 L Background
   In November 1994, EPA.released toe
 Waste Minimization National Plan
 (National Plan, WMNP). The National
 Plan focuses on reducing the generation
 and-subsequent release to toe
 environment of toe most persistent,
 bioaecumulative, and toxic chemicals in
 hazardous wastes, and establishes three
    (1) To reduce, as a nation, the
 presence of the most persistent,
 bioaecumulative, and toxic chemicals ii
  hazardous wastes by 25 percent by toe
  year 2000 and by 50 percent by toe year
    (2) To avoid transferring these
  chemicals across environmental media.
    (3) To ensure that these chemicals are
  reduced at their source whenever
  possible, or. when not possible, that
  they are recycled in an environmentally
  sound manner.
     Persistent chemicals do not readily
   break down once they are released into
   toe environment Bioaecumulative
   chemicals tend to accumulate in plant
   and animal tissues. Toxic chemicals
   have toe potential to harm ecological
   systems or adversely impact human
   health (e.g., can cause cancer,^
    reproductive, andmutagemc health
    effects). These three characteristics of
    chemicals are considered important
    determinants of toe human health and
    environmental risks associated with
    environmental releases, or potential
    releases, or chemicals. Chemicals that
    are persistent bioaecumulative. and
    toxicT therefore, have toe potential to
    accumulate in toe environment and
    cause harm to human health and the
    environment even when released in
    ^aall amounts. The National Plan seeks
    a voluntary reduction of ^ese  chemicals
     ta hazardous waste so as to reduce toe
     potential for future harm to human
     health and the environment.

                                                                            1997 / Notices
  During development of the Waste
Minimization National Plan,
stakeholders indicated a need for
assistance in setting waste minimization
priorities, specifically, the need for a
JilUilUBa* oypv<****.«" »«j r ——	
flexible screening tool to prioritize
waste minimization activities. EPA
committed in the National Plan to    .
developing a software tool which would
help establish waste minimisation
priorities based on the inherent hazard
of chemicals based on characteristics ot
chemical* in wastes as generated,
specifically oa persistenca,
bioaccumulation, and toxicity
characteristics of chemicals in
hazardous wastes, as well as chemical
quantity. EPA will also use the software
tool to establish national waste
 minimization priorities by selecting
 certain chemicals and measuring
 national reductions in the presence of
 these chemicals in hazardous wastes.
   Today's notice announces me
 availability of: (1) The Draft Waste
 Minimization Prioritization Tool, a
 software package which ranks chemicals
 according to persistence,
 bioaccumulation. and toxicity, and
 allows users to add chemical quantity
 data into the ranking process; (2) The
 Draft User's Guide and System
 BocTunentation: (3) The Draft Pnontized
 Chemical List, a list of chemicals that
  have gone through the persistence,
  bioaccumulation, and toxicity
  Prioritization process and their relative
  Likings; and (4) The Draft Chemical/
  RCRA Waste Code Crosswalk, a
  crosswalk of RCRA hazardous waste
  codes and the chemicals they are likely
  to contain.
decreasing). EPA added a larger subset
of chemicals found in hazardous wastes
into the software's database and made
other modifications to make the Use
Cluster Scoring System more useful as
a waste minimization prioritizatipn tool.
  The persistence, bioaccumulation,
toxicity, and quantity scoring algorithm
is the primary component of the Waste
Minimization Prioritization TooL The
scoring algorithm assigns chemical-
specific scores based on ma chemicals'
potential to pose risk to human health
and aquatic ecosystems. The scoring
algorithm is a screening tool and is not
 intended to be used as a substitute for
 detailed risk analysis. The FrioriiizatioB
 Tool provides a relative risk ranking of
 chemicals rather man an absolute
 measure of risk (i.e., it provide* a
 chemical score or ranking that indicates
 potential concerns relative to other
 scored chemicals);
   Four factors were used to develop tne
 overall chemical score: Human toxicity
  (including cancer and non^cancer
  effects): human exposure potential
  (based on persistence and       ^
  bioaccumulation potential); ecological
  toxicity (determined by aquatic
  toxicity); and ecological exposure
  potential (based on the same score*
  persistence and bioaccumulation
  potential scores as for human exposure
  potential). Sub-scores of 1 (lowest). 2,or
  3(highest) are assigned for each of tE6
  components based on an evaluation of
  chemical data and then summed to
  create an overall score ranging from 18
  (highest) to 6 (lowest). For example,
  dioxin is assigned a score of 18 as
                                                                          Prioritization Tool to generate a Draft

   and human and ecological toxicity date
   and provides a relative ranking of nearly
   900 chemicals based on their
   persistence, bioaccumulation. and
   toxicity scores. The software also allows
   users to import their own data on
   chemical quantities for use in the
    scoring algorithm.
    A, Scoring Aspects of the Prioritization
      The Waste Minimization
    Prioritization Tool was developed by
    modifying the Use Cluster Scoring
    System, which EPA's Office of Pollution
    Prevention and Toxics developed as a
    screening mechanism to rank the

                                           The software also allows users to add
                                         chemical quantity date into the scoring •
                                         algorithm. Because the software is
                                         flexible, a variety of types of chemical
                                         quantity date can be added, ranging
                                         from facility-level data to national date.

B. Supplementary Information in the
Prioritization Tool
  The Waste Minimization
Prioritization Tool also provides
supplementary information relevant to
risk-based decision-making, including
information on which RCRA hazardous
wastes are likely to contain the scored
' chemicals (i.e., Chemical-RCRA Waste
Code Crosswalk), as well as whether the
chemicals appear on other national
environmental regulatory and non-
regulatory lists of concern.
 1. Draft Chemical/RCRA Waste Code
   The Draft Chemical-RCRA Waste
 Code Crosswalk portion of the Waste
 Minimization Prioritization Tool links
 each of the nearly 600 RCRA hazardous
 waste codes with about 500 chemicals
 likely to be found in these wastes. The
 crosswalk feature in the Prioritization
 Tool can be used two different ways: To
  identify RCRA waste codes that are
  likely to contain a particular chemical,
  and to identify which chemicals are
  likely to be found in a particular RCRA
  waste code. EPA used background
  analysis for hazardous waste listing
  rulemakings. Land Disposal Restrictions
  rulemakings, and the proposed
  Hazardous Waste Identification Rule to
  identify linkages between the chemicals
  and RCRA hazardous wastes.
    Hard-copy versions of the Dratt
  Chemical/RCRA Waste Code Crosswalk ,
  can also be obtained through the
  addresses above.
   2. Lists of Concern
     Each chemical in the Waste
   Minimization Prioritization Tool is also
   cross-referenced with seventeen
   regulatory and non-regulatory lists.
   including the Clean Air Act
   Amendments Title m Hazardous Air
   Pollutants, the Clean Water Act section
   307 Priority Pollutants, RCRA section
   3001 Hazardous Wastes, Appendix VIE
   Hazardous Constituents and Appendix
   DC Ground Water Monitoring Lint, and
   RCRA P and U Wastes (261.33).

   3. Draft Prioritized Chemical List
      The list of chemicals with available
    persistence, bioaccumulation. and
    toxicity date and. therefore, able to be
    scored by the Waste Minimization
    Sioriuzation Tool is ^own as the Draft
