Re: November 2020 Groundwater Monitoring Compliance Report Formms vp
Elementis Chromium Castle Hayne Manufacturing Facility ?a
Occidental Chemical Corporation SDIBR Permit No. WQ0001492 ?�
Castle Hayne, North Carolina
H&H Job No. OXY-004
Dear Sir or Madam:
N
In accordance with Sections IV.7 and IV.9 of Surface Disposal of Industrial Byproducts Resitls
(SDIBR) Permit No. WQ0001492, Hart & Hickman, PC (H&H), on behalf of Glenn S * gs
Holdings, Inc./Occidental Chemical Corporation, is submitting the enclosed Groundwater ua ity�
Monitoring: Compliance Report Forms (GW-59A and GW-59) and laboratory analytical reportsQ
for groundwater samples collected in accordance with the SDIBR permit during the month of
November 2020. Under the terms of the SDIBR 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).
Background Information
The facility is currently operating under a 1999 Corrective Action Plan (I -CAP) for remediation of
compounds of concern (COCs) I groundwater above standards by processes of natural attenuation
pursuant to 15A NCAC 2L .0106(1). The COCs addressed by the I -CAP include chlorides, iron,
pH, and TDS. The objective of the 1-CAP is to reduce COC concentrations which exceed
groundwater standards at or outside of the compliance boundary established in the SDIBR permit
by natural attenuation. The target cleanup concentrations for the COCs except total iron are the
2L standards. 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 I -CAP monitoring reporting
requirements.

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 November 2020 analytical results
because these conditions are already known to DWR and are addressed under the 1-CAP.
Immediate notification of elevated chromium in MW-24/CPW-4D was not made after receipt of
the November 2020 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 is not a COC in the 1-
CAP, if chromium concentrations are detected above the 2L standard in the compliance wells
(other than MW-24/CPW-4D), the detections are reported to DEQ in accordance with the SDIBR
permit.
November 2020 Non -Compliance Summary
Analytical results of the November 2020 SDIBR compliance monitoring event indicate total nickel
was detected above the 2L standard of 100 micrograms per liter (µg/1) in the sample collected from
compliance monitoring well MW-17/CPW-7S (723 µg/1). Total nickel is not a COC which is
being addressed by the 1-CAP (discussed above). In accordance with Condition IV.12 of the
SDIBR permit, non-compliance notification was made to the Division of Water Resources (DWR)
Wilmington Regional Office via telephone on December 4, 2020, less than 24 hours after receipt
of the analytical data. In addition, a non-compliance notification report was submitted to the DWR
Wilmington Regional Office on December 7, 2020.
Total nickel was also detected above the 2L standard in MW-17/CPW-7S (228 µg/1) during the
July 2020 SDIBR permit -required groundwater monitoring. Non-compliance notification for the
July 2020 detection was made to the DWR Wilmington Regional Office via telephone and email
on August 4, 2020, and a non-compliance notification report for the July 2020 detection was
submitted to the DWR Wilmington Regional Office on August 7, 2020.
Well MW-17/CPW-7S is located within the review boundary along the eastern perimeter of Quarry
Section 1 between the PPA of the site and the Quarry (Figure 1). Residual solids generated by the
Elementis Chromium Castle Hayne Manufacturing Facility's wastewater treatment plant (W WTP)
are currently disposed in Quarry Section 2, and therefore not in the area of well MW-17/CPW-7S.
Compliance monitoring samples have been analyzed for total nickel during only those compliance
monitoring events completed after issuance of the SDIBR permit (i.e., since November 2016).
With the exception of the total nickel detections in MW-17/CPW-7S during July and
November 2020, total nickel has been detected in only one other compliance sample (below the
2L standard at a concentration of 81 µg/1 in the November 2018 sample from Upper Aquifer well
MW-3/CPW-15S).
A potential source of the nickel detections in MW-17/CPW-7S is not known at this time. Residual
solids are not actively disposed in Quarry Section 1 which is located immediately west of MW-
17/CPW-7S between the well and Quarry Section 2 (where residual solids are actively disposed).
In addition, nickel is not a COC in PPA groundwater. MW-17/CPW-7S is located approximately

