(a) A generator who uses the following methods for treating RCRA or non-RCRA hazardous waste in tanks or containers, which is generated onsite, and which do not require a hazardous waste facilities permit under the federal act, shall, for those activities, be deemed to be operating pursuant to a grant of conditional authorization without obtaining a hazardous waste facilities permit or other grant of authorization and a generator is deemed to be granted conditional authorization pursuant to this section, upon compliance with the notification requirements specified in subdivision (e), if the treatment complies with the applicable requirements of this section: (1) The treatment of aqueous wastes that are hazardous solely due to the presence of inorganic constituents, except asbestos, listed in subparagraph (B) of paragraph (1) and subparagraph (A) of paragraph (2) of subdivision (a) of Section 66261.24 of Title 22 of the California Code of Regulations, and which contain not more than 1,400 ppm total of these constituents, using the following treatment technologies: (A) Phase separation, including precipitation, by filtration, centrifugation, or gravity settling, including the use of demulsifiers and flocculants in those processes. (B) Ion exchange, including metallic replacement. (C) Reverse osmosis. (D) Adsorption. (E) pH adjustment of aqueous waste with a pH of between 2.0 and 12.5. (F) Electrowinning of solutions, if those solutions do not contain hydrochloric acid. (G) Reduction of solutions that are hazardous solely due to the presence of hexavalent chromium, to trivalent chromium with sodium bisulfite, sodium metabisulfite, sodium thiosulfite, ferrous chloride, ferrous sulfate, ferrous sulfide, or sulfur dioxide, provided that the solution contains less than 750 ppm of hexavalent chromium. (2) Treatment of aqueous wastes that are hazardous solely due to the presence of organic constituents listed in subparagraph (B) of paragraph (1), or subparagraph (B) of paragraph (2), of subdivision (a) of Section 66261.24 of Title 22 of the California Code of Regulations and that contain not more than 750 ppm total of those constituents, using either of the following treatment technologies: (A) Phase separation by filtration, centrifugation, or gravity settling, but excluding supercritical fluid extraction. (B) Adsorption. (3) Treatment of wastes that are sludges resulting from wastewater treatment, solid metal objects, and metal workings that contain or are contaminated with, and are hazardous solely due to the presence of, constituents, except asbestos, listed in subparagraph (B) of paragraph (1) of, and subparagraph (A) of paragraph (2) of, subdivision (a) of Section 66261.24 of Title 22 of the California Code of Regulations, or treatment of wastes that are dusts that contain, or are contaminated with, and are hazardous solely due to the presence of, not more than 750 ppm total of those constituents, except asbestos, listed in subparagraph (B) of paragraph (1) of, and subparagraph (A) of paragraph (2) of, subdivision (a) of Section 66261.24 of Title 22 of the California Code of Regulations, using any of the following treatment technologies: (A) Physical processes that constitute treatment only because they change the physical properties of the waste, such as filtration, centrifugation, gravity settling, grinding, shredding, crushing, or compacting. (B) Drying to remove water. (C) Separation based on differences in physical properties, such as size, magnetism, or density. (4) Treatment of alum, gypsum, lime, sulfur, or phosphate sludges, using either of the following treatment technologies: (A) Drying to remove water. (B) Phase separation by filtration, centrifugation, or gravity settling. (5) Treatment of wastes listed in Section 66261.120 of Title 22 of the California Code of Regulations, which meet the criteria and requirements for special waste classification in Section 66261.122 of Title 22 of the California Code of Regulations,
