Abstract
Non-Methane Organic Compound (NMOC) and Speciated Non-Methane (SNMOC)
sample collection systems were used to collect ambient air in eight areas from June through
September where the National Ambient Air Quality Standards (NAAQS) for ozone may be
exceeded. The program to collect and analyze ambient air samples was conducted by Radian
Corporation in support of the U.S. Environmental Protection Agency, Office of Air quality
Planning and Standards (EPA/OAQPS). The NMOC and SNMOC program generally consists of
several activities that include site coordination, equipment certification, installation; sample
analysis, data reduction, validation, and reporting; statistical analyses and data characterization;
and formatting and submittal of the validated data to the Aerometnc Information Retrieval System
(AIRS). Non-methane hydrocarbons are reported for the base NMOC program. Seventy-eight
compounds were targeted for the speciated NMOC base program and the speciated option to the
NMOC base program; thirty-eight compounds were targeted for the toxics option, and sixteen
compounds were targeted for the carbonyls option. Statistical analysis includes number of
occurrences, frequency percent, maximum, minimum, median, and mean concentrations.
Standard deviation, skewness, and kurtosis are reported for the speciated, toxics, and carbonyl
options. Sites in Long Island, New York, Newark and Plainfield, New Jersey, Birmingham,
Alabama, and Fort Worth and El Paso, Texas, participated in the various programs and options.

1.0 BACKGROUND AND INTRODUCTION
In certain areas of the country where the National Ambient Air Quality Standard
(NAAQS) for ozone may be exceeded, additional measurements of ambient non-methane organic
compounds (NMOC) and nitrogen oxides (NOJ are used to assist the affected states in
developing revised ozone control strategies. Measurements of NMOC are a critical input to the
Empirical Kinetic Modeling Approach (EKMA) used to estimate hydrocarbon control
requirements. Due to previous difficulty in obtaining accurate NMOC measurements, and in
order to transfer hydrocarbon sampling and analysis technology to interested state and local
650-OOB-03-07/cah 1-1
-------
agencies, the United States Environmental Protection Agency (EPA) has supported a centralized
program that provides NMOC monitoring and analytical assistance to these state and local
agencies through Radian Corporation. This program originated in 1984 with NMOC program
support to 23 sites.
In order to support the needs for information concerning the levels of toxic species in
ambient air, a gas chromatography/multiple detector (GC/MD) method was developed in 1987 to
measure the concentration of 38 selected toxic organic compounds in canister samples collected
over a 24-hour period. The method was originally developed for use on the EPA national Urban
Air Toxics Monitoring Program (UATMP). The UATMP was developed and implemented in
1987 following an EPA study entitled "The Air Toxic Problem in the United States: An Analysis
of Cancer Risks for Selected Pollutants,"1 which was completed in May 1985. This study
concluded that a high potential of elevated individual lifetime risks was associated with certain air
toxic compounds frequently found in urban areas. The UATMP method was incorporated into
the 1987 NMOC program as an option to the NMOC base sites. Selected NMOC samples from
15 sites were analyzed in 1987 for the 38 UATMP target analytes. Additionally, in 1990 carbonyl
monitoring and analysis was added to the NMOC program at three sites for the measurement of
formaldehyde, acetaldehyde, and acetone in 3-hour carbonyl cartridges. In 1991, the carbonyl
target analyte list was revised to encompass 16 compounds.
Also in 1991, some of the agencies participating in the NMOC program requested that
hydrocarbon speciation analysis be included as part of the program. Knowledge of the specific
individual hydrocarbon compounds present in the ambient air is used for photochemical model
input, such as Carbon Bond Four (CB4), necessary for forecasting the NMOC reductions needed
to attain the NAAQS for ozone. Consequently, in response to the agency requests, gas
chromatography with flame ionization detection (GC/FID) analysis for 78 individual hydrocarbon
compounds in the C2 through C,2 range was provided for five sites and referred to as Speciated
NMOC.
The sampling sites for the 1994 NMOC and Speciated NMOC monitoring program are
given in Table 1-1. Table 1-1 includes the EPA Region for each site, the number of sites at each

location, the Radian site code, the Aerometric Information Retrieval System (AIRS) code, site
location, and the base and optional program participation for each site. The AIRS site description
detailing the site characteristics are given in Appendix A. There were three NMOC base sites
located in Long Island, NY (LINY), Newark, NJ (NWNJ), and Plainfield, NJ (PLNJ). The LINY
site has been participating in the NMOC program since 1990; the NWNJ site since 1987; and the
PLNJ site since 1988. All three sites chose the Speciated NMOC analysis option, and two sites
(NWNJ and PLNJ) chose 3-hour toxics and carbonyl analysis options. There were five Speciated
NMOC base sites located in Birmingham, AL (B1AL, B2AL, and B3AL), Fort Worth, TX
(FWTX), and El Paso, TX (EPTX). All five sites have been participating in the Speciated NMOC
program since 1992, with the exception of EPTX which started in 1991. Three of these sites
(B1AL, B2AL, and B3AL) chose the 3-hour toxics analysis option.
The NMOC and Speciated NMOC program generally consists of several activities that
include:
• Site coordination;
• Equipment certification, installation, and operator training;
• Sample analysis;
• Data reduction, validation, and reporting;
• Statistical analyses and data characterization;
• Formatting and submittal of the validated data to the AIRS-AQS; and
• Post-sample collection activities, such as equipment recovery and refurbishment,
and canister cleanup and archive.
The NMOC and Speciated NMOC program sample collection systems and procedures are
identical. Both Toxics and Speciated NMOC option analyses are performed as subsequent
analyses on a single sample canister. Carbonyl option samples are collected on the same schedule
using a separate cartridge sample collection system.

Sample collection for the 1994 NMOC base program occurred from 6:00 a.m. through
9:00 a.m. local time, Monday through Friday, from July 6 through October 31, 1994 for the
NMOC base sites. Sample collection for the 1994 Speciated NMOC base program occurred from
6:00 a.m. through 9:00 a.m. local time, Monday through Friday, from July 5 through October 31,
1994. Historically, the NMOC and Speciated NMOC sampling season has begun in June and
ended in September, encompassing approximately 90 sampling days. In 1994, the sites started
sampling in July and continued through October 31, for a total of about 81 sampling days. The
Birmingham, AL, (BIAL, B2AL, B3AL) began sampling July 5, and the Ft. Worth (FWTX) and
El Paso, TX, (EPTX) sites began sampling July 8. The Long Island, NY, site (LINY) began
sampling July 6, and the Plainfield and Newark, NJ sites (PLNJ and NWNJ) began sampling
July 11. The LINY, PLNJ, and NWNJ sites did not sample during the Labor Day Holiday
(September 5) and PLNJ and NWNJ did not sample during the Columbus Day Holiday
(October 10).
Sample analyses were performed in accordance with the cryogenic preconcentration direct
flame ionization detection (PDFID) methodology described in compendium method TO-12.2
Based on the 1984 through 1992 studies, the method was shown to be precise, accurate, and
effective for indicating the concentration level of total hydrocarbons in ambient air. Sample
analyses were performed generally in accordance with the EPA's "Research Protocol Method for
Analysis of C2 Through C12 Hydrocarbons in Ambient Air by Gas Chromatography with
Cryogenic Concentration."3 Seventy-eight hydrocarbons are quantitated during this analysis.
Chlorinated and oxygenated species are not identified using this procedure.

2.0 SUMMARY OF RESULTS
This section of the report contains summary information on the various base programs
and options. Concentration results from all sites are summarized and the data is characterized and
analyzed. Sampling and analytical precisions, accuracy, completeness, frequency of occurrence,
and historical comparisons for each of the programs have been determined and results are
presented (including the results of external audits and comparison samples). Information on the
entry of site data into the AIRS-AQS database is provided as well. For more detailed information
on each of the base and option program features, refer to Chapters 5.0 through 8.0 of this report.
2.1 Summary of Concentration Results by Program
This summary section contains information on the results of the NMOC and Speciated
NMOC base programs, as well as on the carbonyl, speciated NMOC, and toxics options to these
base programs. The information compiled for all sites is used to make annual overall comparisons
of the mean data from previous years.
2.1.1 NMOC Base Program
The three sites involved in this program were Long Island, NY (LINY), Newark, NJ
(NWNJ), and Plainfield, NJ (PLNJ). LINY has been involved in the NMOC program since 1990,
NWNJ has been involved since 1987, and PLNJ since 1988. Results by site are included in
Appendix B.
A summary of the NMOC overall site results is contained in Table 2-1. Detected
NMOC levels ranged from 0.06 ppmC to 2.52 ppmC. Overall, PLNJ was found to have the
highest mean ambient concentration level of NMOC (0.66 ppmC), followed by NWNJ
(0.64 ppmC) and LINY (0.45 ppmC). Maximum concentrations were found to also follow this

trend: PLNJ, 2.52 ppmC; NWNJ, 2.51 ppmC; LINY, 1.46 ppmC. The standard deviations
indicate that the data were much more variable at PLNJ (a- 0.539) than they were at NWNJ
(<7= 0.397) and LINY (a= 0.292).
2.1.2 Speciated NMOC Option to the NMOC Base Program
All three of the NMOC base sites (LINY, NWNJ, and PLNJ) elected to participate in
the speciated NMOC option and had nine, nine, and eight of their NMOC samples speciated,
respectively. The 26 samples were analyzed and the summary data are contained in Table 2-2.
Results by site are included in Appendix C.
For the three sites the overall detected average concentrations ranged from a low of
0.33 ppbC for w-tridecane, to a high of 35.00 ppbC for toluene. The highest level of a target
compound encountered was 229.05 ppbC for acetylene at PLNJ. This sample was taken on
September 21, 1994 and also contained the highest levels of 1,3-butadiene, 2-methyl-1-pentene,
propyne, and toluene detected at any of the three sites.

2.1.3 Carbonyl Option to the NMOC Base Program
Two of the NMOC base sites chose the carbonyl option: Newark, NJ (NWNJ) and
Plainfield, NJ (PLNJ). Results of the studies are contained in Tables 2-3 and 2-4. Tolualdehydes
comprise meta-, para-, and ortho-tolualdehyde. Because these three components cannot be
speciated on the analytical system, tolualdehydes are reported as one compound.
For NWNJ, the mean concentrations of the carbonyl compounds ranged from 0.14 ppbv
for valeraldehyde to 7.64 ppbv for formaldehyde. The highest level of any carbonyl compound
detected was 38.22 ppbv for formaldehyde at NWNJ. This level was detected in the sample taken
September 20, 1994. This one sample also contained the highest recorded site levels of eight
other carbonyls: acetaldehyde, propionaldehyde, crotonaldehyde, butyr/isobutyraldehyde,
benzaldehyde, tolualdehydes, hexanaldehyde, and 2,5-dimethylbenzaldehyde. No reason for these
high levels was identified. The high standard deviation shown for formaldehyde in Table 2-3
indicates the large variability in this individual component of the data set. High speciated
hydrocarbons were also recorded on September 21, 1994.
For PLNJ, the mean values ranged from 0.27 ppbv for hexanaldehyde to 5.28 ppbv for
acetone. An anomalously high level of 27.24 ppbv acetaldehyde was detected in the sample taken
September 16, 1994. None of the other species identified in this sample were present at unusually
high concentrations and no reason for the high acetaldehyde level is known. The data was
verified and the result was found to be valid.
Typical urban ambient levels range from 1.8 to 15.5 ppbv for formaldehyde and 1.0 to
8.5 ppbv for acetaldehyde.4 The mean levels observed at NWNJ and PLNJ fall within these
ranges.
2.1.4 Speciated NMOC Base Program
Five Speciated NMOC base sites participated in the 1994 program. Three of these sites
were located in Birmingham, AL (Bl AL, B2AL, and B3AL), one in Ft. Worth, TX (FWTX), and

one in El Paso, TX (EPTX). The three Birmingham sites and FWTX have all been involved in the
Speciated NMOC program since 1992. EPTX joined the program in 1991.
A summary of the Speciated NMOC overall site results is contained in Table 2-5. Due
to its large volume, one copy of the speciated NMOC base program summary data by site has
been provided to the EPA/OAQPS project officer. Overall average concentrations ranged from a
low of 0.46 ppbC for 1-tridecene, to a high of 28.72 ppbC for isopentane. The highest level of a
target compound encountered was 3370.75 ppbC for w-hexane at EPTX on September 14, 1994.
This same sample also contained the highest recorded levels of 11 other species: 1-pentene,
2,3-dimethylbutane, 2,4-dimethylpentane, 2-methylpentane, 3-methylpentane, cyclohexane,
cyclopentane, isobutane, isopentane, methylcyclopentane, and n-pentane. Due to the extremely
anomalous nature of this data, the value and sample integrity was reverified and no known cause
was identified.
2.1.5 Toxics Option to the NMOC and Speciated NMOC Base Program
Two NMOC base sites (NWNJ and PLNJ) and three Speciated NMOC base sites
(B1AL, B2AL, and B3AL) chose to include the toxics option in their monitoring programs. A
summary of the toxics option overall site results is contained in Table 2-6. A total of 38
compounds were targeted. Results of the toxics option by site appears in Appendix D.
Average concentrations ranged from 0.01 ppbv for 1,1-dichloroethane, to 13.16 ppbv
for acetylene. The highest level encountered was 197.78 ppbv for acetylene at PLNJ. This
sample was taken on September 21, 1994, which is the same sample that high levels of acetylene
were identified in the Speciated NMOC analysis (see Section 2.1.3). This sample also contained
the highest levels of chloroform and chlorobenzene detected overall at the toxics option sites. No
cause for these high levels was identified.

