1.6 "POLLUTION" AND CERTAIN UNCONTESTABLE POLLUTION EVENTS DEFINED A. With respect to this Section and as may be further defined in paragraphs 1.6.B, 1.6.C, and 1.6.D, "pollution" is the presence in off-site waters of any substances, contaminants, or manmade or human -induced impairment of off-site waters or alteration of the chemical, physical, biological, or radiological integrity of off-site water in quantities or at levels which are or may be potentially harmful or injurious to human health or welfare, animal or plant life, or property. Pollutants to be removed include but are not limited to, sediment and suspended solids, solid and sanitary wastes, phosphorus, nitrogen, pesticides, oil and grease, concrete truck washout, stucco mixer washout, curb machine washout, washout from other construction equipment, construction chemicals, and construction debris. B. When the Discharge is Directly Into an Existing Water Body An existing water body (including ditches and canals) is defined to be polluted by the CONTRACTOR's operations when at any time, the turbidity of the water immediately downstream of the CONTRACTOR's discharge point(s) is at least 29 nephelometric turbidity units (NTUs) higher than the turbidity of the background water upstream of the discharge point(s). [See Fla. Administrative Code 62- 302.530] Exception: When the discharge is directly into or through an outfall discharging into "Outstanding Florida Waters," designated by Florida Statute 403.061(27), the turbidity of the discharged water cannot exceed the turbidity of the immediate receiving water. The ENGINEER or OWNER shall determine the locations where the turbidity is measured. C. When the Discharge is not Directly Into an Existing Water Body In some instances, dewatering water or stormwater runoff from the construction site or work area may reach a water body indirectly, such as by overland flow. If the discharge water's TSS and turbidity measurements exceed pre -construction background values by 20 percent for TSS and 29 NTUs for turbidity, then the discharge is defined to be polluted. D. When Pollution Always Occurs The discharge from a construction site or work area is defined to be polluted whenever the pH of the discharge is Tess than 6.5 or greater than 8.5, or whenever any of the following is present in the discharge water: (1) Hazardous waste or hazardous materials in any quantity, (2) Any petroleum product or by-product in any quantity, (3) Any chemical in any quantity, or (4) Concentrated pollutants. E. Above paragraphs 1.6.B, 1.6.C, and 1.6.D do not in any way, limit the types of conditions in which pollution may be determined to occur. 1.7 PENALTIES FOR NONCOMPLIANCE WITH THIS SECTION A. In addition to the OWNER's specific remedies, if erosion or pollution is caused by dewatering water or stormwater runoff from the construction site, the OWNER may report the violations to Indian River County Stormwater Enforcement, SJRWMD, Page 1 4 F'\Public Works\ENGINEERING DIVISION PROJECTS\1213B-IRC Shooting Range Skeet & Trap Phase 2\Admin\bid documents\Addendums\Addendum No. 3 Updated Section 104 Technical Specs.doa
