Thepermittee shall comply with the Erosion and Sediment Control plan approved by thedelegated authority having jurisdiction. All details and specifications shown on this sheetmay not apply depending on site conditions and the delegated authority having jurisdiction.GROUND STABILIZATION SPECIFICATIONStabilize the ground sufficiently so that rain will not dislodge the soil. Use one of thetechniques in the table below:POLYACRYLAMIDES (PAMS) AND FLOCCULANTS1.Select flocculants that are appropriate for the soils being exposed duringconstruction, 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 ApprovedPAMS/Flocculants and in accordance with the manufacturer's instructions.4.Provide ponding area for containment of treated Stormwater before dischargingoffsite.5.Store flocculants in leak-proof containers that are kept under storm-resistant coveror surrounded by secondary containment structures.HAZARDOUS AND TOXIC WASTE1.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 MAINTENANCE1.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 theproject.4.Collect all spent fluids, store in separate containers and properly dispose ashazardous waste (recycle when possible).5.Remove leaking vehicles and construction equipment from service until the problemhas been corrected.6.Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum productsto a recycling or disposal center that handles these materials.LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE1.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, trashreceptacle) on site to contain construction and domestic wastes.3.Locate waste containers at least 50 feet away from storm drain inlets and surfacewaters unless no other alternatives are reasonably available.4.Locate waste containers on areas that do not receive substantial amounts of runofffrom 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 orprovide 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 ifcontainers 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 WASTE1.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 surfacewaters 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 fromconstruction sites.PORTABLE TOILETS1.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 footoffset is not attainable, provide relocation of portable toilet behind silt fence or placeon a gravel pad and surround with sand bags.2.Provide staking or anchoring of portable toilets during periods of high winds or in highfoot 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 replacewith properly operating unit.HERBICIDES, PESTICIDES AND RODENTICIDES1.Store and apply herbicides, pesticides and rodenticides in accordance with labelrestrictions.2.Store herbicides, pesticides and rodenticides in their original containers with thelabel, which lists directions for use, ingredients and first aid steps in case ofaccidental poisoning.3.Do not store herbicides, pesticides and rodenticides in areas where flooding ispossible or where they may spill or leak into wells, stormwater drains, ground wateror surface water. If a spill occurs, clean area immediately.4.Do not stockpile these materials onsite.CONCRETE WASHOUTS1.Do not discharge concrete or cement slurry from the site.2.Dispose of, or recycle settled, hardened concrete residue in accordance with localand state solid waste regulations and at an approved facility.3.Manage washout from mortar mixers in accordance with the above item and inaddition place the mixer and associated materials on impervious barrier and withinlot perimeter silt fence.4.Install temporary concrete washouts per local requirements, where applicable. If analternate method or product is to be used, contact your approval authority forreview and approval. If local standard details are not available, use one of the twotypes of temporary concrete washouts provided on this detail.5.Do not use concrete washouts for dewatering or storing defective curb or sidewalksections. Stormwater accumulated within the washout may not be pumped into ordischarged to the storm drain system or receiving surface waters. Liquid waste mustbe pumped out and removed from project.6.Locate washouts at least 50 feet from storm drain inlets and surface waters unless itcan 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 receivespills or overflow.7.Locate washouts in an easily accessible area, on level ground and install a stoneentrance pad in front of the washout. Additional controls may be required by theapproving authority.8.Install at least one sign directing concrete trucks to the washout within the projectlimits. Post signage on the washout itself to identify this location.9.Remove leavings from the washout when at approximately 75% capacity to limitoverflow events. Replace the tarp, sand bags or other temporary structuralcomponents when no longer functional. When utilizing alternative or proprietaryproducts, follow manufacturer's instructions.10.At the completion of the concrete work, remove remaining leavings and dispose ofin an approved disposal facility. Fill pit, if applicable, and stabilize any disturbancecaused by removal of washout.EARTHEN STOCKPILE MANAGEMENT1.Show stockpile locations on plans. Locate earthen-material stockpile areas at least50 feet away from storm drain inlets, sediment basins, perimeter sediment controlsand surface waters unless it can be shown no other alternatives are reasonablyavailable.2.Protect stockpile with silt fence installed along toe of slope with a minimum offset offive 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 accordancewith the approved plan and any additional requirements. Soil stabilization is definedas vegetative, physical or chemical coverage techniques that will restrain acceleratederosion on disturbed soils for temporary or permanent control needs.SECTION E: GROUND STABILIZATIONRequired Ground Stabilization TimeframesNote: After the permanent cessation of construction activities, any areas with temporaryground stabilization shall be converted to permanent ground stabilization as soon aspracticable but in no case longer than 90 calendar days after the last land disturbingactivity. Temporary ground stabilization shall be maintained in a manner to render thesurface stable against accelerated erosion until permanent ground stabilization is achieved.Site Area DescriptionTimeframe variations-7 days for perimeter dikes, swales,ditches, perimeter slopes and HQW Zones-10 days for Falls Lake Watershed unlessthere is zero slopeStabilize within thismany calendardays after ceasingland disturbance77714NoneNone(a)Perimeter dikes,swales, ditches, andperimeter slopes(b)High Quality Water(HQW) Zones(c)Slopes steeper than3:1If slopes are 10' or less in length and arenot steeper than 2:1, 14 days areallowed(d)Slopes 3:1 to 4:1(e)Areas with slopesflatter than 4:114-7 days for slopes greater than 50' inlength and with slopes steeper than 4:1-7 days for perimeter dikes, swales,ditches, perimeter slopes and HQWZones-10 days for Falls Lake Watershed
