The purpose of this project is the creation of a sand pit mine for use by Lane Farms in an existing agriculture field. All mining operations and access paths will be on property owned by Lane Farms. The proposed sand mine will have a maximum depth of approximately 10 to 16 feet relative to natural ground level. The property is adjacent to the existing sand pit operated by S.T. Wooten Corporation (Permit #96-55), also on property owned by Lane Farms. No asphalt, concrete or impervious surfaces are proposed. 2. Approximately 56.94 acres of the 191.53 ac site owned by Lane Farms was recently rezoned for mine pit use (from RA-20 to Al). The rezoning line was established in the field by Dan Butler, PLS, of Butler Surveying, January 29, 2020. Horizontal Datum is NAD '83 NC State Plan Coordinates. Vertical Datum is NAVD 1988. 3. Additional boundary, topographical and adjacent owner information shown is for reference only and was obtained from Wayne County GIS. Land disturbance within any existing utility and other easements shall be secured by Owner prior to construction. 4. No location of property boundaries, easements, wetland delineation, flood zones or buffers was performed, and must be done by a Professional Land Surveyor. This document is NOT to be used as a geed of Easement, nor is it to be construed to permit the location, description, establishment or reestablishment of property lines or descriptions of land boundaries for conveyance. 5. All materials, construction, workmanship and mining operations shall meet the requirements of Wayne County, NCDEQ and the NC Mining Act of 1971, latest revisions. 6. Contractor shall comply with all pertinent provisions of the "Manual of Accident Prevention in Construction" issued by AGC of America, Inc., and the Safety and Health Regulations for Construction issued by the U.S. Department of Labor. 7. No construction or mining operations may begin until an NCDEQ operating permit is received. All mining operations, inspections, reports, etc., shall be in accordance with the approved permit. NCDEQ Washington Regional Office can be reached at 252-946-6481, contact 5amir Dumpor, PE, Regional Engineer (252.948.3859). 8. EXISTING UTILITIES a. The Contractor shall be responsible for reviewing and verifying all existing site conditions. Any adverse existing conditions affecting work shown shall be brought to the attention of the Engineer far possible clarification or reconciliation. b_ Existing utility locations shown are approximate and shall be verified in the field by Contractor prior to beginning work. Contractor shall contact the 811 One Call Center and private utility locating firm for determination of locations of existing utilities minimum 72 hours prior to beginning construction. c. THE CONTRACTOR SHALL BE RESPONSIBLE FOR FIELD VERIFICATION OF THE LOCATION AND DEPTH OF ALL UTILITIES AND STRUCTURES WHICH CROSS THE WORK SITE OR WHICH MAY BE AFFECTED BY HIS OPERATIONS. d. Contractor is responsible for determination or discovery of existing underground storage tanks (UST), septic tanks, abandoned utility lines, graves, cemeteries, debris and unclassified fill that may exist on the site. e. Contractor shall exercise extreme caution when working under, around, and/or adjacent to existing power lines. 9. ENVIRONMENTAL a. FLOODPLAIN: The site is located within 100-year Floodplain per FEMA Map 3720.3506.00J, dated 12/02/05. The site drains to the northeast into agricultural fields or wooded areas toward the Neuse River. Approximately 100-yr flood elevation at this location is 68.4'. b. No riparian buffers, wetlands or streams are in the project area or will be disturbed for this project. 10. EROSION CONTROL: a. Contractor is responsible for containing all erosion and sedimentation within the project limits. Maintain site in a condition to prevent mud or sediment from leaving the construction site. b. See Erosion Control Narrative and Seeding Notes. MINE PERMIT NOTES Los[ Revised 2120120 I. No construction or mining operations may begin until an NCDEQ operating permit is received. All mining operations, inspections, reports, etc., shall be in accordance with the approved permit- 2. All areas within the permitted boundary are owned and maintained by Lane Farms, Inc. 3. The proposed sand mine will be constructed using excavators, front-end loaders, trucks, etc. 4. Proposed contours shown are approximate and may be field adjusted as coordinated with Engineer. However, excavation into the permit 25' internal buffer or beyond the limits of the permit boundary will require a revised NCDEQ approved Mining Permit. PROTECTION OF NATURAL RESOURCES: 5. Refer to Construction Sequence and Erosion Control Narrative. 