and 1.6.D, "pollution" is the presence in off-site waters of any substances, <br /> contaminants, or manmade or human-induced impairment of off-site waters or <br /> alteration of the chemical, physical, biological, or radiological integrity of off-site water <br /> in quantities or at levels which are or may be potentially harmful or injurious to human <br /> health or welfare, animal or plant life, or property. Pollutants to be removed include but <br /> are not limited to, sediment and suspended solids, solid and sanitary wastes, <br /> phosphorus, nitrogen, pesticides, oil and grease, concrete truck washout, stucco mixer <br /> 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, Pollution Occurs When . . <br /> An existing water body (including ditches and canals) is defined to be polluted by the <br /> CONTRACTOR's operations when at any time, the turbidity of the water immediately <br /> downstream of the CONTRACTOR's discharge point(s) is at least 29 nephelometric <br /> turbidity units (NTUs) higher than the turbidity of the background water upstream of the <br /> discharge point(s). [See Fla. Administrative Code 62-302.530] Exception: When the <br /> discharge is directly into or through an outfall discharging into "Outstanding Florida <br /> Waters," designated by Florida Statute 403.061(27), the turbidity of the discharged <br /> water cannot exceed the turbidity of the immediate receiving water. The ENGINEER <br /> or OWNER shall determine the locations where the turbidity is measured. <br /> C. When the Discharge is not Directly Into an Existing Water Body, Pollution 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 1.6.13, 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.
