The permittee shall comply with the Erosion and Sediment Control plan approved by the delegated authority having jurisdiction. All details and specifications shown on this sheet may not apply depending on site conditions and the delegated authority having jurisdiction. GROUND STABILIZATION SPECIFICATION Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the techniques in the table below: POLYACRYLAMIDES (PAMS) AND FLOCCULANTS 1.Select flocculants that are appropriate for the soils being exposed during construction, selecting from the NC DWR List of Approved PAMS/Flocculants. 2.Apply flocculants at or before the inlets to Erosion and Sediment Control Measures. 3.Apply flocculants at the concentrations specified in the NC DWR List of Approved PAMS/Flocculants and in accordance with the manufacturer's instructions. 4.Provide ponding area for containment of treated Stormwater before discharging offsite. 5.Store flocculants in leak-proof containers that are kept under storm-resistant cover or surrounded by secondary containment structures. HAZARDOUS AND TOXIC WASTE 1.Create designated hazardous waste collection areas on-site. 2.Place hazardous waste containers under cover or in secondary containment. 3.Do not store hazardous chemicals, drums or bagged materials directly on the ground. EQUIPMENT AND VEHICLE MAINTENANCE 1.Maintain vehicles and equipment to prevent discharge of fluids. 2.Provide drip pans under any stored equipment. 3.Identify leaks and repair as soon as feasible, or remove leaking equipment from the project. 4.Collect all spent fluids, store in separate containers and properly dispose as hazardous waste (recycle when possible). 5.Remove leaking vehicles and construction equipment from service until the problem has been corrected. 6.Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products to a recycling or disposal center that handles these materials. LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE 1.Never bury or burn waste. Place litter and debris in approved waste containers. 2.Provide a sufficient number and size of waste containers (e.g dumpster, trash receptacle) on site to contain construction and domestic wastes. 3.Locate waste containers at least 50 feet away from storm drain inlets and surface waters unless no other alternatives are reasonably available. 4.Locate waste containers on areas that do not receive substantial amounts of runoff from upland areas and does not drain directly to a storm drain, stream or wetland. 5.Cover waste containers at the end of each workday and before storm events or provide secondary containment. Repair or replace damaged waste containers. 6.Anchor all lightweight items in waste containers during times of high winds. 7.Empty waste containers as needed to prevent overflow. Clean up immediately if containers overflow. 8.Dispose waste off-site at an approved disposal facility. 9.On business days, clean up and dispose of waste in designated waste containers. PAINT AND OTHER LIQUID WASTE 1.Do not dump paint and other liquid waste into storm drains, streams or wetlands. 2.Locate paint washouts at least 50 feet away from storm drain inlets and surface waters unless no other alternatives are reasonably available. 3.Contain liquid wastes in a controlled area. 4.Containment must be labeled, sized and placed appropriately for the needs of site. 5.Prevent the discharge of soaps, solvents, detergents and other liquid wastes from construction sites. PORTABLE TOILETS 1.Install portable toilets on level ground, at least 50 feet away from storm drains, streams or wetlands unless there is no alternative reasonably available. If 50 foot offset is not attainable, provide relocation of portable toilet behind silt fence or place on a gravel pad and surround with sand bags. 2.Provide staking or anchoring of portable toilets during periods of high winds or in high foot traffic areas. 3.Monitor portable toilets for leaking and properly dispose of any leaked material. Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replace with properly operating unit. HERBICIDES, PESTICIDES AND RODENTICIDES 1.Store and apply herbicides, pesticides and rodenticides in accordance with label restrictions. 2.Store herbicides, pesticides and rodenticides in their original containers with the label, which lists directions for use, ingredients and first aid steps in case of accidental poisoning. 3.Do not store herbicides, pesticides and rodenticides in areas where flooding is possible or where they may spill or leak into wells, stormwater drains, ground water or surface water. If a spill occurs, clean area immediately. 4.Do not stockpile these materials onsite. CONCRETE WASHOUTS 1.Do not discharge concrete or cement slurry from the site. 2.Dispose of, or recycle settled, hardened concrete residue in accordance with local and state solid waste regulations and at an approved facility. 3.Manage washout from mortar mixers in accordance with the above item and in addition place the mixer and associated materials on impervious barrier and within lot perimeter silt fence. 4.Install temporary concrete washouts per local requirements, where applicable. If an alternate method or product is to be used, contact your approval authority for review and approval. If local standard details are not available, use one of the two types of temporary concrete washouts provided on this detail. 