Addendum #1 <br />but are not limited to, sediment and suspended solids, solid and sanitary wastes, <br />phosphorus, nitrogen, pesticides, oil and grease, concrete truck washout, stucco <br />mixer washout, curb machine washout, washout from other construction equipment, <br />construction chemicals, and construction debris. <br />B. When the Discharge is Directly Into an Existing Water Body An existing water body <br />(including ditches and canals) is defined to be polluted by the CONTRACTOR's <br />operations when at any time, the turbidity of the water immediately downstream of the <br />CONTRACTOR's discharge point(s) is at least 29 nephelometric turbidity units <br />(NTUs) higher than the turbidity of the background water upstream of the discharge <br />point(s). [See Fla. Administrative Code 62-302.530] Exception: When the discharge <br />is directly into or through an outfall discharging into "Outstanding Florida Waters," <br />designated by Florida Statute 403.061(27), the turbidity of the discharged water <br />cannot exceed the turbidity of the immediate receiving water. The ENGINEER or <br />OWNER shall determine the locations where the turbidity is measured. <br />C. When the Discharge is not Directly Into an Existing Water Body In some instances, <br />dewatering water or stormwater runoff from the construction site or work area may <br />reach a water body indirectly, such as by overland flow. If the discharge water's TSS <br />and turbidity measurements exceed pre -construction background values by 20 <br />percent for TSS and 29 NTUs for turbidity, then the discharge is defined to be <br />polluted. <br />D. When Pollution Always Occurs The discharge from a construction site or work area is <br />defined to be polluted whenever the pH of the discharge is Tess than 6.5 or greater <br />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 may <br />report the violations to Indian River County Stormwater Enforcement, SJRWMD, <br />FDEP, Indian River Farms Water Control District (or other F. S. Chapter 298 Drainage <br />District, as appropriate), and other pertinent regulatory or enforcement 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 and cover it with hay, jute, or mulch.
