Choosing a Representative Meteorological Station for UK Dispersion Modelling
The nearest met station is rarely the most representative. What a representative station actually looks like, and how to structure the choice so that it stands up to local-authority scrutiny.
IAQM 2024 V2.2 Dust Methodology: What Actually Changed
A practitioner’s walk-through of what actually changed in the IAQM 2024 V2.2 dust guidance, and what the update means for live and forthcoming construction projects.
Quick answers to the questions we’re asked most often by planning consultants, developers and operators.
When does my development need an air quality assessment?
An air quality assessment is typically required where a development sits within or adjacent to an Air Quality Management Area (AQMA), where it generates significant additional traffic, where it introduces new sensitive receptors near busy roads or industrial sources, or where the local planning authority has attached a planning condition requesting one. The IAQM/EPUK guidance and the relevant Local Plan policy will normally clarify the trigger thresholds for your area.
What is the difference between an air quality assessment and a dust impact assessment?
An air quality assessment looks at the operational phase of a development, focusing on long-term pollutants such as nitrogen dioxide and PM10/PM2.5 from traffic, combustion plant or industrial sources. A dust impact assessment (DIA) is a separate construction-phase exercise following the IAQM 2024 V2.2 methodology, which evaluates the risk of nuisance dust from demolition, earthworks, construction and trackout. Many planning applications require both: the AQA for operational impacts, and the DIA for the construction phase.
How long does an air quality assessment take?
A screening-level assessment is typically completed within 1 to 2 weeks. A detailed assessment involving ADMS-Roads dispersion modelling normally takes 3 to 4 weeks from receipt of traffic data, although bespoke baseline monitoring (where required) can extend the programme to 12 weeks or more. We advise on realistic programmes at the quote stage and can prioritise urgent work where planning timetables demand it.
How much does an air quality, dust or odour assessment cost?
Costs vary by complexity. Air quality screening assessments start from £850, detailed dispersion modelling assessments from £1,500, dust impact assessments from £600, and EMAQ+ kitchen odour assessments from £800. Every project is different, so we provide a clear, transparent fixed-fee quote following a brief initial conversation about your requirements.
What are your qualifications?
Air Dust Odour is led by Malcolm Pounder, a Chartered Environmentalist (CEnv), Full Member of the Institution of Environmental Sciences (MIEnvSc) and a Member of the Institute of Air Quality Management (MIAQM). Assessments are delivered in accordance with the current IAQM, EPUK, LAQM and Environment Agency guidance.
Do you work across the whole UK?
Yes, we provide air quality, dust and odour assessment services across England, Scotland, Wales and Northern Ireland. Most of our work is delivered remotely from our office in Seaham, County Durham, with site visits and bespoke monitoring deployed where required.
