Specifically, condition 9 of the certification details the mitigation requirements for the project. Within this condition, DWQ required 0.58-acres of wetland mitigation, which reflects a 2:1 mitigation ratio for wetland impacts. In contrast, the attached 404 approval from the Army Corps required only 1:i wetland mitigation for the project. According to the North Carolina Administrative Code, T15A: 02H .0500, guidance for mitigation, "mitigation required by the U.S. Army Corps of Engineers shall be considered to constitute the mitigation required by the certification unless the Director determines that the mitigation proposal does not meet the criteria established in Subparagraph (6) of this Paragraph." Furthermore, the guidance states that "mitigation shall not be required for impacts to Class WL wetlands of less than one acre." In consideration of the mitigation requirement set forth by the US Army Corps of Engineers in the 404 approval and the fact that wetland impacts are below the i-acre threshold, we hereby request revision of the 401 certification, condition 9, mitigation requirement for wetland impacts such that the DWQ 401 certification does not list a requirement for wetland mitigation. You will also find the attached excerpt from the NC Administrative Code with the pertinent information highlighted (p.5 of T15A 2H.0500.pdf). I appreciate your prompt attention to this matter, and will gladly discuss this at your convenience. I can be reached by email or by mobile at (919)427-7036.

Please note that this decision does not assure that the payment will be approved by the permit issuing agencies as mitigation for project impacts. It is the responsibility of the applicant to contact these agencies to determine if payment to the NC EEP will be approved. This acceptance is valid for six months from the date of this letter. If we have not received a copy of the issued 404 Permit/40t Certification within this time frame, this acceptance will expire. It is the applicant's responsibility to send copies of the 404/401/CAMA permits to NC EEP. Once NC EEP receives a copy of the 404 Permit and/or the 401 Certification an invoice will be issued and payment must be made. Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the following table. River Basin Wetlands Stream Buffer Buffer Cataloging (Acres) (Linear Feet) Zone 1 Zone 2 Unit . (Sq. Ft.) (Sq. Ft.)

The type and amount of the compensatory mitigation will be as specified in the Section 404 Permit and/or 401 Water Quality Certification, and/or CAMA Permit. The mitigation will be performed in accordance with the Memorandum of Understanding between the N. C. Department of Environment and Natural Resources and the U. S.

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 El 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: We have reviewed the "DRAFT Internal Policy, Cumulative impacts and the 401 Water Quality Certification and Isolated Wetland Programs" document prepared by the NC Division of Water Quality on October 3, 2002, version 1.6. The draft states that most residential subdivisions are unlikely to cause cumulative impacts. The Woodlands does not meet any of the three criteria of private projects that can clearly result in cumulative impacts. We anticipate that you will advise us if a qualitative or quantitative impact analysis is required. 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).

