RE: 2023 Annual Report
American Chrome and Chemicals Castle Hayne Manufacturing Facility
(Formerly Elementis Chromium Castle Hayne Manufacturing Facility)
Surface Disposal of Residuals
Permit No. WQ0001492
Castle Hayne, New Hanover County, North Carolina
Dear Sir or Madam:
Occidental Chemical Corporation and American Chrome and Chemicals have prepared this 2023
Annual Report in accordance with the requirements of the NC Division of Water Resources
(DWR) Instructions for Residuals Application Annual Reporting Forms and the permit specific
conditions of Surface Disposal of Residuals (SDR) Permit No. WQ0001492.
The SDR Permit holder is Occidental Chemical Corporation, located at 5 Greenway Plaza, Suite
110, Houston, Texas 77046. The residuals generator/preparer is American Chrome and
Chemicals, located at 5408 Holly Shelter Road, Castle Hayne, North Carolina 28429. The SDR
Permit identifies the facility by the name Elementis Chromium Castle Hayne Manufacturing Facility.
During January 2023, Elementis Chromium, LP was purchased by Yildirim Holding A.S., and the
Facility is now being operated under the name American Chrome and Chemicals.
The following items are included in this submittal:
• Form DMSDF: Class A Annual Distribution and Marketing/Surface Disposal
Certification and Summary Form;
• Form RSSF: Annual Residual Sampling Summary Form;
• Form RSSF — B: Annual Residual Sampling Summary Form — B;
• Monthly Total Metals Laboratory Analytical Reports;
• Weekly Chromium TCLP Laboratory Analytical Reports;
• Laboratory Analytical Report for Demonstration that Residuals are Non -Hazardous
(i.e., TCLP, Ignitability, Reactivity, and Corrosivity); and,

• Summary of Affected Wells and Facility Map.
Residuals were not deposited in Quarry 1 Section I (QS 1) during 2023. It is estimated that
53,164 dry tons of residuals were deposited in Quarry 1 Section H (QS2) during 2023.
Collectively, QS 1 and QS2 are permitted for a maximum of 171,000 dry tons per year.
Based on the previous residual loading into QS 1, the estimated volume of residuals contained in
QS 1 is 3,747,306 cubic yards. The estimated remaining capacity of QS 1 is 625,000 cubic yards,
which equates to approximately 3.4 years at the maximum loading rate.
The total estimated weight of residuals deposited into QS2 during 2023 was 53,164 dry tons. As
of December 31, 2023, the estimated cumulative residual volume contained in QS2 was
3,241,804 cubic yards. The estimated remaining capacity on this date was approximately
425,738 cubic yards. Based on these estimates, the estimated remaining useful life of QS2 is 2.3
years at the maximum loading rate.
While chromium ceiling concentrations presented in Condition II.6 of the permit were exceeded
for the entire reporting period, residuals were determined to be non -hazardous. As noted in
Condition H.6, "Residuals that exceed the ceiling concentration for chromium may be disposed
of in the surface disposal unit as long as they are determined to be non -hazardous under RCRA
with respect to chromium leachability as stipulated in Condition IV.2 and as long as the
groundwater monitoring program as stipulated in Attachment C of this permit demonstrates that
the surface disposal unit is not causing the assigned groundwater quality standards to be
violated."
Residuals generated were analyzed with respect to chromium leachability on the following
sampling schedule:
a. Grab sample — once per week
b. Composite sample — once per week
Based upon Toxicity Characteristic Leaching Procedure (TCLP) analytical results, residuals
disposed during the reporting period were determined to be non -hazardous under RCRA as
stipulated in permit Condition IV.2 and IVA. A residuals sample collected on July 19, 2023 was
analyzed to demonstrate the residuals are non -hazardous under RCRA per the requirements of
permit Condition IV.2, and residuals were analyzed for TCLP chromium on a weekly basis
during the reporting period to demonstrate they are non -hazardous under RCRA with respect to
chromium per the requirements of permit Condition IVA. TCLP sample analytical reports are
attached to this report.
Non -Compliance Summary
Under the terms of Occidental's SDR Permit, ground water within an established compliance
boundary around the Quarry, along the eastern perimeter of the Facility, and along the northern

CHROME & CHEMICALS
perimeter of the Closed Former Lagoon, is monitored for compliance with the 15A NCAC 02L
.0202 ground water standards (21, standards) or background, whichever is higher, on a semi-
annual basis (in July and November). Ground water samples collected during the SDR
monitoring events are analyzed for chloride, total chromium, total iron, total nickel, pH, and total
dissolved solids (TDS), and results of each compliance monitoring event are submitted to DWR
on Forms GW-59 and GW-59a in accordance with the requirements of the SDR Permit. On the
attached Form DMSDF, the facility is noted as being out of compliance due to detections of total
chromium and TDS above North Carolina 2L standards, total iron above site -specific
background levels, and pH outside of the 2L standard range in groundwater samples collected
during 2023 from one or more of the SDR Permit compliance monitoring wells. With the
exception of the detections of total chromium above the 2L standard, the 2023 ground water
quality standard contraventions noted above are consistent with conditions which are already
known to DWR and are being addressed by processes of natural attenuation in accordance with
the Corrective Action Plan dated May 28, 1999 (CAP) which was approved by DWR on
July 28, 1999. Therefore, immediate notification of these detections was not made to DWR.
During 2023, total chromium was detected slightly above the 2L standard (0.01 milligrams per
liter — mg/L) in two of the 2023 SDR compliance monitoring samples (0.0111 mg/L in the
July 2023 MW-10 sample and 0.011 mg/L in the November 2023 MW-18 sample). The
detections of chromium above the 2L standard in these two wells are anomalous occurrences
based on the low frequency of previous total chromium detections above the 21, standard in the
wells. DWR was notified of the chromium detections as required by the SDR Permit. As
discussed with DWR, no additional evaluation of the anomalous total chromium detections will
be completed prior to the SDR Permit compliance monitoring event during July 2024, and future
detections (if any) of total chromium in SDR Permit compliance wells will be addressed in
accordance with Conditions I.1 and I.2 of the SDR Permit.
Total chromium was also detected above the 21, standard in samples collected from MW-24
during 2023; however, elevated chromium in MW-24 is attributable to the plant process area
(PPA) of the facility, is already known to DEQ, and 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. Total chromium was not detected above
the 2L standard in any other SDR Permit compliance wells during 2023.
Results of analysis of groundwater samples collected from SDR Permit compliance monitoring
wells during 2023 are summarized in the Summary of Affected Wells table attached to this
report and SDR Permit compliance well locations are depicted in the attached Facility Map.

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 mg1L 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. CPW-1 S, 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.
mg1L = milligrams per liter; pg/L = micrograms per liter; U = not detected at the associated reporting limit; 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)
