EMP Version 2, January 2021  
NORTH CAROLINA BROWNFIELDS PROGRAM 
ENVIRONMENTAL MANAGEMENT PLAN 

This form is to be used to prepare an Environmental Management Plan (EMP) for projects in 
the North Carolina Brownfields Program at the direction of a Brownfields project manager. 

The EMP is a typical requirement of a Brownfields Agreement (BFA).  Its purpose is to clarify 
actions to be taken during the 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 resultant EMP to be valid for use, it 
must be completed, reviewed by the program, 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 completed 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.   

Voluntary Metrics Tab 
The NC Brownfields Program 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:

This EMP has been prepared specifically to support the Early Grading and Demolition phase of 
the project (Phase 1A‐01/Design Package D‐1) for select parcels on the Brownfields property as 
shown on Figure 2. The approximate limits of land disturbance are described under Item 3. 
Attachment A provides the mapped area where work under Phase 1A‐01/Design Package D‐1 
will be conducted for this project. As shown in this attachment there are currently several 
additional sub‐phases of work (1A‐02 onwards) planned for this project with more to come. 
Separate EMPs will be prepared for the additional phases of work.

detailed plans are not available. EMP review without such information would be premature): 
 Provide brief summary of redevelopment plans, including demolition, removal of building 
slabs/pavement, grading plans and planned construction of new structures:  
See attached Figure 3 for the location, layout, and land uses for the proposed development on 
the Brownfields Property. Figure 1 also provides an aerial view of the approximate location of 
existing features on the Brownfields Property including the existing buildings and infrastructure.

EMP Version 2, January 2021  
Note that this EMP includes Early Grading and Demolition (Phase 1A‐01/Design Package D‐1) of 
the area and existing buildings shown on Figure 2. Proposed grading detail and cut and fill 
analysis are included in Attachment C. 

Summary of Plans: The Brownfields Project will be redeveloped as part of the Pearl Innovation 
District and Atrium Health / Wake Forest Center for Education. This mixed‐use development will 
include an amenity plaza, multifamily housing, classrooms, faculty and commercial offices, 
research facilities and laboratories, a hotel, retail, and parking. Additional EMPs will be prepared 
for the previously described phases of development (Attachment A) and will include details 
about utility installation, foundations, vapor intrusion mitigation design, etc. once Site 
redevelopment plans are further developed.  

Under this EMP as part of the Phase 1A‐01/Design Package D‐1 scope of work, the PD will 
demolish seven existing office buildings and associated exterior parking and curbs. Building 
demolition will allow for early grading of the properties shown on Figure 2. The buildings have 
been assessed for the presence of asbestos‐containing materials (ACM) and are being assessed 
for the presence of hazardous materials. Prior to demolition, ACM and hazardous materials will 
be removed as part of the building decommissioning process. Asphalt will not be reused onsite 
and will be transported offsite to a permitted facility. Concrete from the building foundations 
may be reused onsite. If this option is selected, Geosyntec will provide a Manage‐Reuse Plan for 
NCDEQ approval. Documentation of the building decommissioning process will be included in the 
EMP report. 

Currently, Baxter Street represents a low elevation area within the Brownfields Property and the 
grading operations conducted under this initial phase of work will raise Baxter Street and lower 
other areas to provide a more even elevation surface for future construction. Sediment and 
erosion control measures will be set up during this phase of work per applicable requirements 
(see Attachment C). Based on available data, demolition and grading activities are unlikely to 
encounter the water table during this phase of work, and as such, are unlikely to encounter the 
well‐documented groundwater plume in Figure 4A. Current grading plans indicate that import of 
soil will likely not be needed, however, a soil import plan has been included in this EMP in case 
import of soils is needed to support the project.  

As shown in Attachment A, the initial grading work conducted under this EMP, as well as utility 
and culvert work performed under subsequent phases of work and EMPs, will include a portion 
of Baxter Street and South McDowell Street. These streets are right‐of‐ways owned by the North 
Carolina Department of Transportation (NCDOT, South McDowell Street) and the City of 
Charlotte (Baxter Street) and are not part of the Brownfields Property. Because these roadways 
are part of the overall redevelopment project from a site design and construction management 
standpoint (in coordination with the City of Charlotte who is in process of obtaining ownership of 
South McDowells Street from NCDOT) it is not practical to manage soils from the roadways 

8 
EMP Version 2, January 2021  
differently than soil from the Brownfields Property. As such, the procedures described in this 
EMP include management of soil for the entire project area shown under Attachment A and 
Figure 2 that include both the roadways shown on Figure 5 and the Brownfields Property. Field 
screening and sampling of soils, stockpile and final grade (landscape) sampling, the use of 
impervious surfaces to cover a majority of the Site, the design and installation of Vapor Intrusion 
Mitigation Systems (VIMS) and use of Land Use Restrictions (LURs) will be used to evaluate and 
manage risks in connection with the proposed reuse of the Site and roadway areas. 

As described in this EMP, a North Carolina Dry‐Cleaning Solvent Cleanup Act (DSCA) Program 
release incident (Former Domestic Laundry DSCA I.D.#DC600012) is located onsite. Soil and 
groundwater impacts are present and will need to be managed under this EMP and subsequent 
EMPs. Additionally, groundwater impacts from likely unknown offsite sources have also been 
identified through previous assessment. Due to the presence of a DSCA site on the Brownfields 
Property, soil and water management practices for this Brownfields Site were presented in a Soil 
and Water Management Memorandum submitted to the NCDEQ Brownfields Program, DSCA 
Program, and Hazardous Waste Section on 28 April 2022 which was approved on 4 May 2022. 
This memorandum provides additional regulatory details about management of soil and water 
and is included under this EMP as Attachment D. As described in this EMP, limited petroleum 
impacts are also likely present at the Site.    

 As described in this EMP, a net excess of soil separate from the DSCA area (which will be 
managed under the Contained‐in Policy) may be generated during this initial phase of work. 
Excess soils from outside of the DSCA area will be stockpiled onsite and sampled for possible 
reuse onsite during future phases of work, for possible export to another site and/or disposal at 
a permitted facility. If screening of excess soils from outside of the DSCA area show signs of 
potential significant impact or display potential for characteristic hazardous waste, then soils will 
either be left in place until characterized or placed in approved containers and then 
characterized. Area A soils from the Brownfields Property will be managed under the Contained‐
In Policy based on pre‐characterization data as described in Attachment D. 

4) Do plans include demolition of structure(s)?: 
   ☒ Yes  ☐ No ☐ Unknown  
☒ If yes, please check here to confirm that demolition will be conducted in accordance with 
applicable legal requirements, including without limitation those related to lead and asbestos 
abatement that are administered by the Health Hazards Control Unit within the Division of Public 
Health of the North Carolina Department of Health and Human Services.  If available, please 
provide a copy of your demolition permit.  

Hazardous materials surveys are being conducted for the buildings and materials such as light 
ballasts, mercury containing materials, and ACM, will be removed prior to demolition and disposed 
offsite. Backup generators with above ground storage tanks (ASTs) and piping and associated 

9 
EMP Version 2, January 2021  
infrastructure will be decommissioned by emptying the ASTs and disposing of residual petroleum 
and equipment offsite. An Environmental Professional (EP) will be present during AST 
decommissioning and will conduct field screening with a photoionization detector (PID) as 
described in the following sections of this EMP. Details for the decommissioning process will be 
included in EMP reporting. 

5) Are sediment and erosion control measures required by federal, state, or local regulations? 
  ☒ Yes    ☐ No    ☐ Unknown  
☒  If yes, please check here to confirm that demolition will be conducted in accordance with 
applicable legal requirements.  If soil disturbance is necessary to install sediment and erosion 
control measures, they may not begin until this EMP is approved.  

