The JP3 VeraCal®️ is now EPA-approved (ALT-157) and backed by an independent assessment from Verus Environmental LLC and Michael Stovern, Ph.D.
VeraCal is setting a new standard for continuous flare gas monitoring under Subpart W.
The VeraCal optical calorimeter meets or exceeds EPA’s performance, accuracy, and data integrity requirements for continuous vent gas NHV and composition monitoring. Based on its EPA-approved ALT-157, a robust Method 301 validation conducted in this document (LINK), and technical alignment with Subpart W provisions, VeraCal appears to be broadly applicable for Subpart W flare Tier 1 and Tier 2 compliance applications.
