RE: 2020 Annual Report
Elementis Chromium Castle Hayne Manufacturing Facility
Surface Disposal of Industrial Byproducts Residuals
Permit No. WQ0001492
Castle Hayne, New Hanover County, North Carolina
Dear Sir or Madam:
Occidental Chemical Corporation and Elementis Chromium have prepared this 2020 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 Industrial Byproducts Residuals (SDIBR) Permit
No. WQ0001492.
The SDIBR 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 (QS 1) during 2020. It is estimated that
85,322 dry tons of residuals were deposited in Quarry 1 Section II (QS2) during 2020.
Collectively, QS 1 and QS2 are permitted for a maximum of 17 1, 000 dry tons per year.
Based on the previous residual loading into QS 1, 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 estimated capacity
of QS 1 was adjusted based on a hydrographic survey conducted in December 2020.
The total estimated weight of residuals deposited into QS2 during 2020 was 85,322 dry tons. As
of December 31, 2020, the estimated cumulative residual volume contained in QS2 was
2,943,066 cubic yards. The estimated remaining capacity on this date was approximately
725,000 cubic yards. Based on these estimates, the estimated remaining useful life of QS2 is 4.0
years at the maximum loading rate. The estimated capacity of QS2 was adjusted based on a
hydrographic survey conducted in May 2019. In addition, Martin Marietta, Inc. did not dispose
of any residuals or limestone tailings from their adjacent mining operation into either section of
the surface disposal unit during 2020.
While chromium ceiling concentrations presented in Condition H.8 of the permit were exceeded
for the entire reporting period, residuals were determined to be non -hazardous. As noted in
Condition 11.8, "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) chromium analytical results for
residuals samples, residuals disposed during the reporting period were determined to be non-
hazardous under RCRA with respect to chromium leachability as stipulated in permit Condition
IV.2. TCLP sample analytical reports are attached to this report.
Under the terms of the SDIBR permit, groundwater within an established Compliance Boundary
is monitored for compliance with the 2L standards on a semi-annual basis (in July and
November). Groundwater samples 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
SDIBR permit. On the attached Form DMSDF, the facility is noted as being out of compliance
due to detections of total iron, total nickel, and TDS above North Carolina 2L standards, and pH
outside of the 2L standard range in groundwater samples collected during 2020 from one or more
compliance monitoring wells which are sampled in accordance with the SDIBR permit. With the
exception of detections of total nickel above the 2L standard in one monitoring well, the 2020
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 the NC Department of Environmental Quality on July 28, 1999. The
2020 Annual Quarry Natural Attenuation Ground Water Monitoring Report dated February 26,
2021 was submitted to DWR to document the methods and results of groundwater monitoring
completed during 2020 to satisfy CAP monitoring.
Total nickel was detected in the July and November 2020 samples collected from MW-17/CPW-
7S at 228 and 723 micrograms per liter (µg/1), respectively, versus the 2L standard of 100 µg/l.
MW-17/CPW-7S is located along the eastern perimeter of Quarry Section 1 between the Plant
Process Area (PPA) of the site and the Quarry. Note that compliance monitoring samples have
been analyzed for nickel during only those monitoring events completed after issuance of the
SDIBR permit in November 2016, and nickel was detected in only one sample collected prior to
2020 (below the 2L standard at a concentration of 81 µg/l in the November 2018 sample from
Upper Aquifer well MW-3/CPW-15S). Non-compliance reports were submitted to DWR in
accordance with requirements of the SDIBR permit for the 2020 nickel detections in MW-
17/CPW-7S, and additional evaluation of nickel concentrations in CPW-7S will be completed
during 2021 (as approved by DWR).
Total chromium was detected above the 2L standard of 10 µg/l in samples collected from MW-
24/CPW-4D during 2020. Elevated chromium in MW-24/CPW-4D is attributable to the PPA of
the site and is already known to the NC Department of Environmental Quality (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.
Results of analysis of groundwater samples collected from SDIBR permit compliance
monitoring wells in the period between July 2018 and November 2020 are summarized in the
Summary of Affected Wells attached to this report and well locations are depicted in the attached
Facility Map.

15A NCAC 02L.0202 Ground Water Quality Standard
`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. CPW-13, CPW-75, and CPW-123 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 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
