QUALITY ASSURANCE PLAN ESTABLISHED FOR PAMS
IN EPA REGIONS I, II, AND III
EPA Regions I, II, and ID have established a quality assurance
(QA) plan for the Photochemical Assessment Monitoring Stations
(PAMS) in their Regions (the Northeast Corridor) which will be
implemented for the upcoming 1993 ozone season. The goal of the
plan is to identify the inter-organizational variability in the PAMS
network in the three Regions, including variability between the
States within each Region and between the Regionally
designated central laboratories (DCL).
Each EPA Regional Office will be responsible for
the QA of PAMS monitoring conducted within its
Region. Each Region will appoint a DCL to conduct
the analytical QA work. Overall PAMS QA coordina-
tion among the three Regions will be the responsibility of
Region n. QA activities during the first year will be
performance-based and focus on accuracy, precision,
and minimization of sample contamination.
Specific activities within each Regional
program include the following:
•	Analysis of cleaned canisters -In May,
July, and September, the Regional DCL
will analyze a cleaned canister blank
provided by each State conducting
monitoring at a Type 2 site.
•	Analysis of collocated/split
samples - The Regional DCL
will analyze a collocated/split
sample taken at each Type 2
site at a frequency of one col-
located/split sample for every six days of monitoring.
•	Round-robin analysis of standards - During May, July, and
September, each State conducting monitoring at a Type 2 site will
analyze a round-robin sample prepared by EPA's Atmospheric
Research and Exposure Assessment Laboratory (AREAL) or
Region II.
•	Analysis of State standards - The Regional DCL will analyze a
sample of the calibration standard used by each State conducting
monitoring during the months of May, July, and September.
•	On-site audits - On-site audits of each State's PAMS participat-
ing analytical laboratory and field site will be conducted by the
Region. Region II will offer its services for QA consultation and,
if requested and if sufficient travel arrangements can be made, will
participate in such audits.
Specific activities among DCLs for April, June, and August
will include the following:
•	Analysis of cleaned canisters - Each DCL will provide a cleaned
blank canister to the two other DCLs for analysis.
• Analysis of collocated/split samples - Each DCL will
provide a collocated/split sample for analysis by the two
other DCLs.
• Round-robin analysis of standards - Each DCL
will analyze a round-robin sample provided by
AREAL or Region II.
Specific Region II duties include the fol-
lowing:
•	Coordination of the inter-regional portion of the QA
program.
•	Review of data obtained by each DCL and dissemi-
nation of the data to the EPA Regional Offices in
Regions I, II, and HI.
• Coordination of any extra inter-regional exchange of
standards, blanks and samples that may be required in order to
verify problems or as part of corrective action or troubleshooting
actions.
•	Coordination of the PAMS QA effort undertaken by Region I,
II, and III with AREAL and the Office of Air Quality Planning and
Standards.

PM-10 SATURATION
MONITORING STUDY
CONDUCTED IN
ASHLAND,KENTUCKY
A PM-10 saturation monitoring field
study sponsored by EPA's Office of Air Qual-
ity Planning and Standards, Monitoring and
Reports Branch, in cooperation with EPA
Region IV, was conducted in the Ashland,
Kentucky area during July and August, 1992.
The area encompassed by the study extends
across three States and EPA Regions (Ken-
tucky, Region IV; Ohio, Region V; and West
Virginia, Region ID). Personnel from each
State and Region provided assistance in the
design and conduct of the study. In addition,
the Ashland Regional Office of the Kentucky
Division of Air Quality provided extensive
support throughout the study.
The major purpose of the PM-10 moni-
toring project was to evaluate the use of por-
table PM-10 monitors in examining thepoten-
tial for exceedances of the national ambient
air quality standards (NAAQS) in the Ashland
area and to make recommendations for opti-
mizing permanent monitoring locations. In
designing the saturation study, emphasis was
placed on identifying potential high concen-
tration areas and characterizing the overall
spatial distribution of PM-10 concentrations
in the area. The final monitoring network
design included spatial coverage of the indus-
trial sources located in the Ashland area. A
total of 19 sites were included in the network.
Most were elevated- and base-level monitor-
ing locations designed to cover air quality
impacts from stack and ground level fugitive
emissions. A majority of the sites were se-
lected to represent expected maximum con-
centrations from point sources, several sites
were chosen to represent population exposure
in areas of citizen complaints, and one site was
chosen to reflect background concentrations.
The spatial scale of representativeness of the
sites ranged from 500 meters to 2 kilometers
and included sites not unduly influenced by
nearby sources such as gravel roads, railroad
tracks, or construction activity.
