摘要：	This report constitutes an air quality further assessment conducted by the Transport Research Laboratory (TRL Ltd) for Suffolk Coastal District Council (SCDC) as part of their Local Air Quality Management (LAQM) duties. The focus of the further assessment is an area to the south west of Felixstowe where an Air Quality Management Area (AQMA) was declared for annual nitrogen dioxide (NO2) concentrations at the Dooley Inn public house on Ferry Lane in 2009. Annual mean concentrations of NO2 and particulate matter with an aerodynamic diameter of less than 10 microns (PM10) and short-term (hourly) concentrations of sulphur dioxide (SO2) have been modelled using the ADMS-Roads dispersion model for the base year of 2008. The modelling assessment has confirmed the findings of the 2008 detailed assessment, with exceedance of the NO2 annual average objective concentration predicted at the Dooley Inn public house on Ferry Lane. There are no predicted exceedances of the PM10 or SO2 objectives in the base year of 2008. Based on the modelled results, the recommendation is that the existing AQMA boundary for NO2 is appropriate and should not be revoked. A source apportionment exercise has been carried out to determine the contribution of sources to the total modelled concentration of oxides of nitrogen (NOX) at the Dooley Inn public house on Ferry Lane. Container handling activities in the port and heavy duty vehicles (HDVs) on roads external to the port were found to make the greatest contribution to NOX concentrations at this receptor.
