The manufactured home installation training account is created in the state treasury. All receipts collected under this chapter and RCW
46.17.150 and any legislative appropriations for manufactured home installation training shall be deposited into the account. Moneys in the account may only be spent after appropriation. Expenditures from the account may only be used for the purposes of this chapter. Unexpended and unencumbered moneys that remain in the account at the end of the fiscal year do not revert to the state general fund but remain in the account, separately accounted for, as a contingency reserve.