6) Which category of risk‐based screening level is used or is anticipated to be specified in the 
Brownfields Agreement?  Note: If children frequent the property, residential screening levels shall 
be cited in the Brownfields Agreement for comparison purposes. 
☒ Residential   ☐ Non‐Residential or Industrial/Commercial 
From a conservative planning standpoint, data will be compared to residential risk‐based screening 
criteria though substantial portions of the site will be non‐residential and non‐residential standards 
may be used for some areas such as 801 South McDowell St., 801, 821, 831, and 841 Baxter St., and 
943 Baxter St. Risk‐based evaluations will be conducted to demonstrate that the Site is safe for the 
proposed uses of the Site.  If non‐residential standards and screening levels are used for select 
areas of the Site, these areas will be specified in the Brownfields Agreement Plat Map and LURs will

11 
EMP Version 2, January 2021  

Tabulated data summaries for each impacted media are included in Tables 1 through 3. Sample 
locations are shown in Figures 4A, 4B, and 4C. Materials management practices for this Brownfields 
Site were presented in a Soil and Water Management Memorandum submitted to the NCDEQ 
Brownfields Program, DSCA Program, and Hazardous Waste Section on 29 April 2022 which was 
approved on 4 May 2022 (Attachment D). In this memorandum, portions of the Site are divided into 
three distinct areas in connection with documented release of contaminants from a known onsite DSCA 
release incident and apparent release(s) from unknown offsite sources – Area A which represents 
potential onsite DSCA‐related soil contamination; Area B which represents saturated soils impacted by 
groundwater contamination likely originating from the DSCA release incident; and Area C which 
represents saturated soils impacted by groundwater contamination from likely unknown offsite 
source(s) (Figure 6). The memo provides details on how to manage soils and water from these areas 
including flow charts on sample characterization and options for disposal or re‐use. This memorandum 
has been included as part of this EMP (Attachment D). 

Note that memorandum Areas A, B and C do not cover the entirety of the Phase 1A‐01/Design Package 
D‐1 project area. As such, areas not depicted in the memorandum will be managed in the same manner 
as Area C (Figure 6). There are no known releases of contaminants in this area and field screening and 
sampling will be used to manage soils from this area during construction. Environmental assessments 
completed to date, as presented in Tables 1 through 3 and Figures 4A, 4B, and 4C, do not indicate 
releases on the Brownfields Properties other than the documented DSCA release and 1997 LUST at 801 
South McDowell Street. 

PART 1. Soil 
1) Known or suspected contaminants in soil (list general groups of contaminants): 
 Chlorinated solvents (tetrachloroethene [PCE] is above the residential Preliminary Soil 
Remediation Goal (PSRG) in one sample and above the industrial/commercial PSRG in 
another sample, both from the former DSCA site source area) 
 BTEX (benzene, toluene, ethylbenzene and xylene) or other petroleum‐related 
compounds (trace toluene, chlorobenzene, and benzene below residential PSRGs remain 
beneath a former UST incident from 1997) 
 VOCs/SVOCs (detections of volatile organic compounds and semi‐volatile organic 
compounds, benzo(a)pyrene above the residential PSRG in six samples) 
 Metals (hexavalent chromium is above the residential PSRG in approximately half of 
samples, arsenic is above the residential PSRG in all but four samples, and arsenic is 
above the industrial/commercial PSRG in one sample. These metals may be naturally 
occurring) 
See Table 1 and area of soil impacts in Figure 4B.  

As defined in the Soil and Water Management Memo (Attachment D), soils will be defined as 
solid materials which are dry enough that free liquid does not separate from the materials. If free 
liquid separates from the material, it will be defined as mud. A slurry will be defined as a 
combination of water into solid material that results from mixing of materials. In the context of 
in‐situ sampling, soil above the historically high water table (based on historical monitoring well 

12 
EMP Version 2, January 2021  
gauging data) are considered unsaturated soils while soil below the historically high water table 
are considered saturated soils impacted by the underlying groundwater plume (as applicable). 

2) Depth of known or suspected contaminants (feet): 
Unsaturated soil impacts range from 0 (i.e. immediately below paved/impervious surfaces) to 20 
feet below ground surface, decreasing with depth. Saturated soils impacted by groundwater 
contaminants are unlikely to be encountered during this phase of construction. 

3) Area of soil disturbed by redevelopment (square feet): 
Approximately 714,000 square feet (19.5 acres). See Figure 2. 

4) Depths of soil to be excavated (feet): 
Up to 11 feet for this phase of grading (see Attachment C). The water table is anticipated to be 
between 10 and 25 feet below ground surface (due to topographic changes at the site) under 
non‐pumping conditions (when local dewatering for a nearby sewer installation construction 
project is not underway). The water table is not anticipated to be encountered during the early 
grading and demolition work included in this EMP including construction of sediment basins 
which are only anticipated to reach up to 11 feet from existing grade. Additional details 
regarding depths to groundwater and apparent impacts to groundwater elevations from current 
construction dewatering can be found in Geosyntec’s Limited Brownfields Environmental Site 
Assessment – Part I report (24 February 2022). If groundwater is encountered, the procedures in 
Part 2 of this EMP will be followed. 

5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): 
47,650 cubic yards to be disturbed during grading and reused onsite. 

6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:             
Up to 1,870 cubic yards from Area A though, as shown in Figure 4B, the area of soil impacts 
above Residential and Commercial PSRGs is a small portion of this area. These soils will be 
characterized in accordance with a NCDEQ approved sampling work plan and managed under the 
Contained‐In Policy per the previously described memo. Additional areas of impacted soil, if 
encountered during construction, will be managed in accordance with this EMP.  

7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:   
Grading plans describe approximately 8,400 cubic yards of excess soils but additional soils may 
need to be exported due to geotechnical unsuitability or contamination. As described below, 
soils will be characterized onsite through field screening and sampling (as needed) to evaluate 
and select soil management options. 

Part 1.A. MANAGING ONSITE SOIL 
If soil is anticipated to be excavated from the Brownfield Property, relocated on the Brownfields 
Property, or otherwise disturbed during site grading or other redevelopment activities, please

EMP Version 2, January 2021  
provide a grading plan that clearly illustrates areas of cut and fill (approximate areas & volumes are 
acceptable, if only preliminary data available).   

1) HAZARDOUS WASTE DETERMINATION:  
a) Does the soil contain a LISTED WASTE as defined in the North Carolina Hazardous 
Waste Section under 40 CFR Part 261.31‐261.35?....................................... ☒Yes   ☐No 
☒ If yes, explain why below, including the level of knowledge regarding processes 
generating the waste (include pertinent analytical results as needed). 
As described in the Soil and Water Management Memo (Attachment D), the 
Former Domestic Laundry DSCA site is likely a contributing source for a portion 
of the identified groundwater contaminant plume (Area B). In addition, 
contaminated soils within Area A (which includes unsaturated soils within the 
source area and former footprint of the Domestic Laundry facility) are  
considered to be associated with the DSCA release. These soils will need to be 
managed during Phase 1A‐01/Design Package D‐1 grading activities. As 
previously discussed, the water table is unlikely to be encountered during 
construction for Phase 1A‐01/Design Package D‐1 activities. However, 
procedures have been included in this EMP to manage saturated soil and 
groundwater in the event they are encountered during Phase 1A‐01/Design 
Package D‐1 construction activities. 

As described in the memo, soils and muds within Area A (as applicable) will be 
managed under the North Carolina Contained‐In Policy. These materials will be 
containerized by the Contractor in approved roll‐offs with plastic liners and 
gasketed doors (or 55‐gallon drums for small volumes), characterized by EP, and 
managed based on analytical results. If soils exhibit a hazardous waste 
characteristic or exceed hazardous waste contained‐out levels, they will be 
disposed offsite at a hazardous waste facility. If not, soils will be either disposed 
offsite as non‐hazardous waste (if soils meet the Contained‐In Policy Municipal 
Solid Waste Landfill [MSWLF] criteria), reused on‐site (if there are no detections 
of dry‐cleaning related compounds in soils and all detections are below 
hazardous waste characteristic levels using the 20‐times rule), or reused offsite 
(if there are no detections of dry‐cleaning related compounds in soils and 
concentrations are acceptable based on NCDEQ Risk Calculator results). 

For select soils within Area A, the PD has collected in‐situ characterization 
samples under a separate sampling work plan approved by NCBP on 30 June 
2022. Pre‐characterization sampling results will be compared to the criteria 
listed above to evaluate soil disposal or reuse options. A soil management and 
disposal plan will be submitted to NCDEQ for review and approval prior to 
moving Area A soils.

