Page 1133 Section Q - Method 1 states "The test for the presence or absence of cyclonic flow would be required for all tests instead of recommended at sites suspected of having cyclonic flow." Are cyclonic flow checks now required on rectangular stacks? Page 11 Section FF. - Method 7E states "A statement noting that the stratification test is not required at sources with temporally varying emissions" Could you provide clarification? If the source's emissions are temporarily varying why not wait and test when the emissions are stable?