1,500 ft upgradient of the Northeast Cape Fear River and nickel is not expected to migrate a
significant distance in the aquifer. As previously mentioned, total nickel has not been detected
above the 2L standard in SDIBR permit compliance wells prior to July 2020. Based on this
information, the nickel concentrations detected in MW-17/CPW-7S appear limited in extent and
of low risk to potential receptors. We believe that further evaluation of nickel concentrations in
the well is warranted prior to considering additional assessment or remediation activities.
Therefore, in the December 7, 2020 non-compliance monitoring report, we recommended that a
sample be collected from MW-17/CPW-7S for analysis of total nickel during March 2021 (i.e.,
prior to the next SDIBR permit -required sampling event in July 2021). After receipt of the
March 2021 nickel data, recommendations for additional sampling and/or alternative actions will
be proposed, if warranted based on the results of the sample analyses. Dr. Morella Sanchez -King
(DWR) concurred with this recommendation in an email dated December 11, 2020.

Dear Ms.Finn,
Service Request No:R2010835
Enclosed are the results of the sample(s) submitted to our laboratory November 14, 2020
For your reference, these analyses have been assigned our service request number R201O835.
All testing was performed according to our laboratory's quality assurance program and met the
requirements of the TNI standards except as noted in the case narrative report. Any testing not
included in the lab's accreditation is identified on a Non -Certified Analytes report. All results are
intended to be considered in their entirety. ALS Environmental is not responsible for use of less than
the complete report. Results apply only to the individual samples submitted to the lab for analysis, as
listed in the report. The measurement uncertainty of the results included in this report is within that
expected when using the prescribed method(s), and represented by Laboratory Control Sample
control limits. Any events, such as QC failures or Holding Time exceedances, which may add to the
uncertainty are explained in the report narrative or are flagged with qualifiers. The flags are explained
in the Report Qualifiers and Definitions page of this report.
Please contact me if you have any questions. My extension is 7471. You may also contact me via
email at [e-mail].

REPORT QUALIFIERS AND DEFINITIONS
U Analyte was analyzed for but not detected.
The sample quantitation limit has been
corrected for dilution and for percent
moisture, unless otherwise noted in the case
narrative.
Estimated value due to either being a
Tentatively Identified Compound (TIC) or
that the concentration is between the MRL
and the MDL. Concentrations are not verified
within the linear range of the calibration. For
DoD: concentration >40% difference between
two GC columns (pesticides/Arclors).
B Analyte was also detected in the associated
method blank at a concentration that may
have contributed to the sample result.
E Inorganics- Concentration is estimated due to
the serial dilution was outside control limits.
E Organics- Concentration has exceeded the
calibration range for that specific analysis.
D Concentration is a result of a dilution,
typically a secondary analysis of the sample
due to exceeding the calibration range or that
a surrogate has been diluted out of the sample
and cannot be assessed.
* Indicates that a quality control parameter has
exceeded laboratory limits. Under the
"Notes" column of the Form I, this qualifier
denotes analysis was performed out of
Holding Time.
+ Correlation coefficient for MSA is <0.995.
N Inorganics- Matrix spike recovery was outside
laboratory limits.
N Organics- Presumptive evidence of a compound
(reported as a TIC) based on the MS library search.
S Concentration has been determined using Method
of Standard Additions (MSA).
W Post -Digestion Spike recovery is outside control
limits and the sample absorbance is <50% of the
spike absorbance.
P Concentration >40% difference between the two
GC columns.
C Confirmed by GC/MS
Q DoD reports: indicates a pesticide/Aroclor is not
confirmed (>100% Difference between two GC
columns).
X See Case Narrative for discussion.
MRL Method Reporting Limit. Also known as:
LOQ Limit of Quantitation (LOQ)
The lowest concentration at which the method
analyte may be reliably quantified under the
method conditions.
MDL Method Detection Limit. A statistical value
derived from a study designed to provide the lowest
concentration that will be detected 99% of the
time. Values between the MDL and MRL are
estimated (see J qualifier).
H Analysis was performed out of hold time for LOD Limit of Detection. A value at or above the MDL
tests that have an "immediate" hold time which has been verified to be detectable.
