70CNR-S3893 Scope of Work Mine Site Interim Fluid Management

SCOPE OF WORK

Services provided under this contract shall address the emergency management of mine impacted process water in the scenario where an operator defaults on an actively permitted mine site.

Due to the broad nature of services that may be required under this contract, a specific scope of work with well-defined tasks, objectives, activities, and deliverables cannot be provided, Instead, services will be on an “as needed” basis, at the discretion and direction of the Division.

The particulars of required services shall be dependent upon the site conditions of the mine.

The following capabilities are anticipated to be required under the contract: however, this is not to be considered a comprehensive description of all required services.

MINE SITE AND INTERIM PROCESS FLUID MANAGEMENT SERVICES

The purpose of this site-specific service is to enable the Division, through its contractor, to manage mine impacted process water in the scenario where an operator defaults on an actively permitted mine site.

Direction from the Division will require specific process fluid management actions to maintain containment and disposal of process fluid drain down volume from:

Heap leach pad(s) Tailings impoundment(s) Collection pond(s) Waste rock dump(s) Any other mine features that can potentially degrade waters of the State

The following associated actions apply:

The contractor will be required to pump and recirculate process solution(s) from the existing collection pond(s) onto the top of the heap leach pad and/or tailings process facility to prevent the process solution collection pond(s) from overflowing containment and to achieve zero discharge to the environment.

The contractor will be required to perform active evaporation of the process solution to initiate reduction of the solution volume. The evaporation equipment will be located on top of the mine facility’s containment area and/or the collection pond(s) lined containment area.

The contractor will be required to operate and maintain process solution management equipment for both the pump back re-circulation system and the evaporation operational system at relatively the same time for the most effective outcome.

The contractor will be responsible for designing a plan to ensure performance of all solution management equipment to achieve the requirements as noted above for an estimated 6-month interim fluid management period.

Additional Mine Site Services that may be performed as part of the awarded contract include, but are not limited to:

Process pond and heap conveyance channel liner repairs Inspecting, repairing, and operating on-site heap pump back equipment to include electrical service connections, generator(s), fuel storage tank(s), pumps, piping, sprinklers/misters/drippers and any other onsite heap pump back system equipment Renting/leasing/purchasing of pumps, piping, generators, fuel storage tank(s), fuel, electricity, sprinklers/misters/drippers, and any other material items not available on site necessary for successful heap pump back operations or land application activities Heap detoxification activities Site security to include fencing installation and/or repair, securing site access and maintaining an on-site presence Document searches and reviews, and preparation of monitoring data and reports Process solution/surface water/groundwater sampling and transport under chain of custody Well/piezometer/lysimeter installation and monitoring Soil/heap borings and sampling Tailings impoundments and/or waste rock dump geophysical and geochemical stability assessments and monitoring Provide detailed cost estimates for various scenarios and solutions Mathematical modeling of heap covers and contamination fate and transport through the vadose zone Coordination of work activities with State, Federal, and local agencies, and private land holders Development and implementation of HASPs, SAPs, and QAPPs Manage sub-contractors as needed or requested by NDEP, and provide all sub-contractor reports Remedial action construction oversight Human Health and/or Ecological Risk assessments Data interpretation, report preparation, and recommendations for further work Hazardous waste characterization and coordination of manifesting, treatment and disposal requirements Construction/engineering design and specifications (in Construction Specification Institute (CSI) format and in Imperial (English) units Process pond sump pumping Leak detection port monitoring and pumping Designing passive or active process solution treatment systems Pit lake monitoring and treatment (modeling not required) Provide data collection needs and methods of analysis (i.e. ASTM, EPA) Development of schedule of activities (i.e. Gantt charts).
