London Borough of Barking and Dagenham Air Quality Progress Report to April 2005 Introduction Barking and Dagenham is situated to the east of London, within the Greater London conurbation. It is largely residential with a sizeable industrial component. Industry is mixed with traditional manufacturing industries showing a reduction and newer transport and distribution industries increasing. The southern boundary of the borough is formed by the River Thames, with the London Boroughs of Newham and Redbridge to the west and north-west and the London Borough of Havering to the east. The borough is crossed from east to west by two main railway lines, and two major roads, the A12 and the A13. The latter is currently subject to a Design, Build, Finance and Operate (DBFO) contract between Transport for London (TfL) and Road Management Services (RMS). Both these roads carry a substantial amount of through traffic passing from Essex into London. There are a number of north- south routes, all of them borough roads. In 2002 the Council declared an Air Quality management Area covering residential properties on the A13. The area was declared because of possible exposure to the annual mean exposure levels for both NO2 and PM10 in excess of the air quality standards. There is no expectation of exposure to levels of other pollutants or other exposure criteria for NO2 and PM10. Air Quality Monitoring Monitoring within Barking and Dagenham is carried out for NO2, SO2 and PM10. Continuous monitoring of NO2 and SO2 has taken place at Rush Green Junior School in the north-west of the borough since the mid 1990s. Originally operated by Thames Power Services as part of planning agreement associated with the construction of the Barking Reach Power station it was handed over to the Council in 1999. PM10 is monitored at Scrattons Farm in the south of the borough. This site is approximately 200 metres south of the A13. It is also adjacent to the main construction site for the Channel Tunnel Rail Link and 300 metres north of the Barking Reach redevelopment area. The results of all continuous monitoring are shared with the London Air Quality Network operated by Kings College London on behalf of the London Boroughs. Diffusion tubes have been deployed at 6 sites in the Borough during 2002 and 2003, with a further four sites being added during 2003/4. The sites cover a range of locations, kerbside, roadside and background, across Barking and Dagenham. The locations of the monitoring stations across the borough are displayed graphically in the map below.

It can be seen that in 2003 the long periods of settled weather caused an increase in pollution levels for all pollutants, a feature that can be seen across the region. This is reflected in the results for PM10 monitoring as well. The results for the kerbside sites, particularly BD35 and BD39 show the greatest levels. The reduction for 2004 in levels at BD35 may in part be explained by the opening of the realigned A13 with improved traffic flows. During 2002 and particularly 2003 congestion at this point had been very high due to the disturbance caused by major road improvements. It is harder to explain the increase in levels at BD39. This tube is sited at the kerbside of a busy borough road adjacent to traffic lights on a railway bridge. This site is subject to high levels of localised congestion and above average levels of pollutant are to be expected. The site shows a gradual increase year on year with a reduction in 2002. During the months of July and August 2002 the road was closed to carry out major gas main repair works. This resulted in monthly means comparable with other background sites in the borough reducing the overall annual mean. The new locations (BG 42, 43, 44) opened during 2003/4 are kerbside sites of borough roads with open aspect and generally free flowing traffic. BG 42 came on stream in May 2003 and results may not be representative for the whole year. Initial results show that air quality levels at the kerb are at or just below objective levels for 2004. Sulphur Dioxide The initial review and assessment of air quality showed that sulphur dioxide is not a pollutant of concern. Monitoring results for station BG1 confirm this to be the case. PM10 Monitoring for PM10 takes place at one site in Barking and Dagenham. The site is nominally a background site, situated 200 metres south of the A13. It is likewise approximately 200 metres north of the main Channel Tunnel Rail Link construction site, which commenced operation during 2001. Results for the years 2001, 2002 and 2004 show that the levels of PM10 are well within the objective limits for both the annual mean and for days grater than 50 ug/m3 . The results for 2003 are elevated, both annual mean and exceedance levels. The annual mean is however within the objective. Pollutant levels across the region were raised during 2003 due to a series of unusual periods of high pressure causing exceptionally high levels of pollution. This is reflected in the results for site BG2. Levels for 2004 are consistent with previous years. Other Air Quality Data Complaints The number of complaints recorded as being agricultural odour, industrial odour and general air quality/pollution are detailed in table 4. There are considerable variations year on year for odour complaints that can be traced to specific incidents. The complaints categorised as air quality/pollution include domestic bonfire complaints and general enquiries.

Part A Processes There have been no new Part A processes commencing operations during the period 2001 – 2004. The time period has however seen the closure of four processes. The closed processes are: Blagden Packaging Chemical incineration Union Miniere Oxyde Zinc Oxide manufacture Exide Batteries Lead works Seabright Chemicals Fertiliser manufacture Part B Processes During the period 2001 – 2004 four new Part B processes opened within Barking and Dagenham. All the applications related to concrete crushing businesses with their operating bases within the borough.
