The project is also located in the Troublesome and Little Troublesome Creeks Local Watershed Plan (LWP). There is a wetland component to this project, however it is partially within this HUC, with the majority located outside of the watershed in a non -targeted HUC. Currently, DMS has one other project in this TLW/LWP (Little Troublesome). Little Troublesome Creeks drains to the Haw River approximately 5.5 miles downstream of the stream portion of this project. Little Troublesome Creek is identified on the NC Division of Water Resources (NCDWR) 2014 303d Impaired Waters list. It has been listed since 2000 for impaired benthic communities. Downstream of the 303d listed portion of Little Troublesome Creek (approximately 0.5 mi downstream) Little Troublesome Creek has a TMDL that was approved in 2002 to manage Fecal Coliform bacteria. The 2009 Cape Fear RBRP indicates that impacts development and point sources are degrading the creek. The Troublesome and Little Troublesome LWP indicates that Troublesome Creek suffers from significant inputs of sediment and fecal coliform, degraded riparian buffers, floodplain development and stormwater stresses. Stream channelization is also contributing to bank instability and active erosion. Stormwater management and stream restoration were the priorities of the LWP for this watershed with the aim at improving water quality, habitat and hydrology. The goals of the Little Troublesome Creek project are consistent with DMS watershed planning goals. The project increases stream stabilization and reduces sediment inputs, decreases nutrient inputs and improves habitat conditions through riparian buffer implementation and wetland restoration and improves instream habitat conditions. Project Setting and Background Summary The Little Troublesome Mitigation Site is located in Rockingham County within the Cape Fear River Basin (USGS HUC 03030002) near the town of Reidsville, North Carolina. The project consists of a Stream Site and a Wetland Site. The Stream Site is located on the southeastern side of Reidsville and consist of Little Troublesome Creek, Irvin Creek, and one unnamed tributary (UT1) to Little Troublesome Creek. At the downstream limits of the project, the drainage area is 3,245 acres (5.1 square miles). The Wetland Site is located approximately four miles southeast of the Stream Site and is also adjacent to Little Troublesome Creek. Prior to construction activities, the most significant watershed stressors identified during the technical assessment were stream bank erosion and instability. Other stressors included declining aquatic habitat, loss of forest, degraded riparian buffers, loss of wetlands, lack of urban stormwater detention, and water quality problems related to increased sediment and nutrient loadings. Because of the aforementioned stressors, the Stream Site and Wetland Site had poor water quality due to sediment pollution and poor habitat due to lack of riparian and wetland vegetation. In particular, the Stream Site lacked stable streambank vegetation despite being surrounded by mature vegetation. The Stream Site also lacked instream bed diversity and exhibited unstable geomorphic conditions. The project design approach was developed to restore and protect aquatic and riparian terrestrial habitat within the project corridor. The project provided numerous ecological benefits within the Cape Fear River Basin. While most the ecological uplift occurred at the site level, others such as pollutant removal and improved aquatic and terrestrial habitat have the potential for more far- reaching effects. Overall, the project is stable and functioning as intended and has met the vegetation, stream, hydrology, and wetland success criteria. Isolated areas of bank scour noted in previous monitoring reports have stabilized as a result of streamside vegetation in these areas. At least two bankfull events have been documented on each restoration reach over the five-year monitoring period. All groundwater gages on the Wetland Site met the success criterion during monitoring years 2 through 5. A small beaver dam was noted on Irvin Creek Reach 1 in December of 2014. This beaver dam was removed by hand and no signs of beaver have been present since. During monitoring year 3 bank scour was documented in the meander bend at STA 207+50-208+80 (Cross Section 12) on Little Troublesome Creek. Undercutting of the rootwads resulted in an area of bank scour within the meander bend. This was repaired during monitoring year 4 by lowering the rootwads and adding brush toe to fill in the voids. Geolifts were installed with brush whips and live stakes to stabilize the stream bank. Also, during