Wiltshire Council – Updating and Screening Assessment 2009

Executive Summary Wiltshire Council came into existence on April 1st 2009, bringing together the four former Wiltshire local authorities of Kennet District Council, North Wiltshire District Council, Salisbury District Council and West Wiltshire District with Wiltshire County Council. Our combined Updating and Screening Assessment (USA) integrates the Local Air Quality Management (LAQM) reporting duties for our former District Councils into a single document. This document is structured in such a way that Updating and Screening Assessment data for the former District Council areas are reported in individual chapters. For reporting purposes, it should be noted that: • Kennet – refers to the former Kennet District Council area; • North Wiltshire – refers to the former North Wiltshire District Council area; • Salisbury – refers to the former Salisbury District Council area; and • West Wiltshire – refers to the former West Wiltshire District Council area.

There are currently five Air Quality Management Areas within the Wiltshire Council administrative area, these are: • Whole city centre AQMA in the Salisbury area; • London Road (near St Mark’s roundabout) in the Salisbury area; • Wilton Road (near St Paul’s roundabout) in the Salisbury area; • Bradford on Avon in the West Wiltshire area; and • Westbury in the West Wiltshire area.

This combined Updating and Screening Assessment for 2009 has concluded the following:

• Kennet area – Monitoring data has indicated exceedences of the NO2 annual mean objective at Upper Herd Street and Shane’s Castle – both of these locations are being considered in an ongoing Detailed Assessment. No new Detailed Assessment is required based on monitoring data or the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern. • North Wiltshire area - No Detailed Assessment is required based on monitoring data or the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern.

• Salisbury area - Monitoring data has indicated exceedences of the NO2 annual mean objective in the Salisbury AQMAs in 2006, 2007 and 2008, therefore, the AQMAs are still justified. There was one exceedence of the

NO2 annual mean objective outside of the current AQMAs, therefore, a Detailed Assessment is required at Queen Street, Wilton. No Detailed Assessment is required based on the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern.

• West Wiltshire area - Monitoring data has indicated exceedences of the NO2 annual mean objective have in the Bradford on Avon and Westbury AQMAs in 2006, 2007 and 2008, therefore, the AQMAs are still justified. There were no

exceedence of the NO2 annual mean objective outside of the current AQMAs, therefore, no Detailed Assessment is required. No Detailed Assessment is required based on the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern.

Proposed actions for subsequent Review and Assessment reporting duties will include: • Completion and submission of the ongoing Upper Herd Street and Shane’s

Castle Detailed Assessment for NO2 (annual mean objective); • Completion and submission of the Queen Street, Wilton Detailed Assessment

for NO2 (annual mean objective) in 2010; • Completion and Submission of a Review and Assessment Progress Report in 2010; and • Completion and Submission of a Air Quality Action Plan Progress Report in 2010 (this may be integrated in to the Review and Assessment Progress Report).

1.2 Purpose of Report This report fulfils the requirements of the LAQM process as set out in Part IV of the Environment Act (1995), the Air Quality Strategy for England, Scotland, Wales and Northern Ireland 2007 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 exceedences are considered likely, the local authority must then 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.

Wiltshire Council – Updating and Screening Assessment 2009

1.3 Air Quality Objectives The air quality objectives applicable to LAQM in England are set out in the Air Quality (England) Regulations 2000 (SI 928), The Air Quality (England) (Amendment) Regulations 2002 (SI 3043), and are shown in Table 1. This table shows the objectives in units of microgrammes per cubic metre µg/m3 (milligrammes per cubic metre, mg/m3 for carbon monoxide) with the number of exceedences in each year that are permitted (where applicable).

2 Chapter 2 - Requirements for an Updating and Screening Assessment A USA is intended to identify any significant changes that may have occurred since the previous rounds of Review and Assessment. Our USA includes new monitoring data, new or changed emissions sources or any other local changes that might affect air quality. In undertaking a USA, local authorities should draw upon the work that has been completed in previous rounds of Review and Assessment and pay heed to the revised LAQM Technical Guidance (LAQM.TG(09)) and LAQM Policy Guidance (LAQM.PG(09)) documents and any subsequent FAQs, additional guidance etc. The following section summaries the requirements for a USA that have been adhered to for each of the four former Wiltshire Council’s with regards to new monitoring data and the screening of potential sources of air pollution.

2.1 Requirements for new monitoring data New, and where appropriate historical, monitoring data should be reviewed and assessed against the Air Quality Objectives, in accordance with the guidance set out in LAQM.TG(09), to determine whether an exceedence is likely or not. Local monitoring data, monitoring data from neighbouring authorities (if relevant) and data from the national monitoring networks can be collated and utilised in order to assess the level of risk. Monitoring data will play an increasingly important role in the Review and Assessment process as many of the Air Quality Objectives are now ‘live’. Monitoring data may be used to identify new locations where there is a risk of exceedence of one or more of the Air Quality Objectives, or to provide evidence that a previously declared AQMA requires reconsideration. For further information on specific requirements for new monitoring data see LAQM.TG(09), Box 5.3.

