1 INTRODUCTION
On behalf of Chronicle Land LLC, Cardno, Inc. is pleased to submit this subsurface environmental assessment
Report of Findings in support of a Brownfields Agreement at the former Chronicle Mill property located at 96
Catawba Street in Belmont, Gaston County, North Carolina. The site is located to the east of the central business
district of Belmont, in an area characterized by mixed use as former industrial, commercial, and residential
development. According to the Gaston County website, the site consists of five parcels totalling 6.35 acres with
parcel identification numbers 125928,125929, 125930, 125931, and 125932. The facility structures include one
main mill building and several smaller adjacent structures that total approximately 108,000 square feet. Figure 1
shows the site and vicinity on part of a USGS Topographic Quadrangle Map, and Figure 2 provides a site and
immediate vicinity plan on an aerial photograph overlay from the Gaston County website.
Chronicle Land LLC submitted an application for Brownfields Agreement on the basis of site history, prior environmental assessment, and soil remediation at the Chronicle Mill property. Representatives of Chronicle Land,
Cardno, and the North Carolina Brownfields Program met at the property on December 12, 2014, to evaluate environmental assessment necessary to support the finalization of a Brownfields Agreement for the site. A Work
Plan was developed by Cardno on behalf of Chronicle Land, LLC and submitted to the North Carolina Brownfield Program on February 9, 2015. Review and approval of the Work Plan with modifications were provided by Tony
Duque, Project Manager of the Brownfields Program on June 9, 2015. This Report of Findings presents the results of site assessment activities conducted in accordance with the Work Plan to meet the expectations of the North
Carolina Brownfields Program for site environmental assessment prior to redevelopment and re-use.

