Please take notice that this certificate of coverage is not transferable except upon approval of the Division of Energy, Mineral and Land Resources (DEMLR). DEMLR may require modification or revocation and reissuance of the certificate of coverage. This general permit allows the discharge of stormwater and certain types of wastewater from your facility. in your application, you specified that only mine dewatering water would be discharged from this facility. If separate point -source discharges of stormwater occur (i.e., stormwater not combined with mine dewatering water), you must adhere to the conditions in this permit for stormwater discharges. Please be aware that mine dewatering at your site has the potential to impact adjacent wetlands. The specific requirements for mine dewatering at facilities near wetlands can be found in Part III, Section E of your permit. You must have an approved Operation and Monitoring Plan before mine dewatering discharges occur at your facility. Discharging mine dewatering wastewater without Plan approval will be subject to enforcement action. An Operation and Monitoring Plan for your facility must be submitted to the Washington Regional Office within 60 days of your receipt of this permit.

Bayview Road, Powells Point, NC 27966 County: Currituck County Prepared by: Ken Elliott, consulting Date: December 4, 2017 This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures used for constructing and dewatering the Bayview Sand Mine safely, and that dewatering will not degrade or negatively impact any wetlands or waters of the state. Description and Operation of the Bayview Sand Mine: The Bayview Sand Mine is a proposed 5.04-acre sand mine excavation operated by HOM Development, LLC, Jamie Basnight Hatchell, operator, in a 22.63-acre permit area located off S. Bayview Road, Powells Point, NC, in Currituck County. The permit area is on high sandy land and is currently a cultivated farm field owned by Atlantic OBX, Inc, At this time HOM Development is applying for a mining permit with the NCDEQ Division of Energy, Mineral and Land Resources to construct the sand mine and begin operation in January 2018. HOM Development is also applying for a Use Permit from the Currituck County Planning Department for construction of this mine. Sand Mine Dewatering: It will be necessary to dewater the excavation as it is being excavated to allow the excavating equipment to enter the excavated area and safely and efficiently remove the sand from the pond bottom. This will allow for full depth excavation and proper reclamation of the edges of the pond. It is the intention of HOM Development to only dewater the excavations as needed, which will not entail full-time dewatering. For excavation purposes, dewatering will occur roughly every 30 days which will allow excavating equipment to remove approximately 150 loads of sand up to ground level where it will be stockpiled for later use. When the stockpile is depleted from usage, the excavation area will again be dewatered, and another quantity of sand will be excavated. The operator plans to construct a 0.50-acre above -ground sedimentation pond located 30 feet north main excavation area. The 6-ft tall berm around the pond will have exterior 3:1 slopes with full groundcover installed, and interior 2:1 slopes. Excavation of the main 5.04-acre pond will begin approximately 30 feet from the sediment pond. The edge of the sediment pond excavation and main excavation will be 75 feet from the nearest wetland swamp. Use of the sediment pond will forcibly hydrate the nearby wetlands located west of the sediment pond and excavation, and will minimize dehydration of the swampy land. The operator will install an 8-inch dewatering pump between the 2 ponds at the north end of the main excavation. Discharge from the dewatering pump will enter the sediment pond on its northeast end, and there will be a constructed water height control device (see attached diagram) discharge point located on the west end of the sediment pond. The discharge point will release clear water to a 25-foot- long riprap-protected ditch, leading 25 feet to an existing field irrigation and drainage ditch (non -blue - line stream), then 0.25 miles by ditch to the Betsy's Creek wetlands and swamp, then 0.3 mile to Currituck Sound. Water will be pumped from the main pond to the sediment pond by the 8in gasoline -powered transfer pump operating at idle speed. Estimated maximum flow from the pump will be 2,000 gallons/hour, operating 12 hours per day, 0.024 mgd. it is the intention of the operator to drop the