The Thirteenth Meeting of the Parties decided:
1. to request the Secretariat to keep the list of new substances submitted by Parties pursuant to decision IX/24 on the UNEP Website up to date and to distribute the current version of the list to all Parties about six weeks in advance of the meeting of the Open-ended Working Group and the Meeting of the Parties;
2. to ask the Secretariat to request a Party that has an enterprise producing a listed new substance to request that enterprise to undertake a preliminary assessment of its ODP following procedures to be developed by the Scientific Assessment Panel and to submit, if available, toxicological data on the listed new substance, and further to request the Party to report the outcome of the request to the Secretariat;
3. to call on Parties to encourage their enterprises to conduct the preliminary assessment of its ODP within one year of the request of the Secretariat and, in cases where the substance is produced in more than one territory, to request the Secretariat to notify the Parties concerned in order to promote the coordination of the assessment;
4. to request the Secretariat to notify the Scientific Assessment Panel of the outcome of the preliminary assessment of the ODP to enable the Panel to review the assessment for each new substance in its annual report to the Parties and to recommend to the Parties when a more detailed assessment of the ODP of a listed new substance may be warranted.
