This O&M Plan is intended to address the following issues: e Pump Maintenance and Recording, ■ Groundwater Monitoring, ■ Wetlands Monitoring, ■ 5tormwater and Mining Permit Requirements, ■ Operating Record and Recordkeeping Requirements. Site Background The site is located in a relatively remote area of mainland Dare County. The existing borrow area is surrounded by wetlands and prior converted cropland currently utilized for agriculture. The entire Dare County site is bounded on the east by U.S. Highway 264 and on the other three sides by the Alligator River National Wildlife Refuge. The existing borrow area has been in operation since 1995 to provide cover soil for the active C&D landfill. The existing excavation started approximately 150 feet south of the canal adjacent to Cub Road, to minimize the effects of groundwater flow changes on the C&D landfill groundwater monitoring system, and has continued to be performed at an average of 18-20 feet below ground surface extending south toward Grouse Road (See attached Sheet C-1). Excavation is performed in increments as'necessary to supply base fill, daily cover, and cap construction for the C&D landfill. Dewatering of the excavation occurs as necessary. Excavated material is temporarily stockpiled in the stockpile area and, after adequate drainage, is used at the C&D landfill site. In accordance with the approved mining permit, as the final edges of the excavation pit are completed, excavation equipment operators will ensure that the final below water table surface slopes comply with the specifications outlined above. A free settling slope will be maintained on the active face until final excavation is complete. Warning signs are placed at the four corners of the excavation area. In the mining area, land disturbing activities are accomplished such that all stormwater runoff are directed into the mining pit. Drainage into the southern mining pit (Mining Excavation Pit 3) drains north where it is pumped into Mining Excavation Pit 2. Mining Excavation Pit 2 gravity drains into Mining Excavation Pit 1. All water discharged from Mining Pit 1 gravity drains from the discharge of Mining Pit 1 and flows west along Cub Road. At the intersection of Cub Road and Bear Road, drainage is directed north.and discharges from the property at the intersection of Bear Road and Gadwell Road. Two surface drainage ditches drain the L~ � PXD—_C.,*p 17p5ZO—Pt olY PL.Wt—d rk &rtyw Pv CMW P4PjY4_]WIN' 7 COLS 1-1 Dare County C&D Landfill sorrow Pit Operation and Maintenance Plan stockpile area. Sedimentation basins are constructed in each of the two ditches to treat stormwater and soil drainage. Based on pump curve data, it'is estimated that the maximum discharge rate for the dewatering operation at the pit is approximately 1,200 gpm or 1.7 MGD. it is likely that discharge rates are typically lower than 1,200 gpm and vary based on head. Withdrawn water from the current excavation (Pit 3) is pumped to an adjacent pit and ultimately discharges to a series of canals on site, as described above. O&M Procedures The following sections discuss 0&M procedures to be followed for the borrow pit activities at the site. A spreadsheet to be used as a weekly general inspection checklist has been generated based on the following activities. The weekly inspection checklist is provided as Table 1. The weekly general inspection checklists will be maintained in a dedicated folder or file and kept in the scale house. In addition, as required in the Mining Permit, qualitative inspection and analytical discharge monitoring will be conducted at the outfall from Mining Pit 1 to the canal. A Stormwater Discharge Outfall (SDO) Qualitative Inspection Monitoring form is attached. The qualitative inspection monitoring form is to be completed weekly and during any storm event greater than 0.10 inches and will be kept on file in the scale house. If no discharge occurs during that period, the Form should be filled out as "no flow." Pump Maintenance and Recording There is no meter present to monitor discharge rates from the borrow pit to the adjacent pit, however, there is an hour meter at the pump. Pumping rates vary as head fluctuates, but the pump is never turned off. In the event of interruption or variation from the typical pumping rate and time, County staff shall record time that pump was not active and describe reason for inactivity on the weekly inspection checklist. Groundwater Monitoring In order to monitor the effects of prolonged pumping of the surficial aquifer on the area surrounding the borrow pit, 4 new monitoring wells have been installed (Well-1 through Well-4). The wells were surveyed to State Plane coordinates and NAVD 88 elevation. Well locations are shown on the attached Wetland Flag Location Map. Water levels in the wells are to be measured from the top of the PVC casing quarterly. All water measurements shall be recorded on the corresponding weekly inspection checklist. Wetlands Monitoring The wetland areas adjacent to the morrow pit have been flagged and mapped (see attached Wetland flag location Map). These areas and the adjacent ditches are to be visually inspected for signs of vegetative stress or abnormality and water level/flow within the ditches on a weekly basis. All observations from the weekly wetland inspections shall be recorded on the weekly inspection form. 1-2 a+oa.a twr+y+»sTBeno-w v�oau%OpewW 0. ea"P4 aw Ptwk-FmW_102+20+t ooa Dare County C&D Landfill Borrow Pit Operation and Maintenance Plan Stormwater Qualitative inspection Monitoring Stormwater qualitative inspection monitoring shall be conducted at the outfall from Mining Pit 1 weekly and during any storm event greater than 0.10 inches. Qualitative inspection monitoring shall include descriptions and observations made at the outfall and include: Color; odor; clarity; floating solids; suspended solids; foam; oil sheen; indications of sediment deposition; indications of erosion; and any other obvious indication of stormwater pollution. if no discharge occurs for that period, the form shall be filled out as "no flow," All weekly qualitative inspections shall be recorded on the attached Stormwater Discharge Outfall (WO) Qualitative Inspection Monitoring form and kept on file in the scale house. If obvious indications of turbidity, erosion or sedimentation are observed, perform maintenance as necessary. Stormwater Analytical Monitoring Stormwater analytical monitoring shall be conducted at the outfall from Mining Pit 1 semi- annually during a representative storm event that causes discharge. Samples for Settleable Solids and Total Suspended Solids shall be collected and sent to an offsite laboratory for analysis. Field measurements of turbidity shall also be collected at the outfall during these events. Total Rainfall, Event Duration, and Total Flow shall also be recorded on the Stormwater Discharge Outfall (SDO) Qualitative Inspection Monitoring form. Semi-annual analytical data and rainfall data will be recorded on a Discharge Monitoring Form and kept on file in the scale house. However, if any parameter benchmark is exceeded for a semi-annual event, a Stormwater Exceedence DMR form will be forwarded to the Regional DWQ office within 30 days of receipt of the analytical data. Analytical results for the semi-annual events will be compiled in an Annual Discharge Monitoring Form for submittal to the Central DWQ office by March 1 of the following year. Semi-annual stormwater samples shall be collected between January 1—June 30 and July 1— December 31, with a minimum of 60 days between samples. Mine Dewatering Discharge Analytical Monitoring In addition to the semi-annual stormwater monitoring, quarterly analytical sampling must be conducted at the outfall to monitor general effluent quality from the dewatering activities. Samples are to be collected and analyzed for pH, Settleable Solids, Total Suspended Solids, and Turbidity. Total dewatering volume for the date'of sample collection must also be recorded. Pump volume can be estimated from pump hour recordings from Table 1 and pump curves. Quarterly effluent analytical data will be recorded on a Discharge Monitoring Form and will. be kept on file in the scale house. However, if any parameter limit is exceeded, or a violation is found for any quarterly event, an Effluent Exceedence DMR form will be forwarded to the Regional DWQ office within 30 days of receipt of the analytical data. Analytical results for the quarterly.events will be compiled in.an Annual Discharge Monitoring Form for submittal to the Central DWQ office by March 1 of the following year. 1-3 PIDu�cW 1TB'^�BvrtlrH WY PMWMMdC—hWowPrDAMPhn_F�g1_1RI��1d— Dare County CAD Landfill Borrow Pit Operation and Maintenance Plan Quarterly mine dewaterine samples shall be collected From the outfall as follows: • Q1 between January 1 and March 31, • Q2 between April 1 and June 30, • Q3 between July land September 30, • Q4 between October 1 and December 31. `e."0.i, 1-4 P%Dare_Cww'y1745MWI"Px Ot61 Plan'Rw.MDa,• Dwi PgOWFa%F—, _fMMItu - Table 1 Dare County C&D Landfill Borrow Pit Weekly Inspection Form Date General Weather Conditions Landfill Representative Borrow Pit Discharge Pump (to be monitored weekly) Pump Hours Comment: Pump Running Y 1 N Comment: Operational comments: (has pump operation remained constant since previous week and if not why) Groundwater Monitoring Wells (Elevations arerequired to be monitored quarterly) Well Tom - DoRtth to Wator From Top = Mw-1 2.65 - _ MW-2 8.62 - _ MW-3 4.58 - _ MWA 5.36 - _ Wetlands and Surface Water Observations (to be monitored weekly) Stressed.Vegetation Y I N Comment: WaterlFlow in Ditches Y I N Comment: Other Comments/Observations: GW Elevation Stormwater Discharge Outfall (SDO) Qualitative Monitoring Report Forgrtittattecotrfllitigozettlrisform,please risir: htlpa/}�2o.enrstate.nc.us/sillPorms_D��ruincnrs.hnn#miscfurms Permit No.: Facility Name: — County: Inspector: Date of Inspection: Time of Inspection: Total Event Precipitation (inches): or Certificate of Coverage No.: NICIGI I I_I_I_1^I Phone No. Was this a Representative Storm Event?

THIS APPLICATION WILL NOT BE CONSIDERED COMPLETE WITHOUT ALL RELEVANT ITEMS BEING ADEQUATELY ADDRESSED ON THE MINE MAPS. -5- APPLICATION FOR A MINING PERMIT C. PROTECTION OF NATURAL RESOURCES Describe in detail the sequence of events for the development and operation of the mine and reference the sequence to the mine map(s). Attach additional sheets as needed. The mine is located in a relatively remote area of Dare County as shown on Figures l and 2 with the site currently consisting of three pits. Pits #1 and #2 were completed years ago and have filled in with water with mining operations currently taking place in Pit #3. Pit #1 started approximately 150 feet south of the canal adjacent to Cub Road in order to minimize the effects of groundwater flow changes on the Construction & Demolition (C&D) landfill groundwater monitoring system. Mining is performed at an average depth of 18- 20 feet below mean sea level (msl) and extends south towards Grouse Road. A 25-foot buffer that is approximately 300 feet from the County's property line exists along the eastern woods line. The southern extent of the existing excavation has a 25-foot buffer from the woods line south of Grouse Road, and is approximately 1,150 feet from the County's property line. The current permit boundaries and current excavations are shown in Sheet C-l. A March 2010 survey of the mine is shown on Sheet C-2. Dcwatering of Pit #3 occurs as necessary and as defined in Section 3.b. of this permit. Excavated material is temporarily stockpiled in the stockpile area and after adequate drainage the soil is used for cover at the C&D landfill site. During excavation the uppermost organic layer is stripped and stockpiled separately at the C&D landfill site for future use as final C&D landfill capping material to support grass cover. Due to the sandy nature of the excavated material a free settling slope is maintained on active excavation surfaces. Upon completion of excavation the final slopes for the outer slopes will be 3:1 (I-I;V) as shown on Sheet D-I. All other existing slopes will be in accordance with the previous approved mining pert -nit. Upon completion of the excavation for a major portion of the outer face all above water table areas are stabilized with vegetative cover in accordance with the most recent Vegetation Plan, which was provided in the approved Erosion and Sedimentation Control Plan for Phase 4 of the C&D landfill. A copy of the approved plan is included in Appendix A. In accordance with the previous approved mining permit as the final edges of the excavation pit arc • completed excavation equipment operators will ensure that the final below water table surface slopes comply with the specifications outlined above. A free settling slope will be maintained on the active face until final ® excavation is complete. Warning signs are placed at the four corners of the excavation area. This permit modification is proposing to add an additional 47.5 acres as shown on Sheet C-3 to the southwest of the current excavation to provide additional material for use at the C&D landfill. Mining will progress in a similar fashion as the current excavation with mining performed in increments as necessary to supply base fill, daily cover, and cap construction for the C&D landfill. The new pit will start 150 feet south of the canal adjacent to Cub Road and 60 feet west of Pit #L Mining will progress northeast towards Grouse Road at an average depth of 18-20 feet below msl. Mining activities will follow the sequence outlined above for the existing excavation (Pit 43). 2. Describe specific erosion control measures to be installed prior to land disturbing activities and during mining to prevent offsite sedimentation (inchrde specific plans fa -sediment acid et-osion control for mine excavation(s), waste piles, access/mine roads crud process areas), and give a detailed sequence 01' installation and schedule for maintenance of the measures. Locate and label all sediment and erasion control measures on the mine inap(s) and provide typical crass-sectionslcoi7struction details al'eoch measure. Engineering designs and calculations are required to justify the adequacy of any proposed measures. Land disturbing activities in the mining area are accomplished such that all stormwater runoff is directed into cacti mining pit. Drainage into the southern mining pit (Pit #3) drains north where it is pumped into Pit #2. Pit #2 gravity drains into Pit #I . For ultimate discharge from Pit # 1, see the discussion in Section 3.b. of this permit. Once the new pit is started (Pit #4 on Sheet C-3) drainage will be pumped into Pit #2 where if will gravity drain into Pit #I before ultimately discharging into the canal along Cub Road. This will be done to minimize turbidity discharging into the canal along Cub Road. -6- APPLICATION FOR A MINING PERMIT Two surface drainage ditches drain the stockpile area. Sedimentation basins are constructed in each of the two ditches flanking the sides of the stockpile area to treat stormwater and soil drainage. Disturbed areas that are subject to future disturbance will receive temporary seeding if the area remains exposed for more than 30 days. Additional details are shown on Sheet D-1. Completed cut and fall slope areas will be seeded and grassed in accordance with the Vegetation Plan within the Approved Erosion and Sedimcntation Plan provided in Appendix A. 3. a. Will the operation involve washing the material mined, recycling process water, or other waste water handling? Ycs ❑ No X. If yes, briefly describe all such processes including any chemicals to be used. b. Will the operation involve discharging fresh or wastewater from the mine or plant as a point discharge to the waters of the State? Yes ® No ❑. 1 f ties, briefly describe the nature of the discharge and locate all proposed discharge points (along with their method of stabilization) on your mine map(.). All water discharged from Pit #1 gravity drains from Pit #1 and flows west along Cub Road. At the intersection of Cub Road and Bear Road drainage is directed north and discharges from the property at the intersection of Bear Road and Gadwell Road. For more information see Sheet C-lA for the current mine dewatering plan and Sheet C-3A for the proposed dewatering plan. As stated in Section 2, Pit #1 is the only point discharge location regardless of where mining operations are taking place. c. Will any part of the proposed mine excavation(s) extend below the water table? Yes ® No D. If yes, do you intend to dewatcr the excavation(s)? Yes ® No F. If yes, what impact, if any, will mine dewatering have on neighboring wells? Mine dewatering is not anticipated to have an impact on neighboring wells. Estimated maximum withdrawal rate in gallons per day: 1.7 million gallons day_. Locate all existing wells on the mine maps) that lie within 500 feet of the proposed excavation area. Provide data to support any conclusions or statements made, including any monitoring well data, well construction data and current water withdrawal rates. Indicate whether the proposed mine locale is served by a public water system or private wells. There are no water supply wells that lie within 500 feet of the proposed permitted mining area. All groundwater monitoring wells for the C&D landfill are located on the north side of Cub Road approximately 450 feet from the proposed excavation area. The wells are sampled semiannually and copies of the past two groundwater reports for the C&D landfill are located in Appendix B. d. If you answered yes to any of the above questions, provide evidence that you have applied for or obtained the appropriate water quality pemiit(s) {i.c., non -discharge, NPDES, Stormwater, ctc.) from the Division of Water Quality, Water Quality Section. In addition, the applicant is required to register water use with the Division of Water Resources if the operation withdraws more than 10,000 gallons per day and needs a capacity use permit from the Division of Water Resources if the operation lies in a capacity use area and withdraws more than 100,000 gallons per day. A general Stormwater NPDES permit for mining operations has been approved by the N.C. Division of Q Water Quality (Appendix C) and water withdrawal has been registered with the Division of Water ® Resources (Appendix D). The pump operates at 1,200 gallons per minute (gpm) with a maximum daily discharge of 1.7 million gallons per day (MGD). The pump is only operated as needed and day to day ® operations will operate well below the 1.7 MGD threshold. 4. a. Will the operation involve crushing or any other air contaminant emissions'? Yes ❑ No ®. Q -7- APPLICATION FOR A MINING PERMIT If yes, indicate evidence that you have applied for or obtained an air quality permit issued by the Division of Air Quality or local governing body. b. How will dust from stockpiles, haul roads, etc., be controlled? Dust is generated from the operation of heavy equipment, waste and stockpile hauling vehicles tracking mud onto the site, and by wind erosion of unvegetated earth. A water truck is used for dust control on all roadways. Dust conditions are mitigated as necessary at the landfill and borrow pit by dampening of interior . access roads, cleaning of paved public roadways at the site entrance, and stabilizing completed areas with vegetation per the existing Construction Plan for the site. a. A buffer will be required between any mining activity and any mining permit boundary or right-of- way. It may be an unexcavatcd buffer (no excavation, but roadways, berms and erosion & sedimentation control measures may be installed within it), an undisturbed buffer (no disturbance within the buffer whatsoever), or a combination of the two, depending upon the site conditions. Note that all buffers must be located within the mining permit boundaries. How wide a buffer will be maintained between any mining activity and any mining permit boundary or right-of-way at this site`? A minimum buffer of 25 feet is recommended, a]though a wider buffer may be needed depending on site conditions. Show all buffer locations and widths on the mine map(s). As shown on Sheets C-1 and C-3, a 25-foot buffer is maintained between the existing borrow pit and the tree line on the cast side of Pits #1, #2, and #3. A 25-foot buffer is maintained between the southeastern edge of Pit #3 and the woods line south of Grouse Road. The southeastern pit sideslopc of Pit #3 has been completed and will not move any closer towards Grouse Road. The eastern edge of Pit #4 will maintain a 50- foot buffer between the edge of the pit and the wetlands that extend 550 feet from the canal along Grouse Road and run parallel to the haul road. A 15-foot buffer will be maintained on each side of the 30-foot wide haul road (60 feet total) that will separate the current active area (Pit #3) and the proposed mining area (Pit #4). A 25-foot buffer will be maintained between Pit #4 and the drainage ditch that marks the western edge of the proposed permit boundary. A 150-foot buffer will be maintained between the north sides of Pits #1 and #4 and the centerline of the canal along Cub Road. b. A minimum 50 foot wide undisturbed buffer will be required between any land disturbing activities within the mining permit boundaries and any natural watercourses and wetlands unless smaller undisturbed buffers can be justified. Depending on site conditions, a buffer wider than 50 feet may be needed. I -low wide an undisturbed buffer will be maintained between any land disturbing activities within the mining permit boundaries and any natural watercourses and wetlands at this site`? Show all bqf fer locations and widths on the mine map(s). As explained in Section 5a, a 15046ot buffer will be maintained between Pits #1 and 94 and the centerline of the canal along Cub Road to the north, and a 50-foot buffer between mining activities and the limit of the wetlands as shown on Sheets C-1 and C-3. 6. a. Describe methods to prevent landslide or slope instability adjacent to adjoining permit boundaries ® during mining. Minimum 2 horizontal to I vertical slopes or flatter for clayey material and minimum 3 horizontal to l vertical slopes or flatter for sandy material are generally required, unless technical justification can be provided to allow steeper slopes. Due to the sandy nature of the excavated material a free settling slope is maintained on all active excavation © surfaces. Upon completion of excavation the final slopes for the outer slopes will be 3:1 (I+V). All other existing slopes will be in accordance with the previous approved mining permit. After completion of ® excavation for a major portion of an area the final outer face above the water table will be stabilized with APPLICATION FOR A MINING PERMIT vegetative cover. b. Provide a cross-section on the mine map(,) Jbr all fill slopes (berms, wastepiles, overburden disposal areas, etc.), clearly indicating the intendedside slope gradient, installation ofany benches and/or slope drains (vvith .supporting design information) if needed, and the method of final Stabilization. Not Applicable. c. In excavation(s) ofunconsolidated (non -rock) materials, specify the angle of all cut slopes including specifications for benching and sloping. Cross-sections,for all cut .slopes must be provided on the mine map(s). Upon completion of excavation the final slopes for the outer slopes will be 3:1 (14:V). All other existing slopes will be in accordance with the previous approved mining permit. d. In hardrock excavations, specify proposed bench widths and heights in feet. Provide cross -sections of the mine excavation clearly noting the angles of the cut slopes, widths of'all safety benches and mine benches, and the expected maximum depth of the excavation Not Applicable. 7. Describe other methods to betaken during mining to prevent physical hazard to any neighboring dwelling house, public road, public, commercial or industrial building from any mine excavation. Locate all such structures on the mine map if they are ►t,ithin 300 feet of'any proposed excavation. There arc no dwellings, houses, public roads, or public, commercial, or industrial buildings located within 300 feet of the existing and proposed excavation areas. 8. Describe what kind of barricade will be used to prevent inadvertent public access along any high wall area 0 and when it will be implemented. Vegetated earthen berms, appropriate fencing and adequate boulder barriers may be acceptable high wall barricades. A construction detail/cross-section and location of each type cif barricade to he used must he indicated on the mine map(s). The site is located in a relatively remote area of mainland Darc County. The site is bounded on the east by ® U.S. Highway 264 and on the other three sides by the Alligator River National Wildlife Refuge. Access to the area is limited to Link Road and Cub Road. A gate is installed on Link Road at the western end of the S bridge and is locked with a padlock when not in service. A similar gate is installed at the Cub Road entrance. . A gate attendant house is located immediately inside the gate on the southern edge of Cub Road, The entrance is manned by a gate attendant at all times when the facility is open. O Access from the western side of the C&D landfill is unlikely since all adjacent property is in the Wildlife Refuge and the nearest public access to the Refuge (other than Link Road) is approximately 5 miles away. • However, a swinging padlocked gate at the western end of Link Road controls access to the western portions of the site. The gate belongs to the U.S. Fish and Wildlife Service and is locked at all times when not in use to prevent unauthorized access to the Refuge. A 0.75-inch steel cable attached to two 4-inch diameter steel posts cemented into the ground controls access . to the waste disposal area via Cub Road and the excavation service road. The steel cable is padlocked when not in use. The cable posts arc installed at the bridge over the canal adjacent to Cub Road to prevent vehicles from bypassing the cable restriction. The excavation access road to the borrow pit area is chained off when not in use. Moveable construction ® barricades or other warning barriers are installed parallel to the active face unless it is known that the below 0 -9- APPLICATION FOR A MINING PERMIT water slope is no greater than 2:1. 9. Are acid producing minerals or soils present? Yes ❑ No E. If yes, how will acid water pollution from the excavation, stockpiles and waste areas be controlled? Although surface water in the area is generally acidic, the acidity is due to the decomposition of surface organic material. The Albermarlc-Pamlico peninsula usually has a stratified groundwater regime. Subsurface aquifers that are separated from the uppermost groundwater layer by relatively impervious materials are alkaline due to limestone deposits. Any excavations that penetrate the subsurface aquifers can potentially fill with non -acidic water. pl-1 readings taken from the existing borrow pit excavation indicate that the pond resulting from the proposed excavation area will be neutral to alkaline. 10. a. Describe specific plans (including a schedule of implementation) for screening the operation from public view such as maintaining or planting trees, bushes or other vegetation, building berms or other measures. Show the location of all visual screening on the mine map(s) and provide cross - sections through all proposed berms or proposed spacing, sizes and species,for tree plantings. As stated previously, the site is located in a relatively remote area of Dare County. The site is currently shielded on the cast, north, and south by a barrier of natural trees and undergrowth that is on average a minimum of 270 feet thick. These natural tree barriers are on the existing C&D landfill site owned by Dare County and are maintained by the County as a site barrier for the entire C&D landfill property. Beyond the tree barrier the site is buffered and shielded by the Alligator River National Wildlife Refuge on the north, west, and south. Public view of the site is limited along U.S. Highway 264 by the eastern tree line sight barrier except at the Link Road access point. b. Could the operation have a significantly adverse effect on the purposes of a publicly owned park, forest or recreation area? If so, how will such effects (i.e., noise, visibility, etc.) be mitigated'? The existing borrow area has been in operation since 1995 to meet the C&D landfill soil material requirements. Proposed borrow operations are identical to those employed since that time. Consequently, no significant adverse effect on the purposes of a publicly owned park, forest, or recreational area is expected from the proposed borrow pit expansion. In addition to current landfill operations, the site also supports the Dare County Shooting Range and model aircraft flight area. Cleared areas not currently in use for landfill activities are under cultivation along with portions of the U.S. Fish and Wildlife property. Since these same operations have been ongoing since 1995 no adverse effects are anticipated from continuation of the same operations. Current mitigation measures are described below. A water truck mitigates dust on all site roads. The borrow pit operation is buffered from the remainder of the site by the landfill operation and agricultural activities. These activities have been underway since 1995 and are similar to those proposed for future site use. Litter control will be provided by: - Maintaining the smallest usable working face. - Deploying litter fences and potable lifter screens as necessary. - Requiring all waste hauling vehicles entering the site to have in place adequate covers for containment. - Routinely policing the site and U.S. Highway 264 in the vicinity of the site. 11. Will explosives be used? Yes ❑ No N. If yes, specify the types of explosivc(s) and describe what precautions) will be used to prevent physical hazard to persons or neighboring property from flying rocks or excessive air blasts or ground vibrations. Depending on the mine's location to nearby structures, more detailed technical information may be required on the blasting program (such as a third -party blasting study). Locate the nearest offsite occupied structure(s) to the proposed exCavatlon(4) on the mine map and indicate its approximate distance to the proposed excavation. - 10- APPLICATION FOR A MINING PERMIT Not Applicable. 12. Will fuel tanks, solvents, or other chemical reagents be stored on -site? Yes ❑ No M. If yes, describe these materials, how they will be stored and method of containment in case of vpill. Indicate the 10Calti0n(4) of all storage facilities on the mine rnap(s). Not Applicable. D. RECLAMATION PLAN Describe your intended plan for the final reclamation and subsequent use of all affected lands and indicate the sequence and general methods to be used in reclaiming this land. This must include the method of reclamation of settling ponds and/or sediment control basins and the method of restoration or establishment of any permanent drainage channels to a condition minimizing erosion, siltation and other pollution. This information must be illustrated on a reclamation map and must correspond directly with the h?1hrmation provided on the mine map(v). In addition, design information, including typical cross -sections, of'anv permanent channels to be constructed as part of the reclamation plan and the location(,$) of all permanent channels must be indicated on the reclamation map. After closure of the facility, all uses of the property will be limited to activities that will pose no threat to the integrity of the grass cover, cap, monitoring systems, or any other components necessary for the protection of human health or the environment. Unless approved by the Solid Waste Section use of the closed landfill and related mining pits will be limited to recreational and agricultural purposes. The ponds resulting from excavation of the soil materials may be developed into recreational lakes with a parking area and boat access. Because of the high water table at the site the excavations will produce an open ponds approximately 18-20 feet deep. The ponds created can be stocked with indigenous species offish and create a productive freshwater environment unique to mainland Dare County. 2. Is an excavated or impounded body of water to be left as a part of the reclamation? Yes ® No ❑. If yes, illustrate the location of the body(s) of water on the reclamation map and provide a scaled cross-section(S) through the proposed body(s) of water. The minimum water depth must be at least 4 feet, measured from the normal low water table elevation, unless information is provided to indicate that a more shallow water body will be productive and beneficial at this site. Will the body(s) of water be stocked with fish? Yes ® No ❑ If yes, specify species. The created ponds will be approximately 18-20 feet deep and can be stocked with indigenous species of fish. 3. Describe provisions for safety to persons and to adjoining property in all completed excavations in rock including what kind of permanent barricade will be left. Acceptable permanent barricades are appropriate fencing, large boulders placed end -to -end, etc. Construction details and locations of all permanent barricades must be shown 017 the reclamation map. Since access to the site will be through the landfill area, access will be controlled in the same manner as the approved landfill site. 0 0 0 0 APPLICATION FOR A MINING PERMIT 0 4. Indicate the method(s) of reclamation of overburden, refuse, spoil banks or other such on -site mine 0 waste areas, including specifications for benching and sloping. Final cross -sections and locations for such areas must be provided on the reclamation map. Topsoil that is stripped off the borrow pit excavation areas is stockpiled and will be used for final cover at the on -site C&D landfill to support vegetative cover as required and as previously approved by the North Carolina Solid Waste Section. Any material taken from the excavations will be used at the landfill for cover O and fill material or for off -site fill in limited quantities. No spoil banks or mine waste piles are expected to remain after borrow pit operations have ceased. It is expected that all excavated material will be used at the on -site C&D landfill site and associated facilities. a. Describe reclamation of processing facilities, stockpile areas, and on -site roadways. No processing facilities are present, but the stockpile area and haul road will be revegetated at grade according to plans and procedures previously approved by the North Carolina Solid Waste Section for the C&D landfill. b. Will any on -site roadways be left as part of the reclamation? Yes ❑ No Z. If 'es, identify such roadways on the reclamation map and provide details on permanent road and ditch lire Stabilization. The roadway between the existing and proposed excavation areas will be revegated at grade. Describe the method of control of contaminants and disposal of scrap metal, junk machinery, cables, or other such waste products of mining. (Note definition of refuse in The Mining Act of 1971.) No off -site generated waste shall he disposed of on the mine site without prior written approval from the NC Department of Environment and Natural Resources, Land Quality Section and either the Division of Waste Management (DWM) or local governing body. If a disposal permit has been issued by DWM for the site, a copy of said permit must be attached to this application. All temporary and permanent refuse disposal areas must be clearly delineated on the mine rnap(v) and reclamation map, along with a list of items to he disposed in said areas. No scrap metal, junk machinery, cables, or other waste products of mining is anticipated. The mined soil will be utilized for landfill cover on the C&D landfill or offsitc. 7. Describe your plan for revegetation or other surface treatment of'the affected areas. This plan must include recommendations for year-round seeding, including the time of seeding and the amount and type of seed, fertilizer, lime and mulch per acre.