2 BACKGROUND
2.1 Site History
A Phase I Environmental Site Assessment (ESA) was conducted by Excel Civil and Environmental Associates,
PLLC (Excel) and reported on July 22, 2013. The Phase I ESA provides site and vicinity history with respect to
environmental conditions. The original Chronicle Mill building has a 1901 construction date according to Gaston
County Tax records. Various additional buildings were added either in direct connection to the original mill or as
outbuildings from approximately the 1920s through 1978. The site operated as a cotton yarn textile mill, including
carding, roving, spinning, and winding, with fire insurance map information also indicating finishing on the second
floor. Cardno’s experience with spinning mills is that finishing would not have included high volume use of
hazardous fluids common to fabric finishing at other textile facilities. At Chronicle Mill, the indication of finishing on
the second floor would also have reduced the potential for releases to the subsurface. The mill did have a machine
shop and mechanical rooms that housed chillers and air handlers, and both of these areas were on the south-
central part of the main mill building. Transformers were also located on-site to the immediate south of the main
building and at a power substation in an area several hundred feet to the southwest of the building. Previous
environmental due diligence by Excel observed surface staining on a concrete generator pad at the building
exterior adjacent to the machine shop. The last mill operator, R.L. Stowe Mills, Inc., closed operations in 2009.
2.2 Site Vicinity Land Use
The site lies on the south side of Catawba Street, and the north side of the street has residential and commercial
properties, including Allied Fabric (Fun-Tees), which formerly operated as Unocal and Chevron retail fuel sales,
and is an open petroleum underground storage tank (UST) incident (#14196). The Allied Fabric site is north of the
western side of the site. The UST incident is classified as intermediate risk based on groundwater impact
exceeding North Carolina Gross Contamination Levels (GCLs). The incident progressed from assessment through
remediation with total fluids pumping and treatment, which operated for approximately one year in 2007 and 2008.
Monitored natural attenuation (MNA) for the former Unocal/Chevron UST incident is currently on-going, with the
most recent monitoring having been reported in June 2014 by AECOM.
The former leaking UST site is apparently side to upgradient with respect to groundwater flow from the site.
However, data collected during a Cardno file review at the North Carolina Department of Environment and Natural
Resources (NCDENR) Mooresville Regional Office show that incident monitoring wells at the Chronicle Mill site
(UMW-9 and UMW-11) have minimal to non-detectable petroleum impact. Figure 3 provides an estimated extent
of petroleum impact from the former Unocal/Chevron incident. Based on the analytical data, Cardno concluded
that this release incident has not significant impacted the subject site.
Properties to the northeast and east of the site are primarily residential and side to downgradient with the limited
commercial use having no indications of sources of environmental impact, and areas to the south of the site include
railroad right-of-way followed by abandoned and mostly demolished industrial facilities. Topographic conditions
indicate that areas to the south would be downgradient. A rail siding is located to the west of the property with
mostly residential property beyond. The headwaters of a creek are also located to the west of the site. Previous
environmental investigations found Sanborn Fire Insurance Maps from 1922 and 1938 which showed former
gasoline tanks on the property west of the site across the creek. Chronicle Mill monitoring well data do not suggest
this site is a source of petroleum impacts on the site property, and the creek between the property to the west and
the site would likely prevent migration to the site. Natural bioremedial effects would also likely have attenuated
impact in the approximately 75 year interim.
2.3 Previous Environmental Assessment and Remediation
Environmental assessment and remediation have been conducted at the site as documented in the Phase I
Environmental Site Assessment Report dated July 22, 2013, which was conducted by Excel. The work began as
non-invasive due diligence using historical and regulatory sources, in early 2012, and identified recognized
Report of Findings – North Carolina Brownfields Program Former Chronicle Mill Facility
July 21, 2015 Cardno 3
environmental conditions (RECs), including the concrete pad staining near the machine shop, groundwater impact
by tetrachloroethene (PCE) and naphthalene that was detected in the Unocal/Chevron monitoring well network,
and transformers at the rear of the mill building and in the power substation on the southwestern part of the site.
The RECs were further investigated by installation and analytical testing using soil borings and monitoring wells,
which was conducted during 2012.
The results of soil assessment activities indicated two primary areas of soil impacted by petroleum, one at the
location of stained soil near the machine shop and former generator, and the second at the location of a former
power substation in the southwestern part of the site. These areas of impacted soil were remediated by excavation
with off-site disposal. Excavation and disposal conducted in March through May 2012 included 72.95 tons of
petroleum impacted soil from the area of stained soil near the machine shop and former generator, and excavation
and disposal in January 2013 of 23.62 tons of petroleum impacted soil from the area of a former power substation.
Post-excavation soil samples were collected in the excavation area near the former machine shop and generator
for analysis of gasoline and diesel range total petroleum hydrocarbons (TPH). The results of the laboratory
analyses for the final post-excavation samples indicated no exceedences of the NCDENR Action Level for TPH of
10 milligrams per kilogram (mg/kg). Post-excavation soil samples were collected from the excavated area near
the former power substation for analysis by Environmental Protection Agency (EPA) Method 8260, EPA Method
8270, Massachusetts Department of Environmental Protection (MADEP) Volatile Petroleum Hydrocarbons (VPH)
Method, and MADEP Extractable Petroleum Hydrocarbons (EPH) Method. The results of the laboratory analyses
indicated no exceedences of NCDENR UST Section Maximum Soil Contaminant Concentrations (MSCCs). Note
that samples were also collected for analysis of polychlorinated biphenyls (PCBs) during the initial assessment in
the former power substation area, and no PCBs were detected.
Note that Cardno also compared the post-excavation analytical data to the latest NCDENR Inactive Hazardous
Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs) and identified exceedences of PSRGs in three
post-excavation samples. Sample “South” contained benzo(b)fluoranthene at a concentration above the
Residential PSRG, sample “East” contained benzo(b)fluoranthene at a concentration above the Residential and
Protection of Groundwater PSRGs, and sample “North” contained C9-C22 aromatics (referred to as TPH - Medium
Aromatics in the PSRG table) above the Residential PSRG. Exceedances of Protection of Groundwater PSRGs
indicate a potential for leaching to groundwater; however, leaching to groundwater is not considered a significant
concern since the Brownfields Agreement is expected to incorporate a groundwater use restriction and nearby
MW-7 contained no detectable petroleum impact. With regard to the Residential PSRG exceedances, Cardno
performed risk assessment calculations which show that the cumulative carcinogenic risk and hazard index for the
combined constituents of concern in samples “North” and “East” do not exceed the levels considered acceptable
by the Brownfields Program for a future resident (cumulative carcinogenic risk of 10-4 and hazard index of 1).
Copies of these calculations can be provided to the Brownfields Program upon request.
A detection of one petroleum constituent in soil, naphthalene, remains above the UST Section MSCCs and IHSB
PSRGs for protection of groundwater use, in the area north of the main mill building as encountered in the boring
for MW-1. The naphthalene in soil at MW-1 has no known or suspected source associated with the former mill
operations. Regardless, the concentration detected was below Residential and Industrial MSCCs and PSRGs and
therefore poses no direct-contact risk during site redevelopment and reuse. The exceedance indicates a potential
for leaching to groundwater; however, groundwater samples from well MW-1 did not contain detectable
naphthalene, which indicates significant leaching to groundwater is not occurring. In addition, leaching to
groundwater is not considered a significant concern since the Brownfields Agreement is expected to incorporate
a groundwater use restriction. Figure 4 documents the previous soil assessment and remediation activities at the
site.
An area of groundwater impact by PCE and naphthalene is documented to the south of the main mill building,
based on assessment using one temporary and seven permanent monitoring wells installed by Excel during 2012
and based on information from a former Unocal/Chevron well, MW-11, on the south-central part of the site. The
extent of the impacted groundwater is limited to the site and to the rights-of-way for Back Street and Short Street
to the immediate southeast of the site, based on testing of the site monitoring well network. The maximum
concentrations of PCE and naphthalene have been documented at 59 micrograms per liter (ug/L) and 47 ug/L,
Report of Findings – North Carolina Brownfields Program Former Chronicle Mill Facility

