EASLEY LYNDO TIPPETT GOVERNOR SECRETARY July 2, 2007 Mr. William Wescott Mr. Stephen Lane U. S. Army Corps of Engineers Division of Coastal Management Regulatory Field Office N. C. Dept. of Env. & Natural Resources „ r Post Office Box 1000 400 Commerce Avenue ?J Washington, NC 27889-1000 Morehead City, NC 28557 Dear Sirs: Subject: Request for Modification of 404 Individual Permit, 401 Water Quality Certification Permit, Tar-Pamlico Buffer Authorization, and CAMA Major Development Permit for the proposed Washington Bypass. US 17 From South of SR 1149 (Price Road) to North of SR 1509 (Springs Road). TIP Number: R- 2510B, Federal Aid Project MAF-75-3(26). Debit $475 for WQC Modification from WBS Element No. 34440. 1.1 Reference: USACE Action ID 199301143 DWQ Project No. 050785, WQC No. 3527 CAMA Permit No. 29-07 The North Carolina Department of Transportation (NCDOT) is requesting a modification to Permit No. 199301143 for wetland and surface water impacts associated with R-2510B. The following presents revised impact calculations due to the need for a slightly wider clearance limit for construction of the main bridge over a portion of the extensive floodplain wetlands. Additionally, temporary use of Shuggart Swamp Mats and additional clearing at the north end of Site 6 is requested to initiate construction of the bridge to address fish moratorium requirements. Included in this package are revised wetland impact calculations and revised drawings for Site 6. The revised design does not compromise NCDOT's compliance with the existing permit conditions. The revision has been evaluated for compliance with the avoidance/minimization criteria and is in compliance with all previous issues, including the following: • Protected Species • Aquatic Life passage • FEMA compliance • Cultural Resources Summary of Changes The following permit modification addresses impacts at Site 6. Hand clearing in the wetlands has increased 0.32 acres at the south end and 0.08 acres at the north end. There are no changes to MAILING ADDRESS: TELEPHONE: 919-733-3141 LOCATION: NC DEPARTMENT OF TRANSPORTATION FAX: 919-733-9794 TRANSPORTATION BUILDING PROJECT DEVELOPMENT AND ENVIRONMENTAL ANALYSIS 1 SOUTH WILMINGTON STREET 1548 MAIL SERVICE CENTER WEBSITE.

General Proiect Description The NCDOT proposes to improve existing US 17 to a high speed, multi-lane highway that bypasses the City of Washington. R-2510B will include the relocation or widening of approximately 6.8 miles of US 17, starting within Beaufort County, from south of Price Road (SR 1149) south of Chocowinity, and ending north of Springs Road (SR 1509) north of Washington. The proposed roadway will be a four-lane, divided highway, with grass shoulders and ditches, and a 46-foot wide grassed median. The median will be reduced to a 10-foot median divided by a barrier on the 2.89 mile four-lane freeway bridge that will span the Tar River and the frequently inundated forested wetlands adjacent to the Tar River. The project is located in the Tar-Pamlico River Basin with a Hydrologic Unit Code of 03020104. Summary of Impacts to Waters of the U.S. Proposed impacts to jurisdictional areas of R-2510B consist of 7.92 acres of wetlands, 0.38 acre of surface waters, and 2,368 linear feet of stream channels. Wetland impacts consist of 6.04 acres of riverine wetlands and 1.88 acres of non-riverine wetlands. PERMITTING ACTIVITY TO DATE Clean Water Act Section 404 Individual Permit The project received a Clean Water Act Section 404 Individual Permit (USACE Action ID # 199301143) from the U.S. Army Corps of Engineers (USACE) Wilmington District on November 28, 2005. The original Individual Permit application was dated May 3, 2005 and a Revised Individual Section 404 Permit Application was submitted on August 5, 2005. This permit authorized construction for Section R-2510A, and stipulated that construction on R- 2510B should not begin until final design had been completed and plans had been approved by the District Engineer. A permit modification for revised impacts based on detailed design for R- 2510B was submitted on November 13, 2006. On January 17, 2007 the USACE issued a permit modification. A second permit modification was submitted on June 