Re: November 2022 Groundwater Monitoring Compliance Report Forms
Elementis Chromium Castle Hayne Manufacturing Facility
Occidental Chemical Corporation SDR Permit No. WQ0001492
Castle Hayne, North Carolina
H&H Job No. OXY-004
Dear Sir or Madam:
On behalf of Glenn Springs Holdings, Inc. (for Occidental Chemical Corporation), Hart &
Hickman, PC (H&H) is submitting the enclosed Groundwater Quality Monitoring: Compliance
Report Forms (GW-59A and GW-59) and laboratory analytical report for groundwater samples
collected during November 2022 in accordance with the Occidental Chemical Corporation Surface
Disposal of Residuals (SDR) Permit No. WQ0001492 for the Elementis Chromium Castle Hayne
Manufacturing Facility. Under the terms of the SDR 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) in groundwater 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 SDR 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.

The results of the November 2022 monitoring indicated COCs above 2L standards or background.
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 2022 analytical results
because these conditions are already known to DWR and are addressed under the 1-CAP.
Immediate notification of elevated chromium in well MW-24/CPW-4D was not made after receipt
of the November 2022 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 and nickel are not
COCs in the 1-CAP, if chromium and/or nickel concentrations are detected above the 2L standards
in the compliance wells (other than chromium in well MW-24/CPW-4D), notification is made to
DEQ in accordance with the SDR permit.
November pH Values
Based on initial review of the November 2022 and prior pH data, pH levels below the 2L standard
range were measured in significantly more wells during November 2022 than during previous SDR
permit compliance monitoring events, and the November 2022 average of measured pH levels for
the sampled wells (5.75 s.u.) was approximately 1.5 s.u. lower than the average of measured pH
levels for the wells during each compliance monitoring event completed in the period between
July 2020 and July 2022 (when averages for each event ranged from 7.05 to 7.86 s.u.). Equipment
used to measure pH in the field was properly calibrated by sampling personnel using multiple pH
standard solutions (pH 4.0, 7.0, and 10.0 s.u.) prior to the start of sampling on each day of the
event. Based on historical data, it appears that pH levels measured during the November 2022
event are artificially low. H&H discussed this issue with the vendor (Eastern Solutions, LLC of
Charlotte, NC) who supplied the rental equipment used by H&H sampling personnel to measure
pH in the field. Eastern Solutions indicated they had recently been notified by other customers of
similarly apparent low field -measured pH values, and that they completed in-house testing of
calibration solutions from multiple suppliers. Based on the testing performed by Eastern Solutions,
elevated pH levels (approximately 1 s.u. high) were measured in a batch of 4.0 s.u. calibration
solution which was distributed with rented water quality meters.
Based on the information presented above, the November 2022 pH data reported in the GW-59
forms and the attached table for each well were adjusted by adding 1.25 s.u. to the field -measured
pH value. This correction results in an average pH level of 7.00 s.u. for the wells during
November 2022, and is slightly lower than the lowest average of measured pH levels for the wells
during a compliance monitoring event completed in the period between July 2020 and July 2022
(7.05 s.u. during November 2021).
November 2022 Non -Compliance Summary
Results of analysis of the November 2022 SDR compliance monitoring event indicate total
chromium was detected above the 2L standard of 10 micrograms per liter (µg/1) in compliance
monitoring well MW-19/CPW-9S (31.7 µg/1). Total chromium is not a COC which is being
addressed by the 1-CAP (discussed above). In accordance with Condition IV.12 of the SDR permit,

non-compliance notification was made to the DWR Wilmington Regional Office via email and
telephone on December 8, 2022. (H&H received the analytical laboratory report after business
hours on December 7, 2022.) In addition, a non-compliance notification report was submitted to
the DWR Wilmington Regional Office on December 12, 2022.
As shown in Figure 1, MW-19/CPW-9S is located along the northwestern perimeter of Quarry
Section 1. 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-19/CPW-9S. Prior to November 2022, total chromium was
most recently detected above the 2L standard in MW-19/CPW-9S during November 2008 (12
µg/1). Based on the low frequency of total chromium detections above the 2L standard in samples
collected from well MW-19/CPW-9S 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 chromium above the 2L standard in MW-19/CPW-9S is an anomalous occurrence,
and a likely/potential source of the detection is not known. Therefore, the non-compliance report
submitted to DWR recommended no additional assessment of the anomalous detection prior to the
next SDR Permit -required sampling event in July 2023. Future detections (if any) of total
chromium in SDR Permit compliance samples collected from the well will be addressed in
accordance with Conditions I.1 and I.2 of the current SDR Permit.

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)