The intent of this permit is to obtain a sedimentation and erosion control plan and permit for the proposed Cell 4 Construction and Demolition Debris Landfill (C&D) expansion. This expansion will consist of an 11.3 acre soil lined cell that will receive construction and demolition debris. The proposed expansion is identical to the previously approved cell number 3 expansion that is currently in operation. The approximate site location is shown on the USGS map provided in Appendix A. A site map of the facility is also included on Sheet C-1 (See Appendix C). Topography within the site boundaries is characterized by flat areas at or near mean sea level. 1.2 Soils The Dare County Soil Survey was used to evaluate the upper subsurface soils within the proposed site boundaries. The information for the Dare County Soil Survey, North Carolina was obtained from the National Resource Conservation Service (NRCS) and is attached in Appendix B. 1.3 Project Description The area of disturbance is 18 acres and includes access roads; canal crossings; filter basins for stormwater management; and silt fence around the perimeter of the proposed cell for added erosion and sedimentation control. The proposed Erosion and Sedimentation Control Measures are identified on C-3 and details are presented on Sheets D-1 and D-2 (See Appendix C). Supporting calculations are provided in the attached Appendix E. The Financial Responsibility/Ownership Form for the project, including a copy of the Property Deed is provided in Appendix D. 1-1 Sea 1 • NICMWr W. Section 2 Planned Erosion and Sedimentation Control Practices The location of the erosion and sedimentation control features described below are shown on the design drawings and details contained in Appendix C. In addition, the North Carolina Erosion and Sediment Control PIanning and Design Manual is referred to in the project specifications. Calculations supporting the design are in Appendix D. The contractor shall be responsible for installing all erosion control devices prior to beginning any land disturbing activities and'shall maintain all control devices until construction is completed and all disturbed areas are stabilized. 2.1 Surface Roughening - Practice 6.03 Any disturbed areas will be lightly roughened by disking just prior to vegetating. All construction slopes 3:1 or steeper will also be roughened. Surface stabilization will be accomplished with vegetation and mulch as specified in the vegetation plan. 2.2 Gravel Construction Entrance - Not Applicable A temporary gravel construction entrance/exit will be not be required, because all construction and landfill operation traffic will enter/exit by the proposed entrance road located off Link Road (Gravel Road) or the haul road located off Cub Road (Gravel Road). 2.3 Temporary Seeding - Practice 6.10 Temporary seeding will be provided as described in Section 5.1 of the Vegetative Plan. 2.4 Permanent Seeding - Practice 6.11 Permanent seeding will be provided as described in Section 5.2 of the Vegetative 2.5 Mulching - Practice 6.14 Mulching will accompany both permanent and temporary seeding at a minimum and will be completed immediately following seeding. 2.6 Silt Fence - Practice 6.62 Silt fence will be installed as shown on Sheet C-3, until permanent vegetation is established. A silt fence detail has been provided on Sheet D-1. 2.7 Filter Basin Filter basins will be installed at the low points of each existing drainage channel Iocated on the east and west sides of the proposed Cell no. 4. These filter basins will be the primary treatment device used to capture and treat sediment laiden runoff.. 2-1 Sect 2 • ESCdoc Section 3 Construction Schedule Erosion and sedimentation control will be completed to address the Dare County Construction and Demolition Debris Landfill Cell No. 4 Expansion construction. 1. Obtain erosion and sediment control permit approval and other applicable permits. 2. Hold preconstruction conference with NCDENR Land Quality Section at least one week prior to starting construction. 3. Notify permitting agency at (252)-946-6481 that approved the erosion and sediment control plan of the date that construction will begin. 4. Flag the limits of construction. 5. Clear the minimum amount of area necessary to install all silt fence as shown on the construction drawings. 6. Install erosion and sedimentation control measures as shown on the construction drawings. 8. Inspect all erosion and sediment control practices weekly and after each significant (1/2 inch or greater) rainfall event. Clean out sediment from silt fence when the depth of sediment reaches half of the allotted depth. Needed repairs will be made immediately. 9. Permanent ground cover shall be established within 15 working days or 90 calendar days after final grade is reached, whichever is shorter. 10. After site is stabilized, remove all temporary erosion control measures. Cm 3-1 Section 4 Inspection and Maintenance Flan Maintenance of the erosion and sedimentation control structures shall be performed throughout the final construction and during site stabilization. The maintenance activities will consist of the following: 1. All erosion and sediment control practices will be checked for stability and opera Lion following every runoff -producing rainfall but at a minimum once per week and fill out NPDES form NCG010000 (Appendix F). Any needed repairs will be made immediately to maintain all practices as designed. 2. ' Sediment will be removed from behind the sediment fence when it reaches a height of 0.5 feet up the fence. The sediment fence will be repaired as necessary to provide adequate storage volume for the next rain event, I Sediment will be removed from filter basins and channels when it reaches 1/2 the design depth and upon completion of the work. Following cleaning activities all disturbed areas will be stabilized. 4. All seeded areas will be fertilized, re -seeded as necessary, and mulched according to specifications in the vegetative plan to maintain a vigorous, dense vegetative cover. 4-1 6"t 4 - Malntalac 0 Section 5 Vegetative Plan 5.1 Temporary Seeding Ground cover shall be established on exposed slopes within 21 calendar days following completion of any phase of grading. Temporary seeding shall be performed in accordance with the requirements of the North Carolina Erosion and Sediment Control Planning and Design Manual and as shown on the drawings. 5.2 Permanent Seeding Areas to be stabilized with permanent vegetation must be seeded or planted within 15 working days or 90 calendar days after final grade is reached, unless temporary stabilization is applied. Permanent seeding shall be performed in accordance with the requirements of the North Carolina Erosion and Sediment Control Planning and Design Manual and as shown on the drawings. Apply temporary erosion control matting over mulched areas on sloped surfaces greater than 4:1. 5-1 sed 5 • Vefj'd c Section 6 Construction Specifications and Details The erosion and sedimentation control measures will be constructed in accordance with the erosion and sedimentation control details in the Project Plans and Specifications and the North Carolina Erosion and Sedimentation Control Planning and Design Manual. These Specifications and Details are attached as follows: Details 6.03 -- Surface Roughening 6.10 - Temporary Seeding 6.11 - Permanent Seeding 6.14 - Mulching 6.62. - Sediment Fence saw 0 •9pm.duc 6-1 Practice Standards and Specifications Definition Roughening a bare soil surface with horizontal grooves running across the slope, stair stepping, or tracking with construction equipment. Purpose 'fo aid the establishment of vegetative cover from seed, to reduce runoff velocity and increase infiltration, and to reduce erosion and provide for sediment trapping. Conditions Where All construction slopes require surface roughening to facilitate stabilization Practice Applies with vegetation, particularly slopes steeper than 3,1. Planning Rough slope surfaces are preferred because they aid the establishment of vegetation, improve water infiltration, and decrease runuff velocity. Graded Considerations areas with smooth, hard surfaces may be initially attractive, but such surfaces increase the potential for erosion. A rough, loose soil surface gives a mulching effect that protects lime, fertilizer, and seed. Nicks in the surface are cooler and provide more favorable moisture conditions than hard, smooth surfaces; this aids seed germination. Figure 6.03a Bulldozer treads create grooves perpondicular to the slope. The slope face should not be back -bladed during the final grading operation (source: Va SWCC). 'there are different methods for achieving a roughened soil surface on a slope, and the selection of an appropriate method depends upon the type of slope. Roughening methods include stair -step grading, grooving (Figure 6.03a), and tracking. factors to be considered in choosing a method are slope steepness, mowing requirements, and whether the slope is formed by cutting or filling. r 6.03.1 0 0 Design Criteria No formal design is required. Construction CUT SLOPE ROUGHENING FOR AREAS NOT TO BE MOWED Specifications stair -step grade or groove cut slopes with a gradient steeper than 3:1 (Figures p 6.03b and 6.03c). 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. Make the vertical cut distance less than the horizontal distance, and slightly slope the horizontal position of the "step" in toward the vertical wall. Do not make individual vertical cuts more than 2 feet in soft materials or more than 3 feet in rocky materials. 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. FILL SLOPE ROUGHENING FOR AREAS NOT TO BE MOWED 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, CUTS, FILLS, AND GRADED AREAS THAT WILL BE MOWED Make mowed slopes no steeper than 3:1. 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, Make grooves, formed by such implements, close together (less than 10 inches) and not less than 1 inch deep. Excessive roughness is undesirable where mowing is planned. ROUGHENING WITH TRACICED MACIUNFRV 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. Operate tracked machinery up and down the slope to leave horizontal depressions in the soil. Do not back -blade during the final grading operation. 6.03.2 H Debris from slope above is caught by steps.

Purpose To temporarily stabilize denuded areas that will not be brought to final grade for a period of more than 21 calendar days, Temporary seeding controls runoff and erosion until permanent vegetation or other erosion control measures can be established. In addition, it provides residue for soil protection and seedbed preparation, and reduces problems of mud and dust production from bare soil surfaces during construction. Conditions Where On any cleared, unvegetated, or sparsely vegetated soil surface where Practice Applies vegetative cover is needed for less than I year, Applications of this practice pp include diversions, dams, temporary sediment basins, temporary road banks, and topsoil stockpiles. Planning Annual plants, which sprout and grow rapidly and survive for only one season, Considerations are suitable for establishing initial or temporary vegetative cover. Temporary seeding preserves the integrity of earthen sediment control structures such as dikes, diversions, and the banks of dams and sediment basins. It can also reduce the amount of maintenance associated with these devices. For example, the frequency of sediment basin cleanouts will be reduced if watershed areas, outside the active construction zone, are stabilized. Proper seedbed preparation, selection of appropriate species, and use of quality seed are as important in this Practice as in Practice 6.11, Permanent Seeding Failure to follow established guidelines and recommendations carefully may result in an inadequate or short-lived stand of vegetation that will not control erosion. Temporary seeding provides protection for no more than 1 year, during which time permanent stabilization should be initiated. Specifications Complete grading before preparing seedbeds, and install all necessary erosion control practices such as, dikes, waterways, and basins. Minimize steep slopes because they make seedbed preparation difficult and increase the erosion hazard. If soils become compacted during grading, loosen them to a depth of 6-8 inches using a ripper, harrow, or chisel plow. SEEDBED PREPARATION Good seedbed preparation is essential to successful plant establishment. A good seedbed is well -pulverized, loose, and uniform. Where hydroseeding methods are used, the surface may be left with a more irregular surface of large clods and stones. Liming—Applylime according to soil test recommendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone at the Rev. 6)" 6.10.11 0 6.10.2 rate of 1 to 1 112 tons/acre on coarse -textured soils and 2-3 tons/acre on fine - textured soils is usually sufficient. Apply liinestone unifomily and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed. Fertilizer —Base application rates on soil tests. When these are not possible, apply a 10-10-10 grade fertilizer at 700-1,000 lb/acre, Both fertilizer and lime should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more than 30 minutes before application. Surface roughening —If recent tillage operations have resulted in a loose surface, additional roughening may not be required, except to break up large clods. If rainfall causes the surface to become sealed or crusted, loosen it just prior to seeding by disking, raking, harrowing, or other suitable methods. Groove or furrow slopes steeper than 3:1 on the contour before seeding (Practice 6.03, Surface Roughening). PLANT SELE"ION Select an appropriate species or species mixture from Table 6.1 Oa for seeding in late winter and early spring, Table 6.1 Ob for summer, and Table 6.10c for fall. In the Mountains, December and January seedings have poor chances of success. When it is necessary to plant at these times, use recommendations for fall and a securely tacked mulch. SEEDING Evenly apply seed using a cyclone seeder (broadcast), drill, culfipaclker seeder, or hydroseeder. Use seeding rates given in Tables 6.10a-6.10c. Broadcast seeding and hydroseeding are appropriate for steep slopes where equipment cannot be driven. Hand broadcasting is not recommended because of the difficulty in achieving a uniform distribution. Small grains should be planted no more than I inch, deep, and grasses and legumes no more than 112 inch. Broadcast seed must be covered by raking or chain dragging, and then lightly firmed with a roller or cultipacker. Hydroseeded mixtures should include a wood fiber (cellulose) mulch. - MULCHING The use of an appropriate mulch will help ensure establishment under normal conditions, and is essential to seeding success under harsh site conditions (Practice 6.14, Mulching). Harsh site conditions include: • seeding in fall for winter cover (wood fiber mulches are not considered adequate for this use), • slopes steeper than 3:1, • excessively hot or dry weather, adverse soils (shallow, rocky, or high in clay or sand), and • areas receiving concentrated flow_ If the area to be mulched is subject to concentrated waterflow, as in channels, anchor mulch with netting (Practice 6.14, Mulching). Practice Standards and Specifications Maintenance Reseed and mulch areas where seedling emergence is poor, or where erosion occurs, as soon as possible. Do not mow. Protect from traffic as much as possible.

