• CY 2010 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. The evaluation of source reduction measures considered the following approaches: • Input changes, • Operational improvements, • Production process changes, • Product re-formulation, and • Administrative steps.
