The information from these groups and others will be assessed as the committee's work continues.
Further Work by the Committee
As the study continues, the committee will continue to assess existing and additional detection and identification taggant approaches. It will also examine existing and proposed means for desensitizing explosive materials and assess possible controls on precursor chemicals. The committee will also continue to solicit input from the scientific community and affected stakeholders on the issues raised in the committee's charge and on information sources the committee should consider during the course of the study. The results of the committee's work will be published in a final report to be completed by February 1998.
