Subject: Report of Geologic Observation
Phase 3 - Cell 2K
Charlotte Motor Speedway Landfill-V (MSWLF)
Permit No. 13-04
Cabarrus County, North Carolina
Dear Ms. Drummond:
SCS Engineers, PC (SCS), on behalf of Atlantic Coast Consulting, Inc. and BFI Waste Systems of North
Carolina (a division of Republic Services), hereby submits this Report of Geologic Observation for Cell
2K at the Charlotte Motor Speedway (CMS) Landfill. Cell 2K is a 15.46-acre cell located south of Cell
2J. At this time, all 15.46 acres have been excavated to base grades and are ready for the
placement of clay liner.
The following document, prepared by David Garrett and Associates, of Raleigh, NC, and dated May
2009, was reviewed by SCS: Design Hydrogeologic Report, CMS Landfill V - Phase 3. This
document contains information on the geology and hydrogeology of the facility and expansion.
GEOLOGIC OBSERVATION
The following is a summary of the geologic field observations performed by Mr. Jared Hamela P.G., a
licensed NC geologist, on March 6, 2020 and April 6, 2020, in accordance with the Landfill's Permit
to Construct, No. 13-04-MSWLF-1992, Amendment 8, Attachment 2, Part I, Condition 11 and North
Carolina Solid Waste Regulations, 15A NCAC 1313.1624(b)(7)(B)(ii):
• Contractor excavation has revealed no rock formations within Cell 2K.
• No blasting was required in this area.
• Remnant cobbles and boulders of gabbro (originating from diabase features) and syenite,
varying in size from a few inches in length to up to 5 feet in length, were visible but not
present in any quantities that could be mapped.
• Material observed included tan, red -brown, sandy silts with partially weathered rock
fragments and clays (ML), residuum and saprolite from gabbro and syenite parent material
consistent with the Concord Pluton of the Charlotte Belt
• No perched groundwater was encountered in Cell 2K. No evidence of a spring, seep, or
other artesian conditions were observed.
The geology of the area of the cell inspected appears to be consistent with the observations and
geologic evaluations documented in the design Hydrogeologic report cited above. No geologic

features (i.e. pinnacles or tors) jutting above the existing grade established by the contractor were
observed. As such, the exposed conditions appear consistent with the expectations determined in
the permitting documents and conditions reported in previous cells. It is SCS's recommendation that
no modifications be made to the Ground Water Monitoring Plan or base grades. It is SCS's opinion
that no geologic features are present in Cell 2K that would bear impact on the construction or
operation of the Facility and no further geologic evaluations of Cell 2K are warranted.
This report will be presented as a component of the Construction Quality Assurance (CQA) report for
the cell. If you have questions, please do not hesitate to contact either of the undersigned at (704)
504-3107.
Sincerely,.
