Executive Summary
This report forms part of the statutory duty placed on local government to report progress in Local
Air Quality Management, under Part IV of the Environment Act 1995 and the Air Quality (England)
Regulations 2000 and subsequent Air Quality (England) (Amendment) Regulations 2002. It
provides an update on monitoring data within Bromsgrove District Council, an assessment of any
new developments which might have an impact on air quality and provides some context in relation
to wider policies and processes being used to improve air quality generally.
The monitoring carried out in the district has not identified any exceedences of the PM10 objectives.
For nitrogen dioxide, there are still widespread exceedences of the annual mean objective, though
no exceedences of the hourly objective have been identified. In the majority of cases, the
exceedences are within currently declared AQMAs. The exception is the area surrounding the
Worcester Road automatic monitor.
At the automatic monitoring location and at three diffusion tube monitoring locations along
Worcester Road, the annual mean nitrogen dioxide objective is being exceeded; these locations
are not currently within a declared AQMA. These sites are currently being investigated in a
Detailed Assessment.
There is one new residential development within Bromsgrove District Council on Worcester Road
which will require further investigation as part of the Detailed Assessment.
Concentrations do need to be closely monitored at diffusion tube site KR in future years to ensure
that there is no need to amend the existing Hagley Air Quality Management Area order, should the
1 hour objective be breached at a nearby location of relevant exposure.

Progress Report 2010 Bromsgrove District Council
J946 2 of 29 May 2010
1 Introduction
Description of Local Authority Area
1.1 Bromsgrove is a district within the county of Worcestershire with a population of 87,486
(Worcestershire County Council, 2001). The main urban areas in the district are the towns of
Bromsgrove, Hagley, Rubery and Wythall. The remaining part of the district is largely rural in
character. Bromsgrove is the hub of a series of roads, the primary ones being the M42, M5, A38,
A456, A435 A441 and A491. The main source of air pollution in the district is road traffic emissions
from these roads.
1.2 Bromsgrove District Council has declared three Air Quality Management Areas (AQMAs). The first
is located at Junction 1 of the M42 at Lickey End in Bromsgrove, the second is located at
Kidderminster Road, Hagley and the third is located at Redditch Road, Stoke Heath. Each of
these AQMAs have been declared as a result of measured or predicted exceedences of the annual
mean objective for nitrogen dioxide due to road traffic emissions. Other pollution sources, including
commercial, industrial and domestic sources, also make a contribution to background pollution
concentrations.
Purpose of Progress Report
1.3 Progress Reports are required in the intervening years between the three-yearly Updating and
Screening Assessment reports. Their purpose is to maintain continuity in the Local Air Quality
Management process.
1.4 They are not intended to be as detailed as Updating and Screening Assessment Reports, or to
require as much effort. However, if the Progress Report identifies the risk of exceedence of an Air
Quality Objective, the Local Authority (LA) should undertake a Detailed Assessment immediately,
and not wait until the next round of Review and Assessment.
Air Quality Objectives
1.5 The air quality objectives applicable to Local Air Quality Management (LAQM) in England are set
out in the Air Quality (England) Regulations 2000 (SI 928), and the Air Quality (England)
(Amendment) Regulations 2002 (SI 3043). They are shown in Table 1.1. This table shows the
objectives in units of microgrammes per cubic metre µg/m3 (for carbon monoxide the units used
are milligrammes per cubic metre, mg/m3). Table 1.1 includes the number of permitted
exceedences in any given year (where applicable).

