NORTH CAROLINA BROWNFIELDS REDEVELOPMENT SECTION
ENVIRONMENTAL MANAGEMENT PLAN
This form is to be used to prepare an Environmental Management Plan (EMP) for projects in
the North Carolina Brownfields Redevelopment Section at the direction of a Brownfields
project manager.
The EMP is a standard requirement of a Brownfields Agreement (BFA). Its purpose is to clarify
actions to be taken during demolition and construction at Brownfields properties in an effort
to avoid delays in the event of the discovery of new contamination sources or other
environmental conditions. The EMP provides a means to document redevelopment plans and
environmental data for each applicable environmental medium to inform regulatory-compliant
decision-making at the site. As much detail as possible should be included in the EMP,
including contingency planning for unknowns. Consult your project manager if you have
questions.
Prospective Developers and/or their consultants must complete and submit this form and all
pertinent attachments, see checklist below, to their Brownfields project manager prior to any
earthmoving or other development-related activities that have the potential to disturb soil at
the Brownfields Property, including demolition. For the EMP to be valid for use, it must be
completed, reviewed by the Section, signed by all parties working on the project, and
approved by the Brownfields project manager. Failure to comply with the requirements of the
EMP could jeopardize project eligibility, or in the event of a recorded agreement, be cause for
a reopener.
The EMP is valid only for the scope of work described herein and must be updated to be
applicable for new phases of redevelopment or after significant changes in applicable
regulatory guidance. Risk characterization of a Brownfields Property to DEQ’s written
satisfaction is required prior to EMP approval.
Voluntary Metrics Tab The NC Brownfields Redevelopment Section updates estimated capital investment (from the Brownfields Property Application) and estimated jobs created (from the Brownfields Agreement) whenever possible. As a voluntary measure, you may opt to complete the below information for capital investment and jobs created as estimated by your final redevelopment
plans for the Brownfields Property:
1.Estimated capital investment in redevelopment project: $60,000,000
2.Estimated jobs created:
a.Construction Jobs: 100
b.Full Time Post-Redevelopment Jobs: 8-10

At a minimum, contractors shall be made aware of protocols should impacted soils (e.g. staining,
unusual odors, fill materials) be identified.
Describe the field screening method, frequency of field screening, person conducting field
screening:
evidence of potential impacted soil. Evidence of potential impacted soil includes a distinct
unnatural color, strong odor, or filled or previously disposed materials of concern (i.e.
chemicals, tanks, drums, etc.). Should the above be noted during site work, the contractor
will contact the environmental consultant to observe the suspect condition. If the
environmental consultant confirms that the material may be impacted, then the
procedures below will be implemented. In addition, the environmental consultant will
contact the DEQ Brownfields project manager within 48 hours to advise that person of
Soil sample collection
☒ Yes
☐ Not anticipated - In order to avoid delays in construction, a plan shall be in place for sampling
of suspect soils should they be encountered during redevelopment. If soil sample collection is
not anticipated but the need to do so is identified during redevelopment, notify the Brownfields
project manager of the anticipated sample and report dates for scheduling purposes.
Describe the sampling method (e.g., in-situ grab, composite, stockpile, etc.) and confirm that all
procedures outlined in applicable DEQ guidance for assessment shall be followed Typically, at
least one representative sample (per 500 yd3 for residential and 1,000 yd3 for commercial)
consisting of a 3 to 5-point composite sample with grab sample for VOCs based on the highest PID
reading is required to determine soil management options:
removal of utilities, excavation will proceed only as far as needed to allow grading and/or
construction of the utility to continue.
Suspect impacted soil will be stockpiled in accordance with Appendix E: NCBP Diagram for
Temporary Containment of Impacted or Potentially Impacted Soil.
At least one representative composite soil sample (no less than 3 aliquot soil samples) at
a sample ratio of one soil sample per every approximately 500-cubic yards of soil will be
collected for analysis of total VOCs, SVOCs, and RCRA metals plus hexavalent chromium.
If the soil sample laboratory analytical results indicate that the soil could potentially
exceed toxicity characteristic hazardous waste criteria, then the soil will also be analyzed
by TCLP for those compounds that could exceed the toxicity characteristic hazardous
waste criteria.

