Residuals were not deposited in Quarry 1 Section I (QS1) during 2021. It is estimated that
84,344 dry tons of residuals were deposited in Quarry 1 Section II (QS2) during 2021.
Collectively, QS1 and QS2 are permitted for a maximum of 171,000 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 QS I 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 2021 was 84,344 dry tons. As
of December 31, 2021, the estimated cumulative residual volume contained in QS2 was
3,059,098 cubic yards. The estimated remaining capacity on this date was approximately
608,444 cubic yards. Based on these estimates, the estimated remaining useful life of QS2 is 3.4
years at the maximum loading rate.
While chromium ceiling concentrations presented in Condition 11.6 of the permit were exceeded
for the entire reporting period, residuals were determined to be non-hazardous. As noted in
Condition 11.6, "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
deposited during the reporting period were determined to be non-hazardous under RCRA as
stipulated in permit Conditions IV.2 and IV.4. A residuals sample collected on September 15,
2021 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 IV.4. TCLP sample
analytical reports are attached to this report.

Non-Compliance Summary
Under the terms of the SDR peiuiit, 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 SDR permit.
On the attached Form DMSDF, the facility is noted as being out of compliance due to detections
of total chromium, total iron, total nickel, and TDS above North Carolina 2L standards, and pH
outside of the 2L standard range in groundwater samples collected during 2021 from one or more
of the SDR permit compliance monitoring wells. With the exception of detections of total
chromium and total nickel above 2L standards, the 2021 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 (DEQ) on July 28, 1999. The 2021 Annual
Quarry Natural Attenuation Ground Water Monitoring Report dated February 8, 2022 was
submitted to DWR to satisfy CAP monitoring reporting requirements.
Total chromium was detected at a concentration of 26 micrograms per liter (µg/l) (above the
2L standard of 10 µg/l) in Upper Aquifer well MW-18/CPW-8S during July 2021. MW-
I8/CPW-8S is located along the northwestern perimeter of Quarry Section 1 (which is not
currently used for residual solids disposal). Prior to July 2021, total chromium had only been
detected above the 2L standard in one sample collected from the MW-18/CPW-8S (13 µg/1
during November 2002). A non-compliance report was submitted to DWR in accordance with
requirements of the SDR penitit for the July 2021 chromium detection above the 2L standard in
MW-18/CPW-8S, and the well was resampled during August 2021. Results of analysis of the
August 2021 sample (which was split between two Iabs) indicated chromium was not detected in
MW-18/CPW-8S. In addition, chromium was not detected in MW-18/CPW-8S during the
November 2021 SDR permit compliance monitoring event. Based upon this information, the
July 2021 total chromium detection above the 2L standard in MW-18/CPW-8S is an anomalous
occurrence. Total chromium was also detected above the 2L standard of 10 µg/l in samples
collected from MW-24/CPW-4D during 2021; however, elevated chromium in MW-24/CPW-4D
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. Total chromium was not detected above the 2L standard in any other SDR
permit compliance wells during 2021.
Total nickel was detected above the 2L standard of 100 1.1g/1 in Upper Aquifer well MW-
17/CPW-7S during 2020 and 2021. Total nickel was detected in the July and November 2020
samples collected from CPW-7S at 228 and 723 µg/l,respectively, and in the July and
November 2021 samples collected from the well at 228 and 125 µg/l, respectively. In addition,

samples were collected from MW-17/CPW-7S to further evaluate total nickel concentrations in
the well during March, May, and September 2021, and total nickel was detected at
concentrations of 333, 306, and 136 .ig/1, respectively in the samples. The data indicate total
nickel concentrations in MW-17/CPW-7S have consistently been decreasing since
November 2020. MW-17/CPW-7S is located along the eastern perimeter of Quarry Section 1
between the PPA of the site and the Quarry and, as noted previously, Quarry Section 1 is not
being used for residuals disposal. Non-compliance reports were submitted to DWR in
accordance with requirements of the SDR permit for the 2020 and 2021 nickel detections above
the 2L standard in MW-17/CPW-7S. Additional evaluation of nickel concentrations in MW-
17/CPW-7S will be completed as part of the SDR permit compliance monitoring during 2022
and future detections (if any) of total nickel and/or chromium in SDR permit compliance wells
will be addressed in accordance with Conditions I.1 and 1.2 of the SDR permit (which include
provisions for possible submittal of a Comprehensive Site Assessment and amendment of the
CAP if certain criteria are met).
•
Results of analysis of groundwater samples collected from SDR permit compliance monitoring
wells in the period between July 2019 and November 2021 are summarized in the Summary of
Affected Wells attached to this report and well locations are depicted in the attached Facility
Map.

COMMENTS:
DOC. QA.002 Rev 1

If residuals generated by a particular residuals source-generating facility are insufficient to require a
surface disposal events during a required sampling period as specified in the most recently-certified
Attachment A of this permit (e.g. no surface disposal occur during an entire year when annual
monitoring is required), no sampling data is required during the period of inactivity. The Permittee
shall submit an annual report, as required in condition IV. 9., even in the event that no surface
disposal events occur during an entire year; the annual report shall include an explanation for
missing sampling data.
Only residuals that are generated by the residuals source-generating facilities that are identified as
being exempt from this condition in the most recently-certified Attachment A of this permit shall not
be required to comply with this monitoring requirement.
The TCLP analysis shall include the following parameters (i.e., note the regulatory level in
milligrams per liter in parentheses):
Arsenic(5.0) 1,4-Dichlorobenzene(7.5) Nitrobenzene(2.0)
Barium(100.0) 1,2-Dichloroethane (0.5) Pentachlorophenol (100.0)
Benzene(0.5) 1,1-Dichloroethylene(0.7) Pyridine(5.0)
Cadmium(1.0) 2,4-Dinitrotoluene(0.13) Selenium(1.0)
Carbon tetrachloride(0.5) Endrin(0.02) Silver(5.0)
Chlordane(0.03) Hexachlorobenzene (0.13) Tetrachloroethylene(0.7)
Chlorobenzene(100.0) Heptachlor(and its hydroxide) (0.008) Toxaphene(0.5)
Chloroform(6.0) Hexachloro-1,3-butadiene(0.5) Trichloroethylene(0.5)
Chromium(5.0) Hexachloroethane(3.0) 2,4,5-Trichlorophenol(400.0)
m-Cresol(200.0) Lead(5.0) 2,4,6-Trichlomphenol (2.0)
o-Cresol (200.0) Lindane(0.4) 2,4,5-TP (Silvex) (1.0)
- p-Cresol (200.0) Mercury(0.2) Vinyl chloride(0.2)
Cresol (200.0) Metboxychlor(10.0)
2,4-D (10.0) Methyl ethyl ketone (200.0)
3. Residuals generated by the approved residuals source-generating facility listed in Condition I. 4.
shall be analyzed to demonstrate that they are non-ha7Ardous under RCRA with respect to chromium
leachability(i.e.,leachate from a TCLP analyzed for chromium only).
The following sampling schedule shall be followed:
a.Grab sample: One per month, minimum.
b.Composite sample: One per month, minimum.
The results of all analytical determinations shall be maintained on file by the Permittee for a
minimum of five years and shall be submitted on a yearly basis to the following address:

Notes
1 15A NCAC 02L.0202 Ground Water Quality Standard
2 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(1). 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 1-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 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
*split sample analyzed by Pace Analytical Services(all other samples analyzed by ALS Environmental)
