All authorized activities and conditions of certification associated with the original Water Quality Certification dated September 6, 2005 and all other corresponding modifications still apply except where superceded by this certification. 2. Compensatory mitigation for impacts to 110,842.3 square feet of protected riparian buffers in Zone 1 and 74,854.0 square feet of protected riparian buffer in Zone 2 shall be required as described below, and replaces condition #10 in the 401 Water Quality Certification dated September 6, 2005: Riparian Buffer Zone Area To Be Mitigated (sq.ft) Mitigation Ratio Area to Be Mitigated (sq. ft) Zone 1 110,842.3 3:1 315,368.4 Zone 2 74,854.0 1.5:1 106,332.2 TOTAL: 421,700.6 We understand that you have chosen to perform compensatory mitigation for impacts to protected buffers through use of the North Carolina Ecosystem Enhancement Program (EEP). Mitigation for unavoidable impacts to Tar-Pamlico Riparian Buffers shall be provided in the Tar-Pamlico River Basin (HUC 03020104) and done in accordance with 15A NCAC 2B .0259. EEP has indicated in a letter dated October 27, 2006 that they will assume responsibility for satisfying the compensatory mitigation requirements for the above-referenced project, in accordance with the Tri-Party MOA signed on July 22, 2003 and the Dual-Party MOA signed on April 12, 2004. 2. Compensatory mitigation for impacts to 7.93 acres of jurisdictional wetlands shall be done. Total mitigation shall be provided as described below, and replaces condition #11 in the 401 Water Quality Certification dated September 6, 2005: Wetland Type Area ac Riparian Wetlands Miti ated Onsite Area To Be Mitigated Offsite Mitigation Ratio Acres To Be Mitigated ac Riparian 6.04 0.70 5.34 2:1 10.68 Non-Riparian 1.88 0 1.88 2:1 3.76 TOTAL: 14.44 Offsite Compensatory Mitigation Compensatory mitigation for 10.68 acres of riparian and 3.76 acres non-riparian wetlands not mitigated onsite shall be mitigated in Hydrologic Cataloging Unit 03020104, associated with the proposed project shall be provided by the Ecosystem Enhancement Program (EEP), as outlined in the letter dated August 4, 2005, and in accordance with the Memorandum of Agreement (MOA) between the State of North Carolina and the US Army Corps of Engineers signed on July 22, 2003. 3. Compensatory mitigation for impacts to 2,368 linear feet of streams shall be done at a replacement ratio of 1:1. Applying a replacement ratio of 1:1, total mitigation for 2,368 linear feet of streams shall be provided as described below, and replaces condition #12 in the 401 Water Quality Certification dated September 6, 2005: Offsite Compensatory Mitigation Compensatory mitigation for the unavoidable impacts to 2,368 linear feet of streams in the Hydrologic Cataloging Unit 03020104 associated with the proposed project shall be provided by the Ecosystem Enhancement Program (EEP), as outlined in the letter dated August 4, 2005, and in accordance with the Memorandum of Agreement (MOA) between the State of North Carolina and the US Army Corps of Engineers signed on July 22, 2003. 3. The post-construction removal of any temporary bridge structures must return the project site to its preconstruction contours and elevations. The impacted areas shall be re-vegetated with appropriate native species. 4. Prior to planting any of the vegetation for the wetland restoration sites located at the Osprey Seafood mitigation site and the Packing House Road mitigation site, a planting plan shall be submitted to, and approved by, the NC Division of Water Quality. 5. During construction of the Osprey Seafood and Packing House Road mitigation sites, the areas to be restored shall be graded to an elevation that approximates adjacent wetlands, and then ripped to promote vegetation re-establishment. 6. For the aforementioned wetland mitigation sites (the Osprey Seafood and Packing House Road mitigation sites), success shall be tracked over a 3-year period. The NCDOT shall submit an annual summary report (including pictures of the sites) at the end of each of the first two years after the completion of the project. The report shall discuss the site's vegetative and hydrologic changes. This report can be qualitative in nature and is in lieu of the usual quantitative hydrology and vegetative success criteria. At the end of the third year after project completion, the NCDOT will coordinate a field visit to the sites, at which time the DWQ will determine the success of the mitigation, and the sites may be declared successful with written approval from the NC Division of Water Quality. If, at the end of the 3-year monitoring period, the NC Division of Water Quality feels that the success cannot be determined or has not been achieved, then the NCDOT shall coordinate field visits on an annual basis until the NCDWQ is satisfied that the sites are successful. 7. Bridge deck drains should not discharge directly into the stream. Stormwater should be directed across the bridge and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes, vegetated buffers, etc.) before entering the stream. Please refer to the most current version of Stormwater Best Management Practices. 8. Two copies of the final construction drawings shall be furnished to NCDWQ Central Office prior to the pre-construction meeting. The permittee shall provide written verification that the final construction drawings comply with the permit drawings contained in the application dated November 13, 2006. Any deviations from the approved drawings are not authorized unless approved by the NC Division of Water Quality. 9. Upon completion of the project, the NCDOT Division Engineer shall complete and return the enclosed "Certification of Completion Form" to notify DWQ when all work included in the 401 Certification has been completed. Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal and/or civil penalties. This Certification shall become null and void unless the above conditions are made conditions of the Federal 404 and/or Coastal Area Management Act Permit. This Certification shall expire upon the expiration of the 404 or CAMA permit. If this Certification is unacceptable to you have the right to an adjudicatory hearing upon written request within sixty (60) days following receipt of this Certification. This request must be in the form of a written petition conforming to Chapter 150B of the North Carolina General Statutes and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. If modifications are made to an original Certification, you have the right to an adjudicatory hearing on the modifications upon written request within sixty (60) days following receipt of the Certification. Unless such demands are made, this Certification shall be final and binding. This the 24th day of January 2007 DIVISION OF WATER QUALITY Alan W. Klimek, P.E. Director Modification to WQC No. 3527
