Executive Summary

South Gloucestershire Council have undertaken this Updating and Screening Assessment in fulfilment of Part IV of the Environment Act 1995 which requires local authorities to review and assess air quality within their administrative area. This Updating and Screening Assessment (Round 4) updates all monitoring data since the last Updating and Screening Assessment (undertaken in 2006) and screens for various potential sources of pollution with the Local Authority’s administrative area in accordance with the Local Air Quality Management Technical Guidance 2009 (LAQM.TG(09)). South Gloucestershire Council are currently in the process of declaring three Air Quality Management Areas, which are due to be declared in April 2010.

This Updating and Screening Assessment has concluded the following: • Assessment of Monitoring Data: Following the screening criteria in LAQM.TG(09), there are no exceedences of any of the pollutants of concern within South Gloucestershire. However there are three areas outside of the proposed AQMAs that are close to the annual mean nitrogen dioxide objective. • Assessment of Sources: Following the screening criteria in LAQM.TG(09), a

Detailed Assessment will be required for NO2 for moving locomotives at Winterbourne, Patchway, and . There are no other sources (transport, other transport, industrial, commercial/domestic and fugitive) of concern within South Gloucestershire.

South Gloucestershire Council will initiate a Detailed Assessment in respect of this newly identified source as soon as possible with a view to submitting the report to Defra by April 2011. South Gloucestershire Council should also continue current monitoring and report the results to Defra in a Review and Assessment Progress Report by the end of April 2010.

South Gloucestershire Council - England Updating and Screening Assessment

1 Introduction 1.1 Description of Local Authority Area

South Gloucestershire lies to the north and east of the city of Bristol with the forming the western boundary. The area covers approximately 49,700 hectares and is a diverse mix of urban and rural areas, including major residential, industrial and commercial developments. The road network within the district contains the major junction of the M4 & M5 motorways. Main line inter city passenger rail services are available from Bristol Parkway Station in Stoke Gifford. The 2008 mid-year population estimate for South Gloucestershire is 257,700, living in approximately 104,000 households. 60% of the population live in the built-up areas immediately adjoining Bristol, namely Filton, Patchway, Bradley Stoke, Kingswood, Downend, Staple Hill and Hanham; 19% live in the towns of Yate, Chipping Sodbury and Thornbury and the remaining 20% live in the more rural areas of South Gloucestershire. The population has grown by over 20% in the past 20 years, making it one of the fastest growing areas in the country and the population is projected to rise to 267,200 by 2011. The extensive urban areas around the northern fringe of Bristol have experienced significant growth over the past 20 years. More than 30,000 jobs and 18,000 homes have been created since 1991, and significant growth is expected to continue. Over the longer term, the Regional Spatial Strategy proposes that an additional 30,800 homes should be built in South Gloucestershire by 2026. This will increase the proportion of housing by nearly 30%, meaning that managing future development is a key challenge. The area has well-established manufacturing industries, such as aerospace and has attracted a number of high technology companies and national employers. There are high levels of car ownership and traffic congestion is a major problem around Bristol, linked to significant volumes of commuting traffic. This raises challenges in terms of the infrastructure needed to sustain further growth, such as maintaining economic prosperity, protecting the environment and addressing transport issues.

1.2 Purpose of Report

This report fulfils the requirements of the Local Air Quality Management 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.

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 1.1. 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).

South Gloucestershire Council’s Round 3 Updating and Screening Assessment was completed in May 2006 and was accepted for all pollutants. The report also showed compliance with the 2004 PM10 objectives at Yate, concluding that a Detailed Assessment previously identified in the 2003 and 2004 Progress Reports was no longer required. The subsequent Progress Report was completed in May 2007 and was approved by Defra. The report identified potential exceedences of the annual mean objective for nitrogen dioxide at one location; the crossroads of Broad Street (A4175), High Street (B4465), Victoria Street and Soundwell Road (A4017) in Staple Hill. Two additional locations were identified as approaching the NO2 annual mean objective; at the Cribbs Causeway M5 roundabout (Junction 17) and along Regent Street (A420), Kingswood.

The Progress Report concluded that it was necessary (or prudent where locations were approaching the objective), to proceed with a Detailed Assessment in relation to nitrogen dioxide in the following areas: • Staple Hill – at the Broad Street (A4175), High Street (B4465), Victoria Street and Soundwell Road (A4017) crossroads • Kingswood – along Regent Street (A420) • Cribbs Causeway – at the M5 Roundabout (Junction 17) The Detailed Assessment of these three areas commenced in April 2007 and was completed in September 2008. The report concluded that Air Quality Management Areas (AQMAs) should be declared at the locations identified above. Maps of the proposed AQMAs may be found in Appendix A. Consultation on the proposed AQMAs was undertaken and the resulting recommendations on the extent of each of the AQMAs have been made to Council. The formal declaration of the AQMAs is anticipated in April 2010.

2 New Monitoring Data 2.1 Summary of Monitoring Undertaken

2.1.1 Automatic Monitoring Sites

South Gloucestershire Council operate ten automatic monitors at seven sites:

• three API Model 200A Chemiluminescent Analysers (NO2),

• two ET BAM 1020 Beta-Attenuated Mass Monitors (unheated) (PM10),

• one R&P TEOM series 1400a (PM10),

• one API Model 400a UV Absorption Analyser (O3), and • three Millipore Volume Samplers (Cd, Cu, Zn, Pb).

An API Model 300 Infra Red Absorption Analyser (CO) located at Kingswood was decommissioned in 2007 as long-term monitoring had demonstrated that concentrations were well below the objective. South Gloucestershire Council also monitor background gamma radiation at the Council Offices in Thornbury however, as radiation does not fall within the remit of Local Air Quality Management, these results are not reported here. The 2008 BAM data have been corrected for gradient (divided by 1.21) and the 2008 TEOM data have been corrected using the VCM tool1. The 2006 and 2007 TEOM data have been multiplied by 1.3 as per LAQM.TG(09). Maps of the continuous monitoring sites, Millipore monitoring sites and diffusion tube monitoring sites exceeding or approaching the nitrogen dioxide annual mean objective are available in Appendix A. QA/QC data for the automatic monitors are in Appendix B. Table 3, below, provides details of the automatic monitoring sites.

