LLNL plans to continue the existing source reduction measures and best management practices such as limiting the number of wax layers that can be applied prior to stripping, performing floor care only when needed and continuing to evaluate alternative floor cleaning products that could lead to the reduction or elimination of hazardous waste. Note that the 2010 waste volume from this process is included in the CWC 132 table in Section 2 and is not in the CWC 134 total. 3.4 Or¢anic Liquid from Oil/Water Separator for Fleet Maintenance The liquid from Oil/Water Separator for Fleet Maintenance was reclassified from CWC 134 to CWC 223 to more accurately describe this waste. The 12,450 IN of this waste generated in 2006, was essentially the same as the 12,750 lbs generated in 2010. Use of the oil/water separator continues to function well as a source reduction measure, by separating out the oils and allowing the water to meet sewer discharge release requirements. Otherwise, the waste stream generated from steam cleaning and car wash operations would be significantly higher. Note that the 2010 waste volume from this process is included in the CWC 223 table in Section 7 and is not in the CWC 134 total. 3.5 Ground Water Treatment Unit Scale Removal Onerations In 2010, 1,566 lbs (identified as CWC 134) of this waste stream were generated at Site 300, compared to 836 Lbs (identified as CWC 132) in 2006. Although included in the 2007 SB 14 plan, the waste produced from ground water treatment unit scale removal operations was significantly below SB14 reporting requirements. This waste stream continues to be below SB14 reporting requirements. Environmental restoration operations continue to use Belsperse 161, a commercial product used to reduce scale formation, thus reducing the need for scale removal. Base conditions vary from year to year as facilities are operational or down for maintenance/repair, causing some variability in waste generation. Belsperse has been September 1, 2011 SB 14 Report 1 1 September 1, 2011 SB 14 Report used since 1998 in an on-going effort to decrease waste while improving performance of In an effort to improve both pollution prevention and worker health and safety, the team equipment. that carries out floor maintenance and floor stripping operations routinely tries alternative stripping products, such as products that do not contain zinc or are Green Seal certified. Note that the 2010 waste volume from this process is below the SB 14 reporting threshold and therefore is not included in the 2010 CWC 132 total in Section 2. Periodically, the custodial organization evaluates new products, looking for alternatives that increase worker health and safety and reduce impact to the environment. Three years ago, alternative floor care products were evaluated but none were available that had the required level of performance. Another product evaluation cycle is currently underway with an emphasis on Green Seal certified floor care products.
