1.0 INTRODUCTION
On February 4, 2009, Ms. Touchette with CPI and Mr. Haytham Kasem with S&ME met
at the former PCA facility in Matthews, North Carolina regarding the planned removal
and disposal of liner, tile and underlying tile setting bed located within two floor levels of
the on-site buildings. The location of the facility is indicated on Figure 1. Mr. Neal
McElveen and Mr. Mike Cashio with S&ME visited the facility on February 5, 2009 to
tour the area with the liner, tile and setting bed to be removed. The purpose of the
sampling was to 1) evaluate options for the disposal of the tile, setting bed, and liner
material and 2) evaluate potential exposure of chemicals likely to be present in the tile
and setting bed, during both the sampling and removal of the tile and setting bed.
2.0 BACKGROUND
The tile is a red-brown quarry tile approximately 6-inches square. The tile is underlain
by approximately 4 inches of cement/sand material. In addition, approximately 50% of
the lower floor area is covered with a Rhino rubber liner, portions of which have no
underlying tile. The liner, tile, and bedding material are located in areas of chemical
storage and use in film processing. The upper floor drains to centrally located floor
drains which are piped to the lower floor. The lower floor drains to a trench system that
flows to a pretreatment system. Possible chemicals that could be present include silver,
cadmium, chromium, lead, cyanide, ammonia, (from ammonium thiosulfate), sulfides,
hydrogen sulfide, and formaldehyde. However, the use of liquids or material with
cyanides could not be ruled out based on lack of information of past operations.
Based on a February 18, 2009 site meeting with Mr. Ted Hellmann and others with CPI
Corp, Mr. McElveen and Mr. Al Quarles with S&ME, and Mr. Malcolm Whitley with
Concord Industrial Services Company, Inc., an extra area of the lower floor currently
occupied by office space was discovered to have been previously part of the lower floor
processing area. CPI Corp. personnel had uncovered the carpet VTI tile in several areas
exposing the same quarry tile as in the processing area and two concrete-filled trenches
that connect to the trenches in the current processing area. Thus, Mr. Hellmann requested
that this area and the adjacent piping chase area be included in the sampling plan.
We understand that a sample of the setting bed material was collected by CPI personnel
on January 7, 2009 and analyzed for the eight RCRA metals following TCLP Extraction
and for total sulfide. The concentrations of the RCRA metals were not above hazardous
waste limits. Sulfide was not detected above the laboratory method detection limit of 10
milligrams per kilogram.

3.0 FIELD ACTIVITIES
The following field activities were performed on February 25, 2009 during the sample
collection:
• S&ME collected samples composite of the tile, setting bed, and liner from Areas
A through F from the chemical mixing rooms on the upper and lower floors of the
building, as indicated on the attached Figures 2a, and 2b. Lower and Upper
Sample Location Plans. The tile and setting bed at each location were uncovered
and removed by an S&ME employee using an electric jack hammer. In addition,
background samples of tile and underlying concrete were collected in the upper
floor shipping/receiving room.
• The floor areas were divided into six areas. Samples of the tile, setting bed and
liner (if present) were collected from five to six locations within each area. The
five to six samples of each material type from each area were composited to form
one laboratory sample per type per area. The setting bed samples were
composited at the site. The tile and liner samples were returned to S&ME’s office
and were crushed or cut with pre-cleaned equipment.
• During sample collection, two large fans were provided by CPI personnel that
moved air across the sampling areas. No apparent dust was generated during the
sampling activities.
3.1 Tile Samples
At each Area S&ME removed two tiles for access to the underlying setting bed material.
Tile from each of the six locations within each area was placed in a plastic sealable bag
and labeled with the area of collection. The tile from each area was crushed at S&ME’s
office using material testing equipment and mixed to form one laboratory sample per
area. From the mixed sample, the laboratory containers were filled and placed on ice
prior to transport to the laboratory.
3.2 Setting Bed Samples
After removing the tile, S&ME removed and collected a sample of the setting bed
material to a depth of ~3 to 4 inches (without penetrating the underlying concrete floor).
The samples from each area were placed in a stainless steel bowl and mixed. From the
mixed sample, the laboratory containers were filled on site, and placed on ice prior to
transport to the laboratory.
3.3 Liner Samples
Samples of the Rhino rubber liner were composited from two areas (B and C) in the
lower floor area, for laboratory analysis. The samples were cut into small pieces with tin
snips, and placed in a plastic bag and mixed by shaking and rotating the bag. From the
mixed sample, the laboratory containers were filled and placed on ice prior to transport to
the laboratory.

