Executive Summary

This Progress Report has been produced in fulfilment of South Somerset District Councils responsibilities under Part IV of the Environment Act 1995 to annually review local air quality. This report is the second report of the fourth round of reports produced for Defra. The report summarises ongoing management of local air quality in South Somerset and describes changes within the district since the Updating Screening Assessment in 2009. All seven specified pollutants: carbon monoxide, benzene, 1,3-butadiene, lead, nitrogen dioxide, sulphur dioxide and airborne particles have been considered. Additionally concentrations of ozone in rural areas has been discussed. New monitoring data collected in 2009 continues to show that the concentrations of specified pollutants remain less than the objective values, with the exception of nitrogen dioxide within the Yeovil Air Quality Management Area. There is already an Air Quality Action Plan for nitrogen dioxide from traffic emissions in Yeovil, and so there is no requirement to proceed to detailed assessment for any pollutant within South Somerset. During 2009 the concentration of nitrogen dioxide within the Yeovil Air Quality Management Area was measured to be greater than the annual mean objective value in only one location on Ilchester Road. In 2008 four locations exceeded the nitrogen dioxide objective. The council and Somerset Highways continue to work on measures to reduce the impact of emissions from vehicles in Yeovil. The council minimises introducing new receptors within vulnerable areas, and encourages essential developments to be sympathetic to air quality by promoting modal shift. In 2010, the council held a carbon reduction day to encourage staff to reduce emissions and to promulgate low emissions technology. The Yeovil Air Quality Management Area will remain in order to help reinforce policies that help maintain and enhance air quality in Yeovil. Monitoring data collected during 2009 shows that air quality in South Somerset is being maintained and that a Detailed Assessment is not required for any specified pollutant within South Somerset. The next report will be a progress report in 2011.

Progress Report


1 Introduction Air quality is monitored by South Somerset District Council so that health impacts caused by poor air quality can be prevented from occurring. The monitoring of air quality by the council is also a statutory requirement under Part IV of the Environment Act 1995. The Fifth Report for the House of Commons Environmental Audit Committee which focuses on Air Quality concluded that the UK should be ashamed of it is poor air quality and the harm this causes 1. The air quality in South Somerset is mostly good due to its rural character and location on the western side of the United Kingdom, although at some locations in Yeovil the objective for nitrogen dioxide has been marginally exceeded due to road traffic emissions. To help manage air quality at these roadside locations, a town wide strategy was needed and so the whole of Yeovil rather than just these locations was declared an Air Quality Management Area. In addition to its statutory duties, South Somerset District Council also monitors airborne particulate matter, nitrogen dioxide, and low level ozone in a rural location to provide rural background data to Defra for its national monitoring programme (UK Automatic Urban and Rural Network AURN vide http://aurn.defra.gov.uk/)

1.1 Description of Local Authority Area

South Somerset covers a large and diverse area, extending some 64 miles from east to west with an area of 960 square kilometres: its location is shown in Figure 1.1. The estimated total population is 158,700 (Nomisweb. 2008). The population is mostly rural with almost 45% of the population living in settlements of fewer than 2500 people, with the two principle towns of Yeovil and Chard having more than 10,000 inhabitants each (41,000 and 12,000, respectively).

Progress Report

http://aurn.defra.gov.uk/


The district has a long history of manufacturing in the engineering and food-processing industries, with economic activity in manufacturing almost double the national average (20.8 compared to 10.2%, respectively). Although tourists drive through South Somerset on their way to the honey pots of Devon and Cornwall, tourism only accounts for 6.4% of employment in South Somerset. The opportunity to use of public transport is limited in rural villages and hamlets and so journeys are mostly made by private car: The 2001 census showed that only 2.4% of journeys to work were by public transport. Nationally 73% of households own at least one car, but in South Somerset this rises to 84%. The district is crossed east-west by the A303 and A30 and north-south by the A37 and A358. Three railway lines cross the district: Exeter to Waterloo, Exeter to Paddington and Bristol to Weymouth. Whilst Dorset and Wiltshire Councils have become unitary authorities, the county of Somerset has historically already had areas cleaved off (North Somerset, Bath and North East Somerset); the remaining councils have formed partnerships with other councils both within and outside Somerset. South Somerset has a shared boundary with East Devon District Council and the main transport routes of the A303 and A30 flow between the two districts. The councils already share a chief executive and a joint management structure is being formed. As with parts of Yeovil in South Somerset, the Exeter Road junction in Honiton in East Devon exceeded the nitrogen dioxide objective due to road traffic emissions. Each council continues to work on county strategies. Vehicular emissions remain the main cause for Air Quality Management Areas in Europe, and account for 90% of the Air Quality Management Areas in the UK. The propensity of nitrogen dioxide to exceed EU objectives where traffic is concentrated in urban areas has caused Defra to meet with local authorities in major conurbations to see if any UK solutions are effective. In smaller urban areas such as Yeovil, the measures identified in the Yeovil Action Plan (see Chapter 9) and reduced concentrations due to fleet improvement and better engines are considered to be adequate. The six neighbouring councils that share boundaries with South Somerset, shown in Figure 1.2, have not have any significant new or altered processes in their districts that may have an impact upon air quality in South Somerset. Since the last updating screening assessment in 2009, Mendip District Council and West Somerset District Council have continued to consider the impact of road traffic emissions of nitrogen dioxide in congested areas of its district.

