(ASR) - 2018 Air Quality Annual Status Report

South Bucks District Council i Executive Summary: Air Quality in Our Area Air Quality in South Bucks District Council Air pollution is associated with a number of adverse health impacts. It is recognised as a contributing factor in the onset of heart disease and cancer. Additionally, air pollution particularly affects the most vulnerable in society: children and older people, and those with heart and lung conditions. There is also often a strong correlation with equalities issues, because areas with poor air quality are also often the less affluent areas1,2 .

The annual health cost to society of the impacts of particulate matter alone in the UK is estimated to be around £16 billion3 . Owing to the largely rural nature of the district, the primary sources of pollution are transport related sources including the motorways (M25, M40, and M4) which pass through the district. An AQMA was declared around the motorway corridors in 2004. The detailed assessment at the time identified the following properties as sensitive receptors:  An area north of the M4 in the Oak Stubbs Lane area North of the M4  To the south of the M4 where the B3026 crosses the motorway.  Cherry Orchard Farm to the East of the M25  At Gerrards Cross where the A40 crosses the M25. Modelled concentrations were modelled close to the objectives at sensitive receptors in 2004.

 Sutton End Cottage to the North of the M4  Victoria Crescent to the west of the M25 1 Environmental equity, air quality, socioeconomic status and respiratory health, 2010 2 Air quality and social deprivation in the UK: an environmental inequalities analysis, 2006 3 Defra. Abatement cost guidance for valuing changes in air quality, May 2013

South Bucks District Council ii  Wooburn Green Lane to the north of the M40  Coldharbour Farm cottage to the west of the M25. Where possible, additional monitoring locations will be set up in 2018 to monitor exposure of these sensitive receptors to pollution from the motorways. The further assessment carried out for the motorway AQMAs revealed that on the M40 approximately 61-64% of the total emissions are related to the HGVs. On the M25 these figures rise to 74-76%, while on the M4 the figures are 65-70%. The remaining emissions are attributable to the LGVs, which although contribute larger numbers in terms of vehicle numbers, contribute less in terms of overall emissions. Therefore, an Action Plan that focuses on reducing the number of HDVs travelling through the District would probably be a more practical means by which to reduce overall emissions. For example, a 1% reduction in HDV movements on the M25 is likely to bring about a reduction approaching 5% in terms of total NOX road traffic emissions. Whilst South Bucks has very little control on the traffic travelling through the district on the motorway it can influence the fleet of HGVs which travel on local roads and ultimately move on to the motorway.

Buckinghamshire County Council (BCC) commissioned a consultancy to examine existing transport and traffic conditions in and around Iver Parish and the impact of future major infrastructure project developments. These include:  Crossrail (Elizabeth Line)  M4 Smart Motorway  Western Rail Link to Heathrow (WRLtH)  HS2  Third Runway at Heathrow Proposed local Developments include:  CEMEX North Park Extraction

South Bucks District Council iii  Relocation of Hillingdon Outdoor Activity Centre (HOAC)  Pinewood Studios Development Framework (PSDF) As South Bucks is now a shared service with Chiltern District Council, there will be opportunities to work together, and also with Bucks Air Quality Management Group on county wide initiatives to address large infrastructure developments in the south- east. The Bucks Air Quality Management Group consisting of Aylesbury Vale, Chiltern, Milton Keynes, South Bucks and Wycombe authorities has been reinvigorated in order to look at area wide air quality initiatives and to build a closer working relationship with departments within Bucks County Council (BCC) such as Transport and Public Health Departments and outside agencies such as The Environment Agency, Public Health England and Highways England.

Actions to Improve Air Quality Many of the actions contained with the Action Plan have now been completed or are ongoing. The Air Quality Action is currently being reviewed and further actions will be considered alongside identifying potential funding opportunities. Cycling initiatives and car share schemes have been at the heart of the district’s Air Quality Action Plan, and will continue to be addressed so that residents can make sustainable transport choices. The County Council has developed route maps for a number of towns in Buckinghamshire including Beaconsfield and Gerrards Cross. These maps show bus, cycle and walking routes within the towns listed. They contain a frequency summary of the bus routes and where they go, as well as a useful index showing direct bus, rail and tube services available to nearby towns and villages. Beaconsfield Shared-use Cycleway, Grenfell Road to Ledborough Lane – The project is to extend the existing Beaconsfield Cycle Network with the upgrade of the existing footpath to form a new section of off-road shared use path for cyclists and pedestrians, between Grenfell Road and Ledborough Lane.

