The project will not require a 401 Water Quality Certification. 2. The proposed project should be done in such a way as to not cause the turbidity outside the immediate construction area to exceed 25 NTU. 3. It is recommended that the dredged material be placed on the dike as near as practical to the canal such that any runoff will enter the canal and not adjacent wetlands.

PROJECT DESCRIPTION The project site consists of a 500 acre tract of land located on the eastern bank of the Northeast Cape Fear River above the City of Wilmington. A portion of the property has been isolated from the waters of the river by the creation of an impoundment utilizing a series of dikes with water control structures. When these dikes were built a canal approximately 30' wide was formed adjacent to the impoundment side of the dikes. The isolation of this area from the river has been accomplished through the use of these water control structures. This has been a critical issue since the measured increase in salinity valves has apparently affected the habitat for fresh water herbaceous well as conifer and hardwood species within the impoundment. The species found within the structure have been exhibiting a die-off until measures were taken to rehabilitate the water control structures. The applicants indicate that at the present flow is from the impoundment to the river and that no back-flow occurs. There are areas of the existing dike that are in need of repair in order to prevent their failure. The adjacent river •waters are classified as SC, Sw and are a designated nursery area. Ness Creek is classified as Sw and is considered inland waters. The applicant proposes to excavate the existing canal area, created when the dikes were first formed and to place the excavated material on the top of the existing dike from where it will be spread over the surface. A floating excavator apparatus will probably be utilized to-carry out the work. Three areas of canal will be excavated to a width of approximately 20' by a depth of approximately 61. A -total of 4,800' will be dug. One segment approximately 2,900' in length is located at the northwest portion of the impoundment. Another segment approximately 1,800' is located at the southwest and south portion of the impoundment. A final segment approximately 200' is located at the northeast portion of the dike. The material resulting from the excavation will be placed along the outer edge of the top of the dike. Approximately 11,000 cubic yards of material will be removed. The material will be used to refurbish the dikes. a Oakley Planttion - James C. Fox Page three 10. ANTICIPATED IMPACTS As initially proposed the applicant indicated that a fairly deep (101) trench would have been created within the existing canal. However at this Division's recommendation the project has been modified to reduce the width to approximately 6' deep. This should result in a significantly lessened chance of water quality degradation within the canal. Although the impoundment is now separated from the waters of the Northeast Cape Fear River and Ness Creek by the dike structure the 11404" wetlands inside the structure should not be considered isolated. The Corps has ruled on several similar sites in the past that no fill material should be placed or deposited in these wetlands. Care should be taken during the excavation of the canals to ensure that no material sloughs off into the canal or adjacent wetlands on the inner toe of the dike. Submitted by: C.
