Odour Dispersion Modelling
What It Is
Odour Dispersion Modelling uses computer simulations using ADMS6 to predict how odours from a site will disperse into the surrounding environment. By combining site-specific emissions data with meteorological conditions, it assesses the risk of odour nuisance at nearby sensitive receptors such as homes, schools, or workplaces. This evidence is often required to support planning applications, Environmental Permit applications, or odour management plans.
Why It Matters — Risks Without It
- ❌ Planning refusal or permit rejection if odour impacts are not assessed
- ⚠️ Complaints and enforcement action from local authorities or the Environment Agency
- 📣 Damage to reputation with communities affected by odour nuisance
- 🧾 Costly retrofits or operational restrictions imposed after approval
What’s Measured
- Odour emission rates from sources such as stacks, tanks, or open surfaces
- Meteorological conditions (wind speed, direction, temperature, stability)
- Predicted odour concentrations at receptor locations
- Frequency and intensity of potential odour nuisance events
- Compliance against Environment Agency and planning thresholds
How It Works
- Data Collection: Gather emission rates, site layout, and operational details.
- Model Setup: Apply advanced dispersion models such as ADMS or AERMOD.
- Simulation: Run meteorological and emissions data to predict odour impacts.
- Assessment: Compare model results against odour impact criteria (e.g. EA H4 Guidance).
- Reporting: Provide a regulator-ready technical report with clear evidence and recommendations.
