1.0 INTRODUCTION
The United States Environmental Protection Agency (USEPA) is investigating the asphalt
concrete production source category to identify and quantify emissions of hazardous air
pollutants (HAPs) from rotary aggregate dryers used at these facilities. There are two types of
rotary drum dryers in use at asphalt concrete production plants; parallel flow, wherein the
direction of travel of the drying aggregate is the same as the direction of travel of the burner
exhaust gases, and counter flow, wherein the aggregate and exhaust gas flows are opposite to
each other. On May 7, 1997, a work assignment was issued by EPA's Office of Air Quality
Planning and Standards, Emissions Measurement Center, (OAQPS, EMC) to Pacific
Environmental Services, Inc. (PES), of Research Triangle Park, North Carolina. The work
assignment specified that emissions testing for HAPs be conducted on one of each type of
aggregate dryer. Two candidate facilities were therefore identified and selected as host facilities
for the testing program.
This document describes the test procedures, results, and quality assurance procedures
that were employed during the testing of a counter flow rotary drum aggregate dryer, which was
located at Asphalt Plant "A" in Clayton, North Carolina. The facility was identified as a
candidate by EPA due to its location close to EPA facilities in Research Triangle Park, North
Carolina, and because it is typical of counter flow rotary dryers in the asphalt production source
category. The results of the emissions testing program conducted at a facility employing a
parallel flow rotary aggregate dryer are presented in a separate report.
The scope of the work assignment was to plan and conduct an air emissions testing
program to quantify emission rates of HAPs from the rotary aggregate drier located at Asphalt
Plant "A". The planning and testing phase of the program was conducted under EPA Contract
No. 68D20162, Work Assignment No. 4-13. Because the period of performance of the contract
expired on September 30, 1997, PES was issued a second work assignment to complete the data
reduction, a portion of the analysis, and the preparation of the draft report, which was completed
under EPA Contract No. 68D70002, Work Assignment No. 0-005. This final report incorporates
comments from EPA and the National Asphalt Pavement Association, and includes a process
description and process data collected by EPA's Emission Standards Division (BSD) contractor.
The final report was prepared under EPA Contract No. 68D70069, Work Assignment No. 2-09.
The primary objective of the test program was to obtain data on the controlled and
uncontrolled emissions of poly chlorinated dibenzo-p-dioxins (PCDDs or "dioxins") and
polychlorinated dibenzofurans (PCDFs or "furans"), particulate matter (PM), and metallic HAP
and non-HAP compounds from rotary drum dryers. A secondary objective of the test program
was to observe and record plume opacity. The data will be used by ESD to determine whether
1-1
-------
HAPs are emitted at levels that would justify regulation under the Maximum Achievable Control
Technology (MACT) program.
The test program at Asphalt Plant "A" was completed during the week of August 18,
1997. The basic test methods that were employed were EPA Test Methods 1 (sample point
location), 2 (gas velocity), 3 (gas molecular weight), 4 (gas moisture volume content),
5 (paniculate matter concentration), 9 (plume opacity), 23 (dioxin and furan concentration) and
29 (metals concentrations). PM concentrations were determined by using tared filters in the
Method 29 sampling train. The work assignment issued by EMC called for testing to be
conducted during the production of asphalt with Reclaimed Asphalt Pavement, or RAP. At the
request of EPA, an additional sampling run was conducted while the makeup material consisted
solely of virgin aggregate. The results of all four of the test runs are presented in Section 2.0 of
this report. The work assignment also specified testing to quantify both controlled and
uncontrolled emissions. However, during the initial stages of testing of the uncontrolled dryer
exhaust, sampling had to be discontinued due to extremely high grain loading conditions which
far exceeded the sampling capacity of the Method 23 and Method 29 sampling trains. After
telephone consultations with personnel from ESD and EMC, testing activities of the uncontrolled
emissions were deleted from the scope of work.
PES used three subcontractors to assist in the completion of this testing effort. Deeco,
Inc. (DEECO) of Raleigh, North Carolina; Triangle Laboratories, Inc. (TLI) of Durham, North
Carolina, and Atlantic Technical Services, Inc. (ATS) of Chapel Hill, North Carolina. DEECO
provided source testing support at the inlet locations (prior to cancellation of these testing
activities), visual emissions observations of controlled emissions, and sample recovery support.
TLI provided analytical services for the quantification of PCDDs/PCDFs and metals in the
collected samples, and ATS provided on-site sampling support as well as support during
preparation of the site test plan, draft report and calculation of the emissions test results.
The test program organization and major lines of communication are presented in
Figure 1.1. The PES Project Manager communicated directly with the EPA Work Assignment
Manager (WAM) and coordinated all of the on-site testing activities. The sampling locations at
Asphalt Plant "A" are shown in Figure 1.2.

2.0 SUMMARY OF RESULTS
This section summarizes the results of the testing program at the Asphalt Plant "A". The
following pages present the times and durations of each of the sampling runs that were
conducted, the sampling parameters during each run, the effluent gas parameters, and the
concentrations and mass emission rates of the target HAPs. Sampling of emissions was
conducted on three consecutive days from August 19, 1997 through August 21, 1997, during
which time four sampling runs for both dioxins and furans (PCDDs/PCDFs) and metals were
conducted. Table 2.1 presents the "Emissions Test Log" which summarizes clock times, target
pollutants, and downtime due to filter and port changes for each of the Method 23 and Method 29
sampling runs attempted. The results of the PCDDs/PCDFs sampling during asphalt production
with RAP are presented in Tables 2.2 through 2.7, and the results of the PCDDs/PCDFs
sampling conducted during production with virgin aggregate are presented in Tables 2.8 through
2.10. The results of the particulate matter (PM) and metals sampling runs conducted during RAP
addition are presented in Tables 2.11 through 2.16, and the results of the PM and metals runs
conducted during asphalt production with virgin aggregate are presented in Tables 2.17 through
2.19.
2.1 OXYGEN AND CARBON DIOXIDE MEASUREMENTS
Concurrent with the Method 23 and Method 29 sampling at the baghouse outlet, bag
samples of the effluent gas were collected and analyzed using an Orsat® apparatus to determine
oxygen (O2) and carbon dioxide (CO2) concentrations for the purpose of calculating stack gas
molecular weight. The O2 and CO2 concentrations presented for the first sampling run are the
average of the O2 and CO2 concentrations measured during runs two and three. The diluent
concentrations are presented in this manner because the results of the analyses from the first run
were misplaced during the field testing portion of the test program and were not recovered. The
diluent concentrations measured during the second and third runs should be representative of the
concentrations during the first run, because the operating conditions were essentially unchanged.
2.2 PCDDs/PCDFs MEASUREMENTS
PCDDs/PCDFs results are presented as 1) actual concentrations and mass emission rates,
2) concentrations adjusted to 7 % O2, and 3) concentrations adjusted to 7 % O2 and 2378 terra-
chlorinated dibenzo-p-dioxin (TCDD) toxic equivalent basis. Adjustment of the congeners to a
2378 toxic equivalent basis was accomplished using the Toxic Equivalency Factor (TEF) values
developed by the NATO Committee on the Challenges of Modern Society, August 1988.

