Brownfields Project Number 13008-09-86
WR Project No. 02090017.20
Dear Ms. Thompson:
WithersRavenel, Inc. (WR) has completed this work plan to perform limited environmental site
assessment (ESA) activities for the above referenced property. This work plan has been developed
to address concerns identified during Phase I ESA activities conducted by WR for the referenced
site. The work plan/proposal outlines our proposed scope of services.
BACKGROUND
WR previously completed a Phase I Environmental Site Assessment (ESA) for the subject site in
February 2009. After completion of the Phase I ESA and after reviewing all of the site information,
including the investigation reports by other consultants, WR concluded that additional assessment
should be considered due to possible contamination from either the initial hosiery mill operations
that were not investigated during the initial environmental study or the continued operation of the
mill as a sock manufacturing facility subsequent to the initial environmental study.
WR understands that an application for Brownfields was submitted to the NCDENR (now the
NCDEQ) in June 2009 and found eligible for entry. In September 2009, an “Additional Assessment
Requirements” letter was completed by Ms. Sharon Eckard of the NCDENR and provided to the
Town of Pilot Mountain declaring next steps in the process to conduct assessment activities to
determine how the site can be made safe for its intended use.
In December 2011, the NCDENR issued a letter that changed the status of the site from “inactive
eligible” to “No Further Interest” due to the inactivity on the project.
WR was contacted by Homer Dearmin in late 2013 to complete an updated application for
submittal to the Brownfields program for eligibility. The application was submitted and received in
March 2014. WR, Mr. Homer Dearmin, and Ms. Sharon Eckard with the NCDENR, Division of
Waste Management, Brownfields Program (Brownfields Program) participated in a conference call
regarding development of a scope of work for completing assessment activities of the property per
the 2009 letter issued by Ms. Eckard. WR understands that the Town did not pursue this work at
that time because of the cost associated.

On May 12, 2016, WR and representatives of the Brownfield Program, including Ms. Sharon Eckard,
Mr. Bruce Nicholson, and Ms. Joselyn Harriger, conducted a conference call to discuss the current
status of the site and the additional information needed to allow this site into the Brownfield
Program. The result of the meeting clarified that the NCDEQ wants an evaluation of the soil,
groundwater, and soil vapor in various areas of the site. Particular areas mentioned included the
areas near the current Otay, LLC/Sports Solutions property, the former dye and wet processing
areas, the former boiler room, and the existing boiler room building. Discussion was also made
about the previous sampling information on the site not being of proper detection limit when
compared to their respective “2L Standards” as defined by NCAC Title 15A, Subchapter 2L, Section
.0202 (Water Quality Standards for Class GA Groundwater).
SITE CONDITIONS/USE
Current Area - Otay, LLC/Sports Solutions
WR has completed a recent site visit and in turn has summarized the current processes of the
present Otay, LLC/Sports Solutions area. Sports Solutions is a textile manufacturing facility. They
complete sock manufacturing and finishing, headband and wristband manufacturing and finishing,
several imprinting applications, and screen printing. After review of the operations and facility
construction, it is our opinion that this facility does not use or produce significant volumes of
chemical waste that would create any additional subsurface contaminants.
According to Mr. Josh East, who is the Director of Operations, Sports Solutions does not dye
currently nor have they completed any dyeing operations at any time since they have occupied the
building. Their “wet processing” is actually a sock washing area used to scour, soften, and whiten
socks. There was a new 6” line installed for their waste water to go directly into the city sewer. Mr.
East stated that they are not equipped to complete dyeing at the facility as you need water heated
to a certain temperature to complete the dyeing operations. He stated that they would have to
invest several thousands of dollars to acquire the equipment in order to complete this work. The
facility contains a Doming /Print Room, Finishing/Screen Printing area, and a sock washing area
(Please refer to Figure 3 for the location of structures and material).
Mr. East has provided a full chemical list and comprehensive chemical use and process explanation
of the onsite operations, which has been in as Appendix A. The corresponding MSDS sheets are
provided in Appendix B. After a recent site reconnaissance conducted by WR, and a review of this
material, it does not appear that chemicals in large quantities, excluding the preceding 55-gallon
and 30-gallon drums, are being used or stored on the site. See Appendix C for current pictures of
the Doming /Print Room, Finishing/Screen Printing area, and a sock washing area areas to correlate
to the following information:
1) Photo #5 - The photo labeled "Oil for knitting machines" shows the storage and recycling of
the knitting oil. The 55-gallon drum on the right of the photo shows new oil that is available
for use for the machinery. The small 30 gallon drum is where they pour the used oil, then
filter it through the pump on the platform above and discharge the filtered oil back into a
second 55 gallon drum until needed. The filter pump uses a standard automobile filter.

