The aim of this short guidance is to set out the Agency’s required approach to the application of 95% Confidence intervals under LCPD and WID. This guidance applies to WID and LCPD licensed facilities only. The WID and LCPD express uncertainty budgets and 95% confidence intervals at the ELV. The uncertainty budget can be viewed as an allowable margin of error in the measurement, as a combination of the systematic and random errors. Validated hourly and daily average values are determined from the measured valid hourly average values after taking the calculated confidence interval into account.
