1.0 Introduction

Hart & Hickman, PC (H&H) has prepared this Vapor Intrusion Assessment Report on behalf of
SPWF-Continental Warehouse, LLC (Prospective Developer or PD) for the REEP-LRC(RN)
Brownfields property (Brownfields Project No. 24001-20-060). The Brownfields property is
located at 1900 Continental Boulevard in Charlotte, Mecklenburg County, North Carolina (Site)
and consists of two parcels of land that total approximately 85.2 acres. Specifically, the Site is
located at 1900 Continental Boulevard (Mecklenburg County Parcel Identification Number [PIN]
20308301) and a parcel east of Interstate I-485 with no established address (PIN 20302139). The
Site is developed with an approximately 1,370,000 square foot (sq ft) warehouse building located
to the west of Interstate I-485. The Site building is currently used for warehousing,
manufacturing, and distribution. Site PIN 20302139 is currently vacant wooded land. A Site
location map is provided as Figure 1.

The Brownfields property and surrounding area were formerly occupied by the United States
Navy from approximately 1949 through 1967. Former use of the Site as a Naval Ammunitions
Depot (NAD) included operations consisting of numerous buildings surrounded by protective
soil berms based on a 1950 aerial photograph and a 1950 map of the former NAD. Following
NAD operations, the Site was occupied by Continental Tire and used for tire manufacturing from
1967 through 2013.

The Site received updated eligibility (following execution of the Brownfields Agreement for the
REEP-LRC Brownfields property [Brownfields Project No. 17047-13-060]) into the North
Carolina Department of Environmental Quality (DEQ) Brownfields Program via a Letter of
Eligibility dated February 27, 2020. Redevelopment activities for the Brownfields property have
been conducted in accordance with an Environmental Management Plan (EMP) approved by

DEQ on June 3, 2021. These activities have included the installation of a pre-fabricated fire
pump house in the southwestern portion of the Site, renovations to the northwestern portion of
the existing warehouse building, installation of a new road that circulates existing structures and
will allow access for future development on the adjacent REEP-LRC Brownfields property, and
temporary off-Site stockpiling of soil on the REEP-LRC Brownfields property (PIN 20308305)
for later beneficial reuse. The Site and surrounding area are shown on Figure 2.

The existing warehouse building located on PIN 20308301 is divided into the following tenant
spaces, which are identified on Figure 2:

• Suites A, G, and H – Spirit Halloween
• Suite B – Professional Builders Supply
• Suite C – Harris Tire
• Suite D – Darnell
• Suites E and F – Synders Lance
• Suite I – United States Postal Service (USPS)
• Suite J – Siemens/ Deufol Charlotte, LLC
• Suite K – SnapAV

On September 24, 2020, H&H, the PD, and the PD’s legal counsel participated in a conference
call with DEQ Brownfields personnel to discuss Site history, areas of potential environmental
concern, proposed redevelopment plans, potential data gaps, and the scope of Brownfields
assessment activities needed to address the data gaps. To address DEQ’s request for additional
assessment on Site PINs 20308301 and 20302139, H&H submitted an Additional Brownfields
Assessment Work Plan (Work Plan) dated November 19, 2020, and revised on February 4, 2021.
The Work Plan was approved by DEQ Brownfields in an email dated February 19, 2021.

As part of property transaction due diligence conducted on PIN 20308301 and Brownfields
assessment activities conducted in November 2019 and March 2021 (post-approval of the
aforementioned Work Plan), respectively, H&H performed sampling activities to assess potential

structural vapor intrusion into the existing warehouse building. Results of sub-slab vapor
assessment activities indicate that calculated cumulative risk values for the soil gas to indoor air
vapor intrusion pathway were within acceptable risk levels for potential carcinogenic risks (1 x
10-4) and non-carcinogenic risks (1.0).

Based on the presence of trichloroethylene (TCE) in sub-slab vapor samples collected during the
2019 and 2021 sampling events, DEQ Brownfields requested additional vapor intrusion
assessment for the warehouse building in an email dated June 9, 2022. In the email, DEQ stated
that the February 2021 Work Plan and procedures provided in subsequent email correspondence
from H&H could be used to execute the requested scope of work.

In accordance with the Work Plan and approved scope of work, vapor intrusion assessment
activities were conducted by H&H within the existing warehouse building located on PIN
20308301. A summary of historical assessment activities conducted on PIN 20308301 and
recently completed vapor intrusion assessment activities for PIN 20308301 are provided in the
following sections.

