Thanks for the info Chad. We did give the USCG Loran Station a No Further Action (attached). They had some area's
around the buildings and towers that had some minor soil issues. It was my understanding that the property was being
decommissioned in order to sell. May be a good place for the soil unless a major residential development is planned for
the area.

Good afternoon,
I am working with the town of Carolina Beach and their stormwater lake dredging project. This project is being conducted
under an approved US Corps of Engineers permit. The town is unable to continue to store the dredged material on the
earlier approved location adjacent to their WWTP. As such, we are searching for an additional location. The town has an
isolated 5 acre parcel near the USCG LORAN property. This area is currently landlocked, undeveloped, and unimpacted
by wetlands. We would like to use this location to permanently store the material because it does have some Arsenic
concentrations of approximately 6 to 8 ppm. We understand the need for stormwater and erosion control. What other
requirements would the State have to approve this location for dredge spoil storage?
Thanks and have a good weekend.

I have reviewed the file information provided to the Inactive Hazardous Sites Branch (Branch)
including the Statement of Attainment of Cleanup Levels and No Further Action Request received
on January 29, 2016. On January 28, 2016, Arcadis G&M of North Carolina submitted the FINAL
Site Investigation Report for the above referenced site (the "Site").
Several compounds, including Benzo(a) Anthracene, Benzo(a) Pyrene, Benzo(b) Flurorathene,
arsenic, lead, and hexavalent chromium, were detected in the soils at concentrations above initial
screening levels. Further delineation and assessment indicates that none of these compounds are
above remedial action levels. Thallium and manganese were detected in the groundwater above
the NCAC 2L Groundwater Standards or Interim Maximum Allowable Concentrations during
initial sampling. Subsequent sampling indicates that the initial results were not repeatable.
Based on this data, this Site has been transferred to the "No Further Action" category in the Inactive
Hazardous Sites Branch's inventory of sites. No further remedial action will be required unless
the Department later determines, based on new information or information not previously provided
to the Department, that hazardous substances are present at values exceeding current standards or
that the Department was provided with false or incomplete information. If there are any questions,
please call me at [phone].

• Hazardous materials storage buildings; and
• An on -site drum storage area.
Based on the information contained in the attached SIR, limited environmental
impacts exist at the Site. Also based on our prior conversations with you, the low
constituent concentrations that are present at the site (i.e., polycyclic aromatic
hydrocarbons, arsenic, lead, and manganese) are not of environmental concern
because they are not present above adjusted soil screening levels. Therefore,
Arcadis respectfully submits the attached SIR and Statement of Attainment of
Cleanup Levels for your reconsideration of issuing a No -Further Action (NFA)

Site Name: USCG LORSTA Carolina Beach
City: Wilmington
Street Address: 9001 River Road
County: New Hanover
Site Inactive Hazardous Sites ID#: NONCD0001475
For purposes of this certification, the "site" is defined as the above -identified property and any
additional area which has become contaminated as a result of hazardous substances or other non -
petroleum, non -biological contaminants released at the property.
For purposes of this certification, "known and suspected areas of concern" only include those areas
where some evidence of a disposal or spill has occurred such as soil staining, or other visual evidence
of spillage, reported spills, known tank leaks, and other similar such data.
For purposes of this certification, "known and suspected contaminants" shall include all contaminants
known to have been spilled, disposed, or otherwise discharged in a known or suspected area of
concern and any degradation products of those contaminants. Where information is limited on the
specific compounds discharged, laboratory analytical methods must at a minimum Include GUMS
analysis for volatile and semi -volatile organic compounds, and analysis for hazardous substance list
metals.
I, Donald Malone (environmental consultant), state and affirm:
have reviewed all the available environmental records for the above -identified site and render this
statement based on that review. This certification is based on a records review and is not a certification
of the accuracy of the facts asserted in documents prepared by others. I have found the sampling and
analytical methods to be consistent with the nature and type of contamination known or suspected to
be present at the site. All suspect areas and known and suspected contaminants have been
adequately investigated based on available documentation. This certification does not rely on any
information I have found to be in error.
All contaminated groundwater, soil, surface water, and sediment at the site has been treated or
removed so that no known hazardous substances or non -petroleum, non -biological contamination
remains in excess of the current Inactive Hazardous Sites Branch (1) protection of groundwater criteria
for soils, (2) direct contact remediation goals for soils for unrestricted use, and (3) remediation goals for
groundwater, surface water and sediment (reference Inactive Hazardous Sites Program Guidelines for
Assessment and Cleanug for remediation goals).

1. Introduction
This Site Investigation Report (SIR) was prepared by Arcadis G&M of North Carolina,
Inc. (Arcadis) on behalf of the United States Coast Guard (USCG) for the Long Range
Navigation (LORAN) Station (LORSTA) located in Carolina Beach, North Carolina
(Site; see Figures 1 and 2). This SIR summarizes Initial Site Evaluation (ISE) activities
completed at the Site to be consistent with the National Oil and Hazardous Substances
Pollution Contingency Plan, 40 Code of Federal Regulation Part 300. These activities
were outlined in the Field Sampling Plan (FSP; Arcadis, 2013b), Quality Assurance
Project Plan (QAPP) (Arcadis, 2013c) and the QAPP Addendum (Arcadis, 2014)
previously prepared for the Site.
1.1 Setting and Site Description
The USCG LORSTA Carolina Beach Site consists of approximately 210 acres and is
located at 9001 River Road, Carolina Beach, New Hanover County, North Carolina
(see Figure 1).
The Site is bordered by residential properties to the north, residential properties and
wooded, undeveloped areas to the east and south, and by River Road to the west.
U.S. Coast Guard Road enters the Site from River Road to the southwest. The
operational portion of the Site is fenced, but the fence does not follow the property
boundary on all sides. The property boundary was surveyed in 2013 and can be seen
on Figure 2. The Site consists of the following current structures: Administration
Building, Operations Building, Multi -Purpose Building, Barracks, and Storage Building.
There are also two decommissioned 2,000-gallon diesel fuel above -ground storage
tanks (ASTs), two decommissioned 50-gallon diesel fuel day tanks, one
active1,000-gallon heating oil AST, and one inactive 550-gallon heating oil AST. There
are approximately eight USCG personnel stationed in the Multi -Purpose Building. The
remaining site structures are currently vacant. Former site structures include four
625-foot LORAN Towers (north, south, east, and west) removed in 2014, the Former
Hazardous Material Storage Building (see Figure 2), and a Former Central Tower
damaged by a hurricane in 1958 (not shown on figures).
The topography of the Site is generally flat with some low areas to the north. Site
structures are situated on the central portion of the Site, which is cleared of trees and
periodically mowed -(see Figure 2). The remaining areas of the Site are wooded and
undeveloped.

