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 33W« 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: Prioritization Tool to generate a Draft Prioritized Chemical List, discussed below. The software also includes partial data seta for an additional 3800 chemimls. H. Waste Minimization Prioritization 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 substitute for one another within certain chemical and technology USB,ca.te80"ea8, (e g.. solvents that can be used for metal 237 g-TefracWorodibenzo-p- ' ' dioxin Human Health Ri* Potential: Persistence.— - Bioaccumulation - Human Toxidty — Ecological Risk Potenfcal: Persistence - Bioaccumutottoo Aquatic Toxicity — Overall Score . Score 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. depending on user needs. Complete date sets (i.e., data sets for human toxicity, aquatic toxicity, persistence, and bioaccumulation potential) existed for nearly 900 • chemicals, which were then ranked in me Waste Minimization P™?*"*"" 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 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 Prioritized Chemical List.