Summary of Previous Review and Assessments
1.6 Bromsgrove District Council undertook the first round of review and assessment of air quality
between 1998 and 2002. The first round assessments resulted in the declaration an Air Quality
Management Area (AQMA) as a result of predicted exceedences of the annual mean objective for
nitrogen dioxide at Lickey End, due to road traffic emissions from the M42 (Junction 1).
1.7 The second round of review and assessment commenced with the 2003 Updating and Screening
Assessment (USA). This report concluded that a Detailed Assessment would be required for
nitrogen dioxide due to road traffic emissions from the A38 Redditch Road (Aston Road Industrial
Estate), the A456/A491 Hagley, and the A38 Marlbrook Crossroads. The Detailed Assessment
concluded that the declaration of further AQMAs was not required.
1.8 The third round of review and assessment commenced with the 2006 USA. This report concluded
that a Detailed Assessment was required for nitrogen dioxide due to measured exceedences of the
annual mean objective at the nearest receptors to two diffusion tube monitoring locations on
Redditch Road, Buntsford Hill and Kidderminster Road, Hagley. Triplicate diffusion tube monitoring
was introduced in these locations. The Detailed Assessment 2007 concluded that the annual
mean objective for nitrogen dioxide was likely to be exceeded at Redditch Road, Buntsford Hill. As
a consequence Bromsgrove District Council installed a continuous monitor at Redditch Road,
Buntsford Hill in March 2008 for a six-month period. The results of this monitoring were considered
within the Detailed Assessment 2009 which covered Kidderminster Road, Hagley, as well as a
number of areas in Bromsgrove town centre, where measured exceedences were identified in the
2008 Progress Report. As a result of the report findings a continuous monitoring site was installed
at Worcester Road and a detailed traffic survey within Bromsgrove town centre was undertaken.
1.9 As a result of the 2009 Detailed Assessment two Air Quality Management Areas (AQMAs) were
declared for Kidderminster Road, Hagley and Redditch Road, Stoke Heath, effective as of the 17th
of February 2010 for exceedences of the nitrogen dioxide annual mean objective. To date,
therefore, three AQMA’s have been declared within Bromsgrove, all in relation to the nitrogen
dioxide annual mean objective.

2 New Monitoring Data
Summary of Monitoring Undertaken
Automatic Monitoring Sites
2.1 Bromsgrove District Council operates an automatic monitoring site at Lickey End, Bromsgrove
measuring nitrogen dioxide alongside the M42 Junction 1 (Figure 2.1). An additional monitoring
site was located at Worcester Road from April 2009 to April 2010, monitoring both nitrogen dioxide
and particulate matter (PM10) (Figure 2.2).

Non-Automatic Monitoring
2.2 Bromsgrove District Council also monitors annual mean nitrogen dioxide concentrations using
passive diffusion tubes located across its administrative area. The locations of the diffusion tubes
are described in Table 2.2 and shown in Figures 2.3 to 2.7.
2.3 Bromsgrove District Council has deployed diffusion tubes prepared and analysed by Gradko, (20%
TEA in water). For further information see Appendix A. Diffusion tubes are co-located, in triplicate,
with the roadside continuous monitor at Worcester Road and the AURN monitor at Lickey End, to
establish the bias of the diffusion tubes compared to the continuous monitoring data. Appendix A
provides details of the bias correction factors used within this report. The 2009 results from the
WASP scheme show Gradko diffusion tubes had good performance, whilst laboratory precision
was good.

Automatic Monitoring Data
2.4 The nitrogen dioxide concentrations measured by the automatic monitor in 2009 show that the
annual mean objective has been exceeded at both Lickey End and Worcester Road (Table 2.3a).
However the hourly mean objective has been met at both monitoring sites (Table 2.3b).

2.5 Automatic monitoring of nitrogen dioxide concentrations at the Lickey End monitoring station has
demonstrated that annual mean concentrations of nitrogen dioxide have remained fairly static over
the last seven years, but consistently above the annual mean objective (shown in red) (Figure 2.8).
On the other hand, the number of hours above the hourly mean objective has been very variable
over the last four years, with one year showing an exceedence (Figure 2.9).

Diffusion Tube Monitoring Data
2.6 The nitrogen dioxide results measured by diffusion tubes in 2009 show that the annual mean
objective has been exceeded at eight locations five of which are within existing AQMA’s (Table
2.4). Sites showing exceedences outside of currently declared AQMAs are as follows:
• BC/a/b Ye Olde Black Cross, Worcester Road
• DL Denise Lesley, Worcester Road
• BCX 16 Worcester Road
These locations are currently being investigated in a Detailed Assessment.

