We provide advice on proposed developments and activities located in Welsh Territorial Waters out to the 12 nautical mile boundary.

We also provide advice on development plans and programmes which apply in these waters, and the Strategic Environmental Assessment (SEA) and Habitats Regulations Assessments (HRA) prepared in support of these plans.

We work in collaboration with JNCC, the Environment Agency and other relevant statutory bodies where there may be trans-boundary effects.

NRW also issues ’marine licences’ under the Marine and Coastal Access Act 2009 on behalf of Welsh Ministers. These apply for certain activities proposed within Welsh Territorial Waters.
