(Wildlands) has reviewed Division of Mitigation Services' (DMS) comments from the Draft Monitoring Year 0 (MYO) Report for the Oak Hill Dairy Mitigation Site. The report has been updated to reflect those comments. Wildlands responses to DMS's comments are noted below. DMS Comments, Matthew Reid: 1. Please add "Date of Issue: September 6, 2018" following RFP number on title page. Wildlands Response: Title page has been updated to include RFP date of issue. 2. Table of Contents: A set of coordinates is accidently shown under 1.3 Project Attributes. Please revise for final. Wildlands Response: Wildlands has removed the set of coordinates from the table of contents. 3. CCPV: Recommend labeling BMP1 and BMP2. Wildlands Response: BMP labels are now shown on CCPV maps. 4. Photos of BMP1 and BMP2 show a considerable amount of ponded water. Does WEI expect the BMPs to hold water year-round or dry seasonally? Wildlands Response: Wildlands expects water levels for BMP1 to drawn down when vegetation becomes established and dry -out during the drier months from late spring to early fall. BMP2 should also draw down when vegetation becomes established and during drier months; however, it will likely continue to hold a shallow pond of water especially during monitoring years or months experiencing greater than average rainfall. Wildlands will continue to monitor, and remedial action will be initiated if it is deemed necessary. 5. 3.2 Vegetation Areas of Concern: WEI has identified and treated several of the most concerning invasive species prior to and during the construction process. Please continue aggressively treating the kudzu, knotweed, bamboo and marsh dewflower as new populations are observed on the site. Also, please note on future CCPV maps the locations of invasives and where treatment occurs. Wildlands Response: Invasive species presence will continue to be monitored, treated, and documented in future monitoring reports. 6. Several areas were not planted with bare roots due to depth of standing water. Does WEI intend to plant these areas at a later date? Wildlands Response: Wildlands does not anticipate the installation of bare roots in these areas in the future. The areas that were not planted with bare roots due to standing water were planted with live stakes of species tolerant to inundation. Wildlands did not anticipate that these wetland areas would hold water, so these areas were not separated from the remainder of the wetland planting areas during the design phase of the project. However, after construction was complete, it was more evident that these areas may remain inundated or be inundated for long periods of time. Therefore, to increase survival and establishment of woody vegetation in these areas, Wildlands decided to use live stakes rather than bare roots in the inundated areas and based this judgement on past project experience on sites with similar site conditions and professional experience. 7. Sheet 1.14: Pools on UT2 profile are shown and noted as being filled with sediment. WEI expects the pools to adjust as vegetation becomes established. Please provide an update in MY1 regarding the UT2 stream conditions. Note that UT2 is not a credited reach. Wildlands Response: A brief summation of UT2 stream conditions will be included in MY1. As requested, Wildlands has included one hard copy of the revised/updated Baseline Monitoring Document and Record Drawings and has placed the DMS comment letter and our response letter after the report's cover page. A full final electronic copy of the report and support files are included on a USB drive. Please let me know if you have any questions.

Visually inspect the perimeter of the Site to ensure no easement encroachment is occurring. No easement encroachments. 1.3 Project Attributes The project is bordered by residential properties and an active dairy farm comprised of cattle pastures, an outdoor feeding area, and row crops. Based on historic aerials from 1950 to 2016, the streams existed in their same location for over 60 years. Agricultural use of the land was consistent during this period as well. Several alterations to the Site visible from historical aerial photography were the addition of the large pond in northeast corner of the Site between 1964 and 1973, and the addition of the no - discharge waste lagoon south of the large pond between 2006 and 2009. Additionally, most structures were built between 1964 and 1976 with the two large feed barns being built within the last 15 years. The Site, based on aerial photography, has a history of ditching, field grading, and stream channelization which increased drainage effects and impaired wetland hydrology.

