Permittee : Indian River County Beach Restoration Permit No : 01669294014C Page 13 of 17 is responsibility to ensure that evidence intrinsic to the specimen is not unnecessarily disturbed. MONITORING REQUIRED : 14 . Water Quality Monitoring (Turbidity ) A . Borrow Site : Frequency: Every six hours during dredging. Location: Background: Mid-depth, at least 300 meters upcurrent from the dredge site, clearly outside of any turbidity generated by the project. Compliance : Mid-depth, no more than 150 meters downcurrent from the dredge site, within the densest portion of any visible turbidity plume. B . Beach Disposal Area: Frequency: Every six hours during pumping operations . Location: Background: Mid-depth, at a point approximately 150 meters offshore and 1 ,000 meters upcurrent from the discharge point, clearly outside of any turbidity generated by the project. Compliance : Mid-depth, at a point approximately 150 meters offshore and no more than 1000 meters downcurrent from the discharge point, within the densest portion of any visible turbidity plume. Weekly summaries of all monitoring data shall be submitted to the Bureau of Beaches and Wetland Resources and to the Central District Office within one week of collection with documents containing the following information: ( 1 ) permit number; (2) dates and times of sampling and analysis ; (3 ) a statement describing the methods used in collection, handling, storage and analysis of the samples ; (4) a map indicating the sampling locations, current direction, plume configuration and the location of the dredge and discharge point(s) ; and (5) a statement by the individual responsible for implementation of the sampling program concerning the authenticity, precision, limits of detection and accuracy of the data. Monitoring reports shall also include the following information for each sample that is taken : a) time of day samples taken; b) depth of water body; c) depth of sample ; d) antecedent weather conditions ; e) tidal stage and direction of flow; f) wind direction and velocity; and g) DGPS position. The compliance locations given above shall be considered the limits of the temporary mixing zone for turbidity allowed during construction. If monitoring reveals turbidity levels at the compliance sites are greater than 29 NTUs above the associated background turbidity levels, construction activities shall cease immediatelv and not resume until corrective measures have been taken and turbidity has returned to acceptable levels .
