OAQPS Precursor Gas Program Goals

• Develop in-house expertise and knowledge for the
  setup and operation of low-level CO, SO2 and NOy
  monitors
• Operate monitors in a lab and field setting to
  expand this knowledge
• Evaluate monitor precision, bias and verify
  vendor specifications
• Develop technical guidance, standard operating
  procedures (SOPs) and method summaries
• Transfer this technology to State/Local/Tribal
  agencies
