Minimum Requirements Checklist
Site Assessment Work Plans and Reports
NCDEQ Brownfields Redevelopment Section– March 2023
Instructional Page
All references to Prospective Developers include follow-on owners who may be conducting
work in accordance with the Brownfields Property Management Branch.
To increase predictability and most efficiently assess Brownfields Properties and the redevelopment
timing requirements of Prospective Developers or follow-on owners, the Brownfields
Redevelopment Section has standardized the format for Site Assessments. This format has been
generated in the form of a checklist to allow for ease in submission by the prospective developer’s
consultant and for the Brownfields Redevelopment Section’s completeness review. This checklist
outlines the minimum requirements and submittal format under the Brownfields Redevelopment
Section for Assessment Requirements and Reporting. All Assessment Work Plans and Report
submissions to the Brownfields Redevelopment Section must include this completed checklist in the
outlined format.
These requirements allow DEQ to reduce review time for the Assessment Work Plan and Report
and increase process predictability for prospective developers. This checklist will also provide
reliable data for risk-based decisions and further expedite the project timeline. Any divergence from
these requirements will lengthen the process of assessing risks on the site, may necessitate
reprioritization of a project manager’s queue towards projects that meet these requirements.
Therefore, delaying production of the brownfields agreement and/or environmental management
plan. Any alterations to the checklist on a site-specific basis must be reviewed and approved by the
Section prior to implementation. However, in order to respect the schedule of all projects in house
and keep the Section’s entire project pipeline moving, we strongly recommend against seeking
changes to the checklist.
Based on a review of environmental and risk data from our project inventory, please note
there are some new points of emphasis that are included herein:
1. For ALL residential reuses; sub-slab vapor assessment (full list EPA TO-15) is required,
regardless if existing structures will be removed. If no structures or slabs exist on the
Brownfields Property, exterior soil gas assessment is required within all proposed structure
footprints.
2. ALL properties require groundwater data (VOCs, SVOCs and RCRA Metals) from a
minimum of three sample locations, depth to groundwater and a resulting potentiometric
map.
3. Soil shall be assessed based on areas of concern and redevelopment plans and across the
depth interval of the cut/grading.

Final Grade Soil Sampling Work Plan – Revision 1 Kaiser Fluids Tech II
Former Henkel Chemical Corporation 4100 Raleigh Street Charlotte, North Carolina H&H Job No. T&U-002
1.0 Introduction and Background
On behalf of Trailhead 4100 Owner, LLC (Prospective Developer or PD), Hart & Hickman, P.C.
(H&H) has prepared this Final Grade Soil Sampling Work Plan (Work Plan) for the former
Henkel Chemical Corporation portion of the Kaiser Fluids Tech II Brownfields property
(Brownfields Project No. 20026-16-060) located at 4100 Raleigh Street in Charlotte,
Mecklenburg County, North Carolina (Site). The Site consists of an approximately 3.8-acre
parcel (Parcel ID No. 09107204) of land that is being redeveloped for various commercial
purposes including retail, restaurants, art galleries, music venues, breweries, and/or co‐working
spaces. A Site location map is provided as Figure 1.
The Site was initially occupied by Standard Chemical between approximately 1953 and the early
1960s, and was used for the production of textile manufacturing chemicals. Henkel Chemical
Corporation, a subsidiary of Standard Chemical, occupied the Site between the early 1960s and
early 1990s. Henkel Chemical also formulated textile manufacturing chemicals, including
various fiber and yarn lubricants, dyeing and finishing auxiliaries, and assistants. Henkel
Chemical vacated the Site in the early 1990s, and the Site remained vacant until 1998. Between
the late 1990s and 2021, the Site was occupied by several building supply companies, a recycling
company, an art studio, and a real estate development company.
The Site and north adjacent property (former Kaiser Fluids Technologies; 530 E. Sugar Creek
Road) received eligibility for entry into the North Carolina Department of Environmental Quality
(NC DEQ) Brownfields Program in June 2017. H&H and the Prospective Developer at the time
(Sugar Creek Station, LLC) discussed data gaps with DEQ Brownfields personnel and
subsequently completed two phases of assessment activities in accordance with the Brownfields
2
s:\aaa-master projects\third & urban\t&u-002 4100 raleigh street (former henkel)\final grade soil sampling\work plan\revision-1 to deq\final grade soil sampling work plan_rev 1.doc
Program in October 2018 and February 2019. The assessment activities included collection of
soil, groundwater, exterior and sub-slab soil gas, indoor air, and building material samples for
laboratory analysis. A brief summary of the results of the previous assessment activities is
provided below.
Groundwater Assessment
The results of previous assessment indicated the presence of 1,4-dioxane, pentachlorophenol or
PCP, and chromium (total) in groundwater in the northern portion of the Site at concentrations
above the North Carolina 2L Groundwater Quality Standards (2L Standards).
Please note that mercury was reported during the October 2018 sampling event in one sample
(MW-3) at a concentration above the 2L Standard and vapor intrusion screening level. However,
mercury was not detected in MW-3 or its duplicate sample during the February 2019 sampling
event.