6. Mining operations will not involve washing the material mined, recycling process water, or other waste water handling. 7. Mining operations will not involve discharging fresh or waste water from the mine or plant as a point discharge to the waters of the State. 8. Part of the proposed mine excavations) extend below the water table, but no dewatering is proposed. Those areas below the SHWT will be excavated during drier summer months when the water table is lower. The pit will be graded to divert flow to the center of the site where the water will pond until it seeps into the sand. There are no known wells within 500 feet of the proposed excavation area and no residences located within 1,800 feet. The existing shooting range does not have well or septic, but is served by portable toilet. 9. Mining operations will not involve crushing or any other air contaminant emissions. 10. Dust from stockpiles, haul roads, etc., will be controlled by watering as needed from water truck. 11. A 25-foot unexcavated buffer will be maintained between the mining permit boundary and the area of excavation. 12. There are no natural watercourses or wetlands within the permitted boundary. 13. To prevent landslide or slope instability, excavation will occur at 3:1 slopes. 14. See proposed cross sections on the plans. 15. To prevent physical hazard to any neighboring facility, a 4 foot high chain -link fence with gate will be maintained along the southern perimeter of the permit boundary along the existing gravel access road at NC 581. The remaining perimeter of the permit boundary is adjacent to wooded areas or topography that restricts access. The 58.56 acres is surrounded by the larger 191.53 acres owned by Lane Farms. 16. There are no houses within 300 feet of any proposed excavation, in fact, the nearest residence is more than 1,800 feet (Y mile) from the permit boundary. The nearest structure is located more than 600 feet from the permitted boundary, and are shelters for the shooting range also located on the 191.53 acres owned by Lane Farms. The existing 5-acre shooting range is separated from the mine by several existing berms, wooded areas and the proposed chain -link fence along the access road. 17. There are no known acid producing minerals or soils present at the site. 18, Screening: Much of the site is screened from public view by existing woods. A proposed 4' fence will be installed prior to operation along the existing gravel drive along NC 581. 19. There are no publicly owned parks, forests or recreation areas within sight of the mining operation that would be adversely affected by the sand pit. The mine will operate during daylight hours, preventing a noise nuisance. 20. No explosives will be used for excavation. 21. No fuel tanks, solvents, or other chemical reagents be stored on -site. RECLAMATION PLAN 22. No sediment ponds or sediment control basins are proposed on the mine site. The reclamation process will include maintaining grassed vegetation along the buffer area as described in section D-7 of this application. The bottom of the mining pit will fill with silt and organic detritus over time and hold water to a depth of at least 5 feet. The fence installed along the southern perimeter of the permit boundary will remain as a permanent barricade 23. An excavated body of water will be left as a part of the reclamation. Minimum water depth will be at least 5 feet. The body of water will not be stocked with fish. 24. The fence installed along the southern perimeter of the permit boundary will remain as a permanent barricade 25. No mine waste is planned for this site. 26. No processing facilities are proposed. Topsoil stockpiles will be removed upon completion of the sand pit. Temporary roadway ramps used to access the excavation area and portions of existing farm paths within the excavation limits will be consumed by mining. With the exception of the existing gravel access drive along NC 581 (located outside the permit boundary), no on -site roadways will remain upon completion of mining operations. 27. No on -site roadways will be left as part of the reclamation. 28. No off -site generated waste shall be disposed of on the mine site without prior written approval from the NC Division of Energy, Mineral, and Land Resources and either the Division of Waste Management (DWM) or local governing body. 29. Waste products and mine refuse will be hauled off -site to a permitted disposal facility. 30. Referto Erosion Control Narrative for seeding timeframes and specifications.

