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.

RR r emergenc-y spillway 4 ,.r.� bR �,�.�r � .• sa � 1- .i riser water detention level :r1prap embankment grass rip rap barrel sediment forebay concrete base DESCRIPTION A structure in a water management system that conveys water, controls the direction or rate of flow, maintains a desired water surface elevation or measures water. 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 the Buddy Smith Mine. Overflow to be directed down stabilized ditch to nearby blue-line stream, eventual ouMow to Scuppernong River. 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 Buddy Smith Mine, Travis Road, Columbia, NC. Sedimentation pond is a part of the dewatering management system of the Buddy Smith 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. << ��-Q F Ken Elliott, consulting October 4, 2022 Discharge Outfall Outlet Protection: Construction Details Practice Standards and Specifications 6.41,6.31,6.15 Buddy Smith Mine Columbia,NC Tyrrell County 6.41 Outlet Stabilization Structure 6.31 Riprap and Paved Channels US Riprap Pipe Outlet to Well-defined Channel A J La _..__ 1 li! �d (Ill -11 — :i ;I ,!�= Section AA + .. w Filter blanket Trapezoidal Riprap Channel Design top width �i 1�; I Design depth �;1! ;i i.WY L Filter layer,gravel or fabric Riprap lined apron located at end of mine dewatering overflow pipe to prevent scour and undermining in discharge ditch,and to absorb the impact of the water flow and reduce the velocity to non-erosive levels, before flow reaches wetlands. 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 October 4, 2022 Sediment Fence (Silt Fence) Construction Details: Practice Standards and Specifications 6.62 Buddy Smith Mine Columbia, NC Tyrrell County 1C >4F" l _z A temporary permeable barrier erected on small disturbed areas to capture sediment from sheet flow. It is made of filter fabric burled at the bottom, stretched and supported by steel posts. Planning:Silt fence will be installed along the perimeter of a 25ft 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 "1" 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.
