SEABOARD GROUP II AND THE CITY OF HIGH POINT February 26, 2018 Mr. Joe Ghiold, Project Manager North Carolina Department of Environmental Quality Division of Waste Management 1646 Mail Service Center Raleigh, North Carolina 27699-1646 Re: Quarterly Remedial Action Progress Report, 4th Quarter 2017 Former Seaboard Chemical and Riverdale Drive Landfill Site Jamestown, Guilford County, North Carolina Dear Mr. Ghiold: The Seaboard Group II and the City of High Point, NC (Parties) are providing this 4th Quarter 2017 Remedial Action Progress Report for the former Seaboard Chemical Corporation facility (SCC) and closed Riverdale Drive Landfill (Landfill) located in Jamestown, NC (the Site). During the 2017 calendar year, the mechanical and phytoremediation treatment systems processed 8,574,00 gallons of extracted groundwater and leachate. During the 4th Quarter 2017, the following shutdowns exceeding one day in duration occurred: Date Duration Reason for Shutdown November 4, 2017 2.2 days Power Failure November 11, 2017 1.8 days PW-DR1 Pump Failure November 14, 2017 1.9 days PW-DR1 Pump Repairs December 1, 2017 5.0 days P-601 A&B pumps cleaned/de-scaled December 11, 2017 4.0 days Routine citric acid system cleaning As discussed in the 3rd Quarter 2017 Report, the Parties have evaluated response actions to protect the system electronics from future lightning strikes and other power fluctuations. This evaluation was taken in response to the 55 day shutdown which occurred due to a lightning strike on June 19, 2017. The entire system has been inspected by an electrical contractor and the Parties have received recommendations for upgrades to the surge suppression and UPS backup systems. The Parties are in the process of implementing the approved recommendations and these activities should be completed during the 1st Quarter of 2018 . The attached Figures and Tables provide the results of the full scale operation of the treatment System during the 4th Quarter 2017, including: Operating Data, Process Flow Data, Well Static Water Level Data, System Chemistry, Utility Data Use, and Contaminant Removal Efficiency. Summary At this time, the system is in full operation. Recommendations to upgrade the electrical surge suppression and UPS backup systems have been approved and in the process of implementation. Please contact Mr. Gary D. Babb, P.G. (919/325-0696) or Craig Coslett (610/435-1151) if there are any questions or comments.
