Regulating COMAH - the COMAH Competent Authority

COMAH 2015 is enforced by a Competent Authority (CA) that comprises HSE, or the Office for Nuclear Regulation (ONR) for nuclear establishments, acting jointly with the appropriate environmental agency. In England this is the Environment Agency (EA), in Wales it is Natural Resources Wales (NRW); and in Scotland it is the Scottish Environment Protection Agency (SEPA). 

The CA Strategic Management Group

All five CA partner organisations work together through the CA Strategic Management Group (CASMG).This group looks across the CA and industry as whole, setting direction and regulatory priorities.

CASMG has agreed a purpose statement (PDF) [17] defining its collective aims to deliver a modern safety regime that seeks to protect people and the environment from major accidents occurring at COMAH establishments.

The CA working with industry - COMAH Strategic Forum and CDOIF

CA partner organisations also work with industry trade associations and other stakeholders to improve major accident hazard management and raise standards across industry. The COMAH Strategic Forum (CSF) and the Chemical and Downstream Oil Industries Forum (CDOIF) are two such partnerships with high level representation from the COMAH CA, industry and others. More information on CSF and CDOIF, current working groups and the guidance they have developed is available at the CSF (PDF) [18] and CDOIF (PDF) [19].
