NARPM Presents...RECs, Renewables and Remediation

This introductory level session provides an overview of the spectrum of options available to reduce, or at least offset, the energy footprint of your sites. We explain what renewable energy credits (REC) really are, provide information about generating small-scale renewable energy on-site using mobile systems and cover the basics of how to evaluate the feasibility of using on-site renewable energy to power a remedy. The session includes a presentation on a Screening-Level Renewable Energy Assessment that was conducted for a site in the EPA Region 3, which systematically evaluated the existing energy infrastructure available for the site and options for onsite electricity generation via wind, solar, biomass, geothermal and hydropower. Our goal is that participants leave the session with sufficient information to feel comfortable evaluating and selecting greener energy strategies for their sites. This course should be suitable for all RPMs.

Wastewater Treatment and Related Modeling Technical Workshop

On April 18, 2013, EPA hosted a Hydraulic Fracturing Study Technical Workshop on Wastewater Treatment and Related Modeling. This one-hour webinar will provide a summary of the workshop and cover workshop themes, including hydraulic fracturing wastewater treatment, and current and future trends in hydraulic fracturing wastewater management.

EPA's Methodology for Understanding and Reducing a Project's Environmental Footprint

The process of cleaning up a hazardous waste site uses energy, water and other natural or materials resources and consequently creates an environmental footprint of its own. In February 2012, the U.S. EPA released a methodology for quantifying the environmental footprints. The information obtained helps prioritize efforts to reduce the footprint and improve the outcome of cleanups under any regulatory program. This two-hour seminar will: (1) briefly discuss the regulatory framework; (2) summarize the methodology for estimating or quantifying the footprint and the associated metrics; (3) walk participants through the steps of performing an environmental footprint analysis; (4) present some questions for discussion and share lessons learned from early adopters. An open forum will be held after the presentations, during which participants will be able to submit questions and feedback to the speakers.

Environmental Molecular Diagnostics: New Tools for Better Decisions

Interstate Technology Regulatory Council Environmental molecular diagnostics (EMDs) are a group of advanced and emerging analytical techniques used to analyze biological and chemical characteristics of environmental samples. Conventional data (e.g., hydrogeological data, chemical, and geochemical analyses) often provide only indirect data regarding the mechanisms and rates of key attenuation or treatment processes. EMDs can complement these data by providing direct measurements of the organisms, genes or enzymes involved in contaminant biodegradation, of the relative contributions of abiotic and biotic processes, and of the relative rates of various degradation processes. The information provided by EMDs can improve estimates of attenuation rates and capacities and improve remedy performance assessments and optimization efforts. Improved understanding of the biological and non-biological degradation processes also can lead to greater confidence in MNA or closure decisions. EMDs have application in each phase of environmental site management (including site characterization, remediation, monitoring, and closure activities), address a wide variety of contaminants (including PCE, PCBs, radionuclides, perchlorate, fuels), and work with various media (including groundwater, soil, sediments, soil vapor).

Although EMDs have been used over the past 25 years in various scientific fields, particularly medical research and diagnostic fields, their application to environmental remediation management is relatively new and rapidly developing. The ITRC Environmental Molecular Diagnostics Fact Sheets (EMD-1, 2011), ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013) and this companion Internet-based training will foster the appropriate uses of EMDs and help regulators, consultants, site owners, and other stakeholders to better understand a site and to make decisions based on the results of EMD analyses. At the conclusion of the training, learners will be able to determine when and how to use the ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013); define when EMDs can cost-effectively augment traditional remediation data sets; and describe the utility of various types of EMDs during remediation activities.

Training participants are encouraged to review the ITRC EMD Fact Sheets, in particular the Introduction to EMDs fact sheet, before the Internet-based training.

Development of Performance Specifications for Solidification/Stabilization

Interstate Technology Regulatory Council 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

Interstate Technology Regulatory Council 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.
