The petition shall state that it is a petition for reconsideration of a final rule, and shall contain an explanation as to why compliance with the rule is not practicable, is unreasonable, or is not in the public interest. If the petitioner requests the consideration of additional facts, the petitioner shall state the reason they were not presented to be treated as petitions for rulemaking.

All interpretative bulletins shall be indexed and made available to the public at the Manufactured Housing Standards Division and a copy of the index shall be published periodically in the Federal Register.
