London Borough of Croydon Air Quality Annual Status Summary Report for 2016

1 London Borough of Croydon Air Quality Annual Status Summary Report for 2016 Introduction This report provides a brief overview of air quality in the London Borough of Croydon during The EU sets limits for a number of known air pollutants, that member states must meet. The London Borough of Croydon is exceeding EU limits for the gas Nitrogen Dioxide (NO 2) in parts of the borough. The main areas of concern are air quality focus areas in the Borough where the EU annual mean limit values for NO2 (40 μgm -3 ) are exceeded and where there is high human exposure. The London Borough of Croydon is required by the Government and the Mayor of London to monitor air pollution in the borough, and take action to reduce it. The Government and the Mayor of London also have a range of responsibilities for taking action to reduce pollution. We are currently meeting the limits that are set by the EU for all other air pollutants, although we remain focused on Particulate Matter (PM 10 and PM 2.5). This is because these pollutants have detrimental impacts on health at any level. The main sources of pollution in the borough are road transport, diesel cars, TfL buses and HGVs, construction sites and domestic and commercial heating. NO2 We monitor NO2 across the borough through a combination of highly accurate continuous (or automatic) monitoring stations and indicative low-cost diffusion tubes. In 2016 overall levels of NO2 increased slightly at a number of background and roadside sites across the Borough. The Council s Park Lane monitoring site was installed on 02/11/2015 after having been relocated approximately 41m to the South of the George Street site. The 2016 results represent the first full year of NO 2 data. The Park Lane site in its first full operational year recorded an Annual Mean NO 2 concentration of 56 μgm -3 This is a notable increase in concentration when compared to the George street site 2015 annual mean of 45 μgm -3. PM10 We monitor PM10 at 1 Automatic monitoring station. In 2016, overall, levels of PM10 increased slightly. The Park Lane monitoring site was installed on 02/11/2015 after having been relocated approximately 41m to the South of the George Street site. The first full year of data from the Park Lane site showed an Annual Mean PM 10 concentration of 23.1 μgm -3 well below the target value of 40 μg m 3. This is a marginal increase in concentration when compared to the George street site 2015 annual mean of 21.6 μgm -3. PM2.5 We monitor PM 2.5 at 1 Automatic monitoring station. In 2016, overall, levels of PM 2.5 increased. The Council s Norbury Manor monitoring site was installed on 01/12/2014. The data represents the first two full years of monitoring. The results show that the PM 2.5 levels for 2015 and 2016 were below the target value of 25 μg m 3. The 2016 Annual Mean PM 2.5 concentration of μgm -3 shows an increase in concentration when compared to the 2015 annual mean of 10.05μgm 3. The increase in PM2.5 concentration should be approached with caution due to problems associated with the monitoring station analyser that resulted in poor data capture. Page 1

The numbers in each square are the annual mean NO 2 concentration for Summary Overall the monitoring results for the Borough show that NO 2 concentrations exceeded the UK annual mean objective at a number of locations (as it has done for each year since 2003). NO2 increased slightly at a number of background and roadside sites across the Borough. Due to the historically variable results associated these sites it is too early to say whether or not there are any true downward or upward trends. Page 3

The number in each blue square is the recorded annual mean PM 10 concentrations for The red square represents the Norbury Manor continuous PM 2.5 monitor. The target value for annual mean PM 2.5 is 25 g m -3. The number in each red square is the recorded annual mean PM 3.5 concentration for Summary The Park Lane PM 10 monitoring site was installed on 02/11/2015 while the Council s Norbury Manor PM 2.5 monitoring site was installed on 01/12/2014. These periods of analysis do not provide a long enough timeframe to establish any real trend. However the 2016 Annual Mean PM 2.5 concentration of μgm -3 is well below the target value of 25 μg m 3 and the 2016 Annual Mean PM 10 concentration of 23.1 μgm -3 well below the target value of 40 μg m 3.

6 Actions to Improve Air Quality The London Borough of Croydon s two main air quality achievements in 2016 were: Incorporating CLPs into planning conditions and the implementation of Construction Logistic Plans (CLPs) and servicing/delivery plans in the demolition and operational phases of developments to improve AQ and fleet efficiency. The continuation of the implementation of anti idling initiatives at schools, bus stands and other areas throughout the Borough. Co-ordinating the Clean air 4 schools project to reduce exposure to pollution in schools and reduce emissions from school buildings, increase walking and cycling, reduce idling vehicles and promote modal shift to walking, cycling and public transport. Funding and promoting airtext to continue the provision of air pollution alerts to vulnerable people and the expansion of the initiative into a London-wide scheme The London Borough of Croydon s two main priorities to reduce exposure to poor air quality for the year ahead are: There are unprecedented extensive construction works ongoing and proposed in Croydon over the next few years. To minimise pollution and congestion, Zonal Town Centre Construction Logistics has been developed which focuses on freight logistics. We will continue working towards developing this area of air quality improvement. This also links into our Low Emission Logistics Project working to improve air quality by reducing the number of delivery vehicles, working with local business and retailers to find out how their goods and services are delivered currently and in the future and what issues they expect to encounter. See the love clean air website ( Croydon is undergoing extensive development and we will continue to prioritise working towards improving air quality through the planning process by requiring, for example, registration to the Non Road Mobile Machinery (NRMM) scheme, CLPs, CEMPs and service delivery plans, AQ neutral/positive, the introduction of green infrastructure, Ultra Low NOx boilers, and the introduction of design features to new development to mitigate emissions in areas of higher pollution.