Progress Report 10


Figure 1.2 South Somerset and Adjacent Councils

The potential sources of emissions of specified pollutants within the district are relatively few and larger processes that emit directly to air (cement works, waste oil burners, benzene from petrol stations, crematoria, etc) are regulated by South Somerset District Council through the Environmental Permitting Regulations. Installations that currently hold permits are listed in Table 1.1, next page.

The potential for many small unregulated sources occurring within small areas such as domestic coal, wood and biomass burning were considered in the 2009 Updating screening assessment.

1.2 Purpose of Progress Report

Progress Reports maintain continuity in the Local Air Quality Management process. They are produced in the intervening years between the three-yearly Updating and Screening Assessment reports. They are not intended to be as detailed as Updating and Screening Assessment Reports, or to require as much effort. However, if the Progress Report identifies the risk of that an Air Quality Objective may be exceeded, South Somerset District Council would undertake a Detailed Assessment immediately, and not wait until the next round of Review and Assessment. The only objective to be exceeded in South Somerset is the annual mean concentration of nitrogen dioxide - this location is already within a Air Quality management Area declared for the same source (traffic emissions), and so further detailed assessment is not required. South Somerset District Council continues to produce monthly Air Quality bulletins http://www.southsomerset.gov.uk/index.jsp?articleid=10475) and the data from our background site (along with other national sites) is emailed to any stakeholders that wish to receive the updates (http://www.airquality.co.uk/bulletin_reg.php). Previous Local Air Quality reports can be downloaded from the councils website (http://www.southsomerset.gov.uk/index.jsp?articleid=10474).

1.3 Air Quality Objectives

In England, the air quality objectives applicable to Local Air Quality Management are set out in the Air Quality (England) Regulations 2000 (SI 928), and the Air Quality (England) (Amendment) Regulations 2002 (SI 3043). The objectives are shown in Table 1.2, next page. Table 1.2 shows the objectives in units of microgrammes per cubic metre µg/m3 (for carbon monoxide the units used are milligrammes per cubic metre, mg/m3). This table includes the number of times the objective screening value can be exceeded in any given year before the objective value has not been achieved (where applicable).

1.4 Summary of Previous Review and Assessments

The 1995 Environment Act provides the timetable for the review and assessment process. The assessments are organised into three-year cycles known as ‘rounds’, with additional assessment and reporting being required if any air quality problems are suspected. This is the second report of Round 4: it updates the 2009 updating screening assessment with the results of monitoring and highlights any significant changes within the district that may have an impact upon air quality or those exposed. Every three years sources of emissions are reconsidered as part of the Updating Screening Assessment report, and in the interim 2 years any changes within the district are recorded. However, if major changes have occurred that are suspected of affecting the screening assessment in the air quality the Updating Screening Assessment, then a detailed assessment is started rather than waiting to assess the change when the next screening period is due. Previous reports include the following:

Round 1 • Stage 1 Review and Assessment 1999 • Stage 2 Review and Assessment 2000 • Stage 3 Review and Assessment 2001 • Stage 4 Review and Assessment 2002

Round 2 • Updating and Screening Assessment 2003 • Progress Report 2004 (including Yeovil Air Quality Management

Area Initial Action Plan) • Progress Report 2005

Round 3 • Updating and Screening Assessment 2006 • Progress Report 2007 • Progress Report 2008

Round 4

• Updating and Screening Assessment 2009 In 2002, the Stage 3 report recommended the declaration of an Air Quality Management Area in Yeovil as modelling indicated that the annual mean objective for nitrogen dioxide might be exceeded in 2005 unless action could be taken. In August 2002 the Yeovil Air Quality Management Area was declared and a Air Quality Action Plan produced in 2005. Yeovil’s Air Quality Management Area is due to emissions of nitrogen dioxide from road traffic. The whole town was declared, rather than only the areas near the A30 and A37 because a town wide action plan would be required to manage the local and through traffic2. 2 The whole town approach has many advantages and is increasingly seen as the apposite way of approaching Local Air Quality Management due to traffic emissions in many locations. The most recent whole town Air Quality Management Area being Coventry which was declared for NO2.

The 2004 Progress Report included an initial Air Quality Action Plan for the Yeovil and since then there have been 4 reports about the Yeovil Air Quality Management Area:

• Air Quality Action Plan 2005 • Yeovil Air Quality Management Area Progress Report 2007 • Yeovil Air Quality Management Area Progress Report 2008 • Yeovil Air Quality Management Area Progress Report 2009

Current data shows that the through traffic is still causing the annual mean objective for nitrogen dioxide to be exceeded on Ilchester Road (Yeo11). This location is within the Yeovil Air Quality Management Area and so further detailed assessment is not required. The Yeovil Air Quality Management Area is shown in Figure 1.4

2 New Monitoring Data 2.1 Summary of Monitoring Undertaken

Ambient particulate matter and nitrogen dioxide are measured in real time at Yeovil Hospital and monthly concentrations of nitrogen dioxide at various locations in Yeovil are assessed using diffusion tube gauges. All monitoring data collected indicates that the objectives have been achieved, with the exception of nitrogen dioxide at one roadside location. Quality Assurance and Quality Control is summarised in Appendix A.

2.2 Monitoring Locations

The automatic monitoring site is ideally located at Yeovil District Hospital to assess the impact of through traffic that is responsible for the emissions that caused the Air Quality Management Area to be declared. It is a similar distance from the through road to that of nearby houses and so whilst the actual location does not have relevant exposure per se it is an appropriate location to assess air quality. Figure 2.1 shows Yeovil with current monitoring locations. Photographs of locations are shown in Appendix E.