Introduction Duringthe initialphase of all land disturbing projects, theprotective layer, either natural or man-made, is removed from the earth's surface. As the protective layer is removed, the resulting bare areas are exposed to the natural forces of rainfall, freezing, thawing, and wind, The result is soil erosion that leads to sediment pollution of North Carolina streams, rivers, lakes, and estuaries. This design manual presents many alternative strategics for preventing erosion and reducing sediment loss during the construction process. Establishment of protective vegetative cover during the construction project, however, is the crucial step in achieving soil stabilization, controlling soil erosion, and preventing sedimentation ofwaterways. Without asufficient amountof root mat and leaf cover to protect and hold the soil in place, large volumes of soil will be lostand waterways will be degraded long afterprojects are considered complete. Sections of this practice standard address many of these various situations and set forth selection criteria for the appropriate cover based on purpose and adaptability. Some sediment and erosion control practices recommended in earlier editions of the manual may no longer be applicable. For example, many popular and commonly used seed and plant varieties have been identified as invasive. Invasive plants are defined as species that aggressively compete with, and displace, locally adapted native plant communities. In select cases where no practical alternative is available, these plants may be considered on a limited basis for soil stahilization, understanding that the goal is to eliminate the use of all invasive plants in favor of non-invasive native and/or introduced species that will provide an equally acceptable vegetative cover. Where there is no alternative to the use of invasive species, measures need to be incorporated in the installation and maintenance of these plants to limit their impacts. Rev. 5/08 6.11.1 0 It is imp eralive that disturbed soils be total lyprotected from erosion and sediment loss during construction and before a project is considered complete and acceptable. Installing appropriate vegetation in an immediate and timely fashion is the optimal means of achieving this stabilization, Vegetative specifications for most exposed soil conditions across North Carolina are provided in this section of the manual. It should be noted however, that no two sites in the State are exactly alike; therefore the protective vegetative cover for individual sites should be carefully selected. Each requires its own investigation, analysis, design and vegetative prescription as set forth in this section of the manual. This practice standard describes three stages of vegetative cover; immediate, primary and long term. Effective and acceptable stabilization can be provided only when the optimum combination of immediate, primary, and long term vegetative practices are applied. The vegetative measures presented in this chapter include application of seed, sad and sprigs. Use of field and container grown plants are not addressed in this manual. Planting of these types of vegetation is typically at spacing and intervals that will not provide the required protective cover. however, the design professional is encowaged to utilize these larger plants to compliment the required protective cover, particularly where these types of plants will provide seed for continued long term cover and wildlife habitat. PLANNING CONSIDERATIONS SOILS Test and analyze the type(s) and quality of the existing soils on a site, their pIt ranges, and their nutrient levels. Taking soil samples from the different areas of the project site and having them tested at a state or independent lab will provide a baseline for determining the pH modifiers and additional nutrients required for the selected plant varieties. Disturbed conditions on a site may produce a variety of soil communities. Nutrient and pH levels in deeply cut soils will be quite different from those soils found on the original surface. When sites are highly disturbed through mechanical means such as grading, the soils become mixed together in many different ratios. These areas should be identified and tested. Results from soil tests will usually include recommended application rates of soil modifiers such as lime and fertilizer for the selected plant species in the particular soils. Application rates will be itemized in the report. The texture of the soil on a site, which is the proportion of sand, silt, and clay in the soil, is an important physical indicator of the site's ability to support vegetation. In heavy clay soils amendments may be necessary to provide an adequately drained planting medium. Conversely, in extremely sandy soils, amendments may be required to provide for moisture and nutrient retention. 6.11.2 Rev. 5108 Practice Standards and Specifications Soil tests will indicate the texture of the given soil but will not provide recommendations for amendments that will improve the soil texture. Generally, the addition of organic materials will improve the porosity of heavy clay soils and improve the water holding capacity of extremely sandy soils. On sites where these different soil conditions exist, it is recommended that a design professional with experience in soil modification be employed to recommend the proper amendments. For more information visit the NCDA Agronomic Services Soil Testing web page http://www.agr.state.nc.us/agronoinic/sthome.htrn SOIL PREPARATION Proper soil preparation is necessary for successful seed germination and root establishment. it is also necessary for establishment of rooted sprigs, sod and woody plants. Heavily compacted soils prevent air, nutrients and moisture from reaching roots thereby retarding or preventing plant growth. The success of site stabilization and reduction of future maintenance are dependent on an adequately prepared soil bed. Following are the requirements for preparation of areas to be vegetated by grassing, sprigging, sodding, and/or planting of woody plants: General Requirements: • Preparation for primary/permanent stabilization shall not begin until all construction and utility work within the preparation area is complete. However, it may be necessary to prepare for nurse crops prior to completion of construction and installation of utilities. • A North Carolina Department of Agriculture Soils Test (or equal) shall he obtained for all areas to be seeded, sprigged, sodded or planted. Recommended fertilizer and pll adjusting products shall be incorporated into the prepared areas and back -fill material per the test. • All areas to be seeded or planted shall be tilled or ripped to a depth specified on the approved plans, construction sequence and/or construction bid list. Ripping consists of creating fissures in a criss-cross pattern over the entire surface area, utilizing an implement that will not glaze the side walls of the fissures. Site preparation that does not comply with these documents shall not be acceptable. The depth of soil preparation may be established as a range based on the approval of the reviewing state or local agency. Once tilled or ripped according to the approved plan, all areas are to be returned to the approved final grade. pH modifiers and/or other soil amendments specified in the soil tests can be added during the soil preparation procedure or as described below. • All stones larger than three (3) inches on any side, sticks, roots, and other extraneous materials that surface during the bed preparation shall be removed. Rev. 5108 6.11.3 0 Areas to be Seeded: • Till or disc the prepared areas to be seeded to a minimum depth of four (4) inches. Remove stones larger than three (3) inches on any side, sticks; roots and otber extraneous materials that surface. If not incorporated during the soil preparation process, add pH modifier and fertilizers at the rate specified in the soil test report. • Re -compact the area utilizing a cultipacker roller. The finished grade shall be a smooth even soil surface with a loose, uniformly fine texture. All ridges and depressions shall be removed and filled to provide the approved surface drainage. Seeding of graded areas is to be done immediately after finished grades are obtained and seedbed preparation is completed. Areas to be Sprigged, Sodded, and/or Planted: • At the time of planting till or disc the prepared areas to a depth of four (4) to six (6) inches below the approved finished grade. Remove all stones larger than three (3) inches on any side, sticks, roots and other extraneous materials that surface. If not incorporated in the ripping process, add pH modifier, fertilizer, and other recommended soil amendments. • Re -compact the area utilizing a cultipacker roller and prepare final grades as described above. install sprigs, sod and plants as directed immediately after fine grading is complete.. Mulch, mat and/or tack as specified. VEGETATION Availability of seed and plant materials is an important consideration of any construction stabilization effort. -Throughout North Carolina, climate, economics, construction schedule delays and accelerations, and other factors present diffictilt challenges in specifying the different vegetation needed for site stabilization. To help resolve this issue, vegetative stabilization requires consideration in three categories: ■ Immediate Stabilization —nurse crop varieties (Note: temporary mulching may be utilized for immediate stabilization if outlined on the approved plans and construction sequence.) • Primary Stabilization —plant varieties providing cover up to 3 years with a specified maintenance program • LongTerm Stabilization — plant varieties providing protective cover with maintenance levels selected by the owner An adequate job in one of these areas does not guarantee success in the later phases. Horticultural maintenance must be included in the plans. Immediate vegetative cover will always require additional fertilization, soil amendments, soil tests, overseeding and/or other horticultural maintenance until primary vegetative cover is established. 6.11.4 Rev. 5108 Rev. 5/08 Practice Standards and Specifications Where provisions are made for regular maintenance, primary vegetative cover may be the end result. An example of primary vegetative cover being acceptable as an end use would be lawns in residential and commercial developments that are established, monitored and complimented with regular and approved horticultural maintenance practices. (See Example 6.1 l .a.) In projects where continual maintenance will not be provided or scheduled following the primary stabilization of a project, long-term stabilization will be necessary, Maintenance of initial and long-term stabilization can cease only after the long-term cover has established and hardened to local climatic conditions. Maintenance of long-term vegetation must be included in the project construction sequence and on the approved plans. Examples of areas suitable for long term vegetation include roadsides, reforestation areas, restored flood plains, restored riparian areas, phased closing of landfills, and mining reclamation, Complete stabilization requires using at least two, and most times, all three vegetative phases. The design professional mustclearly communicate thispoint in their specifications, construction sequence, and in direct communications to owners and installers. The charts in tables 6.1 La through 6.1 Ld provide information to assist the design professional in this task. The tables are not inclusive and are presented only as alternatives. The professional is expected and required to provide design and specifications that combine the information in the manual with knowledge of the particular sites and their constraints. pH AND NUTRIENT AMENDMENT'S Determining the nutrients that enable seed and container plants to grow, flourish, and become established after planting are critical elements of the design and stabilization process. The soils tests previously described will provide a recipe for amendments based on particular plants and particular soils. The test results will recomnrcnd the amounts of base eiements (nitrogen, phosphorous, potassium), pH modifiers and other trace elements that should to be added to the soil for selected species of seeds and plants. The acid/base characteristic of the soil is a primary component of soil fertility. If the soil acidity is not in the proper range, other nutrients will be ineffective, resulting in less productive plant growth. Most plants grow best in a pH range of 6.5 — 7.0 (slightly acidic to neutral). The soil tests will recommend the specific amendments and application rates required to achieve this range. These amendments must be incorporated into the soil (not applied on the surface) to be effective. (See the General Requirements for soil preparation specifications and timing for incorporation of soil amendments.) The base elements are easily found in bulk quantities. Lime can also be obtained in large quantities. They all must be thoroughly incorporated into the soil through appropriate mechanical means. Ground surface applications without proper soil mixing will result in poor results. In addition to the base -fertilizers, other trace elements are needed to produce healthy and vigorous growth. These include but may not be limited to sulfur, manganese, zinc, boron, chlorine and molybdenum. If not already included with bulk mixes of the base elements, they can be obtained from commercial suppliers. 6.11.5 0 Provisions for soils test during and/or after initial grading is complete shall be included on the approved plan, in the approved construction sequence, and on the bid item list utilized for the project. If you did not obtain a soil test, - Follow these recommendations for all grasses except centipedegrass. 1. Apply 75 pounds of ground limestone per 1,000 sq. ft. 2. Apply a starter type fertilizer (one that is high in phosphorus) based on the type of grass and planting method. Fertilizer bags have a three -number system indicating the primary nutrients, such as 8-8-8 or 5-10-10. These numbers denote the N-P-K ratio —the percentage of each nutrient in a fertilizer, The percentages are always noted in the following order: N Nitrogen for green color and growth. P,.OS Phosphorus for good establishment and rooting. K,O Potassium to enhance pest and environmental stress tolerance. Some common examples of starter type fertilizers required for a 1,000 sq. ft, area include 40 pounds of 5-10-10, 20 pounds of 10-20-20, or 16 pounds of 18-24-6. For sandy soils, typical to coastal plain and sandhills of North Carolina, fertilizer rates should be increased by 20 percent. Where available, it is recommended that the .design professional specify organic compounds that meet the fertilization requirements, pH and other element requirements. Initial studies have indicated that these compounds have a more positive effect on the environment than some of the synthetic compounds used to manufacture inorganic fertilizers. These materials are readily available in the commercial trade as well as found in recycled yard waste debris, sewerage sludge, lime -stabilized sludge and animal manures. Materials proposed for use must be industry certified and/or privately tested and certified to be acceptable for proposed areas of use and application prior to approval. MULCHES AND TACKING AGENTS Mulches and tacking agents may be required or necessary to protect a seedbed's disturbed surface until the seed can germinate and provide the required protection from erosion. Selection of the materials used in this application should be based on their ability to hold moisture in the soil, as well as protect exposed soil from rainfall, storm water runoff, and wind. The availability of the selected material and the means to apply it are critical factors to consider when planning for the stabilization of any disturbed area. The mulch must cover a minimum of eighty (80) percent of the soil surface and mustbe secured by a tacking agent, crimping, or protective biodegradable netting. Netting that incorporates plastic mesb and/or plastic twine should not be used in wetlands, riparian buffers or iioodp3ains due to the potential of small animal mortality. See Section 6.14 for detailed specifications and product applications. SOIL BLANKETS Soil blankets can be an acceptable and effective method of temporary sediment and erosion control in lieu of nurse crops. See Section 6.17 of the manual For descriptions of this product and how it can be used in conjunction with this section. In absence of mulches and tracking agents other means of protection may be necessary and required. 6.n.6 Rev. 5108 0 0 0 0 0 0 0 Practice Standards and Specifications PROTECTIVE MATTING Protective matting consists of an impervious cover secured to the soil surface in lieu of vegetative cover. It is used to protect and stabilize the surface where the process of seeding or planting forms ofvegetation may cause more erosion and off -site sedimentation than application of the mat. It is also used where a disturbed area is intended to lay fallow for a period of time before additional construction or land disturbance takes place. if a pervious matting is selected, a combination of vegetation and matting is required. Seeds can be applied prior to installation of the matting only after proper seedbed preparation has been provided. Also, live stakes, dormant sprigs, and other vegetation forms can be inserted in the perviuus matting once it has been installed. Pre - seeded pervious matting may be used for quicker root establishment and stabilization only if certified dating and germination guarantees are provided. The reviewing agency must approve all pre -seeded matting on site prior to installation. Malting that incorporates plastic mesh and/or plastic twine should not be used in wetlands, riparian buffers or floodplains due to the potential of small animal mortality. See Section 6.17 for detailed specifications and recommended product applications. STABILIZATION IN WETLANDS, RIPARIAN BUFFERS, AND FLOODPLAINS Land disturbing activity involving streams, wetlands or other waterbodies may also require permitting by the U.S. Amoy Corps of Engineers or the N.C. Division of Water Quality. Approval of an erosion and sedimentation control plan is conditioned upon the applicant's compliance with federal and State water quality laws, regulations, and rules. Additionally, a draft plan should be disapproved if implementation of the plan would result in a violation of rules adopted by the Environmental Management Commission to protect riparian buffers along surface waters. Care should be taken in selecting vegetative stabilization of wetlands and riparian buffers to comply with permitting requirements of other agencies, as well as provide adequate ground cover. Planning Considerations for Land Disturbing Activities Within Wetland, Riparian, and Floodplain Areas Wetlands, riparian areas, floodplains, and/or terrestrial areas between streams and uplands, serve to buffer surface water and provide habitat for aquatic and terrestrial flora and fauna. When cleared and disturbed, these sensitive areas are difficult to protect. Because of their proximity to watercourses, relatively high ground water tables, and flooding potential, detailed analysis and design is necessary to determine the appropriate erosion control measures during construction. Determining the appropriate and most expeditious means of permanent vegetative stabilization in these areas requires equally detailed analysis and design. The following considerations for erosion control and stabilization should be taken into account during the design phase of the land disturbing project where sensitive areas are involved: • Obtain soil tests to determine the soil type, pH, texture and available nutrients. • Based on the soil tests provide a schedule of nutrients and other soil amendments that will be required. Rev. 5/08 6.11.7 0 • Select a seeding mix of non-invasive species that will provide immediate stabilization (a short-term environment that will support and compliment permanent vegetative stabilization) and include a selective native species mix that will eventually provide a permanent cover (a long-term environment that, with minimal maintenance, will provide adequate root and leaf cover). Invasive species are to be avoided. If native species and introduced non- invasive seed sources are not available, protective matting that will hold and foster the development of native cover from adjacent seed sources should be used. Continuous maintenance must be employed until the selected species have matured and are no longer susceptible to competition from invasive plants. If no alternative to the use of invasive seeds and plants is available, invasives approved on the plans may be utilized only with strict containment measures outlined in detail on the plans, in the construction sequence and in the maintenance specifications. • Aquickly germinating nurse crop of non-invasive, non-competitive annual grass species can be used along with native seeding and/or matting. 'these temporary systems should be planted at minimal density so that they do not inhibit the growth and establishment of the permanent, native species. (See the plant chart in Table 6,1 La for recommended native and nurse crop species,) • Seedbed preparation is key to successful establishment ofseeds. Particular care should be taken, however, when working in wetlands, riparian areas, or floodplains due to their sensitive nature. Careful consideration should be given to the types and placement of large equipment working in these areas. This process must be outlined in detail on the plan's construction sequence. • Installation techniques vary and should be planned for accordingly. • A maintenance plan must be established for optimal plant establishment, submitted with the plans and included in the bid list for the project. Like all construction sites, wetlands, riparian areas, and floodplains will vary widely in physical makeup across North Carolina. Different conditions will dictate specific treatment, design and plant selection within the Mountains, Piedmont, and Coastal Plain regions. Soil tests, seedbed preparation, mulching, matting, and maintenance will be critical for successful vegetative establishment and long-term protection of these environmentally sensitive areas. Unavoidable impacts to these areas during land disturbing activities need to be addressed in detail on the plan sheets and construction sequence. 6.11.8 Rev. 5108 Practice Standards and Specifications ]Native Seed and Plant Selection for Stabilization of Wetlands, Riparian Areas, and Floodplains Upon the completion of the land disturbing activity, vegetative cover must be established on all areas not stabilized by other means. If work in these areas stops for more than 15 working days, temporary vegetative cover and/ or matting must be applied to all disturbed areas. The goal is to protect these areas from erosion and to prevent sedimentation of adjacent streams, wetlands, lakes, and other water bodies, Planning considerations for wetlands, riparian areas and floodplains will require additional research, detail and specifications. Native grasses are usually required as a condition of a 401 Water Quality Certification or a trout buffer variance. Native vegetative species are plant species that naturally occur in the region in which they evolved. These plants are adapted to local soil types and climatic variations. Because most native species do not germinate and establish as readily as some introduced species, it is necessary to provide a non-native nurse crop or matting to stabilize the soil until the native crop can become established as the dominant cover. Once established, the native plants will produce an extensive root structure that, if properly maintained, will stabilize soils and reduce erosive forces of rainfall and overland stormwater flow. Many of these plants also possess characteristics that, when established, allow them not only to survive, but also to thrive under local conditions. Seeding a mixture of perennial native grasses, rushes, and sedges is a way to establish permanent ground cover within wetlands, riparian areas and floodplains. The use of propagated plants is another method of reestablishing natives in these environments. Selecting a seed mixture and/or propagated plants of different species with complimentary characteristics will provide vegetation to fill select niches on sites with varying physical conditions. The design professional should note that because most native species do not germinate and establish as readily as some introduced species, it is necessary to provide a non-native nurse crop or matting to stabilize the soil until the native crop can become established as the dominant cover. For additional information about acceptable nurse crop varieties, consult the planting list in Appendix 8.02, local seed and plant suppliers, the North Carolina Cooperative Extension Service or a qualified design professional to assure the proper selection and plant mix. Rev. 5108 6.11.9 a Permanent native seed species within the seed mixture should be selected based on natural occurrence of each species in the project site area. Climate, soils, topography, and aspect are major factors affecting the suitability ofplants for a particular site and these factors vary widely across North Carolina, with the most significant contrasts occurring among the three major physiographic regions of the state -- Mountains, Piedmont, and Coastal Plain. Sub -regions of the state should also be considered. For example, the Triassic Basin in the Piedmont region may have characteristics that call for special soil treatment, limited plant selection, and special maintenance. Even within the riparian area, there may be need for different species depending on site conditions (i.e., dry saudy'alluvial ftoodplains with wet pockets). Therefore, thoughtful planning is required when selecting species for individual sites in order to maximize successful vegetation establishment, , Native seed and plant species are included on the plant list in Appendix 8.02 of this manual. The design professional should note that regardless of the benefits and advantages of native seeds and plants, there are potential issues if proper planning, installation and maintenance do not occur. "These may include, • Potential for erosion or washout during the establishment stage; • Seasonal limitation on suitable seeding dates and availability of seed and plants; • Adaptability of species at specific sites; • Availability of water and appropriate temperatures during germination and early growth; and • Lack of maintenance to control invasive plants and undesirable competition. PLANTING Seed —Prepare the seed bed as described above in soil preparation. Apply seed at rates specified on the plans, and/or as recommended in Tables 6.11a-c of this manual, with a cyclone seeder, prop type spreader, drill, or hydroseeder on and/or into the prepared bed. Incorporate the seed into the seed bed as specified. Provide finished grades as specified on the approved plan and carefully culti-pack the seedbed as terrain allows. If terrain does not allow for the use of a cultipacker, the approved plans and construction sequence must provide an alternative method of lightly compacting the soil. Mulch immediately. • Sprigs and Sod — Install onto the prepared seed bed per the most current guidance in Carolina Lawns, NCSU Extension BulletinAGr-69, or Practice 6.12 .Sodding. 6.11.10 Rev.

See Practice 6.13 Trees, Shrubs, Imes, and Ground Covers, MAINTENANCE The absence of or an incomplete landscape management specification Lind/ or complete maintenance schedule shall constitute grounds for disapproval of the plans. Proper maintenance is critical for the continued stabilization once vegetative cover is established. Although maintenance strategies for different sites may be similar, no two construction sites in North Carolina have been or will be able to be controlled or protected in identical ways. Variations in climate, topography, soils, available moisture, size and many other conditions will dictate the maintenance methodology to be used. A detailed schedule of maintenance will be required on the plans. This schedule will illustrate how the initial planting will be maintained to assure immediate, short term and permanent protection. The schedule will address topics such as appropriate irrigation of plants during the early establishment phase, drought conditions, excessive rainfall, mulch replacement, supplemental seeding, supplemental soils tests, application of nutrients and amendrncrrts, control of competitive and invasive species, disease and insect control, and corrective maintenance, measures to address failure of vegetation to become established. Contractual responsibility for maintenance after initial establishment of vegetative cover will be provided on the plans, in the construction sequence and on the bid list for the project. Maintenance bonds and/or warranty guarantee may be required of the responsible party, especially for areas in or adjacent to environmentally sensitive sites such as wetlands, riparian buffers, floodplains, and waters of the State. See Example 6.11a for a sample maintenance specification and a minimum maintenance check list that shall be provided on all plans.

SEEDING RECOMMENDATIONS The following tables list herbaceous plants recommended for use as nurse crops for immediate stabilization and primary crops for initial and long-term stabilization. Nurse crops are expected to develop in two to five weeks and, with adequate maintenance, be an effective method of soil stabilization fur a period of six months to one year. Nurse crops are not effective as primary long-term cover, however if properly maintained they can be an adequate cover and protection for the development of primary crops. The goal for a primary crop is for it to develop over a three-week to one-year period and be effective up to three years with a well-defined maintenance program. The long-term goal for a primary crop is the initial step toward a sustainable protective cover without the need of maintenance. Where the primary crop is intended for a managed lawn and landscape aesthetics, the effective period can be extended by a more intense maintenance program. Where native species are utilized and become established during the planned maintenance program, a permanent cover that will support future succession species should exist and require little or no additional maintenance or management. In uses of both nurse and primary crops, the development periods listed on the tables are optimal based on normal climatic conditions for the planting dates listed. The sediment and erosion control maintenance program must recognize that optimum temperatures and rainfall are the exception rather than the rule. The design professional needs to provide flexibility in the stabilization plan to address the potential ranges of temperature and moisture conditions we experience in North Carolina. Rev. 5M Practice Statzdardv and Specifications Information is provided for seeding rates, optimum planting dates in the state's three regions, sun and shade tolerance, invasive characteristics, compatibility in wetlands and riparian buffers, and installation maintenance considerations. By going through the lists the design professional can select the nurse and primary seed varieties and maintenance characteristics they feel are best suited for their site conditions, vegetation management expertise and maintenance capabilities. To use the information in the seeding charts the plan preparer must: • Determine what nurse crop best fits their site, soil conditions, and permanent seed mix. • Obtain soil tests for all areas to be seeded, • Know the site's region: mountains, piedmont, or coastal plain. • Know if the areas to be seeded are sunny, part shade, or full shade. • Know if the areas are well or poorly drained. • Know if wetlands or riparian buffers are included in the areas to be seeded. • Know if a chosen crop is invasive and ifso, what potential impacts it will have on the site and adjacent properties. With this knowledge the plan preparation may proceed utilizing the charts provided to provide the several seed mixes that will be applicable to the different areas requiring stabilization.

