Re: Request for Concurrence - Bottom Ash Removal Plan
Permit No.: 1804-INDUS
Marshall Steam Station

Terrell, North Carolina 28682

Dear Mr. Frost,
Upon completion of the vegetation maintenance project on the western slope of the Dry Ash Landfill
Phase II (Dry Ash landfill) (Permit No. 1804-INDUS) in late August 2016, it was discovered that bottom
ash has eroded from the haul road and deposited at the toe of the landfill slope. As discussed via our
phone conversation on September 20, 2016, Duke Energy requests concurrence for removal of bottom ash
material from the toe of the Dry Ash Landfill including improvements to the bottom ash haul road,
located above the western slope of the Dry Ash Landfill.

The scope of work for the above activities is anticipated to be:

1. Installing erosion and sediment control measures
2. Removing ash along the toe of the slope
3. Restoring 24 inches of cover soil in areas where ash was removed or is exposed
4. Re-grading the bottom ash haul road towards the existing stormwater channel
5. Placing 24 inches of cover soil within the existing roadway
6. Constructing an aggregate roadway section
7. Seeding and establishing vegetation on disturbed areas
8. Restoring damaged edge of waste markers

Ash removed during activities listed above will be disposed in the on-site landfill, Industrial Landfill No.1
(1812-INDUS).

If there are any questions regarding this request, please contact me at [phone].

Respectfully Submitted,
