Executive Summary

This Updating and Screening Assessment (USA) for 2015 is Phase 1 of the 6th round of the Air Quality Review and Assessment process.

The USA has been produced in accordance with guidance issued by Defra for reporting progress under the system of Local Air Quality Management. The role of the report is to chart the progress made by the Council in improving air quality since the publication of the 2012 USA.

The USA identifies all new pollutant sources, existing sources that have undergone relevant change, and any new or changed receptor locations relevant to those sources. Four diffusion tube monitoring locations are identified by the report where the annual mean NO2 objective was exceeded in 2014. Of these, three monitoring locations are not representative of relevant exposure and when the results are subjected to Defra’s NO2 fall-off with distance calculator, the predicted annual mean concentrations are all below 40μgm-3. The fourth location, adjacent one of the main routes from Hull into town centre, will benefit from the opening, in March 2015, of the new Beverley Southern Relief Road (BSSR), predicted to reduce through- traffic volume by around 60%. For all other monitoring locations, the report concludes there is no risk of any air quality objective being breached at any location of relevant exposure within the East Riding of Yorkshire.

In line with national policy, the Council will next produce an Annual Progress Report in 2016, which will include further assessment, supported by additional monitoring, of the four identified exceedences in order to determine whether there is a need to proceed to a Detailed Assessment.

1 Introduction 1.1 Description of Local Authority Area

The East Riding of Yorkshire is a large unitary authority with an area of 240,768 hectares and an estimated population of 334,179. Overall population density is very low, with only 1.4 people per hectare. Based on 2009 data from the Office of National Statistics (ONS), the largest town is Bridlington in the north east of the district, with 39,700 residents (although this is swelled dramatically by the influx of tourists during the summer months), the other major settlements being Beverley (32,200 – including Molescroft and Woodmansey); Goole (20,810) and Cottingham (17,650). Well over half the population reside in rural communities, many of which are small, scattered and geographically isolated. In total there are 333 settlements, ranging from large towns to small, isolated hamlets and farmsteads.

Traditionally the area has been associated with agriculture and 95% of the land is still in some form of agricultural use today. Tourism is of particular importance along the long coastal strip, whilst pockets of industry, including agricultural and aeronautical engineering, transport and distribution, glass manufacture, food and drinks manufacture and chemical production, are to be found inland in close proximity to the main conurbations. Natural gas refining is carried out in the far south east of the area whilst the inland port of Goole, served by vessels operating along the rivers and Ouse has long been associated with the handling of coal and other materials. Mineral production is still important to the region, with the chalk uplands of the Wolds having a long historical link with quarrying.

East Riding's rail network primarily comprises services along the Hull to Scarborough line (via Cottingham, Beverley, and Bridlington), Hull to Doncaster/Sheffield line (via Brough and Goole), Hull to Leeds line (via Brough and Selby) and Hull to line. Major Road links include the eastern section of the M62/A63 to Hull, the A164 (Humber Bridge to Beverley), the A1079 (Hull to York), the A614 (Goole to Bridlington) and the A165 (Hull to Bridlington).

Industrial sources of air pollution external to but capable of affecting air quality within the East Riding of Yorkshire include the Trent valley power stations to the south and the Aire valley power stations to the west.

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.

LAQM USA 2015 6 East Riding of Yorkshire Council

The objective of this Updating and Screening Assessment is to identify any matters that have changed which may lead to risk of an air quality objective being exceeded. A checklist approach and screening tools are used to identify significant new sources or changes and whether there is a need for a Detailed Assessment. The USA report should provide an update of any outstanding information requested previously in Review and Assessment reports.

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 g/m3 (milligrammes per cubic metre, mg/m3 for carbon monoxide) with the number of exceedences in each year that are permitted (where applicable).

