Creating impact With uncertainty requirements facilitating extension of the SRM to industries regulated via BAT Conclusions documents, national regulators will be able to carry out enforcement interventions as they will have the necessary justification that an emissions breach has occurred ‘beyond reasonable doubt’. They will also be able to fully comply with the requirements of the European Pollutant Release and Transfer Register (E-PRTR [10]) which stipulate that reported data shall be “…satisfactory with respect to its completeness, consistency and accuracy” [11]. Additionally, this will provide a monitoring and enforcement framework in which both process plant operators and stack testing organisations alike can have confidence. This will ensure the latter are implementing measurement methods that meet regulatory requirements and that the former are protected from the risk of false negatives/positives and all the reputational damage and consequential business costs that could unfairly follow.
