Executive Summary

The UK Government published its strategic policy framework for air quality management in 1995
establishing national strategies and policies on air quality which culminated in the Environment Act,
1995. The Air Quality Strategy1 provides a framework for air quality control through air quality
management and air quality standards. These and other air quality standards1 and their objectives
have been enacted through the Air Quality Regulations in 1997, 2000 and 20022. The Environment
Act 1995 requires Local Authorities to undertake air quality reviews. In areas where an air quality
objective is not anticipated to be met, Local Authorities are required to establish Air Quality
Management Areas and implement action plans to improve air quality.

The second round of air quality review and assessments has been completed by The Borough of
Poole. The Local Authority are now required to proceed to the third round of review and assessment
in which sources of emissions to air are reassessed to identify whether the situation has changed since
the second round, and if so, what impact this may have on predicted exceedences of the air quality
objectives.

The third round of review and assessment is to be undertaken in two steps. The first step is an
Updating and Screening Assessment, which updates the findings of the previous Review and
Assessment cycle, undertaken for all pollutants identified in the Air Quality Regulations. Where a
significant risk of exceedence is identified for a pollutant it will be necessary for the local authority to
proceed to a Detailed Assessment. Where a local authority does not need to undertake a Detailed
Assessment, a progress report is required instead.

This report is equivalent to an Updating and Screening Assessment for The Borough of Poole as
outlined in the Government‟s published guidance.

The Borough of Poole has completed the following review and assessments of air quality to date:

          Stage 1 (2000)

          Stage 2 (2000)

          Updating and Screening Assessment (July 2003)

          Progress Report (April 2004)

          Progress Report (April 2005)

          Detailed Assessment of Nitrogen Dioxide in Poole Road, Commercial Road, Ashley Road
           and Mountbatten Roundabout (June 2005)

The conclusions of this updating and screening assessment are:

A detailed assessment is not required for carbon monoxide, benzene, 1,3-butadiene, lead, nitrogen
dioxide, sulphur dioxide and PM10.

At two locations within the Borough (Ashley Road and Mountbatten Roundabout), further NO 2
monitoring was pursued to confirm concentrations. Three-month continuous monitoring results at
Ashley Road indicated that NO2 concentrations were below the annual mean objective for NO2. An
updated dispersion modelling assessment (April 2006) was also made at this location and the
continuous monitoring data was used to verify the model. The results indicated that whilst it is
likely that annual average NO2 concentrations are close to exceedence along the southern side of

 Refers to standards recommended by the Expert Panel on Air Quality Standards. Recommended standards are set purely
with regard to scientific and medical evidence on the effects of the particular pollutants on health, at levels at which risks to
public health, including vulnerable groups, are very small or regarded as negligible.

Ashley Road, there are no areas of exceedence at locations where the objective would apply in
2005, i.e. no relevant receptors.

Diffusion tube monitoring at Mountbatten Roundabout was relocated to Dolberry South Road where
relevant exposure occurs and the results collected to date indicated that the level was also below
the 2005 objective. It is recommended that a longer period of observations should be made at this
location and to report results in the next progress report.

Based on these findings, there is currently no need for the Borough of Poole to declare an AQMA at
either Ashley Road or areas in the vicinity of the Mountbatten Roundabout. However, it is
recommended that The Borough of Poole keep these locations under review and report findings in
the next progress report.

The difference between ‘standards’ and ‘objectives’ in the UK AQS

Air quality standards (in the UK AQS) are the concentrations of pollutants in the atmosphere that
can broadly be taken to achieve a certain level of environmental quality. The standards are based
on assessment of the effects of each pollutant on human health including the effects on sensitive
subgroups. The standards have been set at levels to avoid significant risks to health.

The objectives of the UK air quality policy are framed on the basis of the recommended standards.
The objectives are based on the standards, but take into account feasibility, practicality, and the
costs and benefits of fully complying with the standards.

Specific objectives relate either to achieving the full standard or, where use has been made of a short
averaging period, objectives are sometimes expressed in terms of percentile compliance. The use of
percentiles means that a limited number of exceedences of the air quality standard over a particular
timescale, usually a year, are permitted. This is to account for unusual meteorological conditions or
particular events such as November 5th. For example, if an objective is to be complied with at the
99.9th percentile, then 99.9% of measurements at each location must be at or below the level
specified.

1           Introduction to the Updating and Screening
            Assessment


1.1         PURPOSE OF THE UPDATING AND SCREENING ASSESSMENT

The first and second rounds of air quality review and assessments are now complete and all local
authorities should have completed all necessary stages. Where the likelihood of exceedences of air
quality objectives have been identified in areas of significant public exposure, an air quality
management area should have been declared, followed by a Further Assessment, and the formulation
of an action plan to eliminate or reduce exceedences. Local authorities are now required to proceed to
the third round of review and assessment in which sources of emissions to air are reassessed to
identify whether the situation has changed since the second round of review and assessment, and if
so, what impact this may have on predicted exceedences of the air quality objectives. Such changes
might include significant traffic growth on a major road, which had not been foreseen, construction of
a new industrial plant with emissions to air, or significant changes in the emissions of an existing
plant.

The third round of review and assessment is to be undertaken in two steps. The first step is an
Updating and Screening Assessment, which updates the findings of the previous Review and Assessment
cycle undertaken for all pollutants identified in the Air Quality Regulations. Where a significant risk of
exceedence is identified for a pollutant it will be necessary for the local authority to proceed to a
Detailed Assessment. Where a local authority does not need to undertake a Detailed Assessment, a
progress report is required instead.

1.2         OVERVIEW OF APPROACH TAKEN

The general approach taken to this Updating and Screening Assessment was to:
            Identify the conclusions of the last round of review and assessment for each of the
             seven pollutants included in the air quality regulations;
            Identify significant sources of emissions to air for the seven pollutants included in the
             air quality regulations, including major roads and industrial plant;
            Identify new sources not previously considered in the second round of review and
             assessment;
            Identify any sources for which emissions have changed significantly since the last
             round of review and assessment;
            Identify and interpret the significance of air quality monitoring data made available
             since the last round of review and assessment;
            Assess the risk of exceedences of the air quality objectives in locations where relative
             public exposure may exist using screening models and nomograms; and
            Where necessary, identify locations and pollutants for which further detailed
             assessment of air quality will be required.

2        The UK Air Quality Strategy


The Government prepared the Air Quality Strategy for England, Scotland, Wales and Northern
Ireland for consultation in August 1999. It was published in January 2000 (DETR, 2000) 2.


2.1.1     National Air Quality Standards
At the centre of the Air Quality Strategy is the use of national air quality standards to enable air
quality to be measured and assessed. These also provide the means by which objectives and
timescales for the achievement of objectives can be set. These standards and associated specific
objectives to be achieved between 2003 and 2010 are shown in Table 1.1. The table shows the
standards in g m-3.

2.1.2    Timescales to achieve the objectives for the pollutants in Air Quality Strategy

In most local authorities in the UK, objectives will be met for most of the pollutants within the
timescale of the objectives shown in Table 2.1. It is important to note that the objectives for NO2
remain provisional. The Government has recognised the problems associated with achieving the
standard for ozone and this will not therefore be a statutory requirement. Ozone is a secondary
pollutant and transboundary in nature and it is recognised that local authorities themselves can exert
little influence on concentrations when they are the result of regional primary emission patterns.

2.2      AIR QUALITY REVIEWS – THE APPROACHES AND EXPECTED
         OUTCOMES

Technical Guidance has been issued in „Review and Assessment: Technical Guidance‟ LAQM.TG (03)1
to enable air quality to be monitored, modelled, reviewed and assessed in an appropriate and
consistent fashion. This updating and screening assessment has considered the procedures set out in
this technical guidance.

The primary objective of undertaking a review of air quality is to identify any areas that are unlikely to
meet national air quality objectives and ensure that air quality is considered in local authority decision
making processes. The complexity and detail required in a review depends on the risk of failing to
achieve air quality objectives and it has been proposed therefore that reviews should be carried out in
two steps. Both steps of review and assessment may be necessary and every authority is expected
to undertake at least a first stage review and assessment of air quality in their authority area. The
steps are briefly described in the following table, Table 2.1.




                                                                                                 netcen   4

                                                                 authorities already prepare.



      The current deadline for completion of updating and screening assessments is April 2006, and for
      detailed assessments April 2007.

2.3   LOCATIONS THAT THE REVIEW AND ASSESSMENT MUST
      CONCENTRATE ON

      For the purpose of review and assessment, the authority should focus their work on locations
      where members of the public are likely to be exposed over the averaging period of the objective.
      Table 2.2 summarises the locations where the objectives should and should not apply.

It is unnecessary to consider exceedences of the objectives at any location where public exposure
over the relevant averaging period would be unrealistic. Locations should also represent
non-occupational exposure.

3           Information used to support this assessment


This section lists the key information used in this review and assessment.

3.1         CONCLUSIONS FROM THE FIRST AND SECOND ROUND OF
            REVIEW AND ASSESSMENT OF AIR QUALITY FOR THE
            BOROUGH OF POOLE

The Borough of Poole has completed the following review and assessments of air quality to date:

           Stage 1 (2000): After due consideration of air pollution monitoring data from both local
            and national datasets the Objectives for benzene, 1,3-butadiene, carbon monoxide, lead
            and sulphur dioxide are likely to be met. However, the prevailing Objectives for nitrogen
            dioxide and PM10 may not be met in 2005.

           Stage 2 (2000): A second stage review was carried out for NO2 and PM10. It concluded
            that there was little risk that the air quality objective for both pollutants would be
            exceeded in the area because of road traffic emissions. The report recommended that a
            third stage review and assessment for NO2 and PM10 was not required.

           Updating and Screening Assessment (July 2003): An Updating and Screening Assessment
            (USA) was carried out to identify new sources or further risks to air quality in the area
            and further assess the risk of exceedences of the air quality objectives. It concluded that
            a detailed assessment was not required for any pollutants and that air quality objectives
            were likely to be met. However, it was reported that the NO 2 diffusion tube site at Poole
            Road should be investigated in detail for the next progress report.

           Progress Report (April 2004): All monitoring data for 2003 was assessed within this
            report and it highlighted that the 2005 annual mean objective for NO 2 could be at risk of
            exceedence at four locations. These locations were Poole Road, Ashley Road, Commercial
            Road and Mountbatten Roundabout. The Borough of Poole concurred with the advise of
            DEFRA in September 2004 to proceed to a detailed assessment at these four locations to
            assess further these risks of exceedence.

