EXHIBIT "A"
SCOPE OF WORK
Limited Phase II Subsurface Investigation:
A site-specific health and safety plan (HASP) will be prepared prior to initiating field activities. The development of
the HASP is required by the Occupational Safety and Health Administration (OSHA) under Hazardous Waste
Operations & Emergency Response 29 CFR 1910.120. The HASP will include information about chemicals that may
be encountered on the property, health and safety procedures, and emergency response procedures.
It is anticipated that up to sixteen borings will be advanced on the subject site utilizing direct push technology (e.g.,
Geoprobe®). The borings will be throughout the subject site to a depth of thirty feet, refusal or groundwater'
whichever is encountered first. Visual and olfactory senses and a photoionization detector (PID) will be utilized
during field activities to field screen the samples for potential contamination. One soil sample will be collected from
each boring from either the top of the boring or the area that the field screening indicates is die most impacted.
A temporary well point (TWP) will be installed in up to six of the borings to facilitate collection of a groundwater
sample. No groundwater sample will be collected if free product is detected in the temporary well point. If free
product is detected in the boring, Hillman will attempt to collect a sample of the product for hydrocarbon fingerprint
analysis.
All soil and groundwater samples will be analyzed for constituents associated with waste oil including: volatile
organic compounds (VOCs) by EPA method 8260, semi-volatile organic compounds (SVOCs) by EPA method 8270,
pesticides and polychlorinated biphenyls (PCBs) by EPA method 8081 and 8082, respectively, and TAL metals. All
soil will be containerized in laboratory-supplied glassware, which will be sealed and labeled. Once sealed and
labeled the sample containers will be placed in a sample cooler and transported to a North Carolina licensed
laboratory under chain-of-custody-protocol. The samples will be analyzed on a standard 10 business day turnaround
time (TAT).
The area required for the borings must be free and clear of any obstructions, debris, etc.
Concrete Sampling:
As requested, Hillmann will collect concrete samples to determine if the concrete at the subject site is impacted.
Concrete samples will be collected in accordance with the North Carolina Department of Environment Natural
Resources (NCDENR) protocol. Sampling locations will be based on field judgment and will be spread out through
all buildings on the subject site. Based on the above referenced information and the NCDENR protocol, Hillmann
will collect one sample from each location for a total of 10 samples.
All concrete samples will be collected in laboratory supplied containers and transported, under chain of custody
protocol, to a North Carolina certified laboratory. All samples will be analyzed for polychlorinated biphenyls (PCBs)
and polycyclic aromatic hydrocarbons (PAHs) on a standard 10 business day turnaround time.
Upon completion of site activities and receipt of sample analytical data, a Site Investigative Report will be submitted
documenting the project activities. The Site Investigative Report will include a summary of work conducted, figures,
table, laboratory analytical data package, and conclusions/recommendations.
./. All samples will be collected in accordance with Appendix A and Appendix B of the Inactive Hazardous Site
"* Program's (IHSP's) Guidelines for Assessment and Cleanup (January 2014 version).
Only samples collected and analyzed will be invoiced. If field conditions warrant less samples may be collected and
analyzed than described above.
