SUPPtEMEMTARY INFOfaftATTON:
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
goals:
(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
2005.
(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
follows:

Prioritized Chemical List, discussed
below. The software also includes
partial data seta for an additional 3800

Tool
The Prioritization Tool is a Windows-
based computer program that houses-
available persistence, bioaccumuLmon.
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
Tool
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
relative risk of chemicals that am

human toxicity, aquatic toxicity,
persistence, and bioaccumulation
potential) existed for nearly 900 •

Tool EPA used the Waste Minimization
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
Crosswalk
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

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
Prioritized Chemical List. The Draft
