SECTION 1.0
INTRODUCTION
Revisions to the State Implementation Plan (SIP) for ozone are required
in 1982. The State of Ohio must obtain Non-methane Organic Compound (NMOC)
data for days of high ozone concentrations during the summer of 1981. Data
were especially needed in the vicinity of Cleveland and Cincinnati to pro-
vide the needed input into the predictive model that will be used to demon-
strate attainment of the ambient ozone standard.
To obtain this data two NMOC analyzers were operated in both Cleveland
and Cincinnati by the local agency. PEDCo Environmental, Inc. was con-
tracted to assist the local agencies in the installation, start up, main-
tenance and quality assurance of the four analyzers.
The sites located in Cleveland were the Rickoff School site at 147th
Street, and the St. Vincent's site located at Woodland and 22nd Streets.
The Cincinnati sites were the University CAM site located at Vine and St.
Clair Streets, and the Norwood site located at 300 Harris Avenue.
Instruction was given to the local operators on the routine operation
and maintenance of the NMOC analyzers, according to the procedures published
in the EMSL report EPA-600/4-81-015, March 1981. Standard Operating
Procedures (SOP) (Appendix A), were supplied to the local operators.
The following sections describe the calibration procedure and quality
assurance activities.

SECTION 2.0
CALIBRATION PROCEDURES
2.1 INTRODUCTION
The NMOC analyzers were scheduled to be calibrated approximately every
two weeks, however, this schedule was not always met. This was primarily
due to instrument malfunctions, and scheduling difficulties.
Every effort was made to calibrate each site within the prescribed time
frame. However, priority was given to those instruments which were subject
to downtime or drifting out of calibration. Those instruments which did not
exhibit excessive drift were given a lower priority and were calibrated
after the problem instruments had been serviced and calibrated.
2.2 NMOC CALIBRATION
2.2.1 Calibration Equipment
The NMOC analyzers were calibrated using EPA certified methane and
propane calibration gases. The gases were certified prior to start of the
project. Table 1 lists the tanks and certified concentrations.

These gases were then diluted with compressed air (<0.01 ppm HC) using a
porous plug dilution system. The system used throughout the project was
Serial No. RTI-PE-103. Flows were measured with a Hastings NBS traceable
bubblemeter.
2.2.2 Calibration Procedure
The following is the stepwise procedure used to calibrate the MSA 11-2
continuous analyzer. The analyzer should be allowed to warm up for approxi-
mately 24 hours prior to calibration.
NOTE: The analyzer was calibrated and operated with the elec-
trometer in the subtraction mode.
All calibration data was recorded on a calibration data form (Figure 1).
The calibration data has been sent to the Project Officer.
1. If this is an initial calibration, shut off the vent flow for
checking; it should be checked and adjusted prior to the calibra-
tion.
2. Check the moisture drop-out traps located on the back of the
analyzer for the accumulation of water. Drain any water accumu-
lation in the second water trap toward the instrument. In the
first water trap after the sample pump, maintain % inch to 2
inches of water. Any water accumulation higher than % inch should
be drained to that level.
3. Quickly check the back-pressure regulator vent flow located inside
the oven. Vent flow from each regulator should be 400 to 600
cc/min. These flows should be closely matched.
4. Check analyzer sample inlet pressures. The air pressure gauge on
the front of the instrument should be 20 ± 1 psig. The pressure
gauge between the water traps and the instrument on the back of
the analyzer should be 30 ± 2 psig. The pressure gauge between
the two water traps should be greater than 40 psig. If the pump
will not maintain at least 40 psig, check for leaks in the water
trap system or water and dirt in the sample pump.
5. Check that the range selector switch is in the 0 to 10 ppm range.
6. Disconnect the analyzer's sample line from the ambient manifold
and reconnect it to the calibration system's manifold. Cap the f
port on the ambient manifold and any open ports on the calibration I
system's sample manifold.