The PM-10 saturation samplers used in
the study were designed, built, and modified
by the Lane County Regional Air Pollution
Authority (Springfield, Oregon) to include ret-
rofit changes. The samplers were battery oper-
ated and designed to be mounted on a utility
pole. The inlet of the sampler provides a PM-
10 particle size cut point at a flow rate of 5 liters
per minute (1pm). Sampling periods were
approximately 24 hours, and the sampler in-
cluded a programmable time and an elapsed
time meter to record the actual sampling time
interval. Daily sampling, including weekends,
was conducted from July 11, 1992 through
August 18,1992; historically, the highest par-
ticulate concentrations were recorded during
this time period. The sample filters (quartz and
some Teflon®) were changed between 4 p.m.
and 8 p.m. each day. Quality assurance (QA)
and quality control (QC) procedures were de-
veloped and implemented throughout the study
period. The QA/QC provisions included col-
located sites, duplicate weighings, field blanks,
calibrations, audits, and data validation and
flagging. In addition to the PM-10 measure-
ments, hourly wind speed, wind direction, and
temperature measurements were recorded at
three meteorological stations in the study area.
The goal of the study was to collect 30
samples, of which at least 85 percent would be
valid. Total valid data capture over the three
month study period, however, was slightly
greater than 81 percent Overall operational
precision based on two collocated sites was
less than 15 percent at one site and 40 to 50
percent at the second site. The precision at
the second site improved significantly (to
less than 15 percent) after actions were taken
to correct quartz filter damage problems.
Analytical precision, estimated from labora-
tory reweighings of clean and exposed filters,
was within 0.015 milligrams for both quartz
and Teflon® filters. Data accuracy was esti-
mated based on flow audits (field operational
accuracy)and comparisons between data from
the portable monitors and collocated refer-
ence monitors. All sampler flow audits re-
sulted in flow rates within +/-10 percent of
thedesiredflowof51pm. After the corrective
actions were taken, the portable samplers
compared very favorably [i.e.,aslightlyposi-
tive bias (2 to 5 iig/mJ) compared to the
reference samplers]. Filter weighing differ-
ences between two laboratories showed a
positive bias in one of the laboratories result-
ing in an expected concentration difference
of about 2 ng/m3 for Teflon* filters and 4 pg/
m5 for quartz filters. The limit of detection
based on analysis of blanks was approxi-
mately 12 ng/m3 for both Teflon* and quartz
filters.

I REGIONAL CORNER
-REGION I-
During January and February of 1993, the Massachusetts State
Department of Environmental Protection performed a carbon monox-
ide (CO) saturation study in Boston, around the site at which previous
violations had been monitored. No 8-hour CO levels greater than 5.5
ppm were detected. The State may use the results of the study for
demonstration of attainment
During the same time period, CO saturation studies were also
performed at three other street intersections. These studies were
performed for the Massachusetts Department of Public Works to
provide baseline data for their Central Artery Reconstruction Project.
This roadway improvement project is planned to continue for 10 years,
and will incorporate PM-10 and CO monitoring studies throughout the
life of the project.
The Maine Department of Environmental Protection (DEP) is
investigating the need for a study to assess the effects of wood smoke
in river valleys. EPA has identified this as a potential problem area, and
the Maine DEP is considering a PM-10 saturation study to determine
if a problem truly exists. The DEP's data collection goal is to have 20
valid sampling days.
The Region I Environmental Services Division is planning to
operate a PM-10 saturation study in Vermont during the summer of
1993. An emissions inventory performed by EPA Headquarters
suggests that Washington County, Vermont contains a number of
potential PM-10 sources and that further study of the area may be
warranted. The county contains approximately 30 small and 5 large
sources, primarily rock quarries. Region I plans to set up a monitoring
network for approximately two months this summer, with up to 15
samplers and a goal of collecting 20 days worth of valid data.
-REGION m-
Region III, in cooperation with EPA's Office of Research and
Development (ORD), is performing an acid aerosol study in Pitts-
burgh, Pennsylvania during June, July, and August of this year. The
program used denuder samplers. Analyses by ion chromatography
were performed by the city of Pittsburgh, with advice from the Harvard
School of Medicine.
Several CO saturation studies were conducted in Region in. Two
studies were performed in Baltimore and Bladensburg, Maryland,
during December 1992 and January 1993. Reports from these studies
are in preparation.
A CO study in Washington, DC street canyons is now in its second
year. In the first year, the city was scanned for potential high CO sites.
Similar studies may be conducted this year in Richmond, Virginia,and
Harrisburg, Pennsylvania.
