We offer the following comments/questions/request for additional information for your review and response. Please provide your responses no later than close of business on April 13, 2024. General Topics The submittal states you are requesting a reissuance of the permit issued in 2011. This permit expired nearly 8 years ago, and site conditions have changed (including ownership and environmental resources). Therefore, this permit request is a new permit and will be evaluated as such. 2. Please provide the updated delineation of the ponds, proposed access road locations, and the areas where the fill will be obtained from and/or stockpiled. 3. It would be helpful for the agency review to have all the specifics with regard to mitigation that was purchased for each location, the as-builts, and any other pertinent historical documentation of this project area in this submittal. 4. Please provide any information regarding surveys and/or recommendations under the Endangered Species Act. 5. Please provide any information regarding surveys and/or recommendations with regard to historic and/or cultural resources that may be protected under the National Historic Preservation Act. -2- Hole #13 Pond 6. What was the original capacity design for the Hole #13 Pond? It appears that the capacity would increase by approximately two times the original design? This increase in capacity does not include the pond proposed for decommissioning for the pickleball courts, does it? Also, since the capacity has been increased, would that reduce the flow from the outfall? 7. If the diversion drainage feature for the Hole #13 Pond is slated for impact, please provide the delineation of this feature, impact amount, and why no proposed compensatory mitigation was proposed. Pickleball Pond 8. If the pond proposed for decommissioning for the pickleball courts was no longer needed for fire suppression, why did Balsam Mountain Preserve continue diverting flow to this feature? 9. How will the new concrete cistern/settlement box discharge into the stream? Will there be impacts to the stream below the ordinary high water mark? If so, please provide the plan and documentation regarding impacts. 10. Please provide a formal planset for the installation of the pickleball court including grading, pond decommissioning, etc. In addition to our comments above, we received the attached comments that also need to be addressed in your response. If you have any questions regarding this correspondence, please do not hesitate to contact me by phone at: 828-271-7980, ext. 4232, or by email at: brooke.a.davis(a)-usace.army.mil. Sincerely, Brooke Davis Regulatory Project Manager Asheville Regulatory Field Office Wilmington District ® North Carolina Wildlife Resources Commission Cameron Ingram, Executive Director March 12, 2024 Ms. Brooke Davis U.S. Army Corps of Engineers, Regulatory Branch 151 Patton Avenue, Room 208 Asheville, North Carolina 28801-5006 SUBJECT: Balsam Mountain Preserve Irrigation Pond and Pickleball Courts Project SAW-2007-02076 UT South Fork Sugarloaf Creek, Jackson County Dear Ms. Davis: Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an application to fill 0.12 acre of open water off Sugarloaf Creek and to redesign an existing in -line pond on an unnamed tributary (UT) to South Fork Sugarloaf Creek in Jackson County. NCWRC staff last visited the site on March 8, 2024. Our comments on this application are offered for your consideration under provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). There are Brook Trout in South Fork Sugarloaf Creek. We are concerned about the maintenance of this population of sensitive species. In order to protect this sensitive species, a trout moratorium from October 15 to April 15 is typically required for in -stream activities or activities that are adjacent to streams that have a substantial risk of sediment loss to those streams. The applicant has requested a waiver of the trout moratorium. Given the amount of earthwork involved in rebuilding the pond and dam and their proximity to the stream, we are reluctant to grant a waiver for this proj ect. The applicant proposes to fill an existing off-line pond near Sugarloaf Creek to build pickleball courts and to enlarge an existing irrigation pond at Hole 913. The irrigation pond at Hole 913 is fed by two sources - an UT to South Fork Sugarloaf Creek and South Fork Sugarloaf Creek itself. This pond was unpermitted when initially built and failed soon after construction. The UT South Fork Creek is diverted into the pond but portions of the flow are sometimes allowed to bypass the pond through a bypass channel. An intake pipe is set up across the golf course on South Fork Sugarloaf Creek; this pipe pulls water from the stream and diverts it to the pond. The pond would be enlarged to 1 acre at normal pool elevation and deepened to 7 ft. The bottom would be dug down 2 ft, and the dam would be rebuilt accommodate a normal pool elevation of 3,680 ft above sea level. The pond would be outfitted with a riser pipe with coolwater release in the Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 Balsam Mtn Preserve Pond & Pickleball Page 2 March 12, 2024 UT S Fork Sugarloaf Cr, Jackson Co form of a small (7/8-inch) hole in the elbow to pull a constant flow of 80% of the estimated 7Q10 (calculated as 0.04 cfs) of the UT. The dam would be reconstructed, an emergency spillway constructed, and unstable slopes of the pond addressed. We offer the following recommendations to minimize impacts to fish and wildlife resources: • We appreciate the efforts to incorporate a coldwater release and minimum flows from the irrigation pond. However, the proposed minimum flows of 80% of 7Q10 is inadequate. To protect sensitive aquatic species such as Brook Trout, NCWRC typically recommends a minimum flow of 70% of incoming flows. • The diversion channel is currently vegetated, although there are eroding rills in the channel, especially near the downstream end. We are concerned about continued erosion and downcutting of the channel if the entire stream flow is diverted into this channel. We recommend evaluating the stability of the channel and ensuring that stream flow diversion does not result in channel additional instability and erosion. Additional riprap or piping of the flow could prevent this. • The pond construction sequence includes diverting stream flows through the pond riser (Step 97). How will this be accomplished? • Will the amount of water pulled from the irrigation pond change with the increase in volume? If so, how will the withdrawals from both the UT and the mainstem South Fork Sugarloaf Creek change? • The current withdrawals from South Fork Sugarloaf Creek should be characterized. How much flow is withdrawn? What proportion of the stream is withdrawn? • Any erosion control matting used should be free of plastic or nylon mesh, as this type of mesh netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last for years. • Work involved in rehabilitating the irrigation pond should be performed outside of the moratorium of October 15 to April 15 to minimize impacts to wild Brook Trout reproduction. • We recommend that the applicant build the pickleball courts in a way that allows at least 30 ft of buffer between them and the stream. We recommend widening the existing thin buffer to 30 ft in width with native shrubs and trees. Thank you for the opportunity to review and comment on this project.