           Progress Report (April 2005): All monitoring data for 2004 was assessed within this
            report and the results were similar to that of the 2003 results and the USA report. It was
            still likely that all of the measured pollutants and monitored sites would meet the national
            objectives, with the exception of four sites proceeded to the Detailed Assessment for NO 2

           Detailed Assessment (June 2005): A detailed assessment was undertaken for NO 2 at
            Poole Road, Ashley Road, Commercial Road and Mountbatten Roundabout which involved
            the use of dispersion modelling techniques. The results of the assessment showed that
            the 2005 annual mean objective of 40 m-3 for NO2 would be met at the locations
            assessed in Poole Road and Commercial Road. However, there was the possibility of
            exceedences of this objective at some locations on the southern side of Ashley Road and
            at properties in the vicinity of the Mountbatten Arms roundabout.

The Detailed Assessment report recommended that The Borough of Poole should consider declaring
an AQMA if relevant exposure is confirmed to occur at Ashley Road and at the Mountbatten Arms
roundabout where exceedences of the objective have been predicted.

Based on the findings of the Detailed Assessment, the Borough have decided not to declare an
AQMA at this stage for the following reasons:

           Both assessments at Ashley Road and Mountbatten Roundabout were based purely on
            diffusion tube monitoring and modelling techniques to predict the 2005 and 2010
            concentration of nitrogen dioxide, no real time monitoring had been undertaken at these
            locations.



                                                                                               netcen   8
                                                                       AEAT/ENV/R/2209/Issue 1


          Results for Ashley Road were only marginally above the 2005 annual average objective
           for NO2, and for the Mountbatten Roundabout there is no relevant exposure where the
           diffusion tube was located.

The Borough of Poole have sought permission from Defra to pursue further investigation at these
locations to confirm the likelihood of exceedence. Such an approach is in accordance with LAQM.
TG(03) paragraph 1.2.3 which states:

“Where uncertainties are potentially high and the outcomes is marginal, then the authority should
look to obtaining more reliable data to improve the confidence in its decision”

Defra has accepted the request from The Borough of Poole to carry out further investigation at
these two locations. This would involve undertaking a 3-month continuous monitoring programme
at Ashley Road and relocation of the diffusion site to relevant exposure at Mountbatten
Roundabout.

The Borough of Poole has not declared an Air Quality Management Area to date.


3.2        PROPOSED DEVELOPMENTS WHICH MAY AFFECT AIR QUALITY

Any new developments in the local authority area, or outside the LA that may have an impact on
local air quality need to be considered. Key considerations should include:

   Industry
   Housing and redevelopment
   Road Network changes

3.2.1    Industry
There are no new significant industrial developments in The Borough of Poole apart from those that
have already been addressed in the 2003 USA report.

3.2.2      Housing and redevelopment

The Progress Report of 2004 and 2005 discussed two main developments:

         The Pitwines development – a former gas works site where planning permission was
          granted to build 500 new homes, was commenced in May 2004. PM10 monitoring was
          required as a planning condition during the construction phrase to ensure that the objective
          for PM10 is not breached. This development is nearly complete now and all the groundwork
          remediation has finished. There was no problem with regard to particulate emissions.

         The Second Lifting Bridge (between Poole Town and Hamworthy) – this development
          was also addressed in the 2003 USA. An Environment Statement was produced which
          include assessment of the effects of this development on air quality using the DMRB
          methodology. It was concluded that the development would not cause any exceedence of
          the air quality objectives and that air quality was likely to improve due to improvement of
          congestion problem. Air quality issues and cumulative effect of such development will be
          examined further when planning permission is to be granted. This development is still at a
          review stage and it has been subjected to a public enquiry but the results are not known
          yet.

The 2005 Progress Report also highlighted that the Borough of Poole have been made aware of
four proposed major developments within 2004, which may have an effect to local air quality:

         The Former Power Station Site – Linked to the „Full Sail Ahead‟ Regeneration
          programme to redevelop Lower Hamworthy, with plan to build 1100 homes and other
          facilities. An Environmental Statement has been submitted to the Borough of Poole which
          included a chapter on Air Quality. The assessment showed that it would not cause adverse
          effects to local air quality and the nitrogen dioxide and particulate objectives due to the
          nature of the road links. This development is at the outline stage at present.




                                                                                             netcen   9
                                                                      AEAT/ENV/R/2209/Issue 1


       Sydenhams - Linked to the „Full Sail Ahead‟ Programme to develop land currently
        occupied by Sydenhams, with plan to build 274 homes and mixed use over 2 hectare land.
        An Environmental Statement has been received in relation to air quality effects of this
        proposal. The Borough of Poole request further information where BoP monitoring data can
        be used to substantiate the modelling at specific receptor locations. This development is at
        the outline stage at present.

       The Thistle Hotel – Redevelopment of the Thistle Hotel on Poole Quay. An Environmental
        Statement has been submitted, however no adverse effects to local air quality were
        recorded although the Borough of Poole have advised all appropriate mitigation measures
        for construction dusts be adopted due to its sensitive location and the nature of the sites
        former use as a Gas Works. No update progress with regard to this development since the
        2005 Progress Report.

       Poole Goods Yard – Redevelopment of Poole Railway and its associated Goods Yard with
        residential and commercial units. A local air quality assessment has been undertaken and
        the dispersion modelling results indicated that the development would not cause any
        exceedences of the statutory objectives for NO2 and PM10. Release of dust and PM10 were
        likely to occur during construction phase, however, the impact would be reduced or
        prevented through good site practice and the implementation of suitable mitigation
        measures.

3.2.3    Transport Issues and the Local Transport Plan

The Borough of Poole jointly produce the Local Transport Plan (LTP) with Bournemouth Borough
Council and Dorset County Council. A second LTP (provisional) has been recently produced which
sets out a strategy for transport in South East Dorset for the five-year period 2006-2011. This
follows the previous plan published in July 2000 that covers the 2001 to 2006 period.

Major schemes and strategy cited within the LTP (2006-2011) which is of relevant to Poole include:

       A31-to-Poole corridor improvements
       Development of Prime Transport Corridors (A35 corridor between Poole and Bournemouth
        Town Centres)

These schemes and strategy will be aimed at reducing congestion and improve accessibility, and
act as a focus for denser development.

Chapter 6 of the LTP discusses Air Quality issues and their importance in the overall aims of the
Transport Strategy. It also sets out objectives and measures for consideration to improve or
“manage” Air Quality. The LTP objectives of Air Quality include:

       Reduce the detrimental effect that traffic has on Air Quality in South East Dorset.
       Reduce the rate of growth of traffic in South East Dorset.
       Encourage alternative and more sustainable forms of travel.
       Encourage reduction in number of journeys taken in congested periods.


3.3      MAPS AND DISTANCES OF RECEPTORS FROM ROADS

The Borough of Poole provided electronic OS LandLine™ which was used in the Geographical
Information System (GIS) used in assessment. Individual buildings or groups of buildings
(receptors) were identified from the electronic OS Landline maps of the areas. The distances of
these receptors from the road, and the widths of the roads, were accurately determined from the
maps.

3.4      ROAD TRAFFIC DATA

This section summarises the information used in this report; more detailed information is given in
Appendix A. Appendix A lists the locations of the traffic flow and speed measurement points, flow
and speed data and other relevant traffic statistics.




                                                                                              netcen   10
                                                                       AEAT/ENV/R/2209/Issue 1


Data were collated from a range of sources, including:

        Data provided by the Transportation Services Department at the Borough of Poole
        Data held in the National Atmospheric Emissions Inventory (NAEI, 2004) - used where no
         other data were available from either The Borough of Poole or the Highways Agency.

Where no average speed data were available, estimated speeds were used near receptors and
junctions. Speeds slower than the national speed limits have been assigned to sections of roads in
areas close to junctions.

3.4.1     Fraction of HGVs
For road links, the percentage of HGVs was calculated from the data held in the 2004 National
Atmospheric Emissions Inventory and from the data supplied by The Borough of Poole.

3.4.2    Base year for traffic
The base year for the traffic flows was 2004.

3.4.3     Traffic growth
Traffic growth figures were based on national growth figures to provide estimates of pollutant
concentrations.

3.4.4    Distance from the centre of the road to the kerbside and to the receptors
Road widths and the distances of receptors from the road were taken from the electronic OS
Landline™ of the Council area.

3.5      PART A AND B PROCESSES

Two new permits have been issued in relation to Part B processes and they both cover the remit for
re-spraying of road vehicles (Westover and Poole Accident Repair). This process is unlikely to
release significant quantity of emissions to air.

There are no other new industrial processes which emit to air.

3.6      AMBIENT MONITORING

3.6.1   Diffusion tubes
The Borough of Poole carries out monitoring for the following air quality pollutants in their area:

       Nitrogen dioxide

       Sulphur dioxide

       Benzene

Nitrogen dioxide is monitored at 17 locations. The tubes are analysed by the Borough‟s
consultants, Casella Stanger. A collocation study was undertaken along with a three-month
continuous monitoring programme at Ashley Road. However, there were only two months of data
available as the diffusion tube was missing during the third month of study, thus there are
insufficient data to support the calculation of a bias adjustment factor.

The sulphur dioxide measurements are made using diffusion tubes and hence cannot be used for
comparison with the Air Quality Objectives.

Full details of the type, locations, and concentrations recorded by the monitors (diffusion tubes) are
given in the relevant chapters.

3.6.2    Continuous monitoring
A three-month continuous monitoring programme was undertaken at Ashley Road between 8 th
November 2005 and 15th February 2006.




                                                                                              netcen   11
                                                                   AEAT/ENV/R/2209/Issue 1


4         Updating and Screening Assessment for
          Carbon Monoxide


4.1       THE NATIONAL PERSPECTIVE

The main source of carbon monoxide in the United Kingdom is road transport, which accounted for
49% of total releases in 2003. Annual emissions of carbon monoxide have been falling steadily
since the 1970s, and are expected to continue to do so. The automatic monitoring network
recorded no exceedences of the objective in 2005 at any location across the UK.


4.2       STANDARD AND OBJECTIVE FOR CARBON MONOXIDE

The Government and the Devolved Administrations originally adopted an 8-hour running mean
concentration of 11.6 mgm-3 as the air quality standard for carbon monoxide. A new objective was
then set at a slightly tighter level of 10 mgm -3 as a running 8-hour mean concentration, to have
been achieved by the end of 2003, bringing it into line with the second Air Quality Daughter
Directive limit value.


4.3       CONCLUSIONS OF THE SECOND ROUND OF REVIEW AND
          ASSESSMENT FOR CARBON MONOXIDE

The following conclusions were given for carbon monoxide in the 2003 Updating and Screening
Assessment for The Borough of Poole.

