Subject: RE: Lowering Primary Ash Basin
All,
Thanks for the help in planning and coordinating the partial dewatering of the Primary Ash Basin at Buck. Removing
approximately 5 ft of water will greatly aid us in the geotechnical and environmental exploration (drilling).
HDR and our drilling sub -contractors (AE Drilling and SAEDACCO) are meeting Dean Beaver on site today to look at
access points and will begin the development of a drilling plan. Having the Primary Basin lowered by the end of
September should work well with the drilling schedule.
Henry previously scheduled a Buck Ash Basin Closure update meeting for today (mid-morning) and I know that many of
you were on the invite list. Dewatering activities would be a good agenda item.
Thanks again and talk to you soon.

We will pull a log every other day. So Dean is changing schedule to match 9" every other day.
Thanks Mike

Fyi...I'm pretty sure the stop -logs in the discharge structures at cell 1 & cell 2 are 9" logs and cell 3 are 6" logs.

I have talked with Tim Russell and Alan Stowe and we are ok to start lowering the ash basin on 9/13/13. We plan on it
taking the ash pond down 1 foot and wait a day between removing stop logs. We will monitor water levels on all three
ash basins and look for any changes in the discharge. Dale Wooten and David Brown will be doing in process monitoring
during this process.
Here is the plan for lowering basin. We would like to remove the logs first think after pre job at the start of the morning
shift. If needed we will take whatever time needed to settle the basins between each lowering.
Friday - 9/13/13 remove stop logs to lower basin 1 foot.
Weekend --9/14 and 9/15 settle out ash basin
Monday - 9/16/ 13 remove stop logs to lower basin 1 foot
Tuesday — 9/17/13 settle out ash basin
Wednesday — 9/18/13 remove stop logs to lower basin
Thursday — 9/19/13 settle out ash basin
Friday — 9/20/13 remove stop logs to lower basin
Weekend 9/21 and 9/22 settle out ash basin
Monday 9/23/13 remove stop logs to lower basin
Tuesday and Wednesday 9/24 & 9/25 basin to settle at level needed.
After basin has been lowered, we will need to see plan telling us how and when you will be doing the drilling inside the
primary ash basin.
Thanks
