Detailed description
If you construct, operate or modify a facility that does not require a permit and is part of an operating area and the effects are relevant to a major accident, you require a permit.
If, when reviewing your previous notification of a construction or modification relevant to a major accident, the competent authority determines that your project has implications under major accident law, a permit is also required.
These projects may result in the plant posing a significant risk or other requirements under emissions law no longer being met.
