Subject: Managed Reuse Work Plan for Sampling of Foundation Elements
Site: Former Domestic Laundry Brownfields Property - Vicinity of South
McDowell Street at Baxter Street
Charlotte, Mecklenburg County, North Carolina
NCBP Project # 25032-21-060
Dear Mr. Doorn:
On behalf of the Prospective Developer (PD), The Charlotte-Mecklenburg Hospital Authority,
Geosyntec Consultants of NC, P.C. (Geosyntec) has prepared this Managed Reuse Work Plan
for Sampling of Foundation Elements (Work Plan-MR) that provides procedures for the
sampling of existing concrete foundation elements (herein referred to as “material”) located on
the Former Domestic Laundry Brownfields Property in Charlotte, North Carolina (herein
referred to as the “Site”). The portion of the Site included in this Work Plan-MR includes 801
South McDowell Street, 801 Baxter Street, 900 Baxter Street, 928 Baxter Street, and 943 Baxter
Street which are represented by Mecklenburg County Parcel IDs 12520155, 12517303,
12520150, 12520158, and 12520154, respectively (“Subject Property”).
The objective of the sampling is to characterize the material to support potential reuse during
planned Site construction activities and development of disposal options. The data collected
from implementation of this Work Plan-MR will be used to prepare a Managed Reuse Plan for
North Carolina Brownfields Program (NCBP) review and approval.
The Former Domestic Laundry was located partially on a portion of the Site addressed as 801
South McDowell Street from approximately 1929 through 1967. A release from this former
facility is currently being managed under the North Carolina Department of Environmental
Quality (NCDEQ), Division of Waste Management, Dry-Cleaning Solvent Cleanup Act
(DSCA) Program under DSCA ID DC 60 0012. Chlorinated solvents and residual petroleum-
related compounds are present in soil, groundwater, and/or soil vapor onsite from former dry-
cleaning facility and other former property uses.
Although redevelopment plans are still underway, the PD currently has plans to redevelop the
Site as an educational tower and research/education facility and a parking garage (as part of the
Mr. Peter Doorn
21 July 2022
GC7466/CAR220110
planned future Wake Forest University medical school campus), multi-family residential
apartment building, hotel, commercial office space, and parking garage. The project is
collectively referred to by the PD as “Project Lookout”.
On 22 April 2021, the PD submitted a Brownfields Property Application (BPA) to the NCBP
for a portion of the Site including 801 South McDowell Street; 900, 928, and 943 Baxter Street;
and 1001, 1017, 1043, and 1051 East Morehead Street. A Letter of Eligibility (LOE) was
received on 18 October 2021 for the first BPA and the Site was assigned Brownfields Project
Number 25032-21-060. On 28 April 2022 a second BPA was submitted, requesting expansion
of the Brownfields Property to include 801, 821, 831, and 841 Baxter Street (hereafter referred
to as 801 Baxter Street) as well as 810 Baxter Street; 1110, 1106, and 1100 Harding Place; and
1105 Greenwood Cliff. On 4 May 2022, NCDEQ agreed via email to add 801 Baxter Street and
810 Baxter Street to the Brownfields Property and proposed other addresses be assigned a new
Brownfields Project Number. On 20 May 2022, an Environmental Management Plan (EMP)
for Early Grading and Demolition (EMP-1) was submitted to NCDEQ and is under review.
As previously described, data from the implementation of this plan will be used to prepare and
submit to the NCDEQ a Managed Reuse Plan using North Carolina General Statute (NCGS)
130A-294(m)1 and 130A.301.32 as a guide. The Managed Reuse Plan will be attached as an
addendum to EMP-1. The Managed Reuse Plan will be used to support the reuse of crushed on-
grade concrete building slab and foundations for construction logistical items such as temporary
lay-down area stone and temporary roads, and as permanent fill beneath impervious surfaces of
the proposed redevelopment. Off-site disposal of managed material at a permitted facility will
also be considered in the Managed Reuse Plan.
We respectfully request NCDEQ approval of this Work Plan-MR. Please do not hesitate to
contact us should you have questions or comments.
Sincerely,

1. INTRODUCTION
Geosyntec Consultants of NC, P.C. (Geosyntec) has prepared this Managed Reuse Work Plan for
Sampling of Foundation Elements (Work Plan-MR) that provides procedures for the sampling of
concrete foundation elements (herein referred to as “material”) for Kimley-Horn and Associates,
Inc. (KHA) on behalf of their end-client, The Charlotte-Mecklenburg Hospital Authority
(“Prospective Developer” or “PD”) for the Former Domestic Laundry Brownfields Property
(“Site” or “Subject Property”). The portion of the Site included in this Work Plan-MR includes
properties addressed as 801 South McDowell Street, 801 Baxter Street, 900 Baxter Street, 928
Baxter Street, and 943 Baxter Street in Mecklenburg County, Charlotte, North Carolina (herein
referred to as the “Subject Properties”), which are represented by Mecklenburg County Parcel IDs
12520155, 12517303, 12520150, 12520158, and 12520154. The location of these properties with
respect to the Site boundary are depicted on Figure 1.
