1. 1 Origin Renewable Energy - Energy from Waste (EfW) Plant at Magnetic Park, Desborough Appraisal of Air Quality Impacts Associated with Stack Emissions Chris Haigh – Technical Director

2. 2 Air Quality Regulations 2010 - Definitions “…outdoor air in the troposphere, excluding workplaces where members of the public do not have regular access.” “Compliance with the limit values directed at the protection of human health does not need to be assessed at the following locations: any location situated within areas where members of the public do not have access and there is no fixed habitation; on factory premises or at industrial locations to which all relevant provisions concerning health and safety at work apply; on the carriageway of roads and on the central reservation of roads except where there is normally pedestrian access to the central reservation.”

4. 4 Impacts of Polluting Emissions

5. 5 What information is needed for the modelling?  Stack Source Information  source type (point, line, area)  pollutant emission rate  Receptor Information  residential areas  shops/offices  recreational facilities  ecologically-designated sites  Local Topography  OS maps, aerial photographs and site visit  Local Meteorological Information

6. 6 Weather Data Five years of data from RAF Wittering Other Local Stations Monks Wood Moulton Park Church Lawton Market Bosworth Sutton Bonnington

7. 7 Predicted Impacts - Nitrogen Dioxide (NO 2 )

8. 8 Predicted Impacts – Energy from Waste (EfW) NO 2 concentration 0.4 – 0.6  g/m 3 NO 2 concentration 0.6-0.8  g/m 3 Stack Location NO 2 concentration 0.8 -1.0  g/m 3 NO 2 concentration 1.0-1.2  g/m 3

9. 9 Ultra Fine Particulate Matter – PM 2.5  Particulate matter equal to or below 2.5 micrometers in aerodynamic diameter – 1/30th the width of a human hair  Manmade PM 2.5 mainly from combustion sources  Health studies in USA have shown an association between ultra fine particulates and increased hospital admissions and even premature death  COMEAP indicates that 1 µg/m 3 decrease in PM 2.5 over a lifetime exposure of 80 years will gain an extra 1.5-3.5 days per individual  PM 2.5 annual mean limit value/standard of 25 µg/m 3 in the Air Quality Standards Regulations 2010 and Directive 2008/50/EC of the European Parliament and of the Council of 21 May 2008 on ambient air quality and cleaner air for Europe  PM 2.5 annual mean value/standard of 20 µg/m 3 by 2020 (to be reviewed by the European Commission in 2013)

10. 10 Sources of Ultra fine Particulate Matter in the UK Total emission - 95,500 tonnes – 2005 - 83,210 tonnes – 2010 Combustion of all wastes - 500 tonnes – 2005 (including small scale burning and vehicle fires)

11. 11 Ultrafine Particulate Monitoring

12. 12 Summary Nitrogen Dioxide – NO 2  Effects from the EfW on air quality in the area are considered to be negligible.  Magnetic Park EfW will contribute <3% of the air quality standard Ultra fine Particulate Matter – PM 2.5  Not possible to discern a level where there are no adverse effects  Annual mean concentration limit values and standards set an EU and UK level  Magnetic Park EfW will only contribute <0.1% of current limit value/standard
