PO Box 690429 Charlotte, NC 28227 ROY COOPER Governor MICHAEL REGAN Secretary Subject: Draft MYO Review Tar River Headwaters Project ID #97071, DMS Contract #0006746 Dear Rich, Please make the following revisions to the Tar River Headwaters Wetland Restoration Site MYO report: • 1 will re -iterate the need to reread your contracted deliverables before submitting. The As -Built Monitoring Report Template- Feb 2014 should have provided a template and guideline for this As -Built report. Many of these required sections were absent, present in the wrong formats; or the report contained extraneous information. This is the link to your template: https://ncdenr.s3.amazonaws.com/s3fs- public/Mitigation%20Services/Document%20Management%201-ibrary/Guidance%20and %20Template%2ODocuments/As- built%20Base Iine%20Monitorina%20Reaort%20Temblate%20-%2OFeb%202014.Ddf • Much of the text submitted was from the original mitigation plan or new, for which DMS had multiple iterations of comments and changes. It is advisable that Mogenson use previously approved text to describe conditions from the Mitigation Plan rather than re- submit materials that were previously unacceptable. Furthermore, there are multiple and regular inconsistencies between the verbiage between the Mitigation Plan and this As -Built document. In the interest of staff time and effort, DMS urges Mogenson to develop a QA/QC process that will eliminate multiple iterations of review and that there is a better effort to review requirements in the contract and template documents. • Please use examples from our project document pages to show what a typical As -built product looks like. A good example of a similar project can be found here: https://ncdenr.s3.amazonaws.com/s3fs- public/Mitigation%20Services/Document%20Management%201-ibrary/Protects/BearBas in 95362 MYO 2015.Ddf State of North Carolina I Environmental Quality I Mitigation Services 1652 Mail Service Center 1217 W. Jones Street, Suite 3000 I Raleigh, NC 27609-1652 919 707 8976 T • Provide As -built survey drawings consistent with the contract, to include red -line topographic contours in the areas of fill in the proposed wetland areas overlaid on the original survey. See the appendix of the project above. The survey submitted does not contain information on the filled areas and their elevation tie-ins. Remove labels of "filled in areas." • Provide digital files of the as -built survey consistent with the contract, to include full Auto Cad (.dwg) files • Provide digital files that include ArcMap GIS shape files of vegetation plots, credit areas, conservation easement, and point files of the monitoring gauges and soil temperature locations. Please see attached 'digital drawing Guidelines' for information. • Submit excel file that contains tables with standard formats per contract. Use these excel tables to paste and replace all tables in the document. Here is a link to all our template documents, and an excel example sheet is also attached: http://deg.nc.gov/about/divisions/mitigation-services/dms-vendors/rfp-forms- templates and the excel document template for this RFP can be found here: http://Portal.ncdenr.org/c/document library/get file?p I id=60409&folderld=2650974 8&name=DLFE-118739.xls (or use the one attached to your email) • Provide CVS access file with vegetation information for all plots (including riparian buffer plots). Sectionl.l and 1.2 • Replace section 1.1 and 1.2 with the first four paragraphs in the previously approved Mitigation Plan. Section 1.3 • Remove the first part of the paragraph and start that section with the sentence, "Specific Project Goals..." • Add section regarding performance standards (can paste from Mitigation Plan, page 20, section 7.2). Section 1.4 Remove sentence "The remaining 1.27 acres... credits." Remove reference to (MMI. 2016), you can just say that the assets match the Mitigation Plan without using a formal citation. Section 1.5 • Remove last sentence as it is N/A to report. • Describe how groundwater gauges were installed ("per mitigation plan review suggestions", "as transects", etc.) • Describe how vegetation plots were installed (i.e. "installed randomly" or "at representative locations to show planting densities"). • Describe type of fence installed. • Replace "sprayed with Glyphosate," with the following, "Site preparation that occurred on-site included soil aeration and chemical control for grasses and weeds." • Reference planting table of species. Insert number of trees of each species planted. • If you are going to describe ditch plugs by their number, then these numbers need to be shown on a map. • As an option, and instead of breaking out everything by section, you could just state, "Construction methods included aeration, site preparation, planting, and fencing." • In the last paragraph, why do you break out and describe the 1.27 -acre area as this information contains nothing that relates to construction or mitigation design approach? Please explain or remove. • Merge section 1.5 with section 1.6. Change title to 'As -Built' • Add information about the clay plugs ... how long were these typically, and what did the fill material consist of? Did you meet plasticity specs? Section 1.6 • Remove word "about" from description of tree