Unpleasant odours can cause complaints, disrupt communities, and lead to regulatory action. For industries that produce emissions or waste, conducting an Odour Impact Assessment (OIA) is often essential to comply with planning conditions, environmental permits, and local authority requirements.
But what is an odour impact assessment, who needs one, and why is it important?
What Is an Odour Impact Assessment?
An OIA evaluates the presence, concentration, and impact of odours generated by a site or activity. It identifies potential odour sources, predicts how far odours may travel, and provides mitigation strategies to minimise complaints and regulatory breaches.
A professional OIA includes:
-
Baseline odour surveys to measure current conditions.
-
Odour dispersion modelling to predict odour movement and intensity.
-
Source identification (e.g., waste storage, chemical processing, food production).
-
Odour mitigation plans (covering storage, ventilation, and containment).
Who Needs an Odour Impact Assessment?
Industries or sites that frequently require OIAs include:
-
Food processing and production facilities.
-
Waste management and recycling plants.
-
Agricultural operations (manure, silos, slurry).
-
Landfills and composting sites.
-
Chemical manufacturing and storage facilities.
If your operation has the potential to generate odours beyond your site boundary, local authorities or the Environment Agency (EA) may require an OIA.
Why Are Odour Assessments Important?
-
Planning Applications: Many councils require an OIA as part of planning approval for new or expanding facilities.
-
Permit Compliance: Odour management is a condition under many environmental permits.
-
Avoiding Complaints: Uncontrolled odours can lead to neighbour complaints, enforcement action, or fines.
-
Reputation Management: Proactive odour control reduces conflict and improves community relationships.
What Happens If You Ignore Odour Risks?
Without an OIA or mitigation plan, you risk:
-
Planning delays or rejections.
-
Enforcement notices from local councils or the EA.
-
Costly operational restrictions or legal action.
