dihydrogen phosphate in water and dilute to 100 ml.
(2.) To prepare the 1 M sodium hydroxide solution
(NaOH), dissolve 4.0 g of sodium hydroxide in water and
dilute to 100 ml.
( .) To prepare the buffered 2 percent potassium iodide
solution, dissolve 20 g of potassium iodide in 900 ml water.
Add 50 ml of the 1 M potassium dihydrogen phosphate solution
and 30 ml of the 1 M sodium hydroxide solution. While
stirring solution, measure the pH of solution
electrometrically and add the 1 M sodium hydroxide solution
to bring pH to between 6.95 and 7.05.
(i.) To prepare the 0.1 normality (N) sodium
thiosulfate solution, dissolve 25 g of sodium thiosulfate,
pentahydrate, in 800 ml of freshly boiled and cooled
distilled water in a 1-liter volumetric flask. Dilute to
volume. To prepare the 0.01 N sodium thiosulfate solution,
-------
62 9/25/97 P&P MACT I & III Rule
add 10.0 ml standardized 0.1 N sodium thiosulfate solution
to a 100 ml volumetric flask, and dilute to volume with
water.
( .) To standardize the 0.1 N sodium thiosulfate
solution, dissolve 3.249 g of anhydrous potassium bi-iodate,
primary standard quality, or 3.567 g potassium iodate dried
at 103 +1- 2 degrees Centigrade for 1 hour, in distilled
water and dilute to 1000 ml to yield a 0.1000 N solution.
Store in a glass-stoppered bottle. To 80 ml distilled
water, add, with constant stirring, 1 ml concentrated
sulfuric acid, 10.00 ml 0.1000 N anhydrous potassium bi-
iodate, and 1 g potassium iodide. Titrate immediately with
0.1 n sodium thiosulfate titrant until the yellow color of
the liberated iodine is almost discharged. Add 1 ml starch
indicator solution and continue titrating until the blue
color disappears. The normality of the sodium thiosulfate
solution is inversely proportional to the ml of sodium
thiosulf ate solution consumed:
Normality of 1
Sodium Thiosulfate ml Sodium Thiosulfate Consumed
-------
63 9/25/97 P&P MACT I & III Rule
( .) To prepare the starch indicator solution, add a
small amount of cold water to 5 g starch and grind in a
mortar to obtain a thin paste. Pour paste into 1 L of
boiling distilled water, stir, and let settle overnight.
Use clear supernate for starch indicator solution.
(1) To prepare the 10 percent sulfuric acid solution,
add 10 ml of concentrated sulfuric acid to 80 ml water in an
100 ml volumetric flask. Dilute to volume.
(F) The procedures specified in paragraphs
(b) (5) (ii) (F) (. ) through (b) (5) (ii) (F) ( .) of this section
shall be used to perform the sampling.
( ) Preparation of Collection Train. Measure 20 ml
buffered potassium iodide solution into each of the first
two impingers and connect probe, impingers, filter, critical
orifice, and pump. The sampling line and the impingers
shall be shielded from sunlight.
(2.) Leak and Flow Check Procedure. Plug sampling line
inlet tip and turn on pump. If a flow of bubbles is visible
in either of the liquid impingers, tighten fittings and
adjust connections and impingers. A leakage rate not in
excess of 2 percent of the sampling rate is acceptable.
-------
64 9/25/97 P&P MACT I & III Rule
Carefully remove the plug from the end of the probe. Check
the flow rate at the probe inlet with a bubble tube flow
meter. The flow should be comparable or slightly less than
the flow rate of the critical orifice with the impingers
off-line. Record the flow and turn off the pump.
(. .) Sample Collection. Insert the sampling line into
the stack and secure it with the tip slightly lower than the
port height. Start the pump, recording the time. End the
sampling after 60 minutes, or after yellow color is
observed in the second in-line impinger. Record time and
remove the tubing from the vent. Recheck flow rate at
sampling line inlet and turn off pump. If the flow rate has
changed significantly, redo sampling with fresh capture
solution. A slight variation (less than 5 percent) in flow
may be averaged. With the inlet end of the line elevated
above the impingers, add about 5 ml water into the inlet tip
to rinse the line into the first impinger.
( ) Sample Analysis. Fill the burette with 0.01 N
sodium thiosulfate solution to the zero mark. Combine the
contents of the impingers in the beaker or flask. Stir the
solution and titrate with thiosulfate until the solution is
-------
65 9/25/97 P&P X? CT X & X XX Rule
colorless. Record the volume of the first endpoint (TN,
ml). Add 5 ml of the 10 percent sulfuric acid solution, and
continue the titration until the contents of the flask are
again colorless. Record the total volume of titrant
required to go through the first and to the second endpoint
(TA, ml) . If the volume of neutral titer is less than
0.5 ml, repeat the testing for a longer period of time. It
is important that sufficient lighting be present to clearly
see the endpoints, which are determined when the solution
turns from pale yellow to colorless. A lighted stirring
plate and a white background are useful for this purpose.
