Why doesn’t the AERA assess 100% of the air emissions?
The AERA does not assess all air emissions from a facility. Often, there is limited information to develop emission estimates or health benchmarks for all of the pollutants that could be emitted from a facility. Much of the information regarding toxicity or how a pollutant may move through the environment is unknown. Often, there are no emission estimates or health benchmarks for all of the pollutants that could be emitted from a facility.
