At some point, citizens involved in watershed protection face the question - How do we pay for this? Most quickly realize that there are not enough grant funds to meet the needs for water quality projects. The Clean Water State Revolving Fund is a large, flexible, and largely untapped source of funding for watershed projects. It provides over $5 billion each year for traditional stormwater and wastewater projects, as well as over $200 million for nonpoint source projects, such as land conservation, agricultural best management practices, and clean-up of contaminated sites. Join us to hear more about how you can access the Clean Water State Revolving Fund to protect your watershed.

Many sites with chlorinated organic contamination in groundwater have gone through extensive remedial evaluations and actions. After years of operating high energy processes, their effectiveness has begun to diminish without remedial objectives being met. Other effective remedial alternatives can be applied; however, there are difficulties transitioning these sites from these high energy systems to other low energy remedial alternatives and eventually to Monitored Natural Attenuation (MNA). This training on the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition (the bridge) between aggressive remedial actions and MNA and vise versa. Enhanced attenuation (EA) is the application of technologies that minimize energy input and are sustainable in order to reduce contaminant loading and/or increase the attenuation capacity of a contaminated plume to progress sites towards established remedial objectives. Contaminant loading and attenuation capacity are fundamental to sound decisions for remediation of groundwater contamination. This training explains how a decision framework which, when followed, allows for a smooth transition between more aggressive remedial technologies to sustainable remedial alternatives and eventually to Monitored Natural Attenuation. This training will demonstrate how this decision framework allows regulators and practitioners to integrate Enhanced Attenuation into the remedial decision process. As our experience and knowledge grows around the implementation of MNA, the EA process will be considered an important management tool for optimizing site remedies and moving sites to final completion. This approach is consistent with the current regulatory environment and can be accommodated within a broad range of regulatory programs such as CERCLA and State dry cleaner regulations. This new framework and decision process will accelerate the environmental clean-up progress on a national scale and reduce overall costs, while still providing protection to human health and the environment. For reference during the training class, participants should download and print a copy of the decision flow chart, Figure 2-1 on page 10 of the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/eaco/ITRC-EACO-DecisionFlowchart.pdf.

Do you manage a Superfund landfill site? Is it producing methane gas? Have you wondered how to evaluate and responsibly manage the landfill methane gas? During this training we will discuss resources available to project managers to assess methane productivity at Superfund landfills as well as potential ways to use it as a source of energy or flare it, thereby reducing greenhouse gas emissions. EPA has a wealth of knowledge and experience with landfill gas that may have applicability to Superfund sites. This training will provide a brief overview of the tools available to evaluate, use and flare landfill methane gas and how they may apply to Superfund sites. Keep in mind that Superfund landfills are typically older, closed sites where codisposal of hazardous and municipal waste has occurred. The emissions will be different from a typical municipal landfill. Because of the age and types of waste, the volume of gas is likely less and concentration of hazardous air pollutants is likely higher. Therefore, before proceeding with exploring economics of energy recovery, the amount and characteristics of the landfill gas need to be evaluated. We will discuss how to conduct an evaluation using EPA's Guidance for Evaluating Landfill Gas Emissions From Closed or Abandoned Facilities (EPA-600/R-05/123a). We will also identify options for controlling emissions through either flaring the gas or recovery for its energy potential.