As I wasn't at the meeting in 2023, it would be very useful to see the site this week if at all possible. Please let me know if you could swing that. 2. Irrigation pond a. This pond is to be expanded from its current dimensions. Please describe how/if the pond dimensions (area, depth) differ from the originally permitted pond. b. How will flows from the southern tributary be diverted during construction? c. Minimum flows. i. We appreciate that minimum flows are taken into consideration. However, 80% of 7Q 10 flows is very small. South Fork Sugarloaf Creek does support Brook Trout. Our starting place for a Brook Trout stream is 70-80% of incoming flows. We understand that this stream is a very small headwater stream, ii. Did the engineer request flow information from USGS? Typically, USGS can provide information that is better fitted to the geographic location than the generalized regression equations used. Please provide the USGS-generated numbers for flow statistics. iii. Please note that minimum flows will need to be maintained during pond fill. 3. Pickleball pond - please provide details on how the pond will be drained.

Davis, Brooke A CIV USARMY CESAW (USA) From: Bowers, Todd <bowers.todd@epa.gov> Sent: Tuesday, February 27, 2024 2:40 PM To: Davis, Brooke A CIV USARMY CESAW (USA) Subject: [Non-DoD Source] U.S. Army Corps of Engineers Public Notice for SAW-2007-02076 Brooke, The EPA Region 4 Ocean, Wetlands and Streams Protection Branch has reviewed the subject USACE Individual Public Notice under DA Action ID SAW-2007-02076 dated February 12, 2024. It is our understanding that the applicant, Balsam Mountain Preserve. is seeking Department of the Army authorization to discharge fill material into open waters and an unnamed tributary to the South Fork of Sugarloaf Creek associated with the installation of pickleball courts and dam rehabilitation/repair, respectively. The proposed project is located within the Balsam Mountain Preserve near the Town of Sylva in Jackson County, North Carolina. Specifically per the project narrative, purpose and description, the Applicant's preferred alternative consists of a location currently occupied with apreviously authorizedpond. The 0.12-acre pond, originally constructed in 2007 for use for fire suppression. The limits of disturbance (LOD) for the pickleball courts would be approximately 0.3 acres and include three pickleball courts, retaining walls, and infrastructure for a pedestrian pathway. Therefore, the Applicant is proposing to fill the entire 0.12-acre open water feature. Fill for the pond would come from home construction sites on the Preserve property. The secondproposed activity consists of dam structural repair associated with apreviously authorized irrigation pond, adjacent to the Hole #13, within the golf course. The installation of the online pond and associated dam within the unnamed tributary to the South Fork of Sugarloaf Creek was previously authorized in 2003. The original footprint impacted approximately 153 linear feet of stream. It was used for irrigation for approximately one year before June 7, 2007, when the pond's dam failed and caused degradation to downstream areas. The Corps issued apermit, including compensatory mitigation for the stream loss, for the rehabilitation of this dam in 2009, which was renewed in 2011, but has since expired. The rehabilitation of the dam was never completed after the 2009 and 2011 permits due to funding constraints. Compensatory mitigation is not proposed for this project since both activities would occur within previously authorized areas for which the impacts already been mitigated. At this time, the EPA has no comments or concerns with the project as presented. Thank you for the opportunity to provide oversight and review on DA Action ID SAW-2007-02076 to discharge fill material into open waters and an unnamed tributary within the Balsam Mountain Preserve near the Town of Sylva in Jackson County, North Carolina.
