JULY 14, 2020 1.0 INTRODUCTION
The North Carolina Department of Transportation (NCDOT) is planning construction
activities and complete parcel acquisition as necessary for the US 70 improvements in New Bern, North Carolina. NCDOT has indicated a site investigation is necessary to determine if underground storage tanks (USTs), contaminated groundwater and/or contaminated soils are present.
2.0 PURPOSE OF INVESTIGATION AND DESCRIPTION CATLIN Engineers and Scientists (CATLIN) was retained by the NCDOT Geotechnical Engineering Unit to provide field investigations concluding with
GeoEnvironmental Phase II Investigation reports for 15 sites. In response to a
request for proposal by Mr. John Pilipchuk, L.G., P.E. dated April 23, 2020 and subsequent work scope discussions with Mr. Gordon Box, L.G., CATLIN submitted a proposal for conducting an investigation at Parcel 175 – Mallard Oil Co., 1230 E US 70 Hwy, along the NCDOT Project “New Bern – US 70, from the Neuse River Bridge
to SR 1124 (Grantham Rd.) – Upgrade Roadway to Freeway and US 70 at Taverna
Way. Convert At-Grade Intersection to Interchange & US 70 at West Thurman Road/East Thurman Road” in New Bern, North Carolina. Figure 1 illustrates the general site location. The NCDOT Conventional Plan Sheet Symbols are provided on Figure 2.

According to NCDOT, complete parcel acquisition may be necessary for the roadway construction (TIP Number U-5173 & R-5777A&B) and specifically at the above referenced parcel (Parcel 175). A site investigation was requested before acquisition and roadway construction. The work scope as requested includes:
• Notify property owners/occupants of schedule and scope of work.
• Research the past use and/or possible releases at each site. Determine possible contaminants that may be encountered. Obtain North Carolina
Department of Environmental Quality (NCDEQ) records and include in final report, if applicable.
• Locate all USTs, determine approximate size and contents (if any) and indicate locations(s) on MicroStation file.
• Determine if contaminated soils are present.
• Advance borings to water table.

• Test soil for contaminants relevant to the site’s past use and/or possible release(s). For petroleum contaminants, Ultraviolet Fluorescence (UVF)
analysis is the preferred testing method.
• If an Incident has been assigned by NCDEQ to a parcel, or if contamination has been observed, document the condition of groundwater utilizing existing data, if sufficient, or by collecting a sample from a single temporary
monitoring well. Each groundwater sample should be located with an emphasis on the vicinity of proposed drainage features or other anticipated excavation.
• Include (as a standard delivery item) the RED Lab graphs in reports and
send the GeoEnvironmental Section a copy of the RED Lab Excel file(s).
• If soil and groundwater contamination are evident, estimate the quantity of impacted soils and indicate the approximate area of soil and groundwater contamination on report figures and on a XXXXX_geo_env.dgn file.
• Provide a MicroStation file with the location of soil borings, USTs, soil contamination and monitoring wells.
• Prepare a report for each site (15) including field activities, findings, and
recommendations for each site and submit one electronic copy of each to the NCDOT GeoEnvironmental Section.
• Coordinate with Right of Way (ROW) Office and/or their consultant and/or property owner/tenant to attain access to the interior of onsite buildings as
applicable.
• If there is a building on site, then comment on the function and contents regardless of its location with respect to the proposed ROW/Easement/study area. Comment if it lies within a proposed easement or ROW. If it lies in
ROW or easement, then conduct observations to inform remediation, if
required. Determine if hydraulic lifts with inground components are on site.
• Sample and gauge existing monitoring well(s) if monitoring wells and/or remediation system and groundwater monitoring wells are on site. Report
well diameter and total depth of well(s), and/or if it has been properly abandoned.
• Advance 10 borings and collect one (1) soil sample from each boring to determine if contaminated soils are present.
• Submit 10 soil samples for UVF analysis.
• Collect one (1) groundwater sample and submit for volatile and semi-volatile organics analyses per Environmental Protection Agency (EPA) Method 625
and Standard Method 6200B.
• Report the depth to groundwater. This report documents our activities and findings at Parcel 175: Mallard Oil Co.,
1230 E US 70 Hwy, New Bern, North Carolina.
3.0 METHODS
Proposed boring/sample locations were discussed and agreed upon before boring
advancement.

