Division of Water Quality (DWQ) on January 20, 2004 . After reviewing your application, we have decided that the impacts are covered by the General Water Quality Certification Number(s) 3374 & 3402 (GC3374 & GC3402). The Certification(s) allows you to use Nationwide Permit(s) 12 & 39 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, Non-discharge, and water supply regulations. Also, this approval will expire when the accompanying 404 permit expires unless otherwise specified in the General Certification. This approval is only valid 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). For this approval to be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. Conditions: 1. 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 DWQ has determined that your application was incomplete and/or provided inaccurate information as discussed below. The DWQ will require additional information in order to process your application to impact protected wetland, streams and/or buffers on the subject property. Therefore, unless we receive the additional information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H .0506 and 26 .0233(8) and will place this project on hold as incomplete until we receive this additional information. Please provide the following information so that we may continue to review your project. Additional Information: 1. Wetland Impact # 2 (Design) - It appears that the triple culvert design proposed will not provide for adequate aquatic life passage at low stream flow. Also, it appears that you are proposing to relocate the stream flow into the wetland. Please provide additional information clearing showing how you will provide aquatic life passage, how you will not destabilize the stream and how you will not alter the flow of the stream or wetland. 2. Diffuse Flow - All constructed stormwater conveyance outlets shall be directed to flow in a diffuse manner at non- erosive velocities through the entire protected stream buffers without re-concentrating. If this is not possible it may be necessary to provide stormwater facilities that are considered to remove nitrogen. Please provide a stormwater management plan for this project. The plan shall specify all stormwater discharge points, plan details, and calculations to indicate that diffuse flow through the protected buffers or nitrogen removal as described above will be achieved. 3. Wetland Impact #2 (No Practical Alternatives) - You stated in your letter that "if the impacts are not approved Durham will allow the use of a cul-de-sac in this location". As such, it appears that there is a practical alternative that avoids the need for this crossing and it's associated impacts. Please provide additional justification as to why this crossing cannot be avoided. A letter from the City of Durham justifying the need for the crossing may be helpful. Please respond within three weeks of the date of this letter by sending this information to me in writing and Mr. Steve Mitchell of the DWQ Raleigh Regional Office. If we do not hear from you within three weeks, we will assume that you no longer want to pursue this project and we will consider the project as withdrawn.

We also request written concurrence from the North Carolina Division of Water Quality that the project complies with the 401 Water Quality Certifications associated with Nationwide Pen-nit 39. A Pre-construction Notification Application (PCN) is attached, which includes an agent authorization form. The proposed project consists of impacts from the construction of access roads and a sanitary sewer connection for a residential housing development. The site is located on the north side of Highway 98 and the south side of Freeman Rd (SR 1846). The project lies between Fletcher Chapel Road (SR 1815) and Clayton Road (SR 1825) with the southeastern property line formed by Little Lick Creek. The site is approximately 112 acres in size, and consists primarily of pine and hardwood stands. Please refer to the attached USGS map, which displays the location of the proposed project.

