Plume opacity emission standards have been essential for decades in the enforcement of air pollution regulations at the federal, state and local level. Failure to adhere to these regulations is very costly, as violations of opacity limits for air permits result in fines as much as $25,000 per source, per day. The most common methods to monitor opacity levels is the EPA Method 9 and EPA Method 22.