2.2 Requirements for Road Traffic Sources The focus of attention for road traffic sources in Round 4 of Review and Assessment is on relevant locations close to busy roads, especially in congested areas and near to junctions, where emissions will be higher, and in built up areas where the road is canyon like, with buildings on either side of the road restricting dispersion and dilution of the emissions.

2.2.1 A1 - Narrow congested streets with residential properties close to the kerb Consideration has been given to locations where traffic is slow moving, with stop/start driving, and where buildings on either side reduce dispersion. This

Wiltshire Council – Updating and Screening Assessment 2009

element of the Updating and Screening Assessment only considers NO2. Further information on the detailed criteria followed can be found in Section A1, Box 5.3 of LAQM.TG(09).

2.2.2 A2 - Busy streets where people may spend 1-hour or more close to traffic Consideration has been given to streets with many shops and/or outdoor cafes and bars where people may be expected to regularly spend 1-hour or more. This element of the Updating and Screening Assessment only considers NO2. Further information on the detailed criteria followed can be found in Section A2, Box 5.3 of LAQM.TG(09).

2.2.3 A3 - Roads with high flow of buses and/or HGVs Consideration has been given to street locations where traffic flows are not necessarily high but there is an unusually high proportion of buses and/or HGVs.

This element of the Updating and Screening Assessment considers both NO2 and

PM10. Further information on the detailed criteria followed can be found in Section A3, Box 5.3 of LAQM.TG(09).

2.2.4 A4 - Junctions Pollution concentrations may be higher close to junctions due to both the combined impact of traffic emissions on two or more roads and the influence of stop/start traffic. Consideration has been given to junctions of this type. This element of the Updating and Screening Assessment considers both NO2 and PM10. Further information on the detailed criteria followed can be found in Section A4, Box 5.3 of LAQM.TG(09).

2.2.5 A5 - New roads constructed or proposed since the last round of Review and Assessment. Consideration has been given to new roads constructed or proposed since the last round of Review and Assessment. This element of the Updating and Screening

Assessment considers both NO2 and PM10. Further information on the detailed criteria followed can be found in Section A5, Box 5.3 of LAQM.TG(09).

2.2.6 A6 - Roads with significantly changed traffic flows. This section of the Updating and Screening Assessment only consider those roads that have not been assessed in Sections 2.3.2 to 2.3.5 above. A significant increase can be considered as a 25% increase in traffic flow on any road with more than

Wiltshire Council – Updating and Screening Assessment 2009

10,000 vehicles per day. This element of the Updating and Screening Assessment considers both NO2 and PM10. Further information on the detailed criteria followed can be found in Section A6, Box 5.3 of LAQM.TG(09).

2.2.7 A7 - Bus and coach stations. This section considers bus stations or section of bus stations that are not enclosed, and where relevant exposure exists. This element of the Updating and Screening

Assessment considers both NO2 objectives (annual mean and 1-hour). Further information on the detailed criteria followed can be found in Section A7, Box 5.3 of LAQM.TG(09).

2.3 Requirements for Other Transport Sources Most sources in this section have been considered in previous rounds of Review and Assessment however future consideration may be required where there have been substantial change, where new relevant exposure exists or if a busy railway line with diesel locomotives goes through a local authority’s area.

2.3.1 B1 - Airports Consideration has been given to airports with >10 million passengers per annum (100,000 tonnes freight = 1mppa) and with relevant exposure within 1000m of the airport boundary. This element of the Updating and Screening Assessment considers just NO2 (consideration of PM10 has been removed from the new Technical Guidance). Further information on the detailed criteria followed can be found in Section B1, Box 5.4 of LAQM.TG(09).

2.3.2 B2(a) - Railways (SO2) Consideration has been given to locations where locomotives, diesel or coal fired, are regularly stationary for period of 15 minutes or more and where relevant exposure exists. This element of the Updating and Screening Assessment considers just SO2. Further information on the detailed criteria followed can be found in Section B2, Box 5.4 of LAQM.TG(09).

2.3.3 B2(b) - Railways (NO2) Consideration has been given to sections of tracks with large numbers (>300) 3 moving diesel locomotives, with background NO2 concentrations >25µg/m and relevant exposure with 30m of the edge of the tracks. This element of the Updating and Screening Assessment considers just NO2. Further information on the detailed

Wiltshire Council – Updating and Screening Assessment 2009 criteria followed can be found in Section B2, Box 5.4 of LAQM.TG(09) and in the associated FAQ on the Review and Assessment Website (http://www.uwe.ac.uk/aqm/review/FAQ_Railway_Locomotives_100209.pdf).

2.3.4 B3 - Ports (Shipping) Consideration is given to ports where large ships generally burn oils with high sulphur content in their main engines (bunker oils). This element of the Updating and

Screening Assessment considers just SO2. Further information on the detailed criteria followed can be found in Section B3, Box 5.4 of LAQM.TG(09)

2.4 Requirements for Industrial Sources Industrial sources are controlled by the Environment Agency (EA) and by local authorities under the Pollution Prevention and Control regulations and through the Clean Air Act. Many of these sources have bee previously assessed in detail in previous Rounds of Review and Assessment, therefore focus in this Updating and Screening Assessment is primarily on new installations and those with significantly changed emissions. This section considers all of the regulated pollutants although those most at risk included SO2, NO2, PM10 and Benzene.

