Red Hill

Risk and Vulnerability Assessment at Red Hill

The Administrative Order on Consent (AOC) requires the Navy and Defense Logistics Agency (DLA) to conduct an assessment of the risk posed by the facility to the groundwater resources. This risk assessment goes beyond a typical environmental risk assessment, which usually only analyzes the level of health risk posed by concentrations of contaminants in the environment. The risk assessment required by the AOC will evaluate the probabilities of various events that may result in the release of fuel into the surrounding environment. These events could include human error, mechanical failures, fires, or earthquakes. The assessment will study these types of scenarios and others to determine the likelihood of releases and their consequences. This risk assessment will provide important information to support contaminant modeling and tank upgrade decisions.

On April 13, 2017, the Navy and DLA submitted a scope of work for the risk and vulnerability assessment to the Hawaii Department of Health and EPA (the Regulatory Agencies) for approval. The Regulatory Agencies conditionally approved this scope of work on May 16, 2017. The Navy and DLA are required to submit a report containing a risk and vulnerability assessment for the facility to the Hawaii Department of Health and EPA by November 16, 2018.

The Regulatory Agencies’ conditional approval of the risk assessment scope of work required the Navy and DLA to provide the Regulatory Agencies with a report that compares the risks and benefits between the current fuel storage facility location and alternative fuel storage facility locations. On March 8, 2018 the Navy and DLA submitted the Red Hill Alternative Location Study, dated February 5, 2018.  A redacted version of this document is available for viewing below. Due to Federal contracting regulations and national security concerns, some information, such as the cost of constructing the new facility and specific information on the facilities’ capacities, cannot be publicly released.
