• 1.0 INTRODUCTION Bryan A. Stirrat & Associates (BAS) was contracted by Allied Waste industries (Allied) to conduct a field dernonstration of Alternative Daily Cover (ADC) materials currently utilized at the Forward Landfill (FL) located in Stockton, California. The goal of the test program was to establish a relationship between weight and as - placed volume (density) of the ADC materials used at the site. This information will help regulators and site operators track usage of ADC and ensure compliance with California Code of Regulations, Title 27, Chapter 3, Subchapter 4, Article 1, Section 20690. Allied agreed to conduct this testing in coordination with the local Enforcement Agency, the San Joaquin County Environmental Health Department (LEA) and the California integrated Waste Management Board (CIWMB). BAS conducted an engineering pre-test on October 3, 2006 to work out logistical details in advance of the scheduled testing. LEA and CiWMB staff were present on October 11 and 12, 2006, when the testing described in this report was conducted. The test program was designed and directed by John Boucher and Eric Tjensvold of BAS. The test was observed by Robert McClellon (LEA), Keith Kennedy (CIWMB), and Lochlin Caffey (Allied), all of whom provided input to the design and operation of the test program. This report was written by Eric Tjensvold and reviewed by John Boucher and Lochlin Caffey. ADC materials tested during this program included shredded greenwaste and treated auto shredder waste (TASW). Results of the shredded green waste and TASW in -place -density testing are included in Section 2. Photographs taken during this program are included in Appendix A. While not originally part of the program, Keith Kennedy of the CIWMB requested that a test plot be constructed for soil daily cover, the results of which are also included in Section 2. The test was designed to mimic actual daily cover placement as closely as possible while allowing for careful measurement and documentation Test plots were laid out on municipal solid waste (MSW) surfaces placed by Caterpillar model D8 and D9 dozers and model 836 waste compactors within Forward's subtitle -D lined disposal area. All equipment was run by the same operators who normally perform these operations, MSW surfaces used for the test were compacted to the point where the compactor would "stand up" on the surface of the MSW, leaving a relatively smooth 1-1 ):\Alried\for\BRYAN A.
