1.6 "POLLUTION" AND CERTAIN UNCONTESTABLE POLLUTION EVENTS <br />DEFINED <br />A. Except as may be defined otherwise in paragraphs 1.6.B, 1.6.C, and 1.6.D, <br />"pollution" is the presence in off-site waters of any substances, contaminants, <br />or manmade or human -induced impairment of waters or alteration of the <br />chemical, physical, biological, or radiological integrity of water in quantities or <br />at levels which are or may be potentially harmful or injurious to human health <br />or welfare, animal or plant life, or property. Pollutants to be removed include <br />but are not limited to, sediment and suspended solids, solid and sanitary <br />wastes, phosphorus, nitrogen, pesticides, oil and grease, concrete truck <br />washout, construction chemicals, and construction debris. <br />B. When the Discharge is Directly Into an Existing Water Body, Pollution Occurs <br />When ... An existing water body (including ditches and canals) is defined to <br />be polluted by the CONTRACTOR's operations when at any time, the <br />turbidity of the water immediately downstream of the CONTRACTOR's <br />discharge point(s) is 29 nephelometric turbidity units (NTUs) higher than the <br />turbidity of the background water upstream of the discharge point(s). [See <br />Fla. Administrative Code 62-302.530] 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, Pollution <br />Occurs When ... In some instances, dewatering water or stormwater runoff <br />from the construction site or work area may reach a water body indirectly, <br />such as after traveling through pipes or by overland flow. Before <br />construction commences, the OWNER or ENGINEER will measure <br />background levels of total suspended solids (TSS) and turbidity, in the <br />immediate vicinity of the discharge water's ultimate discharge point into the <br />receiving water body. If the discharge water's TSS and turbidity <br />measurements exceed these pre -construction background values by 29 <br />NTUs for turbidity, then the discharge from the CONTRACTOR's operations <br />is defined to be polluted. <br />D. Pollution Always Occurs When ... The discharge is defined to be polluted <br />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.B, 1.6.C, and 1.6.D do not in any way, limit the types <br />of conditions in which pollution may be determined to occur. <br />F:\Engineering\Capital Projects10381 Oslo Road Boat Ramp\0381 Contract Documents and Specifications\Technical Specifications - <br />Revised 10-02-08.doc <br />
