RE: 2022 Annual Report
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 Elementis Chromium have prepared this 2022 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 Elementis Chromium, Inc.,
located at 5408 Holly Shelter Road, Castle Hayne, North Carolina 28429.
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.

CHROMIUM
Residuals were not deposited in Quarry 1 Section I (QS1) during 2022. It is estimated that
79,643 dry tons of residuals were deposited in Quarry i Section II (QS2) during 2022.
Collectively, QS I and QS2 are permitted for a maximum of 171,000 dry tons per year.
Based on the previous residual loading into QS1, the estimated volume of residuals contained in
QS1 is 3,747,306 cubic yards. The estimated remaining capacity of QS1 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 2022 was 79,643 dry tons. As
of December 31, 2022, the estimated cumulative residual volume contained in QS2 was
3,168,665 cubic yards. The estimated remaining capacity on this date was approximately
498,877 cubic yards. Based on these estimates, the estimated remaining useful life of QS2 is 2.8
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 II.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 Conditions IV.2 and IVA. A residuals sample collected on August 3, 2022
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.

CHROMIUM
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
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, total iron, and TDS above North Carolina 2L standards (above background for total
iron), and pH outside of the 2L standard range in groundwater samples collected during 2022
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 2022 ground water quality standard
contraventions noted above 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.
During July 2022, total chromium was detected above the 2L standard in three SDR permit
compliance wells MW-14, MW-17, and MW-18. During August 2022, these three wells were
resampled to further evaluate the July 2022 chromium detections, and total chromium was not
detected in any of the August 2022 samples. In addition, total chromium was not detected in
November 2022 samples collected from the wells. Based on the August and November 2022
sample results and a review of previous total chromium data for the wells, the July 2022 total
chromium detections above the 2L standard in these three wells is an anomalous occurrence.
During November 2022, total chromium was detected above the 2L standard in compliance well
MW-19. Based on the low frequency of total chromium detections above the 2L standard in
samples collected from MW-19 prior to November 2022 and the long period of time since total
chromium was previously detected above the 2L standard in the well, the November 2022
detection of total chromium above the 2L standard in MW-19 is an anomalous occurrence. Non-
compliance reports were submitted to DWR in accordance with requirements of the SDR permit
for the 2022 total chromium detections above the 2L standard discussed above. No additional
evaluation of the anomalous total chromium detections will be completed prior to the SDR
permit compliance monitoring event during July 2023, and future detections (if any) of total
chromium and/or nickel in SDR permit compliance wells will be addressed in accordance with
Conditions I.1 and I.2 of the SDR permit (which include provisions for possible submittal of a
Comprehensive Site Assessment and amendment of the 1-CAP if certain criteria are met).
Total chromium was also detected above the 2L standard in samples collected from MW-24
during 2022; 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 2022.
Results of analysis of groundwater samples collected from SDR permit compliance monitoring
wells in the period between July 2020 and November 2022 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 DW R-aPIP roved May 28, 1999 I -CAP for rem ediation 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. 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.
mg/L = milligrams per liter; pg/L = micrograms per liter; U = not detected at the associated reporting limit
-" indicates not analyzed; FF = field -filtered sample; NE = not established
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 an alytes 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 mislabeIed bottles).
"value is field -measured pH value adjusted by adding 1.25 s.u. (see report for discussion)
