The LWG provided the National Remedy Review Board and Contaminated Sediments Technical Advisory Group (NRRB and CSTAG) with comments and concerns on the FS and direction o f the cleanup for Portland Harbor. The Region is also considering those comments in revising the FS. To keep the remedy selection process moving forward and publish a Proposed Plan by March 2016, the EPA decided to complete the Feasibility Study rather than direct the LWG to incorporate our changes and produce the report. EPA can complete the work otherwise required o f the LWG under the Administrative disapproved as Settlement Agreement and Order on deficient. See Section IX, Paragraph C1oannsdenStec(AtioOnCX) IbXe,caPuasreagtrhaep2h091.2FdurratfhteFrmS owrae,s EPA can more effectively and efficiently incorporate changes to the FS to address stakeholder comments, the NRRB and CSTAG recommendations, and any issues raised during government to government consultations with Tribal governments. Given the EPA's decision, we expect the LWG has questions about the status o f its remaining work under the AOC, and dispute resolution rights. Work remains to be done under the AOC. The LWG must finalize the Remedial Investigation Report (RI). Sierra Club v.