2.0 Historical Use Information – PIN 20308301

Multiple phases of environmental assessments have been conducted at the Brownfields property
since 2007. The assessments were conducted under the purview of the DEQ Underground
Storage Tank (UST) Section, Inactive Hazardous Sites Branch (IHSB), and the Brownfields
Program. Known releases associated with PIN 20308301 include the former Wash Rack area
(UST Section No Further Action status in June 2010), the former Boiler Day Tanks area (UST
Section No Further Action status in June 2010), the former Naphtha UST area (UST Section
Conditional No Further Action status and Notice of Residual Petroleum filed in 2003), the
former Rail Off-Loading Area (UST Section Conditional No Further Action status in January
2020), and the former Buffing Dust Shed (active IHSB incident). H&H understands that
Continental Tire is identified by DEQ as the responsible party for the active Buffing Dust Shed
IHSB incident, and that ongoing off-Site vapor intrusion assessment activities are currently
underway.

Historical soil assessment activities completed on PIN 20308301 in 2009 to assess conditions
associated with the former Buffing Dust Shed indicate low levels of several volatile organic
compounds (VOCs) were detected in surficial soil samples at concentrations above laboratory
detection limits, but below the DEQ Industrial/Commercial Preliminary Soil Remediation Goals
(PSRGs). In addition, low levels of several metals were detected at concentrations above the
laboratory method detection limits, but aside from arsenic (up to 5.5 milligrams per kilogram
[mg/kg]), no metals were detected at concentrations above the DEQ Industrial/Commercial
PSRGs. Concentrations of arsenic and other metals are consistent with published background
ranges in the Site region.

Historical groundwater assessment activities conducted on PIN 20308301 dating back to 2009
have identified the presence of multiple compounds at concentrations above the DEQ 15A North
Carolina Administrative Code (NCAC) 02L .0202 Groundwater Quality Standards (2L
Standards). Compounds detected above 2L Standards include, but are not limited to, iron and
manganese, polycyclic aromatic hydrocarbons (PAHs), and VOCs benzene, 1,1-dichloroethane,
1,2-dichloroethane, carbon tetrachloride, tetrachloroethylene (PCE), trichloroethylene (TCE),

and vinyl chloride.

As part of property transaction due diligence conducted on PIN 20308301 in November 2019,
H&H performed sampling activities to assess potential structural vapor intrusion into the existing
warehouse building. Specifically, the vapor intrusion assessment activities included installation
and sampling of nine sub-slab vapor points in the Deufol tenant space (SS-6 through SS-9) and a
vacant tenant space (SS-3 through SS-5) due to their proximity to documented soil and
groundwater impacts associated with the aforementioned UST and IHSB incidents. Two sub-
slab vapor points (SS-1 and SS-2) were also installed in the northwestern portion of the
warehouse building where former tire sealant operations were conducted.

The vapor intrusion assessment activities were conducted in accordance with DEQ Division of
Waste Management (DWM) Vapor Intrusion Guidance (VI Guidance) dated March 2018.
Laboratory analytical results indicated that low levels of VOCs were detected above laboratory
method detection limits in each sub-slab vapor sample. Of the compounds detected, 1,1-
dichloroethane was detected at a concentration that exceeds the January 2021 Non-Residential
Sub-Slab and Exterior Soil Gas Screening Level (SGSL) of 770 micrograms per cubic meter
(µg/mPP
3
PP) in sub-slab vapor sample SS-9 (2,200 µg/mPP
3
PP) in the administrative office area. No other
compounds were detected above Non-Residential SGSLs. In addition, DEQ risk calculator
results indicated calculated cumulative risks for a non-residential worker are within the
acceptable carcinogenic risk of less than 1 x 10PP
-4
PP and less than a hazard index of 1.

