Applicants will be able to apply for Additional Environmental Approval up until 31 December 2020. No Additional Environmental Approval may be granted or deemed to be granted after 31 December 2020 (except on an appeal lodged on or before that date). This means that, in order to be certain that a decision to grant or refuse Additional Environmental Approval will be made one way or the other (or that failing that Additional Environmental Approval will be deemed to be granted), applicants should submit applications no later than 2 December 2020. In practice, applicants should aim to submit comfortably in advance of that date, to allow time to resolve any issues as to whether sufficient information has been supplied and/or to allow the applicant and local planning authority to agree an extension to the determination period. Where an application is submitted after 2 December 2020, the local planning authority may still determine the application up to 31 December 2020. But there will be no deemed grant of Additional Environmental Approval if the local planning authority fails to do so. This is because, in those circumstances, there is not enough time for the 28-day period to elapse before 31 December 2020.