1.2 Identification of Potential Source Areas
Based on previous assessments discussed in section 1.2.3 of the Field Sampling Plan
submitted to the United States Environmental Protection Agency (USEPA) on
February 15, 2013, historical site documentation, and the initial site visit completed by
Arcadis in September 2011, several areas of the Site were identified as areas of
potential interest. These areas of potential interest included:
• The potential for impacted soil and groundwater associated with chipping/flaking of
weathered lead -based paint from existing buildings/structures, towers, and former
site structures;
• The potential for soil and groundwater impacts related to the heating oil and diesel
fuel ASTs and associated piping and diesel fuel day tanks;
• The potential for soil impacts associated with transformers and/or electronic
communications equipment used in LORAN Operations;
• The potential for soil and groundwater impacts related to the Storage Building and
the Former Hazardous Materials Storage Building; and
• The potential for soil and groundwater impacts related to on -Site drum storage.
Additional detail regarding the identification of potential source areas at the Site is
included in the FSP (Arcadis, 2013b).
2. Site Investigation Activities
An ISE was conducted to identify potential risks to human health and the environment.
A portion of the ISE was completed March 4 through 13, 2013, including biased soil
sampling near current and former site structures (with the exception of the four LORAN
Tower [North, South, East, and West] locations) and monitoring well installation. A site -
specific Health and Safety Plan (Arcadis, 2013a) was developed prior to mobilization to
the Site that established health and safety procedures to minimize potential risks to
Arcadis and subcontractors implementing the ISE.
A property boundary survey was performed by The Clark Group during ISE activities in
March 2013 to correctly identify the property boundary, as the fence line does not
follow the property boundary in all areas of the Site. A copy of the boundary survey is
provided in Appendix A.

During ISE activities in March 2013, GARCO Inc. (GARCO) provided waste disposal
services and removed miscellaneous debris including wood pallets and trash from the
northeastern edge of the Site. Waste was transported to the GARCO facility in
Asheboro, North Carolina for disposal. The Bill of Lading from this disposal is included
in Appendix B.
Prior to advancement of the direct push soil borings and monitoring wells, a private
utility locating firm, Sweetwater Utility Exploration, LLC (Sweetwater), cleared boring
locations of underground utilities/obstructions. Numerous utilities were identified
surrounding the Administration and Operations Buildings, including active and
potentially abandoned electric lines. Due to the potential hazards posed by these
utilities, Sweetwater cleared all boring locations in the vicinity of these buildings with an
air knife to a minimum depth of 5 feet below ground surface (bgs). Several soil boring
and monitoring well locations proposed in the FSP were relocated in the field to avoid
underground utilities.
The USCG dismantled and removed the North, South, East, and West LORAN towers
from the Site in April and May 2014. A photo log depicting this process is included in
Appendix C.
Additional ISE activities were completed following demolition of the towers between
June 16 and 25, 2014, including biased soil sampling near the former towers, unbiased
soil sampling, additional monitoring well installation, and groundwater sampling as
described in the FSP (Arcadis, 2013b).
2.1 Soil Sampling Methodology
2.1.1 Paint Impacts
A biased sampling approach was used to target areas of potential impact during field
activities. Surface and shallow subsurface soil surrounding existing buildings and
former Site structures were evaluated for potential impacts related to the weathering of
lead -based exterior building paint that had been applied to these structures. Existing
buildings include the Operations Building, Administration Building, Multi -Purpose
Building, Barracks, and Storage Building. Former site structures include three concrete
pads from former antennas, the former Central Tower, four Former LORAN Towers
(North, South, East, and West), and the Former Hazardous Material Storage Building.
Soil samples were first collected from surface soils (0 to 6 inches bgs) adjacent to
current site structures. Surface soil samples were collected approximately 1 to 2 feet
from the exterior building walls, at an average spacing of approximately 1 sample per

25 linear feet with at least one sample collected from each side of a building. For
former structures, the initial biased samples were placed as close to the former
structure as possible, based on maps if no evidence of the location of the former
structure or evidence of paint chips was observed.
Flaking and peeling paint was noted on concrete pads for former antennas during the
initial Site visit. Because of this, two samples were collected adjacent to each of these
pads.
LORSTA Carolina Beach originally had one central tower, which was damaged by
Hurricane Helene in 1958. The top of the tower broke off and fell parallel to the Multi -
Purpose Building and Barracks. Because of this, two samples were collected adjacent
to the asphalt in this area, in addition to the samples already planned adjacent to the
buildings.
The USCG dismantled and removed the North, South, East, and West LORAN towers
from the Site in April and May 2014. The towers were dismantled in a way to reduce
the potential of contributing additional flaking lead -based paint to the Site soils. As
such, materials were stored on plastic sheeting before being transported from the Site.
One instance of materials being staged on the ground surface was noted in photos
provided to Arcadis, included in Appendix C. An additional sample was collected from
this location (northeast of the South LORAN Tower) due to this staging practice.
A field screening level for lead of 100 milligrams per kilogram (mg/kg) was used to
compare to results from an x-ray fluorescence (XRF) analyzer, as identified in the
FSP (Arcadis, 2013b). When impacts were identified in surface soils (i.e., XRF
measurements greater than 100 mg/kg lead) during field screening, samples were
collected from subsequent depths at the same location and screened using the XRF
for vertical delineation. Furthermore, if impacts were identified in the surface soil, a
step -out location was completed and analyzed with the XRF for lateral delineation. It
should be noted that the field screening level of 100 mg/kg was chosen to be
conservative, and is less than the following applicable North Carolina Department of
Environmental Quality (NCDEQ) formerly the North Carolina Department of
Environment and Natural Resources (NCDENR) (NCDEQ, 2015a) Preliminary Soil
Remediation Goal (PSRG) for lead and other lead -containing compounds:
• Industrial Health -Based PSRG of 800 mg/kg,
• Residential Health -Based PSRG of 400 mg/kg, and
• Protection of Groundwater PSRG.of 270 mg/kg.

