APPLICANT'S CERTIFICATION I, (print or hrye name of person listed in General Information, item 2) Charles Sechrist certify that the information included on this permit application form is, to the best of my knowledge, correct and that the project will be constructed in conformance with the approved plans, that the required deed restrictions and protective covenants will be recorded, and that the proposed project complies with the requirements of 15A NCAC 2H .1000. Date: 1" Form SWU-101 Version 09.25.08 Page 4 of STORMWATER MANAGEMENT PERMIT APPLICATION NARRATIVE SUPPLEMENT TO ITEM III-1 The proposed Wendy's - Edenton site is located on the northeast side of NC Hwy 32, approximately 0.25 miles northwest of the intersection with NC Hwy 17 in Edenton, NC. The project site has one BMP in place to help treat stormwater quantity. The BMP utilized is a stormwater wetland and it shall be owned and maintained by the Sechrist Management Group, LLC, the owner and operator of this Wendy's Restaurant.. The majority of the stormwater runoff currently drains to the south corner of the property via existing ditches surrounding the site. The remaining stormwater runoff drains to the west comer of the property into existing drainage pipes. The 1.62-acre parcel is currently abandoned with approximately 0.28 acres of impervious surface remnants still on -site. Upon development, these will be demolished and approximately 0.90 acres of impervious surface will be added to the site. This will increase the stormwater runoff rate as it is creates a total increase in impervious area of roughly 0.62 acres. This runoff will be routed to the proposed stormwater wetland for stormwater attenuation and treatment. The proposed stormwater wetland has been designed and will be constructed to provide water quantity and quality benefits to downstream waters. This wetland has been sized and configured to maintain a permanent pool of water designed to sustain wetland plant growth for a targeted TSS removal. This permanent pool elevation has, also, been set at an elevation that will allow the wetland to store the peak runoff from the site up to and including the 100-year storm event. The wetland will release this volume of water over a period of time so as to not inundate downstream drainageways. The stormwater wetland will consist of a sediment forebay, planting areas (upland, shallow land & shallow water), and deep pool. The sediment forebay is approximately 3-foot deep. The shallow marsh areas are only 3 — 6 inches deep with the shallow water areas up to 12 inches deep. The uplands extend to roughly 3 feet above the permanent POOL and the deep pools are between 1.5 — 3-foot deep with the deepest point being the micropool at the outlet structure. The pre -development 1-year, 24-hour peak flow (1.5-inch rainfall depth) for Drainage Area 1 is 0.16 cfs. This drainage area takes in runoff from the entire development as shown on the BMP Map. Flow is released from the pond into roadside ditches via an 15-inch RCP. Using this stormwater wetland, the post -development 1-year, 24-hour peak flow runoff rate for Drainage Area 1 is reduced to 0.035 cfs. ®�� NCDENR North Carolina Department of Environment and Natural Resources Beverly Eaves Perdue Governor Mr. Charles Sechrist, Registered Agent Sechrist Management Group, LLC 3670 Virginia Avenue Collinsville, VA 24078 Dear Mr. Sechrist: Division of Water Quality Coleen H. Sullins Director November 18, 2009 Subject: Stormwater Review SW7090603 Wendy's - Edenton Chowan County Dee Freeman Secretary This office received a Coastal Stormwater permit application and plans for the subject project on June 10, 2009, with additional information received on October 12, 2009. A preliminary review of the project indicates that before a State Stormwater permit can be issued the following additional information is needed. 1. The application does not include your title within Sechrist Mangement Group, LLC. The previous operation and maintenance agreement lists you as the registered agent. The president, vice-president or managing member of the corporation must be the signing official on all the forms. Please verify your title. 2. Neither the application form nor the Wetland Supplement form were initialed, signed and notarized. Please provide the original signed forms for both. 3.

Please provide an outlet structure detail for the constructed wetland, including elevations, orifice size, trash guards, etc.. 6. Please include a time line for the project contractor in which he is to plant the wetland plants for optimum survivability. It is also a good idea to include in your contract and plans a replanting plan specifying that if a certain amount of plants do not survive the first growing season then that amount will be replanted for the next growing season. 7. Please do not forget to have any plans, calculations, supplements, narrative, etc. revised, signed, sealed and dated as necessary when re -submitting. The above requested information must be received in this office prior to December 18, 2009 or your application will be returned as incomplete. The return of this project will necessitate resubmittal of all required items including the application fee. If you need additional time to submit the required information, please mail or fax your request for time extension to this office at the Letterhead address. You should also be aware that the Stormwater Rules require that the permit be issued prior to any development activity. Construction without a permit is a violation of 15A NCAC 2H.1000 and North Carolina General Statute 143- 215.1 and may result in civil penalties of up to $10,000 per day.

I was authorized by you to perform a soil evaluation of the native soils on the site. Specifically, you wanted to know the depth to the `seasonal high water table' and soil permeability for an infiltration system to control stormwater at the site {I 5A NCAC 02H .1008 (d)). My work consisted of hand auger borings into the surface soils to observe and describe physical properties such as texture, color, structure, consistency, depth to seasonal groundwater, parent material, and restrictive horizons. The work was performed on March 24, 2009. The soil at the site consists of 12 to 16 inches of sandy textured topsoil that has been disturbed in the past. Below this topsoil is a firm to very firm, sticky, plastic, yellowish brown and gray mottled sandy clay that has weak, medium, blocky structure. This layer extends to a depth of about 40 inches. Below this subsoil layer is sandy clay loam. The groundwater table was encountered at a depth of 35 inches beneath the surface as free water in the borings. Depth to seasonal water table is observed by soil colors present (Chroma 2 or less), landscape position, soil structure, and soil layers that may `perch' or restrict downward water movement. Low chroma colors are formed when soil is saturated for at least 21 days and then moves downward. As the soil water moved downward it takes the more soluble oxides of iron and aluminum that coated the soil and leaves the depleted gray colors. The approximate locations of the borings are shown on the attached drawing. The table below presents the actual seasonal high water table depths observed in the hand auger borings. Boring 1 12 13 14 SHWT Depth inches 12 14 15 15 The soil permeability of the sandy clay textured subsoil was not measured. Based on the texture, structure and consistence of this layer, I estimate that the permeability of this layer will be less than 0.52 inches per hour. Based on the estimated permeability, depth to seasonal high water table, and depth to groundwater, this site is not suitable for an infiltrative stormwater type system. Fred D.

I am requesting this due to a number of extenuating circumstances, which are: (1) the developer has requested a decrease in the amount of impervious area and fill due to development costs, which required a substantial re -design for us; (2) the soil scientist required time to re-evaluate a particular portion of the property for an alternative BMP design; and, (3) the NCDOT was delayed in forwarding updated contour information to our office so that we might verify downstream ditch and pipe invert elevations (changes have been made by NCDOT along NC 32 since our original site survey was completed). I do apologize for the continued delay, but our re -design and suporting calculations will be ready to submit by this coming Wednesday. A deadline extension of Thursday, October 8` , would be gracious.on your part and greatly appreciated on ours. Thank you for considering this request. Please contact me with any questions or requests for further documentation. Sincerely, Stocks Engineering, P.A.

This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important maintenance procedures: — The drainage area will be carefully managed to reduce the sediment load to the sand filter. — Once a year, sand media will be skimmed. — The sand filter media will be replaced whenever it fails to function properly after vacuuming. The sand filter will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows.
