US EPA Method 325 for fenceline air monitoring for benzene & other VOCs

Issued on 29 September 2015, US EPA Method 325 is required to comply with the new US federal regulation CFR 40. Monitoring of volatile organic compounds (VOCs) around the boundary of refineries requires 2-week passive sampling and TD–GC (or GC–MS) analysis.

Although benzene is the primary target compound of Method 325, the sampling and analysis methodology can also be used to determine other VOCs, including other hazardous airpollutants (HAPs) without further method development.

All petroleum refineries seeking compliance with US EPA regulations, together with federal, regional and independent test laboratories, have until 2018 to adhere to Method 325.