Soil samples collected were submitted for laboratory analysis of lead by USEPA
Method 6020A. Additionally, the sample location with the highest lead concentration
(as measured by the XRF) at each building or structure was also submitted for
analysis of volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs),
and hexavalent chromium. (Arcadis, 2013b, 2013c).
Soil boring locations are shown on Figures 3 through 5. Details regarding laboratory
analytical results are included in Section 3.2.1. Soil boring logs are included in
Appendix D.
2.1.2 AST and LORAN Operations Impacts
Several areas on -site were investigated to assess the potential for soil impacts related
to Site ASTs and associated piping, day tanks, and LORAN operations during the ISE
(Figure 6).
Soil lithology was continuously logged on borehole log sheets by the Arcadis field
geologist and soil samples were evaluated in the field for visible impacts and screened
using a flame ionization detector (FID) in accordance with the Standard Operating
Procedure (SOP) included in the FSP (Arcadis, 2013b). Arcadis collected two soil
samples from each soil boring and monitoring well location. The water table was
encountered at approximately 12 to 13.5 feet bgs. A soil sample was collected from
the surface or from the area of highest FID reading and the second sample was
collected just above the capillary fringe. No visual impacts or odors were noted.
Soil Borings SB-00 through SB-RR and SB-TT through SB-VV and five Monitoring
Wells (MW-1 through MW-4 and MW-7) were advanced to depths ranging between 10
to 20 feet bgs to investigate potential impacts in the vicinities of the ASTs and day
tanks. Soil samples collected in the vicinities of the heating oil ASTs, diesel fuel
ASTs, and diesel fuel day tanks were submitted for laboratory analysis of Target
Compound List (TCL) VOCs in accordance with USEPA Method 8260E and
polynuclear aromatic hydrocarbons (PAHs) in accordance with USEPA Method
8270C.
Based on the potential for PCBs to have been used in transformers and LORAN
equipment, soil adjacent to site transformers and the Operations Building was
investigated for potential impacts. Six soil borings (SB-II through SB-NN; Figure 6)
were each advanced to a depth of 15 feet bgs. Soil samples collected in the vicinity of
the Operations Building and site transformers were submitted for laboratory analysis
of PCBs in accordance with USEPA Method 8081.

2.1.3 Storage Building Impacts
The existing Storage Building and Former Hazardous Material Storage Building were
investigated to evaluate potential impacts associated with these structures (Figures 5
and 6). Two soil borings (SB-WW and SB-XX) were each advanced to a depth of
10 feet bgs. Two soil samples were collected from each soil boring using a hand auger
for shallow subsurface sampling (up to 5 feet bgs) and using direct push technology
(DPT) drilling techniques for advancing boreholes beyond 5 feet bgs. The water table
was encountered at approximately 7 to 8 feet bgs.
Soil lithology was continuously logged on borehole log sheets by the Arcadis field
geologist and soil samples were evaluated in the field for visible impacts and screened
using an FID in accordance with the SOP included in the FSP (Arcadis, 2013b). A soil
sample was collected from the area of highest FID reading and the second sample was
collected just above the capillary fringe in each boring. No visual impacts or odors were
noted in the soil borings. Soil samples were submitted for laboratory analysis of TCL
VOCs in accordance with USEPA Method 8260, TCL SVOCs in accordance with
USEPA Method 8270, and NCDEQ IHSB 14 Metals in accordance with USEPA

During ISE activities, GARCO provided waste disposal services and removed the
55-gallon drums and their contents. Due to the poor condition of the drums, GARCO
transferred the liquid contents of the drums into totes prior to disposal. The waste was
transported to the GARCO facility in Asheboro, North Carolina for disposal. Arcadis
collected five composite samples from the drums, submitting the samples for laboratory
analysis of:
• Toxicity characteristic leaching procedure (TCLP) VOCs in accordance with
USEPA Method 826013;
• TCLP SVOCs in accordance with USEPA Method 8270C;
• TCLP NCDEQ IHSB 14 Metals in accordance with USEPA Methods 6020A and
7470A;
• PCBs in accordance with USEPA Methods 8081 B;
• pH in accordance with USEPA Method 9040C; and
• Flammability and paint filter in accordance with USEPA Method 1010A.
Eighteen soil borings were advanced (SB-AB through SB-AS) and two Monitoring
Wells (MW-5 and MW-6) installed to depths ranging from 4 to 20 feet bgs. Soil borings
located in the clearing (SB-AB through SB-AM) were advanced using a hand auger, as
the water table was encountered at approximately 3 to 4 feet bgs. Soil borings located
in the woods and the monitoring wells (SB-AN through SB-AS, MW-5, and MW-6) were
sampled with a hand auger for surface and shallow subsurface sampling (up to 5 feet
bgs) and DPT for advancing boreholes beyond 5 feet bgs. The water table was
encountered at approximately 11 to 12 feet bgs in the woods and 4 feet bgs in the
clearing.
Soil lithology was continuously logged on borehole log sheets by the Arcadis field
geologist and soil samples were evaluated for visible impacts, or staining, and
screened using a FID in accordance with the SOP included in the FSP (Arcadis,
2013b). Arcadis collected two soil samples from each soil boring. A soil sample was
collected from either the surface soil or collected from the area of highest FID reading
and/or observed impacts (e.g. staining or odor). In cases of the absence of visual
impacts to soil or FID readings, the first soil sample was collected between ground
surface and 2 feet bgs and the second sample was collected just above the capillary
fringe. All soil samples were submitted for laboratory analysis of TCL VOCs in

