Excerpt: "This letter and the enclosed reports and memoranda are based upon either an event (Hurricane Harvey) that occurred after the close of the public comment period on the PRAP or on a document, the October 2, 2017 USEPA Region 6 Memorandum, that was submitted to the Remedy Review Board following the close of the common period."
Excerpt: "Hurricane Harvey was certainly an “ultra-extreme” event, and should be considered a defining ultra-extreme event…The Time Critical Removal Action (TCRA) cap withstood the forces of Harvey, with only small areas of the TCRA armor being affected. "
Excerpt: "Hurricane Harvey was an extreme event and its occurrence creates an unusual opportunity to test assertions regarding long-term stability of the TCRA Armored Cap in the face of extreme hydrologic events and stresses. "
Excerpt: "Results of the evaluation confirm that Harvey was an extreme flood event with high velocities acting over the Armored Cap. Based on the modeling performed, it does not appear that Harvey produced higher forces on the Armored Cap than the large range of storm conditions simulated as part of both the TCRA (Anchor QEA 2010) and Draft Feasibility Study (Anchor QEA 2014). "
Excerpt: "Because it does not mention the TCRA armored cap, Region 6 also does not acknowledge that its preferred remedy for removal necessarily involves removal of that functioning cap – something that has never been done before and involves technical challenges and risks that were detailed in Respondents’ comments on Region 6’s Proposed Remedial Action Plan (Proposed Plan). "
"We strongly disagree with the proposed remedy put forth by the EPA. We are looking for the solution that best protects the environment and public health. We do not understand why the EPA would completely ignore their own consultant’s report, prepared by the Army Corp of Engineers, that concludes that removal of the wastes could significantly damage the environment and public health. It is disappointing that the EPA has apparently decided to ignore science and technical data. Excavation will result in resuspension of the material, worsening the river and putting nearby communities at risk for years to come. The Army Corps report and subsequent EPA-required testing around the site make clear that retaining and fortifying the cap – making it even stronger and permanent – is the best way to protect the river and surrounding communities. The sampling results demonstrate that no dioxin from waste is moving from the waste pits into groundwater below the pits or into surface water above the pits. We'll carefully review the EPA’s proposed remedy and maintain our focus on ensuring that the ultimate remedy fully protects public health and the environment. Together with the potentially affected communities and other groups interested in protecting the environment, we will work to make sure that the ultimate remedy follows the best science and technical data to protect the environment and citizens of Texas."
