1 INTRODUCTION
This Odor and Air Quality Management Plan was prepared as a companion document to the April
8, 2021, Raleigh MGP II site Environmental Management Plan (EMP) prepared by Aptus
Management, PLLC (Aptus), which was approved by the NC Department of Environmental
Quality (DEQ) on April 9, 2021.
The Plan describes the methods, procedures, and response actions for odor and perimeter air
quality monitoring during development to control for odors and fugitive emissions in order to
minimize impacts to the surrounding community. This Plan includes the following:
• Checks conducted at least three time per day to identify detectable and potentially
objectionable nuisance odors via olfactory observations and instrument monitoring;
• Real-time fence line monitoring conducted at a minimum of eight locations at least three
times per day for VOCs and particulates in ambient air;
• Verifying real-time monitoring data through collection of confirmatory air quality samples
and testing by EPA Method TO-15;
• Best management practices (BMPs) for site work to minimize odors and VOCs in ambient
air, including limiting open excavation work faces, using clean fill to create a physical
barrier, odor suppression, and immediately covering stockpiled waste material prior to
offsite disposal; and
• Contingency planning and corrective action utilizing physical methods to limit odors and
VOC emissions (e.g., suppression foams).
1.1 Site Location
The Raleigh MGP II site consists of 5.91 acres of land located on three contiguous lots. A Location
Map is attached as Figure 1 and the Existing Conditions C1.00 Plan prepared by McAdams is
attached as Figure 2.
1.2 Site History
The property was home to various industrial operations dating back to the late 1800s, including,
most importantly, a manufactured gas plant (MGP) that operated from 1916 until 1953. The MGP
operations caused contamination due to spillage and onsite disposal of tars and other wastes. By
1989, PSNC Energy Company had dismantled all MGP equipment and structures. Starting in
2001 and culminating in 2011, PSNC implemented four large-scale cleanup actions that included
removal and offsite disposal of 54,000 tons of contaminated material and using treatment
reagents to degrade the remaining pollution. The remediation was overseen by DEQ's Waste
Management Division, IHSB, Special Remediation Branch.
The past cleanup actions removed much of the contamination caused by the past MGP
operations. Remediation was conducted across the former MGP facility footprint, and the cleanup
areas were backfilled and covered with clean fill to allow site reuse and redevelopment.
Nevertheless, residual contamination remains in some areas below ground in soil and
groundwater.

Odor and Air Quality Management Plan November 4, 2021
Raleigh MGP 11 Page 2
The site is participating in the NC Brownfields Program. In November 2011, DEQ Brownfields
Agreement No. 13022-09-92 was recorded with Wake County that applied to 4.08 acres of the
Site where the MGP facility was located. According to DEQ, the original 2011 Brownfields
Agreement will be superseded by a new comprehensive agreement for the entire 5.91-acre
redevelopment site sometime in 2022.
1.3 Redevelopment Plan
The current phase of redevelopment consists of work on the western portion of the site and
includes demolition of existing improvements, which have largely been completed, construction
of a new stormwater culvert through the site and followed by construction of a mixed -use 436,000-
sq-ft building with 443 apartment units. The building will be seven levels in total, one ground level
of amenity, commercial and parking areas with six levels of apartments above. The ground level
will provide 27,000 square feet of commercial/retail space and 12,250 square feet of lobby space.
A 592-space parking structure will be completely wrapped by the commercial and residential
portion.
The redevelopment will take approximately two years to complete. Ground disturbance where
there is the potential for fugitive emissions and odors will occur largely in the first six months of
the project, November 2021 through April 2021, including the construction of the new stormwater
culvert. Some ground disturbance activities may continue throughout the first year of construction
for foundations. Monitoring for VOCs and odors will be conducted whenever there are
construction activities where there is the potential to generate fugitive emissions and odors.
1.4 Residual MGP Contamination
Gas Plant by-products and wastes are predominantly tars left over when coal was processed to
make a burnable gas. Compounds of concern are petroleum -based and include many of the same
chemicals as found in asphalt, heating oil and gasoline.
Specific pollutants at the Raleigh MGP II site included volatile organic compounds (VOCs) such
as benzene, toluene, ethylbenzene and xylenes (or BTEX), semi -volatile compounds
(naphthalene), and polycyclic aromatic hydrocarbons (or PAHs). The former cleanup areas and
the remaining known residual impacts are shown in the attached Brownfields Survey Plat as
Figure 3. Known residual contamination in relation to the existing and proposed stormwater
culverts and other site features is also shown in Figure 4. The extend of the MGP cleanup and
areas of clean fill are shown in Figure 5, which also shows the brownfields site boundaries
established by recombination.