2.1.2 Non-Automatic Monitoring

South Gloucestershire Council maintain 86 nitrogen dioxide (NO2) and 26 benzene (BTX) diffusion tube monitoring sites across the district. Table 4 shows details of these monitoring sites. The diffusion tubes are supplied and analysed by Bristol Scientific Services using the 20% TEA in water preparation method. Bristol Scientific Services adopted the harmonised method (50% TEA in water) for tube preparation and analysis from July 2008. South Gloucestershire Council operate a collocation study with the chemiluminescent monitor at Yate. However, the national bias adjustment factor was applied due to theft of tubes in 2006 and low continuous monitoring data capture in 2007. The national bias adjustment factor was therefore used for consistency in 2008. Full QA/QC data are presented in Appendix B.

2.2 Comparison of Monitoring Results with AQ Objectives

2.2.1 Nitrogen Dioxide

Automatic Monitoring Data

Nitrogen dioxide continuous monitoring data for 2006, 2007 and 2008 are presented in Table 5. There have been no exceedences of the annual mean or the hourly mean objective at any of the sites over these three years. Data capture for all sites was >90% in 2008, and where data capture was <90% in 2006 and 2007 percentile values are provided.

Diffusion Tube Monitoring Data

The results from each of the 86 nitrogen dioxide diffusion tube sites for 2008 are presented in Table 6 and the exceedences and borderline exceedences are summarised in Table 7. Results from 2006, 2007 and 2008 are provided for comparison in Table 8. All results are bias adjusted using the national bias adjustment factors for each year (Appendix B). Data capture for all sites in 2008 was >75%, except site 56, Barley Close Primary School, Mangotsfield (42%), however concentrations at this site were well below the objective so were not annualised. There were 26 diffusion tubes with measured exceedences of the nitrogen dioxide annual mean objective in 2008 and ten sites within 10% of the objective (i.e. >36 μg/m3). Three of these sites are not representative of relevant exposure so have been discounted. These sites are: • Site 8 – Filton - Gloucester Road North, St Peters Church; • Site 15 – Cribbs Causeway - Merlin Road; • Site 70 – Kingswood - Two Mile Hill Road, Job Centre Plus façade.

April 2010 Produced with the assistance of AQMRC, UWE, Bristol 15 South Gloucestershire Council - England Updating and Screening Assessment

Where necessary, measured exceedences have been adjusted to the façade of the nearest relevant receptor using the ‘Nitrogen Dioxide Fall off with Distance’ calculator (one of the LAQM Tools available on the Air Quality Archive website2) (Table 19, Appendix B). This revealed 11 exceedences and six borderline exceedences at the façades of relevant receptors, all of which are within proposed NO2 AQMAs. A further four borderline exceedences have been identified at relevant receptors where the monitoring sites are not included in proposed AQMAs. These sites are: • Site 10, Filton – 152 Gloucester Road North (38.2 μg/m3) • Site 33, Cribbs Causeway – M5 roundabout (39.1 μg/m3) • Site 35, Bradley Stoke – Woodlands Lane (38.0 μg/m3) • Site 48, Aztec West roundabout (38.1 μg/m3) Site 33 relates to the single residential property within the proposed Cribbs Causeway AQMA and therefore does not represent potential new exposure. Although nitrogen dioxide concentrations at these sites in 2008 are slightly higher than in the previous two years (a trend observed at most sites), concentrations have been consistently elevated and therefore sites 10, 35 and 48 should be observed with caution with regard to any planning or transport developments that may affect future nitrogen dioxide concentrations. It would also be advisable to relocate diffusion tubes at sites 8, 15, 35, 47, 48, 52, 64 and 70 to the façades of relevant receptor sites if possible.

2.2.5 Other pollutants monitored

South Gloucestershire Council monitor ozone, lead, cadmium, zinc and copper. These results are presented in summary below and in full in Appendix C. South Gloucestershire also monitor background gamma radiation at the Council Offices in Thornbury however, as radiation does not fall within the remit of Local Air Quality Management, these results are not reported here. South Gloucestershire Council do not monitor 1,3 butadiene. Carbon monoxide monitoring ceased in 2007. 2006 carbon monoxide data was reported in the 2007 Progress Report, and is not therefore reported here.

Ozone

Ozone is a regional and transboundary pollutant and does not have a locally applicable air quality objective. The health-based objective for ozone as specified in the national Air Quality Strategy is 100 μg/m3, measured as an 8-hour mean, not to be exceeded more than ten times per year. Ozone is monitored in South Gloucestershire and data from the continuous monitor for 2006, 2007 and 2008 are presented in Table 11. The 8-hour objective for ozone was exceeded in 2006 with 20 exceedences (against a maximum allowable of 10); however in 2007 and 2008, there were no exceedences of this objective. Data from the 2nd & 3rd quarters are reported as this is when ozone concentrations are likely to be highest.

3 Road Traffic Sources 3.1 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 element of the Updating and Screening Assessment only considers NO2. Hanham High Street, although not strictly a narrow street, has relevant exposure within 2 m of the kerb. There are no traffic data available for this site, however it is estimated that annual average daily traffic (AADT) is likely to be >10,000 vehicles per day (vpd) though average vehicle speed is not considered to be <15 mph. Monitoring at the nearby diffusion tube site (22) indicates that concentrations are likely to be below the annual mean objective, however South Gloucestershire Council propose to initiate a new monitoring site at this worst-case location. If monitoring data at this site indicates an exceedence of the objectives, then this data will be used in a Detailed Assessment to further examine the potential extent of any exceedence. South Gloucestershire Council have reviewed all other narrow congested streets in their area and determined that there are no sites of concern that meet the criteria detailed in Box 5.3 A2 LAQM.TG(09).

South Gloucestershire Council have identified narrow streets with residential properties close to the kerb with potential traffic flows >5,000 vehicles per day, and determined that there is no need to proceed to a Detailed Assessment at this stage.

