Ecology proposes to update TransAlta’s permit, called a BART (best available retrofit technology) order.
The proposed revision requires TransAlta to:
- Install and operate a computerized combustion control system to lower emissions of nitrogen oxides and ammonia.
- Remove requirements to test coal before using it because testing occurs where air pollution comes out.
- Limit monitoring of ammonia.

TransAlta is a coal-fired power plant in Centralia. In 2011, the Legislature required TransAlta to shut down its coal-fired boilers in two phases. Ecology regulates air pollution from industrial facilities, including power plants. We monitor TransAlta's emissions.