regarding laboratory analytical results are included in Section 3.2.4. Waste manifests
are located in Appendix B. Soil boring and monitoring well construction logs are
included in Appendix D.
2.1.5 Unbiased Soil Sampling
Systematic random grid sampling was performed to evaluate soils where no current
site structures were present, no former structures were known to have been present,
and where no visual evidence of potential impacts was observed. This evaluation was
performed to identify potential impacts from previous structures that are no longer
present, or from other potential sources (e.g., relocated soil). This unbiased sampling
method is outlined in the FSP (Arcadis, 2013b).
Unbiased random grid samples were collected from the same depth intervals targeted
during the biased sampling. Field screening for lead was completed utilizing the same
methods as the biased lead sample locations, as discussed in Section 2.1.1. Unbiased
soil samples were collected and submitted for laboratory analysis of lead in accordance
with USEPA Method 6020A (Arcadis, 2013b, 2013c). Details regarding unbiased
sample analytical results are included in Section 3.2.5.
2.1.6 Background Samples
Two soil borings were advanced and completed as background monitoring wells
(MW-8 and MW-9) to characterize the soil types present at the Site (Figure 2). Soil
samples were evaluated for visible impacts, or staining, and screened using an FID.
Arcadis collected two soil samples from each soil boring location. A soil sample was
collected from the surface or from the area of highest FID reading and the second
sample was collected just above the capillary fringe. All soil samples were submitted
for laboratory analysis of NCDEQ 14 Metals by USEPA Method 6020AI7471A
(Arcadis, 2013b, 2013c).

2.2 Groundwater Sampling Methodology
Groundwater monitoring wells were installed to collect groundwater samples to
determine if soil impacts potentially present could have impacted groundwater.
Each monitoring well was installed using hollow stem auger drilling techniques to
create a minimum 4-inch diameter borehole to install the monitoring wells. In most
cases 10 gallons of potable water were used to drill the monitoring wells to counteract
the heaving sands encountered during the drilling events. Monitoring wells were
constructed of 2-inch diameter, Schedule 40 polyvinyl chloride (PVC) casings and 10-
foot long, 0.01-inch slot PVC screens. The annulus surrounding the screen was
backfilled using an appropriately sized sand pack for the slot size and surrounding
hydrogeologic unit to 2 feet above the top of the well screen. The remainder of the
borehole annulus was backfilled with 2 feet of bentonite chips and grout from land
surface to the top of the bentonite seal. The minimum grout thickness was 3 feet to
meet NCDEQ well installation standards for non -water supply wells. Monitoring wells
were completed with a sealable locking cap and a steel stick-up type cover set into a
concrete pad. Monitoring well construction logs can be found in Appendix D.
The monitoring wells were developed using a decontaminated submersible pump to
remove fines and establish hydraulic communication with the surrounding
hydrogeologic unit. The pump intake was moved up and down throughout the
screened interval to develop the entire screen interval. A field turbidity meter was used
to determine turbidity during development. Wells were developed until a turbidity of 10
nephelometric turbidity units (NTU) was achieved, with a minimum of three times the
volume of water used to drill the well purged from each well. Visual observations of the
purge water, along with field turbidity measurements and the volume of water purged
from each well, were recorded on well development logs.
Following well development, groundwater samples were collected for laboratory
analysis using a peristaltic pump under low -flow purging and sampling conditions.
Groundwater samples were collected as discrete or "grab" samples in June 2014 and
September 2014. Dedicated polyethylene tubing was used for each well. Arcadis
purged the wells by lowering the tubing to the midpoint of the well screen or
approximately 1 foot from the bottom of the well if the water level was lower than the
screen midpoint. A handheld multiparameter instrument (YSI) was used with a flow -
through cell to measure and record water quality field parameters including pH,
temperature, specific conductance, dissolved oxygen, and oxygen reduction potential.
A separate instrument was used to measure turbidity. Groundwater samples were
collected in the appropriate laboratory -supplied pre -preserved containers once field

parameters had stabilized (typically 2 to 3 consecutive readings within 10%) and 2 to 3
consecutive turbidity measurements less than 10 NTU. Samples were collected and
submitted for laboratory analysis of VOCs using USEPA Method 8260B, SVOCs using
USEPA Method 8270C, and total and dissolved NCDEQ IHSB 14 metals using USEPA
Methods 6020A and 7470A. (Arcadis, 2013b, 2013c)
Samples collected for dissolved metals analysis were field -filtered using an
appropriately sized filter (i.e., 0.45 micron) to allow naturally suspended colloidal
particles to pass, and preserved immediately following filtration. The water quality field
parameters were recorded on groundwater sampling logs. Groundwater samples were
placed in the appropriate laboratory -supplied containers, preserved, labeled, and
stored on ice to await shipment to the laboratory.
Monitoring well locations are shown on Figure 2. Monitoring well construction logs are
included in Appendix D. Details regarding groundwater sample analytical results are
included in Section 3.3.
2.3 Quality Assurance/Quality Control
2.3.1 Sample QA/QC
The quality assurance/quality control (QA/QC) samples associated with soil and
groundwater sampling included field equipment blanks, trip blanks, and field duplicates.
All QA/QC samples were prepared and collected according to the protocols specified in
the QAPP (Arcadis, 2013c). QA/QC sample frequency was completed as defined in the
QAPP.
2.3.2 Chain of Custody
Chain of custody (COC) forms, identifying each sample contained in a shipping
container, were completed and signed by the Arcadis field sampling personnel, sealed
in a plastic bag, and taped to the inside of the cooler, with custody seals in place on the
outside of the cooler. Samples were shipped from the Site to TestAmerica using an
overnight courier service. The TestAmerica location in Savannah, Georgia was used
for analytical services in 2013. Analytical services in 2014 were provided by
TestAmerica's North Canton, Ohio location. All samples were handled and shipped in
accordance with current Department of Transportation and International Air Transport
Association guidelines.
During the course of fieldwork, several revisions were made to the COC forms after
they were sent to TestAmerica due to sample identification errors, data validation level