Test runs were aborted due to high grain loading conditions at the baghouse inlet sampling location.
Subsequent test runs canceled.
The Method 23 sample fractions consisted of a sample train front-half solvent rinse, a
particulate filter, a back-half solvent rinse, and an XAD®-2 sorbent resin module. During
analysis, each of the sample fractions was extracted, concentrated, combined, and analyzed using
a Gas Chromatograph with a Mass Spectrometer detector (GC/MS), according the procedures
outlined in Method 23. During analysis, the combined sample extract was separated with a DB-5
capillary column. Where the results of that analysis indicated the presence of 2378 TCDF
congeners, the analysis was repeated using a DB-225 capillary column so that the TCDF
congeners could be more readily separated and quantified.
The results of the analyses indicated the presence of several congeners that were qualified
as Estimated Maximum Possible Concentrations, or EMPCs, From time to time during the
Method 23 analyses, a peak elutes at the position expected for a particular congener, but the peak
fails validation based on the theoretical split of chlorine isotopes. That is to say that the number
of Cl35 isotopes and the number of Cl37 isotopes attached to the PCDDs/PCDFs congeners should
agree with the C135/C137 ratio found in nature. For each congener, this ratio must agree within
15%. If the mass ratio of chlorine isotopes does not agree with the natural chlorine isotope ratio,
then the peak is flagged as an EMPC.
The values presented as "Total PCDDs" are the sum of the "12346789 OCDD"
polychlorinated dibenzo-p-dioxin and all of the dioxins labeled "Total"; "Total PCDFs" values
are the sum of the "12346789 OCDF" polychlorinated dibenzofuran and all of the furans labeled
2-3
-------
"Total". "Total PCDDs + Total PCDFs" values are the sum of the "Total PCDDs" and "Total
PCDFs" values. Values that have been qualified as being EMPC have been included in the sums.
Concentrations and emission rates based on or including EMPC values are denoted by braces
2.2.1 Baghouse Inlet - Asphalt Production with RAP
Table 2.2 summarizes the PCDDs/PCDFs emissions sampling and stack gas parameters
at the baghouse inlet. For reasons stated previously, only one sampling run was conducted at this
location. Sampling was aborted approximately 10 minutes into the sample run when the
isokinetic sampling rate could not be maintained due to blockage of the sampling nozzle and the
probe liner with particulate matter. Sampling was halted at both the inlet and the outlet
locations, the sample train was disassembled, and large amounts of particulate matter were
removed from the sample nozzle, glass liner, and front half of the filter housing into a pre-
cleaned glass sample jar. The sample train was then reassembled, leak checked, and the attempt
was made to continue sampling. After approximately 1 0 more minutes of sampling, the sample
train plugged again, and the decision was made by the EPA WAM to cancel testing of the
uncontrolled dryer emissions.
Although the test cannot be considered to be valid due to the low sample volume of
10.94 dry standard cubic feet (dscf), which is equivalent to 0.310 dry standard cubic meters
(dscm), PES, at the direction of EPA, recovered the sample fractions and submitted them for
analysis by the subcontracting laboratory. The inlet gas temperature was 230 °F and contained
5.3% by volume CO2, 13.1% by volume O2, and 26.5% by volume moisture. The inlet gas
volumetric flow rate was 30,1 19 actual cubic feet per minute (acfm) which is equivalent to
16,819 dry standard cubic feet per minute (dscfm) or 476.3 dry standard cubic meters per minute
(dscmm).
Table 2.3 presents the PCDDs/PCDFs concentrations of the baghouse inlet gas stream.
The concentration of total PCDDs was 151 nanograms per dry standard cubic meter (ng/dscm),
and the concentration of total PCDFs was 2.9 ng/dscm. The concentration of total
PCDDs/PCDFs was 154 ng/dscm. The total PCDDs mass emission rate was 4,305 micrograms
per hour (ng/hr) and the total PCDFs mass emission rate was 83.9 |ig/hr. The mass emission rate
of total PCDDs/PCDFs was 4,389 ug/hr.
The PCDDs/PCDFs 2378 toxic equivalent concentrations at the baghouse inlet are
presented in Table 2.4. Each PCDDs/PCDFs congener has been corrected to a reference O2
concentration of 7%, and then multiplied by the appropriate NATO 2378 TCDD toxic equivalent
factor. Because the measured oxygen concentration was 13.1% by volume, the corrected
concentrations are greater than the actual concentrations. The concentration of total PCDDs was
268 ng/dscm, corrected to 7% O2 and the concentration of total PCDFs was 5.23 ng/dscm
corrected to 7% O2, therefore the total PCDDs/PCDFs concentration was 274 ng/dscm, corrected
to 7% O2. The total PCDDs concentration was 0.398 ng/dscm corrected to 7% O2 and
2378-TCDD equivalents, and the total concentration of PCDFs was 0.143 ng/dscm corrected to
7% O2 and 2378-TCDD equivalents. The concentration of total PCDDs/PCDFs corrected to 7%

