AR TIVE <br /> III. IDENTIFICATION OF CALCULATION METHODS <br /> An Excel spreadsheet was created to identify the major hazardous waste streams <br /> and the total quantity of hazardous waste routinely generated at the facility, The <br /> Excel spreadsheet is referred to as Hazardous Waste Data 2002. It includes the <br /> waste stream description, California Waste Codes (CWCs), federal waste code, <br /> frequency of generation (routine or non-routine), weight of each waste stream in <br /> pounds, total SB 14 qualifying wastes, and the total of all wastes generated at <br /> the facility. This information was obtained from the facility's hazardous waste <br /> manifests. The Hazardous Waste Data spreadsheets from 2002 can be <br /> referenced in Appendix A. Accurate waste generation data is not available prior <br /> to 2002. <br /> The Hazardous Waste Data from 2002 were reviewed and wastes were identified <br /> as being exempt or qualifying as SB 14 hazardous wastes. The exempt wastes <br /> were eliminated from the SB 14 total used in this Hazardous Waste Management <br /> Performance Report. The list of wastes that were exempted under the Hazardous <br /> Waste Source Reduction and Management Review Act of 1989 (SB 14) are as <br /> follows: <br /> • Non-routinely generated wastes <br /> • Motor vehicle fluids and motor vehicle filters <br /> • Lead-acid batteries <br /> • Lighting wastes including ballasts and fluorescent tubes <br /> • Asbestos <br /> • Polychlorinated biphenyls (PCBs) <br /> • Demolition waste/renovation waste <br /> Using the Excel spreadsheet created, each individual waste stream is subtotaled. <br /> The weight of all routinely generated waste streams (hazardous waste) on-site is <br /> totaled. These totals are used to identify which of the waste streams exceeded <br /> 5% of the SB 14 total hazardous waste routinely generated at Facility Services <br /> for the reporting and baseline years (2002), refer to Section IV, Table 1. <br /> Stockton Unified School District 6 NETWORK ENVIRONMENTAL SYSTEMS,INC <br /> Hazardous Waste Performance Report <br />
