Department of Homeland Security Chemicals of Interest List (COI)
On November 2, 2007, the Department of Homeland Security (DHS) released a final list of 300 chemicals that, if a facility possesses in certain quantities, triggers a requirement for an assessment, known as Top Screen, to be completed. DHS will use the Top Screens to determine whether the facility should be regulated as a high-level risk. http://www.ecfr.gov/cgi-bin/text- idx?c=ecfr&SID=65889784a49874d0c06df97bf085acaa&rgn=div5&view=text&node=6:1.0.1.1. 10&idno=6
To determine the type and quantity of chemicals that will be subject to the preliminary screening process, DHS examined the following three security issues: 1. Release – quantities of toxic, flammable, or explosive chemicals that have the potential to create significant adverse consequences for human life or health if intentionally released or detonated; 2. Theft and diversion – chemicals that have the potential, if stolen or diverted, to be used or converted into weapons; and 3. Sabotage and contamination – chemicals that, if mixed with other readily available materials, have the potential to create significant adverse consequences for human life or health.
The department identified these chemicals in the specific amounts for preliminary screening based on their potential to create significant human life or health consequences.
College and University Laboratories All facilities that possess chemicals listed in Appendix A in quantities at or above the STQs will have to complete and submit a Top-Screen. The Appendix A requirements for Top-Screen may require colleges and universities to comply