-------
O2 and 2378-TCDD equivalents at the baghouse inlet gas stream was 0.541 ng/dscm. The reader
is reminded that assumptions made on the basis of the results of testing at inlet location should
be made with care, due to the low sample volume and because only one sampling run was
conducted at the inlet location instead of the three normally preferred.
2.2.2 Baghouse Outlet - Asphalt Production with RAP
PES conducted three Method 23 sampling runs at the baghouse outlet during the production
of asphalt concrete with RAP. Table 2.5 summarizes the PCDDs/PCDFs sampling and exhaust
gas parameters. Each sampling run was 240 minutes in duration, with the exception of the third
test run which was 200 minutes. The third test run was stopped early at the direction of the EPA
WAM due to storms and lightning in the vicinity of the test location. The (3-run) average
sample volume was 153.390 dscf or 4.344 dscm. The (3-run) average stack gas temperature was
206°F and contained 5.3 % CO2 by volume, 13.1 % O2 by volume, and 21.6% moisture by
volume. The (3-run) average stack gas volumetric flow rate was 36,596 acfm or 22,533 dscfm or
638.1 dscmm.
Table 2.6 presents the PCDDs/PCDFs concentrations and emission rates at the baghouse
exhaust. The (3-run) average concentration of total PCDDs was 0.127 ng/dscm, and the (3-run)
average concentration of total PCDF in the stack gas was 0.0796 ng/dscm. The (3-run) average
concentration of total PCDDs/PCDFs was 0.207 ng/dscm. These values corresponded to average
emission rates of 4.69 ug/hr for total PCDDs, 3.04 ug/hr for total PCDFs, and 7.72 ug/hr for
total PCDDs/PCDFs compounds.
Table 2.7 presents the PCDDs/PCDFs concentrations adjusted to a reference diluent
concentration of 7% O2. Since the oxygen concentration of the effluent gas was greater than 7%
for every sampling run, the adjusted PCDDs/PCDFs values are greater than the actual values.
The (3-run) average adjusted concentration of total PCDDs was 0.227 ng/dscm @ 7% O2, the
(3-run) average adjusted concentration of total PCDFs was 0.142 ng/dscm @ 7% O2, and the (3-
run) average adjusted concentration of total PCDDs/PCDFs was 0.369 ng/dscm @ 7% O2. Also
presented in Table 2.7 are the PCDDs and PCDFs concentrations at 7 % O2, adjusted to a toxicity
equivalent to that of 2378 TCDD. The (3-run) average concentration of PCDDs was 0.000240
ng/dscm when presented on a 2378-TCDD toxic equivalent basis, the (3-run) average
concentration of PCDFs was 0.00590 ng/dscm when presented on a 2378-TCDD toxic equivalent
basis, and the concentration of total PCDDs/PCDFs compounds was 0.00830 ng/dscm, corrected
to a 2378-TCDD toxic equivalent basis, at a reference diluent concentration of 7% O2.
2.2.3 Baghouse Outlet - Asphalt Production without RAP
At the request of EPA, PES conducted one test run at the baghouse outlet during the
production of asphalt concrete without the addition of RAP. Table 2.8 summarizes the
PCDDs/PCDFs emissions sampling. The total sampling time for the test run was 240 minutes.
The sample volume was 165.621 dscf or 4.690 dscm. The stack gas temperature was 180 °F and
contained 3.2 % C02,10.8 % O2, and 18.9 % moisture. The stack gas volumetric flow rate was
37,027 acfm or 24,580 dscfm or 696.0 dscmm.

Table 2.9 presents the PCDDs/PCDFs stack gas concentrations and emission rates. The
concentration of total PCDDs was 0.0527 ng/dscm, and the concentration of PCDFs was 0.0576
ng/dscm. The concentration of total PCDDs/PCDFs was 0.110 ng/dscm. These values
corresponded to emission rates of 2.20 ug/hr for PCDDs, 2.40 ug/hr for PCDFs and a total
emission rate of 4.60 ug/hr for all PCDDs/PCDFs. Table 2.10 presents the PCDDs/PCDFs
concentrations adjusted to 7% O2. The measured stack gas O2 concentration was 10.8 %.
Therefore, the adjusted PCDDs/PCDFs concentrations were greater than the actual
concentrations. The adjusted concentration of total PCDDs was 0.725 ng/dscm @ 7 % O2, and
0.0792 ng/dscm @ 7 %O2 for PCDFs. The adjusted concentration of total PCDDs/PCDFs was
0.152 ng/dscm @ 7 % O2. Table 2.10 also presents the adjusted concentrations in 2378 toxic
equivalents. The TEF concentration for total PCDDs/PCDFs was 0.004 ng/dscm.
2.3 PARTICIPATE MATTER AND METALS MEASUREMENTS
2.3.1 Baghouse Inlet - Asphalt Production with RAP
As stated previously, only one sampling test run was attempted at the baghouse inlet.
Table 2.11 summarizes the particulate matter/metals emissions sampling and gas parameters at
the baghouse inlet. The total sampling time was 20 minutes. The sample volume was 10.491
dscf or 0.297 dscm. The exhaust gas temperature was 230 °F and contained 5.3% CO2, 13.1%
O2, and 26.1% moisture. The exhaust gas volumetric flow rate was 23,773 acfm or 13,353 dscfm
or 378 dscmm. Although the test was not valid due to a low sample volume, the sample was
recovered, extracted, and analyzed at the instruction of the EPA WAM to determine particulate
matter and metals catch weights.
Table 2.12 summarizes the exhaust gas particulate matter concentrations and emission
rates at the baghouse inlet. The concentration was 63.7 grains per dry standard cubic foot
(gr/dscf) or 146 grams per dry standard cubic meter (g/dscm). The concentrations are also shown
adjusted to 7% O2. The average mass emission rate was 7,296 pounds per hour (Ib/hr) or
3,310 kilograms per hour (kg/hr).
Table 2.13 summarizes the exhaust gas metals concentrations and emission rates. Most
of the target metals were found to be present in the sample. Concentrations ranged from 11,944
micrograms per dry standard cubic meter (ug/dscm) for phosphorus to 3.26 ug/dscm for
selenium.