CATLIN coordinated geophysical activities with Pyramid Geophysical Services (Pyramid). The geophysical investigation methods and site photographs taken during the geophysical investigation are included in the Pyramid Geophysical
Survey provided in Appendix A.
CATLIN proposed utilizing QROS On-Site Rapid Measurement Techniques and Tools (QED™ Analyzer) by RED Lab to evaluate potential for petroleum and Poly Aromatic Hydrocarbon (PAH) impacts to soil in a cost-effective manner. Soil
samples collected from above the approximate water table depth with total
petroleum hydrocarbon (TPH) concentrations greater than the NCDEQ Action Levels [100 milligrams per kilogram (mg/kg) diesel range organics (DRO) or 50 mg/kg gasoline range organics (GRO)] will be considered contaminated for estimated impacted vadose soil volume calculations.

Contaminated soil volume is estimated from the surface to the water table and/or the midpoint distance between a “clean” sample location and contaminated sample location or the property line/easement.
Soil sample borings advanced during this investigation are identified with “175DPT-”
and numbered sequentially 01 through 10. Soil samples for analysis per QROS QED™ Analyzer are identified by boring number and depth [example: 175DPT-01 (4’)]. Groundwater samples for analysis per EPA Method 625 and Standard Method 6200B are identified by boring number (example: 175DPT-01). CATLIN’s field
activities at the site began on June 3, 2020 and concluded on June 17, 2020.
3.1 FIELD METHODS
All field work was conducted in general accordance with state and federal
guidelines and industry standards.
Underground utility locating was coordinated by CATLIN personnel. The North Carolina One Call Center (NC-1-Call) was contacted for underground utility location. The areas around the proposed boring locations were
checked and underground utilities were indicated by NC-1-Call personnel.
Pyramid also marked private underground utilities and cleared the boring locations. CATLIN personnel gathered subsurface soil data by Direct Push Technology
(DPT) boring advancement using a PowerProbe 9600 (PowerProbe). When
using the PowerProbe, the borings are advanced to depth by static force and a hydraulic percussion hammer. Two and one-quarter inch diameter by four-foot length steel is used as casing. Soil samples are continuously collected in one and one-half inch clear liners. Liners are removed from the casing
and then cut in half longitudinally to allow for visual/manual classification
utilizing the Unified Soil Classification System (USCS). Boring information was recorded on field logs and transferred to boring logs (see Appendix B). Soils were removed from the liner in two (2) foot intervals and placed in sealable polyethylene bags for organic volatile (headspace) analysis (OVA)

utilizing a MiniRAE 3000 Photoionization Detector (PID). The OVA results were documented on field logs and are included on the boring logs in Appendix B. Soil samples were selected and packed in appropriate
glassware for analysis. One (1) soil sample was collected from each soil
boring location. New disposable nitrile gloves were worn during sampling activities. Soils selected for QROS QED™ analysis were placed into new glassware
provided by QROS. All samples were placed on ice in an insulated cooler for
transportation to RED Lab in Wilmington, NC. Sample integrity was maintained by following proper Chain of Custody (COC) procedures. A copy of the COC is provided following the analytical report in Appendix C.
Following boring termination and tooling removal, new one-inch slotted poly
vinyl chloride (PVC) well screen and casing was installed in one (1) borehole. A grab groundwater sample was collected from the temporary well utilizing a peristaltic pump and new polyethylene tubing. Groundwater was pumped directly into laboratory provided glassware. New, disposable nitrile gloves
were worn when handling well material and while collecting the groundwater
sample. The sample was packed on ice in an insulated cooler for transportation to Environmental Conservation Laboratories, Inc. (ENCO) in Cary, North Carolina. Sample integrity was maintained by following proper COC procedures (see Appendix C).

The PVC materials were subsequently removed from the boring. Boreholes were abandoned to the surface in grassy areas and just below existing asphalt in asphalt areas using three-eighth inch bentonite chips. Bentonite and water were poured into the borehole simultaneously to facilitate
hydration. Boreholes in asphalt were finished with asphalt patch to the
surface. Complete well construction and well abandonment records are provided in Appendix B. 3.2 ANALYTICAL TESTING

The QROS QED™ Analyzer methods have been approved by the NCDEQ for petroleum contamination determination. Complete QROS QED™ procedures are on file with the NCDEQ and are available upon request. The QROS QED™ analysis was conducted by RED Lab personnel at their
laboratory in Wilmington, North Carolina. QROS QED™ analysis provides
Benzene, Toluene, Ethylbenzene, and Total Xylenes (BTEX), DRO, GRO, TPH, total Aromatics (C10-C35) and 16 EPA PAH concentrations. A total of 10 soil samples were submitted to RED Lab. The COC documentation is included in Appendix C.

