Air Quality Management
The management of air quality from Alcoa’s Wagerup refinery receives close community and government scrutiny and we are committed to ongoing improvement in this area. In recent years Alcoa has worked with scientists from the DoE, Chemistry Centre of Western Australia (CCWA), the CSIRO and community representatives to better understand and manage air quality at Wagerup. This work has contributed to a number of successful emission reductions projects which have resulted in significant improvements in key areas. Outcomes of detailed monitoring and modelling work conducted in 2005 show the air quality around the Wagerup refinery is typical of a rural Australian environment in terms of the nature and quantity of chemicals found. It also found the refinery contributes only a small amount of chemical compounds to local air.

Noise monitoring @ Wagerup
In addition to continuous noise monitoring, source monitoring is undertaken at specific points around the refinery.

In-stack monitoring @ Wagerup
External consultants ECS perform in-stack monitoring on the calciners at Wagerup refinery.
