Corprew, River Farms, LLC, 910 Wynne Fork Road, Hertford, NC 27944 Job Location: River Farms Mine, Harvey Point Road, Hertford, NC 27944 County: Perquimans County Prepared by: Ken Elliott, consulting Date: June 22, 2016 This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures used for constructing and dewatering the River farms Mine safely, and that dewatering will not degrade or negatively impact any wetlands or waters of the state. Description and Operation of the River Farms Mine: The River Farms Mine is a proposed 35.6-acre sand mine excavation operated by River Farms, LLC, Timothy J. Corprew, owner, in an 83.66-acre permit area located on Harvey Point Road. The site is approximately .50 miles south of Hertford, NC, in the Town of Hertford Extraterritorial Jurisdiction area. The permit area is on high sandy land, recently cleared, and currently under cultivation as a turf grass farm. At this time Mr. Corprew is submitting an application with the NCDEQ Division of Energy, Mineral and Land Resources to construct the sand mine and begin operation in July 2016. Mr. Corprew is also submitting an application for a Special Use Permit from the Town of Hertford 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 in order to 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 Mr. Corprew 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 initially excavate two 1.82-acre ponds on the north and south sides of the excavation area, both being located inside the main excavation area. Initially used as water sources for the turf farm, the ponds will be later used as sedimentation ponds during the main pond excavation. The ponds will be constructed with 3:1 slopes above normal groundwater height with full groundcover installed, and 2:1 slopes below normal groundwater level. Once the small ponds are completed the rest of the 35.6-acre main excavation will begin between the sediment ponds and the east end of the excavation area. The edge of the sediment pond excavations and main excavation will be a minimum of 100 feet from the nearest wetlands. Use of the sediment ponds will forcibly hydrate the nearby wetlands located north and south of the sediment ponds and excavation, and will minimize dehydration of the swampy land. The operator will install an 8-inch dewatering pump between the main excavation and the closest sediment pond. Discharge from the dewatering pump will enter the sediment pond on its east 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, which then leads 75 feet to wetlands, then 1200 feet through wetlands to the Perquimans River. Water will be pumped from the main pond to the sediment pond by the Bin gasoline -powered transfer pump operating at idle speed. Operator will utilize one or both sediment ponds and pumps as needed. Estimated maximum flow from each pump will be 8300 gallons/hour, 0.20 mgd (4150 gallons / hour / pump). It is the intention of Mr. Corprew 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 west bank of the sediment pond in use. This control structure will allow water to flow through the baffle into a 2Sft long x 15" wide buried PVC pipe leading 25 feet to a 6ft wide drainage ditch running north or south 75 feet to wetlands and then 1200 feet to the Perquimans River. 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 in the sediment ponds before the overflow water reaches outfall and then the waters of the State. Water will have to travel a minimum of 400 feet in the sediment pond to reach the overflow point, which will give enough surface area to allow sufficient sedimentation to occur. There will be a minimum 2 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 due to the height of the sediment pond berm and damaging sediment pond rates. Sedimentation and Erosion Control There is wetland swamp on the north and south side of the proposed excavation, located 100 feet from the excavation edge, running parallel to the affected area boundary. The operator will establish a 50ft undisturbed buffer (no disturbance of any kind) between the southwest boundary of the affected area and the adjacent wetland area. This buffer will be maintained by the operator as pasture with grass and pine tree ground cover. In addition, there will be a 50ft 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 a constructed 6ft wide drainage ditch that leads 25 feet to a field irrigation and drainage ditch, then 75 feet to wetlands and then 1200 to the Perquimans River. Overflow into the outfall ditch will be stabilized by riprap installed in the 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 8ft 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, the majority 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 10 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 1200 feet to wetlands leading to Perquimans River. 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 River Farms 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 River Farms 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.