Decimal Degrees (6 digits minimum): 36.0590°N, 78.4462°W 6. Property size (acres): + 579 acres 7. Name of nearest receiving body of water: UT Brandy Creek (B;NSW); 28-29-3-(1) Page 2 of 11 8. River Basin: Tar-Pamlico (03-03-01) (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at htW://h2o.enr.state.nc.us/admin/mUs/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The site has been in agriculture for many years; prior to development, the site was supporting cattle. Land use in the vicinity of this site is a mix of residential development, agriculture, and forestland. 10. Describe the overall project in detail, including the type of equipment to be used: The project consists of the construction of a low density housing development. An infrastructure of roads servicing the development is proposed. Dam maintenance at the existing lake is also proposed to stabilize the area surrounding the outlet pipe and re-grade the emergency spillway. Heavy equipment typically used for grading and excavation will be utilized for this project. 11. Explain the purpose of the proposed work: The purpose of the proposed work is to construct an infrastructure of roads that will provide internal access for a low-density development surrounding Cedar Lake. Other impacts associated with Dam maintenance are also proposed. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, certifications or other useful information. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules. S&EC was retained in September 2004 to delineate jurisdictional wetlands and. streams on the site. On March 14, 2005, Mr. Michael Horan of the NC-DWQ confirmed the applicability of the Tar-Pamlico buffers to streams throughout the project. Due to an oversight, Mr. Horan revised the buffer letter on February 6, 2006. A copy of Mr. Horan's revised letter is attached (TPRRO#05-0070). Ms. Jean Manuel of the USACE met S&EC personnel on-site to review our delineation and determine stream importance classifications on May 18, 2005. Page 3 of 1 I V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. No future permit requests are anticipated for this project. VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: The proposed activities include impacts to jurisdictional streams and wetlands for construction of internal roads. Impact 1C will occur in order to stabilize the dam at the spillway outlet pipe on the lake. This activity is maintenance of an existing use, and should occur under NWP 3. Similarly, impact 1 B will occur to re-grade the emergency spillway for the lake. This activity is also maintenance of an existing structure, and should occur under NWP 3. Impacts 2A, 213, and 2C are buffer impact only. Impacts 3A and 3D include wetland and pond-fill, respetively. These impacts are for road construction under NWP 14. Impacts 4A and 413 are stream and wetland impacts associated with road construction under NWP 14. Impact 5A is a stream impact associated with road construction under NWP 14. 2. Individually list wetland impacts. Types of impacts include, but are not limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding. Wetland Impact Type of Wetland Located within Distance to Area of Site Number Type of Impact (e.g., forested, marsh, 100-year Floodplain Nearest Stream Impact (acres) (indicate on map) herbaceous, bog, etc.) es/no linear feet 1 B Permanent / Fill Emergent/herbaceous Yes 360' 0.1304 3A Permanent / Fill Riparian Wetland Yes 35' 0.0512 413 Permanent / Fill Riparian Wetland Yes 0 0.1131 Total Wetland Impact (acres) 0.2947 Page 4 of 11 3. List the total acreage (estimated) of all existing wetlands on the property: The site contains approximately 56 acres of jurisdictional and isolated wetlands. 4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included. To calculate acreage, multiply length X width, then divide by 43,560. Stream Impact Number indicate on ma Stream Name Type of Impact Perennial or Intermittent?

Isolated Waters Do any isolated waters exist on the property? ® Yes ? No Page 5 of 11 Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USAGE. A temporary utility line providing irrigation water to the perimeter of the site was installed during the initial phase of construction. Impacts to isolated waters are approximately 5 linear feet of stream and no isolated wetland impacts are proposed; as such, these impacts are less than the thresholds required for notification. 8. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. The proposed impacts are necessary to allow access to the southern interior of the site. Due to the presence of four perennial/important streams that bisect the southern portion of the property from south to north, access to the interior is not possible without crossing streams and wetland areas. However, in an effort to plan around jurisdictional areas, the client retained S&EC to identify wetlands and streams on the site prior to planning. The client also invited the National Audubon Society to the property prior to site planning to identify sensitive areas for conservation. S&EC met with project engineers from ESP Associates to develop an alternative that reduces stream and wetland impacts. Consequently, the client chose to bridge two wetland and stream complexes near the southern portion of the Lake and cross the lake at the existing road on the dam. Many other, large and expansive wetland areas will remain undisturbed during development. In total, approximately 55.5 acres of jurisdictional and isolated wetlands will remain undisturbed following development. Page 6 of 11 VIII. 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. 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 htip://h2o.enr.state.nc.us/ncwetlands/stn-np,ide.html. 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. The client proposes payment to NC-EEP for mitigation of resources lost to the development. An application to EEP has been submitted on behalf of the project. 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 http://h2o.enr.state.nc.us/wrp/index.htm.