Although redevelopment plans are still underway, the PD has plans to redevelop the Site as an
educational tower and research/education facility and a parking garage (as part of the planned
future Wake Forest University medical school campus), multi-family residential apartment
building and hotel, commercial office space, and parking garage. The project is collectively
referred to by the PD as “Project Lookout”. Project redevelopment plans are depicted on Figure
2.
The objective of the sampling is to characterize the material to support potential reuse during
planned Site construction activities and development of disposal options. The data collected from
implementation of this Work Plan-MR will be used to prepare a Managed Reuse Plan for North
Carolina Brownfields Program (NCBP) review and approval.
1.1 Environmental History
The Former Domestic Laundry was located partially on a portion of the Site addressed as 801
South McDowell Street from approximately 1929 through 1967. A release from this former facility
is currently being managed under the North Carolina Department of Environmental Quality
(NCDEQ), Division of Waste Management, Dry-Cleaning Solvent Cleanup Act (DSCA) Program
under DSCA ID DC 60 0012. Chlorinated solvents and residual petroleum-related compounds are
present in soil, groundwater, and/or soil vapor onsite from former dry-cleaning facility and other
former property uses, as depicted on Figure 3.
Outside of known subsurface impacts depicted on Figure 3, no known sources of release are
known to exist on the Site. Petroleum products are, however, currently stored/used on existing
GC7466/CAR220110 2 07/2022
concrete slabs on the Site. As depicted on Figure 3, there are two backup generators with 5,000-
gallon diesel aboveground storage tanks (ASTs) and hydraulic elevator equipment on 801 South
McDowell Street, and a backup generator with a 500-gallon diesel AST on 928 Baxter Street.
On 22 April 2021, the PD submitted a Brownfields Property Application (BPA) to the North
Carolina Department of Environmental Quality (NCDEQ) NCBP for a portion of the Site including
801 South McDowell Street; 900, 928, and 943 Baxter Street; and 1001, 1017, 1043, and 1051
East Morehead Street. A Letter of Eligibility (LOE) was received on 18 October 2021 for the first
BPA and the Site was assigned Brownfields Project Number 25032-21-060. On 28 April 2022 a
second BPA was submitted, requesting expansion of the Brownfields Property to include 801, 821,
831, and 841 Baxter Street (hereafter referred to as 801 Baxter Street) as well as 810 Baxter Street;
1110, 1106, and 1100 Harding Place; and 1105 Greenwood Cliff. On 4 May 2022, NCDEQ agreed
via email to add 801 Baxter Street and 810 Baxter Street to the Brownfields Property and proposed
other addresses be assigned a new Brownfields Project Number. On 20 May 2022, an
Environmental Management Plan (EMP) for Early Grading and Demolition (EMP-1) was
submitted to NCDEQ and is under review.
1.2 Current Site Use
The Subject Properties are currently developed primarily as commercial office space (Figure 1).
801 Baxter Street currently consists of four buildings with leased office space. 900 Baxter Street
currently consists of vacant commercial office space and 928 Baxter Street currently consists of
an office with medical services. 801 South McDowell Street contains an office building, that is
currently used for Atrium Health employee offices, information technologies (IT) services, and as
a data center. 943 Baxter Street currently consists of a parking lot for the Atrium Health facility.
1.3 Proposed Site Demolition and Managed Reuse
The proposed mixed-use redevelopment (Figure 2) will require demolition of current commercial
structures. Approximately 150,000 square feet of existing structures remain on-site as shown on
Figure 4. The PD proposes to dispose of masonry debris and vertical, above-grade, demolition
material at associated permitted facilities. Remaining on-grade concrete floor slabs and foundation
systems (herein referred to as “materials”) are proposed for potential on-site reuse relying on North
Carolina General Statute (NCGS) 130A-294(m)3 and 130A.301.34 as guidance, pending
evaluation of results from implementation of this Work Plan-MR. Approximate locations of

GC7466/CAR220110 3 07/2022
proposed reuse are shown on Figure 5 but may change within the Brownfields Property boundaries
as construction progresses.
Note that the PD also intends to reuse stone aggregate underneath asphalt paved areas and concrete
floor slabs and foundations. Because stone aggregate cannot be sampled, it has been excluded from
this Work Plan-MR. Field characterization of the stone aggregate for evidence of potential impacts
will be conducted per EMP requirements and existing assessment data will be evaluated to support
potential reuse and/or off-site disposal. Additional details will be provided in the Managed Reuse
Plan and EMP-1 that will be developed after implementation of this Work Plan-MR.