2.2 Data Characterization and Analysis
This section contains information pertaining to how the data collected in the 1994
NMOC and Speciated NMOC Programs and their options was characterized and analyzed. The
frequency of occurrence for each of the compounds speciated in the NMOC base program and the
Speciated NMOC, carbonyl, and toxics option programs is provided. Information on the monthly
results from the NMOC program, and how the 1994 program compares with previous years is
contained in this section. Historical information from each of the sites involved in the 1994
programs is provided.
2.2.1 Frequency of Occurrence
The following sections summarize the frequencies that speciated compounds were
detected during the respective programs or options in 1994.
2.2.1.1 Speciated NMOC Option to the NMOC Base Program
A total of 26 samples from the three NMOC base sites (LINY, NWNJ, and PLNJ) were
speciated. The number of occurrences of each compound and frequency percent data for this
option are contained in the first three columns of Table 2-2.
For the three sites, the overall frequency percent of detection of the 78 target
compounds ranged from 3.9% for 2-ethyl-l-butene and isobutene, to 100% for 38 different
compounds. The compounds detected in all samples compared with those detected in none of the
samples are outlined by site in Table 2-7. Table 2-8 shows the frequencies of detection for each
compound broken down into frequency categories: 0-25% (3), 25-50% (2), 50-75% (8), 75-90%
(11), and 90-100 percent (53).

2.2.1.2 Carbonyl Option to the NMOC Base Program
Ten carbonyl sample cartridges from NWNJ, including two duplicate pairs, and eleven
from PLNJ, including one duplicate pair, were selected for sample analysis. Samples were
collected concurrently with the NMOC canister sample through the use of a separate sampling
and control system. Sixteen carbonyl compounds were targeted for analysis.
Tables 2-3 and 2-4 contain summary data for NWNJ and PLNJ, respectively. The
frequencies of occurrence of the 16 carbonyl compounds targeted for analysis ranged from 0% to
100% for both sites. Because the meta, para, and ortho components cannot be separated on the
analytical system, tolualdehydes are reported as one compound. One compound,
isovaleraldehyde, was not detected in any samples from either site. Formaldehyde, acetaldehyde,
acetone, propionaldehyde, and butyr/isobutyraldehyde were found in 100% of all samples from
both sites. Tolualdehydes were detected at very low levels in all samples from NWNJ, but in no
samples from PLNJ. Aldehydes are ubiquitous in urban air, where they are emitted by a variety of
mobile and stationary sources. In addition, formaldehyde and acetaldehyde, the two most
abundant species, are formed in situ by the oxidation of virtually all hydrocarbons.
2.2.1.3 Speciated NMOC Base Program
Summary data for all five Speciated NMOC base sites (B1AL, B2AL, B3AL, FWTX,
and EPTX) are contained in Table 2-5. The first three columns indicate the compound, the
number of occurrences in which the compound was detected (out of 394 analyses), and the
frequency percent. Duplicate and duplicate/replicate data for a given sample date were averaged
and considered as one sample. A total of 439 samples were collected, including 45 duplicate
samples. Seventy-eight hydrocarbons were quantified during analysis.
The overall frequency percent of detection of the 78 target compounds ranged from
1.02% (4 occurrences) for isobutene, to 99.75% (393 occurrences) for benzene, isobutane,
isopentane, propane, and toluene. None of the 78 target hydrocarbons was found to be
ubiquitous or entirely absent. Some of the 78 target hydrocarbons were present in 100% or 0%

of all samples from specific sites as indicated in Table 2-9. Table 2-10 outlines the frequencies of
occurrence for each compound broken down into frequency categories: 0-25% (6), 25-50% (5),
50-75% (12), 75-90% (20), and 90-100% (35).
2.2.1.4 Toxics Option to the NMOC and Speciated NMOC Base Program
The toxics option frequency of occurrence values for the 38 targeted compounds at the
five sites are summarized in the first three columns of Table 2-6. These indicate the number of
occurrences in which a given toxic was detected (out of 40 analyses), along with the frequency
percent. In cases where duplicate samples were taken, or replicate analyses were performed, the
results of all the analyses were averaged for each sample.
The frequency percent for the toxics ranged from 0% for chloroprene,
bromochloromethane, bromodichloromethane, c/5-l,3-dichloropropene, trans-1,3-
dichloropropene, 1,1,2-trichloroethane, and dibromochloromethane, to 100% for propylene,
chloromethane, methylene chloride, chloroform, 1,1,1-trichloroethane, benzene, carbon
tetrachloride, toluene, tetrachloroethylene, ethylbenzene, m- and/>-xylene, styrene, and o-xylene.
2.2.2 Historical Comparison Results and Discussion
Comparisons between the results of the 1994 program and previous years' programs at
each of the NMOC and Speciated NMOC base sites are given in the following sections. The
NMOC concentration is also compared by month to previous years. Speciated NMOC summary
data by site appear in Appendix E; the data were compared to previous years.

2.2.2.1 NMOC Monthly Variations
Table 2-11 partitions the NMOC data for the summer of 1994 into groups that
correspond to monthly intervals. For this time period, the monthly concentration means and
medians of the NMOC sites roughly parallel one another, the lone exception occurring in August.
The August value for the median decreases slightly from July, whereas the value of the mean
concentration has increased slightly from the July value. Entering into September, both median
and mean decrease from the August values. A noticeable increase in both median and mean is
observed for the month of October. Figure 2-1 shows a plot of these mean values and illustrates
how they compare with program results from previous years, dating to 1988.

The 1994 overall results are comparable with the overall results encountered in previous
years. Looking at Figure 2-1, few trends in the data are immediately apparent. Generally,
increases and decreases from month to month have occurred randomly, with approximately the
same number of increases as decreases. However, the mean of the plotted mean values shows a
slight decrease from June to July, a slight increase from July to August, a slight decrease from
August to September, and a slight increase from September to October. The 1994 data closely
parallel these values, with the exception of October 1994 which was the highest of the three

2.2.2.2 Birmingham, AL (B1AL)
Speciated NMOC data for B1AL were examined back to the inception of the program at
this site in 1992. Average frequencies of occurrence for the 78 target compounds increased
slightly in 1994: 1994, 83.4%; 1993, 75.7%; and 1992, 75.2%. In all cases, the frequencies of
occurrence for individual compounds ranged from 0% to 100%. Toluene, propane, and
isopentane were found to be among the most prevalent compounds and had the highest mean
concentrations. Both toluene and isopentane are indicative of mobile source emissions. The
highest mean concentrations were: 1994, 26.27 ppbC of isopentane; 1993, 23.60 ppbC of
isopentane; and 1992, 29.10 ppbC of isopentane. The highest observed concentrations were:
1994, 133.35 ppbC of propane; 1993, 140.50 ppbC of propane; and 1992, 163.33 ppbC of
isopentane. It is possible that the high levels of propane observed at this site are produced by the
flare stack of a major coke producing plant located about Vi mile west of the sampling location.
2.2.2.3 Birmingham, AL (B2AL)
Speciated NMOC data for B2AL were examined back to the inception of the program at
this site in 1992. Average frequencies of occurrence for the 78 target compounds increased in
1994: 1994, 68.0%; 1993, 59.0%; and 1992, 56.7 percent. In 1992 and 1993, the frequencies of
occurrence for individual compounds ranged from 0% to 100 percent. In 1994, the frequencies
ranged from 1.3% to 98.7% (present in one sample of 79 and missing in one sample,
respectively). Toluene and isopentane, both indicative of mobile source emissions, were found to
be among the most prevalent compounds and had the highest mean concentrations. In addition,
high levels of w-butane and w-pentane were present in 1992, high levels of w-undecane were
present in 1993, and high levels of propane and 1,2,4-trimethylbenzene were present in 1994.
Levels of these compounds in other years were not noticeably higher than those of other
compounds. The highest mean concentrations were: 1994, 9.04 ppbC of isopentane; 1993,
24.10 ppbC of isopentane; and 1992, 13.93 ppbC of isopentane. The highest observed
650-008-03-07/cah

-------
concentrations were: 1994,118.86 ppbC of isopentane; 1993, 668.20 ppbC of isopentane (the
standard deviation was also high, indicating large variability among the measured concentrations);
and 1992, 137.73 ppbC of isopentane.
2.2.2.4 Birmingham, AL (B3AL)
Speciated NMOC data for B3AL were examined back to the inception of the program at
this site in 1992. Average frequencies of occurrence for the 78 target compounds exhibited an
increasing trend: 1994, 69.3%; 1993, 63.5%; and 1992, 56.4 percent. In all cases the frequencies
of occurrence for individual compounds ranged from 0% to 100 percent. Toluene and isopentane
were found to be among the most prevalent compounds and had some of the highest mean
concentrations. In addition, high levels of 2,2-dimethylbutane and w-propylbenzene were present
in 1992, high levels of propane and w-butane were present in 1993, and high levels of isobutane,
ethane, w-butane, n-pentane, and propane were present in 1994. The highest mean concentrations
were: 1994, 23.53 ppbC of isopentane; 1993, 19.10 ppbC of isopentane; and 1992, 23.42 ppbC of
2,2-dimethylbutane. The highest observed concentrations were: 1994, 369.98 ppbC of isobutane;
1993, 380.10 ppbC of propane; and 1992, 182.16 ppbC of w-propylbenzene.
All three of the Birmingham, AL sites exhibited similarities. In each case toluene and
isopentane were prevalent. These compounds are generally indicative of mobile emissions.
Benzene, acetylene, and ethylene are also produced by mobile emitters, and concentrations of
these species were also significant at each of the three sites. Overall frequencies of occurrence
were higher at B1AL than at B2AL and B3AL, possibly due to the suburban setting. B2AL and
B3 AL are located in rural residential and agricultural settings, respectively.
2.2.2.5 El Paso, TX (EPTX)
Speciated NMOC data for EPTX were examined back to the inception of the program at
this site in 1991. Average frequencies of occurrence for the 78 target compounds remained
relatively constant: 1994, 87.5%; 1993, 84.4%; 1992, 87.2%; and 1991, 83.9 percent. In all
cases, the frequencies of occurrence for individual compounds ranged from 0% to 100 percent.
650-000-03-07/cah 2-27
-------
Toluene and propane were found to be among the most prevalent compounds with the highest
mean concentrations. In 1994, some abnormally high readings of isopentane, 3-methylpentane,
and «-hexane were observed in the sample taken on September 14, 1994, with maximum
measured concentrations of 3370.75 ppbC n-hexane, 2393.21 ppmC of 3-methylpentane, and
2215.17 ppbC of isopentane. These three species also exhibited the highest concentration
standard deviations encountered, indicating that large variations in the observed levels were
present. A few atypically high readings would account for this. The highest mean concentrations
observed were: 1994, 55.21 ppbC of isopentane; 1993, 36.00 ppbC of propane; 1992, 40.81
ppbC of toluene; and 1991, 36.88 ppbC of toluene. The highest observed concentrations were:
1994, 3370.75 ppbC of n-hexane; 1993, 305.30 ppbC of propane; 1992, 235.92 ppbC of propane;
and 1991, 281.86 ppbC of propane.
This site is located in an urban setting with large numbers of mobile sources, including
automobiles and trains, in the immediate vicinity. Because of this close proximity, anomalous
readings might be expected as a result of wind conditions.
2.2.2.6 Ft Worth, TX (FWTX)
Speciated NMOC data for FWTX was examined back to the inception of the program at
this site in 1992. Average frequencies of occurrence for the 78 target compounds were lower in
1993 than in either 1992 or 1994: 1994, 79.2%; 1993, 64.6%; and 1992, 71.4 percent. In all
cases the frequencies of occurrence for individual compounds ranged from 0% to 100 percent.
Toluene and isopentane, both indicative of mobile source emissions, were found to be among the
most prevalent compounds and had some of the highest mean concentrations. In addition, high
levels of ethane and propane were present in 1992, high levels of propane, ethane,
2,2-dimethylbutane, and w-butane were present in 1993, and high levels of 2,2-dimethylbutane,
ethane, w-butane, and propane were present in 1994. The highest mean concentrations were:
1994, 29.33 ppbC of isopentane; 1993, 18.20 ppbC of isopentane; and 1992, 26.32 ppbC of
toluene. The highest observed concentrations were: 1994, 329.44 ppbC of w-butane; 1993,
236.60 ppbC of isopentane; and 1992, 218.21 ppbC of toluene.
650-008-03-07/cah
2-28
-------
Some of the highest levels of the heavier hydrocarbons (with carbon number * Cn) were
found at this site. This is likely a result of its location next to an airport. Jet aircraft use a
kerosene based fuel (Jet-A) which has a higher overall molecular weight than automotive fuels.
Jet-A fuel may contain significant quantities of species with carbon numbers higher than 14;
however, the analytical methods used in this study were not suitable for detection of these species
since they focused on gas-phase compounds.
2.3 Precision
The precisions of the analytical and sampling techniques used during the 1994 program
were investigated and the results are presented in the following sections. Duplicate samples were
collected and analyzed to provide an indication of the sampling and analytical precision of the
techniques used. Each of the duplicate samples was analyzed in replicate to provide an indication
of the analytical precision of the techniques used. Replicate analyses from a single sample canister
are used to determine analytical precision. The first analysis was performed on the day the
canister was received from the sample site, and is designated in the table in Appendix F and G by
an "F in the Radian ID# column. The second analysis from the canister was performed at least 24
hours after the first analysis and is designated in the table in the appendix by an "R". This
procedure was followed to ensure that sufficient time had elapsed between removal of an aliquot
for analysis to allow the canister contents to equilibrate with the canister surfaces and to allow any
concentration gradients within the canister to disperse.
2.3.1 NMOC Base Program
The precisions for the NMOC Base Program are presented in the following sections.
2.3.1.1 Sampling and Analytical Precision
A summary of the duplicate analysis results for the 1994 NMOC base program appears
in Table 2-12. The raw data is given in Appendix F. Percent differences between canister means
ranged from -31.606% to 32.999% and averaged 0.223% overall. The low overall average
650-008-03-07/cah 2-29
-------
percent difference indicates that there was no systematic bias between samples. The absolute
percent difference for 1994 averaged 9.42%, which compares favorably to previous years results:
1993, 12.63%; 1992, 15.63%; 1991, 15.77%; 1990, 7.59%; and 1989, 10.62 percent.

