Subject: Request for Additional Information (DWR #16-0482)
Nationwide No. 121 General Water Quality Certification No. 3884
CFPUA Blue Clay Road Force Main Project
New Hanover County, North Carolina
To Whom It May Concern:
On May 16, 2016, the Division of Water Resources (Division) requested additional information concerning the proposed
construction activities associated with the proposed Blue Clay Road Force Main PCN. A PCN package was received by
the Division on May 10, 2016 and the application was put on hold pending payment of an application fee.
The original PCN application stated impacts to wetland 3 are "permanent" impacts. This impact is the conversion of a
forested (PFO) wetland to an emergent (PEM) wetland; while the USACE classifies these as permanent impacts, the
Division classifies them as temporary. Per coordination with Ms. Sheri Montalvo and Mr. Chad Coburn of the Division, we
have clarified that this impact is being re-classified as temporary and no fee payment to the Division is needed to process
the application. A revised page 4 of the PCN application is enclosed.
Per communication with Mr. Policarpo, CFPUA has decided to use Blue Clay Road to access both sides of the pipe
during construction rather than creating temporary ford style crossings at intermittent and perennial stream crossings (S1,
S2, S3), thereby minimizing impact to these streams. Attached are replacement detail sheets (00C-14, OOC-15) for the
stream crossings, which include a pump around detail. Thank you very much for your timely review of these materials,
and please feel free to contact us with any additional questions.
Respectfully,
