The legislation requires that sufficient information be provided with the application to allow the local planning authority to reach a decision as to whether Additional Environmental Approval should be granted. The local planning authority should first form a view on whether it has sufficient information. It should do as soon as practicable after receiving the application. If the local planning authority considers that insufficient information has been provided, then it should write to the applicant explaining that the application as submitted does not comply with the legislation, and the authority is accordingly unable to entertain the application, unless and until sufficient information is provided. If the applicant then submits further information to the local planning authority, such that the information submitted as a whole is sufficient, then the local planning authority should go on to determine the application. In this case, the determination period (28 days or as extended by agreement) will only begin to run from the date on which sufficient information was sent.
