4.3.1 MATERIALS ACCEPTED FOR BENEFICIAL REUSE The Forward Landfill accepts materials for beneficial uses such as alternative daily cover (ADC), wet weather deck preparation, internal haul road improvements and earthen drainage control improvements. The average and maximum needs in tons for each beneficial reuse material accepted at the Forward Landfill are as follows: MATERIAL TYPE AVERAGE NEEDS MAXIMUM tons da NEEDS tons da Green Waste and Com ostable Material ADC 206 669 Contaminated Soil 1,546 3,287 Beneficial Inerts* other than soil) 133 475 Ash and Cement Kiln Dust ADC 20 172 Treated Auto Shredder Residue ADC 205 1,368 Other ADC Materials e. . shredded tires 54 157 Beneficial inert materials include concrete,asphalt, roofing tile,and other rock/aggregate-basedmaterials. (1) Beneficial inerts after processing are mainly used on-site for uses other than C&D ADC. Forward Landfill will document use of C&D ADC in their site records when utilized. The volume of this material is,therefore, a subset of the average and maximum needs listed above. It should be noted that in no event will any combination of the above-listed beneficial use materials and refuse exceed the maximum daily limit of 8,668 TPD. To establish the limits for the materials shown above, Forward reviewed 2005 weight and volume records, which provided the maximum daily need for each material. Additionally, the 2005 total for each material was also divided by the permitted number of working days per year to establish the average daily need. Forward also conducted field tests at the landfill to determine refuse-to-cover ratios and in-place densities for those beneficial re-use materials utilized as ADC. Forward conducted the test for green waste several years ago and documented the results in a December 20, 2002 letter to Ms. Donna Heran, Director, San Joaquin County Environmental Health Division. Forward conducted the test for treated auto shredder residue in December 2005. In addition, the following procedures were used to provide control for those field tests conducted: 1) a specific ADC material is weighed and loaded into a dump truck; 2) a dozer then spreads the ADC material over the designated field test area (which is measured in square feet); 3) the ADC material is compacted to the minimum required thickness in accordance with 27 CCR or as approved by the LEA; and 4) using the recorded weight of the material, it is determined how much ADC material (in tons) was used to cover the measured test area (in square feet). The results from these tests were utilized to Forward Landfill JTD 4-8 J:\Allied\ForwardUTD Amendment\March 2006 JTD.LEA RespUTD\JTD Sec 4 Final.doc: BRYAN A.BTIRRAT&ASSOCIATES 05/24/02;Amendment No. 1: 5/19/2006