If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0244, or. 0260. Buffer impacts on this project are proposed at the outlet pipe for the Dam (1 C) for dam maintenance, road construction across the existing dam (2A, 2B, and C), Bridge 2 & Road (313 and 3C), Bridge 3 Approach Culvert (4E and 4F), Bridge 3 & Road (4C and 4D), and the buffer impact associated with Culvert #25 (5B and 5C). A detailed explanation of mitigation requirements for these impacts is provided below. • Dam stabilization - Because the buffer impacts to stabilize the dam around the outlet pipe are considered maintenance of an existing structure (the dam), we do not believe buffer mitigation should be required for this impact. Page 9 of 11 • Road on top of existing Dam - Because there is an existing gravel road on the top of the dam, we discounted the impervious surface within the buffer currently occupied by the existing road (within our proposed corridor) from the proposed buffer impacts for the proposed construction. The net result is a buffer impact less than 1/3-acre and less than 150-linear feet when measured parallel to the stream. Because the net buffer impact of new construction will impact less than 1/3 acre and less than 150-linear feet of buffer (measured parallel to the stream), we do not believe buffer mitigation should be required for this impact. • Bridge 3 Approach Culvert (4E and 4F) - Because the proposed stream crossing at this location is perpendicular to the stream, and the buffer area is less than the thresholds required for mitigation, we do not believe buffer mitigation should be required for this impact. • Bridge 3 & Road - Because the proposed stream crossing at Bridge 3 is perpendicular to the stream, and bridges are "allowable" activities within the buffer regulations, we do not believe buffer mitigation should be required for this impact. Moreover, the proposed buffer area impact is less than the thresholds required for mitigation. • Culvert #25 - Because the crossing at Culvert #25 is perpendicular to the stream and the buffer area for this stream crossing is less than the thresholds required for mitigation (1/3-acre and/or 150-linear feet of buffer), we do not believe buffer mitigation should be required for these impacts. • Bridge 2 & Road, Pond Fill Because the buffer impacts proposed for this area are parallel to the surface water, and the buffer impacts exceed the thresholds required for mitigation (greater than 1/3 acre of riparian buffer and greater than 150-linear feet of buffer impact) we propose payment to EEP to mitigate for 50.572.5 square-feet of riparian buffer to mitigate for these impacts. XI. XII. Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. Due to the large lot sizes, large lake, and extensive undisturbed wetland areas, we anticipated the percent impervious surface for the project will be below 20%. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. The development will connect to an existing sanitary sewer system. The municipality will ensure that this development does not exceed the available capacity of the facility. Page 10 of 11 XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .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).

FRANK-005 Dear Mr. Harrington: /- f7c "0' o/Q 4-/' ! Michael F.'Easley, Governor William G. Ross Jr., Secretary This is in response to your submission received on February 7, 2006 of plans, specifications and design data for the repair of the subject dam in compliance with the Dam Safety Law of 1967. These plans, specifications and design data were prepared under the supervision of Mr. Timothy LaBounty, PE. This letter constitutes approval of the proposal to modify the subject darn according to the plans and specifications received by this Division on February 7, 2006 with the following stipulations: 2. 3. 4. A flow of water sufficient to maintain downstream aquatic habitat must be released from the dam at all times, even during construction. Mr. Timothy LaBounty, PE shall provide engineering supervision. During construction, the Division of Land Resources may require such progress reports as are deemed necessary. Upon completion of the project, Mr. Timothy LaBounty, PE shall inspect the completed work and upon finding that the work has been done as specified and the dam is safe, shall file with the Division of Land Resources two sets of record drawings and a certificate stating that the work has been completed in accordance with approved plans, specifications and other requirements.

You must notify Mr. John Holley, PE, Regional Engineer, Land Quality Section, 3800 Barrett Drive, Raleigh, North Carolina 27609, (919) 791-4200 ten days before the start of construction. The Army Corps of Engineers and the Water Quality Section of this Department should be contacted to determine if additional permits are required. Also, the erosion and sediment control program having jurisdiction should be contacted to determine permit requirements. In any case, sediment must be prevented from entering the waters of the state or flowing onto neighboring property. The Division of Water Resources is determining the necessary minimum release for the dam. This will become a component of the approval to be issued on completion of the modifications. Construction of the modifications must begin within one year of the date of this letter or this approval is void.

In addition, the rip rap had been designed to provide energy dissipation to minimize the,potential for downstream erosion resulting from discharges from the barrel. To maintain stream impacts below permitted limits established by the Army Corps of Engineers and the N.C. Division of Water Quality, the principal spillway was modified so that it will function primarily as a low flow discharge structure for base flow and will allow minimal discharge passage during the design storm. The lower peak flow and velocity resulted in reducing the size of the energy dissipater/outlet protection at the barrel outlet to meet regulatory impact limitations. The proposed re-grading and lining of the spillway channel is necessary to minimize the potential for future erosion. The high performance turf reinforcement mat (TRM)/grass lining can accommodate the design storm calculated velocities and shear stresses in the channel section. The 20 feet long rip rap apron proposed at the brink of the existing concrete spillway is necessary for additional scour protection at the transition from the structural spillway to the TRM-lined vegetated channel.
