Pulp and paper technical guidance: questions and answers to assist mills, chapter 11

What if a mill has unconfirmed effects?

Mills with unconfirmed effects (i.e., results of consecutive cycles are inconclusive or inconsistent) can examine data and information from all EEM studies conducted to date and, using a weight-of-evidence approach, determine if the data are interpretable. Data and information from other studies conducted at the same location can be used to help interpret EEM results. If data are interpretable and indicate that effects are present, the mill can conduct investigations with the level of effort appropriate to the magnitude and type of effects observed. If data are not interpretable, the mill considers whether improvements can be made to the study design and continues to monitor the components to assess effects.
