X[ igation D WQ - In accordance with 15A NCAC 2H .0500, mitigation may * be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation'plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant,may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at httl3://h?-o.enr.state.ne.us/ncwetlands/stn-ngide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin,. type and amount (acreageAinear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, . preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP) with the NCWRP's -written agreement. Check the box indicating that you would like to pay into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by the 401/Wedands Unit if payment into the NCWRP is available as an option.

CESAW Form 591 RWaed JWy 1996 -r 01 North Carolina Wildlife Resources Commission 9 Charles R. Fullwood, Executive Director March 29, 2004 Mr. David Baker U. S. Army Corps of Engineers Regulatory Branch 151 Patton Avenue, Room 208 Asheville, North Carolina 28801-5006 SUBJECT: Mr. Edward Snowden 404 permit Application Pond Construction- UT Cold Branch Clay County, North Carolina. Dear Mr. Baker: Mr. Edward Snowden is requesting a letter of concurrence from the North Carolina Wildlife Resources Commission (Commission) for a 404 permit from the U. S. Army Corps of Engineers. We reviewed the information provided by the applicant and spoke with Mr. Snowden most recently on March 29, 2004 regarding the project. Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). The applicant proposes to construct a pond and two sediment traps on an unnamed tributary (UT) to Cold Branch near Hayesville. The pond is needed to water horses. Total reported impact of the construction is 200 linear feet in what appears to be an intermittent stream or spring seep. Cold Branch is classified as C by the Division of Water Quality and not designated as trout waters by the Commission. Tusquitee Creek downstream of Cold Branch is classified as C trout HQW and designated hatchery supported water. The UT to be impacted by the pond is not depicted as a stream on the U.S. Geological Survey map, and according to Mr. Snowden, it is very small and periodically goes dry. Based on this information, it is our opinion that the stream is not sufficient in size to support trout and that the project will not directly affect trout. Our primary concerns with the project are potential adverse effects on aquatic habitats in downstream areas of Cold Branch where trout may occur. Dam construction and impounding of stream flow by the pond could degrade habitat by contributing to sedimentation and elevated water temperatures in the watershed. Therefore, the Commission will concur with issuance of a 404 Permit for the project provided the following conditions, which we feel would minimize effects of the project on aquatic resources, are attached to the permit and adhered to: 1. Adequate sedimentation and erosion control measures must be implemented prior to any ground-disturbing activities to minimize impacts to downstream aquatic resources. Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15 Mailing Address: Division of Inland Fisheries • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 733-3633 ext. 291 • Fax: (919) 715-7643 r_ __' Page 2 29 March 2004 Snowden Pond, UT Cold Branch Clay County days of ground disturbing activities to provide long-term erosion control. Erosion control matting in conjunction with appropriate seeding should be used on disturbed soils adjacent to streams, slopes of the dam, and other disturbed areas instead of straw mulch. 2. To minimize temperature impacts on downstream waters, native woody vegetation (e.g., rhododendron, dog hobble, red maple) should be reestablished along the pond and stream channel to provide canopy cover. Also, the pond outflow pipe must be designed to draw water from near the bottom of the pond. Cold water intakes should be within 1-2 feet of the bottom, but not on the bottom. This design will also prevent buildup of poorly oxygenated water and improve water quality in the pond. The easiest way to accomplish a near-bottom outflow is to place a larger pipe over the standpipe so that water flows into the bottom of the larger pipe, as shown below. pond surface water flow pond bottom 3. If concrete is used during dam construction, adequate precautions must be taken to prevent direct contact between uncured concrete and stream water. Water that has come in contact with uncured concrete should not be discharged to surface waters because of the potential for elevated pH. 4. For pond construction, excavation of the stream and the disturbance within the pool area should be conducted in the dry. Sandbags, cofferdams, flexible pipe, or other diversion structures should be used to bypass stream water around the excavation and construction areas. 5. When filling the pond, residual flow in the stream below the dam must be sufficient to prevent adverse effects on downstream aquatic resources. This can be accomplished by partially opening the gate valve during the filling process. However, turbid water should not be discharged to downstream reaches. Until the water in the pond is clear, flexible pipe should be used to maintain a bypass stream flow. b. Excavation of the area downstream of the pond outlet should be avoided to the greatest extend practicable. The discharge point should be stabilized with rock to prevent scouring and adjacent areas allowed to revegetate with rhododendron and other native vegetation. 7_ Under no circumstances should rock, sand, or other materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate vicinity . of the ponds. In stream dredging has catastrophic effects on aquatic life, and disturbance of the natural form of the stream channel will likely cause downstream erosion problems, possibly affecting adjacent landowners. 8. Ripmp placed for bank stabilization should be limited to the streambank below the high-water marls, and vegetation should be used for stabilization above the high water elevation. Page 3 29 March 2004 Snowden Pond. UT Cold Branch Clay County 9. All mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids or other toxic materials. 10. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. Thank you for the opportunity to review and comment on this project. Pending availability of field staff, the Commission may inspect the work site during or after construction.