MAINTENANCE The Contractor is responsible for control of sediment on site until the project is handed over to the Owner. If erosion and sedimentation control measures shown on the plans prove insufficient, additional steps must be taken to stop sediment from leaving this site. Adequate and appropriate measures must be properly installed within the limits of disturbance to prevent sediment from leaving the site, entering existing drainage systems, and impacting natural watercourses or adjoining property. These plans are for bidding purposes only and are not to be used as Construction drawings unless initialed and dated as approved for Construction below by the Engineer. Approved for Construction: Date: Each sediment storage device must be inspected after each storm event. Maintenance and/or cleanout is necessary anytime the device is at 50% capacity. All sediment storage measures will remain on site and functional until all grading and final landscaping of the project is complete. Specifc maintenance requirements are shown below: A. DENUDED AREAS/GRADING: 1. Periodically, check all graded areas and the supporting erosion and sedimentation control practices, especially after heavy rainfalls. 2. Promptly remove all sediment from diversions and other water -disposal practices. 3. If washouts or breaks occur, repair them immediately. 4. Prompt maintenance of small eroded areas before they become significant gullies is an essential part of an effective erosion and sedimentation control plan. B. CONSTRUCTION ENTRANCE 1. Maintain the gravel pad in a condition to prevent mud or sediment from leaving the construction site. This may require periodic topdressing with 2-inch stone. 2- After each rainfall, inspect any structure used to trap sediment and clean it out as necessary. Immediately remove all objectionable materials spilled, washed, or tracked onto public roadways. C. ROLLED EROSION CONTROL PRODUCTS 1. Inspect Rolled Erosion Control Products at least weekly and after each significant (1/2 inch or greater) rain fall event repair immediately. 2. Good contact with the ground must be maintained, and erosion must not occur beneath the RECP. 3. Any areas of the RECP that are damaged or not in close contact with the ground shall be repaired and stapled. 4. If erosion occurs due to poorly controlled drainage, the problem shall be fixed and the eroded area protected. 5. Monitor and repair the RECP as necessary until ground cover is established. D. TEMPORARY DIVERSIONS 1. Inspect temporary diversions once a week and after every rainfall. Immediately remove sediment from the flow area and repair the diversion ridge. 2. Carefully check outlets and make timely repairs as needed. 3. When the area protected is permanently stabilized, remove the ridge and the channel to blend with the natural ground level and appropriately stabilize it. E. PERMANENT DIVERSIONS 1. Inspect permanent diversions after every rainfall during the construction operation. Immediately remove any obstructions from the flow area, and repair the diversion ridge. RECORD DRAWINGS: These drawings are believed to be a correct representation of actual field conditions but are not warranted as such. BOUNDARY DESCRIPTION SHOWN IS NOT FOR RECORDATION. By: Date: 2. Check outlets, and make timely repairs as needed. 3. Maintain the vegetation in a vigorous, healthy condition at all times. F. GRASS -LINED CHANNELS 1. During the establishment period, check grass -lined channels after every rainfall. After grass is established, periodically check the channel; check it after every heavy rainfall event. Immediately make repairs. 2. It is particularly important to check the channel outlet and all road crossings for bank stability and evidence of piping or scour holes. 3. Remove all significant sediment accumulations to maintain the designed carrying capacity. 4. Keep the grass in a healthy, vigorous condition at all times, since it is the primary erosion protection for the channel. G. ROCK -LINED CHANNELS 1. Inspect channels at regular intervals as well as after major rains, and make repairs promptly. Give special attention to the outlet and inlet sections and other points where concentrated flow enters. 2. Carefully check stability at road crossings, and look for indications of piping, scour holes, or bank failures. Make repairs immediately. 3. Maintain all vegetation adjacent to the channel in a healthy, vigorous condition to protect the area from erosion and scour during out -of -bank flow. 4. Riprap should be inspected after every significant rainfall event periodically for scour or dislodged stones. Ensure good control of weeds and vegetation. H. OUTLET PROTECTION 1. Inspect riprap outlets weekly and after significant (1/2 inch or greater) rainfall events to see if any erosion around or below the riprap has taken place, or if stones have been dislodged. Immediately make all needed repairs to prevent further damage. I. HORSEHOE ROCK PIPE INLET PROTECTION 1. aka ROCK PIPE INLET SEDIMENT TRAP TYPE A/B (NCDOT 1635.01, 1635.02) 2. Inspect rock pipe inlet protection at least weekly and after each significant (% inch or greater) rainfall event and repair immediately. 