In March 2021, three additional sub-slab vapor samples were installed and sampled in the
loading dock area of the Deufol tenant space (SS-10 through SS-12) to further evaluate the
potential for structural vapor intrusion into the warehouse building on PIN 20308301 as
requested by DEQ Brownfields. Laboratory analytical results indicated that low levels of VOCs
were detected above laboratory method detection limits in the sub-slab vapor samples but below
Non-Residential SGSLs. In addition, 1,1-dichloroethane, a compound that was previously
detected at a concentration above the Non-Residential SGSL, was not detected above laboratory
method detection limits during the March 2021 sampling event. H&H calculated cumulative
risks using the highest concentrations of compounds detected in any sub-slab vapor sample
6
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Somerset Properties (SSP)/Continental Tire (SSP-001)/Brownfields Assessment/Additional VI Assessment/Final Report/VI Assessment Report_REEP-LRC(RN).doc
collected during the November 2019 and/or March 2021 sampling events to check a hypothetical
worst-case scenario. Results of sub-slab vapor assessment activities indicated that calculated
cumulative risk values for the soil gas to indoor air vapor intrusion pathway were within the
acceptable carcinogenic risk of less than 1 x 10PP
-4
PP and less than a hazard index of 1.

H&H further evaluated the potential for vapor intrusion utilizing groundwater data from
monitoring wells installed under or within 100 ft of the Site building. Based on comparison of
groundwater analytical data to the February 2018 DEQ Non-Residential Ground Water
Screening Levels (GWSLs), no exceedances were identified except for a concentration of
cyclohexane (2,000 micrograms per liter [µg/L]) detected in MW002 in March 2015. The
cyclohexane concentration was above its DWM Non-Residential GWSL of 860 µg/L. However,
cyclohexane was not detected above laboratory reporting limits in any of the sub-slab vapor
samples. As such, cyclohexane in groundwater does not appear to pose a vapor intrusion risk.

2.0 Sub-Slab Vapor Assessment Activities

Between July 19 and 20, 2022, H&H collected 10 sub-slab vapor samples (SS-13 through SS-22)
from several tenant spaces to further evaluate the potential for structural vapor intrusion into
tenant spaces associated with the 1900 Continental Building (PIN 20308301). The sub-slab
vapor sample locations were collected in combination with co-located indoor air samples (see
Section 3.0 for indoor air assessment activities). The sub-slab vapor sample locations (denoted
by SS nomenclature) and indoor air sample locations (denoted by IAS nomenclature) are shown
on Figure 3. Details of the sub-slab vapor assessment activities and results are provided in the
following sections.

2.1 Sub-Slab Vapor Sampling Methodology

The sub-slab vapor monitoring points were installed by utilizing a hammer drill and
1½-inch diameter drill bit to advance a pilot hole into the concrete slab to a depth of
approximately 1¾ inches below the surface. A drill guide was then placed in the pilot hole, and
a 5/8-inch diameter drill bit was utilized to advance the boring through the concrete slab.
Following concrete borehole advancement, loose concrete cuttings were removed from the
boring using a bottlebrush and vacuum with a high efficiency particulate air (HEPA) filter. A
Cox-Colvin Vapor Pin™ (vapor pin) assembly (brass sampling point and silicone sleeve) was
seated in the borehole using an installation/extraction tool and hammer. Once the vapor pin
assembly was secured in the pilot hole, ¼-inch diameter TeflonPP
®
PP sample tubing was attached to
the vapor pin assembly sample port barb. Prior to sampling, sub-slab vapor monitoring points
were allowed to equilibrate for at least two hours following installation.

As part of sub-slab vapor sample collections procedures, “shut-in” tests and leak checks were
performed at each sub-slab vapor monitoring point. The purpose of the shut-in test and helium
leak check is to ensure that short circuiting with ambient air does not occur during sampling. A
description of the shut-in test and helium leak testing procedures is provided below.

The shut-in test was conducted by connecting an in-line airflow controller with a vacuum gauge
to a laboratory supplied batch-certified 1-liter stainless steel SummaPP
®
PP canister and sealing the
8
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Somerset Properties (SSP)/Continental Tire (SSP-001)/Brownfields Assessment/Additional VI Assessment/Final Report/VI Assessment Report_REEP-LRC(RN).doc
flow regulator with a laboratory provided brass nut and ferrule assembly to form an air-tight seal.
The airflow regulator was pre-set by the laboratory to regulate the sub-slab vapor intake rate to
approximately 200 milliliters per minute. Once the sampling train was “closed”, the sample
valve on the SummaPP
®
PP canister was opened and the reading on the vacuum gauge was recorded.
The SummaPP
®
PP canister sample valve was then closed, and the vacuum gauge was observed to
ensure no vacuum loss occurs. Because the vacuum readings remained the same before and after
closure of the canister sample valve, the shut-in tests were considered successful for each sub-
slab vapor point.