2.3 Non-Automatic Monitoring

South Somerset District Council uses a network of 21 nitrogen dioxide diffusion tube gauges to monitor nitrogen dioxide in the Yeovil Air Quality Management Area. Three of these nitrogen dioxide diffusion tube gauges are collocated alongside the above automatic analyser although in 2009 a local collocation factor could not be calculated due to poor data capture (see Appendix A). All locations monitored are within the Air Quality Management Area. The locations of these diffusion tubes (and the automatic analyser) are illustrated in Figure 2.1, above. Table 2.02 gives details of the non-automatic monitoring sites.

2.4 Comparison of Monitoring Results with Air Quality Objectives

2.5 Nitrogen Dioxide

There are two air quality objectives for nitrogen dioxide (NO2):

• Annual mean of 40 µg/m3

• 24-hour mean of 200 µg/m3 not to be exceeded on more than 18 times per year. All monitoring locations are within the Yeovil Air Quality Management Area that was declared to manage vehicular sources of nitrogen dioxide. Discussion of nitrogen dioxide monitoring data is divided into:

Automatic monitoring collecting data - annual mean and hourly mean at one central location in Yeovil.

Diffusion tube data - annual mean at 19 locations in Yeovil including a co-location study with an automatic analyser.

Automatic Monitoring Data

Both the annual mean and hourly mean concentrations of nitrogen dioxide measured during 2009 were less than the objective values. The following discussion of nitrogen dioxide concentrations collected using the automatic analyser at Yeovil Hospital is divided into:

• Annual Mean Objective • Hourly Mean Objective

Annual Mean Objective

Table 2.03 and Figure 2.2 and 2.3 show that the ambient concentration of nitrogen dioxide measured using the automatic monitor in Yeovil was less than the 40 µg/m3 annual objective and that the annual mean is consistent with monitoring since recording began in 2001. The annual mean objective concentration has not been exceeded at Yeovil Hospital since recording began in 2001.

Table 2.04 shows that the automatic monitor in Yeovil had variable data collection in some months. Two significant periods of data loss occurred in 2009, at the beginning of the year and from late May to mid August. A data retrieval issue with the ComVissioner software caused the period of data loss at the beginning of the year, which was resolved with a software upgrade, and the data loss from May to August occurred due to an air conditioning breakdown that in turn led to the failure of the analyser’s photomultiplier tube.

Progress Report


Despite these failures, the data are comfortably below the annual mean objective value.

Non-Automatic Monitoring

All nitrogen dioxide diffusion tube gauges are within the Yeovil Air Quality Management Area. Table 2.02 shows that diffusion tube gauges at Fiveways roundabout, Lyde road and Yeovil Bus Station are located on the roadside without relevant exposure to be early indicators of changes in air quality due to road traffic emissions.. If the objective has been exceeded at these locations, the concentration measured is used to estimate concentration at the nearest facade to determine. Data collection at Fiveways (yeo7), Lyde Road (yeo26), Hillside Residential Home (yeo402) and New Town (yeo504) were less than 90%. As the Yeovil automatic analyser had a data capture of below 90%, data from the Exeter and Bath roadside automatic analysers was used to estimate missing data, as in Appendix A. The concentration of nitrogen dioxide at two monitoring locations exceeded 40 µg/m3, but of these sites only Ilchester Road (YEO 11) has relevant exposure. Fiveways (YEO 7) is a roadside site and the exposure at relevant receptors where the objective applies has previously been estimated using the ‘NO2withDistancefromRoadsCalculatorIssue1’ tool provided by Air Quality

Progress Report 26


Consultants. The measured concentrations of nitrogen dioxide at this site have reduced since the 2008 and so the nitrogen dioxide air quality objective was not exceeded at Fiveways roundabout. The measured annual mean concentrations and collection efficiencies at two monitoring locations in 2009 was greater than 40 µg/m3 as shown in Table 2.06. However, neither of these locations had concentrations above 60 µg/m3, and so there are no indications that the hourly objective may have been exceeded.

2.6 Airborne Particles

There are two air quality objectives for airborne particles (PM10

): • Annual mean of 40 µg/m3

• 24-hour mean of 50 µg/m3 not to be exceeded on more than 35 days per year. Airborne particles were measured during 2009 using the Tapered Element Oscillating Microbalance. The data have been adjusted to the gravimetric equivalent and then amended using the Volatile Correction Model to take into account the volatiles that are lost when using the TEOM: the data is considered equivalent to a Filter Dynamic Measurement System. Due to data recording problems with the ComVissioner software at the beginning of the year, the data collection using the TEOM was 78%. The annual mean airborne particulate matter measured using TEOM in 2009 was 19.05 µg/m

3,

which is consistent with previous reporting as shown in Table 2.07. The annual mean objective has been achieved.

Figure 2.6 and Table 2.09 show that in 2009 there were only three days (18th March, 19th March and 3rd April) on which the concentration of airborne particles exceeded 50 µg/m3 which is less than the 35 times a year that the value can be exceeded and so the objective has been achieved.

2.7 Sulphur Dioxide

Ambient concentrations of sulphur dioxide were considered in the 2009 Updating Screening Assessment and are not measured in South Somerset. Emissions of sulphur dioxide are measured by some installations that hold certain types of Environmental Permits, and this data is available in the public register for each installation. Please contact Environmental Health on: 01458 257483 or email [email protected] for more information.

mailto:[email protected]

2.8 Benzene

Ambient concentrations of benzene were considered in the 2009 Updating Screening Assessment and are not measured in South Somerset. Emissions of benzene are minimised by larger petrol stations having both Stage 1 and 2 vapour recovery systems – vapour displaced during fuel delivery and when filling domestic vehicles is collected.

