Dear Lindsay, Thank you for your prompt review comments on our MY1 Draft Monitoring Report for the Tar River Headwaters Wetland Restoration (TRHWR) site. Responses to your review comments are provided below: • Table of Contents, Page 8, and actual table heading: update Table 4 to be titled 'Project Attributes' Response: Done • Revise all dates in the text to include full month (Example: do not write Dec, write out December). Response: Done • Please remove two references to the contracted area of wetland mitigation. This is not relevant to the report. Response: Done • Section 1.1: Project Setting and Pre -Restoration Conditions- Mogensen can use previously reviewed and approved verbiage to minimize review and comment. Generally, there should not be new verbiage developed in MY1 describing pre -site conditions at this point in the project. The entire section 1 may be replaced with section 1.1, 1.2, and 1.3 from the MYO report if the provider elects to avoid review of new information (suggestion, not requirement). Response: Text replaced with MYO report text Paragraph two section 1.1, use of the word "apparently." Was the site an upland flat headwater or not? Remove word or remove sentence. Redoximorphic soil conditions are not enough to justify the assertion this classification. Response: Text replaced with MYO report text Paragraph four section 1.1. There are statements in here that are not necessarily accurate. For instance, the pre-treatment gauge data did not provide any justification for the USACE wetland Pre -JD, please separate those items. Add the word 'acres' after 1.12. The last sentence of this paragraph, redox is only one hydric soil indicator. Please revise to state only that it was not hydric, rather than speculate on how redox played into the soil evaluation. Response: Text replaced with MYO report text Section 1.3. Mitigation Approach and Expected Improvements. Update title to just 'Mitigation Approach.' A suggestion may be to replace entire section 1.3 with a past -tense section 1.4 of the MYO report. The mitigation approach should not include detailed construction information as that is available in the As -Built report, this is more of an overview of the approach here, condensing is advised. Response: Text mostly replaced with MYO report text, revised to past tense. Kept one new sentence from the draft report, explaining why effect of ditches is significant despite shallow depths. Environmental Field Studies ■ Wetland & Stream Delineation ■ 404-401 Permits ■ Mitigation Plans & Banking MOGENSEN MITIGATION INC. Current Conditions summary: Paragraph four: Mogensen doesn't have to use 'only' as an adverb to describe gauge success. In lieu of 'only four gauges,' suggest saying 'four gauges.' Response: Done Current Conditions Last (5th) paragraph: there is currently no adjustment for soil physical properties in the hydrology standard. This is an interesting discussion on how soil redox or other hydric soil indicators may present in soils with higher water holding capacity or clay content through capillary action, but this is not an accepted indicator for meeting hydrologic standard. DMS suggests that if Mogensen feels that current methods of measuring hydrologic saturation are inadequate, then it should be discussed at an IRT meeting rather than in a project -specific monitoring report. The hydrologic success criteria for this project was proposed and accepted at the Mitigation Plan stage. Response: Deleted 5th (last) paragraph, and moved one sentence into 4th paragraph: "The monitoring gauges measure the free water table depth and do not account for capillary fringe saturation which often extends higher in clay soils (https://www.nccedev.ces.ncsu.edu/eleventh-annual-on-site/soil- wetness . Using the free water table depth as a conservative measure of ..." 3.0 Monitoring Methods: if you are going to include this in the MY1 report, please put it before the Current Conditions (2.0) section. Another idea is to remove this section, and update table in goals under the 'Monitoring Methods' column to show number of monitoring features (i.e. vegetation plots and gauges) and to include discussion of growing season dates in the Current Conditions section. Response: Moved Monitoring Methods to Section 2 and Current Conditions to Section 3. CCPV: Please show which gauges on the CCPV that are meeting and not meeting (could show separate as meeting, not meeting and N/A if you'd like). Response: Gauges on the CCPV figure have been color - coded to show which are meeting criteria, not meeting, or not applicable (non-credit area). With respect to the vegetation plot data, there are some issues with planted stems showing in MY1 that were not recorded in MYO. Review specifically the water oak, willow oak on plots 24 and 25. Is this just a case of misidentification at MYO? Please provide clarification. Response: Yes, dormant (leafless) seedlings of oaks, birch vs musclewood, and blackgum vs persimmon were in some cases misidentified during the MYO survey, and corrected in MY1. There were also a few stems overlooked in MYO that we found in MY1. Hydrology graphs, these are fine for MY1, but in the future it is beneficial to show where on the graphs (during what time of the year) that the gauges are meeting success and the number of days. This will help justify if hydrology is being attained through antecedent rain conditions or through rainfall driven events. Please consider this in the future. Response: Gauge graphs in future monitoring reports will include the start, end, and duration of the longest saturation period for each gauge. Please provide written response to these comments. After the update is approved, please provide 3 hard copies and a digital file. Thanks for your work. Response: Upon your approval of these responses and accompanying 2nd draft report PDF, we will mail the final printed copies and support files on CD.