3. Remove sediment and restore the sediment storage area to its original dimensions when the sediment has accumulated to one-half the design depth of the trap. Place the sediment that is removed in the designated disposal area and replace the contaminated part of the gravel facing. Check the structure for damage. Any riprap displaced from the stone horseshoe must be replaced immediately. 4. After all the sediment -producing areas have been permanently stabilized, remove the structure and all the unstable sediment. Smooth the area to blend with the adjoining areas and provide permanent ground cover. J. SEDIMENT FENCE/ SILT FENCE 1. Inspect at least weekly and after each significant (1/2 inch or greater) rainfall event and repair immediately. 2. Should the fabric of a sediment fence collapse, tear, decompose or become ineffective, replace it promptly. 3. Removed sediment deposits as necessary to provide adequate storage volume for the next rain and to reduce pressure on the fence. Take care to avoid undermining the fence during cleanout. 4. 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. K. SILT FENCE OUTLET 1. Inspect at least weekly and after each significant (1/2 inch or greater) rainfall for damage and sediment accumulation to confirm device is working properly. 2. At a minimum, remove sediment when accumulation reaches half the height of sediment control stone. 3. Replace or clean sediment control stone as needed to allow water to drain through the device between rainfall events. 4. Rebuild and/or repair the device when damaged. 5. Repair areas that become undermined due to concentrated flows. 6. 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. L. SKIMMER SEDIMENT BASIN (no riser) 1. Inspect basin at least weekly and after each significant (1/2 inch or greater) rainfall event and repair immediately. Remove sediment and restore original volume when sediment accumulates to about one-half the design volume. Sediment should be placed above the basin and adequately stabilized. 2. Pull the skimmer to one side so that the sediment underneath it can be excavated. Excavate sediment from the entire basin, not just around the skimmer or the first cell. Make sure vegetation growing in the bottom does not hold down the skimmer. 3. Repair the baffles if they are damaged. Re -anchor baffles if water is flowing underneath or around them. 4. If the skimmer is clogged with trash and there is water in the basin, usually jerking on the rope will make the skimmer bob up and down and dislodge the debris and restore flow. If this does not work, pull the skimmer over to the side and remove debris. Also, check the orifice inside the skimmer to see if it is clogged; if so remove debris. 5. If the skimmer arm or barrel pipe is clogged, the orifice can be removed and obstruction cleared with a plumber's snake or by flushing with water. Be sure and replace the orifice before repositioning the skimmer. 6. Check the embankment, spillways, and outlet for erosion, piping, and settlement and repair immediately. Remove all trash and other debris from the skimmer and pool areas. 7. Remove the structure and any unstable sediment immediately after the construction site has been permanently stabilized. Smooth the basin site to blend with the surrounding area and stabilize. All water and sediment should be removed from the basin prior to dam removal. 8. Sediment should be placed in designated disposal areas and not allowed to flow into streams or drainage ways during structure removal. M. BAFFLES 1. Inspect baffles at least once a week and after each rainfall. Make any required repairs immediately. 2. Be sure to maintain access to the baffles. Should the fabric of a baffle collapse, tear, decompose, or become ineffective, replace it promptly. 3. Remove sediment deposits when it reaches half full, to provide adequate storage volume for the next rain and to reduce pressure on the baffles. 4. Take care to avoid damaging the baffles during cleanout, and replace if damaged during cleanout operations. Sediment depth should never exceed half the designed storage depth. 5. After the contributing drainage area has been properly stabilized, remove all baffle materials and unstable sediment deposits, bring the area to grade, and stabilize it. N. CHECK DAM 1. Inspect at least weekly and after each significant (1/2 inch or greater) rainfall event and repair immediately. Remove sediment, straw, limbs, or other debris that could clog the channel when needed. � I 'o ¢ � U 2. Anticipate submergence and deposition above the check dam and erosion from high flows around the edges of the dam. Correct all drainage immediately. If significant erosion occurs } Q7 between dams, additional measure can be taken such as installing protective riprap liner in that portion of the channel. z N 3. Add stones to the dam as needed to maintain design height and cross section. Q 4. All stone armor protection is to fit contour of channel. Do not dump but hand spread. 0 5. Remove sediment accumulated behind the dams as needed to prevent damage to channel v o vegetation, allow the channel to drain through the stone check dam and prevent large flows Z 0 from carrying sediment over the dam. Place rock from rock check dams and temporary T O_ a sediment traps in roadside ditch as armor protection. Do not dispose of rock. ir In N o O.

