LaTonya,
Recommend you share these bullets with the senator and the two congressmen. We would hope to issue the fact sheet next month before going to Bridgeton for discussion and updates.
Pleaese call if you have questions.

West Lake Landfill Update-July 2012

Past actions include: signing the Record of Decision (ROD) in 2008. This decision included placing an engineered cover system over the radiologically-contaminated areas, long-term groundwater monitoring, and the adoption of institutional controls to restrict access. Action was conducted after holding numerous public meetings and comment periods.


After receiving numerous comments after the ROD was signed, EPA tasked the potentially.responsible parties (PRPs) to conduct a Supplemental Feasibility Study (SFS) to further evaluate: the ROD-selected remedy; and full.scale excavation of the landfill material.


The SFS was approved by EPA, released to the public in December 2011, and posted to EPA’s website.


The estimated costs defined in the SFS Report triggered a formal review by EPA’s National Remedy Review Board (NRRB).


The NRRB recommended that EPA Region 7: -Evaluate additional groundwater sampling to refresh the data; and

– Conduct a more detailed analysis of
potential treatment technologies for the
radiologically-contaminated landfill
material.


EPA Region 7 also decided to update the gamma scans ofthe OU-1 surface, and conduct vertical gamma scans of the site’s monitoring wells.


Timeline: (for EPA actiops) 1) Groundwater sampling -starting July 2012;

2) Gamma scan evaluation-starting August 2012;and
..

3) Additional studies-would be conducted, if and when warranted.
• EPA will host a public availability session near the end of2012 to provide data results and take questions about the next steps in the remedy-selection process.
