Report of Rock Blasting 0 Cell No. 6B
Foothills Regional Landfill Caldwell County, North Carolina
September 2023 HHNT Project No. 6703-1142-01
1. PROJECT SUMMARY
Blasting activities were required as part of the ongoing construction of Cell No. 6B at the Foothills Regional
MSW Landfill, located on Cheraw Road in Caldwell County, North Carolina. This landfill is owned by
Caldwell County, and operated by Republic Services of North Carolina, LLC.
A formal Blasting Plan was prepared and submitted to NCDEQ for review and approval on May 1, 2023, in
support of this request. This plan was reviewed and approved by the Solid Waste Section in a letter dated
May 2, 2023.
At this time, all blasting activities have been completed and all blasted material has been removed. A
total of five (5) blasting events were performed between May 10, 2023, and May 19, 2023.
As required by the Section's approval letter, we are providing the Blasting Summary Report to document
the blasting activities that were performed in association with the blasting work. This report includes:
• Final volume of rock removed.
• Rock blasting observations including copies of all blasting reports and vibration monitoring data.
Note: The following information has been included in the "Geologic Observation Report: Cell No. 6B,"
prepared by Bunnell Lammons Engineering and dated September 11, 2023. This information has not been
duplicated in this Blasting Summary Report.
• Rock Blasting Plan (FID 1792134)
• Rock Blasting Plan Approval Letter (FID 1792135)
• Vertical Separation Demonstration
• Water Level Measurements
A copy of these reports will be included in the final CQA Report for the project.
Due to the wet weather over the last several months and the volume of blasted material required to be
moved, it has taken additional time for the general contractor to remove all the blasted material so that
final, top of rock survey shots could be obtained. We appreciate the Section's willingness to grant an
extension on this submittal.

2. ROCK BLASTING OBSERVATIONS
During the construction of Cell 613, a zone of rock located within the proposed cell was blasted, excavated
and removed so that the cell design grades could be achieved. The general area of rock blasting within
Cell No 6B is shown in the approved Blast Plan.
A blasting plan was prepared by Carolina Drilling, Inc (a subcontractor to Earnhardt Grading, Inc.) and
submitted by HHNT to the North Carolina Department of Environmental Quality (NCDEQ) on May 1, 2023.
The Blasting Plan was approved with conditions by the NCDEQ as specified in their letter dated May 2,
2023. Following NCDEQ's approval, the first blasting event was performed on May 10, 2023 after
providing the required notice to NCDEQ. In total, approximately 50,000 CY of rock material was blasted
and removed to achieve the required design grades.
A. Vibration Blast Monitoring
Five (5) rock blasting events were performed between May 10, 2023, and May 19, 2023, by
Carolina Drilling, Inc. Vibration monitoring was performed by Vibra-Tech, Inc. of Fort Mill, South
Carolina. The rock blasting reports are included in Appendix A. In addition, Daily Reports which
were prepared bythe on -site CQA Firm (Bunnell Lammons Engineering) have been enclosed which
document project activities each day, including blasting. These reports have been included in
Appendix B. The seismic analysis and monitoring data has been included in Appendix C and
includes information regarding the date, time, station identification and vibration monitoring
results from each seismograph utilized during the blasting activities. A total of three (3)
seismographs were used to monitor vibration for this project. These locations were selected and
used interchangeably as appropriate, which included:
• Location 1— Top of Berm
• Location 2 — Closest Monitoring Well (MW-11)
• Location 3 — Between the scale house storage trailer.
The specific limitation of peak particle velocity (PPV) in the approved blasting plan is 1.0 inch per
second (ips) to the nearest protected structure. In this case, Location 3 represents the
seismograph that was used to monitor PPV at the nearest structure. Each of the reported
vibration results were less than the 1.0 ips with a maximum of 0.771 ips (Location 1 on May 12,
2023).
B. Groundwater Level Measurements
Groundwater levels were measured in the closest groundwater monitoring well, as requested by
NCDEQ. A pre- and post -blast water level was taken from groundwater monitoring well MW-11.
The head difference in the pre -and post -blast water levels of the groundwater monitoring well
sampled showed no significant change in head.
A summary of the collected water levels is included in BLE's "Geologic Observation Report: Cell
No. 6B.

September 2023 1111iHNT Project No. 6703-1142-01
C. Vertical Separation Requirements
At the completion of blasting, after the general contractor (Earnhardt Grading) had removed the
blasted material, survey data were obtained by Earnhardt and submitted to HHNT for review and
confirmation of vertical separation. Using this survey data, HHNT prepared a surface so that the
entire area could be evaluated against the Cell 6B base grades.
Upon our review, almost all the areas evaluated met, and in many cases exceeded the minimum
4' of separation required by the NCDEQ Solid Waste Rules. There were a few isolated areas along
the edges of the blasted area that did not meet the required 4' separation requirement based on
the survey data.
In an effort to confirm separation, HHNT selected points within these areas, which were located
in the field so that the contractor could excavate down at those locations to see if the required
depth could be achieved. Additional rock was removed at these locations using a rock hammer
and the areas were re -surveyed. The survey data was reviewed by HHNT to confirm the required
separation from rock had been achieved.
A sketch was included in BLE's "Geologic Observation Report: Cell No. 613" which shows the top of
rock as -built data provided by the contractor and the separation that was achieved below the
design bottom of clay grades in Cell 6B. Based on our detailed review of the data, all areas meet
or exceed the required separation within the Cell 6B area.

This report summarizes the vibration activity detected by the continuous recording seismographs in
the near vicinity of the Foothills Landfill project in Lenoir, North Carolina, during the time period
May 10-19, 2023. The report compares the vibration levels detected by the continuous recording
seismographs to NFPA 495, Explosive Materials Code, which outlines vibration limits that are safe for
typical residential structures.
The maximum ground vibration of the recorded peak velocity for blasts during this time period
occurred on May 12, 2023, at 12:10 PM. The maximum was 0.771 inches per second (ips) with a
corresponding frequency of 45.5 hertz (Hz), which was below the established criteria for ground
vibration at blasting operations as recommended by the National Fire Protection Association (NFPA)
(NFPA 495 11.2.1: 2018 Edition).
The maximum value for the recorded air overpressure for blasts during this time period occurred on
May 10, 2023, at 2:30 PM. The maximum was 140 dBL (0.029 psi), which was 224% of the 133 dBL
criteria for air overpressure as recommended by the National Fire Protection Association (NFPA)
(NFPA 495 11.3: 2018 Edition).
The invoice for this service will follow under separate cover. Should you have any questions
concerning this report, please do not hesitate to contact our office.

Javy checked out the seismograph and solar panel that were hit by
something after the blast yesterday. It was not damaged.
The data from yesterday's blast is attached. The non -blast data
points from the strike after the blast have been removed, so the
maximum PPV of the blast is now apparent. It was 0.579 in/s.
Please let us know if you have any questions.