One (1) groundwater sample was submitted to ENCO in Cary, North Carolina for analysis per EPA Method 625 and Standard Method 6200B for the presence of semi-volatile and volatile organics. The COC documentation is included in Appendix C.

4.0 FIELD ACTIVITIES 4.1 CURRENT SITE CONDITIONS AND FIELD OBSERVATIONS

The site currently operates as a strip mall with retail stores. Businesses include: Mallard Grills and Fireplaces (which specializing in grills, fireplaces, and propane service), a nail salon and a tobacco shop. The property is identified as Mallard Grills & Fireplaces with a Facility ID 00-0-0000026001.
The building is outside of the proposed ROW and/or easement. Likewise,
the two (2) propane aboveground storage tanks (ASTs) located on the northeastern portion of the property are also outside of the proposed ROW and/or easement. No monitoring wells, septic tanks, or USTs were observed during site reconnaissance.

Photographs taken during the geophysical investigation are included in the geophysical survey provided in Appendix A. Figures 3 illustrates the subject site including soil borings and soil sample
locations. The groundwater sample location is shown on Figure 4.
4.2 SOIL SAMPLING
A total of 10 borings were advanced as part of this investigation and 10 soil
samples were collected (one from each boring) and submitted for analysis.
Boring/sample locations are illustrated on Figure 3. Boring logs are included in Appendix B. Soil sample borings were advanced between eight (8) and 12 feet below land
surface (BLS) and terminated in silty and clayey find sand in the deeper
boring 175DPT-01 and highly plastic clay with and without sand to moderately plastic clay in the remaining shallower borings. Soils were collected continuously to boring termination. After retrieving the drive, soil was visually/manually classified for USCS and screened for organic vapor
head space. Soil samples collected from each boring for analysis were
packed in the appropriate glassware, labeled, and placed in a cooler on ice. The 10 soil samples were submitted to RED Lab for QED™ analyses. The COC documentation is included in Appendix C.
4.3 GROUNDWATER SAMPLING One (1) groundwater sample (175DPT-01) was collected and submitted for analysis per EPA Method 625 and Standard Method 6200B under proper COC protocol (see Appendix C).
4.4 SURVEYING Boring/sample locations were recorded utilizing a Trimble® global positioning survey instrument and data collector. Boring coordinates are on the boring

5.0 RESULTS Historical review The Regional Aboveground Storage Tank (RAST) database lists AST Incident
#12229 (WA-12229) for Mallard Oil/James City Bulk Plant (Facility ID 00-0-
0000026001) at the parcel. According to the most recent Groundwater Monitoring Report for this incident, dated December 16, 2016, Mallard Oil Company (Mallard) operated a bulk fuel plant at the sire prior to construction of the current strip mall. Mallard removed seven (7) 20,000- gallon and three (3) 30,000-gallon ASTs from
the site in June 2000. Mallard had owned and operated the ASTs from 1984 until
the time the tanks were removed, along with the dispenser islands and associated piping. The release associated with Incident# 12229 was initially discovered in August 1993
when free-product was discovered in the drainage ditch that runs along the western
property line. The release was suspected to be from a product line running beneath Dispenser Island #1 and the quantity of the release was unknown. Mallard replaced the leaking product line and all other product lines for the dispenser islands.
Another release occurred in October 1994 when the product line under Dispenser
Island #1 was ruptured during construction of fencing at the site, releasing approximately 500 to 700 gallons of petroleum product. A Corrective Action Plan (CAP) was prepared in September 1994 recommending monitored natural attenuation for the dissolved phase contamination. A CAP Addendum was prepared
and approved by the North Carolina Department of Environment and Natural
Resources (NCDENR) adding limited free product and groundwater recovery using Soil Vapor Extraction (SVE) processes to the monitored natural attenuation. As of the November 17, 2016 monitoring event, seven (7) monitoring wells were sampled, with MW-4 exhibiting a sheen. Results indicated Benzene, Ethylbenzene, Methyl-
tert-Butyl Ether (MTBE), Naphthalene, n-propyl benzene, n-butylbenzene, Total
Xylenes, and 1,2,4,-Trimethbene concentrations exceeded the North Carolina Administrative Code (NCAC) T15A:2L Groundwater Quality Standard (2L GWQS) in monitoring wells MW-4 and MW-9, which are located on the southwest portion of the property. No further documentation was on file since the November 2016
monitoring report. File review information is provided in Appendix D.
A 1,000-gallon new/used oil UST was installed on January 1964. The tank was for commercial use and constructed of single walled steel. A subsequent tank closure report dated April 21, 1999 indicated the 1,000-gallon waste oil tank was removed
on February 23, 1999. No odors or staining were present during removal and the
tank appeared to be in good condition. Soil samples taken from beneath the tank basin were below regulatory levels, although the stockpile sample Stp-1 (taken from soils excavated from the tank pit) revealed EPA Method 3550 DRO at 18.9 parts per million (ppm), which at the time was above the regulatory limit. The closure report