5.Do not use concrete washouts for dewatering or storing defective curb or sidewalk sections. Stormwater accumulated within the washout may not be pumped into or discharged to the storm drain system or receiving surface waters. Liquid waste must be pumped out and removed from project. 6.Locate washouts at least 50 feet from storm drain inlets and surface waters unless it can be shown that no other alternatives are reasonably available. At a minimum, install protection of storm drain inlet(s) closest to the washout which could receive spills or overflow. 7.Locate washouts in an easily accessible area, on level ground and install a stone entrance pad in front of the washout. Additional controls may be required by the approving authority. 8.Install at least one sign directing concrete trucks to the washout within the project limits. Post signage on the washout itself to identify this location. 9.Remove leavings from the washout when at approximately 75% capacity to limit overflow events. Replace the tarp, sand bags or other temporary structural components when no longer functional. When utilizing alternative or proprietary products, follow manufacturer's instructions. 10.At the completion of the concrete work, remove remaining leavings and dispose of in an approved disposal facility. Fill pit, if applicable, and stabilize any disturbance caused by removal of washout. EARTHEN STOCKPILE MANAGEMENT 1.Show stockpile locations on plans. Locate earthen-material stockpile areas at least 50 feet away from storm drain inlets, sediment basins, perimeter sediment controls and surface waters unless it can be shown no other alternatives are reasonably available. 2.Protect stockpile with silt fence installed along toe of slope with a minimum offset of five feet from the toe of stockpile. 3.Provide stable stone access point when feasible. 4.Stabilize stockpile within the timeframes provided on this sheet and in accordance with the approved plan and any additional requirements.

SEED BED PREPARATION: LIMING- Apply lime according to soil test recommendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone at the rate of 1-11 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 10-10-10 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 raking, harrowing, or other suitable methods for fine grading. The finished grade shall be a smooth even soil surface with a loosen uniformly fine texture. All ridges and depressions shall be removed and filled to provide the approved surface drainage. Planting is to be done immediately after finished grades are obtained and seedbed preparation is completed. Refertilize if growth is not fully adequate.

First land-disturbing activity- Stabilize bare areas immediately with gravel and temporary vegetation as construction takes place. SEDIMENT TRAPS AND BARRIERS: Basin traps, sediment fences, and outlet protection. Install principal basins after construction site is accessed. Install additional traps and barriers as needed during grading. RUNOFF CONTROL: Diversions, perimeter dikes, water bars, and outlet protection. Install key practices after principal sediment traps and before land grading. Install additional runoff-control measures during grading. RUNOFF CONVEYANCE SYSTEM: Stabilize streambanks, storm drains, channels, inlet and outlet protection, and slope drains. Where necessary, stabilize streambanks as early as possible. Install principal runoff conveyance system with runoff-control measures. Install remainder of system after grading. LANDING CLEARING AND GRADING: Site preparation- cutting, filling and grading, sediment traps, barriers, diversions, drains, and surface roughening. Begin major clearing and grading AFTER principal sediment and key runoff-control measures are installed. Clear borrow and disposal areas only as needed. Install additional control measures as grading progresses. Mark trees and buffer areas for preservation. SURFACE STABILIZATION: Temporary and permanent seeding, mulching, sodding and riprap. Apply temporary or permanent stabilization measures immediately on all disturbed areas where work is delayed or complete. BUILDING CONSTRUCTION: Buildings, utilities, and paving.Install necessary additional erosion and sedimentation control practices as work takes place. LANDSCAPE AND FINAL STABILIZATION: Topsoiling, trees and shrubs, permanent seeding, mulching, sodding, and riprap. Last construction phase: Stabilize all open areas, including borrow and spoil areas. Remove and stabilize all temporary control areas. NOTE: The above are the main aspects of a typical construction sequence in general terms. A detailed Construction Sequence should be site specific based on your project and site needs. As a minimum, the construction sequence schedule should show the following: ·The erosion and sedimentation control practices to be installed, ·Principal development activities, ·What measures should be in place before other activities are begun, and ·Compatibility with the general construction schedule of the contract. Many timely construction techniques can reduce the erosion potential of a site, such as (1) shaping earthen fills daily to prevent overflows and (2) constructing temporary diversions ahead of anticipated storms. These types of activities cannot be put on the construction sequence schedule, but should be used whenever possible.

