5.0 HAZARDOUS WASTE GENERATION DATA <br /> 5.1 BACKGROUND <br /> This section of the CHWMP presents an analysis of the County' s hazard- <br /> ous waste stream. The waste generation patterns of the major and <br /> small quantity generators are described, and treatment options for <br /> each waste stream are listed. A number of sources were used to com- <br /> pile the data for the hazardous waste generation data presented <br /> herein. These sources included the Department of Health Services <br /> (DHS) and the hazardous waste generators. <br /> The DHS provided the County with a summary of 1985 and 1986 hazardoys <br /> waste generation data specific to the County. This information is <br /> stored in the Department's Hazardous Waste Information System (HWIS) <br /> and is based on Uniform Hazardous Waste Manifests completed by each <br /> generator transporting wastes off site by road or rail . The manifest <br /> is a shipping document on which generators describe their wastes <br /> according to 80 general California waste categories. In order to <br /> simplify the waste classification system for the CHWMPs, the DHS <br /> reduced and combined the manifest categories and selected 17 different <br /> waste groups. For simplicity and consistency, all hazardous waste <br /> generation data in the CHWMP are organized according to these broader <br /> waste groups. The units "tons" and "tons per year" are used in all <br /> data presentations. <br /> The hazardous waste generation data in the CHWMP are organized in the <br /> following waste groups: <br /> • Organic Liquids <br /> Waste Oil <br /> Halogenated solvents <br /> - Nonhalogenated solvents <br /> - Aqueous solutions and other liquids <br /> - Pesticides <br /> PCBs and Dioxins <br /> PJ9 9390502D.00D 5-1 Rev. 1 11/08/88 <br />