LAQM USA 2015 7 East Riding of Yorkshire Council 1.4 Summary of Previous Review and Assessments

East Riding of Yorkshire Council published stage 1 of its first round of review and assessment in March 1999 and found that further assessment in the form of a 2nd and 3rd stage review was required in respect of nitrogen dioxide, sulphur dioxide and particulates (PM10). The combined stage 2 & 3 assessment, published in April 2001 concluded that all objectives for the three pollutants would be met by the relevant target dates

The second round of review and assessment commenced in 2003 with an Updating and Screening Assessment (USA), compiled in accordance with the policy1 and technical2 guidance issued by the Department for Environment, Food and Rural Affairs (Defra). The USA concluded that there was no risk of exceeding any of the Air Quality Objectives at any location of relevant exposure within the East Riding of Yorkshire. Progress Reports in 2004 and 2005 continued to support the conclusions of the USA.

Round three, consisting a further USA, produced in April 2006, and Progress Reports in 2007 and 2008, again concluded there was no risk of exceeding any Air Quality Objective at any location of relevant exposure within the East Riding of Yorkshire.

Round four, consisting the 2009 USA and Progress Reports in 2010 and 2011, was compiled in accordance with the revised policy3 and technical4 guidance.

One diffusion tube monitoring location identified an exceedence of the annual mean NO2 objective in 2010, before returning to compliance in 2011. The relatively large increase in the annual mean recorded in 2010 resulted from a combination of the effects of the exceptionally severe winter conditions, the introduction of a temporary one-way system in Beverley and from further hold-ups as a result of temporary traffic control measures affecting the interchange with the A1079 York Road. For all other locations of relevant exposure within the East Riding of Yorkshire, round four re- affirmed the previously reported position, identifying no need for the Council to proceed to a Detailed Assessment for any pollutant in relation to any relevant Air Quality Objective.

The 2012 USA confirmed the single 2010 exceedence had, as expected, returned to compliance in 2011. However, the report also identified exceedences at two further diffusion tube locations immediately adjacent the carriageway of the A614, the first on the outskirts of Goole and a second as it passes through Middleton-on-the-Wolds. As a result, additional monitoring was deployed along the route and it was concluded there was no need for the Council to proceed to a Detailed Assessment at that stage.

2 New Monitoring Data 2.1 Summary of Monitoring Undertaken

2.1.1 Automatic Monitoring Sites

East Riding of Yorkshire Council had until December 2012 operated three Automatic Air Quality Monitoring Stations (AAQMS) at kerbside locations across its area (see Figures 2.1 & 2.2). Efficiency measures saw the decommissioning of these AAQMS in favour of an enhanced roadside network of nitrogen dioxide diffusion tubes. Details of the exact locations of the former AAAQMS and the pollutants moniitored are given in Table 2.1.

2.1.2 Non-Automatic Monitoring Sites

A network of nitrogen dioxide diffusion tubes is deployed at kerbside locations across the Council’s area (see Table 2.2). Tubes supplied and analysed under contract by Environmental Scientifics Group (ESG Didcot) are prepared using the 50% TEA in Acetone method, in accordance with procedures set out in the Harmonisation Practical Guidance. The bias adjustment factor (0.81) derived from the National Diffusion Tube Bias Adjustment Factor Spreadsheet (Fig. 2.3) is applied to all annual mean diffusion tube data presented in this report.

2.2 Comparison of Monitoring Results with Air Quality Objectives

Monitoring data are reviewed and assessed in accordance with the guidance given in Box 5.2 of Chapter 5 of LAQM. TG(09).