changes (Level 3 vs. Level 2), and broken sample containers. Copies of all COC forms
with revisions can be found in Appendix E.
2.3.3 Field Documentation
Site activities were documented in a bound field notebook and daily logs. Included in
the daily documentation were:
• Procedures for sampling and other routine activities associated with the Site
activities;
• Logging of soil borings, field screening results, and analytical soil samples
collected;
• Construction of the permanent well installations;
• Personnel working on the Site; and
• Chronological log of Site activities.
Copies of the field notes from the ISE and subsequent groundwater sampling events
are provided in Appendix F.
2.4 Decontamination Procedures
Upon completion of sample collection, the sampling equipment was decontaminated
according to the procedures described in the FSP (Arcadis, 2013b). All equipment
used was cleaned prior to first use and between sample collection points. Cleaning of
equipment was performed to prevent cross -contamination between samples and to
maintain a clean working environment for all personnel.
All soil waste, personal protection equipment, and liquid waste including purge and
decontamination water, was stored on -Site in sealed 55-gallon drums and analyzed
prior to disposal. Soil waste samples were analyzed for the following:
• Total and TCLP lead in accordance with USEPA Methods 6010C or 6020A, and
1311/6010C or 1311/6020A, respectively;
Total and TCLP benzene in accordance with USEPA Method 8260B and
1311/826013, respectively; and

• Ignitability, pH, and paint filter test in accordance with USEPA Methods 1030,
9040C, and 90956, respectively.
Liquid waste samples were analyzed for the following:
• Total and TCLP lead in accordance with USEPA Methods 6010C or 6020A, and
1311/6010C or 1311/6020A, respectively;; and
• Total benzene in accordance with USEPA Method 8260B.
Investigation derived waste generated during the ISE was removed from the Site by
GARCO in June 2013 and July 2014. Liquid waste generated during the September
2014 groundwater sampling event is still stored on -Site and pending removal. All waste
was taken to the GARCO facility in Asheboro, North Carolina for disposal. Copies of
the waste manifests are included in Appendix B.
3. Site Investigation Results
3.1 Local Geology and Hydrogeology
The geology is generally consistent across the Site. The Site is primarily composed of
well sorted, very fine to fine sand from the surface to a depth of 20 feet bgs (deepest
explored). The topography of the Site is generally flat with some low areas to the north.
Depth to groundwater is also generally consistent across the Site. Groundwater was
encountered on the central, southern and northern wooded portions of the Site
between 11 and 13 feet bgs. The only variation in depth to water was encountered in
the clearing at the northern portion of the Site, where groundwater was encountered at
3 to 4 feet bgs (due to the lower surface elevation).
3.2 Data Validation
The laboratory analytical reports were reviewed and validated in accordance with the
QAPP (ARACDIS, 2013c), the most recent versions of the USEPA's National
Functional Guidelines (2004) and USEPA Region II Standard Operating Procedures
associated with SW-846 analysis for data validation, laboratory control limits, and
professional judgment. The laboratory's overall system performance and data quality
were acceptable and within the guidelines specified in the analytical method.
Data qualifiers were added to select data during the data validation process. Data
rejected during the data validation process did not impact the conclusions of this report.

Additional information regarding data qualifiers can be found in the laboratory data
validation reports, included in Appendix H. The data set collected during the ISE meets
the Data Quality Objectives as outlined in the QAPP (Arcadis, 2013b).
3.3 Soil Sample Results
3.3.1 Background Samples
Four background soil samples were collected, two each from Monitoring Well locations
MW-8 (0-0.5 and 7-8 feet bgs) and MW-9 (0-0.5 and 8-8.5 feet bgs) to determine
naturally occurring concentrations of NCDEQ IHSB 14 metals. These remote sampling
locations were chosen based on their distance from any current or historical structures
or known activities performed at the Site. The FID was used to screen these soils as
well for background petroleum hydrocarbons. Background FID readings were all 0.0
ppm.
Metals were not detected at concentrations exceeding the most restrictive PSRGs in
any of the background samples. The concentration ranges were:
• Arsenic: 0.17J to 0.32J mg/kg;
• Lead: 1.3 to 2.1 mg/kg; and
• Manganese: 1.6 to 2.7 mg/kg.
Background soil sample locations are shown on Figure 3. Laboratory analytical results
are summarized in Table 2. Laboratory analytical reports are attached in Appendix G.
The following provides a secondary line of evidence for background metal
concentrations in soil that commonly occur in North Carolina and/or the Eastern United
States (Dragun and Chekiri 2005):
• Arsenic: 1 to 18 mg/kg;
• Lead: non -detect to 50 mg/kg; and
• Manganese: non -detect to 7,000 mg/kg.

