KLE/NFELOER <br /> eynrr.oeie.x;emsoronon,. <br /> • 5.2 SURFACE WATER MONITORING <br /> The RWQCB's Monitoring and Reporting Program (MRP) No. 97-811 requires that <br /> "Visual inspections shall be made daily at all points at which surface runoff may leave <br /> the nursery and enter Potter Creek. These discharge points include, but are not limited <br /> to, the pipes from the tailwater holding pond (Basin A and B) and the roadside drainage <br /> ditch along Escalon Bellota Road." The MRP required sampling of 3 locations in <br /> addition to all discharge locations. Included in the surface water discussion is the <br /> dewatering discharge. While it is technically groundwater, it is discharged to a basin on <br /> site. Norman's Nursery has consistently exceeded the number of monitoring locations <br /> required. <br /> Surface water monitoring and visual inspections were conducted by Norman's Nursery <br /> personnel. A discussion of the flows, observations and chemical results are detailed in <br /> the following sections of this report. For a summary of the flows and chemical results, <br /> please refer to Tables 4 and 5 beneath the "Tables" tab of this report. <br /> • 5.2.1 Surface Water Flow <br /> Surface water was observed by Norman's Nursery staff at specified locations from <br /> January 1 through June 30, 2012. Flow rates were monitored for a total of 91 days <br /> during the first quarter and 91 days during the second quarter. Surface water flow data <br /> is shown in Table 4 in the Appendix. <br /> The following table describes the surface water monitoring locations. <br /> Sample <br /> Location Sample Location <br /> No. <br /> S-1A Farthest upstream sample location on Potter Creek (approx. 200 feet <br /> u stream of S1 <br /> Discharge of the drainage that cuts across Norman's Nursery property <br /> S-1 from the south to the north and enters Potter Creek after the new Basin A <br /> near the northeastern portion of the nursery property <br /> D-2 Discharge from Basin A <br /> S-2 Potter Creek monitoring location approximately 750 feet upstream of the <br /> discharge from Basin B <br /> S-3 Basin B <br /> • D-1 Discharge from Basin B (S-3) <br /> 117226.E02/ST012R0696 Page 26 of 43 September 14, 2012 <br /> Copyright 2012 Kleinfelder <br />
