  • 1. 2011Sustainability &Green Remediation Christie Sunderrajan, P.E., CHMM 1
  • 2. 2011Definitions • Green Remediation - The practice of considering all environmental effects of remedy implementation and incorporating options to minimize the environmental footprints of cleanup actions. • Sustainable development - development that meets the needs of the present without compromising the ability of future generations to meet their own needs. • WCED "Our Common Future" (The Brundtland Report, 1987) 2
  • 3. 2011Superfund Green Remediation Strategy 3
  • 4. 2011 Policy / Guidance DevelopmentKey Action #1: Clarify the role of green remediation in remedy selection and implementation • Integrating GR within current program • Policy – Consistent GR approach – Superfund Program (UD) • Evaluate ARARs – Potential existing State / Fed regulations / Policies (UD) (UD) – Under Development (TBI) – To Be Initiated 4
