This pilot … WebEPA Methods 325A and 325B. The Environmental Protection Agency has issued regulation 325A and 325B requiring all refineries to conduct benzene fence line monitoring. This regulation calls for Passive sampling onto sorbent tubes analyzed by TD-GC/MS as the standard air monitoring technology for the EPA’s proposed rule. WebUS EPA released Methods 325A and 325B especially designed for the refinery sector rules. These methods describe the use of passive absorbent tubes. In Europe the monitoring of benzene is also mandatory according to European Air Quality Directive - EN14662-3:2015.