EMP Version 2, January 2021  
☒ If yes, do the soils exceed the “Contained‐Out” levels in Attachment 1 of the 
North Carolina Contained‐In Policy?................................................. ☒ Yes   ☐ No 
Select soils from Area A are anticipated to potentially exceed levels in Attachment 1 
of the Contained‐In Policy and these soils will be disposed at an appropriate 
facility based on pre‐characterization sampling analytical results. The majority of 
soils encountered outside of Area A (DSCA impacted soils) during Early Grading 
and Demolition are anticipated to be below the levels for disposal in a municipal 
solid waste landfill and will be evaluated using risk‐based criteria for potential on‐
site re‐use. 

b) NOTE: IF SOIL MEETS THE DEFINITION OF A LISTED HAZARDOUS WASTE AND EXCEEDS

Additional comments:  
As described in the Soil and Water Management Memo (Attachment D), DSCA area soils (Area 
A) will be containerized under the Contained‐In Policy or pre‐characterized and analytical 
results will be compared to the MSWLF criteria and/or Table 1 of Title 40 CFR Part 261.24.  

Soils not impacted by the DSCA release (Areas B and C ‐ unsaturated soils) may be reused per 
the field screening criteria presented below and/or pre‐characterized by the EP to further

redevelopment activities based on soil sampling data and field screening during previous 
assessment activities. However, the grading contractor will take into account conditions 
such as wind speed, wind direction, and moisture content of soil during soil grading 
activities to minimize dust generation. Contractors will implement dust control measures as 
needed based on Site and atmospheric conditions. Dust control measures may include 
water application, hydro‐seeding, and/or mulch, stone, or plastic cover.

Field Screening of site soil 
☒ Yes, describe the field screening method, frequency of field screening, person conducting 
field screening:  
Prior to beginning initial grading activities, the EP will attend a pre‐construction kick‐off 
meeting with the PD and site contractors to discuss the DEQ‐approved EMP and describe 
scenarios when it would be appropriate and necessary to notify the EP of the discovery of 
potentially impacted media or unknown subsurface features at the Site. During 
construction, an EP will be present for initial grading activities to make field observations 
and field screen soils using PID headspace and ambient air methods to evaluate for 
evidence of impacts, particularly during excavation of soil from Area A, soils in the deepest 
areas of demolition and grading, and areas closest to a former underground storage tank 
(UST). Based on field observations, the following onsite soil reuse criteria apply to the Site: 
 DSCA Area Unsaturated Impacted Soil (Area A): Regardless of field screening 
results, soils within this area will need to be managed in accordance with the Soil 
and Water Management Memo (Attachment D) using the Contained‐in‐policy.   
 Non‐DSCA Unsaturated Soils (Areas B and C): Soils with no evidence of field 
impacts may be reused onsite without additional sampling if they are used under 
Survey data as needed 

17 
EMP Version 2, January 2021  
impervious surfaces and/or under the final two‐feet of cover soil. As described 
under the following Soil Sample Collection section of this EMP, soils may be 
sampled to provide additional information for use as the final 2 feet of cover soil 
for non‐impervious areas and to assist in making soil management decisions for 
reuse on other portions of the Site. 

As described in the following soil Sample Collection section of this EMP, additional 
characterization of soils may be required to assist in the soil management decision‐making 
process. 

EP Field Screening Frequency: The level of on‐site EP oversight may decrease if initial 
screening results consistently suggest a lack of impacts. The NCBP will be notified of a 
reduction in the field screening frequency. 

Based on previously discussed existing assessment data, it is unlikely that an EP will be 
required on‐site for all earthwork activities. Based on initial observations during 
construction, the EP will work with the PD and construction personnel (Contractor) to 
determine the scope and frequency for subsequent oversight to reasonably document that 
remaining soils are managed in accordance with this EMP. This may include the EP moving 
to standby and relying on the site Contractor or contractor designated representative to 
notify the EP if field conditions are encountered that could indicate the potential presence 
of impacted soil (i.e. staining or odor). While the EP is on standby, the Contractor or 
designated representative will fill out a weekly log approved by the EP and provide photo 
logs (as necessary) to document Brownfields Property conditions. Weekly logs will 
continue until the Early Grading and Demolition earthwork is complete, regardless of the 
timeline presented above. The weekly reports will be included in a final EMP 
Implementation Report at the end of the Early Grading and Demolition phase of the 
project. While on standby, the EP will initially make weekly site visits, at a minimum, to 
document Brownfields Property conditions reported by the Contractor. The need and 
frequency of standby EP visits will be adjusted as needed based on site conditions 
encountered during site construction.

Soil Sample Collection 
☒ Yes, describe the sampling method (e.g., in‐situ grab, composite, stockpile, etc.):  
As discussed above and in the Soil and Water Management Memo (Attachment D), 
unsaturated soils within Area A that could potentially be impacted by dry‐cleaning solvent 
will be managed using the Contained‐In Policy which will include sampling of 
containerized soils for the chemical analytes listed below. 

18 
EMP Version 2, January 2021  

Unsaturated soils in Area C and above the water table in Area B were pre‐characterized 
and analytical results are included in Table 1 with sample locations shown in Figure 4B. 
Based on data presented in the Limited Brownfields Environmental Site Assessment 
Report – Part I (Geosyntec, 24 February 2022), risks by direct exposure to impacted soil 
was not exceeded for potential non‐residential workers, construction workers, or 
recreators for soils outside of the DSCA source area. If elevated reporting limits for three 
compounds not detected at the site (hexachlorobenzene, 4,6‐dinitro‐o‐cresol and 
hexachloropentadiene) are removed from consideration, the residential risk is also within 
acceptable limits. This data suggests that these soils are available for onsite reuse either 
under impervious surfaces or as soil cover for non‐impervious areas based on the field 
screening described above. As will be presented in a future EMP, final grade sampling will 
be conducted for any areas where the final development is not covered by an impervious 
surface or at least 2 feet of demonstrable clean fill. 

If needed based on insufficient analytical data, field visual or olfactory indication of 
impacts, or changes in conditions, additional characterization of unsaturated soils for 
Areas B and C may be conducted. This will include either stockpiling of soils for sampling 
and/or additional pre‐characterization of soils using direct push technology (DPT) drilling 
or hand auger methods to the approximate depth of anticipated soil disturbance. 
Additional details are provided below: 

In‐Situ Pre‐Characterization: If needed based on insufficient analytical data, field visual or 
olfactory indication of impacts, or changes in conditions, soils will be pre‐characterized 
prior to being disturbed by grading activities. Soil samples will be collected and screened 
with a PID. As needed, grab sample will be collected from the sample collected from the 
depth interval with the highest PID reading for the analytical methods described in this 
EMP. Analytical results will be evaluated using the Waste Management Risk Calculator to 
assist in further developing soil management options for onsite reuse.  

Stockpile Sampling:   

 Potentially Impacted Soil: If field evidence (i.e. staining, odor, or PID results) 
indicate the potential presence of soil impacts that are not consistent with 
previous assessment findings, the soil will be stockpiled for sampling unless the 
field evidence suggests it may be characteristic hazardous waste. Soil exhibiting a 
potential hazardous waste characteristic will be containerized. Stockpiled soil will 
be sampled, and, based on results, will either be transported to a NCDEQ 
permitted facility or evaluated using the Risk Calculator for management options. 
Stockpiled soil will be managed in an area designed in accordance with Figure 1 of 
this EMP; alternative stockpile containment designs may be proposed for NCDEQ 

19 
EMP Version 2, January 2021  
review and approval.  
 Non‐Impacted Soil: If field evidence does not indicate the presence of impacts, 
the soil can be reused onsite without additional sampling or stockpiling or placed 
into stockpiles for additional testing to obtain data to assist in further developing 
soil management options for onsite reuse. As needed, the data will be used to 
identify soil suitable for use for the 2 feet of cover soils for non‐impervious areas 
and for reuse under buildings or other onsite purposes. The goal is to obtain 
additional data to manage soils to be protective of construction workers and 
future Site occupants.  

