(15A NCAC 02H .0506(b)(5)] Geyer Morris Company McRae Farms, LLC individual Certification #4072 Page 5 of 11 September 27, 2016 5. The applicant has agreed to construct a storm,water outlet in the northwest corner of the property that serves as an outlet for a portion of the stormwater treatment system and further hydrates the existing headwater wetland complex, The outlet is approved by the Division, provided that State and Local authorities approve the design. If the stormwater outlet cannot be permitted or constructed, the permit must be modified. The final plans approved by the State or Local authorities will be forwarded to the Wilmington Regional Office before construction can begin, 6. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Pre -Construction Notification for this project. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices shall be performed so that no violations of state water quality standards, statutes, or rules occur. Approved plans and specifications for this project are incorporated by reference and are enforceable parts of this permit. [15A NCAC 02H .0501 and .0502] 7. Sediment and Erosion Control Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices. If applicable, the project must comply with the specific conditions and requirements of the NPDES Construction Stormwater Permit issued to the site and the following requirements [15A NCAC 02H .0506(b)(3) and (c)(3)]: a. Design, installation, operation, and maintenance, of the sediment and erosion control measures must be such that they equal or exceed the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor -owned or leased borrow pits associated with the project. b. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. c. Reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act and the Mining Act of 1971. & Sufficient materials required for stabilization and/or repair of erosion control measures and stormwater routing and treatment shall be on site at all times. e. For PNA, SA, HQW waters. The sediment and erosion control designs must comply with the requirements set forth in 15A NCAC 04B.0124 Design Standards in Sensitive Watersheds. Geyer Morris Cornpany McRae Farms, LLC Individual Certification #4072 PaBe 6 of 11 September 27, 2016 Exceptions to this condition require application submittal to and written approval by the Division. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, then design and placement of temporary erosion control measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands, stream beds, or banks, adjacent to or upstream and downstream of the above structures. All sediment and erosion control devices shall be removed and the natural grade restored within two (2) months of the date that the Division of Energy, Mineral and Land Resources (DEMLR) or locally delegated program has released the specific area within the project. [15A NCAC 02H .0501 and .0502) 9. Appropriate measures should be installed prior to any land clearing activities to protect waters and wetlands from turbidity and/ or sedimentation. These measures should be routinely inspected and properly maintained, and excavated materials should be contained outside the wetland boundary. Excessive silt and sediment loads can have numerous detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. [15A NCAC 02H .0506 (b)(3) and (c)(3)] 10. Natural fiber matting is recommended for slope stabilization around wetland areas over plastic matting that can entrap small animals. (15A NCAC 02H .0506(b)(2)] 11. Protective Fencing All wetlands, streams, surface waters, and riparian buffers located within 50 feet of the construction area on the project site shall be clearly marked (e.g. orange fabric fencing) prior to any land disturbing activities and must be maintained on the property until the project phase is completed. [15A NCAC 02H .0506 (b)(2) and (c)(2) and 15A NCAC 02H .0507 (c)] 12. Construction Plans Any final construction plans for this project must include or reference the application and plans approved by the Division under this authorization letter and certification. The applicant will also be required to evaluate all acquired permits to assure that they are consistent and all relative impacts are accounted for and shown on the construction plans, Any modification to these approved plans (dated 9/13/16) must be approved by the Division prior to implementation/construction. [15A NCAC 02H .0502 (b) and 15A NCAC 02H ,0506(4)) 13. Work in the Dry All work in or adjacent to stream waters shall be conducted so that the flowing stream does not come in contact with the disturbed area. Approved best management practices from the most current version of the NC Sediment and Erosion Control Manual, or the NC DOT Geyer Morris Company McRae Farms, LLC Individual Certification #4072 Page 7 of 11 September 27, 2016 Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams, and other diversion structures shall be used to minimize excavation in flowing water. Exceptions to this condition require application submittal to and written approval by the Division. 