<br />Primary waste generators:
<br />For LLNL
<br />7.1 Organic Liauid from Oil/Water Separator for Fleet Maintenance
<br />In the 2007 SB 14 Plan, this waste stream was classified as CWC 134 and is addressed in
<br />Section 3.4. The 12,750 Ibs of waste from this process (shown in the table, above) was
<br />reclassified as CWC 223 in 2010.
<br />7.2 Site 300 Oil Contaminated Water
<br />This waste stream is from oil contaminated water and rags. In 2010, 5,719 lbs were
<br />generated at Site 300, compared to 18,376 IN in 2006. In 2006, oil -contaminated water
<br />and rags collected from various locations at Site 300, including maintenance of the Flash
<br />X -Ray tank process, constituted one of LLNL's major waste streams. The aqueous
<br />portion, which comprised most of this waste stream, has been significantly reduced
<br />through a number of methods. Different process and constituent waste streams are now
<br />segregated and handled separately, facilitating identification of some nonhazardous waste
<br />streams which were then re -characterized. Another nonhazardous waste stream,
<br />generated from photo processing developer has been almost entirely eliminated due to
<br />use of an evaporation unit. In addition, Site 300 plans to move from chemical -based
<br />photo processing to digital photography within the next four to five years.
<br />The quantity of this waste stream is below the SB 14 reporting requirements.
<br />The remaining 9,197 lbs of waste included in the 2007 SB 14 report total for CWC 223
<br />was from small, unrelated processes and is not addressed in the 2011 SB 14 Plan.
<br />Note that the 2010 CWC 223 waste volume at Site 300 is below the SB 14 reporting
<br />threshold.

<br />For SLAC
<br />In 2010, 23,738 pounds of CWC 223 waste was generated at SLAC. A breakdown by
<br />waste descriptions used in the SLAC hazardous waste tracking system is provided in the
<br />table below and compared with 2006 quantities.

<br />7.3 Vehicle and Equipment Steam Cleaning Operations and Collection
<br />Sumn Generatine Oily Sludge
<br />For this waste stream, 13,670 pounds in 2010. In 2006, only 611 pounds of this waste
<br />was generated, since the operations were the result of small cleaning operations that were
<br />pumped on a periodic basis. In 2010, the large quantity of oily sludge generated included
<br />approximately 600 pounds of waste from routine steam cleaning and sump cleanout
<br />operations and the balance, close to 13,000 pounds, from a massive cleaning effort
<br />resulting from extensive use of transportation and maintenance equipment. This massive
<br />cleanout was performed because of the unexpected detection of metallic lead, possibly
<br />from a combination of cleaning of lead -containing equipment (that should not have been
<br />cleaned with this system) or from extended collection and holding of sludge in the
<br />separator tank when it was originally expected to qualify as non -hazardous and not
<br />containing lead. As a preventative measure, only motor vehicles are cleaned in this area,
<br />no other equipment.
<br />7.4 Oily Solid and Solvent Solid Debris
<br />In 2010, 10,114 pounds of this waste stream were generated and in 2006, 14,321 pounds
<br />were generated indicating a trend in the right direction.
<br />This waste stream is generated in the forms of:
<br />• Replacement of old air compressor and air desiccant systems with two newer ones
<br />at Buildings 7 and 23.
<br />• Oily rags or wipes to cleanup equipment and machines that are identified above in
<br />waste stream CWC 221.
<br />• Rags used for cleaning of tools.
