Worcester City CouncilExecutive SummaryThis report presents the findings of Worcester City Council’s Updating and ScreeningAssessment (USA) of air quality within the city. The USA evaluates new and changedsources to identify those that may give rise to a risk of an exceedence of an airquality objective. Results from monitoring within the city are also presented andevaluated in relation to the objectives; the likelihood of an exceedence at relevantlocations is discussed, as is the requirement to proceed to a Detailed Assessment.Previous Review and Assessments have concluded that concentrations of carbonmonoxide, benzene, 1,3-butadiene, lead, sulphur dioxide and PM 10 are compliantwith the relevant objectives. Air Quality Management Areas (AQMAs) have howeverbeen declared at three locations for exceedences of the annual mean nitrogendioxide objective.Monitoring data for 2011 show that there is the risk of exceedences of the annualmean nitrogen dioxide objective at two locations representative of relevant exposureoutside of the existing AQMAs; these locations both lie within the City Wide AQMAwhich is currently under consultation.The USA has not identified any significant changes in emissions sources within theWorcester City Council area.LAQM USA 2012ii
