Air Permits Broken Bag Sensors
Oldies....and not so goodiesPlume opacity emission standards and requirements have played a key role in enforcement of federal, state, and local air pollution regulations. Failure to take these regulations seriously can be costly, as violations of opacity limits for air permits can result in up to $25,000 per source per day!
For decades, the most common method used to monitor opacity levels has been the EPA method 9 and 22 visual observation tests. Consistent economical compliance relies on a better understanding of these tests, how they related to legacy air permits in the past ,and how they will relate going forward.
What are Method 9 and Method 22?
