The emergency drought response account is created in the state treasury. All receipts from moneys received pursuant to RCW 43.83B.406, moneys appropriated to the account by the legislature for the purpose of funding emergency drought response actions or moneys directed to the account from any other lawful source must be deposited into the account. Moneys in the account may be spent only after appropriation. Expenditures from the account may be used only for the costs of implementing the powers set forth in RCW 43.83B.410 through 43.83B.420 to provide relief for the immediate hardship caused by water unavailability while a drought emergency order issued pursuant to RCW 43.83B.405(2) is in effect. The department must, at a minimum, provide the director of the office of financial management, legislative fiscal committees, and the joint legislative committee on water supply during drought, established under RCW 90.86.010, with a close-out cost summary following the expiration of an emergency drought order during which expenditures were made from the account.
