	~~The final EE/CA Alternative 2 is the recommended alternative. This alternative involves placing the~~
	~~tailings from the piles and ponds into an on-site repository near the tailings deposits. This represents a minor~~
	~~design change from the Draft Final EE/CA which conceptualized two repositories. Additional analyses~~
	~~demonstrated that a single repository is less expensive and reduces operation and maintenance~~
	~~requirements. The repository will be sited to keep the consolidated tailings out of the 500-year flood plain.~~
	~~The tailings that are contained near drainage courses will be relocated to reduce the potential for these~~
	~~tailings to be washed downstream during flood events. In addition, the channel will be restored and sized for~~
	~~the 500-year flood event, and run-on controls will be established around the repository. This alternative best~~
	~~met the screening criteria as most effective, implementable and cost-effective.~~