2.4.1 C2(a) - New or proposed installations for which an Air Quality Assessment has been carried out. Consideration has been given to any new or proposed industrial installations for which an Air Quality Assessment has been carried out. Further information on the detailed criteria followed can be found in Section C1, Approach 1, Box 5.5 of LAQM.TG(09)

2.4.2 C1(b) - Existing installations where emissions have increased substantially or new relevant exposure has been introduced. Consideration has been given to any existing industrial installations where emissions have increased substantially or new exposure introduced. Further information on the detailed criteria followed can be found in Section C1, Approach 2, Box 5.5 of LAQM.TG(09)

2.4.3 C1(c) - New or significantly changed installations with no previous Air Quality Assessment Consideration has been given to any new or significantly altered industrial installations for which no Air Quality Assessment has been produced. Further

Wiltshire Council – Updating and Screening Assessment 2009 information on the detailed criteria followed can be found in Section C1, Approach 3, Box 5.5 of LAQM.TG(09)

2.4.4 C2 - Major fuel storage depots (Petrol) There is the potential for major fuel depots (petrol) to emit benzene and risk exceeding the 2010 objective. This element of the Updating and Screening Assessment considers Benzene only. Further information on the detailed criteria followed can be found in Section C2, Box 5.5 of LAQM.TG(09)

2.4.5 C3 - Petrol stations Petrol stations combined with nearby busy roads may potentially emit sufficient benzene to risk exceeding the 2010 objective. Consideration has been given to all petrol stations with an annual throughput of more than 2000m3 of petrol, with busy roads close by and relevant exposure with 10m of the petrol station pumps. This element of the Updating and Screening Assessment considers Benzene only. Further information on the detailed criteria followed can be found in Section C3, Box 5.5 of LAQM.TG(09)

2.4.6 C4 - Poultry farms Previous rounds of Review and Assessment have identified the potential exceedences of the PM10 objectives associated with emissions from poultry farms (defined as chickens (laying hens and broilers), turkeys, ducks and guinea fowl). Consideration has been given to any farms housing in excess of 400,000 birds (mechanically ventilated), 200,000 birds (naturally ventilated) or 100,000 turkeys (any ventilation) where relevant exposure exists with 100m. This element of the Updating and Screening Assessment considers PM10 only. Further information on the detailed criteria followed can be found in Section C4, Box 5.5 of LAQM.TG(09)

2.5 Requirements for Commercial and Domestic Sources Commercial (including the service sector) and domestic sources need to be considered in relation to biomass combustion and the use of domestic solid-fuel usage. The process of combustion of biomass material may result in an increase in

PM10 and NOX emissions.

2.5.1 D1(a): Biomass combustion – individual installations Consideration has been given to large individual installations (50kW to 20MW in size) burning biomass. This element of the Updating and Screening Assessment

Wiltshire Council – Updating and Screening Assessment 2009

considers PM10 and NO2. Further information on the detailed criteria followed can be found in Section D1a, Box 5.8 of LAQM.TG(09).

2.5.2 D1(b) - Biomass combustion – combined impacts Numerous small biomass combustion units, while acceptable individually, may have a cumulative impact on PM10 concentrations. This element of the Updating and

Screening Assessment considers PM10 only. Further information on the detailed criteria followed can be found in Section D1b, Box 5.8 of LAQM.TG(09).

2.5.3 D2 - Domestic solid-fuel burning Consideration has been given to locations where domestic solid-fuel burning (coal) may give rise to exceedences of the SO2 objectives. This element of the Updating and Screening Assessment considers SO2 only. Further information on the detailed criteria followed can be found in Section D2, Box 5.8 of LAQM.TG(09).

2.6 Requirements for Fugitive or Uncontrolled Sources

Fugitive or uncontrolled sources may give rise to emissions of PM10. This section considers numerous sources such as quarries, landfill sites, stockyards, construction work and waste management site. Consideration has been given to elements such as: • the passage of vehicles over unpaved roads; • handling of dust materials; • process dust e.g. concrete cutting; and • windblown dust from stockpiles and dusty surfaces.

This element of the Updating and Screening Assessment considers PM10 only. Further information on the detailed criteria followed can be found in Section E1, Box 5.10 of LAQM.TG(09).

3 Chapter 3 - Updating and Screening Assessment for Kennet 3.1 Summary of previous round of Review and Assessment for Kennet Kennet District Council submitted an Updating and Screening Assessment for Round 3 of Review and Assessment in 2006 and subsequently has submitted an annual Review and Assessment Progress Report in 2007 and 2008. A Detailed Assessment for NO2 (annual mean) at Upper Herd Street, Marlborough and Shane’s Castle, Devizes is currently ongoing. There are no Air Quality Management Areas within the former Kennet District Council area of Wiltshire Council.