South Bucks District Council iv The Beaconsfield Cycleway Network aims to provide a safe cycle route for leisure use, commuting and travelling to school, potentially benefitting a vast proportion of the local population. It is hoped that by encouraging more people to use the route, there will be a subsequent decrease in car use locally, causing positive benefits to congestion levels and the environment. The Beaconsfield Cycle Network has been keenly promoted by Beaconsfield Cycle Paths Action Group, (also providers of the cycle stands), and has been working with BCC to encourage use of the Cycleway Network with the local schools. South Bucks District Council promoted Clean Air Day 2017 on social media by tweeting throughout the day. Council staff also pledged to take more sustainable choices when travelling to work. Clean Air Day toolkits were emailed to all schools in Iver and Council Staff handed out leaflets at the entrance to Iver Village Junior School at home time. The school had held a Clean Air Day themed assembly that morning and the children were keen to share what they had learnt.

South Bucks District Council v Source: Slough Observer, Friday June 30th 2017 page 24. The Strategic Environment team have been working with Planning Policy to ensure that full consideration has been given to air quality within the local plan. The council has also been developing Local Air Quality guidance for developers which requires developers to assess the impact the development on Air Quality using the following staged process:  Using the ‘Screening checklist’ to determine whether the proposal qualifies as a ‘major development’

South Bucks District Council vi  Determining whether the development requires an air quality assessment or emissions assessment using the ‘Air Quality and emission mitigation assessment checklist’;  Determining whether an air quality assessment is required to assess the impact on public health and/or the local environment as well as the significance of a development on local air quality;  Determine which mitigation measures are required to render the development acceptable on the grounds of air quality and minimise the possibility of the application being refused.

The guidance should be available on the council’s website in July 2018. A joint application was made with Aylesbury Vale, Chiltern and Wycombe District Councils to retrofit a number of buses whose route travelled through AQMAs in each district. Unfortunately the application was not successful. An application was made to apply for funding from the Air Quality Grant to fund a project in Iver. The project was described as a package of measures required to reduce concentrations of air pollution in Iver and areas surrounding the Motorways in South Bucks. These measures combined with further monitoring and modelling, were to be used as a basis for assessing whether a Non-charging Clean Air Zone would be the best method to improve air quality in the area and also to ensure that the concentrations of air pollution do not increase as a result of National Infrastructure Projects and local development. The bid for funding was required to commission a feasibility study to determine whether a non-charging Clean Air Zone would improve air quality and resources in a way that delivers both health benefits and supports economic growth to both Iver and the areas surrounding the Motorways in South Bucks. However the bid was not successful.

As part of the new shared service with Chiltern District Council the current AQMA will be reviewed as well as the Air Quality Action plan to include the new AQMA in Iver. SBDC will also be looking at funding options later in the year

South Bucks District Council vii Conclusions and Priorities The results of the air quality monitoring have not varied significantly in the last 5 years. However it has become apparent that in certain areas of South Bucks the number of HGVs in the area has been increasing and is likely to continue as a consequence of the projects outlined below. South Bucks is continually reviewing its monitoring locations to ensure that they best reflect the air quality in the district. A detailed assessment was carried out in 2016 predominantly in Iver Village. A number of areas were modelled as potentially breaching the annual mean objective for NO2. Additional diffusion tube monitoring stations were set up in January 2017 and the results are provided in Annex A. At a number of these locations concentrations of NO2 was measured above the annual mean objective. Therefore South Bucks District Council is now in the process of declaring an AQMA in Iver using the Fast Track method introduced in 2016.