respectively, at MW-4. The North Carolina 2L Groundwater Standards (Title 15A, NCAC Subchapter 2L, Part
.0202) for PCE and naphthalene are 0.7 ug/L and 6 ug/L, respectively. Other constituents related to the
degradation of PCE were encountered in the groundwater dataset, but none of the concentrations exceeded their
respective 2L Standards. Possible sources for groundwater impacts could include the machine shop or mechanical
areas in the south central part of the main mill building, or general industrial use and materials management at the
rear of the facility along a former rail siding that served the rear of the mill for an extended period. As discussed
further below, soil gas sampling indicated higher concentrations outside the building versus inside the building,
which suggests an exterior source. Figure 3 shows the estimated lateral extent of impacts to groundwater
associated with releases at the subject site and the former Unocal/Chevron petroleum release incident.
A former water supply well in the south-central part of the site was tested for volatile organic compounds (VOCs),
and no detections of VOCs were encountered. The water supply well was abandoned after sampling. The water
supply well was reportedly 490 feet deep with an 8-inch diameter casing.
The assessment concluded in July 2013, with soil gas samples being collected and analyzed from two locations.
One sample was collected in the area of highest groundwater impacts near well MW-4 (SSGS-1). The second
sample was collected beneath the south-central part of the mill building in the former machine shop area (SSGS-
2). Both samples were collected at a depth of 2 feet below ground surface (ft bgs). The results of the laboratory
analyses indicated concentrations of PCE and/or trichloroethylene (TCE) above the NCDENR, Division of Waste
Management (DWM), Residential Soil Gas Screening Levels (SGSLs). Concentrations did not exceed the DWM
Non-Residential SGSLs. Some concerns exist regarding the protocol for the prior soil gas sampling. Exterior soil
gas samples collected at a depth of less than 5 ft bgs are generally considered unreliable due to the potential for
infiltration of outdoor air. In addition, no leak testing was done during the prior sampling. Due to these concerns,
additional soil gas sampling was conducted as discussed in Section 5.

