There is hereby established in the state treasury a subfund of the water and environment fund to be designated as the South Dakota well rehabilitation and plugging subfund. This subfund shall consist of all moneys, including legislative appropriations; interest on the well rehabilitation and plugging subfund; and, notwithstanding the provisions of § 34A-12-15, all money collected by the department in the enforcement of the provisions of Title 46, chapter 34A-2A, or in any other action, proceeding or settlement based upon violation of the state's water laws, excluding criminal proceedings for criminal fines. Expenditures from this subfund shall be appropriated through the normal budget process. Unexpended funds and interest shall remain in the subfund until appropriated by the Legislature.
