RE: Request to Cease Cadmium Monitoring at Anson Landfill
Permit # 0403-MSWLF-2010

Dear Mrs. Stanley:
On September 21, 2020 and September 22, 2020, approximately 631 tons of gypsum waste was
transported from American Zinc Products, LLC to Chambers Development Landfill (Anson) prior to
receiving TCLP analytical results for a composite sample. The analytical results indicated a Cadmium
concentration of 1.1 milligrams per liter (mg/L), which is above the hazardous waste standard of 1.0
mg/L.
In response to this incident, the State of North Carolina, Division of Waste Management Solid Waste
Section (Section), through a letter dated April 29, 2021, required Anson to complete the following:
1. Develop a Hazardous Waste Assessment Plan (HWAP), including a section that limits delivery
of material after sampling is complete and has been provided to landfill personnel.
2. Identify the location of the hazardous gypsum waste in the landfill and provide an assessment of
waste removal options and the management of the waste within the HWAP.
3. Add Section 5.0 LEACHATE MONITORING PLAN to the HWAP, which requires quarterly
sampling of the Phase 3, Cell 1 sump for Cadmium for 2 years and submit an addendum to the
Water Quality Monitoring Plan describing this additional characterization effort.
The characterization specified in item 3 above has been submitted to the Section via email from 2021
through 2023. Since the 2-year monitoring period has concluded, Anson is requesting to end the
Cadmium-specific sampling from the Phase 3, Cell 1 sump.
Feel free to reach me at [phone] or [e-mail] with questions or
comments.