2 REAL-TIME AIR MONITORING
November 4, 2021
Page 4
Most of the MGP wastes and impacted materials were removed by PSNC in a series of cleanups
that ended in 2011, but residual pockets remain which were infeasible to be removed. During
construction, residual MGP waste and impacted materials may be encountered from time to time.
Possible sources of fugitive odors and emissions include open ground disturbance work areas,
stockpiled impacted material, excavation, foundation spoils and other activities that may
encounter residual MGP wastes.
Real-time ambient air quality monitoring for particulates and volatile organic compounds (VOCs)
will be performed at the site perimeter at eight locations (Figure 6) and within the site at the
location of activities (i.e., ground disturbance) which could result in fugitive emissions or odors to
help ensure acceptable air quality conditions. Real-time air monitoring will be compared to site -
specific action levels to help direct fugitive emission and odor controls.
A low -detection photo -ionization ppbRae detector (PID) and an aerosol dust monitor will be used
to perform real-time field screening. This real-time data will document measured levels of
contaminants and help define when additional vapor, odor and/or dust suppression activities or
alteration of work activities are necessary.
2.1 Monitoring Parameters
For MGP-impacted material, benzene and naphthalene are key VOCs and benzene is the
compound that drives public health concerns due to its prevalence and relative volatility.
Moreover, benzene alone has a low exposure limit (EPA IRIS Inhalation Unit Risk 7.8 x 10-6 ug/m3)
to be used as a surrogate for the total VOC mixture found in fugitive emissions at MGP sites and
naphthalene (which is a sVOC and much less volatile than benzene). Therefore, we propose to
focus MGP air quality decisions and action levels on benzene. Benzene is a known human
carcinogen (EPA class A) and volatile (vapor pressure 75 mm Hg, 20 °C). This approach — using
benzene to set monitoring parameters -- is common and customary for monitoring fugitive
emissions at MGP sites (see, for example, Wisconsin DHS: MGP Air Guidance and NY DEC
Manufactured Gas Plants Program).
2.1.1 VOCs
Real-time monitoring for VOCs will be conducted using a ppbRAE or MiniRAE portable PID with
a 10.6ev lamp (or equivalent instrument). The PID will be used to non -selectively monitor VOC
concentrations. The PID will have a detection limit of 1 part per billion (ppb).
The PID will be used to monitor air quality at along the fence line and within the site at work areas.
Instrument readings will be measured over a 1-minute sample interval at each location. Instrument
readings will be observed and recorded on data sheets. If/when data is logged by the instrument,
the logs will be transferred from the data -logger to electronic files.
Documentation of routine, periodic calibration and/or "bump tests" in accordance with the
manufacturer's specifications will meet the equipment quality assurance/quality control (QA/QC)
for these units.
2.1.2 Particulates
Real-time monitoring of fugitive particulates will be conducted during perimeter monitoring and

Odor and Air Quality Management Plan November 4, 2021
Raleigh MGP 11 Page 5
within the site at work areas using a TSI Dust Trak II Aerosol Monitor, Thermo DataRAM pDR-
Dust Monitor, (or equivalent instrument). The detection limit for these instruments is 0.001
milligrams per cubic meter (mg/m3). Instrument readings will be observed and recorded. If/when
data is logged by the instrument, the logs will be transferred to electronic files.
Concentrations will be measured for a 1-minute sample interval at each perimeter monitoring
location and within the site at work areas and the average measurements will be recorded. The
result will be compared to the action level for particulates to assess air quality. Visible emissions
of dust leaving the site will be evaluated and addressed regardless of instrument readings.
2.2 Real -Time Action Levels
There is no single set of ambient air quality rules or standard that apply to compounds of concern
at MGP sites. The ambient air goals and action levels consider a combination of enforceable
standards (e.g., National Ambient Air Quality Standards; NC Section .0400 Ambient Air Quality
Standards) and non -enforceable guidelines (e.g., risk -based and various adopted state
guidelines), which provide concentrations below which unacceptable risk is not expected for the
general public.
The real-time action levels were set following established methods and are consistent with air
quality action levels set for fugitive VOC and particulate emissions at other MGP remediation
projects. The most generally accepted protective real-time action level, which has been adopted
by a number of states, is 1,000 ppb (1 ppm) for VOCs (Wisconsin DHS: MGP Air Guidance, NY
DEC Manufactured Gas Plants Program)and the NAAQS PM10 standard of 150 pg/m3 for
particulates. NC's particulate standard is also 150 pg/m3 (15A NCAC 02D .0403).

2.2.1 VOCs
For VOCs, including benzene and other contaminants of concern, there are no enforceable
standards upon which to establish action levels, so project -specific air quality objectives are set
considering MGP waste characteristics, EPA risk -based exposure guidelines and the practical
capability of field screening and analytical instruments.

Odor and Air Quality Management Plan November 4, 2021
Raleigh MGP 11 Page 6
As outlined as outlined above, the most common accepted protective real-time action level is
1,000 ppb (1 ppm) for fugitive VOCs at MGP cleanup sites and other response actions. Benzene
is the most restrictive VOC at MGP sites and is used as the sentinel compound for VOCs.
As a check on the protectiveness of the perimeter 1,000 ppb real-time VOC action level, we
calculated hypothetical acceptable offsite ambient levels assuming 4 months of exposure
occurring 8 hours per day to both benzene and naphthalene. This resulted in hypothetical
acceptable ambient levels of 106.5 ppb for benzene and 14.9 and 11.9 ppb for naphthalene (see
Table 2 and 3).
The real-time action level at the site perimeter of 1,000 ppb total VOCs is expected to be protective
and ensure the exposure to the ambient levels presented above would not occur. The rationale
for why the perimeter 1,000 ppb action level would be protective is as follows:
• Fugitive emissions are expected only intermittently and not expected to result in
unacceptable long emission events or elevated ambient contaminant levels lasting more
than one hour..
• The real-time action level is for a short, one -minute duration versus longer term exposure
which is expected to be at lower concentrations
• Only a fraction of the total VOCs will be benzene, the contaminant of most concern, and
an even smaller fraction will be naphthalene due to is relatively low vapor pressure
• Attenuation will occur between the site perimeter and offsite receptors.
2.2.2 Particulates
For particulates emissions, it is common and customary to utilize the NAAQS for total PM10 and
that is the action level adopted here. The NAAQS 24-hour average concentration of 150 pg/m3
for PM10 will be used as the project air quality objective for particulates. NC's particulate standard
is also 150 pg/m3 (15A NCAC 02D .0403).
This particulate action level has been used at a number of MGP cleanup sites, it is both a NC
state and federal standard and is the generally -accepted particulate monitoring level used.
2.3 Real -Time Monitoring Frequency & Locations
Real-time monitoring will be conducted no less than three times per day when there are
construction activities underway with the potential to result in fugitive emissions or odors. Once
at the onset of work, mid -day and approximately one hour before completion of work. Real-time
monitoring would also be conducted when site conditions change or new activities are started
where fugitive emissions may occur. Real-time monitoring would be done in conjunction with
nuisance odor assessments. Real-time ambient air quality monitoring for particulates and volatile
organic compounds (VOCs) will be performed at the site perimeter at eight locations (Figure 6)
and within the site at the location of activities (i.e., ground disturbance) which could result in
fugitive emissions or odors to help ensure acceptable air quality conditions.. An Air Monitoring
Data Form will be used to record measured concentrations from the dust monitor and
photoionization detector (PID) (see attached).

