Greater Manchester Clean Air Plan privacy policy

Updated April 2022

The Greater Manchester Clean Air Plan

In July 2017, the UK government published the UK plan for tackling roadside nitrogen dioxide (NO2) concentrations. The plan sets out several national and local measures that needed to be taken, including the development by local authorities of local plans to tackle the causes of air pollution.

In March 2020, the government instructed all ten Greater Manchester (GM) councils (Bolton, Bury, Manchester, Oldham, Rochdale, Salford, Stockport, Tameside, Trafford and Wigan) to introduce a charging Clean Air Zone (CAZ) to tackle harmful levels of air pollution and achieve compliance with legal standards by 2024 at the latest. This direction has now been withdrawn and means that the GM Clean Air Plan (GM CAP) measures that had been approved by the GM local authorities after the statutory consultation, including a GM-wide CAZ Category C Zone, are under review.

A new government direction dated 8th February 2022 requires the 10 GM local authorities to bring nitrogen dioxide on local roads to within legal limits as soon as possible and by no later than 2026 and to work with government to develop a new plan that will clean up our air while protecting livelihoods by the 1 July 2022.

Each of the GM Local Authorities has via a delegation approved that the Greater Manchester Combined Authority (GMCA) (acting by its officer, Transport for Greater Manchester (TfGM)) is authorised to undertake arrangements that need to be undertaken to deliver the GM CAP on behalf of the 10 GM Local Authorities in accordance with TfGM’s existing constitutional arrangements.

For more information on Clean Air Zones please visit the GOV.UK clean air zones guidance page. This is separate to the GM Clean Air Financial Support Scheme.

GM Clean Air Plan privacy notice

The GM CAP privacy notice supplements TfGM’s general privacy notice and explains how we will process and share personal data for the purposes of the GM CAP.

TfGM and the ten GM local authorities are a joint data controller with the Joint Air Quality Unit (JAQU) and for personal data processed by JAQU, who are a joint unit of the Department of Transport (DfT) and the Department for Environment, Food and Rural Affairs (Defra) which is overseeing the UK plan for tackling roadside NO2 concentrations.

On behalf of the 10 GM LA’s TfGM has procured Egis Projects SA as a data processor to deliver the GM CAZ service.

This privacy notice deals with the personal data that TfGM processes to deliver the GM CAP, and what information is shared with JAQU as joint controllers. Should you wish to know more about how JAQU processes and shares your personal data please refer to its privacy notice.

What personal data is being collected and how is it used?

Customer contact centre

If you phone the Customer Contact Centre, to make any enquiries concerning GM CAP, the following information may be requested from you to provide resolution to queries and support:

  • First name
  • Surname
  • Phone number
  • Email address
  • Address
  • Postcode

Vehicle Registration Numbers (VRNs) and Automatic Number Plate Recognition (ANPR) Cameras

The ANPR cameras installed for the GM CAP will be utilised, to better understand the current vehicle fleet on Greater Manchester’s roads and their emissions. This will help GM understand how vehicle fleets have naturally renewed over the development of the GM CAP. Where ANPR cameras are next to air quality monitoring stations, we can also analyse and understand how specific vehicle types might be contributing to overall emissions.

TfGM together with GM LAs is the joint data controller for data processed by the ANPR cameras. The cameras are supplied and operated by Yunex Traffic who are a sub-processor of Egis who process this information on behalf of TfGM.

TfGM does not have access to the details of registered keepers of the vehicle images captured on the ANPR cameras which collect the following data:

  • Vehicle Registration Numbers (VRNs) captured by ANPR images
  • Images of the immediate area
  • Dates, times and location of vehicles captured

VRN details will be used to obtain vehicle types and emission data which will be matched by the DVLA on behalf of JAQU before being sent back to TfGM fully anonymised and TfGM will not be able to identify registered keepers of vehicles.

Your VRN will also be collected if you use the government vehicle checker to check if a vehicle is compliant. This is operated by JAQU which will be the data controller of this information. You can access further information in relation to the vehicle checker by going to the GOV.UK website and reviewing JAQU’s privacy notice.

Who will we share your information with?

In order to inform the GM CAP review with government, information may be lawfully shared with the following for further evaluation and reporting:

  • Suppliers working with or on behalf of TfGM who are processing information on behalf of TfGM for testing purposes and informing the new GM CAP.
  • Other government departments such as the DfT, the DVLA and JAQU.
  • Other GM Local Authorities.

Should the GM authorities agree that a CAZ is to be included in any revised GM CAP, then for the purposes of operating a CAZ information will be shared with other third parties in order to confirm compliance with any CAZ requirements. This will include JAQU, and the DVLA.

Data sharing agreements are in place for the sharing of this information and further agreements or variations may be required as the project progresses.

We may need to share some personal information with other third parties who are assisting us to deliver the GM CAP. Further privacy notices will be available for the sharing of this information.

This privacy notice will be updated as the GM Clean Air Plan progresses, and we will provide you with a new privacy notice when we make any substantial updates.

It may also be necessary for TfGM to share information with the Police and/or other law enforcement agencies for the purpose of crime prevention or detection.

NO2 evaluation data

In order for TfGM and JAQU to assess and monitor information to inform the GM CAP, TfGM needs to gather ‘real time’ data and understand the type of vehicles travelling on local roads within the GM administrative boundary to develop a new plan that will clean up our air while protecting livelihoods.

TfGM therefore may share VRN details with JAQU throughout this monitoring and evaluation period. This will then be matched by DVLA on behalf of JAQU with vehicle type and emissions data before being sent back to TfGM. This data will then be anonymised.

DfT will retain the data in a pseudonymised format for no longer than 12 months from receipt of the information.

Under what legal basis does the processing of personal data take place?

The UK General Data Protection Regulation (GDPR) and Data Protection Act 2018 provide for several different legal bases under which processing of personal data may take place. In relation to the processing of the personal data for the GM CAP contact centre following basis applies:

  • Article 6 (1)(e) processing is necessary for the performance of a task carried out in the public interest and in the exercise of official authority vested in DfT and Defra as partners in JAQU and TfGM and the local authorities to deliver a new Clean Air Plan.

For any special category personal data that may be processed the lawful basis is:

  • Article 9(2)(g) of the UK GDPR (processing is necessary for reasons of substantial public interest and is authorised by domestic law (see section 10 of the Data Protection Act 2018).

In relation to the processing of VRMs using the ANPR cameras the following legal basis applies:

  • Article 6 (1) (c) processing is necessary for compliance with a legal obligation.

How long is information kept for?

The information collected to monitor and inform the new plan is kept for the minimum period necessary to fulfil the purposes it is collected it for. Information will not be kept for longer than necessary.

Any images captured on ANPR cameras are kept for a maximum of 14 days in line with the Clean Air Zone Certification of Approved Devices [CoAD] issued by the Vehicle Certification Agency [VCA]. The VCA is an executive agency, sponsored by the DfT.
