ITRC LNAPL Training Parts 1, 2, and 3 - May 4, 11, 18. Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum hydrocarbon products that are immiscible with water and less dense than water. LNAPLs are important because they are present in the subsurface at thousands of remediation sites across the country, and are frequently the focus of assessment and remediation efforts. Part 1 of this training course explains how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1 also explains what LNAPL data can tell you about the LNAPL and site conditions. Relevant and practical examples are used to illustrate key concepts. Part 2 addresses LNAPL characterization and site conceptual model development as well as LNAPL recovery evaluation and remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when and why those data may be important, and how to get those data. Part 2 also discusses how to evaluate LNAPL recoverability. Part 3 uses the LNAPL conceptual site model (LCSM) approach to identify the LNAPL concerns or risks and set proper LNAPL remedial objectives and technology-specific remediation goals and performance metrics. Part 3 also provides an overview of the LNAPL remedial technology selection framework. For more information and to register, see or

Filing EPA Information in AES Targeted at Current Exporters Only - May 8 & June 5. Exporters of manifested hazardous wastes, spent/used lead-acid batteries, universal wastes and cathode ray tubes for recycling should now be transitioning to an electronic border process using the Automated Export System (AES) or AESDirect. This 30-minute webinar will provide detailed filing instructions for exporters and their authorized filing agents (e.g., customs brokers) on how to file the RCRA information about their shipments in AES and AESDirect.

ITRC Long-term Contaminant Management Using Institutional Controls - May 9, 2017, 1:00PM-3:15PM EDT (17:00-19:15 GMT). ITRC's Long-term Contaminant Management Using Institutional Controls (IC-1, 2016) guidance and this associated training class focuses on post-implementation IC management, including monitoring, evaluation, stakeholder communications, enforcement, and termination. The ITRC guidance and training will assist those who are responsible for the management and stewardship of Ics. ITRC has developed a downloadable tool that steps users through the process of planning and designing IC management needs. This tool can help to create a long lasting record of the site that includes the regulatory authority, details of the IC, the responsibilities of all parties, a schedule for monitoring the performance of the IC, and more. The tool generates an editable Long Term Stewardship (LTS) plan in Microsoft Word. After attending the training, participants will be able to: describe best practices and evolving trends for IC management at individual sites and across state agency programs; use this guidance to improve IC reliability and prevent IC failures, improve existing, or develop new, IC Management programs, and identify the pros and cons about differing IC management approaches; use the tools to establish an LTS plan for specific sites; and use the elements in the tools to understand the information that should populate an IC registry or data management system.

Superfund Redevelopment Initiative Series: Restoring Superfund Sites to Public Good - May 15, 2017, 2:00PM-3:30PM EDT (18:00-19:30 GMT). Superfund sites can be reused in many ways, but many local governments are seeing unique opportunities to use sites for public or local government purposes. From roads to firefighting training facilities, local governments who own or acquire Superfund sites are finding ways to put these properties to good use. For more information and to register, see

SERDP & ESTCP Webinar Series - May 18, 2017, 12:00PM EDT (16:00 GMT).

OSC Academy Presents…ESA and NHPA for OSCs and RPMs - May 23, 2017, 1:00PM-3:00PM EDT (17:00-19:00 GMT). The course provides OSCs and RPMs with an overview of the Endangered Species Act (ESA) and Section 7 requirements under EPA's Emergency Response and Removal Program, including a discussion of the responsibility to consider the effects of its actions on listed species and their habitat and the components of Section 7 consultation. The course also provides OSCs and RPMs with an overview of the National Historic Preservation Act (NHPA) and Section 106 requirements under EPA's Emergency Response and Removal Program, including a discussion of its responsibility to consider the effects of its undertakings on historic properties and the components of Section 106 review. The primary audience for this training is EPA OSCs and RPMs; however, it is open to other federal agencies, states, tribes and consultants who are interested in learning more about the ESA and NHPA statutes.

Overview, Lessons Learned and Best Practices Derived from Independent Optimization Reviews of Superfund Mining Sites - May 24, 2017, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This webinar presents an overview of the EPA Office of Superfund Remediation and Technology Innovation (OSRTI) "Mine Site Optimization Initiative," and summarizes the lessons learned identified and best practices derived from independent optimization reviews performed on over 30 Superfund mine sites and mining district sites nationwide. The initiative is being performed under the EPA's National Strategy to Expand Superfund Optimization Practices from Site Assessment to Site Completion, which expanded and formalized optimization practices as an operating business model for the Superfund remedial program. The webinar will present case studies of mine site reviews performed, a summary of specific lessons learned identified for site characterization, and an update on the development of best practices resources to support consistent and safe approaches to characterization of mine sites with the potential for sudden, uncontrolled release of mining-influenced waters.

Research Update: Assessing Sediment Cap Effectiveness at the McCormick and Baxter Superfund Site. The McCormick and Baxter Superfund Site is located on the Willamette River in Portland, Oregon and has PAH contaminated soils and sediments from historical creosote operations. As part of an Oregon Department of Environmental Quality (ODEQ) ten year study to assess the effectiveness of the sediment cap, passive sampling devices were deployed by U.S. EPA Region 10 divers in both sediment and water at the site. Included in this study was a newly designed passive sampling sediment probe which allowed for deployment in the rocky armoring of the sediment cap. Based on data from this study, the ODEQ reported that the sediment cap appears to be effective in meeting its remedial objectives.

Groundwater High-Resolution Site Characterization (HRSC), San Francisco, CA, June 13-14 & Dallas, TX, November 15-16, 2017. This training course focuses on groundwater characterization and discusses (1) the impacts of subsurface heterogeneity on the investigation and cleanup of groundwater and related media, (2) the need for scale-appropriate measurements and adequate data density, and (3) the tools and strategies that are available to overcome the impacts of subsurface heterogeneity. After taking this course, participants will be armed with information that will allow them to improve their subsurface investigation approaches and develop more realistic and comprehensive conceptual site models (CSM). CSMs developed based on HRSC strategies and tools will decrease site uncertainty, improve the remedy selection process for groundwater remedies, and better enable the evaluation, design, and implementation of targeted in situ and ex situ groundwater remedies. The Groundwater HRSC course is an advanced 2-day course. The recommended audience includes EPA, federal, state, tribal and private industry technical project managers, practitioners and other stakeholders involved in groundwater investigation and remediation.

Best Practices for Site Characterization Throughout the Remediation Process, Dallas, TX, August 1-3 & New York, NY, September 12-14, 2017. This training course is based on best management practices (BMP) implemented by the U.S. EPA, partnership organizations, federal and state partners, and consultants. Participants will learn how to streamline projects in a legal, technically sound, and cost-effective manner. By taking the course, participants achieve the following objectives: integrate best practices into traditional project activities; effectively collect and communicate critical project information; design dynamic work strategies; recognize and overcome the challenges presented while implementing a dynamic work strategy; and use BMPs to support all phases of the environmental cleanup life cycle.
