Applicants should ensure that all material which is likely to be relevant is included within the application for Additional Environmental Approval. Further substantive information should not be submitted during the determination period. The local planning authority is entitled to sufficient information at the start of the 28-day period. If during the determination period it becomes apparent that the local planning authority cannot determine whether the EIA and Habitats requirements are met without further substantive information from the applicant, the authority should refuse Additional Environmental Approval. An applicant may then make a new application for Additional Environmental Approval containing further information so that the authority can deal with it in a fresh 28-day period.