water level in the main pond approximately 20 - 25 feet below normal ground level when needed. The overflow from the sediment pond will be controlled by a water height control device constructed in the northeast corner of the sediment pond. This control structure will allow water to flow through the baffle into a 25ft long x 15" wide buried PVC pipe leading northeast 25 feet to a Eft wide drainage ditch running north and east through a field drainage ditch, then to Currituck Sound. For erosion control, the overflow water will exit the water height control discharge pipe onto a 20ft long riprap-lined apron in the ditch. Time and distance will allow all sedimentation to occur to acceptable levels before the overflow water reaches outfall and then the waters of the State. Water will have to travel a minimum of 270 feet to reach the overflow point which will give enough surface area to allow sufficient sedimentation to occur. There will be a minimum 1.5 feet of freeboard between the water surface in the sediment pond and the top of the sediment pond bank. Stormwater drainage will be unable to enter the sediment area and damage the sediment pond rates, due to the height of the surrounding sediment pond berm. Sedimentation and Erosion Control There is wetland swamp north and east of the proposed excavation, located 75 feet from the excavation edge, running parallel to the north and east permit area boundary. The operator will establish a 50-ft wide undisturbed buffer (no disturbance of any kind) as a visual screen of existing woodland which is part of the Currituck County required property line setback. This buffer will be adjacent to, and inside of, the permit boundary. This buffer will be maintained by the operator as grass and pine tree ground cover. In addition, there will be a 25ft unexcavated buffer (may contain roadways, stockpiles, and sediment & erosion control devices) around the entire excavation area, between the excavation and the undisturbed buffer. Sediment pond overflow will drain into an operator -maintained Eft wide feeder ditch that leads 25 feet to a field irrigation and drainage ditch, then 0.25 miles to the Pasquotank River. Overflow into the feeder ditch will be stabilized by riprap installed in the feeder ditch at the overflow (see diagram) to prevent erosion of the ditch. All erosion and sedimentation will remain inside of the permit area. The operator will construct and maintain an 10ft wide x 2ft tall grass -covered sand berm around the perimeter of the current affected area of the excavation during all phases of operation. During mining operations and dewatering, most of the water leaving the excavation will remain inside of the permit area and will only overflow through the sediment pond occasionally. The sediment pond will be approximately 5 feet deep, and there is a sand layer below the bottom of the area. The porosity of the soil under the sediment pond will allow most of the water pumped into the pond from dewatering to seep back into the ground naturally. Any excess water overflowing from the sediment pond will flow downstream 0.5 miles to Betsy's Creek and Currituck Sound. Maintaining the Sediment Pond Overflow Control Structure, Settlement Pond and Ditches Inspections and maintenance are required to obtain the intended function of safely dewatering the sand mine, and to maintain the life of any adjacent wetlands or waters of the State. Items to inspect and maintain during the anticipated 10-year life of the mine dewatering permit are: • Inspect the water control structures regularly, especially following heavy rains and runoff, or during periods of operation of the structure. • Remove accumulated debris from the overflow control structure, • Inspect the structure for excessive settlement or seepage. • Inspect all components of the structure, including appurtenances, and repair or replace any damaged items as needed. • Inspect embankments, berms and appurtenant structures, and repair as needed. • Repair any damage to vegetated areas or berms with compacted earth fill, reshaping, sodding, reseeding and mulching as needed. • Inspect riprap outlet stabilization structures in ditches regularly, replace dislodged rock as necessary. • Promptly repair all leaks in delivery facilities by replacing valves, fittings, gaskets, and worn or damaged parts. • Maintain all screens, filters, valves, timers and other electrical and mechanical equipment in good operating condition, following manufacturer's recommendations Monitoring the Process and Effects of Dewatering Analytical and qualitative monitoring of