(1) An applicant for a Class A or B license must submit to the executive secretary at the time of application a certified check or bank draft to the order of the state of Washington in the amount of fifty thousand dollars to cover the costs of the investigation mandated by these rules. Upon completion of the investigation, the commission must refund to the applicant any amount by which the fifty thousand dollars exceeds the actual costs of investigation. If costs of the investigation exceed fifty thousand dollars, the applicant must remit the amount of the difference by certified check or bank draft within ten days after receipt of a bill from the commission. Should an applicant fail to pay additional amounts when billed, the commission will suspend all further action or investigation on the application until receipt of all moneys due and owing. The commission may, at its discretion, require an additional amount by way of deposit if necessary to complete its investigation. An individual or other entity applying for Class A and B licenses simultaneously must submit only one fifty thousand dollar investigation fee.

(2) An applicant for a Class C license is not required to pay an investigation fee set forth in subsection (1) of this section.