Raleigh MGP 11 Page 7
3 TIME -INTEGRATED AIR QUALITY MONITORING
In addition to real-time monitoring, time -integrated air quality monitoring will be conducted to
establish baseline air quality conditions for specific contaminants and done at least monthly on a
confirmatory basis to help demonstrate ongoing acceptable air quality conditions.
3.1 Pre -Construction Air Quality Monitoring
The objective of pre -construction baseline air sampling is to document typical air quality prior to
the start of site work that includes ground disturbance. The sampling data will be used to compare
air quality data with air quality conditions measured during active construction activities that
include ground disturbance and contact with residual MGP-impacted materials. Samples will be
collected with SUMMA canasters and analyzed for TO-15 analytes, including for BTEX and
naphthalene, chlorinated VOCs (PCE and daughter products), other known VOC site
contaminants, and particulate matter.
The samples will be collected at the four locations shown on Figure 6 at breathing zone height,
for a duration of 8 hours during the day, the length of the typical work shift. Site conditions at the
time of sampling will be documented (including photos).
3.2 Confirmatory Air Quality Testing
The first sampling event will occur at the start of work that includes ground disturbance for the
stormwater culvert construction. Thereafter, monitoring will occur on a monthly basis, at a
minimum, with confirmatory air samples for TO-15 analytes, for BTEX and naphthalene,
chlorinated VOCs (PCE and daughter products), other known VOC site contaminants, and
particulate matter will be collected once site works gets underway. The confirmatory samples will
be collected from the downwind location of a suspected emission source or the location that is
likely to have the highest concentration of airborne contaminants. The samples will be collected
at breathing zone height, for a duration of 8 hours during the day, the length of the typical work
shift. Site conditions at the time of sampling will be documented (including photos).
We will also conduct a TO-15 sampling during the first odor causing event with concurrent ambient
air screening to get an understanding of what compounds are present in the air compared to the
real-time screening results. This information may result in the need to revise any approved action
levels.
Sampling may be conducted elsewhere included offsite to evaluate possible ambient levels of
contaminants. Additional sampling would be conducted in close coordination with DEQ.
3.3 Monitoring Using SUMMA Canister Samples
Time -weighted ambient air sampling will be conducted for VOCs using EPA Method TO-15 from
SUMMA canisters samples (EPA 1999b). Note that naphthalene can be analyzed with the TO-15
method and will be requested. Samples for VOCs will be collected using laboratory certified, 6.0-
liter SUMMA canisters and flow controllers. Sampling and laboratory analysis will be completed
in accordance with accordance with DEQ Division of Waste Management (DWM) Vapor Intrusion
Guidance Document (March 2018).and ITRC guidance documents
Per DEQ VI Guidance, Summa canisters that have lost greater than 10% of the initial recorded
lab vacuum when received in the field will not be used for sampling. It is assumed that Summa

Odor and Air Quality Management Plan November 4, 2021
Raleigh MGP 11 Page 8
canisters are issued with a maximum achievable pressure of 30" Hg. If canisters are received in
the field with less than 27" Hg, initial lab pressure measurements will be documented to confirm
less than a 10% volume loss or a replacement summa canister obtained. Otherwise, sample
results may be rejected.
We will indicate a targeted final vacuum reading of at least -5" Hg. Note if the vacuum
measurement is less than this, sample acceptance will be in jeopardy and DEQ Brownfields may
request a resample. Real-time monitoring and odor assessment will be conducted when time -
weighted sampling occurs
3.4 Particle Monitoring
Monitoring for particulates will employ a combination of real-time techniques for making action
level decisions and time weighted techniques to verify compliance with NAAQS. Monitoring will
use Federal Reference Method (FRPS) 1287-065 or equivalent (U.S. EPA 2003c) for PM10 for
construction -phase activities with a 1 mg/m3 action level.

