Blue Town & Queenborough Inventory of Air Emissions AGGX3790131/BV/AQ/BW/2686 March 2011 Environmental Services SWALE BOROUGH COUNCIL BLUE TOWN AND QUEENBOROUGH – INVENTORY OF AIR EMISSIONS AGGX3790131/BV/AQ/BW/2686 This page is left blank intentionally SWALE BOROUGH COUNCIL BLUE TOWN AND QUEENBOROUGH – INVENTORY OF AIR EMISSISONS Executive Summary This report details an assessment into the levels of NOx, PM10 and SO2 emission from a variety of different sources in the Blue Town and Queenborough areas within the administrative area of Swale Borough Council. As these areas have been identified as a cause for concern in terms of air pollution, the Council has considered it necessary to commission a local pollutant Emissions Inventory, to serve the following purposes: • To get accurate estimates for pollutant emissions • To inform policy in order to develop appropriate policies/strategies for emission reductions • To feed into air quality dispersion modelling to assess air quality impacts The methodology for each emission sector of the Emissions Inventory was chosen with consideration of the latest available guidance and emission factors. Emissions were calculated using local information obtained from a variety of sources combined with default parameters and/or recommended values found in literature, based on previous studies. From the results, it can be concluded that shipping contributes the highest percentage of emissions for all three pollutants estimated within the study area. Over 93% of the SO2 emissions are attributed to marine vessels. They also contribute over 66% of overall NOx emissions, and 75% of PM10 emissions. Part A Processes were also found to contribute a large proportion of NOx and PM10 emissions. i SWALE BOROUGH COUNCIL BLUE TOWN AND QUEENBOROUGH – INVENTORY OF AIR EMISSISONS TABLE OF CONTENTS

Swale Borough Council (SBC) to develop an Emissions Inventory of air pollutants for the Blue Town (suburb of Sheerness) and Queenborough areas. As emission sources in this area are complex and varied, including the Port of Sheerness, and several industrial sites, SBC decided to prepare a detailed inventory of air emissions for the following purposes:
