<br /> CONDITIONALLY AUTHORIZED
<br /> UNIT SPECIFIC NOTIFICATION
<br /> (pursuant to Health and Safety Code Section 25200.3)
<br /> UNIT NAME Chromium treatment system UNIT ID NUMBER 4-0
<br /> NUMBER OF TREATMENT DEVICES: I_ Tank(s) Container(s)
<br /> Each unit must be clearly identified and labeled on the plot plan attached to Form 1772. Assign your own unique number to each
<br /> unit. The number can be sequential (1, 2, 3) or you may use any system you choose.
<br /> Enter the estimated monthly total volume of hazardous waste treated by this unit. This should be the maximum or highest amount
<br /> treated in any month. Indicate in the narrative (Section 11) if your operations have seasonal variations.
<br /> I. WASTESTREAbIS AND TREATMENT PROCESSES:
<br /> Estimated Monthly Total Volume Treated: pounds and/or 3000 gallons
<br /> The following are the eligible wastestreams and treatment processes. Please check all applicable boxes.
<br /> 1. Aqueous wastes hazardous solely due to inorganics constituents, except asbestos, listed in title 22, CCR, section
<br /> 66261.24(a)(1)(3) or(a)(2)(A) and which contain less than 1,400 ppm total of these constituents. (There is no volume limit
<br /> for this wastestream.) Treatment is using:
<br /> ❑ a. Phase separation, including precipitation, by filtration, centrifugation, or gravity settling, including the use of
<br /> demulsifiers and flocculants.
<br /> ❑ b. Ion exchange, including metallic replacement,
<br /> ❑ C. Reverse osmosis
<br /> ❑ d. Adsorption
<br /> ❑ e. pH adjustment of aqueous waste with a pH of between 2.0 and 12.5
<br /> ❑ f. Electrowinning of solutions, unless those solutions contain hydrochloric acid
<br /> ❑ g. Reduction of solutions hazardous solely due to hexavalent chromium, to trivalent chromium with sodium bisulfite,
<br /> sodium metabisulfite, sodium thiosulfate, ferrous chloride, ferrous sulfate, ferrous sulfide, or sulfur dioxide. The
<br /> solution contains less than 750 ppm of hexavalent chromium.
<br /> 2. Aqueous wastes hazardous solely due to organic constituents listed in title 22, CCR, section 66261.24(a)(1)(B)or(2)(B)and
<br /> which contain less than 750 ppm total of these constituents. (There is no volume limit for this wastestream.) Treatment is
<br /> using:
<br /> ❑ a. Phase separation by filtration, centrifugation, or gravity settling, but excluding super critical fluid extraction.
<br /> ❑ b. Adsorption
<br /> 3. Sludges resulting from wastewater treatment, dusts, solid metal objects, and metal workings which are hazardous solely due
<br /> to the presence of constituents, except asbestos, listed in title 22, CCR, section 66261.24(a)(1)(B) or (a)(2)(A) and which,
<br /> for dusts only,contain less than 750 ppm total of these constituents. The monthly volume treated in this unit does not exceed
<br /> 5,000 gallons or 45,000 pounds. Treatment is using:
<br /> a. Physical processes which constitute treatment only because they change the physical properties of the waste, such
<br /> as filtration, centrifugation, gravity settling, grinding, shredding, crushing, or compacting.
<br /> ❑ b. Drying to remove water.
<br /> ❑ C. Separation based on differences in physical properties, such as size, magnetism, or density.