Species replacements and planting density adjustments were made due to availability of the species at the time of planting. All species replacements were approved species or alternate species within the Final Mitigation Plan's planting list (Wildlands, 2021), so no approval for the inclusion of the species is needed. Open Buffer Planting Zone • Tag alder (Alnus serrulata) was replaced by elderberry (Sambucus canadensis). • Northern red oak (Quercus rubra), slippery elm (Ulmus rubra), and sweetshrub (Calycanthus floridus) were added at densities of 5%, 1% and 1%, respectively. • The stem density of persimmon (Diospyros virginiana) bare roots was increased from 5% to 6%. Wetland Planting Zone • Tag alder was reduced from 5% to 1%. • Silky dogwood (Cornus amomum) was added at a density of 1%. • Silky willow (Salix sericea) was added at a density of 2%. • Live stakes of black willow (Salix nigra) were added at a density of 1%. Partially Vegetated Buffer Zone • Stem densities for American hornbeam (Carpinus caroliniana), strawberry bush (Euonymus americana), pawpaw (Asima triloba), and American beech (Fagus grandifolia) were increased from 10% to 14%. • Densities for slippery elm, witch hazel (Hamamelis virginiana), , sweetshrub, and flowering dogwood (Cornus florida) were decreased from 10% to 7%. • Densities for spicebush (Lindera benzoin) and northern red oak were reduced from 10% to 8%. Planting Plan • Sheets 3.3— 3.5 — No bare roots were planted due to the depth of standing water. 2.1.14 Fencing Plan • UT1 REACH 2 — FENCE LINE ADJUSTED TO RUN CLOSER TO TOE OF SLOPE • OAK HILL CREEK REACH 1 & 2 — FENCE LINE MOVED TO TOP OF SLOPE 2.1.15 Monitoring Components Installed monitoring devices and plot locations closely mimic the locations of those proposed in the Site's Mitigation Plan. Minor deviations from these locations were made when professional judgement deemed them necessary to better represent as -built field conditions or when installation of the device in the proposed location was not physically feasible. Vegetation Monitoring Plots • Permanent Vegetation Plot (VP1) was moved from the right side of UT1A to the left side of UT1A. • VP2 was moved the left side on UT1 Reach 1 to the right side of UT1 Reach 1. • Mobile Vegetation Plot 5 (MVPS) was moved from the left side of Oak Hill Creek Reach 3 to the left floodplain of UT1 Reach 2 near the confluence of Oak Hill Creek Reach 3. The previous location for this mobile vegetation plot was inadvertently located within the extents of BMP2. Oak Hill Dairy Mitigation Site 41, Monitoring Year 0 Annual Report - FINAL 2-11 Cross -sections • Cross-section 3 (XS3) was moved upstream on UT1 Reach 1 due to a large diameter tree within the floodplain. Section 3: Monitoring Year 0 Data Assessment Annual monitoring and site visits were conducted during MYO to assess the condition of the project. The vegetation and stream success criteria for the Site follow the approved success criteria presented in the Mitigation Plan (Wildlands, 2021). Performance criteria for vegetation, stream, and hydrologic assessment are located in Section 1.2 Table 3: Goals, Performance Criteria, and Functional Improvements. The first annual monitoring assessment (MY1) will be completed in the fall of 2022, at least 6 months after the MYO assessment. The Site will be monitored for a total of seven years, with the final monitoring activities scheduled for 2028. 3.1 Vegetative Assessment The MYO vegetative survey was completed in February 2022. Vegetation monitoring resulted in a stem density range of 445 to 688 planted stems per acre which is well above the interim requirement of 320 stems per acre required at MY3. Average stem density was 603 planted stems per acre. All 13 permanent and 6 mobile vegetation plots met the interim success criteria and are on track to meet the final success criteria required for MY7. Herbaceous vegetation is establishing itself across the site. Refer to Appendix A for Vegetation Plot Photographs and the Vegetation Condition Assessment Table and Appendix B for Vegetation Plot Data. 3.2 Vegetation Areas of Concern Vegetation management and herbicide applications were implemented prior and during construction to prevent the spread of invasive species that could compete with planted native species. A dense stand of bamboo (Phyllostachys aurea) was mechanically removed along UT1A during construction. Kudzu (Pueraria montana) was removed along UT1B. Other areas of Chinese privet (Lingustrum sinese), Japanese privet (Lonicera japonica), Japanese knotweed (Polgonum cuspidatum), English Ivy (Hendra helix), marsh dewflower (Murdannia keisak), and multiflora rose (Rosa multiflora), were treated on the Site during construction. Invasive species will continue to be monitored, mapped, and controlled as necessary throughout the monitoring period. 