I. INTRODUCTION'
On July 21 & 22, 2006 personnel from Ramcon Environmental conducted a
source emissions test for APFO and PFOA particulate at the Fayetteville
works PFOA facility located in Fayetteville, North Carolina. Mr. Dale Sawyer
was the Ramcon project manager. Four test locations were sampled; Stack
exhaust (SST), Process scrubber (PSL), Building Exhaust Inlet (BEI), and
Building Exhaust Stack (BES). The testing program was to determine to
distribute of particulate emissions from each source and the final mass
emission rate from the stack.
The purpose of the test was to determine if the rate of particulate emissions
from this plant's stack exhaust (SST) is below or equal to the allowable
emissions limit set by US EPA and the State of North Carolina.

HL TEST PROCEDURES
The methods used during the test program are summarized in Table 1. The
cited methods are referenced and documented in 40 CFR Part 60 Appendix A
per the most recent update of the CFR. The only exceptions to the cited
methods occur in the Reference Method 5- Determination of Particulate
Matter Emissions from Stationary Sources. Section 1 provides description
of each modification and its justification. Section 2 will describe the cleaning
of the sample bottle and the sample storage.
For this test, the particulate catch was determined by chemical analysis instead
gravimetrically. The samples (one filter and liquid) were submitted for
chemical analysis.

SECTION 1
METHOD 5 MODIFICATIONS
The following modifications to Reference Method 5 are being recommended to improve
the collection of this material and enhance its detectability. These modifications do not
in any ways invalidate the basic sampling technique of the method. Unless otherwise
specified all other requirements of the method are to be followed.
Modification
Justification
Probeibox temperature set at no more than
• Assuming the stack gas is not
10' F above stack temperature
moisture saturated; this
modification allowed the collection
at a low temperature without
concern of moisture condensation
to wet the sample filter.
• If the stack is saturated, the method
guidelines will be followed.
Replace plain distilled water with distilled
This combination provided the best
water solution in the im in ers.
solution of absorbing this material.
Five (5) impinger train configuration
The modification was intended to
improve the collection of this
material by providing an additional
absorption zone. The impingers
were be charged as follows:
• Impingers1, 2 and 3 filled with
100-ml each of distilled water
solution.
• Impinger 4 was empty.
• Im in er 5 contained desiccant.
Post-test rinses were done using water
All rinses were combined with
solution instead of acetone.

Sample collection
All samples were properly labeled
and submitted to a lab to be
designated by DuPont for analysis.

SETION 2
SAMPLE PREPARATION
The samples were stored in prewashed high density polyethylene bottles. The prewash
protocol for bottles and glassware consisted of washing the bottle in 0.1N sulfuric acid,
rinsing in distilled/deionized water, followed by air drying in a dust free enclosure. At
no time were soaps or detereents used in the process as they may contain the target
analyte which is a surfactant. The bottles were placed in zip lock plastic bags for
transport and remained sealed until needed. Labels were affixed to the bottles prior to
their placement in the sealed in the zip lock plastic bag.
The sample filters were placed in a labeled, precleaned plastic bottle after use. Pre- and
post -weighing of the filters was not require since the analyte will be determined
chemically.
All liquid samples were stored in precleaned plastic bottle. The volume as well as all
necessary information was annotated on the bottle. Each bottle was tape closed to
prevent leaking.
A field blanks consisted of 500-ml of the water solution and one filter was reserved and
shipped with the field samples.
