Appendix A
Priority Lists of Chemicals
A master list of approximately 1,000 acutely toxic chemicals was initially compiled through the integration of individual priority lists of chemicals submitted by each U.S. federal agency placing a representative on the NAC/AEGL Committee. The master list was subsequently reviewed by individuals from certain state agencies and representatives from organizations in the private sector and modified as a result of comments and suggestions received. The various priority chemical lists were compiled separately by each federal agency based on their individual assessments of the hazards, potential exposure risk, and relevance of a chemical to their programmatic needs.
On May 21, 1997, a list of 85 chemicals was published in the Federal Register. This list identified those chemicals to be of highest priority across all U.S. federal agencies and represented the selection of chemicals for AEGL development by the NAC/AEGL Committee for the first 2–3 years of the program. The committee has now addressed most of these chemicals, and they are currently in the “proposed,” “interim,” or “final” stages of development. Certain chemicals did not contain an adequate database for AEGL development and, consequently, are on hold pending decisions regarding further toxicity testing. This initial “highest” priority list of 85 chemicals is shown in Table A-1.
A second “working list” of approximately 100 priority chemicals is being selected from the original master list or from new high-priority candidate chemicals submitted by U.S. agencies and organizations and by member coun-
tries of the Organization for Economic Cooperation and Development (OECD) that are planning to participate in the AEGL Program. Although “working lists” will be published in the Federal Register and elsewhere from time to time to indicate the NAC/AEGL Committee’s agenda, the priority of chemicals addressed, and, hence, the “working list,” is subject to modification if priorities of the NAC/AEGL Committee or individual stakeholder organizations, including international members, change during that period.

The initial list of 85 priority chemicals shown in Table A-1 has been created by identifying the highest priority hazardous chemicals from the Master List. This initial list is a starting point for the development of AEGL values by the National Advisory Committee for Acute Exposure Guideline Levels for Hazardous Chemicals (NAC/AEGL). However, the list of chemicals is subject to modification, pending changes in priorities recommended by the various stakeholders that make up the NACa/AEGL. While it is anticipated that most of these chemicals will remain as high priority for AEGL development, changes to the list could occur. The NAC/AEGL Committee hopes to select 30 to 40 chemicals per year to address in the AEGL development process. Consequently, the initial list will expand as the NAC/AEGL Committee continues to address chemicals of interest to its member organizations. |