2.3.1.2 Analytical Precision
Replicate (or repeated) analysis results for the NMOC base program are listed in
Table 2-13. The raw data is given in Appendix G.
A total of 52 analyses on 26 canister samples were performed. The percent difference
ranged from -18.840% to 15.602%, and averaged -0.569% overall. The low overall average
percent difference indicates an insignificant average bias between the first and second analyses and
excellent analytical precision.
The overall absolute percent difference was 7.27% for 1994. This compares very
favorably with results from previous years: 1993, 22.54%; 1992, 21.61%; 1991, 14.29%; 1990,
7.59%; and 1989, 8.24 percent.

2.3.2 Speciated NMOC Option to the NMOC Base Program
The precisions for the Speciated NMOC Option are presented in the following sections.
2.3.2.1 Sampling and Analytical Precision
For each of the Speciated NMOC option sites, one duplicate pair of samples was
randomly chosen for analysis. Pooled standard deviations for the duplicate samples were
calculated as an indication of sampling and analytical precision. The combined data for all sites is
presented in Table 2-14. The duplicate pooled standard deviations show similar results for each
compound, indicating that the duplicate sampling procedure provided representative ambient air
samples. Pooled standard deviations may be thought of as an average of a group of standard
deviations: The squares of the standard deviations are averaged, and the square root is taken of
that result. This value is the pooled standard deviation.
The overall average absolute percent difference, which is used to indicate precision of
two data points, is 25.69 percent. This compares with the values of 22.62% and 13.99% in 1993
and 1992, respectively.

2.3.2.2 Analytical Precision
Each of the duplicate sample pairs was also analyzed in replicate to measure analytical
precision. The summary statistics for the option sites in terms of average concentrations, average
absolute percent differences, and pooled standard deviations are presented in Table 2-15. The
data show an analytical precision with an overall absolute percent difference of 44.78 percent.
This compares with the values of 22.15% and 10.92% in 1993 and 1992, respectively.
2.3.3 Carbonyl Option to the Base NMOC Program
The precisions for the NMOC Carbonyl Option are presented in the following sections.
2.3.3.1 Sampling and Analytical Precision
Sampling and analytical precision was measured as the standard deviation and relative
standard deviation for the results from field duplicate samples which were analyzed in replicate.
The precision results for PLNJ are summarized in Table 2-16 where there was one duplicate pair
and those for NWNJ in Table 2-17 where there were two duplicate pairs. The raw data is given
in Appendix H. The duplicate analyses were performed on approximately 10% of the samples
from each site. The overall average standard deviation for PLNJ was 0.07 ppbv with an overall
relative standard deviation of 9.34%, and for NWNJ the overall average standard deviation was
0.14 ppbv with an overall relative standard deviation of 17.11 percent. These values are
comparable to those encountered in previous years. PLNJ: 1993, 8.94%; and 1992, 37.27%.
NWNJ: 1993, 14.14%; and 1992, 9.78 percent.
Relative standard deviation and absolute percent difference are similar statistics and
provide similar information. Often absolute percent difference is used when comparing two data
points, whereas relative standard deviation is used when comparing a greater number of data
points.

2.3.3.2 Analytical Precision
The analytical precision was measured as the average standard deviation of the replicate
analyses performed on the paired duplicate samples. The analytical precision results for PLNJ and
NWNJ are given in Appendix I. The replicate analyses were performed on approximately 10% of
the samples from each site. The average standard deviation for PLNJ was 0.08 ppbv with a
relative standard deviation of 11.21% (compared to 5.55% in 1993 and 6.83% in 1992) and an
absolute percent difference of 15.40 percent. For NWNJ the average standard deviation was
0.14 ppbv with a relative standard deviation of 15.55% (compared to 11.97% in 1993 and 6.16%
in 1992) and an absolute percent difference of 22.00 percent. Combining results from all replicate
samples at both sites produces an average standard deviation of 0.12 ppbv (compared to
0.17 ppbv in 1993 and 0.27 ppbv in 1992) with a relative standard deviation of 14.54% and an
absolute percent difference of 20.43 percent.
2.3.4 Speciated NMOC Base Program
The precisions for the Speciated NMOC Base Program are presented in the following
sections.
2.3.4.1 Sampling and Analytical Precision
For each of the five Speciated NMOC base sites eight to nine duplicate sample pairs
were collected and analyzed, for a total of 42 samples. Pooled standard deviations for the
duplicate samples were calculated as an indication of sampling precision. Appendix J presents the
data for all sites. The duplicate pooled standard deviations show similar results for each
compound, with an overall average pooled standard deviation of 0.41 ppbC, indicating that the
duplicate sampling procedure provided representative ambient air samples. The overall average
percent difference is 34.46%, which is higher than those values of 12.70% for 1993 and 13.83%
for 1992, likely due to the smaller sample set in 1994.

-------
2.3.4.2 Analytical Precision
For each program site, the duplicate sample pairs were also analyzed in replicate to
measure analytical precision. Seven or eight pairs were chosen at each site, for a total of 39
samples. Appendix K summarizes the statistics for the five base sites in terms of average
concentrations, average absolute percent differences, and pooled standard deviations. The
duplicate pooled standard deviations show similar results for each compound, with an overall
average pooled standard deviation of 0.36 ppbC, indicating good results for analytical precision.
The overall average percent difference is 3 5.14%, which is higher than the values of 11.46% and
11.81% for 1993 and 1992, respectively, likely due to the small sample set in 1994.
2.3.5 Toxics Option to the NMOC and Speciated NMOC Base Programs
The precisions for the Toxics Option are presented in the following sections.
2.3.5.1 Sampling and Analytical Precision
For each of the five sites which chose to participate in the Toxics Option program, one
duplicate sample pair was collected and analyzed. The minimum, maximum, and mean differences
between sample pairs were calculated, as were the standard deviations and absolute percent
differences. Table 2-18 contains a summary of the data for only those compounds detected. The
overall average standard deviation was 0.097 ppbv, indicating that the duplicate sampling
procedure provided representative ambient air samples. The overall average absolute percent
difference between duplicate sample analyses was 7.24%, which compares very favorably to the
values of 19.21% for 1993 and 16.01% for 1992.

2.3.5.2 Analytical Precision
For each program site, the duplicate sample pairs were also analyzed in replicate to
measure analytical precision. Table 2-19 summarizes the statistics for all sites in terms of
minimum, maximum, and mean differences between replicate analyses of each sample, as well as
the standard deviations and absolute percent differences. The overall average standard deviation
was 0.354 ppbv. The overall average absolute percent difference was 34.69%, for a small number
of samples (10 cases) involved. This value compares with values of 20.80% for 1993 (80 cases)
and 18.73% for 1992 (76 cases).
2.4 Accuracy Results
In order to measure the accuracy of the 1994 NMOC Program analytical results, Radian
analyzed audit samples provided by the EPA and had some samples analyzed by an independent
EPA laboratory for comparison purposes. The results of these analyses are presented in the
following sections.
2.4.1 External Audit Results
Audit samples were provided to Radian by the EPA through ManTech, Incorporated.
Results of the analyses of these samples are presented in the following sections. The EPA audit
reports are given in Appendix L.
2.4.1.2 NMOC Audits
Primary measures of accuracy for the NMOC monitoring data were calculated from the
results of the analysis of propane audit samples provided by the EPA. Results are reported in
terms of percent bias relative to the reference lab concentration value. Two audit samples,

2.4.1.2 Speciated NMOC Audits
A measurement of accuracy for the speciated NMOC monitoring data was calculated
from the results of the analysis of multicomponent audit samples provided by the EPA. Two
external audit samples, ID 1517 and 1518, were provided. Sample 1518 contained a foil range of
Speciated NMOC compounds while 1517 contained a limited subset. Results of the analyses of
1517 and 1518 are contained in Tables 2-21 and 2-22, respectively. The theoretical values are
those determined by the external reference laboratory. The spiked values were calculated using
dilution factors estimated when the audit samples were prepared by the EPA Auditor. The
analyzed values were those determined analytically by the auditing laboratory. The reported
average value is the average of the values obtained from replicate analyses by the Radian

Laboratory. The percent bias results were calculated from both the spiked and analyzed
theoretical values. The results show good analytical accuracy in both cases. The first audit
sample, ID 1517, showed a percent bias ranging from 12.67% for 2-methylpentane, to 24.40% for
n-pentane, with an average of 18.87% using the spiked value. The range of percent bias was
8.66% for isobutane to 8.98% for propane, with an average of 4.79% using the analyzed
reference value. The second audit sample, ID 1518, showed a percent bias ranging from -26.27%
for acetylene to 27.69% for benzene, with an average of 4.06% using the spiked value. The range
of bias was -24.16% for 2-methyl-l-pentene to 23.54% for undecane, with an average of 1.68
percent.
In each of the audit samples one compound was misidentified. In 1517 w-butane was
reported as 1,3-butadiene, and in 1518 1,2,4-trimethylbenzene was reported as 1-decene. In
addition, in the analysis of 1518, no ethane was recovered or reported for the sample.
2.4.1.3 Carbonyl Audits
Four audit samples, ID 3414, 3415, 3416, and 3417 were analyzed during the 1994
NMOC Carbonyl Option program. In addition, a non-spiked blank cartridge sample, ID 3413,
was also analyzed. Three target analytes, formaldehyde, acetaldehyde, and acetone, were
quantified. The results are presented in Table 2-23. The theoretical values were those determined
by the reference laboratory. Percent bias results were calculated relative to the theoretical values
and, for the non-blank samples, ranged from -21.67% for acetaldehyde in sample ID 3415 to
5.00% for acetone in sample ID 3414. The overall average percent bias was -5.02 percent.

