Tilting at windmills: A Health Impact Assessment of the Lewis Wind farm proposals

1. Tilting at windmills: A Health Impact Assessment of the Lewis Wind farm proposals Julie Yates – Public Health Nurse Consultant Lucy Macleod – Public Health Specialist

7. Socio-economic & demographic issues • High levels deprivation • Low levels economic development • Poor health indicators (men) • Declining employment opportunities • Out migration • Aging population • Culture

9. The Lewis Proposals • Lewis Wind Power • 234 turbines • 140m / 100m to hub • Eisgein Bhein Mhor • 133 turbines • 120m / 80m to hub • Pairc • ? 80+ turbines

10. LWP 167km roads 9 electrical substations Control building 9 Monitoring masts 210 pylons (80m) 5 Quarries 8 temporary compounds 4 concrete batching plants 4,000,000 cubic metres of rock Bhein Mhor 77km roads 1 substation 1 Control building 5 Monitoring masts ? Pylons 22 Quarries 10 temporary compounds 10 batching plants 150,000 additional two-way road movements Vehicles over 50m in length What would this involve?

13. Limitations of Review • Time • No studies found on developments of similar scale in terms of: • Turbine size • Turbine numbers • Proximity to houses • Proximity to other similar sized developments

14. Physical Effects Mental Health Impacts Social/WellbeingEffects

15. Physical Impacts • Noise • Shadow Flicker • may be a problem to some individuals • can be avoided by careful siting Advised to check LWP modelling and request similar from Beinn Mhor

16. Physical Impacts • Power cables • Many assertions of health effects • Most unresearched or unsubstantiated • Some correlation with childhood leukaemia • Research continuing on this and Melatonin • No irrefutable proof either way Advise that Comhairle may wish to take more expert advice. Cables and pylons should be as far from houses as possible. Not less than 100m.

17. Physical Effects • Safety • Accidents • Road safety (construction and operation) • Blade breakage, icing, fires Advised that more information is required on operational safety. Plans should be checked through with Police/road safety, fire and NHS. May require a condition relating to operation sub zero.

20. Mental Health Impacts • GP Studies – sleep disturbance, stress,depression • Property value – RICS survey • Construction and transportation phase • Quality of life Advised consultation with affected communities. Possibility of financial package. Consult young people.

22. Social / Wellbeing Effects • Housing and Public Health • Potentially significant numbers of transient workers • Potential impact on homelessness services • Integration with local community • Alcohol, drugs and sexual health Advised involvement of ADSAT, Police and local communities in housing decisions.

23. Social/Wellbeing Effects • Repopulation and Depopulation • Economic Impacts on individual and community health and wellbeing • Inaccuracy in LWP assessment Advised: • Exit strategy to counter post-contract decline. • Need for workplace health improvement and occupational health. • Monitor and manage impacts on other sectors • Look at integration issues • Consult on plans for handling community benefit

24. Conclusions Direct Health Impacts • No direct benefits to health from the proposals • Negative physical health impacts should be controllable through planning conditions, but uncertainty over effect of high voltage power cables

25. Conclusions Indirect • A net increase in sustainable long term employment is possible but not certain • The developments could lead to repopulation or depopulation • The main potential gain is from community benefit if it can be handled in an inclusive way to promote community regeneration • Housing is a major issue

26. Final Assessment These developments have the potential to be of benefit to community health and wellbeing, they also have the potential to cause significant negative health impacts. The community and broader public health impacts will require ongoing assessment and management

27. Final Recommendation That should one or both developments go ahead, the mechanisms are put in place for an ongoing Health Impact Assessment: • To provide early warning of problems which can be managed, reduced or avoided • To provide information which could be used in future applications in the Western Isles • To provide information which could be used elsewhere either in specific relation to wind farms or to provide information on the impacts of industrial developments in rural areas • To develop a marketable expertise.

28. What happened next….. • Stornoway Gazette • “Wind farms fan the flames of racist unrest in the isles….” Observer, May 2005 • Commission for Racial Equality • Internal review & investigation

29. What did we learn? • Health Impact Assessment methodology provided a useful, systematic and rigorous framework for comprehensive analysis of complex issues • We were naïve ! • Recognise the dangers of inexperience….. • Do not underestimate the interest & role of the media • Consider the benefits of a fully participatory assessment process • Remember - in small communities debates rapidly become personalised. • Urge caution. Start small & uncontroversial, get partners used to the methodology & its benefits when there is little at stake…... and make more of an impact later!