density. The word "average" already explains that the numbers are "about." • Replace "invasive weed" with "invasive species." Do not speculate on what "might" happen in the future as it does not pertain to an as -built report. • Was there temporary and permanent seed applied, was the area limed and fertilized? What were the species and rates? If not, then this is a deviation from the Mitigation Plan and should be noted as to why. Additional • There should be an additional section that includes your Monitoring Plan. Can include copy paste from section 7.1 of Page 19 of your Mitigation Plan. Tables • Replace all tables with standard excel file tables (see links above, and file included) • Remove comment under Table 1 (***) • Table 2. See excel table for standard timeline items. It is not necessary to reference dates of JD, Technical Proposal, Mitigation Banking Instrument, or drafts. December 2016 is the date for the final mitigation plan for this. • Table 4. Project area should be equal to the easement size. • All of the regulatory considerations are N/A for this project. The JD is only relevant to justify the rehabilitation. • Table 5. Remove and replace with CVS export of three plots, and summary info (examples in the link above). • Include number of each of the trees planted in planting list, and common name. This should be in a table format. • It appears that there were at least 3 additions or substitutions of trees from those described in the planting plan. Any deviations from planting should be noted in the As - built report along with the reason. CCPV: This should only include wetland project components. Can't distinguish between credit and easement, etc and there are many things labeled on this map that are unnecessary. Consult digital guidance and revise. Pictures. Please indicate (in the text) which direction and which pipe that pictures were taken for future contiguity. Photo points should be labeled on the CCPV and included in your digital submission. After these updates are made, please provide an updated digital draft for my consideration (you can use WeTransfer). Due to the large number of required edits, please re -submit the files, along with digital files for secondary review. Thanks for your work, r /Lt . Lindsay Crocker, DMS Table of Contents 1.0.

MMI 1.0. Project Summary 1.1. Project Location and Setting The Tar River Headwaters Wetland Restoration Site (TRHWR) is a full -delivery wetland mitigation project located in eastern Person County, between Roxboro and Oxford, North Carolina, within the Piedmont Physiographic Province (Figure 1). The easement comprises 9.98 acres, most of which is drained and degraded wetlands or former wetlands with hydric soil indicators. The remaining areas include non -hydric soils, drainage ditches, and a 570 -foot long riparian corridor along an intermittent stream connecting the TRHWR site to the adjacent Tar River Headwaters Riparian Buffer and Nutrient Offset Mitigation Bank project. Both projects are designed and implemented by Mogensen Mitigation, Inc. (MMI), and are located on a 228 -acre farm owned by Roy and Joyce Huff, in the Tar -Pamlico River Basin 12 -digit HUC # 03020101-0102. The Huff Farm property is located at 333 Bunnie Huff Road, Oxford NC 27565. The access road into the TRHWR site is at Latitude = 36.3913, Longitude = -78.8171. 1.2. Pre -Construction Site Conditions The TRHWR site was cleared and ditched for pasture use in the 1940s according to the owner, and was until recently used for grazing cattle. The project involves plugging drainage ditches to restore wetland hydrology, fencing to exclude livestock, and planting native trees and shrubs to restore a Headwater Forest wetland ecosystem similar to what occurred prior to site clearing and drainage. The remnant mature trees left for shade, hydrophytic groundcover plants mixed among the pasture grasses, and plant species recorded in adjacent forests (on the same soil mapping unit) provide data for the planting plan. The proposed work will restore approximately 7.65 acres of headwater riparian wetland (6.53 acres reestablishment plus 1.12 acres rehabilitation) and will generate an estimated 7.28 or more riparian wetland mitigation credits (RWMC), exceeding the 5.0 RWMC requested by the NC Division of Mitigation Services (DMS) in RFP # 16-006476. Approximately 1.27 acres with non -hydric soils in the southeast corner of the mitigation site will also be reforested, and a 100 -foot wide by 570 -ft long riparian corridor (1.06 acre) extending southeastward along the ditch will connect the TRHWR site to MMI's adjacent stream restoration and nutrient buffer bank project to the south. Total acreage of the wetland mitigation site and riparian connector is 9.98 acres. The proposed wetland restoration and cattle exclusion will reduce soil erosion and nutrient -enriched runoff from adjacent pasture and cropland within its watershed, and help retain agricultural chemicals used on these lands. Erosion will be significantly reduced by buffering with native tree plantings. It is expected to improve water quality and habitat in the receiving tributary and reduce fine sediment loading which will enhance the overall watershed particularly in the adjacent stream and nutrient mitigation bank.