a As a result of low data capture. Results have been annualised following guidance in Box 3.2 of TG(09) See Appendix A for further details.
b An error in diffusion tube labelling in previous years has resulted in there being two tubes labelled ‘10’, 77a Park Road is the only tube labelled ‘10’ as of 2009.
2.7 Monitoring at location KR indicates that there may be an exceedence of the hourly mean nitrogen
dioxide objective at this location, as annual mean concentrations above 60 μg/m3 have been
measured. This monitoring location is roadside, however, and if the distance from road calculator
(Defra, 2010) is used the concentration at the property is only predicted to be 46 μg/m3. As there
is no exposure at KR over the 1 hour averaging time of the objective it will not be necessary to
amend the Hagley AQMA order, however, concentrations at this monitoring locations will need to
be closely monitored in future years.
2.8 The results of diffusion tube monitoring of nitrogen dioxide concentrations across Bromsgrove are
presented in figures 2.9, 2.10 and 2.11. At the majority of monitoring locations there is no distinct
trend discernable within the data over a 4 year period. Furthermore concentrations are below the
annual mean objective at most locations though at six locations concentrations have exceeded the
objective in every year across the period 2006 – 2009.

PM10
2.9 PM10 concentrations were measured at the Worcester Road continuous monitoring site from April
2009 to April 2010. As only one year of monitoring data has been collected it is not possible to
consider the trend in concentrations. Concentrations measured over this period demonstrated no
exceedence of either the annual or 24 hour mean PM10 objective.

Summary of Compliance with AQS Objectives
Bromsgrove District Council has measured concentrations of nitrogen dioxide above the annual mean objective at relevant locations outside of the AQMAs, within Worcester Road. This area has previously been identified and a Detailed Assessment is already underway. No further areas require Detailed Assessment.
3 New Local Developments
3.1 Since the 2009 Updating and Screening Assessment was produced no new developments, which
may have an impact on air quality have been identified, this may be linked to the economic
downturn. A small residential development is currently being constructed on Worcester Road
however; which may however, be affected by existing poor air quality. It is contained within the
Detailed Assessment study area and will be considered as part of this Assessment.
Bromsgrove District Council confirms that there are no new or newly identified local developments which may have an impact on air quality within the Local Authority area.
Progress Report 2010 Bromsgrove District Council

4 Regional Air Quality Strategy
4.1 Herefordshire Council and the authorities under Worcestershire Council have developed an Air
Quality Strategy (AQS) (Herefordshire and Worcestershire, 2009a). This AQS was developed to
provide support for achieving the national air quality objectives and also to raise the profile of air
quality issues with relevant bodies. Reducing concentrations of nitrogen dioxide within any area
designated an AQMA to below 40 μg/m3 by 2010/2011 is a key target contained with the strategy.
This target is also contained within the Herefordshire and Worcestershire Local Transport Plans.
National Indicator 194 incorporates target reductions for emissions of both NOx and PM10 from
local authority’s estates and operations, these targets are also incorporated within the strategy.
5 Planning Applications
5.1 A planning application for a Sainsbury’s Superstore and additional retail developments on
Birmingham Road has been received by Bromsgrove DC. If approved, this development will cover
around 1,076 square metres and will include 479 parking spaces; consequently it will have the
potential to have significant air quality impacts. The development will need to be considered in the
2012 USA if the application is approved.

6 Air Quality Planning Policies
6.1 The Bromsgrove Local Plan was adopted in 2004; however recent changes to the planning
legislation require the Council to replace the Local Plan with a Local Development Framework
(LDF). This portfolio of planning documents, individually known as Local Development Documents,
will deliver the spatial development strategy for Bromsgrove and build upon existing local and
regional strategies and initiatives. Core policies within the Local Plan are to remain in operation
until they are replaced by policies in the new development plan documents (Bromsgrove District
Council, 2004). Bromsgrove District Council’s Core Strategy is the most important document in the
LDF; the Draft Core Strategy went out for consultation in 2009.
6.2 The LDF vision states that: ‘Air quality will have been improved and the carbon footprint of the
District will have significantly reduced, with a sustainable increase of on site renewable energy
being incorporated into new developments.’
6.3 ES14 of the Local Plan states that: ‘Where development is proposed close to sources of pollution
and this would be likely to adversely affect the amenity of those occupying the subsequent
scheme; or where a proposal for a new development may itself be a potential source of pollution,
the District Council will seek to ensure that the conflict between such land uses can be ameliorated
to its satisfaction…”
6.4 At a regional planning level, Herefordshire and Worcestershire are encompassed within the
Regional Spatial Strategy (RSS) for the West Midlands (GOWM, 2009). Within the Regional
Spatial Strategy, the policy most relevant to air quality is policy QE4 C, which states that “Local
authorities and others should also encourage patterns of development which maintain and improve
air quality and minimise the impact of noise upon public space”. The importance of the air quality
management process is recognised in paragraph 8.45 of the RSS.
6.5 The Hereford and Worcester Air Quality Planning Protocol outlines air quality policy within Hereford
and Worcester and details requirements for air quality assessments (Herefordshire and
Worcestershire County Councils, 2009b). The protocol advises that air quality assessments
should be carried out for developments which may introduce new exposure to existing sources of
air pollutants.