Odor and Air Quality Management Plan November 4, 2021
Raleigh MGP 11 Page 9
4 ODOR ASSESSMENT & MANAGEMENT
4.1 Objectives
Checking for odors and preventing nuisances odors will be a key issue during all work and
operations with the potential of handling or disturbing MGP-impacted material. Regular
assessment of odors will be conducted, concurrently with the other real-time monitoring for VOCs
and particulate.
To avoid olfactory fatigue, personnel conducting odor assessments will not work directly in areas
where fugitive emissions and odors could be present for at least an hour before conducting the
assessment.
4.2 Odor Assessment Frequency and Locations
Odor assessment observations will be made at least three times during the workday or more
frequently, if needed. The assessor making olfactory (smell) observations at locations will include
along the perimeter of the Site at the eight locations shown on Figure 6 and may be expanded
elsewhere onsite and offsite (along public right-of-way and roads). Any additional locations
surveyed by the team will be noted on the Odor Assessment Form provided in the appendices.
4.3 Odor Classification
We will be using a four -level classification of possible odor situations and observations that will
be used to trigger odor control response actions:
• Level 0 — Nominal odors may be present onsite, but odor is not detectable off -site, or very
minimal and very infrequent.
• Level 1 — On and off -site odors are present, but the odors are not strong, not steady, and
there is minimal potential for impact to the community, or the odors are not noticed by the
community. This is an indication that odor control measures at the Site are adequate.
• Level 2 - Odors are stronger than a "1" and relatively steady, particularly onsite. The
community is not necessarily aware of the odors, but community recognition may occur,
and additional odor control measures must be immediately implemented. A follow-up
reassessment of possible odors will be conducted after implementation of odor control
measures.
• Level 3 - Odors are very strong and the community is aware of and reacting to the odors.
Odor -generating activities must cease, and full odor control measures implemented. The
situation must be re-evaluated prior to re -initiating work activities. Level 3 odors will trigger
TO-15 sampling.

Odor and Air Quality Management Plan November 4, 2021
Raleigh MGP // Page 10
5 ODOR AND FUGITIVE EMISSION CONTROLS
Control of odors and fugitive emissions is a key issue for site work and for all operations that
include ground disturbance and possible exposure or handling of MGP-impacted material. All
contractors performing excavation and activities that involve ground disturbance will aggressively
control odors and fugitive emissions. Best management practices will include:
• Stockpiled impacted material will be covered in accordance with EMP.
• Odors and fugitive emissions will be controlled by minimizing the excavation areas and
open faces
• Covering the excavation working faces with clean fill, plastic sheeting and other measures
as needed
• Applying VOC and odor -control foams/suppression to the exposed excavations if there is
the potential for odors or fugitive emissions.
The VOC/odor-control foam selected for the project site is a product supplied by ATMOS. Use of
the foam, when needed, provides immediate emissions control by stopping VOC volatilization.
The foaming materials are safe, non -toxic and has been approved and used for odor control at
MGP sites, brownfields sites, landfills and cleanup sites by state environmental agencies and the
USEPA. The foam's safety data sheet and certification that the material does not contain PFAS
are attached.
Inspections of best mgmt practices/controls will be conducted by the environmental professional
(Mr. Hill or his designee) weekly during soil disturbance and more often if odors or action levels
are reported.

Odor and Air Quality Management Plan November 4, 2021
Raleigh MGP 11 Page 11
6 REPORTING
6.1 Field logs
Field logs will be maintained throughout the project to accumulate site conditions on a daily basis
that have or may have an effect on Site air quality conditions. Information to be recorded in the
field logbook will include:
• description of site activities;
• weather conditions;
• general real-time perimeter monitoring observations;
• action levels exceedances; and
• emission abatement measures implemented in response to action level exceedances.
The data recorded in the field logs will be supplemented by data recorded on specific real-time
and time -integrated field data sheets.
6.2 Real -Time Monitoring Data
The real-time air monitoring data will be recorded on the field data sheets and stored in an
electronic database. Field data including measured concentrations recorded during perimeter air
monitoring rounds, calibration records, maintenance, sampling irregularities, and repairs will be
recorded on data sheets and compiled in the field logbook for the real-time air monitoring.
The real-time sampling results will be routinely reported to the site manager to allow prompt
evaluation and response to potential emission problems when action levels have been
approached or exceeded.
6.3 Time -Integrated Sampling Data
Field data, including equipment calibration, sample identification; equipment maintenance,
sampling irregularities, and shipments will be recorded on the time -integrated sampling field data
sheets and compiled in the spreadsheet where field log data will be summarized. A set of field
logbooks will be maintained for the time -integrated sampling network to log daily information of
the nature described above, pertinent to documenting the time -integrated sampling program.
Preliminary results will be reported to the site manager to assess potential air quality concerns
due to site activities. The accumulated time -integrated results, field data, and comparison to the
project air quality standards will be presented in the Ambient Air Monitoring Report upon the
conclusion of the remediation project.
6.4 Notification and Reporting
48-hour notification (via email) will be provided to DEQ in the event of action level exceedances
and odors at level 3. Notification will include copies of field log forms and other pertinent
information. Lab data with summary tables will be provided to DEQ if detected ambient air levels
exceed residential screening levels within 10 days of receipt of data from the lab
Monthly summary reports will be prepared and provided to DEQ. Longer -term reporting will be
included with regular EMP updates and reports provided to DEQ.

Dear Mr. Herring:
S&ME, Inc. (S&ME) is pleased to provide this report detailing the area monitoring performed during the
revitalization and development of the W. Cabarrus Street Brownfield Site located in Raleigh, North Carolina. The
purpose of the assessment was to monitor the site for airborne contamination associated with the pre-existing
subsurface contamination including benzene, toluene, ethylbenzene, and xylene (BTEX), volatile organic
compounds, and polyaromatic hydrocarbons (PAH) during excavation activities on October 13, 2021. The limited
sampling was performed in general accordance with S&ME Proposal No. 215242, dated June 10, 2021. The
following report includes the project background, our assessment procedures, our findings, and our conclusions
and recommendations.
This report is provided for the sole use of Clancy & Theys Construction Company (C&T) as it relates to occupational
exposure of BTEX, PAHs and trichloroethylene. Use of this report by any other parties will be at such party's sole risk
and S&ME disclaims liability for any such use or reliance by third parties. The information presented are indicative of
conditions only during the time of the assessment and of the specific areas referenced.
S&ME appreciates this opportunity to provide our services to you. Please call if you have questions concerning
this summary.