recommended no further action and no incident was assigned in the Regional Underground Storage Tank (RUST) database for it. File review information is provided in Appendix D.
Geophysical Investigation The geophysical investigation consisted of electromagnetic (EM) induction-metal detection and ground penetrating radar (GPR) surveys. A total of seven (7) EM
anomalies were identified. The majority of the EM anomalies were directly attributed
to visible cultural features such as vehicles, a sign, reinforced pipes, and mailboxes. GPR did not record evidence of unknown significant structures or metallic USTs. The complete geophysical survey report by Pyramid is included in Appendix A.
Site Features The site currently operates as a strip mall with retail stores. According to the Craven County property card the parcel consists of 1.759 acres and contains a 16,500 square feet (ft2) building that was built in 2001. The building is outside of the ROW
and/or easement. The two (2) propane tanks are on the northeast portion of the
property and are outside of the proposed ROW and/or easement. Soil
Soil boring 175DPT-01 was terminated in silty and clayey fine sand at 12 feet BLS.
Borings 175DPT-02 and -03 were terminated in sandy highly plastic clay at eight (8’) BLS. Borings 175DPT-04 through -06 and 175DPT-08 through -10 were all terminated in a highly plastic clay at eight (8’) BLS. Soil boring 175DPT-07 was terminated in sandy moderately plastic clay at eight (8’) BLS. Complete boring logs
are provided in Appendix B. A soil sample was collected from each boring between
four (4) and five (5) feet BLS and submitted for laboratory analysis. The complete analytical report and chain of custody documents are provided in Appendix C. The soil headspace OVA results ranged from 1.2 ppm [at 175DPT-01 (0-2’)] to
1,280 ppm [at 175DPT-06 (2-4’)]. The soil headspace screening is summarized in
Table 1. All TPH GRO/DRO soil sample results were reported as less than method detection limits and/or State Action Levels except the 175DPT-05 (4’), 175DPT-06 (4’),
175DPT-08 (4’) , 175DPT-09 (5’) , and 175DPT-10 (5’) soil samples. The 175DPT-
05 (4’) soil sample reveled TPH DRO at 375 mg/kg. The 175DPT-06 (4’) soil sample revealed TPH GRO at 275.5 mg/kg and TPH DRO at 346 mg/kg. The 175DPT-08 (4’) soil sample revealed TPH DRO at 857 mg/kg. The 175DPT-09 (5’) soil sample revealed TPH GRO at 71 mg/kg. The 175DPT-10 (5’) soil sample
revealed TPH GRO and TPH DRO at 226.4 mg/kg and 182.4 mg/kg, respectively. Summarized TPH results are provided on Table 2 and illustrated on Figure 3. The stimated impacted soil areas are illustrated around the 175DPT-05, 175DPT-06 175DPT-08, 175DPT-09, and 175DPT-10 borings on Figure 3. The area around

