September 2009 ii Updating and Screening Assessment Daventry District Council

Executive Summary

Part IV of the Environment Act 1995 places a statutory duty on local authorities to review and assess the air quality within their area and take account of Government guidance when undertaking such work. This Updating and Screening Assessment (USA) is a requirement of the third round of review and assessment for local authorities.

The Report has been undertaken in accordance with the recently released LAQM.TG(09) technical guidance note and the web based USA template on the Review and Assessment Report Submission Website.

This Updating and Screening Assessment has concluded that Daventry District Council is not required to carry out a Detailed Review and Assessment for carbon monoxide, benzene, 1,3- butadiene, lead, nitrogen dioxide, PM10 or sulphur dioxide.

The recent Progress Report 2008/09 was completed in May 2009. The data for NO2 monitoring results in the vicinity of the M1 (the data included results to the end of 2008) concluded that there was no exceedance of the annual average at points representative of relevant exposure. Therefore no detailed assessments were recommended in the report.

As a collective the monitoring data for NO2 across the district from the years preceeding 2005 has been plotted and it is evident from the graph below that a small decreasing trend in levels is taking place. This makes a favourable comparison with the projected NO2 values for 2010 using the “year adjustment calculator” tool at http://www.airquality.co.uk/laqm/tools/Year_Adjustment_Calculator.xls

It is only the kerbside monitoring sites to the M1, which do not have any appropriate receptors that exceed the annual average. It is therefore not necessary to proceed to a detailed assessment for NO2 in Daventry district, however diffusion tube monitoring at the M1 locations will continue and close scrutiny paid to this data.

1.1 Description of Local Authority Area

Daventry District is a predominantly rural district with the larger and most northerly section occupying that part of the Northamptonshire Uplands lying to the east of the Gap section of the . This northern part of the district stretches from in the south to and the border in the north; from the town of Rugby in the west almost to Kettering and the A6 Towns in the east. A smaller part of the District is situated to the south west of the M1 Motorway, with its southernmost boundary coming to within 6 miles of the Oxfordshire border at .

Map 1.0 - Daventry District

The population of the District was estimated in mid 1995 to number some 64,800 people. The administrative centre of the district is Daventry town itself, which is located within this southern area, some 8 miles from Junction 16 of the M1. The town has grown steadily since the early sixties, having been the subject of an expansion scheme designed to cater for Birmingham people needing alternative housing accommodation.

The population of Daventry Town at mid 1996 was approximately 19,100 and the town is continuing to grow as an employment, shopping and recreational centre for the surrounding rural area. Whilst the town has become well known as an ideal location for warehousing, not least as the home of Ford Motor Company's major distribution centre, it has gradually acquired a wide range of manufacturing and service industries, located on three industrial estates.

1.2 Purpose of Report

This report fulfils the requirements of the Local Air Quality Management process as set out in Part IV of the Environment Act (1995), the Air Quality Strategy for , Scotland, Wales and Northern Ireland 2007 and the relevant Policy and Technical

Guidance documents. The LAQM process places an obligation on all local authorities to regularly review and assess air quality in their areas, and to determine whether or not the air quality objectives are likely to be achieved. Where exceedences are considered likely, the local authority must then declare an Air Quality Management Area (AQMA) and prepare an Air Quality Action Plan (AQAP) setting out the measures it intends to put in place in pursuit of the objectives.

1.3 Air Quality Objectives

The air quality objectives applicable to LAQM in England are set out in the Air Quality (England) Regulations 2000 (SI 928), The Air Quality (England) (Amendment) Regulations 2002 (SI 3043), and are shown in Table 1.1. This table shows the objectives in units of microgrammes per cubic metre μg/m3 (milligrammes per cubic metre, mg/m3 for carbon monoxide) with the number of exceedences in each year that are permitted (where applicable).