         Carbon dioxide was not monitored in The Borough of Poole. Data was available for
          Bournemouth and Plymouth. The maximum running 8-hour concentration recorded was
          2.3 mgm-3, which is significantly less than the objective value of 10 mgm -3. There are
          no roads in The Borough of Poole that can be classified as „very busy‟ according to the
          criteria in the guidance.

A detailed assessment was not required for carbon monoxide in The Borough of Poole.


4.4       SCREENING ASSESSMENT OF CARBON MONOXIDE

The Technical Guidance LAQM TG(03) update (January 2006) requires assessment of carbon
monoxide to consider the following sources, data or locations:

         Monitoring Data
         Very Busy Roads or junctions in built-up areas

These are described in the following sections.


4.5       BACKGROUND CONCENTRATIONS FOR CARBON MONOXIDE

The average background carbon monoxide concentration estimated from the UK background maps 7
was 0.32 mgm-3 in 2001 with a maximum concentration of 0.41 mgm -3 south of the A3049,
Wallisdown road. Projected forward to 2006 the background average is 0.21 mgm -3 with a
maximum of 0.26 mgm-3 in the same area.




                                                                                        netcen   12
                                                                      AEAT/ENV/R/2209/Issue 1


4.6      SCREENING ASSESSMENT OF MONITORING DATA

No monitoring has been undertaken for carbon monoxide within The Borough of Poole. Following a
similar approach as carried out in the last USA, the most recent year of data was obtained from the
Air quality Archive for the neighbouring Bournemouth site (98% data capture) and also from
Portsmouth (94% data capture). These sites can be regarded as representative of the southern
south-west. The data is from continuous measurements as part of the AURN network. During
2005 the maximum daily 8-hour mean was recorded as 2.8 mgm-3 at these sites.


4.7      SCREENING ASSESSMENT OF VERY BUSY ROADS

The guidance document LAQM TG(03) requires assessment of CO only at „very busy roads‟, or
junctions in built-up area (Appendix A). In addition to this, the guidance also states that these will
only need to be assessed in areas where the current year background concentration is expected to
be above 1mgm-3.

The maximum background concentration for Poole is 0.26 mgm-3, and based on traffic flow data
supplied by The Borough of Poole and from the NAEI, there are no roads that can be classified as
„very busy‟ according to the criteria in the guidance.


4.8  CONCLUSIONS FOR CARBON MONOXIDE CONCENTRATIONS IN
THE BOROUGH OF POOLE

Carbon dioxide is not monitored in The Borough of Poole. Monitoring data for Bournemouth and
Portsmouth indicate the maximum running 8-hour concentration in 2005 was 2.8 mgm-3, which is
significantly less than the objective value of 10 mgm-3. There are no roads in The Borough of Poole
that can be classified as „very busy‟ according to the criteria in the guidance.

A detailed assessment is not required for carbon monoxide in The Borough of Poole.

5         Updating and Screening Assessment for
          Benzene


5.1       THE NATIONAL PERSPECTIVE

The main sources of benzene emissions in the UK are petrol-engined vehicles, petrol refining,
storage and the distribution and uncontrolled emissions from petrol station forecourts without
vapour recovery systems. A number of policy measures already in place, or planned for future
years, will continue to reduce emissions of benzene. Since January 2000, EU legislation has
reduced the maximum benzene content of petrol to 1%, from a previous upper limit of 5%. The
European Auto-Oil programme will further reduce emissions for cars and light-duty vehicles, and
emissions of benzene from the storage and distribution of petrol are controlled by vapour recovery
systems. The UK automatic monitoring network recorded no exceedences of the 2003 objective in
2003, or later years. Whilst the 2010 objectives are expected to be met at all urban background,
and most roadside locations, there is the possibility for some remaining exceedences, which will
require additional measures at a local level.


5.2       STANDARD AND OBJECTIVE FOR BENZENE

The Government and the Devolved Administrations have adopted a running annual mean
concentration of 16.25 µgm-3 as the air quality standard for benzene, with an objective for the
standard to have been achieved by the end of 2003. However, in light of the health advice from
EPAQS and the Department of Health‟s Committee on Carcinogenicity of Chemicals in Food,
Consumer Products and the Environment (COC) to reduce concentrations of benzene in air to as
low a level as possible, additional tighter objectives have also been set. The additional objective is
for an annual mean of 5 µgm-3 to be achieved by the end of 2010 in England and Wales.


5.3       CONCLUSIONS OF THE SECOND ROUND OF REVIEW AND
          ASSESSMENT FOR BENZENE

The following conclusions were given for benzene in the 2003 Updating and Screening Assessment
for The Borough of Poole.

         There are no roads in The Borough of Poole that can be classified as „very busy‟ according
          to the criteria in the guidance. There are no petrol stations with a throughput greater
          than 2 million litres of petrol and with relevant exposure within 10m of the pumps.

         Emissions data for the Texaco Bulk Fuel Storage facility on the New Harbour road
          indicated that the objectives for 2010 might be exceeded for benzene.           It was
          recommended that the Borough of Poole keep this under review. It also recommended to
          establish a benzene sampling site at the receptor, the data from which could be used to
          provide evidence of compliance with the air quality objectives

A detailed assessment was not required for benzene in The Borough of Poole.

Benzene is monitored at five sites within The Borough of Poole using diffusion tubes and the results
were discussed in the Progress Reports of 2004 and 2005. The results for 2003 and 2004 showed
that The Borough of Poole have met the 2003 objective of 16.25 µgm-3 and were not at risk of
exceedence of the annual mean objective of 5 µgm-3 set for 2010.


5.4       SCREENING ASSESSMENT OF BENZENE

The Technical Guidance LAQM TG(03) Update (January 2006) requires assessment of benzene to
consider the following sources, data or locations:




                                                                                             netcen   14

         Monitoring Data outside an AQMA
         Monitoring Data within an AQMA
         Very Busy Roads or Junctions in Built-up Areas
         New Industrial Sources
         Industrial Sources with substantially increased emissions, or new relevant exposure
         Petrol Stations
         Major Fuel Storage Depots (Petroleum only)

These are described in the following sections.


5.5       BACKGROUND CONCENTRATIONS FOR BENZENE

The average background benzene concentration estimated from the UK background maps7 was
0.47 g m-3 in 2003 with maximum a concentration of 0.70 g m-3 south of the A3049 Wallisdown
Road. Projected forward to 2006 and 2010, the average background concentrations are estimated
to be 0.4 g m-3 and 0.36 g m-3 respectively. The maximum concentration is estimated to fall to
0.54 g m-3 in 2010.


5.6       SCREENING ASSESSMENT OF MONITORING DATA

There are 6 sampling locations for benzene in The Borough of Poole. The measurements are
carried out using diffusion tube techniques and the results for 2005 are shown in table 5.1,
together with predicted concentrations for 2006 and 2010.

factors used for measured roadside data do not apply to measured data where the source is
industrial.

The results indicated taht the air quality objective for benzene is unlikely to be exceeded for 2006
or 2010.


5.7       SCREENING ASSESSMENT OF VERY BUSY ROADS

The guidance document LAQM TG(03) requires assessment of benzene only at „very busy‟ roads, or
junctions in areas where the 2010 background is expected to be above 2 μg m (Appendix A).
                                                                              -3

Traffic flow data supplied by The Borough of Poole and from the NAEI were assessed. Based on
these data, there are no roads in The Borough of Poole that can be classified as „very busy‟
according to the criteria in the guidance.

5.8       SCREENING ASSESSMENT OF INDUSTRIAL SOURCES

The Guidance LAQM TG(03) lists the following processes as significant potential sources of
benzene:




                                                                                           netcen    15
                                                                        AEAT/ENV/R/2209/Issue 1



Part A (percentage of total emissions from all UK plant in this sector to the UK total in brackets)
Petroleum processes (73)
Petrochemical processes (2)
Carbonisation processes (12)
Cement/lime manufacture (7)
Gasification processes (5)

Part B
Processes for the storage and unloading of petrol at terminals

None of the Part A or Part B industrial processes (other than petrol stations or fuel storage facilities
discussed elsewhere) in The Borough of Poole (Appendix B) operate these processes or have the
potential to emit benzene.


5.9      SCREENING ASSESSMENT OF PETROL STATIONS

There are a number of petrol stations in The Borough of Poole authorised as Part B processes
(Appendix B). The guidance requires petrol stations to be considered only if they are near a busy
road where there is relevant exposure within 10 metres of the pumps, and have a throughput
greater than 2 million litres.

Data on annual throughput of petrol was available from one of the larger petrol stations within the
Borough. This is the BP Longfleet Service Station on Longfleet Road and their annual throughput of
petrol between 2003 and 2005 are as follows:

2003 – 4.66 million litres
2004 – 4.50 million litres
2005 – 5.15 million litres

The traffic flow for Longfleet Road is less than 30,000 vehicles per day and there are no relevant
receptors within 10 metres of the petrol pumps.

For other petrol stations where annual throughput data are not available, they have been assessed
whether they are on the busier road (where there are more than 30,000 vehicles per day either in
current year or 2010) and whether there is any exposure to relevant receptors within 10 metres of
the petrol pumps. None of these petrol stations matched both of these criteria and can be
assumed not to have any significant impact on exposure.


5.10     SCREENING ASSESSMENT OF FUEL STORAGE DEPOTS

There is one major fuel storage depot in The Borough of Poole as identified in the 2003 USA and
this is the Texaco depot on New Harbour Road. There has been no new fuel storage depot since
the last USA. The 2003 USA report stated that the 2000 level of benzene emissions from this
depot could exceed the emission threshold for 2010 for the receptors assessed (retail premises on
“The Parade”, 1 High Street). Hence, it was recommended that The Borough of Poole should keep
this under review.

Using the nomogram in figure 3.3 of the guidance document LAQM TG(03) and using the nearest
receptor (as mentioned above) which is 260 m away, the emission threshold for 2003 is 3.43
tonnes per annum for fugitive releases at ground level and 4.94 tonnes per annum for releases at
6 metres height. For 2010, the emission thresholds for releases at 0 m and 6 m height for a
receptor 260 m away are 0.46 and 0.67 tonnes per annum respectively.

The annual petrol throughput of the fuel depot for 2005 as provided by the Borough of Poole was
110 million litres. Using emission factors obtained from the NAEI website, benzene emissions from
the depot is estimated as follows:




                                                                                               netcen   16

    Total estimated emission of benzene                                            0.1130


The estimated benzene emissions for 2005 indicate that the level will meet the 2003 and 2010
emission thresholds for the receptors assessed.


