NTS NTS GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCE WITH THE NCGO1 CONSTRUCTION GENERAL PERMIT Implementing the details and specifications on this plan sheet will result in the construction activity being considered compliant with the Ground Stabilization and Materials Handling sections of the NCGO1 Construction General Permit (Sections E and F, respectively). 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: After the 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 Permanent Stabilization • Temporary grass seed covered with straw or • Permanent grass seed covered with straw or other mulches and tackifiers other mulches and tackifiers • Hydroseeding • Geotextile fabrics such as permanent soil • Rolled erosion control products with or reinforcement matting without temporary grass seed • Hydroseeding • Appropriately applied straw or other mulch • Shrubs or other 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 grass seed 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 I 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. 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.