2.9 Ozone

Whilst ozone is not a specified pollutant, ozone is measured at the national background site at Charlton Mackrell. The non-statutory objective for ozone is 100 µg/m3 measured as a daily maximum of a running 8 hour mean. Figure 2.7 and Table 2.10 show concentrations of ozone during 2009. Data collection at the site was only 72% due to communication problems with the ComVissioner software (this failure effected both automated sites). However, given the trends in the data that is available, it is concluded that the objective has not been exceeded during 2009.

2.10 Summary of Compliance with AQS Objectives

New monitoring data collected in 2009 show that the concentrations of specified pollutants remain less than the national objective values, with the exception of nitrogen dioxide within the Yeovil Air Quality Management Area. Within the Yeovil Air Quality Management Area the concentration of nitrogen dioxide in only one location on Ilchester Road, was measured to be greater than the annual mean objective value of 40 mg/m3. In the previous year (2008) four locations exceeded the nitrogen dioxide objective. There is no requirement to proceed to detailed assessment for any pollutant within South Somerset.

Progress Report 34

3 New Local Developments Known sources of emissions and sensitive locations have been assessed during earlier rounds of air quality reporting. There have been no significant changes in South Somerset or neighbouring local authorities that are likely to impact upon air quality.

3.1 Significant Residential Developments

The residential development of 226 dwellings with at the Key Site development on Lyde Road, Yeovil (ST 5765 1773) is in progress with houses being built. As discussed in the 2009 Updating Screening Assessment, an air quality assessment has been carried out and submitted. This assessment conceded that the development would increase traffic past locations that are already exceeding the objective for nitrogen dioxide, but objective is not exceeded on the development itself. The development did not include a Section 106 agreements on air quality (see Chapter 5 for discussion of controls via Planning on developments in the district), although the developer is encouraging modal shift and is also installing a roundabout as part of the development (See Chapter 10).

3.2 Road Traffic Sources

Since the 2009 Updating Screening Assessment there have been no newly identified locations where road traffic emissions may cause objective values to be exceeded. The narrow streets with residential properties close to the kerb in Crewkerne were considered in the 2009 Updating Screening Assessment and this will be checked in 2012 Updating Screening Assessment to ensure this remains accurate.

3.3 Other Transport Sources

Since the 2009 Updating Screening Assessment there have been no newly identified locations of idling trains or airports that may affect air quality. The aircraft types using Yeovilton airport have changed in recent years, and reconsideration of this source may occur once aircraft types have stabilised. These changes are not considered to impact upon air quality.

3.4 Industrial Sources

Since the 2009 Updating Screening Assessment there have been no new or proposed installations for which an air quality assessment has been carried out and none where emissions are known to have substantially increased

• No large scale housing developments have been built (but see section 3.1 above) and no new relevant exposure is known to have been introduced into locations that are close to industrial sources of emissions. During the recession affordable housing has continued.

• In 2009 there was a planning application (09/01943/FUL) to construct an open cycle gas turbine generator on Pen Mill Trading Estate, Yeovil (ST 577 170). This site lies within the Yeovil Air Quality Management Area and so if it is built the emissions of nitrogen oxides from this combustion source will be considered in future air quality

Progress Report

assessments. The installation would be regulated via a Environmental Permit issued by the Environment Agency which would limit emissions.

• Larger petrol stations in the district have now upgraded to Stage 2 vapour recovery (displaced vapour is collected when filling customer cars). Given the adoption of vapour recovery and the squeeze on fuel prices (with the subsequent impacts on fuel throughput of fuel) emissions of Benzene are unlikely to have increased.

• An application is expected to operate a small waste oil burner at Preston Road, Yeovil.

• In 2009 there was a planning application (09/02865/FUL) for the erection of a 52,000 bird poultry shed at Southland Farm, South Cheriton (ST 7015 2488). This shed is an extension to an already permitted installation that is regulated by the Environment Agency under the Environmental Permitting regime. Whilst this individual shed is below the threshold of interest for Local Air Quality Management reporting, when combined with the other sheds brings the total farm stock to 145,000 birds, and it will be considered in the 2011 Updating Screening Assessment.

3.5 Commercial and Domestic Combustion Sources

Since the 2009 Updating Screening Assessment there have been no newly identified biomass combustion plants, and housing density has not changed and so the 2009 updating screening assessment remains valid.

3.6 New Developments with Fugitive or Uncontrolled Sources

There have been no new landfill sites, quarries, unmade haulage roads, or waste transfer stations since the last Updating and Screening Assessment:

South Somerset District Council confirms that there are no new or newly identified local developments which may have an impact on air quality within the Local Authority area.

4 Somerset Air Quality Strategy The Somerset Air Quality Strategy 3 is available on all the Somerset Council websites:

e.g. http://www.southsomerset.gov.uk/media/pdf/s/1/7_-_App_Final_version_Air_Quality_Strategy.pdfAlthough the actions in the Somerset Air Quality Strategy are for local authorities to implement at a local level, all Air Quality Management Areas in Somerset are due to traffic emissions and so the tasks generated by the Somerset Air Quality Strategy relies on Somerset Highways. Somerset Highways are a integral part of the Somerset Air Quality Steering Group. The aims and goals in the strategy are still being implemented and so it will not be reviewed before the next Local Transport Plan cycle in 2011 (see Chapter 7). The Somerset Air Quality Steering Group4 was instrumental in creating the strategy and remains the main vehicle to discuss and implement the tasks in the Somerset Air Quality Strategy. Implementation of the tasks is reviewed annually and report made to the Chief Environmental Health Officers group for Somerset. The aims of the strategy continue to be translated into tasks to be implemented by Air Quality officers across Somerset. Regular meetings of the Somerset Air Quality Steering Group allow officers to be kept appraised of current best practice in managing air quality. The Somerset Air Quality Strategy aims at harmonising and disseminating best practice to help all Somerset Local Authorities work towards achieving the national air quality objectives. Some of the tasks form part of each councils responsibilities such as the regulation required under the Environmental Permitting regulations, other actions such as Planning Policies are considered best practice and are over and above any statutory requirements. The Somerset Air Quality Strategy highlights links between air quality, climate change and sustainability:

