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…” http://www.clu-in.org/greenremediation/subtab_d31.cfm, accessed 7/25/11

Editor's Notes
Welcome and thank you for choosing the online module “An Introduction to Green and Sustainable Remediation” In this course we will: 1. Define Green & Sustainable Remediation – which we will refer to as GSR 2. Review some of the regulations and policies governing GSR regionally and nationally 3. Look at the nuts and bolts of implementing GSR 4. Examine three case studies as examples of successful GSR projects 5. Project the likely future of GSR and 6. Offer you some useful links to online GSR resources The course is designed to take one hour to complete and includes 3 short quizzes.
The EPA Region 9 Greener Cleanups Policy establishes a preference for use of a range of practices, strategies and technologies to support the implementation of greener cleanups. These and other strategies are discussed throughout this module along with the tools and techniques that can be used to………….
OR DEQ = Dept of Env. Quality. “DEQ’s Cleanup Program will promote, support and implement more sustainable practices that lessen the overall environmental impacts of investigation and remediation projects.” NY DEC = Dept of Env. Conservation. “DEC is dedicated to developing and promoting innovative cleanup strategies that restore contaminated sites to productive use, promote environmental stewardship, and reduce associated costs while minimizing ancillary environmental impacts from these cleanups.” CA DTSC = Dept of Toxic Substances Control. “The advisory introduces the concepts of sustainability and life-cycle thinking and shows how these concepts can be incorporated into any stage of a cleanup project, …. This advisory also presents a simple tool, the green remediation evaluation matrix (GREM).
To answer this question – Why Consider GSR – we have to understand the principles of Green and Sustainable Remediation. Part of the EPA Mission is to protect human health and the environment. By promoting sustainable strategies in the removal of health threats from the environment, it provides added benefits through the use of sustainable cleanup actions. States are also promoting GSR for the same reasons – protection of public health and the environment for the long term. Other examples not listed here include: Conserve natural resources Achieve greater long-term financial return from investments Increase sustainability of site cleanups
There are 10’s of thousands of sites that have been or are undergoing remediation, and thousands more that will be ready for remediation over the coming decades. Federal facilities alone constitute over half a million locations nationwide through 2008. The cleanup strategies needed will almost certainly include consideration of the GSR principles for a combination of environmental protection, and increasingly for cost savings and energy efficiency reasons.
There is no legislation so GSR has evolved from a voluntary approach to achieve the overall goal of protection of public health and the environment. It begins with innovative project managers interacting with agency staff to find the most reasonable approaches. Change perspective from just removal of one source of hazard to elimination of as many sources as possible. Not just moving contamination from soil or GW to air, or on-site to off-site. Inclusive rather than exclusive. Not necessarily. There may be some increased efficiencies that result in an overall net cost benefit. Look long-term, not just short-term. Start with the simple ideas first, like low sulfur-diesel fuels, and use tools for decision making that include sustainable solutions. (See some on the EPA slide that follows later). Not allowed. Just because GSR is a good practice does not make it a lever for arguing out of all forms of remediation.
Here are a few examples of publicly available tools for evaluating the “footprint” of site remediation. Each of the sponsors is listed after the specific tool. Government, industrial, academic and non-profit organizations offer many Web-based calculators, software models, and supplemental materials. These may be free or commercially available. Most tools address more than one of the core elements of GSR ( discussed 4 slides previous ).
