GEOTECHNICAL, ENVIRONMENTAL AND CONSTRUCTION MATERIALS CONSULTANTS Subject: Rogers Dam Remediation Plan 401 Water Quality Certification Pre - Construction Notice To Whom It May Concern: 201311-C.32 I LN V 2 6 20,3 _ - WA AUTY Attached please find five copies of the completed Pre - Construction Notification (PCN) Form and the $240 Application Fee for the above referenced project. Work at this dam has been previously permitted under the Army Corp of Engineers Nationwide Permit (NWP) No. 18; the current maintenance work at the site is expected to be permitted under NWP No. 3. It is our understanding that the cumulative impacts of the previous and current remediation work being done at the project site necessitates that the Owner now apply for a 401 Permit through the NC Division of Water Quality. Rogers Dam is an earth impounded dam located in Macon County, North Carolina, northwest of downtown Franklin, in the Little Tennessee River Basin. A location map of the project area is attached. The dam is approximately 36.5 -feet high, has a crest length of 225 -feet and a drainage area of 79- acres. The surface area of the impoundment is 1.3 -acres or 19 acre -feet. The purpose of this project is to provide additional spillway capacity for the dam. Approximately 0.5- acres of the existing dam and spillway are being disturbed during this maintenance work. Previous project work at the site, in 2008 under NWP No. 18, included the installation of 120 -feet of culvert. This project involves the impact of an additional 30 -foot of streambank immediately downstream of the spillway to minimize further eroding of the stream bank. The project also includes the installation of a new siphon to replace the existing one, as well as installation of a new overflow spillway. A copy of the project plans is included with this PCN. The Army Corp of Engineers Regional Asheville office has been contacted regarding this project. On September 23, 2013 a PCN has been submitted to them with appropriate notifications to the following agencies: Endangered Species and Designated Critical Habitat On July 30, 2013 the Asheville Field Office of the US Fish and Wildlife Service was contacted to determine whether any endangered species or critical habitat might be affected by the proposed 130 OVAL ROAD, SUITE 200 PHONE (828) 277 -0100 ARDEN, NORTH CAROLINA 28704 FAX (828) 277 -0110 NIL K", project. The project location was reviewed with Mr. Bryan Tompkins of that office and he determined that the project will have no effect on listed species. North Carolina Wildlife Resources Commission Mr. David McHenry, the Mountain Region Coordinator for the North Carolina Wildlife Resources Commission was contacted and requested a cold -water release from the impoundment. As required, a copy of the ACOE PCN was submitted to his office for review and approval from that office has been received. Historical or Prehistorical Cultural Resources There are no apparent historical buildings or structures or archaeological sites located within or immediately adjacent to the project area. However, a review of the North Carolina SHPO HPOWEB GIS Service (http: / /gis.ncdcr.gov /hpoweb /) indicates Rogers Dam is located approximately 4,500 feet upstream of the first of several surveyed -only historical structures. A Section 106 Project summary has been submitted to the State Historic Preservation Office and approval from that office has been received. Flood Zone Designation A copy of the existing HEC -RAS model was obtained from the North Carolina Floodplain Mapping Program. Based on this model, the project does not occur in a FEMA- designation 100 -year floodplain; There are no permits required by the Town of Franklin or Macon County. Please let either of the undersigned know if there is any additional information you need or if there is anything we can do to assist moving the permit process forward as quickly as possible.
