Whaler, i guess this Xstrata permit is standard procedure, but sure is a wake up call.
Xstrata Nickel, Sudbury Smelter Business Unit of Xstrata Canada Corporation has submitted a Mine Closure Plan for re-filing by MNDM as required under the Mining Act. This Closure Plan proposes rehabilitation measures to be implemented upon the eventual closure of Xstrata Canada Corporation’s Sudbury Smelter Area. The rehabilitation work to be conducted will include:

• Erosion protection
• Decommissioning roads and railroads
• Slope and revegetate slag piles
• Surface soil cleanup
• Interceptor well and treatment plant
• Fencing marginally stable crown pillar area
• Revegetation of smelter area
• Neutralizing, regrading and revegetation of Acid loadout area
• Demolishing buildings
• Flow monitoring and water management. Additional data will be collected from Emery and Coniston creeks.