Cabarrus Street
Raleigh, North Carolina
S&ME Project No. 215242 11 E
1.0 Introduction
The Cabarrus Street site located at 516 W. Cabarrus Street in Raleigh, North Carolina is currently undergoing
select excavation as part of the revitalization and development project. Previous reports by others indicate the
516 W. Cabarrus Street site is a North Carolina Brownfield Site with potential subsurface contamination including
benzene, toluene, ethylbenzene, and xylene (BTEX), chlorinated solvents, and polyaromatic hydrocarbons (PAH).
As required by the Environmental Management Plan (EMP) prepared by Aptus Management, PLLC, dated April 8,
2021, S&ME prepared and conducted sampling to determine the potential exposure to workers during the initial
excavation and trenching activities for the stormwater culvert.
S&ME conducted sampling on June 18, 2021, to determine the potential occupational exposure of BTEX,
chlorinated solvents and PAHs to workers at levels exceeding the Occupational Safety and Health (OSHA)
Permissible Exposure Limits (PELs) and the American Conference of Governmental Industrial Hygienists (ACGIH)
Threshold Limit Values (TLVs). C&T and Carolina Civilworks, Incorporated (CCI) simulated conditions that would
represent the culvert excavation by preparing an area approximately six feet wide by twelve feet long, to a depth
of approximately fifteen feet, in a location where previous groundwater monitoring data indicated the highest
concentrations of BTEX, chlorinated solvents and PAHs.
During the field screening activities, no elevated levels of BTEX, PAHs nor chlorinated hydrocarbons (TCE) were
detected during the excavation utilizing the PID and the Drager CMS Analyzer as reported in the S&ME Report
titled Cabarrus Street Exposure Assessment, dated July 6, 2021.
C&T requested a follow-up visit October 12, 2021, to conduct additional ambient air monitoring of the Cabarrus
Site due to recent air quality concerns and odor complaints from the residential neighbors located across the
street from the revitalization site. S&ME conducted additional monitoring of the site on October 13, 2021.
Field Services
BTEX Field Screening
S&ME utilized a MiniRAE 3000 Model PGM-7320 Photo Ionization Detector (PID) with a 10.6 eV lamp to measure
the concentrations of volatile organic compounds (VOCs) and PAHs at the breathing zone. The background levels
were reported as 0.0 parts per million (ppm). The PID operated continuously during the monitoring and levels
were reported as 0.0 ppm along the construction fence surrounding 516 W. Cabarrus Street. Additionally, S&ME
visually divided the property into three quadrants and walked each quadrant to measure the ambient air with the
PID. These locations included the excavated area of contaminated soil where the concrete slab was uncovered,
the pile of asphalt debris, and the pile of concrete debris. The attached drawing depicts the locations of recorded
measurements with the understanding the PID ran continuously during the site evaluation.
During the site walk at 2 PM in the afternoon of October 13, 2021, the following activities were observed:
The excavation of the concrete foundation was underway.

♦ Dump trucks were entering and leaving the site.
♦ Misting during the operation of the concrete crushing equipment.
♦ The temperature was recorded as 87 degrees Fahrenheit with light variable winds at 3 miles per hour and
relative humidity of 62 percent.
Results
BTEX AND PAHs Vapor Field Screening Results
During the field screening activities utilizing the PID, levels were reported as 0.0 ppm as representation of BTEX
and PAHs during the site walk. These results are consistent with the results recorded during the initial assessment
conducted on June 18, 2021.
Conclusions and Recommendations
Although levels were reported as 0.0 ppm on October 13, 2021, C&T, S&ME and Aptus Management are
discussing additional monitoring to ensure levels do not exceed 100 ppm.
Based on monitoring results, neighborhood concerns, the North Carolina Department of Environmental Quality,

Cabarrus Street Exposure Assessment
Cabarrus Street
Raleigh, North Carolina
S&ME Project No. 215242 11 E
1.0 Introduction
The Cabarrus Street site located at 516 W. Cabarrus Street in Raleigh, North Carolina is scheduled to undergo
revitalization and development. Previous reports by others indicate the 516 W. Cabarrus Street site is a North
Carolina Brownfield Site with potential subsurface contamination including benzene, toluene, ethylbenzene, and
xylene (BTEX), chlorinated solvents, and polyaromatic hydrocarbons (PAH). The Environmental Management Plan
(EMP) prepared by Aptus Management, PLLC, dated April 8, 2021, required C&T to develop a sampling strategy to
determine the potential exposure to workers during the initial excavation and trenching activities for the
stormwater culvert. The redevelopment project includes the installation of a culvert with the approximate
dimensions of 25 feet wide by approximately 800 to 1,000 linear feet long. The culvert excavations will extend 15
to 20 feet below grade, in 50-foot sections.
S&ME developed a sampling strategy to determine the potential occupational exposure of BTEX, chlorinated
solvents and PAHs to workers at levels exceeding the Occupational Safety and Health (OSHA) Permissible
Exposure Limits (PELs) and the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold
Limit Values (TLVs). C&T and Carolina Civilworks, Incorporated (CCI) simulated conditions that would represent
the culvert excavation by preparing an area approximately six feet wide by twelve feet long, to a depth of
approximately fifteen feet, in a location where previous groundwater monitoring data indicated the highest
concentrations of BTEX, chlorinated solvents and PAHs.
Hexavalent Chromium was included in the sampling strategy presented in the proposal number 215242 prepared
by S&ME, dated June 10, 2021. However, due to the short duration of the excavation, the sampling volume
required to properly access the potential exposures to Hexavalent Chromium would be insufficient and potentially
invalidate the data. If additional testing is conducted during the excavation of the stormwater culvert, Hexavalent
Chromium may be sampled at a later date.
Field Services
BTEX Field Screening
C&T, CCI and S&ME discussed the installation of the culvert associated with the excavation including the
following:
CCI anticipates the employees will enter the excavation for specific tasks intermittently during an eight -
hour shift, totaling a maximum of two hours per day.
The area of the simulated excavation was marked with white spray -paint. (Refer to the drawing in
Appendix 1)
CCI indicated the trench box would be installed once the excavation was complete.
The location of the simulation trench was in -filled from previous soil remediation with clean -fill.
Temperatures during the simulation exercise would depict similar conditions during the excavation with
temperatures ranging between 84 degrees Fahrenheit and 106 degrees Fahrenheit.

