Abstract

       The recent discovery of contamination in PCB sampling pads stored in the EPA Region 10
field equipment room occurred during a routine quality control analysis of these materials. 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.

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.

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.

Samples were acquired with mini-volumetric samplers operating for approximately 21-23 hours (depending on battery

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

Aroclor 1254 was detected in sixteen of the samples.

12.    Reporting Limits
Reporting limits are based on the lowest standard analyzed, final extract volume and overall background
from the matrix.

13.    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

                                                                            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.