3.2 New monitoring data - Kennet

Since the last round of Review and Assessment only monitoring for NO2 using nitrogen dioxide diffusion tubes has been carried out.

3.2.1 Summary of monitoring undertaken – Automatic Since the last round of Review and Assessment no continuous monitoring has been carried out.

3.2.2 Summary of monitoring undertaken – Diffusion Tube

NO2 has been monitored in 2008 used diffusion tubes supplied and analysed by Lambeth Scientific Services (50% Tea in Acetone). The diffusion tubes have a monthly exposure period. There are no co-location studies so the diffusion tube bias adjustment factors are generated from the National Bias Adjustment Factor Spreadsheet available on the Review and Assessment Website (v05/09). The following bias adjustment factors have been applied to the data presented in this report: • 2006 - 1.28 (based on 10 studies) • 2007 - 1.07 (based on 13 studies) • 2008 - 0.97 (based on 9 studies)

All of the 2008 diffusion tube data has been annualised, as required, according to the guidance in LAQM.TG(09). Table 2 below provides diffusion tube site description information and Table 3, Table 4 and Table 5 provide the diffusion tube data for 2006, 2007 and 2008 respectively. Maps of the Kennet monitoring sites can be found in Appendix 1. Lambeth Scientific Services participate in the WASP Scheme and have performed ‘good’ the January 2008 – January 2009 report published on the LA Support Helpdesk Website.

3.2.3 Comparison of monitoring results with the Air Quality Objectives for Kennet Continuous monitoring: No continuous monitoring was undertaken during 2006-2008 of Review and Assessment.

Nitrogen Dioxide Diffusion Tubes: The 2008 nitrogen dioxide diffusion tube data as indicated exceedences of the annual mean objective at the following locations: • Upper Herd Street (at four diffusion tube locations); • Trafalgar Place (at two diffusion tube locations); • Shanes Castle (at two diffusion tube locations); and • Devizes opposite Roses.

There is no relevant exposure at the Trafalgar Place and Devizes opposite Roses diffusion tube locations. Relevant exposure does exist at Upper Herd Street and Shane’s Castle. Both of these locations are being considered in an ongoing Detailed Assessment.

Measured concentrations of NO2 achieve the air quality objectives at all locations except Upper Herd Street and Chanes’s Castle which are currently being considered in an ongoing Detailed Assessment. No further work is required in relation of this section.

3.3 Screening of Sources of Emissions for Kennet

The following tables (Table 6, Table 7, Table 8, Table 9 and Table 10) summarise the screening of potential sources of emissions in the Kennet area following the criteria set out in LAQM.TG(09). For further information on the specific screening criteria please see Chapter 2 of this document and Chapter 5 of LAQM.TG(09). Where available additional supporting evidence has been provided to highlight how conclusions have been established. Those boxes shaded in green indicate that no further work is required (i.e. a Detailed Assessment is not required), conversely, those boxes shaded in yellow indicate that further work is required (i.e. a Detailed Assessment is required).

4 Chapter 4 - Updating and Screening Assessment for North Wiltshire

4.1 Summary of previous Review and Assessments for North Wiltshire North Wiltshire District Council submitted an Updating and Screening Assessment for Round 3 of Review and Assessment in 2006 and subsequently has submitted an annual Review and Assessment Progress Report in 2007 and 2008. There are no Air Quality Management Areas within the North Wiltshire area of Wiltshire Council.

4.2 New monitoring data – North Wiltshire Since the last round of Review and Assessment, North Wiltshire has primarily undertaken monitoring for NO2 and PM10 using both continuous analysers and nitrogen dioxide diffusion tubes.

4.2.1 Summary of monitoring undertaken – Automatic Since the last round of Updating and Screening Assessment, two programmes of continuous monitoring have been carried out at two locations in the North Wiltshire area, namely: 1 • Wootton Bassett for NO2 and PM10 (September 2006 – February 2007); and 2 • Cricklade for NO2 and PM10 (November 2007 – March 2008)

Wootton Bassett Study: The continuous analyser was located at a roadside site on the High Street between the 8th September and 29th October 2006 and between the 16th January and 20th February 2007. The monitoring station comprised of a self- contained air-conditioned unity equipped with a Met One BAM 1020 Dust Monitor without a heated inlet for measuring PM10 concentrations and an API M200A chemileminscence monitoring for measuring NO2 concentrations. All data reported has been adjusted appropriately and has suitable QA/QC (for more detailed information please see the referenced report). Measured concentrations indicate no exceedences of the NO2 or PM10 objectives (Table 11).

Cricklade Study: The continuous analyser was located at a roadside site on the High Street between the 30th November 2007 and 11th March 2008. The monitoring station comprised of a self-contained air-conditioned unity equipped with a Met One

BAM 1020 Dust Monitor without a heated inlet for measuring PM10 concentrations and an API M200A chemileminscence monitoring for measuring NO2 concentrations.