2.3.2 Baghouse Outlet - Asphalt Production with RAP
Table 2.14 summarizes the particulate matter/metals emissions sampling and stack gas
parameters. The total sampling time for each test run was 240 minutes, except the third test run
which was 200 minutes. The average sample volume was 166.137 dscf or 4.704 dscm. The
average stack gas temperature was 203 °F and contained 5.3% CO2,13.1% O2, and 20.2%
moisture. The average stack gas volumetric flow rate was 37,437 acftn or 23,661 dscfm or
670 dscrnm.
Table 2.15 summarizes the stack gas particulate matter concentrations and emission rates.
The average concentration was 0.0176 gr/dscf or 0.0402 g/dscm. The concentrations are also
shown adjusted to 7% O2. The average emission rate was 3.43 lb/hr or 1.56 kg/hr.
Table 2.16 summarizes the stack gas metals concentrations and emission rates. Most of
the target metals were found to be present in all three samples. Average concentrations ranged
from 0.0231 jag/dscm for antimony to 45.5 ng/dscm for phosphorus. Beryllium was not detected
during any of the sampling runs, cobalt was only detected during the first run, and silver and
thallium were only detected during two of the sampling runs. There were two instances where
the target metal was detected, but was present at a concentration less than the concentration
detected in the reagent blank samples. In these two cases (antimony during the third run and
silver during the second run) a value of 0.00 has been reported.
2.3.3 Baghouse Outlet - Asphalt Production without RAP
PES conducted one test run at the baghouse outlet during asphalt production without
RAP. Table 2.17 summarizes the particulate matter/metals emissions sampling and stack gas
parameters. The total sampling time for the test run was 240 minutes. The sample volume was
168.390 dscf or 4.768 dscm. The stack gas temperature was 180°F and contained 3.2 % CO2,
10.8 % O2, and 18.7 % moisture. The stack gas volumetric flow rate was 36,415 acfm or 24,240
dscfrn or 686 dscmm.
Table 2.18 summarizes the stack gas particulate matter concentrations and emission rates.
The concentration was 0.00122 gr/dscf or 0.00279 g/dscm. The concentrations are also shown
adjusted to 7% O2. The average PM emission rate was 0.253 lb/hr or 0.115 kg/hr.
Table 2.19 summarizes the stack gas metals concentrations and emission rates. Most of
the target metals were present in the sample. Concentrations ranged from 0.0436 ng/dscm for
silver to 15.2 (ig/dscm for phosphorus. In general, the emissions of metals during production
without RAP was less that emissions during production with RAP. In the cases of antimony,
silver, and selenium, the quantities detected in the sample were less than the quantities detected
in the reagent blanks. For these three targets, values of 0.00 have been reported.

2.4 DETERMINATION OF VISIBLE EMISSIONS
Visible Emissions Observations (VEOs) of the stack exhaust were made during the
testing by a certified observer. Observations were made simultaneously with the testing, except
during the first run when VEOs were suspended during the period from 1207 to 1304 when the
location of the sun was directly over the observer. The average opacity during asphalt
production with RAP is presented along with the outlet stack gas parameters in Table 2.14. For
each run the calculated average opacities were 2.15,1.21, and 0.702%. Since VEO observations
are recorded in 5% increments, the average opacity during these runs is more properly reported
as less than 5% opacity. Also presented are the maximum single opacity observed, the maximum
6-minute block average, and the maximum 6-minute rolling average during each test run. During
the production of asphalt without RAP, the the calculated average opacity of the outlet gas
stream was 0.104%; however, this result is more properly reported as an average opacity of
< 5 %. The opacity data during production with RAP are presented along with the stack gas
parameters in Table 2.17.