-REGION IV-
The State of North Carolina is planning to implement a network
with goals similar to the Photochemical Assessment Monitoring
Stations (PAMS), although no PAMS are required in the State. The
network is to include sites in Raleigh-Durham, Charlotte, Greensboro,
and Winston-Salem. Extensive ambient air monitoring data are
needed to "fine tune" the Urban Airshed Model (UAM) used for this
study. A network of 11 to 15 UAM multiple pollutant monitoring sites
is planned to be initiated in 1993 and expanded to approximately 25
sites in 1994.
EPA, the eight States surrounding the southern Appalachians
(AL, G A, KY, NC, SC, TN, VA, and WV), the National Park Service,
and the Forest Service have agreed to work on a cooperative assess-
ment to better define and find solutions to air pollution problems that
have the potential to affect federal lands, especially those involving
higher elevation forests and aquatic ecosystems. This program, the
Southern Appalachian Mountain Initiative (S AMI), will involve moni-
toring of sulfates, ozone, nitrates, particulates, and visibility, and will
make use of existing sites where possible, with additional sites to be
added in time. The program is voluntary, with the States leading the
initiative.
PM-10 Saturation Monitoring Study
(continued from page 2)
Considering valid and suspect concentration data, the study
shows a mean of 37 |ig/m3 and a median of 36 |xg/m\ which are well
below the PM-10 24-hour standard of 150 ng/m3. No valid PM-10
concentrations were recorded that exceeded the 24-hour standard. The
maximum value was 135 |ig/m3, and the second highest value was 82
Hg/m3. Figure 1 shows a summary of PM-10 concentrations by site.
Based on results of the study, no changes were recommended to the
existing PM-10 monitoring network in the area. Two of the portable
saturation sampling sites, however, recorded levels higher than exist-
ing PM-10 samplers in the area. Establishing additional PM-10 sites
at the locations of these two sampling sites could improve the network's
ability to record the highest PM-10 levels that may occur in the study
area. For further information on this study, contact Neil Berg, U.S.

Mapping Analysis Used To Assess Adequacy Of PM-10 Monitoring
Network In Harris County, Texas
A recently developed technique for the analysis of ambient
monitoring networks is the use of mapping analysis to provide a cost-
effective method of performing initial reviews. The technique is based
on analyzing maps that plot the locations of monitoring installations
and of major pollutant sources.
Recently, EPA's Region VI sponsored a project to use this
approach to assess the adequacy of the existing PM-10 monitoring
network in Harris County, Texas. The EPA's Office of Air Quality
Planning and Standards (OAQPS) had completed a review of potential
PM-10 sources nationwide. Harris County, Texas was ranked fourth
in the nation for potential major PM-10 sources. The present PM-10
network was established based on the previous total suspended par-
ticulates (TSP) network (established about 12 years ago) and may not
accurately represent the current ambient air quality impacts of major
PM-10 sources in Harris County.
The review consisted of a mapping analysis of monitoring loca-
tions versus source locations and focused on whether the existing
industrial classification (SIC) and facility size with industrial informa-
tion for a particular area obtained from national databases. The
databases used were the AIRS Facility Subsystem (AFS), the U.S.
Department of Commerce's Census of Manufacturing (COM), and
EPA's Facilities and Company Tracking System (FACTS).
Three maps were developed to show the relative locations of PM-
10 monitoring sites and areas of high potential PM-10 impacts in Harris
County. PM-10 impacts were represented differently in each map.
The first map showed source density within each zip code region,
where source density is defined as the total numberof employees in the
zip code region multiplied by the total numberof sources in the zip code
region. The second map showed the aggregate PM-10 impact for each
zip code area, where the PM-10 impact was estimated from analysis of
the source information used in the OAQPS review. The third map
showed estimated PM-10 impacts for individual sources. On each
map, relative PM-10 impacts were represented using color according
to percentile ranking for the county. Zip code areas were ranked for zip

network is representative of point source impacts only. According to
the Texas Air Control Board (TACB), mobile sources make up a much
larger proportion of the total PM-10 burden in the area than point
sources (possibly by as much as a factor of 10); however, point source
impacts are probably responsible for any locally high concentrations.
Maps were prepared, showing the location of the existing PM-10
monitoring network relative to different representations of the poten-
tial PM-10 impact from industrial sources in the area. For the purpose
of the mapping analysis, PM-10 impact was defined as the estimated
ground level impact from industrial sources. The impact estimates
were not derived from an emission inventory. Rather, the estimates
were obtained by associating "typical" impacts for a given standard
codes in Harris County containing sources. Individual source loca-
tions were ranked within the total population of sources used in the
study. The use of percentiles presented a clearer picture of the relative
impact estimated for one area compared to another and avoided using
possibly misleading units (e.g., tpy).