4.2.2 Summary of monitoring undertaken – Diffusion Tube

NO2 has been monitored at sixteen locations in the North Wiltshire area using diffusion tubes supplied and analysed by Bristol Scientific Services (20% Tea in Water). The diffusion tubes have a monthly exposure period. There are no co- location studies so the diffusion tube bias adjustment factors are generated from the National Bias Adjustment Factor Spreadsheet available on the Review and Assessment Website (v05/09). The follow bias adjustment factors have been applied to the data presented in this report: • 2006 - 0.90 (based on 5 studies) • 2007 - 0.77 (based on 5 studies) • 2008 - 0.87 (based on 4 studies)

In 2008, a substantial period of diffusion tube data is missing as a new technical officer was mistakenly removing the incorrect cap from the diffusion tubes. All of the 2008 diffusion tube data has been annualised according to the guidance in LAQM.TG(09). Table 12 below provides diffusion tube site description information and Table 13, Table 14 and Table 15 provide the diffusion tube data for 2006, 2007 and 2008 respectively. Maps of the North Wiltshire monitoring sites can be found in Appendix 2. Bristol Scientific Services participate in the WASP Scheme and have performed ‘good’ in the January 2008 – January 2009 report published on the LA Support Helpdesk Website.

5 Chapter 5 - Updating and Screening Assessment for Salisbury 5.1 Summary of previous Review and Assessments – Salisbury In the last round of Review and Assessment, Round 3, Salisbury District Council submitted an Updating and Screening Assessment in 2006 and subsequently submitted a Detailed Assessment in 2007 (for nitrogen dioxide annual mean objective) and a Progress Report in 2008.

The Detailed Assessment for nitrogen dioxide, and subsequent Further Assessment, concluded that three Air Quality Management Areas were required (declared in October 2007): • Whole city centre AQMA (incorporating the five AQMAs declared in previous rounds of Review and Assessment); • London Road (near St Mark’s roundabout); and • Wilton Road (near St Paul’s roundabout).

Maps of the Salisbury AQMA and monitoring sites can be found in Appendix 3.

5.2 New monitoring data - Salisbury

This report provides a summary of all available monitoring data for 2006-2008 in a format suitable for comparison with the relevant Air Quality Objectives. In 2008, the following sites were operative in the Salisbury area:

• One automatic analyser in Exeter Street (NO2 and PM10);

• One automatic analyser in Bridge Street (NO2 and PM10); and • Thirty-eight nitrogen dioxide diffusion tube sites (including two triplicate co- location studies at each of the continuous analysers).

5.2.1 Summary of monitoring undertaken – NO2 and PM10

Salisbury has a continuous NO2 APNA 360 chemiluminscence analyser in both Exeter Street and Bridge Street. All data presented in this report has been ratified and adjusted as appropriate according to current guidance. Table 21 provides the

NO2 concentrations from both the Exeter Street and Bridge Street continuous analysers for 2006, 2007 and 2008. There is a triplicate NO2 diffusion tube study at the both continuous analyser. The 2008 precision and accuracy analysis of the data for this study is presented in Figure 1 and Figure 2 below.

Wiltshire Council – Updating and Screening Assessment 2009

Salisbury has a continuous Eberline B gauge PM10 analyser in both Exeter Street and Bridge Street. All data presented in this report has been ratified and adjusted as appropriate according to current guidance. Table 21 provides the PM10 concentrations from both the Exeter Street and Bridge Street PM10 continuous analysers for 2006, 2007 and 2008.

5.2.2 QA/QC of Exeter Street and Bridge Street Continuous Analysers The Exeter Street and Bridge Street sites are managed by Environmental Health Services. Data management and reporting is carried out mainly through the Ambient Air Quality Central Software package IDAZRW. The station is polled automatically from a PC situated at Depot Offices of Environmental Services via a GSM modem. The poll occurs three times daily at 00:00 hours, 08:00 hours and 13:00 hours. The PC remains switched on constantly. Features of the software include: • Automatic calibration every 73 hours • Automatic redial on busy line or after communication failure • Detailed logs of data requests and transmission problems • Remote control of stations for zero test, test gas, measuring range and calibrations • Calculation of scaling factors and application to nearest results following each automatic calibration • Marking of abnormal readings, negative readings or readings taken during instrument failure or calibration • Deletion of abnormal readings

Manual scaling is, therefore, not required. The auto-scaling feature means that the figures are more frequently scaled than the accepted manual scaling operation on a two-weekly basis. Data is checked manually at least weekly, more normally daily, to ensure that the software is making the correct adjustments. There should, therefore, be no requirement to manually back-correct. Abnormal readings are marked. During the calibration checks a manual note is taken of span and zero and NO2 gas readings, any abnormal conditions or error readings and any actions taken. Manual calibrations are compared with auto-calibration. At 6 monthly intervals the data is compared with the nearest AURN site. Any abnormal data will be discarded unless it can be traced to a local event. The correction factors are recorded in the calibration report and any local anomalous results are investigated for example steam cleaning of the street by Environmental Services to remove chewing gum. Data capture for

the Salisbury site was high, with only a small percentage being lost due to calibration, filter changes and head cleaning. It is however reported that there have been problems encountered retrieving data via the modem caused by issues with the IT department who will not proactively check the status of the link following routine server maintenance and upgrades. This has caused loss of data where memory space at the monitoring station has been exceeded. Loss of data has not related to the functioning of the analysers.