Notes: 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. (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 the 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 a minimum 50 pound tensile strength. 5.When a wire mesh support fence is used, space posts a maximum of 8 feet apart. Supports should be driven securely into the ground a minimum of 24 inches. Wire mesh should be a minimum 14-gauge with 6 inch mesh spacing. 6.Extra strength filter fabric with 6 foot post spacing does not require a wire mesh support fence. Securely fasten the filter fabric directly to posts. Wire or plastic zip ties should have a minimum of 50 pound tensile strength. 7.Excavate the trench approximately 4 inches wide and 8 inches deep along the proposed line of the posts and upslope from the barrier. 8.Place 12 inches of 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. 11.Do not place across ditches, streams, or any other areas of concentrated flow. Maintenance: 1.Inspect all measures at least weekly and after each rainfall of 1.0 inch or greater. Make any required repairs immediately. 2.Should the fabric of a sediment fence collapse, tear, decompose, or become ineffective, replace it promptly. 3.Remove sediment deposits as necessary to provide adequate storage volume for the next rain and reduce pressure on the fence. Take care to avoid undermining the fence during cleanouts. 4.Remove all fencing materials and unstable sediment deposits and bring the area to grade and stabilize it after the contributing drainage area has been properly stabilized.

Remove all surface soil containing high amounts of organic matter and stockpile or dispose of it properly. Haul all objectionable material to the designated disposal area. Place temporary sediment control measures below basin as needed. 2.Place the fill in lifts not to exceed 9 inches, and machine compact it. Over fill the embankment 6 inches to allow for settlement. 3.Place the barrel on a firm, smooth foundation of impervious soil. Do not use pervious material such as sand, gravel, or crushed stone as backfill around the pipe. Place the fill around the pipe spillway in 4-inch layers and compact it under and around the pipe to at least the same density as the adjacent embankment. 4.Place a minimum depth of 2 feet compacted backfill over the pipe spillway before crossing with construction equipment. 5.Ensure that the flow length to basin width ratio is at least 2:1 to improve trapping efficiency. Length is measured at the elevation of the principal spillway. 6.Assemble the skimmer following manufacturers instructions or as designed and lay on the bottom of the basin with the flexible joint at the inlet of the barrel pipe. Attach the flexible joint to the barrel pipe and position the skimmer over the excavated pit or support. Be sure to attach a rope and anchor it to the side of the basin.This will be used to pull the skimmer to the side for maintenance. 7.Install the spillway in undisturbed soil to the greatest extent possible. The spillway should be lined with laminated plastic or impermeable geotextile fabric. The fabric must be wide and long enough to cover the bottom and sides and extend onto the top of the dam for anchoring in a trench. The edges may be secured with 8-inch staples or pins. 8.Filter fabric must be long enough to extend down the slope and exit onto stable ground. The width of the fabric must be one piece, not joined or spliced; otherwise water can get under the fabric. 9.The upper section(s) should overlap the lower section(s) so that water cannot flow under the fabric. Secure the upper edge and sides of the fabric in a trench with staples or pins. 10.Discharge water into the basin in a manner to prevent erosion. Use temporary slope drains or diversions with outlet protection to divert sediment-laden water to the upper end of the pool area to improve basin trap efficiency. 11.Stabilize the emergency spillway embankment and all other disturbed areas above the crest of the principal spillway immediately after construction. MAINTENANCE: 1.Inspect all measures at least weekly and after each rainfall of 1.0 inch or greater. Make necessary repairs immediately. 2.Remove sediment and restore the basin to its original dimensions when sediment accumulates to one-half the height of the first baffle. Pull the skimmer to one side so that the sediment underneath can be excavated. Excavate the sediment from the entire basin, not just around the skimmer or within the first cell. 3.Make sure any vegetation growing in the bottom of the basin does not hold down the skimmer. 4.Repair baffles if they are damaged. Re-anchor the baffles if water is flowing underneath or around them. 5.Ensure the skimmer is not clogged with trash or debris. 6.If the skimmer arm or barrel pipe is clogged, remove orifice and clear debris with a plumber’s snake or by flushing with clean water. Be sure to replace the orifice before repositioning the skimmer. 7.Check fabric lined spillway for damage and make any required repairs with fabric that spans the full width of the spillway. Check the embankment, spillways, and outlet for erosion damage, and inspect the embankment for piping and settlement.

