Residuals were not deposited in Quarry 1 Section I (QS 1) during 2019. It is estimated that 87,135
dry tons of residuals were deposited in Quarry 1 Section II (QS2) during 2019. Collectively, QS 1
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 QS 1
is 3,747,306 cubic yards. The estimated remaining capacity of QS 1 is 430,411 cubic yards, which
equates to approximately 2.2 years at the maximum loading rate.
The total estimated weight of residuals deposited into QS2 during 2019 was 87,135 dry tons. As of
December 31, 2019, the estimated cumulative residual volume contained in QS2 was 2,825,687
cubic yards. The estimated remaining capacity on this date was approximately 516,130 cubic yards.
Based on these estimates, the estimated remaining useful life of QS2 is 2.8 years at the maximum
loading rate. 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.
Chromium ceiling concentrations presented in Condition II.8 of the permit were exceeded for the
entire reporting period; however, as noted in Condition II.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
chromium, iron, and TDS above North Carolina 21, standards, and pH outside of the 2L standard
range in groundwater samples collected during 2019 from one or more compliance monitoring wells
which are sampled in accordance with the SDIBR permit. With the exception of the total chromium
detections above the 2L standard, the 2019 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 2019 Annual Quarry Natural Attenuation Ground
Water Monitoring Report dated January 29, 2020 was submitted to DWR to document the methods
and results of groundwater monitoring completed during 2019 to satisfy CAP monitoring.
Total chromium was detected above the 2L standard of 10 micrograms per liter (µg/1) in samples
collected from MW-24/CPW-4D during 2019. Elevated chromium in MW-24/CPW-4D is
attributable to the Plant Process Area (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.
Total chromium was detected slightly above the 2L standard during November 2018 in three SDIBR
permit compliance monitoring wells (MW-1/CPW-135, MW-9/CPW-9D, and MW- I O/CPW- I OD)
located around the perimeter of the Quarry. Prior to November 2018, detections of total chromium
above the 2L standard in SDIBR permit compliance wells located along the perimeter of the Quarry
were rare. Additional evaluation of chromium concentrations in the three wells was completed
during December 2018 through May 2019. Non-compliance notifications for detections of total
chromium above the 2L standard during this period were provided to DWR in accordance with
Condition IV.12 of the SDIBR permit and non-compliance resampling reports were submitted to
DWR. For additional information, refer to the Non -Compliance Resampling Report — May 2019
dated May 28, 2019 which was submitted to DWR.
During the July 2019 SDIBR compliance sampling event, total chromium was detected above the
2L standard in three monitoring wells located along the perimeter of the Quarry (MW-2/CPW-14S,
MW-9/CPW-9D, and MW-15/CPW-15D). Additional evaluation of chromium concentrations in the
three wells was subsequently completed during August and September 2019. Results of analysis of
samples collected from the three wells on August 15, 2019 indicated total chromium was detected
slightly above the 2L standard in two of the three monitoring wells (MW-2/CPW-14S and MW-
9/CPW-9D) and that total chromium was not detected in monitoring well MW-15/CPW-15D.
Dissolved chromium was not detected in field -filtered samples collected from any of the three
monitoring wells on August 15, 2019. These three wells were resampled on September 2, 2019 to
further evaluate the total chromium concentrations detected in the wells. Results of analysis of the
September 2, 2019 samples indicated dissolved and total chromium were not detected in wells MW-
9/CPW-9D and MW-15/CPW-15D. Total chromium was detected above the 2L standard in the
September 2, 2019 unfiltered sample collected from MW-2/CPW-14S; however, dissolved
chromium was not detected in the field -filtered sample collected from the well. MW-2/CPW-14S
was resampled on September 16, 2019 to further evaluate the total chromium concentrations which
had recently been detected in the well. Results of analysis of the September 16, 2019 samples
indicated dissolved and total chromium were not detected in MW-2/CPW-145.

Based upon the results of the September 2019 samples, and as approved by DWR, no additional
sampling of the wells was completed prior to the November 2019 semi-annual SDIBR permit
compliance monitoring event. Non-compliance notifications for detections of total chromium above
the 2L standard during July through September 2019 were provided to DWR in accordance with
Condition IV.12 of the SDIBR permit and non-compliance resampling reports were submitted to
DWR. For additional information, refer to the Non -Compliance Resampling Report —
September 2019 dated September 27, 2019 which was submitted to DWR. During November 2019,
total chromium was not detected above the 2L standard in any of the wells included in the
SDIBR permit compliance monitoring event except PPA well MW-24/CPW-4D (discussed above).
As approved by DWR, no additional monitoring of SDIBR permit compliance monitoring wells will
be completed prior to the next semi-annual SDIBR permit compliance monitoring event which will
be completed in accordance with the SDIBR permit in July 2020.
Results of analysis of groundwater samples collected from SDIBR permit compliance monitoring
wells in the period between July 2017 and November 2019 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 Oualty 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(0. The target cleanup concentrations for iron are background levels established under a now.expued Special Order by Consent (SOC) agreement.
The site -specific target iron levels in the 4CAP are: 3.3 mgtL 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-1S. CML7S, 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-fi8ered sample; NE = not established
Bold concentration exceeds the groundwater standard (site -specific standard for bon)
Data for samples collected during the last three years included in table
Only those analyles detected above a groundwater standard (site -specific standard for iron) in at least one sample are Included in table