3.3 Stream Assessment Morphological surveys for MYO were conducted from February 2022 to March 2022. All streams within the Site are stable and functioning as designed. All 14 cross sections at the Site show little to no change from design in the bankfull area and width -to -depth ratio, and bank height ratios are less than 1.2. Reachwide and riffle 100-count substrate sampling were conducted during baseline condition assessment to classify the reach and characterize the riffle pavement. Riffles along most reaches have a median particle size classification of medium gravel to small cobble. Based on a DMS Technical Workgroup memo from 10/19/21 and concurrence received on 10/27/2021 from the DMS project manager for the Site, pebble counts will not be conducted during the remaining monitoring years unless requested by the IRT or deemed necessary by best professional judgement. Refer to Appendix A for the Visual Stream Morphology Stability Assessment Table and Stream Photographs. Refer to Appendix C for Stream Geomorphology Data. W Oak Hill Dairy Mitigation Site Monitoring Year 0 Annual Report - FINAL 3-12 3.4 Stream Areas of Concern Inspection of stream structures and banks did not identify any stream areas of concern, indicating that the stream is preforming as designed. The Site will continue to be monitored and any issues will be mapped and reported throughout the monitoring period. 3.5 Hydrology Assessment Crest Gages (CG) were installed on Oak Hill Creek, UT1, and UT1A to monitor bankfull events. Hydrologic data will be collected and reported during MY1. 3.6 Wetland Assessment Eleven groundwater gages were installed before the start of the growing season in wetland creation, rehabilitation, and re-establishment areas to determine wetland hydrology success across different restoration levels. Soil profile descriptions and groundwater gage photographs were taken during installation and are located in Appendix A. Groundwater gage data will be collected and reported during MY1. 3.7 Adaptive Management Plan Site maintenance and adaptive measurement implementation will follow those outlined in the project's Final Mitigation Plan (Wildlands, 2021). No adaptive management plans are needed at this time. 3.8 Monitoring Year 0 Summary Overall, the Site looks good, is performing as intended, and is on track to meet success criteria. All vegetation plots are exceeding the MY3 interim requirement of 320 planted stems per acre, and all streams within the Site are stable and meeting project goals. Herbaceous vegetation is establishing itself across the site. Invasive species were treated and/or physically removed across the Site prior to and during construction and will continued to be assessed throughout the monitoring years. Summary information and data related to the performance of various project and monitoring elements can be found in the tables and figures in the report appendices. All raw data supporting the tables and figures in the appendices are available from DMS upon request. W Oak Hill Dairy Mitigation Site Monitoring Year 0 Annual Report - FINAL 3-13 Section 4: METHODOLOGY Annual monitoring will consist of collecting morphologic, vegetative, and hydrologic data to assess project success based on the goals outlined in the Site's Mitigation Plan (Wildlands, 2021). Monitoring requirements will follow guidelines outlined in the NC IRT Stream and Wetland Mitigation Guidance Update (2016). Installed monitoring devices and plot locations closely mimic the locations of those proposed in the Site's Mitigation Plan. Deviations from these locations were made when professional judgement deemed them necessary to better represent as -built field conditions or when installation of the device in the proposed location was not physically feasible. Geomorphic data was collected following the standards outlined in The Stream Channel Reference Site: An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in Stream Restoration: A Natural Channel Design Handbook (Doll et al., 2003). All Integrated Current Condition Mapping was collected by either a professional licensed surveyor or an Arrow 100' Submeter GNSS Receiver and processed using ArcPro. Crest gages, using automated pressure transducers, were installed in riffle cross -sections to monitor stream hydrology throughout the year. Groundwater gages were installed using guidance from the USACE's Technical Standard for Water -Table Monitoring of Potential Wetland Sites (2005). Stream hydrology and vegetation monitoring protocols followed the Wilmington District Stream and Wetland Compensatory Mitigation Update (NCIRT, 2016). Vegetation installation data collection follow the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008); however, vegetation data processing follows the NC DMS Vegetation Data Entry Tool and Vegetation Plot Data Table (NCDMS, 2020).

Agreement was reached between all attending parties that pebble count data will not be required during the monitoring period for all future projects. Sediment data and particle distribution will still be required for the mitigation plan as part of the proposed design explanation and justification. Pebble counts and/or particle distributions currently being conducted by providers for annual monitoring may be discontinued at the discretion of the DMS project manager. If particle distribution was listed as a performance standard in the project mitigation plan, the provider is required to communicate the intent to cease data collection with the DMS project manager. The absence of pebble count data in future monitoring reports where pebble count data was listed as part of monitoring in the mitigation plan must be documented in the monitoring report. The September 29, 2021 Technical Work Group meeting may be cited as the source of the new policy. The IRT reserves the right to request pebble count data/particle distributions if deemed necessary during the monitoring period.

Moving forward, are you going to allow us to stop doing them on your projects? If so, will DBB projects be treated the same? Please let me know. Thank you!
