Aqueous wastes with total organic carbon less than Igo percent as measured by EPA Method 9060 and less than png <br /> percent total volatile organic compounds as measured by EPA Method 8240 may be treated by the following <br /> technologies: <br /> ❑ a. Phase separation by filtration, centrifugation or gravity settling, but excluding super critical fluid extraction. <br /> ❑ b. Adsorption. <br /> ❑ C. Distillation. <br /> ❑ d. Biological processes conducted in tanks or containers and utilizing naturally occurring microorganisms. <br /> ❑ e. Photodegradation using ultraviolet light,with or without the addition of hydrogen peroxide or ozone, provided the <br /> treatment is conducted in an enclosed system. <br /> ❑ f. Air stripping or steam stripping. <br /> 4. Sludges, dusts, solid metal objects and metal workings which contain or are contaminated with metals listed in Title <br /> 22, CCR, Section 66261.24 (a)(2) and/or fluoride salts may be treated by the following technologies: <br /> ❑ a. Chemical stabilization using silicates and/or cementitious types of reactions. <br /> ❑ b. Physical processes which change only the physical properties of the waste such as grutding, shredding, crushing, <br /> or compacting. <br /> ❑ C. Drying to remove water. <br /> ❑ d. Separation based on differences in physical properties such as sire, magnetism or density. <br /> DTSC 1772A (7,/94) Page 5 <br />
