_ ENV/RONMENTAL <br /> TECHNOLOG/ES <br /> Methodology for Waste Classification and Cleanup level Determination" by Dr. Jon Marshack, <br /> 1 dated June 1989. <br /> Examples of Type III soils include non-hazardous soils containing PNAs, chlorinated pesticides <br /> and solvents, alcohol, ketone and aliphatic and aromatic contaminated soils, if no designated <br /> levels are indicated in WDR 89-148. However, when site specific designated levels have been <br /> established and approved by the regulatory agencies, such contaminated soils may be reclassified <br /> as Types I or II soil. <br /> 3.4 Type IV Soils: Special Class II Soils 1, <br /> These are contaminated soils that may be classified as hazardous, but have an accompanying <br /> variance from the DOHS, thereby waiving the hazardous classification. Additionally, these <br /> Type IV soils will include soils that are currently classified as designated waste, but require the <br /> specific approval of the RWQCB for reclassification as a non-designated waste, or special <br /> 1 requirements prior to acceptance as a Class II designated waste. Examples of such a waste <br /> would include Type III soils containing chemicals at concentrations above the their designated <br /> ' levels. Type IV soil may require storage/treatment and post-treatment disposal at a WMU. <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 7255 Soroni Drive•Oakland,California,USA 94611 <br /> TEL(415)339-1543-FAX(415)339-6775 <br />
