PREFACE
The National Air Surveillance Network (NASN) is a nationwide
network of air pollution monitors used by the Environmental
Protection Agency (EPA) for trends monitorins* EPA Region IV
assumed the responsibility for that portion of the national
program located within its Jurisdiction on January I* 1974.
In the absence of a formal standard operating procedure and
schedules for calibration* preventative maintenance* and
documentation* Region IV undertook this task as part of its
quality assurance program* This Standard Operating Procedure is
written* as nearly as possible* in a stepwise manner with a
minimum of technical terms* Each portion of the procedure is
explained in detail only once*
The purpose of this Standard Operating Procedure is to
enable a high school graduate to have a two day general
familiarization session and then use this document to operate the
NASN* To ensure the technical accuracy* clarity* and
completeness* these procedures have been tested* modified* and
retested over an 18month period* These procedures are not
intended to be final* They will be modified as new methods and
better information become available* At present* they are
written for the General itetal Works 1 hi vol* Dayton timer*
Research Appliance Corporation bubblers* and Dresser Industry's
positive displacement meter*
This manual Is not all Inclusive in that it does not include
the laboratory or data support group activities in a stepwise
manner* Instead* these activities are shown where there is an
interface with the monitoring and field support activity* The
frontispiece is a flow diagram of the entire NASN activity as it
relates to the monitoring and field support activity*

Timer Wiring
Most Dayton timers come with three cords* The male plug is
on the main power cord* The other cords are for power to the
samplers to be controlled* Power to one cord is normally ON
while the other is normally OFF. For NA.SN use* this arrangement
must be modified- CAUTION! All wiring changes must be done with
the timer unplugged*
Step *I- Remove the lead from point 3B and connect it at point
3A with the other black lead* See Figure 2*

Timer Calibration
This procedure ia perforated before each timer is shipped
into the field and again after it is returned from the field*
Timers are calibrated at least annually* Calibration data are
recorded in the Timer Calibration Log* See Figure 4*
S±fia_£l: Plug a correctly wired timer into an electrical outlet
on the test bench* ouuet
Stjg£2* Set the timer to the correct time*
StCP #3* Set the ON and OFF time trippers for a 24-hour test
period*
S*«B /lu« the test ll*ht one of the output plugs and an
elapsed time meter into the other*
StflP #5* Check the system by manually operating the switch ON
and OFF *
StCP ffeJ Allow the system to operate for the 24-hour test period
and determine the elapsed time froa the elapsed time meter*
If the elapsed time is 24 hourst £15 minutes,
the timer is acceptable for field use*
* " ***« elapsed time ia not 24 hours +15
minutes, reject the timer for fisld use*

Barometric Pressure Measurement
This section outlines the procedure for measuring the
barometric pressure with a U. S. Signal Corps type mercurial
barometer*
Steo <1: Adjust the base level of the mercury by turning the
brass calibration screw at the base of the barometer until the
white plastic point Just touches the mercury pool surface* This
is most easily done by watching the reflection of the point in
the surface and bringing the two points together*
Step 02i Adjust the slide to the top of the mercury by rotating
the knob on the right hand side of the tube* The bottom of the
slide should be level with the very top of the mercury* See
Figure 5.
Step 13; Bead the right hand scale at the bottom of the slide to
the nearest whole millimeter (mm)* For exaaple« Figure 5 has a
reading of 710 mm*
Step 04: Read the vernier scale at the one place where the best
matching of lines with the millimeter scale exists* For example,
in Figure 5* this is at the 6 on the vernier scale and is read as
0*6 mm*
Step Calculate the mercury column height by adding the
values obtained in Steps 3 and 4 above*
710* mm from mm scale
0*6 mm from vernier
710*6 mm mercury column height
Step 06: Calculate the absolute barometric pressure by
subtracting 0*8 am from the mercury column height calculated In
Step 05 above*
710*6 mm mercury column height

T* T2
where
Pi = measured pressure
V| = measured volume
Tk - absolute temperature measured in °K
Pj = 760 mm Hg« reference pressure
Tj = 298°K = 25°C; reference temperature
V2 - reference volume
StgP ffl ~ Convert Ti to °K
Case A If T is in °C| convert by adding 273
T ~ 273 = Tr
Case B = If T is in °F» convert by substituting
in the equation:

Particulate Data Handling
The Particulate Becord Sheet Is used by the person who
operates the hi vol to record relevant information* See Figure
25. If the operator fails to record all relevant information or
records incorrect information* a large red "X" is marked by the
NASN coordinator In the top right corner of the Particulate
Record Sheet and the error or omission is circled in red*
Steo 01: Open the envelope and verify that the envelope contains
a hi vol filter In a protective filter holder and a Particulate
Record Sheet*
Step 02: Verify that the number on the hi vol filter is the same
as recorded on the Particulate Record Sheet*
Step 13: Examine the hi vol filter for holes* missing parts* or
tears causing air leaks during sampling* Void filters with these
symptoms* If a filter is torn during removal from the hi vol* it
is still considered a valid sample providing all filter parts are
present*
iten Hf4: Examine the hi vol filter for a clean white margin* 1*6
wide or greater, all of the way around the filter* Void all
VIIters having less than a 1*6 mm margin at any place*
Step ? 5 - Examine the margin for sharpness* If there is not a

Standard Operating Procedure tor
Hi Volume Air Sampler (Hi Vol)
The Hi Vol is an instrument used to collect samples of total
suspended particulate (dirt) in the air* The samples are
collected on an 8" x 10" glass fiber filter* A timer is used to
turn the sampler ON at midnight and allow the sampler to operate
24 hours* The sampling schedule is standardized nationwide so
one sample is collected nationwide once every 12 days on the
same dav. A copy of the sampling schedule is attached*
Materials used in the operation of the Hi Vol consist of a glass
fiber filter for collecting the sample* a ma.nl La. folder foe*
protecting the filter and sample after collection, a Particulate
Becord Sheet for recording information about the Instrument and
the sample collected* and a selfaddressed stamped envelope for
returning the above item* A new supply of these items and
sampling schedule will be provided in November or December*
If a filter from a previous run is on the sampler* start at
Step Al* If the sampler is being set up for the first time or no
filter is on It* start at Step Bl*
Al Locate the ONOFF switch on the lower left hand face of
the timer and turn the hi vol ON to warm up for 5 minutes*
A2 Connect the free end of the rotameter hose to the
nipple at the exhaust (bottom) end of the hi vol in the shelter*
A3 Holding the rotameter vertically* take a reading on the
scale opposite the center of the ball* Turn the hi vol OFF and
record this reading under Stop flowrate on the record sheet*
NOTE: If the ball is stuck at the bottom of the rotameter*
tap gently against the hi vol to free It* Also* notify
the NASN coordinator of this difficulty* If the ball
is at the top of the rotameter and off scale* cover the
rotameter exhaust port at the top of the rotameter
momentarily* This should cause the ball to drop onto
the scale* If it does not turn off the hi vol,
disconnect the rotameter* and notify the NASN
coordinator*
A4 On the particulate Record Sheet record the rotameter
number in the Sampler Serial No* blank* In the Filter No. blank
record the number stamped on the corner of the filter* Beeord
the wind direction in the blank marked direction* Check the
appropriate blocks for wind speed* visibility* sky cover*

Needle Number Assignment
Each needle used in the gas bubbler system is assigned an
identification number which is inscribed permanently into the
needle body* The base of the needle is color coded to identify
which needles are designated for use in SO2 and which are
designated for use in M02 sampling* Once a needle with an
assigned number is destroyed) this is recorded as appropriate in
the S02 or NO2 Needle Log and that same number is assigned to a
new needle*
The numbering system consists of one letter (either S or N)t
a two digit number (from 01 to 99) and one letter (from A to Z)«
There is no difference in the needles used for SO2 or NO2
sampling* However* the needles used for SO2 sampling are
designated with a prefix of S* The needles used for N02 sampling
are designated with a prefix of N* This is an aid to minimize
mix up of needles and Identify when a mix up has occurred*
The needle is assigned a chronological number from 01 to 99*
Due to the lack of space on the needle for infinitely long
numbers* a letter is assigned as a suffix* The first 99 needles
numbered would have the suffix of A; the second 99 needles would
have a suffix of BJ the third 99 needles would have a suffix of
CJ etc*
The needles have a color coded band around the base to
identify to the operator which is an SO2 needle and which is an
NO2 needle* SO2 needles are color coded blue and NO2 needles are
color coded retf*
Step »1: Assign a new or previously discontinued number to a
needle that falls within the flow rate range of 190 to 210
cc/min*
engraver as shown in Figure 31*
Step 03: Place the appropriate colored heat shrink tubing around
the needle base as shown in Figure 31 and shrink in place with a
heat gun*

