An investigation to determine the source of contamination revealed that both airborne particulates and PCBs had migrated into the field equipment room over an extended period of time. Further investigation of the area showed a pattern of coincidental particulate accumulation and PCBs that is greatest in the first floor parking garage and extends into the lower parking areas in decreasing amounts. Air monitoring confirmed the coincidence of airborne particulates and PCBs. Additional wipe samples and observation could find no other likely sources, such as spills. While airborne particulates were found to be associated with the PCBs, a definitive source of contamination remains unknown. Efforts to clean the equipment room, implement dust control measures and remove the gauze pads and other equipment from this area are recommended. Background Polychlorinated Biphenyls (PCBs) are a group of organic chemicals that persist in the environment and are known to cause serious health effects. Generally, PCBs are made up of a biphenyl molecule containing anywhere from 1 tolO chlorine atoms. An individual PCB molecule is classified as a "Congener" and is given a specific name. Formulated mixtures of PCBs are known by the trade name "Aroclor" and are classified by a number (e.g., Aroclor 1254). Because PCBs are highly stable, non-flammable and insulate well, they were manufactured and used in a variety of commercial and industrial applications for 50 years until their ban in the late 1970's. The EPA Region 10 field equipment room is located on the first level of the Park Place Building parking garage. The room is a locked storage area comprised of shelves, stainless countertops, lockers, refrigeration and a large sink (Figures 1-2, page 6). For many years, the room has served as storage for field equipment, as a personal changing area, and as space for conducting respirator fit tests. Entry is controlled through electronic key cards of which 100 employees have access. Air ventilation to the room is provided through a passive air vent connected to the parking garage along with a second exhaust vent that is shared with the dive team room. Ventilation to the parking garage is provided by vents that supply outside air to each parking level with the main air intake located on the building's east side, second floor area. During a recent PCB inspection, gauze pads from the field equipment room were used for the collection of wipe samples. Routine quality control analysis of the pads showed them to be contaminated with PCBs as Aroclor 1254. Follow-up analysis indicated that the entire lot of pads contained PCBs in the range of 5-10 micrograms per pad. The cardboard storage box for the pads was also tested and showed contamination. Replacement pads from the Manchester Lab equipment warehouse were tested and PCBs were not detected. An investigation to determine possible sources of PCB contamination in the sampling pads and the field equipment room was initiated. Investigation The Region 10 TSCA-PCB Site-Specific Inspection Plan (PSSIP), originally designed for PCB inspections, was employed for this study. Surface wipe and air filter samples were collected in the field equipment room and adjoining parking garage. Samples were submitted under custody to the Region 10 Manchester Laboratory for analysis of PCBs. Sample collection was initiated on 1 ------- January 22, 2008 and occurred in three phases. Phase 1 focused primarily on the collection of surface wipes in the equipment room. Phase 2 expanded the sampling effort into the parking garage. Phase 3 saw the addition of monitoring for airborne particulates in both the equipment room and parking garage. For field quality control, blank gauze pads or air filters were submitted to the lab during each respective phase. The final QA reviewed data package was completed by the lab on February 22, 2008. All positive PCB results reported by the lab were identified as Aroclor 1254. The summary of sampling activities follows. Phase 1 of the investigation centered on the collection of wipe samples in areas where concentrated sources of PCBs were likely to occur inside the equipment room. These areas included the floor, lighting and shelf where the contaminated pads were stored. Other areas or items such as the lockers, piping, refrigerator and custody seals were sampled due to concerns over direct exposure, proximity to old light ballasts or the distribution of items to EPA contractors. Based on preliminary lab results, follow-up sampling was conducted on the locker tops (versus the locker doors), the passive air vent leading into the equipment room, and an air respirator mask. The air vent data showed higher PCB concentrations over the entire vent area on the outside the equipment room versus the inside. This trend in the data was also accompanied by a similar trend in the observed accumulation of dust on the vent covers. Phase 2 targeted locations of dust accumulation in the parking garage. Specifically, sprinkler pipes located on the Northeast corner of floors P1-P3 of the parking garage in addition to the height-limit bar located near the outside entrance and leading down into the garage. Following the previous round of sampling, it was observed that dust accumulation on these pipes appeared relatively undisturbed and tended to decrease in the lower floors. Here wipe samples were collected from the tops of the pipes at a distance between the sprinklers (approximately 3 