2015 Updating and Screening Assessment for Dundee City Council In fulfillment of Part IV of the Environment Act 1995 Local Air Quality Management June 2015 Dundee City Council Iris Whyte Local Authority R Brooks Officer J Baird Department Environment Department Address 3 City Square, Dundee, DD1 3BA Telephone 01382 436235 e-mail [email protected] Report Reference DCC_USA_2015 number Date June 2015 Updating and Screening Assessment 2015 Dundee City Council Executive Summary This report is the 2015 Updating and Screening Assessment (USA) of air quality for Dundee City Council. It fulfils the requirements of the Local Air Quality Management (LAQM) process as set out in Part IV of the Environment Act 1995 and the National Air Quality Strategy 2007. The report has been completed in accordance with statutory Technical Guidance (LAQM.TG(09)) produced by DEFRA and the Devolved Administrations. The objective of an Updating and Screening Assessment is to identify any matters that have changed which may lead to a risk of an air quality objective being exceeded, and whether there is sufficient risk of an exceedence to justify a Detailed Assessment. Regulations prescribe health based air quality objectives for seven pollutants. The whole of Dundee has been declared an Air Quality Management Area (AQMA) for 3 3 nitrogen dioxide (NO2) (40µg/m ) and particulate matter (PM10) (18µg/m ) annual mean 3 objectives and the one hour mean objective for NO2 (200µg/m ). Having considered and assessed each emission source (as necessary), it is concluded that the air quality objectives for benzene, 1, 3-butadiene, carbon monoxide, lead, and sulphur dioxide (SO2) will be met. The 2014 monitoring data confirm the continuing need for the AQMA and the subsequent Air Quality Action Plan (AQAP). Annual mean concentrations of NO2 and PM10 remain above the objective or are ‘borderline’ in several areas of the city. No exceedences of the hourly mean objective for NO2 were recorded in 2014. No exceedences of any of the SO2 objectives were recorded in 2014. Exceedences of the Scottish 24 hour mean PM10 objective were recorded at two locations using indicative monitors. The need for a Detailed Assessment for this pollutant objective will be kept under review. The assessment of the various pollutant emission sources, including road traffic, industry, solid fuel combustion etc., has identified several roads, a fugitive emission source and biomass combined combustion sources which require further investigation. The Dundee City Council USA 2015 concludes that no assessments of monitoring data or emission sources justify the need to proceed to a Detailed Assessment for any pollutant. Proposed actions arising from the USA 2015 are listed in Section 9.3.