Vapor Intrusion Assessment
The results of previous vapor intrusion assessment activities indicated the chlorinated volatile
organic compound (VOC) tetrachloroethylene or PCE was detected in one exterior soil gas
sample collected from the west-central portion of the Site at a concentration above the DEQ
Residential Soil Gas Screening Level (SGSL) but below the Non-Residential SGSL. In addition,
the petroleum-related compound xylenes (m,p- and o-) were detected in multiple exterior soil gas
samples at concentrations above the Residential SGSLs but below the Non-Residential SGSLs.
The results of cumulative risk calculations for the exterior and sub-slab soil gas samples indicate
acceptable carcinogenic and non-carcinogenic risks under both residential and non-residential
use scenarios.
The results of indoor air samples collected from the Site building did not indicate mercury was
detected in any of the samples at concentrations above laboratory method detection limits.

Soil Assessment and Cleanup
The results of previous assessment activities indicated the presence of polychlorinated biphenyls
(PCBs) in soil in two distinct areas of the Site (former catch basin and former laboratory), and on
a portion of a concrete building slab in the former boiler room of the existing warehouse. PCBs
were detected at concentrations above the EPA’s Toxic Substances Control Act (TSCA)
unrestricted cleanup level of 1 milligram per kilogram (mg/kg). The “Areas of Known PCB
Contamination” are depicted on the Brownfields plat.
To comply with the PCB cleanup requirements specified in the EPA’s TSCA regulations
established in 40 CFR Part 761, H&H completed bulk PCB remediation waste cleanup activities
at the Site between May 2022 and July 2022. The primary goal for the cleanup was to address
bulk PCB remediation waste at the Site to prevent unacceptable health risks to future users of the
Site in accordance with 40 CFR 761.61(b) for a performance-based cleanup and disposal of bulk
PCB remediation waste under TSCA.
The cleanup activities included the removal and off-Site disposal of 539.82 tons of soil, concrete,
and debris to a TSCA-approved chemical waste landfill (TSCA landfill) located in Emelle,
Alabama. Analytical results of 161 final verification samples collected in accordance with 40
CFR 761 Subpart O indicate that the cleanup objective was achieved at each cleanup area and no
further action is required at the Site to meet TSCA requirements. Since the remaining PCB
impacts are below the TSCA unrestricted cleanup level of 1 mg/kg following the performance-
based cleanup, the remediated areas are authorized for use under 40 CFR 761.30(u) and will be
managed in accordance with the DEQ-approved Environmental Management Plan (EMP) dated
May 3, 2019.
A Notice of Brownfields Property, which includes the Brownfields Agreement, land use
restrictions, and Brownfields plat was recorded for the Site at the Mecklenburg County Register
of Deeds on July 15, 2021.
Redevelopment activities at the Site are nearing completion, and final grade elevations have been
established across the Site. In accordance with the DEQ-approved EMP, final grade soil
4
s:\aaa-master projects\third & urban\t&u-002 4100 raleigh street (former henkel)\final grade soil sampling\work plan\revision-1 to deq\final grade soil sampling work plan_rev 1.doc
sampling will be conducted at the Site following redevelopment in areas that are not covered
with buildings, pavement, or permanent hardscape. The purpose for the final grade soil sampling
is to evaluate potential direct exposure risks to future Site occupants and workers from shallow
soil at the Site. A DEQ Brownfields Redevelopment Section – Assessment Work Plan Approval
Signature Page is included as Appendix A. The proposed final grade soil sampling activities are
outlined in the following sections.
2.0 Final Grade Assessment Activities
Exposed soil at the Site is limited to landscaped and grassy areas surrounding the Site buildings,
grassy areas along the Site perimeter, and in landscaped parking lot islands. H&H will collect
shallow soil samples for laboratory analysis in representative unpaved areas to evaluate the
potential for impacts. The Site redevelopment plan and associated unpaved areas are shown in
Figure 2 and a copy of the Site plan is provided in Appendix B.
The soil sampling activities will be conducted in general accordance with the DEQ Inactive
Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of Contaminated Sites
(Guidelines) dated September 2022, the most recent versions of U.S. Environmental Protection
Agency (EPA) Region IV Laboratory Services and Applied Science Division (LSASD) Field
Branches Quality System and Technical Procedures guidance, and the enclosed DEQ
Brownfields Redevelopment Section’s Minimum Requirements Checklist dated March 2023.
2.1 Final Grade Soil Sampling Activities
Based on review of the Site plan and observations at the Site, unpaved portions of the Site have
been divided into eight (8) final grade evaluation areas (FG-1 through FG-8). Four to five
shallow soil borings will be advanced within each final grade evaluation area. Soil sample
aliquots collected from each evaluation area will be homogenized to form one composite soil
sample to represent shallow soil conditions in that evaluation area. The final grade evaluation
areas and approximate locations of the aliquot soil borings are presented on Figure 2 and sample
details are provided in Table 1.
