PART 2 - MATERIALS AND INSTALLATION <br /> 2 . 1 GENERAL <br /> A. Polyacrylamide : As required in Paragraph 1 . 3 . C , place polyacrylamide ( PAM) on bare <br /> ground to reduce the potential for erosion . PAM may also be used in water bodies to <br /> remove turbidity . Use the anionic form of polyacrylamide that does not stick to fish <br /> gills . For PAM information and its proper application , contact Applied Polymer <br /> Systems , Inc. , (678) 494-5998 , www. siltstop . com . <br /> Be Staked Silt Fences : <br /> 1 . General : Use silt fences to control runoff from the construction site where the <br /> soil has been disturbed . <br /> 2 . Installation : Install per the manufacture's recommendations and as specified . <br /> herein . In general , install the silt fence in a manner that allows it to stop the <br /> water long enough for the sediment to settle while the water passes through the <br /> silt fence fabric. All supporting posts shall be on the down-slope side of the <br /> fencing . Place the bottom of the fabric 6-inches minimum , under compacted <br /> soil to prevent the flow of sediment underneath the fence . Place silt fences <br /> away from the toe of slopes . Otherwise , install in accordance with FDOT Index <br /> No . 102 . <br /> 3 . Product : All material shall be new and unused . Use FDOT Types II through IV <br /> silt fences where large sediment loads are anticipated , where slopes are 1 : 2 <br /> (vertical : horizontal) or steeper, or as directed by the ENGINEER ; otherwise use <br /> FDOT Type III silt fence . <br /> (a) For FDOT Type III Silt Fence we ACF Environmental , Catalog No . 360800000, <br /> Florida DOT Silt Fence . U . S . Sieve = 30 , tensile strength = 120 pounds . The <br /> heavy-duty filter fabric shall be pre-attached to 48-inch long stakes on 6-foot <br /> centers . ( 1 -800448-3636) . <br /> (b) For FDOT Type IV Silt Fence , modify the above Catalog No . 360800000 to <br /> comply with FDOT Index No . 102 . <br /> (c) Or equivalent. <br /> C . Turbidily Barriers : <br /> MENNEMENS <br /> 1 . General : Use turbidity barriers to control sediment contamination of <br /> rivers , lakes , ponds , canals , etc . <br /> 2 . Installation : Install per the manufacturer's recommendations and per FDOT <br /> Index No . 103 unless directed otherwise by the ENGINEER . <br /> 3 . Product : All material shall be new and unused . The turbidity barrier shall be a <br /> pervious barrier and the fabric color shall be yellow. <br /> a . Parker Systems , Inc. ( 1 -866-472-7537) , model Type II or Type I <br /> b . Or equivalent . <br /> D . Sedimentation Control From Dewaterinq or Pumping Operations Using Filter Baas : <br /> 1 . Remove silt , sediment, and other particles from dewatering or pumping <br /> applications using a filter bag . The bag shall be manufactured using a <br /> 01025- 8 Technical Specifications <br /> FAIDublic Works\ENGINEERING DIVISION PROJECTS\1102-Old Dixie Hwy Swk 8th St to SR 60=LAPWdmim\bid documentsWaster <br /> Contract Documents\Technical Specifications.doc <br />
