° 1 .6 Submittal Reminders <br /> U <br /> .a <br /> If you are required to prepare SB 14 documents, did you remember to: <br /> O <br /> .y • Prepare a Summary Progress Report as detailed in Chapter 7? <br /> • Submit your Summary Progress Report to DTSC by September 1, 2011? <br /> You are not in compliance with SB 14 unless you prepare a Summary Progress Report, and <br /> G� <br /> submit it to DTSC. <br /> CLM <br /> s A Source Reduction Success - <br /> U <br /> Children's Hospital Los Angeles <br /> Children's Hospital Los Angeles (CHLA) has been operating since April i, i go i and is a 318-bed <br /> licensed acute care pediatric hospital. The facility supports one of the largest educational programs <br /> of any pediatric institution in the country. The CHLA operates schools of Physical Therapy, Medical <br /> Technology,and X Ray Technology. Because of the research facilities on campus,CHLA has larger <br /> and more diversified hazardous waste streams than other area hospitals. <br /> Children's Hospital Los Angeles continues to implement innovative source reduction measures for <br /> all of their waste streams. In general,chemical purchases have steadily declined in the past five <br /> years while research and patient loads have increased. The following are a few examples of source <br /> reduction measures implemented at their hospital. <br /> • Analysis and evaluation was done to assess how oils, lab chemicals,and solvents entered <br /> the industrial wastewater clarifier.Analysis showed chemical residues from the labware <br /> cleaning process entering the wastewater system. All excess waste in the labware was <br /> put through the cleaning systems with disregard to chemicals ending up in the clarifier. <br /> The clarifier had to be pumped and cleaned monthly with hot water and bleach to reduce <br /> hydrocarbon buildup. In fiscal year 1994-95,a program was initiated to train personnel <br /> in the maintenance of the cleaning system, use of the proper receptacles for the collec <br /> tion and disposal of chemical wastes,and use of the autoclave for cleaning and steriliza <br /> tion of labware. <br /> In midyear 1995, hydrocarbon-reducing enzymes were introduced into the clarifier <br /> system to reduce hydrocarbons and alleviate the need to pump and clean the clarifier <br /> monthly. No capital outlay was needed, pumping costs were reduced by$1950 per <br /> month,and contaminated wastewater entering the POTW was reduced by 46,541 <br /> pounds per year. <br /> • All laboratory euthanasia now uses carbon dioxide instead of ethyl ether. This input <br /> substitution has improved worker safety and reduced the reporting of extremely hazard <br /> ous substances. In addition, there is a substantial cost difference between chemicals. <br /> • Mercury thermometers,blood pressure cuffs,and related instruments/devices were <br /> replaced with non-mercury thermometers,and electronic/chemical piezometric devices. <br /> Replacement of mercury units with new electronic devices took place over a long period <br /> to ensure product manufacturers could provide equipment that was suitable for use in <br /> the pediatric setting. Electronic devices for blood pressure and thermometer reading are <br /> comparable in cost to instruments containing mercury because they do not have hig h disposal <br /> costs.In addition,the electronic devices do not pose a hazard to patients and workers. <br /> 16 <br />
