Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:* Mirror Lake has two primary tributaries, the Cullasaja River and Mill Creek. Previous watershed studies have noted "extremely high sediment accumulation" within the lake from decades past in addition to recent development (Upper Cullasaja Watershed Strategy and Action Plan, 2004). The sediment has reduced aquatic habitat necessary trout and other fish and benthic organisms. Both tributaries are listed on the 2022 303(d) list as impaired for Benthos. The increase in nutrients released from the sediment has contributed to excessive algae and eutrophication. The shallower depths have increased water temperatures, and impaired recreational uses. The area to be utilized for access has been maintained with gravel adjacent to the asphalt road. The area to be used for dewatering has been a grassed/mowed area for the community to access the lake over the years. According to the same study, the watershed is approximately 50 % forested or undeveloped and 50 % residential, commercial or industrial. Much of the land adjacent to the Cullasaja River and it tributaries has been cleared of riparian vegetation by development in the watershed. The watershed continues to experience rapid growth and development due to increasing popularity as a retirement and vacation community. Only 13 % of the watershed is in the National Forest. The majority of the acreage in the watershed is privately owned, and 40 % of the watershed is located within the town limits of Highlands, NC. Point and non -point sources of wastewater are existing in the watershed with the urban area directly upstream and residential housing throughout the watershed (many with aging septic systems). No previous dredging or sediment removal has taken place within the lake, and sediment survey data suggests more than 100,000 cubic yards of sediment are within the lake at this time. 4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past? * Yes No Unknown 4f. List the total estimated acreage of all existing wetlands on the property: 5.43 4g. List the total estimated linear feet of all existing streams on the property: 0 (property is composed of the lake itself) 4h. Explain the purpose of the proposed project: The purpose of the project is to remove the accumulated sediment from the lake. Removing sediment will restore impaired aquatic habitat, reduce water temperatures, increase dissolved oxygen, increase storage capacity (reduce flooding), improve recreational activities, improve aesthetics, and increase the value of a community asset. Sediment will be removed from the lake and disposed of in an off -site, upland location. 4L Describe the overall project in detail, including indirect impacts and the type of equipment to be used: * The project will involve dredging the sediment from the lake. The primary method will utilize a hydraulic cutterhead dredge. The dredge will access the lake via an existing boat ramp. It floats on the water and "vacuums" the silt from the lake using a cutterhead that gathers the silt into the pipe connected to a pump. The pump then transports the silt in a sealed (HDPE, plastic, 6 inch diameter) pipeline to a dewatering location. The dewatering location will contain a dewatering system. The dewatering system will be a geosynthetic tube that collects the slurry. The silt is separated from the water before the clean water is returned to the lake. The clean water is collected on a plastic sheet to prevent any erosion at the site. A mechanical dewatering device may also be in place to aid in separation of coarse sediment particles. A polymer injection system (using NSF approved materials) may also be used to aid in the separation of silt and clay particles from the slurry within the tube. Turbidity curtains within the lake may also be deployed if necessary to improve water clarity within the limited work/discharge zone. Once the dewatering system is at capacity (full), a drying time will allow the excess water to drain from the silt. The tube will be cut open so that the dried silt can be removed with an excavator and loaded in sealed dump trucks for transport off -site. Another cycle will be completed with a new tube at this time. These cycles will continue until the target volume of sediment is removed from the lake. The impacts from the access are very minimal because of the existing access being present. The impact from the dewatering area is minimized because of the small footprint (100'x30' area for the tube plus the edges), and the area is already cleared (no trees, only grass). The dewatering area will be restored to its current condition once the project is complete. The dredge is very limited because the sediment that is touches is the sediment that it removes. It is a precise technique that impacts only the area targeted in a surgical manner. This method has been proven in many similar situations and is a very effective, low impact method. 5. Jurisdictional Determinations 5a. Have the wetlands or streams been delineated on the property or proposed impact areas?* Yes Comments: No 5b. If the Corps made a jurisdictional determination, what type of determination was made? * Preliminary Approved Not Verified Unknown N/A Corps AID Number: 5c. If 5a is yes, who delineated the jurisdictional areas? Name (if known): Agency/Consultant Company: Other: 6. Future Project Plans 6a. Is this a phased project?* Yes No O Unknown Are any other NWP(s), regional general permit(s), or individual permits(s) used, or intended to be used, to authorize any part of the proposed project or related activity? D. Proposed Impacts Inventory 1. Impacts Summary 1a. Where are the impacts associated with your project? (check all that apply): Wetlands Streams -tributaries Buffers Open Waters Pond Construction 4. Open Water Impacts 4a. Site # 4a1. Impact Reason 4b. Impact type 4c. Name of waterbody 4d. Activity type :114e. Waterbody type 4f.