If the basin will eventually be converted to a permanent SCM device, the basin must function as a temporary sediment basin and meet the following parameters until completion of the project: ·Maximum Drainage Area: 100 acres ·Minimum Sediment Storage Volume: 1800 cubic feet per acre of disturbed area ·Minimum Surface Area: 435 square feet per cfs of Q10 peak inflow ·Minimum dewatering time: 48 hours 2.Clear, grub, and strip topsoil from areas under the embankment to remove trees, vegetation, roots, and other objectionable material. Delay clearing the pool area until the dam is complete. Stockpile all topsoil or soil containing organic matter for use on the outer shell of the embankment to facilitate vegetative establishment. 3.Place temporary sediment control measures below the basin and stockpile as needed. 4.Excavate a cut-off trench along the center line of the earth fill embankment. Cut trench to stable soil material, but in no case make it less than 2 feet deep with maximum side slopes no steeper than 1:1. Compaction requirements are the same as those for the embankment. 5.Extend the cut-off trench into both abutments to at least the elevation of the riser crest. 6.Keep the trench dry during backfilling and compaction operations. 7.Fill material should be clean mineral soil, free of roots, woody vegetation, rocks, and other objectionable material. Areas of approved fill should be shown on the plans. 8.Scarify areas on which fill is to be placed prior to placing. Ensure that fill material contains sufficient moisture so it can be formed by hand into a ball without crumbling. If water can be squeezed out of the ball, it is too wet for proper compaction. 9.Place fill material in 6 to 8 inch continuous layers over the entire length of fill area and compact. 10.Construct the embankment to an elevation 10% higher than the design height to allow for settling. 11.Securely attach the riser to the barrel or barrel stub to make a watertight structural connection. All connections should be made using approved watertight assemblies. 12.If no riser structure is to be used, couple the skimmer arm directly into the embankment 1 foot from the bottom of the basin. 13.The arm pipe connecting the skimmer to the riser shall have a minimum length of 6 feet. 14.Place barrel and riser on a firm, smooth foundation of impervious soil. 15.Do not use pervious material such as sand, gravel, or crushed stone as backfill around the pipe or anti-seep collars. 16.Place fill material around the pipe spillway in 4-inch layers, and compact it under and around the pipe to at least the same density as the adjacent embankment. 17.Place a minimum depth of 2 feet of compacted backfill over the pipe spillway before crossing it with any construction equipment. 18.Anchor riser in place by concrete or other satisfactory means to prevent floatation. 19.In no case should the pipe conduit be installed by cutting a trench through the dam after the embankment is complete. 20.Install the emergency spillway in undisturbed soil. 21.Discharge water into the basin in a manner to prevent erosion. 22.Construct basin so that the disturbed area is minimized, divert surface water from bare areas and complete the embankment before the area is cleared. 23.Stabilize the emergency spillway embankment and all other disturbed area above the crest of the principal spillway immediately after construction. 24.Seed and place matting for erosion control on interior and exterior side slopes. 25.Install Porous Baffles as specified on following sheets. MAINTENANCE: 1.Inspect all measures at least weekly and after each rainfall of 1.0 inch or greater. Make any repairs immediately. 2.Remove sediment and restore basin to its original dimensions when it accumulates to one-half the design depth. 3.Place removed sediment in an area with sediment control measures to ensure no loss of sediment off-site. 4.Check the embankment, spillways, and outlet for erosion damage, and inspect the embankment for piping and settlement. 5.Remove all trash and other debris form the riser and pool area.
