Newly released is the preliminary design report for the bypass channel (PDF) of the Clark Fork River through the Milltown Reservoir Superfund site. This is a critical piece to the removal of more than two million cubic yards of contaminated sediments in the reservoir and hauling them to the BP/ARCO repository near Opportunity. The report presents the preliminary designs for the bypass channel excavation, dewatering/water management, berm construction, sediment stockpiling and more. It also includes a preliminary construction schedule.

A design review team meets Tuesday, July 25 to discuss the report. A special review committee will also be convened to look at how the bypass will affect fish passage for the threatened bull trout. Check back soon for CFRTAC’s comments.

The report with all the appendices is also available at Envirocon’s FTP site.
Here’s how to download a copy of the report:

Click on the following link ftp://public:This email address is being protected from spambots. You need JavaScript enabled to view it./ and an ftp session should open in your internet browser (e.g. Internet Explorer, Netscape, etc).

You should see the folder “Stage 1C Element 1 PDR”. Open this folder and the various PDF files making up the report will appear. Because of their large file size, report appendices are provided as separate PDF files to reduce download time for those only interested in certain portions of the report.

Drag and drop the desired files from the ftp window to your desktop (or other directory where you would like the files to reside) and allow them to download to your computer.

Do not attempt to open the files directly from the ftp window.

If you have any problems downloading this file call Zac Collins in EMC2’s Bozeman office at 406-522-0251 for technical support.