3.4 Background Samples
One additional sample of the tile and setting bed material was be collected in the
shipping/receiving area, a location not reported to have used chemicals, for the purposes
of a background or baseline sample. Note that the material underlying the tile was
concrete and not bedding material as was encountered in the processing areas.
3.5 Laboratory Analysis
S&ME submitted the samples to Pace Analytical Services Inc., of Huntersville, North
Carolina a state-certified laboratory for the analysis of the following parameters, as
would be required for disposal acceptance by the Allied Waste into their Subtitle D
landfill in Concord, North Carolina:
• Total RCRA Metals (arsenic, barium, cadmium, chromium, lead, mercury,
selenium, and silver).
• Reactivity (Sulfide and Cyanide)
• Corrosivity (aka: pH)
• Ignitability (aka: flashpoint)
• TCLP-silver (selected samples with total silver concentrations greater than 20
times the hazardous waste limits.
4.0 AIR MONITORING
During the February 25, 2009 collection of the tile, bedding material and liner samples,
S&ME collected samples of the breathing zone using various sampling methods to
evaluate potential exposure to S&ME employees from contaminants potentially present
in the sampling media. The contaminants selected for monitoring were based on
information provided by CPI Corp. The locations of the samples are described in Tables
1 through 5 and are depicted on Figures 2A and 2B. The sampling included the
following contaminants:
• Lead
• Cadmium
• Soluble Barium
• Chromium
• Silver
• Ammonia
• Hydrogen Sulfide
• Formaldehyde
• Hydrogen Cyanide
4.1 Procedures
4.1.1 Lead, Cadmium, Chromium, and Silver
One sample was collected from an S&ME employee’ breathing zone while operating a
jackhammer during environmental sampling activities and one sample was collected from
an S&ME employee’s breathing zone while collecting tile, setting bed, and liner samples.
Environmental Sampling Report S&ME Project No. 1354-09-016
Former PCA Facility, Matthews, North Carolina April 1, 2009

Air sampling pumps were calibrated to a flow rate of 2.0 liters per minute before and
after the sampling event with suitable media (37 mm mixed cellulose ester filters in
polystyrene cassettes) inline.
4.1.2 Soluble Barium
One sample was collected from an S&ME employee’ breathing zone while operating a
jackhammer during environmental sampling activities. The air sampling pump was
calibrated to a flow rate of 2.0 liters per minute before and after the sampling event with
suitable media (37 mm mixed cellulose ester filters in polystyrene cassettes) inline.
4.1.3 Silver
Since multiple metals analysis frequently produces a low-biased result for silver, an
additional sample was submitted for a separate silver (only) analysis. One sample was
collected from an S&ME employee’s breathing zone while collecting tile, setting bed,
and liner samples. The air sampling pump was calibrated to a flow rate of 2.0 liters per
minute before and after the sampling event with suitable media (37 mm mixed cellulose
ester filters in polystyrene cassettes) inline.
Personnel air monitoring samples and corresponding blanks were then submitted under
proper chain of custody to Galson Laboratories (Galson) in East Syracuse, New York for
analysis. Galson is accredited in industrial hygiene analysis by the American Industrial
Hygiene Association.
4.1.4 Ammonia, Hydrogen Sulfide, Hydrogen Cyanide, and Formaldehyde,
Up to 14 samples were collected for each contaminant during initial flooring disturbance,
sample collection, and subsequent tile crushing using Gastec detector tubes and a piston
pump. Each sample was collected near breathing zone level.
4.2 Results
Results of the analyses and detector tube readings are summarized in the Tables 1
through 5.
Metals: The results of the metal analyses are summarized in Table 1. Silver was the only
metal detected above laboratory method detection limits, with concentrations ranging
from 0.0022 to 0.0031 milligrams per cubic meter (mg/m3). The North Carolina
Occupational Safety and Health Administration (NC OSHA) Permissible Exposure Level
(PEL) over an 8-hour Time Weighted Average (TWA) is 0.01 mg/m3.
Ammonia: The results of the ammonia analyses are summarized in Table 2. Ammonia
was detected at a concentration of 1 ppm in two samples: during the collection of samples
in area E (sample E3) and during the preparation of the tile sample Tile-D. The NC
OSHA PEL over an 8-hour TWA is 50 parts per million.
Hydrogen Sulfide and Hydrogen Cyanide: The results of the hydrogen sulfide and
hydrogen cyanide are summarized in Tables 3 and 4, respectively. These contaminants
were not detected.

