4h. Explain the purpose of the proposed project:*
The Walker Pond ves constructed some time in the 1960/1970s. It is somewhat irregularly shaped; approximately 0.1 acres in size (surface area). Maximum water depth varies between
4.5 - 5.5' with significant floc and sediment thickness at the upstream end; storage volume capacity is an issue. The dam height is -8.5' on the downstream side. Geotechnical
investigation shows the dam was constructed of poorly suited materials (gravely and sandy silt), likely those excavated to create the pond and not properly compacted. The dam crest
has a variable width and is not level. There are currently three areas of leakage through the existing dam. The pond riser is clogged and submerged (-10-12") and undersized, as are
the two 4" emergency spillway pipes with inadequate freeboard. Water was observed flowing through the leakages and around one of the emergency spillway pipes after small storm
events in fall 2020. Evidence of scour and information provided by the owner indicates overtopping has already occurred on at least one occasion in the past 24 months. Residential
structures are located in close proximity to the downstream end of the pond (-175' and 300'). The geotechnical engineer involved with the project anticipates dam failure is likely in the
near future. The project is complicated by the presence of the property owner's sewer line which runs through the dam, -18" (to invert) from the ground surface. The project proposes
to dewater the pond to the sediment layer using siphon/pump to an adequately sized dewatering (diveresion) basin this winter. The owners are proceeding with design and cost
estimates for removing infilled sediments and reconstructing the dam or abandoning reconstruction and proceeding with stream restoration (-125'). The PCN will be modified with
reconstruction plans under the proposed NW3 (GC4132) or modified to include coverage under NW27 (GC4134).
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
A small trachoe will be used to construct a dewatering basin on the available non -forested land adjacent and downslope of the pond. The basin will be approximately 17' x 25' x 3' (wx I x
d) with no steeper than 2:1 interior sideslopes. Excavated soils will be stockpiled on site with silt fence protection to downslope areas or spread and stabilized/seeded on the landowner's
property, at their discretion and weather dependent. An outflow weir for the basin will be constructed and lined with non -woven geotextile fabric and at least 8" of Class I riprap for outlet
protection. The soils at the proposed basin should provide good infiltration; and the basin's spillway will direct flows towards Hardin Creek, on the owner's property, with at least 100' of
forested buffer between the basin and Hardin Creek (downstream of the pond). The pond will be dewatered using a gas powered pump.
4j. Please upload project drawings for the proposed project.

r Yes f' No
O Unknown

7b. If yes, explain.
This is potentially a phased project. The owners are proceeding with design and cost estimates for removing infilled sediments and reconstructing the dam or abandoning reconstruction

Action. This IPaC key assists users in determining whether a non -Federal action may cause
"take"M of the northern long-eared bat that is prohibited under the Endangered Species Act of
1973 (ESA) (87 Stat.884, as amended; 16 U.S.C. 1531 et seq.).
Based upon your IPaC submission, any take of the northern long-eared bat that may occur as a
result of the Action is not prohibited under the ESA Section 4(d) rule adopted for this species at
50 CFR §17.40(o). Unless the Service advises you within 30 days of the date of this letter that
your IPaC-assisted determination was incorrect, this letter verifies that the Action is not likely to
result in unauthorized take of the northern long-eared bat.
Please report to our office any changes to the information about the Action that you entered into
IPaC, the results of any bat surveys conducted in the Action area, and any dead, injured, or sick
northern long-eared bats that are found during Action implementation.
If your Action proceeds as described and no additional information about the Action's effects on
species protected under the ESA becomes available, no further coordination with the Service is
required with respect to the northern long-eared bat.
The IPaC-assisted determination for the northern long-eared bat does not apply to the following
ESA -protected species that also may occur in your Action area:
■ Blue Ridge Goldenrod, Solidago spithamaea (Threatened)
■ Bog Turtle, Clemmys muhlenbergii (Similarity of Appearance (Threatened))

12/03/2020 IPaC Record Locator: 336-24528917
■ Carolina Northern Flying Squirrel, Glaucomys sabrinus coloratus (Endangered)
■ Gray Bat, Myotis grisescens (Endangered)
■ Heller's Blazingstar, Liatris helleri (Threatened)
■ Roan Mountain Bluet, Hedyotis purpurea var. montana (Endangered)
■ Spreading Avens, Geum radiatum (Endangered)
■ Spruce -fir Moss Spider, Microhexura montivaga (Endangered)
■ Virginia Big -eared Bat, Corynorhinus (=Plecotus) townsendii virginianus (Endangered)
You may coordinate with our Office to determine whether the Action may cause prohibited take
of the animal species listed above.
[1]Take means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to
attempt to engage in any such conduct [ESA Section 3(19)].

Please give a brief project description below.*

The Walker Pond (-0.1 ac surface area) is an on-line pond located on an
intermittent portion of Hardin Creek (C) (10-1-5). The pond was
constructed some time in the 1960s. Geotechnical investigation shows the
dam was constructed of poorly suited materials (stony loam) excavated to
create the pond. There are currently three areas of leakage through the
dam. The pond riser is clogged and undersized as are the two 4"
emergency spillway pipes with inadequate freeboard. Scour and owner
information indicates overtopping has already occurred on at least one
occasion in the past 24 months. Additionally, the pond has infilled since its
creation leading to storage volume issues. Residential structures are
located in close proximity downstream of the pond.
This project proposes slowly dewatering the pond to the sediment layer
using siphon/pump and pipe to an adequately sized dewatering (diversion)
basin over the winter 2020/2021 prior to generally rainy spring and early
summer months. The geotechnical engineer involved with the project
anticipates dam failure is likely in the near future. The owners are
proceeding with design and estimates for reconstructing the dam or
abandoning reconstruction and proceeding with stream restoration (-126).
The subsequent PCN for this project will be modified with reconstruction
plans under NW3 (GC4132) or modified to a NW27 (GC4134).