Bubbler Data Handling
The Gas Sample Record Sheet is used by the person who
operates the g&s bubbler to record relevant information* If the
operator fails to record all relevant information or records
incorrect infomation, a large red "X" is marked by the NASN
coordinator in the top right corner of the Gas Sample Record
Sheet and the error or omission is circled in red*
When the sample returns from the field* it goes first to th
laboratory where the samples are removed and the samples are
logged in* Any discrepancy in the sample or recordkeeping is
noted* If anything is observedf a large red X is placed on the
upper right hand corner of the gas sample record sheet for
ultimate resolving by the NASN coordinator* Next the mailing
block complete with the gas sample record sheet and needles used
on the run are transferred to the NASN coordinator*
Step ll: Open the mailing block and check for the presence of
two needles and the Gas Sample Record Sheet*
Step 02: Verify that the needles in the mailing block are the
same as recorded in the remarks column of the Gas Sample Record
Sheet
Step »3: Measure the flowrate of each needle and record these
flowrates as the ending flowrates in the appropriate needle
calibration book*
Examine the Gas Sample Record Sheet for comments which
may affect the interpretation of the data* or for comments
regarding instrument performance and service required*
Steo #6: Place the needles in a protective cover and place in
the calibrated needle storage area*

Gas Bubbler Standard Operating Procedure
The gas bubbler is an instrument used to collect samples of
gaseous pollutants in the air* The samples are collected by
bubbling air through specific liquid reagents* A timer is used
to turn the sampler ON at midnight and allow the sampler to
operate for 24 hours* The sampling schedule is standardized
nationwide so one sample is collected nationwide once every 12
daysan the same day. A copy of the sampling schedule is
attached* Materials used in the operation of the gas bubbler
consist of sample tubes for collecting the samples* hypodermic
needle for controlling flowrates* a gas sample record sheet for
recording information about the instrument and the sample
collected* and a mailing block for transport of the sample tubes
to and from the site*
A new mailing block will be supplied at least one week
before the sample date* If none is received call the NASN
coordinator, Mr* Jerry Burger¦ persontoperson collect at
404/5462297 to receive a new sample*
If a sample or tube from a previous run is on the sampler*
start at step Al* If the sampler is being set up for the first
time or no sample is on the sampler start at Step Bl*
Step
Al: Locate the ONOFF switch on the lower left face of the
timer and turn the pump ON to check the vacuum and verify flow by
checking for bubbles in the sample tubes*
A2: Record the vacuum gage reading on the Gas Sample Secord
Sheet under "Meter reading END OPEN"*
A3: Clamp the vacuum hose*

CLAMP."
A5: Open the clamp and turn the pump OFF*
A6: Remove the NOz (red) needle from the bubbler and place
it in the return mailing block*
A7: Remove the NO2 sample tube from the bubbler and cover
the two holes with the small caps* Tighten down the caps to
prevent leakage in shipment*
A8: Place the NO2 sample tube in the return mailing block*
A9l Repeat steps A6» 7 and 8 for the SO2 (blue) needle and
sample tube*
AlO: Fill out the meteorological data on the Gas Sample
Record Sheet for the sampling date*
-------
All; Assure that the site location and date is recorded on
the Gas Sample Record Sheet.
A12: Insert the original copy of the Gas Sample Record
Sheet into an empty hole in the mailing block.
A13: Close the mailing block and tighten the wing nuts with
the special wrench provided.
A14: Attach the franked addressed label to the block and
mai I.
Step
Bl; Open the mailing block.
B2: Verify that the block contains two copies of a Gas
Sample Record Sheet with carbon paper* one NO2 sample tube with
flow control needlef and one SO2 sample tube with flow control
needle.
B3: Place the NOj sample tube in the empty space in the
bubbler rack.
B4: Take the two small caps off the holes in the top of the
sample tube.
B5: Attach the accordian tubing tightly to the hole on the
colored side of the tube top.
B6: Attach the smooth tubing tightly to the hole on the
unmarked side of the tube top.
B7: Insert the NO2 (red) needle into the center of the red
rubber septum on the NO2 assembly perpendicular to the plane of
the face of the septum as illustrated in Figure 42*
B8: Slide the base of the needle tightly onto the nipple of
the vacuum manifold as shown in Figure 42.
B9: Repeat steps B3 through B8 for the SO2 (blue) needle
and sample tube*
BIO; Turn the pump ON.
Bll: Record the vacuum gage reading under "START OPEN"
meter reading*
B12: Clamp the hose and record the vacuum gage reading
under "Start Meter Reading Clamp".
BL3: Turn the pump OFF.
B14: Set the timer to the correct time and date by turning
the timer disc in the direction indicated by the arrow until the
correct time is under the red line*
-------
B15: Set the sample run date and time trippers on the tiner
disc* The ON timer tripper is light colored and should be set
for midnight before the sample date and the OFF (dark) tripper
should be set for midnight at the end of the proposed sample
date*