For all stockpile sampling, segregation methods will be utilized by the Contractor to 
reasonably separate debris from soil. Stockpile sampling will be conducted in general 
accordance with NCDEQ guidance using the analytical laboratory methods included in the 
Soil and Water Management Memo and listed below. 

This EMP assumes that soils being re‐used on the Brownfields property can be 
transported across Baxter Street and stockpiled on the northern side of 801, 821, 831, 
and 841 Baxter Street which are proposed to be part of the Brownfields property. A map 
of the proposed stockpile area and roadways over which these soils may travel is included 
in Figure 5. With NCDEQ approval, containerized soils from Area A or below the water 
table in Area B may also be temporarily staged next to the stockpile area while waiting for 
analytical results. NCDEQ will be contacted prior to re‐locating potentially hazardous 
waste across a public right‐of‐way.   

As previously discussed, soil from designated City right‐of‐ways for portions of South 
McDowell and Baxter Street will be managed in the same manner as soils from the 
Brownfields property. Field screening and additional sampling data will be used, as 
needed, to demonstrate that the soil is suitable for onsite reuse. In addition, final grade 
sampling will be conducted upon completion of construction activities to further evaluate 
cover soils for non‐impervious portions of the Site.

Part 1.B. IMPORTED FILL SOIL 

NO SOIL MAY BE BROUGHT ONTO THE BROWNFIELDS PROPERTY WITHOUT PRIOR APPROVAL 
FROM THE BROWNFIELDS PROGRAM.  According to the Brownfields IR 15, “Documenting 
imported soil (by sampling, analysis, and reporting in accordance with review and written 
approval in advance by the Brownfields Program), will safeguard the liability protections provided 
by the brownfields agreement and is in the best interest of the prospective developer/property 
owner.” 

Requirements for importing fill: 

1) Will fill soil be imported to the site?................................................ ☐ Yes  ☐ No  ☒ Unknown 

2) If yes, what is the estimated volume of fill soil to be imported?  
At this time, it is anticipated that no fill soil will need to be imported onto the Site. The need for 
and volume of fill soil to be imported will depend on the geotechnical and analytical properties of 
on‐site soils. If it is determined that fill soil will be imported to the Site, the name and location of 
the source, along with a sample location map and analytical results, will be provided for NCBP 
approval prior to importing soil onto the Brownfields Property. 

3) If yes, what is the anticipated depth that fill soil will be placed at the property? (If a range 
of depths, please list the range.) 
In the event that fill soil is needed, it is estimated that between 0 and 5 feet of fill are anticipated 
during Early Grading and Demolition to fill former building foundations and smooth site 
topography. 

4) Provide the source of fill, including: location, site history, nearby environmental concerns, 
etc. Attach aerial photos, maps, historic Sanborn maps and a borrow source site history: 
 If needed, these materials will be obtained from a site where available environmental history has 
been reviewed and materials have been sampled prior to import. Methods for evaluating import 
soils are described in Item 7 under this section. 

5) PRIOR TO ITS PLACEMENT AT THE BROWNFIELDS PROPERTY, provide a plan to analyze fill 
soil to demonstrate that it meets acceptable standards applicable to the site and can be 
approved for use at the Brownfields property. 
In the event that import soil is needed, the methods described in Item 7 under this section will 
be used to analyze fill soil to demonstrate that it meets acceptable standards.

7) The scope of work for import fill sampling may be provided below or in a Work Plan 
submitted separately for DEQ review and approval.  Attach specific location maps for in‐situ 
borrow sites.  If using a quarry, provide information on the type of material to be brought 
onto the Brownfields Property. 
Soil samples will be collected using either a hand auger, an excavation bucket (when Site 
conditions, such as a tall stockpile, create a health and safety concern with using hand tools), or a 
drill rig. The rate of sample collection will be based on site conditions, and each site will be 
categorized as being either: (i) a site with available historical environmental data; (ii) a site with 
no historical environmental data; and (iii) Division of Energy, Mineral and Land Resources 
(DEMLR) virgin quarry already approved by NCBP. Soil sample collection rates or “sample 
volume” (SV) are outlined below: 
 Sites with historical environmental assessment data: approximately 1 soil sample per 
every 1,000 cubic yards (CY) of import soil. 
 Sites with no historical environmental assessment data: 1 soil sample every 500 CY of 
import soil.  
 DEMLR virgin quarry soil: One soil sample total.   
Regardless of site category, either in situ sampling will occur by advancing soil borings in a grid‐
like pattern within target area(s) to an appropriate maximum depth of the SV or soil borings will 
be collected from a stockpile. Three to five soil borings will be collected within each SV and will 
be advanced across the total depth of that SV (based upon the geometry of the potential import 
soil). Note that for DEMLR virgin quarry soil there will just be one SV and a reasonable depth will 
be selected. Soils will be screened continuously (at least every 1 foot) for evidence of total VOCs 
using a PID.  Soils will also be geologically classified in general conformance with the Unified Soil 
Classification System (USCS).  Field screening results will be included in boring logs that will be 
included in the relevant report documentation. 

One discrete grab sample will be collected for VOC analysis from the soil boring within each SV 
with the highest field screening results using laboratory supplied grab sample equipment (i.e., 
Terra Core® or equivalent) for VOC analysis by EPA Method 6020.  The discrete grab sample will 

23 
EMP Version 2, January 2021  
not be collected from composited soil. Remaining soil from soil borings collected within each SV 
will be homogenized in a decontaminated stainless‐steel bowl, or equivalent, and placed into 
laboratory‐supplied bottle wares for analysis of the following parameters:  

 SVOCs by EPA Method 8270; 
 RCRA 8 metals by EPA Methods 6020 and 7471; and 
 hexavalent chromium by EPA Method7199.  
Bottles will be labeled with sample ID that includes information regarding the sample location, 
sample depth interval, and sample date. The bottles will be placed on ice and submitted to a 
North Carolina National Environmental Laboratory Program (NELAP)‐certified laboratory for 
analysis following chain‐of‐custody procedures.   

Part 1.C. EXPORTED SOIL 

NO SOIL MAY LEAVE THE BROWNFIELDS PROPERTY WITHOUT APPROVAL FROM THE 
BROWNFIELDS PROGRAM.  FAILURE TO OBTAIN APPROVAL MAY VIOLATE A BROWNFIELDS 
AGREEMENT CAUSING A REOPENER OR JEOPARDIZING ELIGIBILITY IN THE PROGRAM, 
ENDANGERING LIABILITY PROTECTIONS AND MAKING SAID ACTION POSSIBLY SUBJECT TO 
ENFORCEMENT.  JUSTIFICATIONS PROVIDED BELOW MUST BE APPROVED BY THE PROGRAM IN 
WRITING PRIOR TO COMPLETING TRANSPORT ACTIVITIES.  Please refer to Brownfields IR 15 for 
additional details.  

1) If export from a Brownfields Property is anticipated, please provide details regarding the 
proposed export actions.  Volume of exported soil, depths, location from which soil will 
be excavated on site, related sampling results, etc. Provide a site map with locations of 
export and sampling results included. 
Exported soil will likely be limited to impacted soil identified by the EP based on field screening 
or by sampling. Exported soil could also include soil that is geotechnically unsuitable for re‐use. 
At this time, if impacted soil from Area A or below the water table in Area B is encountered, the 
soil will be exported to a NCDEQ permitted facility for disposal purposes. Pending stockpile 
sampling results and Brownfields Program approval, unsaturated and/or saturated soils from 
Areas B and C may be exported to another site.  

In addition to soils, tree roots that have been in contact with impacted soils (Area A soils or soils 
with visible or olfactory signs of impacts) will be transported off‐site for disposal at a permitted 
disposal facility. Laboratory test results representative of the areas containing the tree roots will 
be used to characterize the material for disposal purposes. Based on permit requirements for the 
selected disposal facility, additional analyses may be required for waste characterization 
purposes. Tree roots from Areas B and C, along with above‐grade portions of the trees, are 

24 
EMP Version 2, January 2021  
anticipated to be unimpacted and will be either chipped onsite or transported off‐site for 
disposal or reuse pending EP field screening results.   