2.4.1.4 Toxics Audits
One toxics audit sample was analyzed during the 1994 NMOC and Speciated NMOC
Toxics Option program. Table 2-24 contains the results. The theoretical values were those
determined by the reference laboratory. The spiked values were calculated using dilution factors
estimated when the audit samples were prepared by the EPA Auditor. The analyzed values were
those determined analytically by the auditing laboratory. Percent bias results were calculated
relative to both the theoretical values. The bias ranged from -40.31% for 1,2-dichloropropane, to
11.55%, for styrene, with an overall average percent bias of-18.54% using the spiked value and
-42.12% for 1,2-dichloropropane to 2.23% for dichloromethane with an average of-16.12%
using the analyzed value.
2.4.2 Speciated NMOC Comparison Samples
For each of the five Speciated NMOC base sites involved in the 1994 program, two or
three randomly selected samples, for a total of 12, were submitted to the EPA National Exposure
Research Laboratory for independent analysis. The results of these analyses are contained in

Appendix M. A summary of the percent bias by compound is given in Table 2-25. Radian did not
analyze for l-methyl-4-isopropylbenzene; therefore, no results are given for this compound. The
bias ranged from -0.68% for propene to 134.29% for 2,2-dimethylbutane with an overall average
bias of 7.36 percent. All Radian results for 2,2-dimethylbutane were significantly higher than the
reference lab, indicating the presence of a co-eluting compound or possible misidentification.
There was fairly good agreement between the results for compounds with concentrations greater
than l.OppbC.
The general trend of the Radian results were bias low as can also be seen by comparing
the total NMOC values in Table 2-26. Total NMOC bias results ranged from -50.3 to -14.2%,
with an overall average of-29.2 percent.
Of all the compounds identified by the reference lab, 14% were reported as not detected
by Radian. Of that 14%, 92% had concentrations less than 1 ppbC. This indicates the lower
sensitivity of the Radian measurement system.
2.5 Completeness Results by Program
Not all of the samples from the various base programs and their options were collected
as scheduled. Completeness results, indicating the percentage of samples that were collected as
scheduled, are presented in the following sections.
2.5.1 NMOC Base Program
For the 1994 NMOC program 223 of the scheduled 241 samples were taken on
schedule. The 18 missed samples resulted in an overall percent completeness of 92.5 percent.
Percent completeness by site ranged from 89.2% at LINY, to 98.7% at NWNJ. Table 2-27
contains data from each of the base sites involved in the program. The overall completeness value
for 1994 is comparable to completeness figures for previous years of the program: 1993, 94.5%;
1992, 90.7%; 1991, 94.1%; 1990, 95.8%; 1989, 95.5%; 1988, 93.4%; 1987, 95.0%; 1986,
96.8%; 1985, 95.8%; and 1984, 90.6 percent. Figure 2-2 shows the sampling completeness for

the history of the NMOC program. Equipment malfunction was identified as the primary cause of
missed samples, producing 53 percent. Operator error contributed 30% of the voids, and
laboratory error accounted for 17 percent. Table 2-28 details the invalid samples.
2.5.2 Speciated NMOC Base Program
For the 1994 Speciated NMOC program, 393 of the scheduled 410 samples were taken
on schedule. The 17 missed samples resulted in an overall percent completeness of 95.9 percent.
Percent completeness by site ranged from 93.8% at FWTX, to 98.8% at EPTX. Table 2-29
contains data from each of the base sites involved in the program. The overall completeness value
of 95.9% for the 1994 program compares favorably to that of 93.8% from 1993. Equipment
malfunction was identified as the primary cause of missed samples, producing 59 percent. The
remaining 41% of the missed samples came about through operator error. Table 2-30 details the
invalid samples.

3.0 AEROMETRIC INFORMATION RETRIEVAL SYSTEM -AIR QUALITY
SUBSYSTEM (AIRS-AQS)
The program data was submitted to the Air Quality Subsystem of the Aerometric
Information Retrieval System (AIRS), which is a computer-based system for handling the storage
and retrieval of information pertaining to airborne pollutants. It is administered by the U.S.
Environmental Protection Agency, Office of Air Quality Planning and Standards, Monitoring and
Data Analysis Division, National Air Data Branch (NADB). The AIRS Air Quality Subsystem
(AQS) contains data submitted to NADB by state and local agencies and EPA organizations.
This data corresponds to that previously handled by the Storage and Retrieval of Aerometric Data
(SAROAD) system. It includes descriptions of air monitoring sites and equipment, measured
concentrations of air pollutants and related parameters, and calculated summary and statistical
information.
All NMOC, Speciated NMOC, toxic, and carbonyl data collected for the 1994 NMOC
program were submitted to the AIRS-AQS in the form of transactions. A transaction provides
the monitoring information for a particular parameter (compound) for a given day. One line
transaction is required for each compound for each sample date. Prior to submittal to AIRS, all
data must be formatted to conform to the 80-character per line format required by AIRS and
saved as an ASCII text file.
Within a transaction are fields corresponding to specific information. A field or "slot" is a
column or set of columns in the 80-character input line where a specific piece of data is placed.
Four general types of values are used to code the transactions, codes, dates, numeric data, and
alphanumeric data. Codes must be entered exactly as they are stored in the Geo-Common
Subsystem of AIRS. For example, a county code is three digits and all three digits of the code
must be entered, including any leading zeros. Dates are entered in the YYMMDD format and
again, leading zeros must be entered. Numeric values must be entered right-justified and do not
have to include leading zeros. Alphanumeric values should be entered left-justified in the field.
The structure and placement of the fields in each transaction is specific and must be carefully
followed.
650-008-03-07/cah 3-1
-------
All data collected were entered into AIRS. Quantifiable data below the detection limits
were entered as the quantified value. The raw data values will be retained within AIRS, but when
any summary statistics are generated the system will automatically replace values below the
detection limits with a value that is one-half of the detection limit before performing the
calculations. Raw data listings will maintain the actual values. If the compound response is
below the detection limit and the data are not quantifiable, a concentration value of zero is entered
into AIRS. This will indicate to AIRS that the compound of interest was analyzed for but not
present at any quantifiable level. If a sample is missed or invalidated for any reason, appropriate
null values or validity flags are used.

4.0 CONCLUSIONS AND RECOMMENDATIONS
This section summarizes the conclusions and recommendations from the 1994 NMOC and
Speciated NMOC base program.
4.1 Conclusions
The NMOC and Speciated NMOC program result data for 1994 is comparable to
historical data collected for the sites participating in previous programs back to 1988. No
discernable trends are apparent in the data when compared by month or overall.
Sampling and analytical precision for the overall program compares favorably with
previous years. The NMOC base program sampling and analytical precision is more precise than
the previous two years. The Speciated NMOC base program precision values are higher than
those for 1992 and 1993. The Speciated NMOC option, toxics and carbonyl option sampling and
analytical precision is comparable to previous years.
The audit results generated by the methodology used for NMOC, Speciated NMOC, and
carbonyl analyses are very good and no significant bias or error is indicated. Bias was determined
for both the calculated and measured theoretical values. The audit results from the toxics option
analyses indicate an overall average negative bias of-17.33 percent with a maximum bias at
-42.12% for 1,2-dichloropropane.
The independent EPA analysis of twelve selected Speciated NMOC samples indicates and
overall negative bias both on a compound-specific and total NMOC basis. No sample drying
devices were used with either the Radian or EPA analytical system. This discrepancy may be the
result of differences in the analytical system sensitivities or calibration gases used; however, the
overall Speciated NMOC audit results were good (overall bias of 4.06 and 1.68) and indicates the
accuracy of the calibration gases used. The calibration gases are also checked against an National
Institute of Standards and Technology (NIST) certified propane standard to verify the accuracy of
the calibration gases.
650-008-03-07/cah
4-1
-------
The overall NMOC and Speciated NMOC program completeness was 92.5 and 95.9%,
respectively, which compares favorably with past years programs. Equipment malfunction was
identified as the primary cause with just over 50% of the invalid samples attributed to this reason.
The primary equipment failures were leaking canisters, solenoid valves, and pump failures.
4.2 Recommendations
The following are recommendations for future NMOC and Speciated NMOC programs.
4.2.1 Canister Age
Many of the EPA canisters have been in service since the program's inception in 1984. It
is recommended that a subset of the oldest canisters be evaluated to determine the condition of
the SUMMA®-passivation and any surface activity conditions that may be present.
4.2.2 Field Audit
It is recommended that a field audit be designed and conducted at the NMOC and
Speciated NMOC sites during subsequent monitoring programs. A minimum of one audit should
be performed at each site and should consist of the duplicate collection of a humidified standard at
known concentration in addition to the collection of a humid zero air field blank sample.
4.2.3 Sampling Equipment
It is recommended that the solenoid valves and pumps be replaced in all samplers deployed
for the next sampling effort. Equipment malfunction was identified as the primary cause of invalid
samples with just over 50% attributed to solenoid valve and pump failures.

-------
4.2.4 Option Program Sample Selection
Samples for the Speciated NMOC and toxics option programs are currently selected
randomly, or when abnormally high levels of total NMOC or speciated NMOC are noted. If
unusual samples are included in the sample set, statistical results may be afifected. If the purpose
of the option program data is to provide more definitive species information, it is recommended
that the samples be chosen randomly, not selectively.

5.0 NMOC BASE PROGRAM
5.1 Program Description
Three NMOC base sites participated in the 1994 program, they were located in Long
Island, NY (LINY), and Newark and Plainfield, NJ (NWNJ and PLNJ). The NMOC site AIRS
codes are given in Table 1-1. The Long Island site has been in the NMOC program since 1990;
the Newark site has participated in the program since 1987; and the Plainfield site has participated
since 1988. Both NWNJ and PLNJ also included the 3-hour toxics, carbonyl, and speciated
NMOC analysis options. LINY chose the Speciated NMOC analysis option. Approximately ten
canister samples were selected from each site for the toxics and speciated analysis; both analyses
were performed on the same sample. Approximately ten 3-hour carbonyl samples were collected
at each site for analysis by Compendium Method TO-11.5
The NMOC program consists of several activities that include:
• Sample collection, site coordination, equipment certification, installation, and
operator training, and post-sample collection activities, such as equipment
recovery and refurbishment, and canister cleanup and archive;
• Sample analysis, data reduction, validation, and reporting;
• Statistical analyses and data characterization; and
• Formatting and submittal of the validated data to the AIRS-AQS.
Sample collection for the 1994 NMOC base program occurred from 6:00 a.m. through
9:00 a.m. local time, Monday through Friday from July 6 through October 31, 1994. Two
hundred sixty-eight samples were collected for all sites, which includes 27 duplicate samples.
Duplicate sample canisters were analyzed in replicate, except where low pressure precluded a
second analysis. Sample analyses were performed in accordance with the Compendium Method
TO-12.2 This methodology incorporates preconcentration direct flame ionization detection
(PDFJD) gas chromatography and provides a total hydrocarbon measurement without speciation.

5.2 Sample Collection Procedures
This section summarizes the sample collection procedures, which include the sample
collection method, equipment preparation and certification, equipment calibration, equipment
installation and training, and the sample collection schedule.
5.2.1 Sample Collection Method
The field sampling equipment used to collect ambient air samples for NMOC
measurements consisted of three basic components: The sampling manifold, the sampling system,
and the sample canister. A schematic diagram is shown in Figure 5-1.
The sampling manifold involved two configurations; a slip stream taken from a constant
flow glass manifold (prior to the air monitoring station's NOX analyzer), or separate but collocated
NMOC and NOX sample inlet lines. Glass tubing or gas-chromatographic-grade stainless steel
tubing and stainless steel fittings were the materials of construction for all connections that came
in contact with the sample.
The sampling unit drew ambient air through a sintered stainless steel filter, a glass
rotameter, a stainless steel fine adjustment metering valve, a Metal Bellows® pump, a solenoid
valve, and then finally into a SUMMA® treated stainless-steel canister. The sample collection
period was controlled by a programmable timer that operates the pump, the solenoid valve, and an
elapsed time meter.
A 6-liter SUMMA® canister with an initial vacuum of about 29 in. Hg was attached to
the sampling system. At the completion of the three-hour sampling period, the canister reaches a
nominal final pressure of about 12 psig.