Mitigation Goals and Objectives Specific project GOALS and corresponding OBJECTIVES include: GOALS: • Restore the natural jurisdictional wetland hydro -period to five or more acres of forested wetland within a nine -acre site; • Restore forested wetland habitat and improve habitat connectivity between Denny Store Gabbro Forest (NHP Natural Heritage Area) to the north and the Tar River tributaries; • Buffer storm water runoff from fecal and other cattle -related pollutants and fertilizer. OBJECTIVES: • Plug existing ditches and create sheet flows throughout the site. Aerate soils to reduce compaction, improve infiltration, and create micro -topography to retain surface flows; • Preserve the remnant mature Swamp White Oaks (a regionally rare species) for seed source. Plant appropriate native hardwood trees at a sufficient frequency to establish a diverse bottomland wetland forest. Treat and/or remove invasive species which may cause problems for site restoration, including Chinese privet and multi -flora rose; • Install fencing to exclude cattle and establish a conservation easement to provide permanent protection on the site.

Tar River Headwaters Wetland Restoration Site #97071 Person County — Tar -Pam HUC 03020101 4 MY -0 (2017) As -Built Baseline Report Mogensen Mitigation Inc. MMI 1.4. Mitigation Components and Attributes The TRHWR project area contains 6.53 acres of former riparian wetland (ditched and drained, grazed pasture) that has redoximorphic soil characteristics indicating hydric soils, but no longer has adequate wetland hydrology based on groundwater gauge data and field observations during 2015-2016. The drainage ditches were constructed in the 1940s, according to the owner. The project will re-establish jurisdictional wetlands in this area by plugging the drainage ditches to restore wetland hydrology, fencing out livestock, controlling invasive species, and planting suitable native tree species. These 6.53 acres of wetland restoration will generate riparian wetland credits at 1:1 ratio, yielding 6.53 WMU. Another 1.12 acres in the TRHWR project area has been less effectively drained by the ditches, and still has sufficient hydrology to meet jurisdictional wetland criteria, based on groundwater gauge data and field observations during 2015-2016. The project will rehabilitate these areas of degraded jurisdictional wetland (grazed pasture with reduced hydrology) by plugging ditches to increase hydrology, fencing out livestock, and planting suitable native tree species. These 1.12 acres of wetland rehabilitation will generate riparian wetland credits at 1.5:1 ratio, yielding 0.75 WMU. TRHWR project components and mitigations assets are summarized in Table 1, matching the proposed assets in the Mitigation Plan. 1.5. Construction and As -Built Conditions Eleven groundwater gauges were installed throughout the site in Feb -Mar 2016 to collect hydrology data for use in project design, easement boundary selection, water budgeting, and credit determination. A reference wetland gauge was installed 1,500 ft northeast of the project easement, within the same soil mapping unit on the Huff property. Some gauges were later relocated during project implementation to provide better representation of expected hydrologic impacts of the project, and one additional gauge was added. As -built gauge locations (Feb 2017) are roughly arranged in transects perpendicular to the main ditch, as recommended by mitigation plan reviewers during field meetings (Figure 2). Ten gauges are within the proposed creditable reestablishment and rehabilitation areas, and two gauges are down -gradient from ditch plug #4 in the area of non -hydric soils, not expected to generate wetland credits. A series of six ditch plugs were constructed to retain rainfall and disperse runoff on the site. Five plugs along the main north -south ditch include four in the TRHWR area and one downstream in the connector area in the southeastern portion of the easement (Figure 2). The sixth plug is on the eastern side ditch in the TRHWR area. Ditch bed segments to be filled were excavated six inches to remove loose material and plants, to ensure good contact between the fill material and underlying clay. Clay for the plugs was excavated from the pasture area south of the easement fence, and mixed with sand to achieve liquid limit and plasticity characteristics as recommended in the mitigation plan. To further enhance ditch plug stability, the contractor increased the length of plugs on the main ditch, constructing five long plugs (each plug 65 to 118 ft long) rather than the seven short plugs shown in the mitigation plan. The proposed cluster of plugs where three ditches converge were merged into one large plug (plug #4). The centerline of each plug is approximately 2 inches below the adjacent ground surface (old ditch banks), per the mitigation plan. The elevation drop from the toe of each plug downstream to the crest of the next plug in the wetland restoration area is 1 to 2 feet (Figures 3 and 4).

