t <br /> existing and proposed fencing. <br /> 6. Provide a run-off analysis for sheet and rill erosion to <br /> predict the soil loss or potential loss under various <br /> conditions. (17779 (h) ) . <br /> 7. it is agreed that leachate collection and treatment is not <br /> required by Title 23, Subchapter 15, section 2543 at an <br /> unlined class III landfill that does not accept sewage or <br /> water treatment sludge. Leachate monitoring however, is a <br /> separate issue. <br /> The operator did provide a report (Kleinfelder, 1/22/91) that <br /> concluded, based on modeling, the groundwater would not be <br /> impacted by leachate for at least 25 years. Periodic <br /> monitoring for leachate would be advisable to confirm the <br /> findings in Kleinfelder's report and ensure that leachate is <br /> not being produced in greater quantity and moving more rapidly <br /> than anticipated. <br /> 8. The operator will need to revise section 2. 1 of the <br /> Postclosure Maintenance Plan, section 3: 1 of the Summary of <br /> Reporting Requirements, section 5.4 of Maintenance and <br /> Monitoring, and section 2. 0 of Final Postclosure Maintenance <br /> Costs if leachate monitoring is required. <br /> 9. The gas monitoring plan for Harney Lane Landfill has been <br /> reviewed by CIWMB staff .an San Joaquin county Environmental <br /> Health Division. Upon final approvalt the revised plan will <br /> need to be incorporated into the Final Closure/Postclosure <br /> Maintenance Plan. Each section of the Plan that addresses gas <br /> monitoring, including figure 13, will need revision, as <br /> necessary, to parallel the approved revised gas monitoring <br /> plan. <br /> 10. The amount allocated for revegetation in the' closure cost <br /> estimates seems low when compared to example closure costs <br /> given in March, 1990 Waste Age Magazine (table two, page 41) . <br /> Harney Lane's closure estimate for the landfilled area is <br /> $380.00 per acre while example estimates for seed, fertilizer, <br /> and mulch range from $1000-$1500 per acre. <br /> 11. Mr. Rodriquez's name should be removed from the CQA management <br /> team as he is no longer an employee of the County solid waste <br /> division. <br /> 12. The slope stability report does not appear to have been <br /> prepared in accordance with California Division of Mines and <br /> Geology notes 142 and 144 . The seismic elements called for in <br /> 'the. CDMG notes and required by 17777 (C) (1) (A-C) are not <br /> addressed. <br /> 13 .