3.0 PROCESS DESCRIPTION
The Asphalt Plant "A" concrete production facility in Clayton, North Carolina, has been
in operation since 1989. It is a counter flow, continuous drum mix process. The dryer/mixer is
an ASTEC double-barrel drum, a variation of the drum mixer, with a rated capacity of 400 tons
per hour (tph). The plant has the capability of producing up to 15 asphalt mix types, with or
without the use of RAP.
Asphalt concrete, called "hot mix asphalt" (HMA) by the industry, is a mixture of well-
graded, high quality aggregate that is heated and mixed with liquid asphalt cement to produce
paving material. The characteristics of the asphalt concrete are determined by the relative
amounts and types of aggregate (and RAP) used. In the asphalt reclamation process,
old asphalt pavement is removed from the road surface, transported to the plant, and crushed and
screened to the appropriate size for further processing.
In the counter flow continuous double-barrel drum mix process, virgin aggregate of
various sizes is fed to the drum by cold feed controls in proportions dictated by the final mix
specifications. Aggregate is delivered by conveyor belt to the inner drum, entering at the
opposite end of the burner (hence, the descriptor "counter" flow). The aggregate moves toward
the burner within the inner drum and is dried. The hot aggregate falls to the outer drum through
holes at the burner end of the inner drum. As the hot aggregate moves along the outer drum,
liquid asphalt cement and conditioner are delivered to the drum mixer by a variable flow pump
that is electronically linked to the aggregate feed weigh scales. Recycled dust from the control
system and RAP (if used) are also added into the outer drum. The resulting asphalt concrete
mixture is discharged from the outer drum and conveyed to storage silos for delivery to trucks.
There are five cold storage bins and three hot mix storage silos at Asphalt Plant "A". The
hot mix storage silo capacity is 200 tons each, for a total of 600 tons. There «re three screens for
aggregate sizing and one 52,000 gallon (130 ton) heated asphalt cement storage vessel. The
plant uses virgin and recycled No. 2 fuel oil, supplied by Noble Oil Services, Inc., for all its
process fuel needs. A fuel assay report is presented in Appendix A. Virgin fuel oil is used
during extremely cold weather and/or if there is a fuel-related problem with the burner.
Therefore, virgin fuel is usually only used during the winter months (January/February). The
amount of energy needed from the fuel for the asphalt production process is 225,600 BTU per
ton of asphalt produced. The hot gas contact time with the aggregate is approximately one
minute, and the process time from the beginning of the drum to the coater is approximately six
minutes.
3-1
-------
Asphalt Plant "A" uses an asphalt cement (AC) called AC-20, obtained from Citgo of
Wilmington, North Carolina. An anti-strip conditioner, called Perma-Tac (from Arr-Maz), is
sometimes used; antistrip is required for all North Carolina Department of Transportation jobs.
For PM control, the Asphalt Plant "A" facility uses a fabric filter. The fabric filter is an ASTEC
Pulse-Jet, equipped with 1,024 14-ounce Nomex bags and is operated with an air-to-cloth ratio of
5.54:1 feet per minute. The process exits the drum and coaler and proceeds into the fabric filter,
where it is exhausted through a stack. As mentioned above, the dust collected by the PM control
devices is recycled to the process.
Data were taken at 15-minute intervals during the entire "test period" (i.e., the time period
when at least one manual and both instrumental tests were running). According to plant
personnel, the plant was operating under normal conditions during the tests.
The average asphalt concrete production rates during the four test runs were 171, 276,
240, and 185 tph, respectively, corresponding to total production of 735, 1,187, 840, and
778 tons. During the first three test runs (August 19 and August 20), a surface asphalt coating
that included RAP was produced. During the fourth test run (August 21), a surface coating
(accounting for 75 % of the total asphalt concrete produced) and a binder coating (accounting for
25 % of total production) were produced, both without RAP. Recycled No. 2 fuel oil was used
for fuel in the production process during the tests. Conditioner was used during the four test runs
at a rate of 0.25 % of the asphalt cement used, for a total of 186, 302, 220, and 200 pounds,
respectively, during the four test runs.
Table 3.1 summarizes the operating conditions observed during the EPA source test
periods at Asphalt Plant "A". Tables 3.2 and 3.3 describe the asphalt mixes produced and the
fuel used, respectively, during the tests. Table 3.4 describes the specifics of plant operation
during the tests. Appendix A shows all the data recorded during the tests, along with the results
of statistical analyses.

4.0 SAMPLING LOCATIONS
Isokinetic sampling runs were attempted at both the baghouse inlet and outlet sampling
locations, but sampling was canceled at the baghouse inlet at the direction of the EPA WAM.
Detailed descriptions of the sampling locations and traverse point layouts follow.
4.1 BAGHOUSE INLET SAMPLING LOCATION
The baghouse inlet location consisted of a 48-1/2-inch diameter round duct which
connected the outlet of the drier to the baghouse. A schematic diagram of the inlet sampling
location is presented in Figure 4.1. The duct exited the drier vertically, made a 90° bend for the
run over to the baghouse, and made a second 90° bend prior to running down into the baghouse.
In order to enable for the extraction of gas samples at the baghouse inlet, plant personnel
installed two four-inch sample ports 25 inches upstream of the entrance to the baghouse. The
nearest upstream disturbance to the sample port was a downward turning elbow, which was
located 28 inches (0.58 diameters) from the sample ports. The nearest disturbance downstream
of the sample ports was the entrance into the baghouse, which was located 25 inches (0.52
diameters) from the sample ports. Based upon the criteria outlined in Method 1, this sample
location was not suitable for isokinetic source sampling. However, after consultation with EPA
EMC and EPA ESD personnel, the location was selected because an alternate location with
better stack geometry did not exist.
To conduct isokinetic sampling at this location, PES selected the maximum number of
sample points for particulate traverses as specified in Method 1, which was 24. The 24-point
sampling matrix (which is presented in Figure 4.2) consisted of two twelve-point sample
traverses on diameters offset 90° to each other. Prior to the initiation of isokinetic sampling
activities at this location, a cyclonic flow check using a Type-S pitot tube was conducted. The
results of the cyclonic flow check indicated an average rotation angle from null (a) of 7.2°.
Since this angle was less than 20° as specified in Method 1, the sampling location was
considered acceptable for isokinetic sampling without modification to the duct or the sampling
method.
4.2 BAGHOUSE OUTLET SAMPLING LOCATION
The baghouse outlet sampling location consisted of a square stack attached to the
opposite end of the baghouse from the inlet duct. The stack was 49-3/4 inches deep by 33 inches
wide, and the equivalent duct diameter was 39.7 inches. Six sample ports were located in the
4-1
-------
49-3/4 inch wall. The nearest downstream disturbance from the sample ports was the stack exit,
which was located 24 inches (0.60 equivalent duct diameters) from the sample ports. The nearest
upstream disturbance to the sample ports was the baghouse ID fan, which was located 88 inches
(2.2 equivalent duct diameters) from the sample ports. For this sample location, the minimum
number of sample points specified by Method 1 was 24. Accordingly, PES used a 24-point
sampling matrix consisting of six four-point sample traverses. Figure 4.3 presents a schematic
diagram of the baghouse outlet sampling location. Figure 4.4 presents the baghouse outlet
sample traverse point locations.

