Commingled recyclable material is deposited on the MRF tipping floor either from the commercial <br />side or the self haul side. Upon reaching the tipping floor, materials which are hand sorted will be <br />pushed by a loader to recycling bins located beneath a "Z" wall at the south end of the station. <br />The remaining refuse is pushed into transfer trucks through a Loading Chute, an opening in the <br />north side of the tipping floor. Refuse entering the waste stream from the Self -Haul side is <br />unloaded by the customer from the vehicles under the scrutiny of refuse workers assigned to the <br />area. Electronic waste, tires and household hazardous wastes are set aside prior to reaching the <br />tipping floor and relocated to the appropriate staging area for dismantling and processing. <br />3.2.1.1 White Goods <br />White Goods including refrigerators and other appliances are unloaded by customers at the <br />White Goods / Appliances Staging Processing Area (Figure 4) at the south end of the Public Self <br />Haul Disposal Area. Refrigerant is removed from refrigerators and freezers by a private <br />contractor before units are processed as White Goods. <br />3.2.1.2 Refrigerant <br />LTS uses a Refrigerant Extraction Contractor to comply with State Law requiring that certain <br />items in the refrigerant waste stream receive special handling and processing prior to recycling. <br />Wastes to be removed include Freon and other refrigerants, Polychlorinated Biphenyls (PCBs), <br />mercury switches and temperature sensing devices, and gasoline. Items such as refrigerators, <br />freezers, A/C units, drinking water dispensers, and commercial food display units can contain <br />refrigerants. Refrigeration units can contain any one of many refrigerants, Chlorofluorocarbons <br />(Freon) R-12, R-221 <br />R-134, R-30 are the most common. Older units and units removed from <br />recreational vehicles may contain ammonia. Although extremely rare, the facility occasionally <br />has received very old refrigerant containing methyl chloride which poses an extreme hazard to <br />personnel. <br />Due to the level of technical understanding required, and potential for injury, refrigerant removal <br />may only be performed by certified trained employees. Refrigerant training includes the <br />instruction of proper operation of evacuation equipment, and "Operator Certification" for <br />Id refrigerant removal. An employee must pass a State certified Freon removal written exam and <br />Lovelace MRF and Transfer Station Department of Public Works/Solid Waste Division <br />Transfer Processing Report County of San Joaquin <br />April 10, 2015 21 <br />
