MONITORING AND REPORTING PROGRAM _4_ <br /> WASTE MANAGEMENT OF NORTH AMERICA INCORPORATED <br /> FOOTHILL SANITARY LANDFILL INCORPORATED <br /> FOOTHILL SANITARY LANDFILL FACILITY <br /> CLASS III LANDFILL <br /> SAN JOAQUIN COUNTY <br /> Quarterly samples shall be taken from these wells for one year and analyzed for <br /> each of the parameters and constituents listed under "Ground Water Monitoring" <br /> above. Analyses shall account for measurement errors in sampling and analysis. <br /> The ' one year ' of sampling shall begin the first quarter after the monitoring <br /> wells are installed. The data from these analyses shall be reported to the <br /> Board 13 months after the sampling begins. The data will be used by the Board <br /> in determining water quality protection standards for ground water at the site. <br /> If subsequent sampling of "background" monitoring wells indicates significant <br /> water quality changes due to either seasonal fluctuations or other reasons <br /> unrelated to waste management activities at the site, the Discharger may request <br /> modification of the water quality protection standards. <br /> Statistical Procedures for Determining Significant Increases <br /> The significance of increases in indicator parameters and waste constituents <br /> over water quality protection standards shall be established through the use of <br /> a Board approved statistical procedure. <br /> REPORTING <br /> In reporting the monitoring data, the Discharger shall arrange the data in <br /> tabular form so that the date, the constituents, the concentrations, and the <br /> units are readily discernible. The data shall be summarized in such a manner so <br /> as to illustrate clearly the compliance with waste discharge requirements. <br /> Monthly monitoring reorts shall be submitted to the Board by the 15th day of <br /> the month following the month in which the samples were taken. Quarterly, <br /> semiannual , and annual monitoring reports shall be submitted to the Board by the <br /> 15th day of the month following the calendar quarter in which the samples were <br /> taken. <br /> The results of any monitoring done more frequently than required at the <br /> locations specified herein shall be reported to the Board. <br /> A report shall be submitted to the Board by 30 January of each year containing <br /> both tabular and graphical summaries of the monitoring data obtained during the <br /> previous year. The report shall include a discussion of compliance with the <br /> waste discharge requirements. <br />
