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