LAQM Annual Status Report 2019 Corby Borough Council
Executive Summary: Air Quality in Our Area Air Quality in Corby
Air pollution is associated with a number of adverse health impacts. It is recognised as a contributing factor in the onset of heart disease and cancer. Additionally, air pollution particularly affects the most vulnerable in society: children and older people, and those with heart and lung conditions Areas with poor air quality are often less affluent and experience social and economic inequality (Ref 1 & 2).
The annual health cost to society of the impacts of particulate matter alone in the UK is estimated to be around £16 billion (Ref 1).
The Borough of Corby is located in the north-east of Northamptonshire in the East Midlands. The major conurbations of Leicester, Northampton and Peterborough are located to the north-west, south-west and north-east of the Borough, respectively.
The main pollutants of concern in Corby, as in most areas of the UK, are associated with road traffic, in particular NO2 and particulate matter (PM) at locations close to busy roads. The A43, A427 and the A6003 are the major routes that pass through the area. The countryside surrounding Corby is mainly rural in nature with arable farmland as the dominant form of agriculture.
Corby Borough Council uses a network of diffusion tubes at various locations throughout the Borough to monitor NO2 concentrations. The annual mean air quality objective for NO2 concentrations is 40µg/m (Ref 3); the Borough’s concentrations have consistently remained below the objective, and as a result, no Air Quality
Management Areas (AQMAs) have been declared within the Borough. NO2 diffusion tube monitoring results for the last 5 years (2014-2018) have been continually low. The 2018 results for urban background sites are consistent with the results of 2017 and show very little change. At roadside sites there is evidence of a slight increase in
2018 when compared to 2017. At present, no monitoring of pollutants PM10 and
PM2.5 is carried out within Corby Borough Council’s area.
Corby is experiencing rapid changes in both development and infrastructure. Whilst these changes are incredibly positive, they present future challenges with regards to managing air quality. As Corby currently experiences some of the best air quality in
LAQM Annual Status Report 2019 i Corby Borough Council
Northamptonshire, it is important that future development as a town does not impinge on this. Diffusion tubes were relocated in January 2019 to reflect shifts in traffic flow as a result of new housing and employment sites. Six new sites have recently been introduced, and consideration may need to be given to measuring PM10 and PM2.5 in the future.
Corby’s growth and regeneration continues to accelerate each year, providing more houses and employment opportunities. The diversity of the number of planning applications coming in each year underpins future Local Plans, Economic Development Strategies and Sustainability Strategies. All such development will have an impact on air quality, which needs to be considered. New potential sources of emissions include:
. Corby West is in the process of being developed, with over 4,500 homes being built over the next 15 years. The traffic coming and going from this site will undoubtedly have an effect on air quality. . The Midlands Logistic Park is due to be completed in the next few years. This large logistics development, located on land South of Geddington Road, is also likely to impact air quality in the borough. . Little Stanion is a major development located to the south east of Corby town. During 2018, a final phase was permitted for up to 135 dwellings. Works on this development are planned for the near future. A second development of 66 dwellings has been given detailed planning permission and works are imminent. . Oakley Vale is strategic development located to the south west of Corby town. This development has been in progress for a number of years and is reaching the final stages. In 2018, outline planning permission was given for 2 more phases of 530 dwellings and associated works. . Priors Hall Park is a sustainable urban extension located to the north east of Corby town which has been in development since 2010. It is located partially on the boundary with East Northamptonshire Council, and lies south of the former steelworks site. It is expected to be in development until beyond 2030 and is likely to have an effect on air quality. . Weldon Park is another sustainable urban extension, south of Priors Hall Park, consisting of 1000 new dwellings. Traffic improvements have been made to the A43 which separates the site, with the addition of a roundabout.
LAQM Annual Status Report 2019 ii Corby Borough Council
. Jackson’s bakery opened on Genner Road in Corby in 2018. . The closing of the coal fired power stations across the grid is putting more strain on energy supplies (gas fired power stations). Corby has a gas fired power station on Gretton Brook Road, on the north side of the town. . In the town centre, on Elizabeth Street/Market Walk, a new surface level car park opened. This car park replaced what was previously deposited demolition rubble and will potentially increase the number of cars visiting this end of Elizabeth Street.
Local authorities and the county council in Northamptonshire are currently working towards two unitary authorities following an announcement by the Secretary of State. By April 2021, Corby will be part of North Northamptonshire County Council alongside Kettering Borough Council, East Northamptonshire District Council and Wellingborough Council. These changes will undoubtedly affect the way that air quality is managed in the area.