Following successful shut-in tests, leak checks were conducted by constructing a shroud around
the sample train at each sampling point and flooding the air with helium gas. Helium
concentrations inside the shroud were measured using a calibrated helium gas detector and
maintained at concentrations of approximately 10% to 20% for the duration of the leak check.
Using a syringe and three-way valve, a helium sample was collected from the TeflonPP
®
PP sample
tubing outside the shroud and into a Tedlar bag. The helium sample was analyzed using the
helium gas detector to ensure that helium concentrations were less than 10% of the helium
concentrations measure within the shroud. All of the sub-slab vapor monitoring points passed
the leak check.

Following a successful leak check, the intake valve on the SummaPP
®
PP canister was fully opened to
begin collection of the sub-slab vapor sample. Vacuum readings on the SummaPP
®
PP canister were
recorded prior to and following the sampling period to ensure adequate sample volume was
collected. Per laboratory standard operating procedures, a vacuum of between approximately
three and seven inches of mercury was maintained on the sample canisters until the conclusion of
the sampling event. Laboratory provided vacuum gauges used for collection of field
measurements are intended for qualitative field use. As such, field measured pre- and post-
sampling vacuum readings are not expected to impact laboratory analytical results based on other
considerations such as sub-slab vapor sampling procedures (i.e., shut-in tests and leak checks)
and post-sampling canister pressures measured by the laboratory. Therefore, H&H concludes
that field and laboratory data generally meet project objectives and are usable for the intended
purpose.

After sample collection, the SummaPP
®
PP canister sample valves were closed prior to disassembly of
the sampling train. The SummaPP
®
PP canisters were then placed in laboratory supplied shipping
containers, properly labeled, and shipped under standard chain-of-custody protocols to Con-test
for analysis of VOCs by EPA Method TO-15. For quality assurance/quality control (QA/QC)
purposes, a duplicate sub-slab vapor sample (SS-DUP) was collected from sub-slab vapor
monitoring point SS-21. Upon receipt of the samples, the laboratory recorded the final received
vacuum pressure for each Summa canister. The initial, post-sampling, and lab receipt canister
vacuum pressures are indicated on the sub-slab vapor QA/QC field forms in Appendix A and in
the laboratory analytical reports included in Appendix B.

Upon completion of the final sampling event, the sub-slab vapor sampling point locations were
estimated in the field using known benchmarks (i.e., walls, doors, etc.) and then abandoned to
match surrounding surface conditions.

2.2 Sub-Slab Vapor Sampling Analytical Results

A tabular summary of sub-slab vapor sample analytical results is presented in Table 1, and the
laboratory analytical reports and chain of custody records are provided in Appendix B. Sub-slab
vapor sample analytical results were compared to the July 2022 DEQ Non-Residential Sub-Slab
and Exterior Soil Gas Screening Levels (SGSLs).

Laboratory analytical results indicated that low levels of VOCs were detected above laboratory
method detection limits in each sub-slab vapor sample. Of the compounds detected, 1,1-
dichloroethane was detected at a concentration above the Non-Residential SGSL of 770
micrograms per cubic meter (µg/m3) in sub-slab vapor sample SS-19 (3,700 µg/m3) in the
Siemens/Deufol tenant space (Suite J). Additionally, TCE was detected at a concentration of
1,200 µg/m3 in sub-slab vapor sample SS-21 (and associated duplicate sample [SS-DUP]) in the
USPS tenant space, which is above the Non-Residential SGSL. TCE was not detected above the
Non-Residential SGSL in any other sub-slab vapor sample collected in July 2022. No other
compounds were detected above Non-Residential SGSLs.

2.3 DEQ DWM Risk Calculations
The DEQ DWM SGSLs are conservative and based on a lifetime incremental cancer risk (LICR)
for potential carcinogenic risks of 1 x 10-6 and a non-carcinogenic hazard quotient (HQ) of 0.2
for potential non-carcinogenic risks. The DEQ acceptable risk level for potential carcinogenic
risks is 1 x 10-4 or less and the acceptable level for non-carcinogenic risks is a hazard index (HI)
less than 1.0.

