How is the STQ for Sabotage/Contamination chemicals of interest calculated in a mixture?
As provided in §27.204(c), a facility shall count toward the STQ the total quantity of all commercial grades of a sabotage/contamination chemical that it possesses unless specific minimum concentration is assigned in the Minimum Concentration column of Appendix A to 6 CFR 27, in which case the facility should count the total quantity of all commercial grades of the chemicals at the specified minimum concentration. DHS has added a definition of a “A Commercial Grade” (ACG) to a § 27.105. ACG refers to any quality or concentration of a chemical of interest offered for commercial sale that a facility uses, stores, manufactures or ships. Referenced Text: Additional information on the treatment of sabotage/contamination COI in a mixture under CFATS can be found in the preamble to Appendix A to CFATS at 72 FR 65406.