Formaldehyde: The results of the formaldehyde analyses are summarized in Table 5.
Elevated levels of formaldehyde (0.2 ppm to 0.5 ppm) were detected during detector tube
sampling. The NC OSHA levels as 8-hour TWAs are as follows: Action Level of 0.5
ppm as an 8-hour TWA; PEL of 0.75 ppm as an 8-hour TWA; and Short Term Exposure
Limit (STEL) of 2 ppm as a 15-minute short-term exposure.
S&ME staff members were instructed to stop work and wait outdoors until such levels
dissipated. The area was later reevaluated and no detectible levels of formaldehyde were
found to be present. S&ME personnel returned to work and completed the shift without
further incident.
5.0 DECONTAMINATION AND WASTE DISPOSAL
The sampling tools were cleaned prior to and following the collection of each composite
sample by type using potable water, liquinox/water mixture and deionized water. New
disposable nitrile gloves were used between each composite sample collection. The
gloves, paper towels and excess tile and liner sample were placed in a plastic trash bag
for later disposal with the tile, setting bed and liner material.
6.0 TILE, SETTING BED AND LINER ANALYTICAL RESULTS
As a “rule of thumb,” total metal concentrations in units of milligrams per kilogram
(mg/kg) greater than 20 times the hazardous waste limits of leachable metals in units of
milligrams per liter (mg/L), would be considered indicative of hazardous waste, unless
the samples are also analyzed for actual leachable metal concentrations using the Toxicity
Characteristic Leaching Procedure (TCLP).
6.1 Tile Samples
Laboratory analytical results of the tile samples did not indicate the presence of metals in
excess of 20 times the hazardous waste limits. Analysis of the samples for pH, Reactive
Sulfide, Reactive Cyanide, and Flashpoint found these to be below hazardous limits for
the purpose of disposal. Table 6 summarizes the analytical results of the tile samples.
6.2 Setting Bed Samples
Samples obtained from the tile setting bed for sample areas B, C, and D were found to
contain total silver at concentrations over the “20 times hazardous waste limit” value of
100 mg/kg. The samples were reported to contain 136 mg/kg for sample Bedding-B, 171
mg/kg for sample Bedding-C, and 223 mg/kg for sample Bedding-D. These samples
were subsequently analyzed for leachable silver using TCLP, with results ranging from
0.15 to 0.23 mg/L, compared to the hazardous waste limit of 5 mg/kg.
Analysis of the samples for pH, Reactive Sulfide, Reactive Cyanide, and Flashpoint
found these to be below hazardous limits for the purpose of disposal. Table 6
summarizes the analytical results of the tile samples.

6.3 Liner Samples
Laboratory analytical results of the Liner samples indicated the presence of silver at a
concentration in excess of the “20 times hazardous waste limit” value in sample Liner B
(332 mg/kg). This sample was subsequently analyzed for leachable silver using TCLP,
with a resulting concentration of 0.11 mg/kg, compared to the hazardous waste limit of 5
mg/L.
Analysis of the samples for pH, Reactive Sulfide, Reactive Cyanide, and Flashpoint
found these to be below hazardous limits for the purpose of disposal. Table 6
summarizes the analytical results of the tile samples.
7.0 CONCLUSIONS
7.1 Vapor Monitoring
Personnel air sampling results did not indicate exposures above the NC OSHA PELs.
Silver and formaldehyde were the only contaminants detected during the collection of the
tile, setting bed and liner samples. Formaldehyde was detected at the NC OSHA Action
Level of 0.5 ppm in one sample.
The construction activities during the removal of the tile, setting bed and liner material
from the upper and lower process areas are likely to be more aggressive than the
sampling activities. Thus there is a potential that the contaminants of concern may be
released into the breathing zone at higher concentrations that those detected during
sampling activities, and concentrations may exceed the NC OSHA PELs.
7.2 Tile, Setting Bed and Liner Disposal
The results of the tile, setting bed and liner sampling and analysis were below hazardous
waste limits. Thus, the material may be disposed as a non-hazardous special waste, at a
permitted facility such as the BFI Landfill in Concord, North Carolina.
8.0 RECOMENDATIONS
8.1 During Material Removal
We understand that CPI plans to remove the tile, setting bed material and liner and
dispose of these materials off-site. S&ME anticipates that the removal activities would
be more aggressive than the sampling activities that could result in a greater emission of
volatiles and the generation of dust, with the potential for higher concentrations of
contaminants in the breathing zone than those detected during the sampling activities.
Based on S&ME’s air and material sampling results and the possible contaminants
present in the materials, we recommend the following actions during the removal of the
tile, setting bed and liner materials:
1. Air monitoring of the breathing zone and workers to document potential or actual
exposure levels compared to action levels, PELs or STELs. Since silver and the
other metals are tested by laboratory methods, the exposure of workers above
PELs would not be evident until after exposure has occurred. Thus, engineering

controls as recommended below, would reduce the potential for exposure of these
non-volatile contaminants during the removal activities.
2. Additional ventilation of the working areas during material removal and handling
activities. Such ventilation may consist of additional fans moving outside air into
the working area and moving inside air to the outside.
3. Moisture controls to reduce or eliminate the generation of dust. Such controls
may include wetting the material during removal or using misting fans.
8.2 Waste Disposal
S&ME recommends submitting the laboratory reports and a waste profile to Allied Waste
for their approval for the disposal of the waste at their subtitle D BFI Landfill located in
Concord, North Carolina.
8.3 Post-Removal Concrete Condition Evaluation
Following removal of the tile, liner and bedding material, S&ME recommends a visual
evaluation of the integrity of the underlying concrete floor. Based on the evaluation
results, sampling of the concrete and possibly the soil beneath the concrete may be
recommended.
