Stack Tests and Relative Accuracy Test Audits (RATA)

Licensed facilities may be required to periodically test emissions (also known as Stack Testing or Emissions Testing) from their equipment. Additionally, facilities with continuous emissions monitoring equipment must perform Relative Accuracy Test Audits (RATA) to demonstrate the emissions monitoring equipment is operating correctly. Below is information on submitting the required test protocols and final reports to the Department.