monitoring year 4 kudzu and multiflora rose were spayed to control these invasive plants and keep them from spreading farther into the easement. During monitoring year 5 the stream site had a significant flow event during Hurricane Mathew, resulting in a few isolated areas of bank scour on Little Troublesome Creek and Irvin Creek. These areas were repaired in March 2017 with brush toe and soil lifts with live willow whips and sod mats. Live stakes were also supplemented along stream banks to replace damaged willows from the aforementioned beaver activity. Most of the repair work was minor and performed by hand. Heavy equipment was only used when needed to avoid causing damage to the site. Also, during monitoring year 5, kudzu, multiflora rose, and a small patch of privet were sprayed to control these invasive plants and prevent them from spreading farther into the easement. The vegetative communities at the site are flourishing and are progressing towards a natural Piedmont bottomland forest. Goals and Objectives: The following project goals and objectives were established in the Little Troublesome Creek Mitigation Plan: Primary Project Goals Project Objectives • Restored riffles within the reaches will be constructed to remain Stabilize stream dimension stable and will show little change in bankfull area, maximum depth ratio, and width -to -depth ratio over time. • Restore stream reaches so that bedform remains stable over time. • Restored riffles will remain steeper and shallower than pools. Stabilize stream pattern and profile • Restored pools will remain deep with flat water surface slopes. • Percentage of riffles and pools will not change significantly over time. • Banks will be restored so that bank height ratios remain very near to 1.0 for nearly all the stream reaches. Establish proper substrate distribution throughout the • Stream substrate to remain coarse in the riffles and finer in the stream reaches pools. • A free groundwater surface must be present within 12 inches of Establish wetland hydrology for the restored wetlands the ground surface for 7 percent of the growing season measured on consecutive days under typical precipitation conditions. • Native vegetation appropriate for the wetland and riparian buffer Restore native vegetation throughout the wetlands and zones on the site will be planted throughout. buffer zones • The planted trees will become well established and survival criteria will be met. Secondary Project Goals Project Objectives • Off -site nutrient input will be absorbed on -site by filtering flood flows through restored floodplain areas and wetlands, where Decrease nutrient and urban runoff pollutant levels flood flows can disperse through native vegetation and be captured in vernal pools. • Increased surface water residency time will provide contact treatment time and groundwater recharge potential. • Sediment input from eroding stream banks will be reduced by installing bioengineering and in -stream structures while creating a Decrease sediment input stable channel form using geomorphic design principles. • Sediment from off -site sources will be captured by deposition on restored floodplain areas where native vegetation will slow overland flow velocities. • Restored riffle/step-pool sequences where distinct points of re - aeration can occur will allow for oxygen levels to be maintained in the perennial reaches. Decrease water temperatures and increase dissolved . Creation of deep pool zones will lower temperature, helping to oxygen concentrations maintain dissolved oxygen concentrations. • Establishment and maintenance of riparian buffers will create long-term shading of the channel flow to minimize thermal heating. • In -stream habitat will be improved by creating a channel form that includes riffle and pool sequences, gravel and cobble zones Create appropriate in -stream habitat for macroinvertebrate habitat and deep pool habitat for fish. • Introduction of large woody debris, rock structures, root wads, and native stream bank vegetation will substantially increase habitat value. • Adjacent buffer areas will be restored by removing invasive vegetation and planting native vegetation. Create appropriate terrestrial habitat • These areas will be allowed to receive more regular inundating flows. • Riparian wetland areas will be restored and enhanced to provide wetland habitat. • By allowing for more overbank flooding and by increasing channel roughness, local channel velocities can be reduced. Decrease channel velocities . This will allow for less bank shear stress, formation of refuge zones during large storm events and zonal sorting of depositional material.