5.11 CONCLUSIONS FOR BENZENE CONCENTRATIONS FOR THE
BOROUGH OF POOLE

There are no roads in The Borough of Poole that can be classified as „very busy‟ according to the
criteria in the guidance. There are also no petrol stations that meet the criteria for assessment.
There is one Bulk Fuel Storage Facility operated by Texaco in Poole and the estimated benzene
emissions for 2005 (based on annual throughput data and emission factors obtained from the NAEI
website) indicated that the level would meet the 2003 and 2010 objectives for benzene.

A detailed assessment is not required for benzene in The Borough of Poole.

6             Updating and Screening Assessment for 1,3-
              Butadiene


6.1           THE NATIONAL PERSPECTIVE

The main source of 1,3-butadiene in the United Kingdom is emissions from motor vehicle exhausts.
1,3-butadiene is also an important industrial chemical and is handled in bulk at a small number of
industrial premises. Maximum running annual mean concentrations of 1,3-butadiene measured at
all urban background/centre and roadside locations in the national network are all well below the
2003 objective of 2.25 µgm-3. The increasing numbers of vehicles equipped with three way
catalysts will significantly reduce emissions of 1,3-butadiene in future years. Recently agreed
further reductions in vehicle emissions and improvements to fuel quality are expected to further
reduce emissions of 1,3-butadiene from vehicle exhausts.


6.2           STANDARD AND OBJECTIVE FOR 1,3-BUTADIENE

The Government and the Devolved Administrations adopted a maximum running annual mean
concentration of 2.25 µgm-3 as an air quality standard for 1,3-butadiene. The objective is for the
standard to have been achieved by the end of 2003.


6.3  CONCLUSIONS OF THE SECOND ROUND OF REVIEW AND
ASSESSMENT FOR 1,3-BUTADIENE

The following conclusions were given for 1,3-butadiene in the 2003 Updating and Screening
Assessment for The Borough of Poole

             Estimated background concentrations and data from national monitoring stations indicate
              that the objective for 1,3-butadiene is likely to be achieved by the end of 2003. There are
              no industrial processes, current or proposed, in The Borough of Poole, which have the
              potential to emit 1,3-butadiene.

A detailed assessment was not required for 1,3-butadiene in The Borough of Poole.


6.4           SCREENING ASSESSMENT OF 1,3-BUTADIENE

The Technical Guidance LAQM TG(03) Update (January 2006) requires assessment of 1,3-
butadiene to consider the following sources, data or locations:

              Monitoring data
              New industrial sources
              Industrial sources with substantially increased emissions, or new relevant exposure

These are described in the following sections.

6.5           BACKGROUND CONCENTRATIONS FOR 1,3-BUTADIENE

The average background 1,3-butadiene concentration estimated from the UK background maps7
was 0.16 gm-3 in 2003 with a maximum concentration of 0.23 gm-3 south of the A3049
Wallisdown Road. Projected forward to 2006, the average background concentration is 0.12 gm-3
with a maximum of 0.17 gm-3 in the same area.




                                                                                                netcen   19
                                                                      AEAT/ENV/R/2209/Issue 1


6.6      SCREENING ASSESSMENT OF MONITORING DATA

No monitoring of 1,3-butadiene has been undertaken in The Borough of Poole. There is a roadside
monitoring station at London Marylebone Road. The 2005 annual mean measured at this station
was 0.45 gm-3 which is below the 2003 running annual mean objective value for England and
Wales of 2.25 gm-3.

6.7      SCREENING ASSESSMENT OF INDUSTRIAL SOURCES

The Guidance LAQM TG(03)1 lists the following processes as significant potential sources of 1,3-
butadiene:

Part A (percentage of total emissions from all UK plant in this sector to the UK total in brackets)
Petroleum processes (2)
Petrochemical processes (95)
Organic chemical manufacture (3)

Part B
Rubber processes

There are no Part A or Part B processes in the Borough of Poole (Appendix B) that operate these
processes. There has been no change to this position.


6.8  CONCLUSIONS FOR 1,3-BUTADIENE CONCENTRATIONS IN THE
BOROUGH OF POOLE

Estimated background concentrations and data from national monitoring stations indicate that the
2003 objective for 1,3-butadiene is likely to be achieved for the current year. There are no
industrial processes, current or proposed, in The Borough of Poole, which have the potential to
emit 1,3-butadiene.

A detailed assessment is not required for 1,3-butadiene in The Borough of Poole.

7             Updating and Screening Assessment for Lead


7.1           THE NATIONAL PERSPECTIVE

The agreement reached between the European Parliament and the Environment Council on the
Directive on the Quality of Petrol and Diesel Fuels (part of the Auto-Oil Programme) led to the ban
on sales of leaded petrol in the United Kingdom with effect from 1 January 2000. Emissions of lead
are now restricted to a variety of industrial activities, such as battery manufacture, pigments in
paints and glazes, alloys, radiation shielding, tank lining and piping.

Detailed assessments of the potential impact of lead emissions from industrial processes have been
undertaken by the Government and the Devolved Administrations, based upon both monitoring and
sector analysis studies. The former has included a 12-month monitoring survey in the vicinity of 30
key industrial sites in the UK, which has been used to supplement information already provided
from the non-automatic monitoring networks. These monitoring data have generally indicated no
exceedences of the 2004 or 2008 objectives, although locations in proximity to non-ferrous metal
production and foundry processes were deemed to be at risk.


7.2           STANDARD AND OBJECTIVE FOR LEAD

The Government and the Devolved Administrations adopted an annual mean concentration of
0.5 µgm-3 as the air quality standard for lead, with an objective for the standard to have been
achieved by the end of 2004. In addition, a lower air quality objective of 0.25 µgm -3 has also been
set to be achieved by the end of 2008.


7.3  CONCLUSIONS OF THE SECOND ROUND OF REVIEW AND
ASSESSMENT FOR LEAD

The following conclusions were given for lead in the 2003 Updating and Screening Assessment for
The Borough of Poole.

             Emissions of lead from industrial processes in The Borough of Poole are not likely to
              exceed the objectives for lead to be achieved in 2004 and 2008.

A detailed assessment was not required for lead in The Borough of Poole.


7.4           SCREENING ASSESSMENT OF LEAD

The Technical Guidance LAQM TG(03) Update (January 2006)1 requires assessment of lead to
consider the following sources, data or locations:

              Monitoring data
              New industrial sources
              Industrial sources with substantially increased emissions, or new relevant exposure

These are described in the following sections.


7.5           SCREENING ASSESSMENT OF MONITORING DATA

No monitoring of lead has been undertaken in The Borough of Poole. There are a number of
different monitoring networks sponsored by Defra that can be broken down into four categories:
Towns (multi-element and statutory sites), lead at petrol station sites, industrial (around known
point sources) and rural. These data are summaries in table 7.1 below for 2004.




                                                                                               netcen   21

      From these data it can be seen that even at the EC lead directive sites the objectives are unlikely
      to be exceeded for 2004 or 2008.


7.6   SCREENING ASSESSMENT OF INDUSTRIAL SOURCES

      The Guidance LAQM TG(03) lists the following processes as significant potential sources of lead:

      Part A (percentage of total emissions from all UK plant in this sector to the UK total in brackets)
      Iron and steel (37)
      Non-ferrous metals (23)
      Manufacture of organic chemicals (35)

      Part B
      Non-ferrous metal furnaces
      Electrical furnaces
      Blast cupolas
      Aluminium processes
      Zinc Processes
      Copper processes
      Lead glass manufacture


      The 2003 USA report highlighted that there is one Part A process (Sigma-Aldrich) listed as process
      that manufacturers or uses organic chemicals and they are not currently required to monitor
      releases of lead from the process. The Environment Agency has undertaken to ensure that Part A




                                                                                                   netcen   22
                                                                             AEAT/ENV/R/2209/Issue 1


      processes do not emit so as to lead to breaches of the UK air quality objectives. It is therefore
      considered that this process is unlikely to lead to exceedences of the air quality objectives for lead.
      There has been no new Part A process, which have the potential to emit lead.

      None of the Part B industrial processes in The Borough of Poole (Appendix B) operate these
      processes or have the potential to emit lead. There has been no change to this position.


7.7   CONCLUSIONS FOR LEAD CONCENTRATIONS IN THE BOROUGH OF
      POOLE

      Emissions of lead from industrial processes in The Borough of Poole are not likely to exceed the
      objectives for lead to be achieved in 2004 and 2008.

      A detailed assessment is not required for lead in The Borough of Poole.

8         Updating and Screening Assessment for
          Nitrogen Dioxide


8.1       INTRODUCTION

The principal source of NOx emissions is road transport, which accounted for about 40% of total UK
emissions in 2003. Major roads carrying large volumes of high-speed traffic (such as motorways
and other primary routes) are a predominant source, as are conurbations and city centres with
congested traffic. Within most urban areas, the contribution of road transport to local emissions will
be much greater than for the national picture.

Meeting the annual mean objective for 2005, and the corresponding limit value in 2010, is
considerably more demanding than achieving the 1-hour objective. By 2005, the annual mean
objective was being achieved at all urban background locations outside of London, but being
exceeded more widely at roadside sites throughout the UK in close proximity to busy road links.
Projections for 2010 indicate that the EU limit value may still be exceeded at urban background
sites in inner London, and at roadside locations in other cities.


8.2       STANDARDS AND OBJECTIVES FOR NITROGEN DIOXIDE

The Government and the Devolved Administrations have adopted two Air Quality Objectives for
nitrogen dioxide, as an annual mean concentration of 40 µgm -3, and a 1-hour mean concentration
of 200 µg m-3 not to be exceeded more than 18 times per year. The objectives were to be achieved
by the end of 2005.


8.3  CONCLUSIONS OF THE SECOND ROUND OF REVIEW AND
ASSESSMENT FOR NITROGEN DIOXIDE

The following conclusions were given for nitrogen dioxide in the second round of review and
assessment for The Borough of Poole:

         Diffusion tube results for 2003 and 2004 (as reported in the Progress Report of 2004 and
          2005) showed exceedences of the annual mean objective for NO2 at four locations: Ashley
          Road, Commercial Road, Poole Road and at the Mountbatten Roundabout.

         A Detailed Assessment (2005) was undertaken at the four locations mentioned above
          which involved the use of dispersion modelling techniques. The results of the assessment
          showed that the 2005 objectives for NO2 would be met at the locations assessed in Poole
          Road and Commercial Road. However, it was considered possible that there would be
          exceedences of the objectives at some locations on the southern side of Ashley Road and
          at properties in the vicinity of the Mountbatten Arms roundabout.

