-5- adsorption, chemical oxidation, filtration, and biological treatment. ® 14. Due to the make-up of Minnesota's waste stream the types of chemical treat- ment facilities most likely to be developed in the state include treatment ficil- ities for solvents, oils, and aqueous wastes. 15. Incineration involves high temperatureconversion-efnhazardousvaste-toakYr products such as carbon dioxide and 'steaNr and'•ash residues. At an incineration facility, organic wastes are fed into a chamber where temperatures are maintained above 700 degrees centrigrade. Air is typically added to facilitate combustion. Exhaust gases are passed through scrubbers for cleaning and removal of harmful materials. 16. Hazardous waste incinerators are required to achieve a 99.99% destruction and removal efficiency for each principal organic hazardous constituent designated in its permit for each waste feed. 40 C.F.R. Fart 264 Subpart 0. 17. Environmental Protection Agency regulations for processing facilities require a primary containment device For all facilities which is designed to prevent leak- age and overflow for as long as the wastes will remain in the facility. An inspection program is also required to monitor any deterioration in the primary containment system so that repairs or replacement can be made before any releases occur; or failing that, to detect leaks before they become major or result in significant con- tamination. In addition, where the primary containment device is easily damaged and/or where inspection is difficult, a secondary containment device is required. See 46 Fed. Reg. 2808 (1980); 40 C.F.R. Part 264. 18. At closure, all hazardous waste and hazardous waste residues must be removed from the facility. Remaining containers, tanks, liners, bases, and soil containing 1 or contaminated with hazardous waste or hazardous waste residues must be decontamin-• ated or removed. See 40 C.F.R.§§ 264.178, 264,197, 264.228, 264.258 and 264.351.
