Routine Water Sampling Change
The Environmental Protection Agency, and the Tennessee Department of Environment and Conservation, have agreed to allow TVA to reduce the routine water sampling in the Settling Basin and Stilling Pond at the Kingston Ash Recovery Project to once a month rather than once a week. Samples will still be taken on a weekly basis in the Clean Water Ditch. Each location will be tested for total suspended solids and ash-related metal constituents. Sampling will continue at the Stilling Pond until closure of the Dredge Cell and ash pond are complete. Automated sampling at the Swan Pond Embayment will continue to be triggered by rainfall of equal to, or greater than, a half an inch in a 24-hour period.
Since the removal of ash from the North Embayment, there has been a reduction in the concentration of ash-related material entering the Emory River from the Swan Pond Embayment, and incidents of exceeding water standards have decreased.

TVA/EPA Workshops
The third of six public workshops to discuss the upcoming Engineering Evaluation/Cost Analysis (EE/CA) was held on April 19, 2012, at Roane State Community College. Information was presented on aquatics results: sediment toxicity tests, mayflies, snails and fish.
In the next workshop on May 3, 2012, data will be presented from birds, turtles, mammals, and plants. As before, this workshop will be held at Roane State Community College, 276 Patton Lane, Harriman, TN 37748 at 6:30 – 7:30 p.m. in the Walden Ridge Dining Room off the main cafeteria. Signs will be placed in the cafeteria directing attendees to the location.
Presentations can be found on our website at http://www.tva.gov/kingston/presentations/river-eeca/index.htm the next day following each workshop.
April 13, 2012
This week, we’re sending some recent photos that encompass the work being done at the Kingston Ash Recovery Project. The usual information on ash removal and perimeter wall progress is also included.
The photo below shows excavation in the Middle Embayment in the foreground, and work continuing on Segment 8 of the Perimeter Wall Stabilization (PWS) in the background. As of April 8, 2012, 42% of the ash was removed from the Middle Embayment. As of April 10, 2012, approximately 31% of the PWS was completed. Work will continue on Segments 7 & 8.
Below, work is progressing on the buttress being applied to portions of Segment 1 of the PWS. The buttressed section of Segment 1 will be next to the water when the Middle Embayment is refilled. In the background, ash is being stacked in the dredge cell which will be closed and capped.
Below, looking across the East Embayment is the Lakeshore Drive area that will become a green space/recreational area.
This view from the overlook shows the ash stacking in the central dredge cell. A kiosk is being installed at the overlook that will show an aerial view of the Kingston Ash Recovery Project with descriptions of various areas around the site, as well as current work being done.

Kiosk Highlighting Recovery Efforts to be Installed at Overlook Area
TVA will install a kiosk at the overlook located on the hill across from the recovery project site that will contain updates on the progress of work at the site. The overlook is an area designated for interested members of the public to view the ongoing restoration efforts at the site. A sign at the road indicating the location of the overlook area will also be installed.

The slides will be available on the TVA website (http://www.tva.gov/kingston/presentations/river-eeca/index.htm) following each workshop.
Perimeter Wall Stabilization (PWS)
As of March 31, 2012, the PWS was 30% complete. Work on segments 7 and 8 continues. In addition, TVA is reinforcing the PWS by applying a buttress between the shear walls on parts of Segment 1A. In the photo on the left, workers clear between the shear walls so the buttress can be put in place. The photo on the right shows the buttress in place between portions of the shear wall.
Easter Weekend
Limited work will be conducted at the recovery project site during Easter weekend. Normal work will resume on Monday, April 9.

Workshops
The second of six workshops will be held at Roane State Community College, 276 Patton Lane, Harriman, Tennessee, on Thursday, April 5, 2012, at 6:30 – 7:30 p.m., in the Walden Ridge Dining Room. The subject of the upcoming Workshop is “Nature and extent of residual ash in the River System & Fate/Transport Modeling.” The dates and subjects for the remaining workshops are as follows:
- April 19, 2012: Workshop 3 - Presentation of data from fish, birds and frogs
- May 3, 2012: Workshop 4 - Presentation of data from benthic macro-invertebrates, turtles, mammals, and plants
- May 17, 2012: Workshop 5 - Ecological Risk Assessment process and development of General Response Actions
- June 7, 2012: Workshop 6 - Evaluation of Removal Alternatives
- Orange paint or flag: Trees/shrubs are to be removed and discarded. Most of these are non-native or invasive species.
- Green/blue paint or flag: Trees/shrubs are to be saved and stockpiled for shoreline stabilization (large trees with root ball intact) and fish habitat structures (shrub, tree canopies, etc---essentially brush piles weighted down and placed in specific, strategic locations in the water of the Lakeshore Emory River and East Embayment areas. Most of these trees and shrubs are non-native species; some are marked because of overcrowding or large trees that are diseased and pose a threat in a public use area (split trunks, widow-maker limbs, etc).
- TVA’s current focus is to remove the orange flagged species.

TVA would like to remind everyone who travels along Swan Pond Road near the worksite to be aware of the ongoing work, to drive safely, and be careful not to be distracted by the heavy equipment working in close proximity to the road. No traffic delays are expected.
February 28, 2012
New Sampling Location for the Clean Water Ditch/Middle Embayment Area
Progress in the middle embayment has translated into the need to remove the road that crosses the clean water ditch in the middle embayment area between the Settling Basin Effluent and the Embayment Auto Sampler. This means we will also need to remove the existing sampling platform next to the culverts.
TVA proposes moving the sampling location as indicated on the attached photograph, and collecting grab samples and ISCO samples representative of the embayment from the proposed new location in the future.
Proposed Middle Embayment Sampling Location

Emergency Sirens to be Tested
The TVA Kingston Fossil Plant will conduct a brief test of its emergency sirens at the plant on Thursday, February 16, about 12:30 p.m. EST. The sirens may be loud enough to be heard outside the plant boundaries. This is only a test. The sirens are used to notify plant personnel in the event of a chemical release at the plant. TVA routinely conducts training and drills at Kingston and other fossil plants where chemicals are stored, to ensure proper procedures are followed if a spill or release of the materials were to occur onsite. TVA also works with local Emergency Services personnel. Notice of the test should appear in the Roane County News.
