Forward Landfill, Solid Waste Facility Permit(SWFP)Soil Definition Dear Robert: This documents outlines the criteria used to define soil delivered to Forward Landfill as either "Contaminated Soil" (waste that counts against the SWFP tonnage cap), or "Soil Material" (also referred to as "Clean Soil,") that does not count against the tonnage cap. We are submitting letter to you, as suggested in a meeting with you and CIWM B representatives, in an effort to resolve our past differences of opinion as to what types of soil materials should count towards the SWFP tonnage cap, and which should not. It is important to note that Forward Landfill personnel have been reporting contaminated soil as "Class 1I Soil." You have advised us that this subject is now only an SWFP-tonnage- cap issue that is not related to water quality concerns. Since the Class IT designation for soil, or any other material proposed For disposal at Forward Landfill, is a water quality issue, using a term, other than"Class II Soil,"is probably appropriate. For the remainder of this letter, the term "Contaminated Soil,".will be used to identify soil that we are willing to agree should count against the SWFP tonnage cap and "Clean Soil,".to identify soil that does not count against the tonnage cap_ Contaminated Soil may be diverted from disposal and used for such beneficial uses as daily and intermediate cover, road and cellconstruction, drainage and. grading improvements, gas system construction or tipping pad construction. If a particular load, or"batch"of Contaminated Soil (aka"project,"or"event job") is not a Class 1J waste(ie. "Designated Waste'), as detennined by the Regional Water Quality Control Board (RWQCB), then it could be used outside of the lined cell but would still be counted against the daily tonnage cap. Forward Landfill personnel may use CIean Soil.for any use including those listed for Contaminated Soil, either inside or outside a lined cell. Basically, there are three criteria that Forward Landfill personnel will use to determine if soil is Clean Soil or Contaminated Soil. The following text discusses these criteria in more detail. In addition, this letter also gresents a brief description of the process to _ _evaluate soil and determine the appropriate category: — n