Signature Print Name:* Lindsay Crocker Signature:* Date 02/15/2019 In the drained areas, soil aeration and herbicide application for pasture grasses and other invasive species were conducted prior to planting. Soil amendments and seeding were applied as specified in the mitigation plan. Existing wetlands, ditch banks, and areas surrounding large native trees were not sprayed. The wetland rehabilitation and reestablishment areas were planted with eleven species of native trees selected based on nearby headwater wetland forests, published natural community descriptions (Schafale and Weakley, 1990; LeGrand, 2007), and recommendations from the plant nursery (Table 5). A few of the oak species proposed in the mitigation plan were not available; water oak, willow oak, and persimmon were substituted. Power augers and shovels were used to dig the planting holes for the gallon -size potted trees, and a tree fertilizer pellet was added to each planting hole. Live -stakes of black willow and silky dogwood were planted on the ditch plugs and adjacent ditch banks, along with rushes and other plants excavated from the ditches prior to plugging. The easement was fenced to exclude cattle using 4 -ft high woven -wire field fence supported on 6 -inch diameter pressure -treated wooden posts (10 -ft spacing) with single -strand barbed wire on top. Nine CVS vegetation monitoring plots, each 10 x 10 meters, were installed at representative locations to show planting densities in the mitigation areas, avoiding areas shaded by large trees (Figure 2). Plot corners were marked with steel conduit pipe, and planted trees within each plot were mapped and identified following the CVS protocol (Lee et al, 2008). A soil temperature data logger was installed near the middle of the site as a supplement to climate data for assessing growing season length. Construction, fencing, spraying and seeding were completed in January 2017. The ditch segments above the plugs filled with water within the first few days after construction. The only deviation from the mitigation plan was the contractor's decision to build the ditch plugs longer than depicted in the mitigation plan, to ensure plug stability. Tree planting and vegetation plot set-up were completed in February 2017 (Tables 5 and 6). The site was relatively wet due to recent rains during planting, and many of the planting holes had standing water. The average initial planting density based on the nine CVS plots in the wetland rehabilitation and re-establishment areas is 409 trees per acre. No invasive species problem areas were noted at this time. About a dozen mature trees remain in the restoration area; none of these are within the vegetation monitoring plots. 1.6. Monitoring Plan and Performance Standards To evaluate mitigation success on the TRHWR site, vegetation monitoring plots will be monitored annually in accordance with the "Stream and Wetland Monitoring Guidelines" (February 2014). The nine installed vegetation plots, each 10 x 10 meters, represents 2.8 percent of the planted mitigation area. Vegetation monitoring will occur between September and early November, prior to the loss of leaves. The vegetation success criteria are specified in the Performance Standards above. If success criteria are not met, site maintenance and monitoring will continue until the success criteria are met. The groundwater monitoring gauges will be downloaded and maintained at least quarterly. Gauge data in the mitigation credit areas (2 gauges in rehabilitation areas, 8 gauges in re-establishment areas) will be plotted and evaluated for success based on the mitigation plan performance standard of saturation within the upper 12 inches for at least 10% of the growing season. The growing season will be determined either by soil temperature (41'F or greater at 20 inches below the soil surface) or from the USDA WETS Table data for Person County based on moderate -freeze air temperature data (March 28 to Nov 3 = 220 days).
