Emission Sources

9.3.1 Industrial

Defra guidance lists the significance of industrial sources, by process type, as a percentage of the total Part A emissions in 2000 and Part B process types that are considered likely to emit significant emissions.

Appendix B details Part A and Part B industrial sources identified in the Council’s Stage 1

report. From processes were

a review identified

of this information, the SEPG as potentially significant sources

and Coldthrop of SO2.





During the first round of Review and Assessment, industrial sources were determined not to release significant emissions of SO2 and would not result in an exceedence of the AQOs. No changes to the process emissions have been identified and it is therefore considered that the Part A processes do not require further assessment.

9.3.2 Boilers No boiler plants >5MW have been identified within West Berkshire.

9.3.3 Domestic

The continued use of coal and smokeless fuel within areas of the UK has the potential to impact on local emissions of SO2. These impacts tend to be concentrated in small areas, which are generally less than 1 km2.

Defra guidance has identified the risk of exceeding the AQOs in an area to be significant where the density of ‘coal’ burning houses exceeds 100 properties per 500 m2 area.

The Council’s Stage 1 report did not identify any areas of potentially significant domestic sources, based on the 1998 guidance criteria of a 1 km2 grid square with emissions greater than 40 tonnes/year, or 300 houses in a 1 km x 1 km grid square.

A conservative assessment, based on this criteria, would indicate that 300 houses within a 1 km x 1 km grid square would equate to 75 houses in a 500 m2 area (assuming an equal distribution). Based on this calculation it is unlikely that domestic emissions would exceed the criteria of 100 properties in West Berkshire.

9.3.4 Other No other sources, such as shipping, have been identified with the West Berkshire District.
