Run 3 Coal Samples from Units 1 (BW21) and 2 (BW22) were cross-labelled at time of collection. 

All Run 3-fuel-l sheets should be labelled 3-fuel-2. All Run 3-fuel-2 sheets should be labelled 3­

fuel-l. Sample cross-labelling was suspected due to ash content of each sample. Cross-labelling 

confirmed by analysis of correctly labelled sister samples retained by plant for daily analysis.
