Dear Collin:
In accordance with our recent telephone conversation, please find attached a copy of a Phase I
Environmental Site Assessment Report for the proposed Caroline Courtyard development in
Lincolnton, North Carolina. The scope of work for this environmental assessment was completed
in accordance with the American Society of Testing and Materials (ASTM) Standard Practices
for Environmental Site Assessments: Phase I ESA Process (ASTM Designation: E1527-13).
The Phase I Environmental Assessment identified two (2) off-site Recognized Environmental
Conditions (RECs) for the subject site. The two RECs that were identified in Phase I report are:
1.Former General Marble Site (NONCD0001069): Based on a 2014 ground water monitoring
report prepared by the Responsible Party’s consultant EnSafe, Inc., PCE that was released into
the ground water from the General Marble property has migrated down gradient in a southwest
direction from their facility toward Walker Branch and onto the subject (Barkley) property that
is being targeted for the Carolina Courtyard development project.

2.Textile Piece Dyeing Facility (NONCD0002587): Correspondence obtained from the
NCDENR archives shows that the most recent ground water sampling data that has been
submitted for this incident dates back to September 30, 2010. The ground water sampling
results from this sampling event show that elevated levels of PCE were still reported on-site.
Furthermore, five (5) of the eleven (11) ground water monitoring wells that were sampled in
2010 reported higher concentrations of PCE than concentrations that were observed in the
same wells from 1993-1996.
In addition to the Phase I report, we are also submitting the results of recent ground water
sampling that was performed on seven (7) monitoring wells located on the subject (Barkley)
property that were installed in 2001 as part of the General Marble incident. The results of ground
water analyses indicate that dissolved phase chlorinated compounds were detected in each of the
ground water samples that were collected from the seven monitoring wells on September 3.
2014. Tetrachloroethene (PCE), cis-1,2-dichloroethene and trichloroethene were all reported at
concentrations that were above their NCAC 2L Ground Water Standards. The ground water
sampling results also indicate that the plume of chlorinated compounds now covers a larger
aerial extent of the undeveloped Barkley property when compared to sampling results performed
in 2001 during the General Marble site assessment.
Finally, please find attached a letter from The BTR Communities Group, LLC and a conceptual
site plan that discuss and illustrate the details of the proposed development. As you will see, this
is a very meaningful project for the Lincolnton community and we look forward to working with
your office to address the environmental issues that are associated with the development of this
project.