Corprew, River Farms, LLC, 910 Wynne Fork Road, Hertford, NC 27944 Job Location: River Farms Mine, Harvey Point Road, Hertford, NC 27944 County: Perquimans County Prepared by: Ken Elliott, consulting Date: June 22, 2016 This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures used for constructing and dewatering the River farms Mine safely, and that dewatering will not degrade or negatively impact any wetlands or waters of the state. Description and Operation of the River Farms Mine: The River Farms Mine is a proposed 35.6-acre sand mine excavation operated by River Farms, LLC, Timothy J. Corprew, owner, in an 83.66-acre permit area located on Harvey Point Road. The site is approximately .50 miles south of Hertford, NC, in the Town of Hertford Extraterritorial Jurisdiction area. The permit area is on high sandy land, recently cleared, and currently under cultivation as a turf grass farm. At this time Mr. Corprew is submitting an application with the NCDEQ Division of Energy, Mineral and Land Resources to construct the sand mine and begin operation in July 2016. Mr. Corprew is also submitting an application for a Special Use Permit from the Town of Hertford 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 in order to 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 Mr. Corprew 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 initially excavate two 1.82-acre ponds on the north and south sides of the excavation area, both being located inside the main excavation area. Initially used as water sources for the turf farm, the ponds will be later used as sedimentation ponds during the main pond excavation. The ponds will be constructed with 3:1 slopes above normal groundwater height with full groundcover installed, and 2:1 slopes below normal groundwater level. Once the small ponds are completed the rest of the 35.6-acre main excavation will begin between the sediment ponds and the east end of the excavation area. The edge of the sediment pond excavations and main excavation will be a minimum of 100 feet from the nearest wetlands. Use of the sediment ponds will forcibly hydrate the nearby wetlands located north and south of the sediment ponds and excavation, and will minimize dehydration of the swampy land. The operator will install an 8-inch dewatering pump between the main excavation and the closest sediment pond. Discharge from the dewatering pump will enter the sediment pond on its east 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, which then leads 75 feet to wetlands, then 1200 feet through wetlands to the Perquimans River. Water will be pumped from the main pond to the sediment pond by the 8in gasoline -powered transfer pump operating at idle speed. Operator will utilize one or both sediment ponds and pumps as needed. Estimated maximum flow from each pump will be 8300 gallons/hour, 0.20 mgd (4150 gallons / hour / pump). It is the intention of Mr. Corprew 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 west bank of the sediment pond in use. This control structure will allow water to flow through the baffle into a 25ft long x 15" wide buried PVC pipe leading 25 feet to a 6ft wide drainage ditch running north or south 75 feet to wetlands and then 1200 feet to the Perquimans River. 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 in the sediment ponds before the overflow water reaches outfall and then the waters of the State. Water will have to travel a minimum of 400 feet in the sediment pond to reach the overflow point, which will give enough surface area to allow sufficient sedimentation to occur. There will be a minimum 2 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 due to the height of the sediment pond berm and damaging sediment pond rates. Sedimentation and Erosion Control There is wetland swamp on the north and south side of the proposed excavation, located 100 feet from the excavation edge, running parallel to the affected area boundary. The operator will establish a 50ft undisturbed buffer (no disturbance of any kind) between the southwest boundary of the affected area and the adjacent wetland area. This buffer will be maintained by the operator as pasture with grass and pine tree ground cover. In addition, there will be a 50ft 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 a constructed 6ft wide drainage ditch that leads 25 feet to a field irrigation and drainage ditch, then 75 feet to wetlands and then 1200 to the Perquimans River. Overflow into the outfall ditch will be stabilized by riprap installed in the 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 8ft 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, the majority 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 10 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 1200 feet to wetlands leading to Perquimans River. 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.

Corprew, River Farms, LLC, 910 Wynne Fork Road, Hertford, INC 27944 Job Location: River Farms Mine, Harvey Point Road, Hertford, NC 27944 County: Perquimans County Prepared by: Ken Elliott, consulting Date: June 22, 2016 This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures used for constructing and dewatering the River farms Mine safely, and that dewatering will not degrade or negatively impact any wetlands or waters of the state. Description and Operation of the River Farms Mine: The River Farms Mine is a proposed 35.6-acre sand mine excavation operated by River Farms, LLC, Timothy J. Corprew, owner, in an 83.66-acre permit area located on Harvey Point Road. The site is approximately .50 miles south of Hertford, NC, in the Town of Hertford Extraterritorial Jurisdiction area. The permit area is on high sandy land, recently cleared, and currently under cultivation as a turf grass farm. At this time Mr. Corprew is submitting an application with the NCDEQ Division of Energy, Mineral and Land Resources to construct the sand mine and begin operation in July 2016. Mr. Corprew is also submitting an application for a Special Use Permit from the Town of Hertford 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 in order to 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 Mr. Corprew 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 initially excavate two 1.82-acre ponds on the north and south sides of the excavation area, both being located inside the main excavation area. Initially used as water sources for the turf farm, the ponds will be later used as sedimentation ponds during the main pond excavation. The ponds will be constructed with 3:1 slopes above normal groundwater height with full groundcover installed, and 2:1 slopes below normal groundwater level. Once the small ponds are completed the rest of the 35.6-acre main excavation will begin between the sediment ponds and the east end of the excavation area. The edge of the sediment pond excavations and main excavation will be a minimum of 100 feet from the nearest wetlands. Use of the sediment ponds will forcibly hydrate the nearby wetlands located north and south of the sediment ponds and excavation, and will minimize dehydration of the swampy land. The operator will install an 8-inch dewatering pump between the main excavation and the closest sediment pond. Discharge from the dewatering pump will enter the sediment pond on its east 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, which then leads 75 feet to wetlands, then 1200 feet through wetlands to the Perquimans River. Water will be pumped from the main pond to the sediment pond by the Bin gasoline -powered transfer pump operating at idle speed. Operator will utilize one or both sediment ponds and pumps as needed. Estimated maximum flow from each pump will be 8300 gallons/hour, 0.20 mgd (4150 gallons / hour / pump). It is the intention of Mr. Corprew 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 west bank of the sediment pond in use. This control structure will allow water to flow through the baffle into a 25ft long x 15" wide buried PVC pipe leading 25 feet to a 6ft wide drainage ditch running north or south 75 feet to wetlands and then 1200 feet to the Perquimans River. 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 in the sediment ponds before the overflow water reaches outfall and then the waters of the State. Water will have to travel a minimum of 400 feet in the sediment pond to reach the overflow point, which will give enough surface area to allow sufficient sedimentation to occur. There will be a minimum 2 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 due to the height of the sediment pond berm and damaging sediment pond rates. Sedimentation and Erosion Control There is wetland swamp on the north and south side of the proposed excavation, located 100 feet from the excavation edge, running parallel to the affected area boundary. The operator will establish a 50ft undisturbed buffer (no disturbance of any kind) between the southwest boundary of the affected area and the adjacent wetland area. This buffer will be maintained by the operator as pasture with grass and pine tree ground cover. In addition, there will be a 50ft 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 a constructed 6ft wide drainage ditch that leads 25 feet to a field irrigation and drainage ditch, then 75 feet to wetlands and then 1200 to the Perquimans River. Overflow into the outfall ditch will be stabilized by riprap installed in the 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 8ft 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, the majority 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 10 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 1200 feet to wetlands leading to Perquimans River. 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: Y 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 River Farms 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.

