(b) The petition must contain a concise statement of the basis for seeking review, including any specific factual or legal error alleged. If the petition requests consideration of information that was not previously made available to the Chief Counsel, the petition must include the reasons why such information was not previously made available.
(c) The petitioner shall mail a copy of the petition to each person who participated, either as an applicant or commenter, in the waiver of preemption proceeding, accompanied by a statement that the person may submit comments concerning the petition to the Chief Counsel within 20 days. The petition filed with the Chief Counsel must contain a certification that the petitioner has complied with this paragraph and include the names and addresses of all persons to whom a copy of the petition was sent. Late-filed comments are considered so far as practicable.