S&ME Project No. 215242
The excavated soil was scheduled to be removed and stockpiled on black polyethylene sheeting with
straw bales serving as a berm around the outer perimeter of the soil pile.
S&ME utilized a MiniRAE 3000 Model PGM-7320 Photo Ionization Detector (PID) with a 10.6 eV lamp to measure
the concentrations of volatile organic compounds (VOCs) and PAHs at approximately three- to four- foot depth
intervals during the excavation. CCI began the excavation on June 18, 2021, utilizing a CAT excavator, Number
KTN20031 to perform the excavation. S&ME collected the following readings with the PID (utilizing tubing to
reach the lower depths of the trench):
Background reading: 0.0 parts per million (ppm)
Initial ground break at one foot: 0.0 ppm
Approximately four feet at edge of trench: 1.5 ppm
Approximate seven -foot depth: 1.3 ppm
Approximately nine -foot depth (petroleum odor): 1.1 ppm
Approximate fifteen -foot depth (groundwater seepage observed with sheen): 1.6 ppm
Ground level adjacent to trench: 1.1 - 1.8 ppm (peak)
S&ME utilized a Drager Chip Management System (CMS) Analyzer to screen for the presence of chlorinated
solvents - trichloroethylene (TCE) vapors in the base of the trench box on June 24, 2021. The TCE vapors were
measured by initially inserting a TCE chip into the analyzer prior to lowering the meter within five to six inches of
the trench's bottom. After a result was shown on the analyzer, the PCE chip was then ejected and a TCE chip was
then inserted and the steps were repeated to ensure two consecutive readings of 0.0 ppm were recorded.
Results
BTEX, PAHs and TCE Vapor Field Screening Results
During the field screening activities, no elevated levels of BTEX, PAHs nor chlorinated hydrocarbons (TCE) were
detected during the excavation utilizing the PID and the Drager CMS Analyzer.
Conclusions and Recommendations
Based on the limited soil assessment results from the June 18t" and 24t", 2021, sampling events, the following
conclusions are presented:
S&ME collected eight PID readings for BTEX and PAHs during the excavation of the trench with a
maximum depth of approximately fifteen feet. Based on the field screening results, the PID did not alarm
and all readings were below 100 ppm.
S&ME field screened the base of the trench box for vapor concentrations of TCE using the Drager CMS
Analyzer. Based on the field screenings, no detectable concentrations of TCE were measured.

Based upon both sets of data, the reported levels of contaminants of concern did not exceed the OSHA
PELs and ACGIH TLVs.
Based on the above, S&ME recommends the following:
Conduct periodic work area air monitoring and/or personal air monitoring during the installation of the
proposed stormwater culvert to evaluate concentrations of BTEX, PAHs, and chlorinated solvents to
ensure the workers are not exposed to concentrations above the OSHA PELs and ACGIH TLVs.
Be prepared to use engineering controls (e.g. fan) or personal protective equipment to maintain safe
levels of worker exposures.
Maintain an awareness of possible VOC impacted soil or groundwater.
Be prepared to contain and properly dispose of VOC impacted soil and groundwater, if needed.