☐ If no, include rationale here:
☐ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings
Other comments regarding managing impacted soil in utility trenches:
Soil samples collected during the collected during the Brownfields Assessment contained the
following constituents at concentrations exceeding state action levels:
VOCs: Tetrachloroethylene (samples B-1 at 3 feet bgs and B-2 at 3 feet bgs)
Metals: Arsenic (samples B-1, B-2, B-3, B-4, B-5, B-6, B-7, B-8, and B-9 at depths between 3 and
7 feet bgs).
Arsenic was detected in 12 soil samples, and given similar concentrations evenly distributed
over the site, arsenic is likely a naturally occurring element.
Should impacted soils be encountered in utility trenches, the procedures described above in Part
1A. Managing Onsite Soils will be implemented. The analytical results will be compared to the
respective Health Based Residential PSRGs and NCDEQ vapor intrusion screening levels, and the

CONTINGENCY PLAN
In this section, please provide actions that will be taken to identify or manage unknown
potential new sources of contamination. During redevelopment activities, it is not uncommon
that unknown tanks, drums, fuel lines, landfills, or other waste materials are encountered.
Notification to DEQ Brownfields project manager, UST Section, Fire Department, and/or other
officials, as necessary and appropriate, is required when new potential source(s) of
contamination are discovered. These Notification Requirements were outlined on Page 1 of this
EMP.
the findings of the Brownfields Assessment, it does not appear likely that contaminated indoor air
would be encountered during redevelopment activities. If potentially contaminated indoor air is
encountered, an industrial hygienist will assess the condition and determine what types of samples
(soil, soil vapor, sub-slab soil vapor, indoor air), if any, need to be collected. Worker protections could
include the installation of engineering controls during construction to recirculate outdoor air into the
building. Depending on the preliminary findings, Terracon will discuss options with the Brownfields
Program, and develop potential response options in accordance with Brownfields Program guidance.
22
EMP Version 3, March 2023
Should potentially impacted materials be identified that are inconsistent with known site
impacts, the DEQ Brownfields project manager will be notified, and a sampling plan will be
prepared based on the EMP requirements and site-specific factors. Samples will generally be
collected to document the location of the potential impacts.
Check the following chemical analysis that are to be conducted on newly identified releases:
☒Minimum Sample Requirements: Volatile organic compounds (VOCs) by EPA Method 8260;
Semi-volatile organic compounds (SVOCs) by EPA Method 8270; and Metals RCRA List +
Hexavalent Chromium by EPA Method 6020/7199
☐Pesticides: Specify Analytical Method Number(s):
☐PCBs: Specify Analytical Method Number(s):
☐Other Constituents & Analytical Method(s) (e.g. Herbicides)
Please note, if field observations indicate the need for additional analyses, they should
be conducted, even if not listed here.
Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
Underground Storage Tanks – Note that UST Section guidelines must be followed for sample
frequency during UST closure. Unless damage to onsite structures to remain as part of
redevelopment would occur, USTs shall be removed from the Brownfields Property:
environmental professional can visit the site. The environmental professional will assess the
situation and report to the DEQ within 48 hours of discovery. The tank will be inspected to
determine if any product remains in the tank. The contents of the tank will be evaluated, analyzed,
and disposed of at a licensed off-site facility in accordance with regulatory requirements and DEQ
approval. Unless an alternative approach is approved by DEQ, the tank will be removed in
accordance with applicable UST regulations. Following appropriate health and safety protocols
surrounding soil and soil at the base of the tank will be screened with a photoionization detector
(PID) and flame ionization detector (FID), the breathing zone will be monitored using a PID/FID,
and confirmatory soil sampling and/or remedial activities will be conducted to the
satisfaction of DEQ.
Sampling locations will be selected as outlined in the most recent version of Site Checks, Tank
Closure and initial Response and Abatement for UST Releases (UST Section, DEQ, Division of Waste
Management). Samples will be analyzed as referenced above, and impacted soil associated with
the UST will be managed in accordance with the Managing On-Site Soil section of this EMP.
Sub-Grade Feature/Pit:
23
EMP Version 3, March 2023
unusual odors or staining, construction activities will cease in the immediate area until an
environmental professional can visit the site. The environmental professional will assess the feature
and screen soils for the potential presence of volatile organic constituents using a PID. If it appears
that the sub-grade feature or pit contains impacted soils, a minimum volume of impacted soils
necessary to support construction will be removed and stockpiled on-site pending characterization.