3.2 Busy Streets Where People May Spend 1-hour or More Close to Traffic

The A38 Gloucester Road North at Northville was assessed as a potential busy street where people may spend 1-hour or more close to traffic. No monitoring data is available for this site. Traffic count data was obtained for A38 Gloucester Road North, north of The Wickets, (15,921) and A38 Gloucester Road North, south of Charborough Road (23,292); average traffic speed data was also obtained from the latter site. The data were inputted into DMRB (v 1.03c) to estimate the likelihood of exposure within 5 m of the kerb. No exceedences of the nitrogen dioxide objectives were predicted using the greater traffic count (Appendix D). The A38 Gloucester Road North mini-roundabout junction with Northville Road and Braemar Avenue should also be assessed as a potential busy junction. At present there are no traffic data available for the latter two roads. South Gloucestershire Council are advised to initiate short-term nitrogen dioxide diffusion tube monitoring at sites of relevant exposure at this junction to indicate the likelihood of an exceedence of the annual mean objective.

Consideration has been given to streets with many shops and/or outdoor cafes and bars where people may be expected to regularly spend one hour or more. This element of the Updating and Screening Assessment only considers NO2. South Gloucestershire Council have reviewed busy streets in their area and determined that although there may be relevant public exposure within 5 m of the kerb at some locations with traffic flows greater than 10,000 vpd, DMRB has indicated that there are no likely exceedences of the nitrogen dioxide objectives. There are no other sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.3 A.2 LAQM.TG(09).

South Gloucestershire Council have identified busy streets where people may spend one hour or more close to traffic, but can confirm that there is no need to proceed to a Detailed Assessment.

3.3 Roads with a High Flow of Buses and/or HGVs.

The A403 Severn Road, Aust to Avonmouth, was assessed as a road with a high flow of HGVs. The AADT for this road is 9,426 with 26% HGVs. There is relevant exposure within 10 m of the kerb, however the volume of HGVs is slightly less than the criteria (2,500 vpd). The road was assessed with DMRB using the nearest receptor to the road. No exceedences of the nitrogen dioxide annual mean objective and fewer than three exceedences (from a permitted 35) of the PM10 24-hour mean were predicted (Appendix D). 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 Heavy Goods Vehicles (HGVs). This element of the Updating and Screening Assessment considers both NO2 and PM10. South Gloucestershire Council have reviewed roads in their area and determined that there are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.3 A.3 LAQM.TG(09).

South Gloucestershire Council confirms that there are no new/newly identified roads with high flows of buses/HDVs.

3.4 Junctions

The junction of Soundwell Road A4017/ Downend Road/ Syston Way was identified as a busy junction with residential exposure within 5 m of the kerb. The nearest available traffic data is from Soundwell Road, north of Lansdown Road, with 13,829 AADT, but this does not take into consideration traffic from Downend Road and Syston Way. In addition no traffic speed or vehicle split data are available for this site. DMRB was used (with estimated traffic speed and vehicle split) to estimate whether exceedences of the objectives were likely. No exceedences of the nitrogen dioxide annual mean objective and fewer than two exceedences (out of a permitted

35) of the PM10 24-hour mean were predicted (Appendix D). It is recommended that

April 2010 Produced with the assistance of AQMRC, UWE, Bristol 29 South Gloucestershire Council - England Updating and Screening Assessment to properly assess exposure at this junction short-term nitrogen dioxide diffusion tube monitoring should be initiated at relevant receptor sites. The junction of Filton Avenue with Northville Road/ Ninth Avenue was identified as a busy junction with residential exposure with 10 m of the kerb. Two traffic counts are available for this junction, both on Filton Avenue, one north of the junction (12,792 AADT) and one to the south (12,974 AADT); Both sites also recorded traffic speed, though no data is available on traffic split. No data is available for either of the other two links, i.e. Northville Road or Ninth Avenue. DMRB was used to asses whether there was likely exposure at properties close to the kerb on Filton Avenue north and south separately. There were no exceedences of either the nitrogen dioxide or PM10 objectives at either site (Appendix D). It is recommended that to fully assess exposure at this junction, short-term nitrogen dioxide diffusion tube monitoring should be initiated at relevant receptor sites. The B4056 Southmead Road/ A38 Gloucester Road North/ A4174 Station Road roundabout was identified as a busy junction with relevant exposure within 10 m of the kerb. The nearest traffic data relevant to this site is from A38 Gloucester Road North, south of Charborough Road, though, as a B-road, Southmead Road is not likely to carry as much traffic. As receptors within similar distance to the kerb and with similar background concentrations were assessed as not being at risk of an exceedence of the objective on A38 Gloucester Road North, it is considered unlikely that receptors on B4056 Southmead Road would be exposed to higher concentrations. To fully assess the impact of the roundabout traffic on these receptors, it is recommended that short-term nitrogen dioxide diffusion tube monitoring should be initiated at relevant receptor sites. Relevant receptors were identified on Filton Avenue, south of the junction with A4174 Station Road. No receptors were identified within 10 m of the junction itself, but DMRB was calculated using the nearest relevant receptor on Filton Avenue using combined traffic flows from the junction and an estimated average speed of 40 kph.

No exceedences of the nitrogen dioxide annual mean or PM10 24-hourly mean objectives were predicted at the worst-case receptor (Appendix D). There are a number of other busy junctions around the A4174 ring road with potential for relevant exposure on adjacent link roads, e.g. Bromley Heath Road, Westerleigh Road and Deanery Road (Kingswood). No monitoring or traffic data are currently available for these sites, however having assessed the A4174 Station Road/Filton

Avenue junction using DMRB, it is considered that concentrations of NO2 and PM10 are not likely to lead to exceedences of the objectives at these similar locations. There are additional busy junctions around the A4174 ring road without potential for relevant exposure, e.g. Abbeywood MOD, Downend Junction (Wick Wick roundabout), Emersons Green (Rosary Roundabout), Pucklechurch (Dramway roundabout) and Station Road Link/Carsons Road (Siston Hill Roundabout). 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. South Gloucestershire Council has reviewed junctions in its area and has identified those described above as meeting some or all of the criteria requiring screening assessment. DMRB was used to assess the likely exposure of relevant receptors within the vicinities of these sites. The model does not indicate any exceedences of any of the objectives for nitrogen dioxide or PM10 and therefore a Detailed Assessment is not required. There are no other sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.3 A.4 LAQM.TG(09).