(5.) Interferences. Known interfering agents of this
method are sulfur dioxide and hydrogen peroxide. Sulfur
dioxide, which is used to reduce oxidant residuals in some
bleaching systems, reduces formed iodine to iodide in the
capture solution. It is therefore a negative interference
for chlorine, and in some cases could result in erroneous
negative chlorine concentrations. Any agent capable of
reducing iodine to iodide could interfere in this manner. A
chromium trioxide impregnated filter will capture sulfur
dioxide and pass chlorine and chlorine dioxide. Hydrogen
-------
66 9/25/97 P&P MACT I & III Rule
peroxide, which is commonly used as a bleaching agent in
modern bleaching systems, reacts with iodide to form iodine
and thus can cause a positive interference in the chlorine
measurement. Due to the chemistry involved, the precision
of the chlorine analysis will decrease as the ratio of
chlorine dioxide to chlorine increases. Slightly negative
calculated concentrations of chlorine may occur when
sampling a vent gas with high concentrations of chlorine
dioxide and very low concentrations of chlorine.

8.1.2 Leak Check. A leak check prior to the sampling
run is optional; however, a leak check after the sampling
run is mandatory. The leak-check procedure is as follows:
Temporarily attach a suitable (e.g., 0- to 40-mi/mm)
rotameter to the outlet of the DGM, and place a vacuum gauge
at or near the probe inlet. Plug the probe inlet, pull a
vacuum of at least 250 mm (10 inch) Hg, and note the flow
rate as indicated by the rotameter. A leakage rate not in
excess of 2 percent of the average sampling rate is
acceptable. NOTE: Carefully release the probe inlet plug
before turning off the pump.
8.1.3 Sample Collection. Record the initial DGM
reading and barometric pressure. To begin sampling,
position the tip of the Teflon® tubing at the sampling
point, connect the tubing to the impinger, and start the
pump. Adjust the sample flow to a constant rate between
200 and 1000 mi/mm as indicated by the rotameter. Maintain
this constant rate (±10 percent) during the entire sampling
run. Take readings (DGM, temperatures at DGM and at
impinger outlet, and rate meter) at least every 5 minutes.
Add more ice during the run to keep the temperature of the
-------
104 9/25/97 P&P MACT I & III Rule
gases leaving the last impinger at 20 0 C (68 °F) or less.
At the conclusion of each run, turn off the pump, remove the
Teflon® tubing from the stack, and record the final
readings. Conduct a leak check as in section 8.1.2. (This
leak check is mandatory.) If a leak is found, void the test
run or use procedures acceptable to the Administrator to
adjust the sample volume for the leakage.
8.2 Sample Recovery. The following items are required
for sample recovery:
8.2.1 Impinger. Disconnect the impinger. Pour the
contents of the midget impinger into a graduated cylinder.
Rinse the midget impinger and the connecting tubes with
water, and add the rinses to the graduated cylinder. Record
the sample volume. Transfer the sample to a glass vial and
cap with a Teflon® septum. Discard any excess sample.
Place the samples in an ice chest for shipment to the
laboratory.
8.2.2. Adsorbent Tubes. Seal the silica gel adsorbent
tubes and place them in an ice chest for shipment to the
laboratory.

9.2 Applicability. When the method is used to analyze
samples to demonstrate compliance with a source emission
regulation, an audit sample must be analyzed, subject to
availability.
9.3 Audit Procedure. Analyze an audit sample with
each set of compliance samples. Concurrently analyze the
audit sample and a set of compliance samples in the same
manner to evaluate the technique of the analyst and the
standards preparation. The same analyst, analytical
reagents, and analytical system shall be used both for the
compliance samples and the EPA audit sample.
9.4 Audit Sample Availability. Audit samples will be
supplied only to enforcement agencies for compliance tests.
Audit samples may be obtained by writing:
-------
106 9/25/97 P&P MP CT I & III Rule
Source Test Audit Coordinator (MD-77B)
Air Measurement Research Division
National Exposure Research Laboratory
U.S. Environmental Protection Agency
Research Triangle Park, NC 27711
or by calling the Source Test Audit Coordinator (STAC) at
(919) 541-7834. The audit sample request must be made at
least 30 days prior to the scheduled compliance sample
analysis.
9.5 Audit Results. Calculate the audit sample
concentration according to the calculation procedure
provided in the audit instructions included with the audit
sample. Fill in the audit sample concentration and the
analyst’s name on the audit response form included with the
audit instructions. Send one copy to the EPA Regional
Office or the appropriate enforcement agency and a second
copy to the STAC. The EPA Regional office or the
appropriate enforcement agency will report the results of
the audit to the laboratory being audited. Include this
response with the results of the compliance samples in
relevant reports to the EPA Regional Office or the
appropriate enforcement agency.
10.0 Calibration and Standardization.
-------
107 9/25/97 P&P MACT I & III Rule
10.1 Metering System. The following items are
required for the metering system:
10.1.1 Initial Calibration.
10.1.1.1 Before its initial use in the field, first
leak-check the metering system (drying tube, needle valve,
pump, rotameter, and DGM) as follows: Place a vacuum gauge
at the inlet to the drying tube, and pull a vacuum of 250 mm
(10 inch) Hg; plug or pinch off the outlet of the flow
meter, and then turn off the pump. The vacuum shall remain
stable for at least 30 seconds. Carefully release the
vacuum gauge before releasing the flow meter end.