mine dewatering wastewater will be in accordance with the NCG020000 permit, as follows: • All ponds in the Bayview Sand Mine permit area will be inspected daily by the operator to identify any abnormal conditions. • All berms and erosion control and sedimentation control structures will be inspected for damages monthly and within 24 hours after every storm event greater than 1.5 inches, and all structures will be repaired immediately. • Special inspections will be conducted immediately following severe storms, vandalism, and other significant events. • Dewatering process will be inspected daily during periods of dewatering the excavation. • Overflow of wastewater process will be inspected daily during periods of dewatering the excavation. • Outflow of dewatering wastewater will be monitored quarterly at the.overflow exit stabilization structure for pH, settleable solids, turbidity, and total flow. Samples will be collected and tested onsite for pH, and the remainder will be tested for the remaining parameters by a North Carolina certified lab. • Rain gauge data will be collected by monitoring rain gauge data monthly and after each rain event. Records Data will be collected as follows: • Data will be collected from samples taken from the'wastewater point source discharge in operation at the time. • Point source discharge data: data from the site taken quarterly, date & time, general weather conditions, pH of sample, status of process at point source, inlet or outlet, other DWQ required data. • Visual monitoring of adjacent wetlands and farmland for potential dehydration during mining or dewatering activities will take place weekly. Solutions to any degradation caused by any mining activity will include alteration of dewatering process. DWQ will be consulted as needed; alterations to process will be recorded. • Elliott Consulting will maintain the following records in a permanent file at the Elliott Consulting office at PO Box 112, 202 Elliott Road, Aydlett, NC 27916: a record of all significant actions taken; as -built drawings; permits; analytical results from sampling; and related material. Copies of all inspections, monitoring reports and lab analyses shall be provided to NCDWQ on a regular basis and as requested. BMP Conditions • The permittee will utilize best management practices to ensure that dewatering the Bayview Sand Mine will not degrade or negatively impact any wetlands or waters of the State. BMP's will include: o Sediment pond outlet structure with flashboard riser located at edge of pond for ease of maintenance o All berms and erosion control and sedimentation control structures will be inspected for damages monthly and within 24 hours after every storm event greater than 1.5 inches, and all structures will be repaired immediately. o Sediment pond outlet ditch will have rock lining or riprap stone layer to prevent erosion, scour or sloughing of embankment • The permittee shall obtain authorization from the Director of the NCDEMLR and the Stormwater Program chief prior to utilizing any chemical flocculants at Robert White Sand Mine.

Riprap Apron Size: Overflow pipe discharges directly into well-defined channel. The apron will extend across the channel bottom and up the channel banks to the top of the bank. Length of apron will be 20- feet downstream to maintain velocity control of maximum 2.0 feet per second. Grade: Apron will have zero grade and no overfill at end of apron. Alignment: Apron will be straight throughout entire length if possible. If curve is necessary to align the apron with the receiving channel, the curve will be located in the upstream section of the riprap. Materials: Riprap will consist of a well graded mixture of NCDOT Class A (2" to 6") stone or slag. Thickness: Minimum thickness of riprap will be 1.5 times the maximum stone diameter. Filter: Operator plans to install a layer of heavy duty silt fence filter cloth between the riprap and the underlying soil to prevent soil movement into or through the riprap. Filter cloth will extend to the top of both channel banks, and edges will overlap 12 inches. Upstream end will be buried 12 inches and downstream end will be buried if necessary. Maintenance: inspect riprap outlet structures weekly and after significant rainfall events to see if any erosion around or below the riprap has taken place, or if stones have become dislodged. Repair all damage immediately. Maintain all vegetation adjacent to the channel in healthy condition to prevent scour or erosion during out -of -bank flow. Control weeds and brush growing in the riprap by cutting.

