The Hazardous Organic NESHAP (HON) Rule mandates stringent fenceline monitoring requirements for hazardous air pollutants (HAPs). Traditionally, passive methods such as EPA Methods 325A/B and 327 have been used to detect emissions. However, recent advancements in real-time monitoring technology provide facilities with a superior alternative that not only meets compliance but also offers significant operational advantages. 

Picarro’s comprehensive Fenceline Monitoring Solution integrates advanced hardware, software, and data analytics to provide industrial sites with automated fenceline monitoring, leak detection, and compliance reporting along with EPA alternative approval pathways.