For characterization, at least one representative composite soil sample (no less than 3 aliquot soil
samples) at a sample ratio of one soil sample per every approximately 500-cubic yards of soil will be
collected for analysis of total VOCs, SVOCs, and RCRA metals plus hexavalent chromium. Analysis
may include TCLP if deemed necessary for disposal purposes.
The sub-grade feature or pit will then be removed or backfilled in accordance with construction
specifications. Confirmation sampling will be conducted at representative locations in the base and
sidewalls of the excavation for the parameters noted above. The environmental professional will
notify the Brownfields Project Manager within 48 hours of discovery of the conditions encountered
Buried Waste Material – Note that if buried waste, non-native fill, or any obviously filled materials
is encountered, the DEQ Brownfields Redevelopment Section must be notified to determine if
investigation of landfill gases is required:
until an environmental professional can visit the site. The environmental professional will assess the
buried materials and screen soils for the potential presence of volatile organic constituents using a
PID, and methane using a flame-ionization detector (FID). The buried waste will be removed to the
extent practicable, and if it appears that impacted soils are present, only the volume of soils
planned to support construction at that location will be removed and stockpiled on-site pending
characterization.
For characterization, at least one representative composite soil sample (no less than 3 aliquot soil
samples) at a sample ratio of one soil sample per every approximately 500-cubic yards of soil will be
collected for analysis of total VOCs, SVOCs, and RCRA metals plus hexavalent chromium. Analysis
may include TCLP if deemed necessary for disposal purposes.
Confirmation sampling will be conducted at representative locations in the base and sidewalls of
the excavation for the parameters noted above. The environmental professional will notify the
Brownfields Project Manager within 48 hours of discovery and will report on the conditions
encountered and actions taken. If waste materials cannot be fully excavated their continued
presence will need to be evaluated from both a geotechnical perspective and for methane and/or
soil vapor generating potential. The environmental professional will contact the Brownfields
Project Manager for guidance.
Re-Use of Impacted Soils Onsite:
Please refer to Part 1.A above.
If unknown, impacted soil is identified onsite, management onsite can be considered after the
project team provides the necessary information, outlined in Part 1.A. Item 11, for Brownfields
project manager approval prior to final placement onsite.

1.0 INTRODUCTION
1.1 General Site Description
The site consists of eight parcels of land located in downtown Winston-Salem, Forsyth County,
North Carolina (Exhibit 1). The parcels are listed by Forsyth County as:
◼ Parcel ID No. 6835-39-4439: 951 N. Liberty Street, 0.44 acres
◼ Parcel ID No. 6835-39-5574: 923 N. Liberty Street, 1.25 acres
◼ Parcel ID No. 6835-39-7772: 0 N. Liberty Street, 0.83 acres
◼ Parcel ID No. 6835-39-7523: 331 N. Martin Luther King, Jr. Drive, 0.22 acres
◼ Parcel ID No. 6835-39-7585: 347 N. Martin Luther King, Jr. Drive, 0.22 acres
◼ Parcel ID No. 6835-39-8642: 0 Ivy Avenue, 0.17 acres
◼ Parcel ID No. 6835-39-8567: 916 Ivy Avenue, 0.08 acres
◼ Parcel ID No. 6835-39-8563: 0 N. Martin Luther King, Jr. Drive, 0.11 acres
The site properties comprise a total of 3.41 acres of land. The parcel at 923 N. Liberty Street is
developed with a commercial office/warehouse building that operated as a Carpet Warehouse
until April 2023. The site is bordered to the north by N. Liberty Street followed by Taylor’s
Warehouse and C&T Truck and Auto Repair, to the south by N. Martin Luther King Jr. Drive
followed by the Atrium Health Downtown Health Plaza, to the east by Ivy Avenue NE followed by
Salvage Building Materials and a vacant commercial building, and to the west by Patterson
Avenue followed by Truliant Federal Credit Union. The site configuration is shown on Exhibit 2.
The site was accepted into the North Carolina Brownfields Program (NCBP) on January 11, 2023.
The NCBP is the lead regulatory agency for this project.
