Paragraph 6 I1

In the event of any disapproval of plans by a highway authority under paragraph 4, the undertaker may re-submit the plans with modifications and, in that event, if the highway authority has not intimated its disapproval and the grounds of disapproval within 21 days of the plans being re-submitted, it is to be deemed to have approved them except to the extent that the plans involve departures from Highways Agency and local highway authority standards.