5.2.2 Equipment Preparation and Certification
Set procedures were followed when preparing equipment for use and certifying it as
ready. These procedures are explained in the following sections. Equipment includes SUMMA®
passivated canisters and single event sampling systems.
5.2.2.1 Canister Cleanup System
A canister cleanup system was developed and used to prepare sample canisters for
reuse after analysis. A cleanup cycle consisted of first pulling a vacuum of 0.5 mm Hg absolute
pressure in the canister, followed by pressurizing the canister to 20 psig with cleaned, dried air
that had been humidified. This cycle was repeated two more times during the canister cleanup
procedure. The cleanness of the canister was qualified by PDFID analysis. Upon meeting the
cleanness criterion of 20 ppbC, the canister was evacuated to 0.5 mm Hg absolute pressure a
fourth time, in preparation for shipment to the site.
5.2.2.2 Canister Cleanup Equipment
An oil-free compressor with a 12-gallon reservoir provided source air for the canister
cleaning system. The oil-free compressor was chosen to minimize hydrocarbon contamination. A
coalescing filter provided water mist and paniculate matter removal down to a particle size of one
micron. Permeation dryers removed water vapor from the compressor source air. These
permeation dryers were followed by moisture indicators to show detectable moisture in the air
leaving the dryer. The moisture indicators never showed any water, indicating that the
permeation dryers effectively removed all water vapor.
Air was then passed through catalytic oxidizers to destroy residual hydrocarbons. The
oxidizers were followed by in-line filters for secondary paniculate matter removal and by a
cryogenic trap to condense any water formed in the catalytic oxidizers and any organic compound
not destroyed by the catalytic oxidizer. A single-stage regulator controlled the final air pressure in
the canisters and a metering valve was used to control the flow rate at which the canisters were
650-008-03-07/cah
5-4
-------
filled during each cleanup cycle. The air flow was indicated by a rotameter installed in the clean,
dried air line. A shutoff valve was located between the rotameters and the humidifier system.
The humidifier system consisted of a SUMMA® treated 6-L canister partially filled with high
performance liquid chromatographic-grade (HPLC-grade) water. One fiowmeter and flow-
control valve routed the cleaned, dried air into the 6-L canister where it was bubbled through the
HPLC-grade water. A second flow-control valve and fiowmeter allowed air to bypass the
canister/bubbler. By setting the flow-control valves separately, the downstream relative humidity
was regulated. Since the 1990 study, 80% relative humidity has been used for canister cleaning.
Another shutoff valve was located between the humidifier and the 8-port manifold where the
canisters were connected for cleanup.
The vacuum system consisted of a Precision Model DD-310 turbomolecular vacuum
pump, a cryogenic trap, an absolute pressure gauge, and a bellows valve. The cryogenic trap
prevented the sample canisters from being contaminated by back diffusion of hydrocarbons from
the vacuum pump into the cleanup system. The bellows valves enabled isolation of the vacuum
pump from the system without shutting off the vacuum pump.
5.2.2.3 Canister Cleanup Procedures
After all analyses were completed, a bank of eight canisters was connected to each of
the canister manifolds. The valve on each canister was opened, with the shutoff valves and the
bellows valves closed. The vacuum pump was started and one of the bellows valves was opened,
drawing a vacuum on the canisters connected to the corresponding manifold. After reaching
0.5 mm Hg absolute pressure as indicated by the absolute pressure gauge, the vacuum was
maintained for 30 minutes on the eight canisters. The bellows valve was then closed and the
cleaned, dried air that had been humidified was introduced into the evacuated canisters until the
pressure reached 20 psig. The canisters were filled from the clean air system at the rate of
7.0 L/min. This flow rate was recommended by the manufacturer as the highest flow rate at
which the catalytic oxidizers could handle elimination of hydrocarbons with a minimum of 99.7%
efficiency.
650-008-03-07/cah
5-5
-------
When the first manifold had completed the evacuation phase and was being pressurized,
the second manifold was then subjected to vacuum by opening its bellows valve. After 30
minutes, the second manifold was isolated from the vacuum and connected to the clean, dried air
that had been humidified. The first manifold of canisters was then taken through a second cycle
of evacuation and pressurization. Each manifold bank of eight canisters was subjected to three
cleanup cycles.
During the third cleanup cycle, the canisters were pressurized to 20 psig with clean,
dried air that had been humidified. For each bank of eight canisters, the canister having the
highest pre-cleanup NMOC concentration was selected for NMOC analysis to determine potential
hydrocarbon residues. If the analysis measured less than 0.020 ppmC, then the eight canisters on
the manifold were considered to be clean. Finally, the canisters were again evacuated to
0.5 mm Hg pressure absolute, capped under vacuum, and then packed in the containers used for
shipping to the field sites.
5.2.2.4 Sampling System
In 1994 all samplers used an OMRON® H5L timer in place of the Dayton® timer used
in previous years. The new timer provided greater reliability in the event of a power outage and
more accurate timekeeping. In addition to the modifications, all samplers were subjected to a
pre-season check to ensure field performance. The in-line rotameters were calibrated against a
primary standard (bubble-flow meter) and the linear regression results from the curves used to
determine the sampling flow rate settings for each individual sampler. Three flow measurements
were taken at three flow settings to encompass the range of operation. The measurements were
made under simulated field conditions: the pump running and an evacuated canister filling
normally. The calibration information was used to nominally set the flow rates. Actual final
canister pressures were used to determine if the flow rate settings needed adjustment.
The samplers were then pressure and vacuum leak checked for 24-hour periods by
attaching sample canisters at 12 psig and 29 in. Hg vacuum, respectively, and taking periodic
readings of the in-line pressure/vacuum gauge. A vacuum change of 1 inch or less Hg vacuum
650-008-03-07/cah
5-6
-------
and a pressure change of 1 psig or less was considered acceptable. The samplers were also
operated at their calculated flow rate to demonstrate valid 3-hour collection.
All samplers were blanked by Compendium Method TO-122 to determine initial
cleanliness. The blanking procedure consisted of a 50% wet/50% dry zero air purge through the
entire sampling system and stainless steel manifold for 24-72 hours, followed by a 30-minute
100% dry zero air purge to "dry" the manifold and samplers, then by a 15-minute 100% wet zero
air purge of the manifold only, and a 3-hour collection of 50/50 wet/dry air through the samplers
into clean blanked sample canisters. The canisters were analyzed by the PDFID (TO-12) method
in the same manner as an NMOC sample. The criteria used to determine sampler cleanliness was
the same as the criteria used for canister cleanliness: 0.020 ppmC.
The samplers that were also collecting samples for the air toxics option analyses were
challenged with a multi-component standard. Samplers were purged with 100% wet zero air at
the maximum sample flow rate for 12 hours. The challenge manifold was then heated to 100%
and purged with 100°C wet zero air purge of the manifold and samplers. The manifold and
samplers were then conditioned for 15 minutes with 50% dry/50% wet zero air and an additional
15 minutes with the pollutant gas mixture. Samples were collected for 3 hours and analyzed on a
multi-detector (FID/PID/ECD) gas chromatograph. The pollutant concentration of the challenge
gas was determined by collecting a reference canister directly from the challenge manifold. The
results are given in Table 5-1. Satisfactory results are in the 100% ± 30% recovery range. AD
recoveries fell within the 100% ± 30% range. Samplers were then purged for about 4 days with
50/50 wet/dry air to ensure cleanliness and PDFID blanked for cleanliness.
5.2.3 Sampling Equipment Installation and Training
NMOC sampler installation was performed by, or under the direction of, Radian
personnel. The installation requirements included a temperature-controlled environment (70°F to
86°F) located in close proximity to the atmosphere to be sampled, and noncontaminating sampler
connections. Site operators were trained on sampler operation, documentation, and sample
handling and shipping. A notebook containing operating and shipping instructions was also

provided. In addition to the notebook, a list of troubleshooting instructions and common
operator errors were provided to minimize downtime. Field site operators were encouraged to
relay sampling and site problems immediately to Radian by telephone. Most sampling problems
were handled through these telephone discussions by the Radian Site Coordinator.
5.3 Sample Collection Quality Control
Quality Control procedures relative to calibration data for all of the analytes and daily
QC procedures are discussed below. Sampling and analysis precision was determined from the
analysis of duplicate field samples and replicate laboratory analyses. Sample custody records
were maintained throughout the program. Figure 5-2 shows the field data and custody sheet used
for NMOC sampling documentation. The site operator's task involved recognizing problems with
sampling equipment and procedures, and notifying Radian personnel so that appropriate
corrective action might be taken. All Radian reported analyses were identified by the NMOC
identification numbers which were recorded on the preformatted field data sheets when the
samples were received. Copies of the field data sheets were kept in a ringbinder for reference.
Samples were received and the pertinent information recorded in a sample logbook.
5.4 Calibration and Sample Analysis
The NMOC analysis equipment and procedures used are similar to those described in
detail in Compendium Method TO-12.2 A brief description of the equipment and operating
procedures used in this study follows.
5.4.1 Instrument Performance and Daily Calibration
An initial multipoint performance evaluation was conducted on each analytical
measurement channel, using propane referenced to a propane NIST CRM No. 1666B. This
information is used to determine the instrument performance and dynamic linear range. The
concentration of the propane used in the performance assessment ranged from 2.971 to
19.073 ppmC. The "zero" value was determined using cleaned, dried air from the canister

Radian PDFID channels were tested daily for zero and span. Zero readings were
measured using cleaned, dried air. The zero air was supplied by the same system that cleans the
air for the canister cleanup system. Span readings used a mixture of about 3.0 ppmC propane in
dry air. The daily calibration response factors were used to determine NMOC concentrations for
the day. Calibration factors were calculated from the span and zero readings for each
measurement channel. Initial calibration factors were determined in the morning before any site
samples were analyzed and final calibration factors were determine in the afternoon on randomly
selected days after all the ambient air samples had been analyzed. Percent calibration factor drifts
were determined based on the initial calibration factor. Figures 5-7 to 5-10 show the daily
calibration span data as a function of the 1994 Julian date for Radian Channels A, B, C, and D.

standards as follows:
calibrationfector = concentralionofpropaiie standard (ppm)x3ppn»C/ppm
(propane standard response [area counts] - zero response [areacounts])
5.4.3 Sample Analysis
Two gas chromatographs were used by Radian. Each was a dual-channel
Hewlett-Packard Model 5880 (HP-5880) using flame ionization detection (FID). NMOC
instrument Channels A and B refer to the two FEDs on one HP-5880 unit, and Channels C and D
refer to the two FEDs on the other HP-5880 unit. These chromatographs were configured for
PDFID analysis, consistent with methodology described in Compendium Method TO-12.2
The sample trap consisted of 30 cm of 1/8-inch outside diameter (o.d.) stainless steel
tubing, packed with 60/80 mesh glass beads. Three support gases were used for PDFTD analysis:
helium, hydrogen, and hydrocarbon-free air. The operating temperatures of the HP-5880 were
controlled for the PDFED analysis. The FED and auxiliary zone were controlled at 250°C and
90°C, respectively. The oven temperature was programmed from 30°C to 90°C at a rate of
30°C per minute for 4 minutes, holding at 90°C for the fourth minute. Oven and integration
parameters were controlled by Hewlett-Packard HP Level 4 programmable integrators.

The modified HP-5880, dual-FID chromatographs were operated during the 1994
study according to a project-specific Standard Operating Procedure (SOP). Further description is
given below to help explain the analytical apparatus and procedure.
A six-port valve was installed in the auxiliary heated zone of the HP-5880 and was
pneumatically actuated using chromatographic valve control signals to apply either compressed air
or vacuum to the valve. The sample trap itself was located inside the chromatograph's column
oven. A section of 1/8-inch o.d. stainless steel tubing was sized to a length that prevented
pressure surges from extinguishing the FID flame. This length was determined experimentally and
differs for each chromatograph and for each channel within chromatographs. Although the length
of tubing effectively substitutes for the pressure restriction provided by a column, it does not
perform the separation function of a column.
During sample trapping, an excess of sample gas flow from the canister was maintained
to ensure back diffusion of room air into the trap did not occur. A pressure change of 80 mm Hg
in a 1.7-L vacuum reservoir was used to gauge and control the volume of sample gas
cryogenically trapped. After the trapping cycle was complete, the HP-5880 program was
initiated. When the program triggered a horn emitting an audible beep, the cryogen was removed
from the trap and the oven door was closed. The chromatographic program then assumed control
of raising the oven temperature, at the preset rate, to release the trapped sample to the FID, and
set up the integration parameters.
5.4.4 Data Reduction and Validation
Secondary backup disks were updated daily on 20 megabyte hard disks. At the
completion of the sampling and analysis phase, 10% of the data base was checked to verify its
validity. Items checked included original data sheets, checks of all the calculations, and data
transfers. In making the calculations for the final report and other reports, corrections were made
to the data base as errors or omissions were encountered.

-------
A total of 256 NMOC concentration measurements were performed by Radian from
July through October 1994. This included 223 sample analyses, 29 repeated analyses, and 2 audit
samples (4 analyses each).
Ten percent of the data base was validated according to the procedure outlined below:
• Calibration factors were checked.
~ The area count from the strip chart that was used to determine the
calibration factor was examined to verify that the data had been properly
transferred to the calibration form.
The calibration form was examined to verify that the calculations had been
correctly made.
Each datum on the disk was compared to the corresponding datum on the
calibration sheet for accuracy.
• Analysis data were checked.
Area counts were verified from the appropriate strip chart.
Calculations were reverified on the analysis forms.
Each datum on the disk was compared to the corresponding item on the
analysis form.
• Field data sheet was checked.
Each datum on the disk was compared to the corresponding datum on the
field data sheet.
The error rate was calculated in terms of the number of items transferred from the original data
sources. For each NMOC value in the 1994 data set, 36 items were transferred from original
sources to the magnetic disks. In the data validation study each item on the disk was compared
with the corresponding value on the original source of data. One error was found (and corrected)
for an expected error percentage of 0.007 percent.

