The dewatering pump will be an 8-in Godwin Dri-Prime model running at 1200 rpm with 8,000 gallons per hour flowing into sediment pond. Pump will operate intermittently for an average of 12 hours per day upon need. 9. Operator will excavate the remaining permitted excavation area (12.7 acres) by digging with the excavator and removing sand & topsoil to maximum depth feasible before dewatering the excavation. 10. Operator will dewater main excavation into sediment pond, discharging overflow water from sediment pond through half-pipe riser water height control through discharge pipe into woods swale leading to wetlands and blue-line stream. Operator will dewater main excavation down approximately 20 feet below normal groundwater level. 11. 3:1 cut slopes will be constructed around excavation edge down to normal groundwater level. As water is removed from excavation, 2:1 cut slopes will be constructed below normal groundwater level around excavation edge. 12. Pond will be excavated to an average of 30 feet and maximum 35 feet below natural ground level while dewatering is maintained. Excavated material(sand)will be stockpiled in an unexcavated portion of proposed excavation area or 0.25-acre processing area west of excavation. Sand will be loaded onto trucks and removed from the area via construction entrance to NC 45. 13. When final excavation of pond is complete, dewatering will be discontinued, and pump shut down and removed. Groundwater will refill the excavation to normal seasonal high groundwater level. 14. Separation berm between pond and sediment pond will be removed by excavation. ponds will be joined into one 12.7-acre pond. 15. After all excavation is complete, operator will establish groundcover on 3:1 above-water slopes of excavation and will construct 8-ft wide 4:1 berm around excavation edge to prevent erosion of pond slopes, with outside edge of berm graded down to natural ground level. 16. Former stockpile/ berm areas and processing areas outside of main excavations will be graded, leveled, and seeded with groundcover. Areas will be allowed to return to their previous non-erosive field state. 17.

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 south berm of the sedimentation pond at Lee Hoggard Sand Mine. Overflow to be directed down stabilized ditch to nearby ground-levelling ditch, eventual outflow to Chowan River and Albemarle 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 Lee Hoggard Sand Mine, NC 45, Merry Hill, NC. Sedimentation pond is a part of the dewatering management system of Lee Hoggard 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. << �C' e Ken Elliott, consulting February 2, 2024 Discharge Outfall Outlet Protection:Construction Details Practice Standards and Specifications 6.41,6.31,6.15 Lee Hoggard Sand Mine Merry Hill,NC Berne County 6.41 Outlet Stabilization Structure 6.31 Riprap and Paved Channels 6.15 Riprap Pipe Outlet to Well-defined Channel A JA La s -- f'Al-1_ za'" i�il i,I�,.

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. Ken Elliott,consulting February 2, 2024 Berm Construction Details Lee Hoggard Mine Merry Hill,INC Berne 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. 10, r J 2 J 1 NEW BERM EXISTING GRADE Berm Construction The berm construction comprises of the scraping back of the topsoil from the area where the berm and storage basin are 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 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. Ken Elliott,consulting February 2, 2024 Sediment Fence (Silt Fence) Construction Details: Practice Standards and Specifications 6.62 Lee Haggard Sand Mine Merry Hill, NC Bertie County _L A temporary permeable barrier erected on small,disturbed areas to capture sediment from sheet flow. 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 12-ft wide access road when crossing an existing field ditch. 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 "I" 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.