Technical Note TN-106
Revised 08/2010
Correction Factors, Ionization Energies*, And Calibration Characteristics
Correction Factors and Ionization Energies
RAE Systems PIDs can be used for the detection of
a wide variety of gases that exhibit different
responses. In general, any compound with
ionization energy (IE) lower than that of the lamp
photons can be measured.* The best way to
calibrate a PID to different compounds is to use a
standard of the gas of interest. However, correction
factors have been determined that enable the user to
quantify a large number of chemicals using only a
single calibration gas, typically isobutylene. In our
PIDs, correction factors can be used in one of three
ways:
1) Calibrate the monitor with isobutylene in the
usual fashion to read in isobutylene equivalents.
Manually multiply the reading by the correction
factor (CF) to obtain the concentration of the gas
being measured.
2) Calibrate the unit with isobutylene in the usual
fashion to read in isobutylene equivalents. Call
up the correction factor from the instrument
memory or download it from a personal
computer and then call it up. The monitor will
then read directly in units of the gas of interest.
3) Calibrate the unit with isobutylene, but input an
equivalent, "corrected" span gas concentration
when prompted for this value. The unit will then
read directly in units of the gas of interest.
* The term "ionization energy" is more scientifically correct and
replaces the old term "ionization potential. "High -boiling ("heavy')
compounds may not vaporize enough to give a response even when
their ionization energies are below the lamp photon energy. Some
inorganic compounds like H2O2 and NO2 give weak response even
when their ionization energies are well below the lamp photon energy.
Example 1:
With the unit calibrated to read isobutylene
equivalents, the reading is 10 ppm with a 10.6 eV
lamp. The gas being measured is butyl acetate,
which has a correction factor of 2.6. Multiplying 10
by 2.6 gives an adjusted butyl acetate value of 26
ppm. Similarly, if the gas being measured were
trichloroethylene (CF = 0.54), the adjusted value
with a 10 ppm reading would be 5.4 ppm.
0-12AM];
5 Y S i E M 5
Example 2:
With the unit calibrated to read isobutylene
equivalents, the reading is 100 ppm with a 10.6 eV
lamp. The gas measured is m-xylene (CF = 0.43).
After downloading this factor, the unit should read
about 43 ppm when exposed to the same gas, and
thus read directly in m-xylene values.
Example 3:
The desired gas to measure is ethylene dichloride
(EDC). The CF is 0.6 with an 11.7 eV lamp.
During calibration with 100 ppm isobutylene, insert
0.6 times 100, or 60 at the prompt for the calibration
gas concentration. The unit then reads directly in
EDC values.
Conversion to mg/m3
To convert from ppm to mg/m3, use the following
formula:
Cone. (mg/m3) _ [Conc.(ppmv) x mol. wt. (/e moleE
molar gas volume (L)
For air at 25 °C (77 °F), the molar gas volume is
24.4 L/mole and the formula reduces to:
Conc.(mg/m) = Conc.(ppmv) x mol. wt. (g/mole) x 0.041
For example, if the instrument is calibrated with a
gas standard in ppmv, such as 100 ppm isobutylene,
and the user wants the display to read in mg/m3 of
hexane, whose m.w. is 86 and CF is 4.3, the overall
correction factor would be 4.3 x 86 x 0.041 equals
15.2.
Correction Factors for Mixtures
The correction factor for a mixture is calculated
from the sum of the mole fractions Xi of each
component divided by their respective correction
factors CFi:
CFmix = 1 / (Xi/CFi + X2/CF2 + X3/CF3 + ... Xi/CFi)
Thus, for example, a vapor phase mixture of 5%
benzene and 95% n-hexane would have a CFmix of
CFmix = 1 / (0.05/0.53 + 0.95/4.3) = 3.2. A
reading of 100 would then correspond to 320 ppm
of the total mixture, comprised of 16 ppm benzene
and 304 ppm hexane.

Web Site: www.raesystems.com

For a spreadsheet to compute the correction factor
and TLV of a mixture see the appendix at the end of
the CF table.
TLVs and Alarm Limits for Mixtures
The correction factor for mixtures can be used to set
alarm limits for mixtures. To do this one first needs
to calculate the exposure limit for the mixture. The
Threshold Limit Value (TLV) often defines
exposure limits. The TLV for the mixture is
calculated in a manner similar to the CF calculation:
TLV mix = 1 / (Xi/TLV1 + X2/TLV2 +
X3/TLV3 +... Xl/TLVI)
In the above example, the 8-h TLV for benzene is
0.5 ppm and for n-hexane 50 ppm. Therefore the
TLV of the mixture is TLVmix = 1 / (0.05/0.5 +
0.95/50) = 8.4 ppm, corresponding to 8.0 ppm
hexane and 0.4 ppm benzene. For an instrument
calibrated on isobutylene, the reading corrsponding
to the TLV is:
Alarm Reading = TLVmix / CFmix = 8.4 / 3.2 = 2.6 ppm
A common practice is to set the lower alarm limit to
half the TLV, and the higher limit to the TLV.
Thus, one would set the alarms to 1.3 and 2.6 ppm,
respectively.
Calibration Characteristics
a) Flow Configuration. PID response is essentially
independent of gas flow rate as long as it is
sufficient to satisfy the pump demand. Four main
flow configurations are used for calibrating a PID:
1) Pressurized gas cylinder (Fixed -flow
regulator): The flow rate of the regulator
should match the flow demand of the
instrument pump or be slightly higher.
2) Pressurized gas cylinder (Demand -flow
regulator): A demand -flow regulator better
matches pump speed differences, but results in
a slight vacuum during calibration and thus
slightly high readings.
3) Collapsible gas bag: The instrument will
draw the calibration gas from the bag at its
normal flow rate, as long as the bag valve is
large enough. The bag should be filled with
enough gas to allow at least one minute of flow
(— 0.6 L for a MiniRAE, —0.3 L for
MultiRAE).
1-IFNI W 112 IL 1:
5 Y I S i E An 5
Technical Note TN-106
Revised 08/2010
4) T (or open tube) method: The T method uses
a T junction with gas flow higher than the pump
draw. The gas supply is connected to one end
of the T, the instrument inlet is connected to a
second end of the T, and excess gas flow
escapes through the third, open end of the T.
To prevent ambient air mixing, a long tube
should be connected to the open end, or a high
excess rate should be used. Alternatively, the
instrument probe can be inserted into an open
tube slightly wider than the probe. Excess gas
flows out around the probe.
The first two cylinder methods are the most
efficient in terms of gas usage, while the bag and
T methods give slightly more accurate results
because they match the pump flow better.
b) Pressure. Pressures deviating from atmospheric
pressure affect the readings by altering gas
concentration and pump characteristics. It is best
to calibrate with the instrument and calibration
gas at the same pressure as each other and the
sample gas. (Note that the cylinder pressure is not
relevant because the regulator reduces the
pressure to ambient.) If the instrument is
calibrated at atmospheric pressure in one of the
flow configurations described above, then 1)
pressures slightly above ambient are acceptable
but high pressures can damage the pump and 2)
samples under vacuum may give low readings if
air leaks into the sample train.
c) Temperature. Because temperature effects gas
density and concentration, the temperature of the
calibration gas and instrument should be as close
as possible to the ambient temperature where the
unit will be used. We recommend that the
temperature of the calibration gas be within the
instrument's temperature specification (typically
14' to 113' F or -10' to 45' Q. Also, during
actual measurements, the instrument should be
kept at the same or higher temperature than the
sample temperature to avoid condensation in the
unit.
d) Matrix. The matrix gas of the calibration
compound and VOC sample is significant. Some
common matrix components, such as methane and
water vapor can affect the VOC signal. PIDs are