Recommendation and Conclusion This project is stable and functioning as intended and has met the vegetation, stream, hydrology, and wetland success criteria. The stream portion of this project provides significant uplift by stabilizing stream flow through a large and developed watershed, providing effective downstream sediment transport processes. The project's efficacy in attenuating stormwater flooding was demonstrated throughout this project with numerous and significant flooding events; structures and streams have performed effectively and demonstrated stability. Ancillary benefits from the stream restoration including vernal features and raised elevations created successful wetland fringes and contribute positively to a watershed that has noted benthic community impairments. The wetland portion of this project will provide significant uplift in the form of water quality and agricultural filtration to the watershed. DMS recommends closing this site as proposed. Contingencies None.

Standard Erosion and Sediment Control Practices Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices: a. Design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor -owned or leased borrow pits associated with the project, b. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. c. Reclamation measures and implementation must comply with the requirements of the Sedimentation Pollution Control Act and the Mining Act of 1971, d. Sufficient materials required for stabilization and/or repair of erosion control measures and stormwater routing and treatment shall be on site at all times, except for publicly funded linear transportation projects when materials can be accessed offsite in a timely manner.. e. If the project occurs in waters or watersheds classified as Primary Nursery Areas (PNA's), Trout (Tr), SA, WS-I, WS-II, High Quality (HQW), or Outstanding Resource (ORW) waters, then the sediment and erosion control requirements contained within Design Standards in Sensitive Watersheds (15A NCAC 04B .0124) supercede all other sediment and erosion control requirements. 4. No Sediment and Erosion Control Measures in Wetlands or Waters Sediment and erosion control measures should not be placed in wetlands or waters outside of the permitted impact areas without prior approval by the Division. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, design and placement of temporary erosion control measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands or stream beds or banks, adjacent to or upstream and down stream of the above structures. All sediment and erosion control devices shall be removed and the natural grade restored within two (2) months of the date that the Division of Land Resources or locally delegated program has released the project. 5. Construction Stormwater Permit NCG010000 Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General stormwater permit (NCGO10000) administered by the Division is automatically issued to the project. This General Permit allows stormwater to be discharged during land disturbing construction activities as stipulated by conditions In the permit. If your project is covered by this permit [applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self -monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at h(tp://h2o enrstate.nc.us/su/Forms Documents hfm. The North Carolina Department of Transportation (NCDOT) shall be required to be in full compliance with the conditions related to construction activities within the most recent version of their individual NPDES (NCS000250) slormwater permit. Water Quality Certification No. 3689 Water Quality Certification No. 3689 6. Construction Moratoriums and Coordination If activities must occur during periods of high biological activity (i.e. sea turtle or bird nesting), then biological monitoring may be required at the request of other state or federal agencies and coordinated with these activities. This condition can be waived through written concurrence on a case by case basis upon reasonable justification. All moratoriums on construction activities established by the NC Wildlife Resources Commission (WRC), US Fish and Wildlife Service (USFWS), NC Division of Marine Fisheries (DMF), or National Marine Fisheries Service (NMFS) to lessen impacts on trout, anadromous fish, Iarvallpost4arval fishes and crustaceans, or other aquatic species of concern shall be implemented. This condition can be waived through written concurrence on a case by case basis upon reasonable justification. Work within the twenty-five (25) designated trout counties or identified state or federal endangered or threatened species habitat shall be coordinated with the appropriate W RC, USFWS, NMFS, and/or DMF personnel. NC Wildlife Resources Commission will not object to construction of Natural Resources Conservation Service (NRCS) 'urgent and compelling' sites during the spawning period provided these projects are, to the extent appropriate and practical, constructed by: a. Using flow diversion structures such as sandbags; b. Placing large -size rock toes and filter cloth backing for stabilization sites before backfilling; and c. Excavating new channel alignments in dry areas. Construction at non, urgent and compelling' sites shall not occur during the spawning period to minimize the potential adverse effects of multiple construction activities on trout or anadromous fish resources in this stream. 