14. Culverts Design and placement of the culvert and other structures shall be installed in such a manner that the original stream profiles are not altered (i.e., the depth of the channel must not be reduced by a widening of the streambed). Existing stream dimensions (including pattern and profile) are to be maintained above and below locations of each culvert. The structures shall be designed and installed to allow for fish and other wildlife movement as well as prevent headcutting of the stream. The applicant may be required to provide evidence that the equilibrium has been maintained if requested in writing by the NCDWR. [15A NCAC 02H.0506(b)(2)) Unless otherwise approved in this certification, placement of culverts and other structures in open waters and streams, shall be placed below the elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow passage of water and aquatic life. Design and placement of culverts and other structures including temporary erosion control measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands or streambeds or banks, adjacent to or upstream and downstream of the above structures. The applicant is required to provide evidence that the equilibrium is being maintained if requested in writing by the NCDWR. If this condition is unable to be met due to bedrock or other limiting features encountered during construction, please contact the NCDWR for guidance on how to proceed and to determine whether or not a permit modification will be required. [15A NCAC 02H.0506(b)(2)) If multiple pipes or barrels are required, they shall be designed to mimic natural stream cross section as closely as possible including pipes or barrels at flood plain elevation and/or sills where appropriate. Widening the stream channel should be avoided. Stream channel widening at the inlet or outlet end of structures typically decreases water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage, [15A NCAC 02H.0506(b)(2)] Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed. (15A NCAC 02H.0506(b)(2)) 15. Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately accommodate high water or flood conditions. Additionally, when roadways, causeways, or other fill projects are constructed across FEMA -designated Geyer Morris Company McRae Farms, LLC Individual Certificatiori 44072 Page 8 of 11 September 27, 2016 floodways or wetlands, openings such as culverts or bridges must be provided to maintain the natural hydrology of the system as well as prevent constriction of the floodway that may result in destabilization of streams or wetlands. Culverts in wetlands are to be laid across natural ground level and do not require rip rap unless flows are to exceed 2 cfs. If the culverts are to be buried, due to cover constraints, the excess excavation areas are to be restored to original grade and rip rap shall be "keyed in" and restricted to the area directly impacted by the approved construction activity. The establishment of native, woody vegetation and other soft stabilization techniques must be used where practicable instead of rip rap or other bank hardening methods. On-site field adjustments of the culverts placements may be necessary to correctly install the done for the project, [15A NCAC 02H.506 (b)(2)] 16. The applicant shall require its contractors and/or agents to comply with the terms and conditions of this permit in the construction and maintenance of this project, and shall provide each of its contractors and/or agents associated with the construction or maintenance of this project with a copy of this Certification. A copy of this Certification, including all conditions shall be available at the project site during the construction and maintenance of this project. [15A NCAC 02H .0507 (c) and 15A NCAC 02H .0506 (b)(2) and (c)(2)] 17. Construction Stormwater Permit NCGO10000 An NPDES Construction Stormwater Permit is required for construction projects that disturb one (1) or more acres of land. This Permit allows stormwater to be discharged during land disturbing construction activities as stipulated in the conditions of the permit. If your project is covered by this permit, full compliance with permit conditions including the erosion & sedimentation control plan, inspections and maintenance, self-monitoring, record keeping and reporting requirements is required.

If concrete is used during the construction, then all necessary measures shall be taken to prevent direct contact between uncured or curing concrete and waters of the state. Water that inadvertently contacts uncured concrete shall not be discharged to waters of the state due to the potential for elevated pH and possible aquatic life/fish kills. [15A NCAC 02B .0200] 19, All backfill will consist of clean, earthen material free of any pollutants except in trace quantities. Metal products, organic materials, rock, concrete, bricks, or other non -earthen debris shall not be used. (15A NCAC 02H .0506(b)(2) and (3) and (c)(2) and (3)] Geyer Morris Company McRae Farms, LLC Individual Certification 44072 Page 9 of 11 September 27, 2016 20. Fueling, lubrication and general equipment maintenance should not take place within 50 fe of a waterbody or wetlands to prevent contamination by fuel and oils. [15A NCAC 02H .0501 (b)(3) and (c)(3) and 15A NCAC 0213.0200 (3)(f)] 21. All mechanized equipment operated near surface waters or wetlands will be regularly inspected and maintained to prevent contamination of waters and wetlands from fuels, lubricants, hydraulic fluids or other potential toxic chemicals.

Temporary Impacts Upon restoration of temporary impacts to wetlands, streams, and/or buffers, all restored areas shall be monitored quarterly for at least two years with photo documentation. The monitoring may be extended up to another 3 years if the restoration sites have not adequately recovered. (15A NCAC 02H .0506 (b)(2) and (c)(2) and 15A NCAC 02H .0507 (c)] 23. Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, waters and protective buffers within the project boundaries in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place at the time of recording of the property, or of individual lots, whichever is appropriate. A sample deed notification can be downloaded from the 401 &Buffer Permitting Branch website at http://portal.ncdenr.org/web/wq/swp/"ws/401/certsandpermits/apply/forms.