3 SITE TOPOGRAPHY, GEOLOGY, AND
HYDROGEOLOGY
3.1 Topography
The site lies on a hill side between a ridgeline approximately 1,000 feet to the north and an unnamed tributary of
the Catawba River approximately 500 feet to the south. The United States Geological Survey (USGS) 7.5-Minute
Series Topographic Map, Belmont, North Carolina Quadrangle, dated 1997, shows that the elevation of the site
ranges from approximately is approximately 670 feet above mean sea level (ft MSL) along Catawba Street, to
approximately 640 ft MSL along the southern property boundary. Additionally, a valley extends along the western
side of the site, so that western parts of the site slope downward to the west, and a gentler slope from the south
central part of the site extends downward to the southeast. Modifications of the site topography may also have
been conducted to accommodate construction of the mill and nearby roadways, so that the existing site and vicinity
topography may vary from the pre-development topography.
3.2 Geology
According to the Geologic Map of North Carolina, produced by the State of North Carolina in 1985, the site lies in the Charlotte Belt of the Piedmont Physiographic Province of North Carolina. The specific rock type beneath the
site is a metamorphosed quartz diorite, which would likely appear similar and slightly darker than granite, with foliation or other features related to the post-emplacement metamorphism. The shallow subsurface in most areas of the Piedmont contains residual soil overburden, including structure-free residuum, saprolite, and partially weathered rock (PWR) that derive from in-place weathering of the crystalline bedrock. Occasional areas containing
recent deposits of alluvium in the uppermost subsurface are found near streams and rivers. Saprolite and PWR typically contain some relict structures from the original rock material. Depth to rock in the Piedmont typically
ranges from ground surface at occasional outcrops to depths of more than 100 ft bgs in areas of easily weathered rock.
Information on depth to rock was not available for the site, except that the monitoring wells were installed to 30 ft bgs without encountering bedrock. A deep monitoring well was installed during assessment at the nearby former Unocal/Chevron incident site, and no bedrock was encountered in that well, which has a total depth of 60 ft bgs.
Shallow soil at the site and vicinity has been described as silty clay or clayey silt with variable sand content.
3.3 Hydrogeology
The shallow aquifer occurrence varies in depth from ground surface at springs, creeks, and rivers to as deep as
50 feet or more beneath upland surfaces in some parts of the Piedmont. Water in the alluvium or unconsolidated residual material, including saprolite and PWR, usually behaves as an unconfined, or water table, aquifer and will
yield water with head elevation equivalent to the first elevation where water was encountered. Permeability varies with lithology and is typically relatively low in residual soils, with higher permeability in saprolite or PWR due to
relict rock texture and variable susceptibility to weathering exhibited by different minerals in the rock. Groundwater flow in residual soils or alluvium is usually in rough concurrence with local topographic conditions and is toward
local drainage features.
Shallow groundwater flow at the site has been documented to flow in a quasi-radial pattern from southward on the western part of the site to southeastward or eastward on the central and eastern parts of the site, respectively.
That is, upgradient locations are generally to the north of the site; side gradient locations are to the west and northeast of the site, and downgradient locations are to the southeast and south of the site. Horizontal gradients
range from a slope on the eastern part of the site at approximately 0.025, which would be considered a moderate gradient, to a slope on the western part of the site of approximately 0.012, which would be considered a moderately
low gradient. Depth to groundwater is approximately 20 to 25 ft bgs, depending on location beneath the site.
The bedrock fractures or other planar features generally constitute the bedrock aquifer, with the surrounding rock material being effectively impermeable. Along with fractures, contacts between rock bodies probably constitute
zones of significant groundwater occurrence in the bedrock. The surrounding material and overlying residuum tend
Report of Findings – North Carolina Brownfields Program Former Chronicle Mill Facility
July 21, 2015 Cardno 6
to make the bedrock aquifer a semi-confined aquifer. That is, the overlying water and soil weight normally results in pressure that causes water in a borehole which intersects a fracture or other feature to rise above the elevation
of the fracture or feature. Such features may not occur on predicable trends, at the same elevations, or even be present or directly connected in separate boreholes. In areas adjacent to creeks the bedrock groundwater
generally discharges to the residuum or alluvium and then into the surface water. In upland areas away from surface water drainages, the bedrock aquifer is generally recharged by downward infiltration of residuum or alluvial
aquifer water at locations where fractures intersect the bedrock surface.

4 REDEVELOPMENT PLAN AND DATA GAPS
Representatives of Chronicle Land, Cardno, and the North Carolina Brownfields Program met at the property on
December 12, 2014, to observe the site and discuss the proposed redevelopment plan. The proposed
redevelopment plan based on the data gathered to date is summarized on the plans included in Appendix A. The
site is proposed for mixed-use redevelopment including possible retail, offices, hotel, and civic uses. Residential
units may be constructed on the upper level of the main mill building, but this has not been confirmed. Potential
data gaps related to possible exposure to contamination, as discussed in the Work Plan and its modifications are
summarized below.
4.1 Impacted Soil
Based on the most recent plans, the majority of the site will be covered by building or pavements. Potential green
space is generally limited to selected areas northwest, north, and east of the main mill building, which will include
a possible outdoor amphitheatre northwest of the main mill building, and the area southwest of the site. Based on
the assessment activities conducted to date, impacted soil does not appear likely to pose a direct-contact risk in
the proposed green space areas. As documented in Section 3, remaining impacted soil in known source areas at
the site does not exceed the levels considered acceptable for residential use. In addition, no potential sources of
shallow impacted soils have been identified in the green space areas which require further investigation. Therefore,
no additional soil sampling is recommended to evaluate direct-contact risks in the proposed green space areas.