Data to Support Soil Export to Another Site:  

Additional soil sampling may be necessary to obtain representative data for soil being exported if 
additional data is needed to evaluate if the Brownfields Property soil increases risk at the 
receiving property. Soil above the water table outside of Area A that is intended for export will 
either be sampled (or has been sampled) in place or will be stockpiled and then sampled. 
Stockpile sampling will be conducted in accordance with NCDEQ guidance using the analytical 
laboratory methods included in the Soil and Water Management Memo to support this effort. 
Results will be compared to the Waste Management Risk Calculator to evaluate soils for 
potential re‐use and will be evaluated based on the type of receiving site/facility and the risks 
posed by the chemical concentrations in the source Site soils compared to the receiving site soils. 
Additional NCBP and Solid Waste Section correspondence and approval will be required to 
establish data needs and sampling frequency. The sampling strategy and level of effort for 
sampling export soils typically depend on the characteristics of the receiving site. Additional 
correspondence will be used to establish a final stockpile sampling frequency of 1 sample per 
250, 500, 750, or 1,000 cubic yards or other approved sampling ratio.

the potential for risk to human health and the environment at the receiving Brownfields 
property, and that a record of the acceptance of such soil from the property owner of 
the receiving site is provided to Brownfields.  Please provide additional details below.  
☒ Use as Beneficial Fill off‐site at a non‐Brownfields Property ‐ Please provide

Other comments regarding managing impacted soil in utility trenches:  
Utility trenches (other than those being demolished) are not included in this EMP which covers Early 
Grading and Demolition (Phase 1A‐01/Design Package D‐1) activities. For demolition of utilities, utility 
materials including any sludges accumulated in pipes will be containerized and disposed offsite. 
Sludges will not be allowed to make contact with Site soils. In the event that waste sludges are 
discovered to have leaked from piping being removed during demolition activities or have otherwise 
come in contact with soil, the NCBP will be notified and the procedures outlined in the Contingency 
Plan – Buried Waste Material section of this EMP will be followed. 

PART 2. GROUNDWATER  

1) What is the depth to groundwater at the Brownfields Property? 
The water table is anticipated to be between 10 and 25 feet below ground surface (due to 
topographic changes at the site) under non‐pumping conditions based on historical data reports 
for the DSCA monitoring well network. 

2) Is groundwater known to be contaminated by ☐onsite  ☐offsite   ☒both or ☐unknown 
sources?  Describe source(s):  
As documented in assessment reports and shown in Table 2, groundwater is impacted by 
chlorinated solvents, primarily PCE but also trichloroethene (TCE) and carbon tetrachloride. The 
most recent estimated extent of the groundwater plume, as of August 2021, is included in Figure 

26 
EMP Version 2, January 2021  
4A. Based on the hydrogeologic features, the water quality data, and water table data for the 
property, the Former Domestic Laundry DSCA site is likely a contributing source for a portion of 
the identified groundwater contaminant plume (Area B), and other unknown sources (non‐DSCA 
sources) are contributing to other portions of the groundwater contaminant plume. Exceedances 
of groundwater standards extend beyond what can hydraulically be derived from the known 
release at the Former Domestic Laundry. Portions of the plume could be influenced by other 
former or current surrounding‐area dry‐cleaning facilities, filling stations, or auto repair facilities.  

3) What is the direction of groundwater flow at the Brownfields Property?  
As shown on Figure 4A, groundwater in the northeast (DSCA property) flows south to southeast 
and groundwater in the southwest (non‐DSCA properties) flows east to southeast. Groundwater 
appears to be potentially influenced by a culverted stream running through the Brownfields Site 
beneath Baxter Street and groundwater flows towards this culverted stream prior to flowing to 
the southeast.  

4) Will groundwater likely be encountered during planned redevelopment activities?   
☐Yes    ☒No  
If yes, describe these activities: 
This EMP covers Early Grading and Demolition which is anticipated to reach depths up to 11 feet 
and is not anticipated to encounter groundwater. However, perched groundwater may be 
encountered and will be managed as described in this section and the Soil and Water 
Management Memo (Attachment D). 

Regardless of the answer; in the event that contaminated groundwater is encountered 
during redevelopment activities (even if no is checked above), list activities for contingent 
management of groundwater (e.g., dewatering of groundwater from excavations or 
foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or 
sampling procedures).  
In the event that groundwater is encountered, it will be pumped into an approved frac tank 
(preferably double walled, if available) or other container (such as a 55‐gallon drum for small 
volumes) by the Contractor as approved by the EP and staged within secondary containment 
(double‐wall or berm). As described in the Soil and Water Management Memo (Attachment 
E), water from Area A and B will be managed as listed hazardous waste until characterization 
of containerized waste is conducted by the EP. If concentrations of dry‐cleaning solvents are 
above the North Carolina Administrative Code (NCAC) Title 15A Subchapter 02L.0202 
Standards (2L Standards) or water exhibits a hazardous waste characteristic, the water from 
Area A and B will be disposed at an offsite hazardous waste treatment facility. 

For water which does not exhibit a hazardous waste characteristic (Area C groundwater based 
on existing groundwater data and water from Area A and B that was tested as described above), 
water will be containerized for offsite disposal as non‐hazardous waste, or placed in a settling 
tank as the first step of water treatment. Sampling and analysis will be conducted by the EP as 
needed to characterize the water for disposal purposes based on the requirements of the 
disposal facility. Initial analyses will include VOCs by EPA Method 8260, SVOCs by EPA method 
8270, and RCRA metals by EPA Methods 6020 and 7471. Subsequent analyses will be limited to 
constituents documented to be present at the site including, at a minimum, VOCs and any other 

27 
EMP Version 2, January 2021  
compounds required to manage water by the receiving facility or permitting entity (offsite non‐
hazardous treatment facility, discharge to storm sewer through National Pollutant Discharge 
Elimination System [NPDES] permit, or discharge to sanitary sewer through municipal permit). 

5) Are monitoring wells currently present on the Brownfields Property?.................☒Yes   ☐No    
If yes, are any monitoring wells routinely monitored through DEQ or other 
agencies?..................................................................................................................☐Yes   ☒No  

6) Please check methods to be utilized in the management of known and previously 
unidentified wells.   
☒ Abandonment of site monitoring wells in accordance with all applicable regulations.  It 
is the Brownfields Program’s intent to allow proper abandonment of well(s) as 
specified in the Brownfields Agreement, except if required for active monitoring 
through another section of DEQ or the EPA.   
☐ Location of existing monitoring wells marked 
☐ Existing monitoring wells protected from disturbance  
☒ Newly identified monitoring wells will be marked and protected from further 
disturbance until notification to DEQ Brownfields can be made and approval for 
abandonment is given. 

7) Please provide additional details as needed:   

Please note, disturbance of existing site monitoring wells without approval by DEQ is not 
permissible.  If monitoring wells are damaged and/or destroyed, DEQ may require that the PD 
be responsible for replacement of the well.   

PART 3. SURFACE WATER 
1) Is surface water present at the property?  ☒ Yes ☐ No ☐ Unknown 
2) Attach a map showing the location of surface water at the Brownfields Property. 
Figure 4A shows the existing culverted stream that runs through the Brownfields site beneath 
Baxter Street. As shown in Figure 3, the redevelopment includes relocating this stream to the 
other side of Baxter Street. The surface water is not in direct contact with the surface and is not 
anticipated to be encountered during the Early Grading and Demolition phase of construction 
covered under this EMP.  
3) Is surface water at the property known to be contaminated? ☐ Yes  ☒ No 
4) Will workers or the public be in contact with surface water during planned redevelopment 
activities?    ☐ Yes  ☒ No  
Not during the Early Grading and Demolition phase of construction covered under this EMP. 
Abandonment of monitoring wells in the DSCA monitoring network will be coordinated with the DSCA 
site project manager at NCDEQ.  

