Audit Program
Testing Audit Program
Ohio EPA participates in U.S. EPA's stationary source testing audit program. Visit the U.S. EPA Emissions Measurement Center's Technical Support website to access information regarding which test methods have audits available and how to order audit samples. Audits provide a means for improved quality assurance of laboratory analyses and other aspects of source testing that may otherwise go unwitnessed and under-scrutinized.
Audits are required to be employed whenever samples are available.
