Aberdeen City Council 2015 Updating and Screening Assessment for Aberdeen City Council In fulfillment of Part IV of the Environment Act 1995 Local Air Quality Management June 2015 LAQM USA 2015 1 Aberdeen City Council Local Authority Nick Glover Officer Department Environmental Health & Trading Standards Aberdeen City Council Marischal College Business Hub 15 Address Broad Street Aberdeen AB10 1AB Telephone 01224 523 737 e-mail [email protected] Report Reference 001 number Date June 2015 LAQM USA 2015 2 Aberdeen City Council Executive Summary This Updating and Screening Assessment has been undertaken to fulfil Aberdeen City Council’s duty to annually review and assess air quality. The Report provides the latest monitoring results and discusses the implications for air quality management in Aberdeen. In writing the Report, the Council has regard to the Government’s published guidance LAQM.TG(09). In 2014 the annual mean nitrogen dioxide level (NO2) continued to exceed the national air quality objective across the City Centre Air Quality Management Area (AQMA). Pockets of exceedances were also recorded within the Wellington Road and Anderson Drive/Haudagain Roundabout/Auchmill Road AQMAs indicating the 3 AQMAs remain valid. The annual mean NO2 at the Union Street automatic monitoring site has been decreasing since 2012. The NO2 annual objective at the Market Street continuous monitoring site has also continued to fall since 2012 and this year just met the objective. There were no exceedances of the NO2 1 hour objective at the continuous monitoring sites. Concentrations >60ugm-3 were not recorded at any of the diffusion tube locations across the city suggesting the 1-hour objective was met. The annual mean PM10 objective was exceeded at Wellington Road and Market Street. The annual mean PM10 objective continued to be marginally exceeded at the King Street continuous monitoring station. Concentrations from the BAM monitor at this location may be elevated during prolonged periods of heavy rain and sea mist. Further assessment is still not proposed at this time, however concentrations will continue to be monitored and reviewed to determine if further action is necessary. The Market Street continuous monitor was the only site that exceeded the 24 hour mean (22 days >50ugm-3). There appears to be a slight decrease in PM10 concentrations in 2014 compared to 2013. There were no exceedances of the objectives at any other location outwith the AQMAs. The 2014 monitoring data has not identified the need to proceed to a Detailed Assessment for any pollutant.