Actions to Improve Air Quality
A new Local Plan for Corby is currently being developed, which will set out policies and proposals to guide future development in the Borough up to 2031. The Local Plan for the Borough is made up of two documents, the first of which is the North Northamptonshire Joint Core Strategy, adopted in July 2016 (Ref 6). This plan was created by the North Northamptonshire Joint Planning Unit, a partnership of Corby, East Northamptonshire, Kettering and Wellingborough Councils, together with Northamptonshire County Council. It sets out key plans for many strategic issues, including proposals for enhancing the environment.
The Council has started preparing the Part 2 Local Plan for Corby which will provide detailed planning policies to deliver the Part 1 North Northamptonshire Joint Core Strategy. Consultation on the plan occurred from July to August 2018 (Ref 7).
A core action to improve air quality was to encourage lower carbon transport alternatives and increase the proportion of low-carbon fuelled vehicles in Corby. By the end of 2018 the Council has added 10 electric and 1 hybrid vehicle to its fleet, which has enabled the authority to reduce fleet mileage and save 12 tonnes of carbon emissions in their first year on the road. Corby Borough Council have been
LAQM Annual Status Report 2019 iii Corby Borough Council awarded “GoLow”’s organisational status by OLEV (the Office for Low Emission Vehicles).
Corby Borough Council has also been working with taxi companies and licence holders to consider low carbon vehicles. In June 2018, taxi drivers in Corby began to swap their traditional diesel Hackney Carriages for London Electric Vehicle Company’s (LEVC’s) electric Hackney Carriage, the TX. This made Corby the first borough to have Low Emission Taxis outside of London, with 3 LEVC TX vehicles by November 2018. Corby Borough Council works with stakeholders to provide a fully functioning public Electric Vehicle Charging infrastructure, viewable on ZapMap. Members of the public can help improve air quality by switching their cars and vans to electric vehicles. Charging episodes have increased from 455 charges in 2014/15 to 3980 in 2018/19, which is a 775% increase in use. To further support the modal shift away from the private car, a Cycling Strategy was published for Northamptonshire and Corby. The Council continues to promote its cycle to work scheme for staff through VivUp. In addition, Corby Borough Council aims to place a bid for a Zephyr air quality sensor from the Northamptonshire County Council Public Health fund in the next financial year.
Conclusions and Priorities
NO2 concentrations in Corby have consistently remained below the objective, and as a result, no Air Quality Management Areas (AQMAs) have been declared within the Borough. Monitoring locations have remained the same since 1995. Since then, Corby has developed and its population has shifted and increased, meaning there are new areas in which air quality needs to be monitored. To reflect this, in January 2019 a selection of existing monitoring sites were relocated and six further sites introduced, increasing the network from 13 tubes to 17.
Corby Borough Council released a series of tweets on Clean Air Day 2018, aiming to educate members of the public on the issues surrounding air quality and pollution. In future years, Corby would like to hold a Clean Air event.
LAQM Annual Status Report 2019 iv Corby Borough Council Local Engagement and How to get Involved
If residents are considering swapping to an electric vehicle, the government offers up to 75% grant funding towards the cost of installing electric vehicle charge points at domestic properties through the Electric Vehicle Homecharge Scheme (EVHS). For information on how to apply, please see the gov.uk website. Employees can also apply for a charging point voucher at their place of work through the Workplace Charging Scheme. The voucher can enable a discount on up to 20 sockets, with up to £500 for each socket. For more information, please see the gov.uk website.
Corby also has a number of cycle routes, connecting key employment, leisure and residential areas. By getting on their bikes, members of the public can help to improve air quality whilst also improving their health. For more information, visit Cycle Northants. “Corby CycleFest” is an annual cycling festival held in Corby. For more information, or to take part, please contact Green Corby and keep up to date with the news section of the Council’s website.
Corby Borough Council also encourages members of the public to walk around Corby. There are several groups and organisations that provide useful resources and information. For more information, see Get Walking around Corby.
Employees in Corby can speak with their HR departments to find out if there are any lift sharing services available, either with other colleagues or employees of nearby workplaces.

LAQM Annual Status Report 2019 vii Corby Borough Council
1 Local Air Quality Management This report provides an overview of air quality in Corby during 2018. It fulfils the requirements of Local Air Quality Management (LAQM) as set out in Part IV of the Environment Act (1995) 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 an exceedance is considered likely the local authority must 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. This Annual Status Report (ASR) is an annual requirement showing the strategies employed by Corby to improve air quality and any progress that has been made.
The statutory air quality objectives applicable to LAQM in England can be found in Appendix E.
LAQM Annual Status Report 2019 1 Corby Borough Council
2 Actions to Improve Air Quality 2.1 Air Quality Management Areas
Air Quality Management Areas (AQMAs) are declared when there is an exceedance or likely exceedance of an air quality objective. After declaration, the authority must prepare an Air Quality Action Plan (AQAP) within 12-18 months setting out measures it intends to put in place in pursuit of compliance with the objectives.
Corby Borough Council currently does not have any AQMAs. The Stage 1 & 2 Air Quality Review and Assessment (Ref 4 & 5) concluded concentrations of any pollutants are unlikely to breach the Air Quality Objectives and therefore no AQMA was deemed necessary. For reference, a map of Corby Borough Council’s monitoring locations is available in Appendix D

2.2 Progress and Impact of Measures to address Air Quality in Corby
DEFRA remain satisfied with Corby’s ASR following the feedback received for the 2017 report. No further appraisal has been received to date.
Corby Borough Council has taken forward a number of direct measures during the current reporting year of 2018 in pursuit of improving local air quality. Details of all measures completed, in progress or planned are set out in Table 2.1.
Key completed measures are:
Support Northamptonshire County Council’s emerging Transport Plan, promote walking, cycling and public transport in order to support the modal shift away from the private car. A Cycling Strategy has been published for Northamptonshire and Corby.
Encourage lower carbon transport alternatives and increase the proportion of low-carbon fuelled vehicles in Corby. Corby Borough Council works with stakeholders to provide a fully functioning public Electric Vehicle Charging infrastructure. Charging episodes have increased from 455 charges in 2014/15 to 3980 in 2018/19, which is a 775% increase in use. Corby Borough Council have been awarded “GoLow”’s organisational status by the Organisation of Low Emission Vehicles. Work with taxi companies and licence holders to consider low carbon vehicles. The first Low Emission Taxi outside of London has been introduced to Corby.
Promote low carbon fleet and staff vehicle schemes in the business sector. Corby Borough Council is committed to “greening the fleet” and at the end of 2018 had 10 electric vehicles within the fleet and 1 hybrid vehicle.
Corby Borough Council expects the following measures to be completed over the course of the next reporting year:
Measure home energy conservation requirements as part of statutory Home Energy Conservation Act 1995. The report will be published in May 2019.
Corby Borough Council’s priorities for the coming year are to relocate existing monitoring sites and introduce six further sites, increasing the total number of sites
LAQM Annual Status Report 2019 3 Corby Borough Council from 13 to 17. This is to reflect Corby’s shifting and increasing population. In addition, Corby Borough Council aims to place a bid for a Zephyr air quality sensor from the Northamptonshire County Council Public Health fund in the next financial year.
The Council promoted Clean Air Day on 21st June 2018 by releasing a series of tweets. In future years, Corby would like to hold a Clean Air event. This will educate members of the public on the issues surrounding air quality and pollution.
The principal challenges that Corby Borough Council anticipates facing are the several new developments planned to begin construction. This increase in firstly construction traffic and ultimately population is set to have an effect on air quality for the area.

2.3 PM2.5 – Local Authority Approach to Reducing Emissions and/or Concentrations
As detailed in Policy Guidance LAQM.PG16 (Chapter 7), local authorities are expected to work towards reducing emissions and/or concentrations of PM2.5 (particulate matter with an aerodynamic diameter of 2.5µm or less). There is clear evidence that PM2.5 has a significant impact on human health, including premature mortality, allergic reactions, and cardiovascular diseases.
Although there are no specific measures targeting the reduction of PM2.5 currently, it is expected that the combination of actions that are currently in force or coming into force will help to bring about a reduction of PM2.5 (measures 1 - 4). However, discussions are being held with Public Health to devise policies that will specifically target the reduction of PM2.5.
LAQM Annual Status Report 2019 7 Corby Borough Council 3 Air Quality Monitoring Data and Comparison with Air Quality Objectives and National Compliance 3.1 Summary of Monitoring Undertaken
3.1.1 Automatic Monitoring Sites
Corby Borough Council does not undertake any automatic (continuous) monitoring.
3.1.2 Non-Automatic Monitoring Sites
Corby Borough Council undertook non- automatic (passive) monitoring of NO2 at 13 sites during 2018. Table A.1 in Appendix A shows the details of the sites.