5.2.3 Summary of monitoring undertaken – Diffusion Tube The nitrogen dioxide diffusion tubes are 20% TEA in water supplied and analysed by Bristol Scientific Services. The tubes at all locations through out the Salisbury area have a monthly exposure period. Salisbury has a co-location study at their Exeter Street and Bridge Street continuous monitoring sites. Comparison of the ‘local’ bias adjustment factors and the ‘national’ bias adjustment factors (generated from the National Bias Adjustment Factor Spreadsheet available on the Review and Assessment Website (v05/09)) can be found in Table 22 below. A combined bias adjustment factor from the two local co-location studies has been utilised in all years (2006-2008) as this value is approximate yet precautionary compared to the National Bias Adjustment Factor for the respective year. All of the 2008 diffusion tube data has been annualised as required according to the guidance in LAQM.TG(09).

5.2.4 Comparison of monitoring results with the Air Quality Objectives - Salsibury

Continuous monitoring – NO2: Concentrations of NO2 reported in the continuous monitoring studies undertaken at Exeter Street and Bridge Street exceed the annual mean air quality objectives for NO2 in 2006 (both sites), 2007 (one site) and 2008 (both sites). These locations are within the City Centre AQMA. The hourly air quality objective for NO2 was achieved at both monitoring sites.

Continuous monitoring – PM10: Concentrations of PM10 reported in the continuous monitoring studies undertaken at Exeter Street and Bridge Street achieve both the annual mean and 24-hour air quality objectives at both monitoring sites in 2006, 2007 and 2008.

Nitrogen Dioxide Diffusion Tubes: Seventeen diffusion tube sites exceeded the NO2 annual mean objective in 2008. None of the diffusion tubes reported concentrations greater than 60µg/m3 suggesting that the 1-hour air quality objective is not at risk. All of the sites that exceeded the annual mean objective, except two, are within the existing AQMAs. The two sites exceeding the annual mean objective outside of the existing AQMA were: • Southampton Road – Salisbury College: This is a new diffusion tube site which only commenced in December 2008.

• 1 Queen Street, Wilton: This site recorded an annual mean NO2 concentration of 40.4µg/m3, exceeding the annual mean objective of 40µg/m3 (in previous years this site was just below the annual mean objective reporting concentrations of 38.5µg/m3 and 36.3µg/m3 for 2006 and 2007 respectively). Although the 2008 exceedence is marginal, this site is situated at a location where relevant exposure exists and can be considered a worst-case location. It is recommended that this location is considered further in a Detailed Assessment in 2010. •

Measured concentrations of NO2 in 2008 indicate an exceedence of the annual mean air quality objective at one location outside of the existing AQMA – Queen Street, Wilton. It is recommended that this location is considered further in a Detailed Assessment in 2010. The monitoring data for 2008 also indicates that the AQMAs are still justified.

Table 27: Screening for Road Traffic Sources (Salisbury) Section Heading Evidence, Conclusions and Recommendations A1 Narrow congested streets with residential Following the screening criteria in LAQM.TG(09), numerous narrow congested streets properties close to the kerb of potential concern have been identified including Fisherton Street, Castle Street,

Milford Street, Crane Street and Exeter Street. All of these locations have NO2 monitoring in places and all of the Salisbury City Centre roads were assessed in detail in the Further Assessment undertaken in 2007. The roads that have been identified as a potential concern have been previously assessed and fall with the existing Air

Quality Management Areas for NO2, therefore, there are no new narrow congested streets with residential properties close to the kerb of concern. No further work is required in relation to this section.

A2 Busy streets where people may spend 1- Following the screening criteria in LAQM.TG(09) and given consideration to NO2 hour more close to traffic monitoring in Salisbury, there are no busy streets where people may spend 1-hour or more close to traffic of concern or where monitoring data has indicated a potential

concern with regards to the 1-hour air quality objective for NO2 (based on the relationship between the annual mean and 1-hourly objective). No further work is required in relation to this section. A3 Roads with high flows of buses and/or Following the screening criteria in LAQM.TG(09), there is one road link which meets HGVs the criteria. This road link (junction with Castle Street/Blue Boar Row and Minster Street with high flows of buses going to the bus station on Endless Street) was considered in detail in Salisbury’s Detailed Assessment in November 2007. There is

no relevant exposure at this location. No further work is required in relation to this section. A4 Junctions Following the screening criteria in LAQM.TG(09), there are no junctions of concern. No further work is required in relation to this section. A5 New road constructed or proposed since Following the screening criteria in LAQM.TG(09), there are no new roads constructed the last round of Review and Assessment or proposed since the last round of Review and Assessment of concern. No further work is required in relation to this section. A6 Roads with significantly changed traffic Following the screening criteria in LAQM.TG(09), and analysis of ATC data provided flows by Wiltshire County Council (comparing 2005 AADT with 2008 AADT i.e. to establish any significant changes since the last Updating and Screening Assessment) there are no roads of concern identified in the Salisbury area with a significant increase in traffic flows. Only one road has gone above the threshold of >10,000 vehicles per day, namely the A3094, West Harnham. However the traffic flow has only increased by 12.9% based on AADT data between 2005 and 2008. Following the screening criteria in LAQM.TG(09), no further work is required in relation to this section. A7 Bus and coach stations Following the screening criteria in LAQM.TG(09), there are no bus/coach stations of concern in the Salisbury area. No further work is required in relation to bus stations