1.4 Summary of Previous Review and Assessments

Between 1998 and 2000, Daventry District Council undertook its first round of review and assessments of air quality. The first round assessments concluded that pollutant concentrations were likely to meet the air quality objectives and it was not necessary for Daventry District Council to declare any AQMA’s. The updating and screening assessment from 2003 concluded that some properties close to the M1 may exceed the objectives, however the monitoring data at locations close to the M1 was not representative of relevant exposure. It was agreed after discussion between Daventry District Council and DEFRA that there was no need to proceed to a detailed assessment for NO2. The 2005 progress report also reported that monitored NO2 concentrations in the vicinity of the M1 were exceeding the objectives; however these locations were again not representative of relevant exposure as the monitoring tubes were located virtually next to the hard shoulder and not near any potential public exposure.

The 2006 Updating and Screening Assessment undertaken by Bureau Veritas concluded that the air quality objectives for benzene, 1,3-butadiene, carbon monoxide, lead, PM10 and sulphur dioxide will be met and there would be no requirement to undertake a detailed assessment of these pollutants. The predicted annual mean NO2 concentrations for a number of monitoring sites had indicated that the annual mean would be exceeded. However the road traffic contribution to the predicted pollutant concentrations reported was doubled to compensate for restricted dispersion of vehicle emissions in street canyons which was described in LAQM.TG(03) at the time. The circumstances for relevant exposure at the monitored locations is that the canyon effect contains the pollutants at the carriageway and actually minimises the effect upon those properties located at the top of a sizeable embankment as the M1 travels through a cutting. The is evident with the monitoring results at Lilbourne (tubes N12 and N13) detailed in table 1.2. The DMRB model is not able to take such topography conditions into consideration in its calculations. Bureau Veritas concluded that a detailed assessment is required based upon the predicted annual mean NO2 concentrations exceeding the objective in the vicinity of the M1 at Haythog Farm, Road and Greenhill Farm. However Bureau Veritas concluded that a cautious approach be taken of the NO2 results as the data is based upon predictions with a street canyon effect and the monitored concentrations exceeding the AQS objective close to the M1, were not in the immediate vicinity of relevant receptors. The DMRB predicted NO2 concentration for Greenhill Farm was under the annual mean objective however with the street canyon effect the level exceeded by a considerable amount. Greenhill Farm is located at the start of a cutting rather than in a canyon however investigations have confirmed that the farm is now disused.

Diffusion tubes require a bias factor to be determined to ensure the accuracy of the measurements. This is done by co-location of tubes with a continuous analyser or that tubes are in triplicate at the measurement location so to improve precision and accuracy in the results. However bias of diffusion tubes is largely associated with the laboratory and preparation method used. The bias correction factor for monthly exposure of Gradko tubes made up with 50% TEA in water is calculated each year available at the UWE helpdesk web site http://www.uwe.ac.uk/aqm/review/R&Asupport/diffusiontube050509.xls

2.2 Comparison of Monitoring Results with AQ Objectives

2.2.1 Benzene

There is a local monitoring scheme for monitoring Benzene using passive diffusion tubes; there have been no annual mean concentration exceedances above the 2010 objective of 5μg/m3 since the monitoring began in 2002 (see table 1.3 below). Data collection for the benzene diffusion tubes at each of the sites for each of the years s virtually 100%. On occasions an odd tube has gone missing for the 12 month period so the annual average is divided by 11 months rather than 12.

2.2.2 Nitrogen Dioxide

Diffusion Tube Monitoring Data

From the results table on page 14 it can be seen that the background level of NO2 monitored at Haythog Farm has dropped significantly since 2004 to below the 40μg/m3 maximum annual mean. This tube is located at the entrance to the farm. The tube located on the façade of the Farmhouse has consistently recorded an annual average of 35.7μg m3, 35.5μg m3 and 35.3 μg m3 since location in 2004. The location of this tube at the farmhouse was identified as best representing the most relevant public exposure at the location. Haythog Farm will continue to be closely monitored by Daventry District Council. The tubes at Moulton, Naseby and Horsepool (Lilbourne) show a slight downward trend (see graph 1.2 on page 14), in line with a favourable comparison to the projected NO2 values for 2010 using the “Year Adjustment Calculator tool” at the help desk web site:-