The new local developments that require more detailed consideration at this time are: Proposed redevelopment of Wilton Park, Beaconsfield and the A355 Improvements Project – The A355 provides the main north-south route through the South Bucks District, connecting Amersham and the A413 in the north to Beaconsfield and the M40, and on to Slough in the south. As a result it accommodates high volumes of traffic, comprising high proportions (up to 55%) of through traffic. The project will deliver improvements to reduce congestion, particularly at the London End roundabout where congestion will be halved, and to improve journey times on this key connection to the M40. The scheme was granted full panning consent in September 2017 with the aim of beginning construction in spring 2018 to be completed by 2019 in time for the beginning of the HS2 project. The A355 Improvements Scheme will be delivered in two parts:

South Bucks District Council viii  Bucks County Council is delivering the Northern section from Maxwell Road to Minerva Way.  Inland Homes is delivering the Southern section from Minerva Way to Pyebush roundabout (which will also include an access road to Wilton Park housing site). The Southern Section gained planning approval in October 2014. South Bucks District Council has received an outline planning application to redevelop Wilton Park. The application comprises of 304 residential properties (Class C3); employment and community uses including new ATC facility (Classes A1, A3, B1, B2, D1 & D2); formal and informal public open space, including local park and sports pitches with changing facilities; new access road from A40 Pyebush Roundabout to form southern part of Beaconsfield Relief Road; network of footpaths and cycle ways including alterations to Minerva Way; car parking; on-site access roads; and landscaping works. As consultees the Strategic Environment team for both Councils will work with planning to ensure that the development will support sustainable travel as outlined in the SPD but to also include the installation of Electric Vehicle charging points.

The Ivers As mentioned above it has become apparent over recent years that there has been an increase in the number of HGVs travelling through the Ivers. The National Infrastructure projects outlined below are also likely to increase NO2 concentrations. This has prompted Bucks CC to carry out a number of traffic studies. The first stage of the study, the Traffic and Transport study has now been completed and can be found here - Iver traffic and transport study | Buckinghamshire County Council The traffic audit carried out as part of the project mentioned above identified the following.

 The Department for Transport publication Road Traffic Estimates Great Britain 2014 identifies that HGVs make up 5.1% of traffic on all roads. For motorways HGVs form 11% of traffic, but only 1.4% on minor roads. These are averages

South Bucks District Council ix across all roads throughout the country. It is evident from the Automatic Traffic Counter (ATC) outputs that almost all locations throughout the Study Area have HGV levels above the national average for all roads. Thorney Lane North and South, Ritchings Way, High Street, Church Road, Sutton Lane all have HGV proportions above the average identified for motorways. Bangors Road South is marginally below the 11% HGV daily level for motorways.  The Origin/Destination survey data is also indicating that approximately two- thirds of the HGV traffic heading north on Thorney Lane North is associated with the three industrial sites accessed from Thorney Lane North. The northbound HGV traffic associated with these sites splits directionally 68% towards Wood Lane, 15% towards Bangors Road South, 10% to Iver Lane and 7% to Langley Park Road.

The Ivers Members Liaison Group (IMLG), a councillor steering group formed of elected representatives from Buckinghamshire County Council, South Bucks District Council and Iver Parish Council, has recently been formed. The group will use the recommendations of the traffic study below plus other local knowledge and proposals to drive forward a comprehensive mitigation plan for the Ivers over the coming months. The primary focus of the group is to promote and develop plans for an Iver Relief Road. There is also concern that the area will be impacted on by a series of proposed national infrastructure projects including:-  The Crossrail project is nearly complete and its due to be finished and the line opened in 2019. The new Queen Elizabeth line will provide more frequent faster trains from Taplow, Iver and Langley into and across London. It is expected to increase the capacity and therefore the patronage to these stations. South Bucks District Council will work with other agencies to promote sustainable travel to these stations so to avoid an increase in pollution.  Upgrade M4 Jct. 4 – 8/9 to a Smart Motorway. In September 2016 the Secretary of State gave planning consent for this project. The Development

South Bucks District Council x Consent Order lists requirements that Highways England and its contractors are obliged to fulfil. This includes monitoring for NO2 at receptors where modelling has indicated that the objective will fail. South Bucks District Council along with other neighbouring authorities is in the process of negotiating with Highways England (HE) over the location and number of diffusion tubes required. It is envisaged that once complete Air Quality surrounding the motorway will improve. However HE must ensure mitigation measures are in place to minimise impact on nearby residents during the construction phase which will begin in 2018.

