Where the size of the bins is a factor is in primarily two categories collection of the waste from <br />residences and disposal of the waste. Recology performs these tasks and charges the City for doing so. <br />Costs for these are dependent upon the volume of waste (and recyclables) that gets collected then <br />processed. Collection requires that Recology initially provide bins (this could be a fixed cost to <br />Recology) and collection requires a truck and at least one operator. One might be inclined to think that <br />it takes fewer stops to fill a truck when collecting the largest bins because it takes fewer stops and less <br />mileage fill the truck. For example, suppose a truck can hold 9600 gallons of garbage, it can service 100 <br />customers with 96-gallon bins making fewer stop and travelling less than to collect the same amount of <br />waste from 20-gallon bins. That requires 480 stops. That’s more stops and more mileage to collect the <br />same amount of garbage from the smaller bins. Thus, the tendency is to think it costs more to pick up <br />smaller bins. However, that’s not quite true. Service is to individual customers. To illustrate why likely <br />it costs more to service larger bins, let’s assume each truck carries only 1000 gallons of waste and each <br />route is 50 customers. In the extreme case one truck can service the 50 customers with the smallest <br />bins with one trip, while it takes five trucks to service and five operators to service the same number of <br />customers with the largest bins (one truck would only be 80% full). Additionally, processing the waste <br />of those customer’s waste at the service center and the disposal size costs more just because there’s <br />more waste (there’s no reason that waste collected from a 20-gallon bin costs more per gallon than <br />that from the 96-gallon bin once it reaches the service center.) The cost to Recology to process and <br />dispose of 9600 gallons of waste is the same whether it comes from 96-gallon bins or 20-gallon bins. <br />Individual customers should be equitably charged for the amount of waste they dispose. <br /> <br />Certainly, the City and Recology individually know their fixed costs for maintaining accounts and <br />service. Recology knows it’s costs for bins, truck, and other equipment, fuel, personnel, etc. <br />Additionally, Recology knows how much it costs them to process the collected waste and depose it. <br />Those costs can be determined as averages per gallon. Fixed costs similarly can be averaged by <br />numbers of accounts, while those that vary with the size of bin can be averaged by volume. If users of <br />96-gallon bins were charged $1.94 per gallon as your proposal charges those with 20-gallon bins, then <br />perhaps paying $186.24 rather than the proposed rate of $107.31, might encourage customers to be <br />more conservative and careful about solid waste and its effect on the environment. Thus, a rate <br />structure for solid waste can be established which encourages conservation by charging those the <br />waste more than those that conserve, just as the City’s rate structure for water use does. I strongly <br />encourage the council to rescind the proposed rate increases and consider an alternative which not <br />only encourages conservation, but is more equitable. It can be applied later. <br /> <br />Sincerely, <br /> <br /> <br /> <br />Kathy Maher, Ph.D. <br />1584 Hudson Street <br />Redwood City, CA 94061-2989 <br /> <br />Enclosure: Inequities Redwood City Proposed Water Rates 2025.pdf