• identify opportunities for local Authority partnership working and coordinate (e.g. Officer Steering Group)

• Identify key actions and initiatives to encourage local Authority departments, other organisations and the general public to take action to minimise as far as practicable their impact on air quality e.g. carbon training day

• Provide guidance and input on air quality issues for use in development planning and transport.

• planning processes and policy development • Ensure consistent implementation and the consideration of air quality issues in

the Local • Pollution Prevention and Control/Environmental Permits help regulate and in

some cases monitor emissions to air from certain industry types. • Highlight links between air quality, climate change and sustainability

The aims and tasks within the Somerset Air Quality Strategy are being translated into a Somerset Air Quality Strategy Action Plan, some of the actions from the draft version are shown in Table 4, next and following pages. .

5 Planning Applications There have been no new planning applications that match the criteria for significant new developments since the 2009 Updating Screening Assessment. In 2009 two planning applications of note that have been approved:

• a planning application (09/01943/FUL) to construct an open cycle gas turbine generator on Pen Mill Trading Estate, Yeovil (ST 577 170). This site lies within the Yeovil Air Quality Management Area and so if it is built the emissions of nitrogen oxides from this combustion source will be considered in future air quality assessments. If built, the installation would be regulated via a Environmental Permit issued by the Environment Agency which would limit emissions.

• a planning application (09/02865/FUL) for the erection of a 52,000 bird poultry

shed at Southland Farm, South Cheriton (ST 7015 2488). Larger poultry units may have an impact upon local concentrations of both PM10 and nitrogen although Local Air Quality Management currently only considers their inputs of particulate matter. This shed is an extension to an already permitted installation that is regulated by the Environment Agency under the Environmental Permitting regime. Whilst this shed is below the threshold for Local Air Quality Management reporting, when combined with the other sheds brings the total farm stock to 145,000 birds. Current guidance is to wait until national guidance is available for this source.

These sources will therefore be considered in future Air Quality Reports. Ongoing developments inside the Yeovil Air Quality Management Area but not within areas exceeding national objectives include:

• housing development at the Lye Road key site has been discussed earlier in this report. The submitted air quality assessment report showed that development will contribute to increased traffic flows past locations that already [marginally] exceed the objective value for nitrogen dioxide. However, the development site is not in a location that exceeds of any air quality objective, and its contribution to the air quality impacts is minimal as the air quality management area is largely due to through traffic.

Progress Report 40

6 Air Quality Planning Policies There is increasing consistency within air quality policies at various scales. This Chapter will discuss planning at the regional scale and focus in on the policies used locally. Regional Spatial Strategy

The South West’s draft Regional Spatial Strategy policy on air quality, states that

‘the impacts of development proposals on air quality must be taken into account and local authorities should ensure, through Local Development Documents, that new development will not exacerbate air quality problems in existing and potential Air Quality Management Areas.’

Whilst there is no overlap at the air quality officer level between the organisations, this policy will help avoid receptors being added to sensitive locations within Local Air Quality Management Areas.

6.1 Planning

Local Planning is influenced by the Planning Policy Guidance. Planning Policy Statement 1 (PPS1) on Delivering Sustainable Development5 suggests that planning departments should take account of environmental issues such as air quality and pollution, and Planning Policy Statement 23 (PPS 23) states that air quality is a material planning consideration (Annex 1 of PPS 23). As Yeovil has a Air Quality Management Area, air quality is considered a material planning consideration. Whilst the whole of Yeovil is a Air Quality Management Area, planning use a ‘constraints layer’ when considering any planning application – any planning applications within a buffer zone of the A30 are referred to Environmental Health for comments. This is intended to ensure that no further receptors are introduced to locations where air quality may have exceeded objective values. Any significant development near to the through routes in Yeovil are required to show both that the air quality will not be made significantly worse in that location, and that it would likely to render any improvement in air quality unworkable. The Lyde Road Development was permitted as local traffic is only a contributory rather than the cause of the marginal Exceedence of objectives. Lyde Road Key Site is within the Air Quality Management Area, although it is not an area that exceeds objective values. Due to model shift which is being encouraged as part of the development, it is unlikely to render any improvement in air quality unworkable. One of the aims of the Somerset Air Quality Strategy is to work towards common approaches across the region and to create a common source document to use as a Supplementary Planning Document. South Somerset was one of the first councils to implementation a whole town Air Quality Management Area and is committed to maintaining and improving air quality for the whole of the district. 5 Department of Communities and Local Government (DCLG), 2005.

6.2 Section 106 agreements

Section 106 Agreements may be used to fund any mitigation or monitoring required as a result of a development. They have not yet been used in South Somerset, but nearby councils of Mendip District Council and Mid Devon have used Section 106 Agreements with developers to alleviate air quality concerns.

