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. SECTION E: GROUND STABILIZATION Required Ground Stabilization Timeframes Stabilize within this Site Area Description many calendar Timeframe variations days after ceasing land disturbance (a) Perimeter dikes, swales, ditches, and 7 None perimeter slopes (b) High Quality Water 7 None (HQW) Zones (c) Slopes steeper than If slopes are 10' or less in length and are 3:1 7 not steeper than 2:1, 14 days are allowed -7 days for slopes greater than 50' in length and with slopes steeper than 4:1 -7 days for perimeter dikes, swales, (d) Slopes 3:1 to 4:1 14 ditches, perimeter slopes and HQW Zones -10 days for Falls Lake Watershed -7 days for perimeter dikes, swales, (e) Areas with slopes ditches, perimeter slopes and HQW Zones flatter than 4:1 14 -10 days for Falls Lake Watershed unless there is zero slope Note: Afterthe permanent cessation of construction activities, any areas with temporary ground stabilization shall be converted to permanent ground stabilization as soon as practicable but in no case longer than 90 calendar days after the last land disturbing activity. Temporary ground stabilization shall be maintained in a manner to render the surface stable against accelerated erosion until permanent ground stabilization is achieved. GROUND STABILIZATION SPECIFICATION Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the techniques in the table below: Temporary Stabilization i Permanent Stabilization • Temporary grass seed covered with straw or I • Permanent grass seed covered with straw or other mulches and tackifiers other mulches and tackifiers • Hydroseeding • G eotextile fabrics such as permanent soil • Rolled erosion control products with or i reinforcement matting without temporary grass seed • Hydroseeding • Appropriately applied straw or other mulch • Shrubs orother permanent plantings covered • Plastic sheeting with mulch • Uniform and evenly distributed ground cover sufficient to restrain erosion • Structural methods such as concrete, asphalt or retaining walls • Rolled erosion control products with zrass seed POLYACRYLAMIDES (PAMS) AND FLOCCULANTS I. 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 offs ite. 5. Store flocculants in leak -proof containers that are kept under storm -resistant cover or surrounded by secondary containment structures. 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. S. 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. Preventthe discharge of soaps, solvents, detergents and other liquid wastes from construction sites. PORTABLE TOILETS 1. Install portable toilets an 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. 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. Soil stabilization is defined as vegetative, physical or chemical coverage techniques that will restrain accelerated erosion on disturbed soils for temporary or permanent control needs. .4 NORTH CAROLINA f, Environmental Quality ONSITE CONCRETE WASHOUT STRUCTURE WITH LINER �a . r>tna a f t I��I �oma�� ails rrr 3023Klc11L . awaa ml avre r �' I � tea. � i�a wane iacwo a Hsu :�s�.�ira a aa.wssa v I 1swr�'fiaomm`r��'w` •raw spy &#§Mp smEruRr AWVK CiR%HRWff STRIMME CONCRETE WASHOUTS 1.

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. S. 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. HERBICIDE5, PESTICIDES AND RODENTICIDES 1. Store and apply herbicides, pesticides and rodenticides in accordance with label restrictions. 2.
