ROSEMONT COPPER - A BRIDGE TO A SUSTAINABLE FUTURE 13 Waste Management TITLE: Non-Municipal Solid Waste Landfill Application RELEASE DATE: August 2010 PREPARED BY: Civil & Environmental Consultants, Inc. Brief Summary: A landfill to be constructed at the Rosemont Copper site will function without any structural failures that could cause a discharge to the underlying aquifer. The potential for landfill impacts on groundwater is considered to be negligible, according to this Civil & Engineering Consultants, Inc. report. These are some of the factors underlying the conclusions: • A hydraulic capture zone will be created in the aquifer as a result of dewatering of the pit. It will extend out beyond the boundaries of the landfill and will exist during operations and persist for at least 100 years after mine closure. • The Willow Canyon Formation under the landfill is several thousand feet thick and will yield little to no water seepage to wells. • Physical features in the area and the 24-inch soil liner to be installed indicate that any potential releases from the landfill will not migrate to groundwater. • No materials that produce hazardous wastes will be placed in the landfill. When the landfill is closed, it will be covered by a minimum of 1.5 feet of soil overlain by six inches of topsoil that will be appropriately re-vegetated. Post-closure objectives for the landfill will conform to typical rural value associated with Western open space. Those uses will include dispersed recreation, wildlife habitat and ranching.

TITLE: Non-Municipal Solid Waste Landfill ApplicationRELEASE DATE: August 2010PREPARED BY: Civil & Environmental Consultants, Inc.Brief Summary: A landfill to be constructed at the Rosemont
Copper site will function without any structural failures that could cause a discharge to the underlying aquifer. The potential for landfill impacts on groundwater is considered to be negligible, according to this Civil & Engineering Consultants, Inc. report.
These are some of the factors underlying the conclusions:•A hydraulic capture zone will be created in the aquifer
as a result of dewatering of the pit. It will extend out beyond the boundaries of the landfill and will exist during operations and persist for at least 100 years after mine closure.
•The Willow Canyon Formation under the landfill is several thousand feet thick and will yield little to no water seepage to wells.
•Physical features in the area and the 24-inch soil liner to be installed indicate that any potential releases from the landfill will not migrate to groundwater.
•No materials that produce hazardous wastes will be placed in the landfill.
When the landfill is closed, it will be covered by a minimum of 1.5 feet of soil overlain by six inches of topsoil that will be appropriately re-vegetated.
Post-closure objectives for the landfill will conform to typical rural value associated with Western open space. Those uses will include dispersed recreation, wildlife habitat and ranching.
The waste management study looked at potential landfill impacts to groundwater and Rosemont project land .
