45+ terminals

Marketing Storage Terminals

Trace monitors more than 45 storage terminals nationwide, continuously measuring emissions from Vapor Combustor Units (VCUs) and Vapor Recovery Units (VRUs) at marine and truck loading racks.

Parameters monitored

  • VOCs
  • CO
  • O₂
  • + more as required

Every system is configured plant by plant — if your permit calls for a source or parameter that isn't listed, we monitor that too.

What Trace does for marketing storage terminals

  • Fully compliant continuous stack monitoring and reporting for VOCs, CO, and O₂.
  • Explosion-proof (Class I, Div. II) and weather-proof (NEMA 4X) construction.
  • Handshakes with terminal control systems to auto-shut-off loading/unloading as needed.
