Environmental Risk Assessments (H1, SCAIL, D1)

What the Risk Assessment Typically Covers

Depending on scope and activity, an Environmental Risk Assessment can include:

• Emissions to air screening and/or modelling support (linked to Dispersion Modelling)
• Stack height justification where required (see H1 Stack Height Determination)
• Surface water discharge risk assessment where relevant to bespoke permit applications
• Odour risk assessment and management controls (see Odour Management Plans)
• Noise risk assessment where required by receptors and permit conditions
• Accident and incident risk (spills, firewater runoff, abnormal operation scenarios)

How Environmental Risk Assessments Work in Practice

We structure risk assessments around regulator decision-making: clear scope, clear inputs, transparent assumptions, and a controlled output format. Where risks cannot be screened out, we define what additional evidence is required (e.g., dispersion modelling, monitoring proposals, management plans) and ensure mitigation is practical and auditable.

Standards, Guidance and Regulatory Context

Environmental permit risk assessments commonly align to GOV.UK Risk assessments for your environmental permit, Risk assessments for specific activities, ADMLC H1 Risk Assessment Tool, Surface water pollution risk assessment, and SCAIL screening tools for habitat deposition screening where relevant.

What the Service Delivers

• A structured risk assessment aligned to your permitting objective and site context
• Clear identification of sources, pathways and receptors with risk conclusions
• Screening outputs and justification (or clear rationale for detailed assessment)
• Mitigation, monitoring and management controls that are practical and auditable
• A permit-ready report format suitable for regulator engagement

Limitations and Scope

Risk assessments depend on data quality and representativeness. Where inputs are uncertain or operations vary materially, we make assumptions explicit and recommend proportionate sensitivity testing or additional evidence to improve defensibility.
