Loads delivered in smaller, self haul vehicles <br /> are recorded by volume. Therefore, it is necessary to calculate <br /> a factor to convert the cubic yard volume of smaller vehicle <br /> non-weighed waste to tons. In developing this conversion <br /> factor, it is assumed that waste delivered to the Lovelace TS <br /> in small vehicles is comparable to the small vehicle waste at <br /> other County sites. Thus, the conversion factor calculated for <br /> the Lovelace Transfer Station -is applicable to other sites for <br /> similar vehicle type non-weighed waste. <br /> This factor was calculated as follows: <br /> Total outgoing tons 1993 136,733 <br /> Less: Weight of incoming weighed waste --97,595 <br /> Equals: Weight of non-weighed incoming waste. 39, 138 <br /> Divided by: cy volume of incoming <br /> non-weighed waste 150,475 <br /> Equals: Conversion factor for cy to tons .2601 <br /> The .2601 factor, or 520 pounds per cubic yard, is used in this <br /> report to convert non-weighed smaller vehicle type waste to <br /> tons for the Foothill and North County Landfills. This <br /> conversion factor is based on annual data. Monthly conversion <br /> factors are used in some cases, which creates some minor <br /> variations in data. <br /> 4 <br />
