These Regulations apply to damage to protected species, natural habitats, sites of special scientific interest, water and land. They implement Directive 2004/35/EC of the European Parliament and of the Council on environmental liability with regard to the prevention and remedying of environmental damage and provide that, for certain economic activities, where there is an imminent risk of environmental damage, the operator must take steps to prevent it, and if it has occurred must prevent further damage. Where damage has occurred the enforcing authority must assess the damage and identify remedial measures. It must then serve a remediation notice on the responsible operator specifying what remediation is required. The Regulations also provide with respect to other matters of enforcement and define offences.