There are many ways that Section 106 Agreements can be used. Several Years ago in a developer in Mendip District set aside a bond in case the air quality in Frome was shown to have deteriorated as a result of their development. This technique may not necessarily be appropriate for other councils to use as linking deteriorating air quality to specific developments is problematic. A Supplementary Planning Document is now being adopted by Mendip to make the securing and releasing of such moneys more straight forward. More recently, Mid Devon District Council requested money to fund infrastructure changes via a Section 106 agreement with a developer.

Whilst the residential development of the Key Site on Lyde Road Yeovil will contribute additional emissions to the Air Quality Management Area, the Section 106 Agreement in this development did not include Air Quality consideration. However, the developer has promoted modal shift to public transport, infrastructure to encourage walking and cycling as part of the development.

Section 106 Agreements remain a viable tool that may be used by the council in future applications.

Progress Report 42

7 Local Transport Plan 3 Emissions from road traffic are primarily influenced by national policy dictating fleet composition (improving engine emissions) and Somerset Highways controlling the flow of traffic locally6: The local council has no direct influence on either factor, but does provide monitoring information to Somerset Highways so that the routing of traffic is better informed to avoid exacerbating air quality problems in certain locations. The Local Transport Plan 2 concluded that congestion is the main cause of poor air quality and current trends indicate that congestion is likely to get worse due to significant housing developments already planned for the town. Transport modelling work carried out as part of LTP2 showed that even significant investment in a variety of different transport measures will only slow the growth of congestion and not reduce it in Yeovil. The Local Transport Plan 27 contained a chapter on congestion and Air Quality. The next Local Transport Plan (LTP3) does not contain such a chapter, but instead contains a broad framework of strategic goals, and is intended to help local authorities highlight air quality issues. The LTP3 cycle will begin in 2011, and Somerset Highways have published several guidance documents for Local Transport Plan 3. These documents include an Environment Strategy that includes the management of air quality:

8 Carbon Reduction and Climate Change Adaptation Strategy

Defra’s Report Air Pollution: Action in a Changing Climate8 released in March 2010 highlights the additional health benefits that can be achieved through closer integration of air quality and climate change policies. Climate Change has already been considered within the Somerset Air Quality Strategy (see Chapter 4), and South Somerset District Council also has a specific Carbon Reduction and Climate Change Adaptation Strategy 2008 - 20129 (The Climate Change Strategy). South Somerset was the first council in Somerset to sign the Nottingham Declaration on Climate Change (2006) and publish a protocol on Climate Change. The council aims to be one of the top exemplar councils in the country in reducing carbon dioxide emissions by 2012 (Objective 19 of the councils Corporate Plan 2005). The Climate Change Strategy was endorsed by South Somerset members in 2008 and the council has been acknowledged by the Energy Savings Trust and the CPA inspection 2008 as showing commitment to climate change. Climate change and air quality were both considered in the Somerset Air Quality Strategy due to the interplay of climate change and air quality:

1) win-wins tackling both climate change and air quality emissions by reducing emissions (e.g. promoting modal shift in transport) or my generating energy without entailing carbon miles e.g. biogas from aerobic digestion vide Biogas Regions brochure10

2) win-lose biofuel combustion, large or older designs incinerators, may help reduce national emissions of greenhouse gases but would locally increase PM10. To date, within South Somerset, the applications for biomass plants have not been in areas of air quality concern (there are no such areas for particulate matter). If an air quality objective has been exceeded, then the choice of climate change technology will be further focused towards technology that does not impact upon air quality. The Planning system (see Chapter 5) is the regulatory framework to ensure such applications are considered fully.

3) lose-wins Options that are good for local air quality such as centralised power generation are likely to be heavily subsidised by local power generation and so Air Quality will be protected through the planning regime.

The Carbon Reduction and Climate Change Adaptation Strategy. The council continues to work towards:

a) Leading The council considers ways to reduce its own carbon emissions. This is led by Climate Change emphasis, National Indicator 185 ‘carbon

dioxide reduction from local Authority operations’ and the agreed targets in the Local Area Agreement. The council had already joined the Carbon Trust’s Local Authority Carbon Management Programme, and a carbon management team of officers identified the council’s baseline carbon emissions. The council procures 65% of our electricity from ‘green’ renewable sources.

b) Helping The council act as a community leader in helping others to reduce their carbon emissions (led by Climate Change Bill, National Indicator 186 ‘Per capita carbon dioxide emissions in the local Authority area’.). An example is the helping of applications for grant funding for renewable energy generation at 7 mill sites, and a wind turbine on the Yeovil Innovation Site.

c) Adapting The council will adapt to the impacts and opportunities of climate change both impacts and also policy changes (led by Climate Change Bill, National Indicator 188 ‘Adapting to Climate Change’ and the agreed targets in the Local Area Agreement. South Somerset is ideally placed to take advantage of renewable energy; there are few air quality problems to stifle innovation, and great scope for biofuel production due to the rural landscape, warm moist climate. The planning system will have the challenging task of encouraging new innovation in technologies and policies whilst avoiding less well thought out test and demonstration plants in inappropriate locations.

Green Energy in South Somerset Within Somerset, the district of South Somerset remains the district with the highest [non domestic] installed renewable electricity capacity at 4.38 MW. The location of these installations can be seen in Figure 8.1 as viewed on the renewable energy atlas from RegenSW11 and their summary documents (http://www.surveys.energysw.com/somerset-biomass-thermal.php).

9 Yeovil Air Quality Action Plan This Chapter summarises changes in the Yeovil Air Quality Action Plan. In previous years a separate Yeovil Air Quality Progress Report was submitted to Defra, but in this and future years it will be integrated into the Updating Screening Assessment or Progress Report.

