This document is Ealing Council’s fifth Updating and Screening Assessment (USA). Results from monitoring by the Council are presented and sources of air pollution are identified. The USA determines those changes since the last assessment, which could lead to the risk of an air quality objective being exceeded. The USA 2012 report for the London Borough of Ealing identifies that: • For carbon monoxide, benzene, 1,3-butadiene, lead and sulphur dioxide there is not a significant risk of the objectives being exceeded in the Council’s area. • For nitrogen dioxide (NO2) and particles PM10 the Council has previously designated an AQMA across the whole of the Borough of Ealing. The findings from this report indicate that this AQMA should be maintained. Little has changed in terms of sources of emissions in Ealing since the fourth USA was undertaken in 2009. The results derived from this work will contribute to the next Progress Report and will add to subsequent Updating and Screening Assessments. They will also help inform planning applications for new developments. 1 of 67 London Borough of Ealing_USA_2012 December 2012 Contents 1 Introduction ..................................................................................................................... 5 1.1.
