human health or welfare , animal or plant life , or property . Pollutants to be removed <br /> include but are not limited to , sediment and suspended solids , solid and sanitary <br /> wastes , phosphorus , nitrogen , pesticides , oil and grease , concrete truck washout , <br /> stucco mixer washout , curb machine washout , washout from other construction <br /> equipment , construction chemicals , and construction debris . <br /> B . When the Discharge is Directly Into an Existinq Water Body Pollution Occurs When <br /> An existing water body ( including ditches and canals) is defined to be polluted <br /> by the CONTRACTOR ' s operations when at any time , the turbidity of the water <br /> immediately downstream of the CONTRACTOR ' s discharge point(s) is at least 29 <br /> nephelometric turbidity units ( NTUs) higher than the turbidity of the background <br /> water upstream of the discharge point(s) . [See Fla . Administrative Code 62 . <br /> 302 . 530 ] Exception : When the discharge is directly into or through an outfall <br /> discharging into " Outstanding Florida Waters , " designated by Florida Statute <br /> 403 . 061 (27 ) , the turbidity of the discharged water cannot exceed the turbidity of the <br /> immediate receiving water. The ENGINEER or OWNER shall determine the <br /> locations where the turbidity is measured . <br /> C . When the Discharae is not Directly Into an Existinq 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 <br /> traveling through pipes or by overland flow . Before construction commences , the <br /> Contractor will measure background levels of total suspended solids (TSS ) and <br /> turbidity , in the immediate vicinity of the discharge water' s ultimate discharge point <br /> into the receiving water body . If the discharge water' s TSS and turbidity <br /> measurements exceed these pre-construction background values by 20 percent for <br /> TSS and 29 NTUs for turbidity , then the discharge from the CONTRACTOR ' s <br /> 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 <br /> 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 <br /> Board , SJRWMD , FDEP , Indian River Farms Water Control District ( or other F . S . <br /> Chapter 298 Drainage District , as appropriate ) , and other pertinent regulatory or <br /> enforcement agencies . <br /> 01025-7 Technical Specifications <br /> FAPublic Works\ENGINEERING DIVISION PROJECTS\1142- Misc Culvert ReplacementsWdmim\bid documents\Technical <br /> Specification s .doc <br />
