How Enforcement Actions can Support Reuse at Superfund Sites

EPA's enforcement program strives to balance our primary mission of ensuring that polluters pay for cleanups through an �enforcement first� strategy with strong support for EPA's contaminated site reuse goals. As such, the enforcement program helps facilitate site cleanup by pursuing responsible parties, but also recognizes that supporting reuse efforts can be a powerful incentive to encourage expeditious cleanups, save limited federal and state cleanup resources and help us all achieved our cleanup and enforcement goals to protect human health and the environment. This webinar will discuss the role of EPA's cleanup enforcement program in supporting the appropriate reuse of Superfund sites and will share case study examples of how enforcement tools, such as institutional controls, bona fide prospective purchaser (BFPP) criteria and continuing obligations, and negotiations to help address liability concerns, can help facilitate beneficial reuse at Superfund sites.

The Long-Term Impact of Metal Smelting Operations on Arsenic Availability in Urban Lakes of the South-Central Puget Sound Region

The ASARCO smelter in Ruston, Washington, contaminated the south-central Puget Sound region with heavy metals, including arsenic and lead. Arsenic and lead distribution in surface sediments of 26 lakes is significantly correlated with atmospheric model predictions of contaminant deposition spatially, with concentrations reaching 208 mg/kg As and 1375 mg/kg Pb. The temporal distribution of these metals in sediment cores is consistent with the years of operation of the ASARCO smelter. In several lakes arsenic and lead levels are highest at the surface, suggesting ongoing inputs or redistribution of contaminants. With 83% of the lakes in the deposition zone having surface sediments exceeding published "probable effects concentrations" for arsenic and lead, this study provides evidence for possible ongoing environmental health concerns. Moreover, this study finds that arsenic is highly mobile in these urban lakes, with maximum dissolved arsenic concentrations proportional to surface sediment levels and reaching almost 90 ppb As. Current knowledge of the chemical, physical and biological factors affecting arsenic mobility in these lakes will be discussed, and initial data on biotic effects explored.

Development of Performance Specifications for Solidification/Stabilization

Solidification/Stabilization (S/S) is a remedial technology option which blends treatment reagents into contaminated material to impart physical and/or chemical changes to reduce the flux of contamination that leaches from a contaminant source to within acceptable parameters set forth in a site-specific remediation goal. S/S can be effective for metals, asbestos, radioactive materials, oxidizers, PAHs, PCBs, and pesticides and is potentially effective for dioxins/furans, some VOCs and other organics. Although there is abundant literature describing the S/S process and test methods for design and implementation, there was a lack of guidance for assessing performance. The ITRC technical and regulatory guidance document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and associated Internet-based training provide an approach to assist practitioners and regulators with measuring and determining acceptable S/S performance. This approach developed by the ITRC Solidification/Stabilization Team provides information for developing, testing, and evaluating appropriate site-specific performance specifications and the considerations for designing appropriate long-term stewardship programs. In addition, the approach provides useful tools for establishing an appropriate degree of treatment and regulatory confidence in the performance data to support decision-making. This training and guidance is intended to be beneficial to anyone involved with CERCLA, RCRA, brownfields, UST or any other regulatory program where S/S has been selected or implemented as a remedial technology.

For reference during the training class, participants should have available a copy of the process diagram, Figure 4-1 on page 29 of the ITRC Technology and Regulatory Guidance Document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/ss/ITRC-SS-Process.pdf.

Biofuels: Release Prevention, Environmental Behavior, and Remediation

Biofuels and biofuel blends are a new category of transportation fuels and are defined as liquid fuels and blending components produced from renewable biomass feedstocks used as alternative or supplemental fuels for internal combustion engines. Their manufacture and consumption are increasing, in part, due to usage mandates and incentives both in the United States and abroad. This expanded use of biofuel and biofuel blends increases the potential frequency of releases due to increased manufacture, transportation, storage, and distribution. Because biofuels differ from conventional fuels with respect to their physical, chemical, and biological properties, their introduction poses challenges with respect to understanding the potential impacts of releases to the environment. Specifically, once released into the environment, these fuels will exhibit different environmental behaviors as compared to conventional fuels.