2.2.1 Nitrogen Dioxide

Mapped Estimated Background Concentrations

Estimated annual mean background concentrations for NOX and NO2 for each 1km x 1km grid of the UK have been mapped from 2011 base-year maps and projections for each year up to 2030 can be accessed at: http://uk-air.defra.gov.uk/data/laqm-background-home

Automatic Monitoring Data

Until December 2012 the East Riding of Yorkshire Council operated a network of Automatic Air Quality Monitoring Stations at kerbside locations across its area (see Figures 2.1 & 2.2). Details of exact location and pollutants monitored are given in Table 2.1. The table shows the monitoring data for the last three years the stations were operational (the Preston site ceased operation on 29th February 2012)

Monitoring results for 2010, 2011 and 2012 are presented in table 2.3 and 2.4 below. The tables shows the monitoring data for the last three years the stations were operational (the Preston site ceased operation on 29th February 2012)

No annual mean NO2 concentration at any monitoring location exceeds 40gm-3.

No monitoring site has recorded more than 18 1-hour means above 200gm-3, or (where the period of valid data is less than 90% of a full year) has a 98th percentile of 1-hour concentrations exceeding 200gm-3.

A discernible increasing trend is evident in the annual mean NO2 concentration at the Beverley Kerbside monitoring site when viewed over the period 2001 to 2012 (figure 2.4). Trends for other automatic monitoring sites are not reported, since none remained in situ for 5 or more years prior to decommissioning.

Findings The nitrogen dioxide diffusion tube monitoring results shown in Table 2.5 indicate that the following locations exceeded the 40gm-3 annual mean objective concentration in 2014:

 No. 9 – Keldgate (No 163), Beverley (44gm-3)  No. 20 – Front Street, Middleton-on-the-Wolds; (44gm-3)  No.28 – A63 / Gibson Lane, North Welton; and (53gm-3)  No.72 – A63 West (Melton Grange), Melton (43gm-3)

Tubes No.28 and No.72 are located adjacent to the A63, the eastern extremity of the M62 motorway and the main route into Hull. Tube No.28 has shown a significant (13%) decrease between 2013 and 2014, with the annual mean NO2 concentration 3 3 decreasing from 61g/m to 53g/m . Tube No.72 has recorded an annual mean NO2 concentration increased by 9% from 39g/m3 to 43g/m3. Neither of these tube locations is representative of public exposure. When subjected to the Defra “NO2 fall- off with distance” calculator the predicted annual mean NO2 concentrations at the nearest, respective receptor locations for these tubes are both within the 40g/m3 objective (Fig’s 2.5 and 2.6). Monitoring continues at both locations and additional diffusion tubes have been deployed along this stretch of the route at varying distances from the kerb, the results to be reported and discussed in future reports.

This calculator allows you to predict the annual mean NO2 concentration for a location ("receptor") that is close to a monitoring site, but nearer or further the kerb than the monitor. The next sheet shows your results on a graph. Enter data into the yellow cells

Figure 2.6 Predicted annual mean NO2 Concentration (in g/m3) at the nearest receptor location to tube number 72

In 2013 and after 12 years of co-location with a (now decommissioned) reference method analyser at the junction of Admiral Walker Road and Keldgate in Beverley, Tube No 9 was relocated across the road (outside No.163 Keldgate). Table 2.5 3 shows the tube recorded an annual mean NO2 concentration of 44g/m for 2014, having previously recorded a 12-year average annual mean concentration of 30.5gm-3 prior to relocation. The Beverley Southern Relief Road (BSRR) was opened in March 2015. Proposals for the new road were originally reported in the 2004 Progress Report; it has been specifically designed to divert traffic away from Beverley town centre, with Keldgate predicted to benefit from an estimated 60% reduction. The addition of a proposed park and ride scheme, to be located on the outskirts of Beverley, will see further reductions in through-town traffic in coming years. Monitoring at this location will continue for the foreseeable future and the results published and discussed in future reports.