9.1 Summary

South Somerset District Council in conjunction with Somerset Highways developed an Air Quality Action Plan to manage air quality in the Yeovil Air Quality Management Area (AQMA). Each year the council produces an annual report to update stakeholders on the progress made in the pursuit of the actions in the Air Quality Action Plan. This is the fourth progress report on actions within the management area. The national air quality objective for nitrogen dioxide continues to be exceeded at several roadside locations in Yeovil and so the AQMA is to remain in force. The Fifth Report for the House of Commons Environmental Audit Committee states that local authorities have a key role in delivering improved air quality, however district and borough councils have no control over Highways Authority management and their main role is providing information to Somerset Highways and managing exposure by not introducing receptors in or near locations sensitive to emissions. This report summarises actions to manage local air quality within the Yeovil Air Quality Management Area since the 2008 report. SSDC promotes procedures that are sympathetic to air quality and is using the Planning System to encourage modal shift in essential developments and by minimising new receptors being located within vulnerable areas. The council is also looking at ways to reduce both its own and its staff contribution to transport emissions.

9.2 Previous Reports

Concentrations of nitrogen dioxide in Yeovil were considered further in Round 1 when modelling indicated that in 2005 the annual mean objective for nitrogen dioxide might be exceeded at receptors near the A30 and A37. The Yeovil Air Quality Management Area was declared In August 2003 and ways of reducing concentrations of nitrogen dioxide were investigated and an Air Quality Action Plan for Yeovil was contained in the 2004 Air Quality Progress Report . Since 2004 then there have been 4 reports about the Yeovil Air Quality Management Area:

• Air Quality Action Plan 2005 • Yeovil Air Quality Management Area Progress Report 2007 • Yeovil Air Quality Management Area Progress Report 2008 • Yeovil Air Quality Management Area Progress Report 2009

The Yeovil air quality management area, was shown in Figure 1.3, next page, included the whole town rather than just the actual locations of exeedance. The planned

Progress Report 46



http://www.southsomerset.gov.uk/media/pdf/5/f/AQAP_Progress_report_2007.pdf

solutions require wider scale management of both local and through traffic flows than could be achieved by declaring only the locations of Exceedence12.

9.3 Air Quality Progress Indicators

Seven monitoring locations within the Yeovil Air Quality Management Area are used by Somerset Highways to provide reporting trends for the Local Transport Plan. Table 9 below shows the monitoring data collected since 2005 (baseline year) and the concentration in 2010.

Box 2.1 Pg 2-4

Table 2.01 shows that in 2010 concentrations of nitrogen dioxide were measured as being greater than objective concentration of nitrogen dioxide at the monitoring location on Ilchester Road.

12 The whole town approach has many advantages and is increasingly seen as the apposite way of managing local air quality problems relating to traffic emissions. The most recent whole town Air Quality Management Area being declared is Coventry which was declared for nitrogen dioxide.

The chemiluminescent nitrogen dioxide monitor in central Yeovil which provides real time monitoring of nitrogen dioxide. As discussed in Chapter 2, collection was reduced by instrument failure, however, many locations continued to be monitored during this period using nitrogen dioxide diffusion tube gauges. Current data shows that the through traffic is still causing the annual mean objective for nitrogen dioxide to be exceeded and so the Yeovil Air Quality Management Area is to be retained and further detailed assessment to assess changes in this source is not required.

9.4 Somerset Air Quality Steering Group

The Somerset Air Quality Steering Group is comprised of air quality officers from every district and borough council in Somerset and the County Council. In order to harmonise approaches to air quality, in 2009 the steering group released its collaborative document the Somerset Air Quality Strategy. The strategy sets out a comprehensive approach for air quality improvements throughout the county. The report was peer reviewed by Air Quality Consultants to ensure that it included all current air quality issues and it has been adopted (or recognised - depending upon the regulatory style of each LA) by all Somerset LAs. The document included actions for the promotion of common policies such as the production of planning guidance.

9.5 Actions to Promote Air Quality

The primary actions required to protect and maintain air quality in the Yeovil Air Quality Management Area are largely under the control of Somerset Highways rather than the district council. Whilst Somerset Highways is the primary controller of traffic emissions, South Somerset District Council has some influence over receptor location via the planning system, can promote modal shift in new developments. The district council can also increase corporate and local awareness by leading by example. The actions in the Yeovil Action Plan have been incorporated into the Somerset County Councils Local Transport Plan (2005 – 2011) and these will be carried forward into the Somerset Local Transport Plan 3.

9.5.1 Planning Control

Transport modelling work carried out for the Local Transport Plan 2 showed that even significant investment in a variety of different transport measures will only slow the growth of congestion and not reduce it. The LTP report concluded that the worsening congestion is likely to be due to significant housing developments. However, significant residential development is needed to satisfy local needs for houses and so development has been allowed to continue but with a strong emphasis on measures to promote modal shift - air quality is only one of several considerations for both Development Control and Somerset Highways.

Progress Report 48

The development of 119 residential units near Lyde Road was granted planning permission ref 08/04785/REM. The air quality objective at Lyde Road already exceeds national objectives and so there is no ‘spare capacity’ for development in this area of Yeovil.

