The application provides adequate assurance that the discharge of fill material into the waters of the Tar River
Basin in conjunction with the proposed development will not result in a violation of applicable Water Quality
Standards and discharge guidelines. Therefore, the State of North Carolina certifies that this activity will not
violate the applicable portions of Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in
accordance with the application and conditions hereinafter set forth.
This approval is only valid for the purpose and design that you submitted in your modified applications dated
received June 11, 2007 and received July 9, 2007. All the authorized activities and conditions associated with the
original Water Quality Certification dated September 6, 2005, and all subsequent modifications still apply except
where superceded by this certification. Should your project change, you are required to notify the DWQ and
submit a new application. If the property is sold, the new owner must be given a copy of this Certification and
approval letter, and is thereby responsible for complying with all the conditions. If any additional wetland
impacts, or stream impacts, for this project (now or in the future) exceed one acre or 150 linear feet, respectively,
additional compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h) (6) and (7). For
this approval to remain valid, you are required to comply with all the conditions listed below. In addition, you
should obtain all other federal, state or local permits before proceeding with your project including (but not
limited to) Sediment and Erosion control, Coastal Stormwater, Non-discharge and Water Supply watershed
regulations. This Certification shall expire on the same day as the expiration date of the corresponding Corps of
Engineers Permit.
Condition(s) of Certification:
1. The only modifications to the design of the project authorized by this certification are those submitted in your
applications received June 4, 2007 and July 2, 2007. All authorized activities and conditions 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still apply except where superceded by this certification.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 105,487.5 square feet of protected riparian buffers in Zone 1 and
72,055.1 square feet of protected riparian buffer in Zone 2 shall be required as described below, and replaces
condition #2 in the 401 Water Quality Certification dated February 13, 2007:

Zone 2 72,055.1 1.5:1 108,082.7
TOTAL: 424,545.2
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 213 .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.
3. Compensatory mitigation for impacts to 7.92 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:

Compensatory mitigation for impacts to 10.68 acres of riparian wetlands and 3.76 acres of non-
riparian wetlands not mitigated onsite shall be mitigated in Hydrologic Cataloging Unit
03020104. These impacts 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.
4. 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 Noah Carolina and the US Army Corps of
Engineers signed on July 22, 2003.
5. 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.
6. 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.
7. 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.
The permittee and its authorized agents shall conduct its activities in a manner consistent with State water
quality standards (including any requirements resulting from compliance with §303(d) of the Clean Water
Act) and any other appropriate requirements of State and Federal law. If DWQ determines that such
standards or laws are not being met (including the failure to sustain a designated or achieved use) or that State
or federal law is being violated, or, that further conditions are necessary to assure compliance, DWQ may
reevaluate and modify this certification.
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.
10. A copy of this Water Quality Certification shall be posted on the construction site at all times. In addition, the
Water Quality Certification and all subsequent modifications, if any, shall be maintained with the Division
Engineer and the on-site project manager.
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, 67114 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.
