Noise
All machinery is fully enclosed in sound insulated buildings. In addition to the robust noise control, distance, trees, and terrain result in further noise reduction. Modelling by expert independent consultants has shown noise from the operation to be insignificant.

The basic rules for working with decibels
| Change in dB | Change in sound energy |
|---|---|
| 3 dB increase | sound energy is doubled |
| 3 dB decrease | sound energy is halved |
| 10 dB increase | sound energy is increased by a factor of 10 |
| 10 dB decrease | sound energy is decreased by a factor of 10 |
