The following storm water pollution prevention measures are shown on the plans and shall be implemented prior to construction: * Install silt fence around the perimeter of areas to be graded as shown on the storm water pollution plan. * All temporary stockpiles must have silt fence around them to trap sediment. * Construct rock construction entrance at field entrance to site. * Phase grading work to minimize the duration that any disturbed soil is exposed. * Seed and mulch must be applied within 72 hours after rough grading is complete. * Locate stockpiles a minimum of 50 feet from ponds and site drainage routes. * Remove any sediment that has been tracked onto public or private streets within hours. * Remove any spill of fuel, oil, or other chemical immediately upon detection. * Store construction materials in an orderly manner. * Repair silt fences, rock construction entrances, and other erosion and sediment controls as needed. 2. Storm Water Pollution Prevention After Construction The contractor shall implement the following storm water pollution prevention measures after construction: * All distrubed areas without permanent impermeable surfaces will be vegetated for final stabilization. * Silt fence and other erosion and sediment control devices will be removed after vegetation is established * Contractor shall maintain a construction activity log with dates of major grading activities, dates grading stops and spills.Temporary Erosion Control and Sequencing 1. Install perimeter control fencing per the standard detail plates. No more than 600 linear feet of silt fence should be continuous and collecting at one point. Undulate the silt fence or use "simles" or crescents of silt fence.2. Install a rock construction entrance per the standard detail plate. Rock pad exits are needed where the site exits to the private drive. Rock pads should be 3 inch rock, 6 inches deep, and 75 feet long and span the full width of the exit. Geotextile fabric should be placed under the rock.3. Use horizontal slope grading4. Install erosion control around any temporary dirt stockpile areas. 5. All septic areas to be fenced off for protection. Protection to extend a minimum of 20' outside of septic areas.6. The contractor for the project shall inspect all erosion control BMP's after each rainfall and repair as necessary and remove sediment from silf fences if it reaches 1/3 capacity. 7. The contractor shall schedule his operations to minimize the amount of disturbed area at any given time. The contractor shall limit his activities to the grading limits as shown. 8. Remove all temporary BMP's once the site has reached final stabilization (a uniform perennial vegetative cover with a density of 70 percent over all pervious surface areas). Permanent Erosion Control 1. All exposed soils on site must be stabilized with in 3 days: a. Stabilization on slopes flatter than 4:1 consists of disc-anchored mulch and seed; stabilization on slopes flatter than 4:1 and in areas of concentrated flows consists of erosion blankets and seed. 2. Temporary mulch and seed is needed for exposed areas which sit fallow for 3:1 or steeper in 7 days, 3:1 to 10:1 in 14 days, and flatter than 10:1 in 21 days. Also open stockpiles need to have temporary stabilization if they are to remain inactive for more than 7 days. 3. Notification * If the rock construction entrance is filled with sediment the contractor shall either replace the entrance or add additional rock with 24 hours of detection or notification * If sediment from the site is observed on adjacent streets or other properties, the contractor shall remove the sediment within 24 hours of detection or notification. * If sediment from the site is observed on adjacent streets or other properties, the inspector shall identify the source and discharge location of the sediment and instruct the contractor to implement additional erosion and sediment controls at those locations to prevent future discharges. * If building materials, chemicals, or general refuse is being used, stored, disposed of, or otherwise managed inappropriately, the contractor shall correct such defects within 24 hours of detection or notification. * If excessive sediments or debris are observed at the flared end section outfalls, the inspector shall determine the source and discharge locations of such materials. If the discharge has occurred on the property, the contractor shall remove the sediments and debris within 24 hours of notification and correct the source of such materials as directed by the inspector.