Tube No.20 has been deployed at its current location outside No.45 Front Street since 2012. Having recorded an exceedence (43g/m3) of the annual mean objective in 2011, it was relocated from its previous position (outside No.30 Front Street) in order to give a better representation of relevant exposure. This latest monitoring location is at the kerbside of the A614 as it passes through the village of Middleton–on-the-Wolds. This is the main route connecting the coastal resort of Bridlington with the M62 motorway and A1079 Hull to York trunk road. The tube 3 3 recorded an annual mean NO2 concentration of 44g/m in 2014 (41g/m in both 2012 and 2013). When subjected to the “fall-off with distance” calculator the predicted annual mean NO2 concentration at the façade of the nearest relevant receptor falls to 35g/m3 (Fig. 2.7)

1. LAQM USA 2015 47 East Riding of Yorkshire Council

Additional tubes have been deployed along this stretch of road since 2012 to characterise the situation in the village. Tubes No.53 and 54, located kerbside outside residential properties on Church Hill Road, have returned annual mean NO2 concentrations for 2104 of 39g/m3 and 31g/m3 respectively.

Diffusion tube monitoring continues in Middleton-on-the-Wolds; the results will be reported and discussed in the 2016 Progress Report.

Figure 2.7 Predicted annual mean NO2 Concentration (in g/m3) at the nearest receptor location to tube number 20.

Tube No.3 (Rawcliffe Road, Goole), having recorded an annual mean NO2 concentration of 41g/m3 in 2011, has, as predicted, returned to a level below the 40g/m3 objective, recording an annual mean concentration of 36g/m3 in both 2012 and 2013, and 34g/m3 in 2014. Monitoring still continues at this location adjacent the main traffic route into Goole town centre.

Trends in annual mean NO2 concentrations from kerbside diffusion tube monitors in- situ for at least 5 years are shown in figures 2.8 to 2.12.

2.2.2 PM10

Until December 2012 the East Riding of Yorkshire Council operated a network of Automatic Air Quality Monitoring Stations (AAQMS) at two kerbside locations in Beverley and one in the village of Preston, near Hull (see Figures 2.1 & 2.2).

© PM10 concentrations at each of these locations were measured using TEOM instruments and the data corrected using the Volatile Correction Model (VCM).

Monitoring results for the last four years of operation (2009, 2010, 2011 and 2012) prior to decommissioning are presented in tables 2.7 and 2.8 below. The Preston AAQMS ceased operation in February 2012, so results are presented to 2011 only.

-3 No monitored annual mean PM10 concentration exceeded 40gm .

No monitoring site has recorded more than 35 exceedences of the 50gm-3 24-hour mean, or has a 90thpercentile of 24-hour concentrations exceeding 50gm-3.

3 Road Traffic Sources

3.1 Narrow Congested Streets with Residential Properties Close to the Kerb

East Riding of Yorkshire Council confirms that there are no new/newly identified congested streets with a flow above 5,000 vehicles per day and residential properties close to the kerb, that have not been adequately considered in previous rounds of Review and Assessment.

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

East Riding of Yorkshire Council confirms that there are no new/newly identified busy streets where people may spend 1 hour or more close to traffic.

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

East Riding of Yorkshire Council confirms that there are no new/newly identified roads with high flows of buses/HDVs.

3.4 Junctions

In March 2015, the Beverley Southern Relief Road (BSRR) was brought into operational use. This new road, discussed in previous review and assessment reports since 2004, forms part of the Beverley Integrated Transport Plan (BITP) specifically designed to divert traffic away from Beverley town centre, with certain routes predicted to benefit from an estimated 60% reduction in traffic volumes. New roundabouts have been created at either end of the BSSR to connect it to the existing road network, and the existing Grovehill Road roundabout on the A1174 Hull Road has undergone extensive re-configuration in anticipation of the additional volume of traffic diverted away from town centre routes.

1. LAQM USA 2015 57 East Riding of Yorkshire Council

An Air Quality Assessment, prepared as part of the Environmental Impact Assessment (EIA) for the BSSR, concluded there will be no significant adverse impacts as a result of the new road scheme.

An existing network of nitrogen dioxide diffusion tubes has been strategically located in and around Beverley to assess the impact of this scheme and to compare NO2 concentrations before and after bringing the road into use. The monitoring results will be reported and discussed in future reports.