The Detailed Assessment report recommended that The Borough of Poole should consider declaring
an AQMA if relevant exposure is confirmed to occur at Ashley Road and at the Mountbatten Arms
roundabout where exceedences of the objective have been predicted.

Based on the findings of the Detailed Assessment, the Borough have decided not to declare an
AQMA at this stage for the following reasons:

         Both assessments at Ashley Road and Mountbatten Roundabout were based purely on
          diffusion tube monitoring and modelling techniques to predict the 2005 and 2010
          concentration of nitrogen dioxide, no real time monitoring had yet been undertaken at
          these locations.




                                                                                             netcen   24
                                                                          AEAT/ENV/R/2209/Issue 1


             Results for Ashley Road were only marginally above the 2005 annual average objective
              for NO2 and for the Mountbatten Roundabout, there is no relevant exposure where the
              diffusion tube was located.

The Borough of Poole have sought permission from Defra to pursue further monitoring at these
locations to confirm the likelihood of exceedence. Such an approach is in accordance with LAQM.
TG(03) paragraph 1.2.3 which states:

“Where uncertainties are potentially high and the outcomes is marginal, then the authority should
look to obtaining more reliable data to improve the confidence in its decision”

Defra has accepted the request from The Borough of Poole to carry out further investigation at
these two locations. This would involve undertaking a 3-month continuous monitoring programme
at Ashley Road and relocation of the diffusion site to relevant exposure at Mountbatten
Roundabout.


8.4           SCREENING ASSESSMENT OF NITROGEN DIOXIDE
                                                                    1
The Technical Guidance LAQM TG(03) Update (January 2006)                requires assessment of nitrogen
dioxide to consider the following sources, data or locations:

              Monitoring data outside an AQMA
              Monitoring data within an AQMA
              Narrow congested streets with residential properties close to the kerb
              Junctions
              Busy streets where people may spend 1-hour or more close to traffic
              Roads with high flow of buses and/or HGVs
              New roads constructed or proposed since previous round of review and assessment
              Roads with significantly changed traffic flows, or new relevant exposure
              Bus Stations
              New industrial sources
              Industrial sources with substantially increased emissions, or new relevant exposure
              Aircraft

These are evaluated in the following sections.


8.5           BACKGROUND CONCENTRATIONS FOR NITROGEN DIOXIDE

The estimated average background nitrogen dioxide concentration for the Borough of Poole was
16.2 gm-3 in 2005 with a maximum concentration of 22.2 μgm -3 north of the A3049 Dorset Way.
For 2010, the average background concentration is estimated to be 14.0μgm -3 with a maximum of
20.1 μgm-3.


8.6           SCREENING ASSESSMENT OF MONITORING DATA

8.6.1    Automatic Monitoring
A three-month continuous monitoring programme using a chemiluminescence analyser was
undertaken at Ashely Road between 8th November 2005 and 15th February 2006. Ashley Road was
subjected to a detailed assessment in June 2005 and a continuous monitor was set up here to
pursue further clarification of the likelihood of exceedence of the national objective. The monitor
was located at a roadside location, approximately 4.5 meters from the kerb (OS Grid Reference
404328, 92153).

Table 8.2 shows the measured concentrations during the three-month period. From the period
mean (8/11/05-15/2/06) an estimate has been made of the likely annual average value for the
whole of 2005, based on the relationship between the same 2005 period mean, and the 2005
annual mean at 4 surrounding AURN national network automatic monitoring sites: Bournemouth,
Brighton Preston Park, Portsmouth and Reading New Town (Table 8.1).

The three-month monitoring results of the automatic monitoring show that the levels were below
the objective mean of 40μgm-3.

8.6.2    Diffusion tube monitoring
Nitrogen dioxide is measured at 17 sites within the Borough of Poole (Appendix D). Nitrogen
dioxide concentrations measured for 2005 and estimated concentrations for 2006 and 2010 are
presented in table 8.3 below. The revised NO2 adjustment factors to future years were obtained
from the LAQM website and they are shown in Table 8.4. Diffusion tubes that have less than 9
months results are not projected forward to future years.

Diffusion tube results for 2005 show that six sites within the Borough of Poole exceeded the annual
mean objective for NO2 and they are discussed as follows:

       Poole Road and Commercial Road – These two locations were subjected to detailed
        assessments in June 2005 and modelling results showed that they would meet the mean
        objective for NO2. High concentrations measured at these locations are due to its kerbside
        locations and restricted flow of air around the diffusion tube. The Borough of Poole has
        decided to relocate the diffusion tube at Poole Road but there is no current plan for the
        relocation of the diffusion tube at Commercial Road.

       Ashley Road – this was the subject of consideration of declaring an AQMA following the
        conclusion of a detailed assessment. As a result, further monitoring was pursued here to
        confirm decision. The three-month continuous monitoring results indicated that the level
        was below the annual mean objective for NO2 (Table 8.2). It is considered that the
        continuous monitoring results are more representative as the continuous monitor was
        situated at a roadside location while the diffusion tube was located at a kerbside location.
        In addition, an updated dispersion modelling assessment16 was made at this location in
        April 2006 and the continuous monitoring data was used to verify the model. The results
        showed that whilst it is likely that annual average NO2 concentrations are close to
        exceedence along the southern side of Ashley Road in 2005, there are no areas of
        exceedence at locations where the objective would apply, i.e. no relevant receptors.
        Therefore, there is currently no need for the Borough of Poole to declare an AQMA at this
        location. However, it is recommended that the Borough of Poole keep this location under
        review in the next progress report.

       Mountbatten Roundabout – this was the subject of consideration of declaring an AQMA
        following the conclusion of a detailed assessment. Diffusion tube at this site was relocated
        to Dolberry Road South (in September 2005) where relevant exposure exists. The results
        collected to date have shown that the concentrations for NO2 are below the objective. It is
        recommended that a longer period of observation be made at this location and to report
        the results in the next Progress Report.

       Longfleet Road and Pottery Junction – these are new locations where a risk of
        exceedence of the annual mean objective for NO2 is identified. Hence, these two locations
        are assessed in terms of the relevant exposure and the results are shown in table 8.5
        below. The distance between the diffusion tube and the nearest building façade is
        measured from the OS Ordnance Landline Map. Scaling factors were obtained from the
        UWE website to adjust kerbside monitoring results to relevant exposure results:

                 2 – 5 metres (0.95)
                 5 – 10 metres (0.90)
                 10 – 20 metres (0.75)

The results indicate that in relation to relevant exposure, Pottery Junction is likely to meet the
objectives at the nearest building façade for both current and future years. At Longfleet Road,
concentrations at the nearest building façade for current year have just reached the threshold limit,




                                                                                            netcen   27
                                                                   AEAT/ENV/R/2209/Issue 1


but it is estimated to drop below the objective mean by 2010. It is recommended that The
Borough of Poole relocate the diffusion tube site at Longfleet Road to the nearest building façade
where relevant public exposure exists, and report the findings in the next progress report.

8.6.3    Bias correction of diffusion tube data
A co-location study was undertaken along with the three-month continuous monitoring programme
at Ashley Road. Unfortunately, the diffusion tubes were missing during the third month of the
monitoring programme, hence there are only two months of data available which is insufficient to
obtain a bias correction factor.

The diffusion tubes are prepared and analysed by Casella Stanger using the 50% TEA in acetone
method. Information regarding the typical bias factor of these diffusion tubes was sought for year
2005 from the database of co-location studies by UWE on behalf of DEFRA (UWE, 2006) and the
averaged bias factors derived from seven co-location studies is 1.18. This bias factor has been
used to adjust the results as shown in Table 8.3.


8.7      SCREENING ASSESSMENT OF ROAD TRAFFIC SOURCES

8.7.1    Main Roads

Traffic flow data were taken from the NAEI 2004 roads database and from traffic count data for
roads in Poole for 2004 supplied by The Borough of Poole (Appendix A). For screening purposes, a
receptor distance of 5 meters and annual average speeds for the road (as provided in the NAEI
database) were used for each count point in the NAEI 2004 roads database . A lower speed of 20
kph has also been used to estimate the effect of potential congestion. A traffic growth factor of
1.017 to 2005, 1.035 to 2006 and 1.097 to 2010 was used.

Table 8.6 and 8.7 shows nitrogen dioxide concentrations in 2006 and 2010 calculated using DMRB
for A roads in The Borough of Poole.

The DMRB screening model indicates that the 2005 objective and 2010 limit value for the annual
mean for NO2 is unlikely to be exceeded at receptors near A roads in The Borough of Poole.

The following items from the checklist for NO2 have also been considered:
    Narrow congested streets with residential properties close to the kerb: None were
        identified in the 2003 USA and there has been no change to this position.

      Busy streets where people may spend more than one hour close to traffic: None
       were identified in the 2003 USA and there has been no change to this position.

      Roads with high flow of buses and/or HGVs: There are no roads within The Borough
       of Poole with a high proportion (>25%) of HGVs.




                                                                                      netcen   32
                                                                      AEAT/ENV/R/2209/Issue 1


       New roads constructed or proposed since previous round of review & assessment:
        No new roads have been constructed or proposed since the second round of review &
        assessment.

       Roads with significantly changed traffic flows, or new relevant exposure: There
        are no roads that have experienced large (>25%) increases in traffic. A new diffusion tube
        site was set up at Herbert Avenue in 2005 (as mentioned in Progress Report 2005). This
        road is identified to have high volume of traffic and relative exposure may exist to
        residents. Both diffusion tube and DMRB results show that the objective will be met at this
        road.

       Busy junctions: This was examined in the 2003 USA and six busy junctions with potential
        to have relevant exposure within 20 metres were identified (Appendix A, Table A.5).
        Annual average NO2 concentrations near these selected road junctions have been
        estimated for 2005 and 2010 using DMRB and the results showed that the annual mean
        objective for NO2 is unlikely to be exceeded in these years. There has been no significant
        change in the traffic flow since the last USA hence these junctions are not reassessed.
        There are no new busy junctions with relevant exposure identified.


8.8      SCREENING ASSESSMENT OF INDUSTRIAL SOURCES

The Guidance LAQM TG(03)1 lists the following processes as significant potential sources of
nitrogen dioxide:

Part A (percentage of total emissions from all UK plant in this sector to the UK total in brackets)
Iron and steel (19)
Petroleum processes (16)
Combustion processes (34)
Cement/lime manufacture (9)
Carbonisation (6)
Gasification (4)
Inorganic chemicals (4)

Part B
Glass manufacture

None of the Part A or Part B industrial processes in The Borough of Poole (Appendix B) operate
these processes or have the potential to emit significant quantities of NO2.


