10. CWC 352: Other Organic Solids Site 2006 Quantity (lb) 2010 quantity (lb) LLNL 22,663 12,840 LBNL 7,203 4,775 SNUCA 2,027 1,037 Primary waste generators: For LLNL 10.1 LLNL CWC 352 Wastes LLNL included CWC 352 wastes in the 2007 SB 14 plan, although none of the separate processes generated more than 2 percent of the total LLNL waste stream and therefore were under SB14 reporting threshold. The total of all CWC 352 wastes generated has dropped from 22,663 lbs in 2006 to 12,840 lbs in 2010. This waste stream is comprised of a number of small, unrelated processes and continues to not be a major waste stream category for LLNL wastes. Note that the 2010 waste volume is below the SB14 reporting threshold and so this waste stream is not carred forward into the 2011 SB14 Plan. For LBNL 10.2 Pressure Treated Lumber A significant portion of the waste stream is pressure treated lumber. This material is used in a variety of wood structures at the LBL. The waste stream also consists of kimwipes, paper towels, gloves, pipette tips, and plastics contaminated with organic materials. In 2006, this waste was primarily pressure treated lumber. In the past four years, less of this material was purchased in favor of engineered materials. For SNL 10.3 Solvent Debris Solvent debris is generated by different operations around the site. In 2006 the largest generators of solvent debris wasthe Paint Shop. Other major generators of solvent debris were the Biosystems Research Department and Materials Chemistry Department. The remaining solvent debris was small volumes generated at various laboratories throughout the site. In April 2009 the SNUCA site management decided to close the Paint Shop, that eliminated most of solvent contaminated wipes. The closure of the Paint Shop has resulted in the reduction of solvent debris generation in 2010 at SNUCA.11. CWC 551: Laboratory Waste Chemicals Site 12006 Quantity (lb) 12010 quantity (lb) SNUCA 112,357 J 8,977 LBNL 13,151 15,556 Primary waste generators: For SNUCA 11.1 Laboratory Waste Chemicals Laboratory waste chemicals are generated from different operations around the site. In 2006 some of the largest generators were the Maintenance -Engineering, Materials Chemistry Department, Biosystems Research Department, Material Physics Department, and the Engine Combustion Laboratory. Also in 2006 SNUCA conducted a site -wide cleanout to reduce site -wide chemicals by 5%. The cleanout in 2006 generated 3100 lbs of laboratory waste chemicals. In April 2009 the SNUCA site management decided to close the Paint Shop. The closure of the Paint Shop has resulted in the reduction of the generation of laboratory waste chemicals at SNUCA. In addition SNUCA did not conduct a major site wide cleanout in CY10. Note, several organizations throughout the site conducted small cleanouts however these did not generate a large volume of laboratory waste chemicals. 11.2 SNUCA Firine Ranee SNUCA has a firing range used for training purposes. After personnel have completed training activities, they washed their hands (with soap and water) to remove any residues from handling ammunition and/or firing handguns. Wash water was containerized and transported off-site for disposal as a hazardous waste. Through September 2006, SNUCA determined (using process knowledge) that this waste stream is characteristically hazardous for lead. In September 2006 SNUCA completed its evaluation to reduce the lead contamination in the wash water by having the Protective Force wipe their hands with an alcohol -free wipe prior to washing their hands. Analytical analyses confirmed the concentration of lead was below the hazardous waste limit and therefore, not deemed a California hazardous waste. It was determined that the wastewater can be released into the sanitary sewer and will not exceed the local POTW discharge limits. This waste stream is no longer generated at SNUCA.
