1.0 Introduction
The Mecklenburg County Land Use and Environmental Services Agency Property (LUESA Property) is located at
the northeastern corner of the intersection of Suttle Avenue and Wilkinson Boulevard in Charlotte, North Carolina,
and has an associated address of 2145 Suttle Avenue. Refer to Figure 1, Site Vicinity Map and Figure 2,Site
Map. The LUESA Property, which Mecklenburg County owns, is subject to a recorded North Carolina Brownfields
Agreement (Project No. 06016-02-60 - under the name Radiator Specialty). The Radiator Specialty site consists of
approximately 27 acres, of which the LUESA property is located on the southeastern 10 acres. The LUESA Property
includes the approximate 114,000-square-foot LUESA office building and a paved parking lot with landscaped
islands.
S&ME was retained by Mecklenburg County AFM to provide environmental consulting services at the property
associated with the installation of electric vehicle (EV) chargers to the northeast of the LUESA office building. This
work was conducted under the guidance and requirements of a North Carolina Brownfields Redevelopment
Section (NCBRS) Environmental Management Plan (EMP) executed on November 2, 2023.
Based on several telephone calls and email messages between Mecklenburg County AFM, NCBRS, and S&ME,
several upcoming construction projects will require adherence to NCBRS regulations, which will include the
preparation of a new EMP and/or the revision of an existing EMP. These projects include:
The pending construction and installation of additional EV charging stations along the northern portion of
the parking lot.
The installation of an emergency generator on the southern portion of the property.
An upgrade to the existing irrigation system throughout the property.
During a conference call with Carolyn Minnich of the NCBRS, Samantha Allen of Mecklenburg County AFM, and
Patrick Laatsch of S&ME on March 6, 2024, the NCBRS requested the completion of a soil sampling event per an
approved Brownfields Work Plan prior to the preparation of an EMP for the upcoming construction
projects. Furthermore, it was requested that Mecklenburg County AFM prepare a general EMP that would apply
to future facility maintenance activities (to a depth of 5 feet) to avoid the need for a new EMP for every facility
project within the near surface. Based on follow up information and discussions, it was determined that the
proposed soil sampling event should cover the entire project area.
The following text summarizes the scope of work, field activities, analytical testing, and Brownfields
documentation that are proposed for the Brownfields Work Plan for the Limited Soil Assessment at the LUESA
Property.

2.0 Scope of Work
2.1 Basis and Approach
Based on discussions with Mecklenburg County AFM and the NCBRS and information provided by Mecklenburg
County AFM in March and April 2024, S&ME proposes to collect 10 composite soil samples throughout the
property to characterize the soil to provide information on soil management during future surface disturbances
during site construction/maintenance activities.
2.2 Project Management, Health and Safety Plan, and Coordination
Prior to mobilizing to the subject property to conduct the proposed sampling, S&ME will complete the following:
Prepare a health and safety plan (HASP) in accordance with 29 CFR 1910.120 as required by the
Occupational Safety and Health Administration (OSHA) to comply with the proposed site activities.
Coordinate with Mecklenburg County AFM for scheduling purposes and to ensure safe site access to
the proposed sampling locations.
Contract with a North Carolina-licensed driller to provide direct push technology (DPT) sampling
services at the site.
Obtain laboratory-prepared sample containers from a North Carolina certified laboratory.
2.3 Schedule
The field assessment activities are scheduled to begin in June 2024 (pending NCBRS approval of this Work Plan)
and are estimated to be conducted over two workdays.
In general, the field work will be initiated within two weeks of receipt of approval for this Work Plan. S&ME
anticipates submitting a draft summary of findings to Mecklenburg County AFM approximately one week after
receipt of the final laboratory report. The Limited Soil Assessment Report will be provided to the NCBRS within
three business days of receipt of comments and approval from Mecklenburg County AFM. S&ME will provide
project updates to Mecklenburg County AFM and to the NCBRS as the work progresses.
The general sampling schedule is presented in the following table:

3.0 Limited Soil Assessment Activities
3.1 Utility Clearance and Geophysical Survey
Prior to conducting intrusive activities, S&ME will contact the public utility locator (NC 811) to locate public
utilities. In addition, S&ME will contract with a private utility contractor to confirm public utilities, attempt to
locate private underground utilities, and clear each proposed boring location utilizing ground-penetrating radar
(GPR) and electromagnetic (EM) methods.
3.2 Assessment Guidelines
Sampling will be conducted in general accordance with the following guidance manuals:
NCDEQ Inactive Hazardous Sites Branch, Guidelines for Assessment and Cleanup of Contaminated Sites
(September 2023);
U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division Field
Branches Quality System and Technical Procedures (most recent version).
3.3 Soil Sampling
3.3.1 Sample Locations
The parking lot and vegetated areas at the LUESA Property have been divided into 10 sampling zones. See Figure
3, Proposed Composite Soil Sampling Zones. Previous sample locations within the general work area are shown
on Figure 4. Within nine of the 10 zones, five soil borings will be advanced to approximately 5 ft bgs. In Zone 7
(EV charging area), seven soil borings will be advanced to approximately 5 ft bgs. Two composite soil samples will
be collected in each of the 10 zones for a total of 20 soil samples.
3.3.2 Soil Boring Advancement
Upon completion of subsurface locating activities, S&ME will mobilize to the site with a North Carolina-licensed
driller to advance 52 soil borings to a depth of 5 ft bgs in the 10 zones described above. The borings will be
advanced utilizing a track-mounted DPT drill rig. Continuous soil samples will be collected via macrocore
samplers and will be logged for lithological description. The soil will be field screened for staining, odors, and
organic vapors utilizing a calibrated photoionization detector (PID) to measure volatile organics in each 2.5-foot
interval (0 ft bgs to 2.5 ft bgs and 2.5 ft bgs to 5 ft bgs). Soil collected from each boring location will be divided;
one half will be collected in a sealed plastic bag that is placed on ice within a cooler, and the other half will be
collected in a sealed plastic bag and placed in the sun to volatilize for approximately 5 to 10 minutes. After the
volatilization period, the headspace of the second plastic bag will be screened utilizing the PID.
A grab sample for each boring will be collected for the analysis of volatile organic compounds (VOCs) by
Environmental Protection Agency (EPA) Method 8260 from the corresponding sealed bag in the cooler that
exhibited the highest PID reading from each zone. For composite sample collection, soil from the sealed plastic

bags in each zone in the cooler will be composited using a decontaminated stainless-steel bowl and spoon. In
each zone, one composite sample from the 0 ft bgs to 2.5 ft bgs interval and one composite sample from the 2.5
ft bgs to 5 ft bgs interval will be collected (two total composite samples per zone). The soil samples will be placed
in laboratory-provided glassware and labeled with sampling identification for the analysis of semi-volatile organic
compounds (SVOCs) by EPA Method 8270, Resource Conservation and Recovery Act (RCRA) Metals by EPA
Method 6020, hexavalent chromium by EPA Method 7199, and PCBs by EPA Method 8082. In accordance with
NCBRS requirements, one duplicate soil sample per day will be collected from one sample location for the same
requested analyses. After collection, the grab, composite, and duplicate samples will be stored on ice in a
laboratory-provided cooler and submitted to a North Carolina-certified laboratory for testing. An aliquot of soil
(from each composite zone and each sample depth) will be collected and submitted to the laboratory for PCBs by
EPA Method 8082 and placed on hold in the event that additional analysis is requested by the NCDEQ. Refer to
Attachment III, Table 1, Summary of Sample Point Information.
The sampler will complete a chain-of-custody (COC) form provided by the laboratory. The sampler will sign where
indicated and record the site identification, sample number, date and time of sampling, matrix code, sample type,
and the analyses requested. When the custody of samples is transferred, the persons relinquishing and receiving
custody will sign, date, and record the time of transfer on the COC. If the samples are shipped using a commercial
courier, the bill of lading will become part of the COC and will serve as the signature of the person receiving the
samples.
After the soil sampling has been completed, each of the borings will be abandoned to the surface with bentonite.
The ground surface of each boring will be finished with asphalt, concrete, or soil, as applicable.
3.3.3 Quality Assurance/Quality Control
Per NCBRS guidelines, one duplicate is required to be sampled per 20 samples; therefore, one duplicate soil
sample per day will be collected for the same requested analyses.
The laboratory will provide Level II QA/QC analyses for this project, including reporting target analytes at
concentrations between the laboratory method detection limits (MDLs) and the laboratory reporting limits (RLs),
otherwise known as “J values.” To the extent feasible, the laboratory MDLs will not exceed the respective
regulatory standards and screening levels.
3.3.4 Investigative-Derived Waste
Soil cuttings will be containerized in 55-gallon drum(s) in accordance with 15A NCAC 02T.1503 and 15A NCAC
02H. 0106. If necessary, composite soil samples (frequency determined by disposal facility) will be collected from
the 55-gallon drums for analysis by the Toxicity Characteristic Leaching Potential (TCLP) and submitted to the
laboratory. Following receipt of the results and approval from the facility, the soil cuttings will be transported to
an approved facility for proper disposal.
