    the cleanup.

  • Attend meetings with DFG staff, contractors, and regulatory agencies, providing geologic expertise and recommendations to aid DFG in decision making.

  • Attend public meetings with DFG staff, and be on call to discuss technical issues relating to mine closure.

  • Review periodic technical reports and documents prepared by the closure contractor to ensure all regulatory issues are met.

  • Conduct on-site field engineering geology of the closure work, including change of order, reporting, review of plans and design of stream restoration.

  • Provide other technical consultations to DFG on mine closure issues as required.