H&H utilized the July 2022 DEQ risk calculator assuming a non-residential land use scenario
(based on the current Site use) to evaluate calculated cumulative risks for the soil gas (i.e., sub-
slab vapor) to indoor air vapor intrusion pathway in the tenant spaces evaluated. H&H initially
calculated cumulative risk using the highest concentrations of compounds detected in any sub-
slab vapor samples collected for each tenant space to check a hypothetical worst-case scenario
(1). In addition, H&H calculated cumulative risk using the highest concentrations of compounds
detected in any sub-slab vapor samples sans SS-21 (due to TCE) to check a hypothetical worst-
case scenario (2) for all tenant spaces excluding USPS. Results of the risk calculations are
summarized below and included in Appendix C.

Sub-Slab Vapor
Sample Location
Non-Residential Worker
Carcinogenic Risk Hazard Index
Worst-Case Scenario 1
(with SS-21) 1.0 x 10-5 1.5
Worst-Case Scenario 2
(without SS-21) 6.5 x 10-6 0.13
Value in bold exceeds acceptable risk levels.

As shown in the table above, the results of the calculated cumulative risks for a non-residential
worker exceed acceptable levels (calculated cumulative carcinogenic risks below 1 x 10-4 and HI
>1.0) under Worst-Case Scenario 1. Calculated cumulative risks for a non-residential worker
under Worst-Case Scenario 2 are within the acceptable carcinogenic risk of less than 1 x 10-4 and
less than a hazard index of 1.0.

After further review of the worst-case scenario risk calculations, the driver of the cumulative HI

is TCE with an individual HI of 1.4. As discussed in Section 3.3, co-located indoor air samples
were collected to further evaluate the attenuation factor of the concrete slab within the Site
building and the potential vapor intrusion pathway.

12
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Somerset Properties (SSP)/Continental Tire (SSP-001)/Brownfields Assessment/Additional VI Assessment/Final Report/VI Assessment Report_REEP-LRC(RN).doc
3.0 Indoor Air Assessment Activities

On July 18, 2022, H&H collected 10 indoor air samples (IAS-1 through IA-10) from tenant
spaces within the Site building. The indoor air sample locations (denoted by IAS nomenclature)
were co-located with sub-slab vapor monitoring points (denoted by SS nomenclature), as shown
on Figure 3. Details of the indoor air assessment activities and results are provided in the
following sections.

3.1 Indoor Air Sampling Methodology

Prior to indoor air sample collection, H&H conducted a survey within each tenant space
evaluated to identify materials within the space that could potentially influence indoor air testing.
No obvious chemicals of concern were identified. The indoor air survey forms for each tenant
space are provided in Appendix D.

Indoor air samples were collected with the windows and doors of the tenant spaces closed and
ingress and egress activities minimized to the extent practical. Bay doors were intermittently
opened during indoor air sampling in the Professional Builder’s Supply (Suite B) and Snap AV
(Suite K) while briefly loading and unloading of trucks was performed. The samples were
collected while the HVAC systems were running normally in each of the tenant spaces. The
indoor air samples were collected using individually-certified 6-liter stainless steel SummaPP
®PP
canisters connected to in-line flow controllers with a vacuum gauge. The flow controllers were
set so that the samples were collected over an approximate 8-hour period. A 3-foot-long
sampling cane was connected to the flow controller so that the sample intake point was
positioned approximately 5 ft above grade (typical breathing zone height) when the sample
canister is set on its base.

Exterior wind speed and direction, indoor and outdoor temperature, and indoor/outdoor air
differential pressure were measured near the start, middle, and end of the sampling period. At
the end of the 8-hour sample period, the sample canister’s valves were closed to stop sample
collection. An Indoor Air Sampling Form which includes field measurements of temperature,
differential pressure, wind direction, and wind speed is included in Appendix A.

Prior to and after the indoor air samples were collected, vacuum in the canisters was measured
using the laboratory-supplied vacuum gauge and recorded on the chain-of-custody by sampling
personnel. The sample canisters were then labeled and shipped under standard chain-of-custody
protocols to Con-test for analysis of select VOCs by EPA Method TO-15. For quality control
purposes, one duplicate indoor air sample (IAS-DUP) was collected from the IAS-5 sample
location and submitted for the same analysis.

3.2 Indoor Air Sampling Analytical Results
Results of indoor air analysis are summarized in Table 2. The laboratory analytical report and
chain of custody record are provided in Appendix B. Indoor air analytical results were compared
to the July 2022 DEQ Non-Residential Indoor Air Screening Levels (IASLs) which are based on
a LICR for potential carcinogenic risks of 1 x 10-6 and a non-carcinogenic HQ of 0.2.

