Thank you for your PCN and attached information, dated and received 5/23/2019, for the above referenced project. I
have reviewed the information and need clarification before proceeding with verifying the use of Nationwide Permit 12
(http://saw-reg.usace.army.mil/NWP2017/2017NWP12.pdf). Please submit the requested information below (via e-mail
is fine) within 30 days of receipt of this Notification, otherwise we may deny verification of the use of the Nationwide
Permit or consider your application withdrawn and close the file:
1) Your PCN included impacts to streams and wetlands, however these and other potential jurisdictional
boundaries have not been verified by the USACE. A field verification site visit has been scheduled with Mr.
George Lankford (agent) on 6/26/2019 to verify the locations of potential waters of the US. Please note that
revisions to the PCN and plans may be necessary depending on the results of the field verification;
2) Plan Sheets 14-C1 and 15-C4 indicates that rip rap will be placed at stream crossings 14-51 and 15-52. If this rip
rap is to be placed below the ordinary high water mark of these streams, then we would consider the impacts
permanent rather than temporary. Although we would not typically consider these impacts to be a permanent
loss of waters, we need to ensure that any rip rap placed in the stream bed would not be placed above the
existing stream bed grade. Further, the impacts would need to be changed from temporary to permanent on the
PCN;
3) Further, Plan Sheet 15-C4 indicates that stream crossing 15-52 would be an aerial crossing, however the profile
view does not show enough detail to indicate whether or not the sewer line will be placed high enough to pass
high flows and therefore not disrupt the flow and circulation of waters of the US. Please indicate the clearance
between the bottom of the pipe and the stream bed at this location. Per NWP Permit 12 General Condition 9,
please explain how this crossing is constructed to withstand expected high flows, as well as how the activity
meets the condition that it must not restrict or impede the passage of normal or high flows, given that the
primary purpose of the activity is not to impound water or manage high flows.
4) Plan Sheet 14-C1 and others reference "DWG No. D9" in relation to the proposed stream crossing. However, this
drawing was not included in the PCN and attachments. Please provide any relevant detail sections and
specifications, including stream impact restoration and stabilization details, seeding specifications, pump around
methodology, etc;
5) Given the proximity of known occurrences of Roanoke logperch and James spinymussel, as well as potentially
suitable habitat for the smooth coneflower within the project area, consultation is required with the USFWS
pursuant to Section 7 of the Endangered Species Act. It is our understanding that surveys for these species in
coordination with USFWS are ongoing, and the results of these surveys will be reported to the Corps and USFWS
for further evaluation during the consultation process. Please note that the Corps cannot verify the use of a
NWP until Section 7 consultation is complete.

Please let me know if you have any questions.
