The FERC site has been down since Friday night, and people are freaking out (and rightfully so!) that this is eating into the 45 day comment period. I was lucky that I got one of the FERC CD-ROMs with the DEIS files. Those files have been uploaded to our sister site http://pipeinfo.org on the front page.
If you have any issues downloading any of the files or think anything is missing, please let me know!
