<br />STORM WATER POLLUTION PREVENTION PLAN BEFORE AND DURING CONSTRUCTION
<br />1. The following storm water pollution prevention measures are shown
<br />on the plans and shall be implemented prior to construction:
<br />* Install silt fence around the perimeter of areas to be graded as
<br />shown on the storm water pollution plan.
<br />* All temporary stockpiles must have silt fence around them to trap
<br />sediment.
<br />" Construct rock construction entrance at field entrance to site.
<br />* Phase grading work to minimize the duration that any disturbed soil
<br />is exposed.
<br />* Seed and mulch must be applied within 72 hours after rough grading is
<br />complete.
<br />* Locate stockpiles a minimum of 50 feet from ponds and site drainage routes.
<br />* Remove any sediment that has been tracked onto public or private streets
<br />within hours.
<br />* Remove any spill of fuel, oil, or other chemical immediately upon detection.
<br />* Store construction materials in an orderly manner.
<br />* Repair silt fences, rock construction entrances, and other erosion and
<br />sediment controls as needed.
<br />2. Storm Water Pollution Prevention After Construction
<br />The contractor shall implement the following storm water pollution prevention
<br />measures after construction:
<br />* All distrubed areas without permanent impermeable surfaces will be
<br />vegetated for final stabilization.
<br />* Silt fence and other erosion and sediment control devices will be removed
<br />after vegetation is establsshed
<br />* Contractor shall maintain a construction activity log with dates of major
<br />grading activities, dates grading stops and spills.
<br />* Keep SWPPP and inspection log accessible on site.
<br />3. Notification
<br />* If the rock construction entrance is filled with sediment the contractor
<br />shall either replace the entrance or add additional rock with 24 hours of
<br />detection or notification
<br />* If sediment from the site is observed on adjacent streets or other properties,
<br />the contractor shall remove the sediment within 24 hours of detection or notification.
<br />* If sediment from the site is observed on adjacent streets or other properties, the
<br />inspector shall identify the source and discharge location of the sediment and instruct
<br />the contractor to implement additional erosion and sediment controls at those
<br />locations to prevent future discharges.
<br />* If building materials, chemicals, or general refuse is being used, stored, disposed
<br />of, or otherwise managed inappropriately, the contractor shall correct such defects
<br />within 24 hours of detection or notification.
<br />If the discharge has occurred on the property, the contractor shall remove the
<br />sediments and debris within 24 hours of notification and correct the source of
<br />such materials as directed by the inspector.

<br />Temporary Erosion Control and Sequencing
<br />1. Install perimeter control fencing per the standard detail plates. No more than
<br />600 linear feet of silt fence should be continuous and collecting at one point.i
<br />tt
<br />Undulate the silt fence or use smles or crescents of silt fence.
<br />2. Install a rock construction entrance per the standard detail plate. Rock pad
<br />exits are needed where the site exits to the private drive. Rock pads should
<br />be 3 inch rock, 6 inches deep, and 75 feet long and span the full width of the
<br />exit. Geotextile fabric should be placed under the rock.
<br />3. Use horizontal slope grading
<br />4. Install erosion control around any temporary dirt stockpile areas.
<br />5. All septic areas to be fenced off for protection. Protection to extend a
<br />minimum of 20' outside of septic areas.
<br />6. The contractor for the project shall inspect all erosion control BMP's after
<br />each rainfall and repair as necessary and remove sediment from silf fences
<br />if it reaches 1/3 capacity.
<br />7. The contractor shall schedule his operations to minimize the amount of
<br />disturbed area at any given time. The contractor shall limit his activities
<br />to the grading limits as shown.
<br />8. Remove all temporary BMP's once the site has reached final stabilization (a
<br />uniform perennial vegetative cover with a density of 70 percent over all pervious
<br />surface areas).
<br />Permanent Erosion Control
<br />1. All exposed soils on she must be stabilized with in 3 days:
<br />a. Stabilization on slopes flatter than 4:1 consists of disc -anchored
<br />mulch and seed; stabilization on slopes flatter than 4:1 and in areas
<br />of concentrated flo=gs consists of erosion blankets and seed.
<br />2. Temporary mulch and seed is needed for exposed areas which sit fallow for
<br />3:1 or steeper in 7 days, 3:1 to 10:1 in 14 days, and flatter than 10:1 in 21
<br />days. Also open stockpiles need to have temporary stabilization if they are to
<br />remain inactive for more than 7 days.