1, 2007, to cover minor changes observed during final design. Section 401 Water Ouality Certification The project received a Section 401 Water Quality Certification (DWQ Project No. 050785, WQC No. 3527) from the North Carolina Department of Environment and Natural Resources, Division of Water Quality (NCDWQ) on September 6, 2005. The original application for an Individual 401 Water Quality Certification is dated May 3, 2005 and an Application Resubmittal is dated August 5, 2005. A permit modification for revised impacts based on detailed design for R-2510B was submitted on November 13, 2006. On February 13, 2007 the NCDWQ issued a modification of Certification 3527. A second permit modification was submitted on June 1, 2007, to cover minor changes observed during final design. Coastal Area Management Act (CAMA) Maior Development Permit A Consistency Certification was issued by North Carolina Department of Environment and Natural Resources Division of Coastal Management (DCM) on October 31, 2005. The proposed R-2510B section impacts the Public Trust Area and Public Trust Shoreline CAMA AECs where it crosses the Tar River. A CAMA Major Development Permit Application was submitted to DCM on November 13, 2006. A permit was issued by DCM on March 6, 2007. 2 PROPOSED CHANGES The attached permit modification package includes drawings depicting proposed changes for R- 2510B at Site 6. Wetlands Changes at Site 6 are as follows. There is an increase of 0.32 acres of hand clearing at the south end of the wetlands. This increase is necessary' to accommodate slightly longer Launching Gantry support beams at the south end of the bridge then initially anticipated. The Launching Gantry support beams are the transverse beams that support the Launching Gantry equipment during the top-down bridge construction. To construct the skewed piers required at the crossing of existing US 17 it has been determined that these support beams need to be 138 feet in width. To provide I foot of clearance on each side of the beam it will be necessary to clear a 140-foot wide corridor. Currently the proposed clearing width is 133 feet. Therefore, an additional 7 feet (3.5 feet on each side) of vegetation needs to be removed to allow for this clearance. Once the gantry has passed the US 17 skewed piers, the supports can be shortened to within the 133-foot clearing limit. This additional clearing would extend from - Sta. 325+50 through bent 17 (- sta. 344+00). This is a total bridge length of 1850 feet of which about 1600 feet is woodland. At the north end of Site 6, Shuggart Swamp Mats are proposed to be used to initiate bridge construction while the Launching Gantry is being constructed. This is necessary to begin bridge construction on schedule and address the fish moratorium requirements at Kennedy's Creek. The mats will cover an area of 0.80 acres. The majority of the area that will be covered by the mats is already permitted for hand clearing. An additional 0.08 acres of hand clearing will be required to accommodate the mats. No mechanized clearing will be performed. The mats will be removed once construction is complete. Wetlands at Site 6 are riverine wetlands. Streams There are no changes to impacts to jurisdictional streams due to this permit modification. Riparian Buffers Impacts to Tar-Pamlico riparian buffer have not changed. REGULATORY APPROVALS The NCDOT respectfully requests that the referenced Section 404 Permit be modified to reflect the changes in jurisdictional impacts as outlined in this letter and presented in the attached drawings. The NCDOT is also requesting a modification to the 401 Water Quality Certification and Tar-Pamlico Buffer Authorization from the NCDWQ. In compliance with Section 143- 215.313(e) of the NCAC, we have provided a method of debiting $475, as noted in the subject line of this application, as payment for processing the Section 401 permit modification application. We are providing seven copies of this modification application to the NCDWQ for their review. Please find the attached updated permit drawings for Site 6. If you have any questions or need additional information, please call Mr. Chris Underwood at (919) 715-1451. Sincerely, 6d---? Grego J.
