weigh more than un-compacted loads of the same volume. Therefore, weighing waste is a more accurate method of recording waste quantities. However, this method does require a scale system to weigh the vehicles bringing waste to the sites. Not all of the disposal facilities in San Joaquin County have scales to weigh incoming waste. The County's North County Recycling Center And Sanitary Landfill, Foothill Sanitary Landfill, and Lovelace Transfer Station have scales. These scales are computerized and the system provides a significant amount of information concerning the waste stream, based on both weight and volume. The City of Stockton has scales at its Austin Road Sanitary Landfill and its French Camp Sanitary Landfill. Information for the other disposal facilities is based on volume and is more general in nature. C. OVERALL CONVERSION FACTOR: For those disposal sites in the County with no scales, a conversion factor to convert cubic yards to tons was developed using data compiled at the Lovelace Transfer Station. The conversion factor assumes waste types received at the Lovelace Transfer Station are similar to those at other disposal facilities in the County. The Waste Characterization Studies performed in 1990 generally indicate that waste types are similar throughout the County. All waste is transported from the Lovelace Transfer Station in transfer vehicles, which are weighed as they leave. The conversion factor was calculated by dividing the total tons leaving the transfer station during 1994 (137,139 tons) by the total cubic yards received at the transfer station during 1994 (714,299 cy) The result, .1920, is the conversion factor used in this report to convert cubic yard data to tons for the Corral Hollow Sanitary Landfill which has no scales. The .1920 conversion factor is equivalent to 384 pounds per cubic yard. This conversion factor varies from year to year, as the following table indicates. 3