28 
EMP Version 2, January 2021  
5) In the event that contaminated surface water is encountered during redevelopment 
activities, or clean surface water enters open excavations, list activities for management of 
such events (e.g. flooding, contaminated surface water run‐off, stormwater impacts): 
Available information indicates that surface water should not be in direct contact with soil and 
groundwater impacts at the site because it is contained within a culvert. At this time, Early 
Grading and Demolition will not include work within the underlying culverted stream area. 
However, demolition may include disconnection of sewer lines or other utilities from the 
building. Water or sludges from utility lines will be containerized and disposed offsite. Soils in 
contact with the sludges will be managed as potentially contaminated material following the 
procedures outlined in the Contingency Plan – Buried Waste Material section of this EMP.  In 
addition, impacted surface water scenarios could occur during a rainfall event during excavation 
activities. If areas of impacted soil are encountered during construction, as needed, they will be 
covered with plastic by the Contractor to prevent direct contact with rain/surface water while 
soil grading activities are occurring. Exposed soils within the portion of Area A with documented 
soil to groundwater PSRG exceedances (Figure 4B) will also be covered with plastic prior to rain 
events. Stockpiles will be managed per Figure 1 of this EMP template and roll‐offs of soils will be 
covered prior to rain events.  

If applicable, water that has contacted impacted soil will be contained on‐site. For water in 
contact with Area A impacted soils, water will be placed into a tanker truck, frac tank, 55‐gallon 
drum, or other storage container by the Contractor as approved by the EP. For water in contact 
with impacted soils outside Area A, water may be containerized as above or may be contained 
using diking, trenching, and/or will be allowed to infiltrate into soils. Water intended for off‐site 
disposal or discharge to a publicly owned treatment works (POTW) will be sampled by the EP for 
laboratory analysis based on the requirements of the disposal facility, as described for 
groundwater in the Soil and Water Management Memo (Attachment D).  

PART 4. SEDIMENT 

1) Are sediment sources present on the property?  ☒ Yes  ☐ No 

2) If yes, is sediment at the property known to be contaminated: ☐ Yes  ☐ No ☒ Unknown 

3) Will workers or the public be in contact with sediment during planned redevelopment 
activities?   ☐ Yes ☒ No 

Not during the Early Grading and Demolition phase of construction covered under this EMP. 

4) Attach a map showing location of known contaminated sediment at the property. 
Figure 4A shows the existing culverted stream that runs through the Brownfields site beneath 
Baxter Street. As shown in Figure 3, the redevelopment includes relocating this stream to the 

29 
EMP Version 2, January 2021  
other side of Baxter Street. The sediment within this culvert is not in direct contact with the 
surface and is not anticipated to be encountered during the Early Grading and Demolition 
phase of construction covered under this EMP.  

5) In the event that contaminated sediment is encountered during redevelopment activities, list 
activities for management of such events (stream bed disturbance): 
Sediment is not expected to be encountered during this Early Grading and Demolition phase of 
construction because the culvert relocation will occur under a subsequent construction phase and 
will be addressed in a subsequent EMP. However, if impacted sediments are encountered, the EP 
will contact the NCBP and protocols for proper characterization and disposition will be 
established. 

PART 5.  SOIL VAPOR 

1) Do concentrations of volatile organic compounds at the Brownfields property exceed the 
following vapor intrusion screening levels (current version) in the following media: 
IHSB Residential Screening Levels: 
Soil Vapor:………..☒ Yes ☐ No  ☐ Unknown 
Groundwater:.….☒ Yes ☐ No ☐ Unknown 
IHSB Industrial/Commercial Screening Levels: 
Soil Vapor:………..☒ Yes ☐ No ☐ Unknown 
Groundwater:…..☒ Yes ☐ No ☐ Unknown 
2) Attach a map showing the locations of soil vapor contaminants that exceed site 
screening levels.  
Table 3 shows analytical results for soil vapor at the site and Figure 4C shows the sample 
locations and estimated extent of impacts above the Residential and 
Industrial/Commercial Screening Levels. Impacts above Industrial/Commercial Screening 
Levels are limited to the former source area. 
3) If applicable, at what depth(s) is soil vapor known to be contaminated?  

4) Will workers encounter contaminated soil vapor during planned redevelopment activities? 

  ☒ Yes  ☐ No ☐ Unknown   
In the event that contaminated soil vapor is encountered during redevelopment activities 
(trenches, manways, basements or other subsurface work,) list activities for management of 
such contact:  
Soil gas analytical data from 5 to 7.5 feet below ground surface has exhibited impacts from PCE, 
methylene chloride, carbon tetrachloride, ethylbenzene, chloroform, and benzene. Impacts are below 
the Industrial/Commercial Screening Levels outside of the Area A source area. 

30 
EMP Version 2, January 2021  
Contaminated soil vapor may be encountered during grading activities. Outside of Area A, 
impacts are below the Industrial/Commercial Screening Levels. Within Area A, care will be taken 
to grade in a manner that allows ventilation by avoiding the excavation of trenches or pits. 
During grading within Area A, an EP will be present to make field observations and field screen 
ambient air to evaluate breathing zone air quality. The level of on‐site EP oversight may decrease 
if initial screening results consistently suggest a lack of impacts. If Site screening indicates 
potential for exposure to impacted soil vapor, safety screening activities such as breathing zone 
monitoring with a calibrated PID (or similar) will be implemented. If screening results indicate the 
need for additional safety measures, the Contractor will implement engineering controls such as 
additional ventilation and wear appropriate personal protective equipment (PPE) for worker 
safety. 

PART 6.  SUB‐SLAB SOIL VAPOR 
1) Do concentrations of volatile organic compounds at the Brownfields property exceed the

2) If data indicate that sub‐slab soil vapor concentrations exceed screening levels, attach a map 
showing the location of these exceedances. 
3) At what depth(s) is sub‐slab soil vapor known to be contaminated? ☐0‐6 inches ☒Other, please 
describe:   
Based on soil vapor data and the extent of the existing groundwater plume, construction will 
proceed under the assumption that sub‐slab vapor from 0 to 6 inches within the extent of soil 
vapor and groundwater impacts is also impacted. However, the majority of the documented soil 
gas impacts are below the Industrial/Commercial Screening Levels. 

4) Will workers encounter contaminated sub‐slab soil vapor during planned redevelopment 
activities? ☒ Yes   ☐ No   ☐ Unknown

EMP Version 2, January 2021  
removing building slabs adjacent to Area A, care will be taken to remove slabs in a manner that 
allows ventilation. During initial slab removal adjacent to Area A, an EP will be present to make 
field observations and field screen ambient air to evaluate breathing zone air quality. The level of 
on‐site EP oversight may decrease if initial screening results consistently suggest a lack of 
impacts. If Site screening indicates potential for exposure to impacted soil vapor, safety 
screening activities such as breathing zone monitoring with a calibrated PID (or similar) will be 
implemented. If screening results indicate the need for additional safety measures, the 
Contractor will implement engineering controls such as additional ventilation and wear 
appropriate PPE for worker safety. 

PART 7. INDOOR AIR 

1) Are indoor air data available for the Brownfields Property? ☐ Yes   ☒ No   ☐ Unknown 
2) Attach a map showing the location(s) where indoor air contaminants exceed site screening levels. 
3) If the structures where indoor air has been documented to exceed risk‐based screening levels will 
not be demolished as part of redevelopment activities, will workers encounter contaminated 
indoor air during planned redevelopment activities? ☐ Yes   ☐ No   ☐ Unknown

Please provide details on the proposed methods of managing the following commonly 
encountered issues during redevelopment of Brownfields Properties. 
Prior to beginning initial grading activities, the EP will attend a pre‐construction kick‐off meeting 
with the PD and site contractors to discuss the DEQ‐approved EMP and describe scenarios when it 
would be appropriate and necessary to notify the EP of the discovery of potentially impacted media 
or unknown subsurface features at the Site.  Available data indicates a low potential to encounter 
conditions beyond those already identified under prior assessment reports.  

The PD recognizes that the existing facilities have emergency generators with base‐tank diesel ASTs 
which will be decommissioned during demolition. These generators with ASTs are self‐contained 
units and, as such, are anticipated to be removed as a unit. Diesel fuels will be pumped into a 
vacuum truck prior to off‐site transport of the units. An EP will be present during unit removal and 
will observe the concrete beneath the units once removed. If there is evidence of a fuel release, the 
NCDEQ Non‐UST Petroleum Release guidance will be followed (Non‐UST Program | NC DEQ). 

