Priorities List Sites is designed to assist RPMs in understanding the requirements for
achieving and documenting accomplishments for site close out. The EPA Office of
Superfund Remediation and Technology Innovation (OSRTI) issued an updated version
of the Close Out Procedures guidance in May 2011. The guidance describes the
recommended process for accomplishing and documenting four key milestones for sites
on the National Priorities List (NPL): remedial action completion, construction
completion, site completion and site deletion (including partial deletion). This session
assists new RPMs in understanding the requirements for each accomplishment. More
experienced RPMs learn about the important changes that were made in the revised
guidance. For more information and to register, see httn://ciu-in.om/iive .

Arsenic - Interventions - April 15, 2013,12:00PM-2:00PM EDT (16:00-18:00 GMT).

In the first presentation SRP Researcher Joseph Calo, Ph.D., will discuss his team's
latest research on developing a spouted vessel/fixed bed filter system for the removal of
arsenic from water. The system uses zero-valent iron (ZVI) particles circulating in a
spouted vessel that continuously generates active colloidal iron corrosion products.
These corrosion products are generated by the "self-polishing" action between ZVI
source particles rolling in the moving bed that forms on the conical bottom of the
spouted vessel. This action also serves as a "surface renewal" mechanism for the
particles and provides for maximum ZVI material utilization. The colloidal material

produced in this fashion is continuously captured and concentrated in an internal fixed
bed filter where arsenic complexation occurs. This system has been shown to reduce
100 ug/L of arsenic to below detectable levels in less than an hour. Calo's presentation
will focus on the spouted vessel/fixed bed filter system for removing arsenic from water,
and he will share his most recent research results. In the second presentation SRP
Researcher Girish Srinivas, Ph.D., will discuss research being conducted by TDA
Research, Inc. (TDA) to develop a cost effective, simple point-of-use (POU) water
purifier. The purifier is based on capacitive deionization (CDI) for removing problematic
toxic ionic contaminants from well water not attached to a large public waterworks.
TDA's CDI technology can effectively remove perchlorate, nitrate, arsenic, lead, and
other harmful inorganic ions from well water to meet EPA drinking water specifications
in a simple, DC powered device. The technology can be used for POU applications
(e.g. under the sink) in homes that use well water or in developing countries at well
sites, where, if power is unavailable, it can be operated using a simple photovoltaic
system. For more information and to register, see http://ciu-in.ora/iive .

ITRC Project Risk Management for Site Remediation - April 16, 2013,
2:00PM-4:15PM EDT (18:00-20:15 GMT). Remediation Risk Management (RRM) is a
course of action through which all risks related to the remediation processes (site
investigations, remedy selection, execution, and completion) are holistically addressed
in order to maximize the certainty in the cleanup process to protect human health and
the environment. Remediation decisions to achieve such a goal should be made based
on threshold criteria on human health and ecological risks, while considering all the
other potential project risks. Through this training course and associated ITRC
Technical and Regulatory Guidance Document: Project Risk Management for Site
Remediation (RRM-1, 2011), the ITRC RRM team presents tools and processes that
can help the site remediation practitioner anticipate, plan for, and mitigate many of the
most common obstacles to a successful site remediation project. Examples of project
risks include remediation technology feasibility risks; remedy selection risks; remedy
construction, operation and monitoring risks; remedy performance and operations risks;
environmental impacts of systems during their operation; worker safety risk, human
health and ecological impacts due to remedy operation; as well as costs and schedules
risks including funding and contracting issues. For more information and to register,

ITRC Incorporating Bioavailability Considerations into the Evaluation of
Contaminated Sediment Sites - April 18, 2013,11:00AM-1:15PM EDT (15:00-17:15
GMT). ITRC's web-based Technical and Regulatory Guidance, Incorporating
Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites
(Sed-1, 2011) and associated Internet-based training are intended to assist state
regulators and practitioners with understanding and incorporating fundamental
concepts of bioavailability in contaminated sediment management practices. This
guidance and training describe how bioavailability considerations can be used to
evaluate exposure at contaminated sediment sites, the mechanisms affecting
contaminant bioavailability, available tools used to assess bioavailability, the proper
application of those tools and how bioavailability information can be incorporated into
risk-management decisions. This guidance and training also contain summaries of
case studies where bioavailability has been assessed and considered in the
contaminated sediment remedial decision making process. This guidance and training
provide insight on how bioavailability assessments can be used to understand, mitigate
and manage risk at a contaminated sediment site, often at a reduced overall project
cost. For more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

ITRC Green & Sustainable Remediation - April 23, 2013, 2:00PM-4:15PM EDT

-------
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. For more
information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

NARPM Presents...Environmental Statutes for RPMs - April 24, 2013,
1:00PM-3:00PM EDT (17:00-19:00 GMT). This internet seminar provides a basic
history and describes the major provisions of EPA statutes, such as the Federal
Insecticide, Fungicide, and Rodenticide Act (FIFRA), the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA), the Emergency
Planning and Community Right-to-Know Act (EPCRA), the Safe Drinking Water Act
(SDWA) and the Toxic Substances Control Act (TSCA). Participants learn how statutes
and regulations are developed. The session provides an overview of U.S.
environmental regulations that have been created to control, manage or modify our
activities and the effects of these regulations on the health of human beings and the
natural environment. Additionally, the session provides a brief history of environmental
laws and the origins of EPA. For more information and to register, see http://ciu-in.ora/iive .

ITRC Integrated DNAPL Site Strategy - April 25, 2013,11:00AM-1:15PM EDT
(15:00-17:15 GMT). The 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; and
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. For more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

The Management of Brownfields Redevelopment: A Guidance Note (2010). This
World Bank guidance note is primarily addressed to local or regional public authorities
responsible for the management of brownfields in the transition economies of Central
and Eastern Europe. The main impetus for this work is to offer perspectives and
solutions to one of the many challenges cities are facing, especially in post-socialist
emerging market environments, where urban brownfields are a major hurdle to
transforming local economies. Brownfields are understood here as derelict or
underused sites with real or perceived contamination problems that create an obstacle
to their development potential. As such, these sites represent both a problem and an
opportunity. View or download at