7. Supply an atmosphere of the zero standard to the manifold at a te
flow rate that is 20 to 50% greater than the analyzer's sample
flow demand. DO NOT PRESSURIZE THE ANALYZER'S SAMPLE INLET. The
test atmosphere must contain an ambient level of oxygen and must
not contain more than 0.1 ppmC TOC.
8. Adjust the analyzer's zero controls for both channels to the
desired baseline responses. A 5% of full scale positive offset on
the recording device is recommended to observe any negative drift.
Use either the analyzer's zero pots or the recorder's controls to
obtain the offset. Ensure that the responses from both channels
are .equal before recording the responses on the calibration data
sheet.
9. Supply an atmosphere of methane standard to the calibration mani-
fold at a flow rate that is 20 to 50% greater than the analyzer's
sample flow demand. The methane concentration should be between
70 and 90% full scale.
10. Adjust span pot #2 (which controls CH4 response from FID #2) to
provide the analyzer response calculated as follows:
D ~ - Sample concentration u , ^ , ., .
Response = c rj^- X url + Zero offset
where
Response = Response of the recording device measuring the
analyzer output in recording device units.
Sample concentration = Concentration of the calibration standard
delivered to the analyzer in ppmC.
URL = The upper range limit of the analyzer in ppmC.
url = The upper range limit of the recording device in recording
device units.
Zero offset = The amount the recording device response is set
above the zero baseline while the analyzer is
measuring the zero calibration standard (in
recording device units).
11. If step 10 results in a span pot setting greater than 300,
decrease pressure to H2 gauge #2 until the CH4 response has
increased to a point where the span pot can be reduced to about
250. If the span pot setting is less than 200, increase pressure
to H2 gauge #2 until the CH4 response has decreased to a point
where the span pot can be increased to about 250. DO NOT EXCEED
9.0 psig H2.
NOTE: IF THE FID 'RESPONSE INCREASES WHEN INCREASING
HYDROGEN PRESSURE, THE BURNER IS OPERATING ON THE WRONG
2-5
-------
SIDE OF ITS PEAK RESPONSE CURVE. CONTINUE INCREASING
HYDROGEN PRESSURE UNTIL RESPONSE STARTS TO DECREASE AND
THE CORRECT SPAN POT SETTING IS OBTAINED.
12. Set span pot #1 NMOC to the same dial setting (not response) as
span pot #2.
13. Repeat steps 7, 8, 9, 10, 11, and 12 if span pot adjustments were
necessary or if hydrogen pressure gauge #2 was adjusted.
14. Continue sampling the methane standard. For the FIDs to be
balanced, the NMOC response must be within ±1.0% of the zero
response obtained in step 8. If the FIDs are balanced, go to step
16.
15. Balance detectors: If the FIDs are not balanced:
(a) Check that both span pots are dialed to the same setting.
(b) Locate the range change board (inside the electrometer
assembly located in the oven) and rotate the balance controls
of channels 1 and 2 (accessible through holes in the elec-
trometer cover) to their maximum clockwise position. Make
adjustments quickly to minimize heat loss!
(c) Record both hydrogen pressure gauge readings. Adjust
hydrogen pressure gauge #1 until the NMOC response to the
methane standard equals the earlier NMOC response to the zero
standard (step 8).
Do not adjust the hydrogen pressure outside the 5 to 9 psig
range. Increase hydrogen pressure to decrease NMOC response,
or vice versa. See the note in step 11.
(d) If balance is achieved, repeat steps 7 through 15.
(e) If balance is not achieved by step c, adjust the NMOC
hydrogen pressure (gauge #1) or both hydrogen pressure, if
necessary, to get as close to balance (NMOC response within ±
1% of NMOC zero response) as possible. Do not exceed the 5
to 9 psig hydrogen pressure range. Then, using the balance
controls on the range change board located inside the elec-
trometer (accessible through holes in the electrometer
cover), rotate the channel #2 balance control counter-
clockwise to increase the NMOC response, or rotate the
channel #1 balance control counter-clockwise to decrease the
NMOC response. Repeat steps 7 through 14.
16. After the FIDs are balanced, record responses on the Calibration
Data Sheet. Determine the CH4 channel's response to three addi-
tional concentrations of the methane standard that are spaced
approximately equally over the analyzer range. (The NMOC
2-6

channel's response should remain equal to the earlier response to
zero standard.) Record the CH4 and NMOC channel's responses (from
the recording device) on the data sheet. Using a calculator,
perform a least squares linear regression corresponding calibra-
tion concentrations. The calibration concentrations should be in
units of ppmC and should be entered into the calculator as the
independent variable X. The CH4 channel's response should be in
units of the recording device and should be entered as the
dependent variable Y. A correlation coefficient (r) of 0.9996 or
better verifies that the CH4 response is linear. (If the response
is not linear, plot the data and determine if an error has been
made in data entry or in determination of calibration concentra-
tion.) Obtain the slope and intercept of the regression and
record the equation in the following form:
CH4 Response = CH4 Slope x Methane concentration + CH4 Intercept
where
CH4 Response = Analyzer's CH4 channel reading in recording device
units (see note following step 10).
CH4 Slope = Regression slope in recording device units per ppmC.
Methane concentration = Calibrated methane concentration in ppmC.
CH4 Intercept = Regression intercept in recording device units.
Post the CH4 channel's multipoint calibration curve equation on the
analyzer's recording device and also on the Calibration Data Sheet.
17. Supply an atmosphere of propane standard to the calibration mani-
fold at a flow rate that is 20 to 50% greater than the analyzer's
sample flow demand. The propane concentration should be between
70 and 90% of full scale.
18. Adjust span pot #1 (which controls NMOC response from FID #1) to
provide the desired analyzer response.
19. If an adjustment is made in step 18, recheck the NMOC channel's
response to the zero standard and adjust zero pot #1 if necessary.
Record the stable zero responses from the NMOC and CH4 channels.
Sample the propane standard, and again record the stable responses
to propane. (CH4 response should be equal to the earlier response
to zero air.)
20. Determine the NMOC channel's response to three additional concen-
trations of the propane standard that are spaced approximately
equally over the analyzer range. (The CH4 channel's response
should remain equal to the earlier response to zero standard.)
Record the NMOC and CH4 channel's responses (from the recording
device) on the Calibration Data Sheet. Using a calculator,
perform a least squares linear regression of the NMOC channel's

response (to propane and zero standards) and the corresponding |*
propane calibration concentrations. The calibration concentra- |
tions should be in units of ppmC and should be entered as the fe
dependent variable Y. A correlation coefficient (r) of 0.9996 or I
better verifies that the NMOC response is linear. (If the f
response is not linear, plot the data and determine if an error *
has been made in data entry or in determination of calibration
concentration.) Obtain the slope and intercept of the regression I"
and record the equation in the following form: f
NMOC Response = NMOC Slope x NMOC Concentration + NMOC Intercept t
where ;
NMOC Response = Analyzer's NMOC channel reading in recording
device units (see note following step 10).
NMOC Slope = Regression slope in recording device units per ppmC. I
NMOC Concentration = Calibrated NMOC concentration in ppmC. j-
NMOC Intercept = Regression intercept in recording device units. ;
Post the NMOC channel's multipoint calibration curve equation
on the analyzer's recording device and on the Calibration Data I
Sheet. u
21. Disconnect the analyzer's sample line from the calibration system's
manifold and reconnect it to the ambient manifold. I
22. Be certain that the station log book, strip charts, etc. are properly
dated and signed. *

SECTION 3
QUALITY ASSURANCE PROGRAM
3.1 INTRODUCTION
Throughout the project several quality assurance activities were per-
formed. These included a daily zero and span check, a two point precision
check that was performed twice a week, two systems audits that were
performed by the EPA contractor Research Triangle Institute (RTI) during the
project, and a data validation, performed on the data before it was reduced.
The following sections will detail the above mentioned QA activities.
3.2 ZERO AND SPAN CHECKS
Each day during the project the monitoring sites were visited by the
local operator to perform the daily checks. These checks were recorded on
the Daily Check Sheet.
The zero/span system utilized a needle flow controller and a system of
"quick connect" valves to connect the appropriate cylinder to the analyzer.
The zero and span values obtained were marked on the strip chart and
recorded in the operators log book and on the Daily Zero and Span Data Sheet
(Figure 2). Any time the zero or span values were ±10 percent of the cali-
bration zero (including 5% offset) or span values, the local operator con-
tacted the PEDCo project manager in Cincinnati and then the instrument was
recalibrated.
All zero and span data has been sent to the project officer in a
separate volume.

