What is “Green Cleanup?”

ASTM E2893-13 Standard Guide for Greener Cleanups ”Greener cleanup” - the incorporation of practices,

processes, and technologies into cleanup activities with the goal of reducing impacts to the environment through reduced demands on natural resources and decreased emissions to the environment.

http://www.epa.gov/superfund/greenremediation/ http://www.clu-in.org/greenremediation/

Five Core Elements Minimize total energy use and maximize

renewable energy use Minimize air pollutants and greenhouse gas

emissions Minimize water use and impacts to water

resources Reduce, reuse, recycle materials and waste Customize remedy for future land use, and

protect ecosystems

What is “Sustainable?”

Executive Order 13423, January 26, 2007- Ҥ9(k)-"sustainable" means to create and

maintain conditions, under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic, and other requirements of present and future generations...”

Governing Regulations

Local, State, Federal Risk-Based Corrective Action Maximize protection of human health & the environment

• Identification of exposure pathways and receptors; • Prioritization of response required; • Incorporate risk analysis into the corrective action process; • Select appropriate corrective action measures

Chapter 62-780 FAC – “Global RBCA” Is it Green? Is it Sustainable?

Green Sustainable

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.

The GSR Decision Component

Pick “Green” Remedy Implementation

Could lead to a dead-end remedy: Ineffective, slow Require do-over work Miss corporate, regulatory, or technical

objectives

12

Corporate Preserve current land use Short term & long term goals? Control annual costs

Regulatory Protect human health and environment

Technical Control migration, reduce/eliminate

exposure potential Plume stability or meet residential criteria?
