The project involves construction of an irrigation intake in the Tuckaseegee River that would provide water to a new golf course near Whittier in Jackson County. Comments from the Commission are provided under 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). A few trout may be found in the river near the site, but spawning is not expected. However, the river is designated an Aquatic Significant Natural Heritage Area of national significance because of numerous rare aquatic species. It also is designated critical habitat for the federally endangered Appalachian elktoe (Alasmidonta raveneliana) under the Endangered Species Act. These mussels are found near and possibly within the site. Other rare aquatic species in the project vicinity include hellbender (Cryptobranchus alleganiensis, FSC, NC-SC), wounded darter (Etheostoma vulneratum, FSC, NC-SC), olive darter (Percina squamata, FSC, NC-SC), and wavy-rayed lampmussel (Lampsdis fasciola, NC-SC). The intake could harm mussels during its construction. During intake operation, early life stages of sicklefin redhorse and other fish that serve as hosts for mussels may be entrained or impinged, though the degree of this would depend on the intake withdrawal rate, duration, timing, and other factors not Mailing Address: Division of Inland Fisheries - 1721 Mail Service Center - Raleigh, NC 27699-1721 Telephone: (919) 707-0220 - Fax: (919) 707-0028 EBCI Page 2 March 10, 2008 Jackson County specified in the application. Sicklefin redhorse have recently been reintroduced into the river in an effort to restore a population. Their eggs seem to be cohesive, but larval stages would likely be vulnerable to a withdrawal. If they become established in the river, then losses of larvae may occur if the intake is operated during the spring spawning season and early summer. Although the project meets the limits of a Nationwide Permit, the Commission believes that project alternatives should be explored given the sensitive aquatic life in the river. These alternatives may include upland run-off or off-line ponds, wells, treated wastewater, or combinations of those. If a surface water withdrawal is necessary, then Crooked Creek, which runs through the golf course, should be evaluated. Based on its watershed size, it presumably could supply a considerable amount of water while maintaining a base flow during low flow periods. Discharge of this creek should be estimated to verify this assumption. Moreover, using Crooked Creek instead of the river would reduce project costs since directional boring hundreds of feet under a four-lane divided highway and the river would not be necessary. If there are no feasible alternatives, then additional information about the river withdrawal is needed to ensure that it has minor, adverse effects on aquatic resources. Information such as the intake location versus the river thalweg, range of operational flow rates, minimum monthly flows for the river, duration and timing of intake operations (e.g., hours/week by season, comparison to Duke Energy releases), and water need estimates for the irrigation are needed to understand the potential losses of aquatic life from entrainment/impingement. Moreover, aquatic life impinged on intake screens do not survive unless there are frequent flow stoppages or backwash mechanisms to release them. Cleaning is needed to remove other debris as well, particularly in the fall. Information about back washing or cleaning methods is needed to understand the potential losses of aquatic life from impingement. The Commission cannot provide a thorough review of the project at this time and requests that the information needs and issues outline above be addressed. The Commission also requests the opportunity to comment further on this project if additional information becomes available or if the decision is made to act on the permit request with the information that is currently available. Thank you for the opportunity to review and comment on this permit action. If there are any questions regarding these comments, please contact me at (828) 452-2546 extension 24.
