 Stakebiders involved in developing the Waste Minimization National Plan
       sized the need to prioritize source reduction and recycling based on risk
     •equested a flexible screening tool that would help identify priorities. In
  :sponse, the Agency developed the Waste Minimization Prioritization Tool.
 The list of chemicals with available persistence, bioaccumulation, and toxicity
 data and ranked by the software is known as the Draft Prioritized Chemical List.
 EPA will draw from the chemicals on the Draft Prioritized Chemical List to
 create a National Waste Minimization Measurement List, which EPA will track
 nationally against the goals of the Waste Minimization National Plan and will
 report as part of Government Performance and Results Act reporting.

Chemical rankings were identified by assigning scores to each chemical that represent the
chemical's potential risk to human health and aquatic ecosystems. A chemical's h|fflan health
risk potential score results from adding separate persistence, bioaccurmf
chronic toxicity scores. Similarly, the ecological risk potential score i%
separate persistence, bioaccumulation, and ecological toxic^^ores^

    rtarger differengFin chemical scores (e.g., 18 vs. 12) are more significant than smaller
   ferences (e.g.J^ys. 15). To illustrate, dioxin has an overall score of 18; benzene has an
    r^'sco|e;^P< Dioxhi may pose a greater risk to human health and the environment than
 blnz^n|,r"i|ow;ever, even chemicals that are assigned relatively low scores should not be
           as risk-free, since any chemical may be harmful under certain conditions.
 Further, the chemical rankings can complement, but should not be viewed as replachlg, existing
 lists of regulated chemicals, which are an important means of identifying source reduction and
 recycling priorities.

-------
In addition, since only chemicals with readily available data for persistence, bioaccumulation
potential, and human and ecological toxicity were scored and included on the list, some
chemicals of interest to users may not appear on the list.  The fact that a chemical does not
appear on the list should not be interpreted as meaning that it is not a concern.