Corprew, River Farms, LLC, 910 Wynne Fork Road, Hertford, NC 27944 Job Location: River Farms Mine, Harvey Point Road, Hertford, NC 27944 County: Perquimans County Prepared by: Ken Elliott, consulting Date: June 22,2016 This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures used for constructing and dewatering the River farms Mine safely, and that dewatering will not degrade or negatively impact any wetlands or waters of the state. Description and Operation of the River Farms Mine: The River Farms Mine is a proposed 35.6-acre sand mine excavation operated by River Farms, LLC, Timothy). Corprew, owner, in an 83.66-acre permit area located on Harvey Point Road. The site is approximately .50 miles south of Hertford, NC, in the Town of Hertford Extraterritorial Jurisdiction area. The permit area is on high sandy land, recently cleared, and currently under cultivation as a turf grass farm. At this time Mr. Corprew is submitting an application with the NCDEQ Division of Energy, Mineral and Land Resources to construct the sand mine and begin operation in July 2016. Mr. Corprew is also submitting an application for a Special Use Permit from the Town of Hertford 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 in order to 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 Mr. Corprew 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 initially excavate two 1.82-acre ponds on the north and south sides of the excavation area, both being located inside the main excavation area. Initially used as water sources for the turf farm, the ponds will be later used as sedimentation ponds during the main pond excavation. The ponds will be constructed with 3:1 slopes above normal groundwater height with full groundcover installed, and 2:1 slopes below normal groundwater level. Once the small ponds are completed the rest of the 35.6-acre main excavation will begin between the sediment ponds and the east end of the excavation area. The edge of the sediment pond excavations and main excavation will be a minimum of 100 feet from the nearest wetlands. Use of the sediment ponds will forcibly hydrate the nearby wetlands located north and south of the sediment ponds and excavation, and will minimize dehydration of the swampy land. The operator will install an 8-inch dewatering pump between the main excavation and the closest sediment pond. Discharge from the dewatering pump will enter the sediment pond on its east 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, which then leads 75 feet to wetlands, then 1200 feet through wetlands to the Perquimans River. Water will be pumped from the main pond to the sediment pond by the 8in gasoline -powered transfer pump operating at idle speed. Operator will utilize one or both sediment ponds and pumps as needed. Estimated maximum flow from each pump will be 8300 gallons/hour, 0.20 mgd (4150 gallons / hour / pump). It is the intention of Mr. Corprew 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 west bank of the sediment pond in use. This control structure will allow water to flow through the baffle into a 25ft long x 15" wide buried PVC pipe leading 25 feet to a 6ft wide drainage ditch running north or south 75 feet to wetlands and then 1200 feet to the Perquimans River. 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 in the sediment ponds before the overflow water reaches outfall and then the waters of the State. Water will have to travel a minimum of 400 feet in the sediment pond to reach the overflow point, which will give enough surface area to allow sufficient sedimentation to occur. There will be a minimum 2 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 due to the height of the sediment pond berm and damaging sediment pond rates. Sedimentation and Erosion Control There is wetland swamp on the north and south side of the proposed excavation, located 100 feet from the excavation edge, running parallel to the affected area boundary. The operator will establish a 50ft undisturbed buffer (no disturbance of any kind) between the southwest boundary of the affected area and the adjacent wetland area. This buffer will be maintained by the operator as pasture with grass and pine tree ground cover. In addition, there will be a 50ft 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 a constructed 6ft wide drainage ditch that leads 25 feet to a field irrigation and drainage ditch, then 75 feet to wetlands and then 1200 to the Perquimans River. Overflow into the outfall ditch will be stabilized by riprap installed in the 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 8ft 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, the majority 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 10 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 1200 feet to wetlands leading to Perquimans River. 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 River Farms 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 permitteewill utilize best management practices to ensure that dewatering the River Farms 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. 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.
