(1) A tax is imposed on the privilege of possession of petroleum products in this state. The rate of the tax shall be thirty one-hundredths of one percent multiplied by the wholesale value of the petroleum product. After July 1, 2021, the rate of tax is fifteen one-hundredths of one percent multiplied by the wholesale value of the petroleum product. For purposes of determining the tax imposed under this section for petroleum products introduced at the rack, the wholesale value is determined when the petroleum product is removed at the rack unless the removal is to an exporter licensed under chapter 82.38 RCW for direct delivery to a destination outside of the state. For all other cases, the wholesale value is determined upon the first nonbulk possession in the state.

(2) Except as identified in RCW 70A.345.130, moneys collected under this chapter shall be deposited in the pollution liability insurance program trust account under RCW 70A.325.020.

(3) Chapter 82.32 RCW applies to the tax imposed in this chapter. The tax due dates, reporting periods, and return requirements applicable to chapter 82.04 RCW apply equally to the tax imposed in this chapter.

(4) Within thirty days after the end of each calendar quarter the department shall determine the "quarterly balance," which shall be the cash balance in the pollution liability insurance program trust account as of the last day of that calendar quarter, after excluding the reserves determined for that quarter under RCW 70A.325.020(2). Balance determinations by the department under this section are final and shall not be used to challenge the validity of any tax imposed under this section. For each subsequent calendar quarter, tax shall be imposed under this section during the entire calendar quarter unless:

(a) Tax was imposed under this section during the immediately preceding calendar quarter, and the most recent quarterly balance is more than fifteen million dollars; or

(b) Tax was not imposed under this section during the immediately preceding calendar quarter, and the most recent quarterly balance is more than seven million five hundred thousand dollars.
