The next issue is fill dirt. Brownfield will require confirmation of clean fill prior to importing on the property. We can
discuss this more next week, but it might be helpful if you knew the ballpark quantity of likely import.

Good to hear from you Sean. All is well and very busy in brownfields. Glad the project is moving forward. Next week
on Thursday or Friday would be preferred for me. I will need time to review the project and get reacquainted with
assessment that has been done to date.

Per your email below, you will need to import and move soil around on the brownfields property. Do you anticipate
exporting soil off the brownfields property?

I am available Thursday or Friday (27/28) from 8:30-3 pm. Let’s schedule a conference call during this window.

Thank you.

Ms. Minnich,

I hope this finds you well, the City of Charlotte D-B project for the I-85 connector is moving along nicely. They have
determined their preferred alternative (please see attached). As indicated in red, most of the site work will require
filling, with the exception of a few minor cuts long Research Drive and for sidewalks etc. on the northern edge of the
future roadway.

The purpose of this email is to request a little of your time to discuss potential brownfields related issues at the site
including soil management, acquisition, Phase II, potential dewater etc. If there is a time we can speak on these
topics that would be much appreciated.

Thanks in advance.

Ms. Minnich,
As an add-on from the email chain below I was wondering if there were any historic Phase II or delineation type reports or
findings. As we narrow our preferred corridors (down to two potential alignments presently) we want to determine any
potential cut/fill or dewatering issues that could arise during construction for further costing considerations. The area ofinterest would probably be the northern property edge at this time.

Any assistance on this would be greatly appreciated for our efforts. Thanks so much and in advance.

1. BACKGROUND INFORMATION
The project is located at Research Drive and Louis Rose Place, near I-85 between Research
Drive and JW Clay Boulevard in Charlotte, Mecklenburg County, North Carolina (Figure 1). ECS understands that the subject site is located on a larger property known as the Polymer
Center of Excellence facility and/or the Reeves Site. Tetrachloroethylene impacts have been
identified in the groundwater at this property. A Brownfields Agreement is in place for this property through the North Carolina Department of Environmental Quality (NCDEQ) Brownfields
Program.
Based on the scope of work provided by HDR Engineering Inc. of the Carolinas (HDR), ECS
proposed to complete a Phase II Assessment to further define and delineate any residual contamination that may exist on-site.
2. FIELD ACTIVITIES
The environmental services originally consisted of collecting six soil samples, two surface water
samples (SW-1 and SW-2), and thirteen groundwater samples from six temporary wells (TW-1 through TW-6) and seven pre-existing monitoring wells (MW-3, MW-4, MW-5A, MW-5B, MW-
5C, MW-6, and MW-7. ECS discovered an eighth monitoring well (MW-8) during the site visit,
and three of the wells could not be sampled (MW-4, MW-5A were dry and MW-7 was flush mounted and in an area of heavy vegetation and could not be located), so a total of eleven
groundwater samples were collected. The soil samples were collected and the temporary wells were installed using a Geoprobe® drill. The subcontractor used for this project was 3-D Environmental. Photographs of the site and site work are included in Appendix A.
Prior to commencing with field activities, ECS contacted North Carolina One Call and Priority Locate to locate/mark public utilities at the site. Required separation distances between
subsurface activities and marked utilities (typically 30-inches) were maintained during the field activities.

As part of this assessment, ECS prepared a site-specific health and safety plan (HASP) for the site. The HASP documented the known or suspected hazards, applicable personal protective
equipment (PPE) of site personnel, and emergency response procedures. Prior to commencing
with field activities, ECS and its subcontractors and applicable site personnel reviewed the site-specific HASP.
2.1 Soil Sample Collection

Each soil boring was advanced by hydraulically driving a five-foot long, 1.5-inch soil sampling probe into the soil. Prior to advancing each boring, the down hole equipment and Geoprobe® drill rig were decontaminated utilizing a high pressure steam cleaner that utilized municipal
water. The down hole equipment and drill rig were decontaminated to prevent cross-contamination between boring locations. The soil sampling probe is lined with a disposable clear plastic tube, which is replaced with each five-foot interval. After the probe is driven, the clear
plastic tube filled with soil is removed from the probe. The clear plastic tube is then cut open to remove the soil. ECS visually classified the soils collected from each boring and screened the
soil samples for relative levels of volatile organic vapors using a field screening instrument.

ECS Project: 49:2562
September 28, 2016
Boring logs, which include descriptions of the soils encountered and field screening results, were prepared for each boring and are included in Appendix B. Upon completion, each boring
was properly abandoned.
Each soil sample collected in the field was transferred into a new, clean resealable bag (half full),
and the bag placed in a warm location. Approximately ten minutes after the time of collection, the bag was opened slightly and the probe of a (Rae Systems Mini Rae 3000) was inserted, and the bag immediately resealed using finger pressure. The meter of the PID was monitored and the
reading recorded. The recorded PID responses are presented on the boring logs included in Appendix B.
The soil samples were placed into laboratory prepared containers. The sample containers were labeled with ECS project number, sample identification, sample date and time, and requested
analytical analysis. The containers were placed into protective packaging material and placed
into a cooler with ice to maintain the samples at approximately 4° Celsius (C°). The samples
were submitted to Prism Laboratories located in Charlotte, North Carolina (North Carolina Certification # 402) for chemical analysis for Volatile Organic Compounds (VOCs) and Semi-
Volatile Organic Compounds (SVOCs) using EPA Method 8260 and 8270. ECS maintained
proper chain-of-custody (COC) procedures throughout the sample collection and transportation process. Copies of the COCs are included in Appendix C.
2.2 Groundwater Sample Collection
The temporary monitoring wells were installed in the borings drilled as discussed above. The
temporary wells were constructed with one-inch I.D. Schedule 40 PVC flush-threaded casing and screen. The PVC screen and casing was lowered into the open borehole. A ten-foot length of
slotted well screen with machined 0.010-inch slot widths and a threaded bottom plug were installed
at the bottom of each well. The screens were installed to a depth such that the screened interval intersected the estimated groundwater surface. The depths of the temporary wells ranged form 12
to 35 feet below ground surface (bgs). A solid section of PVC casing was placed above the
screened interval and extended to a point just below the ground surface. The annular space around each well was filled with washed and graded medium sand to approximately two feet above
the top of the screen. A minimum two-foot thick seal of bentonite was placed immediately above the sand pack where able. A temporary monitoring well construction diagram was prepared for each temporary monitoring well, which are included in Appendix B. The temporary wells were
sampled using a peristaltic pump with dedicated polyethylene tubing.
The pre-existing monitoring wells were purged by removing at least three well volumes or until
dryness twice. After the purging was completed, groundwater samples were collected from the wells. Purging and sampling was accomplished using either a peristaltic pump with dedicated
polyethylene tubing or a new disposable polypropylene bailer. Immediately after collection, the
groundwater samples were transferred into sample containers provided by the laboratory.
The groundwater samples were placed into laboratory prepared containers. The sample
containers were labeled with ECS project number, sample identification, sample date and time,
and requested analytical analysis. The containers were placed into protective packaging
material and placed into a cooler with ice to maintain the samples at approximately 4° Celsius
(C°). The samples were submitted to Prism Laboratories located in Charlotte, North Carolina

(North Carolina Certification # 402) for chemical analysis for VOCs and SVOCs using EPA Method 8260 and 8270. ECS maintained proper COC procedures throughout the sample
collection and transportation process. Copies of the COCs are included in Appendix C.
2.3 Surface Water Sample Collection
The surface water samples were collected by lowering a laboratory prepared non-preserved glass container into the surface water at an area of low flow. The collected surface water
samples were then decanted into the laboratory prepared sample containers applicable to
analytical method.
The surface water samples were placed into laboratory prepared containers. The sample
containers were labeled with ECS project number, sample identification, sample date and time,
and requested analytical analysis. The containers were placed into protective packaging material and placed into a cooler with ice to maintain the samples at approximately 4° Celsius (C°). The samples were submitted to Prism Laboratories located in Charlotte, North Carolina
(North Carolina Certification # 402) for chemical analysis for VOCs and SVOCs using EPA
Method 8260 and 8270. ECS maintained proper COC procedures throughout the sample
collection and transportation process. Copies of the COCs are included in Appendix C.
3. LABORATORY ANALYSIS
Laboratory analysis of soil, groundwater, and surface water samples SS-1, SS-2, SS-2, SS-4, SS-6, TW-1, TW-5, SW-1, and SW-2 did not detect targeted analytes (VOCs or SVOCs) above
laboratory detection limits.
Laboratory analysis of soil and groundwater samples SS-5, TW-2, TW-3, TW-4, TW-5, and MW-
3, detected multiple VOCs above laboratory detection limits; however, the concentrations do not exceed the applicable North Carolina standards.
Laboratory analysis of groundwater samples MW-5B, MW-5C, MW-6, and MW-8 detected tetrachloroethylene (PCE) above the North Carolina 2L Groundwater Standard. These concentrations are generally consistent with the historical levels detected during the last
Brownfield groundwater monitoring event conducted in 2014.
A summary of the laboratory analytical results is included in Tables 1, 2, and 3. The laboratory
data sheets are included in Appendix C.
4. CONCLUSIONS
Based on the field observation and laboratory analytical results of the soil samples collected
during this assessment, ECS concludes the following:
•Groundwater was encountered at depths ranging from six to thirty feet bgs.
•Drilling refusal was encountered in one of the borings (SS-6) at an approximate depth of
twelve feet bgs.

•Impacts to soil or surface water were not identified in the samples collected.
•Laboratory analysis of groundwater samples detected targeted analytes (PCE) atconcentrations that exceed the North Carolina 2L Groundwater Standard in four of the pre-
existing monitoring wells, and at concentrations consistent with the levels previouslyidentified in the Brownfield Agreement. The concentrations are not above the North
Carolina vapor intrusion screening levels for non-residential sites.
5.RECOMMENDATIONS
Based on the results of the assessment, ECS recommends the following:
•Additional assessment does not appear necessary and is not recommended.
•ECS recommends that the current property owner be notified and that they submit a copy ofthe report to the North Carolina Brownfields Department for their records.
6.QUALIFICATIONS OF REPORT
The activities and evaluative approaches used in this assessment are consistent with those
normally employed in environmental assessment projects of this type. Our evaluation of site conditions has been based on our understanding of the site project information and the data
obtained during our field activities. Based on the field observation and laboratory analytical