Underground Storage Tanks:  
Available information indicates that it is unlikely for USTs to be present at the site. In the unlikely 
event that a UST is identified, UST closure and corrective action will be followed per applicable 
NCDEQ UST Section regulations and guidance. This may include the use of a mobile laboratory with 
Ultra‐Violet Fluorescent (UVF) capabilities to help determine the extent of impacts in the field. 
Confirmatory soil samples will be collected from four sidewalls and at least one base sample 
(depending on size) of the final excavation. Confirmation analysis will include VOCs by EPA Method 
8260, SVOCs by EPA Method 8270, RCRA Metals by EPA Methods 6020 and 7471, and Hexavalent 
Chromium by EPA Method 7199, as applicable, to meet NCBP requirements. Additional analysis may 
include those listed in UST Section Guidance, Table 3. Approved Methods for Soil Analyses at 
Petroleum UST Closures and Over‐Excavation and at Site Checks are listed here 
(https://files.nc.gov/ncdeq/Waste%20Management/DWM/UST/Corrective%20Action/ACA%20table
s%20Chng3%20112013.pdf).   

Sub‐Grade Feature/Pit: 
Because of the historical use of the Brownfields Property, it is unlikely for sub‐grade features/pits to 
be encountered beyond what has already been identified under previous assessment reports. In the 
event that such features are identified, they will be handled under Guidelines for Assessment and 
Cleanup of Contaminated Sites (NCDEQ IHSB, January 2020) located here 
(https://files.nc.gov/ncdeq/Waste%20Management/DWM/SF/IHS/guidance/IHSB_RemediationGuid
ance012720.pdf) 

Buried Waste Material – Note that if buried waste, non‐native fill, or any obviously filled materials 
is encountered, the DEQ Brownfields Program must be notified to determine if investigation of 

34 
EMP Version 2, January 2021  
landfill gases is required: 
The NCBP will be notified in the event that buried wastes are encountered other than for the 
conditions previously described in this EMP. Work will be stopped and plans will be conducted to 
evaluate the waste if the EP believes that the characteristics of the material is inconsistent with data 
from previous assessment reports. 

Re‐Use of Impacted Soils On‐Site: 
Grossly impacted soils will not be re‐used on‐site. Per the procedures identified in this EMP, the EP 
will screen soils to evaluate the presence of impacts, if any, and appropriate re‐use scenarios. 

If unknown, impacted soil is identified on‐site, management on‐site 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 on‐site.  

If other potential contingency plans are pertinent, please provide other details or scenarios as 
needed below:

SGSLs from North Carolina Department of Environmental Quality (NCDEQ) Residential and Industrial Vapor Intrusion Screening Levels from January 2022.2. SGSL assumes a Target Cancer Risk (TCR) of 1.0E-06 and a Target Hazard Quotient (THQ) of 0.2.3. Only constituents that were detected above the laboratory Method Detection limit (MDL) in at least one soil gas sample are included in this table, along with constituents where the Reporting Limit (RL) exceeded a SGSL.4. Black text concentrations are detected above the laboratory RL.5. Grey highlighted values indicate that the MDL is greater than a SGSL.6. Concentrations highlighted in yellow indicate exceedances of the Residential SGSL.7. Concentrations highlighted in orange indicate exceedances of the Industrial SGSL.8. µg/m3 indicates micrograms of analyte per cubic meter of air.9. ft bgs indicates feet below ground surface.10. < indicates analyte not detected above the RL indicated.11. NC indicates there is no applicable SGSL.12. (DUP) indicates duplicate sample results.13.

Subject: Soil and Water Management, Former Domestic Laundry Brownfields Property
(BF# 25032-21-060), 801 S. McDowell St., Charlotte, NC

INTRODUCTION AND BACKGROUND
The Charlotte-Mecklenburg Hospital Authority dba Atrium Health (Atrium) is planning to
redevelop properties located near the northeast corner of the intersection of South McDowell and
East Morehead Streets in Charlotte, North Carolina (“Site” or “Brownfields Assemblage”) under
the Brownfields Program. One of the properties included in the Brownfields Assemblage is the
Former Domestic Laundry property located at 801 South McDowell Street which is part of the
North Carolina Department of Environmental Quality (NCDEQ) Dry-Cleaning Solvent Cleanup
Act (DSCA) Program under DSCA ID# DC600012.
On 30 November 2021, a call was held between representatives of the NCDEQ (Brownfields
Program [NCBP], DSCA Program, and Hazardous Waste Section), Robinson Bradshaw (Atrium’s
private counsel), Kimley-Horn and Associates, Inc. (Atrium’s civil engineering firm) and
Geosyntec Consultants of NC, P.C. (Atrium’s environmental consulting firm) to discuss soil and
water management during redevelopment of the Brownfields Assemblage. The purpose of this
memorandum is to provide NCDEQ with a summary of our proposed programmatic approach to
managing water and soil during construction. This approach will be referenced in the Site’s NCBP-
approved Environmental Management Plan (EMP) for implementation during construction. The
approach presented herein identifies regulations and policies that may apply to the management of
water and soil impacted by the known DSCA release incident or other sources of contamination

present at the Site. After review of this memorandum by NCDEQ’s Brownfields Program,
Hazardous Waste Section, and DSCA Program, we respectfully request written concurrence from
NCDEQ on the proposed water and soil management practices prior to incorporation in the Site’s
EMP. It is understood that communications regarding implementation of the EMP, including
sampling plans (when needed) for in situ or ex situ waste characterizations will be directed through
the NCDEQ Brownfields Program project manager.
Within this document, soils will be defined as solid materials which are dry enough that free liquid
does not separate from the materials. If free liquid separates from the material, it will be defined
as mud. A slurry will be defined as a combination of water into solid material that results from
mixing of materials. In the context of in-situ sampling, soil above the historically high water table
(based on historical monitoring well gauging data) are considered unsaturated soils while soil
below the historically high water table are considered saturated soils impacted by the underlying
groundwater plume (as applicable).
WATER MANAGEMENT
It is our understanding that NCDEQ regulates extracted groundwater which contains used dry-
cleaning solvents from known releases as a listed hazardous waste, as defined in 40 Code of
Federal Regulations (CFR) 261 Subpart D and adopted by reference in 15A North Carolina
Administrative Code (NCAC) 13A .0106. Groundwater contamination (detections of constituents
above the North Carolina Administrative Code (NCAC) Title 15A Subchapter 02L.0202 Standards
[2L Standards]) have been identified on the Brownfields Property. Based on the hydrogeologic
features, the water quality data, and water table data for the property, it is apparent that the Former
Domestic Laundry is a contributing source for a portion of the identified groundwater contaminant
plume, and other unknown sources (non-DSCA sources) are contributing to other portions of the
groundwater contaminant plume. Exceedances of the 2L Standards extend beyond what can
hydraulically be derived from the known release at the Former Domestic Laundry. Portions of the
plume could be influenced by other former or current surrounding-area dry-cleaning facilities,
filling stations, or auto repair facilities. There is insufficient data to identify which of these sources
(if any) specifically contributed to the groundwater plume. Figure 1 depicts some of the potential
sources which have been identified through our assessment; the approximated groundwater plume
based on August 2021 data; and the inferred potentiometric surface based on August 2021 depth
to water measurements which is similar to historic potentiometric surfaces published by the DSCA
Program. As shown in the figure, groundwater in the northeast (DSCA property) and southwest
(non-DSCA properties) appears to be potentially influenced by a culverted stream running through
the Brownfields Assemblage beneath Baxter Street, prior to flowing to the southeast. As such, the
stream may act as a hydraulic divide. On this basis, we have utilized the stream as a dividing
feature between known release areas (areas northeast of the stream) and unknown release areas
26 April 2022
Page 3

