Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The Project is located in the Town of Waynesville Haywood County NC The project site consists of the existing Maunev Cove Road Convenience Center, adjoining vacant area to the west, and two drainage easement areas to the south of Maunev Cove Road. The project site is located near the intersection of Maunev Cove Road and Highway 276 (Russ Avenue). See Location Map. The Project site is an active, county run, solid waste transfer station that consists of a 1/3 -acre fenced -in concrete pad and gravel lot with recycling and solid waste collection containers and a solid waste compactor unit. The remaining portion of the Project parcel to the west is sparsely wooded. Two small wetland areas were found on the Proiect site: 1). Wetland Unit 'WA' is an herbaceous dominated seep located southwest of the transfer station near the ditchline along Maunev Cove Road. Wetland Unit 'WA' drains to the northeast through a 12" CMP under the convenience center's southern access road and continues within the ditchline as a linear feature before ending at the northern access road. 2). Wetland Unit 'WB' is a riparian wetland along Maunev Cove Branch located at the outlet end of an existing stormwater 18"RCP which drains the ditchline between the transfer station facility and Maunev Cove Road Maunev Cove Branch. a Derennial stream system that drains northeast into Lake Junaluska is located on the southeastern side of Maunev Cove Road opposite of the convenience center (see Delineation and Impacts Map) Surrounding areas to the project site include agricultural, residential, commercial and recreational land -uses 3b. List the total estimated acreage of all existing wetlands on the property: WL -A: 0.019 -acres (833 M. WL -B: 0.003 -acres (133 M. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: Maunev Cove Branch runs Darallel and to the south of Maunev Cove Road within the Maunev Cove Road Baht -of -way for approximately 400 If. 3d. Explain the purpose of the proposed project: The purpose of the Droiect is to expand and upgrade the Maunev Cove Convenience Center. ExDansion will allow for the center to collect and process more waste benefiting the local community. Upgrades to the on-site drainage system will improve stormwater management, treatment and detention reducing the amount of sediment currently leaving the site and entering Maunev Cove Branch. Page 4 of 15 3e. Describe the overall project in detail, including the type of equipment to be used: The Maunev Cove Convenience Center project includes clearina and re-aradina approximately 1.29 -acres on the Project parcel for expansion of the facility's paved operations area, installation of concrete curb and gutter, two access roads, and new permanent stormwater BMPs. The two existing 18" CMPs under the access roads, existing fencing, existina solid waste containers, and existina asphalt and concrete pads will be removed (see Sheet C-101 Existing Conditions and Demolition Plan). Proposed project actions would add approximately 0.3 -acres of new paved operations area to the western portion of the facility and would also include widening and improving the tum radius of the two existing facility access roads. Proposed new on-site stormwater BMPs would include installation of an 85' x 30' sediment basin in the southwest comer of the proiect area which would transition into a permanent 70' x 20' bioretention cell. A yard inlet in the eastern end of the basin/cell will outfall into a proposed approx. 61 If 18" HDPE under the western entrance drive. Stormwater would then outfall to Maunev Cove Branch via a proposed approx. 37 If 18" HDPE crossing under Maunev Cove Road. An approx. 140 If vegetated ditch line between the facility and Maunev Cove Road will outfall via an awrox. 53 If 18" HDPE under the eastern access road. Stormwater will then enter an existing 18" RCP storm drain running under Maunev Cove Road and discharain-g into a rip -rap pad and eventually into Maunev Cove Branch. Concrete headwalls will be constructed at all proposed pipe inlets and outlets for protection. A concrete headwall is proposed for the inlet of the existing 18" RCP crossing under Maunev Cove Road. The existing sediment at the outlet end of this Dim will be removed and restored with rip -rap Dad (see Sheets C-103 Grading and Erosion Control Plan, C-104 Stormwater Plan, C-502, C-504 Miscellaneous Details). The rip -rap pad will be embedded and underlain with filter cloth to avoid erosion and to maintain outlet stability. Once final grading is complete, a veaetative buffer will be established to the north and west of the project area, and landscaped areas installed between the convenience center property and Maunev Cove Road (see Sheet C-102 Site Plan . Proposed project actions would permanently impact Wetland Unit 'WA'. Wetland impact W-1 (see Delineation & Impact Map) would result from excavation and filling 0.019 -acres of Wetland Unit 'WA' to accommodate the widening of the facility access roads and installation of the bioretention cell BMP and ditch D2 (see Sheet C-104. Detail C-502). The construction of the bioretention cell will allow for stormwater to be detained and treated before being discharged off-site. The project site has a high water table and must be filled to achieve elevations necessary for proper stormwater BMP function. Final -grade was designed to ensure that the proposed bioretention cell and ditch D2 could efficiently drain stormwater off-site without bonding and saturation which could dearade proposed infrastructure. Proposed actions will also permanently impact Wetland Unit 'WB'. Wetland impact W-2 (see Delineation & Impact Map) would result from removina the sediment from the outlet area of the existing 18" RCP along Maunev Cove Branch and installing permanent rip -rap protection. The existing 18" RCP is completely blocked at the outlet end with the accumulated sediment and does not function properly during storm events. The proposed work - and Impact W-2 - will restore proper function. Access road widenina and construction of the BMPs would be completed by excavator, bull dozer and dump truck. Proposed Project actions would permanently impact Maunev Cove Branch. Stream impact S-1 would result from filling 6 linear feet along the left bank of Maunev Cove Branch with the installation of a concrete headwall (see Sheets C - C104 Stormwater Plan and C-504 Miscellaneous Details). Temporary stream impacts S-2 and S-3 would result from using approx. 2 -foot high sandbag coffer dams to isolate the areas of stream bank work durina installation of new headwall and rib -rap pad, and will allow work to be performed in the dry. Disturbed areas of the stream bank will be stabilized following proposed work with coir mattin-g, and temporary erosion control and native seed mix. Outfall protection work will be completed by trackhoe and dump truck. Page 5 of 15 4. Jurisdictional Determinations 4a.

Explain: 1 Boxes checked below shall be supported by completing the appropriate sections in Section Ill below. ' For purposes of this form, an RP W is defined as a tributary that is not a TN W and that typically flows year-round or has continuous clow at least "seasonally" (e.g., typically 3 months). 'Supporting documentation is presented in Section III. F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section HI.A.1 and Section III.D.I. only; If the aquatic resource is a wetiand adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.I.; otherwise, see Section I11.8 below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjaoent": B. CHARACTERISTICS OF TRIBUTARY ("THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rnponos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), I.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW Is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that Is not perennial (and Its adjacent wetlands If any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine If the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and aft of its adjacent wetlands Is used whether the review area identified In the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section 13I11.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section HI.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined In Section III.0 below.

(YIN) Size lin acres) 'AW' N 0.02 Summarize overall biological, chemical and physical functions being performed: Wetland Unit 'AW'provides herbaceous plant material foodsource for wildlife, groundwater recharge, nutrient and organic carbon for downstream foodwebs, and pollutant trapping mechanism. C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, In combination with all of Its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the Flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It Is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified In the Rgpanos Guidance and discussed In the Instructional Guidebook, Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or food waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other,relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not Inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWL Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section fil.D: . 2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section IIi.D: 3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: Wetland Unit 'AW' is located adjacent to Mauney Cove Branch (RPW), but this wetland provides a hydrological and chemical connective nexus with the RPW. Wetland'AW is connected by drainage pipes to Mauney Cove Branch. Wedand'AW' provides baseflow to Mauncy Cove Branch and nutrient and organic carbon for in -stream foodwcbs. D.
