UCSD Literature Building Page 1 PCB Sampling Report April 2009
April 6, 2009 Ms. Sarah Meyer UCSD, Environment, Health, and Safety Department 9500 Gilman Drive La Jolla, California 92093-0990 Dear Ms. Meyer: This letter documents the findings, recommendations, and conclusions from the PCB testing conducted by Rick Shockley, field-level industrial hygienist. The testing was supervised by Karen Shockley, Certified Industrial Hygienist (CIH #6766). Hydraulic fluid samples from the elevator equipment and surface wipe samples from the floor were collected on the first floor of the Literature Building (#627) on the UCSD La Jolla Campus in La Jolla, California. The purposes of the testing were to determine if polychlorinated biphenyls (PCBs) were present in the hydraulic fluid in the two elevator control units in the first floor elevator room (#121) and to determine whether PCBs are contaminating the floor at several areas throughout the first floor. In the course of completing this sampling, Aurora met with Steve Benedict and Sarah Meyer, UCSD Environment, Health and Safety Department; Nancy Ho-Wu and Nancy Daly, UCSD Literature Department; and Philip Oliveri, UCSD Facilities Management. PCBs were not detected in any of the samples.
Use of This Report
This report is intended to provide an understanding of the potential hazards that the areas evaluated in this report may pose to human health due to PCB contamination. This report is based primarily upon data and information obtained during a single site visit by Aurora Industrial Hygiene (Aurora) to the property identified herein on March 10, 2009 and is based solely upon the condition of the facility on the dates of such assessment. This scope of sampling was limited to PCB fluid and surface sampling in selected areas on the first floor of the building. Aurora has performed this work, made the findings, and proposed the recommendations described in this report in accordance with generally accepted industrial hygiene and environmental science practices in effect in the Southern California area at the time the work was performed. This warranty stands in lieu of all other warranties, expressed or

implied. While this report can be used as a guide, it must be understood that it is neither a rejection nor an endorsement of the facility. It must also be understood that changing circumstances in the environment can alter radically the conclusions and information contained in this report.
PCB Sample Collection and Analysis Fluid Samples
UCSD Facilities Management personnel collected two (2) fluid samples, one from each of the two elevator control units in room 121. Aurora personnel witnessed the sample collection and then received the samples from UCSD personnel. Both samples were analyzed for PCB content by EPA method 8082, gas chromatography, by American Scientific Laboratories. Wipe Samples
Rick Shockley collected five (5) surface wipe samples from the floor. Each wipe samples covered an area of one square foot. One sample was collected from the floor between the two elevator control units in room 121; one sample was collected from near the east elevator control unit where a spill occurred several years ago; one sample was collected from the lobby area in front of the elevators on the first floor; and two samples were collected from the hallway floor, in front of rooms 124 and 137. All of the samples were analyzed for PCB content by EPA method 8082, gas chromatography, by American Scientific Laboratories. All of the PCB samples were assigned unique sample identification numbers, placed in sealed containers, labeled, and delivered by Federal Express to American Scientific Laboratories, LLC in located at 2520 N. San Fernando Road, Los Angeles, California 90065. American Scientific is accredited by the State of California Department of Public Health Environmental Lab Accreditation Program. Appendix One contains a diagram depicting sample locations. Appendix Two contains photographs of the sample locations.

Discussion
Polychlorinated Biphenyls (PCBs) are colorless to light yellow, viscous liquids (above 50oF) that can be detected by their mild hydrocarbon odor. PCBs are non-flammable but are strong oxidants. The routes of exposure for PCBs are inhalation, ingestion, and skin and eye contact leading to absorption. PCBs exposure is known to target the skin, eyes and liver. The primary effect of exposure to PCBs is a type of dermatitis known as chloracne associated with skin contact. The current permissible exposure limits (PELs) for PCBs are 0.5 mg/m3 and 1.0 mg/m3 for 54% chlorine and 42% chlorine substitution, respectively. These compounds are suspected carcinogens based on animal studies. PCBs have been used as coolants and lubricants in transformers, capacitors, and other electrical equipment because they do not burn easily and are good insulators. The manufacture of PCBs was stopped in the U.S. in 1977 because of evidence they build up in the environment and can cause harmful health effects. Products made before 1977 that may contain PCBs include old fluorescent lighting fixtures and electrical devices containing PCB capacitors, and old microscope and hydraulic oils. PCBs were not detected in the hydraulic fluid or surface wipe samples.

Limitations
The data and observations collected during the course of this assessment have been gathered to provide the Client with information pertaining to the subject property identified in this report. Although Aurora believes that the findings and conclusions provided in this report are reasonable, the assessment is limited to the conditions observed and to the information available at the time of the work. Due to the nature of the work, there is a possibility that there may exist conditions which could not be identified within the scope of the assessment or which were not apparent at the time of our site work. The assessment is also limited to information available from the client at the time it was conducted. It is also possible that the testing methods employed at the time of the report may later be superceded by other methods. Aurora does not accept responsibility for changes in the state of the art. We hope that this information is helpful. Please feel free to contact us at (619) 276-5901 if you have any questions. Sincerely,
