4a. 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 existing conditions at the NIH/EPA campus (site) are an institutional campus. The developed facilities are accessed through paved interior roads and parking. the central feature of the
site is Discovery Lake. The lake is fringed with wetlands and a paved walking path. The existing vegetation is generally mixed hardwoods and pines. Turfand emergent wetland vegetation
comprise most of the veg. community adjacent to the lake.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past? *
Yes No Unknown
4f. List the total estimated acreage of all existing wetlands on the property:
10
4g. List the total estimated linear feet of all existing streams on the property:
5,000
4h. Explain the purpose of the proposed project:*
The project purpose is to rehabilitate the Lake Discovery Dam to current safety standards and to provide shoreline protection in the form of rip rap, stone walls and vegetation.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
installation of the slip line repair pipes. Construct a temporary cofferdam, approx. 150 ft long x 20 ft wide x 4 ft tall, using earth materials obtained from below normal pool to ensure the
work area is dry. Upon completion of the slip line repair, the cofferdam earthen materials will be redistributed back to the area below normal pool. Addition of rip rap stone for wave armor
on the upstream dam slope.
Lake Aeration - Temporary use of an aeration system with approx. 1200 linear feet of aeration tubing leading to 10 aeration diffusers to ensure waters drained from the bottom of the lake
are not oxygen deprived and species in the outfall stream are not harmed.
Shoreline Stabilization - Installation of vegetative, rip rap, and stone retaining wall sections to stabilize eroded sections around the lake perimeter. Approx. 500 I.f vegetative, 750 I.f rip rap,
and 1000 I.f. stonewall.
Lake Aeration - are proposed to be temporarily placed within the lake. The tubes will be pressurized via a manifold on the northwestern portion of the shoreline. The tubes will disperse
atmospheric air into the lake bottom to improve low oxygen levels in the water prior to it being drained from the lake. Aeration activities are estimated to begin in March 2024 and
anticipated to proceed for approx. 1 month.
Dam and Spillway - The proposed slip line repair is a non-invasive method to restore the principal spillway and bottom drain conduits to permanent service. Pipe repair activities are
estimated to begin in April 2024 and will proceed for approx. 2 months. The wave protection armor on the upstream face of the dam is required by NC DEQ for High Hazard dams and will
be constructed of riprap beginning approx. May 2024 and proceed for approx. 1 month.
Shoreline Stabilization - Portions of the shoreline of Discovery Lake are eroding and sloughing into the lake. Wetland vegetation, rip rap and stone walls are proposed to alleviate erosion
along the shoreline. Heavy equipment and hand tools are proposed for this work.
For the fish removal, the plan is as follows:
1. Lower lake level several feet
2. Shock fish to get a sampling (this will help determine the amount of Rotenone to use)
3. Keep lake level down several feet, close valve, apply Rotenone one evening to kill all fish (the lowered pool will keep Rotenone from escaping downstream)
4. The next morning, use boats to collect fish and haul off site in trucks.
5. Allow several days duration for Rotenone to dissipate, test for when levels are safe to release water.
6. Drain lake entirely.
5. Jurisdictional Determinations
5a. Have the wetlands or streams been delineated on the property or proposed impact areas?*
Yes