meters). The objective was to confirm if measurable PCBs were present and followed the same trend as the dust accumulation. Separate from the sprinkler pipes, the height limit bar was sampled to determine if both visible dust and PCBs could be detected on a deposition surface nearer the garage entrance where outside air was more readily available. The Phase 3 sample collection consisted of air monitoring for particulates in the 1st floor parking garage and equipment room. This effort was initiated due to the observation of surface dust and PCB content. Sampling occurred during both traffic hours and when the areas were undisturbed (i.e. overnight). The monitoring equipment consisted of mini-volumetric samplers equipped with micro-fiber quartz filters for collecting airborne particulates (Figures 16-17, page 11). Because these filters are designed to trap small particulates, data from this sampling round was to determine if the coincidence of airborne particulates and PCBs could be confirmed. Results and Discussion Analytical results for the surface wipe and air filter samples are provided below. Data tabulation and assessment have been segregated in accordance with each phase of the investigation. From the onset of the investigation, source attribution based on observations of the area proved difficult. Throughout the entire investigation, the greatest weight of evidence appeared to be the consistent identification of PCBs as Aroclor 1254. As the investigation progressed toward comparing aggregate dust accumulation and PCB content, the physical evidence supporting this trend relied upon photographic comparisons of the wipe sample pads and PCB results. The photographic comparisons are provided in the attached figures (Appendix A). ------- All samples were analyzed for PCB Aroclors at the EPA Region 10 Manchester Laboratory using EPA method 8082. For these data, quality control indicators, including sample blanks, were within the method criteria. No data were rejected for non-compliant quality control (see QA Review, Appendix B). All results were reported in micrograms (jig) of Aroclors. PCBs were detected in several samples at concentrations below the lowest instrument linear calibration standard. These data were qualified as "estimates" by the lab and are viewed as "detected" but not "quantified". Field Equipment Room Samples - Phase 1 PCB results for wipe samples collected in the field equipment room were in the range of non-detect to 16 jig. For all areas, surfaces were over sampled (greater than the standard 10 square centimeters) to ensure confirmation on the presence or absence of PCBs (see Table 1). Results for the custody seal, respirator mask and shelf (where the contaminated gauze pads were stored) were not detected. For these samples, it was also noted that the custody seals were purchased within the past year, the respirator masks are routinely cleaned and the shelf location had also been cleaned within the past year. PCBs in samples taken from the sides of the light fixture were split between detected and not detected. Other detected (but not quantified) values represented areas on the refrigerator top, locker composite and locker doors. When the locker tops were sampled separately (Figures 4-5, page 7), the PCB content was quantified. The top of the pipe (near ceiling) and floor were the other areas where PCBs were quantified. In addition to the PCB data, the equipment room appeared free of any containers that may contain solvents or lubricants that may contain PCBs. Signs of a visible spill or staining on the floor, lighting, ceiling, walls or area around the storage shelf were not observed. Although the overall wipe sampling effort could not find a definitive source of contamination it was observed that the majority of detected PCBs were accompanied by visible dust on the gauze pads.

The "U" qualifier is a "non-detect" ** Area measurements were not recorded as surfaces were over-sampled (i.e., > 10cm2) or not applicable. ------- Parking Garage Samples - Phase 2 The sampling effort in the parking garage resulted in two major trends which can be seen in Table 2 below. The first of these is the greater amount of PCBs found on the air vent cover in the parking garage when compared to the opposite cover in the equipment room (Figures 7-9, page 8). Here the PCBs recovered from vent in the parking garage were approximately three times greater than those found in the equipment room. The dust on the vent louvers was also noticeably thicker in the parking garage compared to the equipment room. The second trend could be found in the comparison of samples retrieved from the tops of sprinkler pipes within the different floors of the parking garage. Sampling occurred at the northeast corner locations where a similar physical setting could be found on each floor. From the data it appears that both the amount of dust (Figures 10-12, page 9) and PCB content were lowest on the 3rd (P3) floor and highest on the 1st floor. The trend in dust accumulation between the floors was also noted by several members of the project team during a walk through of the parking garage. The final sample taken from the height limit bar near the garage entrance (Figures 13-15, page 10) also provided confirmation of the trend between dust accumulation and PCBs. Due to the difference in physical setting for this location however, a direct comparison to the sprinkler pipes and vent covers was not performed. Table 2.