In addition to the native species mix, additional nurse crop species must be included to provide immediate stabilization and an adequate ground cover. Rev. 5108 6.11.19 0 Example 6.11.a GUIDELINES FOR WRITING MINIMUM LANDSCAPE MANAGEMENT SFECIFICATTON5 Following is an outline that demonstrates what should be included in specifications that will insure the long term stabilization of disturbed sites in North Carolina.. As noted before in this manual, each construction site in the state is unique and has features that will require special provisions for revegetation and stabilization. The outline provided below cannot address these individual sites. It is the responsibility of the design professional and the financially responsible party to see that the specifications are, edited to fit their site and to assure that permanent stabilization is achieved. General Provisions A. Intent: 1. These specifications are prepared with the intent of promoting outstanding performance in long- term stabilization. They are to be used as guidelines in establishing sediment control and vegetative standards for the sites. Final technical decisions such as herbicides, fertilizer ratios, times of application and schedules are to be determined by the Contractor, who has the responsibility to obtain soil test and to manage the vegetation to achieve the desired results. The maintenance specifications must address maintenance for sediment and erosion control vegetation during construction and for permanent/long-terns stabilization. B. Description of Work: i. Perform all work necessary and required for the (insert period of contract) maintenance of the project as indicated on the drawings, in the project manual, and specified herein, 2. Licensing: a) Contractor shall provide verification of current, applicable pesticide applicator licensing for each applicator that will handle pesticides on the contracted sites. 3. Contract Administration a) Staffing: The Contractor shall provide adequate staffing, with the appropriate expertise, to perform all required work. b) Monthly Site Review meetings will be held. Attendees will include the Contractor's Project Manager and Site Foreman and the property manager or other representative designated by the financially responsible party. Result of site reviews will be documented and circulated to the attendees and the owner by the contractor. c) The Contractor will communicate with the proper person on a monthly basis to summarize work performed and immediately notify the project manager of any failure of the site to remain stabilized. II. Materials A. Soil Additives: Additives are to be applied per soils test taken prior to, during and after construction_ (Use this section to provide the types and quantities of fertilizers, lime, and other soil amendments called for in the soils report. Include all soils test reports in the specifications document. This narrative or list should Include quantities, rates, mixes, organic information, Manufacturer, sources, and other information suggested in the soils test.) 6.11.20 Rev. 5108 Practice Standards and SpecOeation,s A. Pesticides: 1. F,stablish an Integrated Pest Management (iPM) program for the site that relies on targeted insect and disease control coupled with sound stabilization management and water management practices. 2. These specifications do not include pesticide treatments for infestations of Southern Pine Rectle, Gypsy Moth, or Fire Ants. The contractor shall notify the Owner if these pests are observed on site. 3. All pesticides shall be applied by a North Carolina licensed applicator in accordance with all State and Federal regulations and per manufacturer's recommendations. B. Mulches: Mulch for areas not subject to erosion and over wash by storm water should be called out in this section addressing its maintenance, replacement, removal and conversion to other uses. Those subject to erosion and over wash by storm water must be addressed on the plans and in the calculations. 111. Execution A. General: 1. Good long term stabilization is based on the proper maintenance, management and balance of nutrients, soil moisture and general cultural practices. It is recognized that Fewer fungicide and pesticide treatments as well as lower fertility rates are required with a well managed, balanced landscape. The following section is meant to promote this balance and therefore do not highlight specific quantitative standards. (Quantitative standards should be addressed as site specific by the design professional in conjunction with the owner and contractor.) Calendar references are general and are to be used only as a guide. Weather and soil conditions that are most appropriate for a given process, procedure and/or area of the state shall be the determining factor in scheduling work. B. Soil Tests: 1. After the soil test prior to stabilization, tests shall be made yearly in the fail to determine the required soil additives for all stahilimd areas. If known nitrogen requirements are not specified by previous test, they need to be determined by the subsequent soils test and the proper applications made. Fertilizer ratios may be determined through analysis of the soil tests coupled with the contractor's experience and knowledge of the site. C. Mowing 1. Mowing for maintained turf/lawns a. Mow areas intended for "groomed appearance" on a schedule during the growing season and as required throughout the year to provide the desired appearance. (Establish a mowing frequency here that addresses the specific plant species used and theirgrowing habits.) This frequency will be a minimum standard. Particular properties and their peculiar characteristics as well as individual plant species may require mowing more often than the stated minimum may be required. This should be noted in this section. b. The range of turf species suggested for lawns in the three growing regions of North Carolina vary as to optimum maintained height. The selected species should be maintained at a height recommended by the seed producer. Do not cut too short and do not allow the turf to attain a height that will cause the crop to decline or die. Consult individual seed producers and/or packaging for recommended mowing heights. c. Mow with a mulching mower to limit the amount of clippings removed, or mow and blow in such a manner that clippings are not evident and not to adversely effect the growing capacity Rev. 5108 6.11.21 u and/or health of the existing vegetation turf. It is important clippings are allowed to remain spread throughout the lawn area, to the extent possible, so that they might aid in building a more productive soil profile and root zone. 2. Mowing other stabilized areas to promote continued growth. Include mowing specification here for other stabilized areas which require maintenance but not a "groomed" appearance. Also include specifications for mowing areas where it is desirable for woody native volunteer vegetation to become established. This should include attention to mowing stakes or other way of protecting the desired woody natives from the mowing operation, D. Watering 1. Irrigation System Maintenance and Monitoring: If stabilized areas are to be irrigated the design professional should include specifications for the system, its maintenance and its operation in this section. 2. In the absence of an automatic or manual irrigation system, provisions for providing adequate water to stabilized areas should be addressed in this section_ 3. (Provisions should be made in this section for adjustments to application rates of water during times of regulated droughts and/or periods of excessive rainfall.) I?. CONTROL OF 1NVASIVIES: Competition from invasive species can be detrimental to the establishment of the permanent vegetative cover. Left unchecked, these invasives can undermine a revegetation process in a short period of time and eventually lead to unprotected soil and sediment damage. Make site observations monthly to check for the presence of such species and, if found, treat them immediately with the appropriate cultural practices and/or by the use of seasonally -appropriate and site appropriate herbicides, F. Maintenance items including fertilization, mowing, continued soils testing, repair, mulching, matting and soil preparation arc to be addressed in the approved construction sequence and on the project bid list. 6.11.22 Rev. 5/09 • • Practice Standards and .Specifications Definition Application of a protective blanket of straw or other plant residue, gravel, or synthetic material to the soil surface. Purpose To protect the soil surface from the forces of raindrop impact and overland flow. Mulch fosters the growth of vegetation, reduces evaporation, insulates the soil, and suppresses weed growth. Mulch is frequently used to accent landscape plantings. Conditions Where Mulch temporary or permanent seedings immediately. Areas that cannot Practice Applies be seeded because of the season should be mulched to provide temporary protection of the soil surface. Use an organic mulch in this case (but not wood fiber), and seed the area as soon as possible, Mulch around plantings of trees, shrubs, or ground covers to stabilize the soil between plants. Planning A surface mulch is the most effective, practical means of controlling runoff and erosion on disturbed land prior to vegetation establishment. Mulch Considerationsand soil moisture loss by evaporation, prevents crusting and sealing of the soil surface, moderates soil temperatures, provides a suitable microclimate for seed germination, and may increase the infiltration rate of the soil. Organic mulches such as straw, wood chips, and shredded bark have been found to be the most effective. Do -not use materials which may be sources of competing weed and grass seeds. Decomposition of some wood products can tie up significant amounts of soil nitrogen, making it necessary to modify fertilization rates, or add fertilizer with the mulch (Table 6. l4a). A variety of mats and fabrics have been developed in recent years for use as mulch, particularly in critical areas such as waterways and channels. Various types of netting materials are also available to anchor organic mulches. Chemical soil stabilizers or soil binders, when used alone, are less effective than other types of mulches. These products are primarily useful for tacking wood fiber mulches. The choice of materials for mulching should be based on sail conditions, season, type of vegetation, and size ni'the area. A properly applied and tacked mulch is always beneficial. It is especially important, when conditions for m getination are not optimum, such as midsummer and early winter, and on difficult areas such as cut slopes and slopes with southern exposures. ORGANIC MULCHES Straw is the mulch most commonly used in conjunction with seeding. The straw should come from wheat or oats ("small grains"), and may be spread by hand or with a mulch blower. Straw may be lost to wind, and must be tacked down. Wood chips are suitable for areas that will not be closely mowed, and around ornamental plantings. Chips do not require tacking. Because they decompose slowly, they must be treated with 12 pounds of nitrogen per ton to prevent 6. i 4.1 Material Organic Mulches Straw Wood chips Wood fiber Bark Corn stalks Sericea lespedeza seed -bearing stems Nets and Mats' Jute net Fiberglass net Excelsior (wood fiber) mat Fiberglass roving 0 Table 6.14a Mulching Materials and Application Rates Rate Per Acre Quality Notes 1-2 tons Dry, unchopped, Should come from wheat or oats; unweathered; avoid spread by hand or machine; must weeds, be tacked down. 5-6 tons Air dry Treat with 12 ibs nitrogen/ton.

Practice Standards and Specifications nutrient deficiency in plants. This can be an inexpensive mulch if chips are obtained from trees cleared on the site. Bark chips and shredded bark are by-products of timber processing often used in landscape plantings. Bark is also a suitable mulch for areas planted to grasses and not closely mowed. It may be applied by hand or with a mulch blower. Unlike wood chips, the use of bark does not require additional nitrogen fertilizer. Wood fiber refers to short cellulose fibers applied as a slurry in hydroseeding operations. Wood fiber does not require tacking, although tacking agents or soil binders can easily be added to the slurry. Wood fiber hydroseeder slurries may be used to tack straw mulch on steep slopes, critical areas, and where harsh climatic conditions exist. Wood fiber mulch does not provide sufficient erosion protection to be used alone. There are other organic materials that make excellent mulches, but may only be available locally or seasonally, for example: dried sewage sludge, corn stalks, animal manure, pine boughs, cotton burs, peanut hulls, and hay. Creative use of these materials can reduce costs. CHEMICAL, MULCHES AND SOIL BINDERS A wide range of synthetic mulching compounds is available to stabilize and protect the soil surface. These include emulsions or dispersions of vinyl compounds, asphalt, or ribber mixed with water. They may be used alone, or may be used to tack wood fiber hydromulches. When used alone, chemical mulches do not insulate the soil or retain moisture, and therefore do little to aid seedling establishment. They are easily damaged by traffic, are usually more expensive than organic mulches, and they decompose in 60-90 days. Check labels an chemical mulches and binders for environmental. concerns. 'fake precautions to avoid damage to fish, wildlife, and water resources. NETS, MAPS, AND ROVING Netting is very effective in holding mulch in place on waterways and slopes before grasses become established. Mats promote seedling growth in the same way as organic mulches. They are very useful in establishing grass in channels and waterways. A wide variety of synthetic and organic materials are available. "Excelsior" is a wood fiber mat, and should not be confused with wood fiber slurry. When installing nets and mats, it is critical to obtain a firm, continuous contact between the material and the soil. Without such contact, the material is useless, and erosion will occur underneath. Fiberglass roving consists of continuous strands of fiberglass which, when blown onto the soil surface from a special compressed air ejector, form a mat of glass fibers. This mat must then be tacked down with asphalt, 6.14.3 6.14.4 0 Construction Select a material based on site and practice requirements, availability of Specifications material, labor, and equipment. Table 6.14a lists commonly used mulches and some alternatives. Before mulching, complete the required grading, install sediment control practices, and prepare the seedbed. Apply seed before mulching except in the following cases: • Seed is applied as part of a hydroseeder slurry containing wood fiber mulch. • A hydroseeder slurry is applied over straw. APPLICATION -OF ORGANIC MULCH Organic mulches are effective whcrc they can be tacked securely to the surface. Material and specifications are given in Table 6.14a. Spread mulch uniformly by hand, or with a mulch blower. When spreading straw mulch by band, divide the area to be mulched into sections of approximately 1,000 ftz, and place 70-90 lb of straw ( 1 112 to 2 bales) in each section to facilitate uniform distribution. After spreading mulch, no more than 25% of the ground surface should be visible. In hydroseeding operations a green dye, added to the slurry, assures a uniform application. ANCHORING ORGANIC MULCH Straw mulch must be anchored immediately after spreading. The following methods of anchoring mulch may be used; Mulch anchoring tool —A tractor -drawn implement designed to punch mulch into the soil, a mulch anchoring tool provides maximrun erosion control with straw. A regular farm disk, weighted and set nearly straight, may substitute, but will not do a job comparable to the mulch anchoring tool. The disk should not he sharp enough to cut the straw. 'These methods are limited to slopes no steeper than 3:1, where equipment can operate safely, Operate machinery on the contour. Liquid mulch binders —Application of liquid mulch binders and tackifiers should be heaviest at the edges of areas and at crests of ridges and banks, to resist wind. Binder should be applied uniformly to the rest of the area. Binders may be applied after mulch is spread, or may be sprayed into the mulch as it is being blown onto the soil. Applying straw and binder together is the most effective method. Liquid binders include asphalt and an array of commercially available synthetic binders. Emulsified asphalt is the most commonly used mulch binder. Any type thin enough to be blown from spray equipment is satisfactory. Asphalt is classified according to the time it takes to cure. Rapid setting (RS or CRS designation) is formulated for curing in less than 24 hours, even during periods of high humidity; it is best used in spring and fall. Medium setting (MS or CMS) is formulated for curing within 24 to 48 hours, and slow setting (SS or CSS) is formulated for use during hot, dry weather, requiring 48 hours or more curing time. Rev, 12193 40 Practice Standards and Specifications Apply asphalt at 0.10 gallons per square yard (10 gal/1,000 ft'). heavier applications cause straw to "perch" over rills. In traffic areas, uncured asphalt can be picked up on shoes and cause damage to rugs, clothing etc. Use types RS or CRS to minimize such problems. Synthetic binders such as Petroset, `I'erratack, and Aerospray may be used, as reconunended by the manufacturer, to anchor mulch. These arc expensive, and therefore usually used in small areas or in residential areas where asphalt may be a problem (Use of trade names does not constitute an endorsement). Mulch neitings—Lightweight plastic, cotton, jute, wire, or paper nets may be stapled over the mulch according to the manufacturer's recommendations (see "Nets and Mats" below). Peg and twine —Because it is labor-intensive, this method is feasible only in small areas where other methods cannot be used. Drive 8-10 inch wooden pegs to within 3 inches of the soil surface, every 4 feet in all directions. Stakes may be driven before or after straw is spread. Secure mulch by stretching twine between pegs in a Criss -cross -within -a -square pattern. Turn twine two or more times around each peg. Twine may be tightened over the mulch by driving pegs further into the ground. Vegetation ---Rye (grain) may be used to anchor mulch in fall plantings, and Gcnnan millet in spring. Broadcast at 15 lb/acre before applying mulch. CHEMICAL MULCHES Chemical mulches may be effective for soil stabilization if used between May I and June 15, or Sept. 15 and Oct. 15, provided that they are used on slopes no steeper than 4! 1, and that proper seedbed preparation has been accomplished, including surface roughening where required. Chemical mulches may be used to bind other mulches, or with wood fiber in a hydroseeded slurry at any time. Follow the manufacturer's recommendations for application. FIBERGLASS ROVING Fiberglass roving ("roving") is wound into a cylindrical package so that it can be continuously withdrawn from the center using a compressed air ejector. Roving expands into a mat of glass fibers as it contacts the soil surface. It is often used over a straw mulch, but must still be tacked with asphalt. Spread roving uniformly over the area at a rate of 0.25 to 0.35 lb/yd2. Anchor with asphalt immediately after application, at a rate of 0.25 to 0.35 gal/ydz. As a channel lining, and at other sites of concentrated flow, the roving mat must be further anchored to prevent undermining. It may be secured with stakes placed at intervals no greater than 10 feet along the drainageway, and randomly throughout its width, but not more than 10 feet apart. As an option to staking, the roving can be buried to a depth of 5 inches at the upgrade end and at intervals of 50 feet along the length of the channel. NETS AND MATS Nets alone generally provide little moisture conservation benefits and only Rev. l2/93 6.14.5 4 0 limited erosion protection. Therefore, they are usually used in conjunction with an organic mulch such as straw. Except when wood fiber slurry is used, netting should always be installed over the mulcb. Wood fiber may be sprayed an top of an installed net. Mats, including "excelsior" (wood fiber) blankets, are considered protective mulches and may be used alone, on erodible soils, and during all times of the year. Place the matting in firm contact with the soil, and staple securely. INSTALLATION OF NETTING AND MATTING Products designed to control erosion should be installed in accordance with manufacturer's instructions, Any mat or blanket -type product used as a protective mulch should provide cover of at least 36% of the surface where it is applied. Installation is illustrated in Figure 6.14a. 1. Apply time, fertilizer, and seed before laying the net or mat. In channels, roll out strips of netting parallel to the direction of flow and over the protective mulch. Anchor netting in a 12-inch trench 12-i overlap Figure 6.14a Installatonof netting and matling (modified from Va. Div, of Forestry). 6.14.6 Join strips by anchoring and overlapping. Rev. 12M Practice Standards and Specifications 2. Start laying the net from the top of the charrnel or slope, and unroll it down the grade. Allow netting to lay loosely on the soil or mulch cover but without wrinkles —do not stretch. 3. To secure the net, bury the upslope end in a slot or trench no less than 6 inches deep, cover with soil, and tamp firmly as shown in Figure 6.14a. Staple the net every 12 inches across the top end and every 3 ft around the edges and bottom. Where 2 strips of net are laid side by side, the adjacent edges should be overlapped 3 inches and stapled together. Each strip of netting should also be stapled down the center, every 3 ft. Do not stretch the net when applying staples. 4. To join two strips, cut a trench to anchor the end of the new net. Overlap the end of the previous roll 18 inches, as shown in Figure 6.14a, and staple every 12 inches just below the anchor slot. Maintenance Inspect all mulches periodically, and after rainstorms to check for rill erosion, dislocation or failure. Where erosion is observed, apply additional mulch. if washout occurs, repair the slope grade, reseed and reinstall mulch. Continue inspections until vegetation is firmly established.

Purpose 10 retain sediment from small disturbed areas by reducing the velocity of sheet flows to allow sediment deposition. Conditions Where Below small -disturbed areas that are less then %acre per 100 feet of fence. Practice Applies Where runoff can be stored behind the sediment fence without damaging the fence or the submerged area behind the fence. Do not install sediment fences across streams, ditches, or waterways, or other areas of concentrated flow. Sediment fence should be placed along topographic elevation contours, where it can intercept stormwater runoff that is in dispersed sheet flow. Sediment fence should not be used alone below graded slopes greater than 10 feet in height. Planning A sediment fence is a system to retain sediment on the construction site. The Considerations fence retains sediment primarily by retarding flow and promoting deposition. In operation, generally the fence becomes clogged with fine particles, which reduce the flow rate. This causes a pond to develop behind the fence. The designer should anticipate ponding and provide sufficient storage areas and overflow outlets to prevent flows from overtopping the fence. Since sediment fences are not designed to withstand high water levels, locate them so that only shallow pools can form. Tie the ends of a sediment fence into higher ground to prevent flow around the end of the fence before the pool reaches design level. Curling each end of the fence uphill in a "J" pattern may be appropriate to prevent end flow. Provide stabilized outlets to protect the fence system and release storm flows that exceed the design storm. Deposition occurs as the storage pool forms behind the fence, The designer can direct flows to specified deposition areas through appropriate positioning of the fence or by providing an excavated area behind the fence. Plan deposition areas at accessible points to promote routine cleanout and maintenance. Show deposition areas in the erosion and sedimentation control plan. A sediment fence acts as a diversion if placed slightly off the contour. A maximum slope of 2 percent is recommended. This technique may be used to control shallow, uniform flows from small disturbed areas and to deliver sediment -laden water to deposition areas. The anchoring of the toe of the fence should be reinforced with 12 inches of NC DOT #5 or #57 washed stone when flow will nin parallel to the toe of the fence. Sediment fences serve no function along ridges or near drainage divides where there is little movement of water. Confining or diverting runoff unnecessarily with a sediment fence may create erosion and sedimentation problems that would not otherwise occur. Rev. 6106 6.62.1 0 Straw barriers have only a 0-20% trapping efficiency and are inadequate. Straw .bales may not be used in place of sediment fence. Prefabricated sediment fence with the fabric already stapled to thin wooden posts does not meet minimum standards specified later in this section, Anchoring of sediment fence is critical. The toe of the fabric must be anchored in a trench backfilled with compacted earth. Mechanical compaction must be provided in order for the fence to effectively pond runoff. Design Criteria Ensure that drainage area is no greater than %, acre per 100 feet of fence. This is the maximum drainage area when the slope is less than 2 percent. Where all runoff is to be stored behind the fence, ensure that the maximum slope length behind a sediment fence does not exceed the specifications shown in Table 6.62a. The shorter slope length allowed for steeper slopes will greatly reduce the maximum drainage area. For example, a 10-20 % slope may have a maximum slope length of 25 feet. For a 100-foot length of sediment fence, the drainage area would he 25ft X 100f1= 2500sq.ft., or 0.06 acres.

Ensure that the depth of impounded water does not exceed.] .5 feet at any paint along the fence. If non -erosive outlets are provided, slope length may be increased beyond that shown in Table 6,62a, but runoff from the area should be determined and bypass capacity and erosion potential along the fence must be checked. The velocity of the flow at the outlet or along the fence should be in keeping with Table 8.05d, Appendix 8.05. Provide a riprap splash pad or other outlet protection device for any point where flow may overtop the sediment fence, such as natural depressions or swales. Lnsurc that the maximum height of the fence at a protected, reinforced outlet does not exceed 2 feet and that support post spacing does not exceed 4 feet. The design life of a synthetic sediment fence should be 6 months. Construction MATERIALS Specifications 1. Use a synthetic filter fabric of at least 95% by weight of polyolefins or polyester, which is certified by the manufacturer or supplier as conforming to the requirements in ASTM D 6461, which is shown in part in Table 6.62b, Synthetic filter fabric should contain ultraviolet ray inhibitors and stabilizers to provide a minimum of 6 months of expected usable construction life at a temperature range of 0 to 120' F. 6.62.2 Rev. 6106 Practice Standards and Specifications 2.

CONSTRUCTION 1. Construct the sediment barrier of standard strength or extra strength synthetic filter fabrics, 2. Ensure that the height of the sediment fence does not exceed 24 inches above the ground surface. (Higher fences may impound'volumes of water sufficient to cause failure of the structure.) . 3. Construct the filter fabric from a continuous roll cut to file length of the barrier to avoid joints, When joints are necessary, securely fasten the filter cloth only at a support post with 4 feet minimum overlap to the next post. 4. Support standard strength filter fabric by wire mesh fastened securely to the upslope side of the posts. Extend the wire mesh support to the bottom of the trench. Fasten the wire reinforcement, then fabric on the upslope side of the fence post. Wire or plastic zip ties should have minimum 50 pound tensile strength. 5. When a wire mesh support fence is used, space posts a maximum of 8 feet apart. Support posts should be driven securely into the ground a minimum of 24 inches. 6. Extra strength filter fabric with 6 feet post spacing does not require wire mesh support fence. Securely fasten the filter fabric directly to posts. Wire or plastic zip ties should have minimum 50 pound tensile strength: Rev. 6106 6.62.3 3 0 7. Excavate a trench approximately 4 inches wide and 8 inches deep along the proposed line of posts and upslopc from the barrier (Figure 6.62a). 8, Place 12 inches of the fabric along the bottom and side of the trench. 9. Backfill the trench with soil placed over the filter fabric and compact. Thorough compaction of the backfill is critical to silt fence performance. 10. Do not attach filter fabric to existing trees. SEDIMENT FENCE INSTALLATION USING THE SLICING METHOD Instead of excavating a trench, placing fabric and then backfilling trench, sediment fence may be installed using specially designed equipment that inserts the fabric into a cut sliced in the ground with a disc (Figure 6.62b). Installation 1. The base of both end posts should be at least one foot higher than the Specifications middle of the fence. Check with a level i f necessary. 2. Install posts 4 feet apart in critical areas and 6 feet apart on standard applications. 3. Install posts 2 feet deep on the downstream side of the silt fence, and as close as possible to the fabric, enabling posts to support the fabric from upstream water pressure. 4. Install posts with the nipples facing away from the silt fabric. 5. Attach the fabric to each post with three ties, all spaced within the top 8 inches of the fabric. Attach each tie diagonally 45 degrees through the fabric, with each puncture at least 1 inch vertically apart. Also, each tie should be positioned to hang on a post nipple when tightened to prevent sagging. 6. Wrap approximately 6 inches of fabric around the end posts and secure with 3 ties. 7. No more than 24 inches of a 36 inch fabric is allowed above ground level. 8. The installation should be checked and corrected for any deviations before compaction. 9. Compaction is vitally important for effective results. Compact the soil immediately next to the silt fence fabric with the front wheel of the tractor, skid steer, or roller exerting at least 60 pounds per square inch. Compact the upstream side first, and then each side twice for a total of 4 trips. 6.62.4 Rev. 6/06 Steel post Practice Standards and Specifrcaliuns 8' max. standard strength fabric with wire fence 6' max. extra strencth fabric without wire fence Plastic or wire ties Wire r` ''r7 18-24 fence 1 rr ,.' hr Natural ground 8" down '14' forward along 24" the trench Filter fabric Wire fence Cros5-Section View Filter Steel fabric Backfill trench Natural post / and compact ground �horougitly • 4'• Up64ope . ; ' • min 8' MM •' Figure 6.62a installation detail of a sediment Fence.

This letter report presents the results of the most recent semi-annual sampling event that was completed at the Dare County C&D Landfill and constitutes the second semi-annual sampling event for 2011. The approved groundwater monitoring network consists of 13 wells (MW-1, -2, -3, -8, -9, -10, -11, -12, -13, -14, -15, -16, and -17) and 3 surface water sampling locations (SW-1, -2, and —3). Field activities and sampling results for all wells and surface water sampling locations are discussed below. Field Activities Groundwater and surface water samples from the Dare County C&D Landfill were collected on August 22 and October 18, 2011 by Environment One, Inc. Groundwater elevations were measured at each well prior to sampling and are presented in Table 1. These groundwater elevations were used to construct a potentiometric surface map for this sampling event. The potentiometric contours and sampling locations are presented on Figure 1. Prior to sampling each well was measured in the field for pH, conductivity, temperature, and total dissolved solids. The water quality parameters at the time of sampling are also presented in Table I. Sampling Results Environment One, Inc. in Greenville, North Carolina analyzed groundwater samples for the North Carolina Appendix I volatile organic compounds (VOC's), metals, and select inorganics. in accordance with Solid Waste Section guidelines the analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below Solid Waste Section Limits (SWSLs). All monitoring wells and surface water sample locations for the C&D Landfill had detections of analytes above the MDL with a majority of the detections below SWSLs. These detections were qualified as estimated or "J" flags.

This letter report presents the results of the most recent semi-annual sampling event that was completed at the Dare County C&D Landfill and constitutes the first semi-annual sampling event for 2012. The approved groundwater monitoring network consists of 13 wells (MW-1, -2, -3, -8, -9, -10, -11, -12, -13, -14, -15, -16, and -17) and 3 surface -water sampling locations (SW-1, -2, and —3). Field activities and sampling results for all wells and surface water sampling locations are discussed below. Field Activities Groundwater and surface water samples from the Dare County C&D Landfill were collected on February 16, 2012 by Environment One, Inc. Groundwater elevations were measured at each well prior to sampling and are presented in fable 1. These groundwater elevations were used to construct a potentiometric surface map for this sampling event. The potentiometric contours and sampling locations are presented on Figure 1. Prior to sampling each well was measured in the field for pH, conductivity, temperature, and total dissolved solids. The water quality parameters at the time of sampling are also presented in Table 1. Sampling Results Environment One, Inc. in Greenville, North Carolina analyzed the groundwater and surface water samples for the North Carolina Appendix I volatile organic compounds (VOC's) by U.S. Environmental WATER + ENVIRONMENT+ TRANSPORTATION+ ENERGY + FACILITIES `:✓ ID i r moth, .Ms. Jaclynne Drummond March 20,1012 Page 2 Protection Agency'(EPA) Method'$260B; metals by EPA Method'200.8 and'Standard Method (SM) 3113B,.alkalinity bySM-2320B,,chloride by 4500'CL B; and sulfate by SM426C. In accordance with Solid Waste'Section guidelines the analytical.results were reported to the laboratory specific method_ detection limit.(MDL) and are quantifiable at or below Solid Waste Section Limits (SWSLs)..A11 monitoring wells and surface water sample,locations for the C&D Landfill'had detections of.anaiytes above the MDL witli a,majority of theidetections.below SWSLs. These A etections were qualifted.as estimated,or "J"flags, The following list,presents•the analytes detected above the:MDL at each sample location. No"J" flag detections'are provided. Underlined analytes exceeded th-e,Norih.Carolina 2L Standard (NC 2L);.

The NOI shall be submitted and a certificate of coverage issued prior to any discharge of stormwater associated with industrial activity, mine dewatering wastewater, or process wastewater that has a point source discharge to the surface waters of the state. This General Permit covers mining and quarrying of nonmetallic minerals (except fuels) including borrow pits (that would not be covered under the statewide DOT stormwater permit) and active or inactive mines that discharge stormwater contaminated with, or that has come in contact with, any overburden, raw material, intermediate products, finished products, byproducts or waste products located at the site of such operations and stormwater runoff from vehicle maintenance areas. This General Permit also covers discharge of wastewater from processing mined materials and mine dewatering wastewater from the groundwater and/or stormwater that accumulates in the mine pit. Any owner or operator not wishing to be covered or limited by this General Permit may make application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual permit should be made at least 180 days prior to commencement of discharge. This General Permit does not cover activities or discharges covered by an individual NPDES permit until the individual permit has expired or has been revoked. Any person conducting an activity covered by an individual permit but which could be covered by this General Permit may request that the individual permit be. revoked and coverage under this General Permit be provided. Any facility may apply for new or continued coverage under this permit until a Total Maximum Daily Load (TMDL) for pollutants for stormwater or wastewater discharges is established. A TMDL sets a pollutant -loading limit that affects a watershed, or portion of a watershed, draining to an impaired water. For discharges to watersheds affected by a TMDL, coverage under this permit may depend on the facility demonstrating it does not have reasonable potential to violate applicable water quality standards for those pollutants as a result of discharges. If the Division determines that discharges have reasonable potential to cause water quality standard violations, the facility shall apply for an individual permit 180 days prior to the expiration date of this general permit. Once that individual permit is effective, the facility will no longer have coverage under this general permit. [Note the permittee must identify impaired waters (scheduled for TMDL development) and waters already subject to a TMDL in the Site Plan, as outlined in the Stormwater Pollution Prevention Plan (SPPP), Part III, Section A. Parts 1-11 Page 1 of 4 Permit No. NCG020000 SECTION B. PERMITTED ACTIVITIES Until this permit expires or is modified or revoked, the permittee is authorized to discharge stormwater, mine dewatering, and/or process wastewater to the surface waters of North Carolina or a separate storm sewer system which has been adequately treated and managed in accordance with the terms and conditions of this General Permit. Types of approved discharges are dependent upon approval and are detailed in the permittee's individual Certificate of Coverage (COC). All discharges shall be in accordance with the conditions of this permit. Any other point source discharge to surface waters of the state is prohibited unless it is an allowable non-stormwater discharge or is covered by another permit, authorization, or approval. If mining activities will expand or change such that the types of discharges are affected, the permittee is to contact DWQ to determine if modifications to the COC are necessary first. The permittee is also responsible for contacting the Division of Land Resources (DLR) if modifications to the Mining Permit are necessary, as compliance with the Mining Permit is a stipulation of this permit. The discharges allowed by this General Permit shall not cause or contribute to violations of Water Quality Standards. Discharges allowed by this permit must meet applicable wetland standards as outlined in 15A NCAC 213.0230 and .0231 and water quality certification requirements ® as outlined in 15A NCAC 2H .0500. This permit does not relieve the permittee's responsibility for compliance with any other applicable federal, state or local law, rule, standard, ordinance, order or decree.

The stormwater management plan shall contain a Q narrative description of the materials management practices employed which control or ® minimize the exposure of significant materials to stormwater, including structural and nonstructural measures. The stormwater management plan, at a minimum, shall © incorporate the following: 0 ® (a) Management of Stormwater Runoff and Runon. The permittee shall maintain stormwater BMPs for mine excavation and disturbance areas, process areas, and A any other areas associated with mining or vehicle maintenance activities. In addition, controls should be used to limit or isolate selected land disturbance and process areas and limit the amount of off site stormwater runon to those areas. A Appropriate Best Management Practices (BMPs) should be used to divert, infiltrate, reuse or otherwise manage stormwater runoff and runon in a manner that reduces pollutants in stormwater discharges leaving the site. Appropriate BMPs may include but are not limited to: vegetative swales, berms, use of reclaimed mine ® areas, and reuse of collected stormwater (such as for an industrial process or as an irrigation source). (b) BMP Controls Inspection and Maintenance. All stormwater controls shall be 0 inspected. All inspections are to be documented with a written record of repairs. BMPs shall be inspected by or under the direction of the permittee at least once 0 every seven calendar days and within 24 hours after any storm event that results in 0 a discharge, unless the site is inactive, Reduced Inspections for inactive mines: For inactive mines that have obtained an ® "Inactive Renewal" Mining Permit from DLR, BMPs must be inspected at least once every month, and within 24 hours of any storm event of 0.5 inches or more. For mines where active mining has suspended temporarily, but the mine maintains an active Mining Permit from DLR, the permittee must certify to DWQ that all portions of the site where clearing, grading, and/or excavation activities have temporarily ceased have been stabilized with vegetation, and may then conduct BMP inspections within 24 hours of any storm event that results in a discharge (no weekly minimum). The permittee must send certification to the DWQ Regional "inactive" Office of status and may be subject to an inspection for verification. The permittee must also notify the Regional Office upon resuming mining activities. A rain gauge and monitoring records are to be kept on site. BMPs shall be operated and maintained. BMPs must be cleaned out when sediment storage capacity is at 50% permitted volume. If visible sedimentation is leaving the property, corrective Part III Page 2 of 16 Pages Permit No. NCG020000 action shall be taken to reduce the discharge of sediments, Visible sedimentation shall be recorded with a brief explanation of measures taken to prevent future releases, as well as any measures taken to remove the sediment that has left the site. Visible sedimentation records shall be kept onsite. All other stormwater specific controls (e.g. oil/water separators) shall be inspected and qualitatively monitored (as per Part III. D) on a semi-annual schedule. A log of all sampling data, including activities taken to implement BMPs associated with vehicle maintenance activities, shall be maintained and incorporated into the SPPP and kept onsite and available for inspection purposes. These items shall be available for the duration of the permit term and made available to the Director upon request. These data shall be sent to the Regional Office upon request. (c) Secondary Containment Requirements and Records. Secondary containment is required for: bulk storage of liquid materials; storage in any amount of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals; and storage in any amount of hazardous substances, in order to prevent leaks and spills from contaminating stormwater runoff. A table or summary of all such tanks and stored materials and their associated secondary containment areas shall be maintained. If the secondary containment devices are connected to stormwater conveyance systems, the connection shall be controlled by manually activated valves or other similar devices (which shall be secured closed with a locking mechanism), and any stormwater that accumulates in the containment area shall be at a minimum visually observed for color, foam, outfall staining, visible sheens and dry weather flow, prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated by any material. Records documenting the individual making the observation, the description of the accumulated stormwater, and the date and time of the release shall be kept for a period of five (5) years. 4. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall incorporate an assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel (or the team) responsible for implementing the SPRP shall be identified in a written list incorporated into the SPRP and signed and dated by each individual acknowledging their responsibilities for the plan. A responsible person shall be on -site at all times during facility operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP, but may not be sufficient to completely address the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be incorporated by reference into the SPRP. 5, Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good housekeeping program shall be developed and implemented. The program shall ensure equipment used during mining activity on a site must be operated and maintained to prevent potential pollution of the surface water or groundwaters of the state. Fuels, lubricants, coolants, hydraulic fluids, or any other petroleum products shall not be discharged on the ground or into surface waters. Spent lubricants and fuels shall be disposed of properly and in accordance with applicable federal disposal regulations. Spilled fluids shall be cleaned up to the maximum extent practicable and properly disposed of to prevent entry to surface waters or groundwaters of the state. The program shall establish schedules of inspections, maintenance, and housekeeping measures for vehicle maintenance and industrial activity areas (including material storage and handling areas, Part IIl Page 3 of 16 Pages 0 Permit No. NCG020000 ® disposal areas, process areas, loading and unloading areas, and haul roads), where not already addressed under another element of this Plan. Schedules for inspections, ® maintenance, and housekeeping, and documentation that these program elements are being implemented, shall be recorded and maintained in the SPPP. 6. Employee Training. Training programs shall be developed and training provided at a minimum on an annual basis for facility personnel with responsibilities for: spill response Q and cleanup, preventative maintenance activities, and for any of the facility's operations o that have the potential to contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the training shall be identified, and their annual training shall be documented by the signature of each employee trained. Additional required training items include: used oil management, spent solvent management, disposal of spent abrasives, disposal of vessel wastewaters, fueling procedures, sanding, painting and blasting procedures, and used battery management. 7.

Responsibilities for all components of the Plan shall be documented ® and position assignments provided. B. Plan Amendment. The permittee shall amend the Plan whenever there is a change in Q design, construction, operation, or maintenance that has a significant effect on the potential Q for the discharge of pollutants to surface waters. All aspects of the Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual basis. The annual update shall include an updated list of significant spills or leaks of pollutants for the previous three (3) years, or the notation that no spills have occurred. The annual update shall include written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. Each annual update shall include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management • Plan. The Director may notify the permittee when the Plan does not meet one or more of the minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit a time schedule to the Director for modifying the Plan to meet minimum S requirements. The permittee shall provide certification in writing (in accordance with Part VI, Standard Conditions, Section B, Paragraph 5) to the Director that the changes have been made. ® 9. Plan Implementation. The permittee shall implement the Plan and all appropriate BMPs to ensure that contaminants do not enter surface waters via stormwater that comes in 0 contact with any unstabilized overburden, raw materials, intermediate products, finished products, byproducts or waste products located on the site covered by this permit. Implementation of the Plan shall include documentation of all monitoring, measurements, inspections, maintenance activities, and training provided to employees, including the log of the sampling data and of actions taken to implement BMPs associated with the industrial activities, including vehicle maintenance activities. Such documentation shall be kept on - site for a period of five years and made available to the Director or the Director's authorized ® representative immediately upon request. SECTION B: STORMWATER DISCHARGES: ANALYTICAL MONITORING REQUIREMENTS • Stormwater discharges are defined as stormwater from mining activity areas, including (but not limited to) areas of mine excavation, other land disturbance, process areas, and vehicle ® maintenance. This section does not apply to wastewater discharges from mine dewatering ® Part III Page 4 of 26 Pages 0 Permit No. NCG020000 and process areas. Analytical monitoring for stormwater discharges shall be performed for parameters as specified in Tables 1 through 3. All analytical monitoring shall be performed during a representative storm event as defined below. Monitoring Exemption Analytical monitoring is not required for any basin or pond designed to contain the 25-year, 24- hour storm (see Part V1I, Definitions) without discharging, and that can regain capacity to hold such an event within five (5) days' time through means other than discharge to surface waters. A basin or pond that meets this provision is considered a non -discharging stormwater control. Table 1.

Measurement Frequency: Twice. per year during a representative storm event, as defined for this permit. Failure to comply with semi-annual monitorine in accordance with Dermit terms for anv six-month monitoring period immediately triggers, monthlymonitoringfor the remaining permit term. 2. Grab samples shall be collected within the first 30 minutes of discharge. For sites where multiple outfalls are separated by distances that preclude collection within 30 minutes of each discharge event is not feasible, begin collection procedures within 30 minutes and continue until all outfalls with discharges are sampled. Documentation explaining why it was not possible to take samples within the first 30 minutes must be kept in the SPPP. 3. Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative outfall status (ROS) has been granted and documented by the Division of Water Quality. A copy of the letter granting ROS shall be kept on site. 4. Turbidity may be monitored at the Stormwater Discharge Outfall. Alternatively, the permittee may choose to monitor turbidity in the receiving water, directly upstream and downstream of the stormwater discharge outfall(s). S. For each sampled representative storm event the total precipitation must be recorded. An on -site rain gauge or local rain gauge reading must be recorded. 6. Total flow shall be: (a) measured continuously, or (b) calculated based on the amount of area draining to the outfall, the amount of impervious area, and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute intervals during the rainfall event. Total rainfall precipitation and duration of the rainfall event refers to the representative storm event sampled. All analytical monitoring shall be performed during a representative storm event at each stormwater discharge outfall (SDO). The permit allows the permittee to monitor turbidity at the SDO or up- and downstream of the SDO; however, the permittee should consider regular turbidity sampling up- and downstream of the discharge(s) when feasible to ensure compliance with water quality standards. Part III Page 5 of 16 Pages Permit No. NCG020000 A representative storm event for the purposes of this General Permit is a storm event that measures greater than 0.1 inches of rainfall. The time between this storm event and the previous storm event measuring greater than 0.1 inches must be at least 48 hours. One storm event may have a time period within it that has no precipitation. This time period may last up to 10 hours. For example, if it rains but stops before producing any collectable discharge, a sample may be collected if the next rain producing a discharge begins within 10 hours, 4) The permittee shall complete the analytical samplings in accordance with the schedule specified in O Table 2. A minimum of 60 days must separate each sample event unless monthly monitoring has been instituted under a Tier 2 response. Failure to comply with, semi-annual monitoring in accordance with permit terms for any six-month monitoring period immediately- triggers monthly monitoring for the remaining permit term, unless adverse weather conditions prevent sample collection during the sample collection period. Inability to sample due to adverse weather conditions must be documented in the SPPP with date, time and written narrative (see Adverse • Weather in Definitions) and reported on the Annual Summary DMR. Table 2. Monitoring Schedule Semi-annual Monitoring Eventsl.7 Start Date (All Years)3 End Date (All Years) 3 1 januag 1 June30 2 1 Illy- 1 December 31 Footnotes: 1. Maintain semi-annual monitoring during permit renewal process (unless tiers prompt monthly). If at the expiration of the General Permit, the permittee has submitted an application for renewal of coverage before the submittal deadline, the permittee will be considered for renewed coverage. The applicant must continue monitoring until the renewed Certificate of Coverage is issued. 2. If no discharge occurs during the sampling period, the permittee must record "No Flow" or "No Discharge" within 30 days of the end of the six-month sampling period in the SPPP. "No Flow" or "No Discharge" shall be reported on the Annual Summary Discharge Monitoring Reports (DMR). This DMR is to be submitted to the Division's Central Office by March 1 of each year. 3. Monitoring periods remain constant throughout the five-year permit term (from January 1, 2010 to December 31, 2014). In all cases, the permittee shall report (as required in Part IV, Section E.) the analytical results from each sample within the monitoring period. The permittee shall compare those results to the benchmark values in Table 3• Exceedences of benchmark values require the permittee to increase monitoring, increase management actions, increase record keeping, send the monthly monitoring results to the appropriate Regional Office, and/or install stormwater Best Management Practices (BMPs) in a tiered program. See below the descriptions of tiered response actions. Table 3. Benchmark Values for Stormwater Discharges Discharge Characteristics Benchmark Values Settleable Solids 0.1 MI/1 Total Suspended Solids (TSS) 100 m TSS ORW, H W, trout, and PNA waters 50 mg/1 Turbidity N/A See below Part III Page 6 of 16 Pages Permit No. NCG020000 The discharge shall not cause the turbidity of the receiving water to exceed Water Quality Standards: 10 NTU freshwater streams, lakes, and reservoirs designated as trout waters 25 NTU all lakes and reservoirs, and all salt waters 50 NTU all other streams and surface waters If turbidity of the receiving stream exceeds these levels due to natural background conditions, the existing turbidity level shall not be increased. If the turbidity exceeds these levels as a result of stormwater discharges, the permittee must immediately institute Tier 2 response actions, including monthly monitoring of all stormwater discharge outfalls to the receiving waters. The permit allows the permittee to monitor turbidity in the effluent or up- and downstream of the discharge point; however, the permittee should consider regular turbidity sampling up- and downstream of the discharge(s) when feasible to ensure compliance with water quality standards Tier One If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at any outfall; Then: The permittee shall 1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling results. 2. Identify and evaluate possible causes of the benchmark value exceedence. 3. Identify potential and select the specific: source controls, operational controls, or physical improvements to reduce concentrations of the parameters of concern, or to bring concentrations within the benchmark range. 4. Implement the selected actions within two months of the inspection. S. Record each instance of a Tier One response in the Stormwater Pollution Prevention Plan. Include the date and value of the benchmark exceedence, the inspection date, the personnel conducting the inspection, the selected actions, and the date the selected actions were implemented. 6. Send all monitoring results for that sample period to the appropriate DWQ Regional Office. Part III Page 7 of 16 Pages Permit No. NCG020000 I Tier Two If: During the term of this permit, the first valid sampling results from two (2) consecutive monitoring periods are above the benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall; Then: The permittee shall 1. Repeat all the required actions outlined above in Tier One. 2. Immediately institute monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark value for two (2) consecutive samples, Monthly (analytical and qualitative) monitoring shall continue until three (3) consecutive samples are below the benchmark values or within the benchmark range. 3. Send all monthly monitoring to the appropriate DWQ Regional Office, 4. If no discharge occurs during the sampling period, the permittee is required to record "No Flow" or "No Discharge" in the SPPP for the sampling the period to comply with monthly monitoring requirements and must submit reports in accordance with this permit. 5. Maintain a record of Tier Two responses in the Stormwater Pollution Prevention Plan. Tier Three During the term of this permit, if the valid sampling results required for the permit monitoring periods exceed the benchmark value, or are outside the benchmark range, for any specific parameter at any specific outfall on four (4) occasions, the permittee shall notify the DWQ Regional Office Supervisor in writing within 30 days of receipt of the fourth analytical results. DWQ may but is not limited to: • Require that the permittee revise, increase, or decrease the monitoring frequency for the remainder of the permit; • Rescind coverage under the General Permit, and require that the permittee to apply for an individual stormwater discharge permit; • Require the permittee to implement in -stream Turbidity Monitoring (U,D) • Require the permittee to install or modify structural stormwater controls; or • Require the permittee to implement other stormwater control measures SECTION C: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS (STORMWATER DISCHARGES) Facilities which have any on -site vehicle maintenance activity that uses more than 55 gallons of new motor oil per month when averaged over the calendar year shall perform analytical monitoring as specified below in Table 4.

If the permittee repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if the discharge causes or contributes to a water quality standard violation, DWQ may but is not limited to: • Require that the permittee revise, increase, or decrease the monitoring frequency for the remainder of the permit; • Rescind coverage under the General Permit, and require that the permittee to apply for an individual stormwater discharge permit; • Require the permittee to implement in -stream Turbidity Monitoring (U,D) • Require the permittee to install or modify structural stormwater controls; or • Require the permittee to implement other stormwater control measures SECTION E: WASTEWATER DISCHARGES: EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS FOR MINE DEWATERING WASTEWATER & PROCESS WASTEWATER RMM in, -I UATIMMURM7.Wfunda Mine dewatering requirements apply to all mines that dewater from pits including quarries, clay brick, sand & gravel, borrow pits, and refractory. mining, as well as mines with similar discharges. Note that for Construction Sand and Gravel or Industrial Sand mines, "mine dewatering" wastewater includes wet pit overflows caused solely by direct rainfall and groundwater seepage. During the period beginning on the effective date of the permit and lasting until expiration, the permittee is authorized to discharge mine dewatering wastewater controlled in accordance with the conditions of this permit. Mine dewatering activities that have the potential to drain wetlands or other surface waters must have secured and implemented a Pumping Operation and Monitoring (O&M) Plan approved by the Division. Pumping 0&M Plans shall include, but are not limited to: • Groundwater monitoring strategies to demonstrate the effect of pumping. • Detailed plans to maintain the surrounding hydrology that protects the affected streams and wetlands and the respective monitoring to demonstrate compliance. • The pumping regime deemed necessary to protect affected streams and wetlands. Alternative site specific pumping and monitoring regimes may be approved by the Division on a case -by -case basis. At the Division's discretion, approval of the Pumping 0&M Plan may be required prior to coverage under this general permit. Analytical monitoring of mine dewatering-wastewater shall be performed as specified below in Table 7. For each parameter, an effluent limitation is contained in Table B. An exceedence of any of these limitations is a violation of the permit conditions and may be subject to enforcement action as specified in Part IV, Section A.2 of this permit.

Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with this General Permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the General Permit. It shail not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this General Permit. By_pgssing of Stormwater Control Facilities Bypass is prohibited and the Director may take enforcement action against a permittee for bypass unless: a. Bypass was unavoidable to prevent 1 oss of I ife, personal injury or severe property damage; and b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities, retention of Stormwater or maintenance during normal periods of equipment downtime or dry weather. This condition is not satisfied if adequate backup controls should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and C. The permittee submitted notices as required under Section E of this Part. If the Director determines that it will meet the three conditions listed above, the Director may approve an anticipated bypass after considering its adverse effects. Parts IV, V, and VI Page 5 of 9 Pages Permit No. NCG020000 SECTION D: MONITORING AND RECORDS Representativg$ampling Samples collected and measurements taken, as required herein, shall be characteristic of the volume and nature of the permitted discharge. Analytical sampling shall be performed during a representative storm event. Samples shall be taken on a day and time that is characteristic of the discharge. All samples shall be taken before the discharge joins or is diluted by any other waste stream, body of water, or substance. For each measurement, sample, inspection or maintenance activity performed or collected pursuant to the requirements of this General Permit, the permittee shall record the following information: a. The date, exact place, and time of sampling, measurements, inspection or maintenance activity; b. The individual(s) who performed the sampling, measurements, inspection or maintenance activity; C.

To meet the intent of the monitoring required by this General Permit, all test procedures must produce minimum detection and reporting levels and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. 5. Representative Outfall If a facility has multiple discharge locations with substantially identical stormwater discharges that are required to be sampled, the permittee may petition the Director for representative outfall status. If it is established that the stormwater discharges are substantially identical and the permittee is granted representative outfall status, then analytical sampling requirements may be performed at a reduced number of outfalls. Qualitative monitoring shall be documented and records maintained at the facility along with the Stormwater Pollution Prevention Plan. Copies of analytical monitoring results shall also be maintained on -site. The permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, and copies of all reports required by this General Permit for a period of Parts IV, V, and VI Page 6 of 9 Pages Permit No. NCG020000 at least 5 years from the date of the sample, measurement, report or application.

This O&M Plan is intended to address the following issues: ■ Pump Maintenance and Recording, ■ Groundwater Monitoring, ■ Wetlands Monitoring, ■ Stormwater and Mining Permit Requirements, ■ Operating Record and Recordkeeping Requirements. Site Background The site is located in a relatively remote area of mainland Dare County. The existing borrow area is surrounded by wetlands and prior converted cropland currently utilized for agriculture. The entire Dare County site is bounded on the east by U.S. Highway 264 and on the other three sides by the Alligator River National Wildlife Refuge. The existing borrow area has been in operation since 1995 to provide:cover soil for the active C&D landfill. The existing excavation started. approximately 150 feet south of the canal adjacent to Cub Road, to minimize the effects of groundwater flow changes on the C&D landfill groundwater monitoring system, and has continued to be performed at an average of 18-20 feet below ground surface extending south toward Grouse Road (See attached Sheet C-1). Excavation is performed in increments as 'necessary to supply base fill, daily cover, and cap construction for the C&D landfill. Dewatering of the excavation occurs as necessary. Excavated material is temporarily stockpiled in the stockpile'area and, after adequate drainage, is used at the C&D landfill site. In accordance with the approved mining permit, as the final edges of the excavation pit are completed, excavation equipment operators will ensure that the final below water table surface slopes comply with the specifications outlined above. A free'settling slope will be maintained on the active face until final excavation is complete. Warning signs are placed at the four corners of the excavation area. In the mining area, land disturbing -activities are accomplished such that all stormwater runoff are directed into the mining pit. Drainage into the southern mining pit (Mining'Excavation Pit 3) drains north where it is pumped into Mining Excavation Pit 2. Mining Excavation:Pit 2 gravity drains into Mining Excavation Pit 1. All water discharged from Mining Pit 1 gravity drains from the discharge of Mining Pit 1 and flows west along Cub Road. At the intersection of Cub Road and Sear Road, drainage is directed north and discharges from the property at the intersection of Bear Road and Gadwell Road. Two surface drainage ditches drain the -Tf .� 01 r 1 P,10a�r Coa1RY•17i721pwrorr Pl O6M MvNq W Oat. GWro Pd OtM R+ F,ML10212011 — 1-1 Dare County C&D Landfill Borrow Pit Operation and Maintenance Plan stockpile area. Sedimentation basins are constructed in each of the two ditches to treat stormwater and soil drainage. Based on pump curve data, it is estimated that the maximum discharge rate for the dewatering operation at the pit is approximately 1,200 gpm or 1.7 MGD. It is likely that discharge rates are typically lower than 1,200 gpm and vary based on head. withdrawn water from the current excavation (Pit 3) is pumped to an adjacent pit and ultimately discharges to a series of canals on site, as described above. O&M Procedures The following sections discuss O&M procedures to be followed for the borrow pit activities at the site. A spreadsheet to be used as a weekly general inspection checklist has been generated based on the following activities. The weekly inspection checklist is provided as Table 1. The weekly general inspection checklists will be maintained in a,dedicated folder or file and kept in the scale house. In addition, as required in the Mining Permit, qualitative inspection and analytical discharge monitoring will be conducted at the outfali from Mining Pit 1 to the canal. A Stormwater Discharge Outfall (SDO) Qualitative Inspection Monitoring form is attached. The qualitative inspection monitoring form is to be completed weekly and during any storm event greater than 0.10 inches and will be kept on file in the scale house. If no discharge occurs during that period, the Form should be filled out as "no flow." Pump Maintenance and Recording There is no meter present to monitor discharge rates from the borrow pit to the adjacent pit, however, there is an hour meter at the pump. Pumping rates vary as head fluctuates, but the pump is never turned off. In the event of interruption or variation from the typical pumping rate and time, County staff shall record time that pump was not active and describe reason for inactivity on the weekly inspection checklist. Groundwater Monitoring In order to monitor the effects of prolonged pumping of the surficial aquifer on the area surrounding the borrow pit, 4 new monitoring wells have been installed (Well-1 through Well-4). The wells were surveyed to State Plane coordinates and NAVD 88 elevation. Well' locations are shown on the attached Wetiond Flag Location Map. Water levels in the wells are to be measured from the top of the PVC casing quarterly. All water measurements shall be recorded on the corresponding weekly inspection checklist. Wetlands Monitoring The wetland areas adjacent to the borrow pit have been flagged and mapped (see attached Wetland Flag Location Map). These areas and the adjacent ditches are to be visually inspected for signs of vegetative stress or abnormality and water level/flow. within the ditches on a weekly basis. All observations from the weekly wetland inspectionsshall be recorded on the weekly inspection form. t-2 P.Oua County-17057,0wn P409M P1iMRdYWed OLa OWIe PAOAMPLt_Final_702UOt atl Dare County C&D Landfill Borrow Pit Operation and Maintenance Plan Stormwater Qualitative Inspection Monitoring Stormwater qualitative inspection monitoring shall be conducted at the outfall from Mining Pit 1 weekly and during any storm event greater than 0.10 inches. Qualitative inspection monitoring shall include descriptions and observations made at the outfall and include: Color; odor; clarity; floating solids; suspended solids; foam; oil sheen; indications of sediment deposition; indications of erosion; and any other obvious indication of stormwater pollution. If no discharge occurs for that period, the form shall be filled out as "no flow." All weekly qualitative inspections shall be recorded on the attached Stormwater Discharge Outfall (SDO) Qualitative Inspection Monitoring form and kept on file in the scale.house. If obvious indications of turbidity, erosion or sedimentation are observed, perform maintenance as necessary. Storm water Analytical Monitoring Stormwater analytical monitoring shall be conducted at the outfall from Mining Pit 1 semi- annually during a representative storm event that causes discharge. Samples for Settleable Solids and Total Suspended Solids shall be collected and sent to an offsite laboratory for analysis. Field measurements of turbidity shall also be collected at the outfall during these events. Total Rainfall, Event Duration, and Total Flow shall also.be recorded on the Stormwater Discharge Outfall (SOO) Qualitative Inspection Monitoring form. Semi-annual analytical data and rainfall data will be recorded on a Discharge Monitoring Form and kept on file in the scale house. However, if any parameter benchmark is exceeded for a semi-annual event, a Stormwater Exceedence DMR form will be forwarded to the Regional DWQ office within 30 days of receipt of the analytical data. Analytical results for the semi-annual events will be compiled in an Annual Discharge Monitoring Form for submittal to the Central DWQ office by March 1 of the following year. Semi-annual stormwater samples shall be collected between January 1—June 30 and July 1 — December 31, with a minimum of 60 days between samples. Mine Dewatering Discharge Analytical Monitoring In addition to the semi-annual Stormwater monitoring,. quarterly analytical sampling must be conducted at the outfall to monitor general effluent quality from the dewatering activities. Samples are to be collected and analyzed for pH, Settleable Solids, Total Suspended Solids, and Turbidity. Total dewatering.volume for the date of sample collection must also be recorded: Pump volume can be estimated from pump hour recordings from Table i and pump curves. Quarterly effluent analytical data will be recorded on a Discharge Monitoring Form and will be kept'on file in the scale house. However, if any parameter limit is exceeded, or a violation is found for any quarterly event, an Effluent Exceedence DMR form will be forwarded to the Regional DWQ office within 30 days of receipt of the analytical data.

This O&M Plan is intended to address the following issues: ■ Pump Maintenance and Recording, ■ Groundwater Monitoring, ■ Wetlands Monitoring, ■ Stormwater and Mining Permit Requirements, • Operating Record and Recordkeeping Requirements. Site Background The site is located in a relatively remote area of mainland Dare County. The existing borrow area is surrounded by wetlands and prior converted cropland currently utilized for agriculture. The entire Dare County site is bounded on the east by U.S. Highway 264 and on the other three sides by the Alligator River National Wildlife Refuge. The existing borrow area has been in operation since 1995 to provide cover soil for the active C&D landfill. The existing excavation started approximately 150 feet south of the canal adjacent to Cub Road, to minimize the effects of groundwater: flow changes on the C&D landfill groundwater monitoring system, and has continued to be performed at an average of 18-20 feet below ground surface extending south toward Grouse Road (See attached Sheet C-1). Excavation is performed in increments as'necessary to supply base fill, daily cover, and cap construction for the C&D landfill. Dewatering of the excavation occurs as necessary. Excavated material is temporarily stockpiled in the stockpile area and, after adequate drainage, is used at the C&D landfill site. In accordance with the approved mining permit, as the final edges of the excavation pit are completed, excavation equipment operators will ensure that the final below water table surface slopes comply with the specifications outlined above. A free settling slope will be maintained on the active face until final excavation is complete. Warning signs are placed at the four corners of the excavation area. In the mining area, land disturbing activities are accomplished such that all Stormwater runoff are directed Into the mining pit. Drainage into the -southern mining pit (Mining Excavation Pit 3) drains north where it is pumped into Mining Excavation Pit 2. Mining Excavation Pit 2 gravity strains into Mining Excavation Pit 1. All water discharged from Mining Pit 1 gravity drains from the discharge of Mining Pit 1 and flows west along Cub Road. At the intersection of Cub Road and Bear Road, drainage is directed north and discharges from the property at the intersection of Bear Road and Gadwell'Road. Two surface drainage ditches drain the 1-1 PO—Gwn(yAT05220— aA OaM P4an%Paym*d pare Rogow pq Oau Plan—FinaL 10V?011 dx Dare County C&D Landfill Borrow Pit Operation and Maintenance Plan stockpile area. Sedimentation basins are constructed in each of the two ditches to treat stormwater and soil drainage. Based on pump curve data, it is estimated that the maximum discharge rate for the dewatering operation at the pit is approximately 1,206 gpm or 1.7 MGD- It is likely that discharge rates are typically lower than 1,200 gpm and vary based on head. Withdrawn water from the current excavation (Pit 3) is pumped to an adjacent pit and ultimately discharges to a series of canals on site, as described above. O&M Procedures The following sections discuss O&M procedures to be followed for the borrow pit activities at the site. A spreadsheet to be used as a weekly general inspection checklist has been generated based on the following activities. The weekly inspection checklist is provided as Table i. The weekly general inspection checklists will be maintained in a dedicated folder or file and kept in the scale house. In addition, as required in the Mining Permit, qualitative inspection and analytical discharge monitoring will be conducted at the outfall from Mining Pit 1 to the canal. A Stormwater Discharge Outfall (SDO) Qualitative Inspection Monitoring form is attached. The qualitative inspection monitoring form is to be completed weekly and during any storm event greater than 0.10 inches and will be kept on file in the scale house. If no discharge occurs during that period, the form should be filled out as "no flow." Pump Maintenance and Recording There is no meter present to monitor discharge rates from the borrow pit to the adjacent pit, however, there is an hour meter at the pump. Pumping rates vary -as head fluctuates, but the pump is never turned off. In the event of interruption or variation from the typical pumping rate and time, County staff shall record time that pump was not active and describe reason for inactivity on the weekly inspection checklist. Groundwater Monitoring I In order to monitor the effects of prolonged pumping of the surficial aquifer on the area surrounding the borrow pit, 4 new monitoring wells have been installed (Well-1 through Well-4). The wells were surveyed to State Plane coordinates and NAVD 88 elevation. Well locations are shown on the attached Wetland Flog Location Map. Water levels in the wells are to be measured from the top of the PVC casing quarterly. All water measurements shall be recorded on the corresponding weekly inspection checklist. Wetlands Monitoring The wetland areas adjacent to the borrow pit have been flagged and mapped (see attached Wetiond Flog Location Map). These areas and the adjacent ditches are to.be visually inspected for signs of vegetative stress or abnormality and water level/flow within the ditches on a weekly basis. All observations from the weekly wetland inspections shall be recorded on the weekly inspection form. t-2 P,7pa<e Canny-t793D8anow Pe 61u PlaroRr..ed Du* BWn Pa O&M Plan Flnal_=1204 i de Dare County C&D Landfill Borrow Pit Operation and Maintenance Plan Stormwater Qualitative Inspection Monitoring Stormwater qualitative inspection monitoring shall be conducted at the outfall from Mining Pit 1 weekly and during any storm event greater than 0.10 inches. Qualitative inspection monitoring shall include descriptions and observations made at the outfall and include: Color; odor; clarity; floating solids; suspended solids; foam; oil sheen; indications of sediment deposition; indications of erosion; and any other obvious indication bf stormwater pollution. If no discharge occurs for that period, the form shall be filled out as "no flow." All weekly qualitative inspections shall be recorded on the attached Stormwater Discharge Outfall (SDO) Qualitative Inspection Monitoring form and kept on file in the scale house. If obvious indications of turbidity, erosion or sedimentation are observed, perform maintenance as necessary. Stormwater Analytkal Monitoring Stormwater analytical monitoring shall be conducted at the outfall from Mining Pit 1 semi- annually during a representative storm event that causes discharge. Samples for Settleable Solids and Total Suspended Solids shall be collected and sent to an offsite laboratory for analysis. Field measurements of turbidity shall also be collected at the outfall during these events. Total Rainfall, Event Duration, and total Flow shall also be recorded on the Stormwater Discharge Outfall (SDO) Qualitative Inspection Monitoring form. Semi-annual analytical data and rainfall data will be recorded on a Discharge Monitoring Form and kept on file in the scale house. However, if any parameter benchmark is exceeded for a semi-annual event, a Stormwater Exceedence DMR form will be forwarded to the Regional DWQ office within 30 days of receipt of the analytical data. Analytical results for the semi-annual events will be compiled in an Annual Discharge Monitoring Form for submittal to the Central DWQ office by March 1 of the following year. Semi-annual stormwater samples shall be collected between January 1—June 30 and July 1— December 31, with a minimum of 60 days between samples. Mine Dewotering Discharge Analytical Monitoring In addition to the semi-annual stormwater monitoring, quarterly analytical sampling must be conducted at the outfall to monitor general effluent quality from the dewatering activities. Samples are to be collected and:analyzed for pH, Settleable Solids, Total Suspended Solids, and Turbidity. Total dewatering volume for the date -of sample collection must also be recorded. Pump volume can be estimated from pump hour recordings from Table i and' pump curves. Quarterly effluent analytical data will be recorded on a Discharge Monitoring Form acid will be kept on file in the scale house. However, if any parameter limit is exceeded, or a violation is found for any quarterly event, an Effluent Exceedence DMR form will be forwarded to the, Regional DWQ office.within 30 days of receipt of the analytical data.