2) Photo #6 - The photo labeled "Screen Print Dark Room" shows the dark room that is used
for creating screens with an emulsion product. This room is typically used for cleanup of the
screens and they are washed in the sink on the left hand of the photo. This sink drains
directly to the town sewer system.
3) Photo #7 - The photo labeled "Screen printing area" shows the equipment and area where
the screens are used to apply designs to the textile garment.
According to this information, it does not appear that additional investigation of current conditions
appears warranted when compared to historical operations of the facility.
Historical Areas
Based on review of available files, environmental databases, representative interviews, and site
observations thus far, WR identified the following potential concerns addressed in this work plan
(Please refer to Figures 1, 1A, and 2 through 4 for the location of structures and material):
Chemical Storage & Air Filtration System
• Chemicals associated with dyeing operations have been used and stored on the subject
property. Signs and placards were noted on the detached boiler room and vacant warehouse
exterior walls.
An air/water filtration system to remove lint from the air was located inside the warehouse
with at least three floor drains and a possible trench.
Former Shop Areas
Two former shop areas were noted on a former site plan sketch of the building acquired
during the Phase I ESA in 2009.
Maintenance/Repair Area
• The basement had been used as a maintenance and repair area for hosiery machinery.
Multiple Trench Drains and Floor Drains
Two large trench drains filled with concrete were noted in the central western portion of
the site during the Phase I ESA. Several floor drains were also noted in the building.
Boiler Rooms
• The hosiery operation utilized two boiler rooms, one located within the building and another
in the detached boiler room structure, which would have utilized petroleum fuels. WR
observed a large containment basin adjacent to the detached boiler room structure.
According to Mr. Harris, the former subject property owner, a 7,500 to 10,000-gallon
petroleum AST had been located in this area. Obvious staining was observed near the piping

Brownfields Project Number 13008-09-86 Page 4 of 6
inside the boiler room building. Potential contamination associated with fueling overfills and
possible leaks should be investigated in these areas.
Former Dye House
• The Dye House formerly contained trench-style floor drains that ran along the eastern sides
of the room and discharged via piping into the sanitary sewer, after running through a lint
filter. The floor drains have been filled in with concrete by the former owner, Carolina Caro
Associates, LLC. Potential contamination associated with possible pipe leaks and the storage
of chemicals in this area should be investigated.
Residential Heating Oil ASTs
• WR observed two 250-gallon ASTs adjacent to the eastern most residential structure.
Staining and odors typical of petroleum products was observed on the oil filter and the ground
surface below the filter. Additional petroleum staining was observed on the ground surface
in close proximity to the ASTs.
Existing Groundwater Monitoring Wells
• A groundwater monitoring well is located on the northern portion of the site. A second well
was discovered east of the detached boiler room, near the containment wall of the former
AST. No indication of the origin of the well was revealed through the EDR report. It appears
that three temporary wells were installed during the UST Closure activities. The third well,
located near the southwest corner of the site, could not be located during Phase I ESA
activities.
SCOPE OF WORK
WR has completed this work plan in an effort to satisfy the requirements for the Brownfields
Agreement explained in the September 2009 “Additional Assessment Requirements” letter
provided by the Brownfields Program. In order to address each area specifically, WR has completed
the proposed sampling locations and analysis table in the appendices for review purposes. Please
refer to Table 1 when reviewing the following information.
The proposed assessment activities are intended to provide a general screen for possible impacts
of the subject property by the above referenced potential sources of contamination rather than a
detailed investigation to define the degree and extent of contamination from a known contaminant
source. Therefore, this scope of work may not define the extent of contamination at the site and is
not intended to satisfy all regulatory requirements for the site. WR has developed the following
scope of work to complete assessment activities:
1. WR will use either a GeoProbe direct push drill rig or a decontaminated steel hand auger to
advance the soil borings around the areas identified in Table 1. The borings will be advanced
to a target depth of 2 feet below land surface (bls) unless obvious contamination is observed
or refusal is met in stiff material. The borings completed inside the facility, for instances at the
former trench locations, will be completed with a hammer/core drill and hand auger. Soil