6.0 SPECIATED NMOC BASE AND OPTION PROGRAM
6.1 Program Description
Five Speciated NMOC base sites participated in the 1994 program and were located in
Birmingham, AL (B1 AL, B2AL, and B3 AL), Fort Worth, TX (FWTX), and El Paso, TX
(EPTX). The Speciated NMOC site AIRS codes are given in Table 1-1 and AIRS site description
inventories detailing with the site characteristics are given in Appendix A. All sites have
participated in the Speciated NMOC program since 1992, except for EPTX which started in
1991. Three of these sites (B1AL, B2AL, and B3AL) also included the 3-hour toxics analysis
option in their programs. The same procedures were used for the Speciated NMOC option sites
(LINY, NWNJ, PLNJ).
The Speciated NMOC program consists of several activities that include:
• Sample collection, site coordination, equipment certification, installation, and
operator training, and post-sample collection activities, such as equipment
recovery and refurbishment, and canister cleanup and archive;
• Sample analysis, data reduction, validation, and reporting;
• Statistical analyses and data characterization; and
• Formatting and submittal of the validated data to the AIRS-AQS.
From July 5 through October 31, 1994, 439 samples were collected for all sites, which
includes forty-five duplicate samples. One-half of all duplicate pairs were analyzed in replicate.
Sample analyses were performed in accordance with the research protocol for analysis of C^
through C12 hydrocarbons in ambient air.3 This methodology incorporates the use of gas
chromatography with dual capillary columns and flame ionization detectors (FIDs). Seventy-eight
hydrocarbons were quantitated during analysis. Chlorinated and oxygenated species were not
identified or quantified using this procedure.

6.2 Sample Collection Procedures
The sample collection procedures, which include the sample collection method, equipment
preparation and certification, equipment calibration, equipment installation and training, sample
collection schedule, and sample collection quality control are identical to those used for the
NMOC base program. Refer to Section 4.2 for a description of the procedures.
6.3 Calibration and Sample Analysis
Standardized techniques were followed during sample analysis. Calibration standards
were prepared for propane and benzene only, instruments were calibrated on schedule or when
required, samples were analyzed following published procedures, and data were examined for
accuracy. These procedures are explained in the following sections.
6.3.1 Calibration Standard Preparation
Certified high pressure stock standards from Scott® Specialty Gases were used to prepare
propane and benzene analytical calibration standards across the measurement range of the
analytical system. Standards used to establish retention time information were prepared from
stock standards made using neat liquid compounds injected into cleaned, evacuated canisters, or
from certified gaseous stock standards. Standards used to gather retention time information and
set up a reference database using relative retention times referenced to toluene were prepared and
analyzed. These relative retention times were used to identify the target compounds in the
ambient air samples.
All calibration and daily calibration check standards were made from certified standard
gases. Gas-tight syringes were used to inject an aliquot of the certified standard into cleaned,
evacuated SUMMA® canisters. The canisters were pressurized with nitrogen to approximately
25 psig using a canister dilution system that consists of a precision vacuum/pressure gauge and a
high-pressure nitrogen tank.

-------
6.3.2 Monthly and Daily Instrument Calibration
The analytical system was calibrated monthly by analyzing three hydrocarbon standards
and a system blank of cleaned, humidified air. The three calibration standards were prepared from
a Scott® Specialty Gases certified standard to levels of 5, IS, and SO ppbv benzene and propane.
This calibration range is based on the expected levels of target compound concentrations in
ambient air, based on historical information.
The calibration standards were analyzed in order of increasing concentration, and followed
by the system blank analysis to ensure no carryover after analysis of the high level standard. For
the primary column (1 /zm phase thickness), which is used to quantitate the C4 through C13
compounds, the benzene area count recorded by the FID was correlated to nanoliters of benzene
by a least squares linear regression. For the secondary column (5 ^m phase thickness), used to
quantitate the C2 and C3 compounds, the propane area count recorded by the FID was correlated
to nanoliters of propane by a least squares linear regression. The calibration was considered
representative if the coefficient of correlation for the four points was greater than or equal to
0.995 for each column/detector. The slopes of the regression lines were then used to calculate
monthly response factors.
The benzene response factor was divided by 6 (carbons/molecule of benzene) to calculate
a per carbon response factor for the primary column/detector. The propane response factor was
divided by 3 (carbons/molecule of propane) to calculate a per carbon response factor for the
secondary column/detector. These response factors were then used to calculate sample
concentrations for the following month. Monthly calibration information is summarized in
Table 6-1.
Daily, prior to sample analysis, a QC standard, prepared from a Scott® Specialty Gases
certified standard, was analyzed to ensure the validity of the current monthly response factors.
This standard had an approximate concentration of 10 ppbv propane and benzene. This level was
considered representative of the majority of concentrations expected in ambient air samples.

The load volume (in liters), benzene area count from the primary detector, and propane
area count from the secondary detector were entered into a computer spreadsheet and the current
monthly response factors were used to calculate the benzene and propane concentrations. These
concentrations were compared to the calculated theoretical concentrations of the QC standard. A
concentration percent bias of less than or equal to 30% was considered to be acceptable and the
analytical system was in control.
If the daily QC standard did not meet the 30% criterion a second QC standard was
prepared and analyzed. If the second QC standard met the criterion, the analytical system was
considered in control. If the second QC check did not pass, a leak test and system maintenance
were performed, and a third QC standard analysis was performed. If the criterion was met by the
third analysis, the analytical system was considered in control. If the maintenance caused a
change in system response, a new calibration curve was required. For the 1994 program the 30%
650-008-03-07/cah

-------
criterion was met on the first standard analysis for every sample analysis day on both analytical
systems.
A system blank of cleaned, humidified air was analyzed after the daily QC standard
analysis and prior to sample analyses. The system was considered in control if the total NMOC
concentration for the system blank was less than or equal to 20 ppbC. This criterion was met for
every sample analysis day on both analytical systems. A summary of the Speciated NMOC QC
procedures is given in Table 6-2.
6.3.3 Sample Analysis
The sample analysis method follows the general guidelines of EPA's "Research Protocol
Method for Analysis of C2 through C,2 Hydrocarbons in Ambient Air by Gas Chromatography
with Cryogenic Concentration".3 The Speciated NMOC target compounds are listed in Table 6-3
along with the Chemical Abstract Service (CAS) numbers and AIRS Parameter Code. Two
analytical systems were used for the 1994 Speciated NMOC analyses. One system uses a manual
sampling interface, the other an automated sampling interface, to concentrate and transfer the
sample aliquot from stainless steel canisters to the GC.
The GCs connected to these sample introduction systems each contained two fused-silica
capillary columns each connected to a FID. The sample is split between the columns in a 1 : 1 ratio
with a 3 -way press tight glass union. Each column has a J&WDB-l® phase. One column has a
phase thickness of 1 //m to separate C4 through C13 hydrocarbons effectively. The other has a
phase thickness of 5 f^m to separate C2 and C3 hydrocarbons.
Each system was characterized by analyzing hydrocarbon standards and the operating
conditions were determined so that the chromatography would be comparable between systems.
Each GC oven temperature was programmed so the sample is refocused on the GC column at
subambient conditions, then the temperature increases to chromatographically separate the target
compounds. Table 6-4 indicates the operating conditions for these analytical systems.

One analytical system consisted of a manual sampling interface, a Varian® 3400 dual
FID GC, and a Nelson® 2600 data acquisition system. The second analytical system consisted of
an automated sampling interface, a Varian® 3600 dual FID GC, and a Nelson® 2600 data
acquisition system.
The automated system is capable of automatically concentrating a series of 16 air
samples. In between sample loading, the sample pathway is continuously purged with humidified
air provided by the laboratory clean air generation system. The automated system uses a vacuum
pump to pull the sample into the cryogenic trap. The sample flow path consists of a mass flow
controller (MFC) which provides a signal used to electronically integrate the total sample volume
and a Nafion® dryer to remove water from the sample. The sample is cryogenically concentrated
in a nickel trap filled with nonsilanized glass beads. Injection of the sample on the GC column
occurs when the cryotrap is rapidly heated to vaporize any condensed organics, and helium carrier
gas sweeps the sample to the head of the GC column.
6.3.4 Data Reduction and Data Validation
A PE Nelson® 2600 Chromatography Data System consisting of a 900 Series Intelligent
Interface and a PC system containing the 2600 software was used to acquire, integrate and store
the analytical data. A chromatogram and area count report from each detector were printed for
each analysis. Electronic copies of the data were stored on 20 Mb disk cartridges, and a
compressed backup disk was also made.
The data were processed using Radian Peak Identification Program (RPIP) software.
The RPIP used a database containing relative retention time information for all compounds of
interest and applicable response factors to process the data files. A preliminary report was
generated containing possible peak identifications and quantitations based on the carbon response
factor in effect at the time of analysis.
A data reviewer compared the RPIP report to the chromatogram to determine proper
peak identifications. A second data reviewer checked for items which may have been overlooked

on the first pass. After the data was reviewed twice, a final RPIP report was processed and

Electronic copies of all RPIP reports were also kept on file.

7.0 3-HOUR TOXIC OPTION TO THE NMOC AND SPECIATED NMOC BASE
PROGRAMS
7.1 Program Description
Two NMOC (PLNJ and NWNJ) and three Speciated NMOC (B1AL, B2AL, and B3AL)
base sites chose the toxics option to their programs. Refer to Table 1-1 for the program
description. The toxic option program provides for subsequent toxics analysis on nine of the
samples collected for each of the two NMOC and three Speciated NMOC base sites. Of the nine
samples, one pair is a duplicate which is analyzed in replicate. The samples are analyzed using the
same procedures as used for the Urban Air Toxics Monitoring Program (UATMP). The
methodology employed is performed in accordance with Compendium Method TO-14.6
The toxic option program consists of:
• Sample analysis by GC/MSD-FID, data reduction, validation, and reporting;
• Statistical analysis and data characterization; and
• Formatting and submittal of the validated data to the AIRS-AQS
7.2 Sample Collection Procedures
The NMOC/Speciated NMOC monitoring program samples were used for the 3-hour air
toxics samples. See Section 5.2 for a discussion of the procedures used for sampling system
preparation, certification, calibration, installation and training, and quality control. The original
sample was collected as an integrated ambient air sample from 6:00 a.m. to 9:00 a.m., local time,
with a final sample pressure of approximately 15 psig. After NMOC or speciated NMOC analysis
was completed, the canister was then analyzed by GC/MSD-FID for the UATMP target analytes.

7.3 Calibration and Sample Analysis
Standardized techniques were followed during sample analysis. Calibration standards
were prepared for each of the toxics option target compounds, the GC/MSD-HD instrumentation
was calibrated, detection limits were determined, samples were analyzed following published
procedures, and data were statistically analyzed and examined for accuracy. These procedures are
explained in the following sections.
7.3.1 Calibration Standard Preparation
A monthly calibration of the target compounds was performed by analyzing humidified
standards prepared at levels of approximately 0.5, 1, 5, 10, and 15 ppbv from Scott® Specialty
Gases certified standards. A standard prepared at a level of approximately 5 ppbv from a Scott®
Specialty Gases certified standard was used for a daily quality control check. These standards
were prepared using the dynamic flow dilution system. The gases were mixed in a SUMMA®-
treated mixing sphere and bled into evacuated canisters. One dilution air stream was routed
through a SUMMA®-treated bubbler containing HPLC-grade water to humidify, and the other
stream was not humidified. The dilution air streams were brought together to mix with the
streams for the certified cylinders. Flow rates from all five streams (four from the certified
cylinders and one from the dilution cylinder) were gauged and controlled by mass flow
controllers. The split air dilution streams were metered by "wet" and "dry" rotameters from the
humidified and non-humidified dilution air streams, respectively. The system was evacuated with
a vacuum pump while the closed canister was connected. A precision absolute pressure gauge
measured the canister pressure before and after filling. The lines leading to the canister and to the
mixing sphere were flushed for at least 15 minutes with standard gas before being connected to
the canister for filling.
7.3.2 GC/MSD-FID Calibration
Initial and monthly calibration curve standards were made at approximately 0.5, 1, 5, 10,
and 15 ppbv for each of the target compounds. A linear regression was performed for each of the
65WX»-03-07/cah

-------
compounds with the objective that the correlation coefficient be 0.995 or better (for 5 or 6 points)
for selected compounds on the detector used for quantitation. The zero air used for canister
cleaning and for standards dilution was analyzed at the time of calibration, but the results were not
used in the calibration curve. Daily calibration was done with standards made from the certified
gases with an average concentration of approximately 5 ppbv.
The calibration standard concentrations and area counts for each compound were entered
into a spreadsheet. The resulting response factors of each of the compound's concentrations were
compared to the monthly calibration curve's average response factor. An absolute value of less
than or equal to 30% relative percent difference was tracked for the quantitated compounds. This
was not a criteria for calibration acceptance, but was monitored in addition to the correlation
coefficient criteria.
Prior to sample analysis, the MSD was tuned using bromofluorobenzene (BFB). The
criteria for acceptance is given in Table 7-1. Following successful tuning, the approximately
5 ppbv standard was analyzed to ensure the validity of the current monthly response factor. This
daily check was at the middle range of the calibration curve to show consistency with the monthly
calibration curve. The daily standard area counts for each compound were entered into a
spreadsheet. The resulting concentrations (cone. = response factor x area counts) of each
compound were compared to the true value on the monthly calibration curve. An absolute value
of less than or equal to 30% relative percent difference was the guideline for the quantitated
compounds. After acceptance of the daily standard, a wet zero was analyzed. Resulting
concentrations for target amounts of less than 0.2 ppbv was the objective except for known
detector interferences. If more than a 0.2 ppbv concentration was found, a second wet zero was
run. If a second wet zero failed, system maintenance was performed.
7.3.3 GC/MS Calibration Results
Four calibration curves were used during the analysis period. All of the compounds were
within the 0.995 criteria for linear regression. The 30% objective was exceeded by two of the 38
compounds. They ranged from 37.16 to 53.94 percent.