Proposed grading plans and the need for appropriate management of impacted soil during grading were also
discussed during the December 2014 on-site meeting. Areas where soil will be cut during grading activities are
expected to be limited to the area directly south of the main building near the former rail spur. Impacted soil may
be present in this area due to operations associated with rail spur. Therefore, the Work Plan proposed soil sampling
in this area. The results of the soil sampling completed in accordance with the approved Work Plan are
documented in Section 5.2.
4.2 Impacted Groundwater
Assessment of impacted groundwater was completed during historical investigations. Although groundwater
impacts are confirmed above North Carolina 2L Groundwater Standards, the property is connected to the public
water service. Cardno anticipates that the Brownfields Agreement will include a groundwater use restriction to
prevent exposure to impacted groundwater. Therefore, no groundwater sampling was proposed in the Work Plan
or conducted during the recent site investigation.
4.3 Vapor Intrusion
Vapor intrusion sampling was completed during the historical assessment activities. However, some concerns
exist regarding the reliability of the data. Therefore, the Work Plan proposed additional vapor intrusion sampling.
The Work Plan proposed collection of soil gas samples from existing monitoring wells MW-3 and MW-4, as well
as one proposed new sub-slab soil gas monitoring point to be installed inside the former machine shop area of the
building. Upon review of the Work Plan, Tony Duque with the Brownfields Program requested changes to the
scope of work in an email dated June 9, 2015. Based on the email, the Brownfields Program did not approve
collection of soil gas samples from monitoring wells MW-3 and MW-4. In lieu of these samples, the Brownfields
Program requested installation and sampling of two additional soil gas monitoring points, one installed
approximately 60 feet north and 80 feet east of MW-4 and the second installed approximately 60 feet north and
80 feet west of MW-4. The results of the vapor intrusion sampling completed in accordance with the Work Plan
and NCDENR amendments to the Work Plan are documented in Section 5.3.

5 SITE INVESTIGATION SCOPE
5.1 Preliminary Activities
Prior to commencing the drilling and sampling activities, Cardno notified One-Call of North Carolina to identify
public utilities at the site. Cardno prepared a site-specific Health and Safety Plan for use by Cardno staff and
subcontractors in accordance with the Occupational Safety and Health Administration (29 Code of Federal
Regulations 1910.120) requirements to address the potential physical and chemical exposure risks associated
with the field environmental sampling activities. Cardno conducted a kick-off meeting prior to mobilization to
discuss scope, stakeholder considerations, and safety. A safety meeting was also conducted at the site prior to
work to assure proper preparation for and personnel notification of potential site hazards.
5.2 Soil Sampling Activities
Soils in the area south of the central part of the former mill building are slated for grading lower to expose part of
the ground floor of the mill on the south side. To evaluate whether soils in this area contain impact associated with
the nearby former rail spur, the Brownfields Program personnel requested composite sampling from several
locations at 1.5 to 2.0 ft bgs. Due to the presence of concrete, each location was cored using an impact hammer
prior to drilling. A total of six borings (borings SB-1 through SB-6) were drilled in a roughly linear arrangement, as
shown on Figure 5. Samples from 1.5 to 2.0 ft bgs from borings SB-1, SB-2 and SB-3 were combined to create
composite sample CS-2. Samples from 1.5 to 2.0 ft bgs from borings SB-4, SB-5 and SB-6 were combined to
create composite sample CS-1.
Each discrete sample was collected using a pre-cleaned hand auger that was cleaned between boring locations
using a tap water and Alconox wash, a tap water rinse, an isopropanol rinse and air dried before re-use. The
technician wore disposable Nitrile gloves which were changed between locations and tasks. Compositing was
performed quickly to minimize vapor off-gassing.
As each soil boring was advanced, duplicates of the interval used for composite sampling were collected into
resealable plastic bags for field screening of total organic vapors utilizing a photoionization detector (PID) that was
calibrated prior to use. The soil samples were also observed for visual evidence of environmental impact and
logged according to the Unified Soil Classification System. Documentation of field observations was collected in a
field log book. In addition to the quality assurance efforts outlined herein, the work was conducted in general
conformance with the EPA Field Branches Quality Management Plan, dated May 8, 2009, and Field Branches
Quality Policy, dated April 17, 2009. Boring logs are included in Appendix B.
The samples were collected into certified clean, properly prepared sample containers; placed on ice under formal
chain-of-custody; and transported to a North Carolina-accredited analytical laboratory. The composite samples
were analyzed for VOCs by EPA Method 8260B, and semivolatile organic compounds (SVOCs) by EPA Method
8270C. Results of the soil analytical testing are provided in Table 1 and indicated on Figure 5.

