State Project No. 40237.1.2, TIP No. R- 3300. Debit $570.00 from WBS No. 40237.4.S1 References: Section 404 Individual Permit signed August 10, 2017 (SAW-2007-1386) for U- 4751 & R-3300 Section 401 Water Quality Certification issued June 5, 2017 (20161268) for U- 4751 & R-3300 DCM Federal Consistency CD17-018 The purpose of this letter is to request modification of the Clean Water Act (CWA) Section 404 Individual Permit (IP) and Section 401 Water Quality Certification for R-3300 to authorize impacts for the construction of the Beane Mitigation Site in New Hanover County. Credit generated from this mitigation site will solely be used to provide mitigation for authorized impacts associated with the R-3300 (Hampstead Bypass) project. The Beane Property Wetland Mitigation Site (Site, Project) is located within US Geological Survey (USGS) Hydrologic Unit (HU) 03030007 and NC Division of Water Resources (DWR) Cape Fear sub-basin 03-06-23, just east of Island Creek and south of the Cape Fear River. The Site is situated within the Middle Atlantic Coastal Plain and Carolina Flatwoods Level III and Level IV US Environmental Protection Agency (USEPA) Ecoregions, respectively. The Site is located approximately 0.6 miles southwest of the New Hanover / Pender County line and State Road 1572 / 1336 (Sidbury Road) and 1.6 miles north of Scotts Hill (Figure 1). R-3300 Beane Mitigation Site Page 2 of 3 The Site encompasses 312.9 acres under the ownership of the N.C. Department of Transportation (NCDOT). Of this total, approximately 3.9 acres are part of an easement held by the Piedmont Natural Gas Company, Inc. The remaining 309.0 acres will be described in this document and be used to provide mitigation for authorized jurisdictional impacts associated with R-3300 (Hampstead Bypass). The over-arching goal of the Project is to improve the overall quality of the non-riparian and riparian wetlands by restoring/enhancing the hydrology and vegetative conditions that have been altered over the last century. The removal and conversion of existing ditches, culverts, roads, and spoil piles into functional wetland areas will provide greater on-site water holding capacity that will promote denitrification and filtration. This will ultimately help attenuate flows and provide reductions in nutrients and sediment leaving the Site. The conversion of the existing pine plantations to native plant communities will also provide greater species diversity and long-term ecological benefits to both plants and animals that inhabit the Site. The proposed wetland mitigation Project will provide approximately 79 acres of wetland restoration, 78 acres of wetland enhancement, and 31 acres of wetland preservation. Mitigation units presented in table below are projections based on mitigation design. Upon completion of site construction, the project components and unit data will be adjusted, if necessary to be consistent with the wetland mitigation units determined and approved by the USACE for the site.
