Green & Sustainable Remediation

  1. 1. INTRODUCTION TO GREEN AND SUSTAINABLE REMEDIATION (GSR) One-Hour Module Online Learning Copyright 2011
  2. 2. What’s in a Name? <ul><li>The term “Green Remediation” has evolved into “Green and Sustainable Remediation.” </li></ul><ul><li>This reflects ideas & practices that are effective in the short-term for cleanup, and offer long-term solutions to some of the carbon footprint and sustainability issues associated with cleanup itself. </li></ul>Photo source: Pixomar at
  3. 3. What is GSR (1)? <ul><li>Definitions (1) </li></ul><ul><ul><li>U.S. Environmental Protection Agency (EPA) “..Sustainability is considered in cleanups by establishing a preference for using strategies, practices and technologies that reduce the environmental footprint of Superfund and RCRA cleanups.” </li></ul></ul><ul><ul><li>Source: EPA. September 14, 2009. Greener Cleanups Policy – EPA Region 9. </li></ul></ul><ul><ul><li>California Department of Toxic Substances Control (DTSC) “ Green Remediation involves employing technologies and cleanup approaches to reduce a project’s environmental footprint.” </li></ul></ul><ul><ul><li>Source: DTSC. December 2009. Interim Advisory For Green Remediation. </li></ul></ul>
  4. 4. What are the Rules on GSR? <ul><li>There are NO REGULATIONS …yet. But that does not mean there are none being developed. </li></ul><ul><li>Federal Policies - 2011 </li></ul><ul><ul><li>All 10 EPA Regions have GSR policy statements. </li></ul></ul><ul><ul><li>Military installations and federal facilities apply GSR as part of the Sustainability requirements under Executive Order 13514 (Federal Register Vol. 74, No.194, Thursday October 8, 2009). </li></ul></ul>Photo source: Jeroen van Oostrom at
  5. 5. Are there Policies on GSR? <ul><li>State Policies </li></ul><ul><ul><li>Several states have policies in final or draft form that encourage GSR, e.g., California, Oregon and New York, but none have statewide regulations. </li></ul></ul><ul><ul><ul><li>California DTSC – Interim Advisory, December 2009 </li></ul></ul></ul><ul><ul><ul><li>Oregon DEQ – June 17, 2011 (Draft) </li></ul></ul></ul><ul><ul><ul><li>New York DEC – January 20, 2011 </li></ul></ul></ul><ul><ul><li>If remediation is State funded it may provide impetus for inclusion of sustainability in remedy review. </li></ul></ul>Photo source: Ohmega1982 at
  6. 6. No Rules – Why Consider GSR? <ul><li>Achieve remedial action goals </li></ul><ul><li>Support use and reuse of remediated parcels </li></ul><ul><li>Increase operational efficiencies </li></ul><ul><li>Reduce total pollutant and waste burdens on the environment </li></ul><ul><li>Minimize degradation or enhance ecology of the site and other affected areas </li></ul><ul><li>Reduce air emissions and greenhouse gas production </li></ul><ul><li>Minimize impacts to water quality and water cycles </li></ul>Source: Green Remediation: Incorporating Sustainable Environmental Practices into Remediation of Contaminated Sites .

  7. 7. Are there many Sites for GSR? <ul><li>Federal Facilities: </li></ul><ul><ul><li>Superfund Sites. By 2008, this program undertook > 9,400 removal actions </li></ul></ul><ul><ul><li>RCRA Sites. EPA estimated > 3,700 in 2008 </li></ul></ul><ul><ul><li>Underground Storage Tank Sites. Through September 2007 , 365,000 cleanups were completed, and ~109,000 sites were yet to be remediated </li></ul></ul><ul><ul><li>Department of Defense Sites ~ 8,000 </li></ul></ul><ul><ul><li>Department of Energy Sites ~ 4,000 contaminated or potentially contaminated areas </li></ul></ul><ul><li>S tate, Brownfield, and Private Sites: </li></ul><ul><ul><li>EPA estimates that during 2006 and 2007 cleanups were completed at over 18,900 sites </li></ul></ul><ul><ul><li>Source: Green Remediation: Incorporating Sustainable Environmental Practices into Remediation of Contaminated Sites .

  8. 8. A Few GSR Myths… <ul><li>It is an additional regulatory burden </li></ul><ul><li>It diverts resources from removing hazardous or harmful materials </li></ul><ul><li>It costs so much remediation is not feasible </li></ul><ul><li>It is too hard to define the benefits </li></ul><ul><li>It will force responsible parties to argue out of remediation </li></ul>Source: ASTSWMO. August, 2009 . Green Remediation: Getting Started by Debunking Some Myths. photostock at
  9. 9. Nuts & Bolts – What Can be Included as GSR? <ul><li>Clean diesel and idle-reduction strategies </li></ul><ul><li>Reduce number of trips and amount of transportation required </li></ul><ul><li>Use renewable energy where possible e.g., solar, wind, anaerobic digestion, geothermal </li></ul><ul><li>Use combined heat and power and energy efficient equipment </li></ul><ul><li>Use concrete where steel slag has been swapped out for carbon-intensive Portland cement </li></ul><ul><li>Use industrial byproducts rather than virgin materials </li></ul><ul><li>Recycle or reuse site materials from demolition </li></ul><ul><li>Minimize use of materials containing toxic substances </li></ul><ul><li>Reduce water use </li></ul>Photo source: Danilo Rizzuti at

  11. 11. Example of GSR - Aerojet-General Corporation, Rancho Cordova, CA 6-MW Farm The fully operational Aerojet solar farm encompasses more than 29,000 individual solar cells. Air Stripping Towers Since 1983, nine treatments plants have gone on line to treat ground water extracted from over 100 wells. This facility uses air stripping as well as ultraviolet/peroxide and biodegradation technologies to remove volatile organic compounds, NDMA, and perchlorate from ground water at a flow rate of 4,800 gallons per minute. Aerojet-General Corporation: Green Remediation Strategy: “ Capture solar energy in remote portions of the site to produce electricity that could offset air emissions associated with using utility-supplied electricity for extracting and treating more than 20 million gallons of ground water each day…”, accessed 7/25/11

Aerojet-General Corporation <ul><li>Sample of GSR Results </li></ul><ul><li>Avoiding an estimated 6,000 tons of carbon dioxide, 4 tons of sulfur dioxide, and 5 tons of nitrogen oxide emissions </li></ul><ul><li>Offsetting approximately 30% of the total electricity used by the groundwater extraction and remediation equipment </li></ul><ul><li>Began fully operating the expanded (6-MW) solar farm in June 2010 </li></ul>, accessed 7/25/11
  13. 13. Where is GSR Heading? <ul><li>Emerging technologies to increase cleanup efficiency and reduce GHG emissions e.g., terrestrial carbon sequestration </li></ul><ul><li>New Standards to be issued by ASTM – possibly by early to mid-2012 </li></ul><ul><li>Improved Risk Assessment </li></ul><ul><li>to inform the Risk </li></ul><ul><li>Management process </li></ul><ul><li>EPA Superfund Landfill Methane-to-Energy Pilot Project (December 2010). </li></ul>Jscreationzs at
