Dear Ms. Graham:

Terracon.com
Terracon Consultants, Inc. (Terracon) has prepared this Soil Export Request to obtain North
Carolina Department of Environmental Quality (NCDEQ) approval to export foundation spoils
and pile cap grading fill to the Meridian Waste Shotwell Construction & Demolition (C&D)
Landfill. This material will be used beneficially as working cover at the landfill. In support of
this request, presented below is analytical data collected from test auger cast piles and soil
borings across the Raleigh Union Station (RUS) Bus site in order to characterize the spoils
generated during the installation of cast auger piles and pile caps.
The auger cast piles are constructed using augers ranging from 24 to 36-inches in diameter
to advance borings to a depth at which suitable rock is encountered. Previous geotechnical
studies conducted by the deep pile contractor at the site determined that the depth of piles
will range from 50-feet below ground surface (bgs) to up to 80-feet bgs. The building
foundation calls for approximately 200 piles across the footprint of the building. As the augers
are advanced, soil cuttings (i.e., spoils) will be raised to the land surface, and will need to be
removed from the site.
Approximately 12,000 cubic yards (CY) of soil is planned to be exported from the site starting
in November 2023 through January/February 2024. Approximately 4,000 CY of spoils are
anticipated from auger cast piles with the remainder (approximately 8,000 CY) of material
coming from shallow locations across the site during pile cap construction. The shallow
material that will be removed for construction will be a portion of the beneficial reuse fill
imported to the site from Lake Wheeler Assemblage Brownfields site and clean fill imported

from Wake Stone Knightdale used to fill basement voids and level the site. Location maps are
included as an Exhibit to this letter request.
Soil export is proposed to be exported to the Meridian Waste Shotwell C&D landfill
(https://www.meridianwaste.com/nc/wendell/meridian-waste-shotwell-environmental-
ark ). Analytical data was provided to the site manager at Meridian Waste for approval to
export soil. Written approval for soil export to the Meridian Waste Shotwell Environmental
Park is included as an Exhibit to this letter request.
Scope of Work & Sampling Methodology
Terracon collected samples from four soil borings (October 2023) and five soil stockpiles
(November 2023) associated with test auger cast piles.
On October 12, 2023, four soil borings were advanced via direct push technology (DPT) in
approximate locations of proposed auger cast piles. Soils were collected using 2-inch Macro -
Cores° in 5-foot sections. A grab soil sample was collected for analysis of volatile organic
compounds (VOCs) and a three-part composite was collected for analysis of semi -volatile
organic compounds (SVOCs), Resource Conservation and Recovery Act (RCRA) metals, and
hexavalent chromium. A duplicate soil sample was also collected from a randomly selected
boring. Depth of DPT soil borings ranged from 20 to 25-feet bgs. Terracon collected samples
from each soil boring (SB-01 through S13-04) in laboratory supplied glassware and submitted
them to Eurofins analytical laboratory in Savanah, Georgia. Samples were packed in ice and
shipped overnight via FedEx under chain -of -custody procedures.
In order to collect samples from depths beyond the DPT drill rig capability, Terracon returned
to the site on November 20 and 21, 2023 to collect soil samples from the auger cutting
stockpiles during test cast auger piles. The deep pile contractor advanced five deep borings
with a crane -mounted 24-inch auger. Spoils from the test cast auger piles were generated in
close proximity to each boring location, and samples were collected directly from the spoils.
The test cast auger piles ranged in depth from approximately 35-feet to 90-feet bgs.
Composite samples were collected from cuttings from three separate aliquots during boring
advancement, and composited onsite, for analysis of SVOCs and RCRA metals. A grab sample
was collected from the spoils for analysis of VOCs. The sample with the highest total chromium
concentration was selected for analysis of hexavalent chromium. A duplicate sample was
collected from a randomly selected boring. Samples were collected in laboratory supplied
glassware and submitted to Eurofins analytical laboratory in Savanah, Georgia. Samples were
packed in ice and shipped overnight via FedEx under chain -of -custody procedures.
A map of soil boring locations, field notes and photos, and soil boring logs are included as an
Exhibit to this letter request.
Laboratory Analysis
For both the October and November 2023 sampling events, analytical results from the
laboratory report were tabulated by Terracon and compared to the NCDEQ residential, non -