7.3.4 Detection Limits
Instrument detection limits for the 38 target toxic target compounds are given in
Table 7-2. The detection limits were determined by performing seven replicate analyses of a
standard that was at a concentration near the expected practical quantitation limit, which follows
the method listed in the Federal Register, Appendix B, Part 136.7 The detection limit for
acetylene was determined from the FID and is also given in Table 7-2.
7.3.5 Sample Analysis
The analytical system consisted of a Nutech sample concentration system and a Hewlett-
Packard GC/MSD-FID. Figure 7-1 shows the analytical system including the sample interface
system, analytical system, and data system. When the sampling valve was in the sample load
mode, the sample interface served to cryogenically preconcentrate a measurable sample volume.
In the sample inject mode, the cryogenically-focused water and organic compounds were
thermally desorbed and swept by helium carrier gas to the cryogenic focusing unit located before
the head of the GC column. The focusing unit was used to concentrate the desorbed sample into
a narrow band where it was then desorbed onto the head of the GC column where the compounds
were then chromatographically separated.
The Hewlett-Packard 5890 Series n gas chromatograph system contained a FID and a
Hewlett-Packard 5971 MSD. The system used one column (J & W DB-1®, 60 m x 0.32 mm,
and 1 urn film thickness) followed by a 1:3 splitter. Two-thirds of the effluent goes to the MSD
and the remainder goes to the FED. Compounds were identified based on a combination of
retention time, the MSD library, and the analyst's experience and judgment. Quantitation was
performed using the FID response for acetylene, with the remainder of the target compounds
quantitated using the MSD. The sample concentrations were calculated using the monthly
calibration curve average response factor.

8.0 CARBONYL OPTION TO THE NMOC BASE PROGRAM
8.1 Program Description
Two NMOC base sites participated in the 1994 carbonyl option program. The base sites
were Plainfield, NJ (PLNJ) and Newark, NJ (NWNJ). See Section 3.0 for a description of the
NMOC base program and the AIRS site codes and AIRS site description inventories dealing with
the site characteristics. Approximately ten carbonyl sample cartridges, including a duplicate pair,
were selected from each site for sample analysis.
A total of three DNPH cartridges were shipped to each site for each sampling event. Two
cartridges were used to collect duplicate samples, while the third tube, a trip blank, was used to
assess the potential for field contamination. The trip blank cartridge accompanied the duplicate
sample cartridges, but at no time was exposed to ambient air. Duplicate field samples were
collected on duplicate cartridges during each sampling event. One set of field duplicates from
each site was selected and analyzed in replicate to determine both the sampling and analytical
precision.
The carbonyl option program consists of several activities that include:
• Sample collection, site coordination, equipment installation and operator training,
and post-sample collection activities, such as equipment recovery and
refurbishment;
• Sample analysis by HPLC, data reduction, validation, and reporting;
• Statistical analyses and data characterization; and
• Formatting and submittal of the validated data to the AIRS-AQS.

8.2 Sample Collection Procedures
A schematic diagram of the 3-hour carbonyl sampling sub-system is shown in Figure 8-1.
The 3-hour carbonyl sampling subsystem collects a separate sample concurrent with the collection
of the NMOC canister sample through the use of a common sampling control system.
Ambient air was drawn from a glass manifold, through an ozone scrubber, and then
through the carbonyl sample cartridges. The ozone scrubber was maintained at 200 °F to prevent
moisture condensation. Carbonyl samples were collected in duplicate parallel cartridges during
each sample collection period. The carbonyl cartridges used were commercially available (Waters
Co.) silica gel DNPH-coated Sep-Pak® cartridges.
The carbonyl cartridges were installed in the sampling sub-system one day prior to the
scheduled sample collection. A 3-hour sample collection period, concurrent with the NMOC
canister collection, was utilized.
The flow rates through each of the duplicate carbonyl samples were controlled by flow
restrictors (or critical orifices). The collection flow rates were quantified and the rotameters
calibrated before the sampling sub-systems were shipped to the sites. The volume of ambient air
actually sampled through each cartridge was calculated based on the rotameter setting and the
field-recorded sampling duration. Typical sampling flowrates were 800-10,000 mL/min.
8.3 Sample Collection Quality Control
Quality assurance procedures relative to calibration data for all of the analytes and daily
QC procedures are discussed below. Sampling and analysis precision was determined from the
analysis of duplicate field samples and replicate laboratory analyses. Sample custody records
were maintained throughout the program. Figure 8-2 shows the field data and custody sheet used
for carbonyl sampling documentation. The site operator's task involved recognizing problems
with sampling equipment and procedures, and notifying Radian personnel so that appropriate
corrective action might be taken. All Radian-reported analyses were identified by the NMOC

8.4 Calibration and Sample Analysis
Various standard techniques were followed during sample analysis. Instrumentation was
calibrated, detection limits were determined, samples were analyzed following published
procedures, and data were examined for accuracy and statistically analyzed. These procedures are
explained in the following sections.
8.4.1 Calibration Procedures and HPLC System Performance
The data quality objectives used for the carbonyl option program are given in Table 8-1.
Initial and daily calibration and other system performance criteria are given in this table, along
with the frequency, acceptance criteria, and corrective action.
The HPLC was calibrated from 0.5 to 20 ug/ml nominal concentration of the derivatized
targeted compounds contained in a solution of acetonitrile. The calibration curve consisted of
five concentration levels between 0.5 and 20 ng/ml, and each was analyzed in replicate. A
standard linear regression analysis was performed on the data for each analyte with the acceptance
criteria being that the correlation coefficient must be greater than or equal to 0.995 and the
relative error for each calibration level against the calibration curve within 20 percent. A
summary of the calibration curve information is given in Table 8-2.
As a QC procedure on the analytical results for all of the quantitated analytes, a second
source QC (SSQC) sample solution containing 11 target carbonyl compounds at a known
concentration was obtained from the Radian Austin, TX office. The following SSQC samples
were analyzed after every 10 samples:
Formaldehyde;
Acetaldehyde;

8.4.2 Detection Limits
Instrument detection limits are given in Table 8-3 for the target carbonyl compounds in
this study. The detection limits were determined by performing nine replicate analyses of a
standard that was half the concentration of the lowest calibration standard, which follows the
method listed in the Federal Register, Appendix B, Part 136.7
8.4.3 Sample Analysis
The analytical procedures for carbonyls are given below. Sample preparation and analyses
were performed at the Radian RTF laboratory. The preparation procedures of the cartridge
samples are as follows:
• Remove cartridge from its shipping container.
• Attach cartridge to the end of a 10-mL luer-lock glass syringe, with the plunger
removed.
• Add 4 milliliters of HPLC-grade acetonitrile to the syringe and catch drainage in a
graduated glass centrifuge tube.
• After the syringe has finished draining, add acetonitrile to the graduated centrifuge
tube until the total volume is 4 mL, and mix the solution.
• Transfer the solution in the graduated centrifuge tube to a 4-mL glass sample vial
fitted with a Teflon®-lined self-sealing septum.
• Store the vial containing the solution in a refrigerator until analysis.

For the analysis, 25 //I samples are injected with an automatic sampling injector. Compound
separation is accomplished using a 25 cm x 4.6 mm CIS 5-micron particle size analytical HPLC
column. Output signals from a multi-wavelength ultraviolet (UV) detector are collected for
40 minutes at 360 nanometers (nm).
Chromatographic peaks for targeted compounds were determined by retention time, the
area of the integrated peak, and concentrations calculated using calibration curves.
Target carbonyl compounds detected were formaldehyde, acetone, acetaldehyde, acrolein,
propionaldehyde, crotonaldehyde, butyraldehyde, isobutyraldehyde, benzaldehyde,
isovaleraldehyde, valeraldehyde, ortho-, meta-, and para-tolualdehyde, hexanaldehyde, and 2,5-
dimethylbenzaldehyde. All measured concentrations were reported in ppbv. The results for any
field blanks were also reported in ppbv, assumed using the same sample volume as the
accompanying samples.
One trip blank cartridge from each site was analyzed for the target carbonyl analytes. The
carbonyl sample results presented in this report are not blank corrected.
8.4.4 Data Reduction and Data Validation
A Perkin-Elmer Nelson® Turbochrom Chromatography Data System consisting of a
900 Series Intelligent Interface and a PC system containing the Turbochrom software was used to
acquire, integrate, and store the analytical data. A chromatogram and area count report are
printed for each analysis. Electronic copies of the data were stored on 1.44 Mb disks, and a
compressed backup disk was also made.
The data were processed using the Turbochrom software. This software contains
retention time information for all compounds of interest and applicable response factors required
to process the data files. The analyst confirmed the proper peak identifications and
quantifications. A preliminary report was generated containing the peaks identified and the
quantitations based on the response factors.
850-008-03-07/cah

-------
A data reviewer compared the report to the chromatogram to check for items which may
have been overlooked by the analyst. A final report was processed and reviewed for
completeness. Final report versions containing information on all quantitated peaks were printed
and filed with the analysis chromatogram printout and preliminary report. Electronic copies of all
reports were also kept on file.

9.0 STATISTICS AND DATA CHARACTERIZATION PROCEDURES
Statistical parameters calculated for all data included maximum, minimum, median, and
mean concentrations. Standard deviation, skewness, and kurtosis were also calculated. In
addition, the Shapiro-Wilk statistic was used to test the normality of the NMOC base program
data. Duplicate and duplicate/replicate data for a given sample date were averaged and
considered as one sample. Non-detect results were treated as missing values.
Standard deviation is the square root of the variance and is often written as a. Standard
deviation provides information concerning the variability of the data in the same units as the data.
The larger the standard deviation, the more variable the data; the smaller the standard deviation,
the less variable the data.
Skewness, kurtosis, and the Shapiro-Wilk statistic are all values which measure the
normality of a data distribution. Skewness is an indication of the symmetry of the data. Data
from a normal distribution have a skewness value of zero. Normal distribution, also often referred
to as Gaussian distributions, results from the random scaner of data bout some true value, often
represented as the mean. If some effect aside from randomness is acting on the data, the resulting
distribution will be nonnormal. Skewness values which depart significantly from zero indicate
nonnormal distributions. Skewness values greater than zero apply to distributions having a longer
tail to the right.
Kurtosis is another method of determining if a distribution is normal or nonnormal. A
population which is normally distributed would have a kurtosis value of 3.0, whereas a
distribution more peaked or pointed would have a value greater than 3.0. All kurtosis values
presented in this report are zero centered, meaning that 3.0 has been subtracted from the fourth
moment to give a reported kurtosis of 0.0 for a normal distribution. The Shapiro-Wilk test was
conducted on only the NMOC base program and is discussed in detail in the following section.