GC7466/CAR210229

(areas southwest of the stream) as shown in Figure 2. Water generated during construction as a
result of dewatering or decanting water from settled soil or muds will similarly be managed based
on the origin relative the location from which they came from (i.e., either to the northeast or
southwest of the stream).
Based on this divide, the Site has been divided into the following areas for groundwater and
decanted water management, as outlined in a flow chart on Figure 3:
 DSCA area groundwater and decanted water from Areas A and B on Figure 2 will be
containerized and managed as listed hazardous waste unless analytical results of
containerized waste characterization show that concentrations of dry-cleaning solvents are
below the 2L Standard. If the test results are below 2L Standards, the water can potentially
be managed using one or more of the three water management alternatives provided in
Figure 3.
 Non-DSCA area groundwater and decanted water from Area C on Figure 2 will be
containerized and analyzed per one or more of the requirements for the three water
management alternatives identified in Figure 3.
For small-scale investigations or small volumes of decanted water, groundwater will be
containerized in 55-gallon drums and drums will be staged on drum spill pallets as secondary
containment. For larger volumes of groundwater generation such as dewatering and foundation
installation, groundwater will be containerized in frac tanks that are preferably double walled
(based on availability) or single walled. Additional secondary containment will be utilized for
single walled tanks which may include the use of a separate secondary containment structure
and/or use of plastic lined earth berms. If the containerized water is considered hazardous waste,
Resource Conservation and Recovery Act (RCRA) requirements will be followed. No treatment
of the groundwater is planned for hazardous waste. If treatment is considered for hazardous waste,
RCRA Land Disposal Restrictions (LDR) requirements will be addressed.
Containerized groundwater will be characterized by collecting samples (according to sampling
methodology provided in the EMP or a sampling plan) from each container into laboratory
supplied bottleware and submitting on ice under chain of custody to a North Carolina-certified
laboratory. Initial analyses will include VOCs by United States Environmental Protection Agency
(USEPA) Method 8260, semi-volatile organic compounds (SVOCs) by USEPA Method 8270, and
RCRA Metals by USEPA Methods 6020 and 7471. Subsequent analyses will be limited to
constituents documented to be present at the Site including, at minimum, USEPA Method 8260
for VOCs and any other compounds required to manage water by the receiving facility or
permitting entity under the three options provided in Figure 3 dependent on water origin.

SOIL AND MUD MANAGEMENT
For soils impacted with a listed hazardous waste (the groundwater), NCDEQ’s “Contained-in”
Policy for Soil Contaminated with Listed Hazardous Waste (NCDEQ, 2016) can be applied to
manage the materials. Soils within the area northeast of the stream and below the historic high
water table within the area of the estimated groundwater plume as well as soils from the initial
source area (Figure 2), may have been in contact with listed hazardous waste and consequently
may be managed under the “contained-in” policy. In general accordance with the policy, soils will
be containerized and analyzed using TCLP USEPA Method 1311. Analysis will be limited to
compounds that have historically been detected in soil and groundwater at the Site and to
parameters requested by the selected permitted disposal facility and/or as required by permit. A
characterization analyte list and corresponding list of laboratory methods will be included in work
plans for NCDEQ review and approval prior to sampling. Results will be compared to the
Maximum Concentrations of Contaminants leachate criteria for the Toxicity Characteristic
compounds listed in Table 1 of Title 40 CFR Part 261.24 to evaluate if soils meet the minimum
requirements for “contained-out”.
The Site has been divided into the following areas for soil and decanted water management, as
outlined in a flow chart on Figure 4:
 DSCA area soils and DSCA area mud (from Area A and below the water table in Area B
from Figure 2): will be managed under the contained-out rule by being containerized in
Hazmat compliant roll-offs with plastic liners and gasketed doors. In -situ characterizations
may also potentially be conducted to characterize soils in-place to allow soils to be directly
loaded into trucks. In-situ characterization of DSCA area soils would be described in an
NCDEQ-approved work plan prior to conducting sampling. If containerized, moisture in
the muds may separate from the soil as water. In addition, during redevelopment, methods
such as micropile installation sometimes use fluids such as water or drilling fluid
(slurry/mud) or polymer flush (using polymers which do not contain solvents or other
compounds which would degrade groundwater quality, as will be documented through
Material Safety Data Sheets). Derived materials from this form of drilling may need to be
managed using a silt bag within the lined and gasketed roll-offs to separate the fluids. If
fluid accumulation occurs from mud containerization, the water will be decanted into
separate containers and handled as described in the groundwater management section,
dependent on the soil origin location and whether it was in an area where soils made contact
with the DSCA portion of the groundwater plume (i.e., northeast of the stream). Decanting
of water will be considered exempt from treatment because the containers will only be
opened to add or remove waste. Decanting methods will be described in the EMP.
26 April 2022

GC7466/CAR210229

Containerized soils will be characterized by collecting a composite soil sample (consisting
of 5 to 6 soil samples from each roll-off sent to the lab to be composited as well as a grab
sample for the VOC analysis) for totals and TCLP analyses as described below. The TCLP
sample will be placed on hold and only analyzed if totals analysis is above the Municipal
Solid Waste Landfill (MSWLF) criteria. Additional analyses may be required to meet
permit requirements for the selected disposal facility. Results of the TCLP analysis will be
compared to the Maximum Concentrations of Contaminants for the Toxicity Characteristic
compounds listed in Table 1 of Title 40 CFR Part 261.24.
 Non-DSCA area muds (from below the water table in Area C of Figure 2): As needed and
following sampling protocols of the NCDEQ-approved EMP, muds will be pre-
characterized through collection of in-situ aquifer matrix samples which would be
representative of saturated materials if beneath the historically high water table.
Alternatively, groundwater sampling results representative of the work area, can be used
to characterize muds for management purposes. As previously discussed, sampling
approaches will be presented in a work plan for regulatory review and approval. Slurries
and muds will be filtered with a silt bag in Hazmat compliant roll-offs and/or other means
to remove sediment as many disposal facilities do not accept mud mixtures. Muds will be
sampled to meet requirements for the selected soil management options in Figure 4 as
described below. Samples will be sent to the lab for compositing 5 to 6 aliquots along with
a grab VOC sample. As applicable, results of TCLP analysis for muds to be transported
off-site will be compared to the Maximum Concentrations of Contaminants for the Toxicity
Characteristic compounds listed in Table 1 of Title 40 CFR Part 261.24.
 Non-DSCA area soils (from above the water table in Areas B and C of Figure 2): As
needed and following sampling protocols of the NCDEQ-approved EMP, soils will be pre-
characterized through collection of in-situ soil samples which would be representative of
unsaturated materials if above the historically high water table. Soils may be stockpiled or
live-loaded. Soils will be sampled to meet requirements for the selected soil management
options in Figure 4 as described below. Samples will be sent to the lab for compositing 5
to 6 aliquots along with a grab VOC sample. As applicable, results of TCLP analysis for
soils to be transported off-site will be compared to the Maximum Concentrations of
Contaminants for the Toxicity Characteristic compounds listed in Table 1 of Title 40 CFR
Part 261.24. Results of totals analyses for soils to be re-used on-site will be input into the
North Carolina Risk Calculator and evaluated for potential on-site re-use based on
anticipated potential receptors.
Soil and mud samples will be collected into laboratory supplied bottleware and submitted on ice
under chain of custody to a North Carolina-certified laboratory for analysis. Sample collection

methods will comply with the most current version of the USEPA Region IV Laboratory Services
and Applied Sciences Division (LSASD) Quality System and Technical Procedures for Field
Branches guidance. The samples will be processed using the TCLP USEPA Method 1311 and
VOCs will be analyzed by USEPA Method 8260, SVOCs by USEPA Method 8270, RCRA Metals
by USEPA Methods 6020 and 7471, and hexavalent chromium by USEPA Method 7199 for the
selected list of TCLP parameters as well as other potential compounds that may be needed for the
selected soil management options. Select samples which are deemed to be geotechnically suitable
for re-use may also be sampled for total VOCs by USEPA Method 8260, semi-volatile organic
compounds by USEPA Method 8270, RCRA Metals by USEPA Methods 6020 and 7471, and
hexavalent chromium by USEPA Method 7199.

HAZARDOUS MATERIALS MANAGEMENT
Groundwater, soils, and muds identified as hazardous waste through the procedure above will be
managed under a unique EPA ID number for the property and generator (The Charlotte-