Maps were sent to the USACE on October 2i, 2003 for approval. Mr. Steve Mitchell of the NC-DWQ made a site visit and confirmed the buffers on December 4, 2001. A copy of his letter is attached. The applicant requested a detailed wetland delineation and buffer evaluation on the property prior to site plan development in order to avoid jurisdictional features and riparian buffers to the maximum extent practicable. The proposed roadway will impact approximately 69 linear feet of intermittent channel. A temporary impact of 0.003 acres of jurisdictional wetlands and 30 linear feet of perennial channel is required for a sanitary sewer connection. These impacts are elaborated upon within the attached PCN form and are shown on the attached inset impact maps. The proposed road crossing (impact # 1) is necessary to gain access for the property from an existing road located east of the site. The road crossing will impact a segment of intermittent channel and associated buffers. Because the road must "tie into" an existing road east of the site, the proposed road crossing cannot be constructed perpendicular to the stream. The sanitary sewer connections (impacts ## 2 & 3) will impact 0.003 acres of jurisdictional wetlands, a segment of perennial channel, and a portion of the riparian buffer in order to connect to an existing utility line. These impacts are temporary, and are a necessary utility for the proposed development. The applicant will minimize impacts using headwalls at the proposed crossing. Following construction, the applicant will maintain riparian buffers on the stream channels as well as employ BMP devices to preserve water quality. Stonnwater will be treated or released as sheet flow (i.e. diffuse) before entering the buffers. Moreover, because this site is located within a water-supply watershed, Durliam regulations will not allow >24% impervious surface within the site. The USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification (0.10 acre). The proposed roads are necessary to access the entire property. Because the applicant has minimized impacts to the maximum extent practicable, will maintain riparian buffers, and will preserve approximately 9 acres of wetland, S&EC does not believe further compensatory mitigation should be required by the USACE. NC-DWQ's current policy requires written concurrence for stream impacts of greater or equal to 150 linear feet of stream length per project. We request written concurrence that the project complies with the 401 Water Quality Certification associated with Nationwide Permit 39. NC-DWQ's current policy does not require wetland or stream mitigation for perennial stream channel impacts below 1 acre and 150 linear feet per project. Because the total permanent impacts to perennial channels is less than 150 feet, we do not believe that stream mitigation should be required by NC-DWQ. Please note that following construction the site will contain less than 30% impervious surface. Therefore, we do not believe that this project requires a pre-approved stonnwater plan. Please call if you require any additional information or have any questions.

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.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): NA Size of watershed draining to pond: NA Expected pond surface area: NA VI. 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. A detailed delineation was conducted in order to develop a site plan that minimized impacts. Impact # 1 is necessary to access the area from the existing subdivision adjacent to the property. Due to the location of the existing road east of the proposed project, this impact could not be avoided entirely. Impacts # 2 & 3 (buffer impacts) are necessary to tie into the existing sary sewer that will service the proposed subdivision. In addition the applicant will utilize BMP_ devices for water treatment. VII. 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 March 9, 2000, 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. Page 5 of 8 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 NCWRP 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.ne.us/ncwetiands/stnngide.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. Because impacts are below the thresholds that typically require mitigation and because all wetlands will be preserved on-site, we do not believe mitigation should be required. However, if mitigation is required, we propose payment to the WRP. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wm/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): NA Amount of buffer mitigation requested (square feet): NA Amount of Riparian wetland mitigation requested (acres): NA Amount of Non-riparian wetland mitigation requested (acres): NA Amount of Coastal wetland mitigation requested (acres): NA VIII. Environmental Documentation (required by DWQ) Does the project involve an expenditure of public (federal/state) funds or the use of public (federal/state) land? Yes ? No If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No ? If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Page 6 of 8 Yes ? No ? IX. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 213 .0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 213 .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ® No ? If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Zone* Impact (square feet) Multiplier Required Mitigation 1 7224 3 NA 2 5960 1.5 NA Total 13184 NA Lone 1 extends out 3U teet perpendicular trom near bank of channel; Gone 1 extends an additional 20 feet from the edge of Zone 1. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0260. NA X. Stormwater (required by DWQ) Describe impervious acreage (both 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. The site does not currently contain impervious surface. Following construction the site will contain less than 30% impervious surface therefore we do not believe a pre-approved stormwater plan is required. Moreover, because this site is located in a water supply watershed, Durham regulations prohibit any development that exceeds 24% impervious. The applicant will provide measures to insure that diffuse flow is achieved before stormwater enters the buffers as well as maintain a riparian buffers. A stormwater management plan is attached for your review. Page 7 of 8 XI. 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. Sanitary Sewer XII. 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 XIII. 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).