residential, and protection of groundwater preliminary soil remediation goals (PSRGs). The
methods of analysis were as follows:
■ VOCs via United States Environmental Protection Agency (USEPA) method 8260D,
■ SVOCs via USEPA method 8270E,
■ Hexavalent Chromium via USEPA method 7199, and
■ RCRA 8 Metals via USEPA 6010D.
Sampling Results
Sample results did not exceed non-residential or protection of groundwater PSRGs. The
residential PSRG was exceeded for hexavalent chromium (Cr VI) in SB-03 at 1.56 J mg/Kg
and arsenic in SB-01 at 1.26 J mg/Kg. Other analytes were detected above their laboratory
detection limits, but below their respective PSRG including metals and polynuclear aromatic
hydrocarbons (PAHs). A summary of analytical results is included in the appendix to this letter
request. A summary table of chemical constituents detected in soil from the fill donor site
(Brownfields ID #25075-21-092 — Lake Wheeler Assemblage) is also included.
QA/QC
The laboratory analytical reports contain additional information regarding the sample
preparation, analysis, and results that should be considered in the interpretation of the data.
Quality assurance/quality control (QA/QC) of laboratory analytical data was maintained using
the following methods and procedures:
■ Established reporting limits (RLs) with the laboratory that meet project Data Quality
Objectives (DQOs);
■ Laboratory QA/QC controls, such as laboratory control standard (LCS), matrix spike
(MS), and matrix spike duplicate (MSD);
■ Collection of samples in laboratory provided containers;
■ Chain -of -custody protocols; and
■ Storage and transportation of samples in temperature -controlled containers.
One duplicate was collected per sampling event. Duplicate soil sample ("DUP") was collected
from SB-01 on October 12th. Duplicate soil sample ("DUP_20231121") was collected from B1
on November 215t. One temperature blank was included with each cooler shipped to the
laboratory.
Constituent concentrations qualified with ]-flag (J), if present, indicated the constituent was
detected at a concentration above the laboratory sample detection limit (SDL), but below the
laboratory method quantitation limit (MQL). Constituent concentrations qualified with a J-flag
were considered estimated values. Additionally, the laboratory conducts QC of the data sets
to ensure data meets data quality objectives. Terracon reviewed the laboratory reports and
did not identify any QC standards substantially out of the control limits and/or that would
negatively impact the data.

DESIGN DEVELOPMENT NOTES
1. TEMPORARY BRACING OF THE EXISTING BRICK FACADE TO BE PROVIDED BY THE CONTRACTOR. ONCE PILE CAPS ARE
INSTALLED, TEMPORARY BRACING SHALL BE ADJUSTED TO BE WITHIN BUILDING FOOTPRINT AND TO BE SUPPORTED
OFF OF NEW COLUMN PILE CAPS UNTIL PERMANENT STRUCTURE IS CONSTRUCTED.
2. DUE TO PHASED CONSTRUCTION OF PARKING GARAGE ABOVE, LEVEL 2 PT TRANSFER GIRDERS AT TRANSIT HAVE BEEN
DESIGNED TO AVOID STAGE STRESSING
3. COLUMN SIZES WITHIN RESIDENTIAL TOWER HAVE BEEN DESIGNED AS ONE SIZE AS REQUESTED BY THE GENERAL
CONTRACTOR. COLUMN SIZE REDUCTIONS MAY BE STUDIED UPON OWNER REQUEST IN THE TOWER.
4. CYCLICAL SEASONAL TEMPERATURE CHANGES WILL IMPACT THE UNCONDITIONED GARAGE STRUCTURAL FRAME.
INCREASED STRESS IN THE STRUCTURE DUE TO EXPANSION AND CONTRACTION MAY CAUSE INCREASED AMOUNTS
OF CRACKING IN THE SLABS. THIS WILL REQUIRE LONG-TERM MAINTENANCE OF REPAIRING CRACKS TO ENSURE THE
SLABS ARE PROTECTED FROM CORROSION.
5. POUR STRIPS WITHIN THE ELEVATED FLOORS TO RMAIN OPEN FOR 28 DAYS. THE POUR STRIP UTILIZES SELF
SUPPORTING CANTILEVERED SLABS TO ELIMINATE SHORING OF THE POUR STRIP WITHIN THOSE BAYS.
6. GC TO COORDINATE UNDERGROUND UTILITIES TO AVOID UNDERGROUND PILES, PILE CAPS, FOUNDATIONS, AND BELOW