5.3 Vapor Intrusion Sampling Activities
Investigation was performed to evaluate the risk associated with potential vapor intrusion into existing or future
structures at the site. The investigation was performed in general accordance with the procedures detailed in the
NCDENR DWM VI Guidance dated April 2014. Per the approved Work Plan and NCDENR amendments to the
Work Plan, the vapor intrusion sampling scope of work included installation and sampling of three soil gas
monitoring points, SGMP-1, SGMPO-2 and SGMP-3, each located within the footprint of existing millworks building
as shown on Figure 6. Soil gas sample locations SGMP-2 and SGMP-3 were located in areas of the building
where a concrete slab was present, and therefore each soil gas sample was collected approximately 6-inches
below the existing concrete slab. Soil gas sample location SGMP-1 was located in an area of the building that had
exposed bare ground, therefore the soil gas sample from this location was collected at a depth of approximately
six to eight ft bgs. This modification to the proposed scope of work was made due to concerns with infiltration of
air from the ground surface at the sampling location due to the lack of surface cover. In the absence of surface
cover, most vapor intrusion guidance recommends collection of samples at a depth of at least five ft bgs due to
this concern. . Details regarding the installation and sampling protocol are provided as follows:
 Sub-slab soil gas points SGMP-2 and SGMP-3 were constructed by drilling a hole through the floor slab
using an impact hammer. The boring was then advanced to a depth approximately 6 inches below the
floor slab. The soil gas point was installed with a porous air stone implant at the base of the boring
connected to the surface with ¼-inch diameter Teflon tubing. Filter sand was placed in the annular space
at the sampling depth, and then bentonite/grout slurry was used to seal the annular space to the ground
surface.
 Soil gas point SGMP-1 was constructed by drilling a boring to a depth of approximately six to eight ft bgs
using a hand auger. The soil gas point was installed with a porous air stone implant at the base of the
boring connected to the surface with ¼-inch diameter Teflon tubing. Filter sand was placed in the annular
space at the sampling depth, and then bentonite/grout slurry was used to seal the annular space to the
ground surface.
 Prior to sampling at each location, a shut-in test on the sampling line was conducted to check the
connections by applying a vacuum pressure to the line and observing for any decrease in pressure. Three
tubing volumes were purged using a disposable syringe at a purge rate of less than 200 mL/min. Vacuum
was monitoring during purging and was maintained at less than 100 in H2O.
 Helium gas was used for leak testing. To complete the leak test, a temporary shroud was constructed over
the sampling point. Helium gas was then injected into the shroud. Following purging, a gas sample was
collected from the sampling point in a Tedlar® bag, and helium concentrations were measured in the
sample using a field helium meter. The sampling points are typically considered valid when helium
concentrations in the sample are less than 10 percent of helium concentrations in the shroud. The results
of the leak testing at the subject site indicated no detectable helium concentrations in the samples;
therefore, the sampling points were deemed valid.
 Following purging and leak testing, samples were collected at each location in individually-certified Summa
canisters. The samples were then transported to a North Carolina-accredited analytical laboratory under
formal chain-of-custody for laboratory analysis.
Per recommendations in the DWM VI Guidance and as specified in the approved Work Plan, the constituents of
concern included in the EPA Method TO-15 analysis were limited to the primary constituents detected in soil and
groundwater samples at the site, plus associated breakdown products. Per this protocol, each sample was
analyzed for PCE, TCE, cis-1,2-dichloroethylene (cis-1,2-DCE), trans-1,2-dichloroethylene (trans-1,2-DCE), vinyl
chloride, and naphthalene by EPA Method TO-15. In addition, based on TPH detections in soil, samples were
analyzed for aromatic and aliphatic carbon fractions classes by Massachusetts Department of Environmental
Protection (MADEP) Air-Phase Petroleum Hydrocarbons (APH) Method. The results of the soil gas sampling are
provided in Table 2 and indicated on Figure 6.

