The specific location where the work is planned is on SR 1362 (Big Horse Creek Road) over Big Horse Creek in Ashe County, North Carolina. The geographic coordinates (in decimal degrees) are 36.5719° N and -81.56019° W. Your notification indicated that you intend to permanently impact 35 linear feet of jurisdictional stream channel associated with the placement of the bridge abutment and bank stabilization. The notification also indicates you intend to temporarily impact 148 linear feet of jurisdictional stream channel associated with dewatering activities and the installation of temporary work pads. Based on the information provided in your application, including Attachment G (Low/Minimum Impact Bridge Project Data Sheet) of the 2010 Low Impact Bridge Replacement Document, your work is authorized by Nationwide Permit (NWP) 3 for Maintenance Activities provided it is accomplished in strict accordance with the attached conditions, Attachment J (Standard Recommendations of Small Bridge Replacements in Trout Waters) and your submitted description. Any violation of the attached conditions or deviation from your submitted description may subject the permittee to a stop work order, a restoration order and/or appropriate legal action. Attached is a copy of the NWP 3 and the applicable permit conditions. This verification is valid until the NWP is modified, reissued, or revoked. All of the existing NWPs are scheduled to be modified, reissued, or revoked prior to March 18, 2017. It is incumbent upon you to remain informed of changes to the NWPs. We will issue a public notice when the NWPs are reissued. Furthermore, if you commence or are under contract to commence this activity before the date that the relevant nationwide permit is modified or revoked, you will have twelve (12) months from the date of the modification or revocation of the NWP to complete the activity under the present terms and conditions of this nationwide permit. The Action Identification Number for this project is SAW-2015-00901. Activities subject to Section 404 (as indicated above) may also require an individual Section 401 Water Quality Certification. You should contact the NC Division of Water Quality (telephone: 919-807-6300) to determine Section 401 requirements. This response to your notification does not relieve the permittee of the responsibility to obtain any other required Federal, State or local approvals/permits.
