P <br /> 6. MONITORING AND SAMPLING <br /> The ultimate receiving water for the pit dewatering activities is the St, Charles River. Storm water will be <br /> pumped from the quarry sedimentation pond to an unnamed arroyo. <br /> Storm water discharges will be monitored and sampled by the SWMP Administrator or personnel qualified <br /> to determine the quality of such discharge. As required by the Part I.B.1.b. of the Permit samples will be <br /> obtained two days per month when a discharge occurs. Samples will be taken at the outlet of the <br /> pump/hose used to remove water retained in the sedimentation pond. Storm water samples will be tested <br /> for pH, total suspended solids(TSS) oil and grease Estimated storm water flow rate will be determined <br /> and recorded on the sampling record. <br /> Any source of pollutants contaminating storm water runoff from the quarry will be identified and steps <br /> taken to reduce to acceptable levels, or eliminate the contaminant from entering the runoff flow. The <br /> actions taken to identify pollution sources will be identified and described in an inspection report. <br /> 15 <br />
