Need help? Ask our experts a quick question on COMAH Flood Preparedness

COMAH operators in flood risk areas have a legal requirement to comply with the Operational Delivery Guide – Inspection of COMAH Operator Flood Preparedness. The Operational Delivery Guide is aimed at both upper and lower tier COMAH establishments where flooding could directly initiate a Major Accident to the Environment (MATTE), or where flooding may prevent an emergency response to an on-site major accident. The Chemical and Downstream Oil Industries Forum (CDOIF) – Preparing for a Flood: Guidance and Best Practice also outlines similar requirements.

Flood Preparedness Assessment

Flood Preparedness Assessment / Flood Impact Assessment

Using Ashfield’s extensive flood risk and environmental expertise, the Flood preparedness inspection route would be followed as per the Operational Delivery Guide, resulting in an all-encompassing report. This would lead to establishing the level of flood risk that is posed to a site, broken down into each vulnerable asset which if flooded may lead to causing a Major Accident. Ashfield would utilise the most up to date flood modelling information, coupled with suitably detailed topographical and critical asset data to verify whether flooding should be deemed an issue on site.

Flood Action Plan / Flood Response Plan

Where flooding has been confirmed as a risk that could potentially lead to causing a Major Accident, Ashfield is able to work with you to outline the most suitable preventative measures, as well as develop an Action Plan that can be implemented should flooding be predicted to occur in future.

Ongoing Support and Representation

Ashfield understands that sites operating under COMAH regulations are dynamic, which often includes the upgrading of equipment or changes in operational layout over time. Flood prediction methods are also continually improving, as well as the potential further impacts that may come when considering Climate Change. To ensure that your site is futureproof, we often provide our clients with ongoing support in ensuring their understanding of flood risk on site is current and based upon the best available information.
