AIR FORCE POLICY
Refocusing the Environmental Restoration Refocusing the Environmental Restoration Program• December 2010 Policy Memoy
─ Focus on broadest site closure possible (fence-to-fence)─ Directed use of PBC contracts
Life cycle costs must be evaluated to select alternatives other ─ Life-cycle costs must be evaluated to select alternatives other than site closure
─ Focus on site closure instead of remedy efficiencyPBC t t t l ith i ti t d ─ PBC contracts must comply with existing agreements and regulations
─ Site closure is defined as no additional time or dollars
