Director Division of Water Quality July 14, 2005 DWQ Project # 050885 Granville County Merriweather LLC Attn: Tim Newcomb 246 W. Millbrook Road Raleigh, NC 27619 Subject Property: Merriweather Subdivision UT to West Prong [03-04-01, 27-13-0.2, WS-IV, NSW (nutrient sensitive)] Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse River Buffer Protection Rules (15A NCAC 2B.0233) with Additional Conditions Dear Mr. Newcomb: You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact 140 feet of streams and 8,277 squar? feet (ft) of protected riparian buffers for the purpose of a residential subdivision at the subject property, as described within your application dated May 20, 2005 and received by the N.C. Division of Water Qualit? (DWQ) on May 20, 2005. After reviewing your application, we have decided that the impacts are covered by General Water Quality Certification Number(s) 3404 (GC3404). The Certification(s) allows you to use Nationwide Permit(s) 14 when issued by the US Army Corps of Engineers (USACE). This letter shall also act as your approved Authorization Certificate for impacts to the protected riparian buffers per 15A NCAC 2B .0233. In addition, you should obtain or otherwise comply with any other required federal, state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control, and Non-discharge regulations. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA Permit. This approval is for the purpose and design that you described in your application. If you change your project, you must notify us and you may be required to send us 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 conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in the attached certification and any additional conditions listed below. The Additional Conditions of the Certification are: 1. Impacts Approved The following impacts are hereby approved as long as all of the other specific and general conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are approved including incidental impacts: 401 Oversight/Express Review Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786/ FAX 919-733-6893/ Internet htta://h2o.enr.state.nc.us/ncwetlands One i Carolina Np wra!!y An Equal Opportunity/Affirmative Action Employer -500/6 Recycled/10% Post Consumer Paper Merriweather LLC Page 2 of 4 7/14/05 Amount Approved nits Plan Location or Reference Stream 140 (feet) Sheet 8 Buffers 8,277 (square ft.

Erosion & Sediment Control Practices 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 in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The 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. 3. No Waste, Spoil, Solids, or Fill of Any Kind No waste, spoil, solids, or fill of any kind shall occur in''? etlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Pre-Construction Notification. 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. 4. No Sediment & Erosion Control Measures w/n Wetlands or Waters Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project. 5. Certificate of Completion Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650. 6. Buffer Impacts The approved buffer impacts associated with the road crossing equal 140 linear feet. The Neuse Buffer Rule requires buffer mitigation for road crossings that exceed 150 linear feet or 1/3 acres of buffer impacts. The impact area includes the area of the footprint of the use and any clearing and grading activities within the riparian buffer necessary to accommodate the use. The length of buffer impact is measured parallel to the stream and includes the length of the footprint of the use and any clearing and grading activities within the riparian buffer necessary to accommodate the use. If the Merriweather LLC Page 3 of 4 7/14/05 DWQ determines that the impacts exceed 150 feet or 1/3 acre to the buffer, then buffer mitigation pursuant to 15A NCAC 02B .0233 will be required for the entire impact area. 7. Diffuse Flow All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected stream buffers and will not re-concentrate before discharging into the stream as identified within 15ANCAC 2B .0233(5). In an effort to comply with the diffuse flow provision of the Buffer Rule (15A NCAC 02B .0233(5)), you have provided the DWQ with level spreader designs dated May 2, 2005. The DWQ believes that if implemented, as per these plans, diffuse flow will be achieved. However, if diffuse flow as per 15A NCAC 02B .0233(5) is not achieved, then the DWQ shall be notified and corrective actions to restore diffuse flow shall be taken if necessary to impede the formation of erosion gullies. At no time shall stormwater from the proposed development be piped directly through the buffer without prior DWQ written authorization. 8. Protective Fencing The outside buffer, wetland or water boundary and along the construction corridor within these boundaries approved under this authorization shall be.,' clearly marked with orange warning fencing (or similar high visibility material) for the areal that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15A NCAC 2B .0233 and GC 3404. 9. Construction Stormwater Permit NCGO10000 Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General stormwater permit (NCGO10000) administered by DWQ is automatically issued to the project. This General Permit allows stormwater to be discharged during land disturbing construction activities as stipulated by conditions in the permit. If your project is covered by this permit [applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self-monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at http•//h2o enr state.nc.uslsulFor ns Documents.htm. 10. Deed Notifications Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, waters and protective buffers in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval and Authorization Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of the sample deed notification may be modified as appropriate to suit to this project. 11. Culvert Installation Culverts required for this project shall be installed in such a manner that the original stream profiles are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and Merriweather LLC Page 4 of 4 7/14/05 longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing,pipes are or become perched, the appropriate stream grade shall be re-established or, if the pipes installed in a perched manner, the pipes shall be removed and re- installed correctly. Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal and/or civil penalties. The authorization to proceed with your proposed impacts or t6 conduct impacts to waters as depicted in your application and as authorized by this Certification, shall expire upon expiration of the 404 or CAMA Permit. If you do not accept any of the conditions of this Certification (associated with the approved wetland or stream impacts), you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing. Any disputes over determinations regarding this Authorization Certificate (associated with the approved buffer impacts) shall be referred in writing to the Director for a decision. The Director's decision is subject to review as provided in Articles 3 and 4 of G.S. 1501. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act and the Neuse riparian buffer protection rule as described within 15A NCAC 2B .0233.