8.9      SCREENING ASSESSMENT OF OTHER TRANSPORT SOURCES

8.9.1     Bus Stations
This was examined in the 2003 USA. The main bus station in The Borough of Poole is situated at
the Dolphin Centre on Kingland Road and it was estimated to have 1540 bus movement per day.
Using DMRB model, annual average NO2 concentrations at the bus station have been estimated for
2005 and 2010. The results show that it is unlikely that the air quality objective will be exceeded
in 2005 or 2010 at the bus station. According to the information provided by The Borough of Poole
for this assessment, there are 1453 bus movements to and from Poole bus station on a typical
weekday, which is less than the amount as assessed in the last USA hence it is likely that the
objective for 2005 and 2010 will be met at this bus station.

8.9.2     Airports
There are no airports in The Borough of Poole or neighbouring authorities that have a throughput
of 5 million passengers per year and/or 500,000 tonnes of freight. There has been no change to
this position.

8.10 CONCLUSIONS FOR NITROGEN DIOXIDE CONCENTRATIONS IN
THE BOROUGH OF POOLE

The monitoring results for 2005 show that six sites within The Borough of Poole exceeded the
annual mean objective of 40 μgm-3 for NO2. These locations are in Longfleet Road, Poole Road,
Ashley Road, Commercial Road, Mountbatten Roundabout and Pottery Junction.

Four of the exceeding locations namely Poole road, Commercial Road, Mountbatten Roundabout
and Ashley Road were subjected to detailed assessment in June 2005. The results of the detailed
assessment have shown that Poole Road and Commercial Road would meet the objective limit of
40 μgm-3. The reason for high concentration measured at Poole Road and Commercial Road are
due to its kerbside location. The Borough of Poole has decided to relocate the Poole Road diffusion
tube to the other side of the road where it is not positioned near the pedestrian crossing or building
which would restrict the flow of air around the diffusion tube. There is no current plan for the
relocation of the diffusion tube at Commercial Road.

Further investigation was pursued at Ashley Road and Mountbatten Roundabout to confirm whether
there is a requirement for the declaration of AQMAs. Three-month continuous monitoring results at
Ashley Road indicated that the level was below the annual mean objective for NO 2. In addition, an
updated dispersion modelling assessment16 was made at this location and the continuous
monitoring data was used to verify the model. The results showed that whilst it is likely that
annual average NO2 concentrations are close to exceedence along the southern side of Ashley Road
in 2005, there are no areas of exceedence at locations where the objective would apply, i.e. at
relevant receptors.

Diffusion tube monitoring at Mountbatten Roundabout was relocated to Dolberry Road South where
relevant exposure exists. The results collected to date have shown that the average NO 2
concentration is well below the objective mean for NO2 at this location. Based on these findings,
there is currently no need for the Borough of Poole to declare an AQMA at either Ashley Road or
areas in the vicinity of the Mountbatten Roundabout.      However, it is recommended that The
Borough of Poole keep both of these locations under review and report findings in the next
Progress Report.

Longfleet Road and Pottery Junction are new locations where a risk of exceedence of the annual
mean objective for NO2 is identified. These two locations are assessed in term of the relevant
exposure and the results show that both locations will meet the objectives at the nearest building
façade for 2006 and 2010.

A detailed assessment is not required for nitrogen dioxide.

9         Updating and Screening Assessment for
          Sulphur Dioxide


9.1       INTRODUCTION

The main source of sulphur dioxide in the United Kingdom is power stations, which accounted for
69% of emissions in 2004. There are also significant emissions from other industrial combustion
sources. Emissions from domestic sources fell by 34% in 2002-2003, but these can still have a
significant effect locally. Road transport currently accounts for less than 1% of emissions.

Local exceedences of the objectives (principally the 15-minute mean objective) may occur in the
vicinity of small combustion plant (less than 20 MW), which burn coal or oil, in areas where solid
fuels are the predominant form of domestic heating, and in the vicinity of major ports.


9.2       STANDARD AND OBJECTIVE FOR SULPHUR DIOXIDE

The Government and the Devolved Administrations have adopted a 15-minute mean of 266 µgm-3
as an air quality standard for sulphur dioxide, with an objective for the standard not to be
exceeded more than 35 times in a year by the end of 2005.

Additional objectives have also been set which are equivalent to the EU limit values specified in the
First Air Quality Daughter Directive. These are for a 1-hour mean objective of 350 µgm-3, to be
exceeded no more than 24 times per year, and a 24-hour objective of 125 µgm-3, to be exceeded
no more than 3 times per year, to be achieved by the end of 2004.


9.3  CONCLUSIONS OF THE FIRST ROUND OF REVIEW AND
ASSESSMENT FOR SULPHUR DIOXIDE

The following conclusions were given for SO2 in the 2003 Updating and Screening Assessment for
The Borough of Poole

       There were no significant industrial or domestic sources of sulphur dioxide in Poole and
        that a detailed assessment was not required.

Progress Report (2004) and Progress Report (2005)

       Monitoring of sulphur dioxide has been undertaken within The Borough of Poole since
        1995. Although this long term monitoring results are not comparable to any short term
        objectives for sulphur dioxide, the risk of exceeding air quality objectives for sulphur
        dioxide is unlikely. It remains the case that there are no significant industrial or domestic
        sources of sulphur dioxide.


9.4       SCREENING ASSESSMENT OF SULPHUR DIOXIDE

The Technical Guidance LAQM TG(03) Update (January, 2006) requires assessment of sulphur
dioxide to consider the following sources, data or locations:

          Monitoring data outside an AQMA
          Monitoring data within an AQMA
          New industrial sources
          Industrial sources with substantially increased emissions, or new relevant exposure
          Areas of domestic coal burning

9.5         BACKGROUND CONCENTRATIONS FOR SULPHUR DIOXIDE

The estimated average background sulphur dioxide concentration for 2001 was 2.5 gm-3 with a
maximum concentration of 6.6 gm-3 south-east of Merley.


9.6         SCREENING ASSESSMENT OF MONITORING DATA

Sulphur dioxide is monitored at four locations within the Borough of Poole using diffusion tubes.
This long term monitoring technique does not produce results that can be used for comparison with
the short-term air quality objectives.


9.7         SCREENING ASSESSMENT OF INDUSTRIAL SOURCES

The Guidance LAQM TG(03)1 lists the following processes as significant potential sources of sulphur
dioxide:

Part A (percentage of total emissions from all UK plant in this sector to the UK total in brackets)
Iron and steel (9)
Petroleum processes (15)
Combustion processes (45)
Cement/lime manufacture (3)
Carbonisation (10)
Non-ferrous metals (7)
Ceramic Production (9)

Part B
Combustion plant 20-50 mwth
Furnaces 20-50 mwth
Copper processes
Refractory goods
Glass manufacture
Roadstone coating

None of the Part A or Part B industrial processes in The Borough of Poole (Appendix B) operate
these processes or have the potential to emit significant quantities of sulphur dioxide. There has
been no change to this position.

9.7.1       Small Boilers

There are a number of waste oil burners contained in the Part B list and they are all listed as being
less than 0.4 MW. There are no other boilers greater than 5MW identified in Poole.


9.8         SCREENING ASSESSMENT OF DOMESTIC SOURCES

9.8.1       Domestic coal burning

There are no direct data for domestic coal burning available. In the 2003 USA report, the density
of coal burning households were estimated based on population, average household area and an
assumption of 5% of household using coal as primary source of fuel. The results showed that the
density of coal burning households is unlikely to be more than 100 houses within 500 m2 of an
averaged or most densely populated area of Poole. In addition, fuel use statistics in the NAEI




                                                                                             netcen   37
                                                                      AEAT/ENV/R/2209/Issue 1


database for 2000 (the estimated amount of fuel burned on a 1km by 1km grid throughout Poole)
indicated that the proportion of coal use within Poole accounted for only 2%.

Domestic coal burning is therefore unlikely to put the air quality objective at risk of exceedence.
There have been no change to this position and no significant areas of domestic coal burning have
been identified.


9.9      SCREENING ASSESSMENT OF OTHER TRANSPORT SOURCES

9.9.1    Shipping
The total vessel calls for all ferries and general cargo at Poole Harbour during 2005 were 1,976
hence there were about 3952 shipping movements. This is less than the 5000 movements
requiring a detailed assessment to be undertaken and shipping is not considered a significant
source of sulphur dioxide.

9.9.2    Railways

According to information supplied by The Borough of Poole, there are no passenger diesel trains
stopping at Poole, but there is one freight service runs to Oasis Plant on Dawkins Road.

The service runs as one train per day for between 3 and 5 days a week, depending upon the
demand for stone by the construction industry. The freight train arrives at Hamworthy station at
lunch time and it usually stops briefly at one end of the platform to allow the driver to visit the
signal before it proceeds down the branch to start unloading.

The empty return service has a path booked departing Poole just after 17:30. Where the train
waits depends on how fast the wagons are unloaded on the branch. Under normal circumstances
the unloaded train will wait for its allocated main line path on the branch at Hamworthy station
where it would stand just over a subway. If the train is unloaded quickly, it will wait on the branch
for a path down to Poole and then wait in the carriage sidings at Poole, alongside the footpath
behind Poole High School, for its allocated path towards Southampton. From observation, the
latter circumstance estimated to happen about once a fortnight (but it can be variable).

The length of stay when the train departs from the Hamworthy Station in the evening is variable.
However, it is noticed that the train is frequently stationary for more than 15 minutes. Within 15
metres of the locomotive, there is a potential for exposure of members of the public for periods of
15 minutes or more, namely the back gardens of no.83 to 93 Galloway Road.

When the return train waits in the carriage sidings at Poole (the second circumstance as mentioned
above), there is much less potential for exposure, the closest point of contact is well above 15
metres.

Based on the information described above, it is considered that there are no more than two
occasions a day when there might be a locomotive stationary with its engine running for 15
minutes or more. Hence, it is concluded that a detailed assessment for SO 2 is not required at this
stage provided that there are no more than two occasions a day when this freight train has its
engine running for more than 15 minutes or at one occasion a day with the engine running
significantly more than 15 minutes.

However, it is recommended that The Borough of Poole undertake a survey at the Hamworthy
Station to investigate the typical duration and frequency of the freight train with its engine running
for 15 minutes or more.


