• Inspection of bunds and containment systems. This includes inspection and reporting in accordance with industry good practice guidance (CIRIA C736).

• Compliance assessment of existing facilities. This includes assessing the existing performance vs the COMAH Competent Authority requirements

• Upgrade/remediation of existing containment systems. This includes increasing height, repairing bund penetrations, specification of appropriate sealants and joints, repairing burrowing and other bund defects.
• New build secondary containment. This includes concrete bunds, lined earth bunds, leak detection, transfer systems, drainage and remote storage solutions.

• Tertiary containment modelling. Modelling of spills and design of upgrade mitigation measures to contain over-topping. This includes overland flow modelling.

• Volumetric modelling. 3D surveying (or scanning) to identify ground profiles. Calculation of bund volumes for compliance checks, assessment and remediation

Environmental Risk Assessment (ERA) Expertise for COMAH Compliance

Operating COMAH (Control of Major Accident Hazards) sites comes with the responsibility to prevent or mitigate potential Major Accidents To The Environment (MATTE). Ensuring compliance with COMAH regulations necessitates the execution of an Environmental Risk Assessment (ERA) following the guidance provided by the Chemical and Downstream Oil Industries Forum (CDOIF).

Our environmental consultants are well-versed in the CDOIF methodology, having provided support to numerous COMAH clients across diverse industrial sectors. We’ve successfully guided them through assessments, aligning with the ‘Environmental Risk Tolerability for COMAH Establishments’ guidance document, acknowledged as the benchmark standard by the COMAH Competent Authority.
