Feedback and the application process

Due to its scale, the project is classified as a nationally significant infrastructure project (NSIP) under the Planning Act 2008 and the application will be determined by the Government.

Later this year (2022) we intend to submit our proposals to the Planning Inspectorate, the Government body responsible for handling NSIP applications. The Planning Inspectorate will carry out an examination of the proposals and make a recommendation to the Secretary of State who will make the final decision.

Local councils, stakeholders and residents have an important role to play through this process. All written comments we receive will be considered and reported as part of the application process.  

Please note, comments may be made public and the personal details of respondents may be made available to the Planning Inspectorate and other third parties
