Subject:Dan River Steam Station landfill, Permit No. 7906-INDUS
Attachments:2017-0227 - CCR BG Well.pdf
Elizabeth‐
Duke Energy would like to immediately install a background monitoring well pair at the Dan River Steam Station landfill,
Permit No. 7906‐INDUS. The well pair is intended for use as background groundwater monitoring for the Federal CCR
and NCDEQ programs at this facility. Attached you will find a drawing defining the location of the proposed well pair
(BW‐2S/D) in addition to the existing proposed background well location (GWA‐18D, installed as a part of the ash basin
assessment work) recently found to be dry.
Duke Energy intends to submit the entire CCR monitoring network for the landfill at a later date in addition to revised
monitoring well locations to the approved Water Quality Monitoring Plan.
Additionally, the Landfill permit was issued by the Department of Environmental Quality (DEQ) Solid Waste Section on
October, 2016. Attachment 3, Part IV, #11, states: “A licensed geologist must be present to supervise the installation of
groundwater monitoring wells.” Duke Energy requests, for the installation of the aforementioned well pair, a waiver
from the aforementioned requirement. A Professional Geologist (P.G.) familiar with the geology and layout of the
facility, and Water Quality Monitoring Plan, will be on call throughout drilling. A field technician, under the supervision
of the P.G., will be present throughout drilling. Attachment 3, Part IV, #17, states: “All well construction records and soil
boring logs for new wells must be submitted to the Solid Waste Section Hydrogeologist for review within 30 days of
completion". Construction records and boring logs require quality assurance prior to distribution with data gathering
and verification extending beyond 30 days from individual well installation. Duke proposes that construction records
and boring logs for the aforementioned wells be submitted to the Solid Waste Section Hydrogeologist in the pre‐
operational groundwater report as one project.
Please do not hesitate to contact myself or Melonie Martin with any questions or comments regarding this request.
Thanks‐
Kim
