LLNL-AR-788093 External Many of the activities that generate hazardous waste under a specific CWC are from 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 all 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. The CWC-specific sections include the following information: • Generating site(s), • Calendar year 2018 waste generation quantities in pounds (lb), • A block process or flow diagram for waste generating and/or handling processes, • A narrative explanation of the generating process including identification of hazardous characteristics and hazardous constituents where necessary, • An explanation of waste reduction/pollution prevention activities to date, • An evaluation of planned waste reduction/pollution prevention activities for the next four years. Where appropriate, each waste reduction/pollution prevention activity evaluation includes the following: • Description of source reduction measure, • Technical feasibility, • Economic feasibility, • Evaluation of effects in product quality, • Evaluation of effects on employee health and safety, • Federal, state and local regulatory agency requirements, • Discussion of releases and discharges, • Evaluation of effects on land, water and air, and • Schedule for implementation.