5.0 SAMPLING AND ANALYSIS PROCEDURES
Table 5.1 summarizes the sampling locations, test parameters, test methods, number of
tests, and net run time of each test event. Brief descriptions of each method follow:
5.1 LOCATION OF MEASUREMENT SITES AND SAMPLE/VELOCITY
TRAVERSE POINTS
EPA Method 1, "Sample and Velocity Traverses for Stationary Sources," was used to
select the measurement site at the baghouse outlet, and as a guideline for the selection of the
measurement site at the baghouse inlet. The cyclonic flow check procedure outlined in Method 1
was used to evaluate the suitability of the inlet location for isokinetic sampling. The sample
traverse locations at both the inlet and the outlet sampling locations were determined using
Method 1 procedures. The measurement sites are discussed in Section 4.0.
5.2 DETERMINATION OF STACK GAS VOLUMETRIC FLOW RATE
EPA Method 2, "Determination of Stack Gas Velocity and Volumetric Flow Rate (Type S
Pitot Tube)," was used to determine gas volumetric flow rate at the baghouse inlet and outlet. A
Type S pitot tube, constructed according to Method 2 criteria and having an assigned coefficient
of 0.84, was connected to an inclined-vertical manometer and used to measure velocity pressure.
A Type K thermocouple attached directly to the pitot tube was used to measure gas temperature.
For each sampling run, the gas velocity was calculated from the average of the square roots of the
velocity pressure readings, the average gas temperature, the molecular weight, and the stack static
pressure. The volumetric flow rate was calculated as the product of the average gas velocity and
the duct cross-sectional area.
5.3 DETERMINATION OF DRY MOLECULAR WEIGHT AND EMISSION
CORRECTION FACTORS
EPA Method 3B, "Gas Analysis for the Determination of Emission Rate Correction
Factor or Excess Air," was used to measure CO2 and O2 content of the stack gases. Gas samples
were extracted from the baghouse outlet using the integrated, single-point bag sampling
technique. The bag contents were analyzed onsite within four hours after sample collection using
an Orsat® analyzer to determine concentrations of CO2 and O2. The Orsat® analyzer used for gas
analysis had 0.2 % subdivisions.

5.4 DETERMINATION OF STACK GAS MOISTURE CONTENT
EPA Method 4, "Determination of Moisture Content in Stack Gases," was used to
determine gas moisture content. The quantity of condensate collected during each sampling run
was determined gravimetrically as the difference of the pre- and post-test impinger weights. The
gas moisture volume was then calculated as the ratio of the moisture volume (assuming a
conversion factor of 0.0415 grams per cubic foot) to the sum of the moisture volume and the dry
gas volume as indicated by the dry gas meter. The Method 4 procedure was conducted
simultaneously with each Method 23 and Method 29 sampling run.
5.5 DETERMINATION OF POLYCHLORINATED DIBENZO-P-DIOXINS AND
POLYCHLORINATED DIBENZOFURANS
EPA Method 23, "Determination of Polychlorinated Dibenzo-p-Dioxins and
Polychlorinated Dibenzofurans From Stationary Sources" was used to determine PCDDs and
PCDFs at the baghouse inlet and outlet. A schematic of the Method 23 sampling train is shown
in Figure 5.1. Gas samples were extracted from the gas streams isokinetically, and passed
through a glass nozzle, heated glass-lined sample probe, a heated glass fiber filter, a coil

condenser, and a sorbent resin trap containing approximately 40 grams of spiked XAD®-2
sorbent resin. Ice water from the impinger bath was continuously recirculated through water
jackets on the coil condenser and the XAD®-2 sorbent resin trap to cool the sample gas and
facilitate absorption of PCDDs and PCDFs onto the XAD®-2 resin. At the conclusion of each
sample run, the sample train components (except the sorbent trap) were rinsed the with pesticide-
grade acetone, methylene chloride, and toluene.
Upon receipt by the subcontract laboratory, TLI, the samples were concentrated
combined, and analyzed using a GC/MS. Sample aliquots were initially separated using a DB-5
capillary column. In cases where the results of the analyses using the DB-5 column indicated the
presence of 2378 PCDFs; the sample was re-analyzed using a DB-225 capillary column, and the
results of the DB-225 analysis were used for .the subsequent calculations of emission rate and
toxic equivalency for the 2378 PCDFs congener.
5.6 DETERMINATION OF PARTICULATE MATTER AND METALS
EPA Method 29, "Determination of Metals Emissions From Stationary Sources," was
used to determine filterable PM and metals at the baghouse inlet and baghouse outlet locations.
The target metals included: Antimony (Sb), Arsenic (As), Barium (Ba), Beryllium (Be),
Cadmium (Cd), Chromium (Cr), Cobalt (Co), Copper (Cu), Lead (Pb), Manganese (Mn),
Mercury (Hg), Nickel (Ni), Phosphorus (P), Silver (Ag), Selenium (Se), Thallium (Tl), and Zinc
(Zn). A Method 29 sampling train schematic is presented in Figure 5.2.
Gas samples were withdrawn from the gas streams isokinetically and through a glass
nozzle, heated glass-lined sample probe, a heated quartz fiber filter, and an impinger train
containing reagents for the absorption of metals. The first impinger in the train was empty, the
second and third impingers each contained 100 milliliters (ml) of a 5 % nitric acid (HNO3)/10 %
hydrogen peroxide (H2O2) solution, the fourth impinger was empty, the fifth and sixth impingers
each contained 100 ml of a 4 % potassium permanganate (KMnO4)/10 % sulfuric acid (H2SO4)
solution, and the last impinger contained a known quantity of silica gel.
The sample recovery scheme for metals is shown in Figures 5.3 and 5.4. At the
conclusion of each sampling run, the front half of the sampling train (i.e., in front of the tared
quartz fiber filter) was rinsed with acetone followed by a solution of 0.1 N HNO3. The first three
impingers were quantitatively recovered and rinsed with 100 ml of HNO3 solution; the impinger
contents and the rinses were collected in a pre-cleaned glass sample bottle. The contents of the
fourth and fifth impingers were recovered and impingers rinsed with 100 ml of fresh acidified
potassium permanganate solution, followed by a rinse with 100 ml of deionized water into a pre-
cleaned glass sample bottle. The fourth and fifth impingers were then rinsed with 25 ml of 8 N
HCL solution, which was collected in pre-cleaned glass sample jar containing 200 ml of
deionized water.
Analyses for the determination of PM concentrations and emission rates were conducted
at PES' facilities in Research Triangle Park, NC. The acetone and nitric acid probe rinses and
the filters were transferred to pre-cleaned, tared beakers, evaporated to dryness, desiccated, and
5-4
-------
weighed to constant weight. At the conclusion of the PM analysis, the beakers were sealed with
Parafilm™ and transported to the subcontract laboratory, TLI, for determination of the target
metals content. Each sample run generated two fractions for the analysis of all target metals
except mercury, and five fractions for analysis of mercury. Analysis for the target metals was
conducted according to the sample analysis scheme presented in Figures 5.3 and 5.4. Except for
mercury, analyses of the target metals were conducted using the analytical method which resulted
in the lowest detection for each metal; either graphite furnace atomic absorption spectroscopy
(GFAAS), or inductively coupled argon plasma (ICP) emission spectroscopy. Analysis for
mercury content was determined using cold vapor atomic absorption spectroscopy (CVAAS).
5.7 DETERMINATION OF PLUME OPACITY
EPA Method 9, "Visual Determination of the Opacity of Emissions from Stationary
Sources" was used to quantify visible emissions from the baghouse outlet stack. DEECO, PES'
subcontractor, provided a certified VEO. The observer was certified to read plume opacities at a
field training session held in Raleigh, North Carolina by Eastern Technical Associates of
Raleigh, North Carolina on March 12, 1997 (Certificate No. 257158).

