Contingency For Encountering Unknown Tanks, Drums,
Or Other Waste Materials
Contingency For Encountering Unknown Tanks, Drums, Or Other Waste
Materials
Previously Unidentified or Unforeseen Conditions: Previously unidentified or unforeseen conditions are
defined to mean the discovery of potentially regulated (i.e., by NCDEQ) soil or groundwater that
presents, through normal and routine field observations, field detection instruments or laboratory
analyses, characteristics different from other non-affected media in the area being worked. These
characteristics are typically expected to be triggered by visual and/or odor indications. If previously
unidentified or unforeseen conditions are encountered during site development, it is each worker's
obligation to report such conditions to their inunediate supervisor who will, in-turn, notify the Prospective
Developer. The protocol presented herein will then be implemented as applicable and appropriate, to
manage the proper resolution of unidentified or unforeseen conditions.
Work by each site contractor and site sub-contractor must be accomplished within the framework of an
appropriate Site-Specific Health and Safety Plan (HASP). Level D Personal Protect Equipment (PPE),
which includes hard-hats, steel-toed safety boots, safety glasses with side-shields and high-visibility
safety vests, is the minimum level of PPE to be used for all site work. All truck drivers who exit their
trucks on-site will be subject to the health and safety requirements established for the Site. Geoscience
will make available to contractors and subcontractors, upon request from the contractors and sub-
contractors for provision, the due diligence data so that informed and responsible decisions can be made
by those contractors and subcontractors regarding the health and safety of their employees.
Each contractor and sub-contractor is specifically and wholly responsible for the safety of their workers,
including any PPE and training, as may be warranted or required by law and regulations. Prospective
Developer and Geoscience Group, Inc., are responsible only for the safety of their respective employees.
Suspected Asbestos Containing Materials:
Any buried debris encountered during construction should be considered suspect asbestos containing
material.
• Upon discovery, immediately stop construction activities and report the condition to
Geoscience Group, Inc.
• For as long as the suspected asbestos remains exposed, control access to the site to prevent entry
by unauthorized and/or unprotected persons. During the entire time the suspected asbestos
remains exposed, the exposed area must be either wetted or covered to prevent the spread of
asbestos fibers. An asbestos disposal site which remains uncovered must remain wetted, and be
fenced and posted with warning signs, unless a natural barrier adequately deters access.
• Assure that there are no visible emissions from the uncovered site, as required by federal
regulations. An effective means for doing so is to keep the exposed material moist, by using a
fine spray or mist.
• Take care not to walk through, drive through, touch, or otherwise make direct contact with the
suspected asbestos-containing material. Keep pets and children away from the area. Be aware
that making direct contact with the asbestos may result in contaminating clothes and skin, which
in turn may result in asbestos fibers becoming airborne or ingested.
• Geoscience shall arrange for a qualified professional to be on-call to determine whether the
encountered debris contains asbestos. If the material tests positive for asbestos, Geoscience shall
develop a plan for covering or removing the asbestos-containing material.
• Implement the plan, after consulting with Geoscience and the North Carolina Brownfields
Program to assure that the work is protective of human health and complies with Mecklenburg
County and State disposal requirements and/or other applicable regulatory requirements. Note:
this type of work must be carried out by a professional who is properly equipped and trained.
Lacking proper equipment and training, a person engaging in this type of work is at risk of
personal exposure, causing other human exposures, and violating local, state, and/or federal
regulation.
• Always seek the advice and assistance of Geoscience and the North Carolina Brownfields
Program whenever there is any question about imminent hazard response actions, and/or the
ability to carry out any activity without causing a release of asbestos fibers.
Unknown Tanks, Drums, Other Waste Materials or Previously Unidentified Impacted Soils:
In the event unknown tanks, drums, other waste materials or previously unidentified impacted soils are
encountered that do not test positive for asbestos, Geoscience Group, Inc. shall characterize the
encountered items in general accordance with IHSB protocol. The extent of suspected impacted soils
encountered during construction, or other excavation activities, will be determined through field
observation. Screening of the excavated suspect soils using a PID will also be performed as appropriate.
Suspect soils will be stockpiled on-site pending the results of characterization testing. In general
accordance with typical stockpile sampling protocols, such as those provided in NCDENR Division of
Waste Management's Guidelines for Sampling, composite samples (consisting of six sub-samples) will be
collected at a frequency of approximately one sample per 200 cubic yards of stockpiled suspect soil. The
characterization samples will be submitted for analysis consistent with perceived contaminants
encountered at the site.
Excavation of known or suspected impacted soil shall follow these procedures:
• It is not anticipated that soil handling will require a work stoppage or an upgrade from Level D
PPE to Level C. However, in the event of the discovery of a previously unknown area of potential
soil contamination, the Site Environmental Representative will be responsible for evaluating
whether a work stoppage or a PPE upgrade is appropriate. In the event of work stoppage, the Site
Environmental Representative will infonn the NCBP Representative and the Prospective
Developer.
• The number of samples to be collected from the excavated soil will depend upon the quantity of
soil generated and the specific conditions at hand.
• Excavated areas will be managed as practicably as possible to prevent accumulation of rainwater.
Whenever possible, excavation of suspect contaminated soil will be performed when prevailing
and incipient weather conditions are favorable. Plastic sheeting and temporary backfilling with
non-contaminated soil may be used to reduce/preclude the accumulation of storm water in the
excavated areas.
• The potentially-affected area will be clearly marked. Safety precautions will be adjusted, as
appropriate, based on the circumstances. For instance, high visibility snow fencing, safety cones,
temporary signage and/or temporary hard-fencing may be used as needed to best suit the specific
condition at-hand.
• Areas used for soil staging will be clearly marked both in the field and on sketch outlines.
• Stockpiling of soil for several days prior to loading may be performed, pending receipt of
laboratory analysis results.
• Stockpiled potentially impacted soil will be stored on a liner and will be covered with secured
plastic sheeting while not being worked and at the end of each day. Appropriate erosion and
sediment controls, such as hay bales and/or silt fencing, will also be implemented to prevent
runoff from this soil.
Transport and Disposal of Contaminated Soil (Non-Asbestos): Contaminated soil scheduled for off-site
disposal at an appropriate landfill facility will be properly characterized for disposal, manifested,
transported and disposed of in compliance with applicable laws. A record of each truck dispatched from
the Site for off-site disposal will be paired with the associated manifest and weight ticket report received
from the landfill facility. Based on previous environmental assessment activities conducted at Site, off-
site disposal of soil, if required, is expected to be characterized as non-hazardous solid waste.
• Truck loads will be covered prior to leaving the Site.
• During bulk transport of non-hazardous soils, applicable marking requirements will be used to
display the appropriate DOT placards.
• Proper Class 9 placards will be used if hazardous soil/material is being transported off-site for
disposal, although this is not anticipated.
• Proper documentation required for the shipment of contaminated waste off-site will be managed
in the field. A record of each truck dispatched from the Site for off-site disposal will be paired
with the associated manifest and weight ticket report received from the landfill or disposal
facility.
• Soil will be disposed of in accordance with applicable state and local regulations at an appropriate
landfill facility approved by Prospective Developer or their authorized representative. Prior
approval from DEQ must be obtained for any proposed disposal location that is not a landfill
properly licensed to receive the material.