Laboratory analytical results indicated that low levels of VOCs were detected above laboratory
method detection limits in each indoor air sample. Of the compounds detected, ethylbenzene and
naphthalene were detected at concentrations above the Non-Residential IASLs. Specifically,
ethylbenzene was detected at concentrations ranging from 5.0 to 15 µg/m3 in indoor air samples
IAS-1, IAS-5, and IAS-10. Additionally, naphthalene was detected at concentrations ranging
from 0.37 to 1.4 µg/m3 in indoor air samples IAS-4, IAS-5, IAS-6, IAS-9, and IAS-10. slightly
above the Non-Residential IASL of 0.36 µg/m3 at five sampling locations with concentrations
ranging from 0.37 to 1.4 µg/m3. No other compounds were detected above Non-Residential
IASLs. It should be further noted that TCE was detected in only two indoor air samples at
concentrations well below the Non-Residential IASL of 1.8 µg/m3. Of the detections of TCE in
indoor air, neither were associated with samples collected from the USPS tenant space.

3.3 DEQ DWM Risk Calculations
H&H utilized the July 2022 DEQ risk calculator assuming a non-residential land use scenario to
evaluate calculated cumulative risks for the indoor air vapor intrusion pathway in each sampled
tenant space. H&H calculated cumulative risk using the highest concentrations of compounds
14
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Somerset Properties (SSP)/Continental Tire (SSP-001)/Brownfields Assessment/Additional VI Assessment/Final Report/VI Assessment Report_REEP-LRC(RN).doc
detected in each indoor air sample collected during the July 2022 sampling event to evaluate
each of tenant spaces. Results of the risk calculations are summarized below and included in
Appendix C.

Indoor Air Sample
Location
Non-Residential Worker
Carcinogenic Risk Hazard Index
IAS-1 3.5 x 10-6 0.16
IAS-2 1.7 x 10-6 0.089
IAS-3 1.8 x 10-6 0.095
IAS-4 2.3 x 10-6 0.14
IAS-5/IAS-DUP 4.5 x 10-6 0.26
IAS-6 4.4 x 10-6 0.30
IAS-7 2.2 x 10-6 0.063
IAS-8 1.1 x 10-6 0.066
IAS-9 2.6 x 10-6 0.087
IAS-10 1.3 x 10-5 0.89

As shown in the table above, calculated cumulative risks for a non-residential worker scenario
are within the acceptable carcinogenic risk of less than 1 x 10-4 and less than a hazard index of
1.0. Based on the evaluation of the July 2022 DEQ risk calculator results, there is no evidence of
a significant vapor intrusion concern for non-residential workers and therefore mitigation
measures to protect non-residential workers do not appear warranted.

4.0 Summary and Conclusions

H&H has completed vapor intrusion assessment activities for the warehouse building on the
REEP-LRC II Brownfields property located in Charlotte, North Carolina. Brownfields
assessment activities included collection of sub-slab vapor and indoor air samples to further
evaluate potential structural vapor intrusion. A brief summary of the Brownfields assessment
activities is provided below.

• Results of sub-slab vapor assessment activities indicate that 1,1-dichloroethane and TCE
were detected above the Non-Residential SGSLs in at least one of the sub-slab vapor
samples.

Calculated cumulative risk values for the soil gas to indoor air vapor intrusion pathway
for a non-residential worker exceed acceptable risk limits in the USPS tenant space.

• Results of indoor air assessment activities indicate that ethylbenzene and naphthalene
were detected above the Non-Residential SGSLs in at least one of the indoor air samples.

Calculated cumulative risk values for the indoor vapor intrusion pathway air for a non-
residential worker are within the acceptable carcinogenic risk of less than 1 x 10-4 and
less than a hazard index of 1.0.

In summary, results of vapor intrusion assessment activities indicate that structural vapor
intrusion into the warehouse building does not pose a significant risk for typical commercial
and/or industrial uses (i.e., those without sensitive populations). Based upon the results,
additional assessment does not appear warranted, and impacted media or media disturbed during
future redevelopment activities can be managed in accordance with the DEQ-approved EMP
and/or land use restrictions as outlined in a negotiated Brownfields Agreement.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are
likely not associated with vapor intrusion.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are
likely not associated with vapor intrusion.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are
likely not associated with vapor intrusion.