9.5.2 Carbon Reduction Day

Councillors and staff at South Somerset District Council attended a Carbon Reduction Technology day on 15th April 2010. This workshop highlighted technology that the council and local business may use to reduce energy use and so reduce carbon emissions; i.e. win-wins for air quality (see Chapter 8)

9.5.3 Action Quality Action Plan - Progress

Somerset Highways has been the key partner in the Yeovil Vision initiative, and has been working alongside South Somerset District Council, Yeovil Town Council and the South West Regional Development Agency to maintain and enhance air quality in Yeovil. The Yeovil Air Quality Action Plan was integrated into Highways Authority’s Local Transport Plan ‘Local Transport Plan 2’ (2005 – 2011) although some of the actions are still in progress will be taken forward into the Local Transport Plan 3 cycle (see Chapter 7). Many of the actions are being considered and implemented by Highways. The actions completed and timescale are summarised in the Somerset Local Transport Plan 2 progress report , which was supplied on 24 April 2009, the original Yeovil Air Quality Action Plan is summarised in the tables below for information only.

Progress Report 62

9.6 Summary

Progress on the actions of the Yeovil Air Quality Action Plan continue to be completed. Concentrations of nitrogen dioxide in the Yeovil Air Quality Management Area continue to exceed objective values and so the Yeovil Air Quality Management Area must be retained and the boundaries are appropriate for the management of this particular through traffic related source. No changes to either the declaration or boundaries of the Air Quality Management Area are required. Whilst fewer locations were measured as exceeding the annual mean objective for nitrogen dioxide, this may be due to the impacts of the uncertain economic climate and the impact of rising petrol prices and so the trends should be viewed with caution. Progress continues to be made through the Local Transport Planning system to minimise worsening congestion and emissions although Somerset Highways. Local measures are also being used including using the planning process to promote modal shift in significant developments and examining ways to minimise the councils own contribution.

Progress Report 2

10 Conclusions and Proposed Actions

10.1 Conclusions from New Monitoring Data

New monitoring data collected in 2009 continues to show that the concentrations of specified pollutants remain less than the objective values, with the exception of nitrogen dioxide within the Yeovil Air Quality Management Area. As there is already an Air Quality Action Plan for nitrogen dioxide from traffic emissions in Yeovil, There is no requirement to proceed to detailed assessment for any pollutant within South Somerset.

10.2 Conclusions relating to New Local Developments

No new local developments that are considered likely to impact upon air quality assessment have occurred since the 2009 Updating Screening Assessment.

10.3 Other Conclusions

Actions in the Yeovil Air Quality Action Plan and the Somerset Air Quality Strategy continue to be implemented by Somerset Highways.

10.4 Proposed Actions

New monitoring data collected during 2009 has not identified the need to proceed to a Detailed Assessment for any pollutant. Compared to 2008, there were fewer measured Exceedences where the annual mean objective for nitrogen dioxide applies. The existing Air Quality Management Area will be retained in its current form. The next report will be the 2011 Progress Report

They are deployed according to the procedures given in the UK Nitrogen Dioxide Diffusion Tube Network Instruction Manual. A travel blank is included in each batch, along with triplicate deployment at the Yeovil automatic monitoring station so that a local bias adjustment factor can be calculated if sufficient data is available. QA/QC of diffusion tube monitoring The diffusion tube gauges are analysed by a Gradko International Limited. This laboratory is a participant in the WASP inter-comparison scheme and has had a performance classified as “good” in that scheme over the duration of the survey. Gradko actively participated in and provided input to the Working Group on Harmonisation of Diffusion Tubes from which the Harmonisation Practical Guidance was derived. Diffusion Tube Bias Adjustment Factors The diffusion tube results have been bias adjusted using the bias adjustment factor from the national database of co-location studies (?date which one?). This figure had to be used as the Yeovil automatic nitrogen analyser had a data capture below 90% (discussed later). The bias adjustment figure of 0.92 was used. Factor from Local Co-location Studies (if available) Due to poor data collection a Local Co-location Factor was not used in 2009. Short-term to Long-term Data adjustment Four sites had limited data collection and so the annual mean was estimated using prescribed method.

Automatic Monitoring The QA/QC procedures for the Chemiluminescence N-oxides analyser and Tapered Element Oscillating Microbalance are summarised in this section. The QA/QC procedures for the Chemiluminescence N-oxides analyser The quality assurance and quality control procedures are based on the UK Automatic Network Site Operator's Manual. Instrument Calibration includes:

• Daily - ‘automatic’ calibrations using the auto span and auto zero facility of the instrument to show long-term drift. These results are not used for data scaling.

• Fortnightly - manual calibrations conducted using a UKAS accredited gas standard and a zero air scrubber. The calibration data is used to scale the

• raw data and show instrument drift. This calibration data is not used to alter the instrument response factors in any way.

• Biannual reference calibrations by service engineers using calibration standard.

Data capture A data capture rate for ratified data of 54.1% has been achieved in 2009. Data ratification and validation Once calibration factors have been applied, the data set is checked and any unusual or spurious measurements are flagged for further investigation. The data is reviewed every 3 months to ensure that it is reliable and consistent. The QA/QC procedures for the Tapered Element Oscillating Microbalance Service engineers conduct the quality assurance and quality control procedures on the TEOM. Data Adjustment procedures for the TEOM The data collected using the TEOM was adjusted to the gravimetric equivalent so that the data is to European Standards. Additionally, data collected since 2008 (as reported in the 2009 Updating Screening Assessment) has been adjusted for lost volatile particles. As the TEOM heats the air inflow pipe, leading to the loss of and hence under estimation of volatile particles. The data collected using the TEOM are therefore adjusted by reference to the nearest Filter Dynamic Measurement System-TEOM so that these volatile particles can be estimated. This correction method is known as the Volatile Correction Model.
