RCW 48.19.043(2) says an insurer must file rates within thirty days after the date the insurer first uses them. If the commissioner rejects a filing under WAC 284-24-016, the insurer has not filed rates with the commissioner. If the commissioner rejects a filing submitted under RCW 48.19.043, the:

(1) Filer must promptly send a new rate filing to the commissioner within the original thirty-day use and file period in RCW 48.19.043(2); or

(2) Insurer must stop using the rates sent with the rejected filing and amend policies using approved rates.