Former Amos & Smith Hosiery Mill Property
Brownfields Project Number 13008-09-86 Page 5 of 6
samples will be collected at the 2-foot interval beginning at the surface. The soil sample will
be screened for organic vapors using a TVA-1000B Toxic Vapor Analyzer or a Flame or Photo
Ionization Detector (PID) and Organic Vapor Analyzer (OVA) combination.
2. In the vicinity of the detached boiler room and the former residential ASTs, WR will install
three soil borings in each area to 2 ft. Field screen all borings and select a minimum of one
sample per area for laboratory analysis. If field screening (PID readings, visual and olfactory
observations) indicate impacts in more than one sample, submit all samples from that area for
laboratory analysis.
3. Soil samples from the site will be collected from 0.5 to 2 feet below land surface (soil samples
for VOC analysis should not be collected from the upper 6 inches of the soil column) and
submitted for laboratory analyses of volatile and semi-volatile organic compounds
(VOCs/SVOCs) by EPA Methods 8260B plus Tentatively Identified Compounds (TICS) &
8270C plus TICS, respectively, as well as hazardous substance list (HSL) metals by EPA Method
6020/7471. The HSL list includes antimony, arsenic, beryllium, cadmium, chromium, copper,
lead, manganese, mercury, nickel, selenium, silver, thallium, and zinc. WR will also advance two
soil borings in a remote area on site (outside the building) in order to collect background
samples for HSL metals by EPA Method 6020/7471 for site comparisons.
4. Five temporary Type II monitoring wells will be installed in the referenced areas noted in Table
1 using the GeoProbe drill rig modified to allow air rotary drilling operations. The monitoring
wells will be constructed of a 2-inch diameter PVC riser connected to a 15 to 20-foot section
of 2-inch diameter, 0.010-inch slotted PVC screen. WR estimates that the wells will be
completed to 40 feet bls. The annular space around the wells will be filled with #2 filter sand
up to approximately 1 to 2 feet above the top of the screen, if a natural sand pack does not
occur. A 1 to 2-foot thick bentonite seal will be placed over the sand pack and hydrated. Upon
receipt of analytical data, it will be decided to either abandon the monitoring wells or complete
them as a permanent well. WR understands that shallow bedrock may be present on the site
due to the formation of this area. Therefore, a larger drill rig may be required to install the
wells.
5. The monitoring wells, to include the existing and newly installed, will be developed, purged,
and sampled. Groundwater samples will be collected and submitted for analysis by EPA
Methods 8260B plus TICS & 8270C plus TICS and aniline, respectively, as well HSL metals by
EPA Method 6020/7470. WR will collect a sample of the existing well located on the northern
portion of the site between the facility and Main Street installed in 1990 and the well to the
east of the detached boiler location. All laboratory samples will be submitted for “standard”
turn around times. Additionally, the groundwater sample from the wells installed near the
former dye house, stated to contain chlorine/peroxide storage, will be field-tested for chloride
concentrations using a Hach® assay kit. Discussions will be made with the lab to set laboratory
detection limits below 2L standards, where possible.
6. WR will complete a receptor survey of the surrounding area according to the “Brownfields
Property Receptor Survey” by collecting information on possible receptors that include
property and Building characteristics, surrounding property land use, subsurface
structures/utilities, water supply wells, and surface water bodies and wetlands. WR will also

Former Amos & Smith Hosiery Mill Property
Brownfields Project Number 13008-09-86 Page 6 of 6
collect additional related information including public water supply availability, location of any
nearby well head protection areas, and surrounding property owners and occupants.
Soil vapor sampling will initially be withheld from this work plan to analyze the results from the soil and
groundwater samples collected on the Site. If the soil/groundwater results indicate impacts above vapor
intrusion screening levels, WR will submit a separate work plan for NCDEQ approval.
QA/QC
All sampling activities will be performed by properly trained environmental professionals. Sampling
personnel will don new disposable gloves for each sampling location to prevent contact with skin
and prevent cross contamination of samples. Sampling equipment will be decontaminated prior to
advancement of each borehole. All samples will be collected directly into laboratory prepared
containers, immediately placed on ice in a cooler, and transported under chain of custody to a NC
certified laboratory for analysis.
WR will include at least one duplicate for all samples and analysis collected and at least one trip
blank for groundwater. The duplicate samples will be chosen from the sample collected exhibiting
an obvious sign of contamination. WR will request Level II QA/QC from the laboratory that will be
analyzing the samples.
REPORT PREPARATION
Upon receipt of laboratory analytical data for the samples collected, WR will prepare a report
summarizing the methodology and results of the field sampling and tank removal activities
conducted as outlined in this work plan/proposal. The report will include a site location map and a
site plan showing pertinent site features. The report will be reviewed by WR senior personnel for
quality assurance.
SCHEDULE
WR is prepared to complete this project within approximately four to eight weeks (based on
selected laboratory reporting time) of authorization to proceed. The delivery of the report will be
contingent on the timely receipt of soil and groundwater assessment data from the subcontract
laboratory and availability of the drilling contractor.
WR appreciates the opportunity to submit this proposal. If you have any questions or desire further
information, please call us at 469-3340.
Sincerely,
WithersRavenel
