Re: Remedial Action Progress Report, 2023 Fourth Quarter and Annual Summary
Former Seaboard Chemical and Riverdale Drive Landfill Site
Jamestown, Guilford County, North Carolina
Dear Mr. Aufderhaar:
The Seaboard Group II and the City of High Point are providing this 2023 Fourth Quarter and
Annual Summary Remedial Action Progress Report for the former Seaboard Chemical
Corporation facility and the closed Riverdale Drive Landfill located in Jamestown, NC.
System Operations — Performance
During the fourth quarter of 2023, the mechanical and phytoremediation treatment systems
processed 3,838,262 gallons of extracted groundwater and leachate. The summary of treatment
flow volume by calendar quarter is provided on Figure 1 of this report and below:

The mechanical treatment system operated continuously during 2023 with minor shutdowns
occurring for routine maintenance, system citric cleaning, and repairs. The runtime hours of the
mechanical treatment system during 2023 is summarized on Figure 2 of this report and below:

Based on the average influent concentrations during the fourth quarter of 2023, approximately
589 pounds of volatile organic compounds and 28.8 pounds of 1,4-dioxane were removed by the
groundwater extraction and leachate collection systems. The total contaminant mass removed by
the remedial systems during 2023 is summarized below:

System Operations — Shutdowns
During the fourth quarter of 2023, three shutdowns exceeding one day in length occurred. The
system was shutdown for 2.7 days on September 30, 2023 for an air valve issue, 2.0 days on
October 7, 2023 for overloaded filter pressures, and 2.7 days on December 1, 2023 for a system
programming issue. No other significant shutdowns occurred during this reporting period.
During the 2023 calendar year, the system was shutdown for several planned and unplanned
events. While past Quarterly Progress Reports have provided shutdowns in excess of one day in
duration, this Annual Summary includes all shutdowns regardless of duration. A summary of all
planned and unplanned shutdowns which occurred in 2023 is provided on Figures 3 and Figure 4
of this report and on the table below:

The shutdowns attributed to service/upfit (16.6 days) and approximately 25% of the mechanical
shutdowns (4.5 days) were planned events for routine cleaning and/or equipment maintenance.
These routine activities accounted for 42.4% of the shutdowns during calendar year 2023.
System Operations - Monitoring
As recommended in the October 2023 Technical Memorandum 11 Final Summary Report, a
limited quarterly groundwater and surface water monitoring program has been implemented.
This quarterly monitoring program was approved by NCDEQ on November 3, 2023. This

limited monitoring program includes the on -site surface water monitoring locations (SW-1, SW-
2, SW-3, SW-4, and SW-5) and two monitoring wells at the SIS Basin Area (AW-3/4B).
Due to heavy rainfall during the last week of December 2023, these samples were collected on
January 3, 2024. A summary of the laboratory analytical results for the surface water and
groundwater samples is provided on the attached table and the full laboratory report is included
with this Progress Report. The information provided by this limited quarterly monitoring
program will allow for a continued evaluation of the expanded extraction system and overall
remedial system operation.
Please contact Craig Coslett (610/435-1151) or Gary Babb (919/605-4719) if there are any
questions or comments regarding this update.
