'i� Category C waste streams were all the routine extremely hazardous waste streams. Major Category C waste streams were CWC -identified waste streams that consisted of five percent or more of the total Category C waste streams. Table 4, Major Category C waste streams 6CIAC; aced In CY 2014 Jul each Site Quantity in pounds As mentioned above these I�t7E•sites are primarily research and development facilities. Each site generally contains many small laboratories that conduct academic research. The research projects vary in duration and span a wide variety of areas. In contrast to manufacturing facilities or continuous processes, the waste generated is varied and . sometimes in small quantities. Therefore, even though this document breaks down the waste streams based on CWC, as required by the regulations, the quantities of waste within one waste code category could be fi•om many different locations and dissimilar processes. Because of the nature of work at the sites, it is not always economically feasible to try to implement source reduction measures for every process that generates a portion of the identified major waste stream. This document identifies those processes that generate major portions of the waste within an identified major waste stream and evaluates source reduction opportunities for the waste generating process. Many of the activities that generate hazardous waste under a specific CWC are fr om different processes, as well as from many different users. To help focus on reducing major hazardous waste streams in a systematic approach, SLAC applied the Pareto Principle to filter out its larger waste -generating departments associated with major'waste streams. The Pareto Principle helped identify the top 20 percent of the SLAC departments that generated 80 percent of the hazardous waste. The top waste -generating departments were given additional review to determine how they contributed to the generation of the major waste stream. If there.were many small generators of a given major waste stream, consideration was also given to providing a generalized measure that could apply to aII of these generators, rather than trying to be process-, operation-, or activity -specific. The Plan part of this document is organized by CWC; and where possible the common information about a particular CWC for different sites has been described in one section.
