'�"i .4'l� Site #15 B Job • Sediment released into wetlands beyond permitted impact area. • Fill slope located near the 1St equalizer pipe west side of the bridge not properly stabilized and has potential to erode into the wetland and open water at the pipe. • Turbid water located at inlet of equalizer pipe. • Action Items: o Using rakes, shovels and buckets remove as much of the sediment that was released into the wetlands. Only get the areas where the sediment is thicker and removal will not cause a greater impact to the area o Re-assess the drainage area that feeds this location as it appears there may be sediment coming down the slope across the side road and adding to the load. Would suggest a rock check dam or wattles. o Install rip-rap and fabric around the basin. o Using what organic soils are on-site back fill over excavated area around the equalizer pipe to restore grade and provide additional erosion control measures to prevent turbid water from entering the equalizer pipe. o In the areas where the slopes and not stabilized beyond the silt fence, please finish out the fill slope using dirt, fabric, and stone to stabilize the area.