175DPT-05 and 175DPT-06 is approximately 7,098 ft2. This area contains roughly 631 cubic yards of soil above the water table (2.4’ BLS). The area around 175DPT-08, 175DPT-09, and 175DPT-10 is approximately 6,013 ft2. This area contains
roughly 535 cubic yards of soil above the water table (2.4’ BLS).
Groundwater The EPA Method 625 analyte Naphthalene was detected at a concentration above
the NCAC 2L GWQS in groundwater sample 175DPT-01. Several Standard
Method 6200B analytes were revealed in the 175DPT-01 sample; Benzene, MTBE, and Naphthalene results were all above their corresponding NCAC 2L GWQS. The groundwater sample results are summarized on Table 3. The groundwater sample location and summarized results are illustrated on Figure 4. The complete
laboratory analytical report is provided in Appendix C.
Depth to groundwater was measured in the temporary monitoring well several hours after installation. The groundwater measurement in temporary monitoring well 175DPT-01 was 2.4 feet below the top of casing (near the ground surface). The
groundwater measurement is included on the boring log in Appendix B.
6.0 SUMMARY AND CONCLUSIONS
The Parcel 175 site owned by Mallard Oil Co. at 1230 E US 70 Hwy in New Bern,
North Carolina currently operates as a strip mall with retail stores including Mallard
Grills and Fireplaces, a nail salon and a tobacco shop. The building and two (2) ASTs are all outside of the proposed ROW and/or easement. No monitoring wells, USTs, or septic tanks were observed or revealed during site reconnaissance.
One soil sample was collected from each of 10 borings advanced during this
investigation and submitted for TPH DRO/GRO analysis. Laboratory analyses revealed TPH GRO concentrations above State Action Levels in three (3) of the 10 soil samples collected (175DPT-06, 175DPT-09, and 175DPT-10). TPH DRO concentrations above the State Action Levels were revealed in four (4) of the 10 soil
samples (175DPT-05, 175DPT-06, 175DPT-08, and 175DPT-10). A total of
approximately 1,166 cubic yards of TPH impacted soil above the water table (2.4’ BLS) were identified within the parcel. The soil samples may have been collected from the capillary fringe or below the
water table and analytical results may be indicative of groundwater contamination
and not vadose soil conditions. However, elevated headspace OVA results were recorded in the soil interval(s) above the soil samples submitted for laboratory analysis. Therefore, estimated impacted soil areas and total volume relies on the analytical results, OVA screening, and assumes vadose impacted soils from the
surface to 2.4 feet BLS. One (1) groundwater sample (175DPT-01) was collected near a proposed catch basin on the middle of the western portion of the property. Laboratory analysis indicated Benzene, MTBE, and Naphthalene results were all above their

corresponding NCAC 2L GWQS . Groundwater in the temporary monitoring wells was measured at approximately 2.4 feet BLS.
7.0 LIMITATIONS This report is based on the agreed work scope and a review of available data from limited sampling. It is possible that this investigation may have failed to reveal the presence of contamination in the project area where such contamination may exist.
Although CATLIN has used accepted methods appropriate for soil and groundwater
sampling, CATLIN cannot guarantee that additional soil and/or groundwater contamination does not exist. 8.0 SIGNATURES

EXECUTIVE SUMMARY

Project Description: Pyramid Environmental conducted a geophysical investigation for
Catlin Engineers & Scientists at Parcel 175, located at 1230 East U.S. 70, in New Bern,
NC. The survey was part of a North Carolina Department of Transportation (NCDOT)
Right-of-Way (ROW) investigation (NCDOT Project U-5713 & R-5777A&B). The survey
was designed to extend from the existing edge of pavement into the proposed ROW and/or
easements, whichever distance was greater. Conducted from May 1-5, 2020, the
geophysical investigation was performed to determine if unknown, metallic underground
storage tanks (USTs) were present beneath the survey area.

Geophysical Results: The geophysical investigation consisted of electromagnetic (EM)
induction-metal detection and ground penetrating radar (GPR) surveys. A total of seven
EM anomalies were identified. The majority of the EM anomalies were directly attributed
to visible cultural features. GPR did not record any evidence of unknown significant buried
structures such as USTs. Collectively, the geophysical data did not record any evidence of
metallic USTs at Parcel 175.

INTRODUCTION

Pyramid Environmental conducted a geophysical investigation for Catlin Engineers &
Scientists at Parcel 175, located at 1230 East U.S. 70, in New Bern, NC. The survey was
part of a North Carolina Department of Transportation (NCDOT) Right-of-Way (ROW)
investigation (NCDOT Project U-5713 & R-5777A&B). The survey was designed to
extend from the existing edge of pavement into the proposed ROW and/or easements,
whichever distance was greater. Conducted from May 1-5, 2020, the geophysical
investigation was performed to determine if unknown, metallic underground storage tanks
(USTs) were present beneath the survey area.

The site included a commercial strip mall building surrounded by asphalt and grass
medians. An aerial photograph showing the survey area boundaries and ground-level
photographs are shown in Figure 1.

FIELD METHODOLOGY

The geophysical investigation consisted of electromagnetic (EM) induction-metal
detection and ground penetrating radar (GPR) surveys. Pyramid collected the EM data
using a Geonics EM61-MK2 (EM61) metal detector integrated with a Geode External
GPS/GLONASS receiver. The integrated GPS system allows the location of the instrument
to be recorded in real-time during data collection, resulting in an EM data set that is geo-
referenced and can be overlain on aerial photographs and CADD drawings. A boundary
grid was established around the perimeter of the site with marks every 10 feet to maintain
orientation of the instrument throughout the survey and assure complete coverage of the
area.

