## Abstract

The Bureau of Industry and Security (BIS) is publishing this final rule to amend the Export Administration Regulations (EAR) by revising the Commerce Control List (CCL) entry that describes controls on certain toxic gas monitoring systems to conform with the Australia Group (AG) "Control List of Dual-Use Chemical Manufacturing Facilities and Equipment and Related Technology." Specifically, this final rule removes a technical note that contained an overly broad description of the types of toxic gas monitoring systems and detectors subject to chemical/biological (CB) controls under the EAR. The note covered a number of toxic gas monitoring systems and detectors not included on the AG control list. By removing the technical note, this final rule eliminates the CB license requirement for these toxic gas monitoring systems and detectors. Toxic gas monitoring systems and detectors that are included on the AG control list continue to require a license, for CB reasons, to certain destinations.