The DWQ has determined that your application was incomplete and/or provided inaccurate information as discussed below. The DWQ will require additional information in order to process your application to impact protected wetland, streams and/or buffers on the subject property. Therefore, unless we receive the additional information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H .0506 and 26 .0233(8) and will place this project on hold as incomplete until we receive this additional information. Please provide the following information so that we may continue to review your project. Additional Information: 1. Wetland Impact # 2 (Design) - It appears that the triple culvert design proposed will not provide for adequate aquatic life passage at low stream flow. Also, it appears that you are proposing to relocate the stream flow into the wetland. Please provide additional information clearing showing how you will provide aquatic life passage, how you will not destabilize the stream and how you will not alter the flow of the stream or wetland. 2. Diffuse Flow - All constructed stormwater conveyance outlets shall be directed to flow in a diffuse manner at non- erosive velocities through the entire protected stream buffers without re-concentrating. If this is not possible it may be necessary to provide stormwater facilities that are considered to remove nitrogen. Please provide a stormwater management plan for this project. The plan shall specify all stormwater discharge points, plan details, and calculations to indicate that diffuse flow through the protected buffers or nitrogen removal as described above will be achieved. 3. Wetland Impact #2 (No Practical Alternatives) - You stated in your letter that "if the impacts are not approved Durham will allow the use of a cul-de-sac in this location". As such, it appears that there is a practical alternative that avoids the need for this crossing and it's associated impacts. Please provide additional justification as to why this crossing cannot be avoided. A letter from the City of Durham justifying the need for the crossing may be helpful. Please respond within three weeks of the date of this letter by sending this information to me in writing and Mr. Steve Mitchell of the DWQ Raleigh Regional Office. If we do not hear from you within three weeks, we will assume that you no longer want to pursue this project and we will consider the project as withdrawn.

W l Dear Mr. Tugwell and Mr. Dorney, On behalf of Durham Land Associates, LLC - Durham, we hereby request authorization from the US Army Corps of Engineers to use Nationwide Permit 39 to cover impacts to stream channels and jurisdictional wetlands (see attached overall map). We also request written concurrence from the North Carolina Division of Water Quality that the project complies with the 401 Water Quality Certifications associated with Nationwide Permit 39. A Pre-construction Notification Application (PCN) is attached, which includes an agent authorization form. The proposed project consists of impacts from the construction of access roads and a sanitary sewer connection for a residential housing development. The site is located on the north side of Highway 98 and the south side of Freeman Rd (SR 1846). The project lies between Fletcher Chapel Road (SR 1815) and Clayton Road (SR 1825) with the southeastern property line formed by Little Lick Creek. The site is approximately 112 acres in size, and consists primarily of pine and hardwood stands. Please refer to the attached USGS map, which displays the location of the proposed project. S&EC conducted a detailed wetland delineation and Neuse River Buffer evaluation on June 5, 2003. Maps were sent to the USACE on October 21, 2003 for approval.

A copy of his letter is attached. The applicant requested a detailed wetland delineation and buffer evaluation on the property prior to site plan development in order to avoid jurisdictional features and riparian buffers to the maximum extent practicable. The proposed roadway will impact approximately 0.1895 acres of jurisdictional wetlands, 132 linear feet of perennial stream channel, and 69 linear feet of intermittent channel. These impacts are elaborated upon within the attached PCN form and are shown on the attached inset impact maps. The proposed road crossing (impact # 1) is necessary to gain access for the property from an existing road located east of the site. The road crossing will impact a segment of intermittent channel and associated buffers. Because the road must "tie into" an existing road east of the site, the proposed road crossing cannot be constructed perpendicular to the stream. Impact #2 was requested by the city of Durham to meet "interconnectivity" requirements among subdivisions. However, this impact could be avoided using a cul- de-sac. In the past, the USACE has not always agreed that interconnectivity ordinances justify the additional wetland impacts (i.e. the impact could be avoided). We are requesting this impact because the city of Durham has made it a condition for PUD approval; however, Durham has stated that if the Corps or DWQ denies the request for impacts, they will amend the PUD to allow a cul-de-sac. The sanitary sewer connection (impact # 3) will impact a portion of the riparian buffer in order to connect to an existing utility line. This impact is temporary, and is a necessary utility for the proposed development. The applicant will minimize impacts using headwalls at the proposed crossing. Following construction, the applicant will maintain riparian buffers on the stream channels as well as employ BMP devices to preserve water quality. Stormwater will be treated or released as sheet flow (i.e. diffuse) before entering the buffers. Moreover, because this site is located within a water-supply watershed, Durham regulations will not allow >24% impervious surface within the site. The USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification (0.10 acre). The proposed roads are necessary to access the entire property. Because the applicant has minimized impacts to the maximum extent practicable, will maintain riparian buffers, and will preserve approximately 9 acres of wetland, S&EC does not believe further compensatory mitigation should be required by the USACE. NC-DWQ's current policy requires written concurrence for stream impacts of greater or equal to 150 linear feet of stream length per project. We request written concurrence that the project complies with the 401 Water Quality Certification associated with Nationwide Permit 39. NC-DWQ's current policy does not require wetland or stream mitigation for perennial stream channel impacts below 1 acre and 150 linear feet per project. Because the total permanent impacts to perennial channels is less than 150 feet and a total of 0. 1895 acres of permanent impacts to wetlands are proposed, we do not believe that wetland nor stream mitigation should be required by NC-DWQ. Please note that following construction the site will contain less than 30% impervious surface. Therefore, we do not believe that this project requires a pre-approved stormwater plan. Please call if you require any additional information or have any questions.