2. WORK PLAN-MR OBJECTIVE
Based on the history and regulatory status of the Site, the potential for the concrete to be impacted
by contaminants from historical activities needs to be evaluated to support its reuse in order to be
protective of human health and the environment. This Work Plan-MR was prepared to provide
procedures for sampling of concrete elements on the Site to support the preparation of the Managed
Reuse Plan. NCGS 130A-294(m) and 130A.301.3 were used as guidance to develop sampling
procedures and analysis proposed in this Work Plan-MR.
3. SAMPLING METHODOLOGY
Additional sampling will need to be conducted to support managed reuse. The sampling will only
apply to concrete and foundation materials. Since contaminants from historical dry-cleaning
operations are more likely present near the former dry-cleaning release source area, samples will
be collected for analysis of volatile organic compounds (VOCs) and semi-volatile organic
compounds (SVOCs) only in this area. This includes a limited portion of the 801 McDowell Street
property. These samples will be placed on hold, pending results of nearby soil samples. In other
areas of the Site, the potential presence of metals in building materials will be the focus of sampling
activities described in the following section of this Work Plan-MR to evaluate if these materials
can be reused at the Site consistent with the previously described regulatory guidance.
The work will be conducted in general accordance with the Occupational Safety and Health
Administration (OSHA) rules (29 Code of Federal Regulations [CFR] 1910.120). To address
potential underground utilities, Geosyntec will contact the North Carolina 811 one-call system a
minimum of 72 business hours in advance for clearing of public utilities. A private utility locator
may also be subcontracted to perform ground penetrating radar (GPR) and electromagnetics (EM)
to locate and mark subsurface utilities and rebar at the proposed building material sampling
locations at the Site. Final sampling locations may be modified, if necessary, based on utility
locations and/or other field conditions.
GC7466/CAR220110 4 07/2022
3.1. Foundation Sampling
Geosyntec will collect foundation concrete samples using a decontaminated rotary-impact drill
with a 5/8-inch diameter drill bit at 31 locations (FC-1 through FC-8 [two to four locations each]
and FG-1 through FG-5) across the Site as shown in Figure 4 and described in Table 1. Avoiding
the overlying tile layer (as applicable), fines produced from drilling through the concrete slab at
each location will be collected.
Approximately equal volumes of concrete fines will be collected from multiple locations as
designated in Figure 4 and Table 1. Materials will be mixed in a decontaminated stainless-steel
bowl, to generate composite samples FC-1 through FC-8 for metals analysis. Following
homogenization, samples will be submitted to a North Carolina-certified environmental laboratory
under chain of custody procedures and analyzed for Resource Conservation and Recovery Act
(RCRA) metals by Environmental Protection Agency (EPA) Method 6020 and 7471 and
hexavalent chromium by EPA Method 7199 as listed in Table 1.
Five (non-homogenized) discrete grab samples (FG-1 through FG-5) will be collected directly
from fines produced from drilling from the 801 South McDowell Street property as summarized
on Table 1 and depicted on Figure 4. A parts per billion-level photoionization detector (PID) will
be used to measure vapors from the hole through the slab by sealing off around the PID and
collecting a reading. Discrete grab samples will be submitted to a North Carolina-certified
environmental laboratory under chain of custody procedures and placed on hold for potential
analysis of VOCs using EPA Method 8260 and SVOCs using EPA Method 8270. Based on results
of nearby soil sample collection and PID readings, these samples may be analyzed. If dry cleaner-
related compounds are not detected in nearby soil samples collected during a different scope of
work, it will be assumed that the concrete does not contain VOCs or SVOCs.
If results of concrete sample totals analyses are above the NCDEQ Division of Waste Management
(DWM), Inactive Hazardous Sites Branch (IHSB) Residential, Commercial, or Protection of
Groundwater PSRGs for concrete sample constituents, Geosyntec may return to the Site and
collect additional grab and/or composite samples. These samples would be collected from
approximately the same locations as the parent samples (the totals analysis samples) and would be
submitted to the laboratory for EPA Method 1312 Synthetic Precipitation Leaching Procedure
(SPLP) analysis of the compounds with concentrations above PSRGs to evaluate leaching
potential.
Note that sampling does not include fuel storage areas, electrical transformer areas, or locations of
hydraulic elevators. Materials from these areas will not be reused; these materials will be
transported off-site to a permitted disposal facility. Floor tile and mortar layer (tile overlay) will
also not be reused.