3.3 PRECISION CHECKS
A two point precision check for the NMOC analyzers was carried out at
each site twice a week. These checks were performed after 9 a.m. EST and on
Mondays and Thursdays. The precision check data was recorded on Precision
Check Data Forms (supplied by U.S. EPA). These data are tabulated in
Appendix B. The precision check data was used in addition to the zero and
spans as an indicator for when recalibration was necessary.
3.4. SYSTEMS AUDIT
The NMOC monitoring network was audited twice during the study period
by the EPA contractor Research Triangle Institute (RTI). Table 2 lists the
audit results for the sites. Only the St. Vincent site was found to have a
response greater than 15 percent of the audit value. The instrument was
recalibrated the following day.
3.5 DATA VALIDATION AND AUDIT
PEDCo's field operator removed, on a bi-weekly basis, the strip charts
from each of the four instruments. The data was then validated and turned
over to the local agency for reduction and entry into the State's data base.
Every effort was made to accomplish this task within a two-week period,
however, instrument malfunctions prevented the field operator from keeping
to the bi-weekly schedule.
Data was invalidated when the zero, span or precision point data were
found to have drifted by more than fifteen percent.

SECTION 4
SITE OPERATION SUMMARY
4.1 RICKOFF SCHOOL SITE
The NMOC analyzer at this site was initially calibrated and put on line
on June 11, 1981. The instrument operated throughout the study without any
problems with the exception of a one week period in late June. The flames
went out on June 17 and were not able to be relit until June 19. It was
determined that this problem was due to a pump malfunction which caused
fluctuating pressures.
On June 22 there was a power failure which caused the loss of approxi-
mately one day's worth of data. After these problems were corrected the
analyzer operated without incident.
4.2 ST. VINCENT'S SITE
The St. Vincent's site was initially calibrated on June 4, 1981. The
only problem experienced at this site was the failure of the temperature
control board for the oxidizer. A new control board was ordered on July 1,
1981 and installed on July 14, 1981. After this was corrected there were no
other problems at this site.
4.3 UNIVERSITY CAM SITE
The University CAM site was initially calibrated and put on line on
June 1, 1981. This site operated without any major problem for the entire
study period. The only minor problem was with the NMOC strip chart on June
2, 1981.
4-1
-------
4.4 NORWOOD SITE
The Norwood site was initially calibrated and put on line on June 8,
1981. The site operated without any major problems until August 4, 1981.
At this time the instrument drifted out of balance. Due to scheduling
conflicts the analyzer was not recalibrated until August 10, 1981.
On September 4, 1981 several hours of data were lost when the CH4
channel strip chart was allowed to run out.
The air conditioner at the site went out on September 25, 1981. The
analyzer was shut down until September 26 to prevent damage to the analyzer
due to overheating.
Other than these few problems, the analyzer operated throughout the
study period.

ZERO AND SPAN CHECK
STANDARD OPERATING PROCEDURE (SOP)
MSA-11-2 NMOC ANALYZER
After completing the daily checklist, begin the zero and span check
according to the following stepwise procedure.
1. Check moisture trap No. 1 on the side of the instrument. If it
contains more than 1" of water, open valve SLOWLY and drain to a
level of 1/4". Do not drain completely.
2. Check moisture trap No. 2, also on the side of the instrument. If
it contains more than 1/2" of water, open the toggle valve and
drain.
3. Check both pressure gauge (No. 1 and No. 2). No. 1 should read
approximately 40 psig. No. 2 should read 10 psig less than No. 1,
adjust No. 2 if it does not.
4. Disconnect the "pump inlet" line from the sample manifold to the
vacuum side of the pump. Then connect the "T-line" to the same
fitting. CAUTION: Do not over-tighten the connection, finger
tight and then a 1/4 turn with the wrench should suffice.
5. Connect the zero stem to the "quick connect" side of the "T-line".
Check for excess flow through the open end of the "T-line". Flow
through the "T-line" may be increased by turning the knob on the
face of the regulator clockwise. Decrease the flow by turning the
knob counter-clockwise.
6. Allow sufficient time (approximately 5 to 10 minutes) for the
analyzer to stabilize. Record the zero value on the daily check-
list, the daily zero/span data sheet and plot the value on the
zero/span chart. Note - the pressure on the span and zero tank
should be 60 lb/in.2
7. Disconnect the zero stem and connect the SPAN stem to the
"T-line". Check for excess flow through the open end of the
"T-line". Flow through the "T-line" may be increased by turning
the knob on the face of the regulator clockwise. Decrease the
flow by turning the knob counter-clockwise.
8. Allow sufficient time (approximately 5 to 10 minutes) for the
analyzer to stabilize. Record the span value on the daily check-
list, the daily zero/span data sheet and plot the value on the
zero/span chart.

