3.

7. Any other provision of this section to the contrary notwithstanding, the department, board, or commission referenced in subsection 1 of this section may adopt a rule without conducting a regulatory impact report if the director of the department determines that immediate action is necessary to protect human health, public welfare, or the environment; provided, however, in doing so, the department, board, or commission shall be required to provide written justification as to why it deviated from conducting a regulatory impact report and shall complete the regulatory impact report within one hundred eighty days of the adoption of the rule.
