contractor will take into account wind speed, direction, and moisture content during the activities of
excavation, stockpiling, and loading for offsite disposal.
☒ Field Screening:
☒ Yes ☐ No
If yes, describe method; If no, explain rationale: Health and safety monitoring for VOCs using

observe soils to identify staining, odors, debris or other indications of contamination and verify that
all impacted soil is removed.
☒ Soil Sample Collection:
☒ Yes ☐ No
If yes, describe method (e.g., in-situ grab, composite, stockpile, etc.); If no, explain rationale:
Confirmation grab samples will be collected in each excavation from sidewalls (4 samples) and floor (1
sample) (personnel will not enter excavations to collect samples; a grab sample will be collected from
an excavation bucket containing soil from each sidewall and from the excavation floor) and analyzed
fro VOCs to confirm soil exceeding cleanup criteria have been removed. In addition, 1 composite
sample from each disposal rolloff and analyzed for TCLP VOCs to characterize the soil for disposal.
☒ Stockpile impacted soil in accordance with NCDENR IHSB protocol in the current version of
the “Guidelines for Assessment and Cleanup”, and providing erosion control, prohibiting
contact between surface water/precipitation and contaminated soil, and preventing
contaminated runoff. Explain any variances:

regulations, no contaminated or potentially contaminated soil may leave the site without approval
8
EMP Form ver.1, October 23, 2014
from the brownfields program. Failure to obtain approval may violate a brownfields agreement,
endangering liability protections and making said action subject to enforcement. Justifications
provided below must be approved by the Program in writing prior to completing transport activities.

☐ Use as Beneficial Fill Offsite – provide justification: Click here to enter text.
☐ Use as Beneficial Fill at another Suitable Brownfields Site – (Note: a determination that a
site is a “Suitable Brownfields” site will require, at a minimum, that similar concentrations of the same
or similar contaminants already exist at both sites, use of impacted soil as beneficial soil will not
increase the potential for risk to human health and the environment at that site, and that notarized
documentation of the acceptance of such soil from the property owner of the receiving site is
provided to Brownfields. Provide justification: Click here to enter text.
MANAGEMENT OF UTILITY TRENCHES
☐ Install liner between native impacted soils and base of utility trench before filling with clean fill
(Preferred)
☐ Last out, first in principle for impacted soils (if soil can safely be reused onsite and is not a
hazardous waste), i.e., impacted soils are placed back at approximately the depths they were
removed from such that impacted soil is not placed at a greater depth than the original depth from
which it was excavated.
☐ Evaluate whether necessary to install barriers in conduits to prevent soil vapor transport, and/or
degradation of conduit materials due to direct impact with contaminants? Result: Yes □ No □
If no, include rationale here. Click here to enter text.
If yes, provide specifications on barrier materials
Other comments regarding managing impacted soil in utility trenches: It is not anticipated that any

Modifier Description
<Indicates not detected at the reporting limit indicated.
“/”Separates the laboratory added data qualifiers from the validation data qualifiers. The
laboratory added data qualifiers precede the first “/”. The result qualifiers follow the first
“/”, and the analysis qualifiers follow the second “/”. The result qualifiers are a product of
the data validation process, and the analysis qualifier defines the type of QC excursion.
Laboratory Data Qualifiers
Qualifier Description
J Estimated concentration above the adjusted method detection limit and below the
adjusted reporting limit.
R2 The data used is from the diluted run due to the initial result exceeding the upper level of
calibration range.
Result Data Qualifiers
Qualifier Description
None
Analysis Data Qualifiers
Qualifier Description
A Percent difference between the primary and duplicate sample exceeded the established
criteria.

Contingency Plan
CONTINGENCY PLAN
IN THE EVENT UNKNOWN TANKS, DRUMS, OR OTHER WASTE MATERIALS ARE ENCOUNTERED
This contingency plan summarizes procedures to be followed in the event that unknown tanks, drums,
or other waste materials are discovered during the Parcel I Soil Remediation activities, which include
excavations in two previously characterized areas on Parcel I of the Former Scott Aviation Site located at
309 W. Crowell Street in Monroe, North Carolina.
In the event that a drum(s), tank(s), or other waste material is discovered during excavation activities,
the CONTRACTOR will immediately stop excavation activities, isolate the area, and notify the ENGINEER
(AECOM). The ENGINEER will be responsible for evaluating the potential health and safety and potential
environmental impact of the discovered material. Once the ENGINEER has determined a plan of action
for addressing the discovery, a Task Hazard Assessment (THA) will be conducted for that plan to identify
potential hazards and associated precautions to be taken to control the hazards. Any waste materials
removed from the Site will be characterized and disposed in accordance with applicable regulations.
In accordance with the accompanying Environmental Management Plan (EMP), NCDEQ will be notified
within 48 hours of the discovery.