J946 23 of 29 May 2010
7 Local Transport Plans and Strategies
7.1 Bromsgrove District Council is encompassed by The Worcestershire Local Transport Plan 2
(LTP2).
7.2 LTP2 identifies accessibility, congestion, economic regeneration and the environment, particularly
air quality, as being the main transport issues relating to Bromsgrove (Worcestershire County
Council, 2006).
8 Climate Change Strategies
8.1 Bromsgrove District Council is signed up to both the Worcestershire Climate Change Pledge
(Worcestershire County Council, 2009) and the Nottingham Declaration on Climate Change
(Energy Saving Trust, 2000) they are also a partner within the Worcestershire Partnership Climate
Change Strategy (Worcestershire County Council, 2008).
8.2 Those who have signed up to the Worcestershire Climate Change Pledge have committed to raise
awareness of Climate Change issues among staff and in activities and to monitor and reduce
energy use.
8.3 The Nottingham Declaration on Climate Change requires each council that signs up to contribute
at a local level to the delivery of the UK Climate Change Programme and to prepare a plan with
local communities to address the causes and effects of Climate Change.

9 Conclusions and Proposed Actions
Conclusions from New Monitoring Data
9.1 Exceedences of the annual mean air quality objective have been identified outside of Bromsgrove
District Council’s three existing air quality management areas. The Worcester Road continuous
monitor and a number of diffusion tubes in the vicinity recorded annual mean nitrogen dioxide
concentrations greater than 40 μg/m3. A Detailed Assessment is already underway for this area.
9.2 Automatic monitoring of nitrogen dioxide concentrations at the Lickey End monitoring station has
demonstrated that annual mean concentrations of nitrogen dioxide have remained fairly static over
the last seven years, remaining consistently above the annual mean objective level. In 2009 no
exceedences of the one hour objective were observed at this site.
9.3 At one of the diffusion tube monitoring locations (KR) a concentration of 63 μg/m3 has been
monitored, which if this site were considered to be representative of relevant exposure would
indicate a breach of the nitrogen dioxide hourly mean objective, however there is no relevant
exposure over the averaging period of the objective at this location, and concentrations at the
nearest residential façade are predicted to be 46 μg/m3. As this location is currently contained
within the Hagley annual mean objective AQMA it will not be necessary to amend the order, but
this will need to be closely monitored in future years.
9.4 One year of automatic monitoring of particulate matter has been carried out at the Worcester Road
monitoring site. This monitoring has demonstrated that there are no PM10 objective exceedences
at this monitoring site.
Conclusions relating to New Local Developments
9.5 Bromsgrove District Council has confirmed that there are no new developments that would trigger
the requirement for a Detailed Assessment. However the proposed Sainsbury’s Superstore and
additional retail developments on Birmingham Road will require further investigation within the
2012 USA, should planning permission be granted.
9.6 The one residential development currently under construction at 186 – 190 Worcester Road will be
considered as part of the Detailed Assessment that is currently underway.
Proposed Actions
9.7 A Detailed Assessment for nitrogen dioxide in the vicinity of Worcester Road is already underway.
Close monitoring of nitrogen dioxide concentrations at KR in future years will be required to ensure
there is no breach of the hourly mean objective.