6.0 QUALITY ASSURANCE/QUALITY CONTROL
PROCEDURES AND RESULTS
This section describes the specific QA/QC procedures employed by PES during the
performance of this source testing program. PES' quality assurance program was based
upon the procedures and guidelines contained in the "Quality Assurance Handbook for Air
Pollution Measurement Systems, Volume III, Stationary Source Specific Methods,"
EPA/600/R-94/038c, as well as in the test methods to ensure the collection, analysis,
and reporting of reliable source test data.
6.1 CALIBRATION OF APPARATUS
Since no mechanism exists for an independent measurement of emissions from the
source, careful preparation, checkout, and calibration of the source testing sampling and
analysis equipment is essential to ensure the collection of data of high quality. PES maintains
a comprehensive schedule for preventative maintenance, calibration, and preparation of the
source testing equipment.
6.1.1 Barometers
PES used aneroid barometers which were calibrated against a station pressure value
reported by a nearby National Weather Service Station, and corrected for elevation.
6.1.2 Temperature Sensors
The responses of the Type K thermocouples used in the field testing program were
checked using Calibration Procedure 2e as described in the Quality Assurance Handbook. The
response of each temperature sensor was recorded when immersed hi an ice water bath, at
ambient temperature, and in a boiling water bath; each response was checked against an ASTM
3F reference thermometer. Table 6.1 summarizes the results of the thermocouple checks and
the acceptable levels of variance. Digital temperature readouts were checked for calibration
using a thermocouple simulator having a range of 0-2400 °F.
6.1.3 Pilot Tubes
For the measurement of velocity pressure in the gas streams, PES used Type S pitot
tubes constructed according to EPA Method 2 specifications. Pitot tubes meeting these
geometric specifications are assigned a baseline pitot coefficient (Cp) of 0.84 and need not be

subjected to a wind tunnel calibration. PES performs, at a minimum, annual calibration checks
of pitots using Calibration Procedure 2 as found in the Quality Assurance Handbook. The
results of the dimensional checks for each pitot tube used in this test program are summarized
in Table 6.2.
6.1.4 Differential Pressure Gauges
PES uses Dwyer inclined/vertical manometers to measure differential pressures. These
include velocity pressure, static pressure, and meter orifice pressure. Manometers are selected
with sufficient sensitivity to accurately measure pressures over the entire range of expected
values. Manometers are primary standards and require no calibration.
6.1.5 Dry Gas Meter and Orifice
The Method 23 and 29 dry gas meters and orifices were calibrated in accordance with
Calibration Procedure 5 in the Quality Assurance Handbook. This procedure involves direct
comparison of the dry gas meter to a reference dry test meter. The reference dry test meter is
calibrated annually against a wet test meter. Before its initial use in the field, the metering
system was calibrated at several flow rates over the normal operating range of the metering
system. For the initial calibration to be considered valid, the results of individual meter
calibration factors (y), cannot differ from the average by more than 0.02, and the results of
individual meter orifice factors (AH@), cannot differ from the average by more that 0.20.
After field use, the metering system calibration was checked at the average flow rate and
highest vacuum observed during the test period. The results of the post-test meter correction
factor check cannot differ by more that 5 % from the average meter correction factor obtained
during the initial, or thereafter, the annual calibration. Table 6.3 presents the results of the
dry gas meter and orifice calibrations. All dry gas meters and orifices used in this test
program met the method calibration requirements.
6.2 ON-SITE MEASUREMENTS
The on-site QA/QC activities include:
6.2.1 Measurement Sites
Prior to sampling, the stack was checked dimensionally to determine the suitability of
the measurement site locations with respect to the Method 1 criteria. Distances to upstream
and downstream disturbances, test port locations, and inside stack dimensions were checked to
evaluate the uniformity of the stack cross sectional area. The inside stack dimensions, stack
wall thickness, and sample port lengths were measured to the nearest 0.1 inch.