Comments: Dredging of the lake and discharge of the water back into the same lake once the sediment is removed; Dewatering will utilize the temporary use of less than 1 acre adjacent to the lake E. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project: Not draining the lake completely which would increase the impact on aquatic life. Not dredging or siphoning sediment as a "pass-thru" technique that discharges sediment past the dam to downstream waters Not clearing highly erodible/steep land for dewatering purposes No buffer clearing for access along the edge of the lake around the whole boundary No permanent disturbances and very little temporary disturbance 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques: Selecting the proper dredge size to reduce impact at the expense of production Proper dewatering techniques and technology Surgical approach to dredging 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State? Yes No 2b. If this project DOES NOT require Compensatory Mitigation, explain why: This project restores and rehabilitates the impacts that are impairing the waters by excessive sedimentation. The project avoids and minimizes any other effects in the process. F. Stormwater Management and Diffuse Flow Plan (required by DWR) 1. Diffuse Flow Plan 1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules? Yes No If no, explain why: The only flow created is the return water from the dredging process back into the lake. This water is collected on a plastic sheet to prevent any erosion from the dewatering area and returned tot he lake without flowing/eroding the soil beneath the plastic. 2. Stormwater Management Plan 2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250? Yes No 2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)? Yes No Comments: G. Supplementary Information 1. Environmental Documentation 1a. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? * Yes No 2. Violations (DWR Requirement) 2a. Is the site in violation of DWR Water Quality Certification Rules (15A NCAC 2H .0500), Isolated Wetland Rules (15A NCAC 2H .1300), or DWR Surface Water or Wetland Standards or Riparian Buffer Rules (15A NCAC 2B .0200)? * Yes No Q L 3. Cumulative Impacts (DWR Requirement) 3a. Will this project result in additional development, which could impact nearby downstream water quality?'� Yes No 3b. If you answered "no," provide a short narrative description. This is not a project related to development but instead is restoring water quality. 4. Sewage Disposal (DWR Requirement) 4a. Is sewage disposal required by DWR for this project?" Yes No N/A 5. Endangered Species and Designated Critical Habitat (Corps Requirement) 5a. Will this project occur in or near an area with federally protected species or habitat?* Yes No 5b. Have you checked with the USFWS concerning Endangered Species Act impacts? Yes No 5d. Is another Federal agency involved?* Yes No 5e. Is this a DOT project located within Division's 1-8? Yes No 5f. Will you cut any trees in order to conduct the work in waters of the U.S.? Yes No 5g. Does this project involve bridge maintenance or removal? Yes No 5h. Does this project involve the construction/installation of a wind turbine(s)?* Yes No Unknown 5i. Does this project involve (1) blasting, and/or (2) other percussive activities that will be conducted by machines, such as jackhammers, mechanized pile drivers, etc.? Yes No 5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? IPaC 6. Essential Fish Habitat (Corps Requirement) 6a. Will this project occur in or near an area designated as an Essential Fish Habitat?* Yes No 6b. What data sources did you use to determine whether your site would impact an Essential Fish Habitat? NOAA EFH Mapper 7. Historic or Prehistoric Cultural Resources (Corps Requirement) 7a. Will this project occur in or near an area that the state, federal or tribal governments have designated as having historic or cultural preservation status? Yes No 7b. What data sources did you use to determine whether your site would impact historic or archeological resources?" HPO Mapping suggests that the project is within the "Mirror Lake Historic District"; However, the restoration of the lake will not negatively impact the district but is instead an attempt to help preserve the community and it's resource. We are only removing recent sediment/silt and no historical/cultural materials. 8. Flood Zone Designation (Corps Requirement) 8a. Will this project occur in a FEMA-designated 100-year floodplain?" Yes No 8b. If yes, explain how project meets FEMA requirements: The project does not involve and permanent structures. The project is designed to be done within the water and floodplain. 8c. What source(s) did you use to make the floodplain determination?" FEMA Map - The project is within the lake which is within the boundary. However, the project will increase the water storage capacity and therefore may decrease flooding.