South Gloucestershire Council confirms that there are no new/newly identified busy junctions/busy roads that have not been assessed.

3.5 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. South Gloucestershire Council have reviewed new roads in their area and determined that there are no sites of concern that meet the criteria detailed in Box 5.3 A.5 LAQM.TG(09).

South Gloucestershire Council confirms that there are no new/proposed roads.

3.6 Roads with Significantly Changed Traffic Flows

This section of the Updating and Screening Assessment only considers those roads that have not been assessed in Sections 3.2 to 3.5 above. A significant increase can be considered as a 25% increase in traffic flow on any road with more than 10,000 vehicles per day. This element of the Updating and Screening Assessment considers both NO2 and PM10. South Gloucestershire Council have reviewed roads in their area and determined that there are no sites of concern that meet the criteria detailed in Box 5.3 A.6 LAQM.TG(09).

South Gloucestershire Council confirms that there are no new/newly identified roads with significantly changed traffic flows.

3.7 Bus and Coach Stations

This section considers bus stations or sections 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). Yate Bus Station has been assessed in previous Review and Assessment reports and does not have any relevant receptors within 10 m. South Gloucestershire Council have therefore reviewed bus and coach stations in their area and determined that there

April 2010 Produced with the assistance of AQMRC, UWE, Bristol 31 South Gloucestershire Council - England Updating and Screening Assessment are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.3 A.7 LAQM.TG(09).

South Gloucestershire Council confirms that there are no relevant bus stations in the Local Authority area.

4 Other Transport Sources 4.1 Airports

Consideration has been given to airports with more than 10 million passengers per annum (100,000 tonnes freight = 1mppa) and with relevant exposure within 1000 m of the airport boundary. This element of the Updating and Screening Assessment considers just NO2 (consideration of PM10 has been removed from the latest Technical Guidance). South Gloucestershire Council have reviewed airports in their area. Filton Airfield is not a commercial airport and does not have the throughput of freight or passengers to fulfil the criteria in this screening assessment. There are therefore no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.4 B.1 LAQM.TG(09).

South Gloucestershire Council confirms that there are no airports in the Local Authority area that meet the specified criteria.

4.2 Railways (Diesel and Steam Trains)

Stationary locomotives, diesel and coal-fired, can give rise to high levels of SO2 close to the point of emissions. Additionally, recent evidence suggests that lines with heavy traffic of moving locomotives may give rise to high levels of NO2 close to the track.

4.2.1 Stationary Trains

Railway Stations - Mainline Bristol Parkway Bristol Parkway is the main railway station in South Gloucestershire. The majority of passenger trains are “stop and go” with a few (approximately 12 per day) terminating at the station. The turnaround time for terminating trains is less than 15 minutes for all but two trains, which are additional commuter trains and only run on weekdays. The criteria of three or more occasions a day when locomotives might idle for 15 minutes or more is therefore not met. In addition, the trains terminate on the platform furthest from any relevant exposure, with the nearest garden 60 m away. Bristol Parkway station does not therefore require a Detailed Assessment. Filton Abbeywood This is a commuter station where trains “stop and go” so idling time is less than15 minutes. Therefore, there is no requirement for a Detailed Assessment at this location.

April 2010 Produced with the assistance of AQMRC, UWE, Bristol 33 South Gloucestershire Council - England Updating and Screening Assessment

Patchway Patchway is also a commuter station, though fewer trains call at this station than at Filton Abbeywood. Trains are “stop and go” so idling time is less than 15 minutes There is no relevant exposure within 15 m at Patchway station. Therefore, there is no requirement for a Detailed Assessment at this location. Pilning Pilning is a rural station with currently only two trains calling at the station per week. The trains are “stop and go” so idling time is less than 15 minutes. There is no relevant exposure within 15 m at Pilning station. Therefore, there is no requirement for a Detailed Assessment at this location. Severn Beach Severn Beach is the final station on this line but turnaround times are within 2-3 minutes. There is relevant exposure within 15 m (5 houses & additional 12 gardens) but there is no evidence that trains are idling for more than 15 minutes. Therefore a Detailed Assessment is not required at this site. Yate Yate is a commuter station with slightly fewer trains calling than at Filton Abbeywood. There is relevant exposure within 15 m (single property) but the trains are “stop and go” so idle for less than 15 minutes. Therefore, there is no requirement for a Detailed Assessment at this location.

Freight Loops/Sidings Bristol Parkway Freight loops adjoin the station but are closer to residential properties than the mainline tracks & station. There is evidence that trains are idling for more than 15 minutes on the freight lines. Figure 16 shows a map of the 15 m buffer from the sidings at Bristol Parkway along with potential relevant receptors (shaded grey). The 15 m buffer zone picks up the corner of a block of flats, Terris Court, Church Rd, Stoke Gifford, which is likely to have been built since the mainline railways were last assessed. However, only the corner of the building and a strip along the edge of the garden are contained within the 15 m buffer zone. The garden is communal and it is questionable whether there is potential for “regular outdoor exposure” as there is no permanent outside seating area or patio/decked area. Therefore as exposure is unlikely, a Detailed Assessment is not considered necessary for SO2 for this site. Charfield Figure 17 shows a map of the 15 m buffer from the railway at Charfield, including potential relevant exposure (shaded grey). There is relevant exposure within 15 m of the track at Charfield covering the bottom halves of gardens to 15 properties in Longs View, Charfield. It is not known whether trains idle here for 15 minutes or more. Further investigation with Network Rail is recommended to determine whether this site requires closer examination.

Chipping Sodbury Figure 18 shows a map of the 15 m buffer from the railway at Chipping Sodbury, including potential relevant exposure (shaded grey). There is relevant exposure within 15 m which includes three houses. It is not known whether trains idle here for 15 minutes or more. Further investigation with Network Rail is recommended to determine whether this site requires closer examination. Pilning There is no relevant exposure within 15 m of the track at Pilning, therefore a Detailed

Assessment for SO2 is not required at this site. Filton Airfield There is no relevant exposure within 15 m of the track at Filton Airfield, therefore a

Detailed Assessment for SO2 is not required at this site.