6.2.3 Flue Gas Sampling
Integrated flue gas samples were collected in Tedlar® gas bags from the baghouse
exhaust. Prior to their initial use, the bags were leak checked and purged with nitrogen to ensure
cleanliness. Prior to and after completion of each sampling run, the stack gas molecular weight
sampling system was leak checked. The bag samples were analyzed on-site using an Orsat®
analyzer. Prior to use the Orsat® analyzer was assembled and replenished with fresh reagents and
leak checked as per the manufacturer's procedures.
6.2.4 Moisture
During sampling, the exit gas temperature of the last impinger in each sampling train was
maintained below 68°F to ensure condensation of stack gas water vapor. The moisture gain in
the impinger train due to flue gas moisture was determined gravimetrically using a digital top-
loading electronic balance with a resolution of 0.1 g. For subsequent calculations of the flue gas
moisture volume, the calculated moisture volume due to the impinger weight gain was compared
to the stack gas saturation volume at the average stack gas temperature. If the calculated
moisture volume due to impinger weight gain exceeds the saturation volume, the assumption is
made that moisture droplets entered to sampling system, and the saturation volume is used to
6-5
-------
calculate stack gas molecular weight. The lower moisture value obtained using the reference
method and saturation method was subsequently used in all Method 23 and Method 29
calculations.
6.2.5 Method 23/Method 29
The QA/QC activities for the for Method 23 and Method 29 sampling trains were similar.
Prior to field testing, all glassware used was pre-cleaned according to the guidelines presented in
Methods 23 and 29. The Method 23 glassware was cleaned based upon procedures presented in
Section 3 A of "The Manual of Analytical Methods for the Analysis of Pesticides in Human and
Environmental Samples." The Method 29 sampling train glassware was prepared by first rinsing
with hot tap and then water and then washed in hot soapy water. Next, all glassware was rinsed
three times with tap water, followed by three additional rinses with water. Then all glassware
was soaked in a 10 percent (V/V) nitric acid solution for a minimum of 4 hours, rinsed three
times with water, then rinsed a final time with acetone, and allowed to air dry. On all of the
Method 23 and Method 29 glassware, openings where contamination could occur were covered
with Parafilm™ or Teflon® tape until the trains were assembled for sampling.
Table 6.4 summarizes the results of the post-test sample train leak checks for the
Method 23 and Method 29 sampling trains, as well as the isokinetic sampling ratios for each of
the sampling runs attempted. It should be noted that the Method 23 and Method 29 sampling
runs at the baghouse inlet were aborted after approximately 20 minutes of sampling. Although
the Method 29 isokinetic sampling ratio was within the required tolerance, the Method 23 ratio
was not. This was due to the significant pressure drop across the train from the collected
paniculate matter and the XAD®-2 sorbent resin trap, which made it impossible to collect a gas at
the flow rate required by the isokinetic rate equation. All pre- and post-test sample train leak
checks met the acceptance criteria.
In order to evaluate the effectiveness of the on-site cleanup procedures, field blank
samples of the Method 23 and Method 29 sample trains were collected during the field test
program. The sample trains were assembled in same manner as the trains prepared for actual
sampling runs and were transported to the baghouse outlet sampling location. The sample trains
were each leak-checked and allowed to heat to the normal operating temperature. They were
then leak-checked again and transported to the on-site field laboratory for recovery. The samples
generated from the field blank trains were handled and analyzed in the same manner as the other
samples generated during actual test runs.
In order to evaluate contamination levels in the sampling reagents, blank samples of all
reagents used for both the Method 23 and Method 29 sampling were collected. These sample
blanks were submitted for analysis along with the run samples and field blank samples for
analysis.

6.3 ANALYSES
Table 6.5 presents the results of the recoveries of the internal standards in the
PCDDs/PCDFs samples. The recoveries for run S-M23-O-4 are elevated because an insufficient
amount of recovery standard was added to the sample. Due to the nature of the error, the
measured amounts of PCDDs/PCDFs congeners in the sample are not biased. Analysis of
method, field, and reagent blanks showed background levels of the congeners less that the target
detection limits for each congener.
The results of QA/QC analyses for Method 29 are presented in Tables 6.6 through 6.13.
Table 6.6 presents the results of the TLI Lab Control Spike. All lab control spike recoveries
were within 10 percent of the spiked amount. The post digestion matrix spike (Table 6.7)
indicated recoveries outside of the QC criteria (75%-125%) for Ag, Be, P, Pb, and Se on the
front-half spikes, and As, and Mn, on the back-half spikes. The results of the spikes indicate
matrix effects specific to these analytes in the native sample matrix. The results of the duplicate
analysis performed are presented in Table 6.8. A duplicate analysis is not reported for Tl since
graphite furnace atomic absorption (GFAA) was used after analysis by inductively coupled
plasma emission spectroscopy (ICP) indicated high negative values. The GFAA apparatus takes
two separate aliquots sample of the and averages the result. The ICP takes a continuous aliquot,
performs three analyses, and averages the result. Since the analysis for most of the target metals
was less than 10 times the reporting detection limit (RDL), the duplicate analysis should not be
considered a valid qualifier for those analytes. These cases are noted as "

16 ABSTRACT
The United States Environmental Protection Agency (EPA) is investigates the asphalt concrete production source category to identify and quantify
emissions of hazardous air pollutants (EIAPs) from rotary aggregate dryers There are two types of rotary drum dryers in use at asphalt concrete
production plants, parallel flow, wherein the direction of travel of the drying aggregate is in the same direction of travel of the the burner exhaust gases.
and counter flow, wherein the aggregate and exhaust gas flows are opposite :: each other Plant "A" , Clayton, North Carolina was identified and
selected b\ EPA as the host facility at which to obtain data on air emissions ;"-crn a counter flow continuous drum mix process that utilized a baghouse
for control of air emissions
The priman objective of the testing program was to obtain data on conro ,ej and uncontrolled emissions of polychlormated dibenzo-p -dioxins
(PCDDs or "dioxms") and polychlorinated dibenzofurans (PCDFs or "furans i paniculate matter (PM) and metallic HAP and non-HAP compounds
Testing of uncontrolled emissions was deleted from the scope of work because :ne high paniculate gram loading at the inlet to the baghouse exceeded
the sampling capacity of the Method 23 and Method 29 sampling trains A 5c;;"idar> objective was to observe and record plume opacity form the
baghouse The data will be used by the EPA's Emission Standards Diusion ;-• Determine \\hetherHAPs are emitted at levels that would ]ustif>
regulation under the Maximum Achievable Control Technolog> (MACI) rr;g-.vr,
Dunns the testme program another EPA contractor monitored and recorcec process and emission control system operating parameters, and
prepared Section 3 0, Process Description, of this report
This \olume (Volume I) is comprised of 166 pages and consists of the repcr. text and Appendices A (Process Data) and B (Raw Field Data)
