Solid Waste Section Permit No.: 4 10 1 -MSWLF- 1979
Dear Mr. Coslett,
Both the Hazardous Waste Section (HWS) and the Solid Waste Section (SWS) of the Division of
Waste Management (DWM) appreciated meeting the stakeholders for the Seaboard Group II and
the City of High Point on August 2, 2023. This letter requests that the stakeholders prepare a
Workplan for sampling and initial testing of selected environmental media for Per- and
polyfluorinated Alkyl Substances (PFAS). Both the North Carolina Department of Environmental
Quality (DEQ) and the U.S. Environmental Protection Agency have prioritized the identification
and assessment of regulated sites that produce(d), utilized, or accumulated products that contain
PFAS. The product categories and waste types which may contain or release PFAS are many,
including but not limited to paints, coatings, water repellent fabrics, non-stick cookware, stain -
resistant fabrics and carpeting and food packaging.
The DWM is requiring the Former Seaboard Chemical and Riverdale Drive Landfill Site to
conduct PFAS monitoring in addition to the routine water quality monitoring beginning with the
Fall 2023 monitoring event. The sampled media must include groundwater from monitoring wells,
and surface water from surface water drainages that cross the property. From the August 2, 2023
meeting, the DWM understands that surface water sampling of Randleman Lake for PFAS is being
planned by the Piedmont Triad Water Authority. The Workplan must include sharing the results
of the surface water sampling with the DWM.

The DWM is requiring the samples to be analyzed using EPA Method 1633 for the full list of
PFAS compounds for the method. Please submit a PFAS monitoring work plan for Division
review as a Technical Memorandum since this is a change to the RASA.
Please contact us if you have any questions or concerns.
Sincerely,
