A supplemental hazard analysis was conducted and quantitative risk assessment performed in response to an independent review comment received by the Pacific Northwest National Laboratory (PNNL) from the U.S. Department of Energy Pacific Northwest Field Office (PNSO) against the Hydrotreater/Distillation Column Hazard Analysis Report issued in April 2013. The comment states: “…based on our independent review and in light of our code responsibilities as the owner, we are directing Battelle to provide PNSO with the following items prior to start-up of the distillation column: … “3. Identification of prudent protective actions for the worker and the public (e.g., setback distances, shielding, procedures for minimizing time in the higher risk areas during operation, etc.) based on quantitative analysis and practical risk minimization approaches (for the distillation column). Items 1 and 3 are also expected to be provided to PNSO for the hydrotreater unit prior to its operation…” (Emphasis added)
