** DO NOT REJECT A TEST WITHOUT CONSULTING WITH THE STATIONARY SOURCE COMPLIANCE BRANCH. IF YOU HAVE
TESTING CONCERNS, DISCUSS THEM IMMEDIATELY WITH THE TESTING COMPANY AND SSCB. **

RECORD PROCESS DATA: It is imperative for the facility and the observer to record the pertinent data during the
test so that the measured emissions can be correlated to a production rate and compared to the permit limit. The test
will be unacceptable without production data. Control device operating parameters should also be recorded.
DATA TABLE: DGM stands for "dry gas meter", the volume of dry gas collected typically in cf. The "Vm" is the DGM
meter change from the beginning to the end of the run, which is the total dry gas volume collected. "Ave. ∆p" is the average
pitot tube velocity head for the points sampled (in inches H
O). "Nozzle ø" is the nozzle diameter, typically in inches. "H
O
2

Coll." is the water collected by Method 4. "Post leak" is the post leak check amount in cfm (see below).
METHOD 1: If stack is between 4" - 12" then Method 1a must be employed. If duct is <4" then alternative methods must be
used.
Stack Diameter:
How Determined?
Port Dist. upstream from disturbance (A):
Upstream Diameters (A):
Port Dist. downstream from disturbance (B):
Downstream Diameters (B):
Draw a line vertically from the "Distance A" axis down
to the step chart, and from the "Distance B" axis up to
the step chart. The maximum # of points marked on the
chart yields the minimum # of points to be sampled.
Minimum number of sampling points:
Points correctly marked on the pitot tube?
Port length accounted for in calculations?

2.5 Barometric Pressure: pressure must be adjusted minus 0.1" Hg per 100ft elevation increase or vice versa for elevation decrease.
2.8 Sample Volume (Vm): SIP Sources require 1hr particulate test runs and a minimum sample of 30 dscf. NSPS regulations may require
different sample rates, times, and temperatures. Investigate prior to test. Check "Vm" discussed above.
METHOD 3: The measurement of O
& CO
is usually performed with an analyzer. Orsats may be used but must meet analysis criteria (see
2
2
guidance document). Assuming ambient air and a molecular weight may be acceptable for some stacks (asphalt plants).
Calculate:
METHOD 4: See Method 26A (page 2) for impinger setup. Impinger Exit Temperature - The temperature of the dry gas leaving the
impingers/condenser must be below 68 Deg F. When the ambient temperature is above 68 Deg F it may take approximately 5 minutes for the
thermal effects of the ice bath to cool the exit thermometer below 68 Deg F.
METHOD 5:
Leak Check: If the results indicate a leak (>0.02cfm), record the leakage rate. Suggest repeating the run, but it is the discretion of the test
team and facility to accept the leak. However, the sample volume will be adversely adjusted due to the leakage rate.
Isokinetics: If the test team indicates that the isokinetic rate of a run is over 110% or under 90%, the run should be voided and repeated.
Particulate Sample Clean-up: If any particulate sample is lost during clean-up, the run should be voided and repeated.
REMARKS: (Record process data and applicable regulations here and/or in your observation report )