Describe in detail the sequence of events for the development and operation of the mine and reference the sequence to the mine map(s). Attach additional sheets as needed. The existing excavation started approximately 150 feet south of the canal adjacent to Cub Road to minimize the effects of groundwater flow changes on the Construction & Demolitions (C&D) landfill groundwater monitoring system and has continued to be performed at an,average:of-1=8-20=feet=below-mean:sea,level (msl) extending south toward Grouse Road. A 25-foot buffer exists along the eastern woods line, which is approximately 295 feet from the County's property line. The southern extent of the excavation will not extend closer than 25 feet from the woods line south of Grouse Road, which is approximately 1,150 feet from the County's property line (See attached Sheet C-1). Excavation is performed in increments as necessary to supply base fill, daily cover, and cap construction for the C&D landfill. Dewatering of the excavation occurs as necessary and as defined in Sectiont31 . of this permit. Excavated material is temporarily stockpiled in the stockpile area and after adequate drainage, the soil is used at the C&D landfill site. ® During excavation the uppermost organic layer is stripped and stockpiled separately at the C&D landfill site for future use as final C&D landfill capping material to support grass covers. Due to the sandy nature of the material to be excavated a free settling slope is maintained on active excavation surfaces. Upon completion ® of excavation the final slopes for the outer slopes included in this modification will be 3.1 (H:V). All other existing slopes will be in accordance with the previous approved mining permit. After completion of the excavation for a major portion of the outer face, all above water table areas will be stabilized with vegetative cover in accordance with the most recent Vegetation Plan, which was provided in the approved Erosion and Sedimentation Control Plan for Phase 4 of the C&D landfill. A copy of the approved plan is included in Appendix A. In accordance with the previous approved mining permit as the final edges of the excavation pit are completed, excavation equipment operators will ensure that the final below water table surface slopes comply with the specifications outlined above. A free settling slope will be maintained on the active face until final excavation is complete. Warning signs will be placed at the four corners of the excavation area. 2. Describe specific erosion control measures to be installed prior to land disturbing activities and during mining to prevent offsite sedimentation (include specific plans for sediment and erosion control for mine excavation(s), waste piles, access/mine roads and process areas), and give a detailed sequence of installation and schedule for maintenance of the measures. Locate and label all sediment and erosion control measures on the mine map(s) and provide typical cross-sections/construction details of each measure. Engineering designs and calculations are required to justify the adequacy of any proposed measures. In the mining area, land disturbing activities are accomplished such that all stormwater runoff will be directed into the mining pit. Drainage into the southern mining pit (Mining Excavation Pit 3) will drain north where it is pumped into Mining Excavation Pit 2. Mining Excavation Pit 2 gravity drains into Mining Excavation Pit 1. For ultimate discharge from Mining Pit 1, see the discussion in Section 3.b. of this permit. Two surface drainage ditches drain the stockpile area. A sedimentation basin will- be constructed in each of the two ditches to treat stormwater and soil drainag�Disturbed areas that are subject to future disturbance will receive temporary seeding if the area remains exposed for more than 30 days.

Describe what kind of barricade will be used to prevent inadvertent public access along any high wall area and when it will be implemented. Vegetated earthen berms, appropriate fencing and adequate boulder barriers may be acceptable high wall barricades. A construction detail/cross-section and location of each type of barricade to be used must be indicated on the mine map(s). The site is located in a relatively remote area of mainland Dare County. The site is bounded on the east by U-S. Highway 264 and on the other three sides by the Alligator River National Wildlife Refuge. Access to the area is limited to Link Road and Cub Road. A gate is installed on Link Road at the western end of the bridge and is locked with a padlock when not in service. A similar gate is installed at the Cub Road entrance. A gate attendant house is located immediately inside the gate on the southern edge of Cub Road. The entrance is manned by the gate attendant at all times when the facility is open. Access from the western side of the C&D landfill is unlikely since all adjacent property is in the Wildlife Refuge and the nearest public access to the Refuge (other than Link Road) is approximately 5 miles away. ® However, a swinging padlocked gate at the western end of Link Road controls access to the western portions of the site. The gate belongs to the U.S. Fish and Wildlife Service and is locked at all times when not in use to prevent unauthorized access to the Refuge. A 0.75 inch steel cable attached to a two 4-inch diameter steel posts cemented into the ground controls access to the waste disposal area via Cub Road and the excavation service road. The steel cable is padlocked when not in use. The cable posts are installed at the bridge over the canal adjacent to Cub Road to prevent vehicles from bypassing the cable restriction. The excavation access road to the barrow pit area is chained off when not in use.

Are acid producing minerals or soils present? Yes ❑ No M. If yes, how will acid water pollution from the excavation, stockpiles and waste areas be controlled? Although surface water in the area is generally acidic, the acidity is due to the decomposition of surface organic material. Typically, the Albermarle-Pamlico peninsula has a stratified groundwater regime. Subsurface aquifers that are separated from the uppermost groundwater layer by relatively impervious materials are not acidic, and in fact, are alkaline due to limestone deposits. Any excavations that penetrate the subsurface aquifers can potentially fill with non -acidic water. pH readings taken from the existing borrow pit excavation indicate that the pond resulting from the proposed excavation area will be neutral to alkaline. ® 10. a. Describe specific plans (including a schedule of implementation) for screening the operation from public view such as maintaining or planting trees, bushes or other vegetation, building berms or other measures. Show the location of all visual screening on the mine maps) and provide cross -sections through all proposed berms or proposed spacing, sizes and species for tree plantings. ® The site is located in a relatively remote area of Dare County. The site is currently shielded on the east, north, ® and south by a barrier of natural trees and undergrowth that is at a minimum approximately 270 feet thick. These natural tree barriers are on the existing C&D1`a7MJfil1 site owned by Dare County, and are maintained by the County as a site barrier to the entire C&D landfill property. Beyond this existing tree sight barrier the site is buffered and shielded by the Alligator River National Wildlife Refuge on the north, west, and south. Public view of the site is limited along U.S. Highway 264 by the eastern tree line sight barrier (270 feet minimum) except at the Link Road access point. 0' 0 b. Could the operation have a significantly adverse effect on the purposes of a publicly owned park, forest or recreation area? If so, how will such effects (i.e., noise, visibility, etc.) be mitigated? 0 -9- 0 a APPLICATION FOR A MINING PERMIT The existing borrow area has been in operation since 1995 to provide the C&D landfill soil material requirements. Proposed borrow operations are identical to those employed since that time. Consequently, no significant adverse effect on the purposes of a publicly owned park, forest, or recreational area is expected from the proposed borrow pit expansion. In addition to the -current landfill operations, the site also supports a County Shooting Range and model aircraft flight area: Cleared areas not currently in use for landfill activities are under cultivation as are portions of the U.S. Fish and Wildlife property. Since these same operations have been ongoing since 1995 no adverse effects are anticipated from continuation of the same operations. Current mitigation measures are described below. A water truck mitigates dust. The borrow pit operation is buffered from the remainder of the site by the landfill operation and by the agricultural activities on the rest of the County's site. These activities have been underway since 1995 and are similar to those proposed for future site use. Litter control will be provided by: -Maintaining the smallest usable working face surface area -Deploying litter fences and potable lifter screens as necessary -Requiring all waste hauling vehicles entering the site to have in place adequate covers for containment -Routinely policing the site and U.S. Highway 264 in the vicinity of the site Will explosives be used?

Purpose To temporarily stabilize denuded areas that will not be brought to final grade for a period of more than-21 calendar days. Temporary seeding controls runoff and erosion until permanent vegetation or other erosion control measures can be established. In addition, it provides residue for soil protection and seedbed preparation, and reduces problems of mud and dust production from bare soil surfaces during construction. Conditions Where On any cleared, unvegetated, or sparsely vegetated soil surface where Practice Applies vegetative cover is needed for less than I year. Applications of this practice include diversions, dams, temporary sediment basins, temporary road banks, and topsoil stockpiles. Planning Annual plants, which sprout and grow rapidly and survive for only one season, Considerations are suitable for establishing initial or temporary vegetative cover. Temporary seeding preserves the integrity of earthen sediment control structures such as dikes, diversions, and the banks of dams and sediment basins. It can also reduce the amount of maintenance associated with these devices. For example, the frequency of sediment basin cleanouts will be reduced if watershed areas, outside the active construction zone, are stabilized. Proper seedbed preparation, selection of appropriate species, and use o€quality 'seed are as important in this Practice as in Practice 6.11, Permanent Seeding. Failure to follow established guidelines and recommendations carefully may result in an inadequate or short-lived stand of vegetation that will not control erosion. Temporary seeding provides protection for no more than I year, during which time permanent stabilization should be initiated. Specifications Complete grading before preparing seedbeds, and install all necessary erosion control practices such as, dikes, waterways, and basins. Minimize steep slopes because they make seedbed preparation difficult and increase the erosion hazard. If soils become compacted during grading, loosen them to a depth of 6-8 inches using a ripper, harrow, or chisel plow. SEEDBED PREPARATION Good seedbed -prepam— ion is essential to successful plant establishment. A good seedbed is well -pulverized, loose, and uniform. Where hydroseeding methods are used, the surface may be left with a more irregular surface of large clods and stones. Liming —Apply I ime accordingto soil test recommendations. IfthepH (acidity) of the soil is not known, an application of ground agricultural limestone at the Rev. 6106 6.10. l Q 0 0 A 0 0 0 0 0 O 0 0 0 0 0 6.10.2 0 rate of i to 1 1/2 tons/acre on coarse -textured soils and 2-3 tons/acre on fine - textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed. Fertilizer —Base application rates on soil tests. When these are not possible, apply a 10-I0-10 grade fertilizer at700-1,000lb/acre. Both fertilizerand lime should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more than 30 minutes before application. Surface roughening —If recent tillage operations have resulted in a loose surface, additional roughening may not be required, except. to break up large clods. If rainfall causes the surface to become sealed or crusted, loosen it just prior to seeding by disking, raking, harrowing, or other suitable methods. Groove or furrow slopes steeper than 3: t on the contour .before seeding (Practice 6.03, Surface Roughening). PLAINT SELECTION Select an appropriate species or species mixture from Table 6. l0a for seeding in late winter and early spring, Table 6.1Ob for summer, and Table 6.1 Oc for fall. In the Mountains, December and January seedings have poor chances of success. When it is necessary to plant at these times, use recommendations for fall and a securely tacked mulch. SEEDING Evenly apply seed using a cyclone seeder (broadcast), drill, cultipacker seeder, or hydroseeder. Use seeding rates given in Tables 6.10a-6.10c. Broadcast seeding and hydroseeding are appropriate for steep slopes where equipment cannot be driven. Hand broadcasting is not recommended because of the difficulty in achieving a uniform distribution. Small grains should be planted no more than I inch deep, and grasses and legumes no more than 1/2 inch. Broadcast seed must be covered by raking or chain dragging, and then lightly firmed with a roller or cultipacker. Hydroseeded mixtures should include a wood fiber (cellulose) mulch. MULCHING The use of an appropriate mulch will help ensure establishment under normal conditions, and is essential to seeding success under harsh site conditions (Practice 6.14, Mulching). Harsh site conditions include: - seeding in fall -for winter cover (wood fiber mulches are not considered adequate foe this use), • slopes steeper than 3:1, • excessively hot or dry weather, • adverse soils (shallow, rocky, or high in clay or sand), and • areas receiving concentrated flow. If the area to be mulched is subject to concentrated waterftow, as in channels, anchor mulch with netting (Practice 6.14, Mulching). Practice Standards and Specifications Maintenance Reseed and mulch areas where seedling emergence is poor, or where erosion occurs, as soon as possible. Do not mow. Protect from traffic as much as possible.

Introduction Duringtheinitialphaseofallland disturbing projects, theprotectivelayer,cither natural or man-made, is removed from the earth's surface. As the protective layer is removed, the resulting bare areas are exposed to the natural forces of rainfall, freezing, thawing, and wind. The result is soil erosion that leads to sediment pollution of North Carolina streams, rivers, lakes, and estuaries. This design manual presents many alternative strategies for preventing erosion and reducing sediment loss during the construction process. Establishment of protective vegetative cover during the construction project, however, is the crucial step in achieving soil stabilization, controlling soil erosion, and preventing sedimentation of waterways. Without asutfiicient amount of root mat and leaf cover to protect and hold the soil in place, large volumes of soil will be lost and waterways wil l be degraded long after projects are considered complete. Sections of this practice standard address many of these various situations and set forth selection criteria for the appropriate cover based on purpose and adaptability. Some sediment and erosion control practices recommended in earlier editions of the manual may no longer be applicable, For example, many popular and commonly used seed and plant varieties have been identified as invasive. Invasive plants are defined as species that aggressively compete with, and displace, locally adapted native plant communities. In select cases where no practical alternative is available, these plants may be considered on a limited basis for soil stabilization, understanding that the goal is to eliminate the use of all invasive plants in favor of non-invasive native and/or introduced species that will pLq) dean equally acceptable vegetative cover. Where there is no alternative to the use of invasive species, measures need to be incorporated in the installation and maintenance of these plants to limit their impacts. Rev. 5/08 6.11.1 0 It is imperative that disturbed soils be totally protected from erosion and sediment loss during construction and before a project is considered complete and acceptable. Installing appropriate vegetation in an immediate and timely fashion is the optimal means of achieving this stabilization. Vegetative specifications for most exposed soil conditions across North Carolina are provided in this section of the manual. It should be noted however, that no two sites in the State are exactly alike; therefore the protective vegetative'cover for individual sites should be carefully, selected. Each requires its own investigation, analysis, design and vegetative prescription as set forth in this section of the manual. This practice standard describes three stages of vegetative cover; immediate, primary and long term. Effective and acceptable stabilization can be provided only when the optimum combination of immediate, primary, and long term vegetative practices are applied. The vegetative measures presented in this chapter include application of seed, sod and sprigs. Use of field and container grown plants are not addressed in this manual. Planting of these types of vegetation is typically at spacing and intervals that will not provide the required protective cover. However, the design professional is encouraged to utilize these larger plants 'to compliment the required protective cover, particularly where these types of plants will provide seed for continued long term cover and wildlife habitat. PLANNING CONSIDERATIONS SOILS Test and analyze the type(s) and quality of the existing soils on a site, their pH ranges, and their nutrient levels. Taking soil samples from the different areas of the project site and having them tested at a state or independent lab will provide a baseline for determining the pH modifiers and additional nutrients required for the selected plant varieties. Disturbed conditions on a site may produce a variety of soil communities. Nutrient and pH levels in deeply cut soils will be quite different from those soils found on the original surface. When sites are highly disturbed through mechanical means such as grading, the soils become mixed together in many different ratios. These areas should be identified and tested. Results from soil tests will usually include recommended application rates of soil modifiers such as lime and fertilizer for the selected plant species in the particular soils. Application rates will be itemized in the report. The texture of the soil on a site, which is the proportion of sand, silt, and clay in the soil, is an important physical indicator of the site's ability to support vegetation. In heavy clay soils amendments may be necessary to provide an adequately drained planting medium. Conversely, in extremely sandy soils, amendments may be required to provide for moisture and nutrient retention. 6.11.2 Rev. 5/08 Practice Standards and Specifications Soil tests will indicate the texture of the given soil but will not provide recommendations for amendments that' will improve the soil texture. Generally, the addition of organic materials will improve the porosity of heavy clay soils and improve the water holding capacity of extremely sandy soils. On sites where these different soil conditions exist, it is recommended that a design professional with experience in soil modification be employed to recommend the proper amendments. For more information visit the NCDA Agronomic Services Soil Testing web page http://www.agr,state.nc.us/agronornic/sthome.htm SOIL PREPARATION Proper soil preparation is necessary for successful seed germination and root establishment. It is also necessary for establishment of rooted sprigs, sod and woody plants. Heavily compacted soils prevent air, nutrients and moisture from reaching roots thereby retarding or preventing plant growth. The success of site stabilization and reduction of future maintenance are dependent on an adequately prepared soil bed. Following are the requirements for preparation of areas to be vegetated by grassing, sprigging, sodding, and/or planting of woody plants: General Requirements: • Preparation for primary/permanent stabilization shall not begin until all construction and utility work within the preparation area is complete. However, it may be necessary to prepare for nurse crops prior to completion of construction and installation of utilities. • A North Carolina Department of Agriculture Soils. Test (or equal) shall be obtained for all areas to be seeded, sprigged, sodded or planted. Recommended fertilizer and pH adjusting products shall be incorporated into the prepared areas and backfill material per the test. • All areas to be seeded or planted shall be ti l led or ripped to a depth specified on the approved plans, construction sequence and/or construction bid list. Ripping consists of creating fissures in a criss-cross pattern over the entire surface area, utilizing an implement that will not glaze the side walls of the fissures. Site preparation that does not comply with these documents shall not.be acceptable. The depth of soil preparation may be established as a range based on the approval of the reviewing state or local agency. Once tilled or ripped according to the approved plan, all areas are to be returned to the approved final grade, pH modifiers and/or other soil amendments'specified in the soil tests can be added during the soil preparation procedure or as described below. • All stones larger than three (3) inches on any side, sticks, roots, and other extraneous materials that surface during the bed preparation shall be removed. -- Rev. 5108 6.11.3 0 Areas to be Seeded: • Till or disc the prepared areas to be seeded to a minimum depth of four (4) inches. Remove stones larger than three (3) inches on any side, sticks, roots and other extraneous materials that surface. If not incorporated during the soil preparation process, add pH modifier and fertilizers at the rate specified in the soil test report. • Re -compact the area utilizing a cultipacker roller. The finished grade shall be a smooth even soil surface with a loose, uniformly fine texture. All ridges and depressions shall be removed and filled to provide the approved surface drainage. Seeding of graded areas is to be done immediately after finished grades are obtained and seedbed preparation is completed, Areas to be Sprigged, Sodded, and/or Planted: • At the time of planting till or disc the prepared areas to a depth of four (4) to six (6) inches below the approved finished grade. Remove all stones larger than three (3) inches on any side, sticks, roots and other extraneous materials that surface. If not incorporated in the ripping process, add pH modifier, fertilizer, and other recommended soil amendments. • Re -compact the area utilizing a cultipacker roller and prepare final grades as described above. Install sprigs, sod and plants as directed immediately after fine grading is complete. Mulch, mat and/or tack as specified. VEGETATION Availability of seed and plant materials is an important consideration of any construction stabilization effort. Throughout North Carolina, climate, economics, construction schedule delays and accelerations, and other factors present difficult challenges in specifying the different vegetation needed for site stabilization. To help resolve this issue, vegetative stabilization requires consideration in three categories: ■ Immediate Stabilization —nurse crop varieties (Note: temporary mulching may be utilized for immediate stabilization if outlined on the approved plans and construction sequence.) ■ Primary Stabilization — plant varieties providing cover up to 3 years with a specified maintenance program ■ Long Term Stabilization — plant varieties providing protective cover with maintenance levels selected by the owner An adequate job in one of these areas does not guarantee success in the later phases. Horticultural maintenance must be included in the plans. Immediate vegetative cover will always require additional fertilization, soil amendments, -soil aes:sg&verseeding and/or other horticultural maintenance until primary vegetative cover is established. 6.11.4 Rev. 5/08 Practice Standards and Specifications Where provisions are made for regular maintenance, primary vegetative cover may be the end result. An example of primary vegetative cover being acceptable as an end use would be lawns in residential and commercial developments that are established, monitored and complimented with regular and approved horticultural maintenance practices. (See Example 6.1 La.) In projects where continual maintenance will not be provided or scheduled following the primary stabilization of a project, long-term stabilization will be necessary. Maintenance of initial and long-term stabilization can cease only after the long-term cover has established and hardened to local climatic conditions. Maintenance of long-term vegetation must be included in the project construction sequence and on the approved plans. Examples of areas suitable for long term vegetation include roadsides, reforestation areas, restored flood plains, restored riparian areas, phased closing of landfills, and mining reclamations. Complete stabilization requires using at least two, and most times, all three vegetative phases. The design professional must clearly communicate this point in their specifications, construction sequence, and in direct communications to owners and installers. The charts in tables 6.1La through 6.1l,d provide information to assist the design professional in this task. The tables are not inclusive and are presented only as alternatives. The professional is expected and required to provide design and specifications that combine the information in the manual with knowledge of the particular sites and their constraints. pH AND NUTRIENT AMENDMENTS Determining the nutrients that enable seed and container plants to grow, flourish, and become established after planting are critical elements of the design and stabilization process. The soils tests previously described will provide a 'recipe for amendments based on particular plants and particular soils. The test results will recommend the amounts of base elements (nitrogen, phosphorous, potassium), pH modifiers and other trace elements that should to be added to the soil for selected species of seeds and plants. The acidibase characteristic of the soil is a primary component of soil fertility. If the soil acidity is not in the proper range, other nutrients will be ineffective, resulting in less productive plant growth. Most plants grow best in a pH range of 6.5 — 7.6 (slightly acidic to neutral). The soil tests will recommend the specific amendments and application rates required to achieve this range. These amendments must be incorporated into the soil (not applied on the surface) to be effective. (See the General Requirements for soil preparation specifications and timing for incorporation of soil amendments.) The base elements are easily found in bulk quantities. Lime can also be obtained in large quantities. They all must be thoroughly incorporated into the soil through appropriate mechanical means. Ground surface applications without proper soil mixing will result in poor results. In addition to the base fertilizers, other trace elements are needed to produce healthy and vigorous growth. These include but may not be limited to sulfur, manganese, zinc, boron, chlorine and molybdenum. If not already included with bulk mixes of the base elements, they can be obtained from commercial suppliers. Rev. 5108 6.11.5 Provisions for soils test during and/or after initial grading is complete shall be included on the approved plan, in the approved construction sequence, and on the bid item list utilized for the project. If yoea did not obtain a soil lest: Follow these recommendations for all grasses except centipedegrass. 1. Apply 75 pounds of ground limestone per 1,000 sq. ft. 2. Apply a starter type fertilizer (one that is high in phosphorus) based on the type of grass and planting method. Fertilizer bags have a three -number system indicating the primary nutrients, such as 8-8-8 or 5-10-10. These numbers denote the N-P-K ratio —the percentage of each nutrient in a fertilizer. The ® percentages are always noted in the following order: N Nitrogen for green color and growth. P2O5 Phosphorus for good establishment and rooting. K2O Potassium to enhance pest and environmental stress tolerance. ® Some common examples of starter type fertilizers required for a 1,000 sq. ft. area include 40 pounds of 5-10-10, 20 pounds of 10-20-20, or 16 pounds of 18-24-6. For sandy soils, typical to coastal plain and sandhills of North Carolina, fertilizer rates should be increased by 20 percent. © Where available, it is recommended that the design professional specify organic compounds that meet the fertilization requirements, pH and other ® element requirements. Initial studies have indicated that these compounds have a more positive effect on the environment than some of the synthetic compounds used to manufacture inorganic fertilizers. These materials are readily available in the commercial trade as well as found in recycled yard waste debris, sewerage sludge, lime -stabilized sludge and animal manures. ® Materials proposed for use must be industry certified and/or privately tested and certified to be acceptable for proposed areas of use and application prior to approval. ® MULCHES AND TACKING AGENTS Mulches and tacking agents may be required or necessary to protect a seedbed's disturbed surface until the seed can germinate and provide the required protection from erosion. Selection of the materials used in this application should be based on their ability to hold moisture in the soil, as well as protect ® exposed soil from rainfall, storm water runoff, and wind. The availability of ® the selected material and the means to apply it are critical factors to consider when planning for the stabilization of any disturbed area. The mulch must cover a minimum of eighty (80) percent of the soil surface and must be secured ® by a tacking agent, crimping, or protective biodegradable netting. Netting that incorporates plastic mesh and/or plastic twine should not be used in wetlands, riparian buffers or floodplains due to the potential of small animal mortality. See Section 6.14 for detailed specifications and product applications. SOIL BLANKETS ® Soil blankets can be an acceptable and effective method of temporary sediment and erosion controC-'inn7 u of nurse crops. See Section 6.17 of the manual for descriptions of this product and how it can be used in conjunction with this section. In absence of mulches and tracking agents other means of protection may be necessary and required. ® 6.11.6 Rev.5/08 Practice Standards and Specifications PROTECTIVE MATTING Protective matting consists of an impervious cover secured to the soil surface in lieu of vegetative cover. It is used to protect and stabilize the surface where the process of seeding or planting forms of vegetation may cause more erosion and off -site sedimentation than application of the mat. It is also used where a disturbed area is intended to lay fallow for a period of time before additional construction or land disturbance takes place. If a pervious matting is selected, a combination of vegetation and matting is required. Seeds can be applied prior to installation of the matting only after proper seedbed preparation has been provided. Also, live stakes, dormant sprigs, and other vegetation forms can be inserted in the pervious matting once it has been installed. Pre - seeded pervious matting may be used for quicker root establishment and stabilization only if certified dating and germination guarantees are provided. The reviewing agency must approve all pre -seeded matting on site prior to installation. Matting that incorporates plastic mesh and/or plastic twine should not be used in wetlands, riparian buffers or floodplains due to the potential of small animal mortality: See Section 6.17 for detailed specifications and recommended product applications. STABILIZATION IN WETLANDS, RIPARIAN BUFFERS, AND FLOODPLAINS Land disturbing activity involving streams, wetlands or other waterbodies may also require permitting by the U.S. Army Corps of Engineers or the N.C. Division of Water Quality. Approval of an erosion and sedimentation control plan is conditioned upon the applicant's compliance with federal and State water quality laws, regulations, and rules. Additionally, a draft plan should be disapproved if implementation of the plan would result in a violation of rules adopted by the Environmental Management Commission to protect riparian buffers along surface waters. Care should be taken in selecting vegetative stabilization of wetlands and riparian buffers to comply with permitting requirements of other agencies, as well as provide adequate ground cover, Planning Considerations for Land Disturbing Activities Within Wetland, Riparian, and Floodplain Areas Wetlands, riparian areas, floodplains, and/or terrestrial areas between streams and uplands, serve to buffer surface water and provide habitat for aquatic and terrestrial flora and fauna. When cleared and disturbed, these sensitive areas are difficult to protect. Because of their proximity to water courses, relatively high ground water tables, and flooding potential, detailed analysis and design is necessary to determine the appropriate erosion control measures during construction. Determining the appropriate and most expeditious means of permanent vegetative stabilization in these areas requires equally detailed analysis and design. The following considerations for erosion control and stabilization should be taken into account during the design phase of the land disturbing project,whgje sensitive areas are involved: • Obtain soil tests to determine the soil type, pH, texture and available nutrients. • Based on the soil tests provide a schedule of nutrients and other soil amendments that will be required. Rev. 5108 6.11.7 6❑ • Select a seeding mix of non:invasive species that will provide immediate stabilization (a short-term environment that will support and compliment permanent vegetative stabilization) and include a selective native species mix that will eventually provide a permanent cover (a long-term environment that, with minimal maintenance, will provide adequate root and leaf cover). • Invasive species are to be avoided. If native species and introduced non- invasive seed sources are not available, protective matting that will hold and foster the development of native cover from adjacent seed sources should be used. Continuous maintenance must be employed until the selected species have matured and areno longer susceptible to competition from invasive plants. If no alternative to the use of invasive seeds and plants is available, invasives approved on the plans may be utilized only with strict containment measures outlined in detail on the plans, in the construction sequence and in the maintenance specifications. • A quickly germinating nurse crop of non-invasive, non-competitive annual grass species can be used along with native seeding and/or matting. These temporary systems should be planted at minimal density so that they do not inhibit the growth and establishment of the permanent, native species. (See the plant chart in Table 6.11.a for recommended native and nurse crop species.) • Seedbed preparation is key to successful establishment of seeds. Particular care should be taken, however, when working in wetlands, riparian areas, or floodplains due to their sensitive nature. Careful consideration should be given to.the types and placement of large equipment working in these areas. This process must be outlined in detail on the plan's construction sequence. • Installation techniques vary and should be planned for accordingly. • A maintenance plan must be established for optimal plant establishment, submitted with the plans and included in the bid list for the project. Like all construction sites, wetlands, riparian areas, and floodplains will vary widely in physical makeup across North Carolina. Different conditions will dictate specific treatment, design and plant selection within the Mountains, Piedmont, and Coastal Plain regions. Soil tests, seedbed preparation, mulching, matting, and maintenance will be critical for successful vegetative establishment and long-term protection of these environmentally sensitive areas. Unavoidable impacts to these areas during land disturbing activities need to be addressed in detail on the plan sheets and construction sequence. 6.11.8 Rev. 5108 Practice Standards and Specifications Native Seed and Plant Selection.for Stabilization of Wetlands, Riparian Amos, and Floodplains 4�` � g t•tpon the completion of the land disturbing activity, vegetative cover must be established on all areas not stabilized by other means.

