The Control of Major Accident Hazards Regulations 2015 (COMAH 2015), SI 2015/483, aim to prevent major work place accidents occurring and put in place controls, so that should an accident happen, the effects on people and the environment are mitigated.

COMAH 2015 works by setting out basic duties that all obligated sites/businesses must abide by and also provides a tiered system, with stricter controls, for those businesses handling quantities of dangerous substances over the designated thresholds.

Brexit impact

This content is likely to be impacted by the UK’s withdrawal from the EU. For information on how leaving the EU will affect environmental law, see Practice Note: Brexit—environmental law implications, which details the relevant aspects of the withdrawal process, as well as providing insights into developments affecting environmental protection, such as the draft Environmental Principles and Governance Bill.

The date and time of withdrawal of the EU (exit day) is specified in UK law (under section 20 of the European Union (Withdrawal) Act 2018), but until the legal terms of the withdrawal negotiated with the EU are finalised, there remains a possibility that the UK’s membership will lapse automatically on exit day, without all the necessary legal and transitional arrangements in place. This has implications for practitioners considering specific environmental law regimes. For information on no deal guidance for these regimes, see Practice