The first, second, and third maps (in order) deliver increasing
information content with a corresponding decrease in the confidence
level of the representation; however, each map provides a useful point
of view. The source density map identifies areas where there is a
concentration of industry with potential to emit PM-10, but does not
account for PM-10 impacts. The accuracy of the source density

Mapping Analysis
(continued from page 4)
numbers depends only on the accuracy of the database used. The map
showing PM-10 impact by zip code identifies concentrations of
industry and estimates relative PM-10 impacts. The accuracy of the
PM-10 impactestimates depends on acomplex association of informa-
tion from multiple databases involving many assumptions. The map
showing estimated PM-10 impacts for individual source locations
provides the most detailed information; however, the level of confi-
dence in the impact estimates for individual sources is low. This map
should be viewed primarily as identifying source locations, and only
secondarily as providing impact estimates.
Each map also includes a table summarizing the historical PM-10
concentrations measured by the existing network. The summary table
gives the highest quarterly median and maximum concentration re-
corded during the period from the first quarter of 1988 through the
second quarter of 1992 at each site. This provides a rough, but useful,
characterization of the average and maximum concentrations that
might be expected at each station.
Along with the maps, a report was prepared, containing details of
the methods used to develop the maps and recommendations based on
the results of the mapping study. In addition to the maps, several other
factors were considered in assessing the existing network. Available
meteorological data were used to determine the predominant wind
direction accounting for seasonal and diurnal differences. Available
related information was also reviewed for further information on PM-
10 impacts in the area. This information included existing modeling
study reports, upset information, and citizen complaint information.
Due to the uncertainties in estimating source strength from the
available data, recommendations based on a mapping analysis are
general to a degree that depends on the quality of the data used to
prepare the maps. While the maps point to areas where the highest PM-
10 impacts from industrial sources are located, the mapping analysis
cannot determine whether these areas have sufficient PM-10 emis-
sions to pose a threat to the NAAQS standard given the prevailing
dispersion conditions. Further analysis based on more detailed infor-
mation on the nature and extent of PM-10 emissions from individual
sources is needed to support decisions to add or relocate PM-10
monitors in the network. This could be acquired through dispersion
modeling or saturation monitoring.
The mapping analysis showed that the existing PM-10 network
does not represent all of the areas in Harris County with the highest
potential PM-10 impacts from industrial sources. On the map showing
PM-10 impact by zip code, there are 8 zip code areas with an estimated
PM-10 impact above the 90th percentile for the county. The four high
impact areas located nearest to the city of Houston, and in the most
populated areas, are generally covered by theexisting NAMS/SLAMS
maximum concentration sites. The remaining four areas with the
highest potential impacts are located further from the city of Houston,
primarily in the ship channel area. This region is not represented by the
existing network.
The recommendation of the mapping analysis was for perfor-
mance of a more detailed network review to assess the need for
additional maximum impact sites in the ship channel area and possible
relocation of the maximum concentration sites. The mapping ap-
proach used in the initial review of the Harris County PM-10 network
provided useful information at relatively low cost (compared to
modeling or saturation monitoring) and supplied a basis for more
refined analyses.

USEFUL AMTIC BBS TIPS
The AMTIC Bulletin Board System (BBS) is intended to serve
as a source of information, including useful documents and current
news, and as a forum for discussing ambient monitoring issues. This
column features several tips and hints to make using the BBS easier
and more productive. Most of the information provided in this article
can be found in the TTN users' manual, which is also available for
download from the top menu under system utilities.
Screen Printing .TXT files:
Files with the suffix .TXT are in ASCII format and are screen
readable. To print them to your screen, type
"P"[space]" 1"[space]"filename.txt" at the prompt For example, to
print the file TRAINING.TXT to the screen, you would enter the
following at the prompt:
P 1 TRAINING.TXT (ENTER)
Using the (S) command:
Many of the .TXT files available on this BBS are quite long. To exit
a .TXT file without having to scroll through every page, type the letter
(S). This command also works in several other areas of the BBS (the
Alerts, for instance).
Using Help:
Don't forget that help files describing how to download files are
available, and are accessed by typing (H) at the prompt when you are
in a file download area.
.ZIP and ARC files:
Many of the files available to be downloaded from the BBS have been
compressed to save disk space and download time. These com-
pressed files may be identified by the suffixes ZIP or .ARC appended
to their filenames. These files are NOT screen readable, and must be
downloaded and decompressed before they can be used. Dearchiving
programs are available on the main TIN menu under (1) System
Utilities, then (A)rchivers/Dearchivers. A text file with more infor-
mation on how to use the programs is also located there.