September 2009 12 Updating and Screening Assessment

Daventry District Council http://www.airquality.co.uk/laqm/tools/Year_Adjustment_Calculator.xls

Overall the annual mean at the majority of sites is well below the 40 μg m3 objective and a number of tubes show the small but reasonably consistent downward trend as predicted by the guidance as demonstrated in the graph below. Those sites which do exceed the annual mean objective are kerbside to the M1 motorway and do not have relevant public exposure.

2.2.3 PM10

There is currently no monitoring of PM10 within Daventry District. There were no reported exceedances of the 15-minute, hourly or daily AQS objectives at sites within the East , and therefore it is likely that there would be no measured exceedances of PM10 objectives in Daventry district.

2.2.4 Sulphur Dioxide

There is currently no continuous or indicative monitoring of sulphur dioxide within Daventry district. Sulphur dioxide concentrations measured during 2008 at all sites within the UK automatic monitoring network including busy roadside sites met the AQS objective for 2008. There were no reported exceedances of the 15-minute, hourly or daily AQS objectives at sites within the http://www.airquality.co.uk/data_and_statistics.php. Daventry district does not have any history of coal mining where solid fuel usage would have been likely to be used as a means of heating rather than natural gas.

2.2.5 Carbon Monoxide

There is currently no monitoring undertaken for carbon monoxide within Daventry District. The Updating and Screening Assessment report in 2006 concluded there are no significant industrial sources within the district or in neighbouring districts that are likely to have a significant impact on carbon monoxide levels within Daventry District. The major source of carbon monoxide is from road traffic. Monitoring data from across the UK indicates that the carbon monoxide objective is only likely to be exceeded next to very busy roads and junctions. Results from national monitoring data indicate ( source http://www.airquality.co.uk/data_and_statistics.php) that even in the worst-case scenario of a kerbside location, the air quality objective is being met. It is therefore concluded that the objective was met at all locations within the district by the end of 2008. There has been no change to the previously reported scenario.

2.2.6 1,3 -Butadiene

There is currently no monitoring of 1,3 –Butadiene carried out within Daventry District. Monitoring is carried out across the UK as part of the national Automatic Urban and Rural Monitoring Network (AURN). AQS objectives were met for 1,3 – Butadiene at all AURN monitoring sites in 2008 (source http://www.airquality.co.uk/data_and_statistics.php). There are no industrial sources in Daventry district where 1,3 – Butadiene is emitted. No further action is required with respect to 1,3 – Butadiene.

3 Road Traffic Sources

Transport statistics produced by Northamptonshire County Council and the Highways Agency indicate that on the M1, traffic flows exceed 100,000 AADT between the junction 17-18 and 18-19. The flows along the A classified roads in the district have been assessed and traffic data (ADT) obtained from Northamptonshire County Council for 2008 which has been compared with traffic data from previous years. This is detailed in Appendix 1 with the traffic monitoring locations shown in the respective map.

3.1 Narrow Congested Streets with Residential Properties Close to the Kerb

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

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

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

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

Daventry District Council confirms that there are no new/newly-identified roads with high flows of buses/HDVs.

3.4 Junctions

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

5 Industrial Sources 5.1 Industrial Installations

5.1.2 Regulated Industrial Processes The district has a small number of industrial processes (Part B), which are regulated under the Pollution Prevention and Control Act 1999, through the Local Authority Pollution Prevention & Control (LAPPC) regime. A list of the prescribed processes is detailed in appendix 1. There are no Part A2 or Environment Agency controlled Part A processes in the district. There have been no new applications for substantial regulated processes since the 2003 and 2006 USA report in the district. Petrol stations are a regulated process and the only parameter which the guidance requires attention is if a station is dispensing greater than 2 million litres per year, is near to a busy road (>30,00 AADT) and there is relevant exposure within 10 meters of the petrol pumps. The only road with traffic flows greater than 30,000 ADT in Daventry District is the M1 service stations at the Watford Gap services. However there is no relevant exposure within 10 meters of the pumps.

