Steve and Joyce -
Regarding the backfill:
Given the depth of the coal ash, I do not believe sufficient hydric soil exists on-site (specifically in the project area or on
Dan River proper) to backfill with hydric soil. Certainly, reasonably clean hydric soil removed during the coal ash
excavation process will be used/placed back as part of the backfill. There is evidence to suggest a quality top soil with
sufficient organic component is as good as the hydric soil with regard to fungal -bacteria plant vigor relationship when
restoring or crating wetlands. (We have a suggested organic soil component specification, we are hunting it
down). Hence, native soil means a quality top soil with added organic component for the backfill. If there is a sufficient

quantity of hydric soils , then the last two to three inches of backfill (more depth if quantity exist) would/will be
composed of the remnant hydric soil. A major key in restoring the wetland area is maintaining hydrological
connectivity, which means avoiding soil compaction!
Coir Fiber Matting (I apologize we should have indicated that the matting is to be biodegradable):
The coir fiber matting used is to be biodegradable. The velocity of water moving through the wetland and stream
complex area does not suggest the need for re -enforced matting.
Let me know if this answer meets your needs.
Please call me as necessary.

Joyce/Steve,
I have two questions about the narrative. You state that the excavated area will be backfilled with native soil, do you
mean native hydric soil? You mention using coir fiber matting within the wetland, the Division would typically require
that the any matting used in wetlands or along streambanks for stabilization be completely biodegradable (no nylon
webbing), if this won't be feasible we'd need you to provide more details of what you intend to use and why you can't
use biodegradable matting.
Thanks,

David and Sue,
I am sending the letter and graphic concerning the ash removal from Wetland D at Dan River for the Stormwater
Diversion for your review for approval. The project scope is the removal of ash from Wetland D discovered during
clearing of the dredge pool.
Thank you in advance for your review and consideration. Please let me know if you have questions or need additional
information.