9. If either value for both Channel 1 and Channel 2 are off by more
than the 10 percent indicated on the control chart, call the PEDCo
Project Manager, Ed Mull in (513) 782-4700 immediately.
10. Disconnect the SPAN stem from the "T-line". If a precision check
is to be performed at this time, continue with the SOP for preci-
sion checks, if not, then proceed to step 11.
11. Disconnect the "T-line" from the vacuum side of the pump. Connect
the pump inlet line to the pump fitting. CAUTION: Do not over-
tighten the connection, finger tight and a 1/4 turn with the
wrench should suffice.
12. Label both zero and span points on the strip charts, record the
time and date and sign both strip charts.

PRECISION CHECK
STANDARD OPERATING PROCEDURE
The following procedure for precision checks is to follow step 10 of
the ZERO and SPAN check SOP.
1. Connect the precision check gas cylinder No. 1 (Precis. Ck. No. 1)
stem to the quick connect side of the "T-line". Check for excess
flow through the open end of the "T-line". Flow through the
"T-line" may be increased by turning the knob on the face of the
regulator clockwise. Decrease the flow by turning the knob
counter-clockwise. Allow sufficient time (approximately 5 to 10
minutes) for the analyzer to stabilize. Record the precision
check point No. 1 valve on the form and label the strip charts.
Note - the pressure for the precision span tanks should be 60
lb/in.2
2. Disconnect the Precis. Ck. No. 1 stem and connect the Precis. Ck.
No. 2 stem to the "T-line". Check for excess flow through the
open end of the "T-line". Flow through the "T-line" may be
increased by turning the knob on the face of the regulator clock-
wise. Decrease the flow by turning the knob counter-clockwise.
Allow sufficient time (approximately 5 to 10 minutes) for the
analyzer to stabilize. Record the precision check point No. 2
valve on the form and label the strip charts.
3. Disconnect the Precis. Ck. No. 2 stem from the "T-line".
4. Disconnect the "T-line" from the vacuum side of the pump. Connect
the "pump inlet" line to the pump fitting. CAUTION: Do not
overtighten the connection, finger tighten and a 1/4 turn with the
wrench should suffice.
5. Label both precision points on the strip charts, record the time
and date, and sign both strip charts. NOTE: If a zero and span
check was also performed, label these points on the strip charts.

RELIGHTING BURNER
STANDARD OPERATING PROCEDURE
If the flame out indicator is ON (the light will be on), the burner(s)
will need to be relit. The following stepwise procedure should be completed
before calling the PEDCo Project Manager, Ed Mullin (513) 782-4700. If the
burner does not relight easily, call the PEDCo Project Manager.
1. Adjust the AIR regulator (on the face of the instrument) to 5 to
10 psig.
2. Press the IGNITION button (also the flame out indicator) for a
count of three. If the burner has been out a while, it will take
several attemps to successfully relight the burner.
3. If the burner does not ignite on the first try, repeat 3 or 4 more
times. NOTE: It will take several seconds for the light to go
out after the burner ignites.
4. Adjust the AIR regulator to 20 psig.
5. Record on all the strip charts which channel was relit and when.

ABSTRACT
This program was proposed to obtain Non-Methane Organic
Compound (NMOC) data for
djays of high ozone concentration during the summer of 1981. Data were especially
nleeded in the vicinity of Cleveland and Cincinnati to provide the needed input
into the productive model that will be used to demonstrate attainment
of the
ambient ozone standard.
