Re: Approval of Groundwater Assessment Report
Duke Energy Roxboro Steam Station
Industrial Landfill
7302‐INDUS‐1988
Person County
DIN 28027

Dear Ms. Witt,

The Solid Waste Section (Section) has reviewed the Groundwater Assessment Report (DIN 26992)
for the Industrial Landfill at the Roxboro Steam Station submitted by synTerra on September 28,
2016. The Section agrees with the findings outlined in the report regarding monitoring wells GMW‐
6 and GMW‐11. Further assessment is not necessary. However, the Section may request additional
groundwater assessment in the future.

If you have any questions, please do not hesitate to contact me via email
[e-mail] or phone (919) 707‐8253.

Sincerely,

Elizabeth S. Werner
Permitting Hydrogeologist
Solid Waste Section
