Re: July 2020 Groundwater Monitoring Compliance Report Forms DWR SECTION
Elementis Chromium Castle Hayne Manufacturing Facility INFORMATION PROCESSING UNIT
Occidental Chemical Corporation SDIBR Permit No. WQ0001492
Castle Hayne, North Carolina
H&H Job No. OXY-004
Dear Sir or Madam:
In accordance with Sections IV.7 and IV.9 of Surface Disposal of Industrial Byproducts Residuals
(SDIBR) Permit No. WQ0001492, Hart & Hickman, PC (H&H), on behalf of Glenn Springs
Holdings, Inc./Occidental Chemical Corporation, is submitting the enclosed Groundwater Quality
Monitoring: Compliance Report Forms (GW-59A and GW-59) and laboratory analytical reports
for groundwater samples collected in accordance with the SDIBR permit during the month of
July 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) above standards by processes of natural attenuation pursuant to
15A NCAC 2L .0106(1). The COCs addressed by the 1-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 1-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 July 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 July 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.
July 2020 Non -Compliance Summary
Analytical results of the July 2020 SDIBR compliance monitoring event indicate total nickel was
detected above the 15A NCAC 02L .0202 groundwater standard (2L standard) of 100 micrograms
per liter (µg/1) in the sample collected from compliance monitoring well MW-17/CPW-7S. 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 and email on
August 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
August 7, 2020.
Well MW-17/CPW-7S is located along the eastern perimeter of Quarry Section I (Figure 1)
between the PPA of the site and the Quarry. Residual solids generated by the Elementis Chromium
Castle Hayne Manufacturing Facility's wastewater treatment plant (WWTP) are currently
disposed in Quarry Section 2, and therefore not in the area of well MW-17/CPW-7S. Total nickel
is not a COC which is being addressed by the 1-CAP (discussed above). Compliance monitoring
samples have been analyzed for total nickel during only those monitoring events completed after
issuance of the SDIBR permit (i.e., since November 2016), and total nickel was previously
detected in only one of the samples (below the 2L standard at a concentration of 81 µg/1 in the
November 2018 sample from Upper Aquifer well MW-3/CPW-15S). Because total nickel has not
been detected above the 2L standard in SDIBR permit compliance wells prior to July 2020 and
residual solids are not being disposed in the quarry section where nickel was detected above the
2L standard, the total nickel detection in MW-17/CPW-7S during July 2020 is an anomalous
occurrence. In the August 7, 2020 non-compliance notification report, we recommended that no
additional assessment or evaluation of the total nickel detection in MW-17/CPW-7S be completed
prior to November 2020 (when a compliance monitoring event will be completed in accordance
with the SDIBR permit). Dr. Morella Sanchez -King (DWR) concurred with this recommendation
during a phone call with H&H on August 27, 2020. During the November 2020 monitoring event,
each compliance monitoring well (including MW-17/CPW-7S) will be sampled for total nickel.
After receipt of the November 2020 analytical data, recommendations for additional sampling
and/or alternative actions will be proposed, if warranted based on the results of the sample
analyses.

Site -specific target cleanup concentrations for iron are included in the DWRappmved May 28, 1999 I -CAP for remediation of compounds of concern above standards by processes of natural
attenuation pursuant to 15A NCAC 2L 0106(1). The target cleanup concentrations for iron are background levels established under a now -expired Special Order by Consent (SOC) agreement.
The A. -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-15, CPW-75, 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.

Dear Ms.Finn,
Service Request No:R2006268
Enclosed are the results of the sample(s) submitted to our laboratory July 20, 2020
For your reference, these analyses have been assigned our service request number R2006268.
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.

Laboratory Results for: Castle Hayne 258-402-D02-3100
Dear Ms.Finn,
Service Request No:R200651O
Enclosed are the results of the sample(s) submitted to our laboratory July 24, 2020
For your reference, these analyses have been assigned our service request number R2006510.
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 (> ] 00% 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.
