Benzene Fenceline Monitoring

EPA 325 Requirements

In September, 2015 the EPA finalized the "Refinery Risk, Techology Review and New Source Performance Standard" requiring refineries to implement a fenceline monitoring program for Benzene.  

EPA 325 includes two sub-parts:

  • EPA 325A: sampler Deployment and VOC Sample Collection
  • 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 poits around the refinery property line.  These samplers operate on a 2-week time period, with the devices being changed out and analyzed every 14 days.
