David,
Thanks for your email and comments. Let me coordinate with who I need to coordinate
and I'll get back to you.

Thank you for your PCN and attached information, dated and received 6/8/2018, for the
above referenced project. I have reviewed the information and need clarification before
proceeding with verifying the use of Nationwide Permit 23 (http://saw-
reg.usace.army.mil/NWP2017/2017NWP23.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your application withdrawn and close the file: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) Although, the use of NWP 23 is requested, several propose impacts including
temporary dewatering and bank stabilization are not necessarily covered by NWP 23.
One option would be to also request to use NWPs 13 and 33 for these impacts.
However, I suggest requesting to use of NWP 14 to cover any and all impacts associated
with this project. Note that, in either case, NCDWR must be informed of any such
changes so that appropriate WQC's can be issued;
2) Given that this project is part of NCDOT's statewide road network, and the resulting
cumulative aquatic resources impacts (see the attached letters from 2004), the typical
150 linear foot stream impact threshold for compensatory mitigation does not apply. In
most cases, losses of waters require mitigation at 2:1. From the information provided it
appears that compensatory mitigation for loss of stream channel/function is required
for the Site 1 Dual 60" RCP activity. Please provide either justification that compensatory
mitigation is not warranted based on a functional assessment (i.e. NCSAM form) or
propose compensatory mitigation through the typical Mitigation Bank/NCDMS process
(including acceptance letters and perhaps combined with assessment forms if proposing
<2:1);
3) Were any habitat surveys conducted for Michaux's sumac (Rhus michauxii) or smooth
coneflower (Echinacea laevigata). Please provide additional information to aid in an
effects determination for these species.;
4) Site 3 is listed as Utility Construction. Please provide additional information
concerning the type of utility and reason for the stream impact. Further, please provide
a plan sheet that clearly shows the proposed utility location and profile of the proposed
stream impact. Lastly, is any rip rap proposed within the impact area? If so, ensure the
plan sheet shows the rip rap location and change the impact type to permanent.
Please let me know if you have any questions.