This training, which is based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011), focuses on the differences between biofuels and conventional fuels specific to release scenarios, environmental impacts, characterization, and remediation. The trainers will define the scope of the potential environmental challenges by introducing biofuel fundamentals, regulatory status, and future usage projections. Participants will learn how and when to use the ITRC biofuels guidance document for their projects. They will understand the differences in biofuel and petroleum behavior; become familiar with the biofuel supply chain, potential release scenarios and release prevention; be able to develop an appropriate conceptual model for the investigation and remediation of biofuels; and select appropriate investigation and remediation strategies.

Integrated DNAPL Site Strategy

Sites contaminated by chlorinated solvents present a daunting environmental challenge, especially at sites with dense nonaqueous phase liquid (DNAPL) still present. Restoring sites contaminated by chlorinated solvents to typical regulatory criteria (low parts-per-billion concentrations) within a generation (~20 years) has proven exceptionally difficult, although there have been successes. Site managers must recognize that complete restoration of many of these sites will require prolonged treatment and involve several remediation technologies. To make as much progress as possible requires a thorough understanding of the site, clear descriptions of achievable objectives, and use of more than one remedial technology. Making efficient progress will require an adaptive management approach, and may also require transitioning from one remedy to another as the optimum range of a technique is surpassed. Targeted monitoring should be used and re-evaluation should be done periodically.

This ITRC Integrated Dense Nonaqueous Phase Liquid Site Strategy (IDSS-1, 2011) technical and regulatory guidance document will assist site managers in development of an integrated site remedial strategy. This course highlights five important features of an IDSS including:

A conceptual site model (CSM) that is based on reliable characterization and an understanding of the subsurface conditions that control contaminant transport, reactivity, and distribution
Remedial objectives and performance metrics that are clear, concise, and measureable
Treatment technologies applied to optimize performance and take advantage of potential synergistic effects
Monitoring based on interim and final cleanup objectives, the selected treatment technology and approach, and remedial performance goals
Reevaluating the strategy repeatedly and even modifying the approach when objectives are not being met or when alternative methods offer similar or better outcomes at lower cost

This IDSS guidance and training is intended for regulators, remedial project managers, and remediation engineers responsible for sites contaminated by chlorinated solvents. Because the subject matter is complex, this guidance assumes a functional understanding of the field and is targeted towards experienced users; however, novices will benefit through descriptions and references of the latest evolution of site characterization challenges; realistic planning of site restoration; evolving treatment techniques; and evaluating, monitoring and interpreting mass transport in the subsurface aqueous and vapor phases. While the primary focus of the document is on DNAPL sites, other types of contaminated sites (e.g. petroleum, mixed contaminants, etc.) can use the same fundamental process described in this guidance.

For reference during the training class, participants should have a copy of the flow diagram, Figure 1-2 on page 6 of the ITRC Technical and Regulatory Guidance document, ITRC Integrated Dense Nonaqueous Phase Liquid Site Strategy (IDSS-1, 2011) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/IDSS/ITRC-IDSS-1-Figure1-2.pdf.

Green & Sustainable Remediation

The ultimate goal of remediation systems is to protect human health and the environment from contaminants. Historically, remedies have been implemented without consideration of green or sustainable concepts in order to meet this goal. This includes the potential for transferring impacts to other media. For instance, many remedial decisions do not assess greenhouse gas (GHG) emissions, energy usage, or community engagement factors prior to the investigation or remedy implementation. Considering these factors throughout the investigation and remedy implementation process may lessen negative effects of the overall cleanup impact while the remediation remains protective of human health and the environment. The consideration of these factors is Green and Sustainable Remediation (GSR) - 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.

Many state and federal agencies are just beginning to assess and apply green and sustainable remediation into their regulatory programs. This training provides background on GSR concepts, a scalable and flexible framework and metrics, tools and resources to conduct GSR evaluations on remedial projects. The training is based on the ITRC's Technical & Regulatory Guidance Document: Green and Sustainable Remediation: A Practical Framework (GSR-2, 2011) as well as ITRC's Overview Document, Green and Sustainable Remediation: State of the Science and Practice (GSR-1, 2011).

Beyond basic GSR principles and definitions, participants will learn the potential benefits of incorporating GSR into their projects; when and how to incorporate GSR within a project's life cycle; and how to perform a GSR evaluation using appropriate tools. In addition, a variety of case studies will demonstrate the application of GSR and the results. The training course provides an important primer for both organizations initiating GSR programs as well as those organizations seeking to incorporate GSR considerations into existing regulatory guidance.
