustaining over time. However, some active management and maintenance is anticipated to ensure the long -term viability and sustainability of the Bank. The Sponsor agrees to perform all necessary work to maintain the Bank consistent with the maintenance criteria established in this BPDP, the permits and the UMBI. The Sponsor shall continue with such monitoring and maintenance activities until Bank closure. Bank closure is defined as achieving all success criteria (listed above) and after all credits have been sold. Prior to Bank closure, an acceptable third -party non -profit land steward (such as NCEEP or an appropriate Land Conservancy) will be identified and will accept and maintain the conservation easement area. Deviation from the approved maintenance plan is subject to review and written approval by NCDENR -DWQ. 7.0 Financial Assurance Prior to any credit debiting the Sponsor shall provide financial assurances, as acceptable in consultation with the NCDENR -DWQ, to ensure a high level of confidence that the Bank will be successfully completed and maintained in perpetuity. Bonding of construction will be based on 100% of total construction costs and bonding of monitoring and maintenance will be based on 100% of the total monitoring and maintenance costs. The details of these financial assurances will be provided to DWQ as soon as they are available, prior to debiting. 8.0 Buffer Mitigation Potential The Bank consists of approximately 16.8 acres of riparian buffer and/or nutrient offset restoration. Table 3 depicts acres of buffer restoration converted to Buffer Mitigation Units (BMUs). The restoration of Buffer credits associated with the Bank will follow guidelines 8 established by the NCDENR -DWQ. The Buffer restoration acreages are calculated from the OHWM up to 200' away from the Top of bank (TOB) within the conservation easement. Table 3.