Project Background 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 a ditch and intermittent stream connecting the TRHWR site to the adjacent Tar River Headwaters Riparian Buffer and Nutrient Offset Mitigation Bank project. Both projects are 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 -Restoration Conditions The TRHWR site was cleared and ditched for pasture use in the 1940s according to the owner, and was used for grazing cattle until January 2017 when the conservation easement fence was installed. 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. Remnant native trees left for shade, hydrophytic groundcover plants mixed among the pasture grasses, and plant species recorded in adjacent natural forests (on the same soil mapping unit) provided data for the planting plan. The project 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. 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. Restoration activities including tree planting, surface flow dispersal, 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. 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. 1.3. Mitigation Goals and Performance Criteria The subject watershed HUC #03020101-0102 is designated by NCDEQ as a Targeted Local Watershed (TLW) for water quality improvement projects, and the Tar River reach within and downstream of this local HUC is recognized as a Significant Natural Heritage Area (SNHA) for its high diversity of aquatic life including protected species of river mussels and fishes. The TRHWR project is intended to support Tar River Headwaters Wetland Restoration Site #97071 MY -1 (2017) Annual Monitoring Report Person County — Tar -Pam HUC 03020101 Mogensen Mitigation Inc. MMI these TLW and SNHA designations by improving water quality and habitat on the property and downstream. Specific project goals and objectives as identified in the TRHWR Final Mitigation Plan (December 2016) 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 -1 (2017) Annual Monitoring Report Mogensen Mitigation Inc. MMI 1.4. Mitigation Approach Prior to restoration, the TRHWR project area contained 6.53 acres of former riparian wetland (ditched and drained, grazed pasture) with redoximorphic soil characteristics indicating hydric soils, but lacking adequate wetland hydrology based on groundwater gauge data and field observations during 2015-2016. Although the drainage ditches are shallow, they have effectively reduced water retention across much of the site over the past 70 years due to the slow infiltration rate, rapid runoff, and shallow hardpan in these soils. The project will re-establish jurisdictional wetlands in this area by plugging the drainage ditches to increase rainfall retention and dispersal, 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. 2.0. Monitoring Methods Vegetation plots are monitored annually in accordance with current DMS monitoring guidance (June 2017). The nine installed CVS 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 twelve onsite groundwater monitoring gauges and one offsite reference wetland gauge are downloaded and maintained at least quarterly. Gauge data in the mitigation credit areas are plotted and evaluated for success based on the mitigation plan performance standard of continuous saturation within 12 inches of the ground surface for 10 percent of the growing season. Growing season based on air temperature at a weather station east of Roxboro is from March 28 to November 3, which is 221 days (from USDA WETS table). MMI installed a dual -probe soil temperature logger near the middle of the TRHWR site (beside GW -H) in late January 2017. Soil temperature on the site remained above 41 F at both 10 -inch and 20 -inch depths throughout February and March 2017. The lowest temperatures recorded were 42.7 F at 10 inches and 45.4 F at 20 inches. Based on soil temperatures remaining above the USDA -designated temperature for plant physiological activity, March 1 will be used as the start of the growing season, based on field discussions with DMS and USACE. The revised growing season length is thus 248 days, and the groundwater hydrology success criterion is 25 days The conservation easement perimeter fence and ditch plug integrity will be monitored visually and documented with photo points. Tar