B. SITE HISTORY
The site is located at 309 & 310 West Crowell Street in Monroe, Union County, North Carolina.
Previous submissions to the North Carolina Department of Environmental Quality (NCDEQ)-
Brownfields Redevelopment Section (BRS) pertaining to assessment(s) at the subject site can be
viewed at the NCDEQ-BRS Office.
The Brownfields property consisted of six (6) parcels totaling approximately 13.26 acres. Please
note that at the time the BFA was recorded (June 2017) the following parcels were listed as part
of the site:
Parcel Number Address(es) Size (acres)
09232254 500 West Jefferson St 1.271
09232242 503 West Jefferson St
500 West Franklin St 0.57
09232255 316 West Jefferson St 0.139
09232256 309 West Crowell St
1501 N Charlotte Ave 2.182
09232260 310 West Crowell St 8.49
09232257 502 West Crowell St 0.614

Although a date is not provided via the Union County Tax Assessor’s Office, Parcel 09232260
has since been subdivided and the updated acreage for the aforementioned parcel is 5.89 acres,
which houses the new Monroe Police Department located at 450 West Crowell Street. East of
Parcel Number 09232260, is the subdivided 2.60-acre parcel identified as Parcel Number
09232260A which is owned, as other parcels mentioned above, by the City of Monroe. For
purposes of this final grade sampling plan, with the exception of the renovated Bazemore Active
Adult Center (located at 500 West Jefferson Street/Parcel Number 09232254) which followed a
separate EMP during renovations/updates, the following areas will be assessed:
• Parcel Number 09232260 (5.89 acres): Police Department @ 450 W Crowell St
• Parcel Number 09232255 (0.139 acres): New Parking lot @ former 316 W Jefferson St
• Parcel Number 09232256 (2.182 acres): New Parking Lot @ former 309 W Crowell St and
1501 N Charlotte Ave
• Parcel Number 09232242 (0.57 acres): New Parking Lot @ former 503 W Jefferson St
and 500 W Franklin St

See attached Figure 1 depicting the area to be assessed in the current Final Grade Sampling
Plan. Final grade sampling for the remaining areas (Parcel Number 09232260A; the proposed
site of the new Monroe Fire Department and Parcel Number 09232257; undeveloped) on the
Brownfields Property will be addressed at a later date under separate cover.

Historically, the Brownfields property is the site of the former Scott Aviation manufacturing facility
and former Monroe Enquirer Journal (MEJ) newspaper printing and office building. Various
environmental assessments have been conducted dating back to the 1990s on the site or portions
thereof. Soil and ground water at the site is primarily contaminated with chlorinated solvents and
other volatile organic compounds.
The former structures associated with Scott Aviation were demolished in 2013 down to the
foundations, which were removed in 2020. Based on AECOM Technical Services of North
Carolina, Inc. (AECOM)’s pre-characterization of soils conducted in 2019, a total of 1,785 cubic
yards (2,600 tons) of contaminated soil was removed from the site in 2020.
Parcel Number 09232260 has been redeveloped as the Monroe Police Department associated
parking area. In addition, parking lot improvements have been completed on Parcel Numbers
09232255, 09232256 and 09232242. The City of Monroe is responsible for the areas surrounding
the parking lot (common areas and landscaping).
A general Environmental Management Plan (EMP) was submitted by Resolve to the NCDEQ-
BRS on January 6, 2020 and subsequently approved on January 21, 2020. A Vapor Intrusion
Mitigation Plan (VIMP) for the new police department structure was submitted to the NCDEQ-
BRS on February 17, 2021 and subsequently approved on March 5, 2021. In accordance with the
NCDEQ-approved EMP dated January 21, 2020, Resolve presents this sampling plan for final
grade soils at the subject site. The proposed areas of sampling are within the common areas and
landscaping surrounding the completed police department structure and completed parking lots.
All soil disturbance (including that for utility work) has been completed in its entirety in the areas
where soil sampling is proposed. Development at this portion of the Brownfields Property is
complete.
C. SAMPLING PLAN

The final grade soil sampling plan will be conducted per the NCDEQ-approved EMP which
consists of collecting soil samples from exposed native soils (i.e. soil that will not be under
buildings or permanent hardscape).

D. SCOPE OF WORK
The following work scope is based upon Resolve’s EMP dated January 21, 2020. A Site-Specific
Health and Safety Plan will be prepared by Resolve in accordance with 29 CFR 1910.120
(HAZWOPER). All on-site Resolve personnel will be current with HAZWOPER training. The
Health and Safety Plan will be present on site during all field activities. The scope of work for the
additional assessment is detailed below.
1. Resolve recently conducted a site reconnaissance and proposes to collect four (4)
composite samples (consisting of three (3) primary samples in Area 1 and five (5) primary
samples in Areas 2 and 3) of exposed native soils at the subject property. The soil
samples will be collected and analyzed for the appropriate methods. The locations of the

6

exposed, native soil proposed to be sampled are shown on Figure 1. A summary of the
sample locations and analyses is included in Table 1.
2. Up to fourteen (14) soil borings will be installed in the exposed native soils. The borings
will be advanced to 2 feet below grade surface (BGS) using a hand auger. The soil cuttings
will be screened with a PID. A soil sample will be collected from 0-1.0’ interval. A second
soil sample will be collected from the 1.0’-2.0’ interval. The soil samples collected from
each of the shallow sample intervals (~1.0’) from each boring within each Area (see Figure
1) will be field composited (applicable to Area 1, 2 and 3) and submitted to a North Carolina
certified laboratory for analysis of semi-volatile organic compounds (SVOCs) by SW-846
Method 8270D and 8 RCRA metals by Method 6020. The soil samples from the deeper
sampling interval (~2.0’) which exhibit the highest PID reading within each Area, will be
submitted for analyses of volatile organic compounds (VOCs) by SW-846 Method 8260.
3. Upon receipt of the final laboratory analytical report, Resolve will prepare and submit a
final grade soil sampling report.

