If the director believes that the payment to the state of the trust fund established under § 28-40-3.1 will be jeopardized by delay, neglect, or misappropriation, he or she shall then notify the employer that the trust fund shall be segregated, and be kept separate and apart from all other funds and assets of the employer and shall not be commingled with any other funds or assets. That notice shall be given by either hand delivery or by registered mail, return receipt requested. Within four (4) days after the sending of that notice, all taxes that subsequently either become collectible or are collected shall be deposited weekly in any financial institution in the state and those contributions shall be designated as a special fund in trust for the state and payable to the state by the employer as trustee of that fund.
