There is hereby created in the state treasury a special nonreverting fund to be known as the Marine Habitat and Waterways Improvement Fund, hereafter referred to as “the Fund.” The Fund shall be established on the books of the Comptroller. In addition to the receipt of moneys as may be specifically provided by law, the Commissioner is authorized to accept gifts and grants for the Fund, as well as proceeds that may be received from time to time on the sale of state-owned marine lands. Interest earned on moneys in the Fund shall remain in the Fund and be credited to it. Any moneys remaining in the Fund, including interest thereon, at the end of each fiscal year shall not revert to the general fund but shall remain in the Fund. Moneys in the Fund shall be used solely for the purposes of improving marine habitat and waterways, including the removal of obstructions or hazardous property from state waters as authorized in §§ 15.2-909 and 28.2-1210. Expenditures and disbursements from the Fund shall be made by the State Treasurer on warrants issued by the Comptroller upon written request signed by the Commissioner.
