1.0 INTRODUCTION
Terracon Consultants, Inc. (Terracon) conducted an asbestos in soil survey of the above
referenced site in Davidson, North Carolina. The survey was conducted between July 27-29,
2015 and September 9-10, 2015 by a North Carolina accredited asbestos inspector in general
accordance with Terracon Proposal No. P71150239 dated July 30, 2015 and supplemental
proposal numbers P71150239r1a and P71150239r2 dated August 20, 2015 and September 25,
2015 and asbestos sampling necessary to characterize the extent of asbestos contamination
present at the Davidson Depot site.
We understand this asbestos survey was requested due to the planned development of the
above referenced site to address potential asbestos soil contamination.

3.0 FIELD ACTIVITIES
The survey was conducted by North Carolina accredited asbestos inspector Alex Manzanarez
(Accreditation No. 12617). The survey was conducted in general accordance with the sample
collection protocols established in USEPA 40 CFR Part 763 Subpart E 763.86, AHERA and
industry practices. A summary of survey activities is provided below.
3.1 Visual Assessment
Survey activities were initiated with visual observation of the property to identify areas
suspected of having deposits of asbestos debris. Terracon picked different locations to test the
soil inside of the area that will be developed. Areas currently planned for significant undercut by
the current development plan were specifically targeted. Terracon also chose locations that
were not expected to have deposits of asbestos debris for comparison.
3.2 Physical Assessment
A physical assessment of each sample location of suspect asbestos-containing materials (ACM)
was conducted to assess the friability and condition of the materials. A friable material is defined
by the USEPA as a material which can be crumbled, pulverized or reduced to powder by hand
pressure when dry. Friability was assessed by physically touching suspect materials.
3.3 Sample Collection
Based on results of the visual observation of the soil borings, bulk soil samples of suspect ACM
were collected in general accordance with USEPA AHERA and industry accepted sampling
protocols. Please refer to the attached drawing (A-2A) in Appendix C for sample locations.
The selection of sample locations and frequency of sampling were based on Terracon’s
observations and the assumption that like materials in the same area are homogeneous in
content.
Terracon collected forty-four (44) soil samples from nineteen (19) areas of suspect ACM on the
site. A summary of suspect ACM samples collected during the survey is included as Appendix
B.
3.4 Sample Analysis
Soil samples were submitted under chain of custody to EMSL Analytical, Inc. (EMSL) of
Cinnaminson, New Jersey for analysis by ASTM D7521: Standard Test Method for the
Asbestos in Soil Survey Report

Determination of Asbestos in Soil. The percentage of asbestos, where applicable, was
determined by weighted asbestos concentration.
4.0 REGULATORY OVERVIEW
The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiber emissions and
asbestos waste disposal practices. The asbestos NESHAP regulation also requires the
identification and classification of existing ACM according to friability prior to demolition or
renovation activity. Friable ACM is a material containing more than 1% asbestos that, when dry,
can be crumbled, pulverized or reduced to powder by hand pressure. All friable ACM is
considered regulated asbestos containing material (RACM).
The asbestos NESHAP regulation classifies ACM as either RACM, Category I non-friable ACM
or Category II non-friable ACM. RACM includes all friable ACM, along with Category I and
Category II non-friable ACM that has become friable, will be or has been subjected to sanding,
grinding, cutting or abrading, or ACM that has a high probability of becoming or has become
crumbled, pulverized, or reduced to powder in the course of renovation or demolition activity.
Category I non-friable ACM are exclusively asbestos-containing packings, gaskets, resilient
floor coverings, resilient floor covering mastics and asphalt roofing products that contain more
than 1% asbestos. Category II non-friable ACM are all other non-friable materials other than
Category I non-friable ACM that contain more than 1% asbestos. Category II non-friable ACM
generally includes but is not limited to cementitious material such as: cement pipes, cement
siding, cement panels, glazing, mortar and grouts.
The OSHA Asbestos standard for construction (29 CFR 1926.1101) regulates workplace
exposure to asbestos. The OSHA standard requires that employee exposure to airborne asbestos
fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air (0.1 f/cc). The OSHA
standard classifies construction and maintenance activities which could disturb ACM, and
specifies work practices and precautions which employers must follow when engaging in each
class of regulated work. States which administer their own federally-approved state OSHA
programs may require additional precautions.
In the state of North Carolina, the Health Hazards Control Unit (HHCU) regulates asbestos
activities. The NC HHCU requires that any asbestos-related activity conducted in a public
building be performed by personnel licensed by NC HHCU. RACM must be removed prior to
renovation or demolition activities which will disturb the materials. The owner or operator must
provide the NC HHCU with written notification of planned removal activities at least 10 working
days prior to the commencement of asbestos abatement activities. Removal of RACM must be
conducted by a State of North Carolina licensed asbestos abatement contractor. In addition,
third party air monitoring must be performed following the abatement.

5.0 FINDINGS
Asbestos was identified in soil samples of varying depths throughout the site. Please refer to
Appendix A for specific borings, sample depths and sample locations. Boring logs are included
in Appendix D.
Based on the results of the asbestos sampling at this site, Terracon recommends that soil
contaminated with asbestos, if excavated, be removed and disposed as an asbestos-containing
material. Excavation and grading on the site should be performed by an experienced asbestos
abatement contractor using North Carolina accredited asbestos workers and supervisors.
Specific technical work procedures and an asbestos monitoring plan should be developed for
this work. Terracon also recommends that once the asbestos soil removal is complete, a
geotextile liner could be installed with a minimum 12” cap of clean soil. The geotextile liner
would serve as a demarcation point between clean and potentially asbestos-contaminated soil.
6.0 LIMITATIONS/GENERAL COMMENTS
This asbestos soil survey was conducted in a manner consistent with the level of care and skill
ordinarily exercised by members of the profession currently practicing under similar conditions
in the same locale. The results, findings, conclusions and recommendations expressed in this
report are based on conditions observed during our survey of the land for development. The
information contained in this report is relevant to the date on which this survey was performed,
and should not be relied upon to represent conditions at a later date. This report has been