5.1.3 Non-Regulated Industrial Sources

There are a number of other industrial processes located in Daventry which because of their scale or process are not regulated under the Pollution Prevention and Control Act 1999. These processes tend to be associated with small industrial developments or warehousing/distribution. These processes by their nature or size do not have an impact upon ambient air quality levels. There have been no new landfill or quarrying/mineral operations in Daventry district and neither has there been the installation of any new boiler plant rated at above 5MW.

5.1.4 New or Proposed Installations for which an Air Quality Assessment has been Carried Out

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

5.1.5 Existing Installations where Emissions have Increased Substantially or New Relevant Exposure has been Introduced

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

6 Commercial and Domestic Sources

6.1 Biomass Combustion – Individual Installations

Daventry District Council confirms that there are no biomass combustion plant in the Local Authority area. Neither has there been any planning applications received for such plant.

6.2 Biomass Combustion – Combined Impacts

Daventry District Council confirms that there are no biomass combustion plant in the Local Authority area.

6.3 Domestic Solid-Fuel Burning

Daventry District Council is not an area where mining has taken place and where concessionary solid fuel would still be used. The majority of properties in Daventry utilise natural gas for heating. For the more rural areas there is a mixture of liquefied propane gas (LPG) and oil fired central heating systems. Again burning solid fuel from a legacy of mining activity is not present in the rural areas of Daventry district. Domestic solid fuel burning therefore does not have an effect upon air quality in Daventry district.

7 Fugitive or Uncontrolled Sources

Daventry District Council confirms that there are no sources of fugitive or uncontrolled sources within the district such as quarrying, mineral extraction or open cast operations. The district does not have specific mineral deposits which would actively be quarried. No planning applications have been made for such operations in the future.

8 Conclusions and Proposed Actions

8.1 Conclusions from New Monitoring Data

The Report has compared new monitoring data from 2006 onwards against the relevant Air Quality Objectives. The conclusions are that no further investigation is required for

Nitrogen Dioxide Carbon Monoxide Benzene 1,3-Butadiene Lead Sulphur Dioxide

Fine Particles – PM10

Further monitoring will be continued for Nitrogen Dioxide at key locations in the district. Haythog Farm will continue to be closely monitored by Daventry District Council as the most sensitive receptor in the district to the M1 motorway. Consideration for the location of additional NO2 tubes will be investigated with respect to the proposed growth agenda for the district over the next 10 to 15 years. This has already begun with two tubes previously located on the Watford Gap motorway services being redeployed to the villages of Weedon and Flore adjacent to the A45. These two sites will be intermediary and reflect relevant exposure to the villages from the road traffic source. The A45 takes traffic from junction 16 of the M1 and during peak hours congestion is experienced through the village of Weedon and sometimes Flore. The A45 will become a key route to serve the proposed growth of Daventry in the future. Further consideration to the air quality impacts of the proposed developments will be made once EIA have been received from developers. The slight

decrease in NO2 annual mean concentrations could be as a result of improved vehicle technology and tighter fuel standards over recent years, however the proposed growth of Daventry could present new challenges for maintaining air quality and implementing sustainable transport solutions.

8.2 Conclusions from Assessment of Sources

The report concludes that since the 2006 USA report there has been no change to the likely impacts from local developments, road transport, industrial installations, commercial/domestic sources, fugitive emissions, residential and commercial emissions. No major residential developments have taken place and neither has any commercial development/expansion occurred.

