When will DHS determine tier levels?
For more information on this topic, please reference page 6 of the Appendix to Chemical Facility Anti-Terrorism Standards; Final Rule http://www.dhs.gov/xlibrary/assets/chemsec_appendixafinalrule.pdf (PDF, 41 pages – 4.25 MB). Referenced Text: Only after the Department gathers additional information through the Top-Screen process will the Department make a determination as to whether a facility presents a high level of security risk and therefore must comply with the substantive requirements in part 27. Accordingly, the presence or amount of a particular chemical is not the sole factor in determining whether a facility presents a high level of security risk; it is not the only indicator of a facility’s coverage under part 27.