Steam/ Heritage Diesel , Bitton The Avon Valley Railway was previously assessed and screened in the 2006 Updating and Screening Assessment. However activity on this line has increased from around 75 days a year to 133 days per year, based on their proposed calendar for 20103. Figure 19 shows a map of the 15 m buffer from the railway at Bitton including potential relevant exposure (shaded grey). There is one house and two additional gardens within 15 m of the railway lines at Bitton station. The worst case scenario regarding idling times that can be ascertained from the timetables (Timetable A) is on the return to Bitton station from Avon Riverside. Here the trains are stationary for 15 minutes arriving on the hour (e.g. 12.00) before departing again for Oldland (e.g. 12.15). However, when the train is heading in this direction, any idling would occur at the end of the platform furthest away from the houses, approximately 57 m away from the nearest property and more than 20 m from the nearest garden. A Detailed

Assessment for SO2 for this location is therefore, not required. Consideration has been given to locations where locomotives, diesel or coal-fired, are regularly stationary for periods of 15 minutes or more and where relevant exposure exists. This element of the Updating and Screening Assessment only considers SO2. South Gloucestershire Council have reviewed stationary trains in their area and determined that although there are locations where trains are likely to be stationary for 15 minutes or more, there is no relevant public exposure; alternatively where there is relevant exposure, there is no evidence of idling trains at these locations. Therefore there are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.4 B.2 LAQM.TG(09).

South Gloucestershire Council confirms that there are no locations where diesel or steam trains are regularly stationary for periods of 15 minutes or more, with potential for relevant exposure within 15 m.

4.2.2 Moving Trains Consideration has been given to sections of tracks with large numbers of moving 3 diesel locomotives, with background NO2 concentrations greater than 25 μg/m and relevant exposure with 30 m of the edge of the tracks. This element of the Updating and Screening Assessment considers just NO2. South Gloucestershire Council have been identified in the supplementary ‘Guidance on Assessing Emissions from Railway Locomotives’, issued on the Review and Assessment website4, as having rail lines likely to meet the criteria above. Table 5.1 in LAQM.TG(09) defines these rail lines as between Bristol Temple Meads and Bristol Parkway and also between Paddington and Swansea. Properties have been identified using GIS in Stoke Gifford, Patchway, Little Stoke and Winterbourne that are within 30 m of the mainline track and have background 3 concentrations of NO2 >25 μg/m . The maps showing these properties (depicted with red dots) are available in Appendix A (Figure 20-Figure 22). South Gloucestershire Council have reviewed moving trains in their area and identified that a Detailed Assessment for nitrogen dioxide should be undertaken to investigate the likely exposure to emissions from moving locomotives at the properties identified above. No other sites of concern have been identified that meet the criteria detailed in Box 5.4 B.2 LAQM.TG(09).

South Gloucestershire Council confirms that there are locations with a large number of movements of diesel locomotives, elevated background concentrations of nitrogen dioxide and potential long-term relevant exposure within 30 m of the track. South Gloucestershire Council propose to undertake a Detailed Assessment to investigate potential exposure of the nitrogen dioxide objectives at the sites identified.

4.3 Ports (Shipping)

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

Screening Assessment only considers SO2. There are no ports within South Gloucestershire so consequently, there are no sites of concern that meet the criteria detailed in Box 5.4 B.3 LAQM.TG(09).

South Gloucestershire Council confirms that there are no ports or shipping within the Local Authority area.

5 Industrial Sources 5.1 Industrial Installations

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. A list of Part A1, Part A2 and Part B Permitted Processes in South Gloucestershire is provided in Appendix E. Many of these sources have been 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 include SO2, NO2, PM10 and benzene.

5.1.1 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. The Severnside Energy Recovery Centre has been proposed in 2009, however as this is only at the proposal stage, this will be reported in the 2010 Progress Report. South Gloucestershire Council have therefore reviewed new or proposed industrial installations in their area and determined that there are no sites of concern that meet the criteria detailed in Box 5.5 C.1 LAQM.TG(09).

South Gloucestershire Council confirms that there are no new or proposed industrial installations for which planning approval has been granted within its area or nearby in a neighbouring authority.

5.1.2 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 has been introduced. South Gloucestershire Council have reviewed existing industrial installations in their area and determined that there are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.5 C.1 LAQM.TG(09).

South Gloucestershire Council confirms that there are no industrial installations with substantially increased emissions or new relevant exposure in their vicinity within its area or nearby in a neighbouring authority.

5.1.3 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. South Gloucestershire Council have reviewed new or significantly changed industrial installations in their area and determined that there are no sites of concern that meet the criteria detailed in Box 5.5 C.1 LAQM.TG(09).

South Gloucestershire Council confirms that there are no new or proposed industrial installations for which planning approval has been granted within its area or nearby in a neighbouring authority.

5.2 Major Fuel (Petrol) Storage Depots

There is the potential for major fuel (petrol) depots to emit benzene and risk exceeding the 2010 objective. This element of the Updating and Screening Assessment considers benzene only. The fuel storage depot at Westerleigh has been assessed and monitored in previous Review and Assessment reports and is not deemed to be of concern. South Gloucestershire Council have therefore reviewed major fuel (petrol) storage depots in their area and determined that there are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.5 C.2 LAQM.TG(09).

South Gloucestershire Council confirms that there are no major fuel (petrol) storage depots within the Local Authority area that have not been previously assessed that meet the specified criteria.

5.3 Petrol Stations

Petrol stations combined with nearby busy roads may potentially emit sufficient benzene to risk exceeding the 2010 objective. Consideration must be given to all petrol stations with an annual throughput of more than 2000 m3 of petrol, with busy roads close by and relevant exposure within 10 m of the pumps. This element of the Updating and Screening Assessment considers benzene only. South Gloucestershire Council have reviewed petrol stations in their area and determined that there are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.5 C.3 LAQM.TG(09).

South Gloucestershire Council confirms that there are no petrol stations meeting the specified criteria.

