History: This message has been replied to.
I am attaching the revised Westlake Fact Sheet that you have each weighed in on. I have made most of the changes you recommended, but updated to reflect your preferences, using some slight modifications, i.e., in one paragraph, you want the statement, “the decision selected ….. “-decisions don’t select, people do -so that’s an example of something that keeps the same reference context, but modifies the grammatical tone.
I would like to put this through concurrence in the next day, and I know LaTonya would like to use in her call to Sen. McCaskill’s office tomorrow, so please look over. I am not tied to anything in particular, but want to keep the tone consistent with the use of verbs 🙂

Region 7 Fact Sheet

Nine Tribal Nations July 2012
Update on Activities Supporting the Record of Decision (ROD)
Amendment for the Westlake Landfill Superfund Site
Bridgeton, Missouri

The U.S. Environmental Protection Agency (EPA) Region 7 has been working in the Bridgeton community to address environmental issues at the Westlake Landfill over a multi-year period. The Westlake Landfill is comprised of two (2) operable units (OUs). OU-1 contains a mixture of radiologically-contaminated soils, municipal refuse and construction/demolition debris. OU-2 includes several sanitary landfill cells containing municipal refuse and construction/demolition debris.
After conducting extensive investigations, holding numerous public forums, and responding in detail to public comments, EPA signed a Record of Decision (ROD) for QU-lin May 2008. This decision document outlined the selected remedy, which included the placement of an engineered cover system over the radiologically-contaminated areas, long-term groundwater monitoring, and the adoption of institutional controls to restrict access.
After the ROD was signed, EPA continued to receive public comments about the selected remedy. In response to those comments, EPA tasked the potentially-responsible parties (PRPs) to conduct a Supplemental Feasibility Study (SFS) for OU-1 that further evaluated the ROD-selected remedy, as well as full-scale excavation of the radiologically.contaminated landfill material and disposal either at a permitted off-site facility or in a new, on-site engineered disposal cell.
The SFS Work Plan was released to the public in June 2010. After reviewing several draft versions of the document, EPA approved and released the SFS Report to the public in December 2011. The estimated costs defined for each alternative in the SFS Report exceeded the threshold, which triggered a formal review and evaluation by EPA’s National Remedy Review Board (NRRB). Between January 2012 and the present time, the NRRB has weighed in with numerous draft comments and recommendations on the SFS Report. The NRRB recommended that EPA, Region 7: evaluate additional groundwater sampling to refresh the data; conduct a more detailed study of the partial excavation alternative; and conduct a more detailed analysis of potential treatment technologies for the radiologically.contaminated landfill material. EPA, Region 7, then tasked the PRPs to conduct some ofthis work as an amendment to its original Consent Order.
In response to more general NRRB recommendations, EPA, Region 7 also decided to update gamma scans ofthe surface ofOU-1 and conduct vertical gamma scans ofmonitoring wells at the site. EPA, Region 7 will perform the gamma scans.
The work will be conducted by PRPs under EPA
oversight, with the following proposed 2012/2013
July ’12 -Groundwater sampling (PRPs to conduct, EPA & MDNR will take splits);
August’ 12-Gamma scan evaluation to further rtrfine distribution of radiologically-impacted wastes (EPA staffto conduct);
Summer ’12-’13 -Additional studies to address the NRRB draft comments. (PRPs to perform).
In coordination with its stakeholders, EPA will host a public availability session near the end of2012 in Bridgeton to: convey updated data results; discuss the scope ofthe PRP additional studies; and take questions about the next steps in the ROD.Amendment process.