We also request written concurrence from the NC Division of Water Quality (NC-DWQ) that the project complies with the 401 Water Quality Certification associated with Nationwide Permit 14 and Neuse Riparian Rules. A Pre-constructionNotification Application (PCN) is-attached, as well as an agent authorization form. Location The project site is located in the headwaters of West Prong in Granville County. The site is south of SR 1715 Road and east of SR 1714 (Woodland Church Road). Figure 1 depicts the site on the applicable USGS topographic quadrangle. Proiect History S&EC delineated the jurisdictional waters on-site in November of 2004, only two perennial streams were noted. No permits have previously been issued for this project site, so no Action ID numbers currently exist. A site meeting with Eric Kulz of DWQ has been scheduled for June 9, 2005. Level spreader details and calculations for stormwater from the road are enclosed.

No impacts are proposed for general lot fill. The proposed impacts are depicted on the attached site plans and are enumerated and described in the attached PCN form. No wetland impacts are proposed for this project. The total cumulative permanent impacts for this project consist of 140 linear feet of perennial/important stream channel. Avoidance The USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and may require compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the thresholds for notification (0.10 acre) of wetlands or if a discharge causes the loss of any open waters. The applicant requested a delineation of wetlands and waters prior to site plan development in order to avoid impacts to jurisdictional areas to the maximum extent practicable. However, due to.site constraints, impacts to .a stream is necessary to access high ground lots. The applicant reduced impacts to the channel by aligning the proposed road perpendicular to the channel. Mitigation No buffer mitigation should be required because impacts are less than 150' and less than. 1/3 acre of buffer. NC-DWQ's current policy, requires mitigation for any stream channel impacts in excess of 150' perrproject. The USACE can require stream mitigation for any impact. requiring notification. Due to the avoidance of impacts and the minimization of required stream impacts, no mitigation is proposed other than avoidance is proposed. This is typically acceptable to the Corps when impacts are less than 150' for unavoidable road crossings. . Si erely, oor evin Martin President ?'•J 0...i 3" L u?

Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. Page 9 of 12 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/stnnp.ide.htmI. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. Mitigation should not be required by DWQ since impacts are below mitigation thresholds. Typically the Corps does not require mitigation for stream impacts less than 150'. 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form. For additional information regarding the application process for the NCEEP, check the NCEEP website at htlp://h2o.enr.state.nc.us/MU/index.htm. If use of the NCEEP is proposed, please check the appropriate box on page five and provide the following information: Amount of stream mitigation requested (linear feet): 0 Amount of buffer mitigation requested (square feet): 0 Amount of Riparian wetland mitigation requested (acres): 0 Amount of Non-riparian wetland mitigation requested (acres): 0 Amount of Coastal wetland mitigation requested (acres): 0 Page 10 of 12 IX.

On site subsurface sg tp is systems XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 211.0500) or any Buffer Rules? Yes ? No Is this an after-the-fact permit application? Yes ? No XIV. Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ? No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). sf ?_,o Applican Agen s Signature Date (Agent's signature i id only if an authorization letter from the applicant is provided.)

Maintenance activities shall be performed as follows: 1. After every significant runoff producing rainfall event and at least monthly: a., Inspect all level spreaders for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. 2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3. Inspect and repair the level spreaders quarterly to maintain proper functioning. 4. Remove accumulated sediment from the level spreaders semi-annually or when depth affects the functioning of the level spreaders. Removed sediment shall be disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e. stockpiling near a level spreader or stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. 5. Remove cattails and other indigenous wetland plants from the level spreaders. 6. All components of the level spreaders shall be maintained in good working order. 7. Level spreaders or other structures that provide diffuse flow shall be maintained every six months. All accumulated sediment and debris shall be removed from the structure, and a level elevation shall be maintained across the entire flow spreading structure. Any down gradient erosion must be repaired and/or replanted as necessary. I acknowledge and agree by my signature below that I am responsible for the performance of the seven maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any changes to the system or responsible party. Print name: Robert T. Newcomb Title: Manager. Merriweather. LLC Address: 246 W.