10.1.1.2 Next, remove the drying tube, and calibrate
the metering system (at the sampling flow rate specified by
the method) as follows: Connect an appropriately sized wet
test meter (e.g., 1 liter per revolution (0.035 cubic feet
per revolution)) to the inlet of the drying tube. Make
three independent calibrations runs, using at least five
revolutions of the DGM per run. Calculate the calibration
factor, Y (wet test meter calibration volume divided by the
DGM volume, both volumes adjusted to the same reference
temperature and pressure), for each run, and average the
-------
108 9/25/97 P&P M CT I & III Rule
results. If any Y-value deviates by more than 2 percent
from the average, the metering system is unacceptable for
use. Otherwise, use the average as the calibration factor
for subsequent test runs.
10.1.2 Posttest Calibration Check. After each field
test series, conduct a calibration check as in
section 10.1.1 above, except for the following variations:
(a) the leak check is not to be conducted, (b) three, or
more revolutions of the DGM may be used, and Cc) only two
independent runs need be made. If the calibration factor
does not deviate by more than 5 percent from the initial
calibration factor (determined in section 10.1.1), then the
DGM volumes obtained during the test series are acceptable.
If the calibration factor deviates by more than 5 percent,
recalibrate the metering system as in section 10.1.1, and
for the calculations, use the calibration factor (initial or
recalibration) that yields the lower gas volume for each
test run.
10.1.3 Temperature Sensors. Calibrate against
mercury-in-glass thermometers.
-------
109 9/25/97 P&P XA CT I & III Rule
10.1.4 Rotameter. The rotameter need not be
calibrated, but should be cleaned and maintained according
to the manufacturer’s instruction.
10.1.5 Barometer. Calibrate against a mercury
barometer.
10.2 Gas Chromatograph. The following procedures are
required for the gas chromatograph:
10.2.1 Initial Calibration. Inject 1 l of each of
the standards prepared in sections 7.2.3.3 and 7.2.3.4 into
the GC and record the response. Repeat the injections for
each standard until two successive injections agree within
5 percent. Using the mean response for each calibration
standard, prepare a linear least squares equation relating
the response to the mass of methanol in the sample. Perform
the calibration before analyzing each set of samples.
10.2.2 Continuing Calibration. At the beginning of
each day, analyze the mid level calibration standard as
described in section 10.5.1. The response from the daily
analysis must agree with the response from the initial
calibration within 10 percent. If it does not, the initial
calibration must be repeated.
-------
110 9/25/97 P&P MACT I & III Rule
11.0 Analytical Procedure .
11.1 Gas Chromatograph Operating Conditions. The
following operating conditions are required for the GC:
11.1.1 Injector. Conf-igured for capillary column,
splitless, 200 0 C (392 °F)
11.1.2 Carrier. Helium at 10 mi/mm.
11.1.3 Oven. Initially at 45 0 C for 3 minutes; then
raise by 10 °C to 70 0 C; then raise by 70 °C/min to 200 °C.
11.2 Impinger Sample. Inject 1 /21 of the stored
sample into the GC. Repeat the injection and average the
results. If the sample response is above that of the
highest calibration standard, either dilute the sample until
it is in the measurement range of the calibration line or
prepare additional calibration standards. If the sample
response is below that of the lowest calibration standard,
prepare additional calibration standards. If additional
calibration standards are prepared, there shall be at least
two that bracket the response of the sample. These
standards should produce approximately 50 percent and 150
percent of the response of the sample.
-------
111 9/25/97 P&P MACT I & I II Rule
11.3 Silica Gel Adsorbent Sample. The following items
are required for the silica gel adsorbent samples:
11.3.1 Preparation of Samples. Extract the front and
backup sections of the adsorbent tube separately. With a
file, score the glass adsorbent tube in front of the first
section of silica gel. Break the tube open. Remove and
discard the glass wool. Transfer the first section of the
silica gel to a 5-mi glass vial and stopper the vial.
Remove the spacer between the first and second section of
the adsorbent tube and discard it. Transfer the second
section of silica gel to a separate 5-mi glass vial and
stopper the vial.
11.3.2 Desorption of Samples. Add 3 ml of the
10 percent n-propanol solution to each of the stoppered
vials and shake or vibrate the vials for 30 minutes.
11.3.3 Inject a 1-/. l aliquot of the diluted sample
from each vial into the GC. Repeat the injection and
average the results. If the sample response is above that
of the highest calibration standard, either dilute the
sample until it is in the measurement range of the
calibration line or prepare additional calibration

standards. If the sample response is below that of the
lowest calibration standard, prepare additional calibration
standards. If additional calibration standards are
prepared, there shall be at least two that bracket the
response of the sample. These standards should produce
approximately 50 percent and 150 percent of the response of
the sample.
