r • <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> MONITORING AND REPORTING PROGRAM NO. 90-095 <br /> FOR <br /> SIMPSON INVESTMENT COMPANY <br /> AND <br /> SIMPSON PAPER COMPANY <br /> RIPON MILL <br /> SAN JOAQUIN COUNTY <br /> Existing monitoring wells show that the past discharge from the Ripon Mill has degraded <br /> ground water quality. The Discharger has made substantial improvements in the quality of <br /> wastewater which it discharges. This is a Corrective Action monitoring program, the <br /> purpose of which is to determine whether measures taken by the Discharger are sufficient to <br /> clean up the effects of past waste discharges to ground water and to determine if the <br /> continued discharge of wastewater to land needs to be contained in a waste management unit <br /> described in California Code of Regulations, Title 23, Division 3, Chapter 15 (Chapter 15). <br /> Currently the discharge is not classified as a designated waste due to analysis and <br /> certification by David A. Lawrence, C.E.G. 618. This monitoring program will serve to <br /> verify that decision. <br /> REPORTING <br /> In reporting the monitoring data, the Discharger shall arrange the data in tabular or graphical <br /> form so that the date, the constituents, and the concentrations are readily discernible. The <br /> data shall be summarized in such a manner to illustrate clearly the compliance with waste <br /> discharge requirements. <br /> Monthly monitoring reports shall be submitted to the Regional Board by the 20th day of the <br /> following month. <br /> The results of any monitoring done more frequently than required at the locations specified in <br /> the Monitoring and Reporting Program shall be reported to the Board. <br /> Upon written request of the Board, the Discharger shall submit a report to the Board by 30 <br /> January of each year. The report shall contain both tabular and graphical summaries of the <br /> monitoring data obtained during the previous year. In addition, the Discharger shall discuss <br /> the compliance record and the corrective actions taken or planned which may be needed to <br /> bring the discharge into full compliance with the waste discharge requirements. <br /> SAMPLING AND ANALYSIS PLAN <br /> A Sampling and Analysis Plan shall be submitted to Board staff by 1 July 1993 for approval. <br /> The sampling and analysis plan shall include specific methods for wastewater and ground <br /> water quality, sample collection, handling, chain of custody control, analytical procedures, <br /> and field and laboratory quality assurance and quality control. <br />
