Basso <br /> Forward Inc. <br /> Post Office Box 6336 <br /> Stockton.,, CA 9520E <br /> REVIEW OF POTENTIAL WASTES FOR 'FORWARD LANDFILL, .SAN JOAQUIN COUNT' <br /> (CASE NO. 2209) <br /> I received a letter from Dan Maglionico of Eljumaily-Butler Associates dated <br /> 6 April 1988. In that letter he describes three waste streams and asks if the <br /> materials are suitable for disposal at Forward Landfill. All of the wastes can <br /> be disposed of at Forward as long as the following conditions are met: <br /> Caustic Soil from Quaker Oats in Oakland: <br /> . This soil can only be used in the foundation layer of the final cap for WMU <br /> A. <br /> Bottom Ash from the Modesto Energy Tire Burner: <br /> . Based on the WET data, this waste is definitely a `designated waste' and <br /> can only be disposed of in a Class II waste management unit (WMUI. If <br /> additional WET analyses using deionized water show significantly lower <br /> metals concentrations and the bottom ash has no net acid generating <br /> potential , then a Class III monoili may be a suitable option. If the <br /> Class II route is taken, then Waste Discharge Requirements (WDRs) will have <br /> to be rewritten to allow other than coal or wood ash into WMU E. If the <br /> Class III option is chosen, it is probable that only a new operations plan <br /> would have to be submitted with no revision to the existing WDRs. <br /> Qypsum from the Modesto Energy TireBurner: <br /> . Since this waste is soluble in an acidic environment and would generate a <br /> leachate high in total dissolved solids and electrical conductivity, it is <br /> not suitable for codisposal in a Class III WMU. An alternative would be <br /> disposal in a Class III monofili, possibly with the bottom ash. <br /> If Forward does decide to accept either the bottom ash *or the ,gypsum, design <br /> reports describing the intended method of disposal and any construction should <br /> be submitted to the Regional Board for approval before construction takes place <br /> or the waste is accepted on-site. <br />
