No person shall dump or deposit or permit the dumping or depositing of any solid waste on the surface of the ground or into a body or stream of water at any place other than a sanitary disposal project approved by the Director of the State Department of Natural Resources, unless a special permit to dump or deposit solid waste on land owned or leased by such person has been obtained from the Director of the State Department of Natural Resources. However, this section does not prohibit the use of rubble at places other than a sanitary disposal project. As used in this section, "rubble" means dirt, stone, brick, or similar inorganic materials used for beneficial fill, landscaping, excavation, or grading at places other than a sanitary disposal project. "Rubble" includes asphalt waste only as long as it is not used in contact with water in a floodplain. For purposes of this section, "rubble" does not mean gypsum or gypsum wallboard, coal combustion residue, foundry sand, or industrial process wastes unless those wastes are approved by the State Department of Natural Resources.