3.3.2 Metals Impacts
Field screening using the XRF during the ISE indicated concentrations of lead in soil
greater than the XRF screening level of 100 parts per million (ppm) in 4 of the 153 soil
samples collected (Table 1 and Figure 3). Samples SB-M (0-0.5 feet bgs), SB-N (0-0.5
feet bgs), SB-O (0-0.5 feet bgs), and SB-O (1-2 feet bgs) were located on the north
side of Building OM2 (Figure 3), and were the only samples that exceeded the XRF
screening level of 100 ppm. One soil sample, SB-M (0-0.5 fee bgs) also exceeded the
Protection of Groundwater PSRG but did not exceed the Industrial PSRG of 800
mg/kg. Additionally, the lead detections in the lower level samples at SB-M (1-2 feet
bgs) and SB-N (1-2 feet bgs) which were significantly lower, and did not exceed the
XRF screening level or Industrial PSRGs. Therefore, lead concentrations in soil should
not be of concern in 152 of the 153 soil samples collected at the facility.
Surface soil and vertical delineation soil samples were submitted for laboratory
analysis of lead and/or NCDEQ IHSB 14 metals. Metals analytical results were
compared to the PSRGs (NCDEQ 2015a) (Table 2; Figures 3 through 5).
All analytical results for lead were less than the most restrictive Protection of
Groundwater PSRG of 270 mg/kg, with one exception. Surface soil sample SB-M
(0-0.5 feet bgs), located on the northeast side of the Multi -Purpose Building,
contained a lead concentration of 340 mg/kg. This exceedance is delineated by soil
samples with lead concentrations less than the Protection of Groundwater PSRG
horizontally at locations SB-AT, SB-21, and SB-22, and vertically at SB-M (1-2 feet
bgs). Additionally, this concentration is less than the Residential Health -Based PSRG
of 400 mg/kg, and the Industrial Health -Based PSRG of 800 mg/kg.
Additionally, the sample location with the highest lead concentration (as measured
using the XRF) at each building or structure was also submitted for analysis of VOCs
(Table 3), PCBs (Table 4), and hexavalent chromium (Table 2, Figure 4). These
samples were collected from soil borings SB-H, SB-J, SB-M, SB-T, SB-DD, SB-HH,
SB-01, SB-08, SB-80, and SB-100.
Sample analytical results for arsenic were less than the most restrictive Residential
PSRG of 0.67 mg/kg with the following exceptions:
• Several sample locations located between the Multi -Purpose Building and
Administrative Building had concentrations of arsenic exceeding the most
restrictive Residential PSRG. The sample collected from the 0 to 0.5 foot interval at
location MW-3 had a concentration of 6.1 mg/kg, which is slightly greater than the
Protection of Groundwater PSRG of 5.8 mg/kg. This concentration is delineated

vertically by the 11 to 12 foot sample at location MW-3. Soil borings SB-15, SB-16,
SB-30, and SB-31 were each advanced to attempt to horizontally delineate the
arsenic exceedance in soil at MW-3. The concentrations of arsenic at these
locations ranged from 0.69J mg/kg to 0.85J mg/kg, each exceeding the most
restrictive PSRG. These data indicate that arsenic exceeding the Protection of
Groundwater PSRG is limited in extent and not likely migrating to groundwater at
concentrations above the Groundwater Standards. The exceedances in this area
are partially delineated horizontally by the samples from SBA and SBA4. Also,
all sample results are less than the highest concentration in the typical background
range for arsenic in North Carolina soils of 1 to 18 mg/kg (Dragun and Chekiri
2005).
• The sample collected from the 1 to 2-foot interval at location MW-7, located west of
the Multi -Purpose Building, had an arsenic concentration of 1.1 mg/kg. This
concentration is vertically delineated by the 10 to 11 foot sample from MW-7, and
horizontally by samples from SB-17, SB-18, SB-19 and SB-20. It is also less than
the highest typical background range for arsenic in North Carolina soils of 18
mg/kg (Dragun and Chekiri 2005).
Sample analytical results for manganese were less than the most restrictive PSRG for
the Protection of Groundwater of 65 mg/kg with the following exceptions:
The sample collected from the 0 to 0.5 foot interval at location MW-3, located
between the Multi -Purpose Building and Administrative Building, had a manganese
concentration of 280 mg/kg. This concentration is less than the Residential PSRG
of 360 mg/kg, and therefore does not pose a direct contact risk. This concentration
is delineated vertically by the 11 to 12 foot interval sample from MW-3, and
horizontally by the samples from SB-13, SB-14, SB-15, and SB-16.
• The sample collected from the 2 to 2.5 foot interval at location MW-5, located in the
former drum storage area in the clearing, had a manganese concentration of 76
mg/kg. This concentration is less than the Residential PSRG of 360 mg/kg, and
therefore does not pose a direct contact risk, This concentration is delineated
vertically by the sample from location SB-AB, and horizontally by the samples from
SB-AC, SB-AD, SB-AF, and SB-27.
All sample results are less than the highest concentration in the typical background
range for manganese in North Carolina soils of 7,000 mg/kg (Dragun and Chekiri
2005).

Hexavalent chromium was also analyzed in samples collected from locations SB-32
through SB-40 in June 2014 to confirm findings during the March 2013 portion of the
ISE. Hexavalent chromium was not detected at these locations, with the following
exceptions:
The sample from SB-H (0-0.5 feet bgs) exceeded the Residential PSRG of 0.30
mg/kg with a concentration of 0.49J mg/kg in March 2013. This concentration is
less than both the Industrial PSRG and the Protection of Groundwater PSRG. This
concentration is delineated by the samples collected from SB-32, SB-33, 813-34,
and SB-35 in June 2014.
The sample from SB-80 (0-0.5 feet bgs) in June 2014 had a hexavalent chromium
concentration of 0.66J mg/kg. This concentration is less than both the Industrial
PSRG and the Protection of Groundwater PSRG. Therefore, although no nearby
sample locations were analyzed for hexavalent chromium, it is unlikely that
hexavalent chromium is widespread in concentrations that would pose a risk to
human health.
Neither PCBs nor VOCs were detected in these samples at concentrations
exceeding the most restrictive PSRGs.
Soil sample locations are shown on Figures 3 through 5. XRF and laboratory analytical
results are: summarized in Tables 1 and 2, respectively. Laboratory analytical reports
are attached in Appendix G.
3.3.3 AST and LORAN Operations Impacts
Soil samples collected for evaluation of potential impacts related to the heating oil and
diesel fuel ASTs and associated piping, diesel fuel day tanks and LORAN operations
are shown on Figure 6. Soil samples from SB-00 through SB-RR, SB-TT through SB-
W, and monitoring wells MW-1, MW-2, MW-3, MW-4, and MW-7 were used to
evaluate these locations (Tables 3, 4 and 5),
VOCs were not detected at concentrations exceeding the most restrictive PSRGs in
these samples. SVOCs were not detected at concentrations exceeding the most
restrictive PSRGs with the following exceptions:
• Sample location MW-3, located between the Multi -Purpose Building and
Administrative Building, had concentrations of benzo(a)pyrene exceeding the most
restrictive PSRGs with a concentration of 83J micrograms per kilogram (pg/kg) a.
These concentrations are delineated vertically by the sample from MW-3 from 11

