CAR ORGANIZED COLLEC ION REDUCE ENVIAURMSli,LL .rnt:+ a PUBLIC A E4Y? Organized collection does reduce nuisance impacts associated with sev- eral refuse collectors picking up waste on the same block. Organized e collection reduces wear and tear on roads and improves air auallty because fuel consumption is reduced. Organizd collection improves public safety because fewer miles are traveled by garbage trucks thereby decreasing the potential for accidents. The expected life of any street or alley surface is related to the traf- fic which is carried by the street or alley. The roadway surface is particularly affected by heavy wheel loads. The erract an a roacway CT One refuse truck is equivalent t0 1,:00 automobiles. This figure has been documented by the Research Section of the i4lnnesota Department of Transoortaticn (un/DOT) and is currently used by Mn/COT in street anc highway design. In its organized collection effor:S, St. piul estimated to what deIgree the life of a street can be extended if refuse collection '-mere Organ- ized. The city assumed that if Under the current system, where each household arranges for collection, traffic 'volume en a given street is 500 cars per day and five refuse "ticks per week, the ecaivalent traf- fic on the street amounts to 11,:CO cars per week. Under an organized collection system with only one .refuse tru-c:k per 'week, the equivalent traffic On the street is S,CCO cars per week. The cpmpdrisari shows that the effect on the roadway by triif'c may be substantially reduced. Realistically, all streets might Mt last substantially longer under an organized collection system because roadway life is de:endent "pan many other factors than trarfic. However, trafr,c does have a si;nlfican: effect upon roadway life. These addit.'Onal roadway costs are externei costs passed an the the city as a c9nsacuence of each household irrang- ina for refuse count:Tan. The reduced mileage that -efJsa trucks travel can reduce the p0 tertial .lumbar of accidents invol'virg garbage trucks. Reducing the number miles gaveled by aarbage trucks reduces traffic ccngestian and may reduce tv`e nurber of accidents. Emissions of air pollutants would be reduced because garbage trucks would reduce total milaage, the preclse reduction in Pollutd.lts as a result 'Of moving to an organized co•iar-ion system is difficult tc oredict because there are be:h gasaline and diesal powered cOilec:ion vehicles, and it is difficult to estimate the reduction in traffic Congestion and :riles traveled by garbage trucks that would. be achieved by organized collection.

O} Organized collection is one of several methods that could improve neighborhood aesthetics. It could eliminate the unsightliness of containers set out for collection sometimes every day of the week on some blacks. Organized collection could discourage illegal dumping and stockpiling of unwanted and unsightly items in backyards because the costs of removal are generally extra where a household arranges for pilingtcouldicontribute toupublicRhealtheducin9andesafety dumping and stock- � G �G,,' RovA etrapallia� fi