9.10     CONCLUSIONS FOR SULPHUR DIOXIDE CONCENTRATIONS THE
         BOROUGH OF POOLE

According to the information provided by The Borough of Poole, it is observed that there is one
diesel freight train regularly stationary with its engine running for 15 minutes or more at the




                                                                                             netcen   38

Hamworthy Station on its return journey, and there is relevant exposure within 15 metres of the
train. However, as it is only observed to happen at most on one occasion per day thus a detailed
assessment is not required at this stage. It is recommended that The Borough of Poole carry out a
survey at Hamworthy to confirm the typical duration and frequency of this freight train being
stationary with its engine running at the station.

There are no significant industrial or domestic sources of sulphur dioxide in The Borough of Poole.

A detailed assessment is not required for sulphur dioxide.

10       Updating and Screening Assessment for PM10


10.1     THE NATIONAL PERSPECTIVE

National UK emissions of primary PM10 have been estimated as totalling 141,000 tonnes in 2003. Of
this total, around 27% was derived from road transport sources. It should be noted that, in
general, the emissions estimates for PM10 are less accurate than those for the other pollutants with
prescribed objectives, especially for sources other than road transport.

The Government established the Airborne Particles Expert Group (APEG) to advise on sources of
PM10 in the UK and current and future ambient concentrations. Their conclusions were published in
January 1999 (APEG, 1999). APEG concluded that a significant proportion of the current annual
average PM10 is due to the secondary formation of particulate sulphates and nitrates, resulting
from the oxidation of sulphur and nitrogen oxides. These are regional scale pollutants and the
annual concentrations do not vary greatly over a scale of tens of kilometres. There are also natural
or semi-natural sources such as wind-blown dust and sea salt particles. The impact of local urban
sources is superimposed on this regional background. Such local sources are generally responsible
for winter episodes of hourly mean concentrations of PM10 above 100 g m-3 associated with poor
dispersion. However, it is clear that many of the sources of PM 10 are outside the control of
individual local authorities and the estimation of future concentrations of PM 10 are in part
dependent on predictions of the secondary particle component.


10.2     STANDARD AND OBJECTIVE FOR PM10

The Government and the Devolved Administrations adopted two Air Quality Objectives for fine
particles (PM10), which are equivalent to the EU Stage 1 limit values in the first Air Quality
Daughter Directive. The objectives are 40 µgm-3 as the annual mean, and 50 µgm-3 as the fixed
24-hour mean to be exceeded on no more than 35 days per year, to have been achieved by the
end of 2004. In addition there is an objective of 50 µgm-3 as the fixed 24-hour mean to be
exceeded on no more than 7 days per year and 20 µgm -3 as the annual mean to be achieved by
the end of 2010. The objectives are based upon measurements carried out using the European
gravimetric transfer reference sampler or equivalent.

It should be noted that the objectives for 2010, based on the Stage 2 EU Limit Values have not
been included in the Air Quality Regulations for England, and local authorities are not currently
required to assess against them. In addition, they were the subject of the European Commission‟s
recent review of the First Daughter Directive.

The Commission is currently consulting on a new consolidated Directive on Ambient Air Quality,
which is likely to see changes to the above Limit Values, though the nature of these changes
cannot be confirmed at this time.


10.3 CONCLUSIONS OF THE SECOND ROUND OF REVIEW AND
ASSESSMENT FOR PM10

The following conclusions were given for PM10 in the 2003 Updating and Screening Assessment:

        The Borough of Poole has a high background concentration of PM10, from other work8,9 it
         can be considered that due to the location of the area a minimum contribution of sea-salt
         could be between 1 and 2 μg.m-3 of the annual mean concentration and during some
         periods as much as 35% of the annual mean.

        The objectives are unlikely to be exceeded in 2004. However, due in most part to the
         high background concentration the objectives for 2010 may be exceeded in that year,
         especially near busy roads and junctions.




                                                                                           netcen   40
                                                                      AEAT/ENV/R/2209/Issue 1


           Using data derived from other similar areas and specifically using data from the
            neighbouring Local Authority, Bournemouth, as indicative of the area as a whole there is
            unlikely to be an exceedence of the air quality objectives for 2005.

A detailed assessment is not required for PM10 in The Borough of Poole.

10.4        SCREENING ASSESSMENT OF PM10

The Technical Guidance LAQM TG(03) Update (January 2006) requires assessment of PM 10 to
consider the following sources, data or locations:

            Monitoring data outside and within an AQMA
            Junctions
            Roads with high flow of buses and/or HGVs
            New roads constructed or proposed since last round of review and assessment
            Roads with significantly changed traffic flows or new relevant exposure
            Roads close to the objective during the second round of review and assessment
            New industrial sources
            Industrial sources with substantially increased emissions or new relevant exposure
            Areas with domestic solid fuel burning
            Quarries, landfill sites, opencast coal, handling of dusty cargoes at ports etc
            Aircraft

These are evaluated in the following sections.


10.5        BACKGROUND CONCENTRATIONS FOR PM10

The estimated average background PM10 concentration for The Borough of Poole was 20.5 g.m-3 in
2004 with a maximum concentration of 23.5 g.m-3. The concentration range is fairly constant in
the area (ranging from 17.8 to 23.5 gm-3). The estimated average background concentrations for
2005 and 2010 are 20.4 μgm-3 and 18.9 μgm-3 respectively, with a maximum concentration of 23.5
μgm-3 for 2005 and 21.9 μgm-3 for 2010.


10.6        SCREENING ASSESSMENT OF MONITORING DATA

No monitoring for PM10 has been undertaken within The Borough of Poole. Data from the Air
Quality Archive for neighbouring Bournemouth was obtained for 2005. The annual mean of daily
measured PM10 measured at this urban background site was 25 μgm-3.


10.7        SCREENING ASSESSMENT OF ROAD TRAFFIC SOURCES

10.7.1      Main Roads

Traffic flow data were taken from the NAEI 2004 roads database and from traffic count data
supplied by the Borough of Poole (Appendix A). For screening purposes, a receptor distance of 5
meters has been used to illustrate the possible worst case roadside pollutant concentrations and
the average speeds for the road (as provided from the NAEI database) were used. Traffic growth
factors of 1.017 to 2005, 1.035 to 2006 and 1.097 to 2010 were used. In addition there is an
additional column to detail the effect of traffic moving at 20 kph rather than at the average speed
given in the NAEI roads database for 2004.

Table 10.2 and 10.3 shows PM10 concentrations in 2006 and 2010 calculated using DMRB for A
roads and motorways in The Borough of Poole.

The DMRB screening model indicates that the 2004 objectives for PM10 are unlikely to be exceeded
at receptors near A roads in The Borough of Poole. However, the results indicate that meeting the
2010 objectives is likely to be a challenge.

The following items from the checklist for PM10 have also been considered:
       Roads with high flow of buses and/or HGVs: There are no roads with high proportion
          (>20%) of HGVs within the Borough.




                                                                                        netcen   45
                                                                      AEAT/ENV/R/2209/Issue 1


       New roads constructed or proposed since last round of Review and Assessment:
        there are no new roads constructed or proposed since the last round of review and
        assessment.

       Roads with significantly changed traffic flows, or new relevant exposure: There
        are no roads that have experienced large (>25%) increases in traffic since the last USA.

       Roads close to the objective during the second round of Review and Assessment:
        There were no roads close to the 2004 objective (where between 25 and 35 days
        exceedences of the 24 hour objective were predicted) during the second round of Review
        and Assessment.

       Busy junctions: This was examined in the 2003 USA and annual average concentrations
        for PM10 near six busy road junctions (Appendix A, Table A.5) in the Borough of Poole
        have been estimated for 2004 and 2010 using DMRB. The results showed that the annual
        mean objective for PM10 would be met in 2004 at these busy junctions, but in 2010 the
        objectives are likely to be exceeded. This may be attributed to the fact that the Borough
        of Poole has one of the highest background concentrations of PM10 in the UK, the
        predicted background for 2010 is estimated to be 18.9 μg.m-3 as an average with a
        maximum of 21.9 μgm-3.        There has been no significant change in traffic flow hence
        these junctions are not reassessed. There are no new busy junctions with relevant
        exposure identified.


10.8     SCREENING ASSESSMENT OF INDUSTRIAL SOURCES

The Guidance LAQM TG(03)1 lists the following processes as significant potential sources of PM10:

Part A (percentage of total emissions from all UK plant in this sector to the UK total in brackets)
Iron and steel (61)
Petroleum processes (4)
Combustion processes (13)
Cement/lime manufacture (7)
Carbonisation (2)
Gasification (4)
Non-ferrous metals (4)
Fertilizer production

Part B
Combustion plant 20-50 mwth
Furnaces 20-50 mwth
Coal and coke processes
Quarry Process
Roadstone coating
Rubber processes
China and clay processes
Coating powder
Coil coating

None of the Part A industrial processes in The Borough of Poole (Appendix B) operate these
processes or have the potential to emit significant quantities of PM 10. There has been no change to
this position.

There is one Part B industrial process (Tarmac Southern) identified in the 2003 USA to have the
potential to emit quantities of PM10. This process has been reviewed by the Borough and concluded
that any emissions were not significant. There are no new Part B industrial processes within the
Borough with the potential to emit significant quantities of PM10.




                                                                                             netcen   46
                                                                       AEAT/ENV/R/2209/Issue 1


10.9 SCREENING ASSESSMENT OF FUGITIVE AND UNCONTROLLED
SOURCES

10.9.1 Quarries and landfill sites
There are no recorded quarries in The Borough of Poole and there has been no change to this
position. There is one new registered landfill site (WH Whites Ltd) located on Arrowsmith Road.
Public exposure is possible within 1000 metres of source, however, there have been no complaints
of dust emissions from this site. Hence, a Detailed Assessment for PM 10 is not required at this
location.

10.9.2   Domestic solid fuel burning

There are no direct data for domestic coal burning available. In the 2003 USA report, the density
of coal burning households were estimated based on population, average household area and an
assumption of 5% of household using coal as primary source of fuel. The results indicated that the
PM10 objectives for 2004 are unlikely to be exceeded caused by domestic solid fuel burning, but the
objectives to be met in 2010 may be exceeded. However, fuel use statistics in the NAEI database
for 2000 (as discussed previously in section 9.8.1) indicated that the proportion of coal use in Poole
accounted for only 2%.

There is no significant domestic solid fuel burning identified in this assessment hence it is
considered that domestic solid fuel burning is unlikely put the air quality objective for PM 10 at risk
of exceedence.


10.10 SCREENING ASSESSMENT OF OTHER TRANSPORT SOURCES

10.10.1 Airports
There are no airports in The Borough of Poole or neighbouring authorities that have a throughput
of 5 million passengers per year and/or 500,000 tonnes of freight. There has been no change to
this position.