9.1 Statistics: NMOC Base Program
Data obtained from the 1994 NMOC program were analyzed statistically for various
parameters. Values for the arithmetic averages of the NMOC concentrations at each site, as well
as the standard deviation, skewness, kurtosis, and the Shapiro-Wilk statistic are presented.
Results are summarized in Table 9-1.
Three NMOC base sites participated in the 1994 NMOC program: Long Island, NY
(LINY) and Newark and Plainfield, NJ (NWNJ and PLNJ, respectively). Sample collection for
the program occurred from 6:00 a.m. through 9:00 a.m. local time, Monday through Friday from
July 6 to October 31, 1994. During this period, a total of 268 samples were collected, including
27 duplicate samples. Analytical results from each of the sites are contained in Appendix B.
The NMOC data for the summer of 1994 are partitioned in Table 2-11 into groups that
correspond to monthly intervals. For this time period, the monthly concentration means and
medians of the NMOC sites roughly parallel one another, the lone exception occurring in August.
The August value for the median decreases slightly from July, whereas the value of the mean
concentration has increased slightly from the July value. Entering into September, both median
and mean decrease from the August values. A dramatic increase in both median and mean is
observed in the month of October, although it is unclear why this should occur. In addition, the
data become increasingly variable near the end of the program, and again, the reason is unclear.
The effect is readily apparent in Figures 9-1 to 9-3, although the variability for LINY is less
extreme than that for PLNJ and NWNJ. Results by individual analysis channel have been
examined and the channel has no, or only very minimal, effect on the detected level of NMOC.
Overall, PLNJ was found to have the highest mean concentration level of NMOC
(0.663 ppmC), followed by NWNJ (0.641 ppmC) and LINY (0.451 ppmC). Maximum
concentrations were found to also follow this trend: PLNJ, 2.524 ppmC; NWNJ, 2.508 ppmC;
and LINJ, 1.465 ppmC. The largest standard deviation of concentration was 0.539 for PLNJ, and
the mean concentration would often be presented as 0.663 ± 0.539 ppmC. PLNJ has the highest

standard deviation indicated that the NMOC sample concentrations collected from PLNJ over the
course of the program varied over a wider range than did those of NWNJ (a= 0.397) or LINJ
(a= 0.292).
The overall skewness value of 1.979 for the NMOC base sites indicates that the
distribution of the data is not normal, and is therefore being influenced by some external factor or
factors. The overall kurtosis value of 4.893 for the NMOC base sites indicates that the
distribution of the data is not normal. Zero centered kurtosis values greater than 0.0 indicate a
more peaked distribution than a normal distribution.
The Shapiro-Wilk statistic (W) tests the normality of a data set and ranges in value from
zero to one. The closer this value is to one, the better the fit of the data to normality. The overall
value of Wfor the NMOC base sites is 0.810 and indicates that the data is nonnormally
distributed.
Stem-and-leaf plots are often used to provide a graphic representation of a distribution.
Figure 9-4 gives a stem-and-leaf plot of the 1994 NMOC data along with related statistics. It is
immediately apparent when viewing Figure 9-4 that the NMOC data is nonnormally distributed.
The plot shows the actual NMOC concentration truncated to two decimal points. The digits on
the left of the vertical open space are called stems and those to the right are called leaves. The
data are sorted from the smallest value at the top of the figure to largest at the bottom. The
minimum NMOC value measured was 0.055 ppmC, and is shown as "0 5" on the first row at the
top of the plot. The maximum NMOC concentration measured was 2.524 ppmC, and is shown as
"25 0 2" in the bottom row of the chart (0 indicates that the second highest reading was
2.50 ppmC). The plot shows 223 leaves, one for each site datum in the 1994 NMOC program.
The H's to the left of the plot locate the seam and leaf for the upper and lower hinges, and the M
locates the seam and leaf for the median. The median separates the sorted NMOC concentrations
into two equal halves, while the hinges (or quartiles) separate each half into halves. The H
spread, or interquartile range, is the difference between the NMOC values of the two hinges.
These values provide us with a measure of dispersion if the median is used as a measure of central
tendency. Fifty percent of the data lie within the H spread.

-------
Statistics shown for NMOC in Figure 9-4 are the number of cases, minimum value,
maximum value, mean value, median value, standard deviation, standard error, skewness,
kurtosis, and the two hinges. Each NMOC determination is the average of two or three injections
of the site samples. In the case of replicates, each NMOC determination is the average of the
original and repeated analysis concentrations. In the case of duplicates, the NMOC sample
determinations were averaged to represent the NMOC concentration for the sample date.
The standard error is the standard deviation divided by the square root of the number of
cases. This value allows comparison between standard deviations of different sample sizes, much
as percentages allow comparisons to be made between items or groups of different sizes.
A positive value for skewness characterizes a tail to the right of the mean value. A normal
Gaussian distribution has a skewness of zero. The skewness of 1.979 for the 1994 NMOC data
suggests a nonnormal frequency distribution. In addition, the high value for kurtosis (zero
centered) of 4.823 indicates a substantial deviation from normal distribution.
Figure 9-5 is a stem-and-leaf plot of the natural logarithms of the 1994 NMOC data. This
ln(NMOC), or LNMOC, plot shows a very nearly symmetrical distribution with a skewness of
0.055. The kurtosis of 0.044 indicates a distribution just slightly more pointed than a normal
distribution.
The shapes of the two stem-and-leaf plots suggest that the 1994 NMOC data re present as
a lognormal distribution, as has generally been found to be the case for ambient air studies.
Table 9-2 summarizes the LNMOC data using the definitions that characterize a lognormal
distribution, overall and by site. MU (p) and SIGMA (a) are the mean and standard deviation
respectively, of the logarithm of NMOC to the base e. These values represent the mean of the
logarithm of NMOC and the standard deviation of the logarithm of NMOC in units of
log(NMOC).
The geometric mean is e raised to the power MU (e^ and the geometric standard
deviation is e raised to the power SIGMA (e°). These functions provide information for

lognormal functions which is similar to that provided by the mean and standard deviation for
arithmetic functions, such as normal distributions.
The mode is the most frequently occurring NMOC value for a continuous probability
distribution function. This value indicates which value of NMOC concentration appears most
often in the database.
The above data suggest that the NMOC data fit a lognormal distribution, rather than a
normal distribution. This reflects that the majority of the data points are small values, which some
extraneous large values. To properly statistically analyze the NMOC base data, lognormal
functions should be used, such as the geometric mean rather than the arithmetic mean. However,
due to the added complexity of performing the calculations, arithmetic functions have been used
in data analysis through this report. The arithmetic and geometric values usually exhibit good
agreement.
9.2 Statistics: Speciated NMOC Base and Option Program
Data obtained from the 1994 Speciated NMOC program were analyzed statistically for
various parameters. Summary data for all Speciated NMOC base sites are contained in Table 9-3.
Summary data for the NMOC sites which chose the speciated NMOC option (LINY, NWNJ, and
PLNJ) are contained in Table 9-4. The number of cases in which a given compound was detected
(out of 394 analyses) is presented, along with the frequency percent. Minimum and maximum
concentrations are listed, as are the medium and average concentrations and the standard
deviation. Finally, the skewness and kurtosis values for all of the data points for each compound
are included.
A total of 439 samples, included 45 duplicate samples, were collected during the sampling
period from the five Speciated NMOC base sites. Seventy-eight hydrocarbons were quantified
during analysis. Summary data for each of the individual sites involved in the Speciated NMOC
base study are contained in Appendix E.

-------
The overall percent frequency of occurrence for the 78 target compounds ranged from a
low of 1.02% (indicative of 4 detects) for the acetylene/ethane coeluting pair and isobutene, to a
high of 99.75% (393 detects) for benzene, isobutane, isopentane, propane, and toluene. None of
the 78 target hydrocarbons was found to be entirely present or entirely absent, although some
were present in 100% or 0% of all samples from specific sites. Overall average concentrations
ranged from a low of 0.464 ppbC for 1-tridecene, to a high of 28.723 ppbC for isopentane. The
highest level of a target compound encountered was 3370.75 ppbC for n-hexane at EPTX. The
largest standard deviation of concentration for the NMOC Base program, was 171.62 for
n-hexane.
Skewness values for the overall data ranged from 0.134 for acetylene/ethane, to 19.591
for n-hexane. A normal Gaussian distribution has a skewness of zero. A positive value for
skewness characterizes a tail to the right of the mean value. Kurtosis values ranged from -3.484
for acetylene/ethane, to 384.348 for 2-methylpentane. The general trend evident here is for
nonnormal distributions which tail to the right.
In addition to the five base sites involved in the Speciated NMOC study, three NMOC
base sites (LINY, NWNJ, and PLNJ) chose the Speciated NMOC option to the NMOC base
program and had a limited number of their NMOC samples speciated using the same procedures
as the Speciated NMOC base program. A total of 26 samples were analyzed and summary data
for the option are contained in Table 9-4. Summary data for each of the individual sites that were
involved are included in Appendix C.
For the three option sites the overall frequency percent of detection of the 78 target
chemicals ranged from a low of 3.9% (1 detect) for 2-ethyl-l-butene and isobutene, to a high of
100% for 38 different compounds. Overall detected average concentrations ranged from a low of
0.33 ppbC for w-tridecene, to a high of 35.00 ppbC for toluene. The highest level of a target
compound encountered was 229.05 ppbC for acetylene at PLNJ. The largest standard deviation
of concentration for the speciated option the NMOC base program was 47.56 for acetylene.

-------
Skewness values for the overall data ranged from 0.555 for 2-methylpentane, to 4.417 for
1-pentene. These positive values for skewness characterize a tail to the right of the mean value.
Kurtosis values ranged from -2.048 for propyne, to 20.363 for 1-pentene. The general trend is
nonnormal distributions which tail to the right.
9.3 Statistics: 3-Hour Tories Option
Data obtained from the toxics option of the 1994 NMOC and Speciated NMOC programs
were analyzed statistically for various parameters. Table 9-5 summarizes the combined data from
all sites and indicates the number of cases in which a given toxic compound was detected (out of
40 analyses), along with the frequency percent. Also listed are the maximum, minimum, median,
and average concentrations for each of the 38 toxics of interest. Calculated values for the
standard deviation, skewness, and kurtosis are presented. Appendix D contains the same data
broken down by individual sites.
Two NMOC (PLNJ and NWNJ) and three Speciated NMOC (B1AL, B2AL, and B3AL)
base sites chose the toxics option as part of their program. Nine of the samples collected at each
site were used. Of the nine samples, one pair was a duplicate which was analyzed in replicate. A
total of 38 compound were targeted.
The frequency percent of detection of the toxics compounds given in Table 9-5 ranged
from 0% for chloroprene, bromochloromethane, bromodichloromethane, c/s-l,3-dichloropropene,
froHS-l,3-dichloropropene, 1,1,2-trichloroethane, and dibromochloromethane, to 100% for
propylene, chloromethane, methylene chloride, chloroform, 1,1,1-trichloroethane, benzene,
carbon tetrachloride, toluene, tetrachloroethylene, ethylbenzene, m- andp-xylene, styrene, and
o-xylene. Average concentrations ranged from 0.01 ppbv for 1,1-dichloroethane, to 13.16 ppbv
for acetylene. The highest level encountered was 197.78 ppbv for acetylene at PLNJ. The largest
standard deviation of concentration, that for acetylene, was calculated to be 33.65 ppbv.
Overall skewness values for the 38 toxics compounds ranged from a low of 0.192 for
frons-l,2-dichloroethylene, to a high of 4.892 for methylene chloride, likely indicative of a

lognormal distribution. Kurtosis values ranged from a low of-3.333 for 1,1-dichloroethane,
indicating a less pointed or peaked distribution than normal, to a high of 28.983 for
tetrachloroethylene, indicative of a distribution considerably more pointed or peaked than normal.
9.4 Statistics: Carbonyl Option
Data obtained from the carbonyl sampling option of the 1994 NMOC program were
analyzed statistically for various parameters. Tables 9-6 and 9-7 summarize data from the two
sites involved in the study (NWNJ and PLNJ) and contain the maximum, minimum, and mean
concentrations found for each of the 16 carbonyls of interest. Also included are the values for the
standard deviation of the concentrations and frequency of occurrence of detectable levels of each
compound. The statistical results for the carbonyl option should be used with caution since
sampling populations were small.
Two NMOC base sites participated in the 1994 carbonyl option program (PLNJ and
NWNJ). Ten or eleven carbonyl sample cartridges, including a duplicate pair, were selected from
each site for sample analysis. Samples were collected concurrently with the NMOC canister
sample through the use of a separate sampling system. Sixteen carbonyl compounds were
targeted for analysis.
For NWNJ, the mean concentrations of the carbonyl compounds ranged from 0.14 ppbv
for valeraldehyde, to a high of 5.64 ppbv for formaldehyde (isovaleraldehyde was not detected).
For PLNJ, the values ranged from 0.27 ppbv for hexanaldehyde, up to 5.28 ppbv for acetone
(non-detects were encountered for acrolein, isovaleraldehyde, valeraldehyde, tolualdehydes, and
2,5-dimethylbenzaldehyde). Frequency of occurrence for both sites ranged from 0% to
100 percent. Formaldehyde, acetaldehyde, acetone, propionaldehyde, and butyr-isobutyraldehyde
were found in 100% of all samples from both sites. Tolualdehydes were detected in all samples
from NWNJ, but in no samples from PLNJ. The highest level detected was 38.22 ppbv for
formaldehyde at NWNJ. The largest standard deviation of concentration, that for formaldehyde
at NWNJ, was 10.91 ppbv.