 Western Rail access for Heathrow. As part Network Rail’s upgrade plan there is a proposal to build a new rail tunnel to link the Great Western Mainline at Reading to London Heathrow Terminal 5. Network Rail have already identified potential impacts from construction including exhaust emissions, dust emissions as well as impact from permanent changes in traffic flows during the pre-application consultation process. Consequently they have suggested a number of mitigation methods such as locating equipment away from receptors and limiting vehicle movements within a specified period have already been put forward. An application for a Development Control Order is being submitted in 2018 with the aim of beginning the project in 2019. Further information on this project can be found on https://www.networkrail.co.uk/our-railway-upgrade-plan/key- projects/heathrow-rail-link/  HS2 Phase 1 – Since Royal Assent of the HS2 (London –West Midlands Act) at the beginning of 2017 enabling works contractors (EWCs) have been carrying out ground investigations and creating habitats. To date enabling works were not predicted (and unlikely) to have had any significant impacts on air quality. EWC activities are expected to increase during 2018 into 2019 and Officers will continue to engage with the EWCs and assess the potential effect of the programme on air quality. Main works civils contractors (MWCCs) are

South Bucks District Council xi currently finalising costings and designs ahead of the “Stage 2 Notice to Proceed” expected first quarter of 2019. As main works start more air quality monitoring will be undertaken in accordance with Section 7 of the Code of Construction Practice (CoCP) by HS2. They will monitor for dust and air pollution, provide monthly reports that include a summary of the construction activities occurring, any complaints received, the data recorded over the monitoring period broken down into appropriate time periods, any periods in exceedance of the agreed trigger levels and the results of any investigations and identified source; and, where the works have been found to be the source, any action taken to immediately resolve the issue and to prevent a recurrence. In addition to this, Officers have located NO2 diffusion tubes within the district at sites identified as potential lorry routes which might be used by the project. When combined with HS2’s reporting, the data from these will help officers assess whether impacts from NO2 levels have occurred. The Council will continue to work on behalf of its residents to ensure that there are no breaches of the environmental minimum requirements which underpin the Act. If a breach occurs in relation to air quality commitments it will be reported to the Secretary of State.

 Heathrow Express Depot relocation proposal to Langley. According to the public consultation on the DCO for the Western Rail link to Heathrow the proposal to relocate the Heathrow Express depot to Langley, as part of the HS2 project, is no longer required and this is why it is not included in their design or assessments.  Heathrow Third Runway proposals On 25 October 2016, the Government confirmed that Heathrow is its preferred option for expansion of airport capacity in the South East. The Government is now expected to put in place a National Policy Statement during 2017/18 in order to establish the necessary policy framework against which the third runway proposal will be considered

South Bucks District Council xii and consented. The secretary of state for Transport stated in October 2016 that “This Government will only grant development consent if we remain satisfied that a new runway will not impact on the UK’s compliance with its air quality obligations.” As consultees South Bucks District Council will work with Heathrow Airport to minimise the impact of potential increase in ground traffic possibly during the construction but more so during the operational phase of the development. Currently officers attend the Heathrow Strategic Planning group along with other host authorities.

Five new nitrogen dioxide diffusion tubes were placed within the district in 2017. Two sites were identified to monitor pollution from the M25 and are located as near as possible to sensitive receptors. Two more were added in Farnham Common near Burnham Beeches. Another was placed outside Iver Village Junior School. Local Engagement and How to get Involved Further information relating to air quality can be found on the council’s award winning web page: http://www.bucksairquality.co.uk/ The new Travel to Beaconsfield and Gerrards Cross maps produced by Bucks County Council provides information on how to travel sustainably from one town to the other. Electronic copies can be found on http://www.buckscc.gov.uk/services/transport-and-roads/buses-and-trains/bus -cycle- and-walking-route-maps/ The site provides a wealth of information suitable for all backgrounds and ages on air quality. It has been developed following requests and feedback from local schools interested in air quality and environmental issues, and residents that need more detailed information.