5.4 Conclusions and Proposed Actions – Salisbury 5.4.1 Conclusions from new monitoring data - Salisbury This Updating and Screening Assessment has concluded that exceedences of the

NO2 annual mean objective have been noted in the Salisbury AQMAs in 2006, 2007 and 2008, therefore, the AQMAs are still justified. There was one exceedence of the

NO2 annual mean objective outside of the current AQMAs, therefore, a Detailed Assessment is required at Queen Street, Wilton. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern.

5.4.2 Conclusions from source assessment - Salisbury This Updating and Screening Assessment has concluded the following: • This assessment has indicated that there are no Road Transport Sources of concern in the Salisbury area, and therefore a Detailed Assessment is not required. • This assessment has indicated that there are no Other Transport Sources of concern in the Salisbury area, and therefore a Detailed Assessment is not required. • This assessment has indicated that there are no Industrial Sources of concern in the Salisbury area, and therefore a Detailed Assessment is not required. • This assessment has indicated that there are no Commercial and Domestic Sources of concern in the Salisbury area, and therefore a Detailed Assessment is not required. • This assessment has indicated that there is no Fugitive or Uncontrolled Sources of concern in the Salisbury area, and therefore a Detailed Assessment is not required.

6 Chapter 6 - Updating and Screening Assessment for West Wiltshire 6.1 Summary of previous Review and Assessment - West Wiltshire West Wiltshire District Council submitted an Updating and Screening Assessment for Round 3 of Review and Assessment in 2006 and subsequently has submitted an annual combined Review & Assessment and AQAP Progress Report in 2007 and 2008. There currently two Air Quality Management Areas (AQMA), both declared in November 2001, in the West Wiltshire area. The Air Quality Management Areas are: • The Bradford on Avon AQMA was declared for exceedences of the annual 3 mean nitrogen dioxide objective of 40µg/m and the 24-hour PM10 objective of 50µg/m3 not to be exceeded more the 35 times per annum due to transport sources. • The Westbury AQMA was declared for exceedences of the annual mean nitrogen dioxide objective of 40µg/m3 due to transport sources.

West Wiltshire District Council submitted a Further Assessment in November 2003 which concluded that the AQMAs were justified as declared. In 2005, West Wiltshire produced an Air Quality Action Plan for both the Bradford on Avon and Westbury Air Quality Management Areas.

6.2 New monitoring data – West Wiltshire This report provides a summary of all available monitoring data for 2006-2008 in a format suitable for comparison with the relevant Air Quality Objectives. In 2008 the following sites were operative in the West Wiltshire area:

• One automatic analyser (NO2) and seven nitrogen dioxide diffusion tubes (three co-located at the automatic analyser) in Bradford on Avon.

• One automatic monitoring station (NO2) and five nitrogen dioxide diffusion sites in Westbury; and • Two nitrogen dioxide diffusion tube sites in Trowbridge.

6.2.1 Summary of monitoring undertaken – Automatic

West Wiltshire has a continuous NO2 chemiluminscence analyser (API M200) in both their Bradford on Avon and Westbury Air Quality Management Areas (both kerbside sites). All data presented in this report has been ratified and adjusted as appropriate according to current guidance (see Section 6.2.2 below). Table 32 provides the NO2,

PM10 and SO2 concentrations from both the Bradford on Avon and Westbury continuous analysers for 2006, 2007 and 2008. The Westbury analyser discontinued

Wiltshire Council – Updating and Screening Assessment 2009

monitoring PM10 and SO2 after 2006 due to very low concentrations as illustrated.

There is a triplicate NO2 diffusion tube study at the Bradford on Avon continuous analyser. The 2006, 2007 and 2008 precision and accuracy analysis of the data for this study is presented in Figure 3, Figure 4 and Figure 5 respectively.

6.2.2 Wiltshire Automatic Analysers - Quality Assurance/Quality Control Automatic Calibration To ensure that the information obtained from the analysers is as accurate as possible and to quantify any instrument drifts a stringent QA/QC protocol is followed. The API M200A analyser is subjected to daily automatic calibration. This provides a daily check on the performance of the instrument. It should be noted that these results are not used for instrument scaling. The zero air is generated by passing ambient air through purafil charcoal scrubbers before it is passed into the reaction cell. The span gas is generated by an NO2 permeation tube containing pure liquid NO2. The permeation tube is enclosed in an oven, which is maintained at a constant temperature. The zero air is passed across the permeation tube at a constant flow rate. Provided the flow rate and temperature are kept constant, the amount of NO2 permeating from the tube into the air stream will be constant. The gas then produced then passes into the reaction cell and a span calibration response is determined. The data is collected as 1-hour averages. The data is down loaded from the analyser and then stored on a desktop computer. The analyser is subjected to daily automatic calibration. This provides a daily check on the performance of the instrument. In the API M100A analyser, zero air is generated by passing ambient air through a charcoal scrubber, before entering the reaction cell.