The Milton Keynes and South Midlands Sub-Regional Strategy published by the Department for Communities and Local Government covers the alterations to the Regional Spatial Strategies covering the East of England, East Midlands and South East of England. This provides an ongoing framework for the development of

September 2009 25 Updating and Screening Assessment

Daventry District Council

residential and employment land in which to meet development targets up until 2021. Daventry has been set specific development growth targets and is currently developing a Core Strategy as part of its new Local Development Framework for the district. This sets out the key issues raised by the Regional Spatial Strategy, including the development growth targets and possible options for its delivery. The Milton Keynes and South Midlands Sub-Regional Strategy specifically states that “ Daventry will grow towards a population of about 40,000 by 2021, seeking to consolidate and extend its role by revitalising and extending the role of the town centre as a Sub-Regional Centre offering improved shopping facilities and a wider range of jobs and services. Sustainable growth will take place both by means of intensification within present built-up area and expanding onto Greenfield sites through one or more sustainable urban extensions”

Three schemes have been proposed and involve the development of up to 10,000 new homes associated with Daventry. The developments proposed are the three sites of Danetree, Churchfields and Monksmoor. These are located to the east of Daventry. The schemes are currently at the pre application stage and no formal planning approval has been made. Full EIA shall be required from potential developers of which close scrutiny will be paid to ensuring sustainable developments and transport infrastructure at all aspects. In the recent economic climate development of such extensive schemes may be someway off.

8.3 Proposed Actions

The Updating and Screening Assessment has not identified the need for Daventry District Council to proceed to a detailed assessment for any of the pollutants prescribed in the regulations.

The extensive NO2 diffusion tube monitoring locations in the district generally remain the same however the two diffusion tubes located at the M1 Watford Gap services have been moved to monitor NO2 levels at the village of Flore and Weedon. The reason for beginning to monitor at this location is that the village of Weedon lies on a cross roads of the A5 trunk road and the A45. This junction is signal controlled, but can cause stationary queuing traffic at peak times. The majority of Weedon village is located well away from the roadside. At Flore sometimes the queuing traffic can reach into the village. It has been proposed that a bypass to ease congestion and cut journey times could be built as part of the regional spatial strategy for the town of Daventry so that there is improved links with the M1 motorway. The monitoring began in June 2009.

The diffusion tube monitoring for Benzene has recorded compliance at all locations over each result since monitoring began in 2002. It has been decided that this monitoring will cease from July 2009.

There has been no requirement to declare any AQMA’s in the district in the past and the results of this USA report for 2009 confirm that there is no evidence that Daventry District Council require to proceed to declare any AQMA’s now or in the proceeding future.

A progress report will be submitted in 2010.

Appendix 1: QA:QC Data

Diffusion Tube Bias Adjustment Factors

Diffusion tubes require a bias factor to be determined to ensure the accuracy of the measurements. This is done by co-location of tubes with a continuous analyser or that tubes are in triplicate at the measurement location so to improve precision and accuracy in the results. However bias of diffusion tubes is largely associated with the laboratory and preparation method used. The bias correction factor for monthly exposure of Gradko tubes made up with 50% TEA in water is calculated each year available at the UWE helpdesk web site http://www.uwe.ac.uk/aqm/review/R&Asupport/diffusiontube050509.xls

The bias adjustment factors used for the NO2 diffusion tube results are listed below

Year Bias adjustment factor 2006 0.96 2007 0.93 2008 1.05

QA/QC of diffusion tube monitoring

Gradco Ltd supplies and analyses the diffusion tubes using the 50% TEA (Triethanolamine) in water method. Gradco participates in the UK National Diffusion Tube Network and the Workplace Analysis Scheme for Efficiency WASP). They currently hold UKAS accreditation for analysis of diffusion tubes and consistently achieve the highest performance level in annual field inter-laboratory performance comparisons. The results for laboratory performance have been assessed from the helpdesk web site. http://www.uwe.ac.uk/aqm/review/R&Asupport/Tube_Precision_2008_(May_09).pdf