The goal is to protect these �4e e Q areas from erosion and to prevent sedimentation of adjacent streams, wetlands, (�' 1 X,1 5 5 t lakes, and other water bodies. r• [} Planning considerations for wetlands, riparian areas and floodplains will require additional research, detail and specifications. Native grasses arc usually required as a condition of a 401 Water Quality Certification or a trout o buffer variance. Native vegetative species are plant species that naturally occur in the region in �C y • which they evolved. These plants are adapted to local soil types and climatic �1p variations. Because most native species do not germinate and establish as readily as some introduced species, it is necessary to provide anon -native nurse crop or matting to stabilize the soil until the native crop can become established as the dominant cover. Once established, the native plants will produce an extensive root structure that, if properly maintained, will stabilize soils and reduce erosive forces of rainfall and overland stormwater flow. Many of these plants also possess characteristics that, when established, allow them not only to survive, but also to thrive under local conditions. Rev. 5105 Seeding a mixture of perennial native grasses, rushes, and sedges is a way to establish permanent ground cover within wetlands, riparian areas and floodplains. The use of propagated plants is another method of reestablishing natives in these environments. Selecting a seed mixture and/or propagated plants of different species with complimentary characteristics will provide vegetation to fill select niches on sites with varying 'physical conditions. The design professional should note that because most native species do not germinate and establish as readily as some introduced species, it is necessary to provide a non-native nurse crop or matting to stabilize the soil until the native crop can become established as the dominant cover. For additional information about acceptable nurse crop varieties, consult the planting list in Appendix 8.02, local seed and plant suppliers, the North Carolina Cooperdtive Extension Service or a qualified design professional to assure the proper selection and plant mix. (. t l.9 0 Permanent native seed species within the seed mixture should be' selected based on natural occurrence of each species in the project site area. Climate, soils, topography, and aspect are major factors affecting the suitability of plants fora particular site and these factors vary widely across North Carolina, with the most significant contrasts occurring among the three major physiographic regions of the state — Mountains, Piedmont, and Coastal Plain. Sub -regions of the state should also be considered. For example, the Triassic Basin in the Piedmont region may have characteristics that call for special soil treatment, limited -plant selection, and special maintenance. Even. within the riparian area, there may be need for different species depending on site conditions (i.e., dry sandy alluvial ftoodplains with wet pockets). Therefore, thoughtful planning is required when selecting species for individual sites in order to maximize successful vegetation establishment. Native seed and plant species are included on the plant list in Appendix 8.02 of this manual. The design professional should note that regardless of the benefits and advantages of native seeds and plants, there are potential issues if proper planning, installation and maintenance do not occur. These may include: • Potential for erosion or washout during the establishment stage; • Seasonal limitation on suitable seeding dates and availability of seed and ,plants; • Adaptability of species at specific sites; • Availability of water and appropriate temperatures during germination and early growth; and • Lack of maintenance to control invasive plants and undesirable competition. PLANTING • Seed —Prepare the seed bed as described above in soil preparation. Apply seed at rates specified on the plans, and/or as recommended in Tables 6.1la-c of this manual, with a cyclone seeder, prop type spreader, drill, or hydroseeder on and/or into the prepared bed. Incorporate the seed into the seed bed as specified. Provide finished grades as specified on the approved plan and carefully culti-pack the seedbed as terrain allows. If terrain does not allow for the use of a cultipacker, the approved plans and construction sequence must provide an alternative method of lightly compacting the soil. Mulch immediately. • Sprigs and Sod — Install onto the prepared seed bed per the most current guidance in Carolina Lawns, NCSU Extension Bulletin AG-69, or Practice 6.12 Sodding:.. 6.11.10 Rev. 5108 Practice Standards and Specifications Woody plants (liners, container, B&B) — These materials are typically used to complement an herbaceous protective cover. They eventually are major components of long-term, permanent stabilization and should be chosen and planned in conjunction with immediate and long-term maintenance. The plants should be selected and specified by the design professional for each individual project. See Practice 6.13 Trees, Shrubs, Fines, and Ground Covers. MAINTENANCE The absence of or an incomplete landscape management specification and/ or complete maintenance schedule shall constitute grounds for disapproval of the plans. Proper maintenance is critical for the continued stabilization once vegetative cover is established. Although maintenahce strategies for different sites may be similar, no two construction sites in North Carolina have been or will be able to be controlled or protected in identical ways. Variations in climate, topography, soils, available moisture, size and many other conditions will dictate the maintenance methodology to be used. A detailed schedule of maintenance will be required on the plans. This schedule will illustrate how the initial planting will be maintained to assure immediate, short term and permanent protection. The schedule will address topics such as appropriate irrigation of plants during the early establishment phase, drought conditions, excessive rainfall, mulch replacement, supplemental seeding, supplemental soils tests, application of nutrients and amendments, control of competitive and invasive species, disease and insect control, and corrective maintenance, measures to address failure of vegetation to become established. Contractual responsibility for maintenance after initial establishment of vegetative cover will be provided on the plans, in the construction sequence and on the bid list for the project. Maintenance bonds and/or warranty guarantee maybe required of the responsible party, especially for areas in or adjacent to environmentally sensitive sites such as wetlands, riparian buffers, floodplains, and waters of the State. See Example 6.11a for a sample maintenance specification and a minimum maintenance check list that shall be provided on all plans. RECOMMENDED BID LIST (These items should be itemized on documents utilized to obtain pricing for planting pertaining to vegetative stabilization of land disturbing projects in North Carolina.) • Soil test prior to grading (price per each test). • Soil test during grading operations (price per each test). • Soil test at completion of grading and/or prior to seeding, sprigging, sodding and application of fertilizer, lime, and other soil amendments (price per each test). • Ripping/subsoiling to a depth of six (6) inches.

SEEDING RECOMMENDATIONS The following _tables list herbaceous plants recommended for use as nurse crops for immediate stabilization and primary crops for initial and long-term stabilization. Nurse crops are expected to develop in two to five weeks and, with adequate maintenance, be an effective method of soil stabilization for a period of six months to one year. Nurse crops are not effective as primary long-term cover, however if properly maintained they can be an adequate cover and protection for the development of primary crops. The goal for a primary crop is for it to develop over a three-week to one-year period and be effective up to three years with a well-defined maintenance program. The long-term goal for a primary crop is the initial step toward a sustainable protective cover without the need of maintenance. Where the primary crop is intended for a managed lawn' and landscape aesthetics, the effective period can be extended by a more intense maintenance program. Where native species are utilized and become established during the planned maintenance program, a permanent cover that will support future succession species should exist and require little or no additional maintenance or management. In uses of both nurse and primary crops, the development periods listed on the tables are optimal based on normal climatic conditions for the planting dates listed. The sediment and erosion control maintenance program must recognize that optimum temperatures and rainfall are the exception rather than the rule. The design professional needs to provide flexibility in the stabilization plan to address the potential ranges of temperature -and moisture conditions we experience in North Carolina. 6.11.12 Rev. 5108 Practice Standards and Specifications Information is provided for seeding rates, optimum planting dates in the state's three regions, sun and shade tolerance, invasive characteristics, compatibility in wetlands and riparian buffers, and installation maintenance considerations. By going through the lists the design professional can select the nurse and primary seed varieties and maintenance characteristics they feel are best suited for their site conditions, vegetation management expertise and maintenance capabilities. To use the information in the seeding charts the plan preparer must: • Determine what nurse crop best fits their site, soil conditions, and permanent seed mix. • Obtain soil tests for all areas to be seeded. • Know the site's region: mountains, piedmont, or coastal plain. • Know if the areas to be seeded are sunny, part shade, or full shade. • Know if the areas are well or poorly drained. • Know if wetlands or riparian buffers are included in the areas to be seeded. • Know if a chosen crop is invasive and if so, what potential impacts it will have on the site and adjacent properties. With this knowledge the plan preparation may proceed utilizing the charts provided to provide the several seed mixes that will be applicable to the. different areas requiring stabilization.

NOTE: With the native varieties, the seed mix should be in-the�r4�nge of 15 pounds per acre. Depending on availability of native seeds adaptable to North Carolina, the percentage of a particular variety used may be reduced or increased accordingly. Although diversity is desirable, it is imperative that the primary crop develop and become an effective protective cover. In addition to the native species mix, additional nurse crop species must be included to provide immediate stabilization and an adequate ground cover. Rev. 5/08 6.11.19 0 Example 6.1 La GUIDELINES FOR WRITING MINIMUM LANDSCAPE MANAGEMENT SPECIFICATIONS Following is an outline that demonstrates what should be included in specifications that will insure the long term stabilization of disturbed sites in North Carolina. As noted before in this manual, each construction site in the state is unique and has features that will require special provisions for revegetation and stabilization. The outline provided below cannot address these individual sites. It is the responsibility of the design professional and the financially responsible party to see that the specifications are edited to fit their site and to assure that permanent stabilization is achieved. General Provisions A. Intent: 1. These specifications are prepared with the intent of promoting outstanding performance in long- term stabilization. They are to be used as guidelines in establishing sediment control and vegetative standards for the sites. Final technical decisions such as herbicides, fertilizer ratios, times of application and schedules are to be determined by the Contractor, who has the responsibility to obtain soil test and to manage the vegetation to achieve the desired results. The maintenance specifications must address maintenance for sediment and erosion control vegetation during construction and for permanent/long-term stabilization. B. Description of Work: 1. Perform all work necessary and required for the (insert period of contract) maintenance of the project as indicated on the drawings, in the project manual, and specified herein. 2. Licensing: a) Contractor shall provide verification of current, applicable pesticide applicator licensing for each applicator that will handle pesticides on the contracted sites. 3. Contract Administration a) Staffing: The Contractor shall provide adequate staffing, with the appropriate expertise, to perform all required work. b) Monthly Site Review meetings will be held. Attendees will include the Contractor's Project Manager and Site Foreman and the property manager or other representative designated by the financially responsible party. Result of site reviews will be documented and circulated to the attendees and the owner by the contractor. c) The Contractor will communicate with the proper person on a monthly basis to summarize work performed and immediately notify the project manager of any failure of the site to remain stabilized. I1. Materials A. Soil Additives: Additives are to be applied per soils test taken prior to, during and after construction. (Use this section to provide the types and quantities of fertijimg S, lime, and other soil amendments called for in the soils report. Include all soils test reports in the specifications document. This narrative or list should include quantities, rates, mixes, organic information, manufacturer, sources, and other information suggested in the soils test.) 6.11.20 Rev. 5/08 ti Practice Standards and Specifications A. Pesticides: I. Establish an integrated Pest Management (IPM) program for the site that relies on targeted insect and disease control coupled with sound stabilization management and water management practices. . 2. These specifications do not include pesticide treatments for infestations of Southern Pine Beetle, Gypsy Moth, or Fire Ants. The contractor shall notify the Owner if these pests are observed on site. 3. All pesticides shall be applied by a North Carolina licensed applicator in accordance with all State and Federal regulations and per manufacturer's recommendations. B.-Mulches: Mulch for areas not subject to erosion and over wash by storm water should be called out in this section addressing its maintenance, replacement, removal and conversion to other uses. Those subject to erosion and over wash by storm water must be addressed on the plans and in the calculations. . III. Execution A. General: 1. Good long tern stabilization is based on the proper maintenance, management and balance of nutrients, soil moisture and general cultural practices. It is recognized that fewer fungicide and pesticide treatments as well as lower fertility rates are required with a well managed, balanced landscape. The following section is meant to promote this balance and therefore do not highlight specific quantitative standards. (Quantitative standards should be addressed as site specific by the design professional in conjunction with the owner and contractor.) Calendar references are general and are to be used only as a guide. Weather and soil conditions that are most appropriate for a given process, procedure and/or area of the state shall be the determining factor in scheduling work. B. Soil Tests: 1. After the soil test prior to stabilization, tests shall be made yearly in the fall to determine the required soil additives for all stabilized areas. If known nitrogen requirements are not specified by previous test, they need to be determined by the subsequent soils test and the proper applications made. Fertilizer ratios may be determined through analysis of the soil tests coupled with the contractor's experience and knowledge of the site. C. Mowing 1. Mowing for maintained turf/lawns a. Mow areas intended for "groomed appearance" on a schedule during the growing season and as required throughout the year to provide the desired appearance. (Establish a mowing frequency here thataddresses the specific plant species used and their growing habits.) This frequency will be a minimum standard. Particular properties and their peculiar characteristics as well as individual plant species may require mowing more often than the stated minimum may be required. This should be noted in this section. b. The range of turf species suggested for lawns in the three growing regions of North Carolina vary as to optimum maintained height. The selected species should be maintained at a height recommended by the seed producer: Do not cut too short and do not allow the turf to attain a height that will cause the crop to decline or die. Consult individual seed producers and/or packaging for recommended mowing heights. c. Mow with a mulching mower to limit the amount of clippings removed, or mow and blow in such a manner that clippings are not evident and not to adversely effect the growing capacity Rev. 5/08 6.11.21 0 and/or health of the existing vegetation turf. It•is important clippings are allowed to remain spread throughout the lawn area, to the extent possible, so that they might aid in building a more productive soil profile and root zone. 2. Mowing other stabilized areas to promote continued growth. Include mowing specification here for other stabilized areas which require maintenance, but not a "groomed" appearance. Also include specifications for mowing areas where it is desirable for woody native volunteer vegetation to become established. This should include attention to mowing stakes or other way of protecting the desired woody natives -from the mowing operation. D. Watering I. Irrigation System Maintenance and Monitoring: If stabilized areas are to be irrigated the design professional should include specifications for the system, its maintenance and its operation in this section. 2. In the absence of an automatic or manual irrigation system, provisions for providing adequate water to stabilized areas should be addressed in this section. 3. (provisions should be made in this section for adjustments to application rates of water during times of regulated droughts and/or periods of excessive rainfall.) E. CONTROL OF INVASIVES: Competition from invasive species can be detrimental to the establishment of the permanent vegetative cover. Left unchecked, these invasives can undermine a revegetation process in a short period of time and eventually lead to unprotected soil and sediment damage. Make site observations monthly to check for the presence of such species and, if found, treat them immediately with the appropriate cultural practices and/or by the use of seasonally -appropriate and site appropriate herbicides. F. Maintenance items including fertilization, mowing, continued soils testing, repair, mulching, matting and soil preparation are to be addressed in the approved construction sequence and on the project bid list. 6.11.22 Rev. 5/08 XIPUea- -V sr..

Accumulated stormwater shall be released if ® found to be uncontaminated by the material stored within the containment area. SECTION B. ANALYTICAL AND QUALITATIVE MONITORING REQUIREMENTS FOR DISCHARGES COMPOSED ENTIRELY OF STORMWATER a Analytical monitoring for stormwater discharges shall be performed for parameters as specified in Tables 1 through 4. All analytical monitoring shall be performed during a representative storm ® event as defined in Part VU. For each parameter, the arithmetic mean of all analytical sampling ® results collected during the term of the permit may be calculated for each individual outfall and compared to the cut-off concentrations listed in Tables 2 and 4. If the arithmetic mean is less ® than the specified cut-off concentration for a given parameter, the facility is not required to continue annual monitoring for that parameter (at that outfall) until the last year of the permit ® unless a significant change in facility operations or configuration occurs. If a cut-off concentration results in discontinued analytical monitoring at an individual discharge outfall, the permittee is required to maintain facility operations that ensure the continuation of stormwater runoff quality. The permittee must perform analytical sampling during the first. and last year of the permit term regardless of cut-off concentration conditions. In situations where stormwater runoff is controlled by some type basin or retention/detention pond, the following provisions are applicable for sample collection for analytical monitoring: • Analytical monitoring for stormwater discharges from a basin or other similar control structures must be performed within the first 30 minutes of discharge. Part III Page 2 of 9 Permit No. NCG020000 2. - Analytical Monitoring for On -site Vehicle Maintenance.
