Background

N/A

Requirements

  • Nelson Tunnel, the focus of the remedial action (RA), consists of an abandoned underground hard rock mine and drainage tunnel approximately 11,000 feet in length with several shafts, cross-cuts and drifts branching off the main tunnel. The remedial action objective of the RA is to reduce the likelihood of a large, uncontrolled release of mine-impacted water from mine pools impounded within the Nelson Tunnel. The selected alternative for the Nelson Tunnel interim Record of Decision (IROD) is to construct a bypass adit that connects into Nelson Tunnel at a sufficient distance from the surface to allow for installation of a flow-through hydraulic bulkhead within Nelson Tunnel. Preliminary planning is currently being performed to collect requisite information and better identify the requirements and details of this project.
  • Drive New Adit to Intersect Nelson Tunnel, Tunnel Rehabilitation, Install Bulkhead in Nelson Tunnel and Flow-Control Structure in Commodore 5 Level and includes the following remedial components:
    • Installation of a new adit south of Nelson Tunnel, to bypass the Nelson Tunnel Portal Pool
    • Rehabilitation of Nelson Tunnel from the bypass adit connection to the location where bulkhead construction is planned
    • Installation of a flow control bulkhead in Nelson Tunnel to protect against a sudden uncontrolled release through Nelson Tunnel.
    • Installation of an accessible bulkhead flow control structure in the Commodore 5 level to protect against a sudden uncontrolled release through this level.
