Re: July 2023 Groundwater Monitoring Compliance Report Forms
Elementis Chromium Castle Hayne Manufacturing Facility
Occidental Chemical Corporation SDR Permit No. WQ0001492
Castle Hayne, North Carolina
H&H Job No. OXY-004
Dear Sir or Madam:
On behalf of Glenn Springs Holdings, Inc. (for Occidental Chemical Corporation), Hart & Hickman,
PC (H&H) is submitting the attached Groundwater Quality Monitoring: Compliance Report Forms
(GW-59A and GW-59) and laboratory analytical report for groundwater samples collected during
July 2023 in accordance with the Occidental Chemical Corporation Surface Disposal of Residuals
(SDR) Permit No. WQ0001492 for the Elementis Chromium Castle Hayne Manufacturing Facility.
Under the terms of the SDR permit, groundwater within an established Compliance Boundary
(generally surrounding the Quarry as depicted in Figure 1) is monitored on a semi-annual basis (during
July and November) for chloride, total chromium, total iron, total nickel, pH, and total dissolved solids
(TDS).
Note that the chromium business of Elementis plc (including Elementis Chromium, LP) was purchased
by Yildirim Holding A.S. (a Dutch -Turkish industrial group headquartered in Istanbul and Amsterdam)
during January 2023, and the Facility is now being operated under the name American Chrome and
Chemicals, LLC (ACC). Legal obligations and contracts between Occidental and Elementis remain in
effect between Occidental and ACC.
Background Information
The facility is currently operating under a 1999 Corrective Action Plan (I -CAP) for remediation of
compounds of concern (COCs) in groundwater above standards by processes of natural attenuation
pursuant to 15A NCAC 2L .0106(l). The COCs addressed by the 1-CAP are chlorides, iron, pH, and
TDS. The objective of the 1-CAP is to reduce COC concentrations which exceed target cleanup
concentrations at or outside of the compliance boundary established in the SDR permit by natural
attenuation. The target cleanup concentrations for the COCs except total iron are the 2L standards.

Division of Water Quality
August 23, 2023
Page 2
For total iron, the target cleanup concentrations are background levels established under a now -expired
Special Order by Consent (SOC) agreement. Annual natural attenuation groundwater monitoring
reports are submitted to the NC Department of Environmental Quality (DEQ) Division of Water
Resources (DWR) to satisfy the 1-CAP monitoring reporting requirements.
The results of the July 2023 monitoring indicate COCs above 2L standards or background. Immediate
notification of elevated iron, chloride, and TDS concentrations and pH levels outside the 2L standard
range was not made to DWR after receipt of the analytical results because these conditions are already
known to DWR and are addressed under the 1-CAP. Immediate notification of elevated chromium in
well MW-24/CPW-4D was not made after receipt of the analytical results because this condition is
attributable to the Plant Process Area (PPA) of the site and is already known to DEQ. Chromium
impacts associated with the PPA are being managed under an Administrative Agreement (AA) for
Voluntary Assessment and Remedial Action under the Inactive Hazardous Sites Branch (IHSB)
Registered Environmental Consultant (REC) Program, DEQ ID NCD057454670. Because chromium
and nickel are not COCs in the 1-CAP, if chromium and/or nickel concentrations are detected above
the 2L standards in the compliance wells (other than chromium in well MW-24/CPW-4D), notification
is made to DEQ in accordance with the SDR permit.
July 2023 Non -Compliance SummgU
Results of analysis of the July 2023 SDR compliance monitoring event indicate total chromium was
detected slightly above the 2L standard of 10 micrograms per liter (µg/l) in compliance monitoring
well MW- I O/CPW- I OD (11.1 µg/1). Total chromium is not a COC which is being addressed by the 1-
CAP (discussed above). As shown in Figure 1, MW-10/CPW-IOD is located along the western
perimeter of Quarry Section 1. Residual solids generated by the Elementis Chromium Castle Hayne
Manufacturing Facility's wastewater treatment plant are currently disposed in Quarry Section 2, and
therefore not in the area of well MW-10/CPW-IOD. Prior to July 2023, total chromium was most
recently detected above the 2L standard in MW- I O/CPW- I OD during May 2019. Future detections (if
any) of total chromium in SDR Permit compliance samples collected from the well will be addressed
in accordance with Conditions I.1 and I.2 of the current SDR Permit.
In accordance with Condition IV.12 of the SDR permit, non-compliance notification for the July 2023
chromium detection in well MW-10/CPW-IOD was made to the DWR Wilmington Regional Office
on August 11, 2023. Based upon the fact that the chromium detection is only slightly above the
2L standard and that the SDR Permit includes a condition for addressing chromium and nickel
detections above 2L standards, DWR approved a request by H&H to not submit a non-compliance
notification report for the detection.

Notes
15A NCAC 02L.0202 Ground Water Quality Standard
2 Site -specific target cleanup concentrations for iron are included in the DWR-approved May 28, 1999 I -CAP for remediation of compounds of concern above standards by processes of natural
attenuation pursuant to 15A NCAC 2L .0106(I). The target cleanup concentrations for iron are background levels established under a now -expired Special Order by Consent (SOC) agreement.
The site -specific target iron levels in the I -CAP are: 3.3 mg/L for Lower Aquifer Wells, 7.3 mg/L for Upper Aquifer non -Fluvial Deposits Wells, and 10.4 mg/L for Upper Aquifer Fluvial Deposits
Wells. CPWAS, CPW-7S, and CPW-12S wells are classified as Upper Aquifer non -Fluvial Deposits Wells. The remaining Upper Aquifer wells are classified as Upper Aquifer Fluvial Deposits
Wells.
mg/L = milligrams per liter; pg/L = micrograms per liter; U = not detected at the associated reporting limit; "-" indicates not analyzed; NE = not established
J-flag indicates estimated concentration detected above the laboratory minimum detection limit and below the reporting limit
Bold concentration exceeds the groundwater standard (site -specific standard for iron)
Data for permit compliance samples collected during the last three years included in table
Only those analytes detected above a groundwater standard (site -specific standard for iron) in at least one sample are included in table
July 2022 MW-9/CPW-9D data presented in table are the laboratory reported MW-19/CPW-9S results, and vice versa. Based on previous data, it appears the reported data for each well was
reversed (potentially due to mislabeled bottles).