All gullies, rills and any other disturbed areas must be fine graded prior to installation. 2. Lime, fertilize and seed BEFORE installation of RECP. Planting of shrubs, trees, etc. (if required) should occur after installation. 3. Anchor Trench: Anchor trenches are required to securely fasten the RECP to the ground surface. Cut trenches for initial anchor trenches, termination trench and side anchor trenches (6 inches wide and 12 inches in depth) as shown in Detail D_ Position initial and terminal anchor trenches 3' back from the crest/bank/toe of the slope. Install the RECP into the trench, fasten to the bottom with staples/pins spaces 3 feet apart (maximum). Backfill the trenches and compact in a manner that does not damage the RECP. 4. Terminal trenches are required at RECP ends and intermittenttrench es must be constructed across channels at 25-foot intervals. Check slots and stapling layout to be constructed per manufacturers specifications. 5. Once anchored at the top, roll the RECP down the slope. Install staples/pins dawn the center of each mat with spacing interval of 3 feet minimum. More fasteners may be required depending on the application, the slope and the soil type. See Detail A for the rule of thumb on the number of fasteners needed. 6. If overlapping from end to end as necessary, ensure the rolls are shingled in the direction of the waterflow, upslope over downslope (see drawing below for clarity).

These notes are intended to comply with NCDEQ LQS Erosion Control Manual practice 6.64, Skimmer Sediment Basin. INSTALLATION 1. Strip area under embankment of all vegetation and root mat. Place temporary sediment control measures (silt fence) below basin as needed. 2. Ensure that fill material for the embankment is free of roots, woody vegetation, oversize stones, organic material, or other objectionable material. Place fill in lifts of 9" or less and compact by traversing. Overfill embankment 6" to allow for settlement. 3. Shape the basin as shown on the plans. Ensure stable transition from diversion to toe of basin slope, using fiberglass netting or rip rap, if required. 4. Place barrel (4" Sch 40 PVC pipe, unless otherwise noted) on a firm, smooth foundation of impervious soil. DO not use pervious material such as sand, gravel or crushed stone as backfill around pipe. Place the fill material around the pipe spillway in 4" layers and compact it under and around the pipe to at least the same density as the adjacent embankment. 5. Place a minimum of 2' of compacted backfill over the pipe spillway before crossing it with construction equipment. In no case should the pipe conduit be installed by cutting through the dam after the embankment is complete. Provide seeding and matting an interior and exterior sideslopes. 6. EMERGENCY SPILLWAY: Install low permeability, woven polypropylene geotextile for spillway liner per NCDOT Specs Sec. 1056 (Type 4 geotextile). Unroll the geotextile on the spillway in the direction of flow, with edges buried at least 6 inches. Geotextile to be one continuous piece of material or overlapped a minimum of 18 inches. 7. Install coir baffles as shown per Detail 102.11, or field adjust as necessary with approval from Engineer. 8. Prevent the skimming device from settling into the mud by providing a foot pad of Class B rip rap (min. 4' x 4' x V) under the skimmer, or approved equivalent method. 9. Assemble the skimmer following the manufacturer's instructions or as designed. 10. Lay the assembled skimmer on the bottom of the basin with the flexible joint at the inlet of the barrel pipe. Attach the flexible joint to the barrel pipe and position the skimmer over the rock foot pad. 11. Attach a rope to the skimmer and anchor by rope to a wood stake or metal post for maintenance. MAINTENANCE OF SKIMMER BASIN 12. Inspect skimmer basin at least weekly and after each significant ('/z" or greater) rainfall event and repair immediately. Remove sediment and restore the basin to its original dimensions when sediment accumulates to YZ the height of the first baffle. Pull the skimmer to one side so that the sediment underneath it can be excavated. Excavate sediment