Sampling was carried out at Site K on 2 and 3 April 2003. Samples were collected from the induction furnace discharge to determine the concentration and mass emission of PCDD and PCDF present in the gases discharged to the atmosphere.
The sampling point was in a vertical section of duct after the baghouse at least three diameters from any disturbance to the flow.
Details of the sampling date, times and stack dimensions are:
