17.20.090   Stack sampling.
   A.   Each mass-emissions discharge test for determining compliance with a standard shall consist of at least three runs (or an alternate number specified by the control officer) using the applicable test method as specified by EPA.
   B.   The arithmetic mean of the results of the three runs shall apply.
   C.   If a sample is accidentally lost or if one of the three runs must be discontinued due to forced shutdown, failure of an irreplaceable portion of the sampling train, extreme meteorological conditions, or other circumstances beyond the control of the source operator, the control officer may approve the use of the remaining test runs.