E. SAMPLING METHODOLGY
Samples will be collected and analyzed in accordance with the NCDEQ, Division of Waste
Management, Inactive Hazardous Sites Program “Guidelines for Assessment and Cleanup”
(October, 2015, revised September 2023) and the US EPA Region 4 Science and Ecosystem
Support Division Guidance.

Soil Sampling: Soil borings will each be initially advanced to a total depth of 2.0 BGS using a hand
auger. A soil sample will be collected from the 0- 1.0’ interval and 1.5’ - 2.0’ feet interval in each
boring. Soils will be screened using a PID. If suspected impacts are observed at or near the
boring spud (visual, olfactory or PID), samples will also be collected from shallower intervals as
warranted including the ground surface.

Four (4) areas will be designated from which soil borings will be installed and soil samples
collected:
Area 1 – Soil borings 1-3
Area 2 – Soil borings 4-8
Area 3 – Soil borings 9-13
Area 4 – Soil boring 14

The proposed locations of the soil borings are shown on Figure 1.

F. LABORATORY ANALYSES
All samples will be collected and immediately placed into laboratory-supplied glassware, placed
on ice and transported to a North Carolina certified laboratory for analyses within 24 hours of
sample collection and within the applicable hold times for each proposed method. The laboratory
will conduct the analyses using Level II QA/QC with method detection limits at or below the

7

applicable NCDEQ reporting requirements. Laboratory results (including J-flags) will be included
in the final laboratory report.
1. Soil will be analyzed for VOCs by SW-846 Method 8260B, SVOCs by SW-846 Method
8270D, and 8 RCRA Metals by EPA Method 6020. If preliminary data results indicate that
a sample could potentially contain impacts that are hazardous (i.e. fail the 20:1 rule), a
TCLP sample will be run for the COC. One additional aliquot from each soil sample will
be collected and submitted to the laboratory to be put on hold for Hexavalent Chromium
analysis (EPA 7199) in the event that it becomes necessary based on the results of the
RCRA analysis.

2. Duplicate Samples
One (1) duplicate sample from a soil sample will be analyzed for VOCs by SW-846 Method
8260B. One (1) duplicate composite sample will be collected and analyzed for SVOCs by
SW-846B Method 8270D and for 8 RCRA Metals by EPA Method 6020.
G. QUALITY ASSURANCE/QUALITY CONTROL
1. Soil Boring Installation
All down-hole drilling equipment (hand auger) will be washed, scrubbed and rinsed prior
to use and between each soil boring installation location.

2. Soil Sampling
Soil samples will be collected using a decontaminated hand auger. All field meters will be
properly calibrated prior to sampling. All sample collection equipment will be
decontaminated prior to use and between sampling locations. Field personnel will collect
each soil sample using a new pair of nitrile gloves.

Samples from each of the fourteen (14) borings will be screened with a PID. The sample
from each Area exhibiting the highest PID reading will be submitted for analysis of VOCs
by SW-846 Method 8260B (Note: the sample collected from Area 4 will be submitted for
analysis of VOCs by SW-846 Method 8260B). Composite samples from each sample
Area (comprised of 3 primary samples in Area 1 and 5 primary samples in Areas 2 and 3)
will be submitted for analyses of SVOCs by SW-846 Method 8270D and 8 RCRA metals
by EPA Method 6020. A reserve sample will be obtained for each primary 8260B sample
and for each composite 8270D and 8 RCRA metals sample to be analyzed by TCLP if
required.

For PID screening of soils to select the 8260B VOC sample per area, samples will be split.
One portion of the sample will be used for PID screening. The other portion of the sample
selected (highest PID reading) will be containerized for submittal to the laboratory. If PID
readings equal 0.0 ppm in all 1.5’-2.0’ sample intervals collected from the borings, a soil
sample will be chosen at random for laboratory analysis of VOCs.

8

For composite sampling, each primary sample will be placed into a decontaminated Pyrex
tray. The material in the tray will be divided into quarters and each quarter mixed
individually. Two quarters will then be mixed to form halves. The halves will be mixed to
form a homogeneous matrix. The composite sample will then be collected from the
homogeneous mix.

The samples will be placed directly into laboratory-supplied sample containers,
immediately placed on ice in a sample cooler and transported to the laboratory in the
manner described above. Proper chain of custody procedures will be maintained at all
times.

3. Duplicates and Trip Blanks
To evaluate laboratory quality control and repeatability, one duplicate soil sample will be
collected and analyzed for VOCs, SVOCs and 8 RCRA metals. One (1) trip blank sample
will accompany the samples during the sampling event.

H. INVESTIGATIVE DERIVED WASTE MANAGEMENT
Soil cuttings from the installation of soil borings will be field screened and/or visually inspected.
If no indications of impact are noted, soils will be used to backfill the soil borings and/or spread
onto the ground in the vicinity of the boring. If field screening and/or visual observations indicate
soils are impacted, impacted soils will be placed into labeled 55-gallon drums and appropriate
samples collected to characterize the soils for proper disposal.

I. REPORTING

All of the results and field data from the assessment activities will be summarized and presented
in a Soil Sampling Report that will include all applicable field data, laboratory analytical results
(including J-flagged or estimated concentrations), tables, figures, NCDEQ risk calculator,
conclusions and recommendations for the site, and will be certified by signature and seal of
Professional Geologist duly licensed in North Carolina.