6 RESULTS
6.1 Soil Analytical Results
No VOC or SVOC constituents above laboratory detection limits were reported in either of the composite soil
samples collected in the area south of the central part of the former mill building. Table 1 provides a summary of
VOC and SVOC soil analytical data. Laboratory analytical reports are included in Appendix C.
6.2 Soil Gas Analytical Results
The results of the laboratory analyses for the June 2015 soil gas sampling indicated detectable concentrations of
PCE, TPH C5-C8 aliphatics, and TPH C9-C12 aliphatics. As discussed in the Work Plan, the prior soil gas data is
not considered entirely reliable due to questionable sampling protocol, but disregarding the data entirely also
seems unwise. Therefore, the data was evaluated in conjunction with the recent soil gas sampling data, but the
June 2015 sampling results are considered more reliable than the historical sampling results. Constituents of
concern detected in the historical samples include cis-1,2-DCE, TCE, and PCE. Recent and historical soil gas
analytical results are summarized in Table 2. Laboratory analytical reports are included in Appendix C.
The soil gas analytical results were initially compared to the DWM Residential and Non-Residential SGSLs. The
results of this comparison indicated concentrations of PCE above the Residential SGSL in recent sample SGMP-
2 and historical samples SSGS-1 and SSGS-2. TCE was also detected above the Residential SGSL in historical
sample SSGS-1. The DWM has not established SGSLs for TPH. However, the Environmental Protection Agency
(EPA) has established Regional Screening Levels (RSLs) for TPH. The EPA RSLs are also the basis for the DWM
SGSLs. Using a method similar to that used by NCDENR to develop DWM SGSLs, Cardno calculated screening
levels for TPH carbon fraction classes using the EPA RSLs as the basis. To perform this calculation, EPA RSLs
for indoor air were determined for residential and non-residential land use based on the lower of a carcinogenic
risk of 10-5 or hazard quotient of 0.2. These indoor air screening levels were then divided by an attenuation factor
of 0.03 for residential land use and 0.01 for non-residential land use to calculate soil gas screening levels.
Comparison of detected TPH concentrations to the calculated screening levels indicated exceedences for TPH
C9-C12 aliphatics for the residential scenario. None of the detected concentrations exceeded Non-Residential
SGSLs or the calculated TPH screening levels for a non-residential scenario. Table 2 shows the screening levels
used in comparison to detected concentrations.
Since some individual constituents were identified above Residential SGSLs, Cardno performed calculations to
evaluate cumulative risk for the combined constituents of concern for each sample. The Risk Assessment Toolkit
(Toolkit) developed by the North Carolina Dry-cleaning Solvent Cleanup Act (DSCA) Program was used to
complete the evaluation. The Toolkit includes an excel-based calculator that calculates cumulative risk based on
soil gas concentrations in accordance with NC DWM procedures. Soil gas concentrations are entered into the
Toolkit, and then the Toolkit calculates predicted indoor air concentrations by multiplying soil gas concentrations
by an attenuation factor. The DWM approved attenuation factors of 0.03 for residential land use and 0.01 for non-
residential land use are used. Cumulative carcinogenic risk and hazard quotient for the combined constituents of
concern are then calculated by comparing the predicted indoor air concentrations to screening levels and applying
a simple sum of ratios approach. Refer to the NC DSCA Program Risk Assessment Guidance (RAGS) dated May
2015 for additional details regarding the specific calculations performed by the Toolkit. The risk calculation
spreadsheets from the Toolkit are included in Appendix D. Cumulative risk values for each soil gas sample are
summarized in Table 3.

