Benzene Fenceline Monitoring

EPA Method 325 Requirements

In September, 2015 the EPA finalized the "Petroleum Refinery Sector Risk and Technology Review and New Source Performance Standards" ruling requiring refineries to implement a fenceline monitoring program for Benzene following EPA Method 325, “Volatile Organic Compounds from Fugitive and Area Sources” by the end of January, 2018.  EPA Method 325 includes two sub-parts, EPA 325A: Sampler Deployment and VOC Sample Collection  and EPA 325B:  Sampler Preparation and Analysis.  These complimentary methods cover the design, deployment, preparation, and analysis of a series of passive diffusion sampling devices located at specified points around the refinery property line.