from the entire basin, not just around the skimmer or the first cell. Make sure vegetation growing in the bottom of basin does not hold down the skimmer. Ensure rock foot pad is clear of silt. 13. Repair baffles if damaged. Re -anchor baffles if water is flowing underneath or around them. 14. If skimmer is clogged with trash and there is water in the basin, usually jerking an the rope will make the skimmer bob up and down and dislodge debris and restore flow. If this does not work, pull the skimmer over to the side of the basin and remove the debris. Also check the orifice inside the skimmer to see if it is clogged; if so, remove the debris. 15. If skimmer arm or barrel pipe is clogged, the orifice can be removed and the obstruction cleared with a plumber's snake of by flushing with water. Be sure and replace the orifice before repositioning the skimmer. 16. Check the embankment, rock spillway and outlet for erosion damage, and inspect the embankment for piping and settlement. Make all necessary repairs immediately. Remove all trash and other debris from the skimmer and pool areas. 17. Maintenance of the sediment basin/ rock dam is only to be performed by authorized personnel. 18. Contractor is to maintain record of inspections, maintenance and dewatering records on Self -Inspection Forms and NCG permit forms in the permit box kept ansite. SEDIMENT BASIN REMOVAL PROCEDURE 19.

THE SLOPE FACE SHOULD NOT BE BACK - BLADED DURING THE FINAL GRADING OPERATION. SEDp I F � � s � r NOTES: 1. CUT SLOPE ROUGHENING FOR AREAS NOT TO BE MOWED a. Stair -step grade or groove cut slopes with a gradient steeper than 3:1. Use stair -step grading on any erodible material soft enough to be ripped with a bulldozer. Slopes consisting of soft rock with some subsoil are particularly suited to stair -step grading. b. Make the vertical cut distance less than the horizontal distance, and slightly slope the horizontal position of the "step" in toward the vertical wall. c. Do not make individual vertical cuts more than 2 feet in soft materials or more than 3 feet in rocky materials. d. Grooving uses machinery to create a series Of ridges and depressions that run across the slope (on the Contour). Groove using any appropriate implement that can be safely operated on the slope, such as disks, tillers, spring harrows, or the teeth on a front-end loader bucket. Do not make such grooves less than 3 inches deep nor more than 15 inches apart. 2. FILL SLOPE ROUGHENING FOR AREAS NOT TO BE MOWED a. Place fill slopes with a gradient steeper than 3:1 in lifts not to exceed 9 inches, and make sure each lift is properly compacted. Ensure that the face of the slope consists of loose, uncompacted fill 4 to 6 inches deep. Use grooving, as described above, to roughen the face of the slopes, if necessary. Do not blade or scrape the final Slope face. 3. CUTS, FILLS, AND GRADED AREAS THAT WILL BE MOWED a. Make mowed slopes no steeper than 3:1. b. Roughen these areas to shallow grooves by normal tilling, disking, harrowing, or use of cultipacker-seeder. Make the final pass Of any such tillage implement on the contour. c. Make grooves, formed by such implements, close together (less than 10 inches) and not less than 1 inch deep. d. Excessive roughness is undesirable where mowing is planned. 4. ROUGHENING WITH TRACKED MACHINERY a. Limit roughening with tracked machinery to sandy soils to avoid undue compaction of the soil surface. Tracking is generally not as effective as the other roughening methods described. b. Operate tracked machinery up and down the slope to leave horizontal depressions in the soil. Do not back -blade during the final grading operation. 5. SEEDING Immediately seed and mulch roughened areas to obtain optimum seed germination and growth. MAINTENANCE: Periodically check the seeded slopes for rills and washes. Fill these areas slightly above the original grade, then reseed and mulch as soon as possible. 107.01 - SURFACE ROUGHENING BY TRACKING NOT TO SCALE REV. 11-19-19 � I a 'o ¢ � U �r 0 a w � o v N Z o o O a � T - o V U V] o Y UJ n � w o a o = Q Z z w Ln o a � n V L] N N `V o se O _ � z "vinnr 4 CONSULTING ENGINEERS, P.A.
