If the Board finds the petition fails to contain information required by Section 104.406, the Board may order the petitioner to supplement the information contained in the petition through its own order or through a hearing officer order. Filings made in response to the order constitute an amended petition and will be subject to requirements of Section 104.418. Alternatively, under Section 104.414, the Board may dismiss the petition for lack of sufficient information. Failure of the Board to require supplemental information does not preclude a later finding that the information provided is insufficient to support grant of an adjusted standard, or constitute a Board decision on the merits of the petition.