GC7466/CAR220110 5 07/2022
3.2. Decontamination
Decontamination of reusable soil sampling equipment will take place prior to sample collection at
each grab sample location or composite group in accordance with Field Equipment Cleaning and
Decontamination LSASDPROC-205-R4 (LSASD, 2020). Prior to arrival on-Site, drill bit(s) will
be decontaminated. Drilling and sampling equipment including stainless steel bowls and spoons
for homogenization will be decontaminated prior to each use and in accordance with the following
cleaning procedures:
Physically remove grit or visible contamination using a brush or scrub pad
Wash equipment thoroughly with Alconox non-phosphate detergent wash in tap water
Rinse thoroughly with tap water
Rinse with distilled water
Air dry
Wrap in aluminum foil if not immediately re-using
Clean, disposable (vinyl or nitrile) gloves will be worn while handling sampling equipment and
tools during decontamination. Some general decontamination requirements will be followed to
provide the greatest protection from cross-contamination, recontamination, and quality control.
Decontamination will be conducted in a manner that will guard against cross-contamination of
equipment. Decontamination procedures performed during the field investigation will be
documented in the field logbook. Deviations from the standard decontamination protocols will be
noted.
4. LABORATORY ANALYSIS AND REPORTING
4.1 Laboratory Analysis
Collected concrete samples will be placed in laboratory-provided sample containers with sufficient
volume and submitted to a North Carolina-certified environmental laboratory under chain of
custody procedures (Section 4.2). Samples will be stored on ice following collection. Samples will
be analyzed by the laboratory for the constituents outlined in Table 1 with the methods listed in
the table notes.
4.2 Laboratory Reporting
Laboratory reporting limits (RLs) and method detection limits (MDLs) used by the selected North
Carolina-certified laboratory for methods will meet respective NCDEQ DWM IHSB Residential,
Commercial, and Protection of Groundwater PSRGs for totals analysis of concrete sample
constituents or Title 15A North Carolina Administrative Code (NCAC) Subchapter 2L.0202
GC7466/CAR220110 6 07/2022
standards (2L Standards) for SPLP analyses. Concentrations detected between the RL and MDL
will be reported as estimated values and flagged in the laboratory analytical report with a “J”.
Level II QA/QC will be reported in the analytical report deliverables.
5. QUALITY ASSURANCE AND QUALITY CONTROL
5.1 Field and Laboratory Procedure QA/QC
One blind duplicate concrete sample per 20 samples collected per method and medium will be
collected and submitted for laboratory analysis. The lab will be provided sufficient sample volume
for Matrix Spike/Matrix Spike Duplicate (MS/MSD) analysis.
5.2 Chain of Custody QA/QC
Geosyntec will initiate chain of custodies for concrete samples in the field documenting sample
collection information including but not limited to:
The Sample Collector’s Name;
Project Information and Location;
Geosyntec Project Manager Contact Information;
Sample Identification Number;
Date and Time of Sample Collection;
Type of Analysis; and
Type and number of containers and associated preservative, if applicable.
Samples will remain in the custody of Geosyntec until they are ready for shipment. Geosyntec will
relinquish the samples and chain of custodies (noting date and time of relinquishment) to the
laboratory courier (or use a custody seal during sample shipment) who will sign the chain of
custody as receiver (noting date and time again). Geosyntec will retain a copy of the chain of
custodies signed by the courier.
Sample coolers and the chain of custodies will be sealed in an appropriate shipping container/box
and sent to the address of the selected laboratory.
A representative from the selected laboratory’s sample receiving will sign respective chains of
custody verifying receipt of the samples by each respective laboratory location. A copy of fully
executed chains of custody will be provided in the final laboratory analytical report deliverable.
GC7466/CAR220110 7 07/2022
6. INVESTIGATION DERIVED WASTE (IDW) MANAGEMENT
IDW decontamination water will be containerized in Department of Transportation (DOT)-
approved 55-gallon drums and staged in secure designated areas of the Site in accordance with the
Soil and Water Management Memorandum (Geosyntec, 2022). IDW from this investigation may
be combined with IDW from other investigations at the Site. Sample laboratory data will be used
to characterize waste for transportation off-site at a permitted disposal facility in general
accordance with 15A NCAC 02T.1503 and the Site-specific Soil and Water Management
Memorandum (Geosyntec, 2022).
7. REPORTING
Upon receipt of laboratory results, Geosyntec will prepare a Managed Reuse Plan summarizing:
(i) the scope of work completed and sampling methodologies performed; (ii) tabulated concrete
sample laboratory analytical results; and (iii) lay-out the framework for the managed reuse of
foundation materials. Concrete sample results will be compared to NCDEQ PSRGs for
Residential, Commercial, and Protection of Groundwater standards for totals analysis. If SPLP
analysis is performed, results will be compared to 2L Standards. Analytical results may also be
evaluated using the January 2022 version of the NCDEQ Risk Calculator. The report will include
figures depicting the sample locations. The final report will be signed and sealed by a Professional
Engineer or Geologist and will include Geosyntec’s Professional Engineer and Professional
Geologist license numbers.