1.2 On-site and Off-site Concerns
Terracon completed a Phase I Environmental Site Assessment (ESA) for the property and
provided our findings, conclusions and recommendations in a report dated June 7, 2022
(Terracon Project No. 75227075). The Phase I ESA identified the following Recognized
Environmental Conditions (RECs) potentially affecting the site:

Responsive ■ Resourceful ■ Reliable 2
REC/Site Concern Description
Historical Site Use
◼ The former Vine Dry Cleaners facility was reportedly located
adjacent to or on the site, as identified in the DRYCLEANERS
database and EDR’s proprietary Historical Cleaners
database. According to the Historical Cleaners database, the
Vine Dry Cleaners operated from at least 1970 through 1979.
The exact location (on-site or off-site) is unknown.
Potentially Up-Gradient
Off-site Concerns
◼ The Salvage Building Materials facility was formerly located
approximately 50 feet north and topographically up-gradient
relative to the site and is identified in the State Hazardous
Waste Sites (SHWS) database, and the Incident
Management Database (IMD). Two gasoline USTs and one
Kerosene UST were closed by removal, leaving a waste oil
UST in the ground. A groundwater sample from a monitoring
well contained the chlorinated solvent trichloroethylene (TCE)
and the volatile organic compound chloroform at
concentrations exceeding 15A North Carolina Administrative
Code (NCAC) 2L Groundwater Quality Standards (2L
Standards). Based on the lack of documentation concerning
the source or extent of the chlorinated solvent Terracon
considers the former Salvage Materials facility to represent a
REC to the site.
◼ The 893 North Liberty Street / 747 North Chestnut Street
facility located approximately 70 feet west and topographically
cross-gradient relative to the site is identified in the U.S.
Brownfields database. Other records or reports for this facility
were not identified or made available. Based on distance and
gradient relative to the site and the lack of information
regarding the US Brownfields listing Terracon consider it to
represent a REC to the site.
Terracon subsequently completed a Brownfields Assessment at the site and provided our
findings, conclusions and recommendations in a report dated October 11, 2023 (Terracon Project
No. 75227127). The assessment included the collection of 18 soil samples and five groundwater
samples for volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs),
eight Resource Conservation and Recovery Act (RCRA) metals, and hexavalent chromium
analyses. Sixteen soil vapor samples (nine exterior and seven sub-slab) were collected and
analyzed for VOCs.
Final Grade Sampling Work Plan

March 1, 2024 ■ Terracon Project No. 75227127
Responsive ■ Resourceful ■ Reliable 3
The assessment identified several VOCs and three SVOCs in soils reported at concentrations
above the laboratory Method Detection Limits (MDLs). Tetrachloroethylene (PCE) was detected
in four soil samples; two at concentrations exceeding the Protection of Groundwater Preliminary
Soil Remediation Goal (PSRG). Hexavalent chromium was reported in the 3-foot below ground
surface (bgs) soil sample collected from soil boring B-5 at a concentration exceeding the
Residential Health-Based PSRG. Arsenic was detected in every soil sample at concentrations
exceeding the Residential Health-Based PSRG or the Protection of Groundwater PSRG.
The groundwater samples collected from monitoring wells MW-1 and MW-5 were reported to
contain PCE at concentrations exceeding the 2L Standard. The groundwater sample collected
from monitoring well MW-5 also was reported by the laboratory to have three VOCs at
concentrations above the 2L Standards. SVOC analytes were reported in the groundwater sample
collected from monitoring well MW-3 at concentrations as “J” qualified data exceeding the 2L
Standards. Arsenic was detected at a concentration above the 2L Standard in the sample from
monitoring well MW-3, and chromium was detected in one groundwater sample (MW-5) at
concentrations above the 2L Standard.
Soil vapor concentrations were elevated in vapor samples SVP-1, SVP-2, and SVP-3, which may
be evidence of a historical dry-cleaning operation on or near the site in this location. Soil vapor
samples SVP-1, SVP-2, and SVP-3 contained elevated soil vapor concentrations of several
VOCs, including vinyl chloride and trichloroethylene (TCE). Due to the elevated VOC
concentrations in these three vapor samples, the laboratory dilutions were high, and some of the
MDLs exceed the NCDEQ sub-slab and exterior soil gas screening levels (SGSLs).
The Risk Calculator indicated that, for direct contact with soil and water, the carcinogenic and
hazard index risk values were not exceeded for site residents or non-residential workers. For
vapor intrusion, the carcinogenic and hazard index risk values were exceeded for residents for
the soil gas to indoor air pathway. The hazard index, but not the carcinogenic risk, exceeded the
residential groundwater to indoor air pathway and the non-residential soil gas to indoor air
pathway. The residential hazard indices for vapor intrusion were calculated to be above 1.0.
