40 <br />do <br />i <br />• <br />tires. An important aspect of this operation is to continue to qualify for grant <br />funding from the State of Florida. In 1997, 406 tons of tires were processed; 361 <br />tons were used for fuel and 40 tons were shredded for disposal in the landfill. <br />■ Household Hazardous Waste Processing <br />The SWDD has a full time chemist and assistant that collect hazardous waste that <br />residents leave at the five collection/recycling centers. This material is safely and <br />properly stored in the hazardous waste building on a daily basis. When sufficient <br />material is collected, a contracted, licensed hazardous waste hauler packs and <br />manifests the material; then transports it to disposal facilities for proper disposal. <br />All of the collection centers are equipped with used oil collection tanks for oil <br />filters, tubs for household and automotive batteries and biohazardous containers <br />for needles. This is a separate activity which could be contracted out in its <br />entirety, although this is not a large operation. This operation could also be <br />combined with the recycling operation if necessary. <br />Environmental Monitoring <br />Environmental Monitoring is conducted by Indian River County staff, a private <br />laboratory and consulting firms. Although this function could be Completely <br />privatized, it is in Indian River County's interest to maintain control of this <br />activity. The County is ultimately responsible for any contamination at the <br />landfill. Groundwater monitoring wells, surface water staff gauges and gas wells <br />are monitored as required by FDEP Operating Permits and reports are prepared as <br />required by the regulations. <br />■ Scalehouse Operations <br />Indian River County staff weigh every vehicle which enters the landfill to dispose <br />of solid waste. A data management system is used to distinguish types of waste <br />and to track the quantity of incoming waste. Reports are generated from this data <br />system which are used by Indian River County for invoicing purposes and for <br />reports submitted to FDEP. CDM recommends that this function also be retained <br />by Indian River County. <br />■ Air Curtain Incineration <br />An air -curtain incinerator is operated at the landfill for yard waste and land <br />clearing debris which is not mulched. The mburned materials bued are typically trees and <br />brush. About 6,816 tons of vegetative debris were incinerated in 1997. The ash <br />1[on-, the ificinerator is used in the landfill a� covcr material. This operation CvUld <br />be combined with another operation - like C & D processing or it could be shut <br />down. This incinerator is only used part time and with the contract yard trash <br />operation is not essential. <br />Another alternative which should be considered is the combination of a number of operations <br />under one Contract Operator. This should be evaluated during the screening process of the <br />individual operations. A Contract Operator may be interested in assuming operation of most or <br />all the solid waste activities at the landfill. <br />1,11193 ..,,1 B -4 <br />
