The work will take place on parcels 1639433 and 1639438 owned by Larry C Hill Trustee of Delray Beach Florida and John R Jennings of Vero Beach Florida, members of the POA. B. Project Information and Prior Project History 3e. Describe the overall project in detail, including the type of equipment to be used: The project will implement the Corrective Action Plan approved by the Division of Water Resources on April 29, 2020 as a response to a Notice of Violation issued August 22, 2019. (Attachment A). The Corrective Action Plan includes implementation of attached repair plans at the location of the upland slope failure, as well as removal of sediment in the unnamed tributary to Lake Lure. The corrective action plan approval, and repair plans produced by Odom Engineering PLLC are in Attachment B. Impacts to Waters of the US associated with the repairs are included in Figure 5. An existing 40' culvert was bypassed and removed as a result of this project. Stream Impact S1 is the placement of the stream off line into 151 LF of 18" HDPE and 36" x 36" catch basin before rerouting into the stream bed, resulting in the loss of 47 LF of original stream length, and S2 is the construction of a series of stepped plunge pools (35 LF) to stabilize the stream bed and banks and dissipate energy. F. Supplementary Information 5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? CEC Consulted the US Fish and Wildlife Service (USFWS) list of federally protected species for Rutherford County, the USFWS Northern Long -Eared Bat Consultation areas Map for Rutherford County, and the NC Natural Heritage Program (NCNHP) Database for federally listed species within a one mile radius of the site. USFWS indicates that the project area is in a HUC known to contain Maternity Trees or Hibernacula. The NCNHP database indicates that there are two known element occurrences of white irisette (Sisyrinchium dichotomum) , a federally endangered plant, within a one mile radius of the site. (Attachment C) It is the opinion of CEC that there is no suitable habitat for white irisette within the proposed project area.

Temporary ground stabilization shall be maintained in a manner to render the surface stable against accelerated erosion until permanent ground stabilization is achieved. GROUND STABILIZATION SPECIFICATION Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the techniques in the table below: Temporary Stabilization Permanent Stabilization • Temporary grass seed covered with straw or •Permanent grass seed covered with straw or other mulches and tackifiers other mulches and tackifiers • HY droseeding •Geotextile fabrics such as permanent sail • Rolled erosion control products with or reinforcement matting without temporary grass seed • Hyd roseeding - traw or other mulch •Shrubs or other permanent plantings covered .-w.-_-_",-_..-�___ � with mulch •Uniform and evenly distributed ground cover sufficient to restrain erosion • Structural methods such as concrete asphalt or retaining walls • Rolled erasion control products with grass seed POLYACRYLAMIDES (PAMS) AND FLOCCULANTS 1. Select flocculants that are appropriate for the soils being exposed during construction selecting from the NC DWR List of APP roved PAMS/ flocculants. 2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures. 3. Apply flocculants at the concentrations specified in the NC DWR List of Approved PAMS/flocculants and in accordance with the manufacturer's instructions. 4. Provide ponding area for containment of treated Stormwater before discharging offsite. 5. Store flocculants in leak -proof containers that are kept under storm -resistant cover or surrounded by secondary containment structures. EQUIPMENT AND VEHICLE MAINTENANCE 1. Maintain vehicles and equipment to prevent discharge of fluids. 2. Provide drip pans under any stored equipment. 3. Identify leaks and repair as soon as feasible, or remove leaking equipment from the project. 4. Collect all spent fluids, store in separate containers and properly dispose as hazardous waste (recycle when possible). 5. Remove leakingvehicles and construction equipment from service until the problem has been corrected. 6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products to a recycling or disposal center that handles these materials. LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE 1. Never bury or burn waste. Place litter and debris in approved waste containers. 2.

Ensure that the subgrade for the filter and riprap follows the required lines and grades shown in the plan. Compact any fill required in the subgrade to the density of the surrounding undisturbed material. Low areas in the subgrade on undisturbed soil may also be filled by increasing the riprap thickness. 2. The riprap and gravel filter must conform to the specified grading limits shown on the plans. 3. Filter cloth, when used, must meet design requirements and be properly protected from punching or tearing during installation. Repair any damage by removing the riprap and placing another piece of filter cloth over the damaged area. All connecting joints should overlap so the to P layer is above the downstream layer a minimum of 1 foot. If the damage is extensive, replace the entire filter cloth. 4. Riprap may be placed by equipment, but take care to avoid damaging the filter. 5. The minimum thickness of the riprap should be 1.5 times the maximum stone diameter. 6. Riprap may be field stone or rough quarry stone. It should be hard, angular, highly weather -resistant and well graded. 7. Construct the apron on zero grade with no overfill at the end. Make the top of the riprap at the downstream end level with the receiving area or slightly below it. 8. Ensure that the apron is properly aligned with the receiving stream and preferably straight throughout its length. If a curve is needed to fit site conditions, place it in the upper section of the apron. 9. Immediately after construction, stabilize all disturbed areas with vegetation (Practices 6.10, Temporary Seeding, and 6.11, Permanent Seeding). 1. All erosion and sediment control practices will be checked for stability and operation following every runoff -producing rainfall but in no case less than once every week. Any needed repairs will be made immediately to maintain all practices as designed. 2. Sediment will be removed behind the sediment fence when it becomes about 0.5' deep at the fence. The sediment fence will be repaired as necessary to maintain a barrier. 3. All seeded areas will be fertilized, reseed as necessary according to specifications in the vegetative plan to maintain a vigorous, dense, vegetative cover. aBBNNIEeNArttrr" .

A taxon "in danger of extinction throughout all or a significant portion of its range." T = threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a significant portion of its range." C = candidate. A taxon under consideration for official listing for which there is sufficient information to support listing. (Formerly "Cl" candidate species.) BGPA =Bald and Golden Eagle Protection Act. See below. ARS = At Risk Species. Species that are Petitioned, Candidates or Proposed for Listing under the Endangered Species Act.

T(S/A) = threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with another listed species and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered or threatened and are not subject to Section 7 consultation. See below. EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental, nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land, for consultation purposes, and as species proposed for listing on private land. P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT", respectively. Bald and Golden Eagle Protection Act (BGPA)_ In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de -listed) from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After delisting, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) becomes the primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a statutory definition of "take" that includes "disturb". The USFWS has developed National Bald Eagle Management Guidelines to provide guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information, visit http://www.fws.gov/migratorybir ds/baldeagle.htm Threatened due to similarity of appearance(T(S/A))_ In the November 4, 1997 Federal Register (55822-55825), the northern population of the bog turtle (from New York south to Maryland) was listed as T (threatened), and the southern population (from Virginia south to Georgia) was listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the collection and interstate and international commercial trade of bog turtles from the southern population. The T(S/A) designation has no effect on land management activities by private landowners in North Carolina, part of the southern population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern population of the bog turtle as a Federal species of concern due to habitat loss. Definitions of Record Status: Current - the species has been observed in the county within the last 50 years. Historic - the species was last observed in the county more than 50 years ago. Obscure - the date and/or location of observation is uncertain. Incidental/migrant - the species was observed outside of its normal range or habitat. Probable/potential - the species is considered likely to occur in this county based on the proximity of known records (in adjacent counties), the presence of potentially suitable habitat, or both. 2 of 2 6/8/2020, 5:58 PM a ■■N Roy Cooper.

ClearWater Environmental Consultants, Inc. 32 Clayton Street Asheville, NC 28801 RE. Highlands at Lake Lure, 592 Dear ClearWater Environmental Consultants, Inc.: The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence, the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also included in this report. If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or Federally -listed species are documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rodnev.butlerWncdcr.aov or 919-707-8603.