2.0 SCOPE OF WORK
Assessment activities at the site did not identify on-site sources of contamination, and the site is
not being regulated by other North Carolina environmental agencies. Therefore, it is Terracon’s
understanding that the primary concern of the NCBP is how human health could be affected
during and after redevelopment activities at the site. The purpose of the final grade sampling
activities is to ensure that areas of shallow soil that will remain exposed following construction at
the site do not contain VOCs, SVOCs, or metals at concentrations exceeding NCDEQ health-
based action levels.

Sample locations were selected based on the available planned exposed soil areas based on
Based on Terracon’s review of the Overall Landscape Plan prepared by Stimmel Associates and
dated January 18, 2023, the landscape plan shows a total planter area of approximately 20,840
square feet. Terracon proposes to collect a total of six final grade grab samples and six final grade
composite samples across six areas of undeveloped soil on the site (Exhibit 2). Terracon will use
the most recent IHSB Program Guidelines for Assessment and Cleanup of Contaminated Sites
as a protocol for the assessment activities. Terracon has included the completed NCBP Minimum
Requirement Checklist for Site Assessment Work Plans and Reports in Appendix A.
The assessment will generally consist of the following elements:
◼ Revise existing Health and Safety Plan
◼ Advance 18 soil borings (3 each in 6 general areas) with a decontaminated hand auger to
depths of 2 feet below ground surface (bgs)
◼ Collect soil samples from the 1-2 foot boring interval
◼ Screen soil samples for VOCs using a photoionization detector (PID)
◼ Collect one grab soil sample with the highest relative PID reading from the 3 borings
advanced in each area (6 grab samples total) for VOC analysis.
◼ Prepare one composite sample using equal aliquots of soil from the 3 soil samples
advanced in each area (6 composite samples total) for SVOC and metals analysis
◼ Interpret data
◼ Prepare and submit assessment report
The soil borings will be advanced in the approximate locations shown on the attached Exhibit 2.
We divided the site into 6 general areas based on the layout of the apartment buildings. The
borings are not intended to address any specific areas of concern at the site because none were
identified during the Brownfields Investigation. There are three courtyard areas with planters (one
with a pool), and planter areas located around the buildings and site perimeter. The borings will
be advanced with a decontaminated hand auger to depths of approximately 2 feet bgs. Soil
samples will be collected in the 1-2 foot soil boring interval.

Please refer to the attached Table 1 for the proposed sampling and analysis plan. The proposed
boring locations may be modified in the field to account for utility clearance, access limitations,
and/or site conditions. The client will be notified of any significant modifications to the sampling
locations.
The hand auger will be cleaned using an Alconox® detergent wash and potable water rinse prior
to commencement of the project and after collection of each sample. The sample locations
(horizontal control only) will be documented by a North Carolina licensed surveyor.
3.0 SAMPLING METHODS
Soil sampling techniques outlined in this work plan are in general accordance with the NCDEQ,
IHSB Guidelines for Assessment and Cleanup of Contaminated Sites dated September 2022.
The soil samples will be inspected to document lithology, color and relative moisture content. Soil
type, relative moisture content, and other lithologic characteristics will be documented in field
notes only; boring logs will not be prepared in the field based on the shallow depth of the borings
and the presence of fill soils in the planters. Terracon will screen the soils in the field using a PID
that detects and quantifies volatile vapors. In the event that soil samples from a boring exhibit
elevated PID readings, the sample collected with the highest PID reading in each designated area
will be collected for analysis.
Soil samples will be collected at the depth intervals described in the Sampling and Analysis Plan
(Table 1). The soil samples will generally be collected in the 1- to 2-foot interval of soils present
in the selected planter areas. The soil samples will be placed into laboratory-supplied glass
containers, labeled with pertinent sample information with a permanent marker and stored in an
ice-packed cooler pending submittal to Pace Analytical Laboratories in Mt. Juliet, Tennessee, a

North Carolina certified laboratory. Chain of custody documentation will accompany the samples
to the laboratory.
Soil sample results will be compared to the IHSB’s Preliminary Soil Remediation Goals (PSRGs)
for unrestricted use and residential use. Additionally, constituent concentrations in the soils will
be evaluated using the NC Brownfields Program’s Soil Risk Calculator under Residential and
Non-Residential exposure scenarios.