7. Work In the Dry All work in or adjacent to stream waters shall be conducted in a dry work area. Approved best management practices from the most current version of the NC Sediment and Erosion Control Manual, or the NC DOT Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams, and other diversion structures shall be used to minimize excavation in flowing water. Exceptions to this condition require submittal to, and approval by, the Division. 8. Riparian Area Protection (Buffer) Rules Activities located in the protected 50-foot wide riparian areas (whether jurisdictional wetlands or not) within the Neuse, Tar -Pamlico, Randleman, Catawba (or any other basin with buffer rules), shall be limited to "uses" identified within and constructed In accordance with 15A NCAC 213 .02333 .0259, .0250 and .0243, and shall be located, designed, constructed, and maintained to have minimal disturbance to protect water quality to the maximum extent practicable through the use of best management practices. All buffer rule requirements, including diffuse flow requirements, must be met. 9. Water Suppiy Watershed Buffers The 100-foot wide (high -density development) or the 30-foot wide vegetative buffer (all other development) must be maintained adjacent to all perennial waters except for allowances as Water Quality Certification No. 3689 3 Water Quality Certification No. 3689 provided in the Water Supply Watershed Protection Rules [15A NCAC 2B .0212 through .02151. 10. If concrete is used during the construction, then a dry work area should be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be discharged to surface waters due to the potential for elevated pH and possible aquatic life/fish kills. 11. Any rip -rap shall be of such a size and density so as not to be able to be carried off by wave or current action and consist of clean rock or masonry material free of debris or toxic pollutants. Rip -rap shall not be installed in the streambed except in specific areas required for velocity control and to ensure structural integrity of bank stabilization measures. If rip -rap is to be installed within the streambed, the amount and location must be approved in writing by the Division of Land Resources and Division of Water Quality. However, rock vanes, wing deflectors, and similar structures for grade control and bank protection are acceptable. 12, If an environmental document is required under NEPA or SEPA, then this General Certification is not valid until a Finding of No Significant Impact or Record of Decision is issued by the State Clearinghouse, 13. Additional site -specific conditions may be added to the written approval attached to this Certification in order to ensure compliance with all applicable water quality and effluent standards. 14.This Certification shall expire three (3) years from the date of the approval letter from DWQ or on the same day as the corresponding Nationwide Permit. In accordance with General Statute 136-44.713, certifications issued to the NCDOT shall expire only upon expiration of the federal 404 Permit. The conditions in effect on the date of issuance of Certification for a specific project shall remain in effect for the life of the project, regardless of the expiration date of this Certification. If the construction process for approved activities will overlap the expiration and renewal date of the corresponding 404 Permit and the Corps allows for continued use of the 404 Permit, then the General Certification shall also remain in effect without requiring re -application and re -approval to use this Certification for the specific impacts already approved. 15. The applicanUpenniltee and their authorized agents shall conduct all activities in a manner consistent with State water quality standards (Including any requirements resulting from compliance with §303(d) of the Clean Water Act), and any other appropriate requirements of Stale and Federal Law. If the Division determines that such standards or laws are not being met, including failure to sustain a designated or achieved use, or that State or Federal law is being violated, or that further conditions are necessary to assure compliance, then the Division may reevaluate and modify this General Water Quality Certification. 16. Certificate of Completion When written authorization is required for use of this certification, upon completion of all permitted impacts included within the approval and any subsequent modifications, the applicant shall be required to return the certificate of completion attached to the approval. One copy of the certificate shall be sent to the DWQ Central Office in Raleigh at 1650 Mail Service Center, Raleigh, NC, 27699-1650. Non-compliance with or violation of the conditions herein set forth by a specific project shall result in revocation of this Certification for the project and may also result in criminal and/or civil penalties. Water Quality Certification No. 3689 Water Quality Certification No. 3689 The Director of the North Carolina Division of Water Quality may require submission of a formal application for Individual Certification for any project in this category of activity if it is determined that the project Is likely to have a significant adverse effect upon water quality including state or federally listed endangered or threatened aquatic species or degrade the waters so that existing uses of the wetland or downstream waters are precluded.