South Bucks District Council LAQM Annual Status Report 2018 37 1 Local Air Quality Management This report provides an overview of air quality in South Bucks District Council during 2017. It fulfils the requirements of Local Air Quality Management (LAQM) as set out in Part IV of the Environment Act (1995) and the relevant Policy and Technical Guidance documents. The LAQM process places an obligation on all local authorities to regularly review and assess air quality in their areas, and to determine whether or not the air quality objectives are likely to be achieved. Where an exceedance is considered likely, the local authority must declare an Air Quality Management Area (AQMA) and prepare an Air Quality Action Plan (AQAP) setting out the measures it intends to put in place in pursuit of the objectives. This Annual Status Report (ASR) is an annual requirement showing the strategies employed by South Bucks District Council to improve air quality and any progress that has been made.

The statutory air quality objectives applicable to LAQM in England can be found in Table E.1 in Appendix E.

South Bucks District Council LAQM Annual Status Report 2018 37 2 Actions to Improve Air Quality 2.1 Air Quality Management Areas Air Quality Management Areas (AQMAs) are declared when there is an exceedance or likely exceedance of an air quality objective. After declaration, the authority must prepare an Air Quality Action Plan (AQAP) within 12-18 months setting out measures it intends to put in place in pursuit of compliance with the objectives. A summary of AQMAs declared by South Bucks District Council can be found in Table 2.1. Further information related to declared or revoked AQMAs, including maps of AQMA boundaries are available online at www.southbucks.gov.uk/review-and- assessment. Alternatively, see Nitrogen Dioxide fall off with distance calculations These were carried out on all measurements within the AQMA where located near relevant exposure and where concentrations were measured above the national objective.

South Bucks District Council LAQM Annual Status Report 2018 3 2.2 Progress and Impact of Measures to address Air Quality in South Bucks District Council Defra’s appraisal of last year’s ASR concluded the following 1. The current monitoring sites within the AQMA are measuring concentrations below the objective. Consequently Defra recommends an increase in the number of monitoring sites within the AQMA to ensure that the monitoring reflects concentrations of air pollution around the motorway. 2. More information is required on the actions which were taken within the AQAP in the previous 12 months.

3. That future actions added to the AQAP is relevant to improving air quality within the AQMA and the district. Conversely they are aware that the AQMA is declared around motorways and this may prove difficult due to lack of control on whom and what uses the roads. South Bucks District Council has taken forward many direct measures during the current reporting year of 2017 in pursuit of improving local air quality. Details of all measures completed, in progress or planned are set out in Table 2.2. More detail on these measures can be found in their respective Action Plans. Key completed measures are:  The number of monitoring sites along Iver High Street and Thorney Lane South were increased as recommended in the conclusion of the Detailed Assessment for Iver. A review of the monitoring stations for the current AQMA was undertaken to ensure they truly reflect emissions form the motorway. Three more monitoring points were added in 2018 in addition to those suggested as part of the M4 motorway consultation. Monitoring locations already in place were also revised to ensure they were in the best place to adequately reflect the emissions from motorway traffic.

South Bucks District Council LAQM Annual Status Report 2018 4  Working with planning policy on the emerging local plan to ensure that policies are in place to reduce air pollution but also maintain areas of air quality in the future. The council has also been working on the introduction of a local planning guidance for developers based on other tried and tested local guidance already in place elsewhere in the country. The guidance is based on a stepped assessment and uses Defra’s damage cost approach. Good examples cited in the IAQM EPUK Land-Use Planning & Development Control: Planning for Air Quality guidance are the Air Quality and emissions mitigation guidance for Sussex authorities and West Yorkshire’s Air Quality and Emissions Planning Guidance  As previously mentioned in this report a number of National Infrastructure Projects (NIP) will be taking place in the next 5 years. In 2017 South Bucks District Council focused on ensuring that these projects will not unduly affect the residents of its district. This involved attending NIP planning group meetings and responding to a number of complex consultations.  In 2017 the council were required to respond to consultations to ensure compliance with the requirements of the DCO for the M4 Smart Motorway. This included making sure that the requirement to set up a suitable air quality monitoring programme for both the construction and operational phase of the project will be done. The council worked with Highways England as well Slough and Wokingham on this project.