4.0 SAMPLE ANALYSES
A total of 6 soil samples will be analyzed by Pace Analytical laboratory located in Mount Juliet,
Tennessee (NC Laboratory Accreditation No. Env375). Six grab samples, one from each of 6
designated site areas, will be analyzed for VOCs using USEPA Method 8260. Six composite soil
samples, one from each of 6 designated site areas, will be analyzed for SVOCs using USEPA
Method 8270, eight Resource and Recovery Act (RCRA) metals using USEPA Method 6010,
mercury using USEPA Method 7471 and hexavalent chromium using USEPA Method 7199.
Level II Quality Assurance/Quality Control (QA/QC) data packages will be provided from the
laboratory for all analyses.
5.0 QUALITY ASSURANCE / QUALITY CONTROL
Laboratory samples will be analyzed in conjunction with standard laboratory QA/QC procedures
including appropriate blanks, duplicates, continuing calibration standards, surrogate standards,
and matrix spiking standards in accordance with approved methodologies to monitor both
instrument and analyst performance. The laboratory will include estimated concentrations for
compounds that are detected at levels above the laboratory detection but below the laboratory
reporting limit (J flags). Laboratory results not meeting reporting limits with be identified within
the QA/QC discussion of the report.
Based on the number of samples to be collected, field duplicate samples will not be collected or
analyzed, and a trip blank will not be analyzed as part of the project.
A level II QA/QC data package will be requested from the analytical laboratory for the soil
samples. Terracon will require that laboratory reporting limits (RL) and Method Detection Limits
(MDL) be below applicable standards and screening levels, to the extent feasible. Terracon will
also request “J-Flag” values to be included in the laboratory analytical reports.
6.0 INVESTIGATION DERIVED WASTE MANAGEMENT
Following the completion of sampling activities, each soil boring will be properly abandoned in
general accordance with applicable USEPA Region 4 SESD Guidance Document dated January
Final Grade Sampling Work Plan
Carpet Warehouse ■ Winston-Salem, NC
March 1, 2024 ■ Terracon Project No. 75227127

2018. Based on the boring depths of 2 feet bgs and the presence of fill soils, the borings will be
abandoned using the soil cuttings removed during the hand auger boring process. Soil cuttings
generated during the assessment activities that exhibit PID readings in excess of 50 parts per
million (referenced to an isobutylene standard) will be stored in 55-gallon drums pending proper
characterization and disposal.
7.0 FINAL GRADE SAMPLING REPORT
Upon completion of the assessment activities and receipt of the laboratory analytical results, a
Final Grade Sampling Report will be prepared that will include the following items:
▪ Documentation of field activities;
▪ Site plan showing pertinent site features;
▪ Analytical laboratory results;
▪ Data evaluation and presentation of findings including comparison of data to applicable
regulatory standards; and
▪ Recommendations concerning further assessment, if necessary
The report will be completed in a format suitable for submittal to the NCBP. Work associated with
this scope of services will be performed under the direction of, and the final report will be signed
and sealed by a Professional Geologist registered in the State of North Carolina.

NCDEQ Brownfields Program – February 2022
Instructional Page
All references to Prospective Developers includes follow-on owners who may be conducting
work in accordance with the Brownfields Property Management Unit.
To increase predictability and most efficiently assess Brownfields Properties and the redevelopment
timing requirements of Prospective Developers or follow-on owners, the Brownfields Program 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 Program’s completeness review. This checklist outlines the minimum requirements and
submittal format under the Brownfields Program for Assessment Requirements and Reporting. All
Assessment Work Plans and Reporting submissions to the Brownfields Program 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
Program prior to implementation. However, in order to respect the schedule of all projects in house
and keep the program’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.

Reviewed and checked by (Name ): _______________________________________
Title Page
The title page should include the following information. Letter style reports are acceptable, as long as this
information is somewhere on the first page.
X Title of Work Plan
X Brownfields Project Name (not the development name)
X Brownfields Project Number
X Date (updated with each revision)
X Revision Number
X Firm PE/PG License Number
X Individual PE/PG seal & signature
X Contact information for Developer, Consultant, and Project Manager
Section 1 – Introduction
X Provide the site location, address, and acreage.
