This approval is for the purpose and design described in your application. The plans and specifications for this project are incorporated by reference as part of this Water Quality Certification. If you change your project, you must notify the Division and you may be required to submit a new application package with the appropriate fee. If the property is sold, the new owner must be given a copy of this Certification and is responsible for complying with all conditions. [15A NCAC 02H .0507(d)(2)]. Please understand that the waters around your project area have been identified as a Nursery Area and requests to dredge within these areas must be consistent with 15A NCAC 02B .0220; 15A NCAC 02B .0222 which requires that conditions of waters be suitable for all best uses provided for in state rule (including, at minimum: aquatic life propagation, survival, maintenance of biological integrity, and fishing, fish, and Primary Nursery Area(PNAs) wildlife; secondary contact recreation; and that activities must not cause water pollution that precludes any best use on a short-term or long-term basis. The Division supports the concerns and recommendations from the Division of Marine Fisheries and the Wildlife Resources Commission regarding new dredging within waters of designated Primary Nursery Areas. This Water Quality Certification does not relieve the permittee of the responsibility to obtain all other required Federal, State, or Local approvals before proceeding with the project, including those required by, but not limited to, Sediment and Erosion Control, Non -Discharge, Water Supply Watershed, and Trout Buffer regulations.

CONDITIONS OF CERTIFICATION [15A NCAC 02H .0507(c)]: 1. If activities must occur during periods of high biological activity (e.g. sea turtle nesting, fish spawning, or bird nesting), then biological monitoring may be required at the request of other state or federal agencies and coordinated with these activities. All moratoriums on construction activities established by the NC Wildlife Resources Commission (WRC), US Fish and Wildlife Service (USFWS), NC Division of Marine Fisheries (DMF), or National Marine Fisheries Service (NMFS) shall be implemented. Exceptions to this condition require written approval by the resource agency responsible for the given moratorium.

Surface water quality standards require that conditions of waters be suitable for all best uses provided for in state rule (including, at minimum: aquatic life propagation, survival, and maintenance of biological integrity, wildlife, secondary contact recreation, agriculture), and that activities must not cause water pollution that precludes any best use on a short-term or long-term basis. 2. The Permittee shall adhere specially to 15A NCAC 02B .0221 Tidal Salt Water Quality for Class SA Waters (3)(g) pH: shall be normal for waters in the area, which generally shall range between 6.8 and 8.5 except that swamp waters may have a pH as low as 4.3 if it is the result of natural conditions; (I) Turbidity: the turbidity in the receiving water shall not exceed 25 NTU; if turbidity exceeds this level due to natural background conditions, the existing turbidity level shall not be increased. Citation: 15A NCAC 028 .0221 Justification: Surface water quality standards require that conditions of waters be suitable for all best uses provided for in state rule [including, at minimum: aquatic life propagation, survival, and maintenance of biological integrity (including fishing, fish, and Primary Nursery Areas (PNAs)), wildlife, and secondary contact recreation]; and that activities must not cause water pollution that precludes any best use on a short-term or long-term basis. 3. The authorized boat basin shall not be dredged beyond the proposed depth and width. The area shall not be dredged to a depth deeper than the receiving water. In this case the boat basin and access channel is authorized to a maximum depth of -6 feet Mean Low Water.

The effluent water from the dredge spoil should not (if at all practicable) be released into open shellfish waters. The release of the effluent of dredge spoil from a closed shellfish area into open shellfish water will cause a (temporary) closure of that water which in turn is a degradation of waters and a violation of tidal salt water quality standards for Class SA Waters. Shellfish Sanitation (252.726.6827) and the Division of Water Resources (910.796.7215) must be notified if this is to occur. Citation: 15A NCAC 026 .0221 Justification: In order to protect against impairment of water quality standards and best usage of receiving and downstream waters, water quality based management practices must be employed to protect against direct or indirect discharge of waste or other sources of water pollution. Surface water quality standards require that conditions of waters be suitable for all best uses provided for in state rule (including, at minimum: aquatic life propagation, survival, and maintenance of biological integrity, wildlife, secondary contact recreation, agriculture, and shellfishing for marketing purposes) and that activities must not cause water pollution that precludes any best use on a short-term or long-term basis. 6. The permittee shall report to the DWR Wilmington Regional Office any noncompliance with, and/or any violation of, stream or wetland standards [15A NCAC 02B .0200], including but not limited to sediment impacts to streams or wetlands. Information shall be provided orally within 24 hours (or the next business day if a weekend or holiday) from the time the permittee became aware of the non-compliance circumstances. Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c) Justification: Timely reporting of non-compliance is important in identifying and minimizing detrimental impacts to water quality and avoiding impacts due to water pollution that precludes any best use on a short-term or long-term basis. 7. No waste, spoil, solids, or fill of any kind shall occur in wetlands or waters beyond the footprint of the approved impacts (including temporary impacts).

When applicable, all construction activities shall be performed and maintained in full compliance with G.S. Chapter 113A Article 4 (Sediment and Pollution Control Act of 1973). Regardless of applicability of the Sediment and Pollution Control Act, all projects shall incorporate appropriate Best Management Practices for the control of sediment and erosion so that no violations of state water quality standards, statutes, or rules occur.
