Residual market mechanisms shall file with the commissioner all rates, supplementary rate information, supporting information, policy forms, and endorsements at least thirty (30) days before the proposed effective date. The commissioner may give written notice within thirty (30) days of the receipt of the filing that additional time, not to exceed thirty (30) days from the date of such notice, is necessary to consider the filing. Upon written application by the residual market mechanism, the commissioner may authorize rates to be effective before the expiration of the waiting period or an extension thereof. A filing is deemed to meet the requirements of this chapter and becomes effective unless disapproved by the commissioner before the expiration of the waiting period or an extension thereof. Whenever a filing made under this section is not accompanied by sufficient supporting information, the commissioner shall inform the filing entity as to what information is required to complete the filing. The filing shall not be deemed to be made until such information is furnished.
