I <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 truckwashout, stucco mixer , <br /> washout, curb machine washout, washout from other construction equipment, <br /> construction chemicals, and construction debris. j. <br /> d <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(NTUs) <br /> higher than the turbidity of the background water upstream of the discharge point(s). !i <br /> [See Fla.Administrative Code 62-302.5301 Exception:When the discharge is directly <br /> into or through an outfall discharging into"Outstanding Florida Waters,"designated by <br /> Florida Statute 403.061(27), the turbidity of the discharged water cannot exceed the i <br /> turbidity of the immediate receiving water. The ENGINEER or OWNER shall <br /> 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 percent j <br /> for TSS and 29 NTUs for turbidity, then the discharge is defined to be 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 less 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 1.6.13, 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 PENALTIE$_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 <br /> Drainage District, as appropriate), and other pertinent regulatory or enforcement <br /> agencies. i <br /> i <br /> PART 2 - MATERIALS AND INSTALLATION <br /> I <br /> 01025-15 Technical Specifications <br /> I <br /> FAPublic WorksIENGINEERING DIVISION PROJECTS\1123 43rd Ave Sidewalk Improvements 26th St.to Airport Dr West\Admim\bid <br /> documents\Master Contract Documents\Technical Specifications.doc i <br />
