Harris, President, 534 N. Slope Rd., Roper, NC 27970 Job Location: Harris Farms Inc. Mine, SR 1126 Newland Road, Roper, NC 27970 County: Washington County Prepared by: Ken Elliott, consulting Date: April 3, 2022 This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures used for dewatering the Harris Farms Inc. Mine safely, and that dewatering will not degrade or negatively impact any wetlands or waters of the state. Description and Current State of the Harris Farms Mine Site and Mining Application: Harris Farms Inc. Mine is a proposed 12.14-acre sand mine excavation to be operated by Harris Farms Inc., Michael D. Harris, owner & operator, in a 14.61-acre permit area located 0.5 miles northeast of Roper, NC on Newland Road in Washington County. The permit area is on cultivated, sandy land at 30-ft to 13-ft elevation, owned by Michael D. Harris, located 300 feet north of a canal/tributary of the Albemarle Sound. Currently Mr. Harris is applying for a modification to his existing mining permit #94-20 with the NCDEQ Division of Energy, Mineral and Land Resources to construct the sand mine and begin operation in April or May 2022. A new NPDES General Permit application for dewatering is being submitted to NCDEQ, registration for water usage has been submitted to the Division of Water Resources, and a Stormwater Pollution Prevention Plan is in process of development. Sand Mine Dewatering: It will be necessary to dewater the pond as it is being excavated to allow excavating equipment to enter the area safely and efficiently remove the sand from the pond bottom. This will allow for full permitted depth of excavation of the pond and proper reclamation of the edges of the pond. It is the intention of the operator to only dewater the excavation as needed, which will not entail full-time dewatering. Dewatering rate will be regulated using low rpm pumping, maintaining an average of 1100 rpm for 12 hours per day. Pumping rate will be approximately 7980 gallons per hour (95,760. gallons per 12-hr day, 0.096 mgd). The operator plans to dewater intermittently three to four times per year to excavate approximately 25,000 cubic yards of sand at a time and stockpile it for later usage. Once the stockpiled sand is depleted, the operator will dewater the excavation again and remove another quantity of sand. Mine dewatering wastewater will be treated before release to the Waters of the State. A sedimentation pond separate from the excavated mine will be used to remove sediment from wastewater generated during mine dewatering operations. Sedimentation Pond Construction and Overflow Discharge: The operator plans to construct a 0.18-acre in -ground sedimentation pond located inside the north end of the excavation area. The pond will have 4-ft tall sand berms around the pond with 3:1 exterior slope and full groundcover. Pond will be located between the proposed mine site field and a 16-ft wide groundwater leveling ditch into which the sediment pond will overflow during dewatering activity. This ditch drains 1700 feet to the Roper Main Canal (classified C; Sw), then draining 0.9 mile to Kendrick Creek (C), and thence draining 4.6 miles to Albemarle Sound (SB). Sediment pond water level will be controlled by a half -pipe flash -board water height control device installed in the east corner of the sediment pond berm. This control structure will allow water to flow across the flash boards into a 25ft long x 15" wide buried PVC discharge pipe running westward through the berm 20 feet to a discharge outlet in the groundwater levelling ditch. Dewatering Procedure: The operator will install a 6-inch dewatering pump between the main excavation and sediment pond at the north edge of the excavation. Discharge from the dewatering pump will enter the sediment pond on its northwest end, and there will be a constructed half -pipe flash board water height control device (see attached diagram) discharge point located on the east end of the sediment pond. Water will be pumped from the excavated pond to the sediment pond by the 6-in diesel fuel -powered transfer pump operating at idle speed, approximately 1100 rpm. Estimated maximum flow from the pump will be 8,000 gallons/hour, operating 12 hours per day, 0.096-mgd. It is the intention of Mr. Harris to drop the water level in the excavation approximately 20 - 25 feet below normal ground level as needed. 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 150 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 a surrounding 2-ft tall sediment pond berm. Groundwater Control: Once dewatered, excavation activity will be focused on removing sand as quickly as possible to shorten the periods of dewatering. This will allow groundwater level in the pond to return to normal as soon as possible to lessen possible impacts to any adjacent wetlands, once dewatering ceases. Groundwater levels are not expected to impact areas outside of the immediate excavated dewatering area. Groundwater levels are expected to remain stable despite dewatering of the excavation. The excavation site is surrounded on three sides by ditches and canals kept naturally full by direct drainage connection to Albemarle Sound. Because of intermittent dewatering and presence of nearby canals, groundwater level depletion is not expected to affect any neighboring groundwater wells. The closest residence to excavation is located 150 feet from the proposed excavation. The area is served by the Washington County Water System. The operator also proposes to install two groundwater level monitoring wells between the proposed excavation area and adjacent residences on the west end of the permit area (see mine map for proposed locations). Because of proximity of residences to the proposed excavation, the operator is providing a performance guarantee to repair or replace in -use groundwater wells or pumps at eleven homes located within 500 feet of the proposed excavation if they are impacted by dewatering activities at the Harris Farms Inc. Mine. Sedimentation and Erosion Control: The operator will maintain a minimum 25-ft wide unexcavated buffer on the north, south, east, and west sides of excavation activity and a 40-ft wide unexcavated buffer on the southwest side. All erosion and sedimentation will remain inside the permit area. The operator will construct and maintain an 8-ft wide x 2-ft tall grass -covered sand berm around the perimeter of the current affected area of the excavation during all phases of operation, inside the unexcavated buffer. Stormwater falling inside the active mining area will be directed to drain into the excavation. Maintaining the Dewatering