“The practice of considering all environmental effects of remedy implementation and incorporating options 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 options to minimize the environmental footprint of cleanup actions.”

Why GSR?

Sustainable Remediation

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)