to 12 feet bgs. Soil borings SB-13 through SB-16 were advanced to attempt to
horizontally delineate the SVOC exceedances at MW-3. Concentrations of
benzo(a)pyrene, benzo(b)flouranthene, benzo(a)anthracene,
dibenzo(a,h)anthracene, and/or indeno(1,2,3-cd)pyrene exceeded the most
restrictive PSRGs at these locations, although not all the concentrations were
greater than all of the PSRGs and all (but SB-16 for benzo(a)pyrene) were less
than the industrial PSRG.
Sample location SB-RR, located west of the Multi -Purpose Building, had a
concentration of benzo(a)pyrene exceeding the most restrictive PSRG with a
concentration of 25 pg/kg (42 pg/kg in the SB-RR duplicate sample). This
concentration is delineated vertically by the sample from SB-RR from 10-10.5 feet
bgs. Soil borings SB-23 through SB-26 were advanced to attempt to horizontally
delineate the SVOC exceedances at SB-RR. No SVOCs were detected at
concentrations exceeding the most restrictive PSRGs at SB-23 or SB-24, located
south of SB-RR. Location SB-25, also located south of SB-RR, and location SB-
26, located east of SB-RR, both had SVOC exceedances of the most restrictive
PSRGs. A former underground storage tank was previously removed from the
adjacent parking area east of SB-26, and a Notice of No Further Action was
provided by NCDEQ in September 2005. As such, SVOC concentrations in soil in
the vicinity of SB-26 do not extend to the east beyond the parking area.
Neither benzo[a] anthracene, benzo[a]pyrene, benzo[b]fluoranthene, nor dibenzo[a,h]
anthracene were used in industrial processes at this facility. According to the Agency
for Toxic Substances and Disease Registry (ATSDR), PAHs are contained in asphalt
paving used in road construction. Also, it is common for natural areas along parking
lots, roads, and highways to contain elevated PAHs (Pan at al. 2009, Pathirana et al.
1994, and Mahler et al. 2010). Because the source of PAHs detected in shallow soils at
the Site likely originated from the asphalt pavement initially covering the work area,
Arcadis respectfully requests NCDEQ consideration whether these limited PAH
exceedances should be of an environmental concern for the facility.
Soil samples from borings SB-II through SB-NN were used to evaluate potential PCB
impacts related to transformers and LORAN equipment (Table 4). Concentrations of
PCBs at these locations were either not detected at concentrations greater than the
laboratory reporting limits, or were detected at concentrations less than the most
restrictive PSRGs.
Soil sample locations are shown on Figure 6. Laboratory analytical results are
summarized in Tables 3, 4, and 5. Laboratory analytical results are attached in
Appendix G.

3.3.4 Storage Building Impacts
Soil samples collected for evaluation of potential impacts related to the current Storage
and former Hazmat Storage buildings are shown on Figures 3, 5 and 6. Soil samples
from SB-WW and SB-XX were used to evaluate these locations (Tables 2, 3, and 5).
There were no reported exceedances of the most restrictive PSRGs for metals,
VOCs, or SVOCs in these samples.
Soil sample locations are shown on Figures 3, 5, and 6. Laboratory analytical results
are summarized in Tables 2, 3, and 5. Laboratory analytical results are attached in
Appendix G.
3.3.5 Storage Drum Impacts
Soil samples collected for evaluation of potential impacts following the removal of
approximately fifty-six (56) 55-gallon drums containing lube oil and water are shown on
Figures 5 and 6. Soil samples from borings SB-AB through SB-AS and monitoring
wells MW-5 and MW-6 were used to evaluate these locations (Tables 2, 3, and 5).
Concentrations of VOCs and SVOCs were not detected at concentrations exceeding
the most restrictive PSRGs. Concentrations of NCDEQ IHSB 14 metals were not
detected at concentrations exceeding the most restrictive PSRGs, with the exception of
the sample collected from the 2 to 2.5 foot interval at location MW-5, which had an
arsenic concentration of 0.99 mg/kg. This exceedance is delineated vertically by the
sample from location SB-AB, and horizontally by the samples from SB-AC, SB-AD,
SB-AF, and S13-27.
Soil sample locations are shown on Figures 5 and 6. Laboratory analytical results are
summarized in Tables 2, 3, and 5. Laboratory analytical results are attached in
Appendix G.
3.3.6 Unbiased Soil Sampling
Systematic random grid sampling was performed as described in the FSP to evaluate
soils where no current site structures are present, no former structures are known to
have been present, and where no visual evidence of potential impacts was observed
(see Figure 3). Field screening using the XRF reported lead concentrations less than
the lead screening level of 100 mg/kg in all unbiased soil samples (Table 1). Unbiased
soil samples were sent for laboratory analysis of lead. There were no reported
exceedances of the most restrictive PSRG of 270 mg/kg.

