11 Site I
11.1 Introduction
Sampling was carried out at Site I on 21 March 2003. Samples were collected from the Pillar and Whiting stacks to determine the concentration and mass emission of PCDD and PCDF present in the gases discharged to the atmosphere.
The sample port was at least five diameters from a flow disturbance after the fan.
Details of the sampling date, times and stack dimensions are:
- Sample date and time:
- Sample 1: 21 March 2003, Pillar Stack: 11:32-14:33
- Sample 2: 21 March 2003, Whiting Stack: 11:49-14:25
- Stack dimensions:
- Whiting - 700 mm diameter circular duct.
- Pillar - 400 mm x 400 mm metre rectangular duct.
