MONITORING AND REPORTING PROGRAM NO. R5-2003-0049 5 <br /> FORWARD INC AND ALLIED INDUSTRIES <br /> FOR OPERATION OF <br /> FORWARD CLASS II LANDFILL <br /> SAN JOAQUIN COUNTY <br /> Inter-well concentration limits used at Austin Road landfill detection monitor <br /> wells are summarized as follows: <br /> Parameter unit Concentration Limit <br /> Temperature °C 21.25 <br /> Specific Conductance umhos/cm 1236 <br /> pH Units 6.64-8.408 <br /> Turbidity NTU 126.6 <br /> TDS mg/l 997.2 <br /> Chloride mg/1 79.91 <br /> Sulfate mg/1 153.5 <br /> Nitrate as N mg/1 125 <br /> A procedure has been established to evaluate progress of corrective actions at <br /> Austin Road landfill. The procedure is described in detail in Evaluation <br /> Procedures for Porplosed Corrective Action at Austin Road Landfill(February <br /> 2002)by Herst and Associates, Inc. A Total VOC Mass Threshold Limit (41.85 <br /> kg) and Total VOC Threshold Limits for individual wells have been established. <br /> If either of the two types of threshold limits is exceeded and verified, the <br /> corrective action program is re-evaluated to determine if changes to the corrective <br /> action plan are necessary to meet the cleanup goals. Threshold limits for the <br /> proposed new well will be established from background data collected from those <br /> wells. <br /> 4. Point of Compliance <br /> The point of compliance for the water standard at each Unit is a vertical surface <br /> located at the hydraulically downgradient limit of the Unit that extends through <br /> the uppermost aquifer underlying the Unit. For the foreseeable fixture the point of <br /> compliance for old Forward area is the downgradient margin of old Forward <br /> WMUs, and the point of compliance for Austin Road area is the downgradient <br /> margin of Austin Road Landfill <br /> 5. Compliance Period <br /> The compliance period for each Unit shall be the number of years equal to the <br /> active life of the Unit plus the closure period. The compliance period is the <br /> minimum period during which the Discharger shall conduct a water quality <br /> monitoring program subsequent to a release from the Unit. The compliance <br /> period shall begin anew each time the Discharger initiates an evaluation <br /> monitoring program. <br />