~~~~E-Mail Hints^"
Including a File in an E-Mail Message:
The (F)ile option allows you to enclose a file in an E-Mail message.
To do this, type (F) when you are given options after entering your
message text. You will then be prompted for the filename (the name
you want the file IN THE MESSAGE to have) and the file transfer
protocol you wish to use.
Next, you must set the same file transfer protocol on your terminal
(this varies, dependingon what software you are using; in PROCOMM,
for example, hit the Page Up key, and then choose a transferprotocol).
You will then be asked to enter the location and name of the file to be
included (for example, C:\MYDIR\MYFILE.TXT). After the upload
Page 6
is complete, type (S) for send, and the message will be sent with the
enclosed file.
When receiving a message with an enclosed file, select (E)nclosure
from the menu, and follow a procedure similar to the one described
above to set file transfer protocols on the BBS and at your terminal.
Using Your Cubbyhole:
When reading messages on one of the public message boards, one of
the options you are given at the bottom of the screen is (Qubbyhole.
This allows you to place a copy of the mail message in your own
personal cubbyhole. By doing this, you may keep copies of any
messages that are of special interest to you and access them easily
without hunting them down on the public message boards every time
you wish to read them. To read the messages in your cubbyhole, look
under "<5>Read Cubbyhole Messages" on the top menu of the TTN.
Sending Carbon Copies of E-Mail Messages:
To send a copy of an E-Mail message to several people (other than the
person it is addressed to), include the following as the FIRST line in
your message text:
cc: Namel ,Name2,...,etc.
Where Namel,Name2„.„etc. are the people you want copies sent to
(be sure to include a space after "cc:").
Using Read (Reverse and Read (N)ew:
When using one of the public message boards, you will be offered
several options. Rather than starting at the beginning and reading all
of the old messages again, use the (N)ew option to read messages that
have been posted since your last logon to the BBS, or use (Reverse
to start with the most recent message and work backwards.

EPA Coordinates 1993-1994 NMOC and PAMS Air Monitoring
Programs with State and Local Agencies
EPA's Office of Air Quality Planning and
Standards (OAQPS) is coordinating two 1993-
1994 ambient air monitoring programs with
those State and local agencies wishing to
participate. The programs are (1) the
Nonmethane Organic Compound (NMOC)
PROGRAM and (2) the Photochemical As-
sessment Monitoring Stations (PAMS) PRO-
GRAM. The NMOC PROGRAM is de-
signed to provide input monitoring data for
those ozone areas designated as marginal or
moderate that are able to use the Empirical
Kinetic Modeling Approach (EKMA). The
PAMS PROGRAM is designed to provide
data for those ozone areas designated as seri-
ous, severe, or extreme that are likely to use
the Urban Airshed Model (UAM). Several
options within each of these two PROGRAMS
are available, and the price per sampling site
varies with the options selected.
The NMOC PROGRAM includes two
base programs and four optional programs.
One of the base NMOC programs, the NMOC
Program, includes 82 days of3-hour weekday
canister sampling and analysis using EPA
Compendium Method TO-12 (standard total
organics). The second base program, the
Speciated NMOC Program, includes all items
in the first base program except that chemical
speciation is substituted for Method TO-12 in
order to provide chemical bond four (CB-4)
inputs to Regional dispersion models.
Options included undertheNMOC PRO-
GRAM include (1) a speciated NMOC canis-
ter sampling and analysis program for a total
of 10 analyses; (2) a 3-hour canister toxics
option for a total of 10 analyses; (3) a 3-hour
cartridge sampling carbonyl option for a total
of 13 analyses; and (4) an AIRS/AQS speci-
ated NMOC data entry option. The options
require participation in either one of the base
NMOC programs.
The PAMS PROGRAM consists of two
base programs and one optional program.
One of the base PAMS programs is the PAMS
VOC Program, which consists of 255 sam-
pling events. The events include 3-hour
samples every 3 days for 3 months, and one
24-hour sample every 6 days for 3 months.
Analysis is by gaschromatography (GC)/dual
flame ionization detector (FID) for 56 target
hydrocarbons and total NMOC. The second
base program is the PAMS Carbonyl Pro-
gram, which includes 240 sampling events
(eight 3-hour samples every 3 days for 3
months). Sampling is conducted using
dinitrophenylhydrazine (DNPH) cartridges,
and analysis is by high-performance liquid
chromatography (HPLC) Compendium
Method Tail.

grams, contact Neil Berg.U.S. EPA, Monitor-
ing and Reports Branch (MD-14), RTP, NC