Previous rounds of Review and Assessment have identified the potential for 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 100 m. This element of the Updating and Screening Assessment considers PM10 only. South Gloucestershire Council have reviewed poultry farms in their area and determined that there are no sites of concern that meet the criteria detailed in Box 5.5 C.4 LAQM.TG(09).

South Gloucestershire Council confirms that there are no poultry farms meeting the specified criteria.

6 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. 6.1 Biomass Combustion – Individual Installations

South Gloucestershire Council have identified two biomass boilers in operation in 2008 with thermal capacity between 50 kW and 20 MW. These are located at Filton Hill Primary School (two flues) and Stoke Lodge Primary School. Details of the boilers are provided in Table 16 and plans are available in Appendix F.

Emission factors for an advanced automatic wood pellet boiler were taken from Table A2.20 in LAQM.TG(09) and used to calculate maximum emissions rates for each stack based on their ‘Duty’ capacity (Table 17).

The Review and Assessment website states that: “If the actual stack above ground height is less than 2.5 times the height of the building to which it is attached or any other building within a distance of 5 times the stack height above the ground then it will be necessary to calculate an effective stack height following the calculation given in box 5.6 of LAQM.TG(09). If the stack height is more than 2.5 times the building

40 Produced with the assistance of AQMRC, UWE, Bristol April 2010 South Gloucestershire Council - England Updating and Screening Assessment height, then the effective stack height is equal to the actual height of the stack above the ground.”5 Both stacks are less than 2.5 times the height of the tallest building within 5 times the stack height, therefore the effective stack heights are calculated according to Box 5.6 in LAQM.TG(09) as follows: Filton Hill Primary: 1.66 x (6.38 – 5.23) = 2.66 m Stoke Lodge Primary: 1.66 x (9 – 6.5) = 4.15 m

Background concentrations of PM10 and NO2 were taken from the background maps on the LAQM Tools page of the Air Quality Archive website6. For each stack, background adjusted emissions rates were calculated for PM10, NO2 annual mean and NO2 hourly mean using the formulae provided on pp. 5-46 to 5-47 in LAQM.TG(09). These were then compared with the threshold emission rates from the nomograms in TG(09) figures 5.19, 5.20 and 5.21 respectively. Table 18 shows these comparisons for each stack; if the background adjusted emission rate is greater than or equal to the threshold emission rate, a Detailed Assessment will be required. None of the background adjusted emission rates calculated are greater than or equal to the threshold emission rates. Therefore a Detailed Assessment will not be required for biomass boilers.

Consideration has been given to large individual installations (50 kW to 20 MW in size) burning biomass. This element of the Updating and Screening Assessment considers PM10 and NO2. South Gloucestershire Council have reviewed individual biomass combustion installations in their area and determined that there are two sites that meet the criteria detailed in Box 5.8 D.1a LAQM.TG(09), neither of which, will require a Detailed Assessment.

South Gloucestershire Council has assessed biomass combustion plant, and concluded that there is no requirement to proceed to a Detailed Assessment.

6.2 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. Some of South Gloucestershire is covered by a Smoke Control Area7 which allows only approved fuels and appliances to be used. South Gloucestershire Council have reviewed the combined impacts of biomass combustion installations in their area and determined that the density of usage is low and there are no sites of concern that meet the criteria detailed in Box 5.8 D.1b LAQM.TG(09).

South Gloucestershire Council confirms that there are no areas of significant use of small biomass combustion units in the Local Authority area.

6.3 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. Some of South Gloucestershire is covered by a Smoke Control Area7. South Gloucestershire Council have reviewed domestic solid-fuel burning in their area and determined that there are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.8 D.2 LAQM.TG(09).

South Gloucestershire Council confirms that there are no areas of significant domestic fuel use in the Local Authority area.

7 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 sites. 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. Fugitive emissions from quarries and landfill sites have been previously assessed. Any complaints received are addressed under the procedures for permitted activities.

This element of the Updating and Screening Assessment considers PM10 only. South Gloucestershire Council have reviewed fugitive and uncontrolled sources in their area and determined that there are no sites of concern that have not been previously assessed that meet the criteria detailed in Box 5.10 E.1 LAQM.TG(09).

South Gloucestershire Council confirms that there are no potential sources of fugitive particulate matter emissions in the Local Authority area that have not been previously assessed.

8 Conclusions and Proposed Actions 8.1 Conclusions from New Monitoring Data

There were no exceedences of the nitrogen dioxide or PM10 objectives at any of the automatic monitoring sites. There were 26 diffusion tubes with measured exceedences of the nitrogen dioxide annual mean objective in 2008 and ten sites within 10% of the objective (i.e. >36 μg/m3). Having eliminated sites without relevant exposure and corrected kerbside sites to the façade of the nearest relevant receptor, 11 exceedences and six borderline exceedences were identified at relevant receptor sites. All of these exceedences are within proposed NO2 AQMAs. A further four borderline exceedences were identified at relevant receptors not included in the proposed AQMAs. These sites are: • Site 10 Filton – 152 Gloucester Road North (38.2 μg/m3) • Site 33 Cribbs Causeway – M5 roundabout (39.1 μg/m3) • Site 35 Bradley Stoke – Woodlands Lane (38.0 μg/m3) • Site 48 Aztec West roundabout (38.1 μg/m3) Site 33 relates to the single residential property within the proposed Cribbs Causeway AQMA and therefore does not represent potential new exposure. Although nitrogen dioxide concentrations at these sites in 2008 are slightly higher than in the previous two years (a trend observed at most sites), concentrations have been consistently elevated and therefore sites 10, 35 and 48 should be observed with caution with regard to any planning or transport developments that may affect future nitrogen dioxide concentrations. It would also be advisable to relocate diffusion tubes at sites 8, 15, 35, 47, 48, 52, 64 and 70 to the façades of relevant receptor sites if possible. No exceedences of the nitrogen dioxide objectives were identified outside the proposed AQMAs. Furthermore there were no exceedences of any of the other pollutants monitored for Review and Assessment (PM10, benzene, lead), therefore there is no requirement to proceed to a Detailed Assessment on the basis of monitoring data.

