TENTATIVE MONITORIN&AND REPORTING NO. r./ -�- FOR CLOSURE,POST CLOSURE AND CORRECTIVE ACTION OF SURFACE IMPOUNDMENTS AT KRUGER FOODS, INC - SMS BRINERS VEGETABLE BRINING FACILITY SAN JOAQUIN COUNTY aquifer and any permanent or ephemeral zones of perched groundwater underlying the facility. - Include a map showing the monitoring points and background monitoring points for the surface water monitoring program, and the groundwater monitoring program. The map shall include the point of compliance in accordance with §20405 of Title 27. - Evaluate the perennial direction(s)of groundwater movement within the uppermost groundwater zone(s). If subsequent sampling of the background monitoring point(s) indicates significant water quality changes due to either seasonal fluctuations or other reasons unrelated to waste management activities at the site, the Discharger may request modification of the Water Quality Protection Standard. MONITORING Ground Water The Discharger shall operate and maintain a groundwater detection monitoring system that complies with the applicable provisions of§20415 and §20420 of Title 27 in accordance with a Detection Monitoring Program approved by the Executive Officer. The Discharger shall collect,preserve, and transport groundwater samples in accordance with the approved Sample Collection and Analysis Plan. Within each Semi-Annual report, the Discharger shall determine the groundwater flow rate and direction in the uppermost aquifer and in any zones of perched water and in any additional zone of saturation monitored pursuant to this Monitoring and Reporting Program, and report the results semiannually, including the times of highest and lowest elevations of the water levels in the wells. Hydrographs of each well shall be submitted showing the elevation of groundwater with respect to the elevations of the top and bottom of the screened interval and the elevation of the pump intake. A map of the potentiometric surface,which includes all wells from similar water bearing zones, shall be prepared quarterly and submitted semi-annually. Groundwater samples shall be collected from the point-of-compliance wells, background wells, and any additional wells added as part of the approved groundwater monitoring system. Samples shall be collected and analyzed for the monitoring parameters in accordance with the methods and frequency specified in Table I. The monitoring parameters shall also be evaluated each sampling event with regards to the cation/anion balance, and the results shall be graphically presented using a Stiff diagram, a Piper graph, or a Schueller plot. Samples for the constituents of concern specified in Table I shall be collected and analyzed in accordance with the proper EPA method.