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.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): NA Size of watershed draining to pond: NA Expected pond surface area: NA VI. 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. A detailed delineation was conducted in order to developa site plan that minimized impacts. Impact # 1 is necessary to access the area from the existing subdivision adjacent to the property. Due to the location of the existing road east of the proposed project this impact could not be avoided entirely. Impact # 2 was requested but not required by the city of Durham to meet "interconnectivity" requirements among subdivisions. However, this impact could be avoided using a cul-de-sac In the past the USACE has not always agreed that interconnectivity ordinances justify the additional wetland impacts (i.e. the impact could be avoided). We are reguestinE this impact because the city of Durham has made it a condition for PUD approval; however, Durham has stated that if the Corps or DWQ denies the request for impacts, they will amend the PUD to allow a cul-de-sac. Impact # 3 (buffer impact) is necessary to tie into the existing sanitary sewer that will service the proposed subdivision. In addition the applicant will utilize BMP devices for water treatment. VII. 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 March 9, 2000, 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 Page 5 of 8 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 NCWRP 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/ncwetiands/strmgide.liti-ni. 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. Because impacts are below the thresholds that typically require mitigation and because approximately 9 acres of wetlands will be preserved on-site we do not believe mitigation should be required. However, if mitigation is required, we propose payment to the WRP. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.ne.us/wrp/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): NA _ Amount of buffer mitigation requested (square feet): NA Amount of Riparian wetland mitigation requested (acres): NA Amount of Non-riparian wetland mitigation requested (acres): NA Amount of Coastal wetland mitigation requested (acres): NA VIII. Environmental Documentation (required by DWQ) Does the project involve an expenditure of public (federal/state) funds or the use of public (federal/state) land? Yes ? No Page 6 of 8 If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No El If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? IX. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Meuse), 15A NCAC 213 .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify__ _ )? Yes N No ? If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Zone* Impact (square feet Multiplier Required Mitigation _ 1 14,226 3 NA 2 10,552 1.5 NA Total 24,778 NA * Zone 1 extends out 30 feet perpendicular trom near oanK or cnannei; cone L cxicnu w, additional 20 feet from the edge of Zone 1. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0260. Page 7 of 8 X. Stormwater (required by DWQ) Describe impervious acreage (both 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. The site does not currently contain impervious surface Following construction the site will contain less than 30% impervious surface therefore we do not believe a pre-approved stormwater plan is required Moreover, because this site is located in a water supply watershed, Durham regulations prohibit any development that exceeds 24% impervious. The applicant will provide measures to insure that diffuse flow is achieved before stormwater enters the buffers as well as maintain a riparian buffers XI. 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. Sanitary Sewer XII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 21-1.0500) or any Buffer Rules? Yes ? No E Is this an after-the-fact permit application? Yes F-1 No® XIII. 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). /.Y.