Water height control structure is standard structure used by agricultural and horticultural farms in North Carolina to raise or lower water height in ditches and ponds per need (NRCS). Water height control structure to be installed in the north berm of the sedimentation pond at the Beyview Sand Mine. Overflow to be directed down stabilized ditch to nearby Betsy's Creek, eventual outflow to Currituck Sound. PURPOSE To convey water from one elevation to a lower elevation within, to, or from a water conveyance system, such as a ditch, channel, canal, or pipeline designed to operate under open channel conditions. Typical structures: drops, chutes, turnouts, surface water inlets, head gates, pump boxes, and stilling basins (NRCS). This water management system will be used to maintain a maximum water surface elevation in the sedimentation pond at the Bayview Sand Mine. Sedimentation pond is a part of the dewatering management system of the Bayview Sand Mine, used to remove settleable matter and turbidity from mine dewatering wastewater. CONSTRUCTION Structure consists of 26' x 3' horizontal galvanized steel culvert running under the sedimentation pond berm. A vertical 6' half pipe 52" x 30" is attached on the north end of the culvert with stacked flash boards allowing adjustable height of the water level in the sedimentation pond. Water flows over the flash boards and into the discharge pipe and down the rip -rap stabilized ditch. Overflow ditch is lined with riprap for 20 feet down its length. Existing slopes adjacent to the culvert are heavily grassed with natural grass and weeds with no erosion present. MAINTENANCE Structures will be checked and necessary maintenance, including removal of debris, shall be performed after major storms and at least semi-annually. Ken Elliott, consulting December 3 Berm Construction Details Bayview Sand Mine Powells Point, INC Currituck County Narrow -based berm The narrow -based berm is the most common berm having a top of 2 feet (0.6 m) and side slopes of two horizontal: 1 vertical. This berm is the most economical to build as it requires the least material. The steep side slopes of this type of berm eliminate the possibility of working on it with farm machinery. 3 • i 4' 2` 2. f NEW BERM Exf5T(NG5 GRADE Berm Construction The berm construction comprises of the scraping back of the topsoil from the area where the berm and storage basin is to be built. A subsoil material, free of stones, rubble, stumps etc. and with at least 10% clay should be used to construct the berm. The material for the berm may be obtained from the area behind or in front of the berm location or moved from a borrow pit located elsewhere on the farm. An earth mover will be required to move material from a pit located a distance away while a bulldozer would be used if material is located in the berm area. The berm material is to be placed in layers and compacted as each layer is added. After the berm has a final shape the sides of the berm should also be compacted. Emergency Overflow To provide for larger -than designed peak flows, an overflow system is used, namely: "The level -top vegetated berm crest" which provides for very flat berm top so that the water will overflow along the berm length in a thin layer so as not to create erosion problems.

It is made of filter fabric buried at the bottom, stretched and supported by steel posts. Planning: Silt fence will be installed along the perimeter of a 15ft wide access road when crossing a blue -line stream. Crossing is existing with 24-in cement culvert. Narrow width of fenced area will allow only shallow pools to form behind fence while promoting deposition of sediment and preventing sedimentation into adjacent wetlands. Ends of fence will be curled uphill in "J" pattern to prevent end flow. Stabilized outlets will be provided to protect the fence system and release storm flow that exceeds the design. Design considerations: Silt fence will be constructed of extra -strength synthetic filter fabric. Height of fence will not exceed 2 feet above natural ground level, and will be constructed from a continuous roll to minimize joints. All joints will be fastened at a support post with 4 feet minimum of overlap. Extra -strength filter fabric will be fastened to road side of steel posts (installed 2 feet deep) every 6 feet (every 8 feet if using standard strength filter fabric with wire mesh backing) and fastened with wire ties. Trench will be excavated along inside of fence approximately 4 inches wide by 8 inches deep, into which 12 inches of fabric will be placed along the bottom and side of the trench. Trench will be backfilled and compacted. Maintenance: Inspect sediment fence every week and after each rainfall. Make any required repairs immediately. Replace any collapsed, damaged, or decomposed fence promptly. Remove all fencing materials and unstable sediment deposits and bring the area to grade and stabilize it after the contributing drainage area has been properly stabilized.