X Provide a BRIEF summary of the history of the property and its history in the program. For example:
reiterate RECs from a Phase I ESA, indicate if the scope of work was negotiated during a Data Gap
Meeting, etc.
X Briefly list and describe the data gaps the assessment is attempting to fill
X Indicate if the assessment data is for the use of any other DEQ programs in addition to the
Brownfields Program (i.e. the site is a regulated UST, IHSB, etc. property)
Section 2 – Scope of Work
X Provide a general description of proposed scope of work covered in this plan (i.e. 2 new monitoring
wells, six groundwater samples, 5 exterior soil gas sampling points and 6 soil borings)
X Discuss samples to be collected by media and source area/location. Generally, the reasoning for the
sample locations selected.
X Describe depths of samples to be collected (Reference Table 1) or how that decision will be made
in the field, if needed.
X State for what each sample will be analyzed (briefly). Reference Table 1.
- For all residential reuses, sub slab vapor is required, if no slabs exist, exterior soil gas is required
within all proposed footprints.
Section 3 – Sampling Methodology
X Reference the guidance documents you intend to use. IHSB, EPA SESD, VI Guidance, Well
Construction Rules (NCAC 2C). Note deviations or methodology planned that is not covered by
such guidance (e.g., multi-increment sampling, passive air samplers, mobile labs, Hapsite,
simultaneous indoor/outdoor radon, high-volume subslab vapor testing, PFAS sampling).
X Describe what will be installed (soil boring, temporary well, permanent well, sub slab vapor, exterior
soil gas, etc.). Include construction details.
X Discuss installation methodology (Hand Auger, DPT, etc.)
X Discuss sample collection procedures. Include the following, at a minimum:
• Equipment to be used
• Purging methods and volumes
Work Plan and Report Checklist
Version 2 February 2022
• Stabilization parameters for groundwater sampling
• Field screening methods
• Leak check procedures for sub-slab vapor and exterior soil gas samples (Note this is
required)
• Discuss how and when vacuum readings will be collected (for summa cans)
X Discuss sample point abandonment
Section 4 – Laboratory Analyses
X Discuss the proposed analyses (include method number, preparation method, if there are concerns
with short hold times, etc).
X Discuss any proposed limitations on the contaminants of concern, if any, and the reason for such
limitation (sufficient previous data, indoor air interferences, etc).
X Discuss laboratory certifications. Please note, NC does not certify labs for air samples. Please
specify what certification the proposed air lab holds.
X Indicate that the Reporting Limits/Method Detection Limits will meet applicable screening criteria
(to the extent feasible). Include Reporting of J-Flags to meet criteria.
X Indicate what Level QA/QC will be reported by the laboratory. Level II QA/QC is typically
acceptable.
Section 5 – QA/QC
X Specify the duplicate sample frequency. Minimum requirement: 1 duplicate per 20 samples, per
media, per method.
Discuss Trip Blank. 1 Trip Blank per cooler/shipment of groundwater VOC analyses is required.
X Discuss how the lab will have sufficient sample volume for MS/MSD analyses.
X Discuss chain of custody and shipping.
Section 6 – Investigation Derived Waste (IDW) Management
X Discuss what IDW will be generated and how it is proposed to be managed. Management
recommendations should be in accordance with 15A NCAC 02T.1503 and 15A NCAC 02H. 0106.
Generally, if the Brownfields Property has not previously been assessed, then all IDW must be
containerized and characterized prior to management. Previous assessment data that indicate no
Hazardous Waste (listed or characteristic) is likely to be encountered in the area of proposed
assessment will be required before thin spreading of IDW on-site is permitted.
Section 7 – Reporting
This section should discuss the components of the assessment report which will be prepared as a result of
the above sample collection. At a minimum, the report shall include:
X Reporting/summary of site work conducted for all sections outlined above in this checklist;
X Summary of findings and possible recommendations;
X All applicable tables and figures outlined below with the addition of:
Tables for tabulated analytical data per media sampled and analyzed, compared against
applicable screening levels, sample depths and depth to groundwater;
Figure depicting actual sample locations collected, with each media depicted in the legend,
graphic scale and north arrow; and
Groundwater potentiometric map, with graphic scale and north arrow.
- Boring logs for all soil borings, newly constructed monitoring wells, and exterior soil gas locations
- Well construction and abandonment records, if applicable
