Green and Sustainable Remediation

 Definitions  U.S. Environmental Protection Agency  “The practice of considering all environmental

effects of remedy implementation and incorporating

ptions to maximize net environmental benefit of

cleanup actions.”

 Interstate Technology Regulatory Council (ITRC)  “The site-specific employment of products, processes,

technologies, and procedures that mitigate contaminant risk to receptors while making decisions that are cognizant of balancing community goals, economic impacts, and net environmental effects.

 New York State  “The practice of considering all environmental

effects of remedy implementation and incorporating

ptions to minimize the environmental footprint of

cleanup actions.”

Why GSR?

 Improved stakeholder engagement

 Community benefits  Educational opportunities  Collaboration

 Simplified, reproducible results

 Quantify desired metrics

 Reduced impacts

 Emissions / greenhouse gases  Energy/Water/Waste  Ecosystems

Sustainable Remediation

SLIDE 5

Brief History

 2006 – Sustainable Remediation Forum (SURF) formed; SURF formally

integrates sustainable principles, practices, and metrics into remediation projects and works to foster GSR on a national and international basis

 2007 – Association of State and Territorial Solid Waste Management

Officials (ASTSWMO) creates Green Cleanups Task Force which advocates for what are referred to as “greener cleanups”

 2008 – EPA develops The Green Remediation Technical Primer and forms the

EPA/State Greener Cleanup Working Groups

 2010 – NYSDEC issues DER-31 which establishes a preference for

remediating sites in the most sustainable manner while still meeting all legal, regulatory and program requirements

 2011 – Interstate Technology Regulatory Council (ITRC) publishes Green and

Sustainable Remediation Technology Overview (GSR-1) and GSR Technical/Regulatory Guidance (GSR-2)

 2013 – American Society of Testing and Materials (ASTM) publishes two

standard guides: Greener Cleanups (E2893), Integrating Sustainable Objectives into Cleanup (E2876), Best Management Table in Excel format

Evaluate BMPs to further reduce footprint



Power and Fuel

 Use biodiesel produced from waste or

cellulose-based products to power equipment

 Use on‐site generated renewable

energy to fully or partially provide power



Vehicle and Equipment

 Implement an idle reduction plan  Use biodegradable hydraulic fluids on

hydraulic equipment

 Use electric, hybrid, ethanol, or

compressed natural gas vehicles instead of conventional vehicles



Site Preparation and Land Restoration

 Reuse on-site or local clean materials

(e.g., crushed concrete)

 Use reclaimed asphalt pavement as a

granular base for new roads



Project Planning and Team Management

 Choose equipment and product

vendors with production and distribution centers near the site to minimize fuel consumption associated with delivery

 Select local waste disposal and

recycling facilities to minimize transportation impacts

 Use a local laboratory to minimize

transportation impacts

 Use local staff (including

subcontractors) when possible to minimize transportation impacts



Residual Solid and Liquid Waste

 Reuse or recycle recovered product

(such as resale of captured petroleum products, precipitated metals) and materials (for example, cardboard, plastics, asphalt, concrete)
