CEC Preliminary Assessment/Site Inspection (PA/SI) Webinar Series - July 2, 7, 9,
11,14, 21, 28, 30. The CERCLA Education Center (CEC) is offering a nine-part
Preliminary Assessment and Site Inspection (PA/SI) Webinar Series in June and July
2014. PA/SI is an intermediate training course designed for personnel who are required
to compile, draft and review PA, SI and HRS documentation records and packages
submitted for sites proposed for the National Priorities List (NPL). This course is open
to EPA, federal, state, tribal and contractor personnel who support site
investigation programs. The PA/SI Webinar Series provides an introduction to the
Superfund site assessment process and describes the preliminary assessment and site
inspection phases of this process. The course will incorporate a mix of lecture and
exercises using Quickscore for each of the four pathways. The objective of the exercise
is to give participants the opportunity to evaluate and score PA information using the
HRS Quickscore software. Participants will use information from a fictitious site to (1)
evaluate and calculate a preliminary HRS score, and (2) develop release and target
hypotheses that should be pursued in an SI. In order to receive credit for taking the
course, participants must participate in each session. If you are unable to make one of
the sessions, archived versions will be made available at www.ciu-in.nm that you can take
to receive credit for the missed live session. In order to receive credit for a missed
session, you must complete the missed session within 2 months of the originally
scheduled date and submit an evaluation form from that archived module. For more
information and to register, see httn://ciu-in.om/iive .
ITRC LNAPL Training Parts 1, 2, and 3 - July 8,15, 22. 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 http://www.itrcweb.ora or http://ciu-in.ora/iive .
Reuse Opportunities at Capped Superfund Sites - July 16, 2014, 2:00PM-4:00PM
EDT (18:00-20:00 GMT). Former landfills, abandoned dumps and other contaminated
sites throughout the United States were once thought to be of limited or no value.
Today, these sites are being transformed into viable commercial and industrial
developments, recreational areas and wildlife areas. With forethought, coordination
with regulatory agencies, and effective planning, communities and site stakeholders can
return sites to productive use without jeopardizing the effectiveness of a remedial cap
put into place to protect human health and the environment. Reuse can provide
long-term benefits for the local community, the local government, site owners and even
for EPA through continued site stewardship after remedial efforts are complete. This
webinarwill share examples and lessons learned from the effective assessment and
successful reuse of capped sites. For more information and to register, see

ITRC Incorporating Bioavailability Considerations into the Evaluation of
Contaminated Sediment Sites - July 17, 2014,11:00AM-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 .
If Cells Could Talk, What Would They Tell Us About Chemical Exposure?
Applications of Cell-Based Bioanalytical Methods - August 11, 2014,
1:00PM-3:00PM EDT (17:00-18:00 GMT). This two-part seminar will feature Dr.
Michael Denison of the University of California Davis Superfund Research Program
(SRP) and Dr. Scott Boitano from the University of Arizona SRP and will focus on
applications of cell-based bioanalytical methods to better understand environmental
toxicities. For more information and to register, see http://ciu-in.ora/iive .

Climate Change Adaptation Technical Fact Sheet: Landfills and Containment as
an Element of Site Remediation (EPA 542-F-14-001). In February 2013, the U.S.
EPA released the draft U.S. Environmental Protection Agency Climate Change
Adaptation Plan. The plan examines how EPA programs may be vulnerable to a
changing climate and how the Agency can accordingly adapt in order to continue
meeting its mission of protecting human health and the environment. EPA's Superfund

Program has undertaken associated efforts to identify potential impacts of climate
change on site remediation projects and to identify adaptation strategies. A key
component of the Superfund climate change adaptation action plan involves developing
tools that can help project managers and other cleanup stakeholders to identify,
prioritize and implement site-specific measures for increasing remedy resilience to
climate change impacts. This fact sheet addresses contaminated site remedies
involving landfills and source containment systems. It is intended to serve as an
adaptation planning tool by (1) providing an overview of potential climate change
vulnerabilities and (2) presenting possible adaptation measures that may be considered
to increase a remedy's resilience to climate change impacts. This tool was developed
in context of the Superfund Program but its concepts may apply to site cleanups
conducted under other regulatory programs or through voluntary efforts (May 2014, 8
pages).To learn more about climate change adaptation in the Superfund Program, visit

EPA Releases Final Risk Assessment on Trichloroethylene (TCE). The final risk
assessment for TCE identified health risks from TCE exposures to consumers using
spray aerosol degreasers and spray fixatives. It also identifies health risks to workers
when TCE is used as a degreaser in small commercial shops and as a stain removing
agent in dry cleaning. The final TCE risk assessment was developed as part of the
agency's Toxic Substances Control Act (TSCA) Work Plan, which identified chemicals
for review and assessment of potential risks to people's health and the environment.
EPA developed the draft TCE risk assessment based on the best available information
and finalized the assessment after careful consideration of comments from the public
and experts during an independent, scientific peer review of the assessment. TCE is
the first chemical to complete the work plan risk assessment process under TSCA. EPA
is conducting a workshop from July 29-30, on potential TCE degreaser alternatives and
risk reduction approaches. EPA will conduct other activities to address TCE uses as a
stain removing agent in dry cleaning and as a clear protective spray fixative. For more
information on the TCE risk assessment, the July 29-30 public workshop, and TSCA
workplan chemical, see http://www.epa.aov/oppt/existinachemicals/pubs/riskassess.html .

Getting Started - Guidance on Preparing Your Brownfields Area-Wide Planning
Grant Proposal. Some applicants find it difficult to prepare their grant proposals within
60 days, the typical amount of time the Request for Proposals (RFP) allows until the
proposals are due. However, there are several activities that applicants can perform in
advance of the RFP being made publically available. Potential applicants for our
Brownfields Area-Wide Planning grants can get a head start with proposal preparation
by familiarizing themselves with the document below, discussing possible projects with
local partners and stakeholders, pulling together important information, and working with
their local Brownfields contacts to resolve any questions about brownfields site
eligibility. We hope this information will
help applicants prepare a thorough, well-organized, and timely proposal (June 2014, 3
pages). View or download at
