The Plume Plot for the Chineham Incinerator
The map shows the (predicted) current state of pollution from the incinerator at Whitmarsh Lane.
The red line shows wind direction. Green rings show distance (km). Colours show concentration of oxides of nitrogen at ground level.
The Chineham Plume Plotter shows a prediction of the current amount of air pollution (at ground level) caused by emissions from the incinerator at Chineham.
Plume Plotter predicts this fallout using AERMOD, which is one of the most widely used modelling systems for air pollution. It uses the latest local weather conditions and upper air data, which are obtained in real time. Plume Plotter does not use real-time information about the incinerator’s emissions. Instead, it assumes that the incinerator is operating continuously (8760 hours per year) and emitting pollutants at a constant rate.
The emission rates assumed are either:
- the long-term planned emission rates that were specified by the incinerator developers in their planning application;
- the average actual emission rates for a recent year, as measured and reported by the incinerator operators.
