Local air quality management further assessment at Olney

This Air Quality Further Assessment has been produced by Transport Research Laboratory Ltd (TRL) for Milton Keynes Council as part of their Local Air Quality Management (LAQM) duties. The Further Assessment focuses on the market town of Olney, Buckinghamshire, where an Air Quality Management Area (AQMA) was declared for annual nitrogen dioxide (NO2) concentrations in 2008. Annual mean concentrations of NO2 were modelled using the ADMS-Roads dispersion model for the base year of 2007 and the future years of 2010 and 2016. The Further Assessment determined that emissions from heavy goods vehicles (HGVs) contributed to at least 50 of the NO2 concentrations at receptors along Bridge Street and High Street South. The modelling also confirmed the findings in the Detailed Assessment that exceedences of the annual mean objective in 2007 were predicted at relevant receptors along both roads. These exceedences were within the existing AQMA boundary and it was recommended that the boundary should not be amended. Future reductions in NOX road traffic emissions meant that the objective should be met at all receptors by 2016. The report provides recommendations on measures that Milton Keynes Council may consider in their Air Quality Action Plan for introduction by the year 2010. Several measures were modelled that focused on reducing HGV emissions, including a complete HGV ban or restricting HGV access at certain types of day to Olney. A complete ban of all HGVs was shown to result in an average reduction of 10 in annual mean concentrations in 2010 compared to the baseline. (A)
