The operations procedures for each of the types of ADC that will be used at Forward are described later in this section. Soil generated from the excavation of each phase of the landfill will be utilized for daily cover or saved for final cover. However, the actual amount of soil used for daily cover will be variable based on the amount of ADC material that arrives at the site. Section 5.2.5 discusses fill phasing and Drawing 5 shows the phasing plan from which any cover soils will be generated. Section 5.3.1 - Soil Balance, discusses the soil quantity availability by phase for the life of the landfill. Any deficiency in onsite soil materials will be reconciled through the use of ADC. Any available ADC materials will be used for daily cover and excavated stockpiled onsite soils will be used to supplement the ADC materials to ensure proper daily cover. ADC will be stockpiled near the working face. Stockpiles will not be maintained for any significant amount of time. Forward manages the ADC stockpiles in a manner that prevents fires, vectors, or other nuisance factors and inadvertent composting. The placement procedures for each type of ADC that is currently utilized or planned to be used at the site are as follows: Processed Green Material (PGM): Green materials received at the landfill may be processed on-site or pre-processed PGM received at the landfill is used for moisture/erosion control and/or ADC. A spotter/laborer diverts customers with wood or green waste loads from the access road to a designated area where the PGM is off-loaded by the customer. On-site staff also monitors the off-loading to Forward Landfill JTD 6-8 J:\Allied\Forward\TD Amendment\Final JTD AmendmentUTD Rev Sec 6 080105.doc:5/22/02 Rev.1:7/2002:Rev.2:4/2003;Rev 3:6/2003, Amendment No.1:8/1/2005
