7. Abandonment of Wells.
7.1 If Subcontractor fails to complete a monitoring well as specified, or abandons a monitoring well because of loss or failure of tools or equipment, or other causes not related to unexpected natural causes or differing site conditions (as discussed below), Subcontractor, if requested by ERM, shall fill the abandoned well with a cement bentonite slurry according to applicable agency specifications and salvage and remove such casing as can be salvaged. All salvaged casing or materials furnished by Subcontractor will remain Subcontractor’s property. The cost of abandonment of the monitoring well, including the filling, shall be borne solely by Subcontractor and no allowance or payment shall be made for the drilling, casing or other work performed by Subcontractor on the abandoned monitoring well.
7.2 If a monitoring well must be abandoned due to a natural cause, deemed to be a geologic formation comprised of a type of material that could not have been anticipated, such as heaving sands or large boulders, and could not be drilled using Subcontractor's existing equipment, or subsurface or latent conditions at the Project Site differing materially from the conditions indicated in this Subcontract and the Prime Contract or the existence of a previously unknown condition at the Project Site of an unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in work of the nature provided for in the Work Authorization (hereinafter referred to as "differing site condition"), and neither ERM nor Subcontractor were aware of such conditions, Subcontractor shall, in writing and within 5 days from when the well is abandoned by Subcontractor, notify ERM of the existence of the natural cause and/or differing site condition and shall specify the costs incurred by Subcontractor as a result thereof.
7.3 ERM shall, within ten (10) days of receiving such written notice from Subcontractor, notify Client of the natural cause and or the differing site condition and the costs incurred by Subcontractor and ERM, if any, as a result thereof, and shall request compensation from Client for such costs. If Client determines that there is entitlement to some or all of the requested costs, ERM’s reasonable determination as to Subcontractor’s share of any equitable adjustment issued by Client shall be final, binding and conclusive on Subcontractor. If Client determines that there is no entitlement to additional costs, Client’s decision shall be final, binding and conclusive on Subcontractor. Subcontractor’s failure to comply with the notice requirements herein shall constitute a waiver of its right to submit a claim for additional costs hereunder.
8. Decontamination of Equipment. At Subcontractor’s sole cost and expense, all drilling, geotechnical or excavation equipment must be thoroughly steam cleaned by Subcontractor before entering the Project Site, after completing each boring, well, excavation or trenches and at other appropriate times specified by ERM field personnel. All down-hole equipment must be thoroughly decontaminated prior to arrival on site. In addition, due to the potential presence of chemical contaminants in boreholes, excavations, trenches and/or wells to be evaluated by Subcontractor, all equipment, including without limitation down-hole equipment must be thoroughly decontaminated by Subcontractor between boreholes, excavations, trenches and wells, and Subcontractor will provide suitable cleaning mechanisms to decontaminate its equipment. All such equipment must be thoroughly decontaminated by Subcontractor prior to leaving the Project Site. In lieu of decontamination activities, ERM reserves the right to replace, at ERM’s cost, the contaminated equipment component(s).
9. Lost or Lodged Equipment. Under no circumstances will ERM be responsible for any additional cost resulting from the loss of equipment nor will it be expected to compensate Subcontractor for the loss of any equipment.
10. Transportation and Disposal of Waste.
10.1 Subcontractor is responsible, at its sole cost and expense, for transporting, treating and/or disposing of all of the drill cuttings, drilling fluids and water that comes in contact with or is extracted or purged from the subsurface formation, and excavated soil, rock and other material requiring off-site disposal pursuant to Section 5.2 above (the “Waste”) in accordance with all Laws, including with limitation Environmental Laws.
10.2 Subcontractor represents and warrants that it will accept legal title and sole responsibility for the Waste upon its generation by the Subcontractor.