The Brownfields Program requires mitigation for sites showing exceedences of a carcinogenic risk limit of 10-4 and
hazard index limit of 1. The results of the risk calculations for the subject site indicated exceedences of these
levels for residential land-use in only one sample. Historical sample SSGS-1 indicated a hazard index of 2.11.
However, this sample was collected outside of the existing building and in an area where no building construction
is proposed. All of the samples collected inside the existing building showed risk values substantially below
acceptable levels. Furthermore, no exceedences of acceptable risk levels for a non-residential worker were
identified, and ground-floor building occupants will be non-residential. Based on these data, Cardno concludes
that the soil gas concentrations do not pose an unacceptable risk to building occupants and no mitigation of vapor
intrusion is warranted as part of the proposed redevelopment.

7 Conclusions and Recommendations
Cardno has completed soil and soil gas sampling at the former Chronicle Mill site in accordance with the Work
Plan dated February 9, 2015, which was approved by the Brownfields Program with modifications in an email
dated June 9, 2015. The purpose of the sampling was to fulfil data gaps identified based on review of historical
assessment data. A summary of Cardno’s conclusions and recommendations based on the recent and historical
assessment data is provided below:

 Previous soil assessment data indicated two areas of impacted soil, one at the location of stained soil near
the machine shop and former generator, and the second at the location of a former power substation in
the southwestern part of the site. These areas of impacted soil were remediated by excavation with off-
site disposal. The only data gap identified based on review of historical soil assessment data was a need
to evaluate whether impacted soil exists in areas that will be disturbed during grading associated with the
site redevelopment. The area where soil will be cut during grading activities is expected to be limited to
the area directly south of the main building near the former rail spur. Therefore, the recent investigation
included advancement of six borings and analysis of two composite soil samples from this area. Laboratory
analyses of the soil samples indicated no detectable VOCs or SVOCs. Based on these data, impacted
soil is not expected to be disturbed during grading and protective measures or contaminated soil disposal
are not expected to be required.

 Previous groundwater assessment data indicated a plume of groundwater impacted by PCE and
naphthalene at concentrations above NC 2L Groundwater Standards. However, the property is connected
to the public water service and Cardno anticipates that the Brownfields Agreement will include a
groundwater use restriction to prevent exposure to impacted groundwater. Therefore, no groundwater
sampling conducted during the recent site investigation.

 Soil gas sampling was completed during the historical assessment activities to evaluate the potential risk
associated with vapor intrusion. However, some concerns exist regarding the reliability of the data.
Therefore, the Work Plan proposed additional vapor intrusion investigation. In accordance with NCDENR
modifications to the Work Plan, the recent investigation included collection of three soil gas samples. Risk
calculations were performed for both the historical and recent soil gas samples. The results of the sampling
indicated no exceedences of the risk levels considered acceptable by the Brownfields Program for
residential land use inside of the building. One exceedence was identified in a historical exterior soil gas
sample; however, this exceedance is not considered a concern since no building is present in this area
nor will a building be constructed as part of the redevelopment. Furthermore, no exceedences of
acceptable risk levels for a non-residential worker were identified, and ground-floor building occupants will
be non-residential. Based on these data, Cardno concludes that the soil gas concentrations do not pose
an unacceptable risk to building occupants and no mitigation of vapor intrusion is warranted as part of the
proposed redevelopment.

8 LIMITATIONS
Our professional services have been performed, our findings obtained and our recommendations prepared in
accordance with customary principles and practices in the fields of environmental science and engineering in the
State of North Carolina. This warranty is in lieu of all other warranties either expressed or implied. Cardno is not
responsible for the independent conclusions, opinions or recommendations made by others based on the results
and designs presented in this report. The passage of time may result in a change in the environmental conditions
at this site and surrounding properties. This report does not warrant against future operations or conditions, nor
does it warrant operations or conditions present of a type or at a location not investigated.

This subsurface investigation is limited in that results were obtained only for those areas investigated. In addition,
the final depths of the advanced soil borings were dictated by proposal as agreed by the client/independent client
advisors and site-specific subsurface conditions. Cardno does not warrant that all areas of the site are free and
clear of contamination, or that all contamination has been identified by this investigation. All investigations are
limited in their scopes and results, and should only be interpreted in the context from which they were designed.

No investigation can absolutely rule out the existence or degree of any hazardous materials or petroleum products
at a given site. If a higher level of confidence were required than can be defined by this scope of work, then
additional investigation would, of course, be required. Cardno accepts no liability arising from environmental impact
to, of from, the site, regardless of the date of impact occurrence or findings.
