Yet there are residues from both of thesc systcms. The water treatmenl system cleans about five mdlion gallons of water each day and removes 95 percent of the wastes from the water. In the process, though, it produces about 14,00(I tons of sludge a year. 94 Percent Reduction The multi-million dollar Chemolite incinerator one of the most advanced in the world - disposes of about 14,000 tons of chemical wastes a year. It reduces that volume by about 94- percent to 2,500 tons of ash. This is the res/due~ the left-over material from the Chemelite incinerator. So, in the process of cleaning man y millions of gallons of water and disposing of 14,000 tons of chemicals, the Company's pollution contro! facilities are left with some 16,000 tons of waste residue. And, the disposal ~f this resi~ ae has put 3M at the center of a dilemma. Until last year, the Company hauled these residues to the nearby Pine Bend landfill where they were disposed of" along with municipal wastes from !ocal communities. But in 1978, the Minnesota Pollution Control Agency (MPCA) staff" concluded that there was a potential hazard in mixing the Chemolite wastes with the municipal refuse.
