(c) An applicant for an exemption must notify interested persons in the event that the Department schedules a hearing on the exemption. Such notification must be given in the form, time, and manner prescribed by the Department. Ordinarily, however, adequate notification can be given by providing to interested persons a copy of the notice of hearing published by the Department in the
Federal Register within 10 days of its publication, using any of the methods approved in
§ 2570.43(c) of this part.