Equipment and Erosion Control Measures: Inspections and maintenance are required to obtain the intended function of safely dewatering the sand mine, and to maintain the life of any nearby wetlands or waters of the State. Items to inspect and maintain during the anticipated 10-year life of the mine dewatering permit are: • Inspect embankments, berms and appurtenant structures, and repair as needed. • Monitor overflow ditches for damage or stoppage from beaver activity, repair as needed. • Repair any damage to vegetated areas or berms with compacted earth fill, reshaping, sodding, reseeding, and mulching as needed. • 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 manufacturers recommendations Monitoring the Dewatering Process and Effects of Dewatering: Analytical and qualitative monitoring of mine dewatering wastewater will be in accordance with the NCGO20000 permit, as follows: • Harris Farms Inc. Mine will discharge mine dewatering wastewater into Roper Main Canal, classified as C;Sw, and Kendrick Creek, classified as C. Discharge water will be analyzed quarterly per requirements of the NPDES permit. • Discharge water will be sampled quarterly and analyzed for pH, Total Suspended Solids (TSS), turbidity, and salinity. Samples with benchmark exceedances will require the operator to increase sampling, per NPDES permit, until sample results are cleared. • All excavated ponds in the Harris Farms Inc. Mine permit area will be inspected daily by the operator to identify any abnormal conditions. • All berms and erosion 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. • Rain gauge data will be collected by monitoring local rain gauge data monthly and after each rain event. Wetlands Monitoring: Closest identified wetlands are located 500 feet south of the Harris Farms Inc. Mine permit boundary, separated from the mine site by the permanently flooded Roper Main Canal. There are no other wetlands on the Harris Farms permit area. Flooded ditches such as the Roper Main Canal and drainage ditches around the mine site will serve as hydration devices to help maintain normal groundwater levels. Operator will monitor drainage ditches weekly to always ensure presence of water in the ditch. Records Data will be collected as follows: • 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. DWQwill 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 Harris Farms Inc. Mine will not degrade or negatively impact any wetlands or waters of the State. BMP's will include: 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 Temporary gravel construction entrance will be maintained at foot of mine access roads at intersection with Newland Road. o Operator will maintain riprap outfall protection on the overflow drainage ditch downstream of sediment pond. o Groundcover will be established on all sections of the permit area when not in use by mining activities.

Mine Roper, NC Washington County emargericY spillway !--- 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 east berm of the sedimentation pond at the Harris Farms Inc. Mine. Overflow to be directed down stabilized ditch to nearby blue -line stream, eventual outflow to 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 the Harris Farms Inc. Mine, Newland Road, Roper, NC. Sedimentation pond is a part of the dewatering management system of the Harris Farms Inc. Mine, used to remove settleable matter and turbidity from mine dewatering wastewater. CONSTRUCTION Typical 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 February 18, 2022 ELLIOTT CONSULTING March 26, 2022 NC Department of Environmental Quality Division of Energy, Mineral and Land Resources Land Quality Section 1612 Mail Service Center Raleigh, NC 27699-1612 To Whom It May Concern: This Mining Permit application is a request by Mr. Michael D. Harris, president of Harris Farms, Inc, Roper, NC, to excavate a 12.14-acre pond on property owned by Mr. Harris, off SR 1126 Newland Road, Roper, NC, in Washington County. The proposed permit area is in a flat, sandy, cultivated farmland, and will not present any problems regarding runoff to adjacent areas when all proposed erosion and sediment control measures are in place. The purpose of the excavation will be to serve as scenic value and to return the disturbed lands around the pond to agricultural status. The proposed Harris Farms Inc. Mine originates from a modification of the existing Permit #94-20 Harris Farms Inc. Mine. The existing 24.0-acre permit contains 16.85 acres of farmland and woodland that have never been disturbed by mining activity, and the operator desires to remove this land from his permit. In addition, the operator desires to add 7.28 acres of excavation area to his permit located westward and adjacent to the existing 4.86-acre excavation for easier accessibility. Total excavation will now be 12.14 acres in a 14.61-acte permit area. The operator proposes to dewater the excavation as part of the mining process and proposes the installation of two groundwater -level monitoring wells between the excavation and adjacent homes southwest of the excavation. The wells will be monitored regularly to inform the operator of potential disruption of groundwater levels. The excavation area will be located geographically 225 feet from the nearest public highway and will be accessible only by two privately -owned access roads. Excavation activities will be screened from public view on all sides by existing full -growth foliage and a 6-foot tall, foliated berm between the mine activity area and two residences nearby.

Mr. Harris is applying to NCDEQ Division of Energy, Mineral and Land Resources for the modification to his mining permit, and for an NPDES NCG020000 Certificate of Coverage for dewatering the mine. In addition, he is registering with the Division of Water Resources for water usage in Washington County, which is a CCPCUA county. -2— March 26, 2022 Reclamation of the permit area will include grading, leveling, and establishment of groundcover on all affected areas. The mining permit is requested for a 10-year period. All adjacent landowners have been contacted and made aware of the proposed excavation operation. Requests for information have been received but with no objections to the project. The excavation area will be well marked with warning and keep out signs to prevent inadvertent public access. Mr. Michael D. Harris does hereby request approval for this Mining Permit and asks that it be expedited as soon as possible. Mr. Harris appreciates your consideration of this mine permit application. sincerely, A - Ken Elliott For Michael D. Harris Harris Farms, Inc.
