Dust emissions from the Ashton Open Cut are monitored via a real-time environmental monitoring system with a total of 7 stations strategically located around the site. Mining operations are modified based on the monitoring results and observations to ensure compliance with licence conditions.

Ashton Coal has a nil discharge Environment Protection Licence and as a result there are no discharges of contaminated or saline water. All contaminated or saline water is captured in the Site Water Management System and is used for dust suppression and coal processing. Water quality is measured at 14 locations off-site on the streams in the area.

Noise emissions are controlled by the installation of sound reduction equipment on plant and equipment, and by the establishment of environmental noise bunds at strategic locations around the site. Attended compliance monitoring is conducted 3 monthly within Camberwell Village.

Blasting activities are monitored at three locations, as detailed in Ashton Coal's Blast / Vibration Management Plan. Procedures are in place to ensure that ground vibration and air overpressure are within licence conditions. A vibration prediction tool is also ustilised to ensure all blasts are designed to produce vibration below licence conditions.