8.2 Conclusions from Assessment of Sources

This Updating and Screening Assessment has concluded the following: • This assessment has indicated that there are no Road Transport Sources of concern in South Gloucestershire, and therefore a Detailed Assessment is not required for this source.

44 Produced with the assistance of AQMRC, UWE, Bristol April 2010 South Gloucestershire Council - England Updating and Screening Assessment

• This assessment has indicated that a Detailed Assessment is required for NO2 for moving locomotives. There are no additional Other Transport Sources of concern in South Gloucestershire. • This assessment has indicated that there are no Industrial Sources of concern in South Gloucestershire, and therefore a Detailed Assessment is not required for this source. • This assessment has indicated that there are no other Commercial and Domestic Sources of concern in South Gloucestershire, and therefore a Detailed Assessment is not required for this source. • This assessment has indicated that there are no Fugitive or Uncontrolled Sources of concern in South Gloucestershire, and therefore a Detailed Assessment is not required for this source. South Gloucestershire Council have reviewed all of the potential sources as detailed in the Updating and Screening Assessment checklists in LAQM.TG(09) and have identified a requirement to proceed to a Detailed Assessment for NO2 at properties in Winterbourne, Patchway, Little Stoke and Stoke Gifford that are within 30 m of the 3 mainline track and have background concentrations of NO2 >25 μg/m . 8.3 Proposed Actions

South Gloucestershire Council will proceed to undertake a Detailed Assessment for

NO2 for moving trains at relevant properties in Winterbourne, Patchway, Little Stoke and Stoke Gifford. This Detailed Assessment will be submitted to Defra by April 2011. It is recommended that monitoring continue at sites of relevant exposure and that these results are reported in a Review and Assessment Progress Report together with updated information on new developments in the area to be submitted to Defra by the end of April 2010. It is also recommended that monitoring sites should wherever possible represent worst-case relevant exposure; monitoring sites in areas that are well below the air quality objectives or that do not represent relevant exposure should therefore be relocated accordingly.

Appendix B: QA/QC Data

Diffusion Tube Bias Adjustment Factors South Gloucestershire nitrogen dioxide diffusion tubes are supplied and analysed by Bristol City Council Scientific Services using the 20% TEA in water preparation method. The national bias adjustment spreadsheet is shown in Figure 23 depicting the factor used for 2008.

Figure 23: National bias adjustment factor spreadsheet for Bristol Scientific Services 2008

Factor from Local Co-location Studies (if available) The Precision and Accuracy spreadsheet (available from the LAQM Tools page of the Air Quality Archive) was used to compare the triplicate collocated diffusion tubes with the continuous monitor in Yate (Figure 24). The comparison revealed good precision and accuracy and a calculated local bias adjustment factor of 0.81.

Figure 24: Precision and Accuracy spreadsheet for Collocation Study at Yate

58 Produced with the assistance of AQMRC, UWE, Bristol April 2010 South Gloucestershire Council - England Updating and Screening Assessment

Discussion of Choice of Factor to Use The national bias adjustment factors were used due to diffusion tube theft in 2006 and automatic monitoring faults in 2007 resulting in poor data capture for these years. National factors used for 2006 and 2007 were 0.89 and 0.77 respectively. The national bias adjustment factor was used in 2008 for consistency. The national factor for 2008 (0.87) compares favourably with the locally calculated bias adjustment factor (0.81), and is actually slightly more conservative providing a precautionary approach to the calculation of the nitrogen dioxide diffusion tube annual mean concentrations.

PM Monitoring Adjustment All results have been adjusted to gravimetric equivalent. The 2008 BAM data have been corrected for gradient (divided by 1.21) and the 2008 TEOM data have been corrected using the VCM tool. The 2006 and 2007 TEOM data have been multiplied by 1.3 as per LAQM.TG(09).

Short-term to Long-term Data adjustment Data capture for all sites in 2008 was >75%, except site 56, Barley Close Primary School, Mangotsfield (42%), however concentrations at this site were well below the objective so were not annualised. Adjustment to facade There were 26 diffusion tubes with measured exceedences of the nitrogen dioxide annual mean objective in 2008 and ten sites within 10% of the objective (i.e. >36 μg/m3). Three of these sites (8, 15 and 70) are not representative of relevant exposure so have been discounted. Where necessary, measured exceedences have been adjusted to the façade of the nearest relevant receptor using the ‘Nitrogen Dioxide Fall off with Distance’ calculator (one of the LAQM Tools available on the Air Quality Archive website8). Rather than represent the calculations for each site, the data and results from the calculator have been provided in Table 19. The results from sites 47, 52 and 64 should be used with caution as the nearest receptor identified is more than 20 m further from the kerb than the monitor.

QA/QC of Automatic Monitoring The continuous monitoring network is operated and run by designated, trained officers. A programme of routine operational checks is in place for the network which includes: • Daily communications checks on lines, data transfer and analyser operation; • Daily checks of data quality; • Repairs of faulty equipment under arrangements with outside contractors; • Fortnightly site inspections to check equipment operational status, site security, detect equipment malfunction and to change inlet filters; • Four-weekly calibration checks on the analysers using nationally traceable standard gases by Bristol City Council (BCC) under contract to South Gloucestershire Council; • Planned six monthly servicing and re-calibration of the analysers by the equipment suppliers under contract to South Gloucestershire Council. Calibration Methods Calibration procedures are carried out four-weekly by a monitoring site engineer from BCC. The methodology for the calibration procedure, which includes a two point zero/span calibration check, is derived from the manufacturer’s instruction handbooks as follows: • Pre-calibration check - the site condition and status of the analyser is recorded prior to the zero/span check being conducted; • Zero check – the response of the analyser to the absence of the gas being monitored; • Span check – the response of the analyser to the presence of the gas of a known concentration; • Post calibration check - the site condition and status of the analyser on completion of all checks. Each analyser zero/span check is fully documented and records are kept by the engineer centrally. Calibration factors are then sent by the engineer on spreadsheets and are used in the data scaling and ratification process. The two point calibration is conducted on the NOx analysers using a zero air scrubber and nitric oxide (NO) calibration gas. The calibration gas is a UKAS certified reference NO mixture at a concentration of approximately 470 ppb, which is supplied by BOC and certified by the National Physics Laboratory (NPL). The contents of the portable scrubber used for zero air generation (hopcalite, activated charcoal, purafil and drierite) are changed when necessary or at least every six months.