According to the instrument specifications, the EM61 can detect a metal drum down to a
maximum depth of approximately 8 feet. Smaller objects (1-foot or less in size) can be
detected to a maximum depth of 4 to 5 feet. The EM61 data were digitally collected at
approximately 0.8-foot intervals along north-south trending or east-west trending,

Parcel 175 – 1230 East U.S. 70 (NCDOT Project U-5713 & R-5777A&B) 3 | Page
New Bern, North Carolina
generally parallel survey lines, spaced five feet apart. The data were downloaded to a
computer and reviewed in the field and office using the Geonics NAV61 and Surfer for
Windows Version 15.0 software programs.

GPR data were acquired across select EM anomalies on May 5, 2020, using a Geophysical
Survey Systems, Inc. (GSSI) SIR 4000 control unit coupled to a 350 MHz antenna. Data
were collected both in reconnaissance fashion as well as along formal transect lines across
EM features. The GPR data were viewed in real-time using a vertical scan of 512 samples,
at a rate of 48 scans per second. GPR data were viewed down to a maximum depth of
approximately 6 feet, based on dielectric constants calculated by the DF unit in the field
during the reconnaissance scans. GPR transects across specific anomalies were saved to
the hard drive of the DF unit for post-processing and figure generation.

Pyramid’s classifications of USTs for the purposes of this report are based directly on the
geophysical UST ratings provided by the NCDOT. These ratings are as follows:

DISCUSSION OF RESULTS

Discussion of EM Results
A contour plot of the EM61 results obtained across the survey area at the property is
presented in Figure 2. Each EM anomaly is numbered for reference in the figure. The
following table presents the list of EM anomalies and the cause of the metallic response, if
known:

Metallic Anomaly # Cause of Anomaly Investigated with GPR
1 Vehicles
2 Sign
3 Reinforced Pipes
4 Mailbox
5 Reinforced Pipes
6 Mailboxes
7 Vehicles 

The majority of the EM anomalies were directly attributed to visible cultural features at the
ground surface, including vehicles, a sign, reinforced pipes, and mailboxes. GPR was
performed across areas exhibiting metallic interference from vehicles to verify that the
interference did not obscure any buried structures such as USTs. GPR was also performed
across minor EM anomalies not included in the table above to verify their nature.

Discussion of GPR Results
Figure 3 presents the locations of the formal GPR transects performed at the property, as
well as select transect images. A total of eleven formal GPR transects were recorded. All
of the GPR transect images are included in Appendix A.

GPR Transects 1-7 and 10-11 were performed around vehicles. None of these GPR
transects recorded evidence of significant unknown buried structures such as USTs. GPR
Transects 8 and 9 were performed across minor, isolated EM features. GPR Transect 8
recorded an isolated hyperbolic reflector that was suggestive of a possible utility or buried
debris. Transect 9 did not record any significant features.

Collectively, the geophysical data did not record any evidence of unknown metallic USTs
at Parcel 175. Figure 4 provides an overlay of the metal detection results onto the NCDOT
MicroStation engineering plans for reference.

SUMMARY & CONCLUSIONS

Pyramid’s evaluation of the EM61 and GPR data collected at Parcel 175 in New Bern,
North Carolina, provides the following summary and conclusions:
• The EM61 and GPR surveys provided reliable results for the detection of metallic
USTs within the accessible portions of the geophysical survey area.
• The majority of the EM anomalies were directly attributed to visible cultural
features.
• GPR did not record any evidence of unknown significant buried structures such as
USTs.
• Collectively, the geophysical data did not record any evidence of metallic USTs at
Parcel 175.

LIMITATIONS

Geophysical surveys have been performed and this report was prepared for Catlin
Engineers & Scientists in accordance with generally accepted guidelines for EM61 and
GPR surveys. It is generally recognized that the results of the EM61 and GPR surveys are
non-unique and may not represent actual subsurface conditions. The EM61 and GPR
results obtained for this project have not conclusively determined the definitive presence
or absence of metallic USTs, but the evidence collected is sufficient to result in the
conclusions made in this report. Additionally, it should be understood that areas containing
extensive vegetation, reinforced concrete, or other restrictions to the accessibility of the
geophysical instruments could not be fully investigated.