5
s:\aaa-master projects\third & urban\t&u-002 4100 raleigh street (former henkel)\final grade soil sampling\work plan\revision-1 to deq\final grade soil sampling work plan_rev 1.doc
Aliquot soil borings will be advanced from the surface to approximately two feet below the
ground surface (ft bgs) using a decontaminated stainless-steel hand auger. During boring
advancement, continuous soil samples will be collected from the center of the hand auger bucket.
Soil samples will be described for lithologic purposes, observed for obvious evidence of staining
and unusual odors. A portion of the soil sample will be allowed to volatilize and will be field
screened for the presence of volatile organic vapors using a calibrated photoionization detector.
The remaining portions of the aliquot soil samples will be homogenized to form a composite soil
sample representative of each evaluation area for a total of eight (8) composite final grade soil
samples. Soil samples selected for laboratory analysis will be collected directly into laboratory
supplied glassware, labeled with the sample identification, date, and requested analysis, and
placed in a laboratory supplied cooler with ice. The samples will be delivered to a North
Carolina certified laboratory under standard chain of custody protocols within 48 hours of
sample collection for the analyses outlined below.
Composite soil samples will be submitted for laboratory analysis of semi-volatile organic
compounds (SVOCs) by EPA Method 8270, polychlorinated biphenyls (PCBs) by EPA method
8082, and Resource Conservation and Recovery Act (RCRA) metals plus hexavalent chromium
by EPA Methods 6020/7471/7199. In addition, one grab sample will be collected from an
undisturbed portion of an aliquot soil sample collected in each evaluation area for a total of eight
(8) grab soil samples that will be submitted for analysis of VOCs by EPA Method 8260.
The grab samples collected for VOC analysis will be selected based on results of field screening
and collected from the aliquot exhibiting the highest likelihood for impact in each final grade
evaluation area. If field screening results do not identify obvious presence of impacts in an
aliquot soil sample, the final grade evaluation area grab samples will be collected from the 1 to 2
ft bgs sample interval from a randomly selected aliquot soil boring in each evaluation area.
Following sample collection, the soil borings will be properly abandoned, and the ground will be
restored to match the surrounding surface.

2.2 Quality Assurance/Quality Control
Non-dedicated equipment and tools will be decontaminated prior to use at each boring location.
To evaluate the reproducibility of the sample results, H&H will collect one duplicate soil sample
per day of sampling that will be submitted for the same analyses as the parent soil sample.
Laboratory QA/QC procedures will be employed to ensure appropriate sample handling and
analysis and to aid in the review and validation of the analytical data. QA/QC procedures will be
conducted in accordance with the method protocols and will include regular equipment
maintenance, equipment calibration, and adherence to specific sample custody and data
management procedures.
Samples will be analyzed in conjunction with appropriate blanks, laboratory duplicates,
continuing calibration standards, surrogate standards, and matrix spiking standards in accordance
with approved methodologies to monitor both instrument and analyst performance. H&H will
request that laboratory method detection limits for each analyte be at or below the DEQ IHSB
Residential Preliminary Soil Remediation Goals (PSRGs), where possible. Additionally, H&H
will request that the laboratory include estimated concentrations for compounds that are detected
at levels above the laboratory method detection limit, but below the laboratory reporting limit (J
flags). Adequate sample volume will be collected for the laboratory to perform MS/MSD
analyses.
The laboratory analytical data report and QA package for the final grade soil samples submitted
to and analyzed by the subcontracted laboratory will be provided in an appendix to the final
report. Laboratory QA data consistent with Level II documentation will be requested for this
project. A copy of the completed chain-of-custody record and shipping receipt will be appended
to the corresponding laboratory analytical report included with the final report.

2.3 Investigation Derived Waste
Based on previous assessment data and the results of cleanup activities performed at the Site,
hazardous waste (listed or characteristic) is not expected to be encountered during the final grade
soil sampling event. Therefore, investigation derived waste (IDW) generated during the final
grade assessment activities will be thin spread on-Site. However, if significant impacts are
suspected based on field screening results, the soil cuttings will be containerized in a 55-gallon
drum and staged on-Site pending analytical results of a composite IDW sample. Based on
laboratory analytical results of IDW sample, the drum will be transported off-Site to a suitable
facility for disposal. IDW generated during the proposed assessment activities will be managed
in general accordance with DEQ IHSB Guidelines.
2.4 Reporting
Following completion of the final grade soil assessment for the Site, a report which describes the
methods and results of the final grade soil sampling activities will be prepared and submitted to
DEQ. The report will include a title page, description of field activities, field screening results, a
tabular summary of the analytical results in comparison to the PSRGs, risk calculations, boring
logs in tabular form (will include boring IDs, field screening/PID results, and soil descriptions),
figures depicting the sample locations, laboratory analytical reports and chain of custody records,
field notes, a discussion of QA/QC data, and conclusions based upon our assessment activities.
The report will be sealed by a North Carolina Professional Engineer (PE) or Professional
Geologist (PG) and the firm PE/PG numbers will be provided.
