How is the STQ for Schedule 1 Chemicals calculated?
For more information on this topic, please reference the Final Rule, Appendix to Chemical Facility Anti-Terrorism Standards (http://www.dhs.gov/xlibrary/assets/chemsec_appendixafinalrule.pdf) on the DHS Critical Infrastructure: Chemical Security website. Referenced Text: The STQ for Schedule 1 chemicals is cumulative, or “CUM 100g,” meaning that all amounts of Schedule 1 chemicals at a facility count toward the cumulative STQ of 100 grams. Section 27.203(c) provides that “where a theft/diversion-Chemical Weapons (CW) chemical is designated by “CUM 100g,” a facility shall total the quantity of all such designated chemicals in its possession to determine whether the facility possesses theft/diversion-CW chemicals that meet or exceed the STQ of 100 grams.” This is an aggregate amount and not a per agent limit.