most commonly used for monitoring VOCs in air,
in which case the preferred calibration gas matrix
is air. For a MiniRAE, methane, methanol, and
water vapor reduce the response by about 20%
when their concentration is 15,000 ppm and by
about 40% at 30,000 ppm. Despite earlier reports
of oxygen effects, RAE PID responses with 10.6
eV lamps are independent of oxygen
concentration, and calibration gases in a pure
nitrogen matrix can be used. H2 and CO2 up to 5
volume % also have no effect.
e) Concentration. Although RAE Systems PIDs
have electronically linearized output, it is best to
calibrate in a concentration range close to the
actual measurement range. For example, 100
ppm standard gas for anticipated vapors of 0 to
250 ppm, and 500 ppm standard for expected
concentrations of 250 to 1000 ppm. The
correction factors in this table were typically
measured at 50 to 100 ppm and apply from the
ppb range up to about 1000 ppm. Above 1000
ppm the CF may vary and it is best to calibrate
with the gas of interest near the concentration of
interest.
f) Filters. Filters affect flow and pressure
conditions and therefore all filters to be used
during sampling should also be in place during
calibration. Using a water trap (hydrophobic
filter) greatly reduces the chances of drawing
water aerosols or dirt particles into the instrument.
Regular filter replacements are recommended
because dirty filters can adsorb VOCs and cause
slower response time and shifts in calibration.
g) Instrument Design. High -boiling ("heavy") or
very reactive compounds can be lost by reaction
or adsorption onto materials in the gas sample
train, such as filters, pumps and other sensors.
Multi -gas meters, including EntryRAE,
Mult1RAE and AreaRAE have the pump and other
sensors upstream of the PID and are prone to
these losses. Compounds possibly affected by
such losses are shown in green in the table, and
may give slow response, or in extreme cases, no
response at all. In many cases the multi -gas
meters can still give a rough indication of the
relative concentration, without giving an accurate,

Revised 08/2010
quantitative reading. The ppbRAE and MiniRAE
series instruments have inert sample trains and
therefore do not exhibit significant loss;
nevertheless, response may be slow for the very
heavy compounds and additional sampling time
up to a minute or more should be allowed to get a
stable reading.
Table Abbreviations:
CF = Correction Factor (multiply by reading to get
corrected value for the compound when
calibrated to isobutylene)
NR= No Response
IE = Ionization Energy (values in parentheses are
not well established)
C = Confirmed Value indicated by "+" in this
column; all others are preliminary or
estimated values and are subject to change
ne = Not Established ACGIH 8-hr. TWA
C## = Ceiling value, given where 8-hr.TWA is not
available
Disclaimer:
Actual readings may vary with age and cleanliness
of lamp, relative humidity, and other factors. For
accurate work, the instrument should be calibrated
regularly under the operating conditions used. The
factors in this table were measured in dry air at
room temperature, typically at 50-100 ppm. CF
values may vary above about 1000 ppm.

Compounds indicated in green can be detected using a MiniRAE 2000 or ppbRAE/+
with slow
response, but
may be lost
by
adsorption on a MultiRAE or EntryRAE. Response on multi -gas
meters can give
an indication of relative concentrations,
but may not
be quantitative and for some chemicals no response is observed.

Like the desktop models, it has manual and programmable data
logging functions. In addition, the handheld model also has a
single -point data logging capability. Single -point data collection
is used for walk-through industrial hygiene surveys and indoor
The DustTrak II desktop models come with USB (device and host), air quality investigations.
Ethernet, and analog and alarm outputs allowing remote access
to data. User adjustable alarm setpoints for instantaneous or
15-minute short-term excursion limit (STEL) are also available
on desktop models. The alarm output with user -defined setpoint
alerts you when upset or changing conditions occur.
The DustTrak II desktop monitors have several unique features;
+ Measure aerosols in high concentrations up to 400 mg/m3.
+ External pump (Model 8530EP) with low power consumption for
continuous, unattended monitoring in remote outdoor locations.
+ Gravimetric sampling capability using a 37-mm filter cassette
which can be inserted in -line with the aerosol stream allowing
you to perform an integral gravimetric analysis for custom
reference calibrations.
+ Zeros automatically using the external zeroing module. This
optional accessory is used when sampling over extended periods
of time. By zeroing the monitor during sampling, the effect of
zero drift is minimized.
+ STEL alarm feature for tracking 15-minute average mass
concentrations when alarm setpoint has been reached
for applications like monitoring fugitive emissions at
hazardous waste sites.
+ Provide for environmental protection and tamper -proof security
using an environmental enclosure, This optional accessory encloses
the instrument within a waterproof, lockable, custom -designed case.
+ Condition the sample air stream before entering the instrument
optics using a heated inlet sample conditioner (designed for use
