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 immediate 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. In the event unknown tanks, drums, other waste materials or previously unidentified impacted soils are encountered, Geoscience Group, Inc. shall characterize the the encountered items in geneal accordance with Il-ISB 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 inform 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: Contaminated soil scheduled for off-site disposal 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 disposal 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 disposal facility approved by Prospective Developer or their authorized representative.