 As a member of the Heathrow Strategic Partnership Group the council has been responding to the first round of consultation for the third runway in Heathrow. However consultation on Air Quality specifically will not take place until 2018 when scoping for the Environmental Impact Assessment will take place.  Buckinghamshire’s statutory Local Transport Plan 4 is committed to developing a new Freight Strategy; ensuring freight continues to help

South Bucks District Council LAQM Annual Status Report 2018 5 Buckinghamshire grow, thrive and develop. In response, they have developed a Draft Freight Strategy to help balance the need for efficient distribution of goods with the needs of our environment and communities. The draft strategy will be consulted upon in 2018 and the Strategic Environment team will take the opportunity to ensure that Air Quality given high priority in this document.  Worked with other District Councils within Buckinghamshire and Arriva buses to apply for funding to retrofit buses which travelled through a number of AQMAs in the County. The bid was unsuccessful. Not being a priority area in the national NO2 plan was cited as one of the reasons the bid was not successful.

 South Bucks District Council expects the following measures to be completed over the course of the next reporting year:  Continue to work with Highways England on implementing the Smart Motorway project on the M4 by responding to consultations and assist with their NO2 monitoring programme. Once operational it is anticipated that the opening of the hard shoulder to traffic when required would allow free running of traffic on the Motorway and reduce emissions.  As part of the Heathrow Strategic Planning Group the council will respond to the consultation on the scoping of the Environmental Impact Assessment prepared for the DCO.

 Respond to consultations on the Freight Strategy  Work with BCC to increase the awareness of Air Pollution within Buckinghamshire and the benefits of joint working by organising a workshop for officers and politicians in spring 2018.

South Bucks District Council LAQM Annual Status Report 2018 6  Due to lack of control by the local councils on the use of motorways by traffic, South Bucks Councils will encourage Defra to implement schemes to support more sustainable travel nationally by responding to consultations such as the recent draft plan on reducing Nitrogen Dioxide in the UK. South Bucks District Council’s priorities for the coming year are  To use current policies and procedures in place to minimise the impact of National infrastructure development and Local development on air quality and to also influence future policies.

 The Local Plan for Chiltern District Council is in the process of being updated. It is a priority for the Strategic Environment team that Air Quality has been given the attention required to enable the Council to allow future development without compromising Air Quality. The team have responded to all internal and external consultations drawing the attention of planning policy to potential issues. This includes the development of local guidance which should be available mid-2018.  To introduce a scheme to reduce the impact of HGVs on local areas. The Strategic Environment team will consider a number of measures over the next year. This will include the possible introduction of a Clean Air Zone. The principal challenges and barriers to implementation that South Bucks District Council anticipates facing are  The current AQMA is surrounding Motorways which are predominantly used to travel long distances. Therefore the Council has little control over who uses them and when.

 There are a number of National Infrastructure Projects being developed in the area. Whilst policies and procedures are in place to enable the Council to have some influence on the projects, these are limited.

South Bucks District Council LAQM Annual Status Report 2018 15 2.3 PM2.5 – Local Authority Approach to Reducing Emissions and/or Concentrations As detailed in Policy Guidance LAQM.PG16 (Chapter 7), local authorities are expected to work towards reducing emissions and/or concentrations of PM2.5 (particulate matter with an aerodynamic diameter of 2.5µm or less). There is clear evidence that PM2.5 has a significant impact on human health, including premature mortality, allergic reactions, and cardiovascular diseases.

South Bucks District Council attend the Health Protection Committee meetings on behalf of BAQMG and will continue to use this platform to stress the importance of reducing PM2.5 concentrations on public health and to encourage the Director of Public Health and other departments in Bucks County Council to work with the team to improve air quality. A small task group has been put in place to organise a workshop which will raise awareness of Air Quality and Public Health in Buckinghamshire. The aim of the workshop is to bring together stakeholders from across the county including officers and politicians to discuss the current situation in Buckinghamshire and to identify the best way to work together in the future to reduce concentrations of PM2.5 and NO2 in the county. The workshop will take place in spring 2018.

