Southdowns was commissioned by AMS Limited to undertake detailed air dispersion modelling for the assessment of air quality impacts associated with proposals for Disaster Recovery Scheme at Queen Alexandra Hospital in Cosham.
A detailed modelling assessment was undertaken for the operation of a new Disaster Recovery Scheme to provide a backup supply of steam in the event of critical failure. ADMS-Roads software was employed.
The assessment incorporated embedded mitigation within the model by strategically locating the boilers and increasing flue stack heights to minimise impacts on local air quality.
The assessment considered the adjacent Portsdown Hill Nature Reserve Site of Special Scientific Interest (SSSI) and demonstrated that NO2 concentrations from the new Disaster Recovery Scheme were permissible.
The results of this assessment showed that air quality did not present a constraint to the operation of the Disaster Recovery Scheme.