Equipment Servicing and Maintenance All the NOx analysers and associated equipment are serviced and maintained on a planned schedule following manufacturers’ instructions. A six monthly full service and multi- point recalibration is carried out on the analysers under contract by Enviro Technology Services Ltd. The multi-point calibration involves the use of zero air, NO and NO2 calibration gases, which are again traceable to national standards, enabling the analyser data slope and offset factors to be reset. The contract also covers unscheduled site visits and repairs, for example in the event of equipment failure or receipt of spurious data, within a specified period of time to minimise data loss. Results of the servicing, calibrations and repairs are fully documented and stored centrally with basic site visit records also stored at the analyser locations. Data Processing, Validation and Ratification Raw data from the analysers is stored on data loggers and is downloaded to a PC via modem and telephone line from each site. All data is collected by Opsis EnviMan software loaded on the PC to which the data is downloaded. The Comvisioner and Reporter modules of the EnviMan software used allow full data manipulation and frequent checks on data measurements. The data outputs from the analysers are visually screened daily using EnviMan Comvisioner to check for obvious erroneous data and equipment faults. Periodically the data is then validated, which involves visual examination of the monitoring data to check for any spurious or unusual measurements, such as large spikes, ‘flat-lines’ and excessive negative data. The suspicious data is ‘flagged’ for more detailed investigation. The data is then ratified, which involves a critical review of all the information relating to the dataset and monitoring location to amend, verify or delete data, as appropriate. Any initial spurious data that was flagged is also re-examined during data ratification. The cause of the suspicious data can sometimes be identified, for example, it can be as a result of equipment failure or a power surge. Any spurious or doubtful data is removed. An original raw dataset is always kept in the data processing software enabling any amendments to the data to be traced. This also ensures that it is possible to re-examine the original collected data at a later date, if necessary. The data is then scaled against the four weekly and full six monthly calibration data. This ratified data is the final data presented in this report. The ratified data from the continuous NOx analyser at Yate is used to obtain a local bias adjustment factor (BAF) through comparison with results obtained for triplicate

NO2 diffusion tubes collocated at this analyser site.

QA/QC of diffusion tube monitoring Bristol City Council Scientific Services (BCCSS) carries out the placement and analysis of nitrogen dioxide diffusion tubes. While the laboratory is accredited by UKAS for a variety of tests in areas such as food, consumer safety, microbiology and asbestos, it does not currently have UKAS accreditation for the analysis of diffusion tubes. The current policy of the laboratory is to seek accreditation only when absolutely necessary. This is due not only to the expense of accreditation but also the lack of flexibility afforded. However, BCCSS participate in the Workplace Analysis Scheme for Proficiency (WASP) for nitrogen dioxide diffusion tubes. This involves the analysis of four diffusion tubes spiked with a known amount of sodium nitrite every four months and comparison of participating laboratories results. The results for Round 97 onwards in the WASP nitrogen dioxide proficiency test scheme are shown in Table 20.

BCCSS also analyse a solution supplied by AEA Technology each month as part of the QA/QC scheme that they run. In addition, BCCSS participate in field comparison exercises, again run by AEA Technology. In this scheme, triplicate diffusion tubes are collocated with a continuous analyser at Marylebone Road, London, which provides a reference value. The Field Comparison Summary Report for 2008 is shown in Figure 25.

Reference materials and equipment are obtained by BCCSS from suppliers who are approved to BS EN 9001. All reference materials are of at least analytical grade or equivalent. Standards are prepared using equipment that is all within BCCSS normal quality system. Diffusion tubes are supplied by Gradko and are “recycled” by Bristol Scientific Services. Each nitrogen dioxide diffusion tube is prepared by pipetting 30 )l (50 )l once the harmonised method was adopted for July 2008 exposure period) of a solution of 20% triethanolamine in water onto the metal grids in the end cap, then assembling the tube components. A fresh batch of tubes is prepared each month ready to dispatch in time for the required exposure date. A “blank” tube that has not been exposed is analysed with each batch of exposed tubes to determine if there has been any inadvertent contamination of the tubes. Data Ratification and Bias Adjustment The diffusion tube results are examined on a monthly basis to identify any spurious data and any suspect data is investigated further. Trends in monitored levels across

64 Produced with the assistance of AQMRC, UWE, Bristol April 2010 South Gloucestershire Council - England Updating and Screening Assessment the diffusion tube sites are compared to take into account seasonal factors, such as changing weather patterns and increased traffic flows, and to detect any local changes at the sites, such as road works. The monthly raw data is then averaged over the monitoring period to give a mean result. The monitoring period is usually a calendar year so the calculated average is therefore the annual mean. While diffusion tubes provide a simple, cost-effective way of monitoring a wide range of locations, the accuracy of the tubes can be variable depending on the laboratory preparation, handling and analysis. To overcome this, a Bias Adjustment Factor, is applied to the raw mean for the relevant monitoring period to ratify the dataset. This factor can be calculated from monitoring sites where triplicate diffusion tubes are co- located with a continuous NOx analyser by comparing results of the two measurement methods. Bias adjustment factors for the relevant year can either be obtained through calculating a local factor or using the factor derived from the national co-location study. To calculate the local bias adjustment factor, average monthly data for the triplicate diffusion tubes sited at the Yate continuous NOx analyser are compared with ratified data obtained for the same period from the analyser. In certain circumstances, for example where data capture at the continuous monitoring station is less than 90%, LAQM.TG(09) advises it is more appropriate to use the nationally derived bias adjustment factor (see Discussion of Choice of Factor to Use above). The national or combined collocation study is co-ordinated by Air Quality Consultants. They collate and assess data from authorities that co-locate diffusion tubes with continuous NOx analysers. By comparing collocation studies of several authorities that use the same laboratory, a robust combined bias adjustment factor can be calculated that is specific to the individual laboratory and their tube preparation method.
