3. MAJOR WASTE STREAMS ................................................................................................................................................................................. 3.1 . APPLICABILITY SB 14 requires that all hazardous wastes be identified and categorized for purposes of applicability. Only "major"waste streams that constitute 5%or more by weight from the facility,which are routinely generated or otherwise not exempt are subject to SB 14 source reduction efforts. Major waste streams can fall into one of three main categories. i Category A: Hazardous wastes that are processed through an on-site waste water treatment unit prior to discharge to a publicly owned treatment works (POTW) or to receiving water under a National Pollutant Discharge Elimination System (NPDES)permit. > Category B:All other hazardous wastes,including waste shipped off site for treatment,recycling or disposal, manifested waste,and waste that is treated or disposed on site. 1 i Category C:Wastes that are classified as extremely hazardous wastes. SB 14 source reduction applies to major waste streams within each of the above waste categories. Note that for similar process waste streams sharing the same California Waste Code (CWC),the wastes may be subtotaled into a single major waste stream when making the 5%major waste calculation.z Accordingly,when a generator is identifying its major waste streams,only those individual waste streams having the same CWC and being from similar processes or operations can be grouped and subtotaled as a single major waste stream having that CWC. However,individual waste streams sharing the same CWC but not originating from similar processes or operations cannot be grouped and subtotaled as a single major waste stream having that CWC. 3.2. EXEMPTED WASTES DTSC exempts a waste stream from the requirements of SB 14 if the waste has no source reduction opportunities,or is not routinely generated. In addition,a generator does not include an exempted waste stream when calculating the total weight of hazardous waste generated at a site to determine SB 14 applicability. The following waste streams are specifically exempted by 22 CCR Section 67100.2,and should be excluded from total facility hazardous waste for SB 14 purposes: > Motor vehicle fluids and motor vehicle filters ;0- Lead acid batteries ;P Household hazardous wastes,wastes from household collection events,and wastes separated at community landfills > Waste pesticides and pesticide containers collected by county agricultural commissioners > Spent munitions and ordinance > Decommissioned utility poles ;0- Oil generated from decommissioned refrigeration units 0- Mercury relays and low-level radioactive tubes generated from removal of telephone equipment. ;P Lighting wastes including ballasts and fluorescent tubes > Waste from site cleanup and mitigation activities,including remedial investigations In 1998 and earlier editions of SB guidance manual,the term aqueous waste was used to describe hazardous wastes that fall under Category A;and nonaqueous waste was used to describe wastes that fall under Category B.z 22 CCR §67100.5 (h) DTE Stockton, LLC I SB 14 Source Reduction Evaluation and Review Trinity Consultants 3-1
