Are the people involved with making public health decisions aware of the patchy nature of the distribution of odours?
The site team and regulators are aware of this and take this into account when investigating concerns. This is why it is important to telephone the Environment Agency hotline (0800 80 70 60) at the time the smell is affecting you/your activities in order to give a better understanding of how processes on site/wind direction/weather conditions are affecting the distribution of odours.