Particulate Air Filters - Phase 3 The results for paniculate air samples (Figures 16-17) were able to detect PCBs at 0.005 and 0.011 micrograms per cubic meter (|ig/m3). Though the results were not quantitative the detection of PCBs in these samples confirms the association between trace level PCB contamination and airborne particulates. Table 3.

Filters were comprised of Whatman high purity quartz micro-fiber. The "J" qualifier represents values that were detected below the instrument's lowest calibration standard and are estimates. Quantitative comparisons of " J" qualified data cannot be performed. ------- Conclusions and Recommendations An assessment of the data indicates a coincidence of airborne particulates and PCBs that have migrated from the parking garage into the field equipment room at trace level concentrations. The build up of parti culates in the equipment room and air vent suggest that this has been occurring over an extended period. While the consistent identification of Aroclor 1254 would suggest a single source for the PCBs, the data do not provided for definitive source attribution. A few examples of possible sources include gasoline and diesel engines, transmission fluids, transformers, light ballasts, old caulks, paints and expansion joints. In addition, the coincidence between particulates and PCBs may either be an indication that these parameters follow similar deposition patterns and are commingling in the air, or that the PCBs originated in particulate form. Additional investigation of the particulates would be needed to provide more insight. The location of the field equipment room is adjacent to the payment kiosk of the parking garage. Here automobiles, routinely idle while tenants pay in order to leave the garage. During commuting hours, a line of vehicles will often form past the equipment room. Under these circumstances, exhaust from the cars can build up near the entrance and intake vent to the equipment room for short periods of time. Auto exhaust is a suspected major contributor to particulates in the parking garage. Given the prospect that the migration of particulates and PCBs into the equipment room will continue, certain housekeeping measures and changes are recommended. These are as follows: • Clean out and install a micro-pore filter in the equipment room air vent • Install a seal on the bottom of the equipment room door • Tile/paint the floor and paint the walls, ceiling and external pipes in the equipment room • Remove clean expendables from the equipment room and store in another area • Annually clean and wipe down all internal surfaces and field equipment, boots, hats, etc. • Store small items in sealable clear plastic containers ------- Appendix A - Figures Figure 1 Equipment Room (facing entrance leading into parking garage) Figure 2 Equipment Room (rear area) Figure 3 Shelf where Gauze Pads were stored ------- Appendix A - Figures Figure 4 Equipment Room Locker Tops Figure 5 Equipment Room Locker Top Wipe Sample (11 ]ig PCBs) Figure 6 Equipment Room Locker Door Wipe Sample (0.3 pg PCBs) ------- Appendix A - Figures Figure 7 Equipment Room Vent (outside equipment room 133 pg/m PCBs) 19A Figure 8 Equipment Room Vent (inside equipment room 41 ]ig/m2 PCBs) Figure 9 Vent Cover Wipe Samples (#3-inside room, #4-outside room) ------- Appendix A - Figures Figure 10 Sprinkler Pipe Parking Level 1 (60 pg/m2 PCBs*) *Gauze Pad in this image was refolded during sampling to avoid loss of dust Figure 11 Sprinkler Pipe Parking Level 2 (26 pg/m2 PCBs) Figure 12 Sprinkler Pipe Parking Level 3 (14 pg/m2 PCBs) ------- Appendix A - Figures Figure 13 Parking Entrance Height Limit Bar N RANGE PUBLIC PARKING NO VANS OR CAMPERS Figure 14 Sampling of Height Limit Bar (some dust visible) Figure 15 Gauze Pad for Height Limit Bar (17 pg/m2 PCBs) 10 ------- Appendix A - Figures Figure 16 Mini-volumetric Sampler in Equipment Room Figure 17 Mini-volumetric Sampler in the Garage Area 11 ------- Appendix B - Mini-Volumetric Calibration Field Equipment Room Sampler Qind 7 6 5 4 Mvol = Bvol = Tact = Pact = Tstd = Pstd = time = tot vol : Parking Qind 7 6 5 4 Mvol = Bvol = Tavg = Pavg = Tstd = Pstd = time = tot vol : Qcalc-stp .0 6.78 .0 5.77 .0 4.77 .0 3.76 1.0057 -0.2575 290.25 753.8 298 760 1278 8.60 Qcalc-ltp Qtri-ltp 6.72 1 8.35 5.74 | 6 85 4.74 5.00 3.74 3.89 Mflo = Bflo = airmetrics 294.85 airmetrics 743.25 minutes Qtri-stp Man-ind Qman-ltp Qman-stp 8.40 3.18 6.69 6.73 f^.SO 2.33 5.75 5.78 5.03 1.60 4.80 4.82 3.91 1.02 