Assign a unique number to each <br /> unit. The number can be sequential (1,2,3)or using any system you choose. <br /> This form is to be ased by all fixed Permit by Rule (PBR) units only. The Ousite Treatment Form combined with the unit <br /> specific notification supercedes DTSC Forms 8462A and 8462B. Do not use any part of DISC 1772 for Transportable Treatment <br /> Units(TTUs). TTUs must continue to use DTSC Forms 8429 and 8429A,as modified for AB 1772. <br /> The wasrestreams treated must be limited in those listed in title 22,CCR,section 67450.11,which are also fisted below. <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 m the narrative(Section 11)if your operations have seasonal variations. <br /> I.
