or OWNER shall determine the locations where the turbidity is measured. <br />C. When the Discharge is not Directly Into an Existing Water Body, Pollutjon Occurs <br />When . . . In some instances, dewatering water or stormwater runoff from the <br />construction site or work area may reach a water body indirectly, such as after traveling <br />through pipes or by overland flow. Before construction commences, the Contractor will <br />measure background levels of total suspended solids (TSS) and turbidity, in the <br />immediate vicinity of the discharge water's ultimate discharge point into the receiving <br />water body. If the discharge water's TSS and turbidity measurements exceed these <br />pre -construction background values by 20 percent for TSS and 29 NTUs for turbidity, <br />then the discharge from the CONTRACTOR's operations is defined to be polluted. <br />D. Pollution Always Occurs When ... The discharge from a construction site or work <br />area is defined to be polluted whenever the pH of the discharge is less than 6.5 or <br />greater than 8.5, or whenever any of the following is present in the discharge water: <br />(1) Hazardous waste or hazardous materials in any quantity, <br />(2) Any petroleum product or by-product in any quantity, <br />(3) Any chemical in any quantity, or <br />(4) Concentrated pollutants. <br />E. Above paragraphs 1.6.B, 1.6.C, and 1.6.D do not in any way, limit the types of <br />conditions in which pollution may be determined to occur. <br />1.7 PENALTIES FOR NONCOMPLIANCE WITH THIS SECTION <br />A. In addition to the OWNER's specific remedies, if erosion or pollution is caused by <br />dewatering water or stormwater runoff from the construction site, the OWNER will <br />immediately report the violations to the Indian River County Code Enforcement Board, <br />SJRWMD, FDEP, Indian River Farms Water Control District (or other F. S. Chapter <br />298 Drainage District, as appropriate), and other pertinent regulatory or enforcement <br />agencies. <br />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 />B. 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 tl rough 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 />01025-7 Technical Specifications <br />F:\Public Works\ENGINEERING DIVISION PROJECTS\1314-107th Ave Millina 90th St to 94th St\Admin\bid documents\Master Contract <br />