River Headwaters Wetland Restoration Site #97071 MY -1 (2017) Annual Monitoring Report Person County — Tar -Pam HUC 03020101 Mogensen Mitigation Inc. MMI 3.0. Current Conditions Summary MMI scientists made several post -construction visits to the TRHWR site between March and November 2017 to collect gauge data and evaluate the condition of the ditches, plugs, and planted trees. The CVS vegetation plot data collection was performed in early October. Eight of the nine CVS plots had 8 to 11 surviving planted stems and met success criteria. One plot (VP -21) had only five surviving planted stems and failed the criteria. Outside of the CVS plots, planted stem survival looks generally good throughout the site, with roughly ten percent apparent mortality. Leader die -back is common on many of the taller seedlings, especially on tulip poplar and river birch, but most of the trees exhibiting leader die -back also had one to several vigorous basal sprouts. Some of the trees appearing as "dead" in October may also resprout in 2018. No "low woody density" areas or "invasive exotic" areas were designated this year. Groundcover vegetation is excellent throughout, with both treated areas (non -wetland and drained wetland) and non -treated areas (existing wetland) showing dense and diverse herbaceous cover. All ditch plugs appear to be stable and performing as designed, despite 5 to 6 inches of rainfall over a 3 -day period in mid-April. Survival of planted trees, livestakes, and herbaceous cover on the plug slopes and tops appears to be providing adequate erosion protection during this first season when problems are most likely to occur. Ponding behind all of the ditch plugs was evident within a few days after construction, and dispersal of surface water from the ditches into the surrounding restoration areas was observed following large rainfall events in April and May. Eleven groundwater gauges were installed throughout the TRHWR site during February to March 2016 to collect hydrology data for use in project design, establishing current wetland jurisdiction areas, 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. Some gauges were later relocated during project construction to provide better representation of expected hydrologic results of the project, and one additional gauge was added. The 12 current groundwater gauges (A through L) on the project site are roughly arranged in four transects perpendicular to the main ditch, as recommended by mitigation plan reviewers during field meetings (Figure 2). Three gauges (A, H and J) are within existing wetland rehabilitation areas, seven gauges (D, E, F, G, I, L, and K) are within the drained wetland reestablishment areas, and two gauges (B and C) are downslope from ditch plug #4 in areas not expected to generate wetland credits. Wetland hydrology success for the TRHWR site is based on shallow saturation within 12 inches of the ground surface for 10% of the 248 -day growing season (March 1 to November 3). The monitoring gauges measure the free water table depth and do not account for capillary fringe saturation which often extends higher in clay soils (https://www.nccedev.ces.ncsu.edu/eleventh-annual-on-site/soil-wetness/). Using the free water table depth as a conservative measure of saturation depth, four gauges in the project area (C, E, H, and L) and the off-site reference gauge met the 10% criterion. The other eight gauges had extensive periods of shallow saturation ranging from 63 to 95 total days (25% to 38% of the growing season), but they also had occasional gaps of one or more days when the water table dropped lower than 12 inches. The maximum consecutive day durations for these eight non -attaining wells ranged from 10 to 17 days (4 to 7%). This pattern of water table fluctuation may be typical for certain headwater wetlands with small watersheds, perched hydrology, and dense soils with low infiltration. Two of the three gauges within the Tar River Headwaters Wetland Restoration Site #97071 MY -1 (2017) Annual Monitoring Report Person County — Tar -Pam HUC 03020101 Mogensen Mitigation Inc. MMI existing wetland (rehabilitation) areas did not meet the 10% criterion. Unusually low rainfall during February and March may also have been a factor in these results. 4.0.