3.4 Groundwater Sample Results
Groundwater sampling was performed during ISE activities conducted between June
17 and June 23, 2014. An additional round of groundwater sampling was performed on
September 16 and 18, 2014. Analytical results from these sampling events are
included in Tables 7, 8, and 9 for metals, VOCs, and SVOCs, respectively. In all
samples collected during these groundwater monitoring events, analyzed constituents
were either not detected at concentrations greater than the laboratory's reporting limit,
or were detected at concentrations less than the Title 15A of the North Carolina
Administrative Code (NCAC) 2L Groundwater Standards ( 2L Standard) and/or the
Interim Maximum Allowable Concentrations (IMAC) with the following exceptions:
Dissolved thallium was detected at a concentration of 0.67 J micrograms per liter
(Ng/L) in MW-5 in the sample collected in June 2014, exceeding the IMAC of 0.2
pg/L. However, thallium was not detected in this well during the September 2014
sampling event. Total thallium was detected at concentrations of 1.9 J pg/L in the
sample collected from Monitoring Wells MW-12 in September 2014. These
concentrations were less than the federal drinking water standard (maximum
contaminant level [MCL]) of 2.0 pg/L, which can be used as a surrogate regulatory
criterion because a 2L Standard does not exist for thallium.
The samples collected from Monitoring Well MWA2 in June 2014 had
concentrations of dissolved manganese (66 pg/L) and total manganese (63 pg/L)
that exceeded the 2L Standard of 50 pg/L. The 2L Standard is not health -based,
but rather based on taste; it is equivalent to the secondary MCL. If the USEPA Tap
Water RSL of 400 pg/L is adjusted based on a target hazard quotient of 0.2 as is
used by NCDEQ to derive PSRGs, a health -protective groundwater concentration
of 80 pg/L is derived and none of the detected manganese concentrations are
greater than this health -based concentration. Therefore, it is unlikely that if the
water were used as a potable water supply, adverse health effects would occur.
Monitoring well locations are shown on Figure 2. Groundwater elevations for the Site
are summarized in Table 6. Laboratory analytical results from groundwater samples
are summarized in Tables 7 through 9. Laboratory analytical reports for groundwater
samples are attached in Appendix G.

4. Conclusions and Recommendations
The results of ISE activities completed at the Site indicate that environmental impacts
exists at the Site at levels not posing a risk with respect to the current and anticipated
future industrial land use.
The low level metals exceedances of arsenic and manganese remain below industrial
PSRGs as well as being below the background levels typical of North Carolina. One
shallow soil boring location exceeded the Protection of Groundwater level for lead;
however, this level is below the residential and industrial PSRGs and is delineated
horizontally by surrounding soil borings and vertically by the sample collected in the
interval immediately below. Elevated levels of hexavalent chromium were observed at
two locations at concentrations which were less than both the Industrial PSRG and the
Protection of Groundwater PSRG.
Concentrations of PAHs were observed in the vicinity of the on -Site buildings which
exceeded the most restrictive PSRGs; however, only two locations exceeded the
Industrial PSRG. The close vicinity of the sample locations to the Site buildings and/or
asphalt parking lots likely contributed to the elevated PAH concentrations observed
within the shallow surrounding soils.
Arcadis is pleased to submit this SIR to the NCDEQ for your review, and based on the
information contained herein, respectfully requests your approval of No Further Action
status for the Site under the NCDEQ Inactive Hazardous Sites Program.

General Notes:
All concentrations are in micrograms per kilogram ug/kg.
Concentrations compared to North Carolina Department of Environment and Natural Resources (NCDENR) Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs).
Appropriate Removal/Remedial Action Objectives (RAOs) will be presented in the Engineering Evaluation/Cost Analysis (EE/CA).
< denotes the result was not detected above the indicated detection limit.
Footnotes:
- Preliminary health -based soil remediation goals (PSRGs) adapted from the May 2014 United States Environmental Protection Agency (USEPA) Regional Screening
Tables (RSL.) http://www.ei)a.aov/reg3hwmd/risk/human/rb-concentrationtable/GenericTables/index.htm
2 - Developed using a soil leachate model using default values appropriate for North Carolina.
4 - Based on North Carolina Interim 2L as target groundwater concentration.
8 - The SRG is based on USEPA policy for cleanup of PCBs at Superfund Sites. The Branch is currently reviewing the PCB remediation goal policy and may issue further guidance at a later date.
Acronyms and Abbreviations:
C The PSRG is based on the carcinogenic endpoint and corresponds to an excess lifetime cancer risk of 1 in 1,000,000.

Table S. Soil Analytical Results, Semi -Volatile Organic Compounds
U.S. Coast Guard LORSTA Carolina Beach, Carolina Beach, North Carolina.
General Notes:
All concentrations are in micrograms per kilogram ug/kg.
Concentrations compared to North Carolina Department of Environment and Natural Resources (NCDENR) Inactive Hazardous Sites Branch (IHSB) PreliminarySoil Remediation Goals (PSRGs).
Appropriate Removal/Remedial Action Objectives (RAOs) will be presented in the Engineering Evaluation/Cost Estimate Analysis (EE/CA).
Bolded and shaded values indicate results exceed one or more PSRGs listed.
Footnotes:
1 - Preliminary health -based soil remediation goals (PSRGs) adapted from the May 2014 United States Environmental Protection Agency (USEPA) Regional Screening
Tables (RSL.) http://www.epa.gov/reo3hwmd/risk/human/rb-concentrationtable/GenericTablestindex.htm
2 - Developed using a soil leachate model using default values appropriate for North Carolina.
3 - Based on North Carolina 2L as target groundwater concentration.
4 - Based on North Carolina Interim 2L as target groundwater concentration.
Acronyms and Abbreviations:
B Compound found in the sample and the associated blank.
C The PSRG is based on the carcinogenic endpoint and corresponds to an excess lifetime cancer risk of 1 in 1,000,000.
Csat Soil Saturation Concentration
(DUP) Duplicate sample
ft bgs Feet below ground surface
J The compound was positively identified; however, the associated numerical value is an estimated concentration only.
M Contaminant is a mutagen.
M" Manual Integrated Compound
N The PSRG is based on the non -carcinogenic endpoint and corresponds to a hazard quotient of 0.2.
I{ NA Not available/not analyzed
R The sample results are rejected. Additional details regarding rejected data can be found in the data validation reports.
U The compound was analyzed for but not detected. The associated value is the compound quantitation limit.
UB Compound considered non -detect at the listed value due to associated blank contamination.
UJ The compound was not detected above the reported sample quantitation limit. However, the reported limit is approximate and may or may not represent the actual limit of quantitation.