Wiltshire Council – Updating and Screening Assessment 2009

Manual Calibration Every two weeks manual calibration checks are carried. This allows the instrument drifts to be fully qualified and documented using traceable calibration gas standards and the results are used to scale data. At the time of the instrument calibration checks, instrument pre-calibration checks are made to ensure that the condition of the analyser, before the calibration check, is assessed and any faults attended to. The fortnightly calibration procedure requires a zero check on the analyser. This is achieved by a source of zero air being provided by passing ambient air through the charcoal scrubber before it enters the reaction cell. Once stability has been achieved (this is defined as a variation of less than 0.1ppb over a one minute period for the analyser) three readings are recorded from the instrument display after three ten second intervals. Next the calibration gas bottle is opened at a pressure of 30 psi. The analyser is allowed to stabilise for a minimum of ten minutes. Three consecutive readings are taken from the instrument display, allowing ten seconds between readings. The calibration gas is then isolated. By considering the previous calibration results and the results obtained from the calibration just performed, the success of the calibration procedure is determined. The zero value should not differ by more than ± 2ppb from the previous calibration. The span calibration should not differ by more than 5% from that obtained during the previous calibration. Additionally, the analyser sample inlet filter is changed when necessary.

Six Monthly Checks These checks are carried out by our analyser suppliers, Enviro Technology Ltd at the same time as they service the equipment. They ensure that the measurements from the analyser are representative and inter-comparable. The calibrations act as an independent audit of the system performance. Additionally, any site-specific problems that may have remained undetected will be fully quantified.

6.2.3 Summary of monitoring undertaken – Diffusion Tube The nitrogen dioxide diffusion tubes are 20% TEA in water supplied and analysed by Bristol Scientific Services. The tubes at all 15 locations through out the West Wiltshire area have a monthly exposure period. There is a co-location study at the Bradford on Avon monitoring site. The co-location data is reviewed annually to determine if the local or national bias adjustment factor is more appropriate (based on the Technical Guidance LAQM.TG(09)). The follow bias adjustment factors have been applied to the data presented in this report:

Wiltshire Council – Updating and Screening Assessment 2009

• 2006 - 0.90 (based on 5 studies in the National Bias Adjustment Database v05/09 – the local co-location study had 4 months of questionable data in 2006) • 2007 - 0.77 (based on 5 studies in the National Bias Adjustment Database v05/09 – the local co-location study had 3 months of questionable data in 2007) • 2008 - 0.73 (based on local co-location study which had excellent data capture and diffusion tube precision in 2008 – National Bias Adjustment Factor Database reported a factor of 0.87 based on four studies)

All of the 2008 diffusion tube data has been annualised as required according to the guidance in LAQM.TG(09). Table 33 below provides site description information for all the monitoring sites in 2008. Table 34, Table 35 and Table 36 provide the diffusion tube data for 2006, 2007 and 2008 respectively. Maps of the West Wiltshire monitoring sites can be found in Appendix 4. Bristol Scientific Services participate in the WASP Scheme and have performed ‘good’ in January 2008 – January 2009 report published on the LA Support Helpdesk Website.

6.2.4 Comparison of monitoring results with the Air Quality Objectives – West Wiltshire

Continuous monitoring: Concentrations of NO2 reported in the continuous monitoring studies undertaken in Bradford on Avon and Westbury in 2008 are below the annual mean and short term air quality objectives for NO2.

Nitrogen Dioxide Diffusion Tubes: Two diffusion tube sites exceeded the NO2 annual mean objective in 2008. Both of these sites are within the existing AQMAs. These sites were: • 90 Warminster Road, Westbury (additionally Haynes Road and 76 Warminster Road were just below the annual mean objective) • Masons Lane, Bradford on Avon

Measured concentrations of NO2 in 2008 indicate exceedences of the annual mean air quality objective at two locations. The monitoring data for 2008 indicates that the AQMAs are still justified. No further work is required in relation to this section.

6.3 Screening of Sources of Emissions for West Wiltshire The following tables (Table 37, Table 38, Table 39, Table 40 and Table 41) summarise the screening of potential sources of emissions in the West Wiltshire area following the criteria set out in LAQM.TG(09). For further information on the specific screening criteria please see Chapter 2 of this document and Chapter 5 of LAQM.TG(09). Where necessary additional supporting evidence has been provided to highlight how conclusions have been established. Those boxes shaded in green indicate that no further work is required (i.e. a Detailed Assessment is not required), conversely, those boxes shaded in yellow indicate that further work is required (i.e. a Detailed Assessment is required).