10.11 CONCLUSIONS FOR PM10 CONCENTRATIONS THE BOROUGH OF
POOLE

As discussed in the 2003 USA report, The Borough of Poole has a high background concentration of
PM10. Based on findings from other work8,9, it can be considered that due to the location of the
area a minimum contribution of sea-salt could be between 1 and 2 μg.m-3 of the annual mean
concentration and during some periods as much as 35% of the annual mean.

Monitoring data for PM10 in 2005 were obtained from neighbouring Local Authority (Bournemouth)
and the results indicated that the 2004 objectives were being met.

The DMRB screening model indicates that the 2004 objectives are unlikely to be exceeded for the
current year (2006) near A roads or busy junctions within the Borough. Although the results also
indicate that meeting the PM10 objectives for 2010 are likely to be a challenge, the 2010 objectives
are not currently included in Regulations hence a detailed assessment is not required for PM10.

However, it is recommended that The Borough of Poole consider setting up PM 10 monitoring points
at both background and roadside sites to assess the levels of PM 10 concentration within The
Borough.

11       Conclusions


11.1     CARBON MONOXIDE

Carbon dioxide is not monitored in The Borough of Poole. Monitoring data from Bournemouth and
Portsmouth indicate the maximum running 8-hour concentration in 2005 was 2.8 mgm-3, which is
significantly less than the objective value of 10 mgm -3. There are no roads in The Borough of Poole
that can be classified as „very busy‟ according to the criteria in the guidance.

A detailed assessment is not required for carbon monoxide in The Borough of Poole.

11.2     BENZENE

There are no roads in The Borough of Poole that can be classified as „very busy‟ according to the
criteria in the guidance. There are also no petrol stations that meet the criteria for assessment.
There is one Bulk Fuel Storage Facility operated by Texaco in Poole and the estimated benzene
emissions for 2005 indicate that the level would meet the 2003 and 2010 objectives for benzene.

A detailed assessment is not required for benzene in The Borough of Poole.

11.3     1,3-BUTADIENE

Estimated background concentrations and data from national monitoring stations indicate that the
2003 objective for 1,3-butadiene is likely to be achieved for the current year (2006). There are no
industrial processes, current or proposed, in The Borough of Poole, which have the potential to
emit 1,3-butadiene.

A detailed assessment is not required for 1,3-butadiene in The Borough of Poole.

11.4     LEAD

Emissions of lead from industrial processes in The Borough of Poole are not likely to exceed the
objectives for lead to be achieved in 2004 and 2008.

A detailed assessment is not required for lead in The Borough of Poole.

11.5     NITROGEN DIOXIDE

The monitoring results for 2005 show that six sites within The Borough of Poole exceeded the
annual mean objective of 40 μgm-3 for NO2. These locations are in Longfleet Road, Poole Road,
Ashley Road, Commercial Road, Mountbatten Roundabout and Pottery Junction.

Four of the exceeding locations namely Poole road, Commercial Road, Mountbatten Roundabout
and Ashley Road were subjected to detailed assessment in June 2005. The results of the detailed
assessment have shown that Poole Road and Commercial Road would meet the objective limit of
40 μgm-3. The reason for high concentration measured at Poole Road and Commercial Road are
due to its kerbside location. The Borough of Poole has decided to relocate the Poole Road diffusion
tube to the other side of the road where it is not positioned near the pedestrian crossing or building
which would restrict the flow of air around the diffusion tube. There is no current plan for the
relocation of the diffusion tube at Commercial Road.

Further investigation was pursued at Ashley Road and Mountbatten Roundabout to confirm whether
there is a requirement for the declaration of AQMAs. Three-month continuous monitoring results at
Ashley Road indicated that the level was below the annual mean objective for NO 2. In addition, an
updated dispersion modelling assessment16 was made at this location and the continuous
monitoring data was used to verify the model. The results showed that whilst it is likely that




                                                                                             netcen   49
                                                                     AEAT/ENV/R/2209/Issue 1


annual average NO2 concentrations are close to exceedence along the southern side of Ashley Road
in 2005, there are no areas of exceedence at locations where the objective would apply.

Diffusion tube monitoring at Mountbatten Roundabout was relocated to Dolberry Road South where
relevant exposure exists. The results collected to date have shown that the average NO2
concentration is well below the objective mean for NO 2 at this location. Based on these findings,
there is currently no need for the Borough of Poole to declare an AQMA at either Ashley Road or
areas in the vicinity of the Mountbatten Roundabout.       However, it is recommended that The
Borough of Poole keep both of these locations under review and report findings in the next
Progress Report.

Longfleet Road and Pottery Junction are new locations where a risk of exceedence of the annual
mean objective for NO2 is identified. These two locations are assessed in term of the relevant
exposure and the results show that both locations will meet the objectives at the nearest building
façade for 2006 and 2010.

A detailed assessment is not required for nitrogen dioxide.

11.6     SULPHUR DIOXIDE

There are no passenger diesel trains stopping at Poole, but there is one freight service runs to
Oasis Plant on Dawkins Road. It is observed that this diesel freight train is regularly stationary
with its engine running for 15 minutes or more at the Hamworthy Station on its return journey,
and there is relevant exposure within 15 metres of the train. However, as it is only observed to
happen at most on one occasion per day a detailed assessment is not therefore required at this
stage. It is recommended that The Borough of Poole carry out a survey at Hamworthy to confirm
the typical duration and frequency of this freight train being stationary with its engine running at
the station.

There are no significant industrial or domestic sources of sulphur dioxide in The Borough of Poole.

A detailed assessment is not required for sulphur dioxide.

11.7     PM10

As discussed in the 2003 USA report, The Borough of Poole has a high background concentration of
PM10. Based on findings from other work8,9, it can be considered that due to the location of the
area a minimum contribution of sea-salt could be between 1 and 2 μg.m-3 of the annual mean
concentration and during some periods as much as 35% of the annual mean.

Monitoring data for PM10 in 2005 were obtained from neighbouring Local Authority (Bournemouth)
and the results indicated that the 2004 objectives were being met.

The DMRB screening model indicates that the 2004 objectives are unlikely to be exceeded for
current year (2006) near A roads or busy junctions within the Borough. Although the results also
indicate that meeting the PM10 objectives for 2010 are likely to be a challenge, the 2010 objectives
are not currently included in Regulations hence a detailed assessment is not required for PM10.

However, it is recommended that The Borough of Poole consider setting up PM10 monitoring points
at both background and road site to assess the levels of PM10 concentration within The Borough.

11.8     SUMMARY AND RECOMMENDATIONS

A detailed assessment is not required for carbon monoxide, benzene, 1,3-butadiene, lead, nitrogen
dioxide, PM10 and sulphur dioxide.

Two locations within the Borough (Ashley Road and Mountbatten Roundabout) were the subject of
consideration of declaring an AQMA for NO2 and further investigation was pursued to confirm the
decision.   Three-month continuous monitoring results at Ashley Road indicated that NO2
concentrations were below the annual mean objective for NO 2. Diffusion tube monitoring at
Mountbatten Roundabout was relocated to Dolberry South Road where relevant exposure occurs




                                                                                            netcen    50
                                                                    AEAT/ENV/R/2209/Issue 1


and the results so far indicated the level was also below the 2005 objective. It is recommended
that a longer period of observations should be made at these locations and to report results in the
next progress report. Based on the current findings, the likelihood of exceedence of the annual
mean objective of NO2 for 2005 could range from unlikely to possible. The Borough of Poole is
recommended to undertake a longer period of automatic monitoring at the relevant receptor on
Ashley Road to demonstrate compliance of the objective limits for NO2.

It is recommended that The Borough of Poole consider setting up PM10 monitoring points at both
background and roadside sites to assess the likely levels of PM10 concentrations within the
Borough.

Design Manual for Roads and Bridges (DMRB) - This screening method was
formulated by the former Department of Transport. The method gives a preliminary
indication of air quality near roads. The DMRB method requires information on vehicle
flow, HDV mix, vehicle speed and receptor-road distances. It contains a useful
database of vehicular emission factors for future years.

The method adopts the annual mean concentration as the base statistic. Background
pollutant levels are included explicitly in the calculations by adding an amount to the
annual mean traffic contribution using the Air Quality Archive (paragraph 6.09) or
default values The model also estimates, from the annual mean PM 10 prediction, the
number of days where the PM10 concentration exceeds the 50μg m-3 daily mean
objective. The latest version of the DMRB nomogram (1.02, dated February 2003) has
been used for this assessment. Details of the road layout cannot be specified.

     with residential properties
     close to the kerb

D)   Junctions.                      This was examined in the 2003 USA and DMRB indicated no exceedence. There has been no
                                     significant change in the traffic flow since the last USA hence these junctions are not
                                     reassessed. There are no new busy junctions where relevant exposure occurs identified.

E)   Busy streets where people       None
     may spend 1-hour or more
     close to traffic

F)   Roads with high flow of         None

C)    New industrial sources.        None present

D)    Industrial sources with        None present
      substantially increased
      emissions, or new relevant
      exposure

E)    Areas of domestic coal         None identified
      burning

F)    Small Boilers > 5 MW           All listed as being less than 0.4 MW.
      (thermal).

G)    Shipping                       There is less than 5000 shipping movements hence shipping is not considered a significant
                                     source of sulphur dioxide.

H)    Railway Locomotives            One diesel freight train is identified to be regularly stationary with its engine running for 15
                                     minutes or more at the Hamworthy Station on its return journey, and there is relevant
                                     exposure within 15 metres of the train. However, as it is only observed to happen at most
                                     on one occasion per day thus a detailed assessment is not required at this stage.

     AQMA                            the objective for 2004 was met

B) Monitoring data within an         No AQMAs declared for PM10
     AQMA

C) Busy roads and junctions in       Not in Scotland
     Scotland

D) Junctions.                        This was examined in the 2003 USA and DMRB indicated no exceedence. There has been no
                                     change to this position and there are no new busy junctions where relevant exposure occurs
                                     identified.

E)   Roads with high flow of buses   None
     and/or HGVs.

J)   Industrial sources with       None present
     substantially increased
     emissions, or new relevant
     exposure

K) Areas of domestic solid fuel    None identified
     burning

L)   Quarries / landfill sites /   There is one new registered landfill site (WH Whites Ltd) located on Arrowsmith Road. Public
     opencast coal / handling of   exposure is possible within 1000 metres of source, however, there have been no complaints
     dusty cargoes at ports etc.   of dust emissions from this site. Hence, a Detailed Assessment for PM 10 is not required at
                                   this location.

M) Aircraft                        None present