East Riding of Yorkshire Council has assessed new/newly identified junctions meeting the criteria in Section A.4 of Box 5.3 in TG(09), and concluded that it will not be necessary to proceed to a Detailed Assessment.

3.5 New Roads Constructed or Proposed Since the Last Round of Review and Assessment

In March 2015, the Beverley Southern Relief Road (BSRR) was brought into operational use. This new road, discussed in previous review and assessment reports since 2004, forms part of the Beverley Integrated Transport Plan (BITP) specifically designed to divert traffic away from Beverley town centre, with certain routes predicted to benefit from an estimated 60% reduction in traffic volumes. The addition of a proposed park and ride scheme, located on the outskirts of Beverley, will see further reductions in through-town traffic in coming years. An existing network of nitrogen dioxide diffusion tubes has been strategically located in and around Beverley to assess the impact of this work and to compare NO2 concentrations before and after bringing the road into use.

East Riding of Yorkshire Council confirms there are no other new roads or newly identified roads with significantly changed traffic flows in the Local Authority area since the last Updating and Screening Assessment.

Satisfactorily robust Air Quality Assessment has been undertaken for each of these proposed plants. In each case it has been concluded that the operation will not have a significant impact on local air quality and is unlikely to lead to an exceedence of any relevant air quality objective.

East Riding of Yorkshire Council has assessed the biomass combustion plant, and concluded that it will not be necessary to proceed to a Detailed Assessment.

1. LAQM USA 2015 65 East Riding of Yorkshire Council 6.2 Biomass Combustion – Combined Impacts

East Riding of Yorkshire is predominantly rural, with well over half the population residing in rural communities, many of which are small, scattered and geographically isolated. Consequently, population (and, hence, housing) density across much of the area is low and whilst some wood combustion takes place, domestic PM10 emissions do not meet the specified criteria.

Previous assessment has identified a low incidence of solid fuel combustion (including biomass) within the main urban population centres, the majority of residential and commercial premises being fuelled by gas.

6.3 Domestic Solid-Fuel Burning

East Riding of Yorkshire is predominantly rural, with well over half the population residing in rural communities, many of which are small, scattered and geographically isolated. Consequently, population (and, hence, housing) density across much of the area is low and domestic PM10 and SO2 emissions do not meet the specified criteria.

Previous rounds of review and assessment have identified a low incidence of solid fuel combustion within the main urban population centres, the majority of residential and commercial premises fuelled by gas. No significant change affecting any relevant 500m x 500m grid has since been identified.

East Riding of Yorkshire Council confirms that there are no areas of significant domestic fuel use in the Local Authority area.

1. LAQM USA 2015 66 East Riding of Yorkshire Council

7 Fugitive or Uncontrolled Sources

Previous rounds of review and assessment have considered PM10 emissions from fugitive and uncontrolled sources. No additional sources likely to give rise to significant dust emissions, or additional relevant exposure to any existing sources, have been subsequently identified.

East Riding of Yorkshire confirms that there are no potential sources of fugitive particulate matter emissions in the Local Authority area.

8 Conclusions and Proposed Actions 8.1 Conclusions from New Monitoring Data

Four diffusion tubes recorded bias-adjusted annual mean NO2 concentrations exceeding the 40µg/m3 air quality objective:

Tube No.9 (No.163 Keldgate, Beverley) - 44 µg/m3

Tube No.20 (No.30 Front Street, Middleton-on-the-Wolds) –44 µg/m3

Tube No.28 (A63/Gibson Lane North, Welton) –53 µg/m3

Tube No.72 (A63 West (Melton grange), Melton) –43 µg/m3

Tube No.9. After 12 years of co-location with a (now decommissioned) reference method analyser at the junction of Admiral Walker Road and Keldgate in Beverley, Tube No 9 was relocated across the road (No.163 Keldgate) in 2013. The tube 3 recorded an annual mean NO2 concentration of 44g/m for 2014, having previously recorded a 12-year average annual mean concentration of 30.5gm-3 prior to relocation. The Beverley Southern Relief Road (BSRR) was opened in March 2015. Proposals for the new road were originally reported in the 2004 Progress Report; it has been specifically designed to divert traffic away from Beverley town centre, with Keldgate predicted to benefit from an estimated 60% reduction. The addition of a proposed park and ride scheme, located on the outskirts of Beverley, will see further reductions in through-town traffic in coming years. Monitoring at this location will continue for the foreseeable future and the results published and discussed in future reports.

Tube No.20. Deployed at its current location outside No.45 Front Street since 2012. After having recorded an exceedence (43g/m3) of the annual mean objective in 2011, it was relocated from its previous position (outside No.30 Front Street) in order to give a better representation of relevant exposure. This latest monitoring location is at the kerbside of the A614 as it passes through the village of Middleton–on-the- Wolds. This is the main route connecting the coastal resort of Bridlington with the M62 motorway and A1079 Hull to York trunk road. The tube recorded an annual 3 3 mean NO2 concentration of 44g/m in 2014 (41g/m in both 2012 and 2013). When subjected to the “fall-off with distance” calculator the predicted annual mean NO2 concentration at the façade of the nearest relevant receptor falls to 35g/m3.

Additional tubes have been deployed along this stretch of road since 2012 to characterise the situation in the village. Tubes No.53 and No.54, located kerbside outside residential properties on Church Hill Road, have returned annual mean NO2 concentrations for 2104 of 39g/m3 and 31g/m3 respectively.

Diffusion tube monitoring continues in Middleton-on-the-Wolds; the results will be reported and discussed in the 2016 Progress Report.

1. LAQM USA 2015 68 East Riding of Yorkshire Council

Tubes No.28 and No.72 Located adjacent the A63, the eastern extremity of the M62 motorway and the main route into Hull. Tube No.28 has shown a significant (13%) decrease between 2013 and 2014, with the annual mean NO2 concentration decreasing from 61g/m3 to 53g/m3. However, Tube 72, has shown an annual 3 3 mean NO2 concentration increased by 9% from 39g/m to 43g/m . Neither of these tube locations is representative of public exposure. When subjected to the Defra “NO2 fall-off with distance” calculator the predicted annual mean NO2 concentrations at the nearest, receptor locations for these two tubes fall to 32g/m3 and 35g/m3 respectively.

Monitoring continues at both locations and additional diffusion tubes have been deployed along this stretch of the route at varying distances from the kerb, the results to be reported and discussed in future reports.

8.2 Conclusions from Assessment of Sources

The assessment of new or significantly changed sources has not identified the need to proceed to a Detailed Assessment for any prescribed pollutant. No potential exceedence of a relevant Air Quality Objective as a result of such sources is identified.

Satisfactorily robust air quality assessments have been submitted in relation to all new or proposed industrial sources identified, concluding that each is unlikely to lead to an exceedence of any Air Quality Objective.

No significant changes affecting other transport related sources or commercial, domestic or fugitive emissions have been identified by the assessment.

8.3 Proposed Actions

The Updating and Screening Assessment has not identified the need to proceed to a Detailed Assessment for any Pollutant in relation to any Air Quality Objective.

As reported in 8.1 above, additional diffusion tubes have been deployed along Front Street, Middleton-on-the-Wolds to better characterise any potential impact on annual mean NO2 concentrations at relevant receptor locations resulting from traffic flows along the A614. Assessment of the results to determine whether the recorded exceedences are representative of a sustained increase in NO2 concentration requiring the Council to proceed to a Detailed Assessment will be discussed in subsequent reports.

The Council’s next course of action will be to submit an Annual Progress Report in 2016.
