Addendum #1 11 -06-2013 Be When the Discharge is Directly Into an Existing Water Body, Pollution Occurs When 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, Pollution Occurs When . . . In some instances , dewatering water or stormwater runoff from the construction site or work area may reach a water body indirectly , such as after traveling through pipes or by overland flow . Before construction commences , the Contractor will measure background levels of total suspended solids (TSS ) and turbidity, in the immediate vicinity of the discharge water' s ultimate discharge point into the receiving water body . If the discharge water' s TSS and turbidity measurements exceed these pre-construction background values by 20 percent for TSS and 29 NTUs for turbidity , then the discharge from the CONTRACTOR' s operations is defined to be polluted . D . Pollution Always Occurs When . . . The discharge from a construction site or work area is defined to be polluted whenever the pH of the discharge is less 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 . 13 , 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 will immediately report the violations to the Indian River County Code Enforcement Board , SJRWMD , FDEP , Indian River Farms Water Control District (or other F . S . Chapter 298 Drainage District , as appropriate ) , and other pertinent regulatory or enforcement agencies . PART 2 - MATERIALS AND INSTALLATION 2 . 1 GENERAL A . Polvacrylamide : As required in Paragraph 1 . 3 . C , place polyacrylamide ( PAM ) on MENNEN bare ground to reduce the potential for erosion . PAM may also be used in water bodies to remove turbidity. Use the anionic form of polyacrylamide that does not stick to fish gills .
