anionic form of polyacrylamide that does not stick to fish gills. For PAM information <br />and its proper application, a contact is Applied Polymer Systems, Inc., (678) 494- <br />5998, www.siltstop.com. <br />B. Staked Silt Fences: <br />1. General: Use silt fences to control runoff from the construction site where <br />the soil has been disturbed. <br />2. Installation: Install per the manufacture's recommendations and as <br />specified herein. In general, install the silt fence in a manner that allows it <br />to stop the water long enough for the sediment to settle while the water <br />passes through the silt fence fabric. All supporting posts shall be on the <br />down-slope side of the fencing. Place the bottom of the fabric 6 -inches <br />minimum, under compacted soil to prevent the flow of sediment underneath <br />the fence. Place silt fences away from the toe of slopes. <br />3. Product: All material shall be new and unused. Use FDOT Types III through <br />IV silt fences where large sediment loads are anticipated, where slopes are <br />1:2 (vertical: horizontal) or steeper, or as directed by the ENGINEER; <br />otherwise use FDOT Type II silt fence. <br />C. Turbidity Barriers: <br />1. General: Use turbidity barriers to control sediment contamination of rivers, <br />lakes, ponds, canals, etc. <br />2. Installation: Install per the manufacturer's recommendations unless directed <br />otherwise by the ENGINEER. <br />3. Product: All material shall be new and unused. The turbidity barrier shall <br />be a pervious barrier and the fabric. color shall be yellow. Use staked <br />turbidity barriers in water less than one -foot deep. Use floating turbidity <br />barriers in water one -foot or deeper. <br />D. Sedimentation Control From Dewaterinq or Pumpinq Operations Usina Filter Baas: <br />1. Filter bags shall be manufactured using a polypropylene non -woven <br />geotextile and sewn by a double -needle machine, using a high strength <br />nylon thread. The bag shall have a fill spout large enough to accommodate <br />a 4 -inch pump discharge hose. Straps shall be attached to the bag to <br />secure the hose and prevent pumped water from escaping without being <br />filtered. <br />2. Installation: Install in accordance with the manufacturer's specifications. <br />Use as many filter bags as required, at no additional cost to the OWNER. <br />Legally dispose of the bags offsite, at no cost to the OWNER. If the bags <br />are placed on aggregate to facilitate filtration efficiency, do not use limerock <br />aggregate — use non -calcareous rock. <br />3. Product: The filter bag shall be supplied with lifting straps. <br />a. "DIRTBAG 53 or 55 as applicable," supplied by ACF <br />Environmental, Inc. (1-800-448-3636). <br />b. "DANDY DEWATERING BAG" supplied by Dandy Products, Inc. <br />(1-800-591-2284). <br />C.
