Please reference the 401 Water Quality Certification (Certification) issued by the NC Division of
Water Resources (DWR) on July 12, 2012 (Attachment A). The Certification authorizes 1,140 feet
of stream impacts for the purposes of stream bank stabilization on the North Toe River in Avery
County, North Carolina. As part of the Certification approval, stream/structure stability monitoring
was required for a period of three years. Monitoring was to include an as -built drawing, photo
documentation, and a narrative of findings.
The attached 2013 As -Built (Attachment B), 2014 Monitoring Year 1 (Attachment C), 2015
Monitoring Year 2(Attachment D), and 2016 Monitoring Year 3(Attachment D) reports for the North
Toe River Bank Stabilization project are being submitted on behalf of the Unimin Corporation
represented by myself
Construction of eight structures was completed during May 2013. As -built photo documentation was
completed during 2013 followed by photo documentation during May 2014, May 2015 and finally
May 2016. Results from the continued photo documentation efforts indicate that all eight
structures remain stable and are functioning as designed. This is the final monitoring report to be
submitted for the completion of the three year monitoring period from 2013 until 2016.
Please do not hesitate to contact me at 828-765-4251 extension 313 if you have any questions or
comments.