3.86 3.89 5.8015 0.1731 garage garage % diff -0.80% 0.27% 1.19% 3.24% Garage Area Sampler Qcalc-stp .0 6.71 .0 5.72 .0 4.77 .0 3.76 0.9779 -0.1386 290.25 753.8 298.15 760 9.32 Qcalc-ltp Qtri-ltp 6.64 1 9.46 5.68 | 6.92 4.74 5.04 3.74 3.89 Mflo = Bflo = airmetrics 294.85 airmetrics 743.25 minutes m3 |B Qtri-stp Man-ind Qman-ltp Qman-stp 9.41 3.18 6.69 6.73 6.8^ 2.35 5.77 5.81 5.01 1.63 4.84 4.87 3.87 1.04 3.90 3.92 5.8015 0.1731 garage garage % diff 0.30% 1.58% 2.04% 4.11% 12 ------- Appendix C - Laboratory Data 13 ------- UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION 10 LABORATORY 7411 Beach Dr. East Port Orchard, Washington 98366 QUALITY ASSURANCE MEMORANDUM FOR ORGANIC CHEMICAL ANALYSES Date: February 22, 2008 To: Keven McDermott, Project Officer USEPA Region 10, Office of Environmental Assessment From: Steven Reimer, Chemist Office of Environmental Assessment, USEPA Region 10 Laboratory cc: Cathe Bell, Industrial Hygienist USEPA Region 10, Office of Management Programs Subject: Quality Assurance Review for the PCB Analysis of Samples from EPA Region 10 Room 19A Project Code: ESD-141A Account Code: 0809B10P501E50C The following is a quality assurance review of the data for PCB analysis of wipe and filter samples from EPA Region 10 Room 19A.

Preliminary Data Preliminary data were reported on the 23rd and 25th of Jan 08 for the week 04 samples and on the 1st of Feb for the week 05 samples. The results have not changed. 14. Data Qualifiers The U qualifier was attached to some results. The J qualifier was attached to five results. The definition for the data qualifiers are as follows: U - The analyte was not detected at or above the reported value. J - The analyte was detected but the reported value is an estimate. The usefulness of qualified data should be treated according to the severity of the qualifier in light of the project's data quality objectives. Should questions arise regarding the data, contact Steven Reimer at the Region 10 Laboratory, phone number (360) 871-8718. 15. Definitions Accuracy - the degree of conformity of a measured or calculated quantity to its actual value. Laboratory Control Sample (LCS) - a clean matrix spiked with known quantities of analytes. The LCS is processed with samples through every step of preparation and analysis. Measuring percent recovery of each analyte in the LCS provides a measurement of accuracy for the analyte in the project samples. A laboratory control sample is prepared and analyzed at a frequency no less than one for every 20 project samples. Matrix Spike/Matrix Spike Duplicate (MS/MSD) - Sample analyses performed to provide information about the effect of the sample matrix on analyte recovery and measurement within the project samples. To create the MS/MSD, a project sample is spiked with known quantities of analytes and the percent recovery is determined. Method Blank- An analytical control that is carried through the entire analytical procedure. The method blank is used to define the level of laboratory background and reagent contamination. A method blank is prepared and analyzed for every batch of samples at a minimum frequency of one per every 20 samples. To produce unqualified data, the result of the method blank analysis is required to be less than the MRL and less than 5 times the amount of analyte found in any project sample. Minimum Reporting Level (MRL) - the smallest measured concentration of a substance that can be reliably measured using a given analytical method. Peak Integrations - The output of many analytical instruments is a peak which represents the quantity of analyte in the sample. The instrument automatically integrates the peak area to provide the concentration ------- Data Review of Room I9A Project: Code: ESD-141A Page 4 of4 of the analyte; however, sometimes these peaks need to be manually integrated by the analyst. Precision - the degree of mutual agreement or repeatability among a series of individual results. Relative Percent Difference - The difference between two sample results divided by their mean and expressed as a percentage. Surrogate Spikes compounds similar to the target analytes in behavior and not typically found in the environment. They are used to help evaluate laboratory preparation and analysis performance for individual samples. The surrogate spike differs from the LCS (above) in that it is placed in each project sample to assess preparation and analytical efficiency. ------- 2/26/08 Manchester Environmental Laboratory Report