11 Appendix A: QA:QC of Data
Diffusion Tube Bias Adjustment Factors
11.1 Gradko 20% TEA in water diffusion tubes have been deployed across the district. The factor
available from the national bias adjustment factor spreadsheet (v.03/10) was generated by 33
studies and is 0.90 for 2009.
Factor from Local Co-location Studies
11.2 Diffusion tubes have been co-located, in triplicate, with the continuous monitors at Lickey End and
Worcester Road, as the Worcester Road monitoring was not carried out to across a calendar year
only the data from Lickey End have been used to establish the bias of the diffusion tubes
compared to the continuous monitoring data.

Discussion of Choice of Factor to Use
11.3 Both a local and a national Bias Adjustment Factor are available. Results presented in this report
have had the local Bias Adjustment Factor applied, as use of the local factor represents a
worst-case scenario and is therefore precautionary.
PM Monitoring Adjustment
11.4 The PM10 monitor at Worcester Road is a Beta Attenuation Mass monitor (BAM). The BAM inlet is
unheated and therefore technical guidance has been followed in that the annual mean has been
divided by 1.21 to provide gravimetric equivalent concentrations (Defra, 2009).
Short-term to Long-term Data adjustment
11.5 Data from three background Automatic Urban and Rural Network (AURN) monitoring sites were
used to adjust short-term monitoring data; these were West Bromwich, Leamington Spa and
Coventry. The first period mean shown below in Table A2, is for June to December, relating to
diffusion tube 8 (9 Market Way). Other period means were calculated to adjust the following tubes

QA/QC of automatic monitoring
11.6 Bromsgrove District Council calibrates the stations on a fortnightly basis and Air Quality
Consultants Ltd ratify the data. The equipment supplier Enviro Technology services the station on
a six monthly routine basis and AEA undertakes 6-monthly audits of the station. QA/QC
procedures for the site are equivalent to the UK AURN procedures.

QA/QC of diffusion tube monitoring
11.7 In the WASP scheme, analysis of nitrogen dioxide diffusion tubes, October 2008 – October 2009
shows Gradko tubes had good performance1. In a separate study, the QA/QC results for precision
of Gradko tubes were good2. The precision of the Lickey End diffusion tubes was good overall.
Nitrogen dioxide with distance from Road Calculator Input
11.8 Diffusion tube location KR monitored a concentration of 63 μg/m3 of nitrogen dioxide. The
concentration at the façade of the nearest residential property was calculated using the input
values shown in the following table.

This calculator allows you to predict the annual mean NO2 concentration for a location ("receptor") that is close to a monitoring site, but nearer or further the kerb than the monitor. The next sheet shows your results on a graph.
Enter data into the yellow cells
Step 1 How far from the KERB was your measurement made (in metres)? (Note 1) 0 1.7 metres
Step 2 How far from the KERB is your receptor (in metres)? (Note 1) 0 8.1 metres
Step 4 What is the local annual mean background NO2 concentration (in µg/m3)? (Note 2) 0 14.8 µg/m3
Step 3 What is your measured annual mean NO2 concentration (in µg/m3)? (Note 2) 0 63 µg/m3
Result The predicted annual mean NO2 concentration (in µg/m3) at your receptor (Note 3) 46.0 µg/m3
Note 1: This should be measured horizontally from the kerb and assumes that the monitor and receptor have similar elevations. Each distance should be greater than 0.1m and less than 50m (In practice, using a value of 0.1m when the monitor is closer to the kerb than this is likely to be reasonable). The receptor is the location for which you wish to make your prediction. The monitor can either be closer to the kerb than the receptor, or further from the kerb than the receptor. The closer the monitor and the receptor are to each other, the more reliable the prediction will be. When your receptor is further from the kerb than your monitor, it is recommended that the receptor and monitor should be within 20m of each other. When your receptor is closer to the kerb than your monitor, it is recommended that the receptor and monitor should be within 10m of each other.
Note 2: The measurement and the background must be for the same year. The background concentration could come from the national maps published at www.airquality.co.uk, or alternatively from a nearby monitor in a background location.
Note 3: The calculator follows the procedure set out in Box 2.2 of LAQM TG(08). The results will have a greater uncertainty than the measured data. More confidence can be placed in results where the distance between the monitor and the receptor is small than where it is large.
