Systematic Assessments
Ensuring Environmental Risk Is Understood, Quantified and Managed
Systematic assessments are a cornerstone of environmental permit compliance. They help operators identify, evaluate and mitigate risks to air, water, land and receptors—ensuring that operations meet regulatory expectations under the Environmental Permitting Regulations (EPR).
Arthian provides:
- H1 risk assessments for bespoke and standard permits
- Air emissions and dispersion modelling
- Groundwater and surface water pollution risk assessments
- Waste recovery and disposal method evaluation
- Integration with BAT, ERA and COMAH Safety Reports

Frequently Asked Questions
What is a systematic assessment?
It’s a structured evaluation of environmental risks—covering emissions, discharges, waste and receptor impacts—to support permit compliance and operational safety.
Do I need a systematic assessment for my permit?
Yes—especially for bespoke permits, variations, or when responding to Regulation 61 notices. It’s essential for demonstrating ALARP and BAT alignment.
Can I use my own modelling tools?
You can, but regulators prefer standardised outputs. We help translate bespoke models into regulator-friendly formats using H1, ADMS, and J5 tools.