Maps showing the location of the monitoring sites are provided in Appendix D. Further details on Quality Assurance/Quality Control (QA/QC) for the diffusion tubes, including bias adjustments and any other adjustments applied (e.g. “annualisation” and/or distance correction), are included in Appendix C.
3.2 Individual Pollutants
The air quality monitoring results presented in this section are, where relevant, adjusted for bias, “annualisation” and distance correction. Further details on adjustments are provided in Appendix C.
3.2.1 Nitrogen Dioxide (NO2)
Table A.2 in Appendix A compares the ratified and adjusted monitored NO2 annual mean concentrations for the past five years with the air quality objective of 40µg/m3. Annual mean concentrations for 2018 have been calculated using a weighted average due to exposure periods varying from the LAQM diffusion tube exposure periods recommended by Defra.
For diffusion tubes, the full 2018 dataset of monthly mean values is provided in Appendix B.
3 In 2018, NO2 concentrations were well below the annual mean objective (40µg/m ) for all monitoring sites. The highest recorded annual mean concentration in 2018 was 31.9 µg/m3 at site 2 (George Street).
3 Annual mean NO2 concentrations greater than 60 µg/m indicate a likelihood of exceedance of the 1-hour mean objective (200 µg/m3). As all sites in 2018 were well
LAQM Annual Status Report 2019 8 Corby Borough Council below this figure, it is highly unlikely that the hourly objective was exceeded at any location.
The 2018 results for urban background sites are consistent with the results of 2017 and show very little change. At roadside sites there is evidence of a slight increase in
2018 relative to 2017. Eight of the nine roadside sites showed an increase in NO2 3 concentrations, the largest increase was 7.4 µg/m at Site 4 (Elizabeth Street). NO2 concentrations have been well within the air quality objective for the last five years (2014-2018; see Table A.2).
From 2014 to 2015 there was a decreasing trend in NO2 concentrations, followed by all sites in 2016 experiencing an increase in NO2. In 2017, 11 of the sites experienced a decrease from 2016.
Across the five year period (Table A.2), the urban background locations (Sites 11 to 14) that are located in surrounding villages and away from the majority of local bus routes, consistently reported lower NO2 concentrations than the roadside sites within the administrative area, as would be expected.
On the basis of the latest monitoring results a number of changes are being introduced to the monitoring programme for 2019. There will be six new monitoring sites in total. The existing diffusion tube located on Willow Lane in Stanion is proposed to be relocated due to consistently low readings to the A43/A6116 roundabout to monitor changes in traffic to and from Little Stanion as this area has never been monitored. This site will also provide some insight on the emissions due to the Midlands logistic park, due to be completed in the next few years, which is in close proximity. Weldon Park consists of 1000 new dwellings. Traffic improvements have been made to the A43 which separates the site, with the addition of a roundabout. This is proposed to be a new diffusion tube site due to the changed traffic flow and increase in new receptors. This site is also located in close proximity with sites allocated for future development at Priors Hall Park.
To monitor the changes in NO2 emissions as Corby West develops, a new tube will be located on the junction of Danesholme Road with the A6003. In the plans for Corby West, this junction will be replaced with a roundabout which could increase the capacity of vehicular flow, but also idling time at peak hours.

Diffusion Tube Bias Adjustment
Bias adjustment is a calculated factor which shows whether diffusion tubes are over- or under-reading ambient concentrations relative to a particular reference point (i.e. a continuous monitoring station), allowing for an appropriate correction to be made.
As there is no co-location of diffusion tubes with a continuous analyser within Corby Borough Council’s area, the national bias adjustment factor (0.93) has been applied to the raw diffusion tube measurements. The factor was obtained from the National Diffusion Tube Bias Adjustment Factor Spreadsheet Version 03/19 Ref 8, for Gradko International using the 20% TEA in water method.
A list of the bias adjustment factors for 2014 to 2018 are summarised in Table C.1 below, and the derivation of the 2018 factor is shown in Figure C.1.
Table C.1 – National Diffusion Tube Bias Adjustment Factors Preparation Number of National Bias Year Method Studies Factor 2014 20% TEA / Water 22 0.92 2015 20% TEA / Water 30 0.87 2016 20% TEA / Water 32 0.92 2017 20% TEA / Water 39 0.87 2018 20% TEA / Water 30 0.93

Distance Corrections
Distance correction for NO2 fall off has been applied to the data where appropriate. Examples of the distance correction calculations are provided in Table C.3.
Table C.3 – Distance correction for NO2 fall off at Site 3 and Site 4
For Site 4 the receptor is more than 20 m further from the kerb than the monitoring site. Result should be treated with caution.
