Event Title: Rogers CCP Landfill Leachate Release
Report Date: October 13, 2017
Submitted to: NCDEQ Division of Waste Management (DWM)
Regulatory agency contact: Shawn McKee 919-707-8284
Duke Energy contact: Ryan Czop 980-373-2779

Permit No.: 8106-INDUS

1. Event Description
a. Date: discovered Sunday October 8, 2017 at approximately 11:32 pm
b. Material released
(Yes/No). Description if yes: landfill leachate
c. Summary:
• On the evening of October 8, 2017 the landfill leachate pumps lost power due to a
rainstorm event.
• Leachate accumulated within Phase II of the landfill, causing the pressure on the
perimeter slope to increase. A small stream of leachate was released from
approximately 11:30 pm on October 8, 2017 until 2:00 am on October 9, 2017. The
stream was clear with no visible ash.
• The leachate stream traveled into the undeveloped Phase III area where it mixed
with ponded rainwater. That area discharges into Sediment Basin 2, which
discharges into a ditch that eventually flows into Suck Creek.
• AMEC was hired to determine the volume of leachate water that may have been
released off-site. Their evaluation concluded that 150 gallons was released off-site.
d. Field actions:
• The landfill leachate pumps were returned to service within one hour of power being
lost.
• The leachate release was stopped by compacting the soil at the release point on the
perimeter slope.
• The SB-2 skimmer was lifted to reduce the discharge flow.
• At SB-2, sand bags were placed around and at the end of the exit pipe to divert
water back into SB-2 with a pump. Water was pumped from SB-2 to the landfill
leachate basin. The pumping continued until virtually all water was absent from SB-
2.
• Water was pumped from the Phase III landfill area to the leachate basin.
• Samples were taken from four locations and analyzed for the parameters in the
landfill Water Quality Monitoring Plan. Those results are provided as an attachment
to this report as well as a map of the sampling locations.

• Secondary- Larry Frost 828-296-4704

Summary:
Phone conversation with both Shawn and Larry describing discovery of the
leachate release and field actions taken. At the time of the phone conversations
it was unknown if leachate was released off-site. A site inspection was not set up
during the discussions. Ted Campbell of NCDEQ DWR contacted Ryan Czop at
approximately 3:00 pm to set up a site visit the following day (October 10) at 10
am. Larry Frost followed up later that afternoon via email that he will be
attending the visit as well.
b. Date and time of additional regulatory agency contact:
Monday October 9, 2017 at approximately 2:00 pm
Regulatory agency: NCDEQ Division of Water Resources NPDES Section
Contact name: Landon Davidson contacted by Robert Wylie (Duke)
Summary:
Phone conversation to report that leachate from the landfill was released.

3. Regulatory Site Visit
Was a regulatory visit conducted (Yes/No)
a. Date and time of site visit:
October 10, 2017 arrival time: 10:00 am, departure time: 11:15 am
b. Regulatory agency: NCDEQ DWM and DWR
c. Attendees: Larry Frost, Ted Campbell, Tim Heim
d. Duke Energy escort(s): Tim Hill, Jessica Snyder, Ryan Czop, Robert Wylie, Wade
Hollifield
e. Areas inspected:
• Southeast corner of Phase II at location of leachate release
• Phase III inlet and outlet
• Sediment Basin 2
• South of railroad tracks near property line
• Leachate Basin
f. Records reviewed: None
g. Issues indicated: None

4. Regulatory Recommendations:
• DWR requested a five day follow up letter.

• DWM also expected a written follow up report.
• If any investigative work is proposed at the location of leachate release DWM requested
a plan prior to completing any work.

5. Duke Energy Follow-Up Actions:
• The area of leachate release will be evaluated.
• The power loss will be evaluated.
• If any investigative work is proposed at the landfill a plan will be communicated to DWM.
