LAQM.PG(22) – England (exc. London) Only

The revised policy guidance reflects the strengthened LAQM framework provided for by Schedule 11 of the Environment Act 2021 (the Act). This follows a consultation which ran for 10 weeks until 6 June 2022. Defra’s full government response to this consultation is available here. This is the first update to the LAQM policy guidance since 2016.

Key updates within LAQM.PG(22) include:

• Requiring local Air Quality Action Plans (AQAPs) to demonstrate how they will ensure that local Air Quality Objectives are met and maintained. AQAPs should set out a date by when each measure will be carried out. Air Quality Action Plans that do not fulfil these criteria will need to be revised.
• The requirement for an Air Quality Management Area to be declared within 12 months of identifying an exceedance of the air quality objectives.
• The requirement for local authorities to produce an Air Quality Action Plan within 18 months of declaring an Air Quality Management Area.
• The introduction of a system of reminder and warning letters to increase local authority compliance with reporting.

LAQM.TG(22) – UK (exc. London) Only

The new version of the technical guidance corresponds to updates in the latest version of the LAQM Policy Guidance for England.  While the main changes within this version of the technical guidance are in relation to new English Policy Guidance, the Welsh, Scottish and Northern Irish Devolved Administrations have provided inputs and included updates throughout, where relevant.

Key updates within LAQM.TG(22) include:

• Updated section relating to process for consultation, steering groups and engaging with Relevant Public Authorities (RPAs) to support the updated Policy Guidance in producing Air Quality Action Plans to the required standard.
• In England and Wales, the Fast-track option has been removed and now authorities must declare an AQMA within 12 months of an identified exceedance or risk of exceedance. The flow chart detailing the process for declaring, amending and revoking AQMAs has been updated in light of these changes.
• Updated study on assumptions for exceedances of short term NO₂ objectives. The updated study has affirmed the existing assumption that, at concentrations above 60µg/m³ as an annual average, there is the potential for exceedances of the 1-hour objective.
• Updated study on relationship of PM₁₀ and PM_2.5 for the purpose of estimating PM_2.5 concentrations where only PM₁₀ monitoring is available. Going forward, two separate factors will be calculated on an annual basis for background and roadside sites by analysing data from the AURN.
• From 2023 in England, Local Authorities are required to produce an Air Quality Strategy where they have no declared AQMAs.
• A worked example of model verification for modelling of road emissions.
• Clarified section on diffusion tube deployment and siting.
• Discussion around use of diffusion tubes with wind caps, including the process for bias adjustment for these different tube types.
• Further clarity is provided for completion of source apportionment where detailed modelling has not been completed.
• Inclusion of potential mitigation processes for non-transport sources.

Designation of National Highways as a ‘relevant public authority’ – England (exc. London) Only

The Environment Act 2021 introduces the concept of ‘Air Quality Partners’ – including neighbouring local authorities and the Environment Agency as well as designated ‘relevant public authorities’.

Following consultation which ran for 10 weeks until 6 June 2022, we are also announcing today that the Government will designate National Highways as a ‘relevant public authority’.  We aim to lay the designation SI in the Autumn.  Defra’s full government response to this consultation is available here.

This change will require National Highways to collaborate with local authorities to improve air quality – becoming an ‘air quality partner’ where locally relevant.  We also consulted on guidance on working with air quality partners and specific guidance on working with National Highways.  This will be published alongside the LAQM policy guidance once National Highways is legally designated. However, the draft that was consulted on can be accessed and viewed now here at Annex A.

Local authority air quality officers are asked to:

• Familiarise yourselves with the new statutory guidance and legislation.
• Bring these changes to the attention of others in your local authority (and upper tier authorities where relevant) who should be aware of the strengthened LAQM framework.
• Consider which additional public authorities (bodies with functions of a public nature that could affect the quality of air) should be considered for designation as a “relevant public authority”.
• Review and revise AQAPs as necessary.

Local Authority Dashboard – England (exc. London) Only

The local authority dashboard has been developed to add additional capabilities to the existing LAQM portal. The dashboard has been populated with the following information unique to each individual local authority:

• Helpdesk Enquiries: Local authorities are able to check enquiries they have made to the Helpdesk and keep track of any ongoing queries.
• Reporting: Any overdue annual reports or missing information is highlighted to authorities to help them keep up to date with their reporting requirements.
• AQMAs: Headline AQMA data is available on the dashboard as a helpful summary.
• Monitoring: The diffusion tube monitoring data for your local authority is presented as interactive maps and graphics showing site types, number of sites which are exceeding and the trends in NO₂ annual mean concentrations over time to assist in development of Annual Status Reports and inform any updates to the diffusion tube programme.
• AQAPs: A list of AQAPs associated to AQMAs is presented. This provides clear guidance to local authorities to ascertain which AQMAs are missing AQAPs, as well as the AQMAs which require an updated AQAP to be published.

11 August 2022

LAQM Portal User Guide

A user guide for local authorities accessing the LAQM Portal has been published. This provides instructions for the submission of Annual Reports, AQAPs, Diffusion Tube Data (England exc. London Only), alongside submitting AQMA changes and Detailed Assessments.