South Bucks District Council LAQM Annual Status Report 2018 16 3 Air Quality Monitoring Data and Comparison with Air Quality Objectives and National Compliance 3.1 Summary of Monitoring Undertaken 3.1.1Automatic Monitoring Sites This section sets out what monitoring has taken place and how it compares with objectives. South Bucks District Council closed its automatic (continuous) monitoring site at Gerrards Cross during 2016. Non-Automatic Monitoring Sites South Bucks District Council undertook non- automatic (passive) monitoring of NO2 at 29 sites during 2017. Table A.1 in Appendix A shows the details of the sites. Maps showing the location of the monitoring sites are provided in Appendix D. Further details on Quality Assurance/Quality Control (QA/QC) for the diffusion tubes, including bias adjustments and any other adjustments applied (e.g. “annualisation” and/or distance correction), are included in Appendix C.

3.2 Individual Pollutants The air quality monitoring results presented in this section are, where relevant, adjusted for bias, “annualisation” and distance correction. Further details on adjustments are provided in Appendix C. 3.2.1 Nitrogen Dioxide (NO2) Table A. in Appendix A compares the ratified and adjusted monitored NO2 annual mean concentrations for the past 5 years with the air quality objective of 40µg/m3 . For diffusion tubes, the full 2017 dataset of monthly mean values is provided in Appendix B.

South Bucks District Council LAQM Annual Status Report 2018 17 The annual mean objective for NO2 was exceeded at a 6 monitoring points in 2017. However using the fall off with distance calculation as outlined in TG(16) the exposure level at the nearest sensitive receptor was considerably below the objective for 2 of these sites. Site 4 – Iver Heath Uxbridge Site 14 – North Drive, Beaconsfield The results for site 39/40 Fulmer, Tatling End have been disregarded as the results are not considered representative. Monitoring was started here in October 2017 and in this time some diffusion tubes went missing and one was found on the floor. The remaining 3 sites are in Iver Village located on the High Street or Thorney Lane North/South. The results of the fall off with distance calculation were above the annual mean objective for 2 of these sites and marginally below for one site. As mentioned previously in the report an AQMA will now be declared in Iver. None of the sites recorded annual means above 60µg/m3 , which indicates that there has not been an exceedance of the 1-hour mean objective in South Bucks.

South Bucks District Council LAQM Annual Status Report 2018 29 Appendix C: Supporting Technical Information / Air Quality Monitoring Data QA/QC South Bucks District Council use 20% TEA in water diffusion tubes analysed by Gradko. As South Buck District Council no longer has a continuous monitor to co- locate tubes the National Bias Adjustment Factor was used. The national bias adjustment factor for 2017 is 0.89. In 2017 Gradko scored a 100% in all rounds reported on the Defra website of the AIR- PT scheme.

The precision results for Nitrogen Dioxide diffusion tube collocation studies were determined good in all study results for 20% TEA in Water diffusion tubes in 2017. During 2017 the valid data capture for two diffusion tubes (Grand Union House and Fulmer, Tatling End) was below 75%. Therefore the calculated annual average was annualised according to the method outlined in boxes 7.9 and 7.10 in LAQM TG16. Data from a background monitoring site with more than 85% data capture is required for this calculation. A site known as Hillingdon UKA00266 was chosen from Defra’s Automatic Urban Rural Network (AURN) of monitoring stations. This site was chosen as it was the nearest background site that had sufficient data capture. The calculated ratio is then used to adjust the calculated annual mean before it is bias adjusted. Further details on the Hillingdon monitoring site can be seen below. Hillingdon UKA00266 monitoring station The monitoring station is within a self-contained, air-conditioned housing located on an open grass area approximately 2.5 metres from the kerb of a residential road. The site is bordered on three sides by residential roads and on the fourth by the busy M4 motorway, which is approximately 30 metres from the station and above the height of the inlet. The general area is open and protected from the M4 by trees.
