The Administrative Order on Consent (AOC) requires the Navy to develop a plan addressing the January 2014 fuel release from Tank #5 as well as plans to address any future releases of fuel. The Navy will evaluate various investigative techniques to determine which are most suitable for determining the extent of contamination in the ground around Red Hill. Each technique will be evaluated in terms of feasibility of implementation and effectiveness in detecting light non-aqueous phase liquid (LNAPL), which refers to fuel floating on top of the groundwater. The Navy will also investigate a number of remediation methods for use in the Red Hill area. The Navy will evaluate methods based on their feasibility of implementation, suitableness for use in fractured basalt geology, and effectiveness in reducing contamination.
In May 2016 the Navy submitted a scope of work to address the investigation and remediation of contamination, modeling and the groundwater monitoring network. On September 15, 2016 the Regulatory Agencies disapproved this scope of work and requested that the Navy revise the documet (review and disapproval letter is available in the Additional Documents page, see link above). The Navy submitted a revised scope of work on November 5, 2016 which was conditionally approved by the Regulatory Agencies on December 2, 2016 subject to changes as detailed in the conditional approval letter (letter is available for viewing below). On January 5, 2017, the Navy submitted a new version of the Section & 7 Scope of Work, available below, that addressed all of the issues noted in the Conditional Approval letter